Description

Technical Field

[0001] This utility model relates to the field of battery pack technology, and in particular to a novel lumbar support chair. Background Technology

[0002] With the rapid development of society and increasing pressure, heavy workloads and studies have led to a greater reliance on chairs. Prolonged periods of poor posture while working or studying can, over time, cause changes in physical posture, and even lead to lumbar muscle strain and spinal disorders, causing inconvenience and distress to one's health and daily life.

[0003] With current technology, it's difficult for chairs on the market to effectively support and correct the lower back, hips, and legs. Each user's height and body shape are different, and the lack of backrest adjustment in current products means the backrest cannot properly conform to the lumbar region of different users.

[0004] Most existing chairs use traditional foam or dual-density mesh fabric, but they have poor support and breathability. Utility Model Content

[0005] Purpose of the invention: The purpose of this utility model is to provide a new type of lumbar support chair to solve the problems of poor support and poor breathability in existing sitting chairs.

[0006] Technical solution:

[0007] A novel lumbar support chair includes a main body, which is divided into a seat cushion and a backrest. An air cushion is provided on the main body. The air cushion includes a base, on which several deformable columns are arranged in an array. Air channels are left between adjacent deformable columns. An air cavity is provided inside the deformable column, and an air hole is provided on the deformable column to connect the air cavity.

[0008] Preferably, the main body is provided with a connecting hole that extends through the deformable column along the axial direction, and the deformable column is provided with a bottom hole that communicates with the connecting hole and the bottom hole communicates with the air cavity.

[0009] Preferably, the deformable column has at least one air return hole, which is connected to the air chamber.

[0010] The return air hole improves the return air effect of the deformable column and prevents the deformable column from failing to reset. The position of the return air hole can be adjusted arbitrarily to facilitate air circulation between the air chamber and the outside.

[0011] Preferably, the return air hole is located on the side of the deformable column away from the air passage.

[0012] Preferably, air cushions are connected to both the seat cushion and the backrest, and air guide grooves that separate the air cushions are provided in the center of both the seat cushion and the backrest.

[0013] Preferably, the seat cushion has expansion slots at both ends of the air guide groove.

[0014] The air channels are designed to create gaps, preventing users from sitting too close to the chair and becoming unable to separate. They also form additional expansion channels to improve comfort.

[0015] Preferably, the deformable column comprises silicone material.

[0016] Preferably, the backrest has a handhold.

[0017] Preferably, the main body has mounting grooves on both the seat cushion and the backrest, and the air cushion is fixedly connected to the inner wall of the mounting groove.

[0018] Preferably, the deformable body includes a polygonal prism structure.

[0019] The structure of the deformable body can be selected in different forms as needed, mainly in the form of columnar structures, including cylinders and polygonal prisms, which can provide good support and reduce collapse.

[0020] Beneficial effects: The deformable column array air chamber structure can deform in real time according to the user's weight and sitting posture, and rebounds quickly, avoiding "collapse" or "back strain"; air channels are formed between adjacent deformable columns, and the return air holes on the top / side walls of the columns create circulating airflow, preventing stuffiness and sweating even after prolonged sitting; the return air holes are preferentially located at the bottom of the columns, away from the air channels, and the bottom holes open and close preferentially when standing up, instantly releasing pressure and eliminating the discomfort of "sucking"; the air guide groove divides the air cushion in two, and the left and right air chambers do not interfere with each other, so that pressure on one side will not cause the other side to collapse, and the support is always balanced; the outer lip of the silicone air cushion is interference-fitted with the mounting groove, allowing for tool-free insertion; when needed, it can be permanently fixed by applying glue, making assembly simple and maintenance convenient; the connecting hole is coaxial with the bottom hole of the deformable column to form a through air path, and the entire cushion is inflated / deflated at the corners; the handle on the backrest makes it easy to move and adjust the position, improving the user experience.

[0027] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Example 1

[0029] like Figure 1 As shown, a new type of lumbar support chair includes a main body 11, which is an integrally molded L-shaped frame structure. The structure of the main body 11 conforms to the curve of the human body and can provide a good support effect. The main body 11 is divided into a seat cushion 12 and a backrest 13, which conform to the user's buttocks and waist respectively.

[0030] The main body 11 is provided with an air cushion 14, which is integrally thermoformed. The outer edge of the air cushion 14 can be formed with a lip to facilitate embedding and installation.

[0031] Air Cushion 14 primarily uses flexible materials that are prone to deformation, including gel and rubber materials.

[0032] like Figure 2 and 3 As shown, the main body 11 has mounting grooves 15 on both the seat cushion 12 and the backrest 13. The air cushion 14 is embedded in the mounting groove 15. The friction is increased by the deformation of the lip, which facilitates the movement of the air cushion 14. At the same time, the air cushion 14 can be glued and fixed in the mounting groove 15.

[0033] like Figure 4 As shown, the air cushion 14 includes a chassis 16, which is directly connected to the inner wall of the mounting groove 15. Several deformable columns 17 are arranged in an array on the chassis 16. The height of the deformable columns 17 is much greater than the thickness of the chassis 16, so that the deformable columns 17 can extend to support the user.

[0034] The deformable column 17 and the chassis 16 are integrally formed structures. The shape of the column can be adjusted as needed, including cylindrical and polygonal prism structures, which can provide good support. There are ventilation channels 18 between each pair of adjacent deformable columns 17 to ensure that you do not sweat after sitting for a long time.

[0035] like Figure 5As shown, each deformable column 17 is further provided with an air chamber 19, and the deformable column 17 is also provided with a return air hole 20 communicating with the air chamber 19. There is at least one return air hole 20. The return air hole 20 can be provided on the top wall or side wall of the deformable column 17 as needed. The air filling and deflating effect is achieved through the return air hole 20, which can achieve a good support effect. In another embodiment, the number of return air holes 20 can be increased as needed.

[0036] Meanwhile, the return air vent 20 is preferably located on the side of the deformable column 17 away from the ventilation channel 18. The return air vent 20 can be close to the bottom of the deformable column 17. When the user stands up, the return air vent 20 at the bottom opens first to quickly release pressure and avoid "sucking" the buttocks or waist.

[0037] The main body 11 is also provided with several connecting holes 21 that pass through the deformable column 17 along the axial direction. The connecting holes 21 correspond one-to-one with the deformable column 17. The bottom of the deformable column 17 is provided with a bottom hole, which is located on the same axis as the connecting holes 21, so as to facilitate the formation of air passage communication and improve the air return effect of the deformable column 17.

[0038] The center of the air cushion 14 is divided into two by an air guide groove 22, forming two independent air chambers on the left and right sides to prevent unilateral collapse from causing unbalanced support. The air guide groove 22 is set on the main body 11, and the seat cushion 12 and backrest 13 are also provided with corresponding air guide grooves 22. The air guide groove 22 is located in the center position.

[0039] In another embodiment, the air guide groove 22 is located at the center of the air cushion 14, and the two air cushions 14 are connected to one end of the air guide groove 22 to facilitate the installation of the air cushion.

[0040] Furthermore, the seat cushion 12 is provided with expansion slots 24 at both ends of the air channel 22. The expansion slots 24 are at the same height as the chassis 16, which facilitates the improvement of ventilation and heat dissipation effect according to the user's body structure.

[0041] The backrest 12 has a handle opening 23 milled out at the lower edge of the corresponding scapula, and the edge is covered with soft TPU, which makes it easy to move the chair and can also serve as a temporary hook in a narrow office space.

[0042] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
