[0036] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0037] Embodiment 1:

[0038] like Figure 3 , Figure 4 As shown, this embodiment provides a battery locking mechanism, including: a supporting assembly 100 , a rotating assembly 200 and an abutting assembly 300 .

[0039] like Figure 5 As shown, the support assembly 100 of this embodiment includes a connecting plate 110 , a supporting plate 120 connected to the connecting plate 110 and vertically arranged, and a first supporting rod 130 and a second supporting rod 140 connected to the supporting plate 120 .

[0040] The connecting plate 110 is vertically arranged and used to connect with the frame plate with an inlet and outlet of the battery mounting frame 430. The connecting plate 110 is provided with a connecting hole, and the frame plate is provided with a docking hole. The connecting plate 110 and the frame plate can be connected through the connecting hole, the docking hole and bolts and nuts. The connecting plate 110 is installed on the inner side of the frame plate, that is, installed on the side of the frame plate facing the battery.

[0041] The support plate 120 is perpendicular to the connecting plate 110 and is arranged vertically. The support assembly 100 of this embodiment is provided with two support plates 120 arranged in parallel, and the support plates 120 are arranged in an inverted trapezoidal shape. The first support rod 130 is arranged at the outer side of the top of the support plate 120 (the support plate 120 is provided with a first mounting hole that allows the first support rod 130 to pass through), and the first support rod 130 connects the two support plates 120. A limiting structure is provided at the axial end of the first support rod 130 to prevent the first support rod 130 from moving axially and detaching from the support plate 120.

[0042] The second support rod 140 is disposed at a middle position at the bottom of the support plate 120 (the support plate 120 is provided with a second mounting hole allowing the second support rod 140 to pass through), and the second support rod 140 connects and passes through the two support plates 120. Assume that the portion of the second support rod 140 extending out of the left support plate 120 is the left support rod segment, and the portion extending out of the right support plate 120 is the right support rod segment. In this embodiment, the length of the left support rod segment is the same as the length of the right support rod segment.

[0043] In addition, the support assembly 100 of the present embodiment further includes a limit plate 150 connected to the connection plate 110 and arranged horizontally, and the limit plate 150 is located below the free ends of the two support rods 140 .

[0044] The limit plate 150 is perpendicular to the connecting plate 110 and is arranged horizontally. A limit plate 15 is arranged below the free end of the left support rod segment, and a limit plate 15 is also arranged below the free end of the right support rod segment. In order to improve the overall structural strength of the support assembly 100, the length of the limit plate 15 can be appropriately increased, for example, the length of the limit plate 15 can be the same as the length of the left support rod segment (i.e., the right support rod segment).

[0045] In addition, the second support rod 140 is provided with a second assembly ring body 160 between the linkage arm 330 and the rotating arm 210. When the diameter of the second mounting hole of the support plate 120 is larger than the diameter of the second support rod 140, the second assembly ring body 160 can be sleeved on the second support rod 140. The outer diameter of the second assembly ring body 160 is equal to the diameter of the second mounting hole, thereby indirectly realizing the connection between the support plate 120 and the second support rod 140.

[0046] like Figure 6 As shown, the rotating assembly 200 of this embodiment includes a rotating arm 210 connected to the second support rod 140 at the first length direction end, a hand-grip arm 220 connected to the second length direction end of the rotating arm 210, a third support rod 230 connected to the rotating arm 210, a pulling arm 240 connected to the third support rod 230 at the first length direction end, and a fourth support rod 250 connected to the second length direction end of the pulling arm 240.

[0047] The rotating assembly 200 of this embodiment is provided with two rotating arms 210 arranged in parallel, and the hand-grip arm 220 is connected to the two rotating arms 210, and the hand-grip arm 220 and the two rotating arms 210 are integrally formed. A sleeve hole is provided at the first length direction end of the rotating arm 210, wherein the first length direction end of one rotating arm 210 is sleeved with the free end of the left support rod segment through the sleeve hole, and the first length direction end of the other rotating arm 210 is sleeved with the free end of the right support rod segment through the sleeve hole, that is, the two rotating arms 210 can rotate synchronously around the second support rod 140. A limiting structure is also provided at the axial end of the second support rod 140 to prevent the second support rod 140 from axially moving and separating from the support plate 120 and the hand-grip arm 220.

[0048] A third support rod 230 is disposed near the middle of the two rotating arms 210, and the third support rod 230 connects the two rotating arms 210. A limiting structure is disposed at the axial end of the third support rod 230 to prevent the third support rod 230 from axially moving and disengaging from the rotating arms 210.

[0049] The rotating assembly 200 of this embodiment is provided with two parallel pulling arms 240, and a sleeve hole is provided at the first length direction end of the pulling arm 240. The first length direction end of the pulling arm 240 is sleeved with the third support rod 230 through the sleeve hole, so that the two pulling arms 240 can rotate synchronously around the third support rod 230. The fourth support rod 250 is provided at the second length direction end of the pulling arm 240, and the fourth support rod 250 connects the two pulling arms 240. A limiting structure is provided at the axial end of the fourth support rod 250 to prevent the fourth support rod 250 from axially moving and disengaging from the pulling arm 240.

[0050] In addition, the rotating arm 210 is provided with a limit docking surface 211 for abutting against the limit plate 150. The opposite side where the limit plate 150 is connected to the connecting plate 110 is the limit surface. When the battery locking mechanism is in the locked state, the limit docking surface 211 of the rotating arm 210 abuts against the limit surface of the connecting plate 110, and the limit plate 150 can limit the rotating arm 210 from further rotating downward, thereby preventing the abutting assembly 300 from damaging the battery assembly.

[0051] The rotating arm 210 is provided with an escape groove 212 for abutting against the top of the connecting plate 110. An escape notch is provided on the top of the connecting plate 110. When the battery locking mechanism is in an unlocked state, the escape groove 212 of the rotating arm 210 just abuts against the escape notch of the connecting plate 110. At this time, the connecting plate 110 can just support the rotating arm 210, so that the rotating arm 210 will not automatically fall due to gravity, thereby allowing the battery locking mechanism to remain in an unlocked state.

[0052] Furthermore, the third support rod 230 is provided with a first assembly ring body 260 between the two rotating arms 210. When the diameter of the sleeve hole of the pulling arm 240 is larger than the diameter of the third support rod 230, the first assembly ring body 260 can be sleeved on the third support rod 230. The outer diameter of the first assembly ring body 260 is equal to the diameter of the sleeve hole of the pulling arm 240, thereby indirectly realizing the connection between the pulling arm 240 and the third support rod 230.

[0053] like Figure 7 As shown, the abutment assembly 300 of this embodiment includes an abutment frame 310 , an abutment head 320 connected to the abutment frame 310 , and a linkage arm 330 connected to the abutment frame 310 , wherein the linkage arm 330 is connected to the first support rod 130 and the fourth support rod 250 .

[0054] The abutment frame 310 may specifically include a long strip, a mounting protrusion integrally formed with the bottom of the lengthwise end of the long strip, and a butt joint 320 connected to the mounting protrusion. The butt joint 320 is disposed on a first side of the long strip, and the linkage arm 330 is disposed on a second side of the long strip. The first side of the long strip is disposed opposite to the second side of the long strip. When the battery locking mechanism is in a locked state, the butt joint 320 is exactly abutted against the inner side wall of the battery accommodating frame 420.

[0055] In order to improve the overall structural strength of the abutment assembly 300, a reinforcing rib is provided at the connection between the linkage arm 330 and the long strip. The linkage arm 330 is provided with a first through hole and a second through hole. The linkage arm 330 is sleeved on the first support rod 130 through the first through hole, and the linkage arm 330 is sleeved on the fourth support rod 250 through the second through hole. The linkage arm 330 is roughly hook-shaped, and the short side end of the hook-shaped linkage arm 330 is connected to the long strip. The long side end of the hook-shaped linkage arm 330 is provided with a first through hole, and the linkage arm 330 is provided with a second through hole at a position obliquely below the first through hole. The linkage arm 330 can rotate around the first support rod 130 through the first through hole, and the linkage arm 330 can rotate around the fourth support rod 250 through the second through hole. The thickness of the linkage arm 330 can be the same as the distance between the two support plates 120 and the distance between the two pulling arms 240.

[0056] The abutment 320 in this embodiment specifically includes an elastomer and a threaded connecting rod connected to the elastomer. The mounting protrusion is provided with a hole body that allows the threaded connecting rod to pass through. When the abutment 320 is installed, it is only necessary to pass the threaded connecting rod through the hole body and then assemble and connect it with the nut. The disassembly and assembly of the abutment 320 is very simple, which is convenient for later maintenance and replacement. When the abutment 320 is installed, the elastomer is located exactly on the first side of the long strip, and the elastomer is used to abut against the battery accommodating frame 420. On the one hand, the abutment 320 can be prevented from damaging the battery assembly; on the other hand, the elastomer is elastic and can be applied to battery assemblies of different types and sizes, which improves the applicability of the battery locking mechanism.

[0057] The specific working principle of the battery locking mechanism of this embodiment is:

[0058] First, connect the connecting plate 110 of the supporting assembly 100 to the inner side of the frame plate of the battery mounting frame 430 with an inlet and outlet, and make the battery locking mechanism in an unlocked state (i.e. Figure 4 In this embodiment, both racks need to be connected to the battery locking mechanism.

[0059] Then, the battery accommodating frame 420 accommodating the battery body 410 is installed into the battery mounting frame 430 through the inlet and outlet of the battery mounting frame 430 .

[0060] Then, the rotating arm 210 is rotated clockwise downward around the second support rod 140 by holding the arm 220 (in Figure 4 In the perspective of FIG. 1 , the rotating arm 210 drives the third support rod 230, the pulling arm 240, and the fourth support rod 250 to move together during the clockwise downward rotation, thereby enabling the linkage arm 330 to rotate clockwise downward around the first support rod 130 (in FIG. 1 ). Figure 4 ), when the rotating arm 210 rotates to the limiting docking surface 211 and abuts against the limiting plate 150, the linkage arm 330 just drives the abutting frame 310 to move until the abutting head 320 abuts against the inner wall of the battery accommodating frame 420, so that the battery locking mechanism is in a locked state.

[0061] After both battery locking mechanisms are locked, the battery locking mechanism on the left frame plate is used to abut against the left side wall of the battery accommodating frame 420 to prevent the battery accommodating frame 420 from sliding to the right and detaching from the battery mounting frame 430; the battery locking mechanism on the right frame plate is used to abut against the right side wall of the battery accommodating frame 420 to prevent the battery accommodating frame 420 from sliding to the left and detaching from the battery mounting frame 430, thereby achieving the purpose of limiting the battery accommodating frame 420 to the left and right, preventing the battery accommodating frame from automatically sliding out of the inlet and outlet of the battery mounting frame due to vibration and other reasons, and ultimately improving the installation stability of the battery.

[0062] When the battery accommodating frame 420 needs to be removed from the battery mounting frame 430, it is only necessary to rotate the rotating arm 210 counterclockwise upward around the second support rod 140 by hand holding the arm 220 (in Figure 3 From the perspective of FIG. 1 , the rotating arm 210 drives the third support rod 230, the pulling arm 240, and the fourth support rod 250 to move together during the counterclockwise upward rotation, thereby enabling the linkage arm 330 to rotate counterclockwise upward around the first support rod 130 (in FIG. 1 ). Figure 3 ), when the rotating arm 210 rotates to the avoidance groove 212 and abuts against the connecting plate 110, the connecting plate 110 can just support the rotating arm 210, so that the battery locking mechanism can remain in an unlocked state. At this time, the battery locking mechanism will not block the battery accommodating frame 420, and the staff can take the battery accommodating frame 420 out of the inlet and outlet of the battery mounting frame 430.

[0063] Further, such as Figure 3 and Figure 4 As shown, the battery locking mechanism of this embodiment further includes: a fifth support rod and a locking piece 500 .

[0064] The axial end of the fifth support rod is connected to the first support rod 130. The fifth support rod may be directly an extension of the first support rod 130, or may be connected to the first support rod 130 via a connecting member.

[0065] The first length direction end of the locking plate 500 is connected to the fifth support rod. The locking plate 500 is provided with a sleeve hole. The locking plate 500 is sleeved on the fifth support rod through the sleeve hole. The locking plate 500 can rotate around the fifth support rod through the sleeve hole.

[0066] A second lengthwise end of the locking piece 500 is provided with a slot 510 for engaging with the third support rod 230 .

[0067] When the rotating arm 210 is rotated until the battery locking mechanism is in a locked state, the locking plate 500 can be rotated again to engage the locking slot 510 of the locking plate 500 on the third support rod 230. At this time, the locking plate 500 can support the third support rod 230 to prevent the rotating arm 210 from loosening, thereby enabling the battery locking mechanism to be well maintained in a locked state, further improving the installation stability of the battery.

[0068] Embodiment 2:

The battery accommodating frame 420 is used to accommodate the battery body 410, and the battery mounting frame 430 is used to install the battery accommodating frame 420. The connecting plate 110 of the support assembly 100 is used to connect with the battery mounting frame 430, and the abutment head 320 of the abutment assembly 300 is used to abut with the battery accommodating frame 420.
