Description

Technical Field

[0001] The present invention relates to the field of intelligent power exchange cabinets, and in particular to a battery compartment for an intelligent power exchange cabinet. Background Art

[0002] With the rapid development of the new energy electric vehicle industry, smart battery swap cabinets are becoming more and more popular in the market as a solution to provide fast and convenient battery charging services. Existing battery swap cabinets usually use traditional battery replacement methods, which poses safety risks and efficiency problems during battery replacement. For example, traditional battery swap cabinets require manual removal of batteries from the cabinet and replacement with new batteries to be charged, which requires a lot of time and labor costs, and there is a risk of battery short circuit or other safety accidents due to improper operation.

[0003] With the development of science and technology, technical personnel in related fields have also carried out a lot of optimization on the battery compartment for smart power exchange cabinets. In order to make a more accurate comparison, a Chinese patent with publication number CN113782886B discloses a battery compartment for a smart power exchange cabinet, including a battery compartment body, a sealing plate, a CT battery plug, an electromagnetic lock mounting plate, a compartment door electromagnetic lock and a push rod, etc.; when in use, the battery block entering the compartment is locked by the battery lock. When the compartment door is opened in an abnormal procedure, the battery lock remains locked to the battery block, and the battery block is not allowed to leave the compartment to prevent the battery block from being stolen. This effectively solves the problem that the battery compartment for existing smart power exchange cabinets is prone to battery block loss and the anti-theft effect is not very good.

[0004] However, the above-mentioned battery compartment for the smart battery swap cabinet still has some shortcomings in actual use: 1. The battery compartment body of the above device is used to place battery packs by forming a cavity through internal hollowing and one of the surfaces is not closed. In the process of placing the battery packs, personnel need to hold the battery packs and lift them to the installation position corresponding to the battery compartment body, and then push them into the cavity of the battery compartment body. Generally speaking, multiple battery compartments are installed in the same smart power exchange cabinet, and the multiple battery compartments are often arranged from bottom to top. Because the installation heights of the multiple battery compartments are different, when they are used for users of different body shapes, different obstacles will be generated accordingly. For example, when a taller person pushes the battery pack into the battery compartments near the lower side, he needs to bend down or squat to hold the battery pack. During use, taller people need to bend over or squat, which may cause their posture to be incorrect. As a result, when aligning and pushing the battery block, the battery block will be skewed in the process of entering the battery compartment, resulting in improper contact between the battery block and the battery compartment, which may easily lead to safety accidents. At the same time, correspondingly, when taller users take out battery blocks at a lower position, since the battery blocks are all inserted in the battery compartment body, it is difficult for the taller users to exert force to take out the battery blocks at the bottom due to the incorrect posture of the users and the limitation of the battery compartment body on the battery blocks.

[0005] 2. The above-mentioned device is connected to a fan and a heater on the battery compartment body, and the temperature of the battery block in the battery compartment body is correspondingly regulated by adjusting the fan and the heater. However, the smart battery exchange cabinet is generally installed outdoors, and multiple battery compartments are installed in the same smart battery exchange cabinet. Therefore, while the smart battery exchange cabinet charges the battery blocks through the above-mentioned battery compartment body, it also needs to provide additional energy for the operation of multiple fans and heaters, which will undoubtedly lead to an increase in economic costs after the deployment of the smart charging cabinet.

[0006] Therefore, based on the above-stated viewpoint, there is still room for improvement in the existing battery compartments for smart battery swap cabinets. Summary of the invention

[0007] In order to solve the above problems, the present invention provides a battery compartment for an intelligent battery exchange cabinet, including a battery exchange cabinet and a plurality of installation cavities formed by an inward depression on one side of the battery exchange cabinet, and battery compartments for placing battery blocks are correspondingly inserted in the installation cavities, and the battery compartment and the power exchange cabinet are connected through a connecting part.

[0008] The battery compartment includes a limiting frame plate connected to the installation cavity and arranged in a U-shaped structure. A supporting frame plate corresponding to the limiting frame plate and arranged in a U-shaped structure is also connected in the same installation cavity. A circuit board is commonly connected to the limiting frame plate and the supporting frame plate at one end away from the compartment door. The circuit board is electrically connected to the limiting frame plate and the supporting frame plate. The limiting frame plate, the supporting frame plate and the circuit board in the same installation cavity cooperate with each other to construct a compartment body for placing battery packs.

[0009] Preferably, the circuit board includes electrode plate 1 connected to the upper limiting frame plate and electrode plate 2 connected to the lower supporting frame plate. Electrode plate 1 and electrode plate 2 extend symmetrically relative to the limiting frame plate and the supporting frame plate to exceed the position height of the limiting frame plate and the supporting frame plate. The extended sections are symmetrically distributed and abut against each other, and electrode plate 1 and electrode plate 2 are electrically connected.

[0010] Preferably, the limit frame plate and the supporting frame plate located in the same installation cavity are commonly connected with a limit end for limiting the supporting frame plate, the limit end includes a sliding cavity symmetrically formed on two vertical sections of the limit frame plate, a plurality of connecting push rods passing through the sliding cavity are symmetrically inserted on the limit frame plate, and the limit strip plate is commonly connected between all the connecting push rods located in the same vertical section of the limit frame plate.

[0011] Preferably, all the connecting push rods on the same limiting frame plate are commonly connected to a bending guide plate inserted on the limiting frame plate.

[0012] Preferably, the connecting push rod is sleeved with a compression spring located between the sliding cavity and the bending guide plate.

[0013] Preferably, the limit frame plate is also symmetrically connected with a limit sleeve passing through the sliding cavity, a connecting slide rod is inserted in the limit sleeve, a clamping strip passing through the limit sleeve is connected to the connecting slide rod, a connecting push block is arranged at the lower end of the connecting slide rod, and a reset compression spring is sleeved on the connecting slide rod and is located between the connecting push block and the limit sleeve.

[0014] Preferably, the limiting sleeve and the electrode plate 1 on the same limiting frame plate are electrically connected.

[0015] Preferably, the connecting portion includes rollers symmetrically connected on the supporting frame plate and limiting slide grooves installed in the power exchange cabinet to limit and guide the rollers.

[0016] Preferably, a limit block for limiting the sliding range of the roller on the supporting frame plate is provided in the limit sliding groove.

[0017] Preferably, a plurality of accommodating cavities with bent structures are formed in the body of the power exchange cabinet corresponding to the positions of the plurality of installation cavities, and a medium is filled in the accommodating cavity for transferring the temperature in the installation cavity.

[0018] In summary, the present application includes at least one of the following beneficial technical effects: 1. The present invention supports the battery pack by means of a supporting frame plate, and limits the path of the battery pack sliding into the battery compartment body by means of the cooperation between the limit frame plate and the supporting frame plate, thereby preventing the battery pack from tilting before sliding into the battery compartment body, improving the stability of the user when sliding the battery pack into the battery compartment body, and thus avoiding safety accidents.

[0019] 2. The present invention creates an effect of vertical misalignment and extension between the limit frame plate and the supporting frame plate in any installation cavity, and then the user places the battery block to be charged between the two vertical sections of the supporting frame plate, and then slides the supporting frame plate and the battery block into the installation cavity together to complete the placement of the battery block. On the contrary, when the battery block needs to be taken out, the user pulls the supporting frame plate and the battery block to slide out a distance at the same time, and again creates an effect of vertical misalignment and extension between the limit frame plate and the supporting frame plate. At this time, since the battery block slides a distance away from the power exchange cabinet, the user can easily lift the battery block out of the battery compartment.

[0020] 3. The present invention forms a plurality of accommodating cavities corresponding to the battery compartments in the battery exchange cabinet. When abnormal charging occurs and the temperature in the battery exchange cabinet rises sharply, the liquid medium in the accommodating cavity is rapidly heated up and vaporized. At the same time, the rising high-temperature water vapor pushes the floating plate and the sliding push frame in the accommodating cavity to move upward and contact the guide block and the extension block, and then drives the supporting frame plate to drive the connected electrode plate 2 to separate from the electrode plate 1, so that the electrode plate 2, the supporting frame plate, the battery socket and the battery block as a whole are quickly powered off, thereby avoiding further losses caused by continued charging of the battery block.

[0021] 4. The present invention uses the high temperature generated when the battery blocks in the battery swap cabinet are abnormally charged to cause the liquid medium in the accommodating cavity to quickly heat up and vaporize, and then absorbs a large amount of heat during the vaporization process of the liquid medium in the accommodating cavity, thereby absorbing and converting the high-temperature heat caused by the abnormal charging of the battery blocks, avoiding the problem of the entire battery swap cabinet being ignited due to the continuous temperature rise, and effectively avoiding the problem of safety accidents that are prone to occur after the battery blocks are abnormally charged.

DETAILED DESCRIPTION

[0034] The following is combined with Figure 1 To Attachment Fig.10 Embodiments of the present invention are described in detail.

[0035] The embodiment of the present application discloses a battery compartment for a smart battery swap cabinet, which explains that the battery compartment for the smart battery swap cabinet is mainly used in the process of placing and removing battery blocks from the battery compartment, and in terms of technical effect, it satisfies the effect that after the user places the battery blocks into the battery compartment for charging, the other battery compartment is released to allow the user to take out the battery blocks therein for replacement; in particular, during use, the sliding cooperation between the limiting frame plate and the supporting frame plate avoids the problem of the user manually adjusting the relative position between the battery blocks and the battery compartment during the replacement of the battery blocks, thereby effectively improving the user experience during use; further, the battery compartment for the smart battery swap cabinet also uses the sliding cooperation between the limiting frame plate and the supporting frame plate, so that users of different body shapes can easily place or remove the battery blocks therein when using it, thereby improving the practicality of the device.

[0036] Example 1: Reference Figure 1 and Figure 2 As shown, a battery compartment for an intelligent power-swap cabinet includes a power-swap cabinet 1, an installation cavity 10, a compartment door 11, a battery compartment 2 and a connection portion 3. The power-swap cabinet 1 has several installation cavities 10 formed by a recess on one side thereof. The power-swap cabinet 1 is also connected with a compartment door 11 corresponding to the several installation cavities 10 and used to close the installation cavities 10. A battery compartment 2 for placing battery blocks is correspondingly inserted in the installation cavity 10. The battery compartment 2 and the power-swap cabinet 1 are connected through a connection portion 3. In the initial state, it is necessary to pre-connect several battery compartments 2 one by one in the installation cavity 10 through the connection portion 3 so as to place the battery blocks later. It should be noted that the power-swap cabinet 1 controls the closing and opening of several cabinet doors through electrical signals. This is a prior art method and will not be described in detail here.

[0037] During use, the battery swap cabinet 1 controls the door 11 of any empty battery compartment 2 to open, and then the user places the used battery block to be charged in the battery compartment 2, and then closes the door 11 to close the battery compartment 2, and charges the battery block placed therein through the battery compartment 2. At the same time, the power swap cabinet 1 also controls the door 11 of any battery compartment 2 containing a fully charged battery block to open, and then the user takes out the fully charged battery block for use, thereby completing the effect of replacing the battery block.

[0038] Reference Figure 2 and Figure 3As shown, it is the battery compartment 2 for placing battery pack blocks. Specifically, the battery compartment 2 includes a limiting frame plate 20 connected in the installation cavity 10 and arranged in a U-shaped structure. In the same installation cavity 10, there is also a supporting frame plate 21 connected corresponding to the limiting frame plate 20 and arranged in a U-shaped structure. At the end of the limiting frame plate 20 and the supporting frame plate 21 away from the door 11, a circuit board 22 is commonly connected. The circuit board 22 is electrically connected between the limiting frame plate 20 and the supporting frame plate 21. Through the mutual cooperation among the limiting frame plate 20, the supporting frame plate 21 and the circuit board 22 in the same installation cavity 10, a cavity for placing battery pack blocks is constructed.

[0039] During use, the battery pack block is supported by the supporting frame plate 21, and the mutual cooperation between the limiting frame plate 20 and the supporting frame plate 21 restricts the path of the battery pack block sliding into the cavity of the battery compartment 2, avoiding the situation of the battery pack block being skewed before sliding into the cavity of the battery compartment 2, improving the stability when the user slides in the battery pack block, and thus avoiding the problem of safety accidents.

[0040] Furthermore, in order to improve the applicability to users of different body types, referring to Figures 2 to 4 As shown, the circuit board 22 includes an electrode plate one 220 connected to the upper limiting frame plate 20 and an electrode plate two 221 connected to the lower supporting frame plate 21. The electrode plate one 220 and the electrode plate two 221 symmetrically extend relative to the limiting frame plate 20 and the supporting frame plate 21 by a section to exceed the position height of the limiting frame plate 20 and the supporting frame plate 21. Their extending sections are symmetrically distributed and can be detachably abutted together. The electrode plate one 220 and the electrode plate two 221 are electrically connected.

[0041] It should be noted that a battery socket is also arranged on the lower supporting frame plate 21. The battery socket on the same supporting frame plate 21 is electrically connected to the electrode plate two 221, and only when the electrode plate one 220 and the electrode plate two 221 in the same installation cavity 10 are mutually attached, the battery socket on the supporting frame plate 21 in this installation cavity 10 will be powered on.

[0042] During use, when a taller user needs to put the battery pack into the battery compartment 2 at a lower height, he first slides the supporting frame plate 21 out of the installation cavity 10 for a distance toward the compartment door 11, so that the limit frame plate 20 and the supporting frame plate 21 in the installation cavity 10 form an effect of vertical dislocation and extension, and while the supporting frame plate 21 moves, it also drives the connected electrode plate 221 to slide synchronously, so that the electrode plate 221 is separated from the contact with the electrode plate 1 220, so as to achieve the effect of cutting off the power to the electrode plate 221, the supporting frame plate 21 and the battery socket as a whole, and then the user places the battery pack to be charged between the two vertical sections of the supporting frame plate 21, and then slides the supporting frame plate 21 and the battery pack into the installation cavity 10 together to complete the placement of the battery pack.

[0043] Similarly, when the battery pack needs to be taken out, one of the compartment doors 11 is controlled to open by the battery exchange cabinet 1, and the user pulls the supporting frame plate 21 and the battery pack to slide out a distance at the same time, so that the limiting frame plate 20 and the supporting frame plate 21 form an upward and downward offset extension effect again. At this time, since the battery pack slides a distance away from the battery exchange cabinet 1, the user can easily lift the battery pack out of the battery compartment 2.

[0044] Furthermore, due to the upper and lower misalignment between the supporting frame plate 21 and the limiting frame plate 20 in the same installation cavity 10, when used for users with relatively weak strength, the user can place one end of the battery block on the supporting frame plate 21 after sliding out in advance, and then adjust the position of the battery block. The sliding supporting frame plate 21 provides certain support for users with relatively weak strength, avoiding the problem that the user needs to lift the battery block to a certain height and then slowly adjust the position of the battery block to align the battery block with the entrance of the battery compartment 2, thereby improving the practicality and applicability of the device.

[0045] In order to improve the protection effect of the battery pack placed in the battery compartment 2, so as to avoid the problem that the battery pack is easily lost after an accident occurs in the power exchange cabinet 1, refer to Figures 3 to 5 As shown, the limit frame plate 20 and the supporting frame plate 21 located in the same installation cavity 10 are commonly connected with a limit end 23 for limiting the supporting frame plate 21, the limit end 23 includes a connecting push rod 230 and a limit strip 231, sliding cavities are symmetrically formed on the two vertical sections of the limit frame plate 20, and a plurality of connecting push rods 230 passing through the sliding cavities are symmetrically inserted on the limit frame plate 20, and the limit strip 231 is commonly connected between all the connecting push rods 230 located in the same vertical section of the limit frame plate 20.

[0046] During use, by moving the connecting push rod 230 downward, the movement of the connecting push rod 230 drives the connected limit strip plate 231 to move downward until the limit strip plate 231 crosses the height position of the extension section of the second electrode plate 221 and then abuts against the supporting frame plate 21. At this time, since the limit strip plate 231 crosses the extension section of the second electrode plate 221, by blocking and limiting the extension section of the second electrode plate 221 by the limit strip plate 231, the position of the supporting frame plate 21 connected to the second electrode plate 221 can be synchronously limited to prevent the supporting frame plate 21 from driving the placed battery pack block to slide out of the installation cavity 10.

[0047] Further, referring to Figures 3 to 5 As shown, a bent guide plate 24 with a U-shaped structure is commonly connected between all the connecting push rods 230 on the same limit frame plate 20. The two horizontal sections of the bent guide plate 24 are simultaneously inserted into the two vertical sections of the limit frame plate 20, and the vertical section of the bent guide plate 24 is arranged on the side close to the compartment door 11 to limit the installed battery pack block.

[0048] During use, after the supporting frame plate 21 and the battery pack block are slid into the installation cavity 10 together, move the bent guide plate 24 downward until the vertical section of the bent guide plate 24 fits against the side of the battery pack block close to the compartment door 11. The movement of the bent guide plate 24 drives the connected connecting push rod 230 to move downward, and the downward movement of the connecting push rod 230 drives the connected limit strip plate 231 to move downward and abut against the supporting frame plate 21. At this time, through the limitation of the battery pack block by the bent guide plate 24 and the limitation of the second electrode plate 221 and the supporting frame plate 21 by the limit strip plate 231, the problem that the supporting frame plate 21 and the placed battery pack block are likely to slide out of the installation cavity 10 after the power supply of the battery swapping cabinet 1 is accidentally cut off can be effectively avoided.

[0049] And in order to facilitate the normal sliding of the supporting frame plate 21 and the placed battery pack block out of the installation cavity 10 and the sliding of the battery pack block to be replaced into the installation cavity 10 when the battery swapping cabinet 1 is normally powered on, referring to Figure 4 and Figure 5 As shown, a compression spring 25 is sleeved on the connecting push rod 230 between the sliding cavity and the bent guide plate 24. During use, after the bent guide plate 24 is moved downward, the downward movement of the bent guide plate 24 causes the connected compression spring 25 to be compressed. After the bent guide plate 24 is moved downward, the compressed compression spring 25 needs to recover and extend, and there is an elastic driving force to always slide upward and reset. After the limitation of the downward-moved bent guide plate 24 is released, the connected bent guide plate 24, connecting push rod 230, and limit strip plate 231 are pushed by the compression spring 25 to slide upward and reset. After the bent guide plate 24, connecting push rod 230, and limit strip plate 231 are reset upward, the limitation of the second electrode plate 221, supporting frame plate 21, and battery pack block is synchronously released, so that the user can normally slide the supporting frame plate 21 and the battery pack block out of the installation cavity 10 and then take out the battery pack block.

[0050] In order to limit the sliding position of the bending guide plate 24 on the limit frame plate 20, refer to Figure 4 and Figure 5 As shown, the limit frame plate 20 is also symmetrically connected with a limit sleeve 26 that passes through the sliding cavity, and a connecting slide rod 260 is inserted in the limit sleeve 26. The connecting slide rod 260 is connected with a clamping strip 261 that passes through the limit sleeve 26, which is used to clamp and limit the bending guide plate 24 in the sliding cavity. A connecting push block 262 is provided at the lower end of the connecting slide rod 260, and a reset compression spring 263 is sleeved on the connecting slide rod 260 and is located between the connecting push block 262 and the limit sleeve 26. It should be noted that the downward elastic force of the reset compression spring 263 is greater than the upward elastic force of the compression spring 25.

[0051] When in use, without external interference, the reset compression spring 263 stretches downward normally to drive the connected connecting slide bar 260 and the connecting push block 262 to move downward, and the connecting slide bar 260 moves downward to drive the connected pressing strip 261 to move downward, so that the pressing strip 261 abuts against the bending guide plate 24 located in the same sliding cavity. After the pressing strip 261 presses against the bending guide plate 24, as the reset compression spring 263 continues to stretch, the connecting slide bar 260 and the connecting push block 262 are moved downward. The rod 230 and the clamping strip 261 move further downward and drive the bending guide plate 24 downward. Since the downward elastic force of the reset compression spring 263 is greater than the upward elastic force of the compression spring 25, the upward movement of the bending guide plate 24 is limited, so that the compression spring 25 is always compressed, thereby making the limiting strip plate 231 and the connecting push block 262 limit the electrode plate 221 and the supporting frame plate 21, and the bending guide plate 24 limits the battery block on the supporting frame plate 21.

[0052] Further, in order to improve the control of the sliding of the supporting frame plate 21 so as to remove the battery pack, refer to Figure 4 and Figure 5 As shown, the limiting sleeve 26 and the electrode plate 220 on the same limiting frame plate 20 are electrically connected, and an electromagnet (not shown in the figure) controlled by the electrode plate 220 is arranged at the upper end of the limiting sleeve 26, and the upper end of the connecting slide rod 260 is also correspondingly arranged to be a metal material that allows the electromagnet (not shown in the figure) to be magnetically attracted.

[0053] When in use, the electromagnet (not shown in the figure) is energized through the electrode plate 1 220. After being energized, the electromagnet (not shown in the figure) generates a magnetic field to magnetically adsorb the connecting slide bar 260, so that the connecting slide bar 260 temporarily overcomes the downward elastic reset force of the reset compression spring 263 and moves upward. The upward movement of the connecting slide bar 260 drives the connected connecting push block 262 and the clamping strip 261 to move upward. The upward movement of the clamping strip 261 releases the clamping limit on the bent guide plate 24 after it moves downward. Therefore, under the upward elastic reset push of the connected compression spring 25, the bending guide plate 24 and the limit strip plate 231 move up and reset until the limit on the electrode plate 221, the supporting frame plate 21 and the battery pack is released.

[0054] At the same time, the connecting push block 262 and the connecting slide rod 260 move upward, driving the connected reset spring 263 to be compressed again, and releasing the limit of the connecting push block 262 on the electrode plate 221. At this time, the overall limit of the electrode plate 221, the supporting frame plate 21 and the battery block are released, so that outsiders can pull the supporting frame plate 21 and the battery block out again, and then complete the effect of taking out the battery block.

[0055] It should be noted that, during normal use, the electromagnet (not shown in the figure) in the limiting sleeve 26 is normally energized through the electrode plate 1 220, so as to attract the connecting slide bar 260 on the limiting sleeve 26 but not completely attract the connecting slide bar 260 to stick to the inner top wall of the limiting sleeve 26, so that the connecting slide bar 260 drives the connected connecting push block 262 to move upward but not completely reset, so as to limit the extension section of the electrode plate 221, so as to avoid the problem that the battery block on the supporting frame plate 21 easily slides out of the installation cavity 10 when charging. At the same time, after charging is completed, the connecting slide bar 260 is further attracted to release the limit at the electrode plate 221, so that the user can take out the charged battery block.

[0056] Reference Figure 6 and Figure 7 As shown, the connection part 3 includes a roller 30 symmetrically connected to the supporting frame plate 21 and a limiting slide groove 31 installed in the power exchange cabinet 1 to limit and guide the roller 30. When in use, the friction between the supporting frame plate 21 and the mounting cavity 10 when sliding in the mounting cavity 10 is effectively reduced through the mutual cooperation of the roller 30 and the limiting slide groove 31, and the response speed of the supporting frame plate 21 when sliding out and into the mounting cavity 10 is improved, thereby achieving the effect of facilitating users to quickly and conveniently complete the replacement of battery packs.

[0057] Reference Figure 6 and Figure 7As shown, a limit stopper 32 for limiting the sliding range of the roller 30 on the supporting frame plate 21 is provided in the limit slide groove 31, and the limit stopper 32 is provided between two rollers 30 located in the same limit slide groove 31. When in use, after the supporting frame plate 21 drives the roller 30 to slide in the direction of sliding out of the installation cavity 10, one of the rollers 30 close to the power exchange cabinet 1 is limited by the limit stopper 32 to prevent the supporting frame plate 21 from sliding out of the installation cavity 10. When the supporting frame plate 21 slides into the power exchange cabinet 1, one of the rollers 30 close to the warehouse door 11 is limited by the limit stopper 32 to prevent the supporting frame plate 21 from driving the connected electrode plate 221 to over-extrude the electrode plate 1 220.

[0058] Reference Figures 7 to 10 As shown, a plurality of accommodating cavities 4 with bent structures are formed in the cabinet body of the power exchange cabinet 1 in correspondence with the positions of the plurality of mounting cavities 10, and a portion of a liquid medium is contained in the accommodating cavity 4, and the medium is preferably a liquid with a high specific heat capacity, and water is used as the working medium in this example. When in use, the heat generated when charging the battery block in the battery compartment 2 is transferred to the mounting cavity 10, and then conducted to the water in the accommodating cavity 4. At this time, due to the high specific heat capacity of water, the heat generated and transferred when the battery block is charged will be absorbed and then converted, effectively avoiding the occurrence of overheating of the battery block during charging.

[0059] Similarly, in a low temperature environment, when using some liquid medium with high specific heat capacity such as water, the high specific heat capacity of water means that it can absorb more heat when reducing the same temperature. Therefore, in a low temperature environment, water can lose heat more slowly, which helps to maintain the temperature in the installation cavity 10, thereby avoiding the problem of slow charging efficiency due to overcooling of the battery pack in a low temperature environment.

[0060] Example 2: Reference Figures 7 to 10 As shown, on the basis of the first embodiment, in order to effectively avoid the problem of safety accidents caused by abnormal charging of the battery blocks when the battery exchange cabinet 1 is charging the battery blocks therein; a floating plate 40 suspended on the medium is also connected in the accommodating cavity 4, and a sliding push frame 41 passing through the accommodating cavity 4 is connected to the floating plate 40, and a guide block 42 pushed by the sliding push frame 41 is connected to the supporting frame plate 21, and the side of the guide block 42 that is resisted by the sliding push frame 41 is set as a sloped structure.

[0061] During use, when the battery pack in the battery compartment 2 is overcharged through the power exchange cabinet 1 and an abnormality occurs, the battery pack in the installation cavity 10 rapidly heats up after charging due to the abnormal charging, and then a higher temperature is generated in the corresponding installation cavity 10 and transmitted to the accommodating cavity 4, causing the medium water in the accommodating cavity 4 to heat up rapidly and gradually vaporize, and then the rising high-temperature water vapor pushes the floating plate 40 suspended in the accommodating cavity 4 to move upward, and the upward movement of the floating plate 40 drives the connected sliding push frame 41 to move upward and connect with the guide block 42. The guide block 42 is touched, and then pushed along the inclined surface of the guide block 42 to slide in the direction away from the electrode plate 1 220. The movement of the guide block 42 drives the connected supporting frame plate 21 to slide. The sliding of the supporting frame plate 21 drives the connected electrode plate 221 to slide synchronously, so that the electrode plate 221 is separated from the electrode plate 1 220, so that the electrode plate 221, the supporting frame plate 21, the battery socket and the battery block are quickly powered off as a whole, thereby avoiding further losses caused by continued charging of the battery block.

[0062] At the same time, a large amount of heat will be absorbed during the vaporization process of the medium water in the corresponding accommodating cavity 4, thereby absorbing and converting the high-temperature heat caused by abnormal charging of the battery block, avoiding the problem of the entire battery swap cabinet 1 being ignited due to the continuous rise in temperature, and effectively avoiding the problem of safety accidents that are prone to occur after abnormal charging of the battery block.

[0063] Furthermore, due to the abnormal charging situation that occurs during the normal charging process of the battery pack, the electromagnet (not shown in the figure) in the limiting sleeve 26 will remain energized during use, thereby continuing to cause the connecting push block 262 to interfere with and limit the electrode plate 221.

[0064] Based on this, the sliding push frame 41 also extends upward for a section, and an extension block 43 pushed by the sliding push frame 41 is also provided on one of the connecting push blocks 262 on the limiting frame plate 20 close to the floating plate 40. During use, the floating plate 40 moves upward to drive the connected sliding push frame 41 to move upward. After the sliding push frame 41 moves upward, its extension section first contacts the extension block 43 upward, and then pushes the extension block 43 and the connecting push block 262 upward. The connecting push block 262 moves upward to drive the connected connecting slide rod 260 to move upward, and drives the connected return compression spring 263 to be completely compressed. In the process of the sliding push frame 41 pushing the extension block 43 and the connecting push block 262 to move upward, the sliding push frame 41 pushes the extension block 43 and the connecting push block 262 upward. The pushing frame 41 also gradually comes into conflict with the inclined surface of the guide block 42. After the connecting push block 262 moves up to release the limit at the electrode plate 221, the sliding push frame 41 pushes the guide block 42, the supporting frame plate 21 and the electrode plate 221 along the inclined surface of the conflicting guide block 42 to slide away from the electrode plate 1 220, so that the electrode plate 221 is separated from the electrode plate 1 220, and at the same time, the supporting frame plate 21, the battery socket and the battery pack are completely powered off.

[0065] During operation: The first step is that the user controls the battery exchange cabinet 1 to open the door 11 of any empty battery compartment 2, and then slides the supporting frame plate 21 out of the installation cavity 10, and then places the battery pack to be replaced and charged on the supporting frame plate 21 and pushes it into the installation cavity 10 to reset it, and then closes the door 11.

[0066] Step 2: After the user places the battery pack into the battery compartment 2 and closes the compartment door 11, the power exchange cabinet 1 controls the compartment door 11 of any battery compartment 2 containing a fully charged battery pack to open, and simultaneously releases the limit of the battery pack and the supporting frame plate 21, and then the user can take out the battery pack.

Therefore, the embodiments should be considered as exemplary and non-restrictive in all respects.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
