Description

Technical Field

[0001] This utility model relates to the field of new energy storage technology, and more specifically, to an energy storage device and its base structure. Background Technology

[0002] The foot pads at the bottom of the energy storage device provide support, but in special outdoor scenarios, such as uneven ground, this can lead to low stability. Furthermore, the height of the energy storage device is fixed and cannot be adjusted.

[0003] The base structures disclosed in the prior art are generally relatively large and not easy to carry. For energy storage devices with specific foot pad structures, such as energy storage devices with two sets of foot pad structures at the bottom and the two sets of foot pad structures intersecting, there are currently no documents describing the relevant base structure for such energy storage devices. Utility Model Content

[0004] The present invention aims to at least solve the problem of low stability of energy storage devices in special outdoor scenarios in related technologies.

[0005] To this end, the first aspect of this utility model provides a base structure for an energy storage device. The energy storage device includes four foot support structures. The base structure of the energy storage device includes: two base bodies intersecting in their length directions; one base body connecting two foot support structures, and the other base body connecting two other foot support structures; each base body including a mounting groove; two foot support structures extending into the mounting groove from its opening and detachably connected to the base body; and a base body connector connecting the two base bodies; wherein the width of each mounting groove is greater than the width of the foot support structure but less than twice the width of the foot support structure.

[0006] The base structure provided in this application features a portable base structure installed at the bottom of the foot pad support structure. This effectively increases the contact area with the ground, resulting in greater stability, especially in outdoor environments. Furthermore, since the base structure and energy storage device are detachable, it is more convenient to carry; the base structure can be installed when needed and stored away when not in use. Additionally, the base structure can also be used to increase the height of the energy storage device when height is required.

[0007] In addition, the two bases intersect in the length direction, meaning they are not parallel. Each mounting slot can only accommodate one foot pad support structure in the width direction, making the overall size smaller, easier to carry outdoors, and lower in cost.

[0008] In the above technical solution, optionally, the width of each mounting groove is greater than or equal to 1.4 times the width of the foot pad support structure and less than or equal to 1.6 times the width of the foot pad support structure.

[0009] In this technical solution, the ratio of the width of the mounting groove to the width of the foot pad support structure is further limited, which is more conducive to the installation of the foot pad support structure and will not make the overall volume of the base structure too large.

[0010] In the above technical solution, optionally, the included angle between the length directions of the two seats is greater than or equal to 50° and less than or equal to 70°.

[0011] In this technical solution, the included angle between the two bases is defined, which allows for a better match with the four foot pad support structure of the energy storage device.

[0012] Optionally, in the above technical solution, the seat connector and the seat are an integral structure.

[0013] In this technical solution, the seat connector and the seat are an integral structure, which can improve the connection strength between the two.

[0014] Optionally, in the above technical solution, the seat connector and the seat are detachably connected.

[0015] In this technical solution, when the load weight of the top energy storage device is small, it can be supported by a split base alone; when the load weight of the energy storage device is large, a base connector is set between the two bases to improve the overall connection strength of the base, thereby improving the stability of the energy storage device, so that the base structure of this application is suitable for different load scenarios.

[0016] In the above technical solution, optionally, the seat body includes: a surrounding plate; a base plate, connected to the surrounding plate and capable of defining an installation groove with the surrounding plate; and a foot pad support structure capable of extending into the installation groove from the opening of the installation groove and being detachably connected to the base plate.

[0017] In this technical solution, the mounting groove is formed by the surrounding plate and the base plate, which is simple and reliable. The foot pad support structure can be inserted from the groove and connected to the base plate to achieve quick installation and stable support.

[0018] In the above technical solution, optionally, the lower end face of the seat connector away from the energy storage device is coplanar with the lower end face of the base plate away from the energy storage device.

[0019] In this technical solution, the seat connector and the base plate make contact with the ground simultaneously, thereby increasing the contact area with the ground and improving stability.

[0020] Optionally, in the above technical solution, the base structure of the energy storage device further includes: a mounting hole penetrating the base plate; and a locking member that can pass through the mounting hole and connect to the foot pad support structure from the side of the base plate away from the foot pad support structure.

[0021] In this technical solution, the foot pads are detachably connected through the mounting holes and locking components on the base plate, which facilitates the installation and disassembly of the base structure and enhances portability and ease of maintenance.

[0022] Optionally, in the above technical solution, the base structure of the energy storage device further includes: a pad, which is disposed in the mounting groove and is detachably connected to the base plate, and a locking member can pass through the mounting hole and the pad in sequence from the side of the base plate away from the foot pad support structure, and be connected to the foot pad support structure.

[0023] In this technical solution, pads can be added to increase the overall height of the energy storage device according to different height requirements. When the height requirement of the energy storage device is small, the pads can also be removed from the mounting slot to reduce the overall weight of the energy storage device and facilitate movement.

[0024] Optionally, in the above technical solution, the base structure of the energy storage device may further include: a flange structure, located at the end of the enclosure away from the base plate, and bent toward the inside of the mounting groove.

[0025] In this technical solution, the flanged structure bends inward to prevent the foot pad support structure from coming out of the mounting groove, thereby improving connection reliability and preventing accidental separation during handling.

[0026] In the above technical solution, optionally, the mounting groove is square in shape and the foot pad support structure is cylindrical.

[0027] The second aspect of this utility model provides an energy storage device, including: a housing, the bottom of which is provided with four foot support structures; and a base structure of the energy storage device as described in any of the technical solutions of the first aspect of this application, wherein one base is used to connect two foot support structures, and the other base is used to connect two other foot support structures.

[0028] Since the energy storage device provided in this application includes the base structure of the energy storage device of any of the technical solutions of the first aspect of this application, it has all the beneficial effects of the base structure of the energy storage device.

[0039] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0040] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0041] like Figure 1 , Figure 3 , Figure 5 and Figure 7As shown, the first aspect of this utility model provides a base structure 1 for an energy storage device. The energy storage device 2 includes four foot support structures 22. The base structure 1 of the energy storage device includes two base bodies 11 and a base body connector 12. The length directions of the two base bodies 11 intersect, that is, the two base bodies 11 are arranged at an angle to each other. One base body 11 is used to connect the two foot support structures 22, and the other base body 11 is used to connect the other two foot support structures 22. The base body 11 includes a mounting groove 116. The two foot support structures 22 can extend into the mounting groove 116 from the slot 1162 of the mounting groove 116 and are detachably connected to the base body 11. The base body connector 12 is connected between the two base bodies 11.

[0042] The base structure provided in this application has a portable base structure installed at the bottom of the foot pad support structure 22, which effectively increases the contact area with the ground, resulting in higher stability for outdoor scenarios. Furthermore, since the base structure and energy storage device 2 are detachable, it is more convenient to carry; that is, the base structure can be installed when needed and stored away when not in use. Moreover, the base structure can also increase the height of the energy storage device 2 when height is required.

[0043] Furthermore, the length directions of the two bases 11 intersect, meaning the two bases 11 are not parallel. This allows the base structure of this application to better match the four foot support structures 22 of the energy storage device 2. Understandably, the four foot support structures 22 of the energy storage device 2 of this application are divided into two groups, each group including two foot support structures 22. The two groups of foot support structures 22 are relatively inclined, or in other words, the line connecting the geometric centers of the four foot support structures 22 is not a standard square structure, but an isosceles trapezoidal structure. Thus, the two bases 11 of this application are relatively inclined, which allows them to match the structure of the four foot support structures 22.

[0044] In addition, the mounting slot 116 of this application can be square in shape, and the foot pad support structure 22 can be cylindrical in shape. The width of each mounting slot 116 is greater than the width of the foot pad support structure 22, but less than twice the width of the foot pad support structure 22. The width of the foot pad support structure 22 is also the diameter of the foot pad support. In other words, the width of the mounting slot 116 is greater than the diameter of the foot pad support structure 22, but less than twice the diameter of the foot pad support structure 22. In this way, each mounting slot 116 can only accommodate one foot pad support structure 22 in the width direction, making its overall volume small, more convenient for outdoor carrying, and lower in cost.

[0045] Of course, the shape of the foot pad support structure 22 can also be a square or a cuboid, etc.

[0046] In the above technical solution, optionally, the width of each mounting groove 116 is greater than or equal to 1.4 times the width of the foot pad support structure 22, and less than or equal to 1.6 times the width of the foot pad support structure 22.

[0047] In this technical solution, the ratio of the width of the mounting groove 116 to the width of the foot pad support structure 22 is further limited. The width of the mounting groove 116 is greater than or equal to 1.4 times the width of the foot pad support structure 22, which is more conducive to the installation of the foot pad support structure 22. The width of the mounting groove 116 is limited to less than or equal to 1.6 times the width of the foot pad support structure 22, so as not to make the overall volume of the base structure too large.

[0048] Optionally, the width of the mounting groove 116 is equal to 1.5 times the width of the foot pad support structure 22.

[0049] In the above technical solution, optionally, the included angle between the length directions of the two bases 11 is greater than or equal to 50° and less than or equal to 70°.

[0050] In this technical solution, the included angle between the two bases 11 is defined so that it can better match the four foot pad support structures 22 of the energy storage device 2.

[0051] In the above technical solution, optionally, the seat connector 12 and the seat 11 are an integral structure. Of course, the seat connector 12 and the seat 11 can also be detachably connected.

[0052] In this technical solution, the base connector 12 and the base 11 are an integral structure, which can improve the connection strength between the two. In addition, the base connector 12 and the base 11 can also be detachably connected according to the requirements. When the load weight of the top energy storage device 2 is small, it can be supported by the split base 11 alone; when the load weight of the energy storage device 2 is large, the base connector 12 is set between the two bases 11 to improve the overall connection strength of the base 11, thereby improving the stability of the energy storage device 2, so that the base structure of this application is suitable for different load scenarios.

[0053] Optionally, when the seat connector 12 and the seat 11 need to be detachably connected, each seat 11 is provided with a limiting port, and the end of the seat connector 12 that connects to the two seats 11 is provided with a mounting structure. Each mounting structure can be interference-fitted with the corresponding limiting port, so that the mounting structure is limited within the limiting port, thereby realizing the detachable connection between the seat connector 12 and the seat 11. The connection between the seat connector 12 and the seat 11 is realized through the interference fit between the mounting structure and the limiting port. The connection structure is simple, and disassembly is very convenient, improving disassembly efficiency.

[0054] In the above technical solution, optionally, the seat 11 includes a surrounding plate 113 and a bottom plate 117. The bottom plate 117 is connected to the surrounding plate 113 and can define an installation groove 116 with the surrounding plate 113. The foot pad support structure 22 can extend into the installation groove 116 from the slot 1162 of the installation groove 116 and be detachably connected to the bottom plate 117.

[0055] In this technical solution, the mounting groove 116 is formed by the surrounding plate 113 and the base plate 117. The structure is simple and reliable. The foot pad support structure 22 can be inserted from the groove 1162 and connected to the base plate 117 to achieve quick installation and stable support.

[0056] It should be understood that the base plate 117 of this application is a square plate, the length direction of the base body 11 is also the length direction of the base plate 117, and the width of the mounting groove 116 is also the width of the base plate 117.

[0057] The enclosure 113 can be formed by connecting multiple square plates end to end, and two adjacent square plates can be welded together to improve the connection strength between them.

[0058] In the above technical solution, optionally, the lower end surface of the seat connector 12 away from the energy storage device 2 is coplanar with the lower end surface of the base plate 117 away from the energy storage device 2.

[0059] In this technical solution, the seat connector 12 and the base plate 117 are in contact with the ground simultaneously, thereby increasing the contact area with the ground and improving stability.

[0060] In the above technical solutions, optionally, such as Figure 2 As shown, the base structure 1 of the energy storage device also includes a mounting hole 162 and a locking member 164. The mounting hole 162 penetrates the base plate 117; the locking member 164 can pass through the mounting hole 162 and connect to the foot pad support structure 22 from the side of the base plate 117 away from the foot pad support structure 22.

[0061] In this technical solution, the mounting hole 162 can be a threaded hole, the locking element 164 can be a locking bolt, and the end face of the foot pad support structure 22 near the base plate 117 can be provided with a threaded hole, so that the locking bolt can pass through the threaded hole of the base plate 117 and then cooperate with the threaded hole of the foot pad support structure 22, thereby realizing the connection between the foot pad support structure 22 and the base structure.

[0062] This application enables the foot pads to be detachably connected through the mounting holes 162 and locking parts 164 on the base plate 117, which facilitates the installation and disassembly of the base structure and enhances portability and maintenance convenience.

[0063] In the above technical solutions, optionally, such as Figure 4As shown, the base structure 1 of the energy storage device also includes a pad 15, which is disposed in the mounting groove 116 and is detachably connected to the base plate 117. The locking member 164 can pass through the mounting hole 162 and the pad 15 in sequence from the side of the base plate 117 away from the foot pad support structure 22, and is connected to the foot pad support structure 22.

[0064] In this technical solution, multiple detachable pads 15 can be provided in the mounting groove 116, and then clearance holes are provided on the pads 15. In this way, the locking member 164 can pass through the mounting hole 162 and the clearance hole of the pad 15 in sequence from the side of the base plate 117 away from the foot pad support structure 22, and connect with the foot pad support structure 22.

[0065] Depending on the different height requirements, different numbers of pads 15 can be added to increase the overall height of the energy storage device 2. The number of pads 15 can be set to 2 or 4. When the height requirement of the energy storage device 2 is small, the pads 15 can also be removed from the mounting groove 116 to reduce the overall weight of the energy storage device 2 and facilitate movement.

[0066] Optionally, in the above technical solution, the base structure 1 of the energy storage device also includes a flange structure 118, which is located at the end of the enclosure 113 away from the bottom plate 117 and bends inward toward the mounting groove 116.

[0067] In this technical solution, the flange structure 118 bends inward to prevent the foot pad support structure 22 from coming out of the mounting groove 116 and avoid accidental separation during transportation.

[0068] like Figure 6 As shown, the second aspect of this utility model provides an energy storage device 2, including: a housing 24, the bottom of which is provided with four foot support structures 22; and a base structure 1 of the energy storage device as described in any of the technical solutions of the first aspect of this application, wherein one base 11 is used to connect two foot support structures 22, and the other base 11 is used to connect the other two foot support structures 22.

[0069] Since the energy storage device 2 provided in this application includes the base structure 1 of the energy storage device of any of the technical solutions of the first aspect of this application, it has all the beneficial effects of the base structure 1 of the energy storage device.
