DETAILED DESCRIPTION

[0025] Embodiments of the present application are described in detail below with reference to the accompanying drawings, wherein the same or similar notations used throughout the drawings and the specification denote the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary only, and are used only for the purpose of explaining the present application, and should not be understood as limiting the present application.

[0026] Reference Signs: Figures 1-5 The battery plug-in mechanism 307 according to an embodiment of the present application is described below.

[0027] The battery plug-in mechanism 307 according to an embodiment of the present application can be arranged at an end of the battery storage device 302 opposite the battery insertion end 305, and the battery plug-in mechanism 307 includes an electric connector mounting rack 312, an electric connector positioning plate 313, and an elastic return member 314.

[0028] Specifically, the electric connector 321 is arranged through the electric connector mounting rack 312, the electric connector mounting rack 312 has a horizontal adjustment mechanism 315 and a pitch angle adjustment mechanism 316, the electric connector mounting rack 312 is connected to the electric connector positioning plate 313, the electric connector positioning plate 313 is movable forward and backward relative to the electric connector positioning plate 313, one end of the elastic return member 314 is connected to the electric connector 321, and the other end of the elastic return member 314 is connected to the electric connector mounting rack 312.

[0029] Further, when the power battery is placed on the battery storage device 302, the power battery can be charged through the electric connector 321, and the battery plug mechanism 307 can adjust the position of the electric connector 321 relative to the power battery so as to match the power battery with the electric connector 321.

[0030] It should be noted that when the power battery is placed on the battery storage device 302, the charging port of the power battery is not necessarily directly opposite to the electric connector 321, and thus the position of the power battery relative to the electric connector 321 needs to be adjusted. The electric connector 321 is connected with the electric connector mounting frame 312, and the electric connector mounting frame 312 is provided with a horizontal adjustment mechanism 315 and a pitch angle adjustment mechanism 316. The horizontal adjustment mechanism 315 can adjust the charging port of the power battery in the horizontal direction, and the pitch angle adjustment mechanism 316 can adjust the pitch angle of the charging port of the power battery.

[0031] It can be understood that the horizontal adjustment mechanism 315 and the pitch angle adjustment mechanism 316 both adjust the position of the electric connector mounting frame 312 relative to the power battery, that is, the position of the power battery is taken as the reference of the position of the electric connector mounting frame 312 during the adjustment.

[0032] The electric connector positioning plate 313 can well position the electric connector 321, and the position of the electric connector 321 relative to the battery storage device 302 does not change during the adjustment of the position of the power battery. By matching the power battery with the horizontal adjustment mechanism 315 and the pitch angle adjustment mechanism 316, the power battery can be matched with the electric connector 321. During the adjustment, the position of the electric connector mounting frame 312 changes relative to the electric connector positioning plate 313, and after the power battery is taken out of the battery storage device 302, the electric connector mounting frame 312 is reset under the action of the elastic reset member 314, so that the position of the electric connector mounting frame 312 can be adjusted when the electric connector mounting frame 312 is matched with the power battery again.

[0033] The battery plug mechanism 307 according to the embodiment of the application can adjust the position of the electric connector 321 relative to the power battery so as to match the charging port of the power battery with the electric connector 321, and the adjustment mode of the horizontal adjustment mechanism 315 and the pitch angle adjustment mechanism 316 is simple and effective, and the charging port can be quickly aligned with the electric connector 321, so that the power battery can be automatically charged without human intervention.

[0034] In some embodiments of the present application, the front end of the horizontal adjustment mechanism 315 is forward of the front end of the pitch angle adjustment mechanism 316. Thus, in the process of the power battery contacting and fitting with the electric connector 321, the power battery will first contact with the horizontal adjustment mechanism 315, and the horizontal adjustment mechanism 315 adjusts the power battery in the horizontal direction to align the charging port of the power battery, so that the charging port of the power battery is opposite to the electric connector 321 in the horizontal direction.

[0035] It can be understood that the charging port is usually configured to extend in the horizontal direction, so that the angle of the charging port in the horizontal direction needs to be adjusted may be greater than the pitch angle in the vertical direction, so that the direction of the charging port of the power battery is first adjusted to the side of the electric connector 321, so that the charging port is then adjusted in the pitch angle by the pitch angle adjustment mechanism 316 and fitted with the electric connector 321.

[0036] In some embodiments of the present application, the horizontal adjustment mechanism 315 is arranged at both ends of the electric connector mounting frame 312, and the pitch angle adjustment mechanism 316 is located between the two horizontal adjustment mechanisms 315. Among them, the pitch angle adjustment mechanism 316 mainly adjusts the pitch angle of the charging port of the power battery by a small angle.

[0037] Optionally, the pitch angle adjustment mechanism 316 is two, and the two pitch angle adjustment mechanisms 316 are arranged adjacent to the electric connector 321 and are respectively located on both sides of the electric connector 321, so that the matching effect of the pitch angle adjustment mechanism 316 and the power battery can be ensured, and the adjustment accuracy of the pitch angle can be ensured.

[0038] In some embodiments of the present application, the horizontal adjustment mechanism 315 has a first adjustment member 3151 arranged horizontally, and the pitch angle adjustment mechanism 316 includes two second adjustment members 3161 arranged vertically and oppositely in the up-down direction.

[0039] Specifically, when the power battery contacts the first adjustment member 3151, the first adjustment member 3151 guides the power battery in the horizontal direction to align the charging port with the electric connector 321. The two second adjustment members 3161 can guide the power battery well. When the pitch angle of the power battery is upward, the power battery can move downward under the action of the upper second adjustment member 3161 to adjust the pitch angle of the power battery; when the pitch angle of the power battery is downward, the power battery can move upward under the action of the lower second adjustment member 3161 to adjust the pitch angle of the power battery. Thus, the horizontal direction of the power battery can be adjusted by the first adjustment member 3151, and the pitch angle of the power battery can be adjusted by the second adjustment member 3161.

[0040] In further embodiments of the present application, the first adjusting member 3151 and the second adjusting member 3161 are both shaft bearings. Thus, when the first adjusting member 3151 and the second adjusting member 3161 are matched with the power battery, they can abut against the power battery and rotate around the central axis of the bearing to drive the power battery to deflect, thereby achieving the adjustment of the position of the power battery.

[0041] In some embodiments of the present application, the electric connector positioning plate 313 is provided with a sliding groove 317 extending in the front-rear direction, and the sliding part 318 on the electric connector mounting rack 312 is matched in the sliding groove 317. It can be understood that when the pitch angle of the power battery is adjusted, the electric connector mounting rack 312 will produce a certain displacement in the front-rear direction relative to the electric connector positioning plate 313. The sliding groove 317 can guide the movement direction of the electric connector mounting rack 312, and does not interfere with the electric connector mounting rack 312, thereby ensuring the adjustment effect of the battery plug-in mechanism 307 on the position of the power battery.

[0042] In some embodiments of the present application, the battery plug-in mechanism 307 further comprises a positioning plate connecting member 319, and the electric connector positioning plate 313 is pivotally connected to the positioning plate connecting member 319 through a rotating shaft 320. By matching the positioning plate connecting member 319 with the electric connector positioning plate 313, the stability of the electric connector positioning plate 313 in the battery plug-in mechanism 307 can be improved.

[0043] In some embodiments of the present application, the positioning plate connecting member 319 comprises a support plate 3191 and a reinforcing plate 3192. The support plate 3191 is lap-jointed and fixed on the two side beams of the battery storage rack 304, and the reinforcing plate 3192 is fixed on the rear side wall of the support plate 3191. The rotating shaft 320 is rotatably installed on the reinforcing plate 3192. The reinforcing plate 3192 can well reinforce the structural strength of the support plate 3191, and the support plate 3191 has good supporting effect and can be used to support the electric connector 321, thereby improving the stability of the electric connector 321 in the battery plug-in mechanism 307.

[0044] Optionally, when the electric connector 321 rotates by a certain angle around the rotating shaft 320, the support plate 3191 can limit the electric connector 321 from continuing to rotate downward.

[0045] In some embodiments of the present application, the electric connector mounting rack 312 comprises a top plate 3121, a bottom plate 3122 and a connecting plate 3123 connected between the top plate 3121 and the bottom plate 3122, the pitch angle adjusting mechanism 316 has support rods 3162 for supporting the second adjusting members 3161, one of the support rods 3162 is connected with the top plate 3121, the other support rod 3162 is connected with the bottom plate 3122, and the other end of the elastic reset member 314 is connected with the connecting plate 3123.

[0046] Specifically, the support rods 3162 can have good supporting effect on the second adjusting members 3161, and can prevent the two second adjusting members 3161 from moving towards each other, thereby ensuring the adjusting effect of the second adjusting members 3161.

[0047] It can be understood that when the power battery abuts against the second adjusting members 3161, the second adjusting members 3161 will be subjected to certain force while applying force to the power battery, and thus the position of the second adjusting members 3161 relative to the electric connector mounting rack 312 can change, thereby affecting the adjusting accuracy of the second adjusting members 3161.

[0048] In some embodiments of the present application, the elastic reset member 314 is a spring, which has good elastic performance. When the electric connector 321 is matched with the power battery, the elastic reset member 314 will be stretched under force, and when the power battery is removed from the battery plug-in mechanism 307, the electric connector mounting rack 312 will be reset under the action of the elastic reset member 314, so as to ensure that the battery plug-in mechanism 307 is matched with the power battery again.

[0049] In some embodiments of the present application, the battery storage device 302 further comprises a support frame 308, which comprises a plurality of columns 309 and a cross beam 310 connected between the plurality of columns 309 for supporting the battery storage rack 304.

[0050] Further, the cross beam 310 and the plurality of columns 309 of the support frame 308 define a space for arranging the battery storage rack 304, and the support frame 308 has good fixing and supporting effect on the battery storage rack 304, so as to fix the battery storage rack 304 for charging the power battery.

[0051] It can be understood that when the battery storage rack 304 is fixed relative to the support frame 308, the position of the battery storage rack 304 is not easy to change, and when the power battery is matched with the battery storage rack 304, the power battery is easy to be put in, thereby improving the reliability of the battery storage device 302, and facilitating the matching of the power battery with the battery storage device 302.

[0052] As Figure 3 and Figure 4As shown, in some embodiments of the present application, a reinforcing beam 311 is connected between two upright columns 309 close to the moving passage of the battery transfer device 400. The reinforcing beam 311 can serve to improve the structural strength of the support frame 308, thereby improving the reliability of the battery storage device 302.

[0053] Further, the reinforcing beam 311 is connected between the cross beam 310 and the upright column 309, and is arranged obliquely, thereby forming a triangular structure composed of the cross beam 310, the upright column 309 and the reinforcing beam 311 at the support frame 308. The triangular structure is stable and less likely to deform, thereby facilitating the cooperation between the power battery and the battery storage frame 304.

[0054] Optionally, the two ends of the upright column 309 are provided with a pad plate 322, and a plurality of positioning columns 323 are arranged on the pad plate 322, thereby improving the reliability of the battery storage frame 304.
