[0001] The utility model relates to the technical field of split-box battery replacement, in particular to a split-box battery replacement device for a trailer. Background Art

[0002] A trailer is a vehicle towed by a car but without its own power drive device. It is a combination of a car (truck or tractor, forklift) and one or more trailers. A battery swap trailer is just an electric trailer that uses a battery swap mode. Its core feature is that it can quickly replenish electricity by replacing batteries, thereby solving problems such as long charging time and short driving range of trailers. Battery swap trailers are usually equipped with detachable battery packs. Users can quickly replace batteries at special battery swap stations to quickly restore the vehicle's usability. Due to the long mileage of trailers, in order to reduce the maintenance cost of the battery pack, the split-box battery swap technology is usually adopted. The split-box battery swap technology can optimize the battery pack energy management by managing independent battery modules. When a battery module in the battery pack fails or fails, it can be quickly replaced without affecting the use of the entire battery pack.

[0003] At present, when the power battery of a trailer is installed on the trailer frame, it is necessary to ensure that the power battery box will not move accidentally during the movement of the trailer, facilitate the replacement of the power battery box, and minimize the time required for the replacement of the power battery box. Based on the above requirements, a split-box battery replacement device for trailers is proposed. Utility Model Content

[0004] The purpose of the present utility model is to provide a split-box battery replacement device for a trailer to solve the problems raised in the above-mentioned background technology.

[0008] Preferably, protective pads are installed at the rear ends of the locking plates above and below the rotating screw through through holes, and a trigger switch is installed on the mounting rod behind the locking plate through a frame.

[0009] Preferably, a corrugated sleeve is installed in a sleeve-type manner on the surface of the rotating screw in front of the locking plate, and the front end of the corrugated sleeve is connected to the battery exchange frame.

[0010] Preferably, an adjustment groove is provided at the front end of the rotating screw, and an insertion groove is provided at the front end of the limiting frame, and the insertion groove extends to the surface of the rotating screw.

[0011] Preferably, a plurality of mounting grooves are arranged in a linear array at the upper end of the support rod, and a rotating shaft is rotatably connected inside the mounting grooves.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] like Figures 1 to 6 As shown, the present embodiment of the trailer-use split-box battery-changing device includes a trailer body 1, a battery-changing rack 2 is installed at the lower end of the trailer body 1, the number of the battery-changing racks 2 can be one or two, and when two battery-changing racks 2 are installed, they are symmetrically installed at the bottom of the trailer body 1, the battery-changing rack 2 is used to place multiple power battery boxes, and the battery-changing rack 2 can be disassembled, and a plurality of battery compartments 3 are arranged on the upper and lower ends of one end of the battery-changing rack 2. The number of battery compartments 3 on a battery-changing rack 2 can be two, four, six, etc. The battery compartment 3 is used to place the power battery box, and the internal size of the battery compartment 3 matches the size of the power battery box, a mounting rod 9 is installed at the rear of the battery-changing rack 2 between the upper and lower battery compartments 3, and a locking assembly is installed between the mounting rod 9 and the battery-changing rack 2, and the locking assembly is used to limit and lock the power battery box inside the battery compartment 3, and the locking assembly is used to limit and lock the power battery box inside the battery compartment 3. The component can simultaneously limit and lock two power battery boxes, effectively reducing the number of locking components installed, reducing the number of locking component operations required during battery replacement, and effectively speeding up the battery replacement efficiency. A limit frame 5 is installed on the surface of the battery replacement frame 2 in front of the locking component. The limit frame 5 is used to limit the locking component, which is convenient for the locking component to lock and unlock the power battery box. Support rods 6 are installed at the bottom ends of the battery compartments 3 on both sides of the locking component. The support rods 6 are used to support the power battery box. A plurality of guide wheels 7 are installed on the support rods 6. The setting of the guide wheels 7 reduces the movement resistance of the power battery box and the support rods 6, and changes the moving friction of the power battery box into rolling friction, which facilitates the movement of the power battery box. Side panels 8 are installed at both ends of the battery compartment 3. The setting of the side panels 8 facilitates limiting the two ends of the power battery box.

[0028] Specifically, the locking assembly includes a rotating screw 401, a threaded block 402 and a locking plate 403. The rotating screw 401 is installed between the mounting rod 9 and the battery exchange frame 2. The threaded block 402 is threadedly connected to the surface of the rotating screw 401. The front end of the threaded block 402 is located on the surface of the rotating screw 401 and a locking plate 403 is installed in a sleeve-type manner. The rotating screw 401 is rotated, and the rotating screw 401 drives the locking plate 403 to rotate through the threaded block 402. The locking plate 403 changes from a horizontal state to a vertical state, thereby realizing the limit locking of the power battery box by the locking plate 403, and the locking plate 403 can simultaneously limit and lock the upper and lower power battery boxes, effectively reducing the number of installed locking assemblies.

[0029] Furthermore, limiting plates 10 are respectively installed at the upper and lower ends of the rear end of the limiting frame 5, and the two limiting plates 10 are distributed diagonally. The locking plate 403 is located between the two limiting plates 10, and the thickness of the threaded block 402 is greater than the distance between the rear end of the limiting plate 10 and the mounting rod 9. The two limiting plates 10 are used to limit the locking plates 403. When the locking plates 403 contact the lower limiting plates 10, the locking plates 403 are in a horizontal state, and the locking plates 403 and the battery swapping frame 2 remain parallel, which will not affect the normal entry and exit of the power battery box from the battery compartment 3; when the locking plates 403 contact the upper limiting plates 10, the locking plates 403 are in a vertical state. In the vertical state, the locking plates 403 can limit the power battery boxes inside the upper and lower battery compartments 3 to prevent the power battery boxes from accidentally sliding out of the battery compartment 3, and the locking plates 403 will not move to the rear of the limiting plates 10, so as to prevent the limiting plates 10 from always following the rotating screw 401 to rotate and causing invalid locking.

[0030] Furthermore, protective pads 11 are installed at the rear ends of the locking plates 403 above and below the rotating screw 401 through through holes. The protective pads 11 are made of rubber material. When the locking plate 403 contacts the power battery box, the protective pads 11 are located between the locking plate 403 and the power battery box, which can avoid hard contact between the locking plate 403 and the power battery box, avoid wear on the surface of the power battery box, and ensure the beauty of the surface of the power battery box. A trigger switch 12 is installed on the mounting rod 9 behind the locking plate 403 through the frame. When the trigger switch 12 is pressed, a signal will be sent to prompt that the locking plate 403 has moved to the appropriate position, thereby avoiding the locking plate 403 from causing indentations on the power battery box, and playing a prompt trigger role.

[0031] Furthermore, a corrugated sleeve 13 is installed in a sleeve-type manner on the surface of the rotating screw 401 in front of the locking plate 403. The front end of the corrugated sleeve 13 is connected to the battery exchange frame 2. The corrugated sleeve 13 can be compressed. When the locking plate 403 rotates, the corrugated sleeve 13 will not rotate with it. The corrugated sleeve 13 can protect the surface of the rotating screw 401 to prevent rainwater and dust from condensing on the surface of the rotating screw 401, thereby avoiding affecting the normal driving of the rotating screw 401 on the threaded block 402.

[0032] Furthermore, an adjustment groove 14 is provided at the front end of the rotating screw 401, and an insertion groove 16 is provided at the front end of the limit frame 5. The insertion groove 16 extends to the surface of the rotating screw 401. The adjustment groove 14 is a concave groove. By using a specific tool to insert into the adjusting groove 14, the rotating screw 401 can be rotated. The setting of the insertion groove 16 is used to insert the tool into the adjusting groove 14.

[0033] Furthermore, a plurality of mounting grooves 17 are arranged in a linear array at the upper end of the support rod 6, and a rotating shaft 18 is rotatably connected inside the mounting groove 17. The guide wheel 7 is installed on the surface of the rotating shaft 18, and the surface of the guide wheel 7 extends to the top of the support rod 6, so that the guide wheel 7 can be rotated. At the same time, the guide wheel 7 can support the power battery box.

[0034] Furthermore, the front ends of the support rod 6 and the side panels 8 are provided with inclined surfaces 19 near the edges, and buffer blocks 20 are installed on both sides of the upper and lower sides of the rear end of the battery compartment 3. The buffer blocks 20 are made of rubber material. Due to the setting of the inclined surfaces 19, when the power battery box is placed into the battery compartment 3, the power battery box and the inclined surfaces 19 are in contact. The inclined surfaces 19 guide the power battery box, reduce the installation accuracy of the power battery box, and facilitate installation. The buffer blocks 20 are used to limit the rear of the power battery box and play a buffering role, effectively alleviating the inertial collision generated when the power battery box is pushed.

[0035] Furthermore, the upper battery compartment 3 and the lower battery compartment 3 are respectively on the same vertical line, and the rear end of the battery swap rack 2 behind the battery compartment 3 is respectively installed with a connecting plate 21, and the connecting plate 21 is installed on the trailer body 1 by bolts. By removing the bolts, the battery swap rack 2 can be removed. The lower ends of the two support rods 6 on the lower battery compartment 3 are both installed with a protective plate 15. The protective plate 15 is used to protect the bottom of the battery compartment 3 and protect against water and mud generated during the driving of the trailer to avoid contaminating the surface of the power battery box.

[0036] The usage method of this embodiment is as follows: the battery swap frame 2 is installed on the trailer body 1 through the connecting plate 21. When the power battery box is installed, the locking plate 403 remains in a horizontal state, and the locking plate 403 and the frame body on the battery swap frame 2 overlap. The locking plate 403 will not affect the movement of the power battery box. When the power battery box is placed inside the battery compartment 3, the bottom end of the power battery box contacts the guide wheel 7 on the support rod 6. When the power battery box moves, it drives the guide wheel 7 to rotate, effectively reducing the resistance to the movement of the power battery box. When the power battery box needs to be locked, the rotating screw 401 is driven to rotate by using a tool. The rotating screw 401 drives the locking plate 403 to move through the threaded block 402. During this process, one end of the locking plate 403 moves from the lower limit plate 10 contact changes to contact with the upper limit plate 10, and the locking plate 403 changes from a horizontal state to a vertical state. As the rotating screw 401 continues to rotate, the rotating screw 401 drives the locking plate 403 to move toward the power battery box, and the protective pad 11 on the locking plate 403 contacts the power battery box to lock the power battery box. At the same time, the locking plate 403 presses the trigger switch 12, and the trigger switch 12 controls the prompt element to prompt. The upper and lower ends of the locking plate 403 can respectively lock and limit the power battery boxes inside the upper and lower battery compartments 3. When the power battery box is taken out and replaced, use a tool to drive the rotating screw 401 to rotate in the reverse direction to change the locking plate 403 from a vertical state to a horizontal state, and the power battery box can be replaced.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
