[0023] The utility model will be described in detail below with reference to the drawings and in combination with embodiments.

[0024] A kind of electric car handle grip detection device, as shown in Figs. 1 to 4 It includes frame 1, handlebar cover 2 arranged on frame 1 and detector 3 arranged on handlebar cover 2;Frame 1 is provided with wiring hole 8 at the position corresponding to detector 3;Transparent window 4 is provided on detector 3, and photosensitive resistance RG1 and reflective photoelectric switch U1 are provided in detector 3 at the position corresponding to transparent window 4, the cathode of reflective photoelectric switch U1 is grounded, the anode is connected with power supply VCC through resistance R1, the emitter is grounded through resistance R2, the collector is connected with power supply VCC through photosensitive resistance RG1, and the collector of reflective photoelectric switch U1 is the output end of detector 3.

[0025] The handlebar cover 2 can be fixed on the frame 1 by conventional means such as adhesives, and the frame 1 can be installed on the body of the electric bicycle in a conventional manner. The reflective photoelectric switch U1 can be a conventional reflective infrared photoelectric tube ITR8307, and the photoresistor RG1 can have a resistance of about 1K in a sunny environment and about 200K in a dark environment. Those skilled in the art can also select appropriate reflective photoelectric switch U1 and photoresistor RG1 according to actual needs to achieve detection of the human hand, which will not be described here.

[0026] Preferably, the power supply VCC is +5V, the resistor R1 is 100R, and the resistor R2 is 5.1K. The +5V power supply is a conventional power supply with more common sources, which can be directly powered from the controller on the electric vehicle, resulting in lower modification costs and more stable power supply. Those skilled in the art can also select other specifications of power supply VCC, resistor R1, resistor R2, and photoresistor RG1 according to actual needs, which will not be described here.

[0027] In actual application, the power supply VCC, ground, and output terminal can be connected to the existing controller of the electric bicycle to achieve power supply and signal transmission, and to determine whether the rider holds the handlebar according to the high and low levels. In actual use, the user can also be reminded or braked by sending information about whether the user has one hand or both hands away from the handlebar to the vehicle controller. The main innovation of the present application is the improvement of the structure of the detector 3, and it does not involve the improvement of the electric bicycle controller. Those skilled in the art can select appropriate existing controllers according to actual needs to achieve power supply and signal reception of the detector 3, which will not be described here.

[0028] Specifically, low level indicates that the rider holds the handlebar, and high level indicates that the rider does not hold the handlebar. When no grip action is detected, in a sunny environment, the resistance of the photoresistor RG1 is about 1K, and the output voltage of the output terminal V-OUT of the detector 3 is VCC (i.e. +5V, high level); in a dark environment, the resistance of the photoresistor RG1 is about 200K, and the output voltage of the output terminal V-OUT of the detector 3 is VCC (i.e. +5V, high level). When grip action is detected, whether the external environment is sunny or not, the resistance of the photoresistor RG1 is about 200K, and the output voltage of V-OUT is about 0.1V (i.e. low level).

[0029] Therefore, by using the reflective photoelectric switch U1 in cooperation with the photoresistor RG1, whether the handlebar is held or not during the riding process can be effectively detected during the day or at night, and the accuracy is higher. By judging that the hand holding the handlebar cover 2 of the electric vehicle causes the detector 3 to emit different signals, the unsafe riding behavior of the personnel during the riding process can be effectively monitored and prevented, which is beneficial to guide the user to ride safely, thereby ensuring the safety of driving.

[0030] Preferably, the transparent window 4 is made of transparent acrylic plate, transparent PC plate or transparent PVC plate. Exemplarily, the detector 3 includes a shell and an integrated circuit board 5 installed in the shell, the transparent window 4 can be fixed on the shell by conventional methods such as adhesive, the photoresistor RG1 and the reflective photoelectric switch U1 are welded on the integrated circuit board 5, and a through hole for facilitating wiring can be arranged on the shell of the detector 3 to facilitate the assembly and passing of the cable. In actual use, the connection between the shell and the transparent window 4 can also be achieved by using hot melt welding and other technologies to improve the overall sealing performance of the detector 3 and ensure the safety and reliability of the electronic devices in the detector 3.

[0031] In actual application, the transparent window 4 extends out of the handlebar cover 2. By using transparent acrylic plate, transparent PC plate or transparent PVC plate to make the transparent window 4, not only the light transmission requirement of the transparent window 4 can be met, but also the cost is low, the assembly is easy, and the wear resistance and corrosion resistance are good, which is beneficial to improve the reliability of the detector 3 and reduce the cost of the detector 3.

[0032] Preferably, the handlebar cover 2 is provided with anti-skid lines at a position different from the detector 3. By arranging the anti-skid lines, the rider can hold the handlebar cover 2 more stably, and the hand can continuously and stably block the transparent window 4, so that the detector 3 can continuously detect whether the rider holds the handlebar.

[0033] Preferably, the handlebar cover 2 is provided with an assembly hole for assembling the detector 3, one end of the detector 3 extending into the assembly hole is provided with a positioning part 6, an inner side of the handlebar cover 2 corresponding to the position of the assembly hole is provided with a positioning groove matched with the positioning part 6, and the positioning groove is communicated with the assembly hole.

[0034] In actual application, the detector 3 can also be installed and fixed on the handlebar cover 2 by conventional methods such as adhesive. By using the positioning part 6 on the detector 3 to cooperate with the positioning groove on the handlebar cover 2, the stability of the detector 3 on the handlebar cover 2 can be improved, and the detector 3 can be prevented from falling off during use, which is beneficial to further improve the reliability of the detection device.

[0035] Preferably, the frame 1 is provided with an assembly groove 7 matched with the positioning part 6, the assembly groove 7 is communicated with the wire hole 8, and the length direction of the assembly groove 7 is same with the length direction of the handlebar sleeve 2. In actual use, the assembly groove 7 of the frame can also be matched with the positioning part 6, at this time, the detector 3 can form a stable connection structure between the handlebar sleeve 2 and the frame 1, which is not only beneficial to further improve the stability of the detector 3, but also beneficial to improve the connection stability between the handlebar sleeve 2 and the frame 1. Meanwhile, by matching the positioning part 6 with the assembly groove 7, the position of the detector 3 can also be positioned during the assembly of the handlebar sleeve 2, which reduces the alignment and assembly difficulty of the handlebar sleeve 2, and is also beneficial to reduce the production and assembly cost of the device.

[0036] Specifically, by arranging the long strip-shaped assembly groove 7 on the frame 1, the installation of the handlebar sleeve 2 is also facilitated. During installation, the cable connected with the detector 3 can be first inserted into the wire hole 8 and placed in the assembly groove 7, and then the handlebar sleeve 2 is moved along the assembly groove 7 until the assembly of the handlebar sleeve 2 is completed, which reduces the assembly difficulty of the handlebar sleeve 2, and also improves the stability of the handlebar sleeve 2 after assembly.

[0037] The electric bicycle handle grip detection device has the advantages of low cost, simple structure, easy assembly, good reliability, high detection accuracy, etc. By arranging the detector on the handlebar sleeve and cooperating the reflective photoelectric switch U1 and the photosensitive resistor on the detector, the influence of external environmental light on detection can be effectively reduced, which is beneficial to more accurately judge the riding state of the user and improve the detection accuracy.

[0038] The above only describes the preferred embodiments of the present application, and does not limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
