[0075] From the perspective of market development, with the development of new energy technology, the application of power batteries is becoming more and more extensive. Power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as military equipment and aerospace and other fields. With the continuous expansion of the application field of power batteries, the market demand is also constantly expanding.

[0076] When the power of an electrical device runs out, it is often supplemented by connecting to a charging device. For example, an electric vehicle or a hybrid vehicle can be connected to a charging station for charging. In addition, the power can also be quickly supplemented by replacing the battery. Usually, a special device (i.e., a battery replacement device) is required to replace the battery. The battery replacement device removes the low-power battery (i.e., the battery to be charged) on the electrical device and transports it to the charging device to replenish the power, and transports the fully charged battery (i.e., the fully charged battery) to the electrical device for installation.

[0077] Electrical devices usually replace batteries at battery swap stations, and storage equipment is set up in the battery swap stations to store battery devices and provide battery devices to the battery swap devices. When the number of batteries retained at the battery swap station fluctuates, it is necessary to transfer the batteries so that the number of battery storage bins at each battery swap station is evenly distributed. At present, trucks are usually used to transport and allocate batteries so that batteries can be transferred between stations, and conventional trucks are generally only equipped with cargo platforms or cargo boxes. It is inconvenient to place and fix battery devices on trucks, and batteries are easily bumped during transportation. If the cargo box of the truck is set as a special shelf for fixing batteries, the truck can only be idle when there is no need to transfer batteries, and it is difficult to use it to transport other goods.

[0078] Based on the above considerations, in order to reduce the risk of damage to the battery device 200 during transportation, a battery transport vehicle 100 is designed. The battery transport vehicle 100 includes a chassis assembly 10 and a wheel assembly 20 and a cargo assembly 30 arranged on the chassis assembly 10. The chassis assembly 10 includes a chassis 11 and a battery bracket 12. The battery bracket 12 is arranged on the chassis 11 and is provided with a plurality of mounting spaces 125 for accommodating the battery device 200. The cargo assembly 30 is arranged above the chassis assembly 10; the entrance and exit of the mounting space 125 are located on the side of the chassis assembly 10 away from the cargo assembly 30.

[0079] The present application provides a battery bracket 12 for fixing and installing the battery device 200 on the chassis assembly 10 of the battery transport vehicle 100, so as to facilitate the placement and fixing of the battery device 200 on the battery transport vehicle 100. The battery bracket 12 is used to fix the battery device 200, so that the placement of the battery device 200 is relatively stable, and the risk of collision of the battery device 200 during transportation can be reduced. In addition, the cargo assembly 30 on the battery transport vehicle 100 can be used to place other items, and when there is no need to deliver batteries, it can be used to transport other goods, thereby improving the flexibility and utilization of the battery transport vehicle 100.

[0080] The electric device mentioned in the embodiments of the present application may be, but is not limited to, a mobile phone, a tablet, a laptop computer, an electric toy, an electric tool, a battery car, an electric car, a ship, a spacecraft, etc. Among them, the electric toy may include a fixed or mobile electric toy, for example, a game console, an electric car toy, an electric ship toy, and an electric airplane toy, etc., and the spacecraft may include an airplane, a rocket, a space shuttle, and a spacecraft, etc. The battery replacement device 2 may disassemble the battery device 200 in the electric device, and may also install the battery device 200 in the electric device.

[0081] The battery device 200 includes a case and a battery cell, and the battery cell is contained in the case. The case is used to provide a storage space for the battery cell, and the case can adopt a variety of structures. In some embodiments, the case may include a first part and a second part, the first part and the second part cover each other, and the first part and the second part jointly define a storage space for accommodating the battery cell. The second part can be a hollow structure with one end open, and the first part can be a plate-like structure, and the first part covers the open side of the second part, so that the first part and the second part jointly define a storage space; the first part and the second part can also be hollow structures with one side open, and the open side of the first part covers the open side of the second part. Of course, the case formed by the first part and the second part can be in a variety of shapes, such as a cylinder, a cuboid, etc.

[0082] In the battery device 200, there may be multiple battery cells, and the multiple battery cells may be connected in series, in parallel, or in a mixed connection. A mixed connection means that the multiple battery cells are both connected in series and in parallel. The multiple battery cells may be directly connected in series, in parallel, or in a mixed connection, and then the whole formed by the multiple battery cells is accommodated in a box; of course, the battery device 200 may also be a battery module formed by connecting multiple battery cells in series, in parallel, or in a mixed connection, and then the multiple battery modules are connected in series, in parallel, or in a mixed connection to form a whole, and accommodated in a box. The battery device 200 may also include other structures. For example, the battery device 200 may also include a busbar component for realizing electrical connection between multiple battery cells.

[0083] Each battery cell may be a secondary battery or a primary battery, or a lithium-sulfur battery, a sodium-ion battery, or a magnesium-ion battery, but is not limited thereto. The battery cell may be cylindrical, flat, rectangular, or in other shapes.

[0084] According to some embodiments of the present application, in combination with reference Figures 1 to 3 as well as Figure 6 , Figure 1 It is a structural schematic diagram of a battery transport vehicle 100 proposed according to some embodiments of the present application; Figure 2 This is a structural diagram of a battery transport vehicle 100 with a cargo box removed according to some embodiments of the present application. Figure 3 This is a top view of a battery transporter 100 with the cargo box removed according to some embodiments of the present application. Figure 6 It is a schematic diagram of a chassis assembly 10 provided according to one embodiment of the present application and equipped with a battery device 200 for supplying power to a battery transport vehicle 100 .

[0085] As shown in the figure, the first direction X is the length direction of the battery transport vehicle 100, that is, the arrangement direction of the front 40 and the rear of the battery transport vehicle 100, the second direction Y is the width direction of the battery transport vehicle 100, the second direction Y is perpendicular to the first direction X and the height direction of the battery transport vehicle 100, and the third direction Z is the height direction of the battery transport vehicle 100.

[0086] The battery transport vehicle 100 proposed in the present application includes a chassis assembly 10 and a wheel assembly 20 and a cargo assembly 30 arranged on the chassis assembly 10. The chassis assembly 10 includes a chassis 11 and a battery bracket 12. The battery bracket 12 is arranged on the chassis 11 and is provided with a plurality of mounting spaces 125 for accommodating the battery device 200. The cargo assembly 30 is arranged above the chassis assembly 10; the entrance and exit of the mounting space 125 are located on the side of the chassis assembly 10 away from the cargo assembly 30.

[0087] In the embodiment of the present application, the battery transport vehicle 100 can be a fuel vehicle, a gas vehicle or a new energy vehicle, and the new energy vehicle can be a pure electric vehicle, a hybrid vehicle or an extended-range vehicle, etc. The battery transport vehicle 100 includes a chassis assembly 10 as a base, and the chassis assembly 10 can support and connect various assemblies of the battery transport vehicle 100, such as connecting structures such as the wheel assembly 20 and the cargo assembly 30; so that each assembly maintains a relatively correct position and bears various loads inside and outside the battery transport vehicle 100.

[0088] The wheel assembly 20 may include components such as wheels, axles, and suspensions, so that the chassis assembly 10 can still travel stably under various road conditions; the battery transporter 100 also includes a drive assembly responsible for transmitting the power of the engine to the wheels, and the drive assembly may include components such as a clutch, a gearbox, and a drive shaft. The cargo assembly 30 can be configured as a cargo box, a cargo platform, a shelf, or other structure, which can be used to place the goods to be transported. In some embodiments, the battery transporter 100 also includes a front 40, which can be configured as a cab; of course, in some embodiments, the battery transporter 100 can also be unmanned.

[0089] The chassis assembly 10 includes a chassis 11 and a battery holder 12 disposed on the chassis 11. The battery holder 12 is provided with a plurality of mounting spaces 125, and the battery device 200 can be fixed in the mounting space 125. The chassis 11 is used as a base structure to support and connect the various assemblies of the battery transport vehicle 100, such as connecting the wheel assembly 20 and the cargo assembly 30 and other structures, so as to bear various loads inside and outside the battery transport vehicle 100. The chassis 11 can be composed of a plurality of beams 111, or can be set as a frame structure; the cargo assembly 30, the wheel assembly 20 and the front 40 and other structures are fixed on the chassis 11. The shape of the mounting space 125 formed by the battery holder 12 is adapted to the battery device 200 to be carried, so as to better fix the battery device 200, improve the placement stability of the battery device 200, and avoid the battery device 200 from shaking and bumping. The battery bracket 12 may also be provided with a connection structure for limiting and locking the battery device 200 , so as to further improve the stability of the battery device 200 being fixed in the mounting space 125 .

[0090] Please refer to Figure 5 In some embodiments, the battery device 200 can enter the mounting space 125 along the height direction of the battery transport vehicle 100 (i.e., the third direction Z in the figure) and move out from the bottom of the chassis assembly 10. Specifically, the battery device 200 can enter the mounting space 125 upward from the ground-facing side of the chassis assembly 10 to be fixed to the battery bracket 12; when the battery device 200 is removed, the battery device 200 moves downward out of the mounting space 125. Of course, it is also possible to enter the mounting space 125 along the width direction of the battery transport vehicle 100 (i.e., the second direction Y in the figure) or the length direction of the chassis assembly 10 (i.e., the first direction X in the figure), which is not limited here.

[0091] This arrangement allows the battery device 200 to be stored on the battery bracket 12 of the chassis assembly 10, which is specifically used to place the battery device 200, thereby improving the stability of the battery device 200 carried in the battery transport vehicle 100 and reducing the risk of the battery device 200 being bumped during transportation. In addition, the battery device 200 will not occupy the space above the chassis assembly 10, and the cargo assembly 30 disposed above the chassis assembly 10 can still be used to load other goods. When the battery device 200 is not needed to be transported, the battery transport vehicle 100 can be used to transport other goods, thereby improving the applicability of the battery transport vehicle 100.

[0092] The entrance and exit of the mounting space 125 is located on the side of the chassis assembly 10 away from the cargo assembly 30; in the battery transport vehicle 100, the cargo assembly 30 is fixed above the chassis assembly 10 along the height direction of the battery transport vehicle 100 (i.e., the third direction Z in the figure), and the battery device 200 can enter and exit the mounting space 125 from the side of the chassis assembly 10 away from the cargo assembly 30, i.e., from the bottom of the chassis assembly 10. Specifically, the battery device 200 can enter the mounting space 125 upward from the ground side of the chassis assembly 10 to be fixed to the battery bracket 12; when the battery device 200 is removed, the battery device 200 is moved downward out of the mounting space 125.

[0093] In some embodiments, the battery device 200 for powering the battery transporter 100 can be installed in one of the mounting spaces 125 of the battery bracket 12, so that there is no need to set other brackets in the battery transporter 100 to fix the battery device 200 of the battery transporter 100 itself. Of course, other installation methods can also be used to fix the battery device 200 of the battery transporter 100 itself. In addition, the battery device 200 carried in the battery bracket 12 of the battery transporter 100 can also be used as a backup battery for the battery transporter 100 to increase the cruising range of the battery transporter 100.

[0108] Please refer to Figure 8 According to some embodiments of the present application, the battery holder 12 further includes a cover structure 121, which covers at least a portion of the mounting space 125 to at least shield the region where the interface structure 202 of the battery device 200 in the mounting space 125 is located.

[0109] Please refer to Fig. 9The interface structure 202 of the battery device 200 at least includes an electrical connection structure 2021, which is used to electrically connect the battery device 200 to other devices. In some embodiments, the interface structure 202 also includes a water connection structure 2022, which is used to connect the battery device 200 to the liquid cooling system. In this embodiment, the battery bracket 12 includes a cover structure 121, which is arranged above the mounting space 125, and can be arranged to cover the entire area of ​​the mounting space 125, or only a part of the mounting space 125; when the battery device 200 is arranged in the mounting space 125, the cover structure 121 can at least shield the interface structure 202 of the battery device 200, thereby protecting the interface structure 202 of the battery device 200, avoiding the interface structure 202 of the battery device 200 from being damaged by collision, and avoiding foreign matter from entering the interface structure 202 of the battery device 200.

[0110] Please refer to Figure 8 According to some embodiments of the present application, the cover structure 121 includes a cover body 1211 and a connector assembly 1212. The cover body 1211 is disposed in the mounting space 125, and the connector assembly 1212 is disposed in the cover body 1211. The connector assembly 1212 is configured to dock with the interface structure 202 of the battery device 200.

[0111] In this embodiment, the cover structure 121 includes a cover body 1211 as a base, and the cover body 1211 can be set above the entire mounting space 125, or can be set to cover a partial area of ​​the mounting space 125. The connector assembly 1212 includes at least an electrical connector 1213, and the electrical connector 1213 is used to connect with the electrical connection structure 2021 of the battery device 200; when the battery device 200 is also provided with a water connection structure 2022, the connector assembly 1212 can also include a water connector 1214 for connecting with the water connection structure 2022. The connector component 1212 is disposed on the cover body 1211. The connector component 1212 can be disposed on the side of the cover body 1211 facing the mounting space 125, or the connector component 1212 can be passed through the cover body 1211 along the height direction of the battery transporter 100 (i.e., the third direction Z in the figure), or the connector component 1212 can be disposed on the side of the cover body 1211 facing away from the mounting space 125, and a corresponding avoidance opening is disposed on the cover body 1211 opposite to the connector component 1212, so that when the battery device 200 is disposed in the mounting space 125, the interface structure 202 of the battery device 200 can pass through the avoidance opening and dock with the connector component 1212.

[0112] By adopting the above manner, when the battery device 200 is disposed in the mounting space 125 , the interface structure 202 of the battery device 200 is adapted to be connected with the connecting assembly, which can better protect the interface structure 202 of the battery device 200 .

[0113] Optionally, the connector assembly 1212 can adopt a connection structure used in an electrical device to connect a battery device 200. In this case, the connector assembly 1212 also has a connection end for connecting a cable and / or a water pipe, and the connection end is located outside the mounting space 125. For the mounting space 125 used to place the transported battery device 200, it is not necessary to connect the cable and the water pipe on the connector assembly 1212 corresponding to the mounting space 125. In some embodiments, the battery device 200 in part of the mounting space 125 can be used to provide power to the battery transporter 100. In this case, the connector assembly 1212 on the mounting space 125 can be used to connect the cable and the water pipe in the battery transporter 100, so that the battery device 200 in the mounting space 125 can be connected to the circuit and liquid cooling system in the battery transporter 100 through the connector assembly 1212.

[0114] Please refer to Figure 8 According to some embodiments of the present application, the connector assembly 1212 includes an electrical connector 1213 and a water connector 1214 .

[0115] In this embodiment, the connector assembly 1212 includes an electrical connector 1213 for docking with the electrical connection structure 2021 of the battery device 200, and a water connector 1214 for docking with the water connection structure 2022 of the battery device 200. The electrical connection structure 2021 and the water connection structure 2022 are protected respectively by the electrical connector 1213 and the water connector 1214, so that both the electrical connection structure 2021 and the water connection structure 2022 of the battery device 200 can be well protected.

[0116] Please refer to Figure 7 and Figure 8 According to some embodiments of the present application, the battery holder 12 further includes a blocking mechanism 122, and the blocking mechanism 122 is used to block the interface end of the connector assembly 1212 when the mounting space 125 is in an empty state.

[0117] In this embodiment, the interface end of the connector assembly 1212 refers to the end of the connector assembly 1212 used to dock with the interface structure 202 of the battery device 200, and the interface end is arranged toward the mounting space 125. The blocking mechanism 122 can be set as a cover, a sealing plug or other blocking member. Optionally, the blocking mechanism 122 can be manually operated to block the interface end of the connector assembly 1212, or removed from the interface end to open the interface end circuit; a driving component 1221 can also be set in the blocking mechanism 122 to drive the blocking member to move, so that the blocking member blocks or opens the interface end of the connector assembly 1212.

[0118] By setting up the blocking mechanism 122, when the battery device 200 is not installed in the mounting space 125, that is, when the mounting space 125 is in a vacant state, the blocking mechanism 122 can be used to block the interface end of the connector assembly 1212, thereby preventing rainwater, mud or other foreign matter from entering the interface end of the connector assembly 1212, so as to avoid damage to the interface structure 202 of the battery device 200 when the battery device 200 is installed in the mounting space 125.

[0119] Please refer to Figure 6 In some embodiments, at least one mounting space 125 in the battery holder 12 is used to install a battery device 200 that provides electrical energy to the battery transporter 100. Since the battery device 200 is always installed in the mounting space 125, there is no need to set a corresponding blocking mechanism 122 in the mounting space 125.

[0120] Please refer to Figure 8 According to some embodiments of the present application, the blocking mechanism 122 includes a blocking piece (not shown) and a driving assembly 1221. The blocking piece is arranged on the side of the cover body 1211 facing the mounting space 125. The driving assembly 1221 is transmission-connected to the blocking piece for driving the blocking piece to move to block or open the interface end.

[0121] In this embodiment, the blocking member may be movable in the form of, but not limited to, flipping, rotating or translating along the surface of the cover body 1211. Optionally, the drive assembly 1221 may also be used to drive the blocking member to approach or move away from the interface end in the docking direction of the connector assembly 1212.

[0122] The driving component 1221 may be provided with a motor or a cylinder as a driving member, and the driving member may be directly connected to the blocking member to drive the blocking member to move, for example, the output shaft of the motor may be connected to the blocking member, or a rotary cylinder may be provided to connect the blocking member to drive the blocking member to rotate or flip; a linear cylinder may also be provided to connect the blocking member to drive the blocking member to translate and cover or reveal the interface end of the connector component 1212. Optionally, the driving component 1221 may also include a gear transmission, a gear rack transmission, a belt transmission, a connecting rod transmission or other transmission structures, and the driving member is connected to the blocking member through the transmission structure.

[0123] In one embodiment, the connector assembly 1212 includes an electrical connector 1213 and a water connector 1214 , and the blocking mechanism 122 is provided with a first blocking member for blocking the electrical connector 1213 and a second blocking member for blocking the water connector 1214 .

[0124] This arrangement enables the blocking member to move by driving the driving component 1221, and eliminates the need for manual operation of the blocking member to cover the interface end of the connector component 1212 or to leave the interface end open, thereby improving the degree of automation and ease of use.

[0125] Please refer to Figure 8 According to some embodiments of the present application, the driving component 1221 includes a first driving member 1222 and a second driving member 1223. The first driving member 1222 is in transmission cooperation with the blocking member to drive the blocking member to move so that the blocking member and the interface end are relative or staggered; the second driving member 1223 is in transmission cooperation with the first driving member 1222 to drive the first driving member 1222 to move so as to drive the blocking member to move closer to or away from the cover body 1211.

[0126] In this embodiment, the first driving member 1222 is used to drive the blocking member to switch between the avoidance position misaligned with the interface end and the shielding position relative to the interface end, and the first driving member 1222 can be configured to drive the blocking member to slide or rotate. The first driving member 1222 can be set as a motor or a cylinder. The first driving member 1222 can be directly connected to the blocking member, or can be connected to the blocking member through gear transmission, gear rack transmission, belt transmission, connecting rod transmission or other transmission structures. The second driving member 1223 is used to drive the first driving member 1222 to move so that the first driving member 1222 drives the blocking member to move, so that the blocking member moves from the mounting space 125 to the side of the cover body 1211, or from the cover body 1211 to the side of the mounting space 125, so that the blocking member is close to or away from the cover body 1211, and when the blocking member is in the shielding position relative to the interface end, the blocking member is close to or away from the interface end. Optionally, the second driving member 1223 can be set as a linear cylinder or a telescopic motor.

[0127] In specific applications, when the mounting space 125 is in an empty state and there is no need to install the battery device 200 temporarily, the second driving member 1223 drives the first driving member 1222 to drive the blocking member to move, so that the blocking member moves from the cover body 1211 to the side of the mounting space 125 and away from the cover body 1211, and then the first driving member 1222 drives the blocking member to move, so that the blocking member moves from the avoidance position misaligned with the interface end to the shielding position opposite to the interface end, and the second driving member 1223 drives the first driving member 1222 to drive the blocking member to move, so that the blocking member is close to the interface end of the cover body 1211 and the connector assembly 1212, so that the blocking member is docked with the interface end to close the interface end.

[0128] In this way, the second driving member 1223 can make the blocking member approach and move away from the cover body 1211, avoiding friction or collision with the cover body 1211 or the interface end when the first driving member 1222 drives the blocking member to move; and the second driving member 1223 drives the blocking member to approach the interface end and dock with the interface end to avoid a gap between the blocking member and the interface end, thereby achieving better sealing and protection.

[0129] According to some embodiments of the present application, the first driving member 1222 is configured to drive the blocking member to rotate.

[0130] In this embodiment, the first driving member 1222 drives the blocking member to rotate so that the blocking member switches between the avoidance position and the shielding position. The first driving member 1222 can be set as a driving motor or a rotary cylinder, so that the blocking member is connected to the output shaft of the driving motor or the rotating member of the rotary cylinder. Of course, a transmission structure can also be set between the first driving member 1222 and the air duct member, which is not limited here.

[0131] In some embodiments, the sealing mechanism 122 includes a first sealing member and a second sealing member, which are used to respectively seal the electrical connector 1213 and the water connector 1214 of the connector assembly 1212. The first sealing member and the second sealing member can be connected to the first driving member 1222, and the first driving member 1222 can simultaneously drive the first sealing member and the second sealing member to rotate about the same rotation axis, thereby simplifying the structure and reducing the volume and occupied space of the sealing mechanism 122.

[0132] Please refer to Figure 8 According to some embodiments of the present application, the first driving member 1222 is configured as a rotating cylinder; with this configuration, the first driving member 1222 can be directly connected to the blocking member to drive the blocking member to rotate, and there is no need to set up a large number of transmission structures, which is beneficial to simplifying the structure of the blocking mechanism 122 and reducing the volume, and the reliability of the cylinder drive is higher.

[0133] Please refer to Figure 8In some embodiments, the second driving member 1223 is configured as a linear cylinder. In this configuration, the second driving member 1223 can be directly connected to the first driving member 1222 to drive the second driving member 1223 to move, and there is no need to configure more transmission structures, which is conducive to simplifying the structure of the blocking mechanism 122 and reducing the volume. In addition, the cylinder drive has a higher reliability.

[0134] According to some embodiments of the present application, a groove is provided on one side of the cover body 1211 facing the mounting space 125 , and the groove is offset from the interface end, and the blocking member can be received in the groove.

[0135] In this embodiment, when there is no need to block the interface end of the connector assembly 1212, the first driving member 1222 drives the blocking member to move to a position offset from the interface end, so that the blocking member moves to face the groove of the cover body 1211; then the second driving member 1223 drives the first driving member 1222 to move so as to drive the blocking member into the groove. With such a configuration, the blocking member can avoid the battery device 200 in the mounting space 125, avoid collision with the blocking member when the battery device 200 is installed in the mounting space 125, and reduce the risk of damage to the battery device 200.

[0136] Please refer to Figure 7 and Figure 8 According to some embodiments of the present application, at least part of the driving assembly 1221 is disposed on a side of the cover body 1211 facing away from the mounting space 125 .

[0137] In this embodiment, a through hole may be provided on the cover body 1211 for passing through a connection structure between the blocking member and the drive assembly 1221, such as for passing through an output shaft of a motor, a piston rod of a cylinder, or a rotating member, or other transmission structures. By disposing a part of the structure of the drive assembly 1221 on the side of the cover body 1211 away from the mounting space 125, collision between the drive assembly 1221 and the battery device 200 in the mounting space 125 can be avoided.

[0138] Please refer to Figure 7 According to some embodiments of the present application, the present application also proposes a chassis assembly 10, the chassis assembly 10 includes a chassis 11 and a battery holder 12 arranged on the chassis 11, the battery holder 12 is arranged on the chassis 11, and is provided with a plurality of mounting spaces 125 for accommodating the battery device 200, and the entrance and exit of the mounting space 125 are arranged downward.

[0139] In the embodiment of the present application, the battery transport vehicle 100 can be a fuel vehicle, a gas vehicle or a new energy vehicle, and the new energy vehicle can be a pure electric vehicle, a hybrid vehicle or an extended-range vehicle, etc. The battery transport vehicle 100 includes a chassis assembly 10 as a base, and the chassis assembly 10 can support and connect various assemblies of the battery transport vehicle 100, such as connecting structures such as the wheel assembly 20 and the cargo assembly 30; so that each assembly maintains a relatively correct position and bears various loads inside and outside the battery transport vehicle 100.

[0140] The chassis assembly 10 includes a chassis 11 and a battery holder 12 disposed on the chassis 11. The battery holder 12 is provided with a plurality of mounting spaces 125, and the battery device 200 can be fixed in the mounting space 125. The chassis 11 is used as a base structure to support and connect the various assemblies of the battery transport vehicle 100, such as connecting the wheel assembly 20 and the cargo assembly 30 and other structures, so as to bear various loads inside and outside the battery transport vehicle 100. The chassis 11 can be composed of a plurality of beams 111, or can be set as a frame structure; the cargo assembly 30, the wheel assembly 20 and the front 40 and other structures are fixed on the chassis 11. The shape of the mounting space 125 formed by the battery holder 12 is adapted to the battery device 200 to be carried, so as to better fix the battery device 200, improve the placement stability of the battery device 200, and avoid the battery device 200 from shaking and bumping. The battery bracket 12 may also be provided with a connection structure for limiting and locking the battery device 200 , so as to further improve the stability of the battery device 200 being fixed in the mounting space 125 .

[0141] Please refer to Figure 5 In some embodiments, the entrance and exit of the mounting space 125 are arranged downward, and the battery device 200 can enter the mounting space 125 along the height direction of the battery transport vehicle 100 (i.e., the third direction Z in the figure) and move out from the bottom of the chassis assembly 10. Specifically, the battery device 200 can enter the mounting space 125 upward from the ground-facing side of the chassis assembly 10 to be fixed to the battery bracket 12; when the battery device 200 is removed, the battery device 200 moves downward out of the mounting space 125. Of course, it is also possible to enter the mounting space 125 along the width direction of the battery transport vehicle 100 (i.e., the second direction Y in the figure) or the length direction of the chassis assembly 10 (i.e., the first direction X in the figure), which is not limited here.

[0142] This arrangement allows the battery device 200 to be stored on the battery bracket 12 of the chassis assembly 10, which is specifically used to place the battery device 200, thereby improving the stability of the battery device 200 carried in the battery transport vehicle 100 and reducing the risk of the battery device 200 being bumped during transportation. In addition, the battery device 200 will not occupy the space above the chassis assembly 10, and the cargo assembly 30 disposed above the chassis assembly 10 can still be used to load other goods. When the battery device 200 is not needed to be transported, the battery transport vehicle 100 can be used to transport other goods, thereby improving the applicability of the battery transport vehicle 100.

[0143] In some embodiments, the battery device 200 for powering the battery transporter 100 can be installed in one of the mounting spaces 125 of the battery bracket 12, so that there is no need to set other brackets in the battery transporter 100 to fix the battery device 200 of the battery transporter 100 itself. Of course, other installation methods can also be used to fix the battery device 200 of the battery transporter 100 itself. In addition, the battery device 200 carried in the battery bracket 12 of the battery transporter 100 can also be used as a backup battery for the battery transporter 100 to increase the cruising range of the battery transporter 100.

[0144] Please refer to Figures 6 to 8 According to some embodiments of the present application, the battery holder 12 further includes a cover structure 121, which covers at least a portion of the mounting space 125 to at least shield the region where the interface structure 202 of the battery device 200 in the mounting space 125 is located.

In some embodiments, the interface structure 202 also includes a water connection structure 2022, which is used to connect the battery device 200 to the liquid cooling system. In this embodiment, the battery bracket 12 includes a cover structure 121, which is arranged above the mounting space 125, and can be arranged to cover the entire area of ​​the mounting space 125, or only a part of the mounting space 125; when the battery device 200 is arranged in the mounting space 125, the cover structure 121 can at least shield the interface structure 202 of the battery device 200, thereby protecting the interface structure 202 of the battery device 200, avoiding the interface structure 202 of the battery device 200 from being damaged by collision, and avoiding foreign matter from entering the interface structure 202 of the battery device 200.

[0146] Please refer to Figure 8According to some embodiments of the present application, the cover structure 121 includes a cover body 1211 and a connector assembly 1212. The cover body 1211 is disposed in the mounting space 125, and the connector assembly 1212 is disposed in the cover body 1211.

[0147] In this embodiment, the cover structure 121 includes a cover body 1211 as a base, and the cover body 1211 can be set above the entire mounting space 125, or can be set to cover a partial area of ​​the mounting space 125. The connector assembly 1212 includes at least an electrical connector 1213, and the electrical connector 1213 is used to connect with the electrical connection structure 2021 of the battery device 200; when the battery device 200 is also provided with a water connection structure 2022, the connector assembly 1212 can also include a water connector 1214 for connecting with the water connection structure 2022. The connector component 1212 is disposed on the cover body 1211. The connector component 1212 can be disposed on the side of the cover body 1211 facing the mounting space 125, or the connector component 1212 can be passed through the cover body 1211 along the height direction of the battery transporter 100 (i.e., the third direction Z in the figure), or the connector component 1212 can be disposed on the side of the cover body 1211 facing away from the mounting space 125, and a corresponding avoidance opening is disposed on the cover body 1211 opposite to the connector component 1212, so that when the battery device 200 is disposed in the mounting space 125, the interface structure 202 of the battery device 200 can pass through the avoidance opening and dock with the connector component 1212.

[0148] By adopting the above manner, when the battery device 200 is disposed in the mounting space 125 , the interface structure 202 of the battery device 200 is adapted to be connected with the connecting assembly, which can better protect the interface structure 202 of the battery device 200 .

[0149] Optionally, the connector assembly 1212 can adopt a connection structure used in an electrical device to connect a battery device 200. In this case, the connector assembly 1212 also has a connection end for connecting a cable and / or a water pipe, and the connection end is located outside the mounting space 125. For the mounting space 125 used to place the transported battery device 200, it is not necessary to connect the cable and the water pipe on the connector assembly 1212 corresponding to the mounting space 125. In some embodiments, the battery device 200 in part of the mounting space 125 can be used to provide power to the battery transporter 100. In this case, the connector assembly 1212 on the mounting space 125 can be used to connect the cable and the water pipe in the battery transporter 100, so that the battery device 200 in the mounting space 125 can be connected to the circuit and liquid cooling system in the battery transporter 100 through the connector assembly 1212.

[0150] Please refer to Figure 7 and Figure 8 According to some embodiments of the present application, the battery holder 12 further includes a blocking mechanism 122, and the blocking mechanism 122 is used to block the interface end of the connector assembly 1212 when the mounting space 125 is in an empty state.

[0151] In this embodiment, the interface end of the connector assembly 1212 refers to the end of the connector assembly 1212 used to dock with the interface structure 202 of the battery device 200, and the interface end is arranged toward the mounting space 125. The blocking mechanism 122 can be set as a cover, a sealing plug or other blocking member. Optionally, the blocking mechanism 122 can be manually operated to block the interface end of the connector assembly 1212, or removed from the interface end to open the interface end circuit; a driving component 1221 can also be set in the blocking mechanism 122 to drive the blocking member to move, so that the blocking member blocks or opens the interface end of the connector assembly 1212.

[0152] By setting up the blocking mechanism 122, when the battery device 200 is not installed in the mounting space 125, that is, when the mounting space 125 is in a vacant state, the blocking mechanism 122 can be used to block the interface end of the connector assembly 1212, thereby preventing rainwater, mud or other foreign matter from entering the interface end of the connector assembly 1212, so as to avoid damage to the interface structure 202 of the battery device 200 when the battery device 200 is installed in the mounting space 125.
