Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts manufacturing, and more specifically, to an automobile part connection buckle. Background Art

[0002] At the present stage, the competition in the automobile industry is becoming increasingly fierce, and the requirements for automobile production costs, part quality, etc. are gradually increasing, prompting researchers in the automobile industry to continuously explore various automobile parts with low cost and stable connection. Automobile headlights are important parts in the body structure, which can not only transmit driving signals but also affect the overall aesthetics of the vehicle. How to use simple parts to ensure the stable connection of automobile headlights is an important issue in the field of automobile parts manufacturing. The rear combination lamp of an automobile usually consists of a lamp housing, a decorative ring, and a lamp cover component. Among them, the decorative ring is usually fixed to parts such as the lamp housing and the lamp cover by snap connection.

[0003] For the snap connection in the rear combination lamp of an automobile, usually a single boss is integrally injection-molded on the decorative ring and then lapped on the lamp housing or lamp cover part. However, the conventional snap lapping structure is prone to looseness during use, and the connection stability is not high, resulting in position deviation. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of easy looseness and low connection stability during the use of the prior art, and provide an automobile part connection buckle, which is installed between the decorative ring and the lamp housing to provide a stable connection effect and avoid the looseness of the buckle during use.

[0005] To solve the above technical problems, the technical solution adopted by the utility model is:

[0006] Provide an automobile part connection buckle, including a buckle body. A first boss is provided at the top of the buckle body, and a second boss is provided at the bottom. A first groove is provided on the side of the first boss. The first boss includes a connection end connected to the buckle body and a movable end connected to the connection end.

[0007] The connecting buckle for automotive parts of the present utility model is installed on the card slot of the automotive parts. First, align the buckle body with the card slot, and then continuously push the buckle body to make the connecting end of the first boss enter the card slot. The first boss arranged in the first groove has elasticity and deforms under pressure until the movable end also completely passes through the card slot. Then, under the action of its own elasticity, the movable end bounces upward to fix the card slot between the movable end and the second boss. The movable end of the first boss and the second boss are respectively stuck at both ends of the card slot to limit the relative position between the card slot and the buckle, preventing the buckle from loosening during subsequent use. The first groove arranged on the side of the first boss enables the first boss to elastically deform under pressure, smoothly engage into the card slot, and the movable end can bounce upward to engage with the card slot. The overall structure of the connecting buckle for automotive parts of the present utility model is simple, suitable for installation between the decorative ring and the automotive lamp housing, providing a stable connection effect and preventing the buckle from loosening during use.

[0008] Further, the thickness of the first boss gradually increases from the connecting end to the movable end, that is, the first boss is inclined along the direction from the movable end to the connecting end, enabling the first boss to smoothly move in the card slot during the engaging process and avoiding unsmooth installation.

[0009] Further, the buckle body is installed in the card slot of the automotive parts. The movable end is provided with a first engaging portion that abuts against the card slot, and the second boss is provided with a second engaging portion that abuts against the card slot. The first engaging portion and the second engaging portion are respectively located on both sides of the card slot, and the acting forces between them and the card slot cooperate with each other to improve the connection stability between the card slot and the buckle and prevent loosening.

[0010] Further, both the first engaging portion and the second engaging portion are inclined surfaces, and the distance between the inclined surface and the card slot gradually decreases from the top surface to the bottom surface. The inclined first engaging portion and second engaging portion are in line contact with the card slot, and the acting force direction on the card slot is perpendicular to the inclined surface, further improving the fixing effect of the card slot and the buckle in the overlapping direction and enhancing the connection stability.

[0011] Further, the first boss and / or the second boss is provided with a first anti-slip protrusion. The first anti-slip protrusion can be arranged on both the first boss and the second boss to enhance the connection stability between the buckle and the card slot and prevent the buckle from sliding.

[0012] Further, the first groove is a U-shaped groove, and the axis of the first boss coincides with the axis of the first groove. The U-shaped first groove provides sufficient space for the elastic deformation of the first boss. By changing the width of the U-shaped groove, the elastic deformation range of the first boss can be controlled, and thus the engaging force between the first boss and the card slot can be adjusted to be suitable for different connection occasions.

[0013] Further, guiding portions are symmetrically arranged on both sides of the buckle body. During the process of inserting the buckle into the card slot, the symmetrical guiding portions can ensure that the whole buckle is in the central position in the card slot and provide a guiding function for the buckle.

[0014] Further, the side surface of the guiding portion is an inclined surface, a second groove is provided between the guiding portion and the buckle body, and the distance between the axis of the guiding portion and the first groove gradually increases from the top to the bottom of the buckle body. The second groove provides a space for the elastic deformation of the guiding portion, ensuring that it can approach the buckle body when the buckle is inserted into the card slot and smoothly enter. At the same time, it can bounce up to form a clamping connection with the card slot after the limiting protrusion passes through the card slot. During the insertion process, the guiding portion continuously approaches the buckle body, and the inclined guiding portion facilitates the smooth insertion of the buckle into the card slot and keeps it in the central position of the card slot.

[0015] Further, a limiting protrusion for restricting the clamping position is provided on the guiding portion. When the first boss passes through the card slot, the limiting protrusion also passes through the card slot synchronously. Under the action of the elasticity of the guiding portion itself, the guiding portion returns in the direction away from the buckle body, and the limiting protrusion is clamped with the card slot, enhancing the fixing effect of the buckle.

[0016] Further, a second anti-slip protrusion is provided on the guiding portion. The second anti-slip protrusion on the guiding portion can prevent relative sliding between the buckle and the card slot, avoid coming off during use, and improve the connection stability.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] 1. Provide a stable connection effect for automotive parts and avoid loosening of the buckle during use;

[0019] 2. The connection process between the buckle and the card slot is smooth, and the operation is simple and convenient;

[0020] 3. Ensure that the whole buckle is in the central position in the card slot and improve the installation accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Embodiment 1

[0028] This embodiment is the first embodiment of the connecting buckle for automobile parts, including a buckle body 100. A first boss 110 is provided on the top of the buckle body 100, a second boss 120 is provided on the bottom, a first groove 130 is provided on the side of the first boss 110, and the first boss 110 includes a connecting end 111 connected to the buckle body 100 and a movable end 112 connected to the connecting end 111.

[0029] Such as Figure 1As shown, during the connection process of the connection buckle in this embodiment, first align the buckle body 100 with the card slot 160, and insert the buckle into the card slot 160 along the second boss 120 towards the first boss 110. The connection end 111 first enters the card slot 160, and then the first boss 110 undergoes elastic deformation under the action of the card slot 160 and moves downward in the first groove 130 until the movable end 112 also completely passes through the card slot 160. At this time, the first boss 110 is no longer restricted by the card slot 160, and the elastic deformation is restored under the action of its own elasticity, and the movable end 112 bounces upward. One end of the card slot 160 abuts against the first boss 110, and the other end abuts against the second boss 120 at the bottom of the buckle body 100. The first boss 110 and the second boss 120 are aligned in the vertical direction, that is, they are on the same straight line in the clamping direction, ensuring the stable connection between the buckle and the card slot 160. The first groove 130 is arranged on the side of the first boss 110, providing a moving space for the elastic deformation of the first boss 110 and the reset of the movable end 112.

[0030] In this embodiment, the thickness of the first boss 110 gradually increases from the connection end 111 to the movable end 112. The first boss 110 is inclined and elastic, and the inclination direction is along the movable end 112 towards the connection end 111 connected to the buckle body 100, ensuring that the first boss 110 can be smoothly inserted into the card slot 160 and the movable end 112 can bounce back to the original position after completely passing through the card slot 160. The inclination angle of the first boss 110 is preferably 15° to 30°. If the inclination angle is too small, the clamping area between the movable end 112 and the card slot 160 after bouncing may be too small, affecting the clamping and fixing effect and being prone to come off during use; if the inclination angle is too large, it may be difficult to install the buckle into the card slot 160, reducing the assembly efficiency.

[0031] The buckle body 100 is installed in the card slot 160 of the automotive part. The movable end 112 is provided with a first matching portion 113 that abuts against the card slot 160, and the second boss 120 is provided with a second matching portion 121 that abuts against the card slot 160. The first matching portion 113 and the second matching portion 121 are respectively located on both sides of the card slot 160, and the acting forces between them and the card slot 160 cooperate with each other to improve the connection stability between the card slot 160 and the buckle and prevent the buckle from loosening.

[0032] The working principle of the automobile part connecting buckle in this embodiment is as follows: after aligning the buckle body 100 with the slot 160, the buckle body 100 is inserted into the slot 160, and the connecting end 111 enters first, and then the first boss 110 is elastically deformed in the first groove 130 until the movable end 112 also completely passes through the slot 160. At this time, the first boss 110 is no longer restricted by the slot 160, and the movable end 112 bounces upward, and one end of the slot 160 abuts against the inclined first matching portion 113, and the other end abuts against the inclined second matching portion 121 on the second boss 120.

[0033] Embodiment 2

[0034] This embodiment is the second embodiment of the automobile part connecting buckle. This embodiment is similar to the first embodiment, except that the first matching portion 113 and the second matching portion 121 in this embodiment are both inclined surfaces, and the distance between the inclined surface and the slot 160 gradually decreases from the top surface to the bottom surface.

[0035] After the buckle is connected to the slot 160, if the first matching portion 113 disposed on the movable end 112 is perpendicular to the buckle body 100, there is a slight gap between the first matching portion 113 and the slot 160. During use, the slot 160 may shake between the first matching portion 113 and the second boss 120, affecting the connection stability. Figure 2 As shown, the first matching portion 113 is inclined toward the slot 160, and its shape is set to be a trapezoid inclined to the buckle body 100, and the length of the bottom side is greater than the length of the top side. When the buckle is connected to the slot 160, the first matching portion 113 abuts against the slot 160, and the force of the first matching portion 113 on the slot 160 is perpendicular to the inclined surface, which can push the slot 160 to the position of the second boss 120, and cooperate with the second boss 120 to increase the fixing effect between the buckle and the slot 160 to avoid loosening.

[0036] like Figure 2 As shown, the second matching portion 121 is set to be an inclined surface inclined to the buckle body 100, gradually approaching the slot 160 from the top surface to the bottom surface. When the buckle is connected with the slot 160, the second matching portion 121 abuts against the slot 160. The force exerted by the second matching portion 121 on the slot 160 is perpendicular to the inclined surface, and the slot 160 can be pushed to the position of the first boss 110. Cooperating with the first boss 110 increases the fixing effect between the buckle and the slot 160 to avoid loosening.

[0037] The first groove 130 is a U-shaped groove, and the axis of the first boss 110 coincides with that of the first groove 130. The first boss 110 is located at the center of the U-shaped groove, and the U-shaped groove structure leaves enough space for the elastic deformation of the first boss 110. The widths of the first boss 110 and the first groove 130 can be adjusted according to the connection position. When the width of the first boss 110 increases and the width of the first groove 130 decreases, the degree of elastic deformation of the first boss 110 decreases, and a greater insertion force is required. After the buckle is connected to the card slot 160, the fixing effect is better. When the width of the first boss 110 decreases and the width of the first groove 130 increases, the elasticity of the first boss 110 is stronger, the degree of elastic deformation increases, the required insertion force is smaller, and it is easier to complete the installation between the buckle and the card slot 160.

[0038] First anti-slip protrusions 114 can be provided on both the first boss 110 and the second boss 120 of this embodiment. The second anti-slip protrusions 114 are provided on the first mating portion 113 of the first boss 110 and the second mating portion 121 of the second boss 120, and patterns such as leather grains, stepped protrusions, and wavy protrusions can be selected according to the usage scenarios. Both ends of the card slot 160 are in contact with the second anti-slip protrusions 114 to prevent the buckle from sliding.

[0039] The working principle of the automotive part connection buckle in this embodiment is as follows: Through the mutual cooperation of the inclined first mating portion 113 and the second mating portion 121, the connection stability between the buckle and the card slot 160 is improved. At the same time, the clamping force can be adjusted by changing the widths of the first boss 110 and the U-shaped groove, and first anti-slip protrusions 114 are provided on the first boss 110 and the second boss 120 to increase the friction force on each contact surface between the buckle and the card slot 160, prevent relative sliding between the buckle and the card slot 160, and enhance the connection stability.

[0040] Embodiment Three

[0041] This embodiment is the third embodiment of the automotive part connection buckle. This embodiment is similar to Embodiment One, except that guiding portions 140 symmetrically distributed are provided on both sides of the buckle body 100. During the process of inserting the buckle into the card slot 160, the symmetrical guiding portions 140 enter the card slot 160 simultaneously, providing a guiding effect for the buckle body 100, ensuring that the buckle body 100 is installed at the center position of the card slot 160 without position deviation, and improving the installation accuracy.

[0042] As Figure 1As shown, the side of the guiding part 140 is an inclined surface. A second groove 150 is provided between the guiding part 140 and the buckle body 100. The distance between the axis of the guiding part 140 and the first groove 130 gradually increases from the top to the bottom of the buckle body 100. The guiding part 140 inclined towards the buckle body 100 is more likely to enter the card slot 160, and the installation process is simpler and smoother. A linear second groove 150 is provided between the buckle body 100 and the guiding part 140, enabling the guiding part 140 to undergo elastic deformation during the installation process. When the buckle is installed into the card slot 160, the guiding part 140 approaches the buckle body 100 under the action of the card slot 160, and the area of the second groove 150 decreases; after installation is completed, the elastic deformation of the guiding part 140 is restored, and the area of the second groove 150 increases to the initial state, forming a stable connection between the buckle and the card slot 160.

[0043] As Figure 3 shown, a limit protrusion 141 for restricting the clamping position is provided on the guiding part 140. During the connection process between the buckle and the card slot 160, the guiding part 140 enters the card slot 160 together with the buckle body 100, ensuring that the buckle body 100 is always in the centered position. After installation is completed, the limit protrusion 141 passes through the card slot 160 and is no longer restricted by the card slot 160, and bounces up under the action of its own elasticity. The limit protrusion 141 abuts against the card slot 160, restricting the relative position of the buckle and the card slot 160 in the clamping direction, improving the fixing effect, and preventing the buckle from disengaging from the card slot 160 during use.

[0044] A second anti-slip protrusion 142 is provided on the guiding part 140 in this embodiment. As Figure 2 shown, the second anti-slip protrusion 142 can be in the shape of a step, a wave, etc., and is provided on the contact surface between the guiding part 140 and the card slot 160 to increase the friction force and prevent relative sliding between the guiding part 140 and the card slot 160. After the buckle is connected to the card slot 160, on the one hand, the guiding part 140 is limited by the limit protrusion 141, and on the other hand, the second anti-slip protrusion 142 is used to ensure that there is no relative sliding between the buckle and the card slot 160, enhancing the connection and fixing effect.

[0045] The working principle of the automotive part connection buckle in this embodiment is as follows: During the process of inserting the buckle into the card slot 160, the symmetrically arranged guiding parts 140 enter the card slot 160 simultaneously. The guiding part 140 inclined towards the buckle body 100 is smoothly inserted. The guiding part 140 approaches the buckle body 100, and the area of the second groove 150 decreases; after installation is completed, the guiding part 140 rebounds, the limit protrusion 141 is clamped with the card slot 160, and the second groove 150 returns to its original state. At the same time, a second anti-slip protrusion 142 is provided on the guiding part 140 to prevent relative sliding between the buckle and the card slot 160.

[0046] In the specific content of the above specific embodiments, each technical feature can be combined arbitrarily without contradiction. For the sake of concise description, not all possible combinations of the above technical features are described. However, as long as the combinations of these technical features do not exist in contradiction, they should be considered as the scope recorded in this specification.

[0047] Obviously, the above embodiments of the present invention are merely examples given to clearly illustrate the present invention, rather than limitations on the embodiments of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made on the basis of the above description.
