Description

Technical Field

[0001] This utility model relates to the field of energy storage equipment technology, and in particular to a pull-out module for energy storage equipment and an energy storage equipment. Background Technology

[0002] like Figure 1 and Figure 2 As shown, in energy storage devices, for ease of maintenance, the internal electrical control components, fan components, etc., are usually made into box-shaped pull-out modules 10, which are inserted into the energy storage housing 20. The energy storage housing 20 is provided with a fixed base 30. A limiting member 40 is provided on the rear side of the pull-out module 10. A limiting hole 301 is opened on the fixed base 30. The pull-out module 10 is limited by the limiting member 40 at its rear end passing through the limiting hole 301 of the fixed base 30. The size of the limiting hole 301 is larger than the diameter of the limiting member 40, so that the limiting member 40 on the pull-out module 10 can be inserted. The front side of the pull-out module 10 is then fixed to the fixed base 30 with a folding plate and screws.

[0003] Because there is a gap between the limiting member 40 and the limiting hole 301, during vibration simulation on a vibration table or during actual vehicle transportation tests on the road, the rear end of the pull-out module 10 will continuously bounce. The impact force generated by this bouncing causes the limiting member 40 to continuously strike the wall of the limiting hole 301, producing a lot of noise. Furthermore, since the front end of the pull-out module 10 is fixed, the repeated bouncing of the rear end is equivalent to a lever arm repeatedly bending, which can cause fatigue tearing of the fixed front end. Secondly, because there is a gap between the limiting member 40 and the limiting hole 301, even under stable operating conditions, other vibration sources can easily introduce excitation force into this part, causing vibration and resulting in direct collision between the limiting member 40 and the limiting hole 301, generating significant noise.

[0004] Therefore, there is an urgent need to provide a pull-out module and energy storage device for energy storage equipment to solve the above problems. Utility Model Content

[0005] One objective of this invention is to provide a pull-out module for energy storage devices that can prevent the limiting component from directly contacting the wall of the limiting hole and generating noise, and can attenuate the impact force generated by vibration, reduce the amplitude of the pull-out module's swaying, and avoid fatigue tearing of the front fixed part.

[0006] Another objective of this invention is to provide an energy storage device that can prevent the limiting component from colliding with the wall of the limiting hole and generating noise, reduce the relative movement between the pull-out module and the energy storage shell, and prevent fatigue tearing of the fixed part at the front end of the pull-out module.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] A pull-out module for an energy storage device, comprising:

[0009] The pull-out module and the fixed base are provided. The pull-out module is slidably disposed on the fixed base in the front-back direction. The front end of the pull-out module is detachably connected to the fixed base. One of the fixed base and the rear end of the pull-out module is provided with a limiting hole, and the other of the two is provided with a limiting member.

[0010] An elastic sleeve is fitted over the aforementioned limiting member, and the elastic sleeve is inserted into the aforementioned limiting hole, with the elastic sleeve abutting against the wall of the aforementioned limiting hole.

[0011] As an optional solution, the rear end of the pull-out module is provided with the aforementioned limiting component, and the aforementioned limiting hole is provided on the aforementioned fixed base.

[0012] As an alternative, the aforementioned elastic component is a hollow frustum shape, with its outer diameter gradually decreasing from front to back, and the minimum outer diameter of the elastic component being smaller than the diameter of the aforementioned limiting hole.

[0013] As an optional solution, the maximum outer diameter of the aforementioned elastic component is larger than the diameter of the aforementioned limiting hole.

[0014] As an optional solution, the aforementioned elastic kit is made of rubber.

[0015] As an optional solution, the pull-out module for the energy storage device also includes a fixing kit, which is axially limited and sleeved on the elastic kit and fixedly connected to the pull-out module.

[0016] As an alternative, the inner diameter of the aforementioned fixing kit gradually decreases from front to back and fits snugly against the outer surface of the aforementioned elastic kit.

[0017] As an optional solution, the peripheral side of the aforementioned fixing kit is provided with a flange, and the flange is provided with at least two connection holes. The aforementioned pull-out module for energy storage devices also includes at least two first fasteners, which pass through the corresponding connection holes and are fixedly connected to the aforementioned pull-out module.

[0018] As an optional solution, the number of the aforementioned limiting members is set to at least two, each of the aforementioned limiting members is fitted with the aforementioned elastic sleeve, and the number of the aforementioned limiting holes is set to at least two, with the aforementioned limiting members and the aforementioned limiting holes corresponding one-to-one.

[0019] An energy storage device includes an energy storage housing and a pull-out module for the energy storage device, wherein the fixed base is fixed inside the energy storage housing, and the pull-out module can slide relative to the fixed base to the inside or outside of the energy storage housing.

[0020] The beneficial effects of this utility model are:

[0021] This utility model provides a pull-out module for energy storage equipment. When maintenance is required, the front end of the pull-out module can be disassembled from the fixed base. Then, the pull-out module is pulled outward relative to the fixed base in the front-back direction for easy maintenance. When the pull-out module is pushed inward into place, the limiting member with an elastic sleeve is inserted into the limiting hole for limiting, and then the front end of the pull-out module is fixed to the fixed base. By using an elastic sleeve on the limiting member, the elastic sleeve can abut against the wall of the limiting hole and has a certain preload. During vibration testing or road transportation, the elastic damping effect of the elastic sleeve not only attenuates the impact force generated by vibration but also greatly reduces the amplitude of the pull-out module's bumps and undulations, avoiding fatigue tearing of the front fixed part. Furthermore, the elastic sleeve is located between the limiting member and the limiting hole, preventing the limiting member from directly contacting the wall of the limiting hole during operation, transportation, or testing, thus avoiding noise.

[0022] This utility model also provides an energy storage device. By using the above-mentioned pull-out module for energy storage devices, when conducting vibration tests or road transportation of the energy storage device, by fitting an elastic sleeve onto the limiting member of the pull-out module, the elastic sleeve abuts against the fixed base of the energy storage shell, preventing the limiting member from colliding with the fixed base and generating noise. Due to the elastic damping effect of the elastic sleeve, the relative movement between the pull-out module and the energy storage shell is reduced, avoiding fatigue tearing of the fixed part at the front end of the pull-out module.

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.

[0038] 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.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0040] In the description of this embodiment, the terms "upper," "lower," "left," "right," 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.

[0041] The following is in conjunction with the appendix Figure 3-7 The technical solution of this utility model will be further illustrated through specific implementation methods.

[0042] like Figure 3 and Figure 4 As shown, this embodiment provides a pull-out module for an energy storage device and an energy storage device. The energy storage device includes an energy storage housing 2 and the aforementioned pull-out module. Specifically, the pull-out module includes a pull-out module 1 and a fixed base 3. The fixed base 3 is fixed inside the energy storage housing 2. The pull-out module 1 is slidably mounted on the fixed base 3 in the front-to-back direction, allowing it to slide relative to the fixed base 3 to the inside or outside of the energy storage housing 2 for easy removal for maintenance or replacement. The front end of the pull-out module 1 is detachably connected to the fixed base 3. When the pull-out module 1 needs to be removed, the fixing at the front end of the pull-out module 1 is removed, and the pull-out module 1 is pulled out of the energy storage housing 2 for maintenance or replacement. One of the fixed base 3 and the rear end of the pull-out module 1 has a limiting hole 31, and the other has a limiting member 4. After the pull-out module 1 is pushed into the energy storage housing 2, the rear end of the pull-out module 1 is fixed to the fixed base 3 by the cooperation of the limiting member 4 and the limiting hole 31.

[0043] like Figure 4 As shown, the pull-out module for energy storage equipment also includes an elastic sleeve 5. The elastic sleeve 5 is fitted outside the limiting member 4 and is inserted into the limiting hole 31, with the elastic sleeve 5 abutting against the hole wall of the limiting hole 31. The elastic sleeve 5 can prevent the limiting member 4 and the limiting hole 31 from directly contacting each other, thereby preventing the limiting member 4 from colliding with the hole wall of the limiting hole 31 and generating noise. Furthermore, during vibration testing or road transportation of the equipment, due to the elastic damping effect of the elastic sleeve 5, not only is the impact force generated by the vibration of the pull-out module 1 and the fixed base 3 on each other attenuated, but the amplitude of the bumps and undulations of the pull-out module 1 is also greatly reduced, avoiding fatigue tearing of the fixed part at the front end of the pull-out module 1.

[0044] In this embodiment, as Figure 3 , Figure 4 and Figure 5As shown, a limiting component 4 is provided at the rear end of the pull-out module 1, and a limiting hole 31 is provided on the fixed base 3. The limiting component 4 is provided on the pull-out module 1, and the elastic sleeve 5 is fitted on the limiting component 4, which facilitates the pull-out module 1 to be pulled out and the elastic sleeve 5 to be replaced. This avoids problems such as the elastic sleeve 5 not being able to fully abut against the wall of the limiting hole 31 due to wear or aging of the elastic sleeve 5, which would cause the pull-out module 1 to bounce and undulate, and fatigue tearing of the front fixed part of the pull-out module 1.

[0045] In some alternative embodiments, a limiting hole 31 can be opened at the rear end of the pull-out module 1, and a limiting member 4 can be provided on the fixed base 3, which can also achieve the limiting and fixing of the rear end of the pull-out module 1, which will not be described in detail here.

[0046] In this embodiment, as Figure 6 As shown, the elastic component 5 is a hollow frustum shape, with its outer diameter gradually decreasing from front to back. The frustum shape serves a guiding function. The frustum-shaped elastic component 5 includes a large end face 52 and a small end face 51. The large end face 52 of the elastic component 5 can abut against the rear end of the pull-out module 1, and the small end face 51 of the elastic component 5 is used to pass through the limiting hole 31. The minimum outer diameter of the elastic component 5 is smaller than the diameter of the limiting hole 31; that is, the minimum outer diameter of the elastic component 5 is the outer diameter of the small end face 51 of the elastic component 5. By setting the minimum outer diameter of the elastic component 5 to be smaller than the diameter of the limiting hole 31, when the pull-out module 1 slides backward along the fixed base 3, the small end face 51 of the elastic component 5 can easily insert into the limiting hole 31.

[0047] In some alternative embodiments, the elastic kit 5 may also be configured as a hollow cone, a combination of a frustum and a cone, a combination of a cylinder and a frustum, a combination of a cylinder and a cone, etc., with an outer diameter that gradually decreases from front to back and the minimum outer diameter being smaller than the diameter of the limiting hole 31, without specific limitations here.

[0048] In this embodiment, as Figure 5 As shown, the maximum outer diameter of the elastic component 5 is greater than the diameter of the limiting hole 31. It can be understood that the maximum outer diameter of the elastic component 5 is the outer diameter of the large end face 52 of the elastic component 5. The larger size of the large end face 52 than the size of the limiting hole 31 ensures that the elastic component 5 is axially limited within the limiting hole 31, and the middle section of the side of the elastic component 5 abuts against the wall of the limiting hole 31, providing a certain pre-tightening force. Furthermore, it prevents the fixed base 3 from directly contacting the rear end of the pull-out module 1, thus avoiding noise.

[0049] In this embodiment, the elastic component 5 is a rubber part. Rubber has high elasticity and can deform under external impact, returning to its shape after the external force is removed. Through the properties of rubber, the impact force generated by vibration can be attenuated, reducing the amplitude of the swaying of the pull-out module 1, and preventing fatigue tearing of the front fixing part caused by the continuous swaying of the rear end of the pull-out module 1.

[0050] In some alternative embodiments, the elastic kit 5 may also be a material with elastic damping properties, such as cork or silicone, without specific limitations.

[0051] In this embodiment, specifically, as follows: Figure 4 As shown, a first folding plate 32 is provided on the fixed base 3. One end of the first folding plate 32 is horizontally set and fixedly connected to the fixed base 3, and the other end of the first folding plate 32 is vertically set and has the aforementioned limiting hole 31.

[0052] In this embodiment, as Figure 4 , Figure 5 and Figure 7 As shown, the pull-out module for energy storage devices also includes a fixing kit 6. The fixing kit 6 is axially limited and sleeved on the elastic kit 5 and fixedly connected to the pull-out module 1. The fixing kit 6 can fix the elastic kit 5, which is sleeved on the limiting member 4, to the pull-out module 1, preventing the elastic kit 5 from detaching from the limiting member 4 during the pulling and moving of the pull-out module 1. For example... Figure 5 As shown, since the elastic component 5 is a hollow frustum shape, and its middle section is axially limited within the limiting hole 31, the fixing component 6 does not contact the first folding plate 32.

[0053] Specifically, in this embodiment, the inner diameter of the fixing kit 6 gradually decreases from front to back and fits snugly against the outer surface of the elastic kit 5. Optionally, the inner hole of the fixing kit 6 is conical, and the outer contour of the fixing kit 6 can be cylindrical, frustum-shaped, or other polygonal, without specific limitations. In this embodiment, the outer contour of the fixing kit 6 is frustum-shaped. By setting the inner hole of the fixing kit 6 as a conical hole, its inner contour is consistent with the outer contour of the frustum-shaped elastic kit 5, fitting snugly; and the inner diameter of the front end of the fixing kit 6 is equal to the outer diameter of the large end face 52, avoiding the situation where the inner diameter of the front end of the fixing kit 6 is too large to play a fixing role, or the inner diameter of the front end of the fixing kit 6 is too small to be fixed on the pull-out module 1. By fitting snugly against the outer contour of the elastic kit 5, the fixing kit 6 can play an axial limiting role, thereby indirectly and firmly fixing the elastic kit 5 to the pull-out module 1 through the fixing kit 6.

[0054] In this embodiment, a flange 61 is provided on the periphery of the fixing kit 6. The flange 61 is located on the front side of the fixing kit 6, and at least two connection holes 62 are provided on the flange 61. The pull-out module for the energy storage device also includes at least two first fasteners (not shown). The first fasteners correspond one-to-one with the connection holes 62. The first fasteners pass through the corresponding connection holes 62 and are fixedly connected to the pull-out module 1. In this embodiment, the flange 61 is circular in shape, and there are four connection holes 62. The four connection holes 62 are evenly spaced along the circumference of the flange 61. The first fasteners can be selected as screws. The screws pass through the corresponding connection holes 62 and are threadedly connected to the housing of the pull-out module 1. The fixing kit 6 can be firmly fixed to the rear side of the housing of the pull-out module 1 by the four screws. The material of the fixing kit 6 can be rubber, metal, etc., and can be flexibly set according to actual needs. No specific limitation is made here.

[0055] Of course, in other alternative embodiments, the number of connecting holes 62 and the first fastener can also be set to two, three or more, which can be flexibly set according to actual needs, and no specific limitation is made here.

[0056] In actual operation, the elastic component 5 is first fitted onto the limiting component 4, and the fixing component 6 is fitted onto the elastic component 5. The fixing component 6 is then connected to the housing of the pull-out module 1 using the first fastener, thus fixing the elastic component 5. Next, the pull-out module 1 is pushed backward along the fixing base 3 into the energy storage housing 2. The elastic component 5 passes through the limiting hole 31, generating a certain pre-tightening force to fix the rear end of the pull-out module 1. Then, the front end of the pull-out module 1 is fixed to the fixing base 3. During maintenance of the pull-out module 1, the fixing at the front end of the pull-out module 1 is removed, and the pull-out module 1 is pulled forward directly out of the energy storage housing 2 for maintenance. Alternatively, either the elastic component 5 or the fixing component 6 can be replaced.

[0057] In some alternative embodiments, the elastic kit 5 can also be fixed to the pull-out module 1 or the limiting member 4 in other ways. For example, the elastic kit 5 can be glued or snapped onto the pull-out module 1 or the limiting member 4, or the fixing kit 6 and the elastic kit 5 can be integrated into one piece.

[0058] In this embodiment, combined with Figure 4The pull-out module 1 housing has two limiting members 4, which are horizontally arranged on the lower rear side of the housing. Each limiting member 4 is fitted with an elastic sleeve 5. There are also two limiting holes 31, with each limiting member 4 corresponding to one limiting hole 31. By using two limiting members 4 and two limiting holes 31, the lateral torsional force generated by the pull-out module 1 due to vibration can be reduced, thus reducing fatigue and tearing of the front-end fixing part. In some alternative embodiments, the number of limiting members 4 and limiting holes 31 can be three, four, or more, depending on actual needs; no specific limitation is made here.

[0059] In this embodiment, the limiting member 4 can be a pin. Furthermore, in other optional embodiments, the limiting member 4 can also be a screw, bolt, or other structure that can achieve the limiting function and allow the installation of the elastic sleeve 5. It can be flexibly set according to actual needs, and no specific limitations are made here.

[0060] In this embodiment, as Figure 8 As shown, the front end of the pull-out module 1 is detachably connected to the fixed base 3 via a second folding plate 33. Specifically, one end of the second folding plate 33 is horizontally positioned and has a first fixing hole 331. A second fastener (not shown) passes through the first fixing hole 331 and is threadedly connected to the fixed base 3. The other end of the second folding plate 33 is vertically positioned and has two second fixing holes 332. A third fastener (not shown) passes through the second fixing holes 332 and is threadedly connected to the front side of the pull-out module 1's housing. The number of third fasteners corresponds to the number of second fixing holes 332. Optionally, the second and third fasteners are screws. A handle 11 is provided on the front end of the housing of the pull-out module 1. When the pull-out module 1 needs to be removed, the second and third fasteners are removed directly, the second folding plate 33 is removed, and then the pull-out module 1 is pulled out through the handle 11 for inspection or replacement. When the pull-out module 1 is pushed into the energy storage housing 2, the elastic kit 5 is first inserted into the limiting hole 31 to achieve the limiting, then the second folding plate 33 at the front end is installed, and finally the second and third fasteners are locked. The operation is convenient and quick.

[0061] In some alternative embodiments, the number of the first fixing hole 331 and the second fastener can also be set to two, three, four or more, depending on actual needs, and no specific limitation is made here. Similarly, the number of the second fixing hole 332 and the third fastener can also be set to one, three, four or more, depending on actual needs, and no specific limitation is made here.

[0062] In some alternative embodiments, a groove is provided on the sliding mating surface of one of the fixed base 3 and the pull-out module 1, and a protrusion is provided on the sliding mating surface of the other. The groove and the protrusion slide in a sliding engagement. The pull-out module 1 slides back and forth on the fixed base 3 through the engagement of the groove and the protrusion, which can guide the back and forth movement of the pull-out module 1, thereby guiding the elastic kit 5 to quickly pass through the limiting hole 31.

[0063] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
