[0028] This embodiment provides a lumbar pillow with an easily detachable external power supply, such as... Figure 1 , Figure 2 and Figure 3 As shown, the lumbar pillow includes a pillow body 1 and a positioning component. The pillow body 1 has a battery compartment 110 and an assembly port 111 and a mounting port 112 connecting the battery compartment 110 to the outside. The assembly port 111 allows an external power supply to be inserted into the battery compartment 110. The positioning component is located on the pillow body 1 and at the mounting port 112. The positioning component is used to press and position the external power supply inserted into the battery compartment 110 within the battery compartment 110. This embodiment of the lumbar pillow, by forming a battery compartment 110, an assembly port 111, and a mounting port 112 on the pillow body 1, allows for convenient insertion and removal of an external power supply into the battery compartment 110 through the assembly port 111, without the need for any other specialized tools. The positioning component presses and positions the external power supply inserted into the battery compartment 110 within the battery compartment 110, maintaining the stability of the external power supply and meeting usage requirements.

[0029] like Figure 2 As shown, the lumbar pillow body 1 in this embodiment includes a frame 10 and a main body plate 11. The frame 10 is a hollow structure with openings. The main body plate 11 is detachably mounted on the frame 10 and located at the openings. The battery compartment 110 is formed on the main body plate 11. Specifically, in this embodiment, the main body plate 11 is fixed to the frame 10 by screws. The lumbar pillow provided in this embodiment can be applied to a chair, which includes a backrest, and the lumbar pillow is mounted on the backrest. Specifically, the lumbar pillow is mounted on the backrest via the frame 10. By designing the lumbar pillow body 1 as a separate frame 10 and main body plate 11, when it is necessary to repair the functional components of the lumbar pillow (such as the massage head), the main body plate 11 can be removed from the frame 10 without removing the entire lumbar pillow from the backrest. In addition, for seats with different functions, the structural design of the lumbar support may be different. In this case, only the main body plate 11 can be structurally modified, while the frame 10 does not need to be changed. In this way, the installation structure between the frame 10 and the backrest does not need to be changed, which can improve the versatility of the lumbar support.

[0030] Furthermore, the positioning component in this embodiment includes a connecting plate 2, a pressure plate 3, and an elastic member 4. The connecting plate 2 is disposed on the lumbar pillow body 1, and the pressure plate 3 is rotatably disposed on either the connecting plate 2 or the lumbar pillow body 1. The pressure plate 3 has a pressure-applying portion 320 extending into the battery compartment 110. The elastic member 4 is disposed between the pressure plate 3 and the connecting plate 2, and applies pressure to the pressure plate 3 such that the pressure-applying portion 320 tends to swing into the battery compartment 110. Through this structural design, the external power supply placed in the battery compartment 110 can be pressed and positioned within the battery compartment 110 using the pressure-applying portion 320. It is easily understood that an operator can insert the external power supply into the battery compartment 110 through the assembly port 111. When the end of the external power supply contacts the pressure-applying portion 320, the operator can push the pressure-applying portion 320 to overcome the elastic force of the elastic member 4, causing the pressure plate 3 to swing, thereby allowing the external power supply to be placed into the battery compartment 110. Subsequently, under the pressure of the elastic element 4, the pressure plate 3 applies force to the external power supply through the pressure part 320. The two sides of the external power supply are pressed against the inner wall of the battery compartment 110 by the pressure part 320, thereby providing a stable force for the external power supply. When it is necessary to remove the external power supply, the operator can directly pull the external power supply out of the battery compartment 110.

[0031] like Figure 3 As shown, in this embodiment, the pressure plate 3 is provided with a rotating shaft 300 and is rotatably mounted on the connecting plate 2 via the rotating shaft 300. Specifically, in this embodiment, the connecting plate 2 has a through hole 20, a transition groove 21 is formed on the side of the connecting plate 2 away from the battery compartment 110, and a limiting part 22 is formed on the side facing the battery compartment 110. The rotating shaft 300 is rotatably mounted on the transition groove 21. The pressure plate 3 is disposed through the through hole 20 so that the pressure application part 320 extends into the battery compartment 110, and the elastic member 4 is disposed between the limiting part 22 and the pressure plate 3. The above structural design facilitates the assembly operation between the various components.

[0032] Furthermore, in combination Figure 4 As shown, the positioning component in this embodiment also includes a cover plate 5 detachably mounted on the connecting plate 2. The cover plate 5 has a covering portion 50 adapted to the transition groove 21, which is used to prevent the rotating shaft 300 from disengaging from the transition groove 21. Specifically, the cover plate 5 is fixed to the connecting plate 2 by screws. In addition, to facilitate the assembly of the cover plate 5 and the connecting plate 2, this embodiment also provides a positioning protrusion 51 on the cover plate 5 and a positioning hole 23 adapted to the positioning protrusion 51 on the connecting plate 2. During assembly, the positioning protrusion 51 on the cover plate 5 is aligned with the positioning hole 23 on the connecting plate 2 and inserted to facilitate the assembly alignment operation. It is easy to understand that in other optional embodiments, the positioning hole 23 can also be provided on the cover plate 5, and correspondingly, the positioning protrusion 51 can be provided on the connecting plate 2.

[0033] In this embodiment, the elastic element 4 is a compression spring. The pressure plate 3 has a first positioning groove 321 and a first positioning post 322 located within the first positioning groove 321. The limiting part 22 has a second positioning groove 220 and a second positioning post 221 located within the second positioning groove 220. During assembly, one end of the elastic element 4 is sleeved on the outside of the first positioning post 322 and abuts against the bottom wall of the first positioning groove 321, and the other end of the elastic element 4 is sleeved on the outside of the second positioning post 221 and abuts against the bottom wall of the second positioning groove 220. Of course, in other optional embodiments, an elastic body such as a metal spring sheet can also be used as the elastic element 4. Further, such as Figure 3 and Figure 4 As shown, in this embodiment, the end face of the first positioning post 322 does not extend out of the first positioning groove 321, and similarly, the end face of the second positioning post 221 does not extend out of the second positioning groove 220. This does not increase the wall thickness of the pressure plate 3 and the limiting part 22.

[0034] The pressure plate 3 in this embodiment includes a first plate segment 30, an arc-shaped transition segment 31, and a second plate segment 32, all formed as a single unit. A rotating shaft 300 is formed at one end of the first plate segment 30, and a pressure-applying part 320 is formed in the second plate segment 32. Designing the pressure plate 3 as a single unit improves its overall strength and rigidity, reduces gaps between components, and prevents loosening and damage due to long-term use. The arc-shaped transition segment 31 ensures a smooth transition between the first plate segment 30 and the second plate segment 32, reducing stress concentration and improving the fatigue resistance of the pressure plate 3. It is readily understood that the aforementioned first positioning groove 321 and first positioning post 322 are formed on the side of the second plate segment 32 facing the limiting part 22.

[0035] As mentioned above, the lumbar pillow provided in this embodiment can be applied to a chair, which includes a backrest, and the lumbar pillow is disposed on the backrest.

[0036] Finally, it should be noted that the above embodiments are only optional embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
