Description

Technical Field

[0001] The present invention relates to the technical field of battery replacement for electric vehicles, and in particular to an electric control box, shuttle-type battery pack replacement equipment and a battery replacement station. Background Art

[0002] In order to protect the electric control module connected to the shuttle-type battery pack replacement equipment and provide a housing space for the electric control module, the electric control module needs to be set in the electric control box of the shuttle-type battery pack replacement equipment. In the prior art, the electric control box is generally independently set in a position close to the battery pack replacement equipment in the battery swap station, and all cables are connected to the battery pack replacement equipment by the electric control box. In addition, since the battery pack replacement equipment needs to move back and forth, all cables need to be reserved with sufficient length, and all cables must be protected by a drag chain. Due to the large number of cables, the space occupied by the drag chain is also large, so the overall volume of the battery pack replacement equipment is also large. In addition, the electric control module often generates heat in the working state. In order to ensure the normal operation of the electric control module, the electric control box needs to dissipate heat. The existing technology usually opens heat dissipation holes in the electric control box, but this passive heat dissipation form has a very limited heat dissipation effect on the electric control module and cannot cool the electric control module well. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the defects in the prior art that the heat dissipation capacity of the electric control box is limited and the electric control box is set independently of the battery pack replacement equipment, resulting in a larger overall volume of the battery pack replacement equipment, and to provide an electric control box, a shuttle battery pack replacement equipment and a battery replacement station.

[0004] The present invention solves the above technical problems through the following technical solutions:

[0005] An electric control box comprises a box body and an electric control module, wherein the box body is used to be set on a shuttle-type battery pack replacement device, and the electric control module is set in a accommodating space inside the box body; the electric control box also comprises a heat dissipation fan, an air inlet and an air outlet are opened on the surface of the box body, and the heat dissipation fan is respectively set on the air inlet and the air outlet; the air inlet and the air outlet are both connected to the accommodating space, and in the accommodating space, an air flow path is formed between the air inlet and the air outlet; the setting position of the electric control module in the accommodating space is located on the air flow path, and the setting position of the electric control module is staggered with the opening direction of the air inlet and the air outlet.

[0006] In this solution, by providing an air inlet and an air outlet on the box body, and installing heat dissipation fans on both the air inlet and the air outlet, the heat dissipation fans are used to blow air inwards and exhaust air outwards, so that the outside air can enter the accommodation space from the air inlet and flow out from the air outlet to form an air flow path. Further, by arranging the electronic control module on the air flow path, the air flow speed around the electronic control module is enhanced, so that the generated heat can be carried away by the flowing air. Thus, the electronic control box can actively cool the electronic control module through the heat dissipation fans, and the heat dissipation effect is better.

[0007] Furthermore, the electronic control module is often connected with numerous cables. By staggering the installation position of the electronic control module from the opening directions of the air inlet and the air outlet, it is possible to prevent the electronic control module itself and the cables around it from obstructing the air flow at the air inlet and the air outlet. Instead, the air can flow more smoothly in the accommodation space, further improving the heat dissipation effect of the electronic control box.

[0008] In addition, since the box body of the electronic control box is installed on the shuttle-type battery pack replacement device, the distance between the two is shortened, and the length of the cable originally used to connect the electronic control box to the battery pack replacement device is also shortened. Moreover, the cable carrier no longer needs to support and protect this section of the cable. Therefore, a cable carrier with a smaller specification can be selected, reducing the occupied space of the cable carrier, and further reducing the overall volume of the shuttle-type battery pack replacement device, making the overall structure more lightweight.

[0009] Preferably, the box body includes a first side wall; both the air inlet and the air outlet are opened on the first side wall, and along the extending direction of the first side wall, the air inlet and the air outlet are spaced apart by a predetermined distance; along the extending direction of the first side wall, the electronic control module is located between the air inlet and the air outlet.

[0010] In this solution, both the air inlet and the air outlet are opened on the same side wall, which is convenient for checking the operating conditions of the heat dissipation fans from the same side; the air inlet and the air outlet are spaced apart by a predetermined distance, providing sufficient installation distance for the setting of the electronic control module and sufficient flowing distance for the air flow. The electronic control module is arranged between the air inlet and the air outlet, and the air flow can fully contact the electronic control module and carry away the heat.

[0011] Preferably, the box body further includes a wire inlet end and a wire outlet end; the wire inlet end is located on the side of the air inlet away from the electronic control module, and the wire outlet end is located on the side of the air outlet away from the electronic control module; or, the wire inlet end is located on the side of the air outlet away from the electronic control module, and the wire outlet end is located on the side of the air inlet away from the electronic control module.

[0012] In this solution, the inlet end is used to introduce the cable into the electric control box and electrically connect it to the electric control module, and the outlet end is used to lead out the cable electrically connected to the electric control module from the electric control box; the inlet end is located on the side of the air inlet away from the electric control module, that is, the air inlet is located between the inlet end and the electric control module, so that the air inlet avoids the inlet end and the electric control module where the cables are relatively concentrated, which is conducive to the smooth flow of air; similarly, the outlet end is located on the side of the air outlet away from the electric control module, the air outlet is located between the outlet end and the electric control module, and the air outlet also avoids the outlet end and the electric control module where the cables are relatively concentrated.

[0013] In addition, according to the actual setting requirements, the relative positions between the air inlet, the air outlet and the inlet end, the outlet end can be swapped. That is, the inlet end can also be located on the side of the air outlet away from the electric control module, so that the air outlet is arranged between the inlet end and the electric control module, and the air inlet is arranged between the outlet end and the electric control module.

[0014] Preferably, the electric control box further includes a mounting frame; the cooling fan is mounted on the air inlet and the air outlet through the mounting frame.

[0015] In this solution, the mounting frame provides a mounting base for the cooling fan at the air inlet and the air outlet, so that the cooling fan can be stably fixed in the air inlet and the air outlet.

[0016] Preferably, a protective grille is provided on the side of the mounting frame facing away from the accommodation space; and / or, a protective net is provided on the side of the mounting frame facing the accommodation space.

[0017] In this solution, the side of the mounting frame facing away from the accommodation space, that is, the side located outside the box body, is provided with a protective grille to prevent foreign objects from entering the fan and affecting the normal operation of the fan; in addition, according to actual requirements, the direction of the air inlet or the air outlet can also be adjusted by adjusting the orientation of the grille.

[0018] The protective net provided on the side facing the accommodation space can prevent the cables or other devices in the accommodation space from accidentally falling into the cooling fan, resulting in cable damage or cooling fan failure, without affecting the passage of air flow.

[0019] A shuttle-type battery pack replacement device includes a device frame and the electric control box as described above; the electric control box is integrally connected to the device frame.

[0020] In this solution, the device frame of the shuttle-type battery pack replacement device is used for moving and positioning to complete the installation and replacement of the battery pack. The electric control box is connected to the device frame, and the electric control module required for the shuttle-type battery pack replacement device can be set in the electric control box according to the actual situation, and the movement and operation of the device frame can be regulated; and the shuttle-type battery pack replacement device including the above electric control box can effectively dissipate heat from the electric control module and maintain a good operating state.

[0021] In addition, since the electrical control box is connected to the equipment frame, the distance between the two is shortened, the length of the cable originally used to connect the electrical control box to the battery pack replacement equipment is also shortened, and the drag chain no longer needs to support and protect this section of the cable. Therefore, a smaller drag chain can be selected to reduce the space occupied by the drag chain, thereby reducing the overall volume of the shuttle battery pack replacement equipment and making the overall structure lighter.

[0022] Preferably, the shuttle-type battery pack replacement equipment is movably arranged along a first direction; the equipment frame includes a first frame parallel to the first direction; the electric control box is connected to the first frame, and the electric control box is located outside the equipment frame.

[0023] In the present solution, the electric control box is connected to the outside of the equipment frame and does not occupy the installation space inside the equipment frame. In addition, by connecting the electric control box to the first side frame in the equipment frame parallel to the moving direction of the shuttle battery pack replacement equipment, the overall length of the shuttle battery pack replacement equipment can be avoided from being further increased due to the installation of the electric control box, thereby avoiding the increase in the length of the shuttle battery pack replacement equipment and causing the length of the battery swap station using it to increase, thereby effectively saving space.

[0024] Preferably, the box body includes a first side wall and a second side wall that are arranged opposite to each other; the second side wall faces the first frame and is connected to the first frame; the air inlet and the air outlet are both opened on the first side wall.

[0025] In the present solution, through the above-mentioned structural form, the first side wall is located on the side of the box body away from the equipment frame, and the air inlet and the air outlet are opened on the first side wall. On the one hand, the air inlet and the air outlet are not blocked by the equipment frame, and the air flow is smoother. On the other hand, the loading and unloading of the heat dissipation fan will not be interfered with by the equipment frame. When the heat dissipation fan needs to be repaired and replaced, the heat dissipation fan can be removed from the second side wall, which is more convenient.

[0026] Preferably, the accommodating space includes a connected first part and two second parts; along the first direction, the two second parts are respectively located on both sides of the first part; relative to the two second parts, the first part protrudes toward the first frame, and a clearance space is formed between the two second parts and the first frame for respectively accommodating the running wheels of the shuttle-type battery pack replacement equipment; the electronic control module is arranged in the first part; the opening positions of the air inlet and the air outlet are respectively located in the two second parts.

[0027] In this solution, the volume and width of the electric control box are very small due to the space requirements around the shuttle battery pack replacement equipment. However, through the above-mentioned structural form, the overall structure of the control box is in the shape of a "convex" character. The clearance space formed between the second part and the first frame can avoid the running wheels extending outside the equipment frame, and the first part protrudes toward the first frame, which increases the volume of the first part as much as possible and improves the overall space utilization of the control box. Furthermore, since the first part protrudes toward the first frame and has a larger width, the electric control module is arranged in the first part for easy loading and unloading and wiring; the air inlet and the air outlet are arranged in the second part on both sides of the first part to avoid the electric control module itself and the cables around it from hindering the air flow at the air inlet and the air outlet, and the layout is reasonable.

[0028] A battery swap station includes the shuttle battery pack replacement equipment as described above.

[0029] The positive and progressive effects of the present invention are:

[0030] In the present invention, an air inlet and an air outlet are provided on the box body, and a heat dissipation fan is provided on both the air inlet and the air outlet, and the heat dissipation fan is used to blow air inward and exhaust air outward, so that the outside air can enter the accommodating space from the air inlet and flow out from the air outlet to form an air flow path. Furthermore, by arranging the electric control module on the flow path of the air flow, the air flow speed around the electric control module is increased, so that the generated heat can be taken away by the flowing air. As a result, the electric control box can actively cool the electric control module through the heat dissipation fan, and the heat dissipation effect is better.

[0031] Furthermore, the electronic control module is often connected to many cables. By staggering the setting position of the electronic control module with the opening direction of the air inlet and the air outlet, the electronic control module itself and the cables around it can be prevented from obstructing the air flow at the air inlet and the air outlet. Instead, the air can flow more smoothly in the accommodating space, further improving the heat dissipation effect of the electronic control box.

[0032] In addition, since the body of the electric control box is set on the shuttle-type battery pack replacement equipment, the distance between the two is shortened, the length of the cable originally used to connect the electric control box to the battery pack replacement equipment is also shortened, and the drag chain no longer needs to support and protect this section of the cable. Therefore, a smaller drag chain can be selected to reduce the space occupied by the drag chain, thereby reducing the overall volume of the shuttle-type battery pack replacement equipment and making the overall structure lighter.

[0063] The present invention will be more clearly and completely described below through embodiments in conjunction with the drawings.

[0064] This embodiment discloses a battery swapping station, which includes a shuttle-type battery pack replacement device.

[0065] The shuttle-type battery pack replacement device is used to move on a predetermined track or route in the battery swapping station and complete the replacement of the vehicle battery.

[0066] As Figure 1 and Figure 2 shown, the shuttle-type battery pack replacement device in this embodiment includes a device frame 500 and an electric control box 100, and the electric control box 100 is integrally connected to the device frame 500.

[0067] As Figure 2 and Figure 3 shown ( Figure 3 In order to show the internal structure of the electric control box 100, the top of the electric control box 100 is omitted), the electric control box 100 includes a box body 200, an electric control module 300 and a heat dissipation fan 400. The electric control module 300 is arranged in the accommodation space 210 inside the box body 200. An air inlet 213 and an air outlet 214 are formed on the surface of the box body 200. The heat dissipation fans 400 are respectively arranged on the air inlet 213 and the air outlet 214; both the air inlet 213 and the air outlet 214 are communicated with the accommodation space 210. An air flow path is formed between the air inlet 213 and the air outlet 214 in the accommodation space 210; the setting position of the electric control module 300 in the accommodation space 210 is located on the air flow path, and the setting position of the electric control module 300 is staggered from the opening directions of the air inlet 213 and the air outlet 214; the box body 200 is used to be arranged on the shuttle-type battery pack replacement device. Specifically, the box body 200 is connected to the device frame 500.

[0068] By providing an air inlet 213 and an air outlet 214 on the cabinet 200 and installing cooling fans 400 on both the air inlet 213 and the air outlet 214, the cooling fans 400 are used to blow air inwards and exhaust air outwards, enabling outside air to enter the accommodation space 210 from the air inlet 213 and flow out from the air outlet 214, so as to form an air flow path. Further, by arranging the electronic control module 300 on the air flow path, the air flow speed around the electronic control module 300 is enhanced, allowing the generated heat to be carried away by the flowing air. Thus, the electric control box 100 can actively cool the electronic control module 300 through the cooling fans 400, achieving a better heat dissipation effect and enabling the electronic control module 300 to maintain a good operating state. In addition, the electronic control module 300 is often connected to numerous cables. By staggering the installation position of the electronic control module 300 from the opening directions of the air inlet 213 and the air outlet 214, it can be avoided that the electronic control module 300 itself and the cables around it obstruct the air flow at the air inlet 213 and the air outlet 214. Instead, the air flow in the accommodation space 210 can be made smoother, further improving the heat dissipation effect of the electric control box 100.

[0069] In this embodiment, the air inlet 213 and the air outlet 214 are opened on the same side wall of the cabinet 200, and along the extending direction of this side wall, the air inlet 213 and the air outlet 214 are spaced apart by a predetermined distance; along the extending direction of this side wall, the electronic control module 300 is located between the air inlet 213 and the air outlet 214.

[0070] By opening the air inlet 213 and the air outlet 214 on the same side wall, it is convenient to view and check the operating conditions of the cooling fans 400 from the same side; the air inlet 213 and the air outlet 214 are spaced apart by a predetermined distance, providing sufficient installation distance for the setting of the electronic control module 300 and also sufficient flow distance for the air flow. The electronic control module 300 is arranged between the air inlet 213 and the air outlet 214, enabling the air flow to fully contact the electronic control module 300 and carry away the heat.

[0071] Further, the cabinet 200 further includes a wire inlet end 215 and a wire outlet end 216. In this embodiment, the wire inlet end 215 is located on the side of the air inlet 213 away from the electronic control module 300, and the wire outlet end 216 is located on the side of the air outlet 214 away from the electronic control module 300.

[0072] The inlet terminal 215 is used to introduce a cable into the electric control box 100 and is electrically connected to the electric control module 300. The outlet terminal 216 is used to lead out the cable electrically connected to the electric control module 300 from the electric control box 100. The inlet terminal 215 is located on the side of the air inlet 213 away from the electric control module 300, that is, the air inlet 213 is located between the inlet terminal 215 and the electric control module 300. Thus, the air inlet 213 avoids the inlet terminal 215 and the electric control module 300 where the cables are relatively concentrated, which is conducive to the smooth flow of air. Similarly, the outlet terminal 216 is located on the side of the air outlet 214 away from the electric control module 300, and the air outlet 214 is located between the outlet terminal 216 and the electric control module 300. The air outlet 214 also avoids the outlet terminal 216 and the electric control module 300 where the cables are relatively concentrated.

[0073] In other optional embodiments, according to actual setting requirements, the relative positions between the air inlet 213, the air outlet 214 and the inlet terminal 215, the outlet terminal 216 can be swapped. That is, the inlet terminal 215 can also be located on the side of the air outlet 214 away from the electric control module 300, and the outlet terminal 216 is located on the side of the air inlet 213 away from the electric control module 300, so that the air outlet 214 is arranged between the inlet terminal 215 and the electric control module 300, and the air inlet 213 is arranged between the outlet terminal 216 and the electric control module 300.

[0074] Furthermore, as Figure 3 and Figure 4 shown, the electric control box 100 further includes a mounting frame 410. The cooling fan 400 is installed on the air inlet 213 and the air outlet 214 through the mounting frame 410. The mounting frame 410 provides a mounting base for the cooling fan 400 on the air inlet 213 and the air outlet 214, enabling the cooling fan 400 to be stably fixed in the air inlet 213 and the air outlet 214.

[0075] In this embodiment, the cooling fan 400 is in the form of an axial flow fan. The components of the cooling fan 400, such as the central shaft, blades, built-in motor, etc., are all arranged inside the mounting frame 410. Both ends of the central shaft are connected to the mounting frame 410, and the blades rotate around the circumference of the central shaft. The cooling fans 400 at the air inlet 213 and the air outlet 214 achieve one blowing air into the accommodation space 210 and the other exhausting air out of the accommodation space 210 by making the rotation directions of the blades opposite.

[0076] The operation of the cooling fan 400 depends on electric drive. The cooling fan 400 is electrically connected to the electric control module 300 through a cable, enabling the electric control module 300 to control the operation of the cooling fan 400 and supply power to it.

[0077] Specifically, a protective grille 411 is provided on the side of the mounting frame 410 facing away from the accommodation space 210, and a protective net 412 is provided on the side of the mounting frame 410 facing the accommodation space 210.

[0078] On the side of the installation frame 410 facing away from the accommodation space 210, that is, on the side located outside the box body 200, a protective grille 411 is provided to prevent foreign objects from entering the fan and affecting the normal operation of the fan. In addition, according to actual needs, the direction of air intake or exhaust can also be adjusted by adjusting the orientation of the grille. A protective net 412 provided on the side facing the accommodation space 210 can prevent the cables or other devices in the accommodation space 210 from accidentally falling into the cooling fan 400 without affecting the passage of air flow, resulting in cable damage or failure of the cooling fan 400.

[0079] In this embodiment, it is selected to set both the protective grille 411 and the protective net 412. In other alternative embodiments, the protective grille 411 or the protective net 412 can also be selectively set according to actual situations.

[0080] In this embodiment, the number of air inlets 213 and air outlets 214 is one each. In other alternative embodiments, when the installation space permits and there is a definite need, the number of air inlets 213 and air outlets 214 can both be set to be greater than one, and the number of cooling fans 400 is increased accordingly; the specific installation position of the cooling fans 400 can also have other choices different from this embodiment; in addition, the specific structural form of the cooling fans 400 can also be selected as other forms such as centrifugal fans.

[0081] Furthermore, the shuttle - type battery pack replacement device is movably arranged along the first direction X; the device frame 500 includes a first side frame 510 parallel to the first direction X; the electric control box 100 is connected to the first side frame 510, and the electric control box 100 is located outside the device frame 500.

[0082] The electric control box 100 is connected to the outside of the device frame 500 and does not occupy the installation space inside the device frame 500. In addition, by connecting the electric control box 100 to the first side frame 510 in the device frame 500 that is parallel to the moving direction of the shuttle - type battery pack replacement device, it is possible to avoid the overall length of the shuttle - type battery pack replacement device in the first direction X from further increasing due to the setting of the electric control box 100, and further avoid the increase in the length of the shuttle - type battery pack replacement device resulting in an increase in the length of the battery swapping station accommodating it, effectively saving space.

[0083] It should be noted that the "first direction X" is a direction set for the convenience of description of this embodiment. In practice, the "first direction X" is generally a direction in the horizontal plane, that is, the shuttle - type battery pack replacement device generally moves in the horizontal plane; however, the "first direction X" can also be a direction with a certain angle to the horizontal plane, forming a "ramp" form.

[0084] The shuttle battery pack replacement device in this embodiment relies on the running wheels 530 arranged on both sides of the device frame 500 to achieve movement. In other optional embodiments, the shuttle battery pack replacement device can also be moved by means of sliders and slide rails.

[0085] Specifically, the box body 200 includes a first side wall 220 and a second side wall 230 that are arranged opposite to each other; the second side wall 230 faces the first frame 510 and is connected to the first frame 510 ; the air inlet 213 and the air outlet 214 are both opened on the first side wall 220 .

[0086] Through the above-mentioned structural form, the first side wall 220 is located on the side of the box body 200 away from the equipment frame 500, and the air inlet 213 and the air outlet 214 are opened on the first side wall 220. On the one hand, the air inlet 213 and the air outlet 214 are not blocked by the equipment frame 500, and the air flow is smoother. On the other hand, the loading and unloading of the heat dissipation fan 400 will not be interfered by the equipment frame 500. When the heat dissipation fan 400 needs to be repaired and replaced, the heat dissipation fan 400 can be removed from the side of the second side wall 230, which is more convenient.

[0087] Furthermore, the accommodating space 210 includes a connected first part 211 and two second parts 212; along the first direction X, the two second parts 212 are respectively located on both sides of the first part 211; relative to the two second parts 212, the first part 211 protrudes toward the first frame 510, and a clearance space 520 is formed between the two second parts 212 and the first frame 510 for respectively accommodating the walking wheels 530 of the shuttle-type battery pack replacement equipment; the electronic control module 300 is arranged in the first part 211; the opening positions of the air inlet 213 and the air outlet 214 are respectively located in the two second parts 212.

[0088] Limited by the space requirements around the shuttle battery pack replacement equipment, the volume and width of the electric control box 100 are very small. Through the above-mentioned structural form, the overall structure of the control box is in the shape of a "convex" character. The clearance space 520 formed between the second part 212 and the first frame 510 can avoid the running wheels 530 extending outside the equipment frame 500, and the first part 211 protrudes toward the first frame 510, which increases the volume of the first part 211 as much as possible and improves the overall space utilization of the control box. In addition, since the first part 211 protrudes toward the first frame 510 and has a large width, the electric control module 300 is arranged in the first part 211 for easy loading and unloading and wiring; the air inlet 213 and the air outlet 214 are arranged in the second part 212 on both sides of the first part 211 to prevent the electric control module 300 itself and the cables around it from obstructing the air flow at the air inlet 213 and the air outlet 214, and the layout is reasonable.

[0089] Furthermore, in this embodiment, the second side wall 230 is spaced a predetermined distance from the first frame 510 to provide installation space for external devices such as the running wheels 530 disposed on the side of the equipment frame 500 facing the electric control box 100 (ie, the first frame 510).

[0090] In order to achieve the connection between the second side wall 230 and the first frame 510, the present embodiment selects to set a plurality of connecting plates 601, so that the two ends of the connecting plates 601 are respectively connected to the first frame 510 and the second side wall 230. The connecting plates 601 can be welded to the first frame 510 and the second side wall 230, or can be detachably connected to the first frame 510 and the second side wall 230 by screws.

[0091] In this embodiment, the device frame 500 does not simply refer to a frame structure, but refers to a device that integrates functions such as walking, lifting, plugging and unplugging batteries, and carrying batteries. The realization of these functions requires specific structures. For example, in order to realize the lifting function, a lifter needs to be installed in the device frame 500, and a drive motor is needed to drive the lifter. In this embodiment, for the sake of simplicity, electrical components that realize specific functions such as drive motors and sensors are collectively referred to as electric control components 540, and are described in detail in the following sections. Figure 2 In the figure, only one driving motor is exemplarily indicated as the electric control element 540 for illustration (in order to facilitate the display of the electric control element 540 and the electric control module 300, Figure 2 The top of the portion of the equipment frame 500 that accommodates the electric control element 540 and the top of the electric control box 100 are omitted).

[0092] The electric control module 300 is a "central" device that drives the device frame 500 to execute various instructions. The electric control module 300 is electrically connected to the electric control element 540 through a cable and transmits operating instructions to the electric control element 540 and provides power to it to control the operation of the electric control element 540. The specific structure of the electric control module 300 that transmits operating instructions and provides power belongs to the prior art and will not be described in detail.

[0093] Of course, the operation of the electric control module 300 itself also requires power supply. The power cable of the battery swap station is introduced into the electric control box 100 through the drag chain 603 arranged at the incoming line end 215 and is electrically connected to the electric control module 300.

[0094] The cable outlet 216 of the electric control box 100 is used to lead the cable connected between the electric control module 300 and the electric control element 540 out of the electric control box 100 , so that the cable can be connected to the electric control element 540 in the equipment frame 500 .

[0095] On the premise that the electrical control box 100 is spaced apart from the equipment frame 500 by a predetermined distance, in this embodiment, the wire outlet end 216 is opened on the second side wall 230, and a wire conduit 602 is provided. The two ends of the wire conduit 602 are respectively connected to the second side wall 230 and the first frame 510, and are respectively communicated with the wire outlet end 216 and the interior of the equipment frame 500.

[0096] The setting of the wire conduit 602 provides protection for the cables extending from the electrical control box 100, preventing the cables from being easily damaged when exposed. Moreover, the second side wall 230 faces the first frame 510, with the shortest distance, so the length of the wire conduit 602 is also reduced, saving costs.

[0097] Thus, the electrical control box 100 and the equipment frame 500 are integrally connected. By arranging the electrical control box 100 equipped with the electrical control module 300 on the shuttle-type battery pack replacement device, the distance between the electrical control module 300 and the electrical control components 540 is shortened, enabling the lengths of the numerous cables connecting the electrical control module 300 and the electrical control components 540 to be shortened, thereby reducing cable costs. At the same time, since the electrical control box 100 equipped with the electrical control module 300 is arranged on the shuttle-type battery pack replacement device, the numerous cables between the electrical control module 300 and the electrical control components 540 do not require the cable carrier 603 for support and protection and do not need to pass through the cable carrier 603. This allows the cable carrier 603 to only introduce a few cables such as power cables into the electrical control box 100 to connect with the electrical control module 300. As a result, the number of cables to be accommodated in the cable carrier 603 is reduced, which not only alleviates the friction and extrusion between the cables in the cable carrier 603 but also allows a smaller-sized cable carrier 603 to be selected, further saving costs and reducing the occupied space of the cable carrier 603. Furthermore, the overall volume of the shuttle-type battery pack replacement device can be reduced, and the overall structure is more lightweight.

[0098] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the conventional positional relationships when the shuttle-type battery pack replacement device is installed and placed in the conventional usage manner.

[0099] Although the specific implementation manners of the present invention have been described above, those skilled in the art should understand that this is only for illustration purposes. The protection scope of the present invention is defined by the appended claims. Without departing from the principles and essence of the present invention, those skilled in the art can make various changes or modifications to these implementation manners, but these changes and modifications all fall within the protection scope of the present invention.
