Description

Technical Field

[0001] The present invention relates to the field of battery locking devices, and in particular to a locking device for a power battery. Background Art

[0002] At present, both electric motorcycles and mechanical devices such as drones need to be powered by batteries. Therefore, batteries are an important part of electric motorcycles, providing sufficient power for electric motorcycles. A locking structure is provided on the outside of the battery to fix the battery. The locking structure improves the stability of the battery lock and avoids the phenomenon of battery damage.

[0003] However, when the locking structure is in use, since the connection between the locking structure and the electric motorcycle is a bolt connection, it is more troublesome to disassemble, which reduces the efficiency of installation and disassembly and affects the working hours of the staff. Application No. CN202020818601.4 in the prior art discloses a battery locking structure applied to a drone, which includes a mounting shell, a metal sheet, a card plate, a compression spring, a connecting ring, a fixing frame, a slide groove, a slider, a cover plate, a stop block, a limit plate and a convenient installation device. Although this technical solution realizes a partial locking function of the battery, the locking device lacks lateral locking of the battery, so that the power battery cannot be completely fixed after the battery is installed, which leads to the risk of the battery swinging during the driving of the vehicle, which is not conducive to the driving of the motorcycle. Summary of the invention

[0004] In order to solve the above problems, the present invention provides a locking device for a power battery.

[0005] A locking device for a power battery comprises a seat cushion, a battery locking mechanism assembly, a power battery, a battery locking frame and a frame, wherein the upper end of the battery locking frame is provided with a battery mounting slot for detachably carrying and fixing the power battery, and both sides of the battery locking frame are provided with a first pivot shaft movably hinged to the frame, and the battery locking frame can be movably flipped relative to the first pivot shaft; The battery locking mechanism assembly is movably hinged to the upper end of the frame, and the battery locking mechanism assembly includes a connecting piece articulated to the frame and a positioning clamp fixedly connected to the end of the connecting piece, the connecting piece can be flipped relative to the frame, and the frame locks the lateral displacement of the connecting piece. When the positioning clamp is flipped and pressed down relative to the connecting piece, the positioning clamp and the positioning slot provided on the upper part of the power battery form a locking fit, and the power battery is then locked and fixed obliquely. The positioning clamp is used to lock the flipping freedom and lateral freedom of the power battery. When the positioning clamp is disengaged from the positioning slot, the power battery can be flipped relative to the first pivot to a vertical state to be taken out; the seat cushion is arranged above the connecting piece, and when the positioning clamp is adapted to the positioning slot, the seat cushion and the connecting piece form a press-limit fit, and the seat cushion locks the flipping freedom of the connecting piece.

[0006] Preferably, a battery compartment adapted for a power battery and a battery lock frame is provided in the frame, the battery compartment is arranged obliquely, an outlet for taking out the power battery is provided at the upper end of the battery compartment, an outward opening for turning out the battery lock frame is provided at the lower end of the battery compartment, a handle for users to take out is provided at the upper end of the power battery, when the power battery is turned to a vertical state under the action of gravity, the lower end of the battery lock frame turns out from the outward opening, the upper end of the power battery faces the outlet, and the user can directly take out the power battery by the handle; when the positioning clamp head and the positioning clamp slot are locked against each other, the connecting piece blocks the outlet. The setting of the connecting piece can be used for both the flipping support of the positioning clamp head and the shielding of the outlet.

[0007] Preferably, the connecting member includes a connecting plate and a triangular support frame integrally fixedly arranged at the end of the connecting plate, one end of the connecting plate is fixedly connected to a hinge tube, a transverse hinge assembly is movably sleeved in the hinge tube, the transverse hinge assembly locks the axial displacement of the hinge tube, one side of the triangular support frame is fixedly connected to the connecting plate, and the other side of the triangular support frame is fixedly connected to the back of the positioning clamp. The connection area between the triangular support and the back of the positioning clamp is large, so it has a good stability effect. When the seat cushion achieves a corresponding pressing effect on the connecting plate, the triangular support plate controls the positioning clamp to stably buckle in the positioning slot of the power battery, avoiding the connection plate and the positioning clamp from breaking when pressed.

[0008] Preferably, a transverse fixing column is provided on the frame, a transverse hinge assembly is provided on the upper end of the transverse fixing column, the transverse hinge assembly includes a middle transverse pivot and limit support ends fixedly installed on both ends of the transverse pivot, the transverse pivot is parallel to the transverse fixing column, the transverse pivot is movably sleeved on the hinge tube outside, the upper part of the limit support end is fixedly sleeved on the two ends of the transverse pivot, the lower end of the limit support end is fixedly connected to the transverse fixing column, and the two limit support ends constitute an axial limit mechanism for the hinge tube.

[0010] Preferably, a battery cover is provided on the upper part of the power battery, symmetrical positioning grooves are provided on both sides of the battery cover, a transverse elastic rod is provided in the positioning groove, the positioning slot is provided at the lower part of the transverse elastic rod, and an elastic buffer gap is provided between the transverse elastic rod and the inner wall of the positioning groove. In actual operation, the positioning clamp is buckled in the positioning slot at the lower part of the transverse elastic rod. In actual use, since there will inevitably be corresponding bumps during driving, the elastic buffer effect of the transverse elastic rod will effectively prevent the impact of the positioning clamp on the power battery itself.

[0011] Preferably, the connecting plate is provided with a U-shaped plate portion protruding outward on one side corresponding to the seat cushion, and both ends of the U-shaped plate portion are fixedly connected to the connecting plate. The U-shaped plate portion and the side surface of the connecting plate constitute a lateral sliding groove extending along the length direction of the connecting plate. The bottom of the seat cushion is provided with a locking bottom groove adapted to the connecting plate, and the inner bottom wall of the locking bottom groove is provided with an elastic hook protruding outward, and the elastic hook and the lateral sliding groove constitute a sliding plug-in locking fit.

[0012] Preferably, it also includes a battery cover plate with a movable hinged frame at one end, the battery cover plate flips over and covers the battery locking mechanism assembly, the other end of the battery cover plate is provided with an oblique extension, and the upper end surface of the extension is provided with a limit groove that forms a limit fit with the lower end of the seat cushion.

[0013] Preferably, the elastic hook is an L-shaped hook structure, and the elastic hook includes a connecting part and a horizontal extension part connected to each other. When the seat cushion presses the U-shaped plate part and slides to one side, the transverse elastic rod is bent by force, and the U-shaped plate part fits the inner wall of the bottom groove. When the seat cushion releases the pressing force of the U-shaped plate part, the transverse elastic rod is reset to apply an elastic force to the U-shaped plate part to make it fit the upper surface of the horizontal extension part of the elastic hook. This effect can again utilize the elastic force of the transverse elastic rod to facilitate the sliding insertion of the elastic hook, and can also realize the sliding locking of the elastic hook and the lateral sliding slot through the transverse elastic rod to prevent the elastic hook from sliding relative to the lateral sliding slot during driving.

[0014] Beneficial effect: During the actual driving process, the unique battery locking device of this product can directly transmit the weight of the person to the connector through the upper seat cushion, so that the positioning clamp at the end of the connector can firmly lock the power battery in the positioning slot, effectively preventing the power battery from swinging left and right during driving. When the power battery needs to be removed, the seat cushion is turned over. Since the battery locking mechanism component loses the pressing and limiting function of the seat cushion at this time, the user can easily realize the externalization of the connector.

[0028] The following is combined with Figure 1-12 The present invention is further described with this embodiment.

[0029] like Figure 1-2 As shown, a locking device for a power battery comprises a seat cushion 1, a battery upper cover plate 2, a battery locking mechanism assembly, a power battery 3, a battery locking frame 4 and a frame 5. The upper end of the battery locking frame 4 is provided with a battery mounting slot for detachably carrying and fixing the power battery 3. Both sides of the battery locking frame 4 are provided with a first pivot 6 movably hinged to the frame 5, and the battery locking frame 4 can be movably flipped relative to the first pivot 6.

[0030] like Figure 4-5 As shown, the battery locking mechanism assembly is hinged to the upper end of the frame 5, and the battery locking mechanism assembly includes a connecting member 7 hinged to the frame 5 and a positioning clamp 8 fixedly connected to the end of the connecting member 7. The connecting member 7 can be flipped relative to the frame 5, and the frame 5 locks the lateral displacement of the connecting member 7. When the positioning clamp 8 is flipped and pressed downward relative to the connecting member 7, the positioning clamp 8 and the positioning clamp groove 9 provided on the upper part of the power battery 3 form a locking fit. Figure 4 As shown, the connecting member 7 includes a connecting plate 15 and a triangular support frame 16 integrally fixedly arranged at the end of the connecting plate 15, one end of the connecting plate 15 is fixedly connected to a hinge tube 17, a transverse hinge assembly is movably sleeved in the hinge tube 17, and the transverse hinge assembly locks the axial displacement of the hinge tube 17, one side of the triangular support frame 16 is fixedly connected to the connecting plate 15, and the other side of the triangular support frame 16 is fixedly connected to the back of the positioning clamp 8. The connection area between the triangular support and the back of the positioning clamp 8 is large, so it has a good stability effect. When the seat cushion 1 realizes the corresponding pressing effect on the connecting plate 15, the triangular support plate controls the positioning clamp 8 to stably buckle in the positioning slot 9 of the power battery 3, avoiding the connection plate 15 and the positioning clamp 8 from breaking when pressed. The frame 5 is provided with a transverse fixing column 25, and the upper end of the transverse fixing column 25 is provided with a transverse hinge assembly, and the transverse hinge assembly includes a middle transverse pivot 26 and a limit support end 27 fixedly installed at both ends of the transverse pivot 26, and the transverse pivot 26 is parallel to the transverse fixing column 25. The transverse pivot 26 is movably sleeved on the hinge tube 17, and the upper part of the limit support end 27 is fixedly sleeved on both ends of the transverse pivot 26, and the lower end of the limit support end 27 is fixedly connected to the transverse fixing column 25, and the two limit support ends 27 constitute an axial limit mechanism for the hinge tube 17. At this time, the power battery 3 is flipped relative to the first pivot 6 to a vertical state after losing the support of the positioning clamp 8, and the user can directly take out the power battery 3 conveniently and quickly.

[0031] like Fig. 9As shown, a battery cover 18 is provided on the upper part of the power battery 3, and symmetrical positioning grooves 19 are provided on both sides of the battery cover 18, and a transverse elastic rod 20 is provided in the positioning groove 19. The positioning slot 9 is provided at the lower part of the transverse elastic rod 20, and an elastic buffer gap 21 is provided between the transverse elastic rod 20 and the inner wall of the positioning groove 19. In actual operation, the positioning clamp 8 is buckled in the positioning slot 9 at the lower part of the transverse elastic rod 20. In actual use, since there will inevitably be corresponding bumps during driving, the elastic buffering effect of the transverse elastic rod 20 will effectively prevent the positioning clamp 8 from impacting the power battery 3 itself.

[0032] At this time, the power battery 3 is installed and fixed obliquely, and the positioning clamp 8 is used to lock the flipping freedom and lateral freedom of the power battery 3. When the positioning clamp 8 is disengaged from the positioning slot 9, the power battery 3 can be flipped relative to the first pivot 6 to a vertical state to be taken out; the seat cushion 1 is arranged above the connecting member 7, and when the positioning clamp 8 is adapted to the positioning slot 9, the seat cushion 1 and the connecting member 7 form a press-limiting cooperation, and the seat cushion 1 locks the flipping freedom of the connecting member 7.

[0033] like Figure 8 As shown, the positioning clamp 8 includes a longitudinal portion 81 and a transverse portion 82 that are connected to each other, and the longitudinal portion 81 and the transverse portion 82 form an L-shaped block structure. An outwardly protruding stepped protrusion 83 is provided at the angle where the longitudinal portion 81 and the transverse portion 82 are connected, and the stepped protrusion 83 forms a locking fit with the positioning slot 9. The positioning clamp 8 locks the flipping freedom and lateral freedom of the power battery 3.

[0034] like Figure 5-6 As shown, a battery compartment 11 adapted to the power battery 3 and the battery lock frame 4 is provided in the frame 5. The battery compartment 11 is arranged obliquely, and an outlet 12 for taking out the power battery 3 is provided at the upper end of the battery compartment 11. An external opening 13 for externally turning the battery lock frame 4 is provided at the lower end of the battery compartment 11. A handle 14 for users to take out is provided at the upper end of the power battery 3. When the power battery 3 is turned to a vertical state under the action of gravity, the lower end of the battery lock frame 4 is turned out from the external opening 13, and the upper end of the power battery 3 is facing the outlet 12. Users can directly take out the power battery 3 through the handle 14; when the positioning clamp 8 is pressed against the positioning slot 9 and locked, the connector 7 blocks the outlet 12. Figure 5 and Figure 6 What is shown in the figure is the internal structure without the power battery 3.

[0035] like Figure 4As shown, the connecting plate 15 is provided with a U-shaped plate part 22 protruding outward on one side corresponding to the seat cushion 1, and the two ends of the U-shaped plate part 22 are fixedly connected to the connecting plate 15. The U-shaped plate part 22 and the side of the connecting plate 15 form a lateral sliding groove 23 extending along the length direction of the connecting plate 15. The bottom of the seat cushion 1 is provided with a clamping bottom groove 24 adapted to the connecting plate 15, and the inner bottom wall of the clamping bottom groove 24 is provided with an elastic hook 10 protruding outward, and the elastic hook 10 and the lateral sliding groove 23 form a sliding plug-in lock fit. One end of the battery upper cover plate 2 is movably articulated to the frame 5, and the battery upper cover plate 2 is flipped over and covered above the battery locking mechanism assembly. The other end of the battery upper cover plate 2 is provided with an oblique extension, and the upper end surface of the extension is provided with a limiting groove 28 that forms a limiting fit with the lower end of the seat cushion 1.

[0036] Fig.12 As shown, the elastic hook 10 is an L-shaped hook structure, and the elastic hook 10 includes a connecting portion and a horizontal extension portion that are connected to each other. When the seat cushion 1 presses the U-shaped plate portion 22 and slides to one side, the transverse elastic rod 20 is bent by force, and the U-shaped plate portion 22 fits the inner wall of the bottom slot 24. When the seat cushion 1 releases the pressing force of the U-shaped plate portion 22, the transverse elastic rod 20 resets and applies an elastic force to the U-shaped plate portion 22 to make it fit the upper surface of the horizontal extension portion of the elastic hook 10. This effect can again utilize the elastic force of the transverse elastic rod 20 to facilitate the sliding insertion of the elastic hook 10, and can also realize the sliding locking of the elastic hook 10 and the lateral sliding slot 23 through the transverse elastic rod 20 to prevent the elastic hook 10 from sliding relative to the lateral sliding slot 23 during driving.

[0037] In actual use, the present application can not only lock the power battery 3 through the seat cushion 1 to prevent the power battery 3 from shaking, but also facilitate the removal of the power battery 3 when it is necessary to remove the power battery 3 because there is no driver applying gravity on the seat cushion 1.

[0038] Obviously, the above embodiments of the present invention are merely examples for illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to exhaust all implementation methods here. However, these obvious changes or modifications derived from the essential spirit of the present invention still fall within the protection scope of the present invention.
