Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, specifically to a single-module installation structure and an automotive seat capable of adaptive wrap-around support. Background Technology

[0002] In the traditional structure of car seats, the backrest is generally a one-piece construction, and the way the force is applied to the back of any occupant is almost identical, as is the distribution of the force points. However, there are differences in body shape among different occupants, so from an ergonomic point of view, this backrest structure cannot provide the best support effect for all users, and there is room for optimization in comfort design.

[0003] Given the current state of technology, the applicant intends to develop a new structural form of seat backrest. The core concept is that when the user's back rests against the front of the backrest, the central area of ​​the backrest can collapse and deform backward under pressure, allowing the circumferential area of ​​the backrest to provide a wraparound support for the user's back, thus better conforming to ergonomics and improving seating comfort. In this innovative design, determining the technical means to achieve this wraparound support through the collapse and deformation of the central area of ​​the backrest is a crucial technical challenge that needs to be overcome. Utility Model Content

[0004] In view of this, one of the objectives of this utility model is to provide a single-module installation structure that can adaptively support a surrounding structure, aiming to solve the technical problems pointed out in the background art.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A single-module mounting structure capable of adaptive circumferential support, the key features of which include:

[0007] Backrest, wherein a base plate is provided inside the backrest, the base plate being flexible; and

[0008] A support module is installed in the front side region of the substrate. The support module can be rotated back and forth in the side region of the substrate by means of a rotating support mechanism.

[0009] The rotating support mechanism is arranged in the middle or outer area of ​​the support module. When the user's back is pressed against the inner end area of ​​the support module, the support module can deflect backward with the rotating support mechanism as the fulcrum, so that the support module can provide circumferential support for the user's back.

[0010] With the above structure, when the user leans on the seat back, the back of the user exerts pressure on the support module, and under the action of the rotating connection between the support module and the base plate, the right end of the support module can rotate backward around the rotating support mechanism, that is, the inner side of the support module can form a concave state to the rear, thereby forming a surrounding support to the back of the user. Since the base plate is flexible, the base plate can adaptively adjust with the deformation of the support module and the dynamic change of the human body posture, further enhancing the surrounding support effect of the seat on the human body and improving the user experience.

[0011] As a preferred, the rotating support mechanism is a spherical hinge structure arranged between the support module and the base plate. With the above structure, the spherical hinge structure can increase the flexibility of the rotation of the support module to better adapt to the back of the user.

[0012] As a preferred, the base plate is provided with a rearwardly extending mounting groove, and the rotating support mechanism comprises a spherical hinge seat and a ball head, the spherical hinge seat is fixedly installed in the mounting groove, and the ball head is fixedly installed on the rear side of the support module. With the above structure, when the support module is subjected to the pressure of the back of the user, the right end of the support module can rotate backward around the spherical hinge seat.

[0013] As a preferred, the rotating support mechanism is provided with two, and the two rotating support mechanisms are located at the deflection center line of the support module. With the above structure, the pressure can be effectively dispersed to avoid structural deformation or damage caused by single-point stress, and meanwhile, the stability and smoothness of the deflection movement of the support module can be increased.

[0014] As a preferred, the inner end of the support module is fixedly connected with the base plate, and the elastic reset component is arranged between the outer end of the support module and the base plate, and the elastic reset component is used to reset the support module when the back of the user is away from the backrest. With the above structure, not only the support module can be automatically reset after being stressed to improve the convenience and comfort of the use of the seat, but also the risk of fatigue and damage of the components caused by long-term use can be effectively reduced to prolong the overall service life of the seat.

[0015] As a preferred, the elastic reset component comprises 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 deflected under pressure, the outer end of the support module drives the first mounting seat to lift forward, so that the elastic component is stretched. When the back of the user is away from the backrest, the outer end of the base plate is reset backward, the elastic component releases the elastic potential energy, and the outer end of the support module can be reset.

[0016] Preferably, the elastic component is a tension spring. With the above structure, the structure is compact, and the vibration of the vehicle can be absorbed, the rigid contact between the support module and the base plate is reduced, and the probability of abnormal sound is greatly reduced.

[0021] 1. The single-module mounting structure provided by the utility model can adaptively embrace and support, when a user leans on the seat back, the pressure on the inner end of the support module is greater than that on the outer end, and the base plate is flexible, so that the support module can rotate as a whole around the rotating support mechanism as a fulcrum during the pressure process, that is, the inner end of the support module moves along a swing trajectory towards the outer end and the front of the backrest, thereby realizing the embrace and support of the user's back.

[0036] The present invention will be further described below with reference to the embodiments and accompanying 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, within which a base plate A is disposed. The base plate A is flexible. A support module B is mounted on the front side region of the base plate A. This side region can be the left, right, upper, or lower region. In practical applications, support modules B are mounted on both the left and right sides of the front side of the base plate A, with the two sets of support modules B symmetrically distributed. This embodiment will use the support module B in the left region as an example for detailed explanation. Figure 3It can be seen that in the embodiment, the support module B comprises a mounting plate B1 and a foam body B2 arranged on the mounting plate B1, wherein the mounting plate B1 is used for being mounted to the base plate A. Referring to Figure 4 , the support module B, that is, the middle region or the outer region of the mounting plate B1 is provided with the rotating support mechanism 2, and the mounting plate B1 is arranged on the left side region of the base plate A in a front-back deflection manner through the rotating support mechanism 2. When the user's back is pressed against the inner end region of the support module B, that is, the right end region of the support module B, the support module B can be deflected backward with the rotating support mechanism 2 as a fulcrum, so as to form a wraparound support to the user's back.

[0038] Based on the above structural design, when the user leans against the seat back, the right end of the support module B will bear greater pressure than the left end. Under the action of the rotating connection between the support module B and the base plate A, the support module B can rotate backward as a whole with the rotating support mechanism 2 as a fulcrum, that is, the support module B moves in a swinging trajectory with the inner end moving backward and the outer end moving forward, thereby forming a wraparound support to the user's back. Since the base plate A is flexible, the base plate A can be self-adaptively adjusted according to the deformation of the support module B and the dynamic change of the human body posture, thereby further enhancing the wraparound support effect of the seat to the human body and improving the user experience.

[0039] Further, in the embodiment, the rotating support mechanism 2 is a spherical hinge structure arranged between the support module B and the base plate A. When the support module B is pressed by the user's back, the support module B can rotate backward with the spherical hinge as a center, and the spherical hinge structure can increase the flexibility of the rotation of the support module B, so as to better adapt to the user's back.

[0040] Specifically, referring to Figure 3 and Figure 6 , the base plate A is provided with a rearwardly extending mounting groove A1, and the rotating support mechanism 2 comprises a spherical hinge seat 21 and a spherical head 22 matched with the spherical hinge seat 21, wherein the spherical hinge seat 21 is fixedly installed in the mounting groove A1, the spherical head 22 is fixedly installed on the rear side of the mounting plate B1, and the spherical head 22 can rotate flexibly in the spherical hinge seat 21. When the support module B is pressed by the user's back, the right end of the mounting plate B1 can rotate backward with the spherical hinge seat 21 as a center.

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

[0042] Combining Figure 4 and Figure 5As shown, in this embodiment, the rotating support mechanism 2 is located in the middle region of the mounting plate B1. The inner end, i.e., the right end, of the mounting plate B1 is fixedly connected to the substrate A, and the outer end, i.e., the left end, is provided with an elastic reset component 3 between itself and the substrate A. When the inner region of the support module B is subjected to pressure and rotates backward, the elastic reset component 3 can drive the outer end of the substrate 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 around the rotating support mechanism 2. That is, the inner side of the mounting plate B1 is concave backward, while the outer side is raised forward. At this time, the elastic reset component 3 can lift the outer end of the base plate A forward, thereby improving the backrest's support for the user's back. When the user's back moves forward away from the support module B, the base plate A can return to its initial state. In other words, the outer end of the base plate A, under the action of the elastic reset component 3, can rotate the outer end of the mounting plate B1 backward and reset, thus restoring the support module B to its initial state. The elastic reset component 3 not only ensures that the support module B can automatically reset after being subjected to force, but also eliminates the installation gap between the support module B and the base plate A when supporting the user's back, improving the convenience and comfort of the seat.

[0044] For further details, please refer to Figure 5 and 7 The elastic reset assembly 3 includes a first mounting base 31, a second mounting base 32, and an elastic component 33 disposed between the first mounting base 31 and the second mounting base 32. In this embodiment, the elastic component 33 is a tension spring. The first mounting base 31 is disposed on the inner side of the outer end of the mounting plate B1, and the second mounting base 32 is disposed on the side of the substrate A opposite to the first mounting base 31. The two ends of the tension spring are respectively connected to the first mounting base 31 and the second mounting base 32. When the inner side of the support module B is subjected to pressure and indents backward, the mounting plate B1 deflects around the rotating support mechanism 2 as a fulcrum, and the outer end of the mounting plate B1 drives the first mounting base 31 to lift forward, thereby stretching the tension spring. When the user's back moves forward away from the backrest, the outer end of the substrate A resets backward, and the tension spring releases its 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, to facilitate the replacement and disassembly of the support module B, the inner end of the mounting plate B1 is connected to the substrate A via a mounting assembly 1. Specifically, the mounting assembly 1 includes a mounting groove 11 disposed on the substrate A and a mounting member 12 disposed on the back side of the mounting plate B1. The mounting member 12 can be stably supported within the mounting groove 11, ensuring the convenience and stability of the mounting plate B1 during installation. In this embodiment, the mounting groove 11 adopts a through-hole design, which facilitates mounting and reduces the weight of the substrate A.

[0046] Specifically, refer to Figure 3 The mounting slot 11 includes a guide section 111 and a fixing section 112 connected sequentially from top to bottom. The guide section 111 is constructed with a shape that is wider at the top and narrower at the bottom. Its inclined inner wall can guide the mounting member 12 during installation, facilitating the smooth entry of the mounting member 12 into the mounting slot 11. The mounting member 12 includes an extension 121 protruding rearward along the back side of the mounting plate B1. The outer end of the extension 121 is provided with a limiting part 122. The diameter of the limiting part 122 is larger than that of the extension 121, and the extension 121 is adapted to the fixing section 112. During installation, the mounting plate B1 is mounted from top to bottom. The limiting part 122 passes through the guide section 111, and the extension 121 enters downward into the fixing section 112 under the guidance of the guide section 111 and is stably fixed at the bottom of the fixing section 112. At this time, the limiting part 122 can prevent the extension 121 from coming off the fixing section 112, ensuring a stable and reliable connection between the mounting plate B1 and the substrate A.

[0047] In addition to the above-described embodiments, the mounting component 1 can also be referred to Figure 9 That is, the mounting groove 11 is set on the mounting plate B1, and the mounting member 12 is set on the substrate A (not shown in the figure). In this embodiment, the guide section 111 and the fixing section 112 in the mounting groove 11 are designed to be connected from bottom to top, and the guide section 111 is wider at the bottom and narrower at the top. Considering this, during installation, the mounting plate B1 can also be installed and mounted from top to bottom, ensuring the stability of the connection between the mounting plate B1 and the substrate A.

[0048] In this embodiment, there are two sets of mounting components 1, which are distributed along the height of the mounting plate B1. This arrangement significantly enhances the stability of the connection between the mounting plate B1 and the substrate A, allowing the mounting plate B1 to be subjected to balanced forces.

[0049] In this embodiment, the elastic reset component 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 component 3.

[0050] Further reference Figure 8The first mounting base 31 and the mounting plate B1 are detachably connected by a hook. The specific structure can be referred to the hook assembly 1 mentioned above. After the first mounting base 31 is stably hooked on the mounting plate B1, the second mounting base 32 is then fixedly installed on the base plate A by bolts and other fasteners.

[0051] In this embodiment, two sets of elastic components 33 are provided, which are arranged at intervals along the height direction of the first mounting base 31. This layout allows 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 substrate A, and the outer end extends to the edge of the substrate A. The outer end of the mounting plate B1 is inclined forward relative to the substrate A. The forward-inclined portion of the mounting plate B1 corresponds to the side wing portion of the seat, which can enrich the seat shape and provide lateral support for the user's back. At the same time, when the user's back applies pressure to the backrest, the bent portion can better conform to the curve of the human back, providing the user with a more fitting and comfortable wraparound support.

[0053] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model. Those skilled in the art, under the guidance of the present utility model, can make various similar representations without departing from the spirit and claims of the present utility model, and such modifications all fall within the protection scope of the present utility model.
