Abstract
Description
Technical Field
[0001] This application relates to the field of vehicle component technology, and in particular to a fixed structure, an A-pillar trim assembly, and a vehicle. Background Technology
[0002] Functional components, such as cameras, usually need to be fixed in place by a fixing structure. To facilitate assembly and disassembly, the fixing structure is assembled by snap-fit, which allows for quick positioning of the functional components.
[0003] Existing fixed structures are assembled using snap-fit methods. In practical applications, these fixed structures are subjected to continuous or periodic vibrations, which amplifies the weaknesses of the snap-fit structure. Vibration can cause the snaps to undergo micro-displacement and repeated loosening. Over time, this may reduce the snap-fit depth and friction, making it easier for the snaps to come loose and reducing the reliability of functional components installed on the fixed structure. Utility Model Content
[0004] The purpose of this application is to solve the aforementioned technical problems by providing a fixing structure, an A-pillar trim assembly, and a vehicle, thereby improving the stability of the fixing structure and preventing assembly failure. To achieve the above objective, the technical solution of this application is as follows: In a first aspect, this application provides a fixing structure for mounting a plate. The mounting plate has an opening. The fixing structure includes a housing and a bracket. The bracket is disposed corresponding to the opening and connected to the inner surface of the mounting plate. The housing is disposed on the outer surface of the mounting plate. A snap-fit member is disposed on the housing. The snap-fit member passes through the opening. One side of the snap-fit member abuts against the edge of the opening, and the other side of the snap-fit member abuts against the bracket, so that both sides of the snap-fit member are respectively positioned against the edge of the opening and the bracket along the extension direction of the snap-fit member.
[0005] In a preferred embodiment, the snap-fit component has a first limiting portion, and the inner surface of the mounting plate is provided with a first protrusion at the edge of the opening. The first limiting portion and the first protrusion are arranged opposite to each other along the extension direction of the snap-fit component, and the first limiting portion abuts against the first protrusion.
[0006] In a further technical solution, the snap-fit component has a limiting groove disposed on the inner wall facing the opening, the first limiting part being one wall of the limiting groove, and the other wall of the limiting groove abutting against the outer surface of the mounting plate.
[0007] In a preferred embodiment, the snap-fit component has an installation opening extending through both sides, and the side of the bracket facing away from the mounting plate has a second protrusion that extends into the installation opening and abuts against the inner wall of the installation opening facing away from the mounting plate.
[0008] In a further technical solution, the snap-fit component has a second limiting part on the inner wall of the mounting port away from the mounting plate, and a fixing part extending away from the mounting plate is provided on the second protrusion. The fixing part and the second protrusion are connected to form a clamp, and the clamp abuts against the second limiting part.
[0009] In a further technical solution, the bracket is provided with an opening for avoiding the snap-fit component, and a second protrusion is provided on one side of the opening.
[0010] In a preferred embodiment, the mounting plate is provided with a mounting part, and the bracket is provided with a mating part corresponding to the mounting part, the mating part being connected to the mounting part.
[0011] In a preferred embodiment, the housing is provided with a plurality of fasteners in the circumferential direction, and the bracket is provided with corresponding slots for the fasteners, with the edges of the fasteners abutting against the slots.
[0012] Secondly, this application provides an A-pillar trim assembly, including the aforementioned fixing structure and mounting plate.
[0013] Thirdly, this application provides a vehicle including the aforementioned A-pillar trim assembly.
[0014] Compared with existing technologies, the beneficial effects of this application on the fixed structure, A-pillar trim assembly, and vehicle are mainly reflected in: The two sides of the snap-fit component form limits with the edge of the opening and the bracket, respectively. When the snap-fit component moves outward relative to the mounting plate, the edge of the opening and the bracket exert a reaction force on the snap-fit component in the extension direction of the snap-fit component. This prevents the snap-fit component from coming loose from the opening when it is not subjected to external force after it is installed in place, reduces the risk of deformation failure, maintains the stability of the connection between the housing and the bracket, and thus ensures the reliability of the fixed structure.

[0017] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.
[0018] Example This embodiment provides a fixing structure for mounting a panel 1, which can be a trim panel inside a vehicle. Since a functional component 5 needs to be installed on the trim panel, the functional component 5 is fixed to the trim panel by the fixing structure. The mounting plate 1 has an opening 11 to facilitate the installation of the fixing structure and the functional component 5. For example, the functional component 5 is a camera, with its lens located outside the trim panel, enabling the camera to perform its functions.
[0019] In related technologies, the fixing structure is assembled directly using a snap-fit method. While the fixing structure is simple, under prolonged vibration conditions, the snap-fit points may deform excessively and fail, causing the fixing structure to loosen. This reduces the reliability of the fixing structure and cannot guarantee the normal use of the internally installed functional components 5, increasing the maintenance frequency. Therefore, this embodiment improves the fixing structure to solve the above problems and enhance the assembly reliability and stability of the fixing structure, which will be described in detail below.
[0020] like Figures 1-4 , Figure 7As shown, the fixing structure includes a housing 2 and a bracket 3. The bracket 3 is provided corresponding to the through 11 and is connected to the inner surface of the mounting plate 1. The housing 2 is provided on the outer surface of the mounting plate 1. A snap-fit 4 is provided on the housing 2. The snap-fit 4 is provided through the through 11. One side of the snap-fit 4 abuts against the edge of the through 11, and the other side of the snap-fit 4 abuts against the bracket 3, so that the two sides of the snap-fit 4 are respectively positioned against the edge of the through 11 and the upper limit of the bracket 3 along the extension direction of the snap-fit 4.
[0021] The area of the opening 11 is adapted to the space occupied by the exposed opening 11 of the fixed structure. The housing 2 is an appearance component located outside the mounting plate 1. The circumferential edge of the housing 2 is set to correspond to the opening 11, so as to minimize the gap between the edge of the housing 2 and the opening 11, maintain a good appearance on the mounting plate 1, and ensure the functional requirements of the functional components 5 inside the fixed structure.
[0022] The inner surface of the mounting plate 1 refers to the back of the mounting plate 1. The outer surface of the mounting plate 1 is set opposite to the inner surface, and its outer surface is the appearance surface. The extension direction of the snap-fit 4 refers to the insertion direction of the snap-fit 4 relative to the mounting plate 1 from the outside to the inside.
[0023] Multiple snap-fit pieces 4 can be provided on the housing 2. The two sides of the snap-fit pieces 4 form limits with the edge of the through 11 and the bracket 3 respectively. When the snap-fit pieces 4 move outward relative to the mounting plate 1, the edge of the through 11 and the bracket 3 exert a reaction force on the snap-fit pieces 4 in the extension direction. This prevents the snap-fit pieces 4 from coming loose from the through 11 when they are not subjected to external force after they are installed in place, reducing the risk of deformation failure, maintaining the stability of the connection between the housing 2 and the bracket 3, thereby ensuring the reliability of the fixed structure, reducing the maintenance frequency, and extending the service life of the fixed structure.
[0024] For example, such as Figure 3 As shown, the inner surface of the mounting plate 1 is provided with a first protrusion 12 at the edge of the opening 11, and the snap-fit member 4 has a first limiting part 41. The first limiting part 41 and the first protrusion 12 are arranged opposite to each other along the extension direction of the snap-fit member 4, and the first limiting part 41 abuts against the first protrusion 12.
[0025] The bracket 3 is located on the inner surface of the mounting plate 1 and is hidden on the back of the mounting plate 1. It can be assembled with the housing 2. Compared with the housing 2 being directly installed on the mounting plate 1, it is more stable and facilitates the installation of the functional components 5.
[0026] The first protrusion 12 can be an elongated structure. When the snap-fit 4 is inserted along the opening 11, one side wall of the snap-fit 4 slides from the outside to the inside along the inner wall of the opening 11 until the first limiting part 41 abuts against the first protrusion 12.
[0027] A limiting groove 43 is provided on the snap-fit part 4 behind the first limiting part 41 along the extension direction. The limiting groove 43 faces the inner wall of the opening 11. The first limiting part 41 is one wall of the limiting groove 43. The other wall of the limiting groove 43 abuts against the outer surface of the mounting plate 1. The snap-fit part 4 is more stably positioned in the opening 11 through the limiting groove 43, so that the snap-fit part 4 and the first protrusion 12 fit more tightly, and the snap-fit part 4 is prevented from moving in the extension direction.
[0028] The snap-fit part 4 can be made of plastic and has a certain deformation effect. The snap-fit part 4 can be inserted into the opening 11 by compression and positioned at the edge of the opening 11.
[0029] For example, such as Figure 3 , Figure 4 As shown, the bracket 3 has a second protrusion 31 on the side facing away from the mounting plate 1, and the snap-fit 4 has a mounting opening 42 that extends through both sides of it. The second protrusion 31 extends into the mounting opening 42 and abuts against the inner wall of the mounting opening 42 facing away from the mounting plate 1.
[0030] The through direction of the mounting port 42 intersects with the extension direction. The second protrusion 31 abuts against the inner wall of the mounting port 42 away from the mounting plate 1. When the snap-fit 4 moves in the opposite direction of the extension direction, the second protrusion 31 limits the inner wall of the mounting port 42, and the snap-fit 4 cannot be released from the second protrusion 31, thereby ensuring the stability of the assembly.
[0031] The area of the mounting opening 42 is adapted to the structure of the second protrusion 31, and the second protrusion 31 can extend smoothly into the mounting opening 42, so as to ensure that the second protrusion 31 has a certain effective contact area when it is limited to the inner wall of the mounting opening 42.
[0032] When the snap-fit 4 needs to be removed from the second protrusion 31, a force intersecting the extension direction is applied to the snap-fit 4 to make it exit the mounting port 42, and a force in the opposite direction to the extension direction is applied to the snap-fit 4 to move the snap-fit 4 out of the opening 11.
[0033] The second protrusion 31 can be made of plastic material, which has a certain deformation effect. When the second protrusion 31 is subjected to external force, it can be effectively detached from the mounting port 42 and the snap fastener 4.
[0034] For example, such as Figure 4 As shown, the snap-fit 4 has a second limiting part 44 on the inner wall of the mounting port 42 away from the mounting plate 1. The second protrusion 31 is provided with a fixing part 32 extending away from the mounting plate 1. The fixing part 32 and the second protrusion 31 are connected to form a clamp β. The clamp β abuts against the second limiting part 44, that is, the fixing part 32 abuts against the side opposite to the snap-fit 4.
[0035] The fixing part 32 and the second protrusion 31 can be an integral structure. The clamp β abuts against the edge of the mounting opening 42, and the fixing part 32 abuts against the side opposite to the snap-fit 4. When the snap-fit 4 moves outward relative to the mounting plate 1, the clamp β can stably restrict the edge position of the mounting opening 42, further effectively preventing the snap-fit 4 from loosening from the second protrusion 31.
[0036] For example, such as Figure 3 , Figure 6 As shown, the bracket 3 is provided with an opening 33 for avoiding the snap fastener 4. A second protrusion 31 is provided on one side of the opening 33, and a first protrusion 12 is exposed on the other side of the opening 33.
[0037] The area of the opening 33 is adapted to the space occupied by the snap-fit member 4, allowing the snap-fit member 4 to smoothly pass through the through-hole 11 and the opening 33. A space for positioning the snap-fit member 4 is formed between the second protrusion 31 and the first protrusion 12. The snap-fit member 4 passes through the opening 33 and cooperates with the second protrusion 31. The circumferential fit between the opening 33 and the mounting plate 1 is more compact, which helps to improve the connection strength between the bracket 3 and the mounting plate 1.
[0038] For example, such as Figure 3 , Figure 5 , Figure 6 As shown, the mounting plate 1 is provided with a mounting part 13, and the bracket 3 is provided with a mating part 34 corresponding to the mounting part 13, and the mating part 34 is connected to the mounting part 13. The housing 2 is provided with a plurality of fasteners 21 in the circumferential direction, and the bracket 3 is provided with a corresponding latch 35 for the fasteners 21, and the edges of the fasteners 21 and the latch 35 abut against each other.
[0039] The mounting part 13 protrudes from the inner surface of the mounting plate 1, and the mating part 34 can be a mating hole, into which the mounting part 13 is inserted and fixed. There can be multiple mounting parts 13, and the bracket 3 can be pre-positioned on the mounting plate 1 through multiple mounting parts 13, providing a stable foundation for the subsequent installation of the bracket 3.
[0040] The fastener 21 is inserted into the through opening 11 and engages with the edge of the bayonet 35. While the bracket 3 is pre-positioned with the mounting plate 1, the fastener 21 is used to further strengthen the connection strength between the bracket 3 and the mounting plate 1, ensuring the stability of the connection between the circumferential position of the bracket 3 and the housing 2.
[0041] In addition to the connection between the bracket 3 and the mounting plate 1 via the mounting part 13 and the mating part 34, the bracket 3 can also be connected by other methods such as welding, riveting, and screwing, and this application does not impose any restrictions.
[0042] For example, such as Figure 1 , Figure 2As shown, the housing 2 and the bracket 3 are connected to form a mounting cavity, which is used to install the functional component 5.
[0043] The mounting component 5 can be a camera, with both ends of the camera abutting against the housing 2 and the bracket 3 respectively, ensuring the stability of the camera in the mounting cavity. The housing 2 is provided with a window 22, and the camera lens corresponds to the window 22 to meet the normal field of view requirements of the camera.
[0044] The fixed structure is a component of the A-pillar trim assembly, which also includes the aforementioned mounting plate 1, which is the upper trim panel of the A-pillar.
[0045] The A-pillar trim panel is an integral part of the vehicle, and the benefits of a fixed structure in a vehicle are the same as those mentioned above.
[0046] It should be noted that the above-mentioned vehicles are not limited to automobiles, trains, or other means of transportation; any situation similar to this application is applicable to this application.
[0047] In the description of this application: Unless otherwise stated, "inner" and "outer" refer to the inner and outer contours of the corresponding components themselves.
[0048] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. "Multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0049] Unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0050] Although preferred embodiments of this application have been described, they are not intended to limit the application. It is obvious that those skilled in the art can make various changes and modifications to this application without departing from the inventive concept and scope of this application.
