Description

Technical Field

[0001] This utility model belongs to the field of automotive seat technology and relates to an automotive seat with a novel support structure. Background Technology

[0002] With the development of the automotive industry and the increasing demands of users for driving and riding comfort, the functional design of car seats has received increasing attention. As one of the core components of human-computer interaction, car seats not only need to provide good support and riding experience, but also need to have flexible adjustment functions to adapt to the sitting posture needs of drivers or passengers of different body types.

[0003] In conclusion, although some existing technical solutions have solved the problem of adjusting the position and angle of car seats, the traditional steel tube support structure results in a relatively bulky overall structure, leaving considerable room for improvement. Summary of the Invention

[0004] The purpose of this utility model is to address the aforementioned problems in the existing technology by proposing a car seat with a novel support structure, comprising:

[0005] The support frame is equipped with a sliding groove;

[0006] A connecting assembly includes a connecting rod and at least two connectors, the connecting rod passing through the slide groove and having its two ends fixedly connected to the two connectors respectively, such that the connectors can slide relative to the support frame along the extension direction of the slide groove;

[0007] The base has a connecting groove, and the support frame is installed in the connecting groove and fixedly connected to the base;

[0008] The seat back is connected to the connector and is movable relative to the support frame as the connector slides along the groove.

[0009] In the aforementioned car seat with a novel support structure, the connector is provided with a contact plane, which is in contact with the seat back.

[0010] The aforementioned car seat with a novel support structure also includes fasteners that pass through the seat back and are connected to the connector.

[0011] The aforementioned car seat with a novel support structure also includes a shock-absorbing pad, and the fastener passes through the shock-absorbing pad and the seat back in sequence, and is finally connected to the connector.

[0012] The aforementioned car seat with a novel support structure also includes a locking element, which is slidably disposed on the seat back. The support frame is provided with at least one locking hole, and the locking element can be inserted into the locking hole to achieve position locking, or withdrawn from the locking hole to allow sliding.

[0013] The aforementioned car seat with a novel support structure also includes an adjustment handle, which is slidably connected to the seat back and its sliding direction is perpendicular to the sliding direction of the locking member. The adjustment handle is provided with an inclined guide groove, and the locking member is provided with a guide block, which is embedded in the guide groove and slidably engaged with it.

[0014] The aforementioned car seat with a novel support structure also includes an elastic element, one end of which abuts against the adjustment handle, and the other end of which abuts against the seat back.

[0015] In the aforementioned car seat with a novel support structure, there are at least two sliding grooves, both of which are arc-shaped. The two arc-shaped sliding grooves are arranged around the same center, so that the seat back moves along an arc path during the sliding process.

[0016] The aforementioned car seat with a novel support structure also includes a sliding pad, which is disposed on the inner circumferential side of the slide groove, and the connecting rod slides in cooperation with the slide groove through the sliding pad.

[0017] In the aforementioned car seat with a novel support structure, the seat back is further provided with a positioning groove, and the connecting rod is accommodated in the positioning groove.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. Compared to the traditional steel pipe structure, the new support frame has been optimized in terms of material selection and structural design, resulting in a significant reduction in overall weight. This makes the seat easier to move and adjust. At the same time, the sliding groove design on the support frame allows users to adjust the position of the seat back according to their personal sitting posture.

[0020] 2. A shock-absorbing pad is also provided between the fastener and the seat back for further cushioning and shock absorption. This not only significantly reduces the rigidity transmission and abnormal noise caused by direct contact between the fastener and the seat back, but also evenly distributes the preload applied by the fastener, reducing local compression damage to the seat back material. It is especially suitable for lightweight seat structures made of plastic, composite materials or sheet metal.

[0021] 3. The sliding pad is set on the inner circumference of the slide groove, mainly located in the contact area between the inner wall of the slide groove and the connecting rod. As an intermediate element to achieve sliding fit, the sliding pad effectively reduces the wear caused by direct contact between the connecting rod and the support frame, prevents scratches caused by long-term reciprocating motion, and extends the service life of the connecting rod and the support rod.

[0033] 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.

[0034] like Figures 1-4 As shown, a car seat with a novel support structure includes: a support frame 1, a connecting component 2, a base 3, and a seat back 4.

[0035] The support frame 1 is provided with a sliding groove 11.

[0036] The connecting assembly 2 includes a connecting rod 22 and at least two connecting members 21. The connecting rod 22 passes through the slide groove 11 and its two ends are respectively fixedly connected to the two connecting members 21, so that the connecting members 21 can slide relative to the support frame 1 along the extension direction of the slide groove 11.

[0037] The base 3 is provided with a connecting groove 31, and the support frame 1 is installed in the connecting groove 31 and fixedly connected to the base 3.

[0038] The seat back 4 is connected to the connector 21 and can move relative to the support frame 1 as the connector 21 slides along the slide groove 11.

[0039] Specifically, the support frame 1 is partially fixedly connected to the seat back 4 through the connecting component 2, avoiding the complex process of continuous welding or bolting of traditional steel pipes along the entire length of the backrest. This partial connection method not only greatly reduces the number of required connecting parts 21 and installation costs, but also simplifies the assembly process.

[0040] In this embodiment, compared with the traditional steel pipe structure, the new support frame 1 has been optimized in terms of material selection and structural design, and the overall weight has been significantly reduced, making the seat easier to move and adjust. At the same time, the slide groove 11 on the support frame 1 allows users to adjust the position of the seat back 4 according to their personal sitting posture habits.

[0041] like Figures 1-4 As shown, based on the above embodiment, the connector 21 is provided with a contact plane 211, which is in contact with the seat back 4.

[0042] Specifically, the contact surface 211 has good flatness and structural strength, and can achieve a large-area, stable fit with the corresponding installation area of ​​the seat backrest.

[0043] In this embodiment, the connecting rod 22 and the seat back 4 are stably connected by the contact plane 211 on the connector 21, which reduces the impact of vibration during use, can evenly distribute stress, and avoid material deformation or loosening of the connection due to local stress concentration.

[0044] like Figures 1-4 As shown, based on the above embodiment, a fastener 23 is also included, which passes through the seat back 4 and is connected to the connector 21.

[0045] Specifically, the fastener 23 is a bolt. The bolt passes through the seat backrest and the connector 21 in sequence and is connected to the connector 21 by a nut, thereby fixing the position of the seat backrest 4 and the connector 21.

[0046] In this embodiment, the seat back 4 and the connector 21 are connected by fastener 23. This through-type connection method is not only simple in structure and easy to assemble, but also has high connection strength and tensile and shear resistance even when the connector 21 or the seat back 4 is damaged and needs to be repaired or replaced. It can effectively withstand the complex stress generated by human body leaning and other behaviors during daily use.

[0047] like Figures 1-4 As shown, based on the above embodiment, it also includes a shock-absorbing pad 24. The fastener 23 passes through the shock-absorbing pad 24 and the seat back 4 in sequence, and is finally connected to the connector 21.

[0048] In this embodiment, a shock-absorbing pad 24 is also provided between the fastener 23 and the seat back 4 for further buffering and shock absorption. This not only significantly reduces the rigidity transmission and abnormal noise problems caused by direct contact between the fastener 23 and the seat back 4, but also evenly distributes the preload applied by the fastener 23, reducing the compression damage to the local material of the seat back 4. This is especially suitable for lightweight seat structures made of plastic, composite materials or sheet metal.

[0049] like Figures 1-4 As shown, based on the above embodiment, a locking member 41 is also included. The locking member 41 is slidably disposed on the seat back 4. The support frame 1 is provided with at least one locking hole 12. The locking member 41 can be inserted into the locking hole 12 to achieve position locking, or withdrawn from the locking hole 12 to allow sliding.

[0050] Specifically, the support frame 1 is provided with multiple locking holes 12 arranged at preset intervals to form a multi-level adjustment array. When the user adjusts the position of the seat back 4 according to the sitting posture requirements, the locking member 41 can be inserted into the locking hole 12 aligned with it, thereby fixing the support frame 1 and the seat back 4 relative to each other and realizing position locking.

[0051] In this embodiment, the design of locking member 41 and multi-hole locking hole 12 allows users to quickly find their preferred sitting posture and then lock it, ensuring the stability and safety of the seat back 4 and providing stable and comfortable support for users.

[0052] like Figures 1-4 As shown, based on the above embodiment, it also includes an adjustment handle 5, which is slidably connected to the seat back 4. Its sliding direction is perpendicular to the sliding direction of the locking member 41. The adjustment handle 5 is provided with an inclined guide groove 51, and the locking member 41 is provided with a guide block 411. The guide block 411 is embedded in the guide groove 51 and slides with it.

[0053] Specifically, the guide block 411 is embedded in the guide groove 51 and slides therewith, so that when the operating adjustment handle 5 moves along its sliding direction, the guide groove 51 pushes the guide block 411, causing the locking member 41 to move along its sliding direction, thereby disengaging from the locking hole 12.

[0054] In this embodiment, the user only needs to operate the adjustment handle 5 to make the locking member 41 exit from the current locking hole 12 and release the limiting state. At this time, the seat back 4 can slide freely along the arc-shaped slide groove 11 to a new position without the need to pull the locking member 41 separately, thus optimizing the user experience.

[0055] like Figures 1-4As shown, based on the above embodiment, it also includes an elastic element (not shown in the figure), one end of which abuts against the adjustment handle 5, and the other end of which abuts against the seat back 4.

[0056] In this embodiment, the elastic element continuously provides elastic restoring force to the adjusting handle 5, so that when the locking element 41 is aligned with the locking hole 12, it can be automatically inserted into the locking hole 12 to complete the locking action. This not only optimizes the user experience, but also effectively avoids safety hazards caused by negligence in not completing the locking.

[0057] like Figures 1-4 As shown, based on the above embodiment, the number of the slide grooves 11 is at least two, and both are arc-shaped. The two arc-shaped slide grooves 11 are arranged with the same center as the center, so that the seat back 4 moves along the arc path during the sliding process.

[0058] Specifically, the two arc-shaped slides 11 are set with the same center, which can ensure that the seat back 4 can move smoothly along the preset arc path during the sliding adjustment relative to the base 3.

[0059] In this embodiment, the double arc-shaped slide groove 11 design not only improves the guiding accuracy of the movement, but also significantly enhances the stability of the structure. When the seat back 4 is subjected to force and slides, the two slide grooves 11 cooperate with the corresponding connecting rods 22 to form a multi-point support linkage mechanism, which effectively prevents the backrest from deflecting during the movement.

[0060] like Figures 1-4 As shown, based on the above embodiment, a sliding pad 13 is also included. The sliding pad 13 is disposed on the inner circumferential side of the slide groove 11, and the connecting rod 22 slides in cooperation with the slide groove 11 through the sliding pad 13.

[0061] In this embodiment, the sliding pad 13 is disposed on the inner circumferential side of the slide groove 11, mainly located in the contact area between the inner wall of the slide groove 11 and the connecting rod 22. As an intermediate element for achieving sliding fit, the sliding pad 13 effectively reduces the wear caused by direct contact between the connecting rod 22 and the support frame 1, prevents scratches caused by long-term reciprocating motion, and extends the service life of the connecting rod 22 and the support rod.

[0062] like Figures 1-4 As shown, based on the above embodiment, the seat back 4 is also provided with a positioning groove 42, and the connecting rod 22 is accommodated in the positioning groove 42.

[0063] In this embodiment, the positioning groove 42 is provided on the inner side structure of the seat back 4, which is specifically used to accommodate and limit the connecting rod 22. The connecting rod 22 is embedded in the positioning groove 42 during assembly, and is connected to the seat back 4 through the connector 21. It is also connected to the sliding groove 11 to achieve an adjustable connection, so that the connecting rod 22 is always in a controlled spatial position during the movement.
