Description

Technical Field

[0001] The present invention relates to the technical field of automobile seat massage, and specifically relates to an offset drive mechanism lifting control module.

Background Art

[0002] With the progress of science and technology, the requirements for the comfort of automobile seats are continuously increasing. For passengers who drive or ride for a long time, due to maintaining the same posture for a long time, it is easy to cause physical fatigue and muscle stiffness. In order to solve the fatigue problem caused by long-term driving or riding, the number of seats equipped with a massage function is increasing.

[0003] In the prior art, the massagers in automobile seats are divided into two types: airbag type massage and mechanical massage. Among them, in the case of massage by airbag, the airbag made of a soft material acts on the waist and back areas of the user, the massage force is low, the massage effect is poor, and it is difficult to relax the user's body comprehensively and deeply. In the case of a mechanical massager, a rotatable massage device is often directly pressed against the user's back for massage. The massage method is relatively single, and it is difficult to comprehensively simulate the techniques such as kneading, pounding, and kneading and relaxing by manual massage. It is necessary to quickly improve the comfort experience.

[0004] Therefore, the applicant plans to develop a new mechanical multi-functional massage device with the aim of simulating functions such as pointing kneading, moving kneading, pointing tapping, moving tapping, and kneading so that the seat back can provide a more realistic artificial massage technique. In the context of this research and development, moving kneading, moving tapping, and kneading all require the massage actuator to move back and forth along the height direction of the backrest. Given the limited design space inside the car seat backrest, and the need to satisfy functions such as kneading, tapping, and kneading, how to position the lifting control mechanism for installing the massage device in this case has become an urgent technical challenge that needs to be resolved. [Overview of the project] [Problems that the invention aims to solve]

[0005] In view of this, the present invention provides a drive mechanism one-sided lifting control module, which has the advantages of a rational arrangement and good smoothness. [Means for solving the problem]

[0006] To achieve the above objective, the technical method of the present invention is as follows.

[0007] The seat is equipped with a reference plate to be installed inside the backrest of the seat, the reference plate having a sliding seat attached to it that is slidable along its height direction, the sliding seat having a guide member between one end in the width direction and the reference plate, a linear drive mechanism between the other end and the reference plate, a mounting area for mounting a massage mechanism in the center of the sliding seat having a mounting area in the center of the sliding seat, and the sliding seat being slidable along the height direction of the reference plate by the transmission action of the linear drive mechanism and the guiding and supporting action of the guide member.

[0008] According to the above structure, by arranging the linear drive mechanism and guide member on both sides, smooth vertical movement of the sliding seat can be achieved with fewer parts, and the predetermined mounting area in the center of the sliding seat provides sufficient space for designing the massage device.

[0009] Preferably, the linear drive mechanism comprises a screw fixed to the reference plate, a nut sleeve fitted onto the screw, and a motor that rotates the nut sleeve, the motor being fixed to a sliding seat, and the motor rotating the nut sleeve so that the nut sleeve can be helically raised and lowered along the axial direction of the screw.

[0010] Preferably, both ends of the screw are fixedly supported to the reference plate via a support base.

[0011] Preferably, the guide member comprises a guide rail fixed to a reference plate, the guide rail having a sliding chamber extending in the height direction of the reference plate, a groove provided on the upper side of the sliding chamber, a carrier provided on the lower side of the sliding seat that extends to the inner end of the sliding chamber via the groove, a first roller attached to the lower end of the carrier, the first roller rolling in contact with the bottom of the sliding chamber.

[0012] Preferably, two sets of carriers are provided below the sliding seat, and two of the first rollers are rotatably mounted on each of the carriers.

[0013] Preferably, the upper end of the guide rail is provided with a rectangular opening that communicates with the groove, and the area through which the rectangular opening passes is larger than the projected area of ​​the carrier and the first roller on it.

[0014] Preferably, a second roller is rotatably mounted on the bottom of the sliding seat, which slides against the reference plate. [Effects of the Invention]

[0015] Compared to the conventional technology, the beneficial effects of the present invention are as follows:

[0016] According to the drive mechanism offset type lifting control module of the present invention, the linear drive mechanism and guide member are arranged on both sides, thereby enabling smooth lifting and lowering of the sliding seat with fewer parts. At the same time, the predetermined mounting area in the center of the sliding seat provides sufficient space for designing the massage device. Therefore, offsetting the transmission mechanism provides robust technical assurance for the development of multifunctional massage devices and helps the product to be mounted more thinly and compactly inside the seat backrest. [Brief explanation of the drawing]

[Figure 2] This is a schematic diagram of the structure of the drive mechanism's one-sided lifting control module (when sliding seat B slides to the highest position).

[Figure 4] This is a partial cross-sectional view from a different angle of the drive mechanism's off-center lifting control module. [Figure 5] This is a schematic diagram of the structure of sliding seat B. [Figure 6] This is a reference diagram showing the operating state of the drive mechanism's biased lifting control module. [Modes for carrying out the invention]

[0018] The present invention will be further described below with reference to examples and drawings.

[0019] As shown in FIGS. 1 and 2, the offset type lifting control module with a drive mechanism includes a reference plate A mounted inside the backrest of the seat. A sliding seat B is mounted on the reference plate A, and the sliding seat B is slidable up and down along the height direction of the reference plate A. A guide member D is provided between the right end in the width direction of the sliding seat B and the reference plate A, and a linear drive mechanism C is provided between the left end and the reference plate A. An attachment area B1 for mounting a massage mechanism is provided in the central part of the sliding seat B in advance. Due to the transmission action of the linear drive mechanism C and the guiding and supporting action of the guide member D, the sliding seat B is slidable along the height direction of the reference plate A.

[0020] Based on the design of the above structure, when the offset type lifting control module with a drive mechanism is applied to an automotive seat, as shown in FIG. 6, the reference plate A has a plate-like structure and is mounted inside the backrest E of the seat or is directly part of the backrest skeleton. In the attachment area B1 in the central part of the sliding seat B, a massage device is mounted, which includes a swing arm E1 mounted perpendicular to the height direction of the sliding seat B, a massage head E2 provided at the lower end of the swing arm E1, and a drive member E3 for rotationally driving the swing arm E1. The upper end of the swing arm E1 is rotatably mounted on the sliding seat B. During massage, the drive member E3 rotationally drives the swing arm E1 outward, pushes the massage head E2 forward of the backrest E, and acts on the occupant's lumbar and back. Then, through the lifting control module, the sliding seat B is controlled to move up and down along the reference plate A, that is, the massage head E2 can be moved up and down along the occupant's back, simulating the massage function of running kneading and relaxation. By arranging the linear drive mechanism C and the guide member D on the left and right sides respectively, the smooth up and down movement of the sliding seat B can be realized with fewer components. At the same time, the predetermined attachment area B1 in the central part of the sliding seat B can provide sufficient space for the design of the massage device, having the advantages of reasonable structural arrangement and low cost, and helping the product to be mounted thinner and more compactly inside the backrest of the seat.

[0021] Furthermore, as shown in Fig. 2, the linear drive mechanism C includes a screw C1 fixed to the reference plate A, a nut sleeve C2 fitted onto the screw C1, and a motor C3 for rotationally driving the nut sleeve C2. The motor C3 is fixed to the sliding seat B. The motor C3 rotationally drives the nut sleeve C2, and can helically raise and lower the nut sleeve C2 along the axial direction of the screw C1, that is, the motor C3 and the entire sliding seat B can be synchronously raised and lowered. The advantage of fixing the screw C1 is that it can enhance the support strength and stability of the linear drive mechanism C and ensure the stability of the lifting movement of the sliding seat B. As can be seen from Fig. 2, in this embodiment, both ends of the screw C1 are fixedly supported by the reference plate A via support bases C4.

[0022] As shown in Figs. 1 and 3, the guide member D includes a guide rail D1 fixed to the reference plate A and having a sliding contact chamber D11 extending along the height direction of the reference plate A. A strip groove a is provided on the upper side of the sliding contact chamber D11. Furthermore, as shown in Figs. 4 and 5, a carrier D2 is provided on the lower side of the sliding seat B, that is, on the opposite side of the sliding seat B and the guide rail D1. The carrier D2 can advance into the inner end of the sliding contact chamber D11 through the strip groove a. A first roller D3 is attached to the lower end of the carrier D2, and the first roller D3 is in rolling contact with the bottom of the sliding contact chamber D11. With such a design, the screw C1 is offset, and when the linear drive mechanism C drives the sliding seat B to move up and down, it is easy to generate a rocking gap. Therefore, in accordance with the guide member D on the right end, the rocking gap of the sliding seat B can be absorbed, enhancing the loading capacity of the sliding seat B and the stability of the overall structure, with the advantages of a simple structure, low cost, and good lifting smoothness.

[0023] To improve the smoothness of the sliding of the sliding seat B, as shown in Figs. 3 and 5, two sets of carriers D2 are provided on the lower side of the sliding seat B, and two first rollers D3 are rotatably mounted on each carrier D2. The two first rollers D3 are rotatably mounted on both sides of the carrier D2 respectively.

[0024] As can be seen in Figure 1, the upper end of the guide rail D1 is provided with a rectangular opening b that has a larger passage area than the projected area of ​​the carrier D2 and the first roller D3 above it, and communicates with groove a. Considering this, when assembling the product, the carrier D2 and the first roller D3 at its lower end can be installed into the sliding contact chamber D11 through the rectangular opening b, which has the advantage of making assembly convenient.

[0025] As shown in Figure 5, in this embodiment, multiple sets of second rollers B2 are rotatably mounted on the bottom of the sliding seat B, and each of the second rollers B2 slides against the reference plate A. This design further improves the smoothness of the vertical sliding of the sliding seat B.

[0026] Finally, the above description is merely a preferred embodiment of the present invention, and those skilled in the art can, under the teachings of the present invention, make many similar expressions without departing from the spirit and claims of the invention, and all such modifications fall within the scope of the protection of the present invention.
