Vehicle door pull comprising an antenna arrangement
A vehicle door handle includes a handle and a handle mount, wherein the handle is mounted in the handle mount. The handle is formed as an elongated body which has first and second end sections and a grip section disposed in the middle of the handle between the end sections. Bearing sections of the first and second end sections extend into the handle mount and are supported therein. An antenna with a control circuitry is a disposed in an inner hollow chamber in the handle. The control circuitry has signal lines which go to the handle mount. The antenna is configured as a high frequency antenna for signal transmission in the high frequency range. The control circuitry is coupled to the antenna for transmitting and receiving. The antenna is received outside the grip section in an end section of the handle.
1. A vehicle door handle that is to be installed on a motor vehicle, wherein the vehicle door handle includes a handle and a handle mount, wherein the handle is mounted in the handle mount, wherein the handle is formed as an elongated body that has a first end section and a second end section, and a grip section disposed between the end sections in a middle section of the handle, wherein the first end section and the second end section each have bearing sections, wherein the bearing sections of the first end section and the second end section extend into the handle mount and are supported therein, wherein an antenna with a control circuitry is disposed in an inner hollow chamber in the handle, and wherein the control circuitry has signal lines, which go to the handle mount, wherein the antenna is configured as a high-frequency antenna for signal transmission in the high-frequency range, and the control circuitry is coupled to the antenna for transmitting and receiving, wherein the antenna is received outside the grip section in an end section of the handle so that the antenna is located in a section of the handle where a shielding of the antenna by a hand of a user grasping the grip section of the handle is unlikely to occur.
2. The vehicle door handle according to claim 1 , wherein the handle is supported in the handle mount such that it can move, wherein the first end section of the handle is configured as an actuating section, and the second end section is configured as a pivotal section, such that the pivotal section and the actuating section are disposed on opposite ends of the handle, wherein the bearing section of the actuating section extends into the handle mount and is actively connected mechanically there to actuating means, in order to transfer a movement of the handle to the actuating means, wherein the bearing section of the pivotal section is received in a pivot bearing of the handle mount, such that the handle can pivot in the pivot bearing in a movement guided by the bearing section and the pivot bearing, wherein the antenna is received in the pivotal section of the handle.
3. The vehicle door handle according to claim 1 , wherein the antenna is configured for signal transmission at a frequency in the range of 2 GHz to 5 GHz.
4. The vehicle door handle according to claim 3 , wherein the antenna is configured for transmission according to a Bluetooth standard.
5. The vehicle door handle according to claim 1 , wherein the antenna is formed as a conductor path on a printed circuit board.
6. The vehicle door handle according to claim 5 , wherein the antenna is disposed, together with the control circuitry, on the same printed circuit board.
7. The vehicle door handle according to claim 1 , wherein the antenna is formed as a separate component at a spacing to the control circuitry.
8. The vehicle door handle according to claim 1 , wherein the end sections are formed as integral extensions of the grip section, wherein each end section is formed by a section of the handle that has a length of less than 30% of the overall length of the handle.
9. The vehicle door handle according to claim 8 wherein each end is formed by a section of the handle that has a length of less than 20% of the overall length of the handle.
10. The vehicle door handle according to claim 1 , wherein the spacing between the handle and the handle mount over the entire grip section is greater than in the end sections.
