Description

Technical Field

[0001] This utility model relates to the field of energy storage technology, and in particular to a locking mechanism and a shared energy storage device. Background Technology

[0002] The shared energy storage device consists of multiple energy storage units and a charging base. The charging base can charge multiple energy storage units. In order to prevent the energy storage units from being lost, the energy storage units need to be locked. In related technologies, the locking structure of the energy storage units is set one-to-one, which is relatively complex. When multiple energy storage units need to be taken out at once, they need to be unlocked one by one, which is also relatively complicated.

[0003] Therefore, there is an urgent need to propose a locking mechanism and a shared energy storage device that can simultaneously lock or unlock multiple energy storage units. Utility Model Content

[0012] In some more specific embodiments, a first stop ring is provided on the inner sidewall of the first perforation, and a second stop ring is provided on the first locking member, wherein the first stop ring abuts against the second stop ring;

[0013] The locking assembly further includes an anti-disengagement component, which is sleeved on the base and has a third anti-abutment protrusion that abuts against the end of the first locking member where the driving part is located, wherein the second anti-abutment protrusion and the third anti-abutment protrusion are used to restrict the sliding of the first locking member relative to the base.

[0018] The beneficial effects of the locking mechanism of this utility model are as follows: In actual operation, when the key is engaged with the locking component and rotated in the locking direction, the first locking member rotates, and the second locking member slides relative to the first locking member. The second locking member then pushes the positioning member to move, causing multiple positioning parts on the positioning member to engage with multiple energy storage units one-to-one, thus locking the energy storage units. At this time, the energy storage units cannot be pulled out along their height direction. When the key is engaged with the locking component and rotated in the unlocking direction, the first locking member rotates in the opposite direction, and the second locking member moves away from the positioning member. The positioning member moves under the action of the elastic member, causing multiple positioning parts on the positioning member to disengage from the positioning grooves of the energy storage units, thus releasing the energy storage units. At this time, the energy storage units can be pulled out along their height direction. Therefore, by using a positioning member with multiple positioning parts and a locking component and elastic member that cooperate with the positioning member, multiple energy storage units can be unlocked or locked simultaneously with a single key, making it convenient for users to remove or put back multiple energy storage units at once, thus improving user satisfaction.

[0019] The beneficial effects of this utility model's shared energy storage device are as follows: Due to the locking mechanism described above, the shared energy storage device can unlock or lock multiple energy storage units simultaneously with a single key, making it convenient for users to take out or put back multiple energy storage units at once, thus improving user satisfaction.

[0049] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0050] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0051] In the description of this embodiment, the terms "upper," "lower," "left," "right," "front," and "rear," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0052] This utility model discloses a locking mechanism 100, see reference. Figures 1-5 , Figure 9 and Figure 10As shown, the locking mechanism 100 is used to lock multiple energy storage units 300 within the base 200. The locking mechanism 100 includes a positioning member 110, a locking component 120, and an elastic member 130. The positioning member 110 is movably installed within the base 200 and has multiple positioning parts 111. The positioning parts 111 can cooperate with the positioning grooves 310 on the energy storage units 300. The locking component 120 passes through the base 200 and includes a base 123 and a first locking member 121 and a second locking member 122 disposed on the base 123. The first locking member 121 is rotatably disposed along the axial direction of the base 123, and the second locking member 122 is slidably disposed along the axial direction of the base 123. One end of the first locking member 121 is provided with a driving part 1211, and the end of the second locking member 122 abuts against the positioning member 110. The first locking member 121 can rotate relative to the second locking member 122. One of the first locking member 121 and the second locking member 122 is provided with an abutting part 1225. The abutting part 1225 is axially arranged around the base 123 and its height gradually increases along the axial direction of the base 123. The other of the first locking member 121 and the second locking member 122 is provided with a protrusion 1212 along the axial direction of the base 123. The abutting part 1225 abuts against the protrusion 1212. The first locking member 121 rotates to drive the second locking member 122 to slide to push the positioning member 110 to lock multiple energy storage units 300. The elastic member 130 is connected between the positioning member 110 and the base 200. The elastic member 130 provides the elastic force to drive the positioning part 111 to disengage from the positioning groove 310.

[0053] It is understandable that, since the first locking member 121 is rotatably disposed along the axial direction of the base 123 and the second locking member 122 is slidably disposed along the axial direction of the base 123, and during the rotation of the first locking member 121, the protrusion 1212 can rotate relative to the abutment 1225. Since the abutment 1225 is axially disposed around the base 123 and its height gradually increases along the axial direction of the base 123, the first locking member 121 can stably push the second locking member 122 to slide along the axis of the base 123 during the rotation of the first locking member 121. Therefore, in actual operation, when the key 400 is engaged with the locking assembly 120 and the key 400 is turned in the locking direction, the first locking member 121 rotates, and the second locking member 122 slides relative to the first locking member 121. The second locking member 122 can then push the positioning member 110 to move, so that the multiple positioning parts 111 on the positioning member 110 are inserted into the multiple energy storage units 300 one by one to lock the energy storage units 300. At this time, the energy storage unit 300 cannot be pulled out along its height direction. After the key 400 is engaged with the locking assembly 120 and the key is turned in the unlocking direction... When the key 400 is turned in the unlocking direction, the first locking member 121 rotates in the opposite direction, and the second locking member 122 moves away from the positioning member 110. At this time, the second locking member 122 stops pushing the positioning member 110 and disengages from it. The positioning member 110 can then move under the action of the elastic member 130, causing the multiple positioning parts 111 on the positioning member 110 to disengage from the positioning groove 310 of the energy storage unit 300, thereby releasing the energy storage unit 300. The energy storage unit 300 can then be pulled out along its height. Thus, by using the positioning member 110 with multiple positioning parts 111 and the locking assembly 120 and elastic member 130 that cooperate with the positioning member 110, multiple energy storage units 300 can be unlocked or locked simultaneously with a single key 400, making it convenient for users to remove or put back multiple energy storage units 300 at once, thus improving user satisfaction.

[0054] It should be noted that in this embodiment, the unlocking direction is counterclockwise and the locking direction is clockwise. Of course, in an alternative embodiment of this invention, the unlocking direction can be clockwise and the locking direction counterclockwise.

[0055] In this embodiment, the elastic element 130 can be a compression spring, with one end abutting against the positioning element 110 and the other end abutting against the base 200. When the locking assembly 120 stops pushing the positioning element 110, the compression spring provides a spring force to the positioning element 110 away from the positioning groove 310. In other embodiments of this invention, the elastic element 130 can also be a tension spring, with one end fixed to the positioning element 110 and the other end fixed to the base 200. When the locking assembly 120 stops pushing the positioning element 110, the tension spring provides a pulling force to the positioning element 110 away from the positioning groove 310. Furthermore, in this embodiment, the first locking element 121 and the second locking element 122 share an axial space, which helps to reduce the overall size of the locking assembly 120, allowing for a thinner wall of the base 200 and a reduction in the volume of the shared energy storage device.

[0056] refer to Figures 4-7 As shown, the drive unit 1211 includes an unlocking protrusion 12112 and an unlocking groove 12111 surrounding the unlocking protrusion 12112. The unlocking protrusion 12112 is provided with an unlocking slot 12113. It can be understood that during actual operation, the key 400 is inserted into the unlocking groove 12111, and the mating protrusion on the key 400 engages with the unlocking protrusion 12112 and the unlocking slot 12113, which can improve the connection stability between the key 400 and the drive unit 1211, thereby ensuring that the user can stably turn the key 400 to unlock or lock the energy storage unit 300.

[0057] refer to Figures 8-11As shown, the first locking member 121 has a protrusion 1212, and the second locking member 122 has a groove 1221. The bottom of the groove 1221 has an abutment 1225. The protrusion 1212 can be inserted into the groove 1221 and abut against the abutment 1225. It can be understood that in actual operation, when the key 400 engages with the first locking member 121 and drives the first locking member 121 to rotate in the locking direction, the protrusion 1212 gradually rotates out of the groove 1221. Since the bottom of the groove 1221 has an abutment 1225, the protrusion 1212 gradually squeezes the abutment 1225 during the process of rotating out of the groove 1221. At this time, the second locking member 122 can move along its axial direction under the drive of the protrusion 1212, thereby causing the second locking member 122 to drive the positioning member 110 to move so as to insert the positioning part 111 into the energy storage unit 300. Conversely, when the key 400 engages with the first locking member 121 and drives the first locking member 121 to rotate in the unlocking direction, the protrusion 1212 gradually rotates into the groove 1221. During the process of the protrusion 1212 rotating into the groove 1221, it gradually disengages from the abutment 1225 inside the groove 1221. At this time, the second locking member 122 stops driving the positioning member 110 and disengages from the positioning member 110. The positioning member 110 can then rebound under the action of the elastic member 130, causing the positioning part 111 to protrude out of the positioning groove 310 of the energy storage unit 300 to unlock the energy storage unit 300.

[0058] Optionally, the abutment portion 1225 is formed as an arc-shaped surface along the circumferential direction of the second locking member 122. Of course, the abutment portion can also be directly formed as an inclined surface. In this embodiment, the abutment portion 1225 is served by the bottom of the groove portion 1221. In other embodiments of this utility model, the abutment portion 1225 can be formed as a protruding structure provided in the groove portion 1221.

[0059] Optional, see reference Figures 10-11As shown, protrusions 1212 are arranged in pairs, and recesses 1221 are arranged in pairs. A contact plane 1222 is provided between two recesses 1221. When the protrusions 1212 abut against the contact plane 1222 and are spaced apart from the recesses 1221, the positioning member 110 locks multiple energy storage units 300. It is understandable that by setting two protrusions 1212, the stability of driving the second locking member 122 during the rotation of the first locking member 121 can be improved. Setting the contact plane 1222 can ensure that when the energy storage unit 300 is locked, the elastic member 130 is pressed down. The reaction force of the elastic member 130 is transmitted through the positioning member 110 to the protrusions 1212 and the contact plane 1222, thereby forming a force. This force can prevent the second locking member 122 from relative displacement with the first locking member 121, thus ensuring effective locking with the energy storage unit 300.

[0060] In an alternative embodiment of this invention, the first locking member 121 and the second locking member 122 may be connected by a thread. Due to the presence of the base 123, the first locking member 121 can also stably drive the second locking member 122 to move.

[0061] Optional, see reference Figure 7 As shown, the base 123 is provided with a first anti-detachment protrusion 1238, and the second locking member 122 is provided with a second anti-detachment protrusion 1224. The second anti-detachment protrusion 1224 can abut against the first anti-detachment protrusion 1238 to prevent the second locking member 122 from detaching from the base 123. It can be understood that during the locking process of the energy storage unit 300, since the second locking member 122 gradually extends out of the first through hole 1231, if the rotation angle of the first locking member 121 is too large, it will cause the second locking member 122 to detach from the base 123, thereby causing the locking assembly 120 to fail. In this embodiment, by providing a first anti-detachment protrusion 1238 on the base 123 and a second anti-detachment protrusion 1224 on the second locking member 122, during the locking of the energy storage unit 300, when the second locking member 122 moves to the position where the second anti-detachment protrusion 1224 stops against the first anti-detachment protrusion 1238, it can no longer move forward. At this time, the first locking member 121 can no longer rotate. In this way, the movement of the second locking member 122 can be controlled within a specified range, ensuring that the locking assembly 120 can work stably.

[0062] Optional, see reference Figures 10-11As shown, the base 123 has a first through hole 1231, through which both the first locking member 121 and the second locking member 122 pass. The second locking member 122 has a first limiting protrusion 1223 extending axially along the first through hole 1231, and the base 123 has a first limiting groove 1232 that mates with the first limiting protrusion 1223. In actual operation, when the first locking member 121 rotates to drive the second locking member 122, the first limiting protrusion 1223, which mates within the first limiting groove 1232, restricts the rotation of the second locking member 122. This ensures that the second locking member 122 can only move along the axial direction of the first through hole 1231, thereby ensuring that the second locking member 122 can stably drive the positioning member 110.

[0063] Alternatively, there may be two first limiting protrusions 1223, which are symmetrically distributed about the center of the cross section of the first through hole 1231, thereby further enhancing the limiting effect on the second locking member 122.

[0064] Optionally, the second locking member 122 is provided with first limiting grooves 1232 on both sides of the first limiting protrusion 1223, and the base 123 is provided with two first limiting grooves 1232 and a first limiting protrusion 1223 located between the two first limiting grooves 1232. It is understood that the provision of first limiting protrusions 1223 and first limiting grooves 1232 on both the second locking member 122 and the base 123 can, on the one hand, further enhance the limiting effect on the second locking member 122, and on the other hand, reduce the mating dimensions of the second locking member 122 and the base 123, thus helping to reduce manufacturing costs. Of course, in alternative embodiments of this invention, the second locking member 122 is provided with only first limiting grooves 1232, and the base 123 is provided with only first limiting protrusions 1223. The distribution of the first limiting protrusions 1223 and the first limiting grooves 1232 can be selected from any of the above methods according to actual needs.

[0065] Optional, see reference Figure 4 , Figure 5 and Figure 7 As shown, a first stop ring 1235 is provided on the inner wall of the first through hole 1231, and a second stop ring 1213 is provided on the first locking member 121. The first stop ring 1235 abuts against the second stop ring 1213. It can be understood that in actual operation, the first locking member 121 can only rotate to stably drive the second locking member 122 to move axially along the mounting hole 221 to drive the positioning member 110 to move. In this embodiment, by providing a first stop ring 1235 on the inner wall of the first through hole 1231 and a second stop ring 1213 on the first locking member 121...

[0066] Optional, see reference Figure 4 , Figure 5 and Figure 7 As shown, the locking assembly 120 also includes an anti-detachment member 125, which is sleeved on the base 123 and has a third abutment protrusion 1251 that abuts against the end of the first locking member 121 where the driving part 1211 is located. The second abutment protrusion 1213 and the third abutment protrusion 1251 are used to limit the sliding of the first locking member 121 relative to the base 123. It can be understood that by providing the anti-detachment member 125, the connection stability between the base 123 and the mounting hole 221 can be improved. Furthermore, the third abutment protrusion 1251 on the anti-detachment member 125 can restrict the first locking member 121, preventing it from detaching from the base 123, thereby ensuring that the locking assembly 120 can stably lock and unlock the energy storage unit 300.

[0067] Further optional, see reference Figures 12-13 As shown, the second stop ring 1213 is provided with a third limiting groove 1214, which is an arc-shaped groove. The first stop ring 1235 is provided with a third limiting protrusion 1236 that cooperates with the third limiting groove 1214. When the third limiting protrusion 1236 rotates relative to the arc-shaped groove, it can limit the rotation angle of the first locking member 121 relative to the base 123. It can be understood that when the user drives the first locking member 121 to rotate using the key 400, the third limiting protrusion 1236 rotates within the arc-shaped groove. The rotation angle of the key 400 during locking and unlocking can be controlled by setting the central angle of the arc-shaped groove. When the third limiting protrusion 1236 abuts against the sidewalls at both ends of the arc-shaped groove along its circumference, the key 400 stops rotating. This can avoid the problem of the locking component 120 failing due to excessive rotation of the first locking member 121.

[0068] Further optional, such as Figure 20 As shown, the base 200 can also be provided with a locking mark 224 and an unlocking mark 225, making the user very clear about the boundaries of use and improving the user experience. Of course, it should be noted that in an alternative embodiment of this utility model, the first stop ring 1235 is provided with a third limiting groove 1214, and the second stop ring 1213 is provided with a third limiting protrusion 1236.

[0069] Optional, see reference Figure 7As shown, the locking assembly 120 also includes a locking member 124, which is mounted on the inner wall of the base 200. The locking member 124 has a limiting rib 1241, and the base 123 has a limiting slot 1237 that mates with the limiting rib 1241. It is understood that the second limiting protrusion 1233 and the first anti-rotation plane 1234 can only prevent the base 123 from rotating relative to the mounting hole 221. The added locking member 124 can restrict the movement of the base 123 along the axis of the mounting hole 221, thereby ensuring that the base 123 is fixed within the mounting hole 221 and preventing the locking assembly 120 from failing due to the movement of the base 123. Further optionally, the locking member 124 has two limiting ribs 1241, and the base 123 has two symmetrically arranged limiting slots 1237, thereby improving the installation stability of the base 123. It should be noted that, in an alternative embodiment of this utility model, a limiting slot 1237 is provided on the locking member 124, and a limiting rib 1241 is provided on the base 123.

[0070] Optional, see reference Figure 14 As shown, one end of the positioning part 111 is formed into a cone shape with a gradually decreasing cross-sectional area. Therefore, during the locking process, the positioning part 111 can be smoothly inserted into the positioning slot 310 of the energy storage unit 300, thereby locking the energy storage unit 300.

[0071] Optional, see reference Figures 16-17 As shown, the base 200 has a mounting hole 221, and the base 123 passes through the mounting hole 221. The base 123 has a second limiting protrusion 1233 extending axially along the mounting hole 221, and the inner wall of the mounting hole 221 has a second limiting groove 223 that mates with the second limiting protrusion 1233. It can be understood that the axial movement of the mounting hole 221 is restricted by the engagement of the second limiting protrusion 1233 and the second limiting groove 223, thus ensuring the stability of the base 123.

[0072] Optional, see reference Figures 16-17As shown, the outer wall of the base 123 is provided with a first anti-rotation plane 1234, and the inner wall of the mounting hole 221 is formed with a second anti-rotation plane 222 corresponding to the first anti-rotation plane 1234. It is understood that in actual operation, the base 123 needs to remain fixed relative to the mounting hole 221 to ensure that the second locking member 122 can move stably along the axial direction of the mounting hole 221. By setting the cooperation of the first anti-rotation plane 1234 and the second anti-rotation plane 222, the rotation of the base 123 relative to the mounting hole 221 is restricted, thereby ensuring the stability of the base 123. Optionally, there are two first anti-rotation planes 1234, symmetrically distributed about the geometric center of the base 123. Correspondingly, there are also two second anti-rotation planes 222, which enhances the restraining effect on the base 123 and prevents the base 123 from rotating relative to the mounting hole 221.

[0073] It should be noted that in this embodiment, the base 123 is provided with both a second limiting protrusion 1233 and a first anti-rotation plane 1234. In other embodiments of this utility model, the base 123 may be provided with one of them.

[0074] This utility model also discloses a shared energy storage device, see reference. Figure 1 As shown, the shared energy storage device includes a base 200, multiple energy storage units 300, and the aforementioned locking mechanism 100. The base 200 has a receiving groove 211 and a mounting hole 221 communicating with the receiving groove 211. The multiple energy storage units 300 are installed in the receiving groove 211. The locking component 120 of the locking mechanism 100 passes through the mounting hole 221, and the positioning component 110 of the locking mechanism 100 is movably installed in the receiving groove 211. Due to the aforementioned locking mechanism 100, the shared energy storage device can simultaneously unlock or lock multiple energy storage units 300 using a single key 400, making it convenient for users to remove or put back multiple energy storage units 300 at once, thus improving user satisfaction.

[0075] Optional, see reference Figure 2As shown, the base 200 includes a lower shell 220 and an upper shell 210. A mounting hole 221 is provided on the lower shell 220, and the upper shell 210 has multiple spaced-apart receiving slots 211, each for accommodating one energy storage unit 300. A positioning member 110 is installed between the side wall of the upper shell 210 and the side wall of the lower shell 220. The upper shell 210 also has a second through hole 212 communicating with the receiving slots 211, and the positioning part 111 of the positioning member 110 engages with the second through hole 212. It is understood that installing the positioning member 110 between the side walls of the upper shell 210 and the lower shell 220 improves the installation stability of the positioning member 110 and allows it to be hidden inside the base 200, preventing the energy storage unit 300 from unlocking due to exposed force on the positioning member 110. Multiple receiving slots 211 are provided on the upper shell 210, each receiving slot 211 is used to accommodate one energy storage unit 300. Compared with the structure of the receiving slot 211 being a long slot, the energy storage unit 300 has better stability and avoids the phenomenon of the energy storage unit 300 being tilted.

[0076] Optional, see reference Figure 15 and Figure 19 As shown, the upper shell 210 has a guide post 213 on its side wall, and the positioning member 110 has a guide portion 112. The guide portion 112 is sleeved on the guide post 213, and the elastic member 130 is installed on the guide post 213. One end of the elastic member 130 abuts against the guide portion 112, and the other end abuts against the side wall of the upper shell 210. It can be understood that, with the guide portion 112 sleeved on the guide post 213, during the movement of the positioning member 110, due to the guiding effect of the guide post 213 on the guide portion 112, the positioning member 110 can only move axially along the mounting hole 221, preventing the positioning member 110 from becoming misaligned during movement and thus avoiding jamming. Optionally, there can be multiple guide posts 213, and correspondingly multiple elastic members 130. This further prevents the positioning member 110 from becoming misaligned, and during the unlocking process, the multiple elastic members 130 can ensure that the positioning member 110 rebounds stably, thereby causing the positioning part 111 to disengage from the positioning slot 310 of the energy storage unit 300.

[0077] Optional, see reference Figure 15 and Figure 19As shown, a fixing post 214 is provided on the side wall of the upper shell 210, and a fixing hole 113 is provided on the positioning member 110 to cooperate with the fixing post 214. The fixing member 500 can pass through the fixing hole 113 and connect with the fixing post 214, and the fixing member 500 can prevent the fixing post 214 from coming out of the fixing hole 113. It can be understood that the cooperation between the fixing post 214 and the fixing hole 113 can play an auxiliary guiding role, thereby further avoiding the phenomenon of the positioning member 110 being misaligned and jammed during movement. The fixing member 500 limits the stroke of the positioning member 110, preventing the positioning member 110 from coming out of the fixing post 214, thereby better preventing the phenomenon of the locking component 120 from failing due to the misalignment of the positioning member 110. Further optionally, there are multiple fixing posts 214 and fixing holes 113, thereby improving the guiding and anti-disengagement function of the positioning member 110.

[0078] Optional, see reference Figure 15 and Figure 19 As shown, the upper shell 210 also has a first limiting portion 215 and a second limiting portion 216 spaced apart along the height direction of the energy storage unit 300 on its side wall. The first limiting portion 215 and the second limiting portion 216 respectively abut against the two side walls of the positioning member 110 spaced apart along the height direction of the energy storage unit 300. It can be understood that the first limiting portion 215 and the second limiting portion 216 abut against the two side walls of the positioning member 110 spaced apart along the height direction of the energy storage unit 300, which can completely restrict the vertical movement of the positioning member 110, thereby avoiding the phenomenon of the positioning member 110 being misaligned and jammed. Further optionally, the first limiting portion 215 is a protrusion formed on the upper shell 210 and extending downward, and the second limiting portion 216 includes two spaced L-shaped protrusions.

[0079] Optional, see reference Figure 15 As shown, the positioning member 110 is provided with multiple reinforcing ribs 114. This helps to improve the strength of the positioning member 110 and prevents the positioning member 110 from bending.

[0081] First, by controlling the key 400, the locking and unlocking of multiple energy storage units 300 can be achieved, which is highly flexible and versatile;
