Throughout the description of this application, unless otherwise specified, "plurality" means two or more.

[0050] As shown in the background art, in the prior art, the temperature of the battery pack may be too high during charging, resulting in low charging efficiency.

[0051] Based on this, the battery swap base provided in this application comprises a base body, a charging assembly, and a liquid cooling system. The base body is configured to connect to a support surface, and a support plate is provided on the base body to support the battery pack.

[0052] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below in conjunction with the drawings in the preferred embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions. The described embodiments are part of the embodiments of the present application, not all of the embodiments. The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain the present application, and should not be understood as limitations on the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0053] Reference Figures 1 to 4 As shown, the battery swap base provided in this application includes: a base body 100 for connecting to a support surface, a support plate 150 provided on the base body 100, and the support plate 150 for supporting the battery pack. A charging component 200 is provided on the support plate 150, and the charging component 200 is used to connect to the first connector of the battery pack so that the charging component 200 can charge the battery pack.

[0054] The liquid cooling system 300 includes: a first pipeline 310, which is arranged below the support plate 150, and contains coolant. The first pipeline 310 is used to connect to the inlet of the cooling pipeline of the battery pack through the support plate 150; a second pipeline 320, which is arranged below the support plate 150, and is used to connect to the outlet of the cooling pipeline through the support plate 150.

[0055] The driving member 340 is arranged below the support plate 150. The driving member 340 connects the first pipeline 310 and the second pipeline 320. The driving member 340 drives the coolant to circulate between the first pipeline 310, the cooling pipeline and the second pipeline 320 so that the coolant absorbs part of the heat of the battery pack.

[0056] Understandable, refer to Figure 4 As shown, the base body 100 provides a stable structural platform. A support plate 150 is provided on the base body 100. The support plate 150 provides support for the battery pack to ensure that the battery pack can be safely and securely placed during the battery pack replacement process. In a specific implementation, bolt holes can be provided at the bottom of the base body 100, and the base body 100 can be fixed outdoors with expansion bolts, or the base body 100 can be fixed to a vehicle-mounted crane with bolts, so that the battery replacement base can be flexibly moved with the vehicle. The embodiment of the present application does not impose too many restrictions on the various fixing forms of the base body 100.

[0057] It should be noted that a cover 500 may be provided on the base body 100 , and the cover 500 may be fixed to the base body 100 by bolts to provide protection against rain and dust.

[0058] The primary function of the charging assembly 200 is to charge the battery pack and transfer electrical energy to the battery pack. The charging assembly 200 is mounted on the support plate 150 to facilitate connection between the charging assembly 200 and the first connector of the battery pack, facilitating installation and improving operational efficiency. It should be noted that the charging assembly 200 may be equipped with necessary safety measures, such as overcurrent protection, overvoltage protection, and short-circuit protection, to ensure the safety of the charging process and prevent electrical failures.

[0059] The first pipeline 310, the second pipeline 320 and the driving member 340 are all arranged below the support plate 150, which can prevent the first pipeline 310, the second pipeline 320 and the driving member 340 from obstructing the connection path between the battery pack and the charging component 200, further improving the installation efficiency of the battery pack.

[0060] The main function of the first pipeline 310 is to transport coolant to the cooling pipeline of the battery pack. The flow of coolant can effectively remove the heat generated by the battery pack during charging and prevent the battery from overheating. The second pipeline 320 leads the coolant from the outlet of the cooling pipeline of the battery pack back to the liquid cooling system 300 to realize the circulation of the coolant, so that the heat can be removed and dissipated in the cooling system. It should be noted that the first pipeline 310 and the second pipeline 320 can be made of high-temperature resistant and corrosion-resistant materials to ensure their long-term use.

[0061] The driver 340 is used to drive the coolant to circulate between the first pipe 310, the cooling pipe, and the second pipe 320 to ensure that the coolant can flow effectively and remove heat. In a specific implementation, the driver 340 can be a water pump or a water cooling unit, and this embodiment of the application does not impose any additional restrictions on this.

[0062] It can be understood that compared with the prior art, the temperature of the battery pack may be too high during charging, resulting in low charging efficiency. The battery replacement base provided in this embodiment is provided with a base body 100, a charging component 200 and a liquid cooling system 300. The base body 100 is used to connect to the support surface, and a support plate 150 is provided on the base body 100. The support plate 150 is used to support the battery pack. The charging component 200 is arranged on the support plate 150 to facilitate the charging component 200 to charge the battery pack. The liquid cooling system 300 includes a first pipeline 310, a second pipeline 320 and a driving member 340. The first pipeline 310, the second pipeline 320 and the driving member 340 are all arranged below the support plate 150, which can avoid obstructing the connection path between the battery pack and the charging component 200, thereby improving the installation efficiency of the battery pack. The first pipe 310 contains coolant, and the first pipe 310 is connected to the inlet of the cooling pipe of the battery pack through the support plate 150, and the second pipe 320 is connected to the outlet of the cooling pipe through the support plate 150. The driving member 340 connects the first pipe 310 and the second pipe 320, and the driving member 340 drives the coolant to circulate between the first pipe 310, the cooling pipe and the second pipe 320, so that the coolant absorbs part of the heat of the battery pack. The battery replacement base provided in this application can absorb heat from the battery pack during charging, prevent the battery pack from overheating, and improve charging efficiency.

[0063] In some embodiments, reference Figure 4 and Figure 7 As shown, the support plate 150 has a first wire groove 151 , and the liquid cooling system 300 further includes a first joint 350 and a second joint 360 , both of which are arranged above the support plate 150 .

[0064] The first pipeline 310 is connected to the first joint 350 through the first wire groove 151, and the second pipeline 320 is connected to the second joint 360 through the first wire groove 151; the first joint 350 is used to communicate with the inlet of the cooling pipeline, and the second joint 360 is used to communicate with the outlet of the cooling pipeline.

[0065] Specifically, by providing the first wire channel 151, the first pipe 310 can be connected to the first connector 350, and the second pipe 320 can be connected to the second connector 360. Both the first connector 350 and the second connector 360 are arranged above the support plate 150, which facilitates the connection of the first pipe 310 and the second pipe 320 to the battery pack's cooling pipes, respectively, improving installation efficiency. The first connector 350 and the second connector 360 also serve as a guide, making the battery pack installation process simpler and faster, reducing operation time.

[0066] It should be noted that the first joint 350 and the second joint 360 should have good sealing performance to prevent leakage of the coolant.

[0067] In some embodiments, reference Figure 7 As shown, the battery swap base also includes a support assembly 400, which includes a first mounting plate 410 and a third connecting member 420. The first mounting plate 410 is arranged opposite to the first wire groove 151, and the first connector 350 and the second connector 360 are both arranged on the first mounting plate 410. The third connecting member 420 connects the first mounting plate 410 and the support plate 150.

[0068] It can be understood that by setting the first mounting plate 410, a mounting position is provided for the first joint 350 and the second joint 360, and the third connecting member 420 fixes the first mounting plate 410 to the support plate 150, ensuring a firm connection between the first mounting plate 410 and the base body 100, and preventing the first mounting plate 410 from being displaced or loosened during operation.

[0069] It should be noted that centrally installing the first connector 350 and the second connector 360 on the first mounting plate 410 can also simplify the layout and wiring of the liquid cooling system 300, improve the convenience of installation and maintenance, and reduce the possibility of installation errors.

[0070] It should also be noted that the third connecting member 420 can be a screw or other connecting components, and the embodiment of the present application does not impose too many restrictions on this.

[0071] In some embodiments, reference Figure 5 and Figure 6 As shown, the liquid cooling system 300 also includes a connecting component 330, which includes a first connecting member 331 and a second connecting member 332. The first connecting member 331 is sleeved on the first pipeline 310 or the second pipeline 320, and the second connecting member 332 connects the first connecting member 331 to the base body 100.

[0072] Specifically, the first connecting member 331 can be mounted on the first pipeline 310 or on the second pipeline 320. The second connecting member 332 fixes the first connecting member 331 to the base body 100 to ensure the stability of the connection. The first connecting member 331 and the second connecting member 332 are easy to assemble and disassemble, thereby facilitating the replacement and maintenance of the first pipeline 310 and the second pipeline 320.

[0073] It should be noted that a through hole can be set on the first connecting member 331, and the second connecting member 332 includes a bolt and a nut matching the bolt. The bolt is connected to the nut through the through hole and the base body 100 to fix the first connecting member 331 to the base body 100.

[0074] In some embodiments, reference Figure 5 and Figure 6As shown, two connecting parts 110 are provided on the base body 100 , and the second connecting member 332 is correspondingly connected to the first connecting member 331 and the connecting part 110 .

[0075] It can be understood that by providing a connecting portion 110 on the base body 100, a connection position is provided for the second connecting member 332. The second connecting member 332 fixes the first connecting member 331 and the first pipeline 310 (or the second pipeline 320) on the connecting portion 110, which can prevent the first pipeline 310 (or the second pipeline 320) from being displaced or loosened, thereby improving the stability and reliability of the liquid cooling system 300.

[0076] In a specific implementation, the connecting portion 110 can extend in either a horizontal or vertical direction, as long as it facilitates securing the first pipe 310 or the second pipe 320. This embodiment of the present application does not impose any particular limitations on this. It should be noted that the connecting portion 110 can be provided with a connection hole, through which the second connecting member 332 is connected to the first connecting member 331.

[0077] In some embodiments, reference Figure 3 and Figure 4 As shown, the liquid cooling system 300 further includes an expansion kettle 370 . The expansion kettle 370 is disposed on one side of the base body 100 , and the expansion kettle 370 is in communication with the first pipeline 310 .

[0078] It should be noted that the expansion kettle 370 can be used as a storage and replenishment point for the coolant. When the coolant in the first pipeline 310 is reduced, the expansion kettle 370 can replenish the coolant to ensure that the liquid cooling system 300 always has enough coolant for circulation and heat absorption.

[0079] The expansion kettle 370 can also be used to regulate pressure changes within the liquid cooling system 300. When the coolant expands or contracts due to temperature changes, the expansion kettle 370 provides a buffer space to absorb these volume changes, preventing the pressure in the first pipeline 310, the cooling pipeline and the second pipeline 320 from being too high or too low, thereby protecting them from damage caused by pressure fluctuations.

[0080] It should also be noted that the liquid cooling system 300 may further include a power supply box 380 , which is connected to the base body 100 via bolts. The power supply box 380 may be connected to an external 220V power supply to power the liquid cooling system 300 .

[0081] A high voltage box 600 may also be installed on the base body 100 to manage and distribute high voltage power from an external power source to ensure safe transmission of power.

[0082] In some embodiments, reference Figure 3 、 Figure 4 and Figure 8As shown, the charging assembly 200 includes a second connector 210, a second mounting plate 220 and a fourth connector 230. The second connector 210 is connected to the second mounting plate 220. The second connector 210 is used to connect to the first connector. The fourth connector 230 connects the second mounting plate 220 and the support plate 150.

[0083] It can be understood that the second connector 210 serves as an interface for power transmission, and is used to connect to the first connector of the battery pack to realize the charging function, ensuring that electrical energy can be efficiently and safely transmitted to the battery pack.

[0084] The second mounting plate 220 provides a stable mounting platform for the second connector 210, ensuring that it remains stable during operation and reducing loosening or damage caused by vibration or external forces. By integrating the second connector 210 on the second mounting plate 220, the installation and maintenance process is simplified, the installation efficiency is improved, and subsequent inspection and repair are facilitated. The fourth connecting member 230 fixes the second mounting plate 220 to the support plate 150 to ensure a stable connection between the mounting plate and the support plate 150. In a specific implementation, the fourth connecting member 230 can be a guide screw or other connecting component, and the embodiments of the present application do not impose too many restrictions on this.

[0085] In some embodiments, reference Figure 8 As shown, the charging assembly 200 further includes an elastic member 240 , which is sleeved on the fourth connecting member 230 , and two ends of the elastic member 240 are respectively in contact with the second mounting plate 220 and the support plate 150 .

[0086] It is understood that the elastic member 240 provides a certain degree of elasticity, allowing the second mounting plate 220 to be raised and lowered relative to the support plate 150 within a certain range. This provides a buffer between the second connector 210 on the support plate 150 and the first connector of the battery pack when the battery pack is installed, thereby allowing the first connector to smoothly engage with the second connector 210. For example, the elastic member 240 may be a spring.

[0087] In some embodiments, reference Figure 1 and Figure 8 As shown, the support plate 150 has a second wire groove 152, and the charging assembly 200 also includes a charging box 250 and a connecting line 260. The charging box 250 is arranged below the support plate 150. The connecting line 260 electrically connects the charging box 250 to the second connector 210 through the second wire groove 152. The charging box 250 is used for an external charging gun.

[0088] It should be noted that the charging box 250 provides a centralized interface for connecting an external charging gun, which simplifies the charging process, facilitates the connection of the charging gun with the charging component 200, improves the convenience and efficiency of the charging operation, and reduces the trouble of the user during the connection process.

[0089] Specifically, by providing the second wire groove 152, a wire passage is provided for the connecting wire 260, so that the connecting wire 260 electrically connects the charging box 250 to the second connector 210. The charging box 250 is used to connect an external charging gun. The charging box 250 can have a dual-gun interface for dual-gun charging. In specific implementation, the charging box 250 can be connected to the base body 100 by bolts, or other methods can be used for connection. This embodiment of the application does not impose too many restrictions on this.

[0090] In some embodiments, reference Figure 4 As shown, at least one buffer pad 120 is provided on the base body 100 , and the top of the buffer pad 120 is higher than the support plate 150 , and the buffer pad 120 is used to contact the battery pack.

[0091] In a specific implementation, the buffer pad 120 contacts the battery pack to play a buffering role. The buffer pad 120 can be a rubber pad that can be connected to the base body 100 by bolts.

[0092] It should be noted that a primary guide 130 and a secondary guide 140 can also be provided on the base body 100 to facilitate the rough positioning and fine positioning of the battery pack during battery replacement installation, so that the battery pack can be installed on the base body 100 smoothly and accurately.

[0093] Those skilled in the art will appreciate that by providing the base body 100, the charging assembly 200, and the liquid cooling system 300, the base body 100 is configured to connect to a support surface, and a support plate 150 is provided on the base body 100 to support the battery pack. The charging assembly 200 is mounted on the support plate 150 to facilitate charging the battery pack. The liquid cooling system 300 includes a first pipeline 310, a second pipeline 320, and a driver 340. These first pipelines 310, 320, and driver 340 are all positioned below the support plate 150 to avoid obstruction in the connection path between the battery pack and the charging assembly 200, thereby improving battery pack installation efficiency. The first pipeline 310 contains coolant and is connected to the inlet of the battery pack's cooling pipeline via the support plate 150. The second pipeline 320 is connected to the outlet of the cooling pipeline via the support plate 150. The driving member 340 connects the first pipe 310 and the second pipe 320. The driving member 340 drives the coolant to circulate between the first pipe 310, the cooling pipe, and the second pipe 320, so that the coolant absorbs part of the heat of the battery pack.
