[0035] The battery positioning and locking device provided by the embodiments of the utility model will be described in detail below in combination with the drawings through some embodiments.

[0036] Referring to Figures 1-9 According to the battery box positioning and locking device provided by the embodiments of the utility model, the electric device comprises:

[0037] The battery assembly is detachably connected to the electric device, and the battery assembly comprises a battery carrier 100 and a battery. The locking mechanism comprises a first lock seat 201, a second lock seat 205 and a manual locking piece, the first lock seat 201 is arranged on the electric device, the second lock seat 205 is arranged on the battery carrier, one end of the manual locking piece is hinged to the first lock seat 201, and the other end of the manual locking piece is movably connected to the second lock seat 205.

[0038] The positioning mechanism comprises a positioning piece and a positioning seat 301, the positioning seat 301 is arranged on the electric device A, and the positioning piece is arranged on the battery carrier 100.

[0039] The battery carrier 100 comprises a bottom surface, the battery carrier 100 is provided with a containing cavity, and the battery is fixed in the containing cavity. The positioning mechanism restricts the movement of the battery assembly along the direction parallel to the bottom surface, and the locking mechanism locks the battery assembly to restrict the movement of the battery assembly along the direction perpendicular to the bottom surface.

[0040] It can be understood that the electric device needs a battery to provide energy, and the battery carrier 100 is an auxiliary device for providing the battery to the electric device.

[0041] Preferably, the battery carrier is provided with a receiving cavity, and the battery is arranged in the receiving cavity, and the receiving cavity is provided with a bottom surface arranged at the bottom of the battery carrier 100 and bearing the battery.

[0042] The embodiment of the utility model takes mine electric vehicle as an example to explain the battery positioning and locking equipment. It can be understood that the battery assembly can be applied to other electric devices in addition to the mine electric vehicle. The electric vehicle is provided with a preset position matched with the battery assembly. The battery assembly is detachably connected with the electric vehicle, so as to replace the power supply.

[0043] It should be noted that there are various connection and charging modes of the battery and the electric device in the prior art, which can be direct contact charging or charging through power transmission line. In some possible embodiments, the battery is fixed in the battery carrier 100, and the battery carrier 100 is provided with a through hole for connecting and charging the battery and the electric vehicle. It should be noted that the battery is fixed in the battery carrier 100, and the fixing can be achieved by welding, fusion, bonding, clamping, screwing, inserting and the like.

[0044] The positioning mechanism realizes the positioning of the battery assembly on the electric vehicle, which can be understood as realizing the positioning by cooperation of the positioning member and the positioning seat 301. In combination with Figures 8-9 , the battery carrier 100 includes a bottom surface, and the positioning mechanism limits the movement of the battery assembly in the direction parallel to the bottom surface. It can be understood that the positioning member is clamped into the positioning seat, and the positioning mechanism has a limiting effect, which limits the movement of the battery assembly in the direction parallel to the first plane, and the first plane is the plane where the X-axis and the Y-axis are located.

[0045] The movable connection between the positioning member and the positioning seat 301 can be understood as the positioning member being inserted into or withdrawn from the positioning seat 301. When the positioning member is inserted into or withdrawn from the positioning seat, the installation or removal of the battery assembly on the electric vehicle is realized.

[0046] In addition, in the embodiment, in order to improve the stability of the positioning mechanism in the mine in a harsh environment, the connection between the positioning member and the positioning seat is selected as a mechanical connection mode.

[0047] The positioning seat 301 can be fixed on the electric vehicle by welding, fusion, bonding, screwing and the like.

[0048] It should be noted that the above embodiment provides a preferred positioning mechanism mode, and the structure of the positioning member and the positioning seat can be adjusted according to the actual needs.

[0049] In some possible implementation manners, the battery positioning and locking device provided by the utility model, the locking mechanism comprises a first lock seat 201, a second lock seat 205 and a manual locking part.

[0050] It can be understood that, as shown in Figures 1-4 In some possible implementation manners, the first lock seat 201 is fixed to the electric vehicle, and the fixing can be realized by welding, fusion, bonding, screwing and the like. The second lock seat 205 is fixed to the bearing frame body 100, and the fixing can be realized by welding, fusion, bonding, screwing and the like.

[0051] One end of the manual locking part is hinged to the first lock seat 201, and the other end of the manual locking part is movably connected to the second lock seat 205. It can be understood that the manual locking part can be clamped and tensioned on the second lock seat 205, so as to realize the fixed locking of the battery assembly and the electric vehicle; the manual locking part can also be separated from the second lock seat 205, so as to facilitate the disassembly of the battery assembly from the electric vehicle.

[0052] The manual locking part can be understood as a manually operated locking part, which is not an automatic locking part.

[0053] It can be understood that the positioning mechanism first positions the battery assembly on the electric vehicle, and then the locking mechanism fixes and locks the battery assembly on the electric vehicle, and the action of the locking mechanism can be completed by manual operation.

[0054] It can be understood that, as shown in Figures 8-9 In space, the battery assembly corresponds to three dimensions, and the movement direction of the battery assembly can be measured by X, Y and Z axes in the space system. The battery assembly is fixed on the electric vehicle by the positioning mechanism and the locking mechanism, so that the battery assembly cannot move in the three directions. It can also be understood that the battery assembly cannot move in the parallel direction along the bottom surface and the direction perpendicular to the bottom surface.

[0055] The battery positioning and locking device provided in the embodiment is installed and fixed or disassembled by a manual semi-automatic mode, solves the problem of interference of complex and harsh environmental factors in the prior art, has the technical effects of strong adaptability and convenient disassembly, and the positioning mechanism, the locking mechanism and the battery assembly provided in the embodiment have the technical effects of compact and simple structure, low cost, small occupied space and firm connection of the battery assembly and the electric vehicle.

[0056] Furthermore, according to the battery positioning and locking device provided in this embodiment of the present invention, the positioning seat 301 is provided with a positioning groove, and the positioning member is provided with a connecting conical surface, the connecting conical surface being adapted to the positioning groove. It can be understood that when the positioning member is connected to the positioning seat 301, the connecting conical surface inserts into the positioning groove, thereby achieving the positioning of the battery assembly on the electric vehicle.

[0057] Furthermore, in the battery positioning and locking device provided according to the embodiments of the present invention, the connecting conical surface includes a fixed end and a free end, and the cross-sectional width of the connecting conical surface gradually decreases from the fixed end to the free end.

[0058] like Figures 6-7 As shown, there are various structures for the connecting cone surface. In some embodiments, a first connecting cone surface 303 or a second connecting cone surface 304 is used. This cone surface structure can achieve rough positioning during the battery assembly's descent, and then automatically adjust and align itself as the battery assembly is lowered. Once the battery assembly has completely fallen to its preset position on the electric vehicle, precise positioning can be achieved.

[0059] It should be noted that the continuous automatic adjustment and alignment of the battery pack refers to the process during which the battery pack automatically adjusts to its preset position within the electric vehicle at a certain angle.

[0060] Understandably, the principle behind the continuous automatic adjustment and alignment of the battery pack is that, due to the design of the conical structure, the cross-sectional width of its free end is relatively small, less than the width of the positioning groove. The free end can easily be positioned and enter the positioning groove. As the battery pack is lowered, the width of the connecting conical surface entering the positioning groove becomes larger and larger. The positioning groove causes the connecting conical surface to move in the direction of the angle in which it is tilted towards the electric vehicle. Consequently, the battery pack moves in the direction of the angle in which it is tilted towards the electric vehicle. Finally, the battery pack moves to its preset position on the electric vehicle.

[0061] This embodiment provides two preferred structures for connecting conical surfaces, such as... Figure 6 As shown, the conical surface can have smooth edges, and its front view structure is parabolic. For example... Figure 7 As shown, the conical surface can also have edges formed by stacked trapezoids, with different slopes on the waists of the trapezoids, gradually decreasing from the fixed end to the free end. In both embodiments, the cross-sectional width of the conical surface gradually decreases from the fixed end to the free end.

[0062] In some possible implementations, the positioning element further includes a fixing seat 306, which is connected to the battery carrier 100, and the fixing end of the connecting cone is connected to the fixing seat 306.

[0063] like Figure 5As shown, in some possible embodiments, the positioning member further comprises a fixing seat 306 fixed on the battery carrier 100, and the connecting taper is connected to the fixing seat 306 through the limiting connecting part 302, that is, one end of the limiting connecting part 302 is connected to the fixing seat 306, and the other end is connected to the connecting taper. The connecting taper comprises a fixed end and a free end, wherein the fixed end is connected to the other end of the limiting connecting part 302, and the free end is away from the limiting connecting part 302.

[0064] The limiting connecting part 302 enables the positioning seat 301 to maintain a preset distance from the fixing seat 306, facilitating positioning of the battery assembly.

[0065] In the embodiment, a limiting plate 305 is arranged between the fixed end of the connecting taper and the limiting connecting part 302. When the positioning member is positioned, the limiting plate 305 is in contact with the positioning seat 301, avoiding direct collision of the limiting connecting part 302 with the positioning seat 301, thereby improving the firmness and stability of the positioning mechanism. Meanwhile, the flat plate surface of the limiting plate 305 ensures the accuracy of the positioning direction.

[0066] Further, the battery positioning and locking device provided in the embodiment of the utility model, the manual locking member comprises a locking part and a locking connecting rod, one end of the locking connecting rod is connected with the locking part, and the other end is hinged with the first lock seat 201.

[0067] The arrangement of the locking connecting rod and the hinging of the other end of the locking connecting rod with the first lock seat 201 facilitate the installation and removal of the battery assembly.

[0068] Further, the battery positioning and locking device provided in the embodiment of the utility model, the first end of the locking part is provided with a hollow collar, the second lock seat is provided with a protruding lock buckle, and the hollow collar is movably connected with the second lock seat 205.

[0069] It can be understood that the movable connection means that when the battery assembly is locked, the hollow collar is installed in the lock buckle, and when the battery assembly is removed from the electric vehicle, the hollow collar is taken out of the lock buckle.

[0070] Further, the battery positioning and locking device provided in the embodiment of the utility model, preferably, the locking part is a self-locking type hasp lock 203, the hollow collar 204 comprises a U-shaped adjustable screw rod and a nut, the U-shaped adjustable screw rod can be clamped with the second lock seat 205, the second end of the self-locking type hasp lock is provided with a connecting seat, and one end of the locking connecting rod is connected with the connecting seat.

The hollow sleeve ring is movably connected to the second lock seat 205, that is, the hollow sleeve ring can be taken out of the second lock seat 205 or sleeved and clamped to tighten the second lock seat 205, so as to realize the loosening or locking of the battery assembly in the electric vehicle.
