Description

Technical Field

[0001] The present invention belongs to the technical field of automotive parts, and particularly relates to a car tailgate spring with stable movement. Background Art

[0002] A spring is a mechanical part that utilizes elasticity. A part made of elastic material deforms under the action of an external force and returns to its original state after the external force is removed. Generally, it is made of spring steel. Springs are complex and diverse in types. Classified by shape, there are mainly helical springs, scroll springs, leaf springs, special-shaped springs, etc.

[0003] However, after the existing tailgate springs are used for a long time, their elasticity decreases, resulting in abnormal closing of the tailgate. Since the installation position is relatively narrow, it is inconvenient to install, disassemble and replace. Therefore, we propose a car tailgate spring with stable movement.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1 - 3, the present invention provides a car tailgate spring with stable movement, including a mounting seat 1. An installation bolt 2 is provided inside the mounting seat 1. A first connecting block 3 is fixedly installed on one side of the mounting seat 1. The first connecting block 3 is movably connected to a second connecting block 5 through a rotating shaft 4. A fixing block 6 is fixedly connected to one side of the second connecting block 5. A mounting block 7 is fixedly connected to one side of the fixing block 6. A first mounting plate 8 is provided on one side of the mounting block 7. A first circular hole 16 is provided inside the mounting block 7. A second circular hole 17 is provided inside the first mounting plate 8. A fastening bolt 18 is provided inside the first circular hole 16 and the second circular hole 17. A second mounting plate 9 is provided on one side of the first mounting plate 8. A telescopic rod 10 is fixedly installed between the first mounting plate 8 and the second mounting plate 9. A first spring 11 is sleeved on the outer wall of the telescopic rod 10. Both ends of the first spring 11 are fixedly connected to the first mounting plate 8 and the second mounting plate 9 respectively. A sleeve 12 is fixedly installed on one side of the second mounting plate 9. A support rod 13 is inserted into the sleeve 12 in a movably connected manner. A limiting block 14 is fixedly connected to one end of the support rod 13 located inside the sleeve 12. A second spring 15 is fixedly installed between one side of the limiting block 14 and the second mounting plate 9.

[0021] In this embodiment, preferably, both the sleeve 12 and the second spring 15 are provided with two and are symmetrically distributed. By providing two second springs 15, the supporting effect of the second spring can be increased, avoiding insufficient supporting force when the trunk is lifted, resulting in the trunk being unable to be lifted.

[0022] In this embodiment, preferably, a third spring 19 is sleeved on one side of the support rod 13 located outside the sleeve 12. Both ends of the third spring 19 are fixedly connected to one end of the two sleeves 12, avoiding damage caused by the collision of the two sleeves 12 when the device contracts.

[0023] In this embodiment, preferably, through holes are provided inside both the first connecting block 3 and the second connecting block 5, facilitating the installation and disassembly of the rotating shaft 4.

[0024] In this embodiment, preferably, a threaded groove is provided inside the second circular hole 17. The fastening bolt 18 forms a threaded connection with the second circular hole 17 through the threaded groove, facilitating the fixation of the mounting block 7 and the first fixing plate 8.

[0025] In this embodiment, preferably, multiple groups of first springs 11 are provided. When in use, the first springs 11 first bear the tensile force, avoiding the direct action of the tensile force on the second springs 15 and affecting the elasticity of the second springs 15.

[0026] In this embodiment, preferably, anti-rust and pressure-reducing coatings are coated on the outer surfaces of the first spring 11, the second spring 15, and the third spring 19, which can further increase the overall service strength and toughness of the springs and more effectively prevent the situation of damage caused by rusting due to the long-term contact of the springs with air.

[0027] Working principle and usage process of the present invention: When this device is in use, before use, first check the safety of each component and each structure inside the tailgate spring of this vehicle, and then assemble the tailgate spring of this vehicle. After the assembly is completed, carry it to the usage location for installation work. During installation, install the two mounting seats 1 on the inside of the trunk and the vehicle body respectively through the mounting bolts 2, and then use it normally. During the actual opening and closing of the trunk, the first connecting block 3 and the second connecting block 5 cooperate with each other to play a role in adapting to the angle and direction of opening and closing. When the trunk is locked with the vehicle body, the support rod 13 presses the second spring 15. When the trunk is opened with the vehicle body, the elastic force generated by the two second springs 15 pops out the support rod 13 to lift the trunk. By providing two sleeves 12, and the second springs 15 are arranged inside both of the two sleeves 12, it is avoided that the second spring 15 has insufficient elasticity after long-term use, resulting in abnormal closing of the tailgate. A plurality of first springs 11 are arranged between the first mounting plate 8 and the second mounting plate 9. During use, the first springs 11 first bear the tensile force, avoiding the tensile force directly acting on the second spring 15 and affecting the elasticity of the second spring 15. It is also very convenient to perform maintenance inspection and replace components when the spring is damaged. By removing the mounting bolts 2, installation and disassembly can be carried out. By coating an anti-rust and pressure-reducing coating on the outer surfaces of the first spring 11, the second spring 15 and the third spring 19, the overall service strength and toughness of the spring can be further increased, and it can more effectively prevent the situation that the spring is easily rusted and damaged due to long-term contact with air.

[0028] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
