Description

Technical Field

[0001] This utility model relates to the field of massage device technology, and in particular to a massage device and a car seat. Background Technology

[0002] With the increasing number of cars on the road and people's growing demands for quality of life, the comfort of car seats is receiving more and more attention from consumers and manufacturers. More and more car seats are incorporating massage functions to provide a comfortable experience and relieve travel fatigue during long journeys. Currently, most mainstream car seats on the market use airbag massage. However, airbag massage has drawbacks: its movements are limited, inflation and deflation times are long, and its rigidity is relatively poor, failing to achieve the effects of a mechanical massage mechanism. Furthermore, in the event of a significant impact, the airbag may not deflate promptly, posing a risk of injury to the user. Utility Model Content

[0003] This utility model provides a massage device and a car seat that combines a traditional mechanical massage device with an airbag massage device. In addition, the airbag can be deflated in time when impacted to ensure user safety.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A massage device includes a housing, within which a drive assembly is disposed. The drive assembly includes a transmission member and a drive device for driving the transmission member to rotate. The transmission member is provided with a sliding groove disposed along its axial direction. The device also includes...

[0006] A connecting shaft has a massage head connected to one end and a slide groove connected to the other end. The other end of the connecting shaft is configured to be movable along the axial direction of the slide groove and is circumferentially limited and connected to the slide groove. The massage head is driven to rotate by a driving device.

[0007] The lifting assembly includes an air pump connected to an air bladder via an air passage. The air bladder is sleeved on the outside of the connecting shaft, with one end abutting against the housing and the other end acting on the connecting shaft. The inflation and deflation of the air bladder controls the raising and lowering of the massage head.

[0008] A venting assembly is used to monitor the air pressure in the air passage to control whether the air passage is connected to the atmospheric environment.

[0009] Furthermore, the venting assembly includes a controller and a pressure sensor and a valve electrically connected to the controller. The controller opens and closes the valve based on the pressure in the air path monitored by the pressure sensor, thereby controlling whether the air path is connected to the atmospheric environment.

[0010] Furthermore, the air circuit is provided with a three-way adapter, the air outlet of the air pump is connected to one of the interfaces of the three-way adapter, the second interface of the three-way adapter is connected to the air pressure sensor, and the third interface of the three-way adapter is connected to the airbag.

[0011] Furthermore, a buffer support is provided on the outer side of the housing.

[0012] Furthermore, the outer side of the connecting shaft forms a first abutting surface, and the inner side of the sliding groove forms a second abutting surface. When the connecting shaft rotates, the first abutting surface and the second abutting surface abut against each other to form a circumferential limiting fit.

[0013] Furthermore, the end of the connecting shaft near the massage head is provided with a first limiting part, and the end of the connecting shaft away from the massage head is provided with a second limiting part. The minimum radial dimension of the first limiting part and the second limiting part is greater than the maximum radial dimension of the slide groove.

[0014] Furthermore, a spring is fitted onto the end of the connecting shaft away from the massage head, with one end of the spring abutting against the second limiting part and the other end of the spring abutting against the transmission member.

[0015] Furthermore, it also includes a bearing, which overlaps the first limiting part, and the bearing is fitted with a bearing seat, with the other end of the airbag connected to the bearing seat.

[0016] Furthermore, a transition member is provided between the drive device and the transmission component, and the transition member is tractively connected to the drive device and the transmission component.

[0017] A car seat includes a backrest and a massage device as described above. The backrest has clearance for movement of the massage head and a fixing module to which the cushioning support is connected.

[0018] The beneficial effects of this utility model are:

[0019] 1. This utility model proposes a massage device with an inflatable and deflated airbag between a drive assembly and a massage head. A connecting shaft passes through the airbag, with one end connected to the massage head and the other end circumferentially limited and connected to the drive assembly. In use, the massage head can be rotated by the drive assembly, and the inflation and deflation of the airbag can control the raising and lowering of the massage head. While maintaining the high comfort of the airbag massage device and easily meeting the collision safety requirements of car seats, the massage head acts on the user's back, improving the problem of poor rigidity of the airbag massage device. At the same time, the deflation assembly monitors the air pressure in the air circuit. When the airbag is compressed by an external device, causing the pressure in the air circuit to increase to a preset value, the deflation assembly controls the air circuit to connect to the atmospheric environment, allowing the airbag to deflate quickly and ensuring user safety.

[0020] 2. The massage device proposed in this utility model has a buffer support on the outside of the shell, which further meets the collision safety requirements of car seats.

[0021] 3. The massage device proposed in this utility model has an outer side of the connecting shaft forming a first contact surface and an inner side of the slide groove forming a second contact surface. When the airbag is inflated to control the connecting shaft to extend to any length, rotating the connecting shaft can make the first contact surface and the second contact surface form a circumferential limiting fit, which makes it convenient for the user to control the distance of the massage head extension.

[0022] 4. The massage device proposed in this utility model has a first limiting part and a second limiting part at both ends of the connecting shaft. The minimum radial dimension of the first limiting part and the second limiting part is greater than the maximum radial dimension of the slide groove, so as to prevent the connecting shaft from extending too far and causing the connecting shaft to disengage from the slide groove, and to prevent the connecting shaft from retracting too far and causing excessive compression to the airbag.

[0023] 5. The massage device proposed in this utility model has a spring sleeve on the connecting shaft, with one end abutting against the second limiting part and the other end abutting against the transmission component; when the airbag deflates, the elastic force generated by the spring can accelerate the reset speed of the massage head.

[0024] 6. The massage device proposed in this utility model also includes a bearing, which is connected to the first limiting part. The bearing is fitted with a bearing seat, and the airbag is connected to the bearing seat. When the connecting shaft rotates, the bearing seat is stationary to prevent the airbag from rotating with the connecting shaft and to prevent the air passage from getting tangled.

[0025] 7. The massage device proposed in this utility model is provided with a transition component between the driving device and the transmission component. The transition component is connected to the driving device and the transmission component. Different specifications of transition components can be configured according to the usage requirements to realize the transmission ratio between the driving device, the transition component and the transmission component.

[0026] 8. The present invention proposes a massage device, including a back frame and a massage device as described above. The back frame is provided with clearance space for the movement of the massage head, and the massage device is connected to a fixed module through a buffer support. The overall modularity is high, and it requires less modification to existing vehicle seats, making it easy to promote and use. Attached Figure Description

Detailed Implementation

[0037] Example 1

[0038] A massage device includes a housing, within which a drive assembly is disposed. The drive assembly includes a transmission member 301 and a drive device 302 for rotating the transmission member 301. The transmission member 301 is provided with a slide groove 3011 arranged along its axial direction. The device also includes...

[0039] A connecting shaft 40 is connected to a massage head 50 at one end and to a slide groove 3011 at the other end. The other end of the connecting shaft 40 is configured to be axially movable along the slide groove 3011 and is circumferentially limited and connected to the slide groove 3011.

[0040] The lifting assembly includes an air pump connected to an airbag 60 via an air passage, the airbag 60 being sleeved on the outside of the connecting shaft 40, one end of the airbag 60 abutting against the housing, and the other end of the airbag 60 acting on the connecting shaft 40; and a deflation assembly for monitoring the air pressure in the air passage to control whether the air passage is connected to the atmospheric environment.

[0041] In use, the massage head 50 is driven to rotate by the drive device 302, and the inflation and deflation of the airbag 60 controls the raising and lowering of the massage head 50. Therefore, while maintaining the high comfort level of the airbag 60 massage device and easily meeting the collision safety requirements of car seats, the massage head 50 is positioned to act on the user's back, improving the problem of poor rigidity in the airbag 60 massage device. Simultaneously, the deflation component monitors the air pressure in the air passage. When the airbag 60 is compressed due to external forces, causing the pressure in the air passage to increase to a preset value, the deflation component connects the air passage to the atmospheric environment, allowing the airbag 60 to deflate rapidly, ensuring user safety.

[0042] In this embodiment, the venting assembly includes a controller, a pressure sensor 70, and a valve electrically connected to the controller. The controller opens and closes the valve based on the pressure in the air path monitored by the pressure sensor 70, thereby controlling whether the air path is connected to the atmospheric environment. Further, as... Figure 6 As shown, a three-way adapter 80 is provided in the air circuit. The air outlet of the air pump is connected to one of the interfaces of the three-way adapter 80, the second interface of the three-way adapter 80 is connected to the air pressure sensor 70, and the third interface of the three-way adapter 80 is connected to the airbag 60. In other embodiments, a one-way valve that opens in the direction of air release can also be provided in the air circuit. If the air pressure is higher than the opening pressure of the one-way valve, the one-way valve opens to release air from the airbag 60; if the air pressure is lower than the opening pressure of the one-way valve, the one-way valve is closed.

[0043] like Figures 1 to 3As shown, the driving device 302 is a drive motor with dual output ends. The output ends of the motor are integrally formed or equipped with a worm gear. The transmission component 301 is provided with a worm wheel adapted to the worm gear, thereby realizing the rotation of two massage heads 50 through one drive motor. This results in low cost and a more compact overall structure. Simultaneously, each of the two massage heads 50 is equipped with an airbag 60. The two airbags 60 can be inflated and deflated simultaneously, or they can be inflated and deflated separately, allowing the two massage heads 50 to be ejected at different times, providing a better massage experience. In other embodiments, such as... Figure 4 As shown, the number of massage heads 50 can also be four to provide a larger massage area and more massage modes.

[0044] In this embodiment, as Figure 3 As shown, a buffer support 90 is provided on the outer side of the housing to further meet the collision safety requirements of the car seat. The buffer support 90 is made of steel wire, which has good support performance and good toughness. The buffer support 90 is fastened to the housing by fasteners, or it can be connected by welding or other methods.

[0045] In this embodiment, the outer surface of the connecting shaft 40 forms the first abutment surface 1001, and the inner surface of the slide groove 3011 forms the second abutment surface 1002. The horizontal cross-sections of the first abutment surface 1001 and the second abutment surface 1002 are non-circular, thus forming a circumferential limiting fit between the first abutment surface 1001 and the second abutment surface 1002. Specifically, as shown... Figure 3 As shown, the connecting shaft 40 has a first plane on each of its opposite outer sides, and the sliding groove 3011 has a second plane on each of its opposite inner sides. The first planes form a first abutment surface 1001, and the second planes form a second abutment surface 1002. In use, the connecting shaft 40 can be extended to any length by inflating the airbag 60, ensuring that the first abutment surface 1001 and the second abutment surface 1002 form a circumferential limiting fit, facilitating user operation.

[0046] In this embodiment, as Figure 2 As shown, the connecting shaft 40 has a first limiting part 401 at the end near the massage head 50 and a second limiting part 402 at the end away from the massage head 50. The minimum radial dimension of the first limiting part 401 and the second limiting part 402 is greater than the maximum radial dimension of the slide groove 3011. The second limiting part 402 is used to prevent the connecting shaft 40 from over-extending and causing it to disengage from the slide groove 3011. The first limiting part 401 is used to prevent the connecting shaft 40 from over-retracting and causing excessive compression to the airbag 60. The first limiting part 401 is integrally formed on the shoulder of the connecting shaft 40, and the second limiting part 402 is a limiting piece connected to the connecting shaft 40.

[0047] In this embodiment, as Figure 2As shown, the transmission component 301 is provided with a receiving groove 3012, which is connected to the slide groove 3011. The second limiting part 402 is located in the receiving groove 3012, which reduces or avoids the end of the connecting shaft 40 away from the massage head 50 protruding from the transmission component 301, reduces the overall size, and reduces the installation space requirements of this device.

[0048] In this embodiment, as Figure 2 As shown, a spring 110 is fitted onto the portion of the connecting shaft 40 located in the receiving groove 3012. One end of the spring 110 abuts against the second limiting part 402, and the other end of the spring 110 abuts against the transmission member 301. When the airbag 60 deflates, the elastic force generated by the spring 110 can accelerate the reset speed of the massage head 50.

[0049] In this embodiment, as Figure 3 As shown, it also includes a bearing 120, which overlaps the first limiting part 401. A bearing housing 120 is provided around the bearing 120, and the other end of the airbag 60 abuts against the bearing housing 120. Locking plates are provided at both ends of the airbag 60, and the locking plates are respectively connected to the housing and the bearing housing 120. When the connecting shaft 40 rotates, the inner ring of the bearing 120 rotates, while the outer ring of the bearing 120 remains stationary, thus keeping the bearing housing 120 stationary as well. This prevents the airbag 60 from rotating with the connecting shaft 40 and prevents air entanglement.

[0050] In this embodiment, as Figure 3 As shown, a transition piece 140 is also provided between the drive device 302 and the transmission component 301. The transition piece 140 is connected to the drive device 302 and the transmission component 301. Different specifications of the transition piece 140 can be configured according to the usage requirements to realize the transmission ratio between the drive device 302, the transition piece 140 and the transmission component 301.

[0051] Example 2

[0052] A type of car seat, such as Figures 5-8 As shown, the seat includes a backrest 150 and a massage device as described above. The backrest 150 has clearance space for the movement of the massage head 50. The backrest 150 has a fixing module 160, which is made of steel wire. A buffer support 90 is connected to the fixing module 160 to improve the safety performance of the car seat. This car seat has a high degree of modularity, requires minimal modification to existing vehicle seats, and is easy to promote and use.

They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the scope of protection of this utility model.
