Description

Technical Field

[0001] This utility model relates to the field of sofa support frame technology, and in particular to a sofa support frame with shock absorption function. Background Technology

[0002] The sofa support frame is an important component of the sofa structure. It not only needs to support the weight of the entire sofa, but also needs to be able to adapt to various sitting postures of the human body and provide good comfort. The structure and materials of the support frame have a direct impact on the choice of fabric and the fixing method, and also determine the overall stability and durability of the sofa.

[0003] In the prior art, a sofa base support frame, according to patent publication number CN222466493U, includes a base frame. The mounting cavity of the base frame contains, from top to bottom, a palm fiber pad layer, an elastic mesh layer, a woven strap layer, a tension spring layer, a supporting steel ring, and multiple sets of supporting strip plates. This utility model has a simple structure. By setting the palm fiber pad layer, it can effectively block and absorb moisture, effectively preventing the sofa base from being corroded by moisture and affecting the service life of the support frame, thus effectively improving moisture resistance. However, this device does not include shock absorption design for the sofa support frame. Therefore, without shock absorption design, the support frame will directly bear a large impact force during use, which will lead to fatigue and damage to the frame material, thereby shortening the sofa's service life and reducing its comfort. Utility Model Content

[0004] The purpose of this utility model is to provide a sofa support frame with shock absorption function, in order to solve the problem that the device does not have a shock absorption design for the sofa support frame. As a result, the sofa without a shock absorption design will directly bear a large impact force during use, which will lead to fatigue and damage to the frame material, thereby shortening the service life of the sofa and reducing the comfort of the sofa.

[0005] To achieve the above objectives, a sofa support frame with shock absorption function is provided, including a support base frame. Support side plates are fixed at both ends of the top of the support base frame. Shock-absorbing structures are provided around the inner perimeter of the top of the support base frame. Each shock-absorbing structure includes a shock-absorbing base plate. A shock-absorbing bottom frame is fixed at the center of the top of the shock-absorbing base plate. A shock-absorbing top column is embedded inside the top of the shock-absorbing bottom frame. A shock-absorbing buffer pad is fixed at the bottom of the inner side of the shock-absorbing bottom frame. The top of the shock-absorbing buffer pad is fixed to the bottom of the shock-absorbing top column. A shock-absorbing damper is fixed at the top of the shock-absorbing top column. The multiple shock-absorbing dampers and shock-absorbing base plates are arranged in a square shape.

[0006] According to the aforementioned sofa support frame with shock absorption function, the left and right ends of the inner side of the support base frame are fixed with snap-fit ​​frames, and shock-absorbing upper pads are snapped between the inner sides of multiple snap-fit ​​frames. The shock-absorbing upper pads are generally arranged in an I-shape.

[0007] According to the aforementioned sofa support frame with shock absorption function, threaded grooves are provided at both ends of the top surface of multiple shock-absorbing base plates, and multiple threaded grooves extend to the inner side of the support base frame.

[0008] According to the aforementioned sofa support frame with shock absorption function, the top surface of the shock-absorbing pad is provided with a shock-absorbing arc groove along the longitudinal direction, and the spacing between adjacent shock-absorbing arc grooves is consistent.

[0009] According to the aforementioned sofa support frame with shock absorption function, support blocks are fixed at both ends of the side of the shock-absorbing upper pad, and the outer sides of multiple support blocks are fixedly connected to the inner wall of the support bottom frame.

[0010] According to the aforementioned sofa support frame with shock absorption function, the inner wall of the shock-absorbing bottom frame and the outer side of the shock-absorbing upper column are both smoothly provided.

[0011] According to the aforementioned sofa support frame with shock absorption function, multiple inclined grooves are provided at both ends of the outer side of the support base frame.

[0012] According to the aforementioned sofa support frame with shock absorption function, the shock-absorbing upper pad is designed using polyurethane material.

[0013] The above solution has the following beneficial effects: It employs a shock-absorbing structure installed on all four sides of the inner side of the top of the supporting base frame. This involves embedding the shock-absorbing upper column inside the shock-absorbing base frame. Due to the addition of shock-absorbing buffer pads inside the base frame and shock-absorbing damping at the top of the upper column, the synergistic effect of multiple shock-absorbing buffer pads and damping provides an energy dissipation pathway, ensuring the supporting base frame maintains stable performance under various working conditions. This provides shock absorption and buffering within the supporting base frame. Furthermore, by adding multiple snap-fit ​​frames, the shock-absorbing upper pads are secured between these frames, maintaining their stability. The shock-absorbing upper pads also provide further shock absorption for the sofa body.

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figure 1-4This utility model discloses a sofa support frame with shock absorption function, comprising a support base frame 1, support side plates 2 fixed at both ends of the top of the support base frame 1, shock absorption structures arranged around the inner perimeter of the top of the support base frame 1, and multiple shock absorption structures including a shock absorption base plate 3. A shock absorption bottom frame 4 is fixed at the center of the top of the shock absorption base plate 3, a shock absorption top column 5 is embedded in the inner side of the top of the shock absorption bottom frame 4, and a shock absorption buffer pad 6 is fixed at the bottom of the inner side of the shock absorption bottom frame 4. The top of the shock absorption buffer pad 6 is fixed to the bottom of the shock absorption top column 5, and a shock absorption damper 7 is fixed at the top of the shock absorption top column 5. Multiple shock absorption dampers 7 and shock absorption base plates 3 are arranged in a square shape. In the prior art, this device does not have a shock absorption design for the sofa support frame, thus the sofa lacking a shock absorption design will experience shock absorption issues during use. During use, the support frame directly bears significant impact forces, which can lead to fatigue and damage to the frame material, thus shortening the sofa's lifespan and reducing its comfort. To address this issue, a shock-absorbing structure can be installed around the top inner side of the support base frame 1. This involves embedding the shock-absorbing upper column 5 inside the shock-absorbing base frame 4. With shock-absorbing buffer pads 6 added inside the shock-absorbing base frame 4 and shock-absorbing damping pads 7 added to the top of the shock-absorbing upper column 5, the synergistic effect of multiple shock-absorbing buffer pads 6 and shock-absorbing damping pads 7 provides an energy dissipation pathway, ensuring the support base frame 1 maintains stable performance under various operating conditions. This provides shock absorption and cushioning inside the support base frame 1, improving the overall performance of the sofa and enhancing its comfort.

[0024] Both ends of the inner side of the supporting base frame 1 are fixed with snap-fit ​​frames 8. The shock-absorbing upper pads 9 are snapped between the inner sides of multiple snap-fit ​​frames 8. The shock-absorbing upper pads 9 are I-shaped. By adding multiple snap-fit ​​frames 8, the shock-absorbing upper pads 9 are snapped between multiple snap-fit ​​frames 8, thereby maintaining the stability of the shock-absorbing upper pads 9. The shock-absorbing upper pads 9 can provide a further shock-absorbing effect to the sofa body. Both ends of the top surface of multiple shock-absorbing base plates 3 are provided with threaded grooves 10. Multiple threaded grooves 10 penetrate to the inner side of the supporting base frame 1, which facilitates the fixation of multiple shock-absorbing base plates 3.

[0025] The top surface of the shock-absorbing upper pad 9 has a longitudinally formed shock-absorbing arc groove 11. The spacing between adjacent shock-absorbing arc grooves 11 is consistent, which enhances the elastic deformation capacity of the shock-absorbing upper pad 9, enabling it to better absorb and disperse energy when subjected to vibration, thereby improving the shock absorption effect. Support blocks 12 are fixed at both ends of the side of the shock-absorbing upper pad 9. The outer sides of multiple support blocks 12 are fixedly connected to the inner wall of the support bottom frame 1, which further maintains the stability of both sides of the shock-absorbing upper pad 9.

[0026] The inner wall of the shock-absorbing bottom frame 4 and the outer side of the shock-absorbing upper column 5 are both smoothly designed to facilitate better integration of the shock-absorbing upper column 5 with the shock-absorbing bottom frame 4, thereby improving the buffering and support effect. Multiple inclined grooves 13 are opened at both ends of the outer side of the support bottom frame 1 to reduce the amount of raw materials used and save costs. The shock-absorbing upper pad 9 is designed with polyurethane material, which can provide good support while ensuring the shock absorption effect.

[0027] Working principle: First, multiple threaded grooves 10 are used to screw in reinforcing bolts, thereby fixing multiple shock-absorbing base plates 3 and maintaining the stability of the shock-absorbing structure. Then, when the sofa's supporting base frame 1 is subjected to a large impact force, causing a decrease in the sofa's performance, a shock-absorbing structure is installed on all four sides of the top inner side of the supporting base frame 1. This is achieved by embedding the shock-absorbing upper column 5 into the inside of the shock-absorbing base frame 4. Because a shock-absorbing buffer pad 6 is added inside the shock-absorbing base frame 4, and a shock-absorbing damping pad is added to the top of the shock-absorbing upper column 5... The synergistic effect of multiple shock-absorbing pads 6 and shock-absorbing damping 7 is achieved by providing an energy dissipation pathway, ensuring that the supporting base frame 1 maintains stable performance under various working conditions. This allows for shock absorption and cushioning inside the supporting base frame 1. Furthermore, by adding multiple snap-fit ​​frames 8, the shock-absorbing upper pad 9 is snapped between the multiple snap-fit ​​frames 8, thereby maintaining the stability of the shock-absorbing upper pad 9. The shock-absorbing upper pad 9 can also provide further shock absorption for the sofa body, thereby improving the use effect of the sofa body and enhancing comfort.

[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
