Description

Technical Field

[0001] This utility model relates to the field of automotive buckle technology, specifically a buckle structure for automobiles. Background Technology

[0002] With the continuous development and progress of the automotive market, car seats are the seats used when sitting in a car. Car seats can be divided into separate seats and long seats according to their shape, fixed seats, removable seats, and adjustable seats according to their function, and single seats, double seats, and multi-person seats according to the number of people they can seat. When installing car seats, the seat panel needs to be installed onto the seat frame with screws. For car seats, side panels are often used to protect their sides, thereby providing a certain amount of cushioning force and improving the overall quality of the interior. Therefore, they are often installed using clips.

[0003] Chinese Utility Model Patent Publication No. CN209492485U discloses an automotive buckle. This automotive buckle only requires fixing the buckle seat to one component to be connected, and then snapping the buckle core along with the other component to be connected onto the buckle seat. Installation can be completed in just two steps, simplifying the assembly process and improving production efficiency. However, this automotive buckle does not have a design for a snap-fit ​​structure between the two parts, which can easily lead to the male and female buckles falling off. Furthermore, it does not have a limiting structure, which can easily cause displacement after the male and female buckles are connected, thus affecting normal use. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a buckle structure for automobiles, which can effectively solve the problems in the prior art.

[0005] The technical solution adopted by this utility model is: a buckle structure for automobiles, including a male buckle and a female buckle that snaps into the male buckle. A connecting post is fixedly installed at the other end of the male buckle away from the female buckle. A connecting seat is fixedly installed at the other end of the connecting post away from the female buckle. A slot is opened at the other end of the connecting seat away from the female buckle. A through slot one and a through slot two are opened at the end of the female buckle away from the center line.

[0006] Preferably, the male buckle has an alignment groove at one end near the female buckle, and an alignment block adapted to the alignment groove is fixedly installed at one end of the female buckle near the male buckle.

[0007] Through the above technical solution, the design of the alignment groove and the alignment block allows the user to easily observe the insertion length after the two are engaged, and also serves to limit the movement of the two to prevent them from easily shifting.

[0008] Preferably, the alignment groove and alignment block have a circular cross-section, and there are two identical alignment grooves and alignment blocks with decreasing diameters.

[0009] The above technical solution, through the design of two alignment grooves and alignment blocks with decreasing diameters, forms a dual positioning effect. During vehicle operation, the cooperation between the two can effectively prevent the male and female fasteners from loosening due to vibration, further improving their limiting function.

[0010] Preferably, a plug is fixedly installed at the end of the male buckle near the female buckle, and a slot is provided at the center of the female buckle away from the male buckle, and the plug and the slot are plugged in.

[0011] The above technical solution facilitates the insertion of the male and female fasteners through the insertion of the rod and the slot, and also facilitates the engagement of the subsequent insert block with the limiting groove, thus playing a guiding role.

[0012] Preferably, a plug block is fixedly installed at the outer edge of the plug rod away from the center line, and a limiting groove is opened at the center of the female buckle away from the male buckle. The diameter of the end of the plug block near the female buckle is larger than the diameter of the end away from the female buckle and it is made of elastic material. The plug block and the limiting groove have the same shape.

[0013] Through the above technical solution, by designing the insert block and the limiting groove, when the male and female buckles are engaged, the insert rod can be inserted into the limiting groove, and the insert block can deform. Subsequently, since the upper diameter is smaller than the lower diameter, it can play a guiding role. It can not only realize the limiting function after the insert rod is connected to the slot, but also prevent the male and female buckles from detaching axially after engagement.

[0014] Preferably, there are multiple identical insert blocks and limiting grooves, and the multiple insert blocks and limiting grooves are distributed at equal intervals.

[0015] The above technical solution uses multiple equally spaced inserts and limiting grooves to evenly distribute the connection force between the male and female buckles, preventing excessive local stress from damaging the connection. At the same time, the cooperation of multiple inserts and limiting grooves further enhances the buckle's anti-detachment capability and improves the overall stability of the snap-fit ​​structure.

[0016] Preferably, the slot has a cross-section in the shape of a cross, and the diameter of the male buckle is larger than the diameter of the connecting seat.

[0017] With the above technical solution, when the male and female buckles are used as a whole, they can be easily and quickly snapped together with other parts through the "+" shaped slot. After connection, the connection can effectively prevent the connector from rotating and displacing in all directions, ensuring the stability of the connection.

[0018] Compared with the prior art, this utility model provides a snap-fit ​​structure for automobiles, which has the following advantages:

[0019] 1. The snap-fit ​​structure for automobiles, through the design of the insert block and the limiting groove, allows the insert rod to be inserted into the limiting groove when the male and female snap-fits are engaged. At the same time, the insert block deforms. Since the upper diameter is smaller than the lower diameter, it can play a guiding role during insertion. It can not only realize the limiting function after the insert rod is connected to the slot, but also prevent the male and female snap-fits from axially separating after engagement.

[0020] 2. The snap-fit ​​structure of this car uses the male and female snap-fit ​​as a whole. It can be easily and quickly snapped into other parts through the "+" shaped snap-fit ​​groove. After connection, it can effectively prevent the connector from rotating and displacing in all directions, ensuring the stability of the connection. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1: As Figure 1-7 As shown, the present invention provides a car buckle structure, including a male buckle 1 and a female buckle 8 that snaps into the male buckle 1. A connecting post 2 is fixedly installed at the other end of the male buckle 1 away from the female buckle 8. A connecting seat 3 is fixedly installed at the other end of the connecting post 2 away from the female buckle 8. A slot 4 is opened at the other end of the connecting seat 3 away from the female buckle 8. A through slot 9 and a through slot 10 are opened through the other end of the female buckle 8 away from the center line.

[0031] Specifically, the male buckle 1 has an alignment groove 5 at one end near the female buckle 8, and the female buckle 8 has an alignment block 13 that matches the alignment groove 5 fixedly installed at one end near the male buckle 1. The advantage is that, through the design of the alignment groove 5 and the alignment block 13, when the two are engaged, it is easy for the user to observe the length of the insertion, and it can also limit the two to prevent them from easily shifting.

[0032] Specifically, the alignment groove 5 and the alignment block 13 have a circular cross-section. There are two identical alignment grooves 5 and alignment blocks 13 with decreasing diameters. The advantage is that the design of two alignment grooves 5 and alignment blocks 13 with decreasing diameters creates a dual positioning effect. During vehicle operation, the cooperation between the two can effectively prevent the male buckle 1 and female buckle 8 from loosening due to vibration, further improving their limiting function.

[0033] Specifically, a plug rod 6 is fixedly installed at the end of the male buckle 1 near the female buckle 8, and a slot 11 is opened at the center of the female buckle 8 away from the male buckle 1. The plug rod 6 and the slot 11 are plugged in. The advantage is that the plug rod 6 and the slot 11 can be plugged in to facilitate the male buckle 1 and the female buckle 8, and can be plugged in to facilitate the subsequent engagement of the plug block 7 and the limiting groove 12, which can play a guiding role.

[0034] Example 2: Figure 2-7 As shown, this is an improvement on the previous embodiment.

[0035] Specifically, a plug block 7 is fixedly installed on the outer edge of the plug rod 6 away from the center line. A limiting groove 12 is opened at the center of the female buckle 8 away from the male buckle 1. The diameter of the end of the plug block 7 near the female buckle 8 is larger than the diameter of the end away from the female buckle 8 and it is made of elastic material. The plug block 7 and the limiting groove 12 have the same shape. The advantage is that, through the design of the plug block 7 and the limiting groove 12, when the male buckle 1 and the female buckle 8 are engaged, the plug rod 6 can be inserted into the limiting groove 12. At the same time, the plug block 7 can be deformed. Then, since the upper diameter is smaller than the lower diameter, it can play a guiding role. It can not only realize the limiting function after the plug rod 6 is connected to the slot 11, but also prevent the male buckle 1 and the female buckle 8 from separating axially after being engaged.

[0036] Specifically, multiple insertion blocks 7 and limiting grooves 12 are provided, and the multiple insertion blocks 7 and limiting grooves 12 are distributed at equal intervals. The advantage is that the connection force between the male buckle 1 and the female buckle 8 is evenly distributed through multiple equally spaced insertion blocks 7 and limiting grooves 12, avoiding excessive local force that could damage the connection. At the same time, the cooperation of multiple insertion blocks 7 and limiting grooves 12 further enhances the buckle's anti-disengagement ability and improves the overall stability of the snap-fit ​​structure.

[0037] Specifically, the slot 4 has a cross-shaped structure, and the diameter of the male buckle 1 is larger than the diameter of the connecting seat 3. The advantage is that when the male buckle 1 and the female buckle 8 are used as a whole, they can be easily and quickly snapped together with other parts through the cross-shaped slot 4. After connection, it can effectively prevent the connecting seat 3 from rotating and displacing in all directions, ensuring the stability of the connection.

[0038] Working Principle: During use, the design of the alignment groove 5 and the alignment block 13 allows the user to easily observe the insertion length after they are engaged, and also serves as a limit to prevent displacement. The design of two alignment grooves 5 and 13 with decreasing diameters creates a dual positioning effect. During vehicle operation, the cooperation between them effectively prevents the male buckle 1 and female buckle 8 from loosening due to vibration, further enhancing their limiting effect. The insertion rod 6 and slot 11 facilitate the insertion of the male buckle 1 and female buckle 8, and also facilitate the engagement of the subsequent insertion block 7 with the limiting groove 12, serving a guiding role. The design of the insertion block 7 and limiting groove 12 allows the insertion rod 6 to be inserted into the limiting groove 12 when the male buckle 1 and female buckle 8 are engaged. This allows the insert 7 to deform. Since the upper diameter is smaller than the lower diameter, it can act as a guide. It not only limits the connection between the insert rod 6 and the slot 11, but also prevents the male buckle 1 and the female buckle 8 from detaching axially after being engaged. Through multiple equally spaced inserts 7 and limiting grooves 12, the connection force between the male buckle 1 and the female buckle 8 is evenly distributed, avoiding excessive local force that could damage the connection. At the same time, the cooperation of multiple inserts 7 and limiting grooves 12 further enhances the anti-detachment capability of the buckle and improves the overall stability of the engagement structure. When the male buckle 1 and the female buckle 8 are used as a whole, they can be easily and quickly engaged with other parts through the "+" shaped slot 4. After connection, it can effectively prevent the connector 3 from rotating and displacing in all directions, ensuring the stability of the connection.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
