Description

Technical Field

[0001] This utility model relates to the field of battery charging and swapping technology, and more specifically, to a battery swapping station for new energy heavy trucks. Background Technology

[0002] As an important carrier of green transportation, new energy heavy-duty trucks are gradually transitioning from traditional diesel-powered to electric-powered power systems. These vehicles use large-capacity battery packs as their energy source, offering environmental advantages such as zero emissions and low noise. However, in actual operation, they face prominent problems such as long charging times and difficult battery maintenance. Currently, mainstream fast-charging solutions have many limitations: the charging process typically takes several hours, severely impacting transportation efficiency; high-power fast charging accelerates battery performance degradation, increasing the total life-cycle cost.

[0003] As supporting facilities for new energy vehicles, an increasing number of battery swapping stations are springing up. Also known as shared battery swapping stations or battery exchange stations, these stations allow heavy-duty trucks to directly replace their batteries with fully charged ones when the battery is depleted, continuing to power the truck.

[0004] However, existing battery swapping stations suffer from shortcomings such as unreasonable planning and layout, resulting in low swapping efficiency. For example, after removing the power battery from a heavy truck, it requires a charging bay. If there is no spare bay during battery swapping, the power battery must be placed in another location, which not only poses a risk of bumping and knocking but also affects the swapping efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a battery swapping station for new energy heavy-duty trucks to solve the problem of low battery swapping efficiency for heavy-duty trucks.

[0006] This utility model provides a battery swapping station for new energy heavy-duty trucks, comprising: a battery swapping station body, a parking eave, and a battery transport mechanism. The battery swapping station body includes a battery swapping chamber. The parking eave is suspended on the upper outer side of the battery swapping chamber, and a parking battery swapping area for heavy-duty trucks is configured below the parking eave. The battery swapping chamber has a battery swapping channel in the middle, one end of which passes through the battery swapping chamber and connects to the parking battery swapping area. Multiple battery swapping stations are symmetrically arranged in the battery swapping chamber relative to the battery swapping channel. Two buffer stations are also symmetrically arranged in the battery swapping chamber relative to the battery swapping channel. Both the battery swapping stations and the buffer stations are used to place power batteries. The battery transport mechanism is used to transport power batteries between the battery swapping chamber and the heavy-duty truck.

[0007] The battery swapping station for new energy heavy-duty trucks provided by this utility model has the following beneficial effects compared with the prior art:

[0008] The new energy heavy-duty truck battery swapping station of this utility model allows the heavy-duty truck to enter the parking battery swapping area under the parking eaves. The battery transport mechanism moves along the battery swapping channel to the vehicle chassis. The battery transport mechanism picks up the depleted battery and transfers it to a buffer station for temporary storage. Then, a fully charged battery is retrieved from the battery swapping station and installed into the vehicle. The symmetrically distributed battery swapping stations and buffer stations relative to the battery swapping channel create a closed-loop transport path, avoiding empty round trips by the equipment, reducing the travel distance of the battery transport mechanism, and improving battery swapping efficiency. Compared with existing technologies, traditional charging piles require vehicles to occupy charging positions for extended periods. This solution, through the separation of battery pre-charging and rapid replacement operations, allows vehicles to complete energy replenishment in just a few minutes. This utility model, through its multi-station symmetrical layout, ensures a stable and efficient power battery swapping process. This utility model optimizes the heavy-duty truck battery swapping process, shortening the vehicle's dwell time at the station. The multi-station collaborative mechanism improves battery turnover efficiency, and the symmetrical layout reduces equipment movement distance. The buffer station prevents chaotic battery stacking during the swapping process, ensuring an orderly connection between charging and replacement.

[0030] It should also be noted that the aforementioned X-axis, Y-axis and Z-axis are used only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0031] like Figure 1 and Figure 3 As shown in the figure, the new energy heavy-duty truck battery swapping station of this utility model includes: a battery swapping station body, a parking eaves 2, and a battery transport mechanism 3. The battery swapping station body includes a battery swapping room 1. The parking eaves 2 are suspended on the upper outer side of the battery swapping room 1, and the area below the parking eaves 2 is configured as a parking battery swapping area for heavy-duty trucks. The battery swapping room 1 has a battery swapping channel 11 in the middle. One end of the battery swapping channel 11 passes through the battery swapping room 1 and communicates with the parking battery swapping area. A plurality of battery swapping stations 12 are symmetrically arranged in the battery swapping room 1 relative to the battery swapping channel 11. Two buffer stations 13 are also symmetrically arranged in the battery swapping room 1 relative to the battery swapping channel 11. Both the battery swapping stations 12 and the buffer stations 13 are used to place power batteries. The battery transport mechanism 3 is used to transport power batteries between the battery swapping room 1 and the heavy-duty truck.

[0032] The battery swapping room 1 refers to the main structure that carries the battery swapping function. It can be constructed using a steel frame and protective panels, providing working space for storing and replacing power batteries. The parking eaves 2 refers to the cantilevered structure extending above the vehicle, which can be supported by a truss system. Heavy trucks can park in the battery swapping area below the parking eaves 2. The battery swapping channel 11 is a passageway that runs through the battery swapping room 1, through which power batteries can be moved in and out of the battery swapping room 1. The battery swapping station 12 is the storage area for power batteries, ensuring their stability during charging or standby. The buffer station is a battery transfer and storage area used to temporarily store power batteries awaiting replacement or those that have been removed. The battery handling mechanism 3 refers to a three-dimensional moving transport device, which can be a hoisting robotic arm working in conjunction with a track system to move power batteries between the battery swapping room 1 and the heavy truck.

[0033] Specifically, the heavy truck drives into the battery swapping area under the parking eaves 2, and the battery transport mechanism 3 moves along the battery swapping channel 11 to the vehicle chassis. A lifting device grabs the depleted battery and transfers it to the buffer station 13 for temporary storage. Then, a fully charged battery is retrieved from the battery swapping station 12 and installed into the vehicle. The symmetrically distributed battery swapping stations 12 and buffer stations 13 relative to the battery swapping channel 11 create a closed loop in the transport path, avoiding empty round trips for the equipment, reducing the travel distance of the battery transport mechanism 3, and improving battery swapping efficiency.

[0034] Compared to existing technologies, traditional charging stations require vehicles to occupy charging positions for extended periods. This solution, however, separates battery pre-charging and rapid battery swapping, allowing vehicles to recharge in just a few minutes. Furthermore, the multi-station symmetrical layout ensures a stable and efficient battery swapping process.

[0035] Through the above technical solutions, this application optimizes the battery replacement process for heavy-duty trucks, shortening vehicle dwell time at the station. The multi-station collaborative mechanism improves battery turnover efficiency, and the symmetrical layout reduces equipment movement distance. The buffer station prevents chaotic battery stacking during the swapping process, ensuring an orderly connection between charging and replacement.

[0036] Optionally, multiple support legs 4 are provided at intervals below the side of the parking eaves 2 away from the battery swapping room 1.

[0037] In this embodiment, in conjunction with the appendix Figure 1 As shown, the support leg 4 refers to the vertical load-bearing component set below the parking eaves 2 to support the cantilever structure. Specifically, it can be implemented using steel frame columns, which are distributed at intervals to form a multi-point support structure to distribute the load.

[0038] Specifically, the outriggers 4 are spaced apart and positioned below the edge of the parking eaves 2 on the side furthest from the battery swapping room 1, and are fixed to the steel structure beams of the parking eaves 2 by bolting or welding. When a heavy truck enters the parking and battery swapping area, the outriggers 4 bear the dynamic load generated by the vehicle's own weight and the battery transport, and their spaced distribution characteristics ensure that the load is evenly transferred to the ground foundation.

[0039] Optionally, the support leg 4 includes a body section 41 and an extension section 42. One end of the body section 41 is connected to the parking ledge 2, and the other end is detachably connected to the extension section 42.

[0040] In this embodiment, in conjunction with the appendix Figure 2 As shown, the main body section 41 refers to the main support part of the outrigger 4 that is directly connected to the parking eaves 2. It can be made of metal pipes or profiles welded together, and is used to transfer the load of the parking eaves 2 to the ground. The extension section 42 refers to the height-adjustable extension part of the outrigger 4. It can be connected to the main body section 41 and the extension section 42 using a flange structure, and is used to adapt to different ground height differences.

[0041] Specifically, the outrigger 4 forms a basic support structure through a fixed connection between the main body section 41 and the parking eaves 2, and the extension section 42 is installed at the end of the main body section 41 through a detachable connection. When the battery swapping station needs to adapt to different ground conditions, the extension section 42 can be replaced with modules of different lengths to meet the different foundation height requirements of the battery swapping station.

[0042] Optionally, a side guard plate 5 is provided between any two adjacent legs 4.

[0043] In this embodiment, in conjunction with the appendix Figure 1 As shown, the side protection plate 5 refers to the plate-like structure installed between adjacent support legs 4. It can be made of metal sheet or composite material plate and is used to protect heavy trucks, such as from rain.

[0044] Optionally, the battery swapping station enclosure further includes a top cover 6, which covers the battery swapping station enclosure and the parking eaves 2.

[0045] In this embodiment, in conjunction with the appendix Figure 4 As shown, the top cover 6 refers to the protective structure covering the battery swapping room 1 and the parking eaves 2. Specifically, it can be implemented by a combination of a metal frame and waterproof panels to prevent rainwater, dust and other external environmental factors from entering the battery swapping room 1 and the parking battery swapping area, and to prevent the equipment and batteries from getting damp or contaminated.

[0046] Optionally, the battery swapping station also includes a control room 7, which is located at one end of the battery swapping room 1. The top of the control room 7 has a maintenance platform that communicates with the battery swapping room 1, and a ladder that communicates with the maintenance platform is installed inside the control room 7.

[0047] In this embodiment, in conjunction with the appendix Figure 1 and attached Figure 3 As shown, control room 7 refers to an enclosed space independently located at one end of battery swapping room 1. It houses the entire station control system and staff office area, and can be constructed using a steel frame and panel enclosure. A ladder provides access from control room 7 to the maintenance platform, which centrally houses tools and personnel for equipment maintenance, facilitating regular maintenance of the equipment inside battery swapping room 1.

[0048] Optionally, the control room 7 has an observation window.

[0049] In this embodiment, the observation window refers to a transparent structure installed on the wall of the control room 7, which can be made of tempered glass or acrylic sheet, and is used to observe the operating status of the equipment in the battery swapping room 1 and the battery handling process in real time.

[0050] Optionally, a charging module is provided below the battery swapping station 12 for charging the power battery located on the battery swapping station 12.

[0051] In this embodiment, the charging module can be a cluster of devices that integrates functions such as power conversion, battery status interaction, heat dissipation control, and safety protection. Its main functions are: to convert the AC power from the power grid into the DC power required by the power battery, and to dynamically adjust the voltage and current according to the battery status; to charge multiple backup batteries at the same time, ensuring that the battery swapping station always has enough fully charged batteries in reserve; and to link with the battery management system and scheduling system of the battery swapping station to achieve matching between charging efficiency and battery swapping demand (for example, prioritizing charging the batteries that are about to be replaced).

[0052] Optionally, the battery swapping station enclosure further includes an equipment room 8, which is located below the battery swapping room 1, and the charging module is located inside the equipment room 8.

[0053] In this embodiment, in conjunction with the appendix Figure 1 As shown, equipment room 8 refers to the space that is independent of and located below battery swapping room 1. Specifically, it can be enclosed by a steel structure frame and fireproof partitions to centrally house charging modules and related electrical equipment, avoiding interference from the external environment.

[0054] Specifically, the equipment room 8 is located below the battery swapping room 1, forming a two-tiered layout. The charging module is integrated inside the equipment room 8, spatially separating the charging operation from the battery handling operation. After the power battery is transported to the battery swapping station 12, the charging module charges the battery through a preset power transmission path. It should be noted that the heat generated by the charger in the equipment room 8 can be exhausted by the charger's own exhaust fan through the louvers on the side of the equipment room 8. The heat generated by the battery can be exhausted by the exhaust fan and louvers on the top cover 6.

[0055] Optionally, the battery handling mechanism 3 includes a hoist, an X-axis moving frame, and a Y-axis moving frame. The X-axis moving frame is disposed above the battery swapping room 1 and the parking eaves 2, the Y-axis moving frame is disposed on the X-axis moving frame, and the hoist is disposed on the Y-axis moving frame.

[0056] The battery handling mechanism 3 further includes a first drive mechanism for driving the X-axis moving frame to move, a second drive mechanism for driving the Y-axis moving frame to move, and a third drive mechanism for driving the lifting device to lift.

[0057] In this embodiment, in conjunction with the appendix Figure 1 and attached Figure 3 As shown, the lifting device refers to the device used to clamp or support the power battery, and is installed below the Y-axis moving frame (see attached diagram). Figure 1 (In the Z-axis direction), this can be achieved using a mechanical gripper structure, which uses a third drive mechanism to realize lifting and lowering motion (see attached). Figure 1 The battery is grasped and released along the Z-axis. The X-axis moving frame refers to the frame that can move along the length of the battery swapping station (see attached diagram). Figure 1 The frame that moves along the X-axis can be specifically arranged with guide rails above the battery swapping room 1 and the parking eaves 2 (extending in the direction of the X-axis). Figure 1 The X-axis movable frame, mounted on a guide rail above the battery swapping room 1 and parking eaves 2 via rollers, moves along the length of the battery swapping station via a first drive mechanism. The X-axis movable frame has a certain length, and its extension direction is... Figure 1 The Y-axis direction. The Y-axis movable frame refers to the frame that can move along the width of the battery swapping station (see attached diagram). Figure 1 The frame, which moves along the Y-axis, can be movably connected to the X-axis moving frame using a structure of rollers and guide rails. Precise positioning along the width of the battery swapping station is achieved through a second drive mechanism. The first, second, and third drive mechanisms refer to the power units that drive the movement of each component. Specifically, they can be implemented using servo motors in conjunction with rack and pinion, hydraulic cylinders, or chain drives. Three-axis linkage control achieves three-dimensional coverage of the battery transport path.

[0058] Specifically, when a heavy truck parks in the battery swapping area, assuming the lifting device is inside the battery swapping compartment 1, the first drive mechanism moves the X-axis moving frame above the battery swapping channel 11. Then, the second drive mechanism moves the Y-axis moving frame from the battery swapping channel 11 to the parking battery swapping area outside the battery swapping compartment 1, positioning the lifting device above the battery loading / unloading point. Finally, the third drive mechanism lowers the lifting device to the battery installation position. After the power battery is picked up by the lifting device, the three-axis drive system works collaboratively to transport the battery along a predetermined path to the battery swapping station or buffer station. This three-dimensional motion system can cover the entire working area between the battery swapping compartment 1 and the parking eaves 2, achieving parallel access to batteries at multiple stations through coordinate positioning.

[0059] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
