[0030] The first aspect of the embodiment of the present application provides a mounting mechanism. Figures 1 to 8 The structure and working principle of the installation mechanism are described in detail.

[0031] According to the installation mechanism provided in the embodiment of the present application, the installation mechanism is used to install the energy storage mechanism, and the installation mechanism includes a platform and a linkage component.

[0032] In an embodiment, the platform has a bearing surface for bearing the energy storage mechanism. In an embodiment, the linkage assembly includes an abutment member and a first force member connected to each other, the linkage assembly is pivotally connected to the platform, the first force member has a first position protruding relative to the bearing surface, and the first force member also has a second position with a protrusion relative to the bearing surface that is less than the first position.

[0033] In an embodiment, the first force applying member is abuttable by the energy storage mechanism to move from the first position to the second position and cause the abutment member to abut the energy storage mechanism.

[0034] Thus, according to the installation mechanism provided in the embodiment of the present application, when the energy storage mechanism is placed on the bearing surface of the platform, the energy storage mechanism abuts against the first force member, causing the first force member to move from the first position to the second position, thereby causing the abutment member to be linked with the first force member and abut against the outside of the energy storage mechanism as the first force member moves, thereby limiting the energy storage mechanism. Thus, according to the installation mechanism provided in the embodiment of the present application, when the energy storage mechanism is placed on the platform, the energy storage mechanism is simultaneously limited, thereby achieving installation of the energy storage mechanism on the platform.

[0035] According to the installation mechanism provided in the embodiment of the present application, the linkage assembly may include a pressing component, which may be connected to the first force-applying component, which may be used to be pressed on the outside of the energy storage mechanism, and which may be used to be clamped on the outside of the energy storage mechanism.

[0036] Thus, according to the installation mechanism provided in the embodiment of the present application, the energy storage mechanism is positioned by directly abutting and clamping the pressing member with the energy storage mechanism. In the embodiment, as an example, the pressing member can be clamped on the outside of the installation mechanism, thereby further positioning the energy storage mechanism.

[0037] In an embodiment, one of the pressing member and the energy storage mechanism may have a step, and the other may be stuck at the step. In an embodiment, the energy storage mechanism may be placed on the platform along the vertical direction, so that the step formed on the outer side of the energy storage mechanism makes the lower part of the energy storage mechanism have a smaller cross-sectional area relative to the upper part, so as to avoid the step from being stuck when the energy storage mechanism is lifted from the platform. For the pressing member, the step direction of the pressing member is opposite to the step direction of the aforementioned energy storage mechanism, which can also ensure that the step is still stuck on the energy storage mechanism when the energy storage mechanism is lifted from the platform.

[0038] Furthermore, as an example, the pressing member may be a plate-like structure.

[0039] According to the installation mechanism provided in the embodiment of the present application, the first force applying member may include a first force applying body and a contact member.

[0040] In an embodiment, the first force applying body may have a first end and a second end opposite to each other, and the first end of the first force applying body is connected to the abutment member. In an embodiment, the contact member has a curved surface for contacting the energy storage mechanism, and the contact member is connected to the second end of the first force applying body.

[0041] In an embodiment, the curved surface of the contact member can avoid scratching the energy storage mechanism when in contact with the energy storage mechanism, and also facilitates the energy storage mechanism to fine-tune its position in a sliding manner relative to the contact member. In an embodiment, as an example, the curved surface of the contact member can be, for example, an outer cylindrical surface or a spherical surface, and therefore, the contact member can be, for example, cylindrical or spherical.

[0042] According to the installation mechanism provided in the embodiment of the present application, the linkage assembly may further include a reset member, which may connect the linkage assembly and the platform so that the reset member always has a tendency to cause the first force-applying member to be located in the first position.

[0043] Therefore, according to the installation mechanism provided in the embodiment of the present application, the reset component enables the first force member to be reset to the first position due to the reduction in the abutment degree of the energy storage mechanism on the first force member when the energy storage mechanism begins to be removed, thereby causing the abutment member to synchronously move away from the storage mechanism to release the energy storage mechanism.

[0044] According to the installation mechanism provided in the embodiment of the present application, the energy storage mechanism has a first direction in its extension direction, and at least two linkage assemblies are provided, wherein the two linkage assemblies are arranged relative to each other at least in the first direction.

[0045] In an embodiment, as an example, four linkage assemblies may be provided, and the four linkage assemblies are opposite to each other in the first direction. In an embodiment, the pressing components of the linkage assemblies on the same side of the energy storage mechanism may be connected as a whole, that is, as the same plate. Here, the first direction may be, for example, the length direction of the energy storage mechanism, and the subsequent second direction may be, for example, the width direction of the energy storage mechanism.

[0046] According to the installation mechanism provided in the embodiment of the present application, the energy storage mechanism has a second direction in its extension direction, and the energy storage mechanism also includes a first clamping member and a second clamping member opposite to each other in the second direction, and the first clamping member and the second clamping member can be close to each other to clamp the energy storage mechanism. Here, the second direction is as described above, which is the width direction of the energy storage mechanism perpendicular to the first direction.

[0047] According to the installation mechanism provided in the embodiment of the present application, the installation mechanism may further include a second force-applying member, which can be moved close to and away from the platform, and the second force-applying member can be pressed onto the energy storage mechanism from a side opposite to the bearing surface.

[0048] According to the installation mechanism provided in the embodiment of the present application, the installation mechanism may further include a connecting member, which may connect the second force member and the platform, and the second force member may slide along the connecting member to approach and move away from the platform. In the embodiment, the second force member may be pressed on the top of the energy storage mechanism along the vertical direction, so as to achieve comprehensive positioning of the energy storage mechanism in the directions of the three coordinates. When the energy storage mechanism needs to be removed, the positioning of the second force member is first released, and then the energy storage mechanism is lifted.

[0049] According to the installation mechanism provided in the embodiment of the present application, the connecting member is configured to provide a plurality of positioning positions for the second force-applying member, and the second force-applying member is positioned relative to the connecting member at each positioning position. Thus, some of the aforementioned plurality of positioning positions can be used as positions for releasing the energy storage mechanism, and one of the remaining positioning positions can be used as a force-applying position abutting against the upper side of the energy storage mechanism. In addition, according to energy storage mechanisms of different heights, one positioning position can be provided as a force-applying position in each of the aforementioned plurality of positioning positions, and the positioning position above the positioning position is the position for releasing the energy storage mechanism.

[0050] Based on the above description, an implementation example of the mounting mechanism will be described in detail below.

[0051] In the embodiment, the supporting plate 1 is used as the above platform. The energy storage battery body 2 (i.e., the energy storage mechanism) is placed on the top surface of the supporting plate 1, and a right-angle baffle 3 can be fixedly connected to the top surface of the supporting plate 1 by bolts. The right-angle baffle 3 is in contact with the surface of the energy storage battery body 2 and is also used to provide positioning for the energy storage battery body 2.

[0052] In the embodiment, the surface of the carrier plate 1 may be provided with a mounting groove 4 and a receiving groove 5, the inner wall of the mounting groove 4 is rotatably connected with a rotating shaft 6, and a coil spring 8 (i.e., a reset member) is installed between the rotating shaft 6 and the inner wall of the mounting groove 4. In the embodiment, a bent rod 7 (i.e., an abutment member) is fixedly connected to the surface of the rotating shaft 6, a side pressure plate 9 (i.e., the pressure member includes the side pressure plate 9) is fixedly connected to the end of the bent rod 7, and a pressing pad 10 (i.e., the pressing member also includes the pressing pad 10, such as the pressing pad 10 made of elastic materials such as rubber) is fixedly connected to the surface of the side pressure plate 9.

[0053] As an example, different from the above step example, both sides of the energy storage battery body 2 may be provided with side pressure grooves 18, and the compression pad 10 is movably engaged with the inner wall of the side pressure groove 18. In the embodiment, the other end of the bent rod 7 may be fixedly connected with a resisting column 11 (i.e., the above contact member), and the resisting column 11 is in contact with the bottom surface of the energy storage battery body 2.

[0054] Under normal conditions, the lower end of the bent rod 7 extends out from the inside of the accommodating groove 5, and the position of the abutment column 11 is higher than the supporting plate 1. When the energy storage battery body 2 is placed on the top surface of the supporting plate 1, the abutment column 11 will be squeezed, thereby pushing the bent rod 7 to rotate. The upper end of the bent rod 7 will push the side pressure plate 9 to move, so that the side pressure plate 9 is stuck into the inner wall of the side pressure groove 18, clamping and fixing the two sides of the energy storage battery body 2.

[0055] When taking the energy storage battery body 2, just pull the energy storage battery body 2 upwards. Under the elastic force of the coil spring 8, the rotating shaft 6 will be reset, thereby driving the bending rod 7 to rotate, so that the side pressure plate 9 is separated from the inner wall of the side pressure groove 18, thereby automatically releasing the limit. This design makes the installation and removal of the energy storage battery body 2 simple and quick, greatly improving the convenience of use, and is especially suitable for scenes that require frequent movement and installation of energy storage batteries, such as outdoor camping. When the energy storage battery body 2 is located on the top surface of the supporting plate 1, the right-angle baffle 3 can assist in limiting the energy storage battery body 2 on the front and rear sides, and play a positioning role, so as to facilitate the determination of the placement position of the energy storage battery body 2.

[0056] In the embodiment, a slide groove 12 may also be provided on the supporting plate 1, and a double-headed screw 19 is rotatably connected to the inner wall of the slide groove 12, and a knob 13 is fixedly connected to the front end of the double-headed screw 19, and two mounting vertical rods 14 (i.e., the first clamping member and the second clamping member) are threadedly connected to the surface of the double-headed screw 19, and a sliding sleeve 15 is movably sleeved on the surface of the mounting vertical rod 14, and connecting rods 16 are fixedly connected to the left and right sides of the sliding sleeve 15, and an upper clamping block 17 (i.e., the second force-applying member) is fixedly connected to the end of the connecting rod 16.

[0057] In the embodiment, an upper card slot 21 is provided on the top surface of the energy storage battery body 2, and the inner wall of the upper card slot 21 is movably engaged with the upper card block 17. It should be noted that the user can turn the knob 13 to drive the double-headed screw 19 to rotate, so that the two mounting vertical rods 14 can slide along the inner wall of the slide slot 12 and approach each other, drive the sliding sleeve 15 and the connecting rod 16 to approach the energy storage battery body 2, so that the upper card block 17 can reach the top of the upper card slot 21, slide the sliding sleeve 15 downward, and drive the connecting rod 16 and the upper card block 17 to descend, so that the upper card block 17 is stuck in the inner wall of the upper card slot 21, and the energy storage battery body 2 can be limited and fixed. When it is necessary to go out to take the energy storage battery body 2, the reverse operation can be performed to quickly take out the energy storage battery body 2, thereby realizing reliable fixation and rapid disassembly of the top of the energy storage battery body 2, improving the reliability of the device and the accuracy of operation.

[0058] In the embodiment, the inner wall of the mounting vertical rod 14 is slidably connected with the mounting bar 20, the end of the mounting bar 20 is fixedly connected with a pressing block 22, and the pressing block 22 is movably connected to the mounting vertical rod 14, a spring 24 is fixedly connected between the mounting bar 20 and the inner wall of the mounting vertical rod 14, the surface of the mounting bar 20 is fixedly connected with an insertion rod 23, the insertion rod 23 is movably connected to the mounting vertical rod 14, the inner wall of the sliding sleeve 15 is provided with an alignment hole 25, and the inner wall of the alignment hole 25 is movably connected to the end of the insertion rod 23.

[0059] In the embodiment, the user can press the pressing block 22 horizontally, and the pressing block 22 is deformed, and then drives the installation bar 20 and the insertion rod 23 to move horizontally, so that the installation bar 20 moves. At this time, the spring 24 will be stretched, and the installation bar 20 will drive the insertion rod 23 to move, so that it will be separated from the inner wall of the alignment hole 25, and the limiting effect on the sliding sleeve 15 can be released. At this time, the sliding sleeve 15 can be pulled down, so that the upper clamping block 17 can be inserted into the upper clamping groove 21, and then the pressing block 22 is released. Under the elastic force of the spring 24, the installation bar 20 will be pushed to move, so that the insertion rod 23 is reinserted into the inner wall of the alignment hole 25 to fix the sliding sleeve 15. In the embodiment, the matching structure of the installation bar 20, the pressing block 22, the spring 24, the insertion rod 23 and the alignment hole 25 provides a reliable limiting and unlocking function for the movement of the sliding sleeve 15. This design ensures that the upper clamping block 17 can be accurately inserted into or released from the upper clamping slot 21, thereby achieving reliable fixation and rapid disassembly of the top of the energy storage battery body 2, and improving the reliability of the device and the accuracy of operation.

[0060] In the embodiment, the bottom of the carrier plate 1 is fixedly connected to a support frame 26, and the bottom surface of the support frame 26 is fixedly connected to an anti-skid pad 27, and the anti-skid pad 27 is made of rubber. When the energy storage battery body 2 is used indoors, the support frame 26 is used to support and fix the whole body, and the anti-skid pad 27 made of rubber is used to buffer the whole body to avoid the influence of external vibration on the whole body. In the embodiment, the combination of the support frame 26 and the anti-skid pad 27 made of rubber provides a stable support foundation for the energy storage device and plays a good buffering role. This design effectively avoids the influence of external vibration on the energy storage battery body 2, ensures the safety and stability of the energy storage battery body 2 during use, and prolongs the service life of the battery.

[0061] In the embodiment, the number of the insertion rods 23 is two groups, upper and lower. More specifically, when the energy storage battery body 2 is not fixed, the upper insertion rods 23 are inserted into the alignment holes 25, and when the energy storage battery body 2 is fixed, the alignment holes 25 just match the lower insertion rods 23.

[0062] According to the second aspect of the embodiment of the present application, an energy storage device is provided, which includes the above mounting mechanism, which is used to detachably mount the above energy storage mechanism, and also has the above beneficial effects, which will not be repeated here. Here, the energy storage mechanism can be, for example, an energy storage lithium battery pack.

[0063] The above are only preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. All equivalent structural changes made by using the contents of the present application specification and drawings under the innovative concept of the present application, or directly / indirectly applied in other related technical fields are included in the protection scope of the present application.
