Description

Technical Field

[0001] This utility model relates to the field of lumbar support technology, specifically to a pneumatic massage lumbar support. Background Technology

[0002] Lumbar supports are common components on chairs or sofas, designed for people who need back support. They can effectively relieve lower back fatigue and pain, and are especially suitable for people who sit for long periods of time, such as drivers and office workers.

[0003] Furthermore, to further enhance the fatigue-relieving effect of lumbar supports, many lumbar supports on the market have added massage functions. These lumbar supports include a main body and a massage board. The massage board, located on the front side of the main body, supports the user's waist. The main body and the massage board are connected by an air cushion. The air cushion can inflate and deflate in a regular manner, thereby pushing forward or pulling inward the massage board. This causes the massage board to push and press on the user's waist in a regular manner, more effectively relieving lumbar fatigue and providing greater comfort.

[0004] However, the above solution has the following problems: the air cushion is relatively soft, which makes it easy for the air cushion to deform when the massage board is pushed or pulled or when the massage board is leaned against by the waist. This causes the massage board to become tilted, making it unable to slide smoothly back and forth relative to the lumbar support body or fit the user's waist. In other words, the sliding adjustment operation of the massage board is not stable. Summary of the Invention

[0005] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a pneumatic massage lumbar support that constrains the sliding direction of the support plate through sliding cooperation of the sliding component and slot, so that the support plate is not easy to tilt under the action of external force, thereby maintaining the same posture and stably supporting the user's waist, with strong stability and effectively improving comfort.

[0006] The effect of this utility model is achieved as follows: This application provides a pneumatic massage lumbar support, including a lumbar support body, a support plate, and an airbag. The front end of the support plate is configured to mount a flexible pad. The support plate is located on the front side of the lumbar support body, and the support plate and the lumbar support body are connected by a sliding support structure. The sliding support structure includes a slider extending in a front-back direction and a slot. The slider is disposed in one of the support plate and the lumbar support body, and the slot is opened in the other of the support plate and the lumbar support body. The slider can slide back and forth along the slot, so that the support plate is slidably connected to the lumbar support body. There is a gap between the support plate and the lumbar support body, and the gap is configured as a receiving cavity. The airbag is located in the receiving cavity and is configured to inflate or deflate, thereby driving the lumbar support body to slide back and forth relative to the support plate. The slider slides back and forth along the slot.

[0007] Furthermore, the rear end of the support plate is connected to several sliding parts via screws, and the front side of the lumbar support body has several slots. The installation and operation between the sliding parts and the support plate are simple and the connection strength is high. Moreover, by setting multiple sets of sliding parts and slots, the connection strength between the support plate and the lumbar support body is high, which improves the stability of the pneumatic massage lumbar support.

[0008] Furthermore, the slider has an L-shaped curved irregular structure. This increases the connection strength between the slider and the lumbar support body, further improving the stability of the support plate's sliding adjustment operation.

[0009] Furthermore, an elastic element is provided between the support plate and the lumbar support body. The elastic force of the elastic element acts on the support plate, causing the support plate to always tend to move towards the lumbar support body. This not only allows the support plate to provide a more elastic support experience with the help of the elastic element, but also makes the support plate automatically return to its original position under the pull of the elastic element, thus making the repositioning operation of the support plate simpler.

[0010] Furthermore, the elastic element is a tension spring, and several mounting platforms are provided on the side wall of the support plate. The front end of the elastic element is pressed into the mounting platform by screws, and the rear end of the elastic element is pressed into the lumbar support body by screws. Not only is the elastic force sufficient, but the cost is also low, and the installation and disassembly of the elastic element are also relatively simple.

[0011] Furthermore, a positioning platform is formed on the front end of the lumbar support body, which is configured to install an airbag. Two positioning parts, upper and lower, are formed on the rear end of the support plate, and the positioning platform is clamped between the two positioning parts. This further enhances the connection strength and stability between the lumbar support body and the support plate, and also further improves the stability of the sliding adjustment operation of the support plate.

[0012] Furthermore, the front end of the positioning platform has a recessed positioning groove, in which the airbag is installed and fixed to the positioning platform by screws. This makes the installation and removal of the airbag relatively simple and ensures a high connection strength.

[0013] Furthermore, the pneumatic massage lumbar support also includes a mesh fabric and pressure plates. The mesh fabric covers the front end of the lumbar support body and conceals the support plate. The front end of the lumbar support body is connected to two pressure plates, one above the other, via screws. The pressure plates clamp the mesh fabric to the lumbar support body. This not only provides users with a more comfortable support experience but also makes the pneumatic massage lumbar support more aesthetically pleasing and allows for convenient installation and removal of the mesh fabric.

[0014] Furthermore, the lumbar support body is equipped with a remote control module, which is configured to exchange data with a mobile APP or WeChat mini-program to remotely control the pneumatic massage lumbar support to turn on or off, as well as the amplitude and frequency of the airbags. Not only is the adjustment operation simple, but users can also make more precise adjustments through the APP or mini-program.

[0015] Furthermore, the lumbar support body is equipped with an adjustment switch, which controls the pneumatic massage lumbar support to turn on or off. The pneumatic massage lumbar support has at least two adjustment modes, allowing users to freely choose the adjustment mode according to their own usage habits and environment, making operation more convenient.

[0016] The pneumatic massage lumbar support provided in this application utilizes the inflation and deflation of airbags to cause the support plate to slide back and forth relative to the support body, resulting in simple adjustment. The flexibility of the airbags allows the support plate to provide a more comfortable support experience for the user's lower back. Furthermore, the sliding depth of the support plate can be controlled by adjusting the air intake and exhaust volume, and the sliding speed can be controlled by adjusting the air intake and exhaust rates, thus controlling the massage intensity and frequency, offering a high degree of adjustment freedom. Moreover, the sliding mechanism and slots constrain the sliding direction of the support plate, preventing it from tilting under external forces and maintaining a stable posture to support the user's lower back, resulting in strong stability and effectively improving comfort.

Detailed Implementation

[0019] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0020] Please refer to the attached document. Figure 1-10 This application provides a pneumatic massage lumbar support, including a lumbar support body 1, a support plate 2, and an airbag 3. The front end of the support plate 2 is configured to install a flexible pad 4. The support plate 2 is located on the front side of the lumbar support body 1, and the support plate 2 and the lumbar support body 1 are connected by a sliding support structure. The sliding support structure includes a slider 5 extending in a front-back direction and a slot 110. The slider 5 is disposed in one of the support plate 2 and the lumbar support body 1, and the slot 110 is opened in the other of the support plate 2 and the lumbar support body 1. The slider 5 can slide back and forth along the slot 110, so that the support plate 2 is slidably connected to the lumbar support body 1. There is a gap between the support plate 2 and the lumbar support body 1, and the gap is configured as a receiving cavity 101. The airbag 3 is located in the receiving cavity 101. The airbag 3 is configured to inflate or deflate, and drives the lumbar support body 1 to slide back and forth relative to the support plate 2. The slider 5 slides back and forth along the slot 110.

[0021] In this embodiment, the airbag 3 inflates or deflates, causing the support plate 2 to slide back and forth relative to the lumbar support body 1 through changes in its thickness. This simple adjustment allows the flexible airbag 3 to provide a more comfortable support experience for the user's lower back. Furthermore, the sliding depth of the support plate 2 can be controlled by adjusting the air intake and exhaust volumes, and the sliding speed can be controlled by adjusting the air intake and exhaust rates, thus controlling the massage intensity and frequency, offering a high degree of adjustment freedom. Moreover, the sliding direction of the support plate 2 is constrained by the sliding member 5 and the slot 110, preventing it from tilting under external forces and maintaining a stable posture to support the user's lower back, resulting in strong stability and effectively improving comfort.

[0022] Preferably, the support plate 2 is an arc-shaped plate that bends backward in the middle, and the front end of the support plate 2 is provided with two symmetrical flexible pads 4, so that the shape of the support plate 2 fits the curve of the human waist more closely, and the two flexible pads 4 can face the two sides of the user's waist, which is ergonomic and further enhances the support experience.

[0023] Please refer to the appendix. Figure 7 The lumbar support body 1 is a split shell structure, including a front shell 1a and a rear shell 1b. A pneumatic assembly is provided between the front shell 1a and the rear shell 1b. The pneumatic assembly includes an air pump 9 and multiple air valves 10. The air pump 9, air valves 10, and airbag 3 are connected by air pipes. The air pump 9 is used to inflate the airbag 3, and the air valves 10 control the inflation amount and deflate the airbag 3. This makes the inflation and deflation of the airbag 3 simple and the control of the inflation and deflation amount more precise, thereby resulting in higher accuracy in adjusting the sliding depth of the support plate 2.

[0024] Please refer to the attached document. Figure 5-6 In some embodiments of this application, the rear end of the support plate 2 is connected to several sliding parts 5 by screws, and several slots 110 are provided on the front side of the waist support body 1.

[0025] In this embodiment, the sliding member 5 and the support plate 2 are fixed by screw connection, which is simple to install and has high connection strength. Furthermore, the support plate 2 and the lumbar support body 1 are connected by multiple sets of sliding members 5 and slots 110, which makes the connection strength between the support plate 2 and the lumbar support body 1 high and improves the stability of the pneumatic massage lumbar support.

[0026] Of course, in other embodiments of this application, the slider 5 can also be disposed on the lumbar support body 1, and a slot 110 can be opened on the support plate 2.

[0027] Please refer to the attached document. Figure 5-6In some embodiments of this application, the slider 5 has an L-shaped curved irregular structure. This makes the connection strength between the slider 5 and the lumbar support body 1 higher, further improving the stability of the sliding adjustment operation of the support plate 2.

[0028] Preferably, the support plate 2 has four sliding members 5 on its rear side, with the two upper sliding members 5 being straight columnar structures and the two lower sliding members 5 being curved L-shaped structures. When the support plate 2 is leaned against by a user, the lower sliding members 5 bear greater pressure. By making only the lower sliding members 5 into a higher-strength irregular shape, not only are manufacturing costs saved, but the connection strength between the support plate 2 and the lumbar support body 1 is also guaranteed.

[0029] Please refer to the attached document. Figure 3-5 In some embodiments of this application, an elastic element 6 is provided between the support plate 2 and the lumbar support body 1. The elastic force of the elastic element 6 acts on the support plate 2, so that the support plate 2 always has a tendency to move towards the lumbar support body 1.

[0030] In this embodiment, by setting an elastic element 6 between the support plate 2 and the lumbar support body 1, the support plate 2 can provide a more elastic support experience with the help of the elastic force of the elastic element 6. Moreover, when the airbag 3 deflates and contracts, the support plate 2 automatically resets backward under the pull of the elastic element 6, thereby making the reset operation of the support plate 2 more convenient.

Figure 4 In some embodiments of this application, the elastic element 6 is a tension spring, and a plurality of mounting platforms 210 are provided on the side wall of the support plate 2. The front end of the elastic element 6 is pressed onto the mounting platform 210 by screws, and the rear end of the elastic element 6 is pressed onto the lumbar support body 1 by screws.

[0032] In this embodiment, by using a tension spring, not only is the elastic force sufficient, but the cost is also low. The front and rear ends of the elastic element 6 are respectively pressed to the mounting platform 210 and the lumbar support body 1 by screws, making the installation and disassembly of the elastic element 6 relatively simple.

[0033] The lumbar support body 1 also has a tubular mounting part 140 on its front end face. The elastic element 6 is installed in the mounting part 140. When the elastic element 6 deforms, it will not detach from the mounting part 140, resulting in better connection stability.

[0034] Preferably, four sets of elastic elements 6 are provided between the support plate 2 and the lumbar support body 1, and four mounting platforms 210 are provided on the side wall of the support plate 2 to further enhance the elasticity between the support plate 2 and the lumbar support body 1.

[0035] Please refer to the attached document. Figure 5 and attached Figure 7In some embodiments of this application, a positioning platform 120 is formed on the front end of the lumbar support body 1. The positioning platform 120 is configured to install the airbag 3.
