AI Technical Summary
When the existing car seat frame spring frame is subjected to downward pressure from the user, a large tension occurs between the hook part and the shaft body, which can easily lead to deformation of the hook, thereby affecting the support effect of the spring frame.
A new type of car seat frame spring frame is designed, including two cross rods, several stretch spring bodies and hooks fixed at both ends of the stretch spring body. The hooks are movably connected to the surface of the cross rod, and the limit fixation of the hook is achieved through structures such as fixing blocks, shells, movable cavitys, movable plates, springs, connecting rods, positioning rods and control rods.
By limiting the hook, the service life of the hook is extended, the deformation of the hook is avoided when under pressure is maintained, and the support effect of the spring frame is improved.

Technical Field
[0001] The utility model belongs to the technical field of spring frames, and relates to a seat frame spring frame, in particular to a new type of automobile seat frame spring frame. Background Art
[0002] An automobile seat frame spring frame generally refers to the spring skeleton structure inside the seat. It is mainly composed of springs and other connecting parts, and is used to support the seat cushion and backrest of the seat to ensure the comfort and safety of passengers during the ride.
[0003] The existing spring frame structures on the market mainly include multiple tension spring bodies. The end of the tension spring body is bent to form a hook part, and this hook part is hooked on the rod body at a specified position. The entire spring frame structure is horizontally laid on the seat skeleton. During actual use, the spring frame will be subjected to the downward pressure of the user, and a large tensile force will be generated between the hook part on the spring frame and the shaft body, which is likely to cause the hook to deform, and then lead to a poor support effect of the spring frame. Therefore, it is of great significance to design a new type of automobile seat frame spring frame. Summary of the Invention
[0004] The purpose of the utility model is to provide a new type of automobile seat frame spring frame for the above problems existing in the prior art.
[0005] The purpose of the utility model can be achieved by the following technical solutions: A new type of automobile seat frame spring frame, characterized in that it includes two cross bars, several tension spring bodies, and hooks fixedly arranged at both ends of the tension spring body, and the hooks are movably clamped on the surface of the cross bar. A plurality of fixing blocks are fixedly connected to the bottom of the cross bar, and a housing is fixedly connected to the bottom of the fixing block. An activity cavity is opened in the housing, an activity plate is slidably arranged in the activity cavity, a spring is arranged between the activity plate and the activity cavity, connecting rods and positioning rods are respectively fixedly connected to both sides of the activity plate, and the connecting rod is located inside the spring. A control rod fixedly connected to the connecting rod is arranged outside the housing, and a positioning groove is opened at the port of the hook, and the positioning rod can be clamped in the positioning groove.
[0006] In the above-mentioned new type of automobile seat frame spring frame, a guiding rod is fixedly connected to the inner side of the hook, and a guiding groove matching with the guiding rod is opened on the surface of the cross bar.
[0007] In the above-mentioned new type of automobile seat frame spring frame, a reinforcing belt is arranged between several tension spring bodies.
[0008] Compared with the prior art, the new type of automobile seat frame spring frame of the utility model can limit and fix the hook, so that when the tension spring body bears the downward pressure of the user, the hook is not easily deformed, and the service life of the hook is prolonged. Brief Description of the Drawings
[0009] Figure 1 It is a three-dimensional schematic diagram of the novel automobile seat frame spring.
[0010] Figure 2 It is a schematic diagram of the hook structure of the novel automobile seat frame spring.
[0011] In the figure, 1 is the cross bar; 2 is the tension spring body; 3 is the hook; 4 is the fixed block; 5 is the housing; 6 is the movable cavity; 7 is the movable plate; 8 is the spring; 9 is the connecting rod; 10 is the positioning rod; 11 is the control rod; 12 is the positioning groove; 13 is the guide rod; 14 is the guide groove; 15 is the reinforcing belt. Specific embodiments
[0012] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.
[0013] As Figure 1 、 2 shown, the novel automobile seat frame spring includes two cross bars 1, a plurality of tension spring bodies 2 and hooks 3 fixedly arranged at both ends of the tension spring body 2, and the hooks 3 are movably clamped on the surface of the cross bar 1. A plurality of fixed blocks 4 are fixedly connected to the bottom of the cross bar 1, and a housing 5 is fixedly connected to the bottom of the fixed block 4. A movable cavity 6 is opened in the housing 5, a movable plate 7 is slidably arranged in the movable cavity 6, a spring 8 is arranged between the movable plate 7 and the movable cavity 6, and a connecting rod 9 and a positioning rod 10 are respectively fixedly connected to both sides of the movable plate 7, and the connecting rod 9 is located inside the spring 8. A control rod 11 fixedly connected to the connecting rod 9 is arranged outside the housing 5. A positioning groove 12 is opened at the port of the hook 3, and the positioning rod 10 can be clamped in the positioning groove 12. The cross bar 1 is a component on the seat frame for installing the tension spring body 2, and the tension spring body 2 is hooked on the cross bar 1 through the hook 3. The movable plate 7 is supported by the acting force of the spring 8, so that the positioning rod 10 is clamped in the positioning groove 12 at the port of the hook 3, achieving the effect of limiting and fixing the hook 3, so that when the tension spring body 2 bears the downward pressure of the user, the hook 3 is not easily deformed. When it is necessary to disassemble the tension spring body 2, pull the control rod 11 to make the positioning rod 10 disengage from the positioning groove 12, and then make the hook 3 disengage from the cross bar 1.
