[0036] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. The embodiments in the application and the features in the embodiments can be combined with each other without conflict. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0037] Please refer to Figures 1-5 The utility model discloses a spring piece contact type battery charging structure, sets up in charging station 01, including:

[0038] Contact part 1, the contact part 1 sets up on mobile trolley 02;

[0039] Power supply part 2, the power supply part 2 sets up in charging station 01, to contact with contact part 1 and charges mobile trolley 02;

[0040] The contact part 1 includes two groups of parallel contact pieces along the moving direction of mobile trolley 02;

[0041] The power supply part 2 includes two groups of conductive spring pieces 21 corresponding to contact piece respectively, two groups of conductive spring pieces 21 are bent and set up and extend to the contact piece route, to make conductive spring piece 21 contact with contact piece when mobile trolley 02 runs to the corresponding position.

[0042] In the present application, the power supply part 2 further comprises a power supply unit, the positive and negative poles of which are connected with the two groups of conductive spring sheets 21 respectively;

[0043] The mobile trolley 02 is provided with a battery, the positive and negative poles of which are connected with the contact sheets respectively.

[0044] It should be noted that the mobile trolley is provided with a controller and other related electrical elements. Since the above-mentioned technology is a routine technical means that can be easily thought of by those skilled in the art, it is not described in detail.

[0045] It should be further noted that the conductive spring sheet 21 is composed of a metal spring sheet with good conductivity and elasticity, and the contact sheet is made of graphene and arranged on the mobile trolley 02.

[0046] When the mobile trolley 02 moves along the guide rail into the charging station 01, the conductive spring sheet 21 arranged in the charging station 01 shrinks under the extrusion of the trolley. The mobile trolley 02 continues to move until the conductive spring sheet 21 contacts the contact part 1 on the mobile trolley 02. At this time, under the elastic force of the conductive spring sheet 21, the conductive spring sheet 21 continuously and closely contacts the contact sheet, thereby providing a stable and fast power supply environment.

[0047] It should be further noted that, in order to avoid the phenomenon of short circuit during the contact between the conductive spring sheet 21 and the body of the mobile trolley 02, the surface of the mobile trolley 02 is provided with an insulating film 11.

[0048] The insulating film 11 is arranged on both sides of the mobile trolley 02 along the horizontal direction of the contact part 1.

[0049] In another preferred embodiment, as shown in the figure, one group of the conductive spring sheet 21 is provided with a telescopic assembly. Figures 3-5

[0050] The telescopic assembly is used to adjust the bending degree of the conductive spring sheet 21. The conductive spring sheet 21 provided with the telescopic assembly does not contact the contact sheet in the untriggered state.

[0051] The mobile trolley 02 is provided with a lever assembly 12, which is arranged above the contact part 1 and is used to trigger the telescopic assembly when the contact part 1 corresponds to the power supply part 2. The lever assembly 12 is used to contact the telescopic assembly, trigger the telescopic assembly to make the conductive spring sheet 21 bend and extend to contact the contact sheet.

[0052] ​Preferably, the telescopic assembly comprises two groups of translation sliders 22, the two groups of translation sliders 22 are slidingly arranged in the power supply part 2, and the two groups of translation sliders 22 are fixedly connected with two ends of the conductive elastic sheet 21 respectively. It should be noted that the power supply part 2 is provided with moving sliding grooves corresponding to the translation sliders 22, and in the normal state, the conductive elastic sheet 21 elastically pushes the two groups of translation sliders 22 to the two ends of the moving sliding grooves;

[0053] The driven rod 23 is arranged between the two groups of translation sliders 22 and extends out of the power supply part 2.

[0054] The hinged rod 24 is composed of two groups of two mutually hinged connecting rods, and the translation sliders 22 are used to hinge the driven rod 23 with the two groups of translation sliders 22.

[0055] The two groups of hinged rods 24 are each composed of two mutually hinged connecting rods.

[0056] Preferably, the lever assembly 12 comprises a telescopic rod, and one side of the telescopic rod towards the contact part 1 is provided with an inclined surface for contacting the driven rod 23.

[0057] It should be noted that the reset spring is used to abut against the telescopic rod to make it in the extended normal state.

[0058] Based on the above structure, when the moving trolley 02 moves into the charging station 01, the moving trolley 02 body first contacts the conductive elastic sheet 21, and one group of the conductive elastic sheet 21 is in the retracted state, so as to effectively avoid the occurrence of short circuit.

[0059] With the continuous movement of the moving trolley 02, when the contact part 1 on the moving trolley 02 moves to the corresponding position of the power supply part 2, the lever assembly 12 contacts the driven rod 23, the lever assembly 12 pushes the driven rod 23 to translate towards the moving direction of the moving trolley 02, at this time, one group of the hinged rod 24 is folded, and the other group of the hinged rod 24 pulls the translation slider 22 to move, so that the distance between the two groups of translation sliders 22 becomes smaller, thereby causing the conductive elastic sheet 21 arranged on the two groups of translation sliders 22 to bend and protrude and contact the contact part 1, realizing the connection of the charging position.

[0060] After the charging is completed, the moving trolley 02 continues to move, the conductive elastic sheet 21 bends and protrudes and abuts against the contact part 1, and in this process, the elastic force of the conductive elastic sheet 21 continuously increases, until the elastic force of the conductive elastic sheet 21 is greater than the elastic force of the reset spring, thereby pushing the lever assembly 12 to retract through the inclined surface, the lever assembly 12 is separated from the driven rod 23, and then the conductive elastic sheet 21 pushes the two groups of translation sliders 22 to reset, and the conductive elastic sheet 21 is in the retracted state again.

[0061] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative positional relationship, movement condition, etc. between the components in a certain specific posture (as shown in the drawings), and if the specific posture changes, the directional indications will also change accordingly.

[0062] In addition, if the embodiments of the present application involve descriptions such as "first", "second", etc., the descriptions of "first", "second", etc. are only for description purposes and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features with "first" and "second" can explicitly or implicitly include at least one of the features. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of ordinary skilled in the art, and when the combination of technical solutions is contradictory or cannot be realized, it should be considered that the combination of technical solutions does not exist and is not within the protection scope required by the present application.

[0063] In addition, "multiple" means more than two.

[0064] The above is only a preferred embodiment of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
