Description

Technical Field

[0001] The utility model relates to the technical field of automobile seat massage, in particular to a lifting control module with an offset driving mechanism. Background Art

[0002] With the progress of technology, people's requirements for the comfort of automobile seats are also constantly improving. For occupants who drive and 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. To solve the fatigue problems derived from long-term driving and riding, more and more seats are beginning to be equipped with massage functions.

[0003] In the prior art, the massagers on automobile seats are divided into two categories: airbag massage and mechanical massage. Among them, the airbag massage uses soft airbags to act on the user's back and waist area, with a relatively low massage intensity and poor massage effect, and it is difficult to relax the user's body comprehensively and deeply. Most mechanical massage devices directly massage the user's back through a rotatable massage device, and the massage method is relatively single. It is difficult to comprehensively simulate the kneading, knocking, and pushing techniques that manual massage can provide, and the comfort experience urgently needs to be improved.

[0004] Therefore, the applicant intends to develop a new mechanical multi-functional massage device, aiming to simulate functions such as fixed-point kneading, walking kneading, fixed-point knocking, walking knocking, and pushing, so that the seat back can provide more realistic manual massage techniques. In this research and development context, walking kneading, walking knocking, and pushing all require the massage execution element to reciprocate along the height direction of the backrest. Since the design space inside the automobile seat backrest is relatively limited, and in addition, it is necessary to meet functions such as kneading, knocking, and pushing, so how to layout and install the lifting control mechanism of the massage device in this case has become a technical problem to be solved urgently. Summary of the Utility Model

[0005] In view of this, the utility model provides a lifting control module with an offset driving mechanism, which has the advantages of reasonable layout and good smoothness.

An installation area is preset in the middle of the sliding seat for integrally installing a massage mechanism; under the driving action of the linear driving mechanism and the guiding and supporting action of the guiding component, the sliding seat can slide along the height direction of the reference plate.

[0008] With the above structure, by arranging the linear drive mechanism and the guiding component on both sides respectively, the smooth lifting movement of the sliding seat can be achieved with fewer components. At the same time, the installation area reserved in the middle of the sliding seat can provide sufficient space for the design of the massage device.

[0009] Preferably, the linear drive mechanism includes a lead screw fixedly arranged on the reference plate, a nut sleeve sleeved on the lead screw, and a motor for driving the nut sleeve to rotate.

[0023] The present utility model will be further described below in conjunction with embodiments and the drawings.

[0024] As Figure 1 and 2 shown, an offset type lifting control module of a driving mechanism includes a reference plate A, which is used to be installed inside the seat backrest. A sliding seat B is installed on the reference plate A, and the sliding seat B can slide up and down along the height direction of the reference plate A. A guiding component D is provided between the right end of the sliding seat B in the width direction and the reference plate A, and a linear driving mechanism C is provided between the left end of the sliding seat B and the reference plate A. An installation area B1 is preset in the middle of the sliding seat B, and this installation area B1 is used for integrally installing a massage mechanism. Under the driving action of the linear driving mechanism C and the guiding and supporting action of the guiding component D, the sliding seat B can slide along the height direction of the reference plate A.

[0025] Based on the above structural design, when the offset type lifting control module of the driving mechanism is applied to an automobile seat, referring to Figure 6 , the reference plate A is a plate-shaped structure, which is installed inside the backrest E of the seat, or directly is a part of the backrest frame. A massage device is installed on the installation area B1 in the middle of the sliding seat B. The massage device includes a swing arm E1 vertically installed along the height direction of the sliding seat B, a massage head E2 arranged at the lower end of the swing arm E1, and a driving component E3 for driving the swing arm E1 to rotate. The upper end of the swing arm E1 is rotatably installed on the sliding seat B. During massage, the driving component E3 drives the swing arm E1 to rotate outwards, so that the massage head E2 can protrude towards the front side of the backrest E and act on the back and waist of the occupant. Then, the sliding seat B is controlled to move up and down along the reference plate A through the lifting control module, that is, the massage head E2 can be driven to move up and down along the back of the occupant, so as to simulate the massage function of walking and massaging. By arranging the linear driving mechanism C and the guiding component D on the left and right sides respectively, the sliding seat B can be made to move up and down smoothly with fewer components. At the same time, the reserved installation area B1 in the middle of the sliding seat B can provide sufficient space for the design of the massage device, having the advantages of reasonable structural layout and low cost, and helping the product to be integrated inside the seat backrest in a thinner and more compact manner.

[0026] For another example Figure 2 As shown, the linear drive mechanism C includes a lead screw C1 fixedly arranged on the reference plate A, a nut sleeve C2 sleeved on the lead screw C1, and a motor C3 for driving the nut sleeve C2 to rotate. The motor C3 is fixedly installed on the slide B. When the motor C3 drives the nut sleeve C2 to rotate, it can drive the nut sleeve C2 to perform a helical lifting and lowering movement along the axial direction of the lead screw C1, that is, it can synchronously drive the motor C3 and the slide B as a whole to perform a lifting and lowering movement. The advantage of fixedly arranging the lead screw C1 is that it can improve the support strength and stability of the linear drive mechanism C, thereby ensuring the stability of the lifting movement of the slide B. From Figure 2 it can be seen that in this embodiment, both ends of the lead screw C1 are fixedly supported on the reference plate A through supports C4.

[0027] Please refer Figure 1 and 3 , the guiding component D includes a guide rail D1 fixedly arranged on the reference plate A. The guide rail D1 has a sliding cavity D11 extending along the height direction of the reference plate A, and a strip-shaped groove a is provided on the upper side of the sliding cavity D11. Combining with Figure 4 and 5 as shown, a wheel frame D2 is provided on the lower side of the slide B, that is, on the side of the slide B opposite to the guide rail D1. The wheel frame D2 can pass through the strip-shaped groove a and extend into the inner end of the sliding cavity D11. A first roller D3 is installed at the lower end of the wheel frame D2, and the first roller D3 is in rolling contact with the bottom of the sliding cavity D11. With such a design, since the lead screw C1 is arranged offset, when the linear drive mechanism C drives the slide B to lift and lower, there is easily a shaking gap. Therefore, in cooperation with the guiding component D at the right end, it can absorb the shaking gap of the slide B, improve the load-bearing capacity of the slide B and the stability of the overall structure, and has the advantages of simple structure, low cost, and good lifting smoothness.

[0028] To improve the smoothness of the sliding of the slide B, referring again to Figure 3 and Figure 5 , two groups of wheel frames D2 are provided on the lower side of the slide B, and two first rollers D3 are rotatably installed on each wheel frame D2, and the two first rollers D3 are respectively rotatably installed on both sides of the wheel frame D2.

[0029] From Figure 1 it can be seen that a rectangular opening b communicating with the strip-shaped groove a is provided at the upper end of the guide rail D1, and the passing area of the rectangular opening b is larger than the projected area of the wheel frame D2 and the first roller D3 thereon. Considering this way, during product assembly, the wheel frame D2 and the first roller D3 at its lower end can be installed into the sliding cavity D11 through the rectangular opening b, which has the advantage of convenient assembly.

[0030] For example Figure 5 as shown, in this embodiment, multiple groups of second rollers B2 are rotatably assembled at the bottom of the slide B, and each second roller B2 is in sliding contact with the reference plate A. With such a design, it can further improve the smoothness of the lifting and sliding of the slide B.

[0031] Finally, it should be noted that the above description is only the preferred embodiment of the present utility model. Those of ordinary skill in the art can make various similar representations under the inspiration of the present utility model without violating the purpose and claims of the present utility model. Such transformations all fall within the protection scope of the present utility model.
