Technical Field

[0001] This utility model relates to a quick-release structure for a car rear seat, belonging to the field of automotive parts technology. Background Technology

[0002] Currently, the rear seats of passenger cars generally adopt a one-piece structure, with the middle seat fixedly connected to the two side seats. While this structure has certain advantages in terms of design and strength, it presents significant inconveniences in daily use. For example, the space under the middle rear seat is narrow, and passengers often place small items, snacks, or drinks there, making them difficult to clean if they fall or leak. Furthermore, when the middle seat needs replacement, repair, or cleaning, because it is an integral part of the entire rear seat structure, the entire rear seat must be disassembled, a cumbersome and time-consuming process that increases labor costs and maintenance difficulty.

[0003] Existing detachable seat structures mostly use bolt connections or exposed clips for fixing. These structures require tools to disassemble and assemble, involve many steps, and are prone to loosening of the clips or noise problems after long-term use, which is detrimental to the comfort and safety of the vehicle. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of existing passenger cars where the middle part of the rear seat cannot be disassembled independently, the disassembly and assembly process is complicated, and cleaning and maintenance are inconvenient.

[0016] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] like Figure 1 As shown, one embodiment of this utility model is a quick-release structure for a car rear seat, including a seat component 1, a metal fixing tube 2 installed in the seat component 1, and a fixing bracket 3 for engaging with the metal fixing tube 2.

[0019] The metal fixing tube 2 is integrally embedded in the foaming process of the seat component 1. That is, the metal fixing tube 2 is pre-placed in the seat foaming mold, and the foaming material covers it to form an integral structure, thereby enhancing the support strength and structural stability of the seat component 1.

[0020] The metal fixing tube 2 includes a longitudinal locking part 21 and a horizontal locking part 22; the two are in an "L"-shaped continuous structure, which are used to cooperate with the longitudinal locking groove 31 and the horizontal locking groove 32 of the fixing seat 3 respectively to realize the dual restriction of the seat in the longitudinal and horizontal directions.

[0021] It should be mentioned that this embodiment provides a structure for a metal fixing tube 2. The horizontal locking part 22 is formed by bending one end of the metal fixing tube 2 around to form a longitudinal locking part 21, thereby forming a structure similar to a coil spring. The purpose of this structure is to achieve elasticity between the horizontal locking part 22 and the longitudinal locking part 21, so that when the chair back where the longitudinal locking part 21 is located is pressed, flexible extension and retraction can be achieved through the bending structure.

[0022] In this embodiment, the fixing bracket 3 is configured as an "L"-shaped structure, with a longitudinal locking groove 31 at one end and a horizontal locking groove 32 at the other end. The longitudinal locking groove 31 is an upwardly extending "hook"-shaped structure used to limit the longitudinal locking part 21 from above. The horizontal locking groove 32 is used to accommodate the horizontal locking part 22.

[0023] like Figure 4 As shown, since the seat component 1 and the metal fixing tube 2 are integrally formed, in order to ensure that the metal fixing tube 2 can be engaged with the fixing bracket 3, the back of the seat component 1 is provided with a first slot 11, and the longitudinal engaging part 21 of the metal fixing tube 2 is engaged with the longitudinal engaging groove 31 through the first slot 11; the bottom end of the seat component 1 is provided with a second slot 12, and the horizontal engaging part 22 of the metal fixing tube 2 is engaged with the horizontal engaging groove 32 through the second slot 12, thereby realizing the quick loading and unloading of the rear seat component 1.

[0024] like Figure 2 and Figure 3 As shown, a pressing member 221 is provided at the horizontal locking groove 32. The pressing member 221 includes a protruding fixing frame 2211 and a limiting block 2212 mounted on the fixing frame 2211. The limiting block 2212 can rotate in the direction perpendicular to the fixing frame 2211. Specifically, the limiting block 2212 is configured as a spindle-like structure, and the pressing member 221 is made of an elastic plastic structure, thereby enabling the limiting block 2212 to move slightly within the locking range. When the horizontal locking part 22 of the metal fixing tube 2 is inserted into the horizontal locking groove 32, the limiting block 2212 moves under the action of force. When the horizontal locking part 22 is locked into the horizontal locking groove 32, the limiting block 2212 rebounds, thereby locking the horizontal locking part 22 and forming a stable lock. When disassembly is required, pressing the back of the seat component 1 pushes the longitudinal locking part 21. The horizontal locking part 22 is released from the longitudinal locking groove 31 by the elasticity of the material between the horizontal locking part 22 and the longitudinal locking part 21, thus achieving quick disassembly and assembly.

[0025] In the mounting direction of the fixed bracket 3, a stop 222 is provided to cooperate with the pressing member 221. When the horizontal locking part 22 is inserted, the stop 222 and the pressing member 221 form a clamping engagement, making the horizontal locking more secure.

[0026] In this embodiment, two horizontal locking slots 32 and two vertical locking slots 31 can be linearly arranged on the fixed card holder 3 to achieve a stable two-point installation in the middle of the seat, enhance structural strength and prevent shaking.

[0027] To further enhance the overall strength of the fixed bracket 3, a reinforcing member 4 can be installed on the surface of the fixed bracket 3. The surface of the reinforcing member 4 is provided with an opening 41. The fixed bracket 3 passes through the opening 41 and is engaged with the metal fixing tube 2, which plays an auxiliary role in limiting and bearing the load.

[0028] In this embodiment, the seat component 1 and the metal fixing tube 2 can adopt an integral molding structure, avoiding secondary welding or screwing processes, simplifying the production process, and improving production consistency and safety.

[0029] With the above structure, when the middle seat needs to be installed, simply align the longitudinal snap-fit ​​part 21 of the metal fixing tube 2 with the longitudinal snap-fit ​​groove 31 and insert it, then press the horizontal snap-fit ​​part 22 downward into the horizontal snap-fit ​​groove 32, and the limit block 2212 will automatically pop up to form a snap-fit ​​lock, thus completing the installation.

[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
