[0002] Since the air conditioner needs to exchange heat with the external atmospheric environment, the air inlet and outlet of the air conditioner must be exposed outside the battery cabinet. In the related art, a rubber sealing strip is often used in conjunction with a cabinet lock or bolts to achieve the seal between the air conditioner and the battery cabinet. The sealing principle is: the compression force generated by tightening the bolts or locking the cabinet locks is used to compress the sealing strip to deform, and the resilience of the sealing strip enables the sealing strip to be tightly clamped between the cabinet door and the air conditioner to achieve the seal between the cabinet door and the air conditioner. However, each sealing point between the cabinet door and the air conditioner needs to be provided with a bolt or cabinet lock to cooperate with the sealing strip. When the air conditioner needs to be maintained, the bolts or door locks need to be removed, which makes the maintenance operation of the air conditioner difficult. Utility Model Content

DETAILED DESCRIPTION

[0037] Reference below Figure 1-Figure 8 An energy storage device 100 according to an embodiment of the present invention is described.

[0038] like Figure 1-Figure 8 As shown, the energy storage device 100 according to the embodiment of the utility model includes a battery 2, a cabinet 1, an air conditioner 3 and a magnetic seal 4.

[0039] Specifically, the cabinet 1 includes a cabinet body 11 and a cabinet door 12. One side of the cabinet body 11 is open, for example, one side in the thickness direction of the cabinet body 11 is open. The cabinet door 12 is arranged on the open side of the cabinet body 11. The cabinet body 11 and the cabinet door 12 jointly define a receiving cavity 13. The receiving cavity 13 receives the battery 2. An opening 122 is formed on the cabinet door 12. The air conditioner 3 is arranged in the receiving cavity 13, and the air conditioner 3 is arranged opposite to the opening 122. The magnetic seal 4 is arranged around the periphery of the opening 122 to seal the gap between the cabinet door 12 and the air conditioner 3. The magnetic seal 4 is located at the opening 122.

[0040] For example, in Figure 1 and Figure 2In the example, the air conditioner 3 is arranged in the accommodating cavity 13, so that the cabinet 1 is used to protect the air conditioner 3, and the dynamic water flow is prevented from contacting the air conditioner 3 and causing corrosion or damage to the air conditioner 3. The magnetic seal 4 is arranged on the circumference of the air conditioner 3, and the gap between the air conditioner 3 and the cabinet door 12 is filled by the magnetic seal 4, so as to further prevent the water outside the cabinet 1 from entering the air conditioner 3 along the gap between the air conditioner 3 and the cabinet door 12, that is, the waterproof property of the air conditioner 3 is further improved, thereby improving the operating stability of the air conditioner 3 and extending the service life of the air conditioner 3.

[0041] During actual use, one end of the magnetic seal 4 can be connected to the cabinet 1 by bonding, and the magnetic seal 4 can be arranged along the circumference of the opening 122, and the other end of the magnetic seal 4 can be connected to the air conditioner 3 by magnetic attraction, thereby realizing the installation of the magnetic seal 4 between the air conditioner 3 and the cabinet door 12, while meeting the waterproof and sealing requirements of the air conditioner 3, simplifying the connection method between the magnetic seal 4 and the air conditioner 3.

[0042] Along the height direction of the cabinet 1 (for example, Figure 1 In the up and down direction), the air conditioner 3 is arranged at the upper part of the accommodating cavity 13, and the battery 2 is arranged at the lower part of the accommodating cavity 13, so as to reduce the distance between the air conditioner 3 and the battery 2, thereby reducing the length of the wiring harness arranged in the accommodating cavity 13, reducing the risk of mutual interference between the wiring harnesses, and also avoiding the generation of static electricity in the wiring harness during use, thereby improving the safety of the use of the air conditioner 3 and the battery 2.

[0043] Among them, the cabinet door 12 can move between an open position for opening the open side of the cabinet body 11 and a closed position for closing the open side of the cabinet body 11, that is, the cabinet door 12 is rotatably connected to the cabinet body 11. When the cabinet door 12 is in the open position, the open side of the cabinet body 11 is in an open state, so that it is convenient to install the air conditioner 3 and the battery 2 in the accommodating cavity 13, or to perform inspection and maintenance operations on the air conditioner 3 and the battery 2. When the cabinet door 12 is in the closed position, the open side of the cabinet body 11 is blocked by the cabinet door 12, and the cabinet door 12 can effectively block the air conditioner 3 and the battery 2, thereby improving the waterproofness of the air conditioner 3 and the battery 2. When the cabinet door 12 is switched between the open position and the closed position, the magnetic seal 4 can avoid damage to the surface of the cabinet door 12 and the air conditioner 3, thereby improving the use stability of the magnetic seal 4, the cabinet door 12 and the air conditioner 3.

[0044] According to the energy storage device 100 of the embodiment of the utility model, a magnetic seal 4 is arranged between the air conditioner 3 and the cabinet door 12, and the gap between the air conditioner 3 and the cabinet door 12 is filled with the magnetic seal 4, so as to prevent water outside the cabinet 1 from entering the air conditioner 3 along the gap between the air conditioner 3 and the cabinet 1, thereby improving the waterproofness of the air conditioner 3, and the connection method between the magnetic seal 4 and the air conditioner 3 is simple and easy to operate.

[0045] According to some embodiments of the present invention, referring to Figure 1-Figure 4 , combined with Figure 8 , an air conditioning flange 31 is provided on the air conditioner 3. When the cabinet door 12 is in the closed position, the side surface of the cabinet door 12 facing the air conditioning flange 31 and the air conditioning flange 31 are sealed by the magnetic seal 4. The air conditioning flange 31 is provided on the outer peripheral surface of the air conditioner 3, and the air conditioning flange 31 extends in a direction away from the air conditioner 3. Therefore, when the magnetic seal 4 is sealed between the cabinet door 12 and the air conditioning flange 31, the magnetic seal 4 can be clamped between the cabinet door 12 and the air conditioning flange 31, thereby ensuring the sealing between the cabinet door 12 and the air conditioner 3.

[0046] According to some embodiments of the present invention, referring to Figure 1-Figure 4 , combined with Figure 6 and Figure 7 , the side wall of the cabinet door 12 facing the air conditioner 3 is the first side wall 121, the magnetic seal 4 includes an elastic member 41 and a first magnetic member 42, one end of the elastic member 41 is connected to the first side wall 121, and the first magnetic member 42 is arranged at the other end of the elastic member 41, and when the cabinet door 12 is in the closed position, the first magnetic member 42 is adsorbed with the air conditioner flange 31. The end of the elastic member 41 away from the first magnetic member 42 is connected to the side surface of the cabinet door 12 facing the air conditioner flange 31 to position the magnetic seal 4, that is, the magnetic seal 4 is fixed on the cabinet door 12 to prevent the magnetic seal 4 from moving during use, thereby improving the stability of the magnetic seal 4 on the cabinet door 12, and thus improving the use stability of the magnetic seal 4. The other end of the elastic member 41 provided with the first magnetic member 42 is connected to the air conditioner flange 31 by magnetic attraction, so that the magnetic seal 4 can be sealed between the cabinet door 12 and the air conditioner flange 31.

[0047] When the cabinet door 12 is in the closed position, the first magnetic member 42 is attracted to the air conditioning flange 31, thereby ensuring the sealing between the cabinet door 12 and the air conditioner 3. When the cabinet door 12 is switched from the closed position to the open position, the first magnetic member 42 is separated from the air conditioning flange 31, so that the cabinet body 11 is in the open state, which is convenient for the inspection and maintenance of the air conditioner 3.

[0048] According to other embodiments of the utility model, one end of the elastic member 41 is connected to a side surface of the air-conditioning flange 31 facing the first side wall 121, and the first magnetic member 42 is arranged at the other end of the elastic member 41. When the cabinet door 12 is in the closed position, the first magnetic member 42 is adsorbed on the air-conditioning flange 31. The end of the elastic member 41 away from the first magnetic member 42 is connected to a side surface of the air-conditioning flange 31, that is, the magnetic seal 4 is fixed on the air-conditioning flange 31, so as to prevent the magnetic seal 4 from moving during use, improve the stability of the magnetic seal 4 on the air-conditioning flange 31, and thus improve the use stability of the magnetic seal 4. The other end of the elastic member 41 provided with the first magnetic member 42 is connected to the first side wall 121 by magnetic attraction, so that the magnetic seal 4 can be sealed between the cabinet door 12 and the air-conditioning flange 31.

[0049] Optionally, the magnetic seal 4 is an annular seal, and the magnetic seal 4 is arranged circumferentially around the opening 122 so that the magnetic seal 4 completely fills the gap between the cabinet door 12 and the air conditioner 3 to meet the waterproof and sealing requirements of the air conditioner 3.

[0050] Optionally, refer to Figure 6 and Figure 7 The elastic member 41 is a hollow structure, which is beneficial to increase the elasticity of the elastic member 41. The first magnetic member 42 is arranged in the elastic member 41, which protects the first magnetic member 42 and prevents the elastic member 41 from being damaged, thereby ensuring the connection reliability between the magnetic seal 42 and the air conditioning flange 31.

[0051] According to some embodiments of the present invention, a plurality of folds 421 are provided on the elastic member 41, and the elastic member 41 is provided between the first side wall 121 and the air conditioning flange 31 (for example, Figure 6 In the description of the present utility model, "multiple" means two or more. Figure 6 and Figure 7 As shown, six pleated portions 421 are formed on the elastic member 41, and three of the six pleated portions 421 are arranged in the width direction of the elastic member 41 (for example, Figure 6 The other three of the six pleated portions 421 are arranged on the other side of the width direction of the elastic member 41. Thus, the elasticity of the elastic member 41 is increased, so that the elastic member 41 can fully fill the gap between the air conditioner 3 and the cabinet door 12, and further improve the installation stability of the magnetic seal 4 between the cabinet 1 and the air conditioner 3. At the same time, the arrangement of the pleated portion 421 enables the elastic member 41 to fully compress or restore the deformation.

[0052] Optionally, the air conditioning flange 31 is a second magnetic component. For example, the air conditioning flange 31 can be made of magnetic steel material to cooperate with the magnetic seal 4 to generate magnetic force so that the magnetic seal 4 can be stably adsorbed on the air conditioning flange 31.

[0053] According to some embodiments of the present invention, referring to Figure 1-Figure 3 Combined with Figure 5 A portion of the air conditioner 3 extends out of the opening 122, and an air inlet and an air outlet are formed on the air conditioner 3. The air inlet and the air outlet are arranged along the height direction of the air conditioner 3, and the air inlet and the air outlet are opposite to the opening 122, so that the air inlet and the air outlet of the air conditioner 3 are exposed.

[0054] A second side wall 123 is provided at the opening 122, and the second side wall 123 is located on the side of the first side wall 121 away from the air conditioning flange 31. The energy storage device 100 also includes a first seal 5, which is provided between the second side wall 123 and the air conditioner 3. The first seal 5 can block the jet water flow to prevent the jet water flow from impacting the magnetic seal 4, thereby protecting the magnetic seal 4. The size of the opening 122 is suitable for the size of the side of the air conditioner 3 facing the cabinet door 12, so that the first seal 5 is installed between the second side wall 123 and the air conditioner 3, thereby improving the sealing between the second side wall 123 and the air conditioner 3.

[0055] During use, the magnetic seal 4 and the first seal 5 form two layers of sealing protection to ensure the sealing and waterproofness of the air conditioner 3. The first seal 5 acts as the first waterproof layer to prevent the jet water flow from directly scouring the magnetic seal 4, effectively alleviating the pressure of the jet water flow. The first seal 5 can be an annular seal, which is beneficial to increase the completeness of the seal between the second side wall 123 and the air conditioner 3. The magnetic seal 4 acts as the second waterproof layer to prevent moisture and dust from entering the air conditioner 3 and prevent the water flow without water pressure after passing through the first waterproof layer from penetrating into the air conditioner 3. In other words, the force acting on the air conditioner 3 is the sum of the magnetic attraction force generated by the magnetic seal 4 and the compression resilience of the first seal 5, thereby achieving reliable sealing of the air conditioner 3.

[0056] Further, refer to Figure 3 and Figure 4The energy storage device 100 further includes an extension portion 124, one end of which is connected to the first side wall 121, and one end of which is connected to the second side wall 123. Along the extension direction of the extension portion 124, the first side wall 121 and the second side wall 123 are spaced apart. At this time, the second side wall 123 and the extension portion 124 are L-shaped. The extension portion 124 is used to separate the first side wall 121 and the second side wall 123 from the surface of the air conditioner 3. The first sealing member 5 is used to fill the gap between the second side wall 123 and the air conditioner 3 to further increase the sealing and waterproof properties between the cabinet door 12 and the air conditioner 3. The cooperation between the extension portion 124 and the second side wall 123 is conducive to reducing the weight of the cabinet door 12, thereby improving the installation stability of the cabinet door 12 on the open side of the cabinet body 11.

[0057] According to some embodiments of the utility model, the first sealing member 5 is a foam sealing strip. The foam sealing strip has the advantages of low water absorption, good elasticity, good resistance to compression deformation, excellent aging resistance and excellent flame retardant performance. Using the foam sealing strip as the first sealing member 5 is conducive to increasing the sealing and waterproof properties between the cabinet door 12 and the air conditioner 3.

[0058] According to some embodiments of the present invention, the energy storage device 100 further includes a second sealing member 6, which is suitable for sealing between the edge of the cabinet door 12 and the cabinet body 11. Figure 1 and Figure 2 Combined with Figure 3 and Figure 5 A second seal 6 is provided between the cabinet door 12 and the cabinet body 11. The second seal 6 can be an annular seal to seal the cabinet door 12 and the cabinet body 11 to prevent water from entering the accommodating cavity 13 from the gap between the cabinet door 12 and the cabinet body 11, thereby improving the safety of the air conditioner 3 and the battery 2. At the same time, the second seal 6 can also prevent the jet water from scouring the magnetic seal 4 to improve the service life of the magnetic seal 4.

[0059] When the cabinet door 12 is in the closed position, the cabinet door 12 and the cabinet body 11 can be locked by using a locking device such as a connecting rod lock. The locking pressure generated by the locking device compresses the second sealing member 6 so that the second sealing member 6 is stably installed between the cabinet door 12 and the cabinet body 11, thereby improving the sealing stability between the cabinet door 12 and the cabinet body 11.

[0060] Furthermore, the compression stroke of the magnetic seal 4 is greater than the compression stroke of the second seal 6. Therefore, when the second seal 6 between the cabinet door 12 and the cabinet body 11 is compressed, the magnetic seal 4 between the cabinet door 12 and the air conditioner 3 is also reliably compressed to form a reliable seal between the cabinet body 1 and the air conditioner 3.

[0061] According to some embodiments of the utility model, the stiffness of the magnetic seal 4 is less than the stiffness of the second seal 6. Among them, stiffness refers to the ability of a material or structure to resist elastic deformation when subjected to force, and stiffness is a representation of the ease of elastic deformation of a material or structure, that is, under the same load, the greater the stiffness, the smaller the deformation. The stiffness of the magnetic seal 4 is made smaller, and the deformation of the magnetic seal 4 is effectively avoided, thereby improving the structural strength of the magnetic seal 4 and extending the service life of the magnetic seal 4. Among them, the magnetic force of the first magnetic component 42 of the magnetic seal 4 compensates for the problem of the smaller rebound force of the magnetic seal 4, so that the magnetic seal 4 can be stably arranged between the cabinet door 12 and the air conditioner 3.

[0062] The second seal 6 has a relatively small rigidity. When the cabinet door 12 is in the closed position, the second seal 6 can fully fill the gap between the edge of the cabinet door 12 and the cabinet body 11 , thereby facilitating improving the sealing between the edge of the cabinet door 12 and the cabinet body 11 .

[0063] Specifically, the rigidity of the magnetic seal 4 is smaller than that of the second seal 6, and the compression stroke of the magnetic seal 4 is greater than that of the second seal 6. When the second seal 6 between the cabinet door 12 and the cabinet body 11 is compressed, the magnetic seal 4 between the cabinet door 12 and the air conditioner 3 is also reliably compressed, so as to form a reliable seal between the cabinet door 12 and the air conditioner 3 by pressure plus magnetic force.

[0064] In addition, at least one of the first seal 5 and the second seal 6 is an annular seal. That is, only the first seal 5 can be an annular seal; or only the second seal 6 can be an annular seal; or both the first seal 5 and the second seal 6 can be annular seals, so as to improve the sealing performance of the energy storage device 100.

[0065] According to some embodiments of the present invention, the second sealing member 6 is a rubber sealing strip. The rubber sealing strip has the advantages of good heat preservation, low water absorption, buffering, temperature resistance and sound absorption. The use of the rubber sealing strip as the second sealing member 6 is conducive to improving the sealing and waterproof properties between the cabinet door 12 and the cabinet body 11, while reducing the cost of the second sealing member 6.

[0066] The energy storage system (not shown) according to the second embodiment of the utility model includes a plurality of energy storage devices 100, which are electrically connected to each other. The energy storage devices 100 are the energy storage devices 100 according to the first embodiment of the utility model.

[0067] According to the energy storage system of the embodiment of the present utility model, by adopting the above-mentioned energy storage device 100, the waterproofness of the energy storage system can be improved, thereby increasing the service life of the energy storage system.
