Description

Technical Field

[0001] This invention belongs to the field of new energy battery swapping technology, and more specifically, relates to an on-board battery swapping device and a new energy engineering vehicle. Background Technology

[0002] Electrified engineering equipment is gradually replacing older internal combustion engine engineering equipment. However, engineering machinery such as loaders and excavators consume a great deal of energy due to their long-term heavy-duty operations. If the power batteries are not extended or replaced, it will seriously affect the normal operation of new energy engineering vehicles. Since charging the power batteries takes a long time and affects the work cycle, battery swapping has become an important means to effectively solve the range anxiety problem of electrified engineering equipment.

[0003] However, currently, battery swapping for engineering vehicles such as loaders and excavators usually needs to be carried out in battery swapping stations. This requires not only the construction of battery swapping stations but also the configuration of dedicated battery swapping equipment, which accounts for a considerable proportion of the investment and operating costs of new energy loaders, excavators, and other engineering vehicles.

[0004] While this battery swapping model is suitable for scenarios with clusters of new energy engineering vehicles, it would be very costly to build battery swapping stations for scenarios with a small number of such vehicles that require continuous operation. Furthermore, each battery swap needs to be performed within the station, which complicates the battery swapping operation for new energy engineering vehicles and increases time and labor costs.

[0005] To reduce battery swapping costs for new energy engineering vehicles, some users with a limited number of such vehicles are using cranes to replace the batteries. However, most engineering vehicles require fieldwork, and the limited working environment makes it impossible to use large machinery such as cranes. This not only severely impacts the normal operation of new energy engineering vehicles but also significantly hinders their promotion. Furthermore, the need to carry batteries in new energy engineering vehicles increases the number of components on the vehicle body. How to rationally arrange the battery placement to facilitate battery replacement, and how to more effectively distribute hydraulic and power equipment on the vehicle, are urgent problems that need to be solved. Summary of the Invention

[0006] The purpose of this invention is to provide an on-board battery swapping device and a new energy engineering vehicle, aiming to solve the problems of limited and high cost of replacing power batteries in existing new energy engineering vehicles, which seriously affects the promotion and use of new energy engineering vehicles, as well as the large number of components required for installation in new energy engineering vehicles and the lack of compact and reasonable layout.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0008] Firstly, an on-board battery swapping device is provided, comprising:

[0009] A chassis assembly connected to a vehicle body, the chassis assembly including a robotic arm mounting frame, and an operator cab mounting frame and a power equipment mounting frame respectively disposed on both sides of the robotic arm mounting frame in the left and right directions;

[0010] A fixing component is located on the rear side of the robotic arm mounting frame;

[0011] A support assembly is disposed on the rear side of the fixed assembly and slidably connected to the fixed assembly in the front-rear direction. The support assembly is also rotatably connected to the fixed assembly about a first axis, which is set at an angle to the front-rear direction. The power battery is installed on the support assembly. When the support assembly slides to its farthest rearward end, the support assembly flips downward about the first axis.

[0012] A hoisting assembly is rotatably connected to the fixed assembly, and the hoisting assembly is used to hoist the power battery.

[0013] In conjunction with the first aspect, in one possible implementation, the robotic arm mounting frame includes robotic arm mounting positions, rotary support mounting positions, drive motor mounting positions, and control valve mounting positions distributed from front to back, with the fixing component located behind the control valve mounting position.

[0014] In conjunction with the first aspect, in one possible implementation, the robotic arm mounting frame includes a support base and two mounting plates located on the left and right sides of the support base, respectively. The two mounting plates are respectively provided with corresponding robotic arm mounting holes, which form the robotic arm mounting positions.

[0015] In conjunction with the first aspect, in one possible implementation, the slewing support mounting position, the drive motor mounting position, and the control valve mounting position are all located on the support base. The support base has a first clearance hole, a second clearance hole, and a third clearance hole, wherein the first clearance hole corresponds to the slewing support mounting position, the second clearance hole corresponds to the drive motor mounting position, and the third clearance hole corresponds to the control valve mounting position.

[0016] In conjunction with the first aspect, in one possible implementation, the fixing component includes a plurality of fixing members spaced apart in the left-right direction, the plurality of fixing members being respectively connected to the vehicle frame, and the support component being slidably connected to the plurality of fixing members in the front-rear direction.

[0017] In conjunction with the first aspect, in one possible implementation, the fixing component has a groove along the front-to-back direction, a limiting rod is provided within the groove, the axis of the limiting rod is parallel to the left-to-right direction, and the support component includes:

[0018] The support mechanism includes a support platform slidably connected to the vehicle frame in a front-rear direction and a sliding member connected to the rear side of the support platform. The sliding member is slidably disposed within a groove, and a limiting groove is formed in the front-rear direction of the sliding member. A limiting rod is inserted into the limiting groove. When the sliding member slides to its farthest rearward end, the sliding member flips downward around the limiting rod.

[0019] A drive mechanism is rotatably connected to the fixed component, and the drive end of the drive mechanism is rotatably connected to the support platform for driving the support platform to slide in the front-back direction.

[0020] In conjunction with the first aspect, in one possible implementation, the drive mechanism includes:

[0021] A telescopic actuator, rotatably connected to the fixed assembly; and

[0022] A push rod is connected to the support platform and extends in the left-right direction. The telescopic end of the telescopic actuator is rotatably connected to the push rod.

[0023] In conjunction with the first aspect, in one possible implementation, the support component further includes a locking mechanism connected to both the fixing component and the drive mechanism, the locking mechanism comprising:

[0024] A guide member, connected to the fixing assembly, the guide member being arranged in a left-right direction; and

[0025] The locking component has a locking groove along the front-to-back direction. The guide component is inserted into the locking groove. The locking component is also rotatably connected to the push rod. When the support platform is flipped down to the lowest point, the guide component is engaged with the outer edge of the locking groove.

[0026] In conjunction with the first aspect, in one possible implementation, the hoisting assembly includes:

[0027] A hoisting actuator, rotatably connected to the fixed assembly, wherein the hoisting actuator is a telescopic component; and

[0028] The hoisting mechanism is rotatably connected to the fixed component, and is also rotatably connected to the drive end of the hoisting driver. The hoisting mechanism is used to hoist the power battery.

[0029] The beneficial effects of the vehicle-mounted battery swapping device provided by this invention are as follows: Compared with the prior art, the robotic arm mounting frame, operator cab mounting frame, and power equipment mounting frame of the vehicle-mounted battery swapping device of this invention are connected to form an integral vehicle frame assembly, which is then installed on the vehicle body. The vehicle frame assembly provides support and installation positions for the fixing assembly, support assembly, and lifting assembly. Simultaneously, the robotic arm, operator cab, and power equipment can all be connected to the vehicle body through the vehicle frame assembly. The vehicle frame assembly not only provides installation positions for the aforementioned components but also achieves overall planning of the installation area, making the overall vehicle layout more rational and compact. When the power battery needs to be replaced, the support assembly slides towards the rear of the fixing assembly. After the support assembly slides to its farthest point, it flips downwards under gravity, causing the power battery connected to the support assembly to flip downwards simultaneously. After the support assembly flips downwards to the designated position, the lifting assembly removes the vehicle-mounted power battery. Then, the lifting assembly lifts the new power battery to the connection with the support assembly, after which the support assembly rotates upwards and slides back to its original position in the front-rear direction. This invention eliminates the need for external hoisting equipment for battery replacement, enabling more convenient and faster battery swapping at field sites and ensuring the continuous range of new energy engineering vehicles. Furthermore, it eliminates the need for dedicated battery swapping stations, reducing costs and facilitating the widespread adoption of new energy engineering vehicles.

[0030] Secondly, embodiments of the present invention also provide a new energy engineering vehicle, including any of the on-board battery swapping devices described above.

[0031] The beneficial effects of the new energy engineering vehicle provided by the present invention are as follows: compared with the prior art, it adopts the above-mentioned vehicle-mounted battery swapping device, which has similar technical effects to the above-mentioned vehicle-mounted battery swapping device, and will not be described in detail here.

[0044] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

In the claims, description, and accompanying drawings of this invention, the terms "comprising," "having," and variations thereof are intended to mean "including but not limited to."

[0046] Please refer to the following: Figures 1 to 6 The present invention will now describe the vehicle-mounted battery swapping device and the new energy engineering vehicle provided. The vehicle-mounted battery swapping device includes a frame assembly 4, a fixing assembly 1, a support assembly 2, and a hoisting assembly 3. The frame assembly 4 is connected to the vehicle body and includes a robotic arm mounting frame 401, and an operator's cab mounting frame 402 and a power equipment mounting frame 403 respectively located on both sides of the robotic arm mounting frame 401 in the left and right directions. The fixing assembly 1 is located on the rear side of the robotic arm mounting frame 401. The support assembly 2 is located on the rear side of the fixing assembly 1 and is slidably connected to the fixing assembly 1 in the front-back direction. The support assembly 2 is also rotatably connected to the fixing assembly 1 around a first axis. The first axis is set at an angle to the front-back direction. The power battery is installed on the support assembly 2. When the support assembly 2 slides to its farthest point in the rear, the support assembly 2 flips downward around the first axis. The hoisting assembly 3 is rotatably connected to the fixing assembly 1 and is used to hoist the power battery.

[0047] The vehicle-mounted battery swapping device provided by this invention, compared with the prior art, has a frame assembly 4 formed by connecting the robotic arm mounting frame 401, the operator's cab mounting frame 402, and the power equipment mounting frame 403, and is installed on the vehicle body. The frame assembly 4 provides support and installation positions for the fixing assembly 1, the support assembly 2, and the lifting assembly 3. Simultaneously, the robotic arm, operator's cab, and power equipment can all be connected to the vehicle body through the frame assembly 4. The frame assembly 4 not only provides installation positions for the aforementioned components but also achieves overall planning of the installation area, making the overall vehicle layout more rational and compact. When the power battery needs to be replaced, the support assembly 2 slides to the rear of the fixing assembly 1. After the support assembly 2 slides to its farthest end, it flips downwards under gravity, causing the power battery connected to the support assembly 2 to flip downwards simultaneously. After the support assembly 2 flips downwards to the designated position, the lifting assembly 3 removes the vehicle-mounted power battery. Then, the lifting assembly 3 lifts the new power battery to connect with the support assembly 2, after which the support assembly 2 rotates upwards and slides back to its original position in the front-rear direction. This invention eliminates the need for external hoisting equipment for battery replacement, enabling more convenient and faster battery swapping at field sites and ensuring the continuous range of new energy engineering vehicles. Furthermore, it eliminates the need for dedicated battery swapping stations, reducing costs and facilitating the widespread adoption of new energy engineering vehicles.

[0048] It should be noted that when the operator's cab mounting bracket 402 is located on the left side of the robotic arm mounting bracket 401, the power equipment mounting bracket 403 is located on the right side of the robotic arm mounting bracket 401. Conversely, when the operator's cab mounting bracket 402 is located on the right side of the robotic arm mounting bracket 401, the power equipment mounting bracket 403 is located on the left side of the robotic arm mounting bracket 401. Both of these arrangements are acceptable and are not limited here.

[0049] In some embodiments, please refer to Figure 1 The robotic arm mounting frame 401 includes a robotic arm mounting position, a rotary support mounting position, a drive motor mounting position, and a control valve mounting position distributed from front to back. The fixing component 1 is located behind the control valve mounting position.

[0050] In this embodiment, the robotic arm is installed at the robotic arm mounting position, the slewing support is installed at the slewing support mounting position, the slewing motor is installed at the drive motor mounting position, and the hydraulic main valve is installed at the control valve mounting position. The above devices are distributed sequentially along the front-back direction to avoid mutual interference, making the layout on the robotic arm mounting frame 401 reasonable and neat.

[0051] It should be noted that the upper part of engineering vehicles such as excavators or loaders can rotate, and the rotary motor is used to drive the rotation of the upper part of the vehicle.

[0052] In some embodiments, please refer to Figure 1The robotic arm mounting frame 401 includes a support base 4011 and two mounting plates 4012 located on the left and right sides of the support base 4011, respectively. The two mounting plates 4012 are respectively provided with corresponding robotic arm mounting holes 4016, which form robotic arm mounting positions.

[0053] The robotic arm is mounted on the mounting plate 4012, and inserted into the robotic arm mounting hole 4016, achieving a rotatable connection with the mounting plate 4012. It operates under the action of a hydraulic actuator. Since the robotic arm requires multi-directional rotation during operation, the connection with the mounting plate 4012 prevents interference with the support base 4011, ensuring flexible operation of the robotic arm.

[0054] In some embodiments, please refer to Figure 1 The slewing support mounting position, the drive motor mounting position, and the control valve mounting position are all located on the support base 4011. The support base 4011 has a first clearance hole 4013, a second clearance hole 4014, and a third clearance hole 4015. The first clearance hole 4013 corresponds to the slewing support mounting position, the second clearance hole 4014 corresponds to the drive motor mounting position, and the third clearance hole 4015 corresponds to the control valve mounting position.

[0055] The design of the first clearance hole 4013, the second clearance hole 4014, and the third clearance hole 4015 can reduce the weight of the support base 4011, achieving overall vehicle lightweighting, and can also save materials and reduce costs. In addition, the connector 102 can also pass through the first clearance hole 4013 to connect the support base 4011 to the vehicle body, thereby fixing the frame assembly 4 to the vehicle body.

[0056] As one specific embodiment of the operator's cab mounting bracket 402, please refer to Figure 1 The operator's cab mounting frame 402 includes a cab mounting position 4021 and a cooling system mounting position 4022 distributed from front to rear. The cab is located at the front of the operator's cab mounting frame 402, which facilitates the driver's observation of the external situation and broadens the field of vision. The cooling system mounting position 4022 is used to install a radiator, which dissipates heat from the motor and the cab air conditioner.

[0057] As one specific embodiment of the power equipment mounting bracket 403, please refer to Figure 1 The power equipment mounting bracket 403 includes a powertrain mounting position 4031 and an oil tank mounting position 4032 distributed from front to back. Power equipment such as motors are located in the powertrain mounting position 4031, and the motor drives the main pump to deliver hydraulic oil to the main valve. The hydraulic oil tank and the hydraulic system cooling device are both located in the oil tank mounting position 4032.

[0058] In some embodiments, please refer to Figures 1 to 4The fixing component 1 includes a plurality of fixing members 101 spaced apart in the left-right direction. The plurality of fixing members 101 are respectively connected to the robotic arm mounting frame 401. The support component 2 is slidably connected to the plurality of fixing members 101 in the front-back direction.

[0059] In this embodiment, the support component 2 is slidably connected to multiple fixing parts 101, thereby increasing the contact area between the support component 2 and the fixing component 1 and improving the stability and firmness of the connection. Because the power battery is heavy, connection failure is likely to occur during the sliding and flipping of the support component 2 under its load. To prevent damage to the fixing parts 101 or the support component 2, multiple fixing parts 101 are connected to the support component 2 to ensure that the fixing parts 101 and the support component 2 are not damaged during replacement.

[0060] In some embodiments, please refer to Figure 1 and Figure 3 The fixing component 1 also includes a connector 102 connected to the plurality of fixing members 101.

[0061] The connector 102 connects multiple fasteners 101 to form an integral structure. Compared with the scheme where multiple fasteners 101 are set independently and have no connection with each other, this further increases the connection between the multiple fasteners 101 and the robotic arm mounting frame 401. At the same time, it can also avoid the problem of connection failure between the fasteners 101 and the support component 2 after being subjected to force.

[0062] In some embodiments, please refer to Figure 3 The fixed component 1 has a sliding groove 1011 along the front-back direction, and a limiting rod 103 is provided in the sliding groove 1011. The axis of the limiting rod 103 is parallel to the left-right direction. The support component 2 includes a support mechanism and a drive mechanism. The support mechanism includes a support platform 201 that is slidably connected to the robotic arm mounting frame 401 along the front-back direction and a sliding member 206 connected to the rear side of the support platform 201. The sliding member 206 is slidably disposed in the sliding groove 1011, and a limiting groove 2061 is provided in the sliding member 206 along the front-back direction. The limiting rod 103 is inserted in the limiting groove 2061. When the sliding member 206 slides to the farthest end away from the fixed component 1, the sliding member 206 flips downward around the limiting rod 103. The drive mechanism is rotatably connected to the fixed component 1, and the drive end of the drive mechanism is rotatably connected to the support platform 201 for driving the support platform 201 to slide along the front-back direction.

[0063] During normal use of the engineering vehicle, the sliding member 206 slides and approaches or overlaps with the fixed component 1 in the front-rear direction. When the power battery needs to be replaced, the sliding member 206 slides along the slide groove 1011 to the side away from the fixed component 1. When the sliding member 206 slides to the designated position, it flips downward until the limiting rod 103 engages with the edge of the limiting groove 2061. In this embodiment, the engagement of the limiting rod 103 with the edge of the limiting groove 2061 prevents the sliding member 206 from separating from the fixed component 1, thereby allowing the power battery to be removed by the lifting component 3. In this embodiment, the structural components limit the support platform 201 by the limiting rod 103 located in the slide groove 1011 and the limiting groove 2061 opened on the sliding member 206. This eliminates the need for a separate limiting structure, avoiding the need for a complex limiting structure that would occupy too much space in the robotic arm mounting frame 401, and does not affect the normal use of the engineering vehicle, thus contributing to the lightweighting of the entire vehicle.

[0064] Specifically, the limiting rod 103 is located on the side of the fixing component 1 near the support platform 201.

[0065] In some embodiments, please refer to Figure 6 The slider 206 has an arc-shaped clearance portion 2062 on the side near the fixed component 1, and the clearance portion 2062 is located at the top of the slider 206.

[0066] When the slider 206 flips downward, the side of the limit rod 103 that is away from the support platform 201 will rotate upward. The arc-shaped clearance part 2062 can avoid interference with other parts during flipping, and can also save materials and reduce costs.

[0067] Optionally, the slide 1011 can be formed on the side wall of the fixed component 1, communicating with the outside in the left-right direction. In this case, even without the clearance portion 2062, the sliding member 206 will not interfere with the fixed component 1 when it flips, but it may affect other components on the robotic arm mounting frame 401. The slide 1011 can also be formed in the middle of the fixed component 1 in the left-right direction, that is, the left and right sides of the slide 1011 are closed. In this case, without the clearance portion 2062, it will not interfere with the fixed component 1 when it flips. In addition, the fixed component 1 can also have the slide 1011 formed in the front-back direction, with the top and / or bottom of the slide 1011 closed. In this case, if the clearance portion 2062 is not provided, the sliding member 206 may interfere with the top of the fixed component 1 when it flips.

[0068] Optional, please refer to Figure 4 The fixing component 1 has a through groove 1011 along the front-back direction. The top and bottom of the groove 1011 are closed. On the side near the support component 2, the bottom of the fixing component 1 has a relief groove that communicates with the groove 1011 to prevent the sliding component 206 from interfering with the bottom of the groove 1011 when it flips.

[0069] In some embodiments, please refer to Figures 1 to 3 The driving mechanism includes a telescopic driver 202 and a push rod 203. The telescopic driver 202 is rotatably connected to the fixed component 1. The push rod 203 is connected to the support platform 201 and extends in the left and right direction. The telescopic end of the telescopic driver 202 is rotatably connected to the push rod 203.

[0070] The fixed end of the telescopic actuator 202 is rotatably connected to the fixed component 1. When it is necessary to control the support platform 201 to slide in the front-back direction, the telescopic actuator 202 extends, thereby pushing the support platform 201 to slide. After the support platform 201 slides to the designated position, it flips downward under the action of gravity. At this time, the drive mechanism rotates around the push rod 203 and the fixed component 1 respectively, avoiding interference with the flipping of the support platform 201. In this embodiment, there is no need for manual pushing of the support platform 201 to slide. The sliding of the support platform 201 is achieved by the telescopic actuator 202, which saves more manpower. Moreover, compared with the lead screw drive method, the solution in this embodiment avoids occupying too much space after the sliding member 206 is reset.

[0071] Optionally, the telescopic actuator 202 can be a hydraulic telescopic component or a pneumatic telescopic component.

[0072] In some embodiments, please refer to Figures 1 to 3 The support assembly 2 also includes a locking mechanism that is connected to the fixed assembly 1 and the drive mechanism respectively. The locking mechanism includes a guide 205 and a locking member 204. The guide 205 is connected to the fixed assembly 1 and is arranged in the left-right direction. The locking member 204 has a locking groove 2041 in the front-back direction. The guide 205 is inserted into the locking groove 2041. The locking member 204 is also rotatably connected to the push rod 203. When the support platform 201 is flipped down to the lowest point, the guide 205 is engaged with the outer edge of the locking groove 2041.

[0073] When the slider 206 slides in the front-to-back direction, the locking member 204 slides synchronously with the slider 206, and the guide member 205 is inserted into the locking groove 2041, thus providing guidance as the locking member 204 slides. When the slider 206 flips downward, the locking member 204 flips synchronously around the guide member 205, and after the slider 206 rotates until the limiting rod 103 engages with the slide groove 1011, the edge of the locking groove 2041 abuts against the guide member 205, thereby limiting the position of the slider 206. In this embodiment, the abutment between the guide member 205 and the edge of the locking groove 2041, and the engagement between the limiting rod 103 and the edge of the slide groove 1011, together provide a hanging force for the power battery and the support platform 201, improving the stability of the support platform 201 and the power battery at this time.

[0074] In some embodiments, please refer to Figures 1 to 3 The hoisting assembly 3 includes a hoisting driver 302 and a hoisting mechanism. The hoisting driver 302 is rotatably connected to the fixed assembly 1 and is a telescopic component. The hoisting mechanism is rotatably connected to the fixed assembly 1 and is also rotatably connected to the drive end of the hoisting driver 302. The hoisting mechanism is used to hoist the power battery.

[0075] After the lifting mechanism is connected to the vehicle-mounted power battery, the vehicle-mounted power battery is separated from the fixed assembly 1 by the extension and rotation of the lifting driver 302. Then, the new power battery is connected to the lifting mechanism, and the new power battery is installed onto the fixed assembly 1 by the retraction and reset of the lifting driver 302. This embodiment eliminates the need for manual handling of the power battery; the unloading of the original vehicle-mounted power battery and the installation of the new power battery are achieved through the lifting driver 302 and the lifting mechanism, reducing labor intensity.

[0076] Optionally, the lifting drive 302 can be a hydraulic expansion joint or a pneumatic expansion joint.

[0077] In some embodiments, please refer to Figure 1 As shown in the figure, the hoisting mechanism includes a hoisting arm 301 rotatably connected to the fixed component 1. A reinforcing rod 303 is connected to the middle part of the hoisting arm 301. The reinforcing rod 303 is rotatably connected to the hoisting driver 302. One end of the hoisting arm 301 is rotatably connected to the fixed component 1, and the other end is used to connect to the power battery.

[0078] One end of the lifting boom 301 is connected to the fixed component 1, and the other end is connected to the power battery. The lifting driver 302 is connected to the lifting boom 301 through the reinforcing rod 303. During the lifting process, the lifting driver 302 extends, retracts, and rotates to control the lifting boom 301, enabling the lifting boom 301 to unload or install the power battery.

[0079] Optionally, multiple lifting arms 301 are provided, and the reinforcing rods 303 of each lifting arm 301 are connected to each other. The multiple lifting arms 301 are controlled by the lifting driver 302.

[0080] Based on the same inventive concept, the present invention also provides a new energy engineering vehicle. The new energy engineering vehicle includes the on-board battery swapping device described in any of the above embodiments.

[0081] The new energy engineering vehicle provided by this invention adopts the aforementioned new energy engineering vehicle, in which the robotic arm mounting frame 401, the operator's cab mounting frame 402, and the power equipment mounting frame 403 are connected to form an integral frame assembly 4, which is installed on the vehicle body. The frame assembly 4 provides support and installation positions for the fixed assembly 1, the support assembly 2, and the hoisting assembly 3. Simultaneously, the robotic arm, operator's cab, power equipment, etc., can all be connected to the vehicle body through the frame assembly 4. The frame assembly 4 not only provides installation positions for the aforementioned components but also achieves overall planning of the installation area, making the overall vehicle layout more reasonable and compact. When the power battery needs to be replaced, the support assembly 2 is slid to the rear of the fixed assembly 1. After the support assembly 2 slides to its farthest end, it flips downward under gravity, causing the power battery connected to the support assembly 2 to flip downward simultaneously. After the support assembly 2 flips downward to the designated position, the hoisting assembly 3 removes the on-board power battery. Then, the hoisting assembly 3 hoists the new power battery to the connection with the support assembly 2, after which the support assembly 2 rotates upward and slides back to its original position in the front-rear direction. This invention eliminates the need for external hoisting equipment for battery replacement, enabling more convenient and faster battery swapping at field sites and ensuring the continuous range of new energy engineering vehicles. Furthermore, it eliminates the need for dedicated battery swapping stations, reducing costs and facilitating the widespread adoption of new energy engineering vehicles.

[0082] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
