Description

Technical Field

[0001] The present invention belongs to the technical field of new energy battery replacement, and more specifically, relates to a vehicle-mounted battery replacement device and a new energy engineering vehicle. Background Art

[0002] Electrified engineering equipment is gradually replacing old-fashioned internal combustion engine engineering equipment. However, engineering machinery and equipment such as loaders and excavators consume extremely high energy due to long-term heavy operations. If the power battery is not sustained or replaced, it will seriously affect the normal operation of new energy engineering vehicles. Since it takes a long time to charge and sustain the power battery, which affects the working cycle, battery replacement has become an important means to effectively solve the range anxiety problem of electrified engineering equipment.

[0003] However, currently, the battery replacement work of engineering vehicles such as loaders and excavators usually needs to be carried out in a battery replacement station. Not only does it require the construction of a battery replacement station, but also special battery replacement equipment needs to be configured, which accounts for a quite large proportion in the investment cost and operation cost of new energy loaders, excavators and other engineering vehicles.

[0004] Although this battery replacement mode is more suitable for the scenario of a new energy engineering vehicle cluster, for the scenario where there are not many new energy engineering vehicles and continuous operation is required, the route investment cost of building a battery replacement station will be very high, and each battery replacement needs to be carried out in the battery replacement station, which will complicate the battery replacement operation of new energy loading engineering vehicles and increase the time cost and labor cost.

[0005] In order to reduce the battery replacement cost of new energy engineering vehicles, some users with fewer new energy engineering vehicles use lifting equipment to replace the power battery. However, most construction machinery vehicles need to work outdoors, and the working environment is limited. Large construction machinery such as lifting equipment simply cannot be used, which not only seriously affects the normal use of new energy engineering vehicles, but also poses a great obstacle to the popularization of new energy engineering vehicles. In addition, since new energy engineering vehicles need to carry power batteries, the components on the vehicle body increase. How to reasonably layout the position of the power battery to facilitate the replacement of the power battery, and make the hydraulic equipment and power equipment on the engineering vehicle more reasonably distributed is an urgent problem to be solved. Summary of the Invention

[0006] The purpose of the present invention is to provide a vehicle-mounted battery replacement device and a new energy engineering vehicle, aiming to solve the problems in the prior art that the replacement of the power battery of new energy engineering vehicles is limited, the cost is relatively high, which seriously affects the popularization and use of new energy engineering vehicles, and that there are many components to be installed on new energy engineering vehicles and the layout is not compact and reasonable enough.

Among them, the first relief hole corresponds to the slewing bearing mounting position, the second relief hole corresponds to the driving motor mounting position, and the third relief hole corresponds to the regulating valve mounting position.

[0016] In combination with the first aspect, in a possible implementation manner, the fixing assembly includes a plurality of fixing members spaced apart in the left-right direction, and the plurality of fixing members are respectively connected to the frame, and the support assembly is slidably connected to the plurality of fixing members in the front-rear direction.

[0017] In combination with the first aspect, in a possible implementation manner, the fixing assembly is provided with a chute in the front-rear direction, and a limiting rod is arranged in the chute. The axis of the limiting rod is parallel to the left-right direction. The support assembly includes:

[0018] The support mechanism includes a support platform slidably connected to the vehicle frame in the front-rear direction and a sliding member connected to the rear side of the support platform. The sliding member is slidably disposed in the chute, and a limiting groove is formed in the sliding member in the front-rear direction. The limiting rod is inserted into the limiting groove. When the sliding member slides backward to the most distal end, the sliding member rotates downward around the limiting rod; and

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

[0023] In combination with the first aspect, in a possible implementation manner, the support component further includes a locking mechanism respectively connected to the fixed component and the driving mechanism. The locking mechanism includes:

When the power battery needs to be replaced, the support assembly is slid to the rear side of the fixed assembly. After the support assembly slides to the farthest end, the support assembly flips downward under the action of gravity, so that the power battery connected to the support assembly flips downward synchronously.

[0046] Please refer to Figures 1 to 6 , and now the on-vehicle battery swapping device and the new energy engineering vehicle provided by the present invention will be described. The on-vehicle battery swapping device includes a frame assembly 4, a fixing assembly 1, a supporting assembly 2 and a hoisting assembly 3. The frame assembly 4 is connected to the vehicle body. The frame assembly 4 includes a robotic arm mounting bracket 401, and an operator's cab mounting bracket 402 and a power equipment mounting bracket 403 respectively arranged on both sides of the robotic arm mounting bracket 401 in the left and right directions; the fixing assembly 1 is arranged at the rear side of the robotic arm mounting bracket 401; the supporting assembly 2 is arranged at the rear side of the fixing assembly 1 and is slidably connected to the fixing assembly 1 in the front and back directions. The supporting assembly 2 is also rotatably connected to the fixing assembly 1 around a first axis, and the first axis is arranged at an angle with the front and back directions. The power battery is installed on the supporting assembly 2. When the supporting assembly 2 slides backward to the farthest end, the supporting assembly 2 turns downward around the first axis; the hoisting assembly 3 is rotatably connected to the fixing assembly 1, and the hoisting assembly 3 is used for hoisting the power battery.

[0047] Compared with the prior art, the vehicle-mounted battery replacement device provided by the present invention has a mechanical arm mounting frame 401, an operating room mounting frame 402 and a power equipment mounting frame 403 connected to form an integral frame assembly 4, and is installed on the vehicle body. The frame assembly 4 provides support force and installation position for the fixed assembly 1, the support assembly 2, and the hoisting assembly 3. At the same time, the mechanical arm, the operating room, the power equipment, etc. can be connected to the vehicle body through the frame assembly 4. The frame assembly 4 not only provides the installation position for the above, but also realizes the overall planning of the installation area, making the layout of the whole vehicle more reasonable and compact. When the power battery needs to be replaced, the support assembly 2 is slid to the rear side of the fixed assembly 1. After the support assembly 2 slides to the farthest end, the support assembly 2 flips downward under the action of gravity, so that the power battery connected to the support assembly 2 is synchronously flipped downward. After the support assembly 2 flips down to the specified position, the hoisting assembly 3 removes the vehicle-mounted power battery. Then, the hoisting assembly 3 hoists the new power battery to connect with the support assembly 2, and then the support assembly 2 rotates upward and slides to reset in the front and rear directions. The present invention does not require the use of external lifting equipment to replace the power battery, and can more conveniently and quickly replace the power battery at work sites such as in the field, ensuring the continuous endurance of new energy engineering vehicles. At the same time, there is no need to build a dedicated battery replacement station, which reduces the cost of battery replacement and is conducive to the large-scale promotion of new energy engineering vehicles.

[0048] It should be noted that when the operating room mounting frame 402 is arranged on the left side of the robot arm mounting frame 401, the power equipment mounting frame 403 is arranged on the right side of the robot arm mounting frame 401. When the operating room mounting frame 402 is arranged on the right side of the robot arm mounting frame 401, the power equipment mounting frame 403 is arranged on the left side of the robot arm mounting frame 401. The above arrangement positions are all possible and are not limited here.

[0049] In some embodiments, see Figure 1 The robot arm mounting frame 401 includes a robot arm mounting position, a slewing support mounting position, a drive motor mounting position and a control valve mounting position distributed from front to back, and the fixing component 1 is arranged 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 driving motor mounting position, and the hydraulic main valve is installed at the regulating valve mounting position. The above-mentioned equipment is distributed in sequence along the front and rear directions to avoid mutual interference, so that the layout on the robotic arm mounting frame 401 is reasonable and neat.

[0051] It should be noted that the upper part of an engineering vehicle such as an excavator or a loader can rotate, and the rotary motor is used to drive the upper part of the vehicle to rotate.

[0052] In some embodiments, see Figure 1, the robotic arm mounting bracket 401 includes a support base 4011 and two mounting plates 4012 respectively located on the left and right sides of the support base 4011. Corresponding robotic arm mounting holes 4016 are respectively formed in the two mounting plates 4012, and the robotic arm mounting holes 4016 form a robotic arm mounting position.

[0053] The robotic arm mounting position is provided on the mounting plate 4012. The robotic arm is inserted into the robotic arm mounting hole 4016 to achieve rotational connection with the mounting plate 4012 and perform operations under the action of the hydraulic drive. During the operation of the robotic arm, multi-directional rotation is required. Connecting with the mounting plate 4012 can avoid interference with the support base 4011 during the operation and ensure the flexible operation of the robotic arm.

[0054] In some embodiments, please refer to Figure 1 , the slewing bearing mounting position, the drive motor mounting position and the regulating valve mounting position are all provided on the support base 4011. The support base 4011 is provided with a first relief hole 4013, a second relief hole 4014 and a third relief hole 4015. Among them, the first relief hole 4013 corresponds to the slewing bearing mounting position, the second relief hole 4014 corresponds to the drive motor mounting position, and the third relief hole 4015 corresponds to the regulating valve mounting position.

[0055] The design of the first relief hole 4013, the second relief hole 4014 and the third relief hole 4015 can, on the one hand, reduce the weight of the support base 4011 to achieve the lightweight of the whole vehicle, and on the other hand, save materials and reduce costs. In addition, the connecting piece 102 can also pass through the first relief hole 4013 to connect the support base 4011 with the vehicle body, realizing the fixation of the frame assembly 4 and the vehicle body.

[0056] As a specific implementation manner of the cab mounting bracket 402, please refer to Figure 1 , the cab mounting bracket 402 includes a cab mounting position 4021 and a heat dissipation system mounting position 4022 distributed from front to back. The cab is located at the front of the cab mounting bracket 402, which is beneficial for the driver to observe the external situation and broaden the field of vision. The heat dissipation system mounting position 4022 is used to install a radiator, and the radiator dissipates heat from the motor and the cab air conditioner.

[0057] As a specific implementation manner of the power equipment mounting bracket 403, please refer to Figure 1 , the power equipment mounting bracket 403 includes a power assembly mounting position 4031 and a fuel tank mounting position 4032 distributed from front to back. Power equipment such as motors is arranged at the power assembly mounting position 4031, and the motor drives the main pump to deliver hydraulic oil to the main valve. The hydraulic fuel tank and the hydraulic system heat dissipation device are both arranged at the fuel tank mounting position 4032.

[0058] In some embodiments, please refer to Figures 1 to 4, the 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 bracket 401, and the supporting component 2 is slidably connected to the plurality of fixing members 101 in the front - rear direction.

[0059] In this embodiment, the supporting component 2 is slidably connected to the plurality of fixing members 101, thereby increasing the contact area between the supporting component 2 and the fixing component 1, and improving the stability and firmness of the connection. Since the power battery is relatively heavy, during the sliding and flipping of the supporting component 2 with the power battery loaded, the connection may easily fail. To avoid damage to the fixing members 101 or the supporting component 2, a plurality of fixing members 101 are provided to be connected to the supporting component 2 to ensure that the fixing members 101 and the supporting component 2 are not damaged during the replacement process.

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

[0061] The connecting member 102 connects the plurality of fixing members 101 to form an integral structure. Compared with the solution where the plurality of fixing members 101 are independently arranged and have no connection relationship with each other, the connection firmness between the plurality of fixing members 101 and the robotic arm mounting bracket 401 is further increased, and at the same time, the problem of connection failure between the fixing members 101 and the supporting component 2 after the fixing members 101 are stressed can be avoided.

[0062] In some embodiments, please refer to Figure 3 , the fixing component 1 is provided with a sliding groove 1011 in the front - rear direction. A limiting rod 103 is arranged in the sliding groove 1011, and the axis of the limiting rod 103 is parallel to the left - right direction. The supporting component 2 includes a supporting mechanism and a driving mechanism. The supporting mechanism includes a supporting platform 201 slidably connected to the robotic arm mounting bracket 401 in the front - rear direction and a sliding member 206 connected to the rear side of the supporting platform 201. The sliding member 206 is slidably arranged in the sliding groove 1011, and the sliding member 206 is provided with a limiting groove 2061 in the front - rear direction. The limiting rod 103 is inserted into the limiting groove 2061. When the sliding member 206 slides to the farthest end on the side away from the fixing component 1, the sliding member 206 rotates downward around the limiting rod 103; the driving mechanism is rotatably connected to the fixing component 1, and the driving end of the driving mechanism is rotatably connected to the supporting platform 201 for driving the supporting platform 201 to slide in the front - rear direction.

[0063] When the engineering vehicle is in normal use, the sliding member 206 slides to approach or coincide with the fixed assembly 1 in the front-rear direction. When the power battery needs to be replaced, the sliding member 206 slides along the chute 1011 to the side away from the fixed assembly 1. After the sliding member 206 slides to the designated position, the sliding member 206 flips downward until the limiting rod 103 is hooked to the edge of the limiting groove 2061. In this embodiment, the hooking of the limiting rod 103 to the edge of the limiting groove 2061 prevents the sliding member 206 from separating from the fixed assembly 1, so that the power battery can be further removed by the hoisting assembly 3. The structural components of this embodiment realize the limitation of the support platform 201 through the limiting rod 103 arranged in the chute 1011 and the limiting groove 2061 opened on the sliding member 206, without additionally arranging a limiting structure, avoiding the complex limiting structure from occupying too much space on the robotic arm mounting bracket 401 and not affecting the normal use of the engineering vehicle, which is beneficial to the lightweight of the whole vehicle.

[0064] Specifically, the limiting rod 103 is arranged on the side of the fixed assembly 1 close to the support platform 201.

[0065] In some embodiments, please refer to Figure 6 , on the side of the sliding member 206 close to the fixed assembly 1, there is an arc-shaped relief portion 2062, and the relief portion 2062 is located at the top of the sliding member 206.

[0066] When the sliding member 206 flips downward, the side of the limiting rod 103 away from the support platform 201 will rotate upward. The arrangement of the arc-shaped relief portion 2062 can prevent interference with other components during flipping, and can also save materials and reduce costs.

[0067] Optionally, the chute 1011 can be opened on the side wall of the fixed assembly 1 and communicate with the outside in the left-right direction. In this case, even if the relief portion 2062 is not provided, the sliding member 206 will not interfere with the fixed assembly 1 during flipping, but it may affect other components on the robotic arm mounting bracket 401. The chute 1011 can also be opened in the middle part of the fixed assembly 1 in the left-right direction, that is, the left and right sides of the chute 1011 are closed. In this case, without setting the relief portion 2062, there will be no interference with the fixed assembly 1 during flipping. In addition, the chute 1011 can also be opened on the fixed assembly 1 in the front-rear direction, and the top and / or bottom of the chute 1011 are closed. In this case, if the relief portion 2062 is not provided, the sliding member 206 may interfere with the top of the fixed assembly 1 during flipping.

[0068] Optionally, please refer to Figure 4 , the fixed assembly 1 is provided with a through chute 1011 in the front-rear direction, the top and bottom of the chute 1011 are closed, and on the side close to the support assembly 2, a relief groove is opened at the bottom of the fixed assembly 1, and the relief groove communicates with the chute 1011 to prevent interference between the sliding member 206 and the bottom of the chute 1011 during flipping.

[0069] In some embodiments, referring 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 assembly 1; the push rod 203 is connected to the support platform 201. The push rod 203 extends in the left - right direction, and the telescopic end of the telescopic driver 202 is rotatably connected to the push rod 203.

[0070] The fixed end of the telescopic driver 202 is rotatably connected to the fixed assembly 1. When it is necessary to control the support platform 201 to slide in the front - rear direction, the telescopic driver 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 driving mechanism rotates around the push rod 203 and the fixed assembly 1 respectively, avoiding interfering with the flipping of the support platform 201. In this embodiment, there is no need to manually push the support platform 201 to slide. The sliding of the support platform 201 is realized by the telescopic driver 202, which saves more labor. Moreover, compared with the driving method of the lead screw, the solution in this embodiment avoids occupying too much space after the slider 206 is reset.

[0071] Optionally, the telescopic driver 202 is a hydraulic telescopic member or a pneumatic telescopic member.

[0072] In some embodiments, referring to Figures 1 to 3 , the support assembly 2 further includes a locking mechanism respectively connected to the fixed assembly 1 and the driving mechanism. The locking mechanism includes a guide member 205 and a locking member 204. The guide member 205 is connected to the fixed assembly 1 and is arranged in the left - right direction; the locking member 204 is provided with a locking groove 2041 in the front - rear direction. The guide member 205 is inserted into the locking groove 2041, and the locking member 204 is also rotatably connected to the push rod 203. When the support platform 201 flips downward to the lowest point, the guide member 205 is hooked to the outer edge of the locking groove 2041.

[0073] When the slider 206 slides in the front - rear direction, the locking member 204 slides synchronously with the slider 206, and the guide member 205 is inserted into the locking groove 2041, thereby providing a guiding function along with the sliding of the locking member 204. 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 is hooked to the sliding 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 of the edge of the guide member 205 against the locking groove 2041 and the hooking of the limiting rod 103 to the edge of the sliding groove 1011 jointly 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, referring toFigures 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 fixing assembly 1, and the hoisting driver 302 is a telescopic member; the hoisting mechanism is rotatably connected to the fixing assembly 1, and the hoisting mechanism is also rotatably connected to the driving end of the hoisting driver 302. The hoisting mechanism is used to hoist the power battery.

[0075] After the hoisting mechanism is connected to the vehicle-mounted power battery, the vehicle-mounted power battery is separated from the fixing assembly 1 by the extension and rotation of the hoisting driver 302. Then, a new power battery is connected to the hoisting mechanism, and the new power battery is installed on the fixing assembly 1 by the retraction and reset of the hoisting driver 302. In this embodiment, there is no need to manually carry the power battery, and the unloading of the original vehicle-mounted power battery and the installation of the new power battery are realized through the hoisting driver 302 and the hoisting mechanism, reducing the labor intensity.

[0076] Optionally, the hoisting driver 302 is a hydraulic telescopic device or a pneumatic telescopic device.

[0077] In some embodiments, please refer to Figure 1 and the figure. The hoisting mechanism includes a hoisting arm 301 rotatably connected to the fixing assembly 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 fixing assembly 1, and the other end is used to connect to the power battery.

[0078] One end of the hoisting arm 301 is connected to the fixing assembly 1, and the other end is connected to the power battery. The hoisting driver 302 is connected to the hoisting arm 301 through the reinforcing rod 303. During the hoisting process, the hoisting driver 302 expands and contracts and rotates to control the hoisting arm 301, so that the hoisting arm 301 completes the unloading or installation of the power battery.

[0079] Optionally, there are multiple hoisting arms 301, and the reinforcing rods 303 of each hoisting arm 301 are connected to each other, and the multiple hoisting arms 301 are controlled by the hoisting 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 vehicle-mounted battery swapping device according to any one of the above.

[0081] The new energy engineering vehicle provided by the present invention adopts the above-mentioned new energy engineering vehicle. The robotic arm mounting bracket 401, the operator cab mounting bracket 402 and the power equipment mounting bracket 403 are connected to form an integral vehicle frame assembly 4, which is installed on the vehicle body. The vehicle frame assembly 4 provides a supporting force and a mounting position for the fixing assembly 1, the supporting assembly 2 and the hoisting assembly 3. At the same time, the robotic arm, the operator cab, the power equipment, etc. can all be connected to the vehicle body through the vehicle frame assembly 4. The vehicle frame assembly 4 not only provides the mounting position for the above-mentioned components, but also realizes the overall planning of the mounting area, making the layout of the whole vehicle more reasonable and compact. When the power battery needs to be replaced, the supporting assembly 2 is slid to the rear side of the fixing assembly 1. After the supporting assembly 2 slides to the farthest end, the supporting assembly 2 turns downward under the action of gravity, so that the power battery connected to the supporting assembly 2 turns downward synchronously. After the supporting assembly 2 turns downward to the specified position, the hoisting assembly 3 unloads the in-vehicle power battery. Then, the hoisting assembly 3 hoists a new power battery to be connected to the supporting assembly 2, and then the supporting assembly 2 rotates upward and slides back and forth to reset. The present invention does not need to use an external hoisting device to replace the power battery, and can more conveniently and quickly replace the power battery at a work site such as the wild, ensuring the continuous cruising ability of the new energy engineering vehicle. At the same time, there is no need to establish a dedicated power exchange station, reducing the power exchange cost and being beneficial to the large-scale promotion of the new energy engineering vehicle.

[0082] The foregoing are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
