Description

Technical Field

[0001] The present disclosure relates to the technical field of electronic equipment, and in particular to a vehicle door induction opening device and a vehicle. Background Art

[0002] With the application of intelligent automotive technology and the development of intelligent industry, cars are becoming increasingly intelligent, comfortable, and convenient. For example, traditional methods for opening and closing tailgates include key buttons, buttons on the outside of the tailgate, and other push-button methods. These methods can be inconvenient in certain scenarios, such as when hands are full and unable to reach the tailgate switch. The same problem also exists with the vehicle's side doors. The foot-operated tailgate opening and closing sensor device can solve this problem. It allows users to open the trunk or side door without using their hands, making them much more convenient to open and close.

[0003] The pedal-operated car tailgate opening and closing sensor device usually includes a housing and a projection module and a sensing module arranged on the housing. The pedal-operated car tailgate opening and closing sensor device needs to be installed at a corresponding position on the vehicle. The projection module can project a light spot on the ground. When the projection area of ​​the projection module is blocked, the sensing module will be triggered, and the sensing module will send a signal to the vehicle, and the vehicle can control the corresponding door (tailgate or side door) to open. When installing the pedal-operated car tailgate opening and closing sensor device, it is usually necessary to open a hole in the corresponding shell part on the vehicle body, place the pedal-operated car tailgate opening and closing sensor device in the internal cavity of the shell, and make the projection end of the projection module and the sensing end of the sensing module accurately face the opening, so that the door sensing opening device can operate normally and effectively. This increases the difficulty of assembling and positioning the pedal-operated car tailgate opening and closing sensor device. If the assembly position of the pedal-operated car tailgate opening and closing sensor device is slightly deviated, the opening and the projection module or the sensing module are staggered, which will cause the pedal-operated car tailgate opening and closing sensor device to fail to work normally and effectively.

[0053] It should be noted that these drawings and textual descriptions are not intended to limit the conceptual scope of the present invention in any way, but rather to illustrate the concept of the present invention for those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0054] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0055] like Figures 1 to 14 As shown, an embodiment of the present application provides a vehicle door sensor opening device, comprising: a housing, a window sheet 3, a projection module 1, and a sensing module 2. The housing has a cavity and a through-hole communicating with the cavity. A circular rib 41 is provided on the outer wall of the housing, and the through-hole is located inside the circular rib 41. The projection module 1 is disposed within the cavity, and light projected by the projection module 1 exits the housing through the through-hole. The sensing module 2 is disposed within the cavity, with the sensing end of the sensing module 2 facing the through-hole. The window sheet 3 is embedded in the circular rib 41, and the window sheet 3 covers the through-hole.

[0056] The door sensor opening device of the present application is provided with a circular rib 41, which facilitates rapid assembly of the door sensor opening device. During the specific assembly process, it is only necessary to use a drill of appropriate specifications to drill a circular hole in the shell portion somewhere on the vehicle body, place the door sensor opening device within the cavity of the shell portion, and insert the circular rib 41 into the circular hole so that the shell support is limited to the circular hole. The shell can then be secured with fasteners to achieve rapid positioning and assembly of the door sensor opening device.

[0057] In some possible implementation schemes, the thickness of the window piece 3 is less than the height of the circular rib 41, the window piece 3 is attached to the outer wall surface of the shell, and there is a gap between the window piece 3 and the upper edge of the circular rib 41 to ensure that the window piece 3 is slightly lower than the upper edge of the circular rib 41 after assembly, thereby preventing the entire window surface from being scratched during the assembly, testing, packaging, transportation, and use of the product, thereby protecting the window surface.

[0058] In some possible implementations, see Figure 6 As shown, the through hole includes a projection avoidance hole 42 and a sensing avoidance hole 44. Light projected by the projection module 1 is emitted from the housing through the projection avoidance hole 42. The sensing end of the sensing module 2 faces the sensing avoidance hole 44. The window piece 3 covers the projection avoidance hole 42 and the sensing avoidance hole 44. The fact that a single window piece 3 can cover both the projection avoidance hole 42 and the sensing avoidance hole 44 simplifies the structure and improves assembly efficiency.

[0059] In some possible implementations, see Figure 6 and Figure 7 As shown, the projection avoidance hole 42 is a circular hole, and the sensing avoidance hole 44 is an elongated hole. The two ends of the elongated hole along the length direction are used to avoid the detection signal emitted by the sensing module 2 and the reflected signal of the detection signal, respectively. The projection avoidance hole 42 is located on one side of the sensing avoidance hole 44 along the width direction, and the projection avoidance hole 42 is not located on the extension line of the sensing avoidance hole 44. As a result, the projection avoidance hole 42 is relatively close to both the transmitting and receiving sides of the sensing module 2. The sensing area of ​​the sensing module 2 and the projection area of ​​the projection module 1 have a high degree of overlap, thereby improving product sensing accuracy. In a preferred embodiment, the distance between the projection avoidance hole 42 and the two ends of the sensing avoidance hole 44 is equal. That is, the projection avoidance hole 42 is best located on the mid-perpendicular line of the sensing avoidance hole 44.

[0060] In some possible implementations, the window sheet 3 has a first light-transmitting portion and a second light-transmitting portion. When the window sheet 3 is embedded inside the annular rib 41, the first light-transmitting portion covers the projection avoidance hole 42, and the second light-transmitting portion covers the sensing avoidance hole 44. The window sheet 3 is provided with light-transmitting portions only at locations corresponding to the projection avoidance hole 42 and the sensing avoidance hole 44. The other areas of the window sheet 3 can be provided as opaque areas, thereby shielding the internal structure and beautifying the appearance. The opaque areas on the window sheet 3 can be formed by providing a silk-screen layer on the window sheet 3.

[0061] In some possible implementations, see Figure 7 As shown, the annular rib 41 encloses a embedding groove 49, a positioning portion 45 is provided in the embedding groove 49, and a positioning matching portion 31 is provided on the window piece 3. When the window piece 3 is embedded in the embedding groove 49, the positioning matching portion 31 and the positioning portion 45 are limitedly matched, so that the first light-transmitting portion covers the projection avoidance hole 42 and the second light-transmitting portion covers the sensing avoidance hole 44.

[0062] The window 3 is provided with two light-transmitting portions, so the installation of the window 3 requires orientation. The positioning and fitting portion 31 can be a cut edge designed on the window 3. The positioning portion 45 can be a small protrusion designed in the embedding groove 49. When the two are assembled together, the cut edge fits in a limited position with the small protrusion, thereby achieving rapid positioning of the window 3 and the embedding groove 49.

[0063] In some possible implementations, see Figures 8 to 10 As shown, a plurality of claws 46 are provided on the inner wall of the shell around the projection avoidance hole 42 , and the claws 46 enclose a limiting space. The projection module 1 is arranged through the limiting space, and the claws 46 abut against the outer wall of the projection module 1 .

[0064] Exemplarily, four claws 46 can be set on the edge of the projection avoidance hole 42, and the claws 46 are distributed along the circumference. The outer edge 121 of the front lens of the projection module 1 is inserted into the limited space formed by the claws 46, and the claws 46 fix the projection module 1 by interference fit.

[0065] In some possible implementations, see Figure 1 、 Figure 6 and Figure 8 As shown, the door sensing opening device includes a lens gasket 5, and the inner wall of the shell is provided with an outward expansion groove 43 along the edge of the projection avoidance hole 42. The outward expansion groove 43 is connected to the projection avoidance hole 42, and the inner diameter of the outward expansion groove 43 is larger than the inner diameter of the projection module 1. The lens gasket 5 is embedded in the outward expansion groove 43, and one end of the projection module 1 contacts the lens gasket 5. The lens of the projection module 1 can be a lens with threaded focal length adjustment. If the pressure applied along the axis of the lens is too large during assembly, the focal length will change, which may affect the projection performance of the product. The lens gasket 5 of the present application can be made of elastic rubber material, which is installed and fixed in the outward expansion groove 43 so that the lens at the front end of the projection module 1 is in contact with the lens gasket 5. The lens gasket 5 plays the role of buffering and protecting the lens.

The three positioning and fixing columns 122 at the tail of the projection module 12 are inserted into the three positioning and fixing holes 112 of the corresponding LED module 11, and the projection module 12 and the LED module 11 are fixed together by glue or heat anchoring.

[0069] A thermal pad 10 is installed between the LED module 11 and the upper housing 4a. One side of the thermal pad 10 is attached to the upper housing 4a, and the other side is attached to the back panel of the LED module 11. The upper housing 4a presses the thermal pad 10 against the back panel of the LED module 11. The upper housing 4a is made of metal and has heat dissipating fins on the back to dissipate heat conducted by the thermal pad 10.

[0070] The sensing module 2 may be a radar module, which is fixed to the mainboard 8 by screws. The radar module signal can pass through the sensing gap on the lower housing 4b and through the window 3 to the outside of the device.
