[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] The present invention provides Figures 1 to 5 A quick-detachable circuit board for new energy vehicles shown in the figure comprises a circuit board 1 and a mounting base 2 located at both ends of the circuit board 1, two sets of fixing bases 3 are fixed on the top of the mounting base 2, a connecting crankshaft 4 is rotatably connected to the opposite side of the fixing base 3 through a bearing, a connecting base 5 is fixed to the opposite end of the connecting crankshaft 4, a receiving groove 6 for clamping the two ends of the circuit board 1 is provided on the surface of the connecting base 5, a contact 7 corresponding to the pin on the circuit board 1 is provided in the inner cavity of the receiving groove 6, an end of the connecting crankshaft 4 away from the connecting base 5 passes through the inner cavity of the fixing base 3 and is fixed with an adjusting gear 8, a rack plate 9 meshing with the adjusting gear 8 is movably provided on the top of the fixing base 3, and a limiting component 10 for limiting the rack plate 9 is provided in the inner cavity of the fixing base 3;

[0024] The adjusting gear 8 is driven to rotate by the rack plate 9, and then the connecting crankshaft 4 is used to rotate the connecting seat 5, so that the orientation of the storage slot 6 is changed, so that the circuit board 1 can be installed and removed. When removing the circuit board 1, it is only necessary to move the limit assembly 10 to make the connecting seat 5 resume rotation, move the circuit board 1 outward, and rotate the connecting seat 5 to achieve the separation of the circuit board 1 and the connecting seat 5, avoiding the need for the traditional circuit board 1 to be exposed to the electric soldering iron for heating during removal. This method is more convenient and quick.

[0025] The limiting assembly 10 includes a square groove 101 opened on the side of the rack plate 9, and a supporting spring 102 is fixed to the inner cavity of the square groove 101. A limiting member 103 is fixed to one end of the supporting spring 102. The one end of the limiting member 103 away from the supporting spring 102 penetrates to the outside of the rack plate 9, and a limiting groove 104 engaged with the limiting member 103 is opened on one side of the inner cavity of the fixing seat 3. The supporting spring 102 supports the limiting member 103. When the rack plate 9 moves in the fixing seat 3 and the limiting member 103 is aligned with the limiting groove 104, the limiting member 103 penetrates into the limiting groove 104 under the action of the supporting spring 102, and limits the rack plate 9 to prevent the connecting crankshaft 4 and the connecting seat 5 from rotating again, causing the circuit board 1 to separate from the connecting seat 5.

[0026] The outer side of the connecting seat 5 is threadedly connected to a limiting bolt 11, which passes through the inner cavity of the receiving groove 6 and fits the outer surface of the circuit board 1. The limiting bolt 11 and the contact 7 are located on both sides of the connecting seat 5. The circuit board 1 can be limited by the limiting bolt 11 so that the circuit board 1 fits the contact 7 to ensure the stability of the connection.

[0027] A moving block 12 is fixed on the surface of the limiting member 103, and a moving groove 13 is opened on the surface of the rack plate 9. The end of the moving block 12 away from the limiting member 103 passes through the moving groove 13 and slides in the moving groove 13. Through the setting of the moving block 12, it is convenient to move the limiting member 103 out of the limiting groove 104 and retract it into the square groove 101, so as to facilitate the movement of the rack plate 9.

[0028] In order to ensure the stability of the contact between the circuit board 1 and the contact 7, another connection scheme is provided, such as Figure 6 As shown:

[0029] The inner cavity of the storage groove 6 is provided with multiple groups of grooves 14, and the inner cavity of the groove 14 is movably connected with a movable block 15 through a movable shaft. The contact 7 is fixed to the surface of the movable block 15, and the inner cavity of the groove 14 is fixed with an adjusting spring 16 connected to the movable block 15. The movable block 15 is supported by the adjusting spring 16 to ensure that the movable block 15 drives the contact 7 to contact the circuit board 1 in the storage groove 6, thereby preventing the circuit board 1 from shaking in the storage groove 6.

[0030] A positioning block 17 is fixed to the inner cavity of the storage groove 6, and positioning grooves 18 aligned with the positioning block 17 are provided at both ends of the circuit board 1. The arrangement of the positioning block 17 and the positioning groove 18 facilitates the positioning of the circuit board 1 to prevent the circuit board 1 from being misaligned with the contact 7, which would cause the circuit board 1 to be unable to complete the electrical path.

[0031] The thickness of the storage groove 6 is greater than that of the circuit board 1. A connecting line extending outwardly and connected to the contact 7 is provided on the outer side of the connecting seat 5. By limiting the size of the storage groove 6, it is ensured that the circuit board 1 enters the storage groove 6 more smoothly when the connecting seat 5 rotates.

[0032] When in use, the circuit board 1 is aligned with the upper end of the connecting seat 5 so that the two ends of the circuit board 1 are located above the receiving groove 6, and then the two ends of the circuit board 1 are pressed downward along the receiving groove 6. The connecting seat 5 rotates under the action of the connecting crankshaft 4, and the circuit board 1 enters the receiving groove 6 as the connecting seat 5 rotates. Then the connecting crankshaft 4 drives the adjusting gear 8 to rotate, and the adjusting gear 8 drives the rack plate 9 to move. After the circuit board 1 is parallel to the receiving groove 6, the limit member 103 is supported by the supporting spring 102 and then bounces into the limit groove 104 to limit the rack plate 9, ensuring the stability of the circuit board 1 and preventing the connecting seat 5 from rotating again. The installation of the circuit board 1 is completed. When the circuit board 1 needs to be removed, it is only necessary to move the moving block 12 to retract the limit member 103 from the limit groove 104, move the rack plate 9 to drive the adjusting gear 8, and reversely drive the connecting seat 5 to release the circuit board 1.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
