Description

Technical Field

[0001] This utility model relates to the field of heavy truck battery pack replacement technology, and in particular to a floating battery pack bridge. Background Technology

[0002] Existing battery pack replacement devices for battery-swapping heavy-duty trucks are shown in patent application number CN202311029642.X, and existing charging racks for battery-swapping heavy-duty trucks are shown in patent application number CN202420159933.4. The simplified structural principles of the replacement device and charging rack are as follows: Figure 10 and Figure 11 As shown, the replacement device includes an adjusting seat 91, a movable seat 92, a first roller 93, a first linear driver (not shown in the figure), and a second linear driver (not shown in the figure). The movable seat 92 is slidably connected to the upper side of the adjusting seat 91 and is driven by the first linear driver. The first roller 93 is rotatably connected to the upper side of the movable seat 92 and is used to support and move the battery pack 94. The second linear driver is mounted on the movable seat 92 and is used to drive the battery pack 94 to move back and forth on the first roller 93.

[0003] The charging rack includes a welded frame 95 fixed to the side of the heavy truck, and a battery compartment for accommodating the battery pack is formed inside the welded frame. The bottom of the battery compartment is rotatably connected to a second roller 96 to facilitate the entry and exit of the battery pack 94 into and out of the battery compartment.

[0004] The existing battery pack replacement device performs the following process when inserting the battery pack into the battery compartment: Figure 10 As shown, initially, the heavy truck is parked on one side of the replacement device, and the battery pack 94 to be installed is placed on the upper side of the moving seat 92. The moving seat 92 is basically located directly above the adjusting seat 91, and the upper sides of the first roller 93 and the second roller 96 are basically flush. Figure 11 As shown, the first linear actuator drives the moving seat 92 to approach the battery compartment. One end of the moving seat 92 is suspended in the air. The second linear actuator drives the battery pack 94 to move along the first roller 93 towards the battery compartment. Existing battery packs used for heavy trucks generally weigh several hundred kilograms. When the battery pack moves to the suspended end of the moving seat 92, the suspended end of the moving seat 92 is prone to drooping, which causes a height difference between the first roller 93 on the upper side of the suspended end of the moving seat 92 and the second roller 96 in the battery compartment. This affects the insertion of the battery pack 94. In severe cases, the battery pack 94 is prone to getting stuck at the battery compartment opening and cannot enter the battery compartment. Utility Model Content

[0005] To address the shortcomings of existing battery pack replacement devices where the suspended end of the moving seat tends to sag when the battery pack moves to its suspended position, this invention proposes a battery pack bridge to prevent the suspended end of the moving seat from sag, thus allowing the battery pack to be smoothly installed into the battery compartment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A floating battery pack bridge includes an end plate, a support plate, a follower plate, and a locking mechanism. The end plate is fixedly connected to the front end of a movable seat. The support plate is horizontally arranged on the front side of the end plate. The rear end of the support plate is hinged to the end plate. The front end of the support plate is used to support a charging rack. The upper end of the follower plate is fixedly connected to the support plate. The lower end of the follower plate is attached to the front side of the end plate. The locking mechanism is fixedly connected to the end plate and can press the follower plate onto the end plate or release the follower plate.

[0008] With the above settings, firstly, when the front end of the mobile seat approaches the charging rack, the front end of the mobile seat can be supported on the charging rack by the support plate to prevent the front end of the mobile seat from sagging; secondly, the locking mechanism can release the follower plate, and when the charging rack floats up, the support plate can float up accordingly to prevent damage to the cable tray.

[0009] Furthermore, the locking mechanism includes a pressure plate and a linear actuator. The pressure plate is located on the front side of the lower end of the follower plate. The linear actuator has a self-locking function and is fixedly connected to the rear side of the end plate. Both the end plate and the follower plate are provided with through holes. The output shaft of the linear actuator is connected to the pressure plate through the through holes to drive the pressure plate to move back and forth.

[0010] With the above settings, the linear actuator presses or releases the follower plate by driving the front and rear pressure plates.

[0011] Furthermore, the linear actuator includes a fixed base, a guide rail, a slider, a lead screw, a motor, and the aforementioned output shaft. The fixed base is fixedly connected to the rear side of the end plate, the slider is slidably connected to the lower side of the fixed base via the guide rail, the slider is fixedly connected to the output shaft, the motor is fixedly connected to the fixed base and is driven by the lead screw, the lead screw extends in the front-rear direction and is threadedly connected to the slider.

[0012] Furthermore, each linear driver is equipped with two of the aforementioned output shafts, and the slider is connected to the pressure plate via the two output shafts.

[0013] With the above settings, the pressure plate is more stable when pressing the follower plate.

[0014] Furthermore, the linear actuator also includes a first fixing plate and a second fixing plate disposed on the front and rear sides of the slider. The first fixing plate and the second fixing plate are both fixedly connected to the lower side of the fixed base. The motor is fixedly connected to the rear side of the second fixing plate, and the lead screw is rotatably connected between the first fixing plate and the second fixing plate.

[0015] With the above configuration, the lead screw is stably rotatably connected to the lower side of the fixed seat via the first fixed plate and the second fixed plate.

[0016] Furthermore, there are two end plates, which are respectively set on the left and right sides of the front end of the moving seat. The support plate is a rectangular structure, and the length of the support plate is parallel to the left and right direction of the moving seat. There are two follower plates, which correspond one-to-one with the two end plates and are respectively set on the left and right ends of the support plate. Each follower plate has a pressure plate driven by the aforementioned linear driver on its front side.

[0017] With the above setup, the support plate is locked to the pressure plate at both ends by the follower plates, which improves the support stability and effectively prevents the front end of the moving seat from sagging.

[0018] Furthermore, the cable tray also includes ear plates and a rotating shaft. The ear plates are provided at both ends of the support plate. The ear plates are fixedly connected to the front side of the end plate, and the rotating shaft is fixedly connected between the ear plates. The rotating shaft passes through the support plate and is rotatably connected to the support plate.

[0019] With the above configuration, the support plate is hinged to the ear plate and the end plate via a rotating shaft. Attached Figure Description

[0031] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0032] like Figures 1 to 9 As shown, a floating battery pack bridge includes an end plate 2, a support plate 3, a follower plate 4, and a locking mechanism 5. The end plate 2 is fixedly connected to the front end of the movable seat 6. The support plate 3 is horizontally arranged on the front side of the end plate 2. The rear end of the support plate 3 is hinged to the end plate 2. The front end of the support plate 3 is used to support the charging rack 12. The upper end of the follower plate 4 is fixedly connected to the support plate 3. The lower end of the follower plate 4 is attached to the front side of the end plate 2. The locking mechanism 5 is fixedly connected to the end plate 2 and can press the follower plate 4 onto the end plate 2 or release the follower plate 4.

[0033] With the above settings, firstly, when the front end of the movable seat 6 is close to the charging rack, the front end of the movable seat 6 can be supported on the charging rack by the support plate 3 to prevent the front end of the movable seat 6 from sagging; secondly, the locking mechanism 5 can release the follower plate 4, and when the charging rack floats up, the support plate 3 can float up accordingly to prevent damage to the cable tray.

[0034] The cable tray of this application is used in existing battery pack replacement devices, so that the battery pack 8 can be smoothly entered into the charging rack under the action of the replacement device. The replacement device and the charging rack can be referred to in the background art.

[0035] Figures 1 to 4 As shown, the replacement device includes an adjusting seat 7 and a movable seat 6. The movable seat 6 is basically located directly above the adjusting seat 7 and can slide back and forth. When replacing the battery of a heavy truck, the battery pack 8 to be installed is placed on the upper side of the movable seat 6, and the charging rack is placed on the front side of the battery pack 8 and directly facing the battery pack 8. The end plate 2 of the bridge frame is vertically fixedly connected to the front side of the movable seat 6, the support plate 3 is horizontal, and the upper side of the support plate 3 is basically flush with the upper side of the movable seat 6. The upper end of the follower plate 4 is fixedly connected to the lower rear end of the support plate 3, and the lower end of the follower plate 4 abuts against the front side of the support plate 3. The locking mechanism 5 locks the lower end of the follower plate 4 onto the support plate 3. At this time, the support plate 3 is locked and cannot rotate up and down. Figure 7 As shown, when the battery swapping begins, the movable seat 6 first moves towards the charging rack along the adjusting seat 7. The front end of the movable seat 6 is suspended in the air, and the bridge is located at the suspended end of the movable seat 6, moving towards the charging rack synchronously with the movable seat 6. After the support plate 3 of the bridge is attached to the charging rack, the movable seat 6 stops moving. At this time, the charging rack itself supports the front end of the movable seat 6 through the bridge, and the front end of the movable seat is no longer suspended in the air. When the battery pack 8 moves towards the charging rack along the movable seat 6 and reaches the front end of the movable seat 6, the front end of the movable seat 6 will not droop, so that the battery pack 8 can smoothly enter the charging rack and complete the installation of the battery pack 8.

[0036] like Figure 8 and Figure 9 As shown, after the locking mechanism 5 releases the follower plate 4, the support plate 3 can rotate upward. At this time, the battery pack 8 with insufficient power on the heavy truck can be removed by the replacement device. The specific process is as follows: the unloaded moving seat 6 moves close to the charging frame along the adjusting seat 7. After the support plate 3 is placed horizontally on the charging frame, the replacement device pulls the battery pack 8 from the charging frame to the moving seat 6. Since the weight of the battery pack 8 is reduced on the heavy truck, the load on the heavy truck becomes lighter. The charging frame fixed on the heavy truck floats up, and the front end of the support plate 3 floats up accordingly to prevent the support plate 3 from being broken by the floating charging frame.

[0037] As one implementation, the locking mechanism 5 includes a pressure plate 51 and a linear actuator 52. The pressure plate 51 is located on the front side of the lower end of the follower plate 4. The linear actuator 52 has a self-locking function and is fixedly connected to the rear side of the end plate 2. Both the end plate 2 and the follower plate 4 are provided with through holes 9. The output shaft 526 of the linear actuator 52 is connected to the pressure plate 51 through the through hole 9 and is used to drive the pressure plate 51 to move back and forth.

[0038] With the above settings, the linear actuator 52 presses or releases the follower plate 4 by driving the front and rear pressure plates 51.

[0039] The linear actuator 52 of this application extends in the front-to-back direction. The linear actuator 52 can be a nut and screw 524 structure or a cylinder or other actuator with a self-locking function. The rear end of the linear actuator 52 is fixedly connected to the rear side of the end plate 2, and the front end is connected to the pressure plate 51 through the through hole 9. When the linear actuator 52 drives the pressure plate 51 to move backward, the pressure plate 51 presses the lower end of the follower plate 4 onto the end plate 2. At this time, the support plate 3 is locked to the pressure plate 51 through the follower plate 4, and the support plate 3 cannot rotate up and down. When the linear actuator 52 drives the pressure plate 51 to move forward, the pressure plate 51 releases the lower end of the follower plate 4. At this time, the front end of the support plate 3 can rotate upward.

[0040] In one implementation, the linear actuator 52 includes a fixed base 521, a guide rail 522, a slider 523, a lead screw 524, a motor 525, and the aforementioned output shaft 526. The fixed base 521 is fixedly connected to the rear side of the end plate 2. The slider 523 is slidably connected to the lower side of the fixed base 521 via the guide rail 522. The slider 523 is fixedly connected to the output shaft 526. The motor 525 is fixedly connected to the fixed base 521 and is drivenly connected to the lead screw 524. The lead screw 524 extends in the front-rear direction and is threadedly connected to the slider 523.

[0041] In this application, the slider 523 can slide back and forth under the fixed base 521. The lead screw 524 and the output shaft 526 both extend in the front-back direction. The motor 525 is located at the rear end of the lead screw 524. When the motor 525 drives the lead screw 524 to rotate, the lead screw 524 and the slider 523 rotate relative to each other, and the slider 523 moves forward or backward. The slider 523 drives the pressure plate 51 to move synchronously through the output shaft 526 to press or release the follower plate 4. After the motor stops, the lead screw and the slider will not rotate relative to each other, achieving self-locking.

[0042] In one implementation, each linear actuator 52 is provided with two of the aforementioned output shafts 526, and the slider 523 is connected to the pressure plate 51 via the two output shafts 526.

[0043] With the above settings, the pressure plate 51 presses the follower plate 4 more stably.

[0044] As one implementation, the linear actuator 52 also includes a first fixing plate 527 and a second fixing plate 528 disposed on the front and rear sides of the slider 523. The first fixing plate 527 and the second fixing plate 528 are both fixedly connected to the lower side of the fixing base 521. The motor 525 is fixedly connected to the rear side of the second fixing plate 528. The lead screw 524 is rotatably connected between the first fixing plate 527 and the second fixing plate 528.

[0045] With the above configuration, the lead screw 524 is stably rotatably connected to the lower side of the fixed base 521 via the first fixed plate 527 and the second fixed plate 528.

[0046] As one implementation, there are two end plates 2, which are respectively set on the left and right sides of the front end of the movable seat 6. The support plate 3 is a rectangular structure, and the length direction of the support plate 3 is parallel to the left and right direction of the movable seat 6. There are two follower plates 4, which correspond one-to-one with the two end plates 2, and are respectively set on the left and right ends of the support plate 3. Each follower plate 4 has a pressure plate 51 driven by the linear driver 52 on its front side.

[0047] With the above settings, the support plate 3 is locked to the pressure plate 51 by the follower plates 4 at both ends, which improves the support stability and effectively prevents the front end of the moving seat 6 from sagging.

[0048] As one implementation, the cable tray also includes ear plates 10 and rotating shafts 11. The ear plates 10 are provided at both ends of the support plate 3. The ear plates 10 are fixedly connected to the front side of the end plate 2. The rotating shaft is fixedly connected between the ear plates 10. The rotating shaft passes through the support plate 3 and is rotatably connected to the support plate 3.

[0049] With the above configuration, the support plate 3 is hinged to the ear plate 10 and the end plate 2 via the rotating shaft.

[0050] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
