Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and more specifically to a vehicle. Background Technology

[0002] Vehicles (such as electric or gasoline-powered vehicles) are generally equipped with headlights to provide illumination at night and ensure driving safety. In related technologies, bumpers typically form mounting holes, within which the headlights are installed. A bumper bracket is mounted on the bumper, and the bracket has a locking mechanism. The headlight has a locking hole, and the locking mechanism engages with the locking hole. However, in these technologies, during vehicle operation, the locking mechanism can wobble within the locking hole, potentially causing the engagement to fail and the headlight to detach from the bumper bracket. Utility Model Content

[0003] The purpose of this utility model is to provide a vehicle that solves the problem of the locking part wobbling in the locking hole, causing the locking to fail.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] According to the first aspect of this application, this application provides a vehicle including a headlight, a headlight bracket connected to the headlight, a bumper bracket and a bumper connected to the bumper, and a snap-fit ​​portion, a first limiting portion and a snap-fit ​​hole provided between the bumper bracket and the headlight bracket, the snap-fit ​​portion being snapped into the snap-fit ​​hole, the first limiting portion being provided in the snap-fit ​​hole, and the first limiting portion being used to limit the position of the snap-fit ​​portion in the snap-fit ​​hole.

[0006] With the above configuration, the headlight bracket is connected to the headlight, and the bumper bracket is connected to the bumper. A snap-fit ​​part, a first limiting part, and a snap hole are provided between the bumper bracket and the headlight bracket. The snap-fit ​​part is snapped into the snap hole, and the first limiting part is provided in the snap hole. The first limiting part is used to limit the position of the snap-fit ​​part in the snap hole to prevent the first limiting part from shaking in the snap hole, thereby preventing the snap-fit ​​part from separating from the snap hole and preventing the headlight from detaching from the bumper bracket due to snap-fit ​​failure.

[0007] In one possible implementation, the locking hole is provided on the headlight bracket, and the locking part and the first limiting part are both provided on the bumper bracket.

[0008] Based on the above-mentioned technical means, the locking hole is set on the headlight bracket, and the locking part and the first limiting part are both set on the bumper bracket, which can realize a precise and stable connection between the headlight bracket and the bumper bracket, and play a role in improving assembly efficiency and ensuring connection reliability.

[0009] In one possible implementation, the snap-fit ​​portion includes a snap-fit ​​plate and a snap-fit ​​block, the snap-fit ​​block being disposed at the end of the snap-fit ​​plate, the snap-fit ​​plate passing through a snap-fit ​​hole, and the snap-fit ​​block abutting against the first surface of the headlight bracket away from the bumper bracket.

[0010] According to the above-mentioned technical means, the snap-fit ​​part only needs to be forceped from one side to disengage the snap-fit ​​block from the snap-fit ​​hole, which facilitates the disassembly of the bumper and avoids the snap-fit ​​hook breaking or the bumper bracket separating from the bumper due to excessive disassembly force during the disassembly process.

[0011] In one possible implementation, the locking hole includes a first hole wall and a second hole wall disposed opposite to each other, the locking plate is parallel to the first hole wall, and the first limiting portion is in contact with the first hole wall and the second hole wall.

[0012] According to the above-mentioned technical means, the first limiting part is in contact with the first hole wall and the second hole wall at the same time, which can prevent the locking plate from moving in a direction perpendicular to the first hole wall and the second hole wall, so as to avoid the locking block from detaching from the first surface, that is, to prevent the locking block from detaching from the locking hole.

[0013] In one possible implementation, the card block has a snap-fit ​​surface that contacts the first surface, and the angle between the snap-fit ​​surface and the first surface is 20°-40°.

[0014] According to the above technical means, the snap-fit ​​surface is inclined relative to the first surface, so that the snap-fit ​​structure automatically locks when subjected to force, thereby improving the connection stability; at the same time, there is an angle between the snap-fit ​​surface and the first surface, which also facilitates the disassembly of the bumper bracket and the headlight bracket.

[0015] In one possible implementation, there is a detachable connection between the headlight bracket and the headlight.

[0016] Based on the above technical means, the headlight bracket and the headlight body are fixed with screws to ensure long-term reliable connection and reduce safety hazards caused by connection failure.

[0017] In one possible implementation, the vehicle further includes a first connecting bolt, a first limiting hole and a first connecting hole on the headlight bracket, a second limiting part and a first threaded hole on the headlight, the second limiting part being disposed in the first limiting hole so that the first connecting hole is aligned with the first threaded hole, and the first connecting bolt passing through the first connecting hole and engaging with the first threaded hole.

[0018] According to the above technical means, the first limiting hole of the headlight bracket and the second limiting part of the headlight form a pre-positioning structure. During assembly, the second limiting part is inserted into the first limiting hole, forcibly constraining the headlight in the radial or circumferential position, ensuring that the first connecting hole of the headlight and the bracket are completely aligned with the first threaded hole, avoiding the problem of "blindly aligning holes" when using pure bolt connections, and improving the success rate of assembly in one go.

[0019] In one possible implementation, the bumper bracket is welded to the inner surface of the bumper.

[0020] Based on the above technical means, welding can be completed directly on the inner surface of the bumper, and the bracket can be designed to fit closely to the inner surface, eliminating the need to reserve space for bolt operation (such as the wrench movement area), making the overall structure of the bumper more compact.

[0021] In one possible implementation, a third limiting part is provided on the inner surface, which is used to limit the position of the bumper bracket.

[0022] Based on the above-mentioned technical means, the third limiting part can accurately position the bumper bracket through physical contact before welding, ensuring that the gap between the bumper bracket and the bumper is uniform and the welding area is accurately aligned, eliminating the positional deviation that may occur during manual assembly and improving the product assembly accuracy.

[0023] In one possible implementation, the third limiting part includes a first limiting block and a second limiting block, both of which abut against the bumper bracket. The first limiting block is used to limit the position of the bumper bracket along a first direction, and the second limiting block is used to limit the position of the bumper bracket along a second direction. There is an included angle between the first direction and the second direction.

[0024] Based on the above technical means, by using bidirectional limiting and directional constraints, assembly errors in each direction are reduced from the source, thus preventing positional displacement of the bumper bracket.

[0025] The beneficial effects of this utility model are:

[0026] (1) In the first aspect, the bumper bracket and the headlight bracket of this application are provided with a snap-fit ​​part, a first limiting part and a snap-fit ​​hole. The snap-fit ​​part is snapped into the snap-fit ​​hole and the first limiting part is provided in the snap-fit ​​hole. The first limiting part is used to limit the position of the snap-fit ​​part in the snap-fit ​​hole, so as to solve the problem that the snap-fit ​​part shakes in the snap-fit ​​hole, causing the snap-fit ​​to fail.

[0027] (2) Secondly, the first limiting hole of the headlight bracket and the second limiting part of the headlight form a pre-positioning structure. During assembly, the second limiting part is inserted into the first limiting hole to forcibly constrain the headlight in the radial or circumferential position, thereby improving the assembly success rate.

[0028] It should be noted that the technical effects of the second implementation method can be found in the technical effects of the corresponding implementation method in the first aspect, and will not be repeated here.

[0029] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit this application. Attached Figure Description

Detailed Implementation

[0040] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0041] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0042] This application provides a vehicle. The specific type of vehicle is not specifically limited in this application; for example, the vehicle provided in this application can be an electric vehicle, a hybrid vehicle, a gasoline vehicle, or a solar-powered vehicle. It is understood that an electric vehicle is powered by an electric motor and also has a battery connected to the motor to supply power; a hybrid vehicle may include a gasoline engine and an electric motor, which can simultaneously or alternately power the vehicle; a gasoline vehicle includes a gasoline engine and a transmission, with the gasoline engine providing power to the vehicle through the transmission; and a solar-powered vehicle utilizes solar energy to generate electricity, which is then used to power the vehicle via an electric motor.

[0043] The vehicle provided in this application embodiment can also be a vehicle of different types. For example, the vehicle provided in this application embodiment can be a sedan, a sport utility vehicle (SUV), or a multi-purpose vehicle (MPV), etc.

[0044] In some embodiments, see Figure 1 The vehicle in this application includes a vehicle body, a bumper 103, and headlights 100. The vehicle body encloses a driver's cab and a passenger cabin, with the driver and co-driver located in the driver's cab and other passengers in the passenger cabin. The bumper 103 is located at the front end of the vehicle body and can be connected to the vehicle body by bolts and / or clips. The bumper 103 can form mounting holes, and the headlights 100 are installed in the mounting holes. When the light is dim, the headlights 100 are turned on to improve driving safety.

[0045] Please refer to Figure 2 and Figure 3In this embodiment, the vehicle also includes a headlight bracket 101 and a bumper bracket 102. The headlight bracket 101 can be disposed on the inner side of the bumper 103 and is connected to the headlight 100. For example, the headlight bracket 101 can be connected to the headlight 100 by means of snap-fit ​​or bolt connection. The bumper bracket 102 is disposed between the headlight bracket 101 and the inner wall of the bumper 103 and is connected to both the bumper 103 and the headlight bracket 101, so that the connection between the headlight 100 and the bumper 103 can be realized through the bumper bracket 102 and the headlight bracket 101.

[0046] The bumper bracket 102 and the headlight bracket 101 are provided with a snap-fit ​​part 104, a first limiting part 105, and a snap-fit ​​hole 106. The snap-fit ​​part 104 is snapped into the snap-fit ​​hole 106, and the first limiting part 105 is disposed in the snap-fit ​​hole 106. The first limiting part 105 is used to limit the position of the snap-fit ​​part 104 in the snap-fit ​​hole 106. That is, both the snap-fit ​​part 104 and the first limiting part 105 are located in the snap-fit ​​hole 106, and the first limiting part 105 is used to prevent the snap-fit ​​part 104 from shaking in the snap-fit ​​hole 106 to prevent the snap-fit ​​part 104 from separating from the snap-fit ​​hole 106.

[0047] For example, the bumper bracket 102 is a one-piece injection molded plastic bracket, which can be made of PP (Polypropylene) material, and the main wall thickness of the part is 2.0mm-2.5mm; the headlight bracket 101 is a one-piece injection molded plastic bracket, which can be made of PP (Polypropylene) reinforced with glass fiber or PA6 (Polyamide 6) reinforced with glass fiber.

[0048] In some embodiments, see Figure 2 and combined Figure 3 The locking hole 106 is disposed on the headlight bracket 101, and the locking portion 104 and the first limiting portion 105 are both disposed on the bumper bracket 102. Of course, in other embodiments, the locking hole 106 can be disposed on the bumper bracket 102, and correspondingly, the locking portion 104 and the first limiting portion 105 are both disposed on the headlight bracket 101. This embodiment will be described using the example where the locking hole 106 is disposed on the headlight bracket 101, and the locking portion 104 and the first limiting portion 105 are both disposed on the bumper bracket 102.

[0049] In the above implementation, the cooperation between the snap-fit ​​part 104 and the first limiting part 105 enables a precise and stable connection between the headlight bracket 101 and the bumper bracket 102, which plays a role in improving assembly efficiency and ensuring connection reliability.

[0050] In some embodiments, see Figure 3 The snap-fit ​​part 104 includes a snap-fit ​​plate 401 and a snap-fit ​​block 402. The snap-fit ​​block 402 is disposed at the end of the snap-fit ​​plate 401. The snap-fit ​​plate 401 passes through the snap-fit ​​hole 106. The snap-fit ​​block 402 abuts against the first surface 41 of the headlight bracket 101 away from the bumper bracket 102 to achieve snap-fit.

[0051] In the above implementation, the snap-fit ​​plate 401 and the snap-fit ​​block 402 are roughly designed with a "7" shaped barb. The snap-fit ​​block 402 abuts against the first surface 41 of the headlight bracket 101 away from the bumper bracket 102. When the snap-fit ​​plate 401 passes through the snap hole 106, the snap-fit ​​block 402 and the first surface 41 of the headlight bracket form a firm fastening structure. At the same time, the snap-fit ​​part 104 is set as a single-sided snap-fit. Only one side needs to be applied to force so that the snap-fit ​​block can be disengaged from the snap hole, which facilitates the disassembly of the bumper 103 and avoids the snap-fit ​​hook breaking due to excessive disassembly force during the disassembly process, or the bumper bracket 102 separating from the bumper 103.

[0052] In some embodiments, see Figure 3 The card hole 106 includes a first hole wall 601 and a second hole wall 602 disposed opposite to each other. The card plate 401 is parallel to and in contact with the second hole wall 602. The card block 402 abuts against the first surface 41 of the edge of the second hole wall 602. The first limiting part 105 is in contact with the first hole wall 601 and the second hole wall 602.

[0053] In the above implementation, the first limiting part 105 contacts the first hole wall 601 and the second hole wall 602 at the same time, which can prevent the snap-fit ​​plate from moving in a direction perpendicular to the first hole wall and the second hole wall, so as to avoid the snap-fit ​​block from detaching from the first surface, that is, to prevent the snap-fit ​​block from detaching from the snap-fit ​​hole.

[0054] In some embodiments, see Figure 3 The latch 402 has a latching surface 42 that contacts the first surface 41, and the angle between the latching surface 42 and the first surface 41 is 20°-40°. For example, the angle between the latching surface 42 and the first surface 41 is about 30°, and the latching overlap is about 2mm.

[0055] With the above settings, the snap-fit ​​surface 42 is inclined relative to the first surface, so that the snap-fit ​​structure automatically locks when subjected to force, thereby improving the connection stability; at the same time, there is an angle between the snap-fit ​​surface 42 and the first surface 41, which also facilitates the disassembly of the bumper bracket 102 and the headlight bracket 101.

[0056] The vehicle provided in this application embodiment has a headlight bracket 101 connected to a headlight 100, and a bumper bracket 102 connected to a bumper 103. A snap-fit ​​part 104, a first limiting part 105, and a snap hole 106 are provided between the bumper bracket 102 and the headlight bracket 101. The snap-fit ​​part 104 is snapped into the snap hole 106, and the first limiting part 105 is disposed in the snap hole 106. The first limiting part 105 is used to limit the position of the snap-fit ​​part 104 in the snap hole 106 to prevent the first limiting part 105 from shaking in the snap hole 106, thereby preventing the snap-fit ​​part 104 from separating from the snap hole 106 and preventing the headlight from detaching from the bumper bracket due to snap-fit ​​failure.

[0057] In some embodiments, see Figure 4 and combined Figure 5 The headlight bracket 101 and the headlight 100 are detachably connected.

[0058] In the above implementation, the headlight bracket 101 is designed with a first fixing surface 1001 and a second fixing surface 1004. The headlight bracket 101 and the headlight body 100 are fixed with screws to ensure long-term reliable connection and reduce safety hazards caused by connection failure.

[0059] For example, screws of the corresponding specifications can be selected according to the materials of the headlight and headlight bracket to adapt to different strength requirements, which is highly flexible.

[0060] In some embodiments, see Figure 6 and combined Figure 4 The vehicle also includes a first connecting bolt 107, a first limiting hole 10 and a first connecting hole 11 on the headlight bracket 101, a second limiting part 12 and a first threaded hole 13 on the headlight 100, the second limiting part 12 is disposed in the first limiting hole 10 so that the first connecting hole 11 is aligned with the first threaded hole 13, and the first connecting bolt 107 passes through the first connecting hole 11 and engages with the first threaded hole 13.

[0061] In the above implementation, the first limiting hole 10 of the headlight bracket 101 and the second limiting part 12 of the headlight 100 form a pre-positioning structure. During assembly, the second limiting part 12 is inserted into the first limiting hole 10, forcibly constraining the headlight in the radial or circumferential position, ensuring that the first connecting hole 11 of the headlight and the bracket are completely aligned with the first threaded hole 13, avoiding the problem of "blindly aligning holes" in pure bolt connections, and improving the success rate of assembly in one attempt.

[0062] In some embodiments, see Figure 7 The inner surfaces of the bumper bracket 102 and the bumper 103 are welded together.

[0063] In the above implementation, the bumper bracket 102 and the bumper 103 are fixed together by welding. The inner surfaces of the bumper bracket 102 and the bumper 103 are welded together. The thickness of the bumper bracket in the welding area does not exceed 2.0mm, and the welding area is 25mm x 35mm or more. To ensure the welding strength, welding areas need to be arranged on both sides of the snap-fit ​​point.

[0064] In some embodiments, see Figure 7 A third limiting part 108 is provided on the inner surface, which is used to limit the position of the bumper bracket 102.

[0065] In the above implementation, the third limiting part 108 can accurately position the bumper bracket 102 through physical contact before welding, ensuring that the gap between the bumper bracket 102 and the bumper 103 is uniform and the welding area is accurately aligned, eliminating possible positional deviations during manual assembly and improving product assembly accuracy.

[0066] In some embodiments, see Figure 7 The third limiting part 108 includes a first limiting block 81 and a second limiting block 82. Both the first limiting block 81 and the second limiting block 82 abut against the bumper bracket 102. The first limiting block 81 is used to limit the position of the bumper bracket 102 along the first direction X, and the second limiting block 82 is used to limit the position of the bumper bracket 102 along the second direction Y. There is an included angle between the first direction X and the second direction Y.

[0067] In the above implementation, the first limiting block 81 is used to limit the position of the bumper bracket 102 along the first direction X, where the first direction X is the horizontal direction, and the second limiting block 82 is used to limit the position of the bumper bracket 102 along the second direction Y, where the second direction Y is the direction perpendicular to the horizontal plane. The bidirectional limiting reduces the assembly error in each direction from the source by constraining the directions, and avoids the bumper bracket 102 from shifting its position.

[0068] For example, the angle between the first direction X and the second direction Y is 70°-110° (e.g., 70°, 90°, 110°, etc.).

[0069] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
