Technical Field

[0001] This utility model relates to the field of vehicle lighting technology, specifically to a touch-sensitive vehicle lighting marking installation and fixing structure. Background Technology

[0002] With the advancement of technology, the development of automotive lights is accelerating, and their electrification and intelligence are increasing, posing new challenges to the research and design of automotive lighting components.

[0003] Currently, some cars on the market are equipped with headlight indicators; however, these indicators are relatively simple in function, usually only providing illumination and lacking additional functions such as unlocking the trunk, which does not meet the needs of OEMs and consumers. Furthermore, existing headlight indicators can only be controlled via mechanical switches (such as knobs or buttons) or the central control screen installed inside the vehicle, and cannot be operated from outside, resulting in a poor user experience.

[0004] To address this, we developed a new type of touch-sensitive headlight indicator, giving it capacitive touch functionality. This allows users to unlock the trunk and perform other functions by touching the headlight indicator from outside the vehicle. Utility Model Content

[0005] One of the objectives of this utility model is to provide a touch-sensitive vehicle light sign installation and fixing structure, including a touch PCB, a sign cover plate, and a sign bracket. The sign bracket is provided with an installation groove, and the touch PCB is fixedly connected to the sign cover plate. The resulting assembly is fixed in the installation groove of the sign bracket.

[0006] In the above solution, the touch PCB is a capacitive touch PCB. An LED light source is also provided on the touch PCB; touching it will turn the LED light on or off. Furthermore, the touch PCB is electrically connected to the front or rear trunk lock; touching it will not only illuminate the LED light but also unlock the front or rear trunk.

[0007] In the above solution, two (or more) thermoplastic positioning posts are provided on the back of the sign cover, and matching positioning holes are provided on the touch PCB. The touch PCB and the sign cover are positioned and thermoplastic connected through the thermoplastic positioning posts and positioning holes.

[0008] In the above scheme, the sign cover is fixedly connected to the sign bracket by a snap fastener.

[0009] In the above solution, a buckle with a slot is provided on the back of the sign cover. A matching buckle protrusion is provided in the mounting groove of the sign bracket. The reliable fixed connection between the sign cover and the sign bracket is achieved through the cooperation between the slot and the protrusion on the buckle.

[0010] In the above scheme, the number of buckles is 2-4, and the buckles are arranged on the back of the sign cover in a symmetrical, triangular, or rectangular manner.

[0011] In the above solution, a clearance groove for the clearance buckle is also provided on the touch PCB.

[0012] In the above solution, the mounting and fixing structure also includes a decorative bracket with a support hole. The sign bracket is fixed to the back of the decorative bracket, and the assembly formed by the sign cover and the touch PCB is fixed in the mounting groove of the sign bracket and embedded in the support hole of the decorative bracket.

[0013] In the above scheme, the support hole is a stepped hole, and the cover plate is inserted into the stepped hole to achieve fixation and support.

[0014] In the above scheme, the sign bracket and the decorative bracket are fixedly connected by at least one of screws and buckles.

[0015] In the above solution, the sign bracket is equipped with clips, positioning holes, and screw holes, while the decorative bracket is equipped with matching clip holes, positioning posts, and screw posts. The sign bracket and the decorative bracket are positioned using the positioning posts and positioning holes, and are fixedly connected using clips-clip holes and screw posts-screw holes.

Detailed Implementation

[0025] To enable those skilled in the art to fully understand the technical solution and beneficial effects of this utility model, the following detailed description is provided in conjunction with specific embodiments and accompanying drawings. It should be emphasized that these embodiments and drawings are merely some implementations of this utility model. Besides these, this utility model can have many other implementations, and any simple improvements or substitutions based on these implementations will fall within the protection scope of this utility model.

[0026] like Figure 1-7 The illustrated touch-sensitive vehicle light marking installation and fixing structure mainly includes a touch PCB 1, a marking cover plate 2, a marking bracket 3, and a decorative bracket 4. The touch PCB 1 is fixed to the back of the marking cover plate 2 using a hot-melt adhesive method, thus forming assembly A. The marking bracket 3 is assembled with the decorative bracket 4 using screws, clips, or other connection methods, thus forming assembly B. Assembly A and assembly B are snapped together to form a complete touch-sensitive vehicle light marking. This touch-sensitive vehicle light marking can be installed and fixed to the front or rear of a vehicle. When the marking cover plate 2 is touched by hand from outside the vehicle, in addition to illuminating the marking, the front or rear trunk can also be unlocked.

[0027] The touch PCB 1 is rectangular, with two positioning holes 5 along its diagonal and symmetrical clearance grooves along its long side. The touch PCB 1 uses a highly sensitive capacitive or resistive touch sensor or module, operating on a principle similar to a mobile phone touchscreen. In addition, an LED light source is also provided on the touch PCB 1. The touch PCB 1 is electrically connected to the car's power supply, front trunk lock, or rear trunk lock via wires, thereby enabling functions such as illuminating indicators upon touch and unlocking the front / rear trunk.

[0028] The sign cover 2 is made of transparent or semi-transparent material, on which the sign pattern is formed. When the PCB 1 is touched, the LED on it lights up, and the light passes through the sign cover 2 to create a sign lighting effect. The sign cover 2 is also rectangular, with two sets of latches 7 with slots symmetrically arranged on its back. Around the latches 7, two (or three or five) hot-melt positioning posts 6 are arranged alternately up and down.

[0029] The sign holder 3 is made of plastic injection molding and includes a base and a rectangular tube protruding from the center of the base. Two snap-fit ​​protrusions 8 are symmetrically arranged on the inner wall of the top of the rectangular tube (e.g., Figure 3 A buckle 7 is also provided on the side of the root of the rectangular tube. In addition, screw holes 10 and positioning holes 5 are symmetrically provided at both ends of the back of the sign bracket 3.

[0030] Decorative bracket 4 is also made of plastic injection molding, and its front shape is similar to that of logo bracket 3. A boss is provided in the middle of decorative bracket 4, and a support hole 13 is provided in the middle of the boss. Clip holes 12 are provided on the side walls of decorative bracket 4, and screw posts 9 and positioning posts 11 (e.g., ...) are symmetrically provided at both ends of the back of decorative bracket 4. Figure 4 (As shown).

[0031] The assembly method for this touch-sensitive vehicle light indicator is as follows: Figure 2 As shown, firstly, the hot-melt positioning post 6 on the label cover 2 is aligned and passes through the positioning hole 5 on the touch PCB 1. Then, heating is applied to melt the hot-melt positioning post 6, thereby fixing the touch PCB 1 and the label cover 2 together to form assembly A. Figure 4 As shown, in the second step, align the positioning post 11 on the decorative bracket 4 with the positioning hole 5 on the sign bracket 3, press them together until the buckle 7 on the sign bracket 3 smoothly engages with the buckle hole 12 on the decorative bracket 4, then insert and tighten the screw to ensure that the sign bracket 3 and the decorative bracket 4 are reliably fixed together, forming assembly B. Finally, align the buckle 7 on the sign cover plate 2 with the mounting groove on the sign bracket 3, and press firmly to make the buckle protrusion 8 on the sign bracket 3 engage with the buckle 7 groove on the sign cover plate 2, thereby fixing assembly A and assembly B together.

[0032] The method of using the touch-sensitive vehicle light indicator is as follows: When the vehicle is unlocked and stationary, a person outside the vehicle touches the indicator cover 2 (similar to a mobile phone screen protector). The touch PCB 1, which is in close contact with the indicator cover 2, lights up the indicator and unlocks the front trunk after sensing the touch. The indicator turns off when the indicator cover 2 is touched again.

[0033] This invention employs a combination of multiple sets of clips, screws, and other fixing structures, along with a combination of positioning posts and positioning holes, to achieve the installation and fixation of touch-sensitive vehicle light markings. This process rationally utilizes the deformation characteristics of materials and the features of the clip structure, ensuring the reliability of the installation and positioning between various parts while maximizing the effective touch area of ​​the touch PCB, ultimately improving touch sensitivity and assembly efficiency.
