[0052] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0053] like Figures 1 to 3 As shown, this utility model provides a vibration damping device 1, including a vibration damper 11 and a load-bearing component 12.

[0054] Furthermore, the shock absorber 11 includes a support 111, a limiting support 112, and an elastic element 113.

[0055] The support 111 includes a receiving space with a top opening, and at least a portion of the limiting support 112 is located within the receiving space. Specifically, the bottom of the limiting support 112 is spaced apart from the bottom surface of the inner wall of the support 111, and the top of the limiting support 112 extends upward beyond the receiving space, so that there is a gap between the top surface of the limiting support 112 and the top surface of the support 111.

[0056] Specifically, the support 111 and the limiting support 112 in this utility model can be hollow cylindrical structures, but are not limited to this. The support 111 and the limiting support 112 can also be prismatic or other shapes other than cylindrical. The specific design can be made according to the actual situation.

[0057] It should be noted that, in the aforementioned embodiment, the top of the support 111 is vertically above it, and the bottom of the support 111 is vertically below it. Similarly, the top of the limiting support 112 is vertically above it, and the bottom of the limiting support 112 is vertically below it. In this utility model, the top surface of the limiting support 112 refers to the side of the limiting support 112 away from the bottom surface of the support 111. The top of the limiting support 112 refers to the portion of the limiting support 112 away from the support 111, wherein the top of the limiting support 112 may include the top surface of the limiting support 112 and a portion of the side circumferential surface of the limiting support 112.

[0058] The limiting support 112 includes a receiving space with a bottom opening, and at least a portion of the elastic member 113 is located within the receiving space. The bottom of the elastic member 113 abuts against the bottom surface of the inner wall of the supporting support 111, and the top of the elastic member 113 abuts against the top surface of the inner wall of the limiting support 112.

[0059] Specifically, the elastic element 113 in this utility model can be a spring, but it is not limited to this. Other structures that can absorb and release the force of the limiting support 112 in the vertical direction through elastic deformation can also be used as the elastic element 113 in this utility model.

[0060] It should be noted that the present invention can directly place the elastic element 113 in the receiving space so that the top and bottom of the elastic element 113 abut against the top surface of the inner wall of the limiting support 112 and the bottom surface of the inner wall of the supporting support 111, respectively. However, it is not limited to this. In order to avoid the elastic element 113 from shifting position, the present invention can also fix the top of the elastic element 113 to the top surface of the inner wall of the limiting support 112 and fix the bottom of the elastic element 113 to the bottom surface of the inner wall of the supporting support 111.

[0061] The support assembly 12 is connected to the top of the limiting support 112, and the support assembly 12 has a support surface for supporting the battery pack.

[0062] Specifically, in this utility model, the bottom of the bearing component 12 is connected to the top surface of the limiting support 112, and the top surface of the bearing component 12 is the bearing surface for bearing the battery pack.

[0063] In this embodiment of the present invention, the limiting support 112 can move up and down relative to the supporting support 111 under external force, so that the top surface of the inner wall of the limiting support 112 can abut against the top of the elastic member 113 and compress the elastic member 113. Thus, when the vibration damping device 1 is subjected to vibration and causes the limiting support 112 and the bearing component 12 to move up and down relative to the supporting support 111, the elastic member 113 can reciprocate up and down to absorb and release a portion of the vertical force of the limiting support 112, thereby reducing the amplitude of the vibration damping device 1. This can further reduce the vibration excitation of the battery pack on the vibration damping device 1, thereby reducing the risk of a strong collision between the battery pack and the bearing component 12 and other structures, and thus reducing the possibility of damage to the battery pack and the vibration damping device 1, thereby extending the service life of the battery pack and the vibration damping device 1.

[0064] For example, the vibration damping device 1 of this utility model can be placed inside a mobile energy storage vehicle, and the battery pack is placed on the bearing surface of the bearing component 12 in the vibration damping device 1. When the mobile energy storage vehicle encounters vibration during transportation, the elastic element 113 absorbs and releases at least part of the force of the limiting support 112 in the vertical direction, thereby reducing the vibration excitation of the battery pack placed on the vibration damping device 1. This reduces the risk of a violent collision between the vibration damping device 1 and the battery pack due to vibration, thereby improving the safety of the mobile energy storage vehicle during transportation and ensuring its normal function.

[0065] In some embodiments of this utility model, a guide member 13 may be provided on the support 111. The guide member 13 extends along the central axis of the elastic member 113, and the bottom of the guide member 13 is connected to the bottom surface of the inner wall of the support 111. The top surface of the guide member 13 is not lower than the top surface of the elastic member 113. Specifically, the top surface of the guide member 13 in this utility model can abut against the top surface of the inner wall of the limiting support 112. By providing the guide member 13, the movement of the elastic member 113 other than in the vertical direction can be restricted, so as to ensure that the elastic member 113 always moves up and down in the vertical direction during the elastic expansion and contraction process. This reduces the friction between the elastic member 113 and the limiting support 112, thereby extending the service life of the elastic member 113 and the limiting support 112.

[0066] Furthermore, in this embodiment of the present invention, the supporting component 12 may include a first supporting plate 121, the bottom surface of which is connected to the top surface of the limiting support 112. The guide member 13 passes through the top surface of the limiting support 112 and the first supporting plate 121 and extends upward from the first supporting plate 121, so that the top surface of the guide member 13 is higher than the top surface of the first supporting plate 121.

[0067] The top surface of the guide member 13 is connected to a limiting member 14, which extends outward beyond the guide member 13. That is, except for the portion covering the top surface of the guide member 13, the remaining portion of the limiting member 14 extends away from the central axis of the guide member 13. This prevents the top surface of the limiting member 14 from moving from the through-hole on the top surface of the first bearing plate 121 and the limiting support 112, which allows the guide member 13 to pass through, into the receiving space when the elastic member 113 extends and retracts vertically. This also prevents the limiting support 112 from completely detaching from the receiving space when the elastic member 113 moves upward, thus ensuring the stability of the vibration damper 11 structure. Furthermore, by making the top surface of the limiting member 14 larger than the top surface of the guide member 13, the contact surface with the battery pack can be increased, reducing or avoiding stress concentration in the battery pack and thus lowering the risk of battery pack damage.

[0068] Furthermore, the support assembly 12 may also include a second support plate 122 disposed parallel to and spaced above the first support plate 121, and at least one side support plate 123 connecting the first support plate 121 and the second support plate 122. The limiting member 14 is located between the first support plate 121 and the second support plate 122. When placing the battery pack, the battery pack can be placed directly on the top surface of the second support plate 122, thereby further reducing stress concentration in the battery pack and lowering the risk of battery pack damage.

[0069] In this embodiment of the present invention, one side support plate 123 may be provided in the support assembly 12, but it is not limited to this. Two, three, four, or other numbers of side support plates 123 may also be provided in the support assembly 12. The side support plates 123 enable a fixed connection between the first support plate 121 and the second support plate 122. The more side support plates 123 there are, the greater the structural strength of the support assembly 12. By providing multiple side support plates 123, the present invention increases the load-bearing capacity and vibration resistance of the support assembly 12 for the battery pack, thereby reducing the risk of damage to the support assembly 12 and extending its service life.

[0070] In this invention, the side support plate 123 can be arranged perpendicular to the first support plate 121. The opposite ends of the side support plate 123 can be connected to the ends of the first support plate 121 and the second support plate 122, respectively. However, this is not a limitation; the side support plate 123 can also be arranged at an angle relative to the first support plate 121, that is, the included angle between the side support plate 123 and the first support plate 121 is less than 90°. The side support plate 123 can also be arranged at any position on the first support plate 121 and the second support plate 122 except for the ends, as long as the limiting support 112 can avoid contact between the limiting member 14 and the side support plate 123 when it moves up and down relative to the corresponding supporting support 111.

[0071] In addition, to facilitate the installation of the vibration damping device 1, the present invention can also provide a first through hole corresponding to the limiting member 14 on the second bearing plate 122 for mounting the elastic member 113. The orthographic projection of the limiting member 14 on the second bearing plate 122 is located in the first through hole. Thus, after the guide member 13 passes through the limiting support 112 and the first bearing plate 121, the limiting member 14 can be placed in the gap between the first bearing plate 121 and the second bearing plate 122 through the first through hole on the second bearing plate 122 to achieve a fixed connection between the limiting member 14 and the guide member 13.

[0072] Specifically, the installation sequence of the vibration damping device 1 in this embodiment of the present invention can be as follows: First, place the elastic member 113 in the accommodating space so that the bottom of the elastic member 113 abuts against the bottom of the inner wall of the support 111. Position the bottom opening of the limiting support 112 directly opposite the spring so that the limiting support 112 is placed in the accommodating space and the top surface of the inner wall of the limiting support 112 abuts against the elastic member 113. When the vibration damping device 1 includes a guide member 13, the guide member 13 can be placed in the accommodating space before the elastic member 113 is placed there, and the bottom of the guide member 13 is fixedly connected to the bottom of the inner wall of the support 111; when the limiting support 112 is placed in the accommodating space, the top of the guide member 13 penetrates the top surface of the limiting support 112. After completing the installation of the vibration damper 11, place the bearing assembly 12 on top of the limiting support 112. The top of the guide member 13 in the support 111 can pass through the first bearing plate 121 to protrude from the top surface of the first bearing plate 121. The limiting member 14 is placed on the top surface of the guide member 13 through the first through hole on the second bearing plate 122, thereby realizing the fixed connection between the limiting member 14 and the guide member 13.

[0073] It should be noted that, in this embodiment of the invention, the vibration damping device 1 may include a plurality of vibration dampers 11, which may be arranged in an array at intervals along the extending direction of the bearing component 12. By providing a plurality of vibration dampers 11 within the vibration damping device 1, the vibration excitation experienced by the battery pack on the vibration damping device 1 can be further reduced, thereby reducing the risk of a violent collision between the battery pack and the vibration damping device 1, and thus reducing the possibility of damage to the battery pack.

[0074] When the second bearing plate 122 in the vibration damping device 1 is provided with a first through hole, there can be multiple first through holes on the second bearing plate 122, and the first through holes on the second bearing plate 122 correspond one-to-one with the vibration dampers 11 in the vibration damping device 1. Thus, the limiting member 14 in each vibration damper 11 can enter the gap between the first bearing plate 121 and the second bearing plate 122 through the first through hole on the second bearing plate 122, thereby realizing the fixed connection between the limiting member 14 and the guide member 13.

[0075] In this embodiment of the invention, the vibration damping device 1 may further include a fixing structure 15. When the battery pack is placed on the bearing surface of the bearing component 12, the fixing structure 15 is connected to both the bearing component 12 and the battery pack, thereby achieving a fixed connection between the battery pack and the vibration damping device 1. When the battery pack encounters vibration, it remains connected to the vibration damping device 1 to reduce the vibration excitation it receives, thus reducing the risk of damage to the battery pack.

[0076] It should be noted that the fixing structure 15 in this utility model can be a plate-shaped structure. In this case, the upper and lower ends of the fixing structure 15 can be fixedly connected to the battery pack and the supporting component 12 by bolts, respectively. However, it is not limited to this. The fixing structure 15 in this utility model can also be a pin, with one end of the pin fixedly connected to the battery pack and the other end embedded in the supporting component 12, thereby realizing the fixed connection between the battery pack and the supporting component 12.

[0077] Furthermore, the fixing structure 15 in this utility model can be connected to one end of the bearing component 12 along its length, but is not limited thereto. The fixing structure 15 can also be connected to the opposite ends of the bearing component 12 along its length to enhance the stability of the connection between the battery pack and the vibration damping device 1.

[0078] like Figures 4 to 10 As shown, this utility model embodiment also provides a vibration reduction system 2, which may include two parallel and spaced fixed components and two vibration reduction devices 1 as described above, wherein the two vibration reduction devices 1 are arranged in a one-to-one correspondence with the two fixed components.

[0079] Specifically, such as Figure 5 As shown, each of the two fixed components in this utility model is provided with a vibration damping device 1, and the two vibration damping devices 1 together support a battery pack.

[0080] Furthermore, the fixing component in this utility model may include at least one fixing plate 31 and a connector 32.

[0081] Among them, such as Figure 7 As shown, when the fixing structure 15 is only provided at one end of the bearing assembly 12 along its length, a side baffle 34 can also be provided on the fixing plate 31. The side baffle 34 is located at the other end of the bearing assembly 12 along its length. When the battery pack is placed on the bearing assembly 12, the fixing structure 15 and the side baffle 34 are located at opposite ends of the battery pack. By providing the fixing structure 15 and the side baffle 34 at opposite ends of the battery pack, the fixed connection between the battery pack and the bearing assembly 12 is achieved, while the position of the battery pack is strengthened, thereby reducing the risk of the battery pack falling off the bearing assembly 12.

[0082] In this embodiment of the present invention, a second through hole may be provided on the fixing plate 31, and the second through hole on the fixing plate 31 corresponds to the damper 11 in the vibration damping device 1.

[0083] For example, when the vibration damping device 1 includes one vibration damper 11, a second through hole can be provided on the fixing plate 31 corresponding to the vibration damping device 1. When the vibration damping device 1 includes multiple vibration dampers 11, multiple second through holes can be provided on the fixing plate 31 corresponding to the vibration damper 1, and the second through holes correspond one-to-one with the vibration dampers 11 in the vibration damping device 1.

[0084] In this utility model, when the vibration damping device 1 is placed on the fixed plate 31, the orthographic projection of the vibration damper 11 on the fixed plate 31 is located in the corresponding second through hole, so that the vibration damper 11 can pass through the fixed plate 31 through the corresponding second through hole.

[0085] It should be noted that, as Figures 8 to 9 As shown, after the vibration damping device 1 is placed on the fixed plate 31, the top surface of the support 111 is not higher than the top surface of the fixed plate 31, and the top of the limiting support 112 extends upward through the second through hole to the top surface of the fixed plate 31, so as to ensure that there is a gap between the bottom surface of the bearing component 12 and the top surface of the fixed plate 31, so that the bearing component 12 and the limiting support 112 can move up and down relative to the support 111.

[0086] like Figure 10 As shown, the connector 32 may include a sleeve 321 and a first connecting plate 322 disposed on the top of the sleeve 321 and extending outward. The sleeve 321 is fixedly sleeved on the outer periphery of the support 111. The first connecting plate 322 is connected to the bottom surface of the fixing plate 31, thereby realizing the connection and fixation between the vibration damping device 1 and the fixing assembly.

[0087] In this invention, the sleeve 321 may be fitted only onto a portion of the outer periphery of the support 111 to save on manufacturing materials. However, it is not limited to this; the sleeve 321 may also be fitted onto the entire outer periphery of the support 111, with the sleeve body connected to the entire outer peripheral surface of the support 111. This increases the connection area between the sleeve 321 and the support 111, thereby enhancing the stability of the connection between the sleeve 321 and the support 111.

[0088] like Figure 3 and Figure 9 As shown in this embodiment of the present invention, when the battery pack is placed on the supporting component 12, the distance between the top surface of the fixing plate 31 and the bottom surface of the supporting component 12 is defined as H1, and the distance between the bottom surface of the limiting support 112 and the bottom surface of the inner wall of the supporting support 111 is defined as H2. Therefore, H2 > H1. When the supporting component 12 moves downwards and contacts the fixing plate 31, collisions between the limiting support 112 and the bottom surface of the supporting support 111 can be avoided, thereby reducing the risk of damage to the vibration damping device 1 and extending its service life.

[0089] Furthermore, defining the distance between the top surface of the limiting member 14 and the top surface of the second support plate 122 as H3 satisfies that H3 > H1. This ensures that when the support assembly 12 moves downward and contacts the fixed plate 31, the top surface of the limiting member 14 is always lower than the top surface of the second support plate 122. This avoids the situation where the limiting support 112 protrudes upward from the top surface of the second support plate 122 and collides with the battery pack when it moves downward relative to the support 111, thereby reducing the risk of battery pack damage.

[0090] For example, in this embodiment of the present invention, H1 can be 6mm, H2 can be 9mm, and H3 can be 8mm, but it is not limited to these values. H1, H2, and H3 can also be any other values ​​in this invention, so as to reduce the possibility of collision between the limiting support 112 and the supporting support 111, and between the limiting member 14 and the second bearing plate 122, when the limiting support 112 moves up and down relative to the supporting support 111.

[0091] In this embodiment of the utility model, the fixing component may further include a column 33, which is connected to the outer side of the fixing plate 31.

[0092] In this context, the outer side of the fixing plate 31 refers to the side of the fixing plate 31 that faces away from the battery pack.

[0093] It should be noted that the number of columns 33 in the fixing assembly can be one, but is not limited to this. The fixing assembly can also be provided with multiple columns 33, which can be arranged at intervals along the extension direction of the fixing plate 31. By providing multiple columns 33, this utility model can increase the connection area between the fixing plate 31 and the columns 33 in the fixing assembly, thereby enhancing the stability of the fixing assembly structure.

[0094] In this embodiment of the invention, when a column 33 is provided in the fixing assembly, the fixing assembly may include multiple fixing plates 31, which are spaced apart along the extension direction of the column 33. By providing multiple spaced fixing plates 31 on the column 33, this invention allows for the selection of any fixing plate 31 in the fixing assembly to place the battery pack, thereby improving the flexibility of battery pack placement.

[0095] In addition, this utility model can also place multiple battery packs in the vibration reduction system 2 at the same time, with each battery pack placed on a fixed plate 31 on the column 33. While ensuring sufficient power supply for the mobile energy storage vehicle, it also reduces the vibration excitation of multiple battery packs, thereby improving the safety of the mobile energy storage vehicle during transportation and ensuring its normal function.

[0096] Furthermore, in this embodiment of the present invention, the connector 32 may also include a second connecting plate 323, which is located between the first connecting plate 322 and the corresponding column 33, and is connected to both the first connecting plate 322 and the column 33. By providing the second connecting plate 323, the present invention achieves a connection between the vibration damping device 1 and the column 33, thereby reducing the risk of the vibration damping device 1 falling off the column 33 due to unstable connection, and consequently reducing the possibility of battery pack damage.

[0097] It should be noted that when the vibration damping device 1 corresponding to the fixed component is provided with multiple vibration dampers 11, the fixed component may also include multiple columns 33. That is, the columns 33 in the fixed component can be provided one-to-one with the vibration dampers 11 in the corresponding vibration damping device 1, so that each vibration damper 11 can be connected to a column 33 through the second connecting plate 323 in the connector 32.

[0098] For example, when the vibration damping device 1 corresponding to the fixed component is provided with three vibration dampers 11, the fixed component in this utility model may include three columns 33, wherein each vibration damper 11 is fixedly connected to the column 33 through the second connecting plate 323.

[0099] In this embodiment of the invention, the installation sequence of the vibration damping system 2 can be as follows: first, assemble the vibration damping device 1, and then place the assembled vibration damping device 1 on the fixing assembly. When the fixing assembly includes a fixing plate 31, the vibration damper 11 in the vibration damping device 1 is installed through the second through hole on the fixing plate 31, and the support 111 is fixedly connected to the fixing plate 31 through the connector 32. When the fixing assembly includes a column 33, the fixing plate 31 can be installed on the column 33 first, and then the vibration damping device 1 carrying the battery pack can be placed on the fixing assembly. Next, the second connecting plate 323 in the connector 32 can be connected to the column 33.

[0100] In addition, to enhance the stability of the battery pack on the vibration damping system 2, the present invention can also provide a reinforcing plate between the two vibration damping devices 1. The reinforcing plate is connected to the bearing component 12 in the two vibration damping devices 1 respectively, and the top surface of the reinforcing plate is flush with the bearing surface of the bearing component 12, so that when the battery pack is placed on the vibration damping device 1, the battery pack can contact the top surface of the reinforcing plate.

[0101] It should be noted that the compression of the elastic element 113 under the self-weight load of the battery pack was calculated during the initial design of this utility model. In all embodiments of this utility model, this compression is used as the reference position to make the spring reciprocate up and down. Therefore, in the accompanying drawings of this utility model, the springs in the vibration damping device 1 and the vibration damping system 2 are both in the reference position.

[0102] In addition, the load-bearing component 12 in this invention can also be used to support other objects besides the battery pack, so as to use the shock absorber 11 to achieve buffering and reduce or avoid vibration damage to the object.

[0103] This utility model provides an energy storage container, which may include a container body and any of the vibration damping systems 2 as described above, and the vibration damping system 2 may be installed inside the container body.

[0104] This utility model also provides a mobile energy storage vehicle, which may include a vehicle and an energy storage container as described above, and the vehicle may be used to transport the energy storage container.

[0105] The housing is used to carry the vibration damping system 2, which facilitates the transportation of the vibration damping system 2. When the vehicle encounters vibrations of different levels during operation, the elastic element 113 can reciprocate up and down to absorb and release part of the vertical force of the limiting support 112, thereby reducing the amplitude of the vibration damping device 1. This reduces the risk of strong collisions between the battery pack and the load-bearing components 12 and other structures, thereby reducing the possibility of damage to the battery pack and the vibration damping device 1 and extending the service life of the battery pack and the vibration damping device 1.
