[0001] This utility model relates to the field of massage mechanism technology, specifically to a buttock massage mechanism for the seat cushion of a car seat. Background Technology

[0002] The automotive industry is developing rapidly, making progress not only in vehicle speed and energy consumption, but also in the diversification of in-car functions to provide a better riding experience for drivers and passengers. As a result, many cars now have massage mechanisms installed inside the seats.

[0003] The massage mechanism of a car seat is divided into two parts: one part is located in the seat cushion and the other part is located in the backrest. The massage structure in the seat cushion is mainly used to massage the buttocks of passengers who have been sitting for a long time, such as a seat with a massage seat cushion disclosed in the prior art with the publication number CN209257943U.

[0004] Massage devices are typically hidden within the metal frame of a car, massaging the passenger's buttocks from bottom to top. However, existing massage devices have a small stroke and limited contact area with the passenger's body, resulting in a small massage range. Utility Model Content

[0005] The purpose of this invention is to provide a buttock massage mechanism for a car seat cushion. By driving two pressing components to reciprocate along an arc-shaped trajectory, the travel of the roller swinging back and forth is increased, the contact area with the passenger's buttocks is wider, and the massage range is expanded.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a buttock massage mechanism for a car seat cushion, comprising a bracket with two upright plates, a dual-axis motor and a drive shaft on the bracket, the dual-axis motor being fixedly mounted on the top of the bracket and located between the two upright plates, the two ends of the drive shaft passing through the two upright plates and being rotatably connected to the upright plates, and both ends of the drive shaft being provided with telescopic components;

[0007] The telescopic component is equipped with a mounting plate via a four-bar linkage. The mounting plate is equipped with a pressing component. The pressing component includes a central shaft that passes through the mounting plate and is rotatably connected to the mounting plate. Two rollers are fixedly mounted on the outer end of the central shaft. The two rollers are located on both sides of the mounting plate. The rollers press on the surface of the human buttocks, which can cause the pressing area to be indented by up to 20mm. The indentation depth is proportional to the massage force.

[0008] Furthermore, two cylinders are provided on both the front and rear sides of the bracket. A connecting plate is fixedly provided at the top of the cylinder, and a pull rod is fixedly provided at the bottom of the connecting plate. The bottom of the pull rod is fixedly connected to the top of the bracket. The height of the bracket and the massage mechanism as a whole is adjusted by extending and retracting the cylinders, thereby adjusting the massage intensity.

[0009] Furthermore, each of the two output shafts of the dual-axis motor is fixedly equipped with a drive gear, and the outer end of the drive shaft is fixedly equipped with two driven gears, with the two drive gears meshing with the two driven gears respectively.

[0010] Furthermore, two electromagnets are fixedly installed on the bracket, and the two electromagnets are respectively fixed on the two upright plates of the bracket, and the two electromagnets correspond to the two telescopic components respectively;

[0011] The telescopic assembly includes a sleeve fixedly disposed at one end of the drive shaft. A return spring is fixedly disposed on the inner wall of the sleeve. A guide rod is fixedly disposed at one end of the return spring. The cross-section of the guide rod is rectangular. The end of the guide rod away from the drive shaft extends to the outside of the sleeve and is fixedly disposed on an end rod. The end rod is cylindrical. An iron baffle is fixedly disposed at the outer end of the end rod.

[0012] Furthermore, a connecting rod is fixedly provided at the end of the iron baffle away from the drive shaft, and a connecting rod is rotatably connected at the end of the connecting rod away from the iron baffle.

[0013] Link 1 has a second link on the side facing the drive shaft. One end of the second link is sleeved on the outer end of the iron baffle and rotatably connected to the iron baffle. The other end of the second link is rotatably connected to the fourth link. The connection between the second link and the fourth link is located at the bottom end of the fourth link. The end of the third link away from the first link is rotatably connected to the fourth link. The connection between the third link and the fourth link is located in the middle of the fourth link.

[0014] Furthermore, the top end of the fourth connecting rod is rotatably connected to the bottom end of the mounting plate, and buffer springs are provided on both sides of the mounting plate. End plates are fixedly provided at both ends of the buffer springs, and the two end plates are fixedly connected to the mounting plate and the fourth connecting rod, respectively.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. The mounting plate and pressing components are driven by the drive shaft and four-bar linkage. The two pressing components reciprocate along an arc trajectory under the drive, causing the roller to roll on the passenger's buttocks, thereby achieving the purpose of massage.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] This utility model provides, for example Figure 1-6The illustrated car seat cushion buttock massage mechanism includes a bracket 5, on which a dual-axis motor 1 and a drive shaft 3 are mounted. The dual-axis motor 1 is fixedly mounted on the top of the bracket 5 and located between two upright plates of the bracket 5. The two ends of the drive shaft 3 pass through the two upright plates and are rotatably connected to the upright plates. Both ends of the drive shaft 3 are provided with telescopic components 8. The two output shafts of the dual-axis motor 1 are each fixedly provided with a drive gear 2. The outer end of the drive shaft 3 is fixedly provided with two driven gears 4, and the two drive gears 2 mesh with the two driven gears 4 respectively.

[0029] The support 5 is equipped with two cylinders 9 on both the front and rear sides. A connecting plate is fixedly provided at the top of the cylinder 9, and a pull rod 10 is fixedly provided at the bottom of the connecting plate. The bottom of the pull rod 10 is fixedly connected to the top of the support 5. The height of the support 5 and the massage mechanism as a whole is adjusted by extending and retracting the cylinders 9, thereby adjusting the massage intensity.

[0030] The massage mechanism is hidden in the frame of the car seat. It is driven by a dual-axis motor 1 to rotate the drive gear 2, which in turn drives the driven gear 4 and the drive shaft 3 to rotate, thereby driving the corresponding components to massage the passenger's buttocks. The top of the cylinder 9 is connected to the bracket 5 through the pull rod 10. The cylinder 9 can thus adjust the height of the bracket 5 and the entire massage mechanism by extending and retracting, thereby adjusting the massage intensity and making the massage mechanism more versatile.

[0031] In order to massage the passenger's buttocks, such as Figure 1 , Figure 4 As shown, the telescopic component 8 is equipped with a mounting plate 12 via a four-link 6. The mounting plate 12 is equipped with a pressing component 7. The pressing component 7 includes a central shaft 701 that passes through the mounting plate 12 and is rotatably connected to the mounting plate 12. Two rollers 702 are fixedly mounted on the outer end of the central shaft 701. The two rollers 702 are located on both sides of the mounting plate 12. The rollers 702 press on the surface of the human buttocks, which can cause the pressing area to be recessed by up to 20mm. The recess depth is proportional to the massage force. The telescopic movement of the cylinder 9 is used to adjust the massage force within a range of 20mm.

[0032] After the drive shaft 3 rotates, the drive shaft 3 drives the mounting plate 12 and the pressing component 7 through the telescopic component 8 and the four-link 6. The two pressing components 7 reciprocate along an arc-shaped trajectory under the drive. During the movement, the pressing component 7 moves upward as a whole, pushing and squeezing the buttock muscles. At the same time, the pressing component 7 moves back and forth, causing the roller 702 to roll on the passenger's buttocks, thereby achieving the purpose of massage. This driving method makes the roller 702 swing back and forth with a larger stroke and a wider contact area with the passenger's buttocks, thus increasing the massage range.

[0033] During the massage, the massage area can be adjusted as needed, such as... Figure 1 , Figure 2 , Figure 5 , Figure 6 As shown, two electromagnets 14 are fixedly mounted on the bracket 5. The two electromagnets 14 are respectively fixed on the two upright plates of the bracket 5, and the two electromagnets 14 correspond to the two telescopic components 8 respectively.

[0034] The telescopic assembly 8 includes a sleeve 801 fixedly disposed at one end of the drive shaft 3. A return spring 805 is fixedly disposed on the inner wall of the sleeve 801. A guide rod 802 is fixedly disposed at one end of the return spring 805. The cross-section of the guide rod 802 is rectangular. The end of the guide rod 802 away from the drive shaft 3 extends to the outside of the sleeve 801 and is fixedly disposed on an end rod 803. The end rod 803 is cylindrical. An iron baffle 804 is fixedly disposed at the outer end of the end rod 803.

[0035] Before the massage, the electromagnet 14 can be energized. Under the action of the magnetic force, the electromagnet 14 will attract the iron baffle 804 and drive the guide rod 802 and the end rod 803. The guide rod 802 will retract into the sleeve 801. During the retraction, the return spring 805 will be compressed. The retraction of the end rod 803 will cause the four-link 6 and the pressing component 7 to move laterally, thereby adjusting the position of the pressing component 7 and thus adjusting the massage position. The strength of the magnetic force of the electromagnet 14 can be controlled, thereby controlling the degree of retraction of the guide rod 802. This allows for flexible control of the position of the pressing component 7, making the massage area more extensive. It can also adapt to different people's hip sizes by adjusting the massage position, making the massage mechanism more widely applicable.

[0036] The massage trajectory is an arc, such as... Figure 1 , Figure 3 As shown, a connecting rod 601 is fixedly provided at one end of the iron baffle 804 away from the drive shaft 3, and a connecting rod 603 is rotatably connected at the other end of the connecting rod 601 away from the iron baffle 804.

[0037] Link 1 601 is provided with link 2 602 on the side facing the drive shaft 3. One end of link 2 602 is sleeved on the outer end of the iron baffle 804 and rotatably connected to the iron baffle 804. The other end of link 2 602 is rotatably connected to link 4 604. The connection part between link 2 602 and link 4 604 is located at the bottom end of link 4 604. The end of link 3 603 away from link 1 601 is rotatably connected to link 4 604. The connection part between link 3 603 and link 4 604 is located in the middle part of link 4 604.

[0038] The telescopic component 8 drives the first link 601 and the third link 603 to rotate, which in turn drives the fourth link 604 and the mounting plate 12 to swing. The second link 602 keeps the fourth link 604 stable during rotation, driving the pressing component 7 to reciprocate along the arc.

[0039] To act as a buffer, such as Figure 3 , Figure 4 As shown, the top end of the connecting rod 604 is rotatably connected to the bottom end of the mounting plate 12. A bracket is fixedly provided at the top end of the connecting rod 604, and the bottom end of the mounting plate 12 is rotatably connected to the inner wall of the bracket. Both sides of the mounting plate 12 are provided with buffer springs 11, and both ends of the buffer springs 11 are fixedly provided with end plates 13. The two end plates 13 are fixedly connected to the mounting plate 12 and the connecting rod 604 respectively.

[0040] Although the mounting plate 12 and the fourth link 604 are not a single unit, they are connected to each other by a buffer spring 11. Therefore, the mounting plate 12 can move synchronously with the fourth link 604. However, during the massage, while the pressing component 7 applies force to the buttocks, the reaction force also acts on the pressing component 7 and the mounting plate 12. This causes the mounting plate 12 to rotate slightly relative to the fourth link 604. The rotation causes the buffer spring 11 to bend and generate elastic force. The elastic force of the buffer spring 11 is used to buffer the reaction force and prevent the reaction force from causing the mounting plate 12 or the fourth link 604 to break.

[0041] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
