Description

Technical Field

[0001] This application belongs to the field of seat manufacturing technology, specifically relating to a novel seat base and seat. Background Technology

[0002] In existing technologies, the seat base, as the core supporting component of a seating system, directly determines the stability, safety, and comfort of the seat through its structural design. It is widely used in various scenarios such as automobiles, office furniture, and public facilities, providing support for occupants, distributing body pressure, alleviating fatigue from long periods of sitting, and improving the user experience. However, current seat bases on the market still have many shortcomings in terms of structural design, material selection, and functional compatibility, making it difficult to meet the modern user's demand for high-performance, high-comfort seats.

[0003] In existing technologies, traditional seat bases often employ exposed cushioning spring structures. While these provide basic shock absorption, the springs are directly exposed to the outside of the base, severely compromising the overall aesthetics. Furthermore, they are susceptible to dust, foreign object corrosion, and external impacts during use, leading to a decrease in cushioning performance and a significantly shortened lifespan. Seat bases filled with a single foam material can achieve cushioning through material deformation, but the foam is fixed within the base shell, limiting deformation space and severely restricting shock absorption. Additionally, gaps can easily appear between the base and backrest when adjusting the seat angle, reducing support. Seat bases with frames made of ordinary plastic or low-cost engineering plastics, while having lower production costs, lack structural strength and are prone to deformation or even breakage under dynamic loads, failing to guarantee safety in collision scenarios. They also have poor durability, easily exhibiting fatigue damage and aging after prolonged use.

[0004] Therefore, in order to comprehensively improve the structural strength, cushioning performance, and aesthetics of the seat base, and to solve the defects of existing technologies such as easy damage to the cushioning structure, poor comfort, and insufficient safety, it is urgent to develop a new type of seat base to optimize support stability and riding experience, extend service life, and meet the usage needs of various scenarios. Utility Model Content

[0005] In order to solve the technical problems of exposed cushioning springs in existing seat bases being easily damaged and having poor aesthetics, limited shock absorption due to single foam material, and insufficient strength, safety, and durability of ordinary plastic frames, this application proposes a new type of seat base.

[0006] This application adopts the following solution: a novel seat base, including a base body, a cover disposed on the base body, a buffer spring disposed between the cover and the base body, and a connecting mechanism disposed between the cover and the buffer spring. The cover is detachably disposed on the base body through the connecting mechanism. The base body and the cover together form an installation position, and the buffer spring is matched and disposed within the installation position.

[0007] In some feasible embodiments, the connecting mechanism includes a connecting groove on the base body and connecting ears on both sides of the cover at corresponding positions of the connecting groove, the connecting ears being able to fit into the connecting groove.

[0008] In some feasible embodiments, the connecting mechanism further includes a fixing component disposed between the cover and the base body, the fixing component being used to fix the cover to the base body.

[0009] In some feasible embodiments, the fixing component includes a group of fixing holes disposed between the sidewall of the connecting groove and the connecting lug, and a fixing pin matched within the group of fixing holes.

[0010] In some feasible embodiments, a positioning component is also included between the cover and the base body, the positioning component being used to position the buffer spring within the installation position.

[0011] In some feasible embodiments, the positioning component includes a first positioning protrusion disposed on the inner side of the cover and a second positioning protrusion disposed on the base body, with one end of the buffer spring fitted onto the first positioning protrusion and the other end fitted onto the second positioning protrusion.

[0012] In some feasible embodiments, a limiting portion is also provided on the cover, the limiting portion being used to restrict the movement of the buffer spring away from the installation position.

[0013] In some feasible embodiments, the cover is made of metal.

[0014] In order to solve the technical problems raised in this application, this application also provides a seat, including a novel seat base as described above.

[0015] Compared with the prior art, this application has the following beneficial effects:

[0016] This application provides a novel seat base and seat, comprising a base body, a cover disposed on the base body, a buffer spring disposed between the cover and the base body, and a connecting mechanism disposed between the cover and the buffer spring. The cover is detachably mounted on the base body via the connecting mechanism. The base body and the cover together form an installation position, within which the buffer spring is fitted. The enclosed installation position formed by the base body and the cover accommodates the buffer spring, preventing it from being exposed to dust and external impacts.

[0023] Combination Figures 1 to 6 The following description further illustrates the technical solution proposed in this application. This application provides a novel seat base, including a base body 1, a cover 2 disposed on the base body 1, a buffer spring 3 disposed between the cover 2 and the base body 1, and a connecting mechanism 4 disposed between the cover 2 and the buffer spring 3. The cover 2 is detachably disposed on the base body 1 via the connecting mechanism 4. The base body 1 and the cover 2 together form an installation position 5, and the buffer spring 3 is matched and disposed within the installation position 5.

[0024] This application provides a novel seat base, comprising a base body, a cover disposed on the base body, a buffer spring disposed between the cover and the base body, and a connecting mechanism disposed between the cover and the buffer spring. The cover is detachably mounted on the base body via the connecting mechanism. The base body and the cover together form an installation position, within which the buffer spring is fitted. The enclosed installation position formed by the base body and the cover accommodates the buffer spring, preventing it from being exposed to dust and external impacts. This not only improves the aesthetics of the seat but also effectively protects the buffer spring and extends its service life. The detachable cover facilitates user maintenance and replacement of components, reducing operating costs. It has the advantages of reasonable structure, strong adaptability, simple operation, improved user experience, low implementation cost, and ease of promotion and implementation.

[0025] In actual assembly, the buffer spring is first pre-fixed to the inside of the cover. Then, the cover is detachably connected to the base body via a connecting mechanism, allowing the base body and cover to precisely enclose a semi-enclosed installation position. The buffer spring is then fitted into the position, ensuring the positioning of all components. When a passenger sits on the cover, the body pressure is transmitted to the buffer spring below. The buffer spring undergoes elastic deformation under axial pressure, absorbing impact energy and achieving a shock absorption effect. After the pressure disappears, the buffer spring returns to its original shape due to its elasticity, causing the cover to reset and maintaining support stability. When the buffer spring ages, becomes damaged, or needs replacement, the connecting mechanism is disassembled, separating the cover from the base body. The buffer spring can then be removed from the installation position for maintenance or replacement. After the operation is completed, the cover is reassembled for reuse.

[0026] In actual implementation, the semi-enclosed installation station can isolate the buffer spring from the external environment, preventing dust, foreign object corrosion and external force collisions, solving the problem of easy damage of existing exposed springs and extending the service life of the springs; at the same time, the cover covers the internal structure, improves the overall aesthetics of the seat base, and avoids the visual defects of exposed springs.

[0027] In this embodiment, the connecting mechanism 4 includes a connecting groove 40 on the base body 1 and connecting ears 41 on both sides of the cover 2 at corresponding positions of the connecting groove 40. The connecting ears 41 can be matched and extended into the connecting groove 40.

[0028] In this embodiment, the connecting mechanism 4 further includes a fixing component 42 disposed between the cover 2 and the base body 1, the fixing component 42 being used to fix the cover 2 to the base body 1.

[0029] In this embodiment, the fixing component 42 includes a fixing hole group 43 disposed between the side wall of the connecting groove 40 and the connecting ear 41, and a fixing pin 44 matched and disposed within the fixing hole group 43.

[0030] In actual implementation, the connecting ears on both sides of the cover are aligned with the connecting grooves on the base body. The user smoothly inserts the connecting ears into the groove along the opening direction of the groove. At this time, the cover and the base body are initially positioned, and the semi-closed contour of the installation position is formed. Then, the fixing pin is inserted axially along the fixing hole group until both ends of the fixing pin are in contact with the outer wall of the connecting groove and the inner wall of the connecting ear, respectively. Through the radial limiting effect of the fixing pin, the connecting ear is prevented from moving axially or radially along the connecting groove, and finally the cover and the base body are fixedly assembled, and the buffer spring is stably limited in the installation position. In the implementation of this embodiment, a positioning component 6 is also provided between the cover 2 and the base body 1. The positioning component 6 is used to position the buffer spring 3 in the installation position 5.

[0031] In this embodiment, the positioning component 6 includes a first positioning protrusion 60 located inside the cover 2 and a second positioning protrusion 61 located on the base body 1. One end of the buffer spring 3 is fitted onto the first positioning protrusion 60, and the other end is fitted onto the second positioning protrusion 61.

[0032] In actual implementation, when installing the buffer spring, first align the inner ring of one end of the buffer spring with the first positioning protrusion on the inner side of the cover, and slide it in axially along the protrusion until the end of the spring is in contact with the inner wall of the cover (the diameter of the first positioning protrusion is smaller than the diameter of the inner ring of the spring); then align the inner ring of the other end of the spring with the second positioning protrusion on the base body, and slide it in axially as well until the other end of the spring is in contact with the surface of the base body. At this time, the first and second positioning protrusions pass through the inner rings at both ends of the spring respectively; through their radial contact with the inner ring of the buffer spring, the displacement of the buffer spring in the horizontal direction (perpendicular to the axial direction of the protrusion) is restricted, thus completing the precise positioning of the buffer spring in the installation position.

[0033] In actual implementation, when the seat is under pressure, the cover presses down on the buffer spring, causing the spring to undergo axial compression deformation. At this time, the first positioning protrusion moves downwards synchronously with the cover, always passing through the upper inner ring of the spring, while the second positioning protrusion is fixedly passed through the lower inner ring of the spring. Through their continuous contact with the inner ring of the spring, both prevent the buffer spring from radially shifting (such as lateral swaying or tilting) or axially misaligning (such as relative sliding between the upper and lower ends) due to uneven force distribution. This ensures that the spring's deformation path always proceeds axially, and the buffering force is evenly transmitted to the base body, avoiding localized stress concentration that could lead to premature spring damage.

[0034] In this embodiment, a limiting part 7 is also provided on the cover 2, which is used to restrict the buffer spring 3 from moving away from the installation position 5.

[0035] In this embodiment, the protective cover 2 is made of metal.

[0036] In actual implementation, the metal cover, due to its rigidity, allows the connecting ears on both sides of the cover to be precisely aligned with the connecting grooves on the base body when assembled with the base body. It is then fixed by the fixing components, achieving precise positioning without additional calibration. At the same time, the structural strength of the metal cover can prevent deformation caused by external pressure during assembly, ensuring the structural stability of the installation position.

[0037] In order to solve the technical problems raised in this application, this application also provides a seat, which includes the novel seat base described above.

[0038] This application provides a novel seat base, comprising a base body, a cover disposed on the base body, a buffer spring disposed between the cover and the base body, and a connecting mechanism disposed between the cover and the buffer spring. The cover is detachably mounted on the base body via the connecting mechanism. The base body and the cover together form an installation position, within which the buffer spring is fitted. The enclosed installation position formed by the base body and the cover accommodates the buffer spring, preventing it from being exposed to dust and external impacts. This not only improves the aesthetics of the seat but also effectively protects the buffer spring and extends its service life. The detachable cover facilitates user maintenance and replacement of components, reducing operating costs. It has the advantages of reasonable structure, strong adaptability, simple operation, improved user experience, low implementation cost, and ease of promotion and implementation.
