The mechanical and touch methods require people to pull or touch the door handle, the remote control method requires carrying a remote control or mobile phone and other control devices, and the distance measurement requires people to sweep at a fixed position due to the fixed direction. The sweeping of other objects may trigger by mistake. The above-mentioned unlocking methods all have great limitations, and the convenience of door unlocking needs to be further improved. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a car door handle capable of collecting gesture signals, so as to solve the technical problem that the traditional unlocking method has large limitations.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a car door handle that can realize gesture signal collection, including a plastic shell, a PCB board fixedly connected to the plastic shell, and at least one millimeter wave radar, a power connector, and a communication connector are arranged on the PCB board.

[0005] As a preferred solution, at least one indicator light is also connected to the PCB board, and a window corresponding to the indicator light is provided on the plastic housing.

[0006] As a preferred solution, a control chip is also provided on the PCB board, and the millimeter wave radar is connected to the control chip.

[0007] As a preferred solution, the number of the millimeter wave radars is four, arranged in a matrix.

[0008] The beneficial effect of the utility model is that the utility model installs a PCB board inside the plastic shell of the door handle and sets a millimeter wave radar on the PCB board. The millimeter wave radar can detect human gestures and send action signals to the driving computer. The driving computer can judge the owner's different instructions such as unlocking, opening the door, closing the door, locking the car, etc. according to the gestures, and control the electronic lock on the door to execute the instructions, so as to realize remote unlocking, opening the door, closing the door, locking the car, etc. Since the millimeter wave radar has a wide detection range, it can solve the technical problem that the traditional unlocking method has large limitations and improve the convenience of unlocking the door.

[0012] The specific implementation scheme of the utility model is described in detail below in conjunction with the accompanying drawings.

[0013] like Figure 1 As shown, the car door handle capable of collecting gesture signals includes a plastic shell 1, a PCB board 2 fixedly connected to the plastic shell 1, and the PCB board 2 is provided with four matrix-arranged millimeter-wave radars 3, a power connector 4, and a communication connector 5. The communication connector 5 is connected to the car LIN bus through a signal line, and the power connector 4 is connected to the car power supply through a wire.

[0014] The user enters the gestures for unlocking, opening the door, closing the door and locking the car in advance in the on-board computer (ECU), and then can remotely control the car through the above-mentioned car door handle. Since the millimeter-wave radar 3 is arranged in the car door handle, the detection range is wide. The user can make gestures for unlocking, opening the door, closing the door and locking the car at any position within the detection range of the millimeter-wave radar 3, and the on-board computer can analyze the user's instructions and execute the instructions for unlocking, opening the door, closing the door and locking the car.

[0015] In practical applications, the number of millimeter-wave radars 3 used can be one or more. The more millimeter-wave radars 3 are used, the higher the detection accuracy is, and more gestures can be distinguished, but it will also increase the computing power of the on-board computer.

[0016] In order to give feedback to the user and let the user know the execution result of the instruction by the driving computer, in this embodiment, an indicator light 6 is preferably connected to the PCB board 2, and a window 7 corresponding to the indicator light 7 is provided on the plastic housing 1. When the user makes an instruction within the detection range of the millimeter wave radar 3 and the driving computer cannot determine the instruction, the indicator light 7 can flash to remind the user, and when the driving computer determines the instruction and executes the instruction, the indicator light 7 can be turned on for a period of time and then turned off to remind the user that the operation is completed.

[0017] like Figure 1As shown, in this embodiment, a control chip 8 is preferably arranged on the PCB board 2, and the millimeter-wave radar 3 is connected to the control chip 8. The control chip 8 is arranged on the PCB board 2 to reduce the data processing load of the on-board computer. The detection result of the millimeter-wave radar 3 is directly sent to the control chip 8. After being processed by the control chip 8, the processing result is directly sent to the on-board computer for data comparison to determine the instruction. In this way, the on-board computer does not need to calculate the detection result of the millimeter-wave radar 3, avoiding the problem of interference and affecting the accuracy when the detection result of the millimeter-wave radar 3 is sent to the on-board computer via the longitudinal LIN.

[0018] The working principle of the utility model is: by installing a PCB board 2 inside the plastic housing 1 of the door handle, and setting a millimeter wave radar 3 on the PCB board 2, the millimeter wave radar 3 can detect human gestures and send action signals to the driving computer, and the driving computer can judge the owner's different instructions such as unlocking, opening the door, closing the door, locking the car, etc. according to the gestures, and control the electronic lock on the door to execute the instructions, so as to realize remote unlocking, opening the door, closing the door, locking the car, etc. Since the millimeter wave radar 3 has a wide detection range, it can solve the technical problem that the traditional unlocking method has large limitations and improve the convenience of unlocking the door.

[0019] The above embodiments are only illustrative of the principles and effects of the invention, as well as some embodiments of its application, and are not intended to limit the invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the invention, and all of these belong to the protection scope of the invention.
