[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-2 This utility model provides an embodiment of a multifunctional car lumbar support, including a lumbar support frame 1. A breathable mesh 2 is fixedly connected inside the lumbar support frame 1. The lumbar support frame 1, in conjunction with the breathable mesh 2, supports the user's back and prevents stuffiness. An elastic band 3 is fixedly connected to the back of the lumbar support frame 1. The elastic band 3 can be fitted onto the car seat to limit the installation of the lumbar support frame 1, preventing it from tilting forward and affecting its performance. A lumbar support bracket 4 is fixedly connected to the front of the lumbar support frame 1. The lumbar support bracket 4 has an overall arc-shaped structure and a support block 5 inside. Through the cooperation of the lumbar support bracket 4 and the support block 5, the user's lower back can be supported and protected. The overall arc-shaped structure of the lumbar support bracket 4 better conforms to the user's lower back, further enhancing the support effect.

[0032] Reference Figures 2-4There are several support blocks 5, and several lumbar supports 4 are arranged in a rectangular array. Adjacent support blocks 5 are fixedly connected by elastic ropes 6. The support blocks 5 on the periphery are also fixedly connected to the lumbar supports 4 by elastic ropes 6. Adjacent support blocks 5 can move relative to each other within the stretching range of the elastic ropes 6. The support blocks 5 and the lumbar supports 4 form a whole through the elastic ropes 6, which can support the user's waist. A fixing plate 7 is fixedly connected inside the lumbar support frame 1. A limiting cylinder 8 is detachably connected to the front surface of the fixing plate 7. An airbag 9 is fixedly connected to the rear inner wall surface of the limiting cylinder 8. The outer wall of the airbag 9 fits against the inner wall of the limiting cylinder 8. The airbag 9 is located directly behind the lumbar supports 4.

[0033] The limiting cylinder 8 can limit the expansion range of the airbag 9, so that the airbag 9 expands as far forward as possible. When the airbag 9 expands forward, it can support and limit the rear side of the support block 5, so that the support block 5 remains stable during use and provides sufficient support for the user's waist. At the same time, when the airbag 9 is continuously inflated and deflated, it can drive the support block 5 to continuously expand and contract back and forth, thereby massaging the user's waist and improving the functionality of the lumbar support.

[0034] An inflation unit is provided on the outside of the airbag 9. The inflation unit includes an air pump 91, which is fixedly connected to the center of the right side surface of the limiting cylinder 8. A control button (not directly shown in the figure) is provided on the outer surface of the air pump 91. The air pump 91 can also be controlled by mobile phone software, which is a prior art. A connecting pipe 92 is fixedly connected to the output end of the air pump 91. The end of the connecting pipe 92 away from the air pump 91 passes through the limiting cylinder 8, and the end of the connecting pipe 92 away from the air pump 91 is fixedly connected to the airbag 9. When the air pump 91 is started, it can inflate and deflate the airbag 9 through the connecting pipe 92, thereby driving the airbag 9 to inflate or continuously expand and contract. A battery compartment 93 is fixedly connected to the lower side of the right side surface of the limiting cylinder 8. The battery compartment 93 can hold dry batteries for easy replacement. The battery compartment 93 can be used as a power source for the air pump 91, which is convenient to use.

[0035] Reference Figures 4-5An L-shaped limiting bracket 10 is fixedly connected to the front surface of the fixing plate 7. The L-shaped limiting bracket 10 is sleeved on the outside of the limiting cylinder 8. A groove 11 is provided on the back of the fixing plate 7. A bolt 12 is provided inside the groove 11. The front end of the bolt 12 passes through the fixing plate 7 and the limiting cylinder 8. The bolt 12 is threadedly connected to both the fixing plate 7 and the limiting cylinder 8. The limiting cylinder 8 is detachably connected to the fixing plate 7 through the bolt 12. When the limiting cylinder 8 needs to be installed, it can be placed inside the L-shaped limiting bracket 10, so that the limiting cylinder 8 is completely fitted with the inner wall of the L-shaped limiting bracket 10. At this time, the bolt 12 will quickly align with the screw hole on the back of the limiting cylinder 8, thereby realizing the quick installation of the limiting cylinder 8 and facilitating the quick disassembly of the limiting cylinder 8, thus enabling the quick disassembly and maintenance of the inflation unit and the airbag 9.

[0036] Working principle: After placing the lumbar support frame 1 on the car seat, the elastic band 3 is put on the car seat to limit the lumbar support and prevent it from tilting. Then, the air pump 91 can be activated to inflate the airbag 9 through the connecting pipe 92, so that the airbag 9 can support and limit the rear side of the support block 5, and can expand the support block 5 to fit the user's waist, improving the support effect and avoiding the risk of collapse or deformation due to compression of the lumbar support area. During use, the air pump 91 can be controlled to continuously inflate and deflate the airbag 9, causing the airbag 9 to inflate or continuously expand and contract. At this time, the airbag 9 can move the support block 5 back and forth, massaging the user's waist and improving the functionality of the lumbar support.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
