Description

Technical Field

[0001] The utility model belongs to the technical field of battery replacement, and specifically relates to a chassis-type battery replacement device for a heavy-duty truck. Background Art

[0002] With the increase in the number of electric vehicles, the problems caused by charging have gradually become prominent, such as slow charging and difficulty in finding charging stations. Therefore, the battery replacement mode that can efficiently replenish energy and solve the problem of charging difficulties has gradually been popularized and promoted. In the field of heavy-duty trucks, battery replacement heavy-duty trucks are also gradually being marketed. The current mainstream battery replacement methods are back-mounted battery replacement heavy-duty trucks and chassis-mounted battery replacement heavy-duty trucks. Back-mounted battery replacement heavy-duty trucks have a certain impact on cargo space, vehicle power and handling performance. The existing back-mounted scheme has the following shortcomings: First, from the perspective of vehicle design, the weight of the battery box of the existing scheme is all concentrated on the front axle of the vehicle, increasing the load on the front axle; second, from the perspective of freight, the battery box of the existing scheme occupies the cargo box space, affecting the vehicle's transportation capacity; third, from the perspective of energy consumption, because the battery box of the existing scheme is arranged behind the cab, it affects the forward design of the cab's low drag coefficient, and invisibly increases the energy consumption of the vehicle. At present, mainstream heavy-duty truck manufacturers are studying wheel-side drive products, and plan to design the cancellation of the drive shaft between the main beams to provide enough space for the chassis to load the battery. Chassis-type battery-swap heavy trucks do not take up cargo box space. At the same time, the supporting battery-swap stations occupy a small area and the battery-swap equipment is small in size. Therefore, it is very necessary to design a chassis-type heavy truck battery-swap device to improve the efficiency and safety of battery-swap, and to improve the chassis-type battery-swap system.

The guide pins 109 play a role in guiding and positioning, facilitating the docking between the battery swapping vehicle 1 and the chassis of the heavy truck to avoid misalignment. The cushion blocks 110 are used to place the battery.

[0030] The following further describes the chassis - type heavy - truck vehicle battery swapping device of the present utility model in conjunction with embodiments:

[0031] After the heavy - truck vehicle chassis drives into the battery swapping station, the grating and rangefinder in the station give the accurate coordinates of the battery 6 with insufficient power on the chassis. The battery swapping vehicle 1 located at the 3122nd position of the second buffer starts. The lidar 104 scans the road conditions in real - time and plans the optimal path for the battery swapping vehicle 1 to move under the vehicle chassis. After the battery swapping vehicle 1 reaches the corresponding position under the vehicle chassis, the control lifting platform 107 drives the floating platform 108 to rise. If the vehicle chassis has a certain inclination angle relative to the ground, during the process of the floating platform 108 gradually rising and contacting the vehicle chassis, under the action of the chassis, the spring 105 is compressed according to the actual inclination angle, and the floating platform 108 adapts to the inclination and fits perfectly with the vehicle chassis. At this time, the guide pin 109 is completely inserted into the pin hole above the battery 6 with insufficient power. The deceleration motor 106 is started, and the bolts fixing the battery 6 with insufficient power become loose, and the battery 6 with insufficient power falls on the cushion block 110 above the floating platform 108. Then the control lifting platform 107 descends to the original position;

[0032] Then the battery swapping vehicle 1 carries the battery 6 with insufficient power and drives back to the second buffer 3122. The control lifting platform 107 drives the battery 6 with insufficient power to rise until the battery 6 with insufficient power is engaged with the magnetic - absorption slider 314 above the buffer track 313. The magnetic - absorption slider 314 located in the second buffer 3122 drags the battery 6 with insufficient power along the buffer track 313 towards the third buffer 3123. The magnetic - absorption slider 314 located in the first buffer 3121 drags the fully - charged battery 5 to move to the second buffer 3122 and then stops moving. The fully - charged battery 5 disengages from the magnetic - absorption slider 314 and falls on the cushion block 110 above the floating platform 108 of the battery swapping vehicle 1.

[0033] After the battery swapping vehicle 1 loads the fully - charged battery 5, it drives into the corresponding position under the vehicle chassis. The control lifting platform 107 drives the fully - charged battery 5 to rise, and the deceleration motor 106 is started to fasten the fully - charged battery 5 on the vehicle chassis. The lifting platform 107 descends to the original position, and the battery swapping vehicle 1 drives back to the second buffer 3122 and parks, thus completing the battery swapping for the heavy - truck vehicle chassis.

[0034] Finally, the stacker 32 moves the battery 6 with insufficient power at the third buffer 3123 to the charging section 311 in an idle state for charging. The stacker 32 then moves the fully - charged battery 5 to the first buffer 3121. In this way, the third buffer 3123 is always in a state without a battery, and the first buffer 3121 always has fully - charged batteries 5 in reserve, effectively reducing the battery swapping time and improving the battery swapping efficiency. At the same time, the magnetic - absorption slider 314 moves back along the buffer track 313 to the first buffer 3121 and the second buffer 3122, facilitating the transportation of the battery during the next battery swapping.
