Description

Technical Field

[0001] This utility model belongs to the field of automotive seat technology and relates to a lightweight automotive seat backrest. Background Technology

[0002] As an important component supporting the back of passengers, the backrest of a car seat not only needs to have good structural strength and durability, but also needs to achieve weight optimization to reduce the energy consumption of the whole vehicle. The existing car seat backrests usually use metal or high-strength plastic frames as support structures. Although they can meet the basic load-bearing requirements, they generally have problems such as bulky structure, large weight, and low material utilization.

[0003] In conclusion, although some existing technical solutions have solved the problem of excessive weight by changing materials, there is still considerable room for improvement in reducing weight through frame structure design. Summary of the Invention

[0004] The purpose of this utility model is to address the aforementioned problems existing in the prior art by proposing a lightweight car seat backrest, comprising:

[0005] case;

[0006] The frame includes a lifting frame and a support frame, the support frame being connected to the housing, the lifting frame being movably connected to the support frame, and the support frame having a through hole;

[0007] A backrest, which is connected to the lifting frame.

[0008] In the aforementioned lightweight car seat backrest, the support frame is provided with a first connecting part, and the housing is provided with a second connecting part, wherein the first connecting part is connected to the second connecting part.

[0009] The aforementioned lightweight car seat back also includes fasteners that pass sequentially through the first connecting portion and the second connecting portion.

[0010] In the aforementioned lightweight car seat backrest, the first connecting part is provided with an inclined perforation, the second connecting part is provided with a connecting post, and the fastener passes through the perforation to connect with the connecting post.

[0011] The aforementioned lightweight car seat backrest also includes an adjusting component and a fixing component. The adjusting component is flexibly connected to the lifting frame, and the fixing component is slidably connected to the lifting frame. The adjusting component is provided with a guide groove, which is inclined relative to the sliding direction of the fixing component. The fixing component is provided with a guide block, which is accommodated in the guide groove.

[0012] The aforementioned lightweight car seat backrest also includes an elastic element, one end of which abuts against the lifting frame, and the other end of which abuts against the adjusting element.

[0013] In the aforementioned lightweight car seat backrest, the adjusting component and the lifting frame are respectively provided with positioning components, and the two ends of the elastic component are respectively sleeved on the positioning components.

[0014] In the aforementioned lightweight car seat backrest, the housing is also provided with the through hole.

[0015] In the aforementioned lightweight car seat backrest, the through holes are configured as hexagonal holes, and the support frame is honeycomb-shaped.

[0016] In the aforementioned lightweight car seat backrest, the frame is provided with reinforcing ribs.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. By reasonably setting through holes on the support frame, the material usage of the support frame itself is effectively reduced without affecting the overall structural strength, thus reducing the overall weight and achieving a lightweight design that helps to reduce the overall load on the car seat.

[0019] 2. By connecting the fasteners through the inclined perforations to the connecting columns, multiple inclined slopes are formed in the connection area between the support frame and the shell. This effectively increases the thickness of the support frame without increasing the amount of material, thereby improving the overall strength of the support frame to a certain extent.

[0020] 3. When multiple hexagonal through holes are closely arranged, the wall thickness between the holes is uniform and the material distribution is more reasonable. This can significantly reduce the weight of the support frame while maintaining excellent mechanical properties. This lightweight design reduces the overall weight of the product, making it easier to handle and install, and also reduces the consumption of raw materials. Attached Figure Description

[0034] The specific embodiments described herein are merely illustrative examples of this utility model patent. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or adopt similar methods to replace them, but without departing from the patent of this utility model or exceeding the scope defined by the appended claims.

[0035] like Figure 1 As shown, a lightweight car seat back includes: a shell 1, a frame 2, and a headrest 3.

[0036] The frame 2 includes a lifting frame 21 and a support frame 22. The support frame 22 is connected to the housing 1. The lifting frame 21 is movably connected to the support frame 22. The support frame 22 is provided with a through hole 221.

[0037] The cushion 3 is connected to the lifting frame 21.

[0038] Specifically, the lifting frame 21 is slidably connected to the support frame 22 and can move vertically under the guidance of the support frame 22, thereby achieving height adjustment. The headrest 3 moves synchronously with the lifting frame 21, thereby achieving flexible height adjustment of the headrest 3. The support frame 22 is provided with at least one through hole 221.

[0039] In this embodiment, by reasonably setting through holes 221 on the support frame 22, the material usage of the support frame 22 itself is effectively reduced without affecting the overall structural strength, the overall weight is reduced, and a lightweight design of the structure is achieved, which helps to reduce the overall load of the car seat.

[0040] like Figure 1 As shown, based on the above embodiment, the support frame 22 is provided with a first connecting part 222, and the housing 1 is provided with a second connecting part 11, wherein the first connecting part 222 is connected to the second connecting part 11.

[0041] In this embodiment, the first connecting part 222 is a strip structure disposed on both sides of the support frame 22, and the second connecting part 11 is two strip structures on the housing 1 corresponding to the first connecting part 222. By symmetrically distributing the first connecting part 222 and the second connecting part 11 on both sides of the support frame 22 and the housing 1, the double-sided support and constraint can effectively limit the swing of the support frame 22 during use, thereby firmly fixing the support frame 22 to the housing 1.

[0042] like Figure 1 As shown, based on the above embodiment, it also includes a fastener (not shown in the figure), which passes through the first connecting part 222 and the second connecting part 11 in sequence.

[0043] In this embodiment, the fastener passes through the first connecting part 222 and the second connecting part 11 in sequence, thereby realizing a detachable connection between the support frame 22 and the housing 1, which greatly simplifies the disassembly and assembly process when the support frame 22 or the housing 1 needs to be repaired or replaced.

[0044] like Figure 1 As shown, based on the above embodiment, the first connecting part 222 is provided with an inclined through hole 2221, the second connecting part 11 is provided with a connecting post 111, and the fastener passes through the through hole 2221 to connect with the connecting post 111.

[0045] Specifically, the first connecting part 222 is provided with an inclined through hole 2221, and the first connecting part 222 forms an inclined contact surface around the through hole 2221 that is perpendicular to the axis of the through hole 2221. The connecting post 111 on the second connecting part 11 is provided with an internal thread, and the fastener is a screw. The fastener is connected to the connecting post 111 through the through hole 2221 on the inclined surface.

[0046] In this embodiment, fasteners are connected to the connecting post 111 through the inclined perforation 2221, so that the connection area between the support frame 22 and the housing 1 forms multiple inclined slopes, which indirectly increases the thickness of the support frame 22 without increasing the material, thereby improving the overall strength of the support frame 22 to a certain extent.

[0047] like Figure 1 As shown, based on the above embodiment, it also includes an adjusting member 4 and a fixing member 5. The adjusting member 4 is vertically connected to the lifting frame 21, and the fixing member 5 is slidably connected to the lifting frame 21. The adjusting member 4 is provided with a guide groove 41, which is inclined relative to the sliding direction of the fixing member 5. The fixing member 5 is provided with a guide block 51, which is accommodated in the guide groove 41.

[0048] Specifically, the guide groove 41 on the adjusting member 4 is inclined to the sliding direction of the fixing member 5, and the guide block 51 on the fixing member 5 is accommodated in the guide groove 41. When the adjusting member 4 is pulled, the fixing member 5 can be moved. When the fixing member 5 extends out of the lifting frame 21, it can abut against the support frame 22, thereby controlling and locking the height of the lifting frame 21.

[0049] In this embodiment, the component force generated by the push or pull force applied by the user to the adjusting member 4 can drive the fixing member 5 to move, thereby realizing the transmission of force and the conversion of the direction of movement, so that the user can lock the height of the lifting frame 21 without having to put his hand inside the lifting frame 21.

[0050] like Figure 1As shown, based on the above embodiment, it also includes an elastic element (not shown in the figure), one end of which abuts against the lifting frame 21, and the other end of which abuts against the adjusting element 4.

[0051] In this embodiment, when the adjusting member 4 is pulled, the elastic member between the adjusting member 4 and the lifting frame 21 is compressed, and the fixing member 5 retracts into the lifting frame 21. At this time, the height of the lifting frame 21 can be adjusted. When the force applied to the adjusting member 4 disappears, the elastic member returns to its original position, pushing the adjusting member 4 away from the lifting frame 21, thereby causing the fixing member 5 to extend out of the lifting frame 21 and abut against the support frame 22, thereby locking the height of the lifting frame 21. The locking action can be completed automatically without the user having to apply pushing force again, thus optimizing the user experience.

[0052] like Figure 1 As shown, based on the above embodiment, the adjusting member 4 and the lifting frame 21 are respectively provided with positioning members 42, and the two ends of the elastic member are respectively sleeved on the positioning members 42.

[0053] In this embodiment, the adjusting member 4 and the positioning member 42 on the lifting frame 21 extend into both ends of the elastic member to prevent the elastic member from bending, twisting or shifting laterally during compression or elongation.

[0054] like Figure 1 As shown, based on the above embodiment, the housing 1 is also provided with the through hole 221.

[0055] Specifically, the housing 1 is also provided with through holes 221, which correspond to the through holes 221 on the support frame 22 in terms of position and arrangement. When the support frame 22 and the housing 1 are assembled, the through holes 221 on both are aligned or connected in space, thereby forming one or more continuous ventilation paths.

[0056] In this embodiment, this design achieves lightweight structure while significantly enhancing overall heat dissipation performance. The through holes 221 on the shell 1 and the support frame 22 are formed by removing excess material, effectively reducing the overall weight of the product while ensuring structural strength. In addition, the ventilation path formed by the through holes 221 on the shell 1 and the support frame 22 allows air to circulate between the back of the human body and the pillow 3, reducing stuffiness, which is especially suitable for long-term use scenarios.

[0057] like Figure 1 As shown, based on the above embodiment, the through hole 221 is configured as a hexagonal hole, and the support frame 22 is honeycomb-shaped.

[0058] Specifically, the through holes 221 are set as hexagonal holes, and multiple hexagonal through holes 221 are arranged in an array on the support frame 22 according to a certain pattern. The adjacent holes share sidewalls, so that the frame 2 presents a honeycomb-like geometric configuration as a whole, forming a "honeycomb" structure.

[0059] In this embodiment, when multiple hexagonal through holes 221 are closely arranged, the wall thickness between the holes is uniform and the material distribution is more reasonable. This can significantly reduce the weight of the support frame 22 while maintaining excellent mechanical properties. This lightweight design reduces the overall weight of the product, facilitates handling and installation, and also reduces the consumption of raw materials.

[0060] like Figure 1 As shown, based on the above-described embodiment, the frame 2 is provided with reinforcing ribs 23.

[0061] In this embodiment, the reinforcing rib 23 serves as the main load-bearing path, bearing the transmission and support of the main load. It can effectively disperse stress and prevent deformation, cracking, or fatigue failure caused by excessive local stress. On the frame 2 with a relatively thin overall wall thickness, it can reduce material consumption while ensuring overall strength.
