Utility Model Content

[0004] The utility model overcomes the shortcomings of the existing technology. Its structural design is reasonable. Compared with the existing technology that directly fixes the casing on the supporting frame, it can prevent the massage device from causing harm to the occupants when the vehicle collides, thereby improving safety. The massage force can also be adjusted to make the massage force softer and improve comfort.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A car massage chair with a suspended massage movement includes a massage movement and a seat with a cushion portion and a backrest portion. A receiving cavity is provided on the back of the backrest portion, a supporting frame is provided in the receiving cavity, and the massage movement is arranged in the receiving cavity. The massage movement includes a casing and a massage mechanism arranged in the casing. The casing is suspended relative to the supporting frame. At least two elastic parts are connected between the casing and the supporting frame. The casing maintains a stable connection with the supporting frame through the elastic parts. The elastic parts can provide elastic buffering for the casing when it is subjected to force.

[0007] By adopting the above technical solution, which connects the support frame and the housing with at least two elastic members, compared to the prior art solution of directly fixing the housing to the support frame, it can provide cushioning in the event of a vehicle collision, effectively preventing the massage device from causing injury to occupants and further improving safety. The elastic members can provide a strong cushioning effect for the housing when subjected to forces in multiple directions, such as front-to-back, left-to-right, and up-and-down.

[0008] Preferably, the elastic member is configured as a spring, a plurality of connecting parts are provided on the housing, and the spring is provided between the connecting parts and the supporting frame.

[0009] By adopting the above technical solution, the elastic member can be a spring, and the springs can be provided in multiple groups, and the multiple groups of springs can be arranged symmetrically, so that the force of the two opposing springs is more stable and balanced, and the entire massage mechanism can provide more stable cushioning when subjected to forces in all directions. Of course, the elastic member can also be a spring or other material with cushioning properties. The connection portion is fixed to or integrated with the housing to achieve a fixed connection between the spring ends.

[0010] Preferably, a first mounting hole is provided on the connecting portion, a second mounting hole is provided on the supporting frame, one end of the spring is connected to the first mounting hole, and the other end of the spring is connected to the second mounting hole.

[0011] By adopting the above technical solution, the spring can specifically be a tension spring with connecting ends at both ends. By fixing the two connecting ends to the first mounting hole and the second mounting hole, the connection and positioning of the housing can be achieved.

[0012] Preferably, the support frame includes two support sections arranged parallel to the length direction of the backrest portion, the housing is arranged between the two support sections, the two side edges of the housing are at the same distance from the two support sections, the connecting parts are evenly spaced on the two side edges along the length direction of the backrest portion, and the spring is arranged between the connecting part and the support sections.

[0013] By adopting the above technical solution, the support frame is specifically in an inverted U shape, and the spring is connected between the support section and the side of the casing. The number of springs connected on both sides of the casing is the same and opposite, that is, the springs on both sides are symmetrical. Specifically, there are three springs on both sides of the casing, which can provide a good cushioning and massaging effect on the back of the human body in the height direction, thereby improving safety and comfort.

[0014] Preferably, the massage mechanism includes a motor device and a knocking arm hingedly arranged in the casing and having massage heads on both sides. At least two knocking arms are provided, and through holes are provided at positions corresponding to the massage heads on the casing and the backrest. The motor device drives the knocking arm to swing, so that the massage heads on both sides of the knocking arm can be alternately extended or retracted from the corresponding through holes, respectively, to achieve alternating knocking massage. When the massage head on one side of the knocking arm extends out of the through hole, the massage head is subjected to external resistance force, driving the knocking arm to swing, so that the massage heads on both sides of the knocking arm are placed inside the through hole and are in a stored state.

[0015] By adopting the above technical solution and setting up such a massage mechanism solution, when a vehicle collides, the human body is subjected to external impact force, and the back of the human body directly acts on the massage head on one side of the knocking arm. The massage head on one side of the knocking arm is subjected to the resistance force of the back of the human body, and the knocking arm will swing, so that the massage heads on both sides of the knocking arm are placed on the inside of the through hole and are in a stored state. The massage heads on both sides of the knocking arm will not cause damage to the human body. The stored state does not necessarily mean that the massage heads are completely stored in the through hole. The end of the massage head can also extend a small distance from the through hole. As long as the distance is a safe distance and will not cause damage to the human body, combined with the buffering effect of the spring, safety can be further improved.

[0016] Preferably, the massage mechanism also includes a hinged seat, a drive shaft and a push rod. The hinged seat is fixedly arranged in the casing, the knocking arm is hingedly arranged on the hinged seat, the drive shaft is rotatably arranged in the casing and is located next to the hinged seat, the output shaft of the motor device drives the drive shaft to rotate through the belt transmission structure, one end of the push rod is connected to the drive shaft, and the other end of the push rod is hingedly cooperated with the knocking arm. The drive shaft drives the push rod to move through the eccentric structure, thereby driving the knocking arm to swing.

[0017] By adopting the above technical solution, the output shaft of the motor device drives the driving shaft to rotate through the belt transmission structure. Compared with the gear transmission, the belt transmission can slip and play a certain protective role. The driving shaft drives the push rod to move through the eccentric structure, and the push rod can drive the knocking arm to swing. During the swinging process of the knocking arm, the massage heads on both sides of the knocking arm alternately extend out of the through hole. When a person sits on the chair frame, the massage head can directly knock on the back of the human body to achieve knocking massage. In addition, the layout of each component is reasonable, which makes the overall thickness of the massage mechanism thinner, and multiple knocking arms are driven by one drive shaft, saving space and motor, and reducing costs.

[0018] Beneficial effects of the utility model:

[0019] The utility model has a reasonable structural design. Compared with the prior art in which the casing is directly fixed on the supporting frame, the utility model can prevent the massage device from causing harm to the occupants when the vehicle collides, thereby improving safety. The massage strength can also be adjusted to make the massage strength softer and improve comfort. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] like Figure 1-7As shown, a car massage chair with a suspended massage movement includes a massage movement 1 and a seat 2 with a cushion portion 21 and a backrest portion 22. A receiving cavity 23 is provided on the back of the backrest portion 22, and a support frame 3 is provided in the receiving cavity 23. The massage movement 1 is arranged in the receiving cavity 23. The massage movement 1 includes a casing 4 and a massage mechanism 5 provided in the casing 4. The casing 4 is suspended relative to the support frame 3. At least two elastic members 6 are connected between the casing 4 and the support frame 3. The casing 4 maintains a stable connection with the support frame 3 through the elastic members 6. The elastic members 6 can provide elastic buffering for the casing 4 when it is subjected to force.

[0030] By adopting the above technical solution, which connects the support frame 3 and the housing 4 with at least two elastic members 6, compared to the prior art solution of directly fixing the housing 4 to the support frame 3, a cushioning effect can be provided in the event of a vehicle collision, effectively preventing the massage device from causing injury to the occupants and further improving safety. The elastic members 6 provide a good cushioning effect for the housing 4 when subjected to forces in multiple directions, such as front-to-back, left-to-right, and up-and-down.

[0031] The elastic member 6 is configured as a spring. Multiple connecting portions 41 are provided on the housing 4, and the springs are disposed between the connecting portions 41 and the support frame 3. The elastic member 6 can be a spring, and multiple sets of springs can be provided. These sets of springs can be symmetrically arranged, ensuring a more stable and balanced force applied by the two opposing springs. This provides a more stable cushioning effect when the massage mechanism 1 is subjected to forces in all directions. Of course, the elastic member 6 can also be a spring sheet or other material with cushioning properties. The connection portion 41, fixed or integral with the housing 4, provides a secure connection to the spring ends.

[0032] Among them, a first mounting hole 42 is provided on the connecting part 41, and a second mounting hole 31 is provided on the supporting frame 3. One end of the spring is connected to the first mounting hole 42, and the other end of the spring is connected to the second mounting hole 31. The spring can specifically be a tension spring with connecting ends at both ends. By fixing the two connecting ends to the first mounting hole 42 and the second mounting hole 31, the connection and positioning of the casing 4 can be achieved.

[0033] The support frame 3 includes two support sections 32 arranged in parallel along the length direction of the backrest portion 22, the casing 4 is arranged between the two support sections 32, and the two side edges 44 of the casing 4 are at the same distance from the two support sections 32. The connecting parts 41 are evenly spaced on the two side edges 44 along the length direction of the backrest portion 22, and the springs are arranged between the connecting parts 41 and the support sections 32. The support frame 3 is specifically in an inverted U shape, and the springs are connected between the support sections 32 and the side edges 44 of the casing 4. The number of springs connected on both sides of the casing 4 is the same and relative, that is, the springs on both sides are symmetrical. Specifically, there are three springs on both sides of the casing 4, which can provide a good buffering and massaging effect on the human back in the height direction, thereby improving safety and comfort.

[0034] In addition, the massage mechanism 5 includes a motor device 51 and a knocking arm 52 hingedly arranged in the casing 4 and having massage heads 53 on both sides. There are at least two knocking arms 52, and the positions corresponding to the massage heads 53 on the casing 4 and the backrest 22 are provided with through holes 43. The motor device 51 drives the knocking arm 52 to swing, so that the massage heads 53 on both sides of the knocking arm 52 can be alternately extended or retracted from the corresponding through holes 43, respectively, to achieve alternating knocking massage. When the massage head 53 on one side of the knocking arm 52 extends out of the position of the through hole 43, the massage head 53 is subjected to the action of external resistance force, driving the knocking arm 52 to swing, so that the massage heads 53 on both sides of the knocking arm 52 are placed on the inner side of the through hole 43 and are in a stored state. With the arrangement of the massage mechanism 5 in this way, when a vehicle collides, the human body is subjected to external impact force, and the back of the human body directly acts on the massage head 53 on one side of the knocking arm 52. The massage head 53 on one side of the knocking arm 52 is subjected to the resistance force of the back of the human body, and the knocking arm 52 will swing, so that the massage heads 53 on both sides of the knocking arm 52 are placed on the inner side of the through hole 43 and are in a stored state. The massage heads 53 on both sides of the knocking arm 52 will not cause damage to the human body. This stored state does not necessarily mean that the massage heads 53 are completely stored in the through hole 43. The end of the massage head 53 can also extend a small distance from the through hole 43, as long as the distance is a safe distance and will not cause damage to the human body. In this way, combined with the buffering effect of the spring, safety can be further improved.

[0035] In addition, the massage mechanism 5 also includes a hinged seat 54, a drive shaft 55 and a push rod 56. The hinged seat 54 is fixedly arranged in the casing 4, the knocking arm 52 is hingedly arranged on the hinged seat 54, the drive shaft 55 is rotatably arranged in the casing 4 and is located next to the hinged seat 54, the output shaft of the motor device 51 drives the drive shaft 55 to rotate through the belt transmission structure 57, one end of the push rod 56 is connected to the drive shaft 55, and the other end of the push rod 56 is hingedly cooperated with the knocking arm 52, and the drive shaft 55 drives the push rod 56 to move through the eccentric structure 58, thereby driving the knocking arm 52 to swing. With such an arrangement, the output shaft of the motor device 51 drives the driving shaft 55 to rotate via the belt transmission structure 57. Compared with the gear transmission, the belt transmission can slip and play a certain protective role. The driving shaft 55 drives the push rod 56 to move through the eccentric structure 58. The push rod 56 can drive the knocking arm 52 to swing. During the swinging process of the knocking arm 52, the massage heads 53 on both sides of the knocking arm 52 alternately extend out of the through hole 43. When a person sits on the chair frame, the massage head 53 can directly knock on the back of the human body to achieve knocking massage. In addition, the layout of each component is reasonable, so that the overall thickness of the massage mechanism 5 is thinner, and multiple knocking arms 52 are driven by a driving shaft 55, which saves space and motors and reduces costs.

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
