Description

Technical Field

[0001] This utility model relates to the technical field of automotive parts installation, and in particular to a snap-fit ​​assembly, a frame, and a vehicle. Background Technology

[0002] Vehicles typically contain multiple components. To prevent these components from shaking or wobbling during operation and to ensure the normal functioning of the equipment, they need to be fixedly mounted on the vehicle body. However, directly mounting components on the vehicle body can easily cause deformation at the connection points. Therefore, clips are usually used to secure the components.

[0003] To prevent the existing clips from moving relative to the vehicle body during installation, multiple through holes need to be made on the vehicle body to limit the clips from multiple directions, which requires a large number of holes. Utility Model Content

[0004] To solve the technical problem of needing to open multiple through holes in the vehicle body to limit the movement of parts, this utility model provides a buckle assembly, a frame, and a vehicle.

[0005] To achieve the above objectives, the snap-fit ​​assembly is used to connect to the body sheet metal. The snap-fit ​​assembly includes a base and a snap-fit ​​structure. A through hole is provided on the body sheet metal. The snap-fit ​​structure includes a limiting part and a snap-fit ​​part. The limiting part is connected to the base and inserted into the through hole. The snap-fit ​​part is connected to the limiting part and snaps into the inner wall of the through hole. The limiting part has a limiting surface along its circumferential outer wall. The shape of the circumferential outer wall of the limiting surface is adapted to the shape of the inner circumferential surface of the through hole.

[0006] Furthermore, the snap-fit ​​portion has a snap-fit ​​inclined surface on the side facing the inner wall of the through hole, and the snap-fit ​​inclined surface extends obliquely from the limiting portion toward the base.

[0007] Furthermore, the snap-fit ​​structure has an installation opening on its circumferential sidewall, the installation opening extends to the base, the snap-fit ​​part is disposed in the installation opening, and there is a gap between the snap-fit ​​part and the base.

[0008] Furthermore, the limiting part includes a guide part and a fixing part. One end of the fixing part is connected to the base, and the other end is connected to the guide part. The mounting port is opened on the fixing part, and the radial cross-section of the guide part is smaller than the radial cross-section of the fixing part.

[0009] Furthermore, the radial cross-section of the guide portion gradually decreases along the axial direction away from the base.

[0010] Furthermore, it also includes a limiting structure, which is disposed on the base along the circumference of the snap-fit ​​structure, and there is an axial gap between the snap-fit ​​portion and the limiting structure.

[0011] Furthermore, the base is provided with a mounting part for mounting parts, and the mounting part and the limiting part are respectively provided on opposite sides of the base or the mounting part passes through the base.

[0012] Furthermore, it also includes fasteners, which are disposed on the part, connected to the mounting portion, and drive the base to move toward the body sheet metal.

[0013] Another objective of this embodiment is to provide a vehicle frame having the aforementioned snap-fit ​​assembly.

[0014] Another object of this embodiment is to provide a vehicle that is provided with the above-described snap-fit ​​assembly or frame.

[0015] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art:

[0016] (1) Compared with the prior art, the buckle assembly of this utility model has the following characteristics: when in use, the base is connected to the part, the buckling structure is inserted into the through hole on the body sheet metal, the limiting part in the buckling structure extends into the through hole, and a limiting surface is provided on the side wall of the limiting part along the circumferential direction. The limiting surface abuts against the inner wall of the through hole along the circumferential direction. Therefore, the limiting surface can restrict the limiting part from rotating in the circumferential direction in the through hole, thereby realizing the buckle's circumferential limitation. The buckling part is engaged with the inner wall of the through hole, which can restrict the buckle from moving axially in the through hole, thereby realizing the buckle assembly and the body sheet metal's limitation in multiple directions. The part is connected to the base, and the buckle assembly can be installed and limited through a through hole in the body sheet metal, thereby realizing the limited installation of the part on the body sheet metal.

[0017] (2) A snap-fit ​​inclined surface is provided on the side of the snap-fit ​​part facing the inner wall of the through hole. It extends from the limiting part to the base and is inclined radially outward of the limiting part. When the limiting part is inserted into the through hole, the snap-fit ​​inclined surface abuts against the inner wall of the through hole. As the limiting part gradually extends into the through hole, the snap-fit ​​inclined surface fits more tightly against the inner wall of the through hole. When the part is fixed on the base, the part pushes the base to move towards the body sheet metal, which further ensures the snap-fit ​​effect between the snap-fit ​​structure and the through hole and realizes the limiting of the snap-fit ​​assembly and the part on the body sheet metal.

[0031] Example 1

[0032] The present invention provides a snap-fit ​​assembly, referring to... Figures 1-5 The body sheet metal 1 is connected via a snap-fit ​​assembly. In this embodiment, the installation position of the snap-fit ​​assembly inside the vehicle is not limited. For example, the installation position can be located at the body sheet metal in the front compartment, the body sheet metal in the rear compartment, the body sheet metal in the roof, etc. The snap-fit ​​assembly includes a base 3 and a snap-fit ​​structure 4. A through hole 11 is provided on the body sheet metal 1. The base 3 connects the part 2 and the snap-fit ​​structure 4. The part 2 can be a wire harness fixing component, a decorative strip, etc. The part 2 is fixed to the body sheet metal 1 by the snap-fit ​​assembly. In this embodiment, the snap-fit ​​structure 4 and the part 2 are located on opposite sides of the base 3. The snap-fit ​​structure 4 is inserted into the through hole 11, so that the snap-fit ​​assembly is fixed to the body sheet metal 1. The part 2 is fixedly installed with the base 3. After the snap-fit ​​assembly is fixedly installed with the body sheet metal 1, the limited installation of the part 2 can be achieved.

[0033] Reference Figure 2 The snap-fit ​​structure 4 includes a limiting part 41 and a snap-fit ​​part 42. One end of the limiting part 41 is connected to the base 3, and the other end extends into the through hole 11. The limiting surface 43 is disposed on the outer wall of the limiting part 41 along the circumferential direction. In the embodiment, the limiting part 41 is a cylindrical structure, and one or more limiting surfaces 43 may be provided. Preferably, the limiting surface 43 extends along the axial direction of the limiting part 41 to both ends of the limiting part 41. The shape of the outer wall of the limiting surface 43 is adapted to the shape of the inner circumferential surface of the through hole 11. When the limiting part 41 rotates in the through hole 11, the limiting surface 43 abuts against the inner circumferential surface of the through hole 11 along the circumferential direction. Therefore, it can prevent the limiting part 41 from rotating in the circumferential direction in the through hole 11, thereby realizing the circumferential positioning of the snap-fit ​​assembly and the body sheet metal 1, and thus realizing the circumferential positioning of the part 2; the snap-fit ​​part 42 and the inner circumferential surface of the through hole 11 In this embodiment, the snap-fit ​​part 42 protrudes from the outer wall of the limiting part 41 along the circumferential direction. When the limiting part 41 extends into the through hole 11, the snap-fit ​​part 41 snaps into the through hole 11, thereby limiting the snap-fit ​​assembly and the body sheet metal 1 along the axial direction, and thus limiting the part 2 in the axial direction. In this embodiment, by opening a through hole 11 on the body sheet metal 1, the snap-fit ​​part 42 and the limiting surface 43 in the snap-fit ​​structure 4 are used to limit the snap-fit ​​assembly and the body sheet metal 1 along the circumferential and axial directions, thereby limiting the part 2 and the body sheet metal 1 in multiple directions. The snap-fit ​​assembly and the body sheet metal 1 can be limited in multiple directions with only one through hole 11. The part 2 is fixedly installed on the body sheet metal 1, so only one mounting point needs to be provided on the body sheet metal 1 to achieve the positioning of the part 2.

[0034] It should be noted that the radial cross-sectional shape of the limiting part 41 with the limiting surface 43 can be a polygon, such as a triangle, quadrilateral, pentagon, hexagon, etc. In order to achieve the circumferential contact between the limiting surface 43 and the inner wall of the through hole 11, the radial cross-sectional shape of the through hole 11 can be set to a triangle, quadrilateral, pentagon, hexagon, etc. that matches the limiting part 41. The limiting surface 43 abuts against multiple sides and corners of the polygon in the through hole 11 to restrict the rotation of the snap-fit ​​structure 4 in the through hole 11. The radial cross-sectional shape of the limiting part 41 with the limiting surface 43 can also be an irregular shape, which is not limited here.

[0035] In one embodiment, refer to Figure 4 The snap-fit ​​part 42 has a snap-fit ​​inclined surface 421 on the side facing the inner wall of the through hole 11. The snap-fit ​​inclined surface 421 extends inclinedly from the limiting part 41 toward the base 3.

[0036] Specifically, the engaging part 42 is disposed on the outer wall of the limiting part 41 along the circumferential direction. The engaging part 42 has an engaging inclined surface 421 on the side facing the inner wall of the through hole 11. The engaging inclined surface 421 extends obliquely from the limiting part 41 towards the base 3. When the engaging part 42 is inserted into the through hole 11, the engaging inclined surface 421 abuts against the inner wall of the through hole 11, realizing the engaging between the engaging part 42 and the through hole 11. In this embodiment, the end of the engaging inclined surface 421 connected to the limiting part 41 can be flush with the outer wall surface of the limiting part 41 along the circumferential direction. The engaging inclined surface 421 extends obliquely from the limiting part 41 towards the base 3. Since the engaging inclined surface 421 is an inclined surface, the end of the engaging inclined surface 421 near the base 3 is radially outwardly inclined along the limiting part 41. When the limiting part 41 extends into the through hole 11, the engaging inclined surface... One end of 421 connected to the limiting part 41 first extends into the through hole 11. As the limiting part 41 continues to extend, the base 3 gradually approaches the body sheet metal 1. The snap-fit ​​inclined surface 421 tilts outward toward the base 3 along the radial direction of the limiting part 41. Therefore, the snap-fit ​​inclined surface 421 and the inner wall of the through hole 11 gradually come into contact until the force of the snap-fit ​​inclined surface 421 and the inner wall of the through hole 11 abutting against each other can snap the buckle assembly into the through hole 11, thereby realizing the snap-fit ​​fixation between the buckle assembly and the body sheet metal 1. Moreover, this fixing method only requires the abutting cooperation between the through hole 11 and the snap-fit ​​inclined surface 421, without the need to set multiple through hole structures. In the embodiment, the snap-fit ​​part 42 can have a certain elasticity, so the fixed connection between the snap-fit ​​part 42 and the through hole 11 will not cause deformation of the surface of the body sheet metal 1.

[0037] In one embodiment, refer to Figure 2 and Figure 4 The snap-fit ​​structure 4 has an installation opening 44 on its circumferential side wall. The snap-fit ​​part 42 is disposed in the installation opening 44. The installation opening 44 extends to the base 3. The snap-fit ​​part 42 is disposed in the installation opening 44. There is a gap between the snap-fit ​​part 42 and the base 3.

[0038] Specifically, the snap-fit ​​part 42 is disposed in the mounting opening 44 opened on the side wall of the snap-fit ​​structure 4. The mounting opening 44 provides mounting space for the snap-fit ​​part 42 and extends to the base 3. The snap-fit ​​part 42 is disposed in the mounting opening 44 and there is a gap between the snap-fit ​​part 42 and the base 3. Since the snap-fit ​​part 42 has a certain elasticity, when the snap-fit ​​part 42 abuts against the inner wall of the through hole 11, a pressing force is generated on the snap-fit ​​part 42, which causes the snap-fit ​​part 42 to deform or collapse. The gap between the snap-fit ​​part 42 and the base 3 provides space for the deformation or collapse of the snap-fit ​​part 42.

[0039] In one embodiment, refer to Figure 4 The limiting part 41 includes a guide part 411 and a fixing part 412. One end of the fixing part 412 is connected to the base 3, and the other end is connected to the guide part 411. The mounting port 44 is opened on the fixing part 412. The radial cross section of the guide part 411 is smaller than the radial cross section of the fixing part 412.

[0040] Specifically, one end of the fixing part 412 is connected to the base 3, the guide part 411 is provided at the other end of the fixing part 412, the mounting port 44 is opened on the fixing part 412, the snap-fit ​​part 42 is provided in the mounting port 44, the limiting part 41 extends into the through hole 11 of the fixing part 412, and the snap-fit ​​part 42 is snapped and fixed with the through hole 11. The guide part 411 is provided at the other end of the fixing part 412, that is, when the limiting part 41 extends into the through hole 11, the guide part 411 extends into the through hole 11 first. The radial section of the guide part 411 is the plane where the diameter of the guide part 411 is located and the coincidence surface of the guide part 411 column. The radial section of the fixing part 412 is the plane where the diameter of the fixing part 412 is located and the coincidence surface of the fixing part 412 column. The guide part 411 and the fixing part 412 are coaxially arranged. The radial section of the guide part 411 is small, which makes it easy for the limiting part 41 to extend into the through hole 11.

[0041] In one embodiment, refer to Figure 2 and Figure 4 The radial cross section of the guide part 411 gradually decreases along the axis away from the base 3.

[0042] Specifically, the radial cross section of the guide part 411 is smallest at the end opposite to the base 3 along the axis. When installing the buckle and the body sheet metal 1, the end of the guide part 411 opposite to the base 3 along the axis first extends into the through hole 11. The outer wall of the guide part 411 is an inclined surface that gradually extends in the direction opposite to the base 3. The inclined surface of the guide part 411 contacts the inner wall of the through hole 11. As the guide part 411 gradually extends into the through hole 11, the movement of the guide part 411 guides the snap-fit ​​part 42 to extend into the through hole 11.

[0043] In one embodiment, refer to Figures 2-4 The snap-fit ​​assembly also includes a limiting structure 5, which is arranged on the base 3 along the circumference of the snap-fit ​​structure 4, and there is an axial gap between the snap-fit ​​part 42 and the limiting structure 5.

[0044] Specifically, the limiting structure 5 is arranged circumferentially along the snap-fit ​​structure 4, which can improve the structural strength of the limiting part 41 circumferentially. The limiting part 41 extends into the through hole 11 until the limiting structure 5 abuts against the body sheet metal 1. The limiting structure 5 provides a contact surface for the connection between the snap-fit ​​and the body sheet metal 1. Preferably, there are multiple limiting structures 5, which are at least arranged on both sides of the limiting part 41 to ensure the uniform distribution of force between the base 3 and the body sheet metal 1 and to avoid deformation. When the snap-fit ​​structure 4 extends into the through hole 11, the snap-fit ​​structure 4 moves in the through hole 11 along the axial direction until the body sheet metal 1 abuts against the limiting structure 5. Since the snap-fit ​​part 42 is located on the limiting part 41, there is an axial gap between the snap-fit ​​part 42 and the limiting structure 5. Therefore, when the body sheet metal 1 and the limiting structure 5 abut against each other, the snap-fit ​​part 42 can be fully inserted into the through hole 11, ensuring the stability of the connection between the buckle and the body sheet metal 1. It should be noted that a fixing groove is provided around the inner wall of the through hole 11. When the snap-fit ​​part 42 is fully inserted into the through hole 11, the snap-fit ​​part 42 can be snapped into the fixing groove, so that the body sheet metal 1 is limited between the limiting structure 5 and the snap-fit ​​part 42, preventing the snap-fit ​​structure 4 from coming out of the through hole 11.

[0045] In one embodiment, refer to Figure 2 and Figure 3 The base 3 is provided with a mounting part 31 for mounting part 2. The mounting part 31 and the limiting part 41 are located on opposite sides of the base 3 or the mounting part 31 passes through the base 3.

[0046] Specifically, the mounting part 31 can be configured as a mounting hole, through which the part 2 and the base 3 are installed. In the embodiment, during installation, the side wall of the part 2 abuts against the side wall of the base 3, and the mounting part 31 and the limiting part 41 are disposed on two opposite side walls of the base 3. Therefore, when the part 2 is connected to the mounting part 31 and the snap-fit ​​assembly is connected to the body sheet metal 1, the part 2 and the body sheet metal 1 can be disposed on opposite sides of the snap-fit ​​assembly, which facilitates the installation of the snap-fit ​​assembly and the part 2. In the embodiment, the mounting part 31 can also be disposed through the base 3. In this case, the part 2 and the body sheet metal 1 can also be disposed on opposite sides of the snap-fit ​​assembly. It should be noted that multiple mounting parts 31 can be provided to facilitate the limiting of the part 2 and the snap-fit ​​assembly in multiple directions, ensuring the precise limiting of the part 2 and the snap-fit ​​assembly.

[0047] In one embodiment, refer to Figure 5 The snap-fit ​​assembly also includes a fastener 6, which is disposed on part 2. The fastener 6 is connected to the mounting part 31 and drives part 2 to move toward the body sheet metal 1.

[0048] Specifically, the snap-fit ​​assembly also includes a fastener 6, which is disposed on the side wall of part 2 near base 3. In the embodiment, the fastener 6 can be a bolt and nut assembly. In this case, the inner wall of the mounting hole 31 is provided with a thread that mates with the bolt. When part 2 is installed on the snap-fit ​​using the fastener 6, the part 2 is driven to move axially by rotating the bolt, pressing part 2 against the side wall of base 3. The fastener 6 drives part 2 to move toward the body sheet metal 1. Since part 2 and body sheet metal 1 are disposed on opposite sides of base 3, the fastener 6 simultaneously applies pressure to base 3 to move toward body sheet metal 1, further pushing snap-fit ​​structure 4 into through hole 11, ensuring the limiting effect of snap-fit ​​assembly and body sheet metal 1.

[0049] The working principle of the buckle assembly proposed in this embodiment is as follows: A through hole 11 is opened on the body sheet metal 1, and the snap-fit ​​structure 4 of the buckle assembly extends into the through hole 11. The limiting surface 43 of the limiting part 41, which is arranged circumferentially, abuts against the inner circumferential surface of the through hole 11 in the circumferential direction, preventing the buckle assembly from rotating in the through hole 11 and realizing the circumferential limitation of the buckle assembly. A snap-fit ​​part 42 is also provided on the circumferential side wall of the snap-fit ​​structure 4. The snap-fit ​​part 42 extends into the through hole 11, and the side of the snap-fit ​​part 42 facing the inner wall of the through hole 11 is provided with a snap-fit ​​inclined surface 421. The inclined surface 421 slopes outward from the limiting part 41 toward the base 3 along the radial direction of the limiting part 41. When the engaging part 42 penetrates into the through hole 11, the end of the engaging inclined surface 421 connected to the limiting part 41 first enters the through hole 11. As the engaging part 42 extends into the through hole 11, the engaging inclined surface 421 gradually comes into close contact with the inner wall of the through hole 11, thereby realizing the engagement of the engaging structure 4 with the through hole 11. After the engaging structure 4 is inserted into the through hole 11, the part 2 is installed on the base 3. The part 2 is driven to move along the body sheet metal 1 by the fastener 6. The part 2 and the body sheet metal 1 are engaged. Connected to opposite sides of the base 3, the fastener 6 can also move the base 3 toward the body sheet metal, thereby causing the snap-fit ​​structure 4 to extend further into the through hole 11 until the limiting structure 5 on the base 3 abuts against the body sheet metal 1. Since there is an axial gap between the snap-fit ​​part 42 and the limiting structure 5, when the limiting structure 5 abuts against the body sheet metal 1, it can ensure that the snap-fit ​​part 42 is fully inserted into the through hole 11, further ensuring the snap-fit ​​effect of the snap-fit ​​assembly and improving the stability of the snap-fit. The snap-fit ​​assembly of this utility model only needs to be installed on the body sheet metal. A through hole 11 is opened on the body sheet 1, and the snap-fit ​​assembly is inserted into the through hole 11 to complete the limiting of the snap-fit ​​assembly and the body sheet 1 in multiple directions along the axial and circumferential directions. The part 2 is installed on the snap-fit ​​assembly. In order to ensure the precise limiting of the part 2 and the snap-fit ​​assembly, multiple mounting parts 31 can be set to achieve the limiting of the part 2 and the body sheet 1 in multiple directions. The through hole 11 is the mounting point opened on the body sheet 1. The snap-fit ​​assembly of this utility model only needs to open one mounting point on the body sheet 1 to realize the position limiting and installation of the part 2.

[0050] Example 2

[0051] Unlike the above embodiments, this embodiment provides a frame that is equipped with the above-mentioned buckle assembly. The buckle assembly in this embodiment is exactly the same as the buckle assembly described above, and will not be described again in this embodiment.

[0052] Since the frame includes body sheet metal 1, buckle assembly and part 2, the buckle assembly itself connects to achieve the limiting and installation between part 2 and body sheet metal 1. Only one through hole 11 needs to be opened on body sheet metal 1 as the installation point to achieve the limiting installation of part 2. The installation process is simple and facilitates the installation of part 2.

[0053] Example 3

[0054] Unlike the above embodiments, this embodiment provides a vehicle equipped with the above-mentioned buckle assembly or frame. The buckle assembly or frame in this embodiment is exactly the same as the above-mentioned buckle assembly or frame, and will not be described again in this embodiment regarding the buckle assembly.

[0055] Since the vehicle includes a body sheet metal 1, a buckle assembly and a part 2, the part 2 is positioned and installed between the body sheet metal 1 through the connection of the buckle assembly itself. Only one through hole 11 needs to be opened on the body sheet metal 1 as an installation point to achieve the positioning and installation of the part 2. The installation process is simple and facilitates the installation of the part 2.

[0056] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments.
