Description

Technical Field

[0001] The present invention relates to the technical field of automotive mechanical parts, and more particularly to a double spiral spring torsion accumulator and its application. Background Art

[0002] For the cargo box of existing pickup truck models, continuous manual force is required during the opening process to ensure a smooth opening. When closing the cargo box door, a great deal of force is needed to close it, resulting in poor comfort. The present invention redefines and designs a double spiral spring accumulator, which plays a role in assisting during the opening and closing of the cargo box, improving the comfort perception of customers.

[0003] Currently, most pickup truck models are blank in terms of assisting in the opening and closing of the cargo box. Generally, only a pull rope is used to hold the cargo box, but this pull rope generally only serves a limiting function and does not play a role in assisting. Individual models use pneumatic dampers to achieve the effect. As shown in Figure 5 Figure 8, it is often necessary to cooperate with a pull rope. The pull rope and the gas spring are usually installed at the same position. Since the position is narrow, problems such as interference and paint peeling may occur. Moreover, the damper is filled with gas inside, resulting in a short lifespan and easy air leakage. Summary of the Invention

[0004] The purpose of the present invention is to provide a double spiral spring torsion accumulator and its application, which are used to solve the problem that pickup truck models cannot assist in the opening and closing of the cargo box, and for models using pneumatic dampers for assistance, problems such as paint peeling, short lifespan, and easy air leakage of the assistance equipment.

[0005] To achieve the above purpose, the present invention provides a double spiral spring torsion accumulator, including a hinge support. One end of the hinge support is connected to one end of an inner core through a pin shaft. The other end of the inner core is nested with an outer shell. A torsion bending spring is sleeved on the inner core at a position between the outer shell and the hinge.

[0006] Preferably, a guiding spring is arranged inside the torsion bending spring, and the guiding spring penetrates through the torsion bending spring.

[0007] Preferably, a hinge contact block is arranged on the hinge support, and the hinge contact block is connected to the torsion bending spring.

[0008] Preferably, the hinge support is arranged in a T-shaped structure. The hinge support includes a hinge hinge and a fixing device. The fixing device is connected to the vehicle body, and the hinge hinge is connected to the vehicle door.

[0009] Preferably, the fixing device is arranged in an L-shaped structure.

[0010] Preferably, one end of the inner core body away from the hinge support is connected to the vehicle body.

[0011] Preferably, the torsion bending spring is of a double helix structure.

[0012] A double helix spring torsion energy accumulator is applied to a pickup truck cargo box. The double helix spring torsion energy accumulator includes a hinge support. One end of the hinge support is connected to one end of an inner core body through a pin shaft. The other end of the inner core body is nested and connected with an outer shell sleeve. A torsion bending spring is arranged between the inner core body and the outer shell body. A guiding spring is arranged inside the torsion bending spring, and the guiding spring penetrates through the torsion bending spring. A hinge contact block is arranged on the hinge support, and the hinge contact block is connected with the torsion bending spring. The hinge support is arranged in a T-shaped structure and includes a hinge hinge and a fixing device. The fixing device is connected to the vehicle body, and the hinge hinge is connected to the vehicle door. The fixing device is arranged in an L-shaped structure. One end of the inner core body away from the hinge support is connected to the vehicle body. The torsion bending spring is of a double helix structure.

[0013] Therefore, the present invention adopts a double helix spring torsion energy accumulator with the above structure and a pickup truck cargo box to which it is applied. The present invention utilizes the gravitational potential energy of the vehicle door itself during the opening process to be converted into the elastic force of the torsion bending spring, skillfully utilizes the movement itself to convert energy, reduces costs, improves practical durability, and achieves the effect of assisting without consuming external force.

[0023] Embodiment

[0024] A double - helix spring torsion energy accumulator includes a hinge support 1. One end of the hinge support 1 is connected to one end of the inner core body 3 through a pin shaft 5. The other end of the inner core body 3 is nested and connected to the outer shell body 6. A torsion bending spring 2 is sleeved on the inner core body 3 at a position between the outer shell body 6 and the hinge. A guiding spring 4 is arranged inside the torsion bending spring 2, and the guiding spring 4 penetrates through the torsion bending spring 2. A hinge contact block 9 is arranged on the hinge support 1, and the hinge contact block 9 is connected to the torsion bending spring 2. The hinge support 1 is arranged in a T - shaped structure. The hinge support 1 includes a hinge hinge 101 and a fixing device 102. The fixing device 102 is connected to the vehicle body 11, and the hinge hinge 101 is connected to the vehicle door 10. The fixing device 102 is arranged in an L - shaped structure. The end of the inner core body 3 far from the hinge support 1 is connected to the vehicle body 11. The torsion bending spring 2 is of a double - helix structure.

[0025] Among them, the hinge support 1 is the link connecting the cargo door 10 and the vehicle body 11. The opening of the cargo door is completed by the rotation of the hinge hinge. The inner core 3 has spiral grooves inside, providing space for the installation and compression deformation of the spring. Among them, the torsion bending spring 2 is installed in the spiral space formed between the inner core 3 and the outer shell 6. The guiding spring 4 passes through the torsion bending spring 2, providing deformation support and guiding for the torsion spring, and also providing guiding for the hinge contact block 9. The hinge contact block 9 has an opening passing through the guiding spring 4. One end of the inner core 3 is connected to the hinge support 1 through a pin shaft 5, and the other end of the inner core 3 is connected to the vehicle body 11 through a bolt, as Figure 4 . During the opening process of the cargo door 10, the hinge contact block 9 will rotate along with the hinge hinge 101, thus coming into contact with the 2 torsion bending springs. The torsion bending spring 2 will be compressed and deformed along the guiding spring 4, and the spring will generate a reverse resistance, which can gradually increase with the displacement, so as to play a role in assisting the opening of the door. During the closing process of the cargo door 10, the compressed torsion bending spring 2 will slowly release the energy stored during the opening process, thus playing a role in assisting the closing process. This invention utilizes the conversion of the gravitational potential energy of the vehicle door itself into the elastic force of the torsion bending spring 2 during the opening process of the door, and cleverly utilizes the movement itself to convert energy, achieving the effect of assisting without consuming external force.

[0026] Therefore, the present invention adopts a double-spiral spring torsion energy accumulator with the above structure and its application. By using the elastic force of the torsion bending spring, it utilizes the movement itself to convert energy, achieving the effect of assisting without consuming external force, improving durability, and greatly enhancing the opening and closing feeling of the cargo door of pickup truck models; the overall structural design is small in size, occupies little space, has a simple manufacturing process, reduces the manufacturing cost, and can be applied to many models.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that they can still modify or equivalently replace the technical solutions of the present invention, and these modifications or equivalent replacements cannot make the modified technical solutions deviate from the spirit and scope of the technical solutions of the present invention.
