In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0035] The present invention discloses a fixing device for an energy storage power supply, referring to Figure 1 As shown, a fixing device of an energy storage power supply (hereinafter referred to as the fixing device for convenience of description) is used to fix the energy storage power supply 10 placed on an external mounting surface. The fixing device includes a first base 100, a second base 300 and a fixing belt 400. The first base 100 is provided with a belt compartment 200. The first base 100 is installed on the external mounting surface, the second base 300 is installed on the external mounting surface and is spaced apart from the first base 100. A fixing portion is provided on the second base 300. The first end of the fixing belt 400 is rolled up in the belt compartment 200, and the second end of the fixing belt 400 is detachably connected to the fixing portion. The fixing belt 400 can stop on the outer wall of the energy storage power supply 10 to fix the energy storage power supply 10. It is understandable that, in the actual working process, after the energy storage power supply 10 is placed on the external installation surface, the first base 100 and the second base 300 can be fixed on both sides of the energy storage power supply 10 according to actual needs, and then the fixed belt 400 in the wound state in the belt compartment 200 is pulled out over the top of the energy storage power supply 10, and the second end of the fixed belt 400 is fixed to the fixed part of the second base 300, so that the fixed belt 400 presents a U-shaped structure with an opening downward, and the energy storage power supply 10 can be fixed on the external installation surface, thereby avoiding the energy storage power supply 10 from shaking during transportation. Since the distance between the second base 300 and the first base 100 can be adjusted according to the size of the energy storage power supply 10, the length of the fixed belt 400 can also be adjusted according to the size of the energy storage power supply 10, so that the fixing device of this embodiment can be applied to energy storage power supplies 10 of different sizes, which is conducive to improving user satisfaction.

[0036] It should be noted that the first base 100 and the second base 300 can be fixed to the external mounting surface by connecting parts such as screws, or by structures such as snaps, and the connection method between the first base 100 and the second base 300 and the external mounting surface can be adjusted according to actual needs.

[0037] Optionally, a day byte 420 is provided on the fixing belt 400. It is understandable that when the fixing device is working normally, the user pulls the fixing belt 400 out of the belt compartment 200, and the day byte 420 on the fixing belt 400 can be used to adjust the length of the fixing belt 400, thereby realizing the function of tightening the energy storage power supply 10.

[0038] refer to Figure 2-Figure 4 As shown, the first base 100 includes a first fixed base 110 and a rotating shaft 120, the first fixed base 110 is used to be connected to the external mounting surface, and the belt compartment 200 is installed on the first fixed base 110, the first fixed base 110 is provided with an adjustment slot 1121, the rotating shaft 120 is rotatably arranged in the adjustment slot 1121, and the rotating shaft 120 is arranged in the belt compartment 200, and the first end of the fixed belt 400 is wound around the rotating shaft 120. It can be understood that in the actual working process, when the energy storage power supply 10 needs to be released, it is only necessary to remove the second end of the fixed belt 400 from the fixed part of the second base 300, and then drive the rotating shaft 120 to rotate, and the fixed belt 400 can be easily retracted, thereby facilitating the storage of the fixing device.

[0039] refer to Figure 3 As shown, the first base 100 also includes an elastic member 130, which is installed on the first fixed base 110. The elastic member 130 is used to provide elastic force to the rotating shaft 120 so that the rotating shaft 120 slides relative to the adjustment slot 1121. It can be understood that in the actual working process, when the user wants to implement the action of tightening the energy storage power supply 10, the user first manually extracts the fixing belt 400 from the belt compartment 200 and roughly adjusts the length of the fixing belt 400 through the digit 420 on the fixing belt 400. When the second end of the fixed belt 400 to be extracted approaches the second base 300, the rough adjustment action is stopped, and the elastic sliding range of the rotating shaft 120 in the adjustment slot 1121 is used to deform the elastic member 130 to achieve the final tightening and binding link, and then the second end of the fixing belt 400 is fixed to the fixed part of the second base 300 to complete the binding. When the second end of the fixing belt 400 is separated from the fixing portion of the second base 300, the elastic member 130 can drive the rotating shaft 120 to move in the adjusting slot 1121 in the process of restoring the original length, so that the fixing belt 400 is loosened, thereby facilitating the winding. Therefore, by adding the elastic member 130, on the one hand, the fixing belt 400 can be tightened and the fixing belt 400 can better fix the energy storage power supply 10 on the external installation surface, which is conducive to improving the installation stability of the energy storage power supply 10, and on the other hand, it is convenient to wind up the fixing belt 400, thereby facilitating the storage of the fixing device.

[0040] Optional, such as Figure 3 and Figure 5As shown, the first fixed seat 110 includes a base plate 111 and two fixed plates 112, the two fixed plates 112 are arranged on the base plate 111 at intervals, and the base plate 111 is provided with a first fixing hole, and the user can fix the first fixed seat 110 on the external mounting surface by a first fixing member inserted through the first fixing hole. The first fixing member can be a bolt or a fixing pin, which can be selected according to actual needs. Both fixed plates 112 are provided with an adjustment groove 1121, and a mounting shaft 140 and a stop shaft 150 are provided between the two fixed plates 112. The elastic member 130 is a torsion spring, which is sleeved on the mounting shaft 140, and one elastic arm of the torsion spring stops at the stop shaft 150, and the other elastic arm stops at the rotating shaft 120. It can be understood that the rotating shaft 120 is inserted into the adjustment groove 1121 of the two fixed plates 112, which can ensure that the rotating shaft 120 slides in the adjustment groove 1121 and rotates around its own axis. The elastic member 130 is configured as a torsion spring, and the two elastic arms of the torsion spring are respectively abutted on the rotating shaft 120 and the abutting shaft 150. When tightening the fixing belt 400, the rotating shaft 120 is driven to slide in the adjusting groove 1121, thereby driving the elastic arm of the torsion spring abutting on the rotating shaft 120 to move, so that the torsion spring is twisted to achieve the tightening of the fixing belt 400. When the second end of the fixing belt 400 is separated from the fixing part, the torsion spring can drive the rotating shaft 120 to move when it returns to its original state, thereby achieving the winding of the fixing belt 400.

[0041] refer to Figure 4 As shown, there are multiple first bases 100, and multiple first bases 100 share a rotating shaft 120, and an operating wheel 121 is provided on the rotating shaft 120. It can be understood that there are multiple first bases 100, and the corresponding second bases 300 and fixing belts 400 are also multiple. Compressing the energy storage power supply 10 with multiple fixing belts 400 can improve the installation stability of the energy storage power supply 10. Multiple first bases 100 share a rotating shaft 120. During the storage process, only the rotating shaft 120 needs to be rotated to achieve the simultaneous rewinding of multiple fixing belts 400, which is convenient for the storage of the fixing device. An operating wheel 121 is provided on the rotating shaft 120, which is convenient for the user to drive the rotating shaft 120 to rotate, thereby further facilitating the rewinding of the fixing belt 400.

[0042] Of course, in an alternative embodiment, there may be multiple rotating shafts 120, and each rotating shaft 120 is arranged corresponding to a first base 100. Although this will increase the time for winding up multiple fixing belts 400, in actual working process, the number of first bases 100 can be increased or reduced according to the size of the energy storage power source 10, which is further convenient for use.

[0043] refer to Figure 6As shown, the second base 300 includes a second fixing seat 310 and a locking seat 320. The second fixing seat 310 is used to cooperate with the external mounting surface. The second fixing seat 310 is provided with a second fixing hole. The user can fix the second fixing seat 310 on the external mounting surface by a second fixing member inserted through the second fixing hole. The second fixing member can be a bolt or a fixing pin, which can be selected according to actual needs. The locking seat 320 is adjustably mounted on the second fixing seat 310 along the length direction of the second fixing seat 310, and the locking seat 320 is provided with a fixing portion for cooperating with the fixing belt 400. It can be understood that since the locking seat 320 cooperating with the second end of the fixing belt 400 is adjustably mounted on the second fixing seat 310 along the extension direction of the second fixing seat 310, the position of the locking seat 320 relative to the second fixing seat 310 can be adjusted according to the size of the energy storage power supply 10 during the actual working process. On the one hand, the fixing belt 400 can better press the energy storage power supply 10, and on the other hand, it can be compatible with energy storage power supplies 10 of more sizes, which is conducive to expanding the scope of application of the fixing device.

[0044] refer to Figure 6 As shown, the second fixed seat 310 is provided with a sliding groove 311 and a locking groove 312, the sliding groove 311 is extended along the length direction of the second fixed seat 310, there are multiple locking grooves 312, and the multiple locking grooves 312 are arranged at intervals along the length direction of the second fixed seat 310, and the locking grooves 312 are connected to the sliding groove 311. The second base 300 also includes a slip ring 330, which is slidably mounted on the sliding groove 311 and connected to the locking seat 320 through an elastic band 500. It can be understood that when it is necessary to adjust the position of the locking seat 320 relative to the second fixed seat 310, it is only necessary to move the driving slip ring 330 downward to stretch the elastic band 500 to make it disengage from the locking groove 312, and then slide the slip ring 330 along the extension direction of the sliding groove 311. When the slip ring 330 slides to the specified position, release the slip ring 330, and the slip ring 330 will be stuck in the specified locking groove 312 under the rebound action of the elastic band 500. This adjustment method is very simple and convenient.

[0045] Optional, reference Figure 7 As shown, the locking seat is provided with a fixing ring 325, and the fixing ring 325 is used to bind the fixing belt 400. Thus, the connection between the locking seat and the fixing belt 400 can be conveniently and firmly achieved.

[0046] It should be supplemented that, in other embodiments of the present invention, the adjustment method of the locking seat relative to the second fixed seat 310 can also be designed as other structures according to actual needs. For example, a positioning column is provided on the locking seat, and a plurality of positioning holes are provided on the second fixed seat 310 and are arranged at intervals along its length direction. When the position of the locking seat needs to be adjusted, it is only necessary to pull the positioning column of the second fixed seat 310 out of one positioning hole and insert it into another positioning hole.

[0047] refer to Figure 7 As shown, the second end of the fixing belt 400 is provided with a buckle 410, and the locking seat 320 includes a shell 321, a locking member 322 and an operating member 323. The shell 321 has an installation cavity, and the installation cavity has an opening for inserting the buckle 410, and the opening constitutes a fixing portion. The locking member 322 is movably installed in the shell 321 and is used to lock the buckle 410. The locking member 322 is movably installed in the shell 321, and one end of the operating member 323 extends into the installation cavity and abuts against the locking member 322. It can be understood that in actual use, after the user pulls the fixing belt 400 out of the belt compartment 200 and adjusts the length, the buckle 410 is directly inserted into the opening. The buckle 410 can cooperate with the locking member 322 during the insertion of the opening, so that the buckle 410 is locked on the locking seat. This plug-in locking method is very simple to operate and has high reliability, which is conducive to fixing the second end of the fixing belt 400 in the locking seat. When the lock needs to be released, the user only needs to drive the operating member 323 to move it, and the operating member 323 can drive the locking member 322 to release the buckle 410. This structure of operating the operating member 323 to release the buckle 410 is very simple to operate, which is conducive to improving user satisfaction.

[0048] Optional, reference Figure 7 As shown, the locking member 322 is a spring sheet, which includes a main body 3221 and a spring tongue 3222. The main body 3221 is a U-shaped structure and is rotatably installed in the installation cavity through a rotating shaft 324. One side of the main body 3221 can contact the operating member 323. The spring tongue 3222 is connected to the main body 3221 and is used to lock the buckle 410. In the actual working process, when the buckle 410 is inserted into the locking seat 320, the end of the buckle 410 will first contact the spring tongue 3222, and the buckle 410 will apply downward pressure to the spring tongue 3222, so that the spring sheet will rotate around the rotating shaft 324. In addition to the curvature of the spring tongue 3222 itself and the overall elastic properties of the spring sheet, the buckle 410 will be smoothly inserted into the locking seat 320 and finally remain locked with the spring tongue 3222. When the outdoor power source needs to be untied, the operating member 323 can be pressed, and the buckle 410 and the spring tongue portion 3222 are suspended, and the buckle 410 is quickly pulled away from the locking seat 320 to complete the untying action. Using a spring sheet as the locking member 322 can lock and release the buckle 410 very conveniently.

[0049] It should be noted that in alternative embodiments of the present invention, the buckle 410 and the locking seat 320 may be locked in other ways, such as the upper end of the housing 321 is open, and a plug hole is provided on the side wall. When the buckle 410 is inserted into the housing 321, the buckle 410 and the locking seat 320 are fixed by inserting a pin into the plug hole. In addition, the detachable connection method between the second end of the fixing belt 400 and the locking seat 320 can also be selected according to actual needs. For example, the fixing portion of the locking seat 320 is formed as a winding shaft, and the second end of the fixing belt 400 is directly wound on the winding shaft, and then fixed on the winding shaft by a pin or a fixing pin.

[0050] Optional, reference Figure 7 As shown, the housing 321 is provided with an operating hole that matches the operating member 323; the operating member 323 includes a pressing portion 3231, a limiting portion 3232 and abutting portion 3233 that are connected in sequence, the abutting portion 3233 is passed through the operating hole and abuts against the main body 3221, and the limiting portion 3232 abuts against the outer wall of the housing 321. It can be understood that the pressing portion 3231 can facilitate the user to press the operating member 323 when unlocking the buckle 410, the limiting portion 3232 can prevent the user from over-pressing the operating member 323 to make it fall into the installation cavity, and the abutting portion 3233 abuts against the main body 3221 to facilitate the separation of the spring tongue portion 3222 from the buckle 410 when unlocking.

[0051] The fixing device disclosed in the present invention realizes the binding and fixing of the energy storage power supply 10 through an adjustable fixing belt 400; the final tensioning action of the fixing belt 400 is realized by a torsion spring arranged on the first base 100, and the position adjustment of the slip ring 330 is realized by arranging a plurality of adjustable locking grooves 312 positions on the second base 300, so as to better be compatible with products of different specifications and sizes and meet the clamping requirements of products of different appearance sizes; the locking and unbinding of the fixing belt 400 and the second base 300 are conveniently realized through the special design of the buckle 410 and the locking seat 320.
