Description

Technical Field

[0001] The utility model relates to the technical field of automotive safety systems, and particularly relates to a housing. Background Art

[0002] When wearing a seat belt, the rear part of the webbing lock head will squeeze the tongue of the steel plate lock, causing unnecessary trouble. To solve this problem, solutions such as optimizing the design of the webbing lock or adjusting the shape of the tongue can be adopted. Optimizing the design of the webbing lock means redesigning the lock head of the webbing lock, and an arc or inclined surface can be added to make it smoothly transition when contacting the tongue of the steel plate lock, thereby reducing the squeezing phenomenon. Adjusting the shape of the tongue means modifying the tongue of the steel plate lock to have a more suitable profile, such as adding a reverse arc or inclined surface to adapt to the lock head of the webbing lock and reduce the squeezing between the two.

[0003] Although the above solutions can solve the problem of the rear part of the webbing lock head squeezing the tongue of the steel plate lock during wearing, the above solutions can only be applied to unprocessed products (referring to lock heads, tongues, etc.), and are not applicable to the already processed original products (requiring repair). Therefore, a new solution is urgently needed. Summary of the Utility Model

[0004] For this reason, the utility model provides a housing to solve the above technical problems.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A housing includes an upper housing and a lower housing. The front side and the lower side of the upper housing are open ends. The front side, the upper side, and the rear side of the lower housing are open ends. The upper housing is detachably fixed to the lower housing. The front open end of the upper housing and the open end of the lower housing form an installation opening adapted to the rear part of the webbing lock head. The rear open end of the lower housing forms an entrance and exit for the webbing to pass through. A convex part protruding towards the upper housing is provided inside the lower housing, and the convex part can extend into the webbing threading ring at the rear end of the webbing lock head.

[0007] Further, the material of the housing is a thermoplastic crystalline polymer.

[0008] Further, the upper housing is fixedly connected to the lower housing by snap connection.

Detailed implementation manners

[0028] In the following, only some exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.

[0029] Adjust the installation positions of the webbing lock and the steel plate lock so that their positional relationship is more reasonable during wearing and avoid directly pressing the lock tongue. Through research, it is found that only by extending the length of the existing webbing lock head can the problem of the rear part of the webbing lock head squeezing the lock tongue of the steel plate lock during wearing be avoided. For this reason, this embodiment provides a housing that can extend the overall length of the webbing lock head when used in cooperation with the existing webbing lock head.

[0030] As Figure 1-8As shown in the figure, the housing 1 includes an upper housing 11 and a lower housing 12, and the upper housing 11 is detachably fixed to the lower housing 12. The front side and the lower side of the upper housing 11 are open ends, and the front side, the upper side and the rear side of the lower housing 12 are open ends. The lower open end of the upper housing 11 corresponds to the upper open end of the lower housing 12, so that there is no interlayer inside the housing 1 formed by installing the upper housing 11 on the lower housing 12. After the upper housing 11 is installed on the lower housing 12, the front open end of the upper housing 11 and the open end of the lower housing 12 form a larger open end, which is the installation opening 13 of the housing 1, also called the adaptation opening. The installation opening 13 is adapted to the rear part of the webbing lock head 2. After the housing 1 and the webbing lock head 2 are installed together, the installation opening 13 just wraps around the outside of the webbing lock head 2. After the upper housing 11 is installed on the lower housing 12, the rear open end of the lower housing 12 forms an access opening 14 for the webbing 3 connected to the rear end of the webbing lock head 2 to enter and exit the housing 1. A convex portion 121 protruding upward toward the upper housing 11 is provided inside the lower housing 12. After the housing 1 and the webbing lock head 2 are installed, the convex portion 121 can extend into the webbing threading ring 21 at the rear end of the webbing lock head 2, so that the housing 1 and the webbing lock head 2 can be prevented from being separated.

[0031] The housing 1 provided in this embodiment is installed at the rear part of the webbing lock head 2. During installation, the lower housing 12 is installed first. The convex portion 121 is aligned with the webbing threading ring and inserted into it, and then the upper housing 11 and the lower housing 12 are fixed together, and the installation can be completed. The installation is extremely convenient; for the webbing lock head 2 installed with the housing 1, the overall length is increased, and the problem that the rear part of the webbing lock head 2 squeezes the steel plate lock tongue when wearing the seat belt can be effectively avoided.

[0032] In this embodiment, the upper housing 11 and the lower housing 12 are snap-fitted and fixed. Exemplarily, a hook 111 is provided at the snap-fitting position of the upper housing 11, and a slot 122 adapted to the hook 111 is provided at the snap-fitting position of the lower housing 12; alternatively, a slot 122 is provided at the snap-fitting position of the upper housing 11, and a hook 111 adapted to the slot 122 is provided at the snap-fitting position of the lower housing 12. By the way of the hook 111 being snapped into the slot 122, only by pressing the upper housing 11 in the direction of the lower housing 12 to make the hook 111 snap into the slot 122, the assembly of the housing 1 can be completed, which is simple and convenient. Preferably, a guiding surface is provided at the end of the hook 111 and the wall of the slot 122, so that the snap-fitting is more convenient.

[0033] In this embodiment, the material of the housing 1 is a thermoplastic crystalline polymer. On the one hand, it can increase the hardness of the housing 1, and on the other hand, it can make the bonding force of the snap-fitting structure greater, and the snap-fitted housing 1 is not easily opened.

[0034] In this embodiment, when the upper housing 11 and the lower housing 12 are snap-connected, they are positioned by positioning posts 112, which further enhances the convenience of snap-connection. Exemplarily, positioning posts 112 extending towards the lower housing 12 are provided inside the upper housing 11, and positioning holes 1231 inserted with the positioning posts 112 are provided inside the lower housing 12; alternatively, positioning posts 112 extending towards the upper housing 11 are provided inside the lower housing 12, and positioning holes 1231 inserted with the positioning posts 112 are provided inside the upper housing 11. Generally, at least two positioning posts 112 are provided. Preferably, two positioning posts 112 are provided, and the two positioning posts 112 are respectively arranged on the left and right sides of the convex portion 121, with a gap left between the positioning posts 112 and the convex portion 121; when the housing 1 is installed on the webbing lock head 2, the two positioning posts 112 are respectively stuck on the left and right sides at the rear of the webbing lock head 2, thus effectively preventing the housing 1 from swinging in the width direction of the webbing lock head 2.

[0035] In this embodiment, the positioning holes 1231 are provided on the convex posts 123, and rib plates 1121 are provided on the circumferential side of the positioning posts 112 away from the convex posts 123; when the housing 1 is installed on the webbing lock head 2, the column end of the convex post 123 (referring to the end facing the rib plate 1121) and the plate end of the rib plate 1121 (referring to the end facing the convex post 123) are respectively stuck on the upper and lower sides at the rear of the webbing lock head 2, thus effectively preventing the housing 1 from swinging in the thickness direction of the webbing lock head 2.

[0036] In this embodiment, the rear side of the convex portion 121 is an arc-shaped surface 1211 concave forward; when the housing 1 is installed on the webbing lock head 2, the arc-shaped surface 1211 of the convex portion 121 is almost in contact with the webbing threading loop 21, but is separated by the webbing 3. That is to say, the convex portion 121 and the webbing threading loop 21 sandwich the webbing 3 in the middle. Through the cooperation of the convex portion 121 and the webbing threading loop 21, and the cooperation of the installation opening 13 and the rear housing of the webbing lock head 2, the housing 1 is effectively prevented from moving in the length direction of the webbing lock head 2.
