Description

Technical Field

[0001] The present application belongs to the technical field of charging equipment, and specifically relates to a battery swap cabinet. Background Art

[0002] The battery swap cabinet is used to charge the battery of electric vehicles, which is the infrastructure of electric vehicle energy services. At present, with the popularization of electric vehicles, higher requirements are placed on the durability of the battery swap cabinet.

[0003] Traditional power exchange cabinets usually include a cabinet body, which has a battery compartment, and the inner cavity of the battery compartment is used to accommodate batteries. During specific use, when charging the battery, the battery itself and the electronic components in the inner cavity of the battery compartment used to power the battery will emit heat. At present, this heat is simply dissipated by natural heat dissipation, which is slow. Heat is easily accumulated in the inner cavity of the battery compartment, which easily leads to a high temperature in the inner cavity of the battery compartment. When the temperature of the inner cavity of the battery compartment is high, the electronic components in the inner cavity of the battery compartment are easily damaged, resulting in poor durability of the power exchange cabinet. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide a battery swap cabinet that can solve the problem of poor durability of the battery swap cabinet in the related art.

[0005] The present application provides a power exchange cabinet, including:

[0006] A cabinet, wherein the cabinet has a heat exchange compartment and a battery compartment, and the heat exchange compartment is connected to the outside;

[0007] A liquid storage container, a first heat exchanger, a second heat exchanger and a pressurizing device, wherein the liquid storage container is used to store heat exchange liquid, the first heat exchanger is arranged in the battery compartment, the second heat exchanger is arranged in the inner cavity of the heat exchange compartment, the liquid outlet of the liquid storage container, the first heat exchanger, the second heat exchanger and the liquid inlet of the liquid storage container are sequentially connected, and a liquid delivery circuit for delivering the heat exchange liquid is formed, the pressurizing device is arranged on the liquid delivery circuit, and is used to drive the heat exchange liquid to circulate in the liquid delivery circuit, and the heat exchange liquid flows from the first heat exchanger to the second heat exchanger;

[0008] An air extraction component is connected to the heat exchange chamber and is used to extract external air into the heat exchange chamber.

[0009] In the embodiment of the present application, the first heat exchanger is arranged in the battery compartment, the second heat exchanger is arranged in the inner cavity of the heat exchange compartment, the liquid outlet of the liquid storage container, the first heat exchanger, the second heat exchanger and the liquid inlet of the liquid storage container are connected in sequence, and a liquid delivery circuit for delivering heat exchange liquid is formed, the pressurizing device is arranged on the liquid delivery circuit, and is used to drive the heat exchange liquid to circulate in the liquid delivery circuit, and the heat exchange liquid flows from the first heat exchanger to the second heat exchanger, and the air extraction part is connected to the heat exchange compartment and is used to draw outside air into the heat exchange compartment. In this arrangement, when the heat exchange liquid flows through the first heat exchanger, the heat exchange liquid exchanges heat with the battery compartment. At this time, the heat exchange liquid can absorb at least part of the heat of the battery compartment, thereby reducing the temperature of the battery compartment. Afterwards, when the heat exchange liquid flows through the second heat exchanger, the heat exchange liquid can exchange heat with the outside air, thereby dissipating at least part of the heat absorbed by it. It can be seen that in the embodiment of the present application, the first heat exchanger and the second heat exchanger can export at least part of the heat from the battery compartment. In this way, the battery compartment of the power swap cabinet provided in the embodiment of the present application can not only dissipate heat naturally, but also rely on the first heat exchanger and the second heat exchanger for heat dissipation, thereby making the heat dissipation efficiency of the battery compartment higher. In this way, the probability of electronic components in the inner cavity of the battery compartment being damaged by temperature is lower, thereby making the durability of the power swap cabinet better.

Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0026] The following is a detailed description of the power exchange cabinet provided in the embodiment of the present application through specific embodiments and their application scenarios in combination with the accompanying drawings.

[0027] Please refer to Figures 1 to 5 As shown, an embodiment of the present application provides a power exchange cabinet, including: a cabinet body 100, a liquid storage container 210, a first heat exchanger 220, a second heat exchanger 230, a pressurizing device 240 and an exhaust component 250.

[0028] Specifically, the cabinet 100 has a heat exchange chamber 110 and a battery chamber 120 , and the heat exchange chamber 110 is connected to the outside. More specifically, the cabinet 100 is provided with air holes, for example, and the heat exchange chamber 110 is connected to the outside through the air holes.

[0029] The liquid storage container 210 is used to store heat exchange liquid, the first heat exchanger 220 is arranged in the battery compartment 120, and the second heat exchanger 230 is arranged in the inner cavity of the heat exchange compartment 110. The liquid outlet of the liquid storage container 210, the first heat exchanger 220, the second heat exchanger 230 and the liquid inlet of the liquid storage container 210 are connected in sequence, and a liquid delivery circuit 300 for delivering heat exchange liquid is formed. The pressurizing device 240 is arranged on the liquid delivery circuit 300, and is used to drive the heat exchange liquid to circulate in the liquid delivery circuit 300. The pressurizing device 240 is, for example, a water pump, and the heat exchange liquid flows from the first heat exchanger 220 to the second heat exchanger 230. Specifically, the heat exchange liquid, for example, flows through the liquid outlet of the liquid storage container 210, the first heat exchanger 220, the second heat exchanger 230 and the liquid inlet of the liquid storage container 210 in sequence.

[0030] The air extraction component 250 is in communication with the heat exchange chamber 110 and is used to extract external air into the heat exchange chamber 110 . The air extraction component 250 is, for example, a fan or an air pump.

[0031] In the embodiment of the present application, the first heat exchanger 220 is arranged in the battery compartment 120, the second heat exchanger 230 is arranged in the inner cavity of the heat exchange compartment 110, the liquid outlet of the liquid storage container 210, the first heat exchanger 220, the second heat exchanger 230 and the liquid inlet of the liquid storage container 210 are connected in sequence, and a liquid delivery circuit 300 for delivering heat exchange liquid is formed. The pressurizing device 240 is arranged on the liquid delivery circuit 300, and is used to drive the heat exchange liquid to circulate in the liquid delivery circuit 300, and the heat exchange liquid flows from the first heat exchanger 220 to the second heat exchanger 230, and the exhaust component 250 is connected to the heat exchange compartment 110, and is used to draw outside air into the heat exchange compartment 110. With such a configuration, when the heat exchange liquid flows through the first heat exchanger 220, the heat exchange liquid exchanges heat with the battery compartment 120. At this time, the heat exchange liquid can absorb at least part of the heat of the battery compartment 120, thereby reducing the temperature of the battery compartment 120. Afterwards, when the heat exchange liquid flows through the second heat exchanger 230, the heat exchange liquid can exchange heat with the outside air, thereby dissipating at least part of the heat absorbed by it. It can be seen that in the embodiment of the present application, the first heat exchanger 220 and the second heat exchanger 230 can export at least part of the heat of the battery compartment 120. In this way, the battery compartment 120 of the power exchange cabinet provided in the embodiment of the present application can rely on the first heat exchanger 220 and the second heat exchanger 230 for heat dissipation in addition to natural heat dissipation, thereby making the heat dissipation efficiency of the battery compartment 120 higher. In this way, the probability of electronic components in the inner cavity of the battery compartment 120 being damaged by temperature is lower, thereby making the durability of the power exchange cabinet better.

[0032] In addition, when the temperature of the battery compartment 120 is lower than the temperature of the heat exchange liquid, after the heat exchange liquid and the battery compartment 120 perform heat exchange, the battery compartment 120 can absorb at least part of the heat of the heat exchange liquid, thereby increasing the temperature of the battery compartment 120. It should be noted that a higher or lower temperature of the battery compartment 120 will affect the charging of the battery, so when the temperature of the battery compartment 120 is high, the battery compartment 120 needs to be cooled down, and conversely, when the temperature of the battery compartment 120 is low, the battery compartment 120 needs to be heated up.

[0033] In addition, when the temperature of the heat exchange liquid is lower than the temperature of the outside air, after the heat exchange liquid exchanges heat with the outside air, the heat exchange liquid can absorb at least part of the heat of the outside air, thereby increasing the temperature of the heat exchange liquid.

[0034] As a specific implementation manner, the first heat exchanger 220 and the second heat exchanger 230 are, for example, radiators, and the heat exchange liquid is, for example, water.

[0035] In another embodiment, reference Figure 2 As shown, the power exchange cabinet also includes a liquid delivery branch 400, a first control valve 260 and a second control valve 270. The liquid delivery circuit 300 includes a first branch 310. The second heat exchanger 230 is arranged on the first branch 310. In other words, the second heat exchanger 230 is connected in series to the first branch 310, and the heat exchange liquid flows through the first branch 310 and the second heat exchanger 230 at the same time.

[0036] The first branch 310 is arranged in parallel with the liquid delivery branch 400, and the two ends of the first branch 310 in its own extension direction and the two ends of the liquid delivery branch 400 in its own extension direction are respectively connected to the first heat exchanger 220 and the liquid inlet of the liquid storage container 210, that is, one of the two ends of the first branch 310 in its own extension direction is connected to the first heat exchanger 220, and the other is connected to the liquid inlet of the liquid storage container 210, and at the same time, one of the two ends of the liquid delivery branch 400 in its own extension direction is connected to the first heat exchanger 220, and the other is connected to the liquid inlet of the liquid storage container 210.

[0037] The first control valve 260 is provided at the first branch 310 and is used to control the on-off of the first branch 310. The second control valve 270 is provided at the liquid delivery branch 400 and is used to control the on-off of the liquid delivery branch 400. Specifically, the first control valve 260 and the second control valve 270 are both solenoid valves, for example. When the first control valve 260 is in an open state, the first branch 310 is in a conducting state, at which time the heat exchange liquid can flow back to the liquid storage container 210 along the first branch 310. When the first control valve 260 is in a closed state, the first branch 310 is in a cut-off state, and the heat exchange liquid cannot flow through the first branch 310. Similarly, when the second control valve 270 is in an open state, the liquid delivery branch 400 is in a conducting state, at which time the heat exchange liquid can flow back to the liquid storage container 210 along the liquid delivery branch 400. When the second control valve 270 is in a closed state, the liquid delivery branch 400 is in a cut-off state, and the heat exchange liquid cannot flow through the liquid delivery branch 400.

[0038] During specific use, when the temperature of the battery compartment 120 is higher than the preset temperature, for example, the temperature of the heat exchange liquid is lower than the temperature of the battery compartment 120, and for example, the first control valve 260 is opened and the second control valve 270 is closed, so that the heat exchange liquid mainly flows back to the liquid storage container 210 through the first branch 310. Since the heat exchange liquid will inevitably flow through the second heat exchanger 230 when flowing through the first branch 310, the heat exchange liquid can exchange heat with the outside air, and the heat exchange liquid can dissipate at least part of the heat absorbed by it. When the temperature of the battery compartment 120 is lower than the preset temperature, for example, the temperature of the heat exchange liquid is higher than the temperature of the battery compartment 120, and for example, the first control valve 260 is closed, and the second control valve 270 is opened, so that the heat exchange liquid mainly flows back to the liquid storage container 210 through the liquid delivery branch 400. In this case, the first branch 310 is in a cut-off state, and the heat exchange liquid cannot flow through the first branch 310, so that it cannot continuously exchange heat with the second heat exchanger 230. In this way, the heat exchange between the heat exchange liquid and the outside air can be reduced, thereby reducing the heat loss of the heat exchange liquid. It can be seen that in this embodiment, by controlling the opening and closing of the first control valve 260 and the second control valve 270, the heat absorbed by the heat exchange liquid can be dissipated, and the heat exchange between the heat exchange liquid and the outside air can be reduced, so that the solution adopted in this embodiment can better meet the heat exchange requirements of the battery compartment 120.

[0039] In other optional embodiments, the power exchange cabinet may not include the liquid delivery branch 400 and the second control valve 270 mentioned above.

[0040] In another embodiment, reference Figure 1 and Figure 2As shown, the cabinet 100 also includes an electrical compartment 130, which is independent of the heat exchange compartment 110 and the battery compartment 120. Optionally, any two of the electrical compartment 130, the heat exchange compartment 110 and the battery compartment 120 are independent. The power exchange cabinet also includes an electronic component 500, a third heat exchanger 280 and a gas drive mechanism 290. The electronic component 500, the third heat exchanger 280 and the gas drive mechanism 290 are all arranged in the electrical compartment 130. The third heat exchanger 280 is arranged in the liquid delivery circuit 300 and is located between the liquid outlet of the liquid storage container 210 and the second heat exchanger 230. The gas drive mechanism 290 is used to drive the gas in the inner cavity of the electrical compartment 130 to circulate in the inner cavity of the electrical compartment 130, so that the third heat exchanger 280 can exchange heat with the gas in the inner cavity of the electrical compartment 130 more quickly. The gas drive mechanism 290 is, for example, a fan. With such a configuration, when the heat exchange liquid flows through the third heat exchanger 280, the heat exchange liquid can exchange heat with the gas in the inner cavity of the electrical compartment 130, thereby adjusting the temperature of the inner cavity of the electrical compartment 130, thereby preventing the temperature of the inner cavity of the electrical compartment 130 from being too high or too low, thereby extending the service life of the electronic components 500 in the inner cavity of the electrical compartment 130.

[0041] As a specific implementation, the third heat exchanger 280 is, for example, a radiator.

[0042] In other optional embodiments, the power exchange cabinet may not include the third heat exchanger 280 and the gas drive mechanism 290.

[0043] In a further embodiment, the electrical compartment 130 is, for example, a closed structure, so that the electrical compartment 130 has better sealing performance, thereby making the electrical compartment 130 have a higher protection level, thereby making the service life of the electronic components 500 in the inner cavity of the electrical compartment 130 longer.

[0044] In other optional embodiments, the electrical compartment 130 may also be a non-enclosed structure.

[0045] In another embodiment, the power exchange cabinet may further include a fire branch and a fire sprinkler 600. The fire branch is independent of the liquid delivery circuit 300. The fire branch is used to deliver liquid for fire extinguishing. The liquid for fire extinguishing is, for example, water. The fire sprinkler 600 is, for example, disposed in the inner cavity of the battery compartment 120, and the fire sprinkler 600 is, for example, connected to the fire branch.

[0046] In other optional embodiments, the fire sprinkler 600 may also be directly connected to the first heat exchanger 220. Compared with the power exchange cabinet provided in the previous embodiment, the power exchange cabinet provided in this embodiment at least omits the fire branch, so that the power exchange cabinet provided in this embodiment has a simpler structure and lower cost.

[0047] During specific use, when the electronic components in the inner cavity of the battery compartment 120 catch fire, the fire sprinkler 600 can be automatically opened. At this time, the heat exchange liquid can be sprayed out from the fire sprinkler 600, so as to extinguish the burning electronic components.

[0048] In another embodiment, reference Figure 1 and Figure 5 As shown, the battery exchange cabinet also includes a charging component and a DC conversion module 520. The charging component is, for example, a charging cable. The electronic component 500 includes: a power distribution module and an AC-to-DC module 510. The power distribution module, the AC-to-DC module 510, the DC conversion module 520 and the charging component are electrically connected in sequence. The charging component and the DC conversion module 520 are, for example, both arranged in the inner cavity of the battery compartment 120. The battery compartment 120 is, for example, provided with heat dissipation holes. The DC conversion module 520 dissipates more heat when working. By providing the heat dissipation holes, the heat in the inner cavity of the battery compartment 120 can be dissipated, thereby preventing the temperature of the inner cavity of the battery compartment 120 from being too high.

[0049] In other optional embodiments, the DC conversion module 520 may also be disposed in the inner cavity of the electrical compartment 130. In this case, the electronic component 500 described above, for example, includes the DC conversion module 520 in this embodiment, and the battery compartment 120, for example, does not have the heat dissipation holes described above. In this embodiment, the battery compartment 120 is not provided with heat dissipation holes, so that the sealing of the battery compartment 120 is better, and thus the protection level of the battery compartment 120 is higher. In addition, with such a configuration, electronic components with high heat generation, such as the power distribution module, the AC-to-DC module 510, and the DC conversion module 520, are uniformly disposed in the inner cavity of the electrical compartment 130. In this way, it is convenient to manage the heat of the heat exchange cabinet, and the heat exchange cabinet can be heated or cooled more conveniently and quickly.

[0050] During specific use, the power distribution module receives AC power input from an external power source and transmits the AC power to the AC-DC module 510. The AC-DC module 510 then converts the AC power into DC power and transmits the converted DC power to the DC conversion module 520. The DC conversion module 520 then adjusts the voltage of the DC power to the preset voltage required for battery charging and charges the battery through the charging component.

[0051] As a specific implementation, the power distribution module, the AC-DC module 510 and the DC conversion module 520 are integrated in the same plug-in box, for example. With this arrangement, the overall layout of the power distribution module, the AC-DC module 510 and the DC conversion module 520 is more reasonable, thereby making the power distribution module, the AC-DC module 510 and the DC conversion module 520 more compact as a whole.

[0052] In another embodiment, the electrical compartment 130 is located at the top of the cabinet 100. In this configuration, when the bottom of the cabinet 100 is supported on the ground, the electrical compartment 130 can be located at the top of the cabinet 100, so that the electrical compartment 130 can be away from the ground, thereby reducing the possibility of water entering the electrical compartment 130.

[0053] For further reference, Figure 1 As shown, the heat exchange chamber 110 is located at the top of the cabinet 100, and the battery chamber 120 is located between the heat exchange chamber 110 and the electrical chamber 130. It should be noted that the "top" and "top" in the embodiment of the present application both refer to the top of the power exchange cabinet according to Figure 1 The arrangement shown refers to the method used.

[0054] In other optional embodiments, the electrical compartment 130 may also be located in the middle of the cabinet 100 or at the bottom of the cabinet 100 .

[0055] In another embodiment, the second heat exchanger 230 and the third heat exchanger 280 are arranged in series. The series arrangement has lower requirements on the flow rate of the entire liquid delivery circuit 300, thereby lowering the requirements on the pressurizing device 240, thereby making the cost of the pressurizing device 240 lower.

[0056] As a specific implementation method, refer to Figure 2 As shown, the liquid delivery circuit 300, for example, includes a third branch 330, and the third heat exchanger 280, for example, is arranged on the third branch 330. The third branch 330, for example, is arranged in series with the first branch 310 and the liquid delivery branch 400 mentioned above, thereby making the second heat exchanger 230 and the third heat exchanger 280 arranged in series.

[0057] During specific use, the heat exchange liquid flows sequentially through the third branch 330 and the first branch 310 or sequentially through the third branch 330 and the liquid delivery branch 400. In particular, when the heat exchange liquid flows sequentially through the third branch 330 and the first branch 310, the heat exchange liquid, for example, first exchanges heat with the electrical compartment 130, and at this time, the heat exchange liquid, for example, absorbs at least part of the heat of the electrical compartment 130, and then when the heat exchange liquid flows through the first branch 310, the heat exchange liquid, for example, can exchange heat with the outside air through the second heat exchanger 230, so that at least part of the heat absorbed by the heat exchange liquid can be dissipated.

[0058] In other optional embodiments, the second heat exchanger 230 and the third heat exchanger 280 may also be arranged in parallel.

[0059] In another embodiment, reference Figures 1 to 3As shown, the number of battery compartments 120 and first heat exchangers 220 is at least two, and each battery compartment 120 is provided with at least one first heat exchanger 220, and at least two battery compartments 120 are divided into multiple battery compartment groups, that is, all battery compartments 120 are divided into multiple battery compartment groups, and the battery compartment group may include one battery compartment 120, or may include at least two battery compartments 120, and the number of battery compartments 120 included in each battery compartment group may be the same or different. Each first heat exchanger 220 corresponding to each battery compartment group is arranged on the same second branch 320, and is arranged in sequence along the extension direction of the second branch 320, and each second branch 320 is arranged in parallel, and the two ends of each second branch 320 in its own extension direction are respectively connected to the liquid storage container 210 and the second heat exchanger 230. Specifically, the two ends of each second branch 320 in its own extension direction are, for example, respectively connected to the liquid outlet of the liquid storage container 210 and the third branch 330 described above. During specific use, the heat exchange liquid flows through the second branch path 320 while sequentially passing through each of the first heat exchangers 220 disposed on the second branch path 320 .

[0060] In this embodiment, at least two first heat exchangers 220 are arranged in parallel. With this arrangement, mutual interference between the first heat exchangers 220 is less, and when one of the first heat exchangers 220 is damaged, some of the first heat exchangers 220 can still operate normally.

[0061] In other optional embodiments, the first heat exchangers 220 may also be arranged in series in sequence. In this case, the first heat exchangers 220 are, for example, arranged in series on the same fourth branch, and the two ends of the fourth branch in its own extension direction are, for example, respectively connected to the liquid storage container 210 and the second heat exchanger 230.

[0062] In another embodiment, the number of battery compartments 120 is at least two, each of the battery compartments 120 is correspondingly provided with at least one first heat exchanger 220, at least two battery compartments 120 are arranged in sequence along the first direction, and two battery compartments 120 adjacent to each other in the first direction share a compartment wall, and a first heat exchanger 220 is provided in the compartment wall shared by the two adjacent battery compartments 120. In this arrangement, the same first heat exchanger 220 can exchange heat with two adjacent battery compartments 120 at the same time, so that the number of first heat exchangers 220 can be reduced, thereby making the overall structure of the power exchange cabinet simpler and the cost lower.

[0063] Specifically, the first direction is, for example, the height direction of the cabinet 100, more specifically, for example Figure 1 The direction indicated by the arrow line A.

[0064] For further reference, Figure 1As shown, at least two battery compartments 120 include, for example, a first battery compartment 120a and a second battery compartment 120b, the first battery compartment 120a and the second battery compartment 120b are sequentially arranged along the first direction, the first battery compartment 120a includes a first compartment wall 121 and a second compartment wall 122, the second battery compartment 120b includes a third compartment wall 123 and the first compartment wall 121 mentioned above, the third compartment wall 123, the first compartment wall 121 and the second compartment wall 122 are sequentially arranged along the first direction, the first battery compartment 120a and the second battery compartment 120b share the first compartment wall 121, and the first heat exchanger 220 is provided in the first compartment wall 121, the second compartment wall 122 and the third compartment wall 123. In this way, the first battery compartment 120a and the second battery compartment 120b each correspond to at least two first heat exchangers 220, so that the heat exchange efficiency of the first battery compartment 120a and the second battery compartment 120b is relatively high.

[0065] In other optional embodiments, each first heat exchanger 220 may also be disposed in the inner cavity of its corresponding battery compartment 120 .

[0066] In another embodiment, the battery exchange cabinet further includes a heater 700, which is disposed in the liquid storage container 210 and can heat the heat exchange liquid. In this way, the temperature of the heat exchange liquid can be adjusted according to the heat exchange requirements of the battery compartment 120, thereby reducing energy waste.

[0067] During specific use, the heater 700 is turned on to heat the heat exchange liquid, thereby increasing the temperature of the heat exchange liquid. When the temperature of the battery compartment 120 is lower than the preset temperature, the temperature of the heat exchange liquid is adjusted so that the temperature of the heat exchange liquid is not lower than the preset temperature. When the heat exchange liquid exchanges heat with the battery compartment 120, the battery compartment 120 can absorb at least part of the heat of the heat exchange liquid, thereby increasing the temperature of the battery compartment 120.

[0068] In other optional embodiments, the power exchange cabinet may not include the heater 700.

[0069] In another embodiment, reference Figure 1 and Figure 2 As shown, the power exchange cabinet also includes a flow detection device 800 , which is disposed in the liquid delivery circuit 300 and is used to detect the flow of the liquid delivery circuit 300 .

[0070] During specific use, when the liquid delivery circuit 300 is blocked, the actual flow rate of the liquid delivery circuit 300 will be less than the preset flow rate, so the flow rate of the liquid delivery circuit 300 is detected by the flow detection device 800, and the user can more easily and quickly determine whether the liquid delivery circuit 300 is blocked. In addition, with the help of the flow detection device 800, the user can more intuitively understand the flow rate of the liquid delivery circuit 300, so that the user can more easily and quickly adjust the flow rate of the liquid delivery circuit 300.

[0071] As a specific implementation, the flow detection device 800 is, for example, a flow sensor.

[0072] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
