[0002] With the development of the electric vehicle industry, the battery capacity of electric vehicles has become a bottleneck in its development. In order to continuously provide continuous power for electric vehicles and overcome the disadvantage of long charging time, the method of battery replacement is used to provide continuous power for electric vehicles.

[0003] New energy commercial vehicles, such as logistics vehicles and light trucks, often use a mid-mounted battery (the battery is located in the middle of the chassis). Battery swapping is achieved by using a battery swapping device at the rear end to push and pull the battery, meaning the battery is pulled outward when removed and pushed in when inserted.

[0004] Existing patents such as CN 114701391 A and CN 115158246 A disclose push-pull battery swap stations suitable for new energy commercial vehicles. These systems present at least the following technical challenges: 1. Ground rails are required for the battery swap unit to travel, but the route for the unit is often located uphill from the passage, making track installation difficult. 2. Even if ground rails were feasible, they would affect the driving experience. Over time, debris would accumulate on both sides of the rails, affecting their aesthetics. Frequent cleaning would otherwise affect the movement of the battery swap unit and damage the rails after repeated vehicle travel. Summary of the Invention

The battery swap station of the present invention does not need to set a track for the battery swap device in the battery swap channel 2 by suspending the battery swap device, which facilitates the passage of vehicles and also facilitates the layout and installation of various devices.

[0031] See attached Figure 1 and 2 In order to facilitate the positioning of the new energy commercial vehicle 1 to be replaced with a battery in the battery replacement channel 2, a front wheel centering device 6 and a rear wheel centering device 7 are provided in the battery replacement channel 2 for positioning the front wheels and rear wheels of the new energy commercial vehicle 1 respectively.

[0032] See attached Figure 2 The battery storage rack 3 is arranged in the battery compartment 4, and a charger for charging the batteries is provided in the battery compartment 4.

[0033] See attached Figure 1-4The above-mentioned work station conversion device includes two hanging rails 8 arranged in parallel, a hanging rail mounting frame 9 arranged between the hanging rails 8 and the ground, a translation bracket 10 limited on both sides of the two hanging rails 8, and a translation drive assembly that drives the translation bracket 10 to move along the hanging rails 8. The power exchange device is connected to the translation bracket 10. The translation drive assembly includes a rack 12 fixed on the hanging rail 8, a gear 11 meshed with the rack 12, and a translation drive motor 13 fixed on the translation bracket 10 and connected to the gear 11. In addition, the translation drive assembly can also be a chain mechanism driven by a motor, and the translation bracket 10 is connected to the chain. A guide assembly for guiding the translation bracket 10 is provided between the hanging rail 8 and the translation bracket 10, and the guide assembly includes a translation slide rail 14 fixed on the hanging rail 8 and a translation slider 15 fixed on the translation bracket 10.

[0034] See attached Figure 4 , since there are multiple battery compartments in the battery storage rack 3 in the horizontal direction and multiple battery compartments in the height direction. Therefore, the translation bracket 10 is provided with at least one set of lifting drive components 18 for driving the battery exchange device to rise and fall, so that the battery exchange device can be moved to the entrance and exit of the corresponding battery compartment and aligned with the entrance and exit of the battery compartment of the new energy commercial vehicle 1 to take and place the battery. The above-mentioned lifting drive component 18 can be a gear rack structure driven by a motor, an electric cylinder, a rigid chain, or other devices that can achieve linear drive. In this embodiment, the lifting drive component 18 adopts a rigid chain.

[0035] See attached Figure 4 The above-mentioned battery exchange device includes a battery exchange bracket 16 with a battery temporary storage position and a battery push-pull device 17 arranged on the battery exchange bracket 16 and equipped for each battery temporary storage position.

[0036] A connecting assembly is provided between the execution end of each lifting drive assembly 18 and the battery-exchanging bracket 16. The connecting assembly includes a first connecting seat 19 provided on the battery-exchanging bracket 16, a second connecting seat 20 provided at the execution end of the lifting drive assembly 18, a first articulated seat 21 hinged to the first connecting seat 19, and a second articulated seat 22 hinged at both ends to the first articulated seat 21 and the second connecting seat 20.

[0037] In this embodiment, two groups of lifting drive components 18 are provided on each side of the battery exchange bracket 16. By driving one or more groups of lifting drive components 18 and cooperating with the connecting components, the battery exchange device can be adjusted within a certain angle range and lifted and lowered in height, so that the temporary storage position of the battery thereon is flush with the battery compartment in the battery storage rack 3 or the bottom of the battery compartment of the new energy commercial vehicle 1, which facilitates the push-pull battery exchange. A connecting plate is also provided between the boxes of adjacent lifting drive components 18 to ensure stability. The connecting components of the two embodiments are each provided with a group on the same side of the battery exchange bracket 16, which can reduce the relative position movement between the battery exchange bracket 16 and the lifting drive component, so that the process of the battery entering and exiting the battery exchange bracket 16 is stable.

[0038] Example 1: See attached Figure 1-4 In this embodiment, a battery storage rack 3 is provided on one side of the battery swap channel 2 and is equipped with a station conversion device and a battery swap device. The battery swap device is provided with at least two temporary battery storage locations, one for temporarily storing depleted batteries from the new energy commercial vehicle 1 and one for storing fully charged batteries from the battery storage rack 3. In this embodiment, two temporary battery storage locations are provided on the battery swap bracket 16.

[0039] In the initial state, the battery swap device is located on the battery entrance and exit side of the battery storage rack 3 to facilitate the new energy commercial vehicle 1 to enter the battery swap channel and stop at the battery swap position. One battery temporary storage position of the battery swap device stores a fully charged battery, while the other is empty. When the commercial vehicle drives to the designated area in the channel, the front wheel centering device 6 and the rear wheel centering device 7 will push and tighten the front and rear wheels of the vehicle to automatically fix the commercial vehicle in the battery swap position required by the battery swap device for subsequent battery swapping.

[0040] While the front wheel centering device 6 and the rear wheel centering device 7 push and fix the commercial vehicle, the work station conversion device drives the battery exchange device to move to the rear of the new energy commercial vehicle 1, and automatically scans the rear of the commercial vehicle after the commercial vehicle is fixed, automatically calculates and adjusts the upper and lower heights and left and right angles of the battery exchange device so that the temporary battery storage position without a battery is flush with the bottom of the battery compartment of the quasi-commercial vehicle, and the matching battery push-pull device 17 pulls the commercial vehicle battery into the current battery temporary storage position; then, by adjusting the height of the battery exchange device upward or downward so that the fully charged battery is aligned with the battery compartment of the commercial vehicle, the matching battery push-pull device 17 pushes the fully charged battery into the battery compartment of the commercial vehicle, thereby completing the battery exchange.

[0041] After the battery swap is completed, the front wheel centering device 6 and the rear wheel centering device 7 that receive the signal release the limit on the vehicle, and the vehicle can drive out of the channel. The workstation conversion device and the lifting drive assembly 18 drive the battery temporary storage position with the low-charged battery in the battery swap device to move to the side of the battery compartment without batteries in the battery storage rack 3, and by adjusting the height of the battery swap device, the matching battery push-pull device 17 pushes the low-charged battery into the battery compartment to charge it. At this time, all the battery temporary storage positions in the battery swap device have no batteries; then, the workstation conversion device and the lifting drive assembly 18 drive any battery temporary storage position in the battery swap device to move to the entrance and exit side of the battery compartment with fully charged batteries in the battery storage rack 3, and the matching battery push-pull device 17 pulls the fully charged battery into the battery temporary storage position to prepare for the next battery swap.

[0042] Example 2: See attached Figure 5 In this embodiment, a battery storage rack 3 is provided on each side of the battery exchange channel 2, each equipped with a station conversion device and a battery exchange device. Both battery exchange devices are equipped with a temporary battery storage position for storing low-charged batteries or fully charged batteries. Unlike the first embodiment, in this embodiment, the two battery exchange devices respectively pull out low-charged batteries and push in fully charged batteries for the new energy commercial vehicle 1.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and not to limit it; although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents; without departing from the spirit of the technical solution of the utility model, they should all be included in the scope of the technical solution for protection of the utility model.
