[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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.

[0023] Please refer to Figure 1-6 , an embodiment provided by the present invention:

[0024] A high-power vehicle-mounted charging circuit board includes a charging circuit board 1. The surface of the charging circuit board 1 is fixedly connected with a first fixing block 2 for connecting the connecting rod 5. The surface of the first fixing block 2 is provided with a sliding groove 3 for the connecting rod 5 to move on the surface of the first fixing block 2. The surface of the charging circuit board 1 is fixedly connected with a second fixing block 4 for connecting the connecting rod 5. The surface of the first fixing block 2 is movably connected with a connecting rod 5 for connecting the cloth belt 9. When moving on the surface of the first fixing block 2, the cloth belt 9 is driven to move. The surface of the connecting rod 5 is fixedly connected with a first limiting piece 6 for restricting the position of the connecting rod 5 at the second fixing block 4 to prevent the connecting rod 5 from detaching from the surface of the second fixing block 4. One end of the connecting rod 5 far from the first limiting piece 6 is fixedly connected with a second limiting piece 7 to prevent the connecting rod 5 from detaching from the surface of the first fixing block 2 and at the same time for connecting the push rod 8. The surface of the second limiting piece 7 is fixedly connected with a push rod 8 for pushing the connecting rod 5 to move, driving the cloth belt 9 to move, and changing the state of the cloth belt 9 so that it can be laid flat for storage or bent and erected. The surface of the connecting rod 5 is fixedly connected with a cloth belt 9. Lifting the cloth belt 9 can conveniently lift the charging circuit board 1 from the vehicle-mounted charger. The surface of the charging circuit board 1 is plugged and connected with a fixing plate 10. After the insertion plate 12 is inserted into the charging circuit board 1, bolts pass through the fixing groove 11 to fix the positions of the fixing plate 10 and the charging circuit board 1. The surface of the fixing plate 10 is provided with a fixing groove 11 for bolts to pass through and be fixed in the vehicle-mounted charger. The surface of the fixing plate 10 is fixedly connected with an insertion plate 12 for inserting into the insertion slot 13 to connect the fixing plate 10 and the charging circuit board 1. The surface of the charging circuit board 1 is provided with an insertion slot 13 for the insertion of the fixing groove 11.

[0025] Further, the connecting rod 5 is in the shape of a round rod, which is convenient for movement. The diameter of the connecting rod 5 is smaller than the width of the sliding groove 3, so that the connecting rod 5 can move in the sliding groove 3, thereby driving the cloth belt 9 to move and changing the state of the cloth belt 9, making it lie flat for storage or bend and stand up for use.

[0026] Further, both the first limiting piece 6 and the second limiting piece 7 are in the shape of discs. The diameter of the first limiting piece 6 is larger than the width of the sliding groove 3, so that during the movement of the connecting rod 5, the connecting rod 5 does not fall off the surface of the second fixing block 4. The diameter of the second limiting piece 7 is larger than the width of the sliding groove 3, so that during the movement of the connecting rod 5, the connecting rod 5 does not fall off the surface of the first fixing block 2.

[0027] Further, the connecting rod 5 is movably connected to the surface of the sliding groove 3 through the push rod 8. Moving the push rod 8 can drive the connecting rod 5 to move, thereby driving the cloth belt 9 to move and changing the shape of the cloth belt 9, so that the cloth belt 9 changes from being flat to being bent, which is convenient for lifting the cloth belt 9 to lift the charging circuit board 1.

[0028] Further, the sliding groove 3 is opened on the surface of the second fixing block 4 for the connecting rod 5 to move. The connecting rod 5 is movably connected to the surface of the second fixing block 4 through the sliding groove 3. Moving the push rod 8 drives the connecting rod 5 to move on the surface of the second fixing block 4. The setting of the first limiting piece 6 prevents the connecting rod 5 from falling off the surface of the second fixing block 4.

[0029] Further, two groups of cloth belts 9 are symmetrically distributed on the surface of the charging circuit board 1. The setting of the two groups of cloth belts 9 facilitates lifting the charging circuit board 1 from both sides. The cloth belt 9 is movably connected to the surface of the charging circuit board 1 through the connecting rod 5. The movement of the connecting rod 5 drives the cloth belt 9 to move and changes the state of the cloth belt 9, making it lie flat for storage or bend and stand up for use.

[0030] Further, the fixing plate 10 is inserted and connected to the surface of the slot 13 through the insertion plate 12. The fixing plate 10 is inserted and connected to the surface of the charging circuit board 1 through the slot 13. Insert the insertion plate 12 into the slot 13, and then place the fixing plate 10 at the position where it needs to be installed by bolts, so that the bolts fix the position of the fixing plate 10 through the fixing groove 11, thereby fixing the position of the charging circuit board 1.

[0031] Working principle: When using the charging circuit board 1, insert the fixing plate 10 into the slot 13, then place the charging circuit board 1 at the position where it needs to be installed, and pass a bolt through the fixing groove 11 to tighten and fix the position of the fixing plate 10, thereby fixing the position of the charging circuit board 1. When it is necessary to remove the charging circuit board 1 and replace the fixing plate 10, first remove the fixing bolt, then push the push rod 8 to drive the connecting rod 5 to move, thereby driving the cloth belt 9 to move, changing the cloth belt 9 from the state of being flat and stored to being bent and erected. Then, the cloth belt 9 can be lifted to lift out the charging circuit board 1. Then, pull out the fixing plate 10, insert a new fixing plate 10 into the slot 13, and then place the charging circuit board 1 back in place and fix it with a bolt.

[0032] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present utility model, the present utility model can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model.
