Description

Technical Field

[0001] This utility model relates to an automotive seat shell and its connecting buckle, belonging to the field of automotive seat technology. Background Technology

[0002] Car seat backrests are typically assembled from multiple plastic components connected by snap-fit ​​mechanisms. This snap-fit ​​connection method is widely used due to its ease of assembly. However, some existing snap-fit ​​designs on the market are too flimsy, making them prone to deformation, breakage, or disengagement under prolonged use, vibration, or unexpected stress. This can lead to loosening of the shell connections, abnormal noises, and even component separation, affecting the structural integrity and safety of the seat. Furthermore, existing snap-fit ​​designs may be difficult to disassemble without damage when repair or replacement is needed. Forcibly prying can easily damage the snaps themselves or the shell walls they connect to, rendering the parts unusable and increasing repair costs and difficulty. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide an automobile seat shell and its connecting buckle, which can improve the connection reliability between automobile seat shells and can be easily disassembled when maintenance or replacement of parts is required, thereby reducing maintenance costs and difficulties.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a car seat shell, comprising: A first housing, wherein the first housing is provided with at least one first fixing port; A second housing, wherein the second housing is provided with at least one second fixing port; The first housing has a latch on its inner side, and the second housing has a slot on its inner side; When the first housing abuts against the second housing, the latch is inserted into the slot to fix the first housing and the second housing in place, and the first fixing port and the second fixing port form a fixing cavity.

[0005] Furthermore, the first fixing port is provided with a first protrusion, and the second fixing port is provided with a second protrusion; When the first housing abuts against the second housing, the first boss and the second boss form a fixed platform.

[0006] Furthermore, the fixed cavity is provided with at least two locking holes, and the locking holes are provided with elastic locking plates.

[0007] This utility model also provides a connecting buckle for an automotive seat shell, including: The head, wherein the head is provided with a first operating cavity; The head is integrally formed with the body, and the body is provided with a second operating cavity, the first operating cavity and the second operating cavity are connected; The body has elastic locking blocks on both sides, which are adapted to the locking holes. The connecting buckle is adapted to pass through the fixing cavity and cooperate with the locking holes through the elastic locking blocks to achieve a fixed connection between the first housing and the second housing.

[0008] Furthermore, to facilitate disassembly, a connecting buckle for an automotive seat housing also includes an unlocking assembly. The unlocking assembly further includes an unlocking member, which is movably installed in the second operating cavity. The unlocking member is connected to the elastic locking block via at least two connecting members. One end of the connecting member is hinged to the elastic locking block, and the other end of the connecting member is hinged to the unlocking member.

[0009] Furthermore, a guide groove is installed on the inner wall of the second operating cavity, and a guide block adapted to the guide groove is installed on the locking member.

[0010] Furthermore, a connecting buckle for an automotive seat shell also includes a locking assembly, which includes a manual block, a locking buckle, and a locking groove. The manual block is movable in the first operating cavity, the locking buckle is installed on both sides of the manual block, the locking groove is installed in the first operating cavity, and the manual block is connected to the unlocking component. When the manual control block is in position, the locking buckle engages with the locking slot.

[0011] Furthermore, to prevent the connecting clips from falling off, multiple sets of elastic pads are also installed on the body.

[0012] By adopting the above technical solution, this utility model has the following beneficial effects: 1. In this utility model, the operator aligns and abuts the edges of the first housing and the second housing to ensure that the latch of the first housing is correctly inserted into the slot of the second housing. After the housings abut, the first fixing port on the first housing and the second fixing port on the second housing are aligned with each other to form a fixing cavity. The first protrusion on the first fixing port and the second protrusion on the second fixing port also align or combine with each other after abutting, forming a more stable fixing platform, providing support and positioning for subsequent connecting buckles. Then, align the body of the connecting buckle with the fixing cavity, press the head of the connecting buckle, and push it into the fixing cavity. During the insertion process, the elastic locking block of the body is squeezed and deformed. When it reaches the locking hole position, the elastic locking block springs into the locking hole, and the buckle is locked in the fixing cavity, thus firmly connecting the two shells. Push the manual block of the connecting buckle head to the designated position so that the locking buckle on it engages with the locking slot, thus locking and preventing accidental unlocking. 2. In this utility model, when the operator needs to disassemble the car seat shell, the operator opens the locking buckle on the hand block, pulls the hand block of the connecting buckle head to overcome the resistance between the locking buckle and the locking groove, so that it is disengaged. The hand block drives the unlocking part to move upward. The unlocking part pulls the elastic locking block through the connecting part. The elastic locking block contracts and deforms inward and disengages from the locking hole. At this time, the connecting buckle can be pulled outward. After removing the connecting clip, apply force to pull the first and second housings apart, and the latch will disengage from the slot, completing the disassembly. Attached Figure Description
