Description

Technical Field

[0001] This application relates to the field of automotive seat belt technology, specifically to a double-locking buckle sleeve. Background Technology

[0002] Vehicles typically have dual-lock buckles installed in the rear seats. The lock heads of the dual-lock buckles are located inside the side of the rear seats, with only the upper part of the lock tongue interface extending outwards from the side wing of the seat cushion. The extended part is used to quickly engage with the seat belt lock tongue that extends down from the vehicle body.

[0003] The aforementioned double-lock fasteners typically employ a hybrid rigid-flexible connection design: one lock head is connected to one side of a fixed plate mounted within the seat frame via a rigid steel plate bracket; while the other lock head is flexibly connected to the other side of the fixed plate via a webbing strip. Because one lock head is connected via webbing, this flexible connection method lacks rigidity, causing the lock head to be in a free state when not in use, allowing it to rotate and swing freely. This also inconveniences passengers when fastening their seat belts, requiring them to manually locate and stabilize the lock head, thus impacting the user experience. Utility Model Content

[0004] Therefore, this application provides a double-locking cover to solve the problems of inconvenience in installation and poor user experience of existing double-locking locks.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] A double-locking cover includes: a first body and a second body connected together. The first body is fitted onto the lower part of a first lock head, and the second body is fitted onto the lower part of a second lock head. The first body and the second body are respectively adapted to the lower shape of the first lock head and the second lock head. The first lock head is used to connect to one side of a fixed plate installed in the seat frame via a steel plate bracket, and the second lock head is used to connect to the other side of the fixed plate via a webbing.

[0007] Optionally, the lower part of the first set body is symmetrically provided with two buckles along the width direction of the steel plate support, and the two buckles engage with the convex corners on both sides of the steel plate support.

[0008] Optionally, the sheath is made of nylon, plastic, or rubber.

[0009] The first and second sets are integrally formed.

[0010] Optionally, the bottom of the first sleeve is designed with an opening corresponding to the part where the first lock head is inserted into the steel plate bracket. The side of the first sleeve away from the second sleeve is provided with a first notch, and the bottom of the first sleeve is provided with a connector along the width direction. The two buckles are symmetrically arranged on both sides of the connector in the width direction.

[0011] Optionally, a connecting bridge is provided between the first set and the second set;

[0012] The bottom center region of the second sleeve is provided with a through hole, and the side of the second sleeve away from the first sleeve is provided with a second notch that communicates with the through hole.

[0013] Compared with the prior art, this application has at least the following beneficial effects:

[0014] 1. Based on further analysis and research of existing technical problems, this application provides a double-lock sleeve, including a first sleeve and a second sleeve, which wraps around the lower part of the two lock heads of the rear double-lock system in a vehicle, thereby lifting and fixing the lock heads. By integrating the two sleeves into one unit, the overall structure is simple, compact, and easy to use. This modular design not only facilitates installation and management but also provides effective support for the two lock heads, preventing them from swinging freely or falling off. At the same time, the lock heads are always held in a fixed position, eliminating the need for users to search for and stabilize them, enabling blind operation, convenient insertion, and significantly improving the user experience.

[0015] 2. The first set of the present application is fixed to the steel plate bracket by snap-fit, which effectively prevents the sheath from coming loose when the vehicle is bumpy or when the user inserts or removes the locking tongue, thus ensuring the stability of the entire component in long-term use.

[0016] 3. The sheath of this application is made of nylon or rubber, which has good strength, toughness and wear resistance. It not only provides effective rigid support for the lock head to prevent it from swinging and falling, but also has a low manufacturing cost, ensuring the reliability and service life of the product.

[0017] 4. The protective sleeve of this application includes a first body and a second body, which are connected by an integrally formed connecting bridge to form a structurally stable whole, providing effective support for the two lock heads. Attached Figure Description

[0028] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] In the description of this application: unless otherwise stated, "a plurality of" means two or more. The terms "first," "second," "third," etc., in this application are intended to distinguish the objects referred to and do not have any special meaning in terms of technical connotation (e.g., they should not be construed as an emphasis on importance or order). Expressions such as "including," "comprising," and "having" also mean "not limited to" (certain units, components, materials, steps, etc.).

[0030] The terms used in this application, such as "upper," "lower," "left," "right," and "middle," are generally used to indicate the general relative positional relationship for the purpose of intuitive understanding by referring to the accompanying drawings, and are not absolute limitations on the positional relationship in the actual product.

[0031] One embodiment of this application, such as Figures 1-7 As shown, a double-lock cover is provided, which wraps around the lower part of the two lock heads of the rear double-lock system through a contoured design.

[0032] The protective sleeve 1 includes: a first body 11 and a second body 12 connected together, which can be integrally formed; the first body 11 is fitted onto the lower part of the first lock head 2, and the shape of the first body 11 is adapted to the lower part of the first lock head 2, and is used to wrap the lower outer periphery and bottom of the first lock head 2, thereby providing effective support and lifting for the first lock head 2; the second body 12 is fitted onto the lower part of the second lock head 3, and the shape of the second body 12 is adapted to the lower part of the second lock head 3, and is used to wrap the lower outer periphery and bottom of the second lock head 3, thereby providing effective support and lifting for the second lock head 3; the first lock head 2 is used to connect to one side of the fixing plate 6 installed in the seat frame through the steel plate bracket 4, and the second lock head 3 is used to connect to the other side of the fixing plate 6 through the webbing 5.

[0033] Preferably, two buckles 15 are symmetrically arranged at the lower part of the first body 11 along the width direction of the steel plate support 4. These two buckles 15 are reliably fixed by engaging with the protruding corners 41 on both sides of the steel plate support 4, thereby effectively preventing the sheath from falling off during use.

[0034] Preferably, the sheath is made of PA6 (Nylon 6) or plastic or rubber material (TPV can be selected), which has strong strength, toughness and wear resistance to achieve the best snap-fit ​​durability and overall structural strength.

[0035] Based on the aforementioned material properties, the sheath (especially its snap-fit ​​parts) can undergo controllable elastic deformation when subjected to installation force, thus smoothly overcoming the protruding corner structure on the steel plate support. After the external force disappears, the sheath can immediately return to its original shape, thereby achieving a stable snap-fit ​​and tight wrapping.

[0036] Preferably, the bottom of the first sleeve 11 is designed with an opening corresponding to the part where the first lock head 2 is inserted into the steel plate bracket 4. The side of the first sleeve 11 away from the second sleeve 12 is provided with a first notch 111, and the bottom of the first sleeve 11 is provided with a connector 14 along the width direction. Two buckles 15 are symmetrically arranged on both sides of the connector 14 and are integrally connected.

[0037] Preferably, a connecting bridge 13 is provided between the first set 11 and the second set 12;

[0038] The bottom center region of the second sleeve 12 is provided with a through hole 121, and the side of the second sleeve 12 away from the first sleeve 11 is provided with a second notch 122 that communicates with the through hole 121.

[0039] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
