DETAILED DESCRIPTION
[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0027] Please refer to Figures 1-6 The utility model provides a technical scheme: an impact-resistant automobile seat waist support, comprising:
[0028] Two mounting frames 1 and driving members 2 arranged on one side of the two mounting frames 1;
[0029] The lumbar support mechanism 3 is installed on one side of the drive unit 2 to protect the driver's waist. It includes an outer fabric 31 fixedly connected to one side of the drive unit 2. Memory foam 32 is installed on the top of the inner cavity of the outer fabric 31. Mounting plates 33 are provided on both sides of the inner cavity of the outer fabric 31, and a cushioning component 34 for cushioning the driver's waist is provided between the two mounting plates 33.
[0030] Reference Figure 4 as well as Figure 5 As shown, the buffer assembly 34 includes a metal support mesh 341 disposed at the bottom of the memory foam 32. Support plates 342 are fixedly installed on both sides of the metal support mesh 341. Memory foam 343 is filled at the bottom of the metal support mesh 341 and inside the mounting frame 1. Several piston cylinders 344 are installed on the adjacent side of the two mounting plates 33. A piston plate 345 is slidably installed inside the piston cylinder 344. A piston rod 346 is fixedly installed on one side of the piston plate 345. One end of the piston rod 346 passes through the piston cylinder 344 and is fixedly connected to the side of the support plate 342. A return spring 347 is fixedly installed on the other side of the piston plate 345. One end of the return spring 347 is fixedly connected to the inner wall of the piston cylinder 344.
[0031] In this embodiment, when the driver is subjected to impact or vibration, the impact force will cause the driver to move backward on the seat, which will compress the lumbar support mechanism 3. The memory foam 32 and memory foam 343 inside the lumbar support mechanism 3 will gradually soften under pressure, dispersing the impact force to a larger area to reduce the pressure on the waist caused by the impact.
[0032] Reference Figure 4 as well as Figure 5 As shown, a buffer airbag 348 is provided on the side of the memory foam 343 away from the metal support mesh 341. Both ends of the buffer airbag 348 are connected to hoses 349. The end of the hose 349 away from the buffer airbag 348 passes through the mounting plate 33 and is connected to one side of the piston cylinder 344.
[0033] In this embodiment, when the impact force is too great, the memory foam 32 and memory foam 343 will be further compressed, and the cushioning airbag 348 on one side of the memory foam 343 will be squeezed. When the cushioning airbag 348 is subjected to force, the gas inside it is injected into the piston cylinder 344 through the connection between the hose 349 and the piston cylinder 344 to increase the pressure and push the piston plate 345. Then, the piston rod 346 is connected to the support plate 342 to squeeze the metal support mesh 341, causing the metal support mesh 341 to arch up, thereby changing the support shape of the metal support mesh 341 and protecting the driver's waist according to different impact forces.
[0034] Reference Figure 1 as well asFigure 6 As shown, the drive unit 2 includes a support housing 21 slidably disposed on the surfaces of two mounting brackets 1. A rack 22 is fixedly installed inside each of the two mounting brackets 1. A dual-axis motor 23 is installed inside the support housing 21. A drive rod 24 is fixedly installed at the output end of the dual-axis motor 23. Two limiting grooves 25 are opened on one side of the support housing 21. The limiting grooves 25 are fitted onto the surface of the mounting bracket 1 and slidably connected to it. The end of the drive rod 24 away from the dual-axis motor 23 passes through the support housing 21 and extends into the interior of the limiting groove 25. A gear 26 is fixedly installed at the end of the drive rod 24 located inside the limiting groove 25. One side of the gear 26 passes through the mounting bracket 1 and meshes with the rack 22.
[0035] In this embodiment, the dual-axis motor 23 can drive the drive rod 24 and the gear 26 to rotate, and the meshing connection between the gear 26 and the rack 22 can drive the drive member 2 and the lumbar support mechanism 3 to slide on the surface of the mounting frame 1, so as to adjust the lumbar support mechanism 3 to a suitable position according to the sitting posture of different drivers; and a sliding block can be added between the limiting groove 25 and the mounting frame 1 to prevent the mounting frame 1 and the drive member 2 from separating.
[0036] Reference Figure 1 As shown, both ends of the two mounting brackets 1 are fixedly mounted with fixing plates 4, and bolts 5 are installed through the surface of the fixing plates 4. The fixing plates 4 are fixedly connected to the car seat by the bolts 5.
[0037] In this embodiment, the mounting bracket 1 can be fixed to the rear of the car seat by the fixing plate 4 and bolts 5, which facilitates the installation and disassembly of the device, so that the user can replace the device.
[0038] Reference Figure 3 as well as Figure 4 As shown, the support plate 342 is arc-shaped, the mounting plate 33 is elliptical, and both the mounting plate 33 and the support plate 342 are made of hard plastic.
[0039] In this embodiment, the outer fabric 31 is wider than the waist of most drivers, which allows the buffer assembly 34 to be installed without affecting the driver's riding experience, thanks to the non-deformable properties of rigid plastic, thus preventing deformation of the mounting plate 33 and the support plate 342.
[0040] Reference Figure 1 as well as Figure 2 As shown, the outer fabric 31 is made of cotton, and the interior of the outer fabric 31 and the gaps between it and the memory foam 32 and the cushioning airbag 348 are filled with sponge.
[0041] In this embodiment, the driver's waist area can be kept breathable, thus avoiding affecting the driver's riding comfort.
[0042] Working principle: When the driver is subjected to impact or vibration, the impact force will cause the driver to move backward on the seat, compressing the lumbar support mechanism 3. The memory foam 32 and memory foam 343 inside the lumbar support mechanism 3 will gradually soften under pressure, dispersing the impact force over a larger area to reduce the pressure on the waist. When the impact force is too large, the memory foam 32 and memory foam 343 will be further compressed, compressing the buffer airbag 348 on one side of the memory foam 343. When the buffer airbag 348 is subjected to force, the gas inside it is injected into the piston cylinder 344 through the connection between the hose 349 and the piston cylinder 344 to increase the pressure and push the piston plate 345. Then, the piston rod 346 is connected to the support plate 342 to compress the metal support mesh 341, causing the metal support mesh 341 to arch and change its support shape. This can protect the driver's waist according to different impact forces.
[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
