Description

Technical Field

[0001] The invention relates to the technical field of automobile seats, and in particular to a single-module installation structure and an automobile seat capable of realizing embracing support. Background Art

[0002] In the traditional structure of car seats, the backrest is generally an integral structure, and the support force mode and force point distribution of any passenger's back are almost the same. However, there are differences in body shape between different passengers, so from the perspective of ergonomics, such a backrest structure cannot form the best support force effect for all users, and there is room for optimization in comfort design.

[0003] In view of this technical status, the applicant intends to develop a new structural form of seat backrest, the core concept of which is that when the user's back is against the front side of the backrest, the center area of ​​the backrest can collapse and deform backward under pressure, so that the circumferential area of ​​the backrest can form an embracing support for the user's back, thereby better conforming to human mechanics and improving riding comfort. In this innovative design, what technical means are used to achieve the embracing support of the collapse and deformation of the center area of ​​the backrest is a technical problem that needs to be overcome urgently. Summary of the invention

[0004] In view of this, one of the objectives of the present invention is to provide a single-module installation structure that can achieve embracing support, aiming to solve the technical problems pointed out in the background technology.

[0005] To achieve the above purpose, the technical solution of the present invention is as follows:

[0006] A single module installation structure capable of realizing embracing support, the key of which is to include:

[0007] a backrest, wherein a base plate is disposed in the backrest, and the base plate is flexible; and

[0008] A support module installed in the side area of ​​the front side of the substrate, wherein the support module is arranged in the side area of ​​the substrate so as to be deflectable forward and backward by rotating the support mechanism;

[0009] The rotation support mechanism is arranged in the middle or outer area of ​​the support module. When the user's back is pressed on the inner end area of ​​the support module, the support module can deflect backward with the rotation support mechanism as a fulcrum, so that the support module forms an embracing support for the user's back.

[0010] With the above structure, when the user leans on the seat back, the user's back applies pressure to the support module backwards. Under the rotational connection between the support module and the base plate, the right end of the support module can rotate backwards with the rotation support mechanism as the fulcrum, that is, the inner side of the support module can form a backward concave state, thereby forming an embrace support for the user's back. Since the base plate is flexible, the base plate can be adaptively adjusted with the deformation of the support module and the dynamic changes of the human body posture, further enhancing the embrace support effect of the seat on the human body and improving the user experience.

[0011] Preferably, the rotation support mechanism is a ball joint structure arranged between the support module and the base plate. With the above structure, the ball joint structure can increase the flexibility of the rotation of the support module to better adapt to the user's back.

[0012] Preferably, the base plate is provided with a mounting groove extending backwards, and the rotation support mechanism includes a ball joint seat and a ball head, the ball joint seat is fixedly installed in the mounting groove, and the ball head is fixedly installed at the rear side of the support module. With the above structure, when the support module is subjected to pressure from the user's back, the right end of the support module can rotate backwards with the ball joint seat as the center.

[0013] Preferably, two rotation support mechanisms are provided, and the two rotation support mechanisms are located at the deflection center line of the support module. The above structure can effectively disperse the pressure, avoid structural deformation or damage caused by single-point force, and at the same time, increase the stability and smoothness of the deflection movement of the support module.

[0014] Preferably, the inner end of the support module is fixedly connected to the base plate, and an elastic reset component is provided between the outer end and the base plate, and when the user's back is facing forward away from the backrest, the elastic reset component is used to reset the support module. The above structure not only ensures that the support module can automatically reset after being stressed, thereby improving the convenience and comfort of the seat, but also effectively reduces the risk of component fatigue and damage due to long-term use, thereby extending the overall service life of the seat.

[0015] Preferably, the elastic reset assembly includes a first mounting seat arranged at the outer end of the support module and a second mounting seat arranged on the base plate, and an elastic component is connected between the first mounting seat and the second mounting seat. With the above structure, when the inner side of the support module is subjected to pressure and then deflected, the outer end of the support module drives the first mounting seat to lift forward, so that the elastic component is stretched. When the user's back moves forward away from the backrest, the outer end of the base plate resets backward, and the elastic component releases elastic potential energy, which can drive the outer end of the support module to reset.

[0016] Preferably, the elastic component is a tension spring. The above structure has the advantage of being compact and can also absorb the vibration of the vehicle, reduce the rigid contact between the support module and the base plate, and greatly reduce the probability of abnormal noise.

[0017] As a preference, the elastic components are provided in two groups. With the above structure, the elastic reset assembly can more evenly bear and transmit the force on the outer end of the support module during operation, providing a more reliable and stable elastic reset function for the single module installation structure.

[0018] Preferably, the first mounting seat is connected to the supporting module by hanging, and / or the second mounting seat is fixedly mounted on the base plate by a fixing member. The above structure is adopted to facilitate the installation, maintenance and replacement of the elastic reset assembly.

[0019] The second object of the present invention is to provide a car seat, the key of which is: comprising the above-mentioned single-module installation structure, the support modules are installed in the left area and the right area of ​​the front side of the backrest.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. With the single-module installation structure for implementing enveloping support provided by the present invention, when the user leans on the seat back, the pressure on the inner end of the support module will be greater than that on the outer end. In addition, the base plate is flexible. Therefore, when the support module is under pressure, it can rotate backward as a whole with the rotating support mechanism as the fulcrum, that is, the support module moves in a swinging trajectory with the inner end toward the rear and the outer end toward the front, thereby implementing enveloping support for the user's back.

[0022] 2. The single-module installation structure for realizing embracing support provided by the present invention is adopted. The base plate is flexible and can adaptively adjust with the deformation of the supporting module and the dynamic changes of human body posture, thereby further enhancing the embracing support effect of the seat on the human body and improving the user experience.

[0023] 3. The single-module installation structure provided by the present invention can realize embracing support, and the rotation support mechanism is a ball joint structure. The ball joint structure can increase the flexibility of the support module rotation to better adapt to the user's back.

[0024] 4. When the user's back moves forward and away from the backrest, the tension provided by the elastic reset component can quickly reset the support module. At the same time, when hugging and supporting the user's back, the elastic reset component can eliminate the installation gap between the support module and the base plate to ensure riding comfort.

[0025] 5. When the car seat provided by the present invention is used, when the user's back is pressed against the inner end areas of the left and right support modules, the inner end areas of the two groups of support modules can be deflected backwards with the rotating support mechanism as a fulcrum, thereby realizing the embracing support of the human back by the side wings on both sides, which has the advantage of good comfort.

[0036] The present invention is further described below in conjunction with embodiments and drawings.

[0037] like Figure 1 and 10 As shown, a car seat includes a single-module mounting structure, the single-module mounting structure includes a backrest, and a substrate A is provided inside the backrest, and the substrate A is flexible. A support module B is installed in the front side area of ​​the substrate A, and the side referred to here can be the left, right, upper or lower area. In actual application, the support modules B are installed in the left and right areas of the front side of the substrate A, and the two groups of support modules B are symmetrically distributed. This embodiment will take the support modules B in the left area as an example for detailed description. Figure 3It can be seen that in this embodiment, the support module B includes a mounting plate B1 and a foam body B2 disposed on the mounting plate B1, wherein the mounting plate B1 is used to be mounted on the substrate A. Figure 4 The support module B, i.e., the middle area or the outer area of ​​the mounting plate B1, is provided with a rotation support mechanism 2, and the mounting plate B1 is arranged in the left side area of ​​the substrate A so as to be deflected forward and backward through the rotation support mechanism 2. When the user's back is pressed on the inner end area of ​​the support module B, i.e., the right end area of ​​the support module B, the support module B can be deflected backward with the rotation support mechanism 2 as a fulcrum, so that the support module B forms an embracing support for the user's back.

[0038] Based on the above structural design, when the user leans on the seat back, the pressure on the right end of the support module B will be greater than that on the left end. Under the rotational connection between the support module B and the base plate A, the support module B can rotate backward as a whole with the rotation support mechanism 2 as the fulcrum, that is, the support module B moves in a swinging trajectory with the inner end facing backward and the outer end facing forward, thereby forming an embracing support for the user's back. Since the base plate A is flexible, the base plate A can adaptively adjust with the deformation of the support module B and the dynamic changes of the human body posture, further enhancing the embracing support effect of the seat on the human body and improving the user experience.

[0039] Furthermore, in this embodiment, the rotation support mechanism 2 is a ball joint structure provided between the support module B and the base plate A. When the support module B is subjected to pressure from the user's back, it can rotate backwards with the ball joint as the center, and the ball joint structure can increase the flexibility of the rotation of the support module B to better adapt to the user's back.

[0040] Specifically, refer to Figure 3 and Figure 6 The base plate A is provided with a mounting groove A1 extending backwards, and the rotation support mechanism 2 includes a ball joint seat 21 and a ball head 22 adapted to the ball joint seat 21, wherein the ball joint seat 21 is fixedly installed in the mounting groove A1, and the ball head 22 is fixedly installed on the rear side of the mounting plate B1, and the ball head 22 can flexibly rotate in the ball joint seat 21. When the support module B is subjected to the back pressure of the user, the right end of the mounting plate B1 can rotate backwards with the ball joint seat 21 as the center.

[0041] like Figure 4 As shown, in this embodiment, two rotation support mechanisms 2 are provided, and the two rotation support mechanisms 2 are located at the deflection center line of the support module B and are arranged at intervals along the height direction of the support module B. The two sets of rotation support mechanisms 2 can effectively disperse the pressure, avoid structural deformation or damage caused by single-point force, and at the same time, can also make the movement of the mounting plate B1 more stable and smooth when rotating.

[0042] Combination Figure 4 and Figure 5As shown, in this embodiment, the rotation support mechanism 2 is arranged in the middle area of ​​the mounting plate B1, the inner end of the mounting plate B1, that is, the right end, is fixedly connected to the base plate A, and an elastic reset component 3 is arranged between the outer end, that is, the left end, and the base plate A. When the inner area of ​​the support module B rotates backward under pressure, the elastic reset component 3 can drive the outer end of the base plate A to lift forward with the ball joint as the fulcrum. When the user's back is facing forward and away from the backrest, the elastic reset component 3 can reset the support module B.

[0043] Based on this, when the support module B is subjected to pressure from the user's back, the mounting plate B1 can rotate backward with the rotating support mechanism 2 as the fulcrum, that is, the inner side of the mounting plate B1 is concave backward and the outer side is lifted forward. At this time, the elastic reset component 3 can drive the outer end of the substrate A to lift forward, thereby improving the wrapping of the backrest to the side of the user's back. When the user's back is facing forward away from the support module B, the substrate A can be restored to its initial state, that is, the outer end of the substrate A can be reset backward under the action of the elastic reset component 3, driving the outer end of the mounting plate B1 to rotate backward and reset, thereby restoring the support module B to its initial state. The setting of the elastic reset component 3 not only ensures that the support module B can automatically reset after being subjected to force, but also, when embracing and supporting the user's back, the elastic reset component 3 can eliminate the installation gap between the support module B and the substrate A, thereby improving the convenience and comfort of the seat.

[0044] For further information, see Figure 5 and 7 The elastic reset assembly 3 includes a first mounting seat 31, a second mounting seat 32, and an elastic component 33 arranged between the first mounting seat 31 and the second mounting seat 32. In the present embodiment, the elastic component 33 is a tension spring. The first mounting seat 31 is arranged on the inner side of the outer end of the mounting plate B1, and the second mounting seat 32 is arranged on the side of the substrate A opposite to the first mounting seat 31. The two ends of the tension spring are respectively connected to the first mounting seat 31 and the second mounting seat 32. When the inner side of the support module B is subjected to pressure and is recessed backward, the mounting plate B1 deflects with the rotating support mechanism 2 as a fulcrum, and the outer end of the mounting plate B1 drives the first mounting seat 31 to lift forward, so that the tension spring is stretched. When the user's back is facing forward away from the backrest, the outer end of the substrate A resets backward, and the tension spring releases the elastic potential energy, which can drive the outer end of the mounting plate B1 to reset, thereby restoring the support module B to its initial state.

[0045] Combination Figure 2 and Figure 3As shown, in order to facilitate the replacement and disassembly of the support module B, the inner end of the mounting plate B1 is connected to the base plate A through the hanging assembly 1. Specifically, the hanging assembly 1 includes a hanging groove 11 arranged on the base plate A and a hanging member 12 arranged on the back side of the mounting plate B1. The hanging member 12 can be stably supported in the hanging groove 11, ensuring the convenience and stability of the installation of the mounting plate B1. In this embodiment, the hanging groove 11 adopts a through hole design. This structural design is convenient for hanging and can reduce the weight of the base plate A.

[0046] Specifically, refer to Figure 3 The hanging groove 11 includes a guide section 111 and a fixed section 112 which are connected in sequence from top to bottom. The guide section 111 is configured to be wide at the top and narrow at the bottom. Its inclined inner wall can guide the hanging member 12 during the installation process, so that the hanging member 12 can smoothly enter the hanging groove 11. The hanging member 12 includes an extension portion 121 protruding backward along the back side of the mounting plate B1. The outer end of the extension portion 121 is provided with a limit portion 122. The diameter of the limit portion 122 is larger than that of the extension portion 121. The extension portion 121 is adapted to the fixed section 112. During installation, the mounting plate B1 is hung from top to bottom. The limit portion 122 passes through the guide section 111. The extension portion 121 enters the fixed section 112 downward under the guidance of the guide section 111 and is stably fixed at the bottom of the fixed section 112. At this time, the limit portion 122 can prevent the extension portion 121 from escaping from the fixed section 112, so as to ensure that the connection between the mounting plate B1 and the substrate A is stable and reliable.

[0047] In addition to the above embodiments, the hook assembly 1 can also refer to Fig. 9 That is, the hanging groove 11 is set on the mounting plate B1, and the hanging member 12 is set on the base plate A (not shown in the figure). In this embodiment, the guide section 111 and the fixing section 112 in the hanging groove 11 are designed to be connected from bottom to top, and the guide section 111 is wide at the bottom and narrow at the top. Considering this, during installation, the mounting plate B1 can also be installed and hung from top to bottom, ensuring the stability of the connection between the mounting plate B1 and the base plate A.

[0048] In this embodiment, there are two groups of hanging components 1, and the two groups of hanging components 1 are distributed along the height direction of the mounting plate B1. This layout significantly enhances the stability of the connection between the mounting plate B1 and the base plate A, so that the mounting plate B1 can be subjected to balanced force.

[0049] In this embodiment, the elastic reset assembly 3 is detachably installed between the mounting plate B1 and the base plate A. This design facilitates the installation, maintenance and replacement of the elastic reset assembly 3 .

[0050] For further reference, Figure 8The first mounting seat 31 and the mounting plate B1 are detachably connected by hanging. The specific structure can refer to the above-mentioned hanging component 1. After the first mounting seat 31 is stably hung on the mounting plate B1, the second mounting seat 32 is fixedly mounted on the substrate A by bolts and other fixing parts.

[0051] In this embodiment, two groups of elastic components 33 are provided, which are arranged at intervals along the height direction of the first mounting seat 31. This layout enables the elastic reset assembly 3 to more evenly bear and transmit the force on the outer end of the mounting plate B1 during operation, providing a more reliable and stable elastic reset function for the single-module mounting structure of the seat back.

[0052] like Figure 4 As shown, in this embodiment, the inner end of the mounting plate B1 extends to the middle of the base plate A, and the outer end extends to the edge of the base plate A, and the outer end of the mounting plate B1 is tilted forward relative to the base plate A. The forward tilted portion of the mounting plate B1 corresponds to the side wing of the seat, which can enrich the seat shape and provide lateral support to the side of the user's back. At the same time, when the user's back presses against the backrest, the bent portion can better fit the curve of the human back, providing the user with a more fitting and comfortable embracing support.

[0053] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make various similar expressions without violating the purpose and claims of the present invention, and such changes all fall within the scope of protection of the present invention.
