Technical Field

[0001] The utility model relates to the technical field of automobile battery replacement, in particular to a self-resetting shielding device. Background Art

[0002] With the rapid development of new energy battery-swap heavy trucks, higher requirements are placed on the design of automotive dustproof parts. In the current environment of large-scale cost reduction, a dustproof device with a simple structure, low price, outstanding dustproof effect and no impact on the battery-swap function is more popular with customers.

[0003] The car battery replacement system distributes power on demand according to the number of batteries. The highly efficient automatic battery replacement system can complete the battery replacement in just a few minutes, greatly improving transportation efficiency. In recent years, new energy vehicles have emerged, and high-end models have also developed towards automation. The prospects for fast battery replacement systems are also very broad. Since the actual use of battery replacement has the characteristics of fast speed and continuous battery replacement, it is necessary to design a dustproof device that can match it.

[0004] For the battery replacement system of the car, the dustproof structure is inevitable. For the previous chassis design, a driving function needs to be added, such as a mobile dust cover. This mobile dustproof solution is costly, difficult to disassemble, and easy to accumulate dust. And when the car is replaced with a battery, the dust cover needs to be opened first, which increases the time for battery replacement. And in the current environment of large cost reduction, it is gradually abandoned.

[0005] At present, a self-resetting shielding device can automatically retract and reset. This device has a simple structure, and its automatic reset function can greatly reduce the battery replacement time. The present invention relates to the technical field of automotive battery replacement accessories, and in particular to a sealed shielding cover for battery replacement. Developing a dustproof device with compact design, simple structure, strong applicability, overall beauty, small footprint, and low cost to meet the development needs of new energy battery replacement heavy trucks has become an inevitable trend in the industry.

DETAILED DESCRIPTION

[0022] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. Example 1

[0023] A self-resetting shielding device, as shown in the figure, includes a cover plate 1, a cover plate hole 11 is provided on the cover plate 1, a telescopic plate 3 cooperating with the cover plate hole 11, and a torsion spring 4 installed on the cover plate 1, the working end of the torsion spring 4 contacts with the telescopic plate 3 and pushes the telescopic plate 3 to be pressed against the cover plate hole 11.

[0024] In the closed state, the telescopic plate 3 presses against the rubber ring 2 at the edge of the cover plate hole 11, which can effectively solve the problem of external dust and debris accumulating and entering.

[0025] In the open state, the telescopic plate 3 is pushed open by the driving member b to the outside of the cover plate hole 11, and the driving member b starts to work, which can effectively solve the problem of long battery replacement time for heavy trucks. After the work is completed, the driving member b withdraws and the telescopic plate 3 automatically resets to the closed state. Example 2

[0026] The embodiment is the same as the first embodiment, except that a flanged protrusion 12 is provided on the side where the cover plate hole 11 contacts the telescopic plate 3 .

[0027] A sealing rubber ring 2 is provided on the flange protrusion 12 , and the telescopic plate 3 is in contact with and cooperates with the sealing rubber ring 2 .

[0028] When the car is running, considering that the vehicle will vibrate, abnormal noise is easy to occur when the cover plate 1 is closed. A flange protrusion 12 is designed on the cover plate hole 11, and a sealing rubber ring 2 can be attached to this structure to prevent abnormal noise caused by vibration.

[0029] The telescopic plate 3 is a circular plate. Example 3

[0030] The embodiment 1 is the same as that of the embodiment 1, except that it also includes a support frame 7 fixed on the cover plate 1, on which a bolt 5 is installed, and a torsion spring 4 is sleeved on the bolt 5, one end of the torsion spring 4 contacts the wall surface of the cover plate 1, and the other end of the torsion spring 4 contacts the telescopic plate 3.

[0031] The torsion spring 4 is fixed to the support frame 7 by means of a bolt 5 and the nut 6. The bolt 5 is an external hexagonal bolt. During installation, the bolt 5 is appropriately coated with thread glue to increase the life of the thread, thereby extending the life of the above-mentioned shielding mechanism.

[0032] A positioning groove 71 is provided on the support frame 7 , and one end of the torsion spring 4 that contacts the wall surface of the cover plate 1 cooperates with the positioning groove 71 .

[0033] During installation, the support frame 7 is fixed on the cover plate 1 by spot welding, and the position of the telescopic plate 3 is controlled by the mounting holes on the support frame 7 . Example 4
