DETAILED DESCRIPTION

[0057] The core of the utility model is to provide a neck and waist massage pad so that the headrest massage movement can meet the needs of users of different heights.

[0058] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0059] like Figure 1 and Figure 2 As shown, the embodiment of the utility model discloses a cervical and lumbar massage pad, which can be placed on a chair to massage the user. For example, it can be applied to office chairs, car seats, etc., and the cervical and lumbar massage pad does not occupy much space on the chair, and does not significantly affect the user's riding space.

[0060] The neck and waist massage cushion comprises a seat cushion 200, a back cushion 100, a headrest massage device 300 and a waist and back massage device 400. The headrest massage device 300 is arranged on the back cushion 100. Since the headrest massage device 300 is used for massaging the head and neck, it needs to be placed at a higher position of the back cushion 100.

[0061] like Figure 4 As shown, the headrest massage device 300 includes a headrest pad 310 and a headrest massage component arranged on the headrest pad 310. The headrest pad 310 should have a certain thickness to provide sufficient and effective support for the user. The headrest pad 310 can be made of materials such as sponge and silica gel that can provide cushioning and support effects for the user. A headrest adjustment belt 311 is provided on the headrest pad 310, and a headrest connector 103 for connecting different positions of the headrest adjustment belt 311 is provided on the back side of the backrest pad 100. One end of the headrest adjustment belt 311 is connected to the headrest pad 310, and the other end passes around the top of the backrest pad 100, and passes around to the back side of the backrest pad 100 and is connected and fixed to the headrest connector 103.

[0062] For details, please combine Figure 6 As shown, the headrest adjustment belt 311 may be provided with adjustment connectors 313 arranged at intervals in the height direction, that is, the adjustment connectors 313 are provided along the extension direction of the headrest adjustment belt 311, and the headrest connector 103 is used to connect with the adjustment connectors 313 at different height positions (that is, different distance positions from the headrest pad 310) to adjust the height of the headrest massage device 300. That is, the closer the headrest connector 103 is to the position where the adjustment connector 313 is connected to the headrest pad 310, the higher the height of the headrest pad 310 is; correspondingly, the farther the headrest connector 103 is from the position where the adjustment connector 313 is connected to the headrest pad 310, the lower the height of the headrest pad 310 is.

[0063] Accordingly, the adjustment connector 313 and the headrest connector 103 can both be Velcro, and the adjustment connector 313 needs to have a certain length to make the adjustment range larger. The adjustment connector 313 and the headrest connector 103 can also be snap buckles, and the adjustment connector 313 needs to be provided with multiple snap buckles in the extension direction of the headrest adjustment belt 311 to ensure a certain height adjustment range.

[0064] The waist and back massage device 400 is disposed on the backrest cushion 100, and the headrest massage device 300 is located above the waist and back massage device 400. The waist and back massage device 400 is used to perform a relaxing massage on the waist and back of the user.

[0065] The cervical and lumbar massage pad provided by the utility model detachably connects the headrest massage device 300 with the back cushion 100, and a headrest adjustment belt 311 is arranged on the headrest pad 310, and a headrest connector 103 for connecting different positions of the headrest adjustment belt 311 is arranged on the rear side of the back cushion 100. By connecting different positions of the headrest adjustment belt 311 with the headrest connector 103, the position of the headrest massage device 300 on the height of the back cushion 100 can be adjusted, so that the user can adjust the height of the headrest massage device 300 according to the height, thereby meeting the user's demand for the position of the headrest massage device 300.

[0066] like Figure 4 As shown, the headrest pad 310 is provided with a headrest portion embedding groove 312 for embedding the headrest portion massage component, so as to prevent the headrest portion massage component from protruding too much from the headrest pad 310 and affecting comfort. In addition, the headrest portion embedding groove 312 can also ensure the installation stability of the headrest portion massage component and prevent the headrest portion massage component from loosening after being used for a period of time.

[0067] In this embodiment, the headrest massage assembly may include a headrest mounting seat 320, a headrest driving device, a first headrest massage plate 341, and a second headrest massage plate 342. The first side of the headrest mounting seat 320 is embedded in the headrest embedding groove 312, and the shape of the headrest embedding groove 312 can be adapted to the outer contour of the headrest mounting seat 320, so that the headrest mounting seat 320 will not shake after being embedded in the embedding groove 312.

[0068] A first mounting shaft 321 and a second mounting shaft 322 are provided on the second side of the headrest mounting seat 320, and a motor mounting groove 323 is provided on the second side of the headrest mounting seat 320. Limiting plates are provided at both ends of the motor mounting groove 323. After the headrest driving motor 330 is inserted into the motor mounting groove 323, the limiting plates have a limiting effect on the headrest driving motor 330 to prevent the headrest driving motor 330 from moving in the axial direction.

[0069] The headrest drive device includes a headrest drive motor 330, a first headrest worm gear 331 and a second headrest worm gear 332. The headrest drive motor 330 is arranged in the motor embedding groove 323, and both ends of the headrest drive motor 330 have output worms for outputting power, that is, the headrest drive motor 330 is a double-headed worm motor.

[0070] The first headrest worm gear 331 is arranged on the first installation shaft 321, and the second headrest worm gear 332 is arranged on the second installation shaft 322. The output worms at both ends of the headrest driving motor 330 are respectively matched with the first headrest worm gear 331 and the second headrest worm gear 332. The first headrest massage plate 341 is coaxially connected to the first headrest worm gear 331, and the second headrest massage plate 342 is coaxially connected to the second headrest worm gear 332. The headrest driving motor 330 transmits power to the first headrest worm gear 331 and the second headrest worm gear 332 through the output worm gears at both ends, so that the first headrest worm gear 331 and the second headrest worm gear 332 rotate accordingly. The first headrest worm gear 331 and the second headrest worm gear 332 then transmit power to the first headrest massage plate 341 and the second headrest massage plate 342. Through the rotation of the first headrest massage plate 341 and the second headrest massage plate 342, physical massage of the user's head and neck is achieved.

[0071] The power transmission mode between the first headrest worm gear 331 and the second headrest worm gear 332 and the first headrest massage plate 341 and the second headrest massage plate 342 respectively can be:

[0072] 1) The first mounting shaft 321 and the second mounting shaft 322 are rotatably arranged on the headrest mounting seat 320, and the first headrest massage plate 341 and the first headrest worm gear 331 are both fixed on the first mounting shaft 321, so that the first headrest worm gear 331 drives the first mounting shaft 321 and the first headrest massage plate 341 fixed on the first mounting shaft 321 to rotate. Similarly, the second headrest massage plate 342 and the second headrest worm gear 332 are both fixed on the second mounting shaft 322, so that the second headrest worm gear 332 drives the second mounting shaft 322 and the second headrest massage plate 342 fixed on the second mounting shaft 322 to rotate.

[0073] 2) The first mounting shaft 321 and the second mounting shaft 322 can be fixed on the headrest mounting seat 320, the first headrest worm gear 331 can be rotatably set on the first mounting shaft 321, the first headrest massage plate 341 is fixedly connected to the first headrest worm gear 331, and power can also be transmitted to the first headrest massage plate 341; similarly, the second headrest worm gear 332 can be rotatably set on the second mounting shaft 322, the second headrest massage plate 342 is fixedly connected to the second headrest worm gear 332, and power can also be transmitted to the second headrest massage plate 342.

[0074] like Figure 5 As shown, the first headrest massage plate 341 and the second headrest massage plate 342 are both provided with a first massage head 3411 and a second massage head 3412, and a plurality of transition massage heads 3413 provided between the first massage head 3411 and the second massage head 3412, and the volume of each transition massage head 3413 is smaller than the volume of the first massage head 3411 and the second massage head 3412.

[0075] Specifically, the volume of the second massage head 3412 is smaller than that of the first massage head 3411, and the volumes of the transition massage heads 3413 are different, and the volumes of the transition massage heads 3413 gradually decrease from the first massage head 3411 to the second massage head 3412. Figure 5 When the structure shown rotates clockwise, the first massage head 3411 with the largest size exerts the greatest massage force on the muscles, and then transitions to the transition massage head 3413 with the largest size, and then passes through each transition massage head 3413 in turn, and after passing through the transition massage head 3413 with the smallest size, the second massage head 3412 with a larger size massages the muscles with great force; then the transition massage head 3413 with the smallest size contacts the corresponding muscles to reset the muscles, and then passes through each transition massage head 3413 from small to large in turn, and finally passes through the first massage head 3411 with the largest size again.

[0076] In summary, when the transition massage head 3413 switches with the first massage head 3411 and the second massage head 3412, a more sudden massage effect will be produced. The larger transition massage head 3413 is arranged adjacent to the first massage head 3411, and the smaller transition massage head 3413 is arranged adjacent to the second massage head 3412. This can avoid massage pain caused by excessive massage force due to too large a sudden change.

[0077] like Figure 3 As shown, in a specific embodiment of the utility model, a waist and back embedding groove 101 for embedding a waist and back massage device 400 is provided on the back cushion 100. The waist and back massage device 400 includes a waist and back driving device 440, an eccentric wheel assembly and an open-back massage disc assembly. Among them, the waist and back driving device 440 is used to output power, the eccentric wheel assembly is connected to the waist and back driving device 440, and the open-back massage disc assembly is connected to the eccentric wheel assembly to drive the open-back massage disc assembly to swing. Under the action of the eccentric wheel assembly, the open-back massage disc assembly will be driven to swing, and then the user's waist and back will be physically massaged.

[0078] Furthermore, the waist and back driving device 440 includes a waist and back driving motor 441, a first waist and back worm gear 444, a second waist and back worm gear 445, a third waist and back worm gear 449 and a fourth waist and back worm gear 448. Among them, both ends of the waist and back driving motor 441 have output worms for outputting power, that is, the waist and back driving motor 441 is a double-headed worm motor.

[0079] The first back worm gear 444 and the second back worm gear 445 cooperate with the output worm gear at one end of the back driving motor 441. The third back worm gear 449 and the fourth back worm gear 448 cooperate with the output worm gear at the other end of the back driving motor 441. The back driving motor 441 can drive the first back worm gear 444, the second back worm gear 445, the third back worm gear 449 and the fourth back worm gear 448 to rotate.

[0080] The eccentric wheel assembly includes a first eccentric wheel 421, a second eccentric wheel 422, a third eccentric wheel 423 and a fourth eccentric wheel 424 which are respectively connected to the first waist-back worm wheel 444, the second waist-back worm wheel 445, the third waist-back worm wheel 449 and the fourth waist-back worm wheel 448 in a one-to-one transmission connection.

[0081] The open-back massage plate assembly includes a first open-back massage plate 450 and a second open-back massage plate 460.

[0082] The first open-back massage disc 450 can be driven to move by the rotation of the first eccentric wheel 421 and the third eccentric wheel 423, and the second open-back massage disc 460 can be driven to move by the rotation of the second eccentric wheel 422 and the fourth eccentric wheel 424. The first open-back massage disc 450 and the second open-back massage disc 460 are arranged in parallel and are used to be arranged on both sides of the user's lumbar spine. The first eccentric wheel 421 and the second eccentric wheel 422 rotate in opposite directions, and the third eccentric wheel 423 and the fourth eccentric wheel 424 rotate in opposite directions. When the first ends of the first open-back massage disc 450 and the second open-back massage disc 460 move toward each other, the second ends move away from each other; when the first ends of the first open-back massage disc 450 and the second open-back massage disc 460 move away from each other, the second ends move toward each other.

[0083] In a specific embodiment of the present invention, the cervical and lumbar massage pad may further include a first drive device fixing seat 410 and a second drive device fixing seat 430.
