It is a power supply device for the product to discharge to the outside, and it often needs to be disassembled for charging and energy replenishment.

[0003] Due to the large size of large equipment, the battery packs therein are installed at a high height. At the same time, due to the heavy weight of the battery packs, they have previously required pure manpower to lift and disassemble them.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] like Figure 1 As shown, a battery pack installation device provided by the present invention includes: a walking mechanism 1, a lifting mechanism 2 and two adjustment brackets, and the two adjustment brackets can be set to different specifications and sizes; in this embodiment, the battery pack is divided into a small battery 6 and a large battery 7, and the small battery 6 corresponds to the small battery adjustment bracket 4, and the large battery 7 corresponds to the large battery adjustment bracket 5.

[0045] The lifting mechanism 2 is installed on the walking mechanism 1 , and an upper platform 3 is installed on the top of the lifting mechanism 2 . The lifting mechanism 2 can adopt a hydraulic scissor-type lifting mechanism 2 .

[0046] Among them, Figure 8 As shown, the adjustment bracket includes a first translation mechanism 41, a rotation mechanism 42, a height adjustment mechanism 43 and a second translation mechanism 44 which are arranged in sequence from bottom to top.

[0047] The first translation mechanism 41 is slidably connected to the upper platform 3 along a first direction, and the rotating mechanism 42 is slidably connected to the first translation mechanism 41; the height adjustment mechanism 43 is arranged on the rotating mechanism 42; the second translation mechanism 44 is slidably connected to the height adjustment mechanism 43 along a second direction perpendicular to the first direction.

[0048] Among them, the walking mechanism 1 is used to realize the rapid transportation of the battery pack by manual pushing on the ground, the lifting mechanism 2 is used to lift the battery so that its height matches the onboard installation position, and the adjustment bracket is used to quickly adjust the position of the battery pack equipment so that it matches the installation position height of the large battery pack. The battery pack installation vehicle device has a total of 5 degrees of freedom adjustment mechanisms, which can quickly and efficiently complete the rapid installation and removal of a certain special large battery pack.

[0049] After the traveling mechanism 1 is moved to the designated position, the lifting mechanism 2 installed on the traveling mechanism 1 can drive the adjusting bracket thereon to rise and fall, lift the battery pack to the designated height, and then fine-tune the position through the first translation mechanism 41 and the second translation mechanism 44. At the same time, the height adjustment mechanism 43 is used to compensate for the inaccurate height fine-tuning of the lifting mechanism 2. As a whole, an adjustment mechanism with 5 degrees of freedom is formed to achieve the adjustment of the spatial position. The battery on the adjusting bracket is aligned with the hatch of the onboard battery placement compartment, so that the rapid installation and disassembly of a special large battery pack can be completed quickly and efficiently.

[0050] Among them, Figure 5 As shown, the lifting mechanism 2 includes: a scissor arm assembly and a lifting cylinder 22, wherein the scissor arm assembly is specifically a double scissor arm, specifically including a plurality of scissor arms 23 hinged in sequence, a lateral stabilizer bar 24 is connected between the two groups of scissor arms 23, and both ends of the lateral stabilizer bar 24 are connected and fixed to the scissor arms 23 by hinge pins 26.

[0051] The fixed end at the bottom of the scissor arm assembly is hinged to the walking mechanism 1, and the movable end at the bottom of the scissor arm assembly is slidably connected to the walking mechanism 1. Specifically, Figure 6 As shown, a roller 21 is installed at the movable end at the bottom of the scissor arm assembly, and the roller 21 is slidably matched in the walking mechanism 1, as shown in FIG. Figure 7 As shown, the movable end at the top of the scissor arm assembly is hinged with a slider 28, and a linear guide 27 matching the slider 28 is installed at the bottom of the upper platform 3. In the past, when the scissor arms on the market were raised to the highest point, the scissor lifting position was greatly offset, and when the upper rollers 21 and the upper platform 3 were not constrained in place on the left and right, a large shake occurred. In order to prevent the upper platform 3 from shaking when the scissor arm assembly is raised or lowered, a linear guide 27 and a slider 28 installed at the bottom of the upper platform 3 are connected to the movable end at the top of the scissor arm assembly. Through finite element analysis and comparison, the load-bearing and stability of this structure are significantly better than those of the roller 21 support structure, and it is not easy to shake.

[0052] The tail end of the lifting cylinder 22 is hinged to the walking mechanism 1, and the output end of the lifting cylinder 22 is hinged to the scissor arm assembly.

[0053] The lifting cylinder 22 is also connected to a split hand pump 14. The lifting cylinder 22 and the split hand pump 14 are connected by a high-pressure oil pipe. The handle is pressed downward to control the cylinder to lift. The tail of the cylinder is hinged and fixed in the middle of the frame 11 of the walking mechanism 1, and one end is hinged to the thrust ear 25. The thrust ear 25 is fixed on the lower scissor arm 23 to drive the scissor arm 23 to move. One side of the top of the scissor arm 23 is hinged and fixed on the upper platform 3, and the other side is connected to the upper platform 3 through a linear guide 27 and a slider 28. By continuously pressing the split hand pump 14, the scissor platform is lifted as the angle of the scissor arm 23 changes. In addition, the split hand pump 14 uses mature matching components on the market, which are provided with a refueling port and a load-unloading pedal. Lightly stepping on the load-unloading pedal can control the cylinder to retract, thereby achieving the descent of the scissor platform.

[0054] like Figure 2 , 3 As shown, it also includes a lifting self-locking mechanism 16, which includes a screw 163 screwed on the walking mechanism 1, and the active end of the screw 163 is close to or away from the movable end at the bottom of the scissor arm assembly. By rotating the screwed screw 163, the screw 163 is screwed in and out, and its end is controlled to be close to or away from the movable end at the bottom of the scissor arm assembly as the active end, which is used to support the scissor arm assembly. The rotating screw 163 can play a supporting role when the scissor arm assembly is at different heights.

[0055] like Figure 2 As shown, the walking mechanism 1 includes: a frame 11, universal casters 12 and a traction handrail 15.

[0056] The vehicle frame 11 is a rectangular frame, and is provided with a plurality of limit buffer pads 17 for contacting the upper platform 3 . There are four limit buffer pads 17 , which are located at the four corners of the top of the vehicle frame 11 and can be rubber pads.

[0057] Four universal casters 12 are installed at the four corners of the frame 11, and are in contact with the ground through the four universal casters 12. A traction handrail 15 is detachably connected to one side of the frame 11. The traction handrail 15 is connected and fixed to the frame 11 through a locking pin 18. After removing the locking pin 18, the traction handrail 15 can be removed.

[0058] At least one parking assembly is provided on the side of the frame 11 away from the traction handrail 15, and the parking assembly includes two parking feet 13 screwed on both sides of the frame 11. The parking feet 13 can not only play a parking support role, but also can cooperate with the two universal casters 12 on the side close to the traction handrail 15 to achieve the pitch angle adjustment of the entire walking mechanism 1, so as to match the installation inclination angle of the equipment.

[0059] Among them, Figure 4As shown, the parking anchor 13 includes a ball-head trapezoidal screw 132, the top of the ball-head trapezoidal screw 132 is connected to a parking handle 131, the top ball is connected to a ball-head base plate 133, and a base pad 134 is provided at the bottom of the ball-head base plate 133. The ball-head base plate 133 cooperates with the ball-head trapezoidal screw 132 to adapt to various road conditions and ensure stable support. When parking, a foot brake is provided on the universal caster 12. The foot brake is first stepped on, and then the extension length of the screw 163 is adjusted by the parking handle 131, so that the walking mechanism 1 can be adjusted forward and backward in pitch to match the installation inclination angle of the equipment.

[0060] like Figure 3 As shown, the lifting self-locking mechanism 16 also includes a mounting base plate 162, the screw 163 is screwed on the mounting base plate 162, the screw 163 vertically penetrates and is screwed in the center of the mounting base plate 162, one end of the screw 163 is connected to a self-locking adjustment hand wheel 161, and the other end is connected to a self-locking top block 164, and the mounting base plate 162 is provided with a waist-shaped hole 165 for connecting with the walking mechanism 1, and the waist-shaped holes 165 on both sides are horizontally arranged, and fasteners such as butterfly bolts are passed through the waist-shaped holes 165 to fix the walking mechanism 1. The mounting base plate 162 is fixed on the frame 11 of the traveling mechanism, and the waist-shaped hole 165 is used to adjust the position of the screw rod 163 to correspond to or be misaligned with the moving path of the movable end at the bottom of the scissor arm assembly, that is, the mounting base plate 162 together with the screw rod 163 can be translated left and right through the waist-shaped hole 165, and the end of the screw rod 163 can be aligned with the movable end at the bottom of the scissor arm assembly or deviated from the movable end. When there is a support requirement, the screw rod 163 is adjusted to be aligned, and when there is no support requirement, the screw rod 163 is adjusted to deviate.

[0061] like Fig. 9 , 10 As shown, the first translation mechanism 41 includes: a moving base plate 411 , a trapezoidal lead screw 416 , a nut seat 414 and a locking quick clamp 413 .

[0062] A guide rail slider 419 arranged along the first direction is installed at the bottom of the movable base plate 411. The movable base plate 411 is slidably connected to the upper platform 3 through the guide rail slider 419 and can slide back and forth along the first direction. Specifically, limit stops 418 are provided at both ends of the guide rail to prevent the movable base plate 411 from slipping off the guide rail.

[0063] A hollow area is formed at the bottom of the upper platform 3 corresponding to the movable bottom plate 411 , and a connecting plate 415 is connected to the bottom of the movable bottom plate 411 . The connecting plate 415 extends into the lower part of the upper platform 3 through the hollow area.

[0064] The trapezoidal lead screw 416 is rotatably connected to the upper platform 3 along the first direction. Specifically, the trapezoidal lead screw 416 is rotatably connected to the side of the upper platform 3 and extends into the bottom of the upper platform 3. The distal end of the trapezoidal lead screw 416 is rotatably connected to the bottom of the upper platform 3 through a rear support block 417. The proximal end of the trapezoidal lead screw 416 is connected to the first adjusting handwheel 412. The nut seat 414 is connected to the trapezoidal lead screw 416. The nut seat 414 is connected to a connecting plate 415 that passes through the upper platform 3 and is fixed to the movable base plate 411. As the trapezoidal lead screw 416 rotates, the nut seat 414 thereon can be driven to reciprocate axially along the trapezoidal lead screw 416, thereby driving the connecting plate 415, and then driving the movable base plate 411 to reciprocate along the first direction on the guide rail.

[0065] The locking quick clamp 413 is fixed on the upper platform 3, and the locking quick clamp 413 is sleeved on the outer periphery of the trapezoidal screw rod 416 to limit the rotation of the trapezoidal screw rod 416. Since the locking quick clamp 413 is fixed on the upper platform 3, after the locking quick clamp 413 clamps the trapezoidal screw rod 416, it can prevent the trapezoidal screw rod 416 from rotating, thereby playing a self-locking role.

[0066] To achieve angle adjustment, Fig.11 , 12 As shown, a rotating mechanism 42 is also included, and the rotating mechanism 42 includes: a rotating adjustment base plate 421 and a fixing bolt 422 .

[0067] The center of the rotating adjustment base plate 421 is rotatably connected to the top of the first translation mechanism 41, specifically connected to the center of the top of the moving base plate 411 of the first translation mechanism 41, and two bearings are arranged between the two. The centers are connected by a hinge hole screw 425, and the outer periphery of the hinge hole screw 425 is sleeved with a deep groove ball bearing 424, which acts as a rotating center axis, and a thrust ball bearing 423 is arranged between the rotating adjustment base plate 421 and the moving base plate 411, which mainly bears the axial load and is used to bear the load of the upper mechanism; The rotation adjustment base plate 421 is provided with an arc hole 426 with its center as the center of the circle, and the fixing bolt 422 passes through the arc hole 426 and is connected to the top of the first translation mechanism 41. The fixing bolt 422 can be a butterfly bolt, and the rotation adjustment base plate 421 is fastened to the moving base plate 411 by tightening the butterfly bolt. When rotation is required, loosen the butterfly bolt, manually adjust the rotation, and tighten the butterfly bolt after adjustment to achieve rapid rotation adjustment.

[0068] In order to improve the precision of height adjustment, Fig.13 , 14 As shown, it also includes a height adjustment mechanism 43, which includes a worm gear mechanism 433, a height fine-tuning base plate 431 and a guide device.

[0069] The worm gear mechanism 433 is arranged at the top of the rotating mechanism 42, specifically, it is fixed on the rotating adjustment base plate 421, the worm in the worm gear mechanism 433 extends upward as the output end, and the height fine-tuning base plate 431 is arranged on the top worm of the worm gear mechanism 433; its extending shaft is connected to the height adjustment handwheel 432 through a keyway.

[0070] Because the upper battery needs to move sideways when it is installed, the height fine adjustment needs to have the ability to resist tilting, so the guide device is set between the height fine adjustment base plate 431 and the rotating mechanism 42. A set of guide devices is set on the left and right sides of the height fine adjustment base plate 431; The guide device includes a guide shaft seat 435 and a guide shaft 434. The guide shaft seat 435 is installed on the height fine-tuning base plate 431, and the matching guide shaft 434 is fixed on the rotation adjustment base plate 421. By setting two sets of guide devices, the stability of the overall structure of the height fine-tuning mechanism is improved.

[0071] In this embodiment, Fig.15 , 16 As shown, the second translation mechanism 44 includes: a slide rail, a tray 441 and a locking pin 443 .

[0072] The slide rail adopts a heavy-duty drawer slide rail 442, which is arranged at the top of the height adjustment mechanism 43 along the second direction, specifically at the top of the height fine-tuning base plate 431, and the tray 441 is installed on the slide rail. Specifically, the moving end part of the heavy-duty drawer slide rail 442 is installed at the bottom of the tray 441, and the fixed end part of the slide rail is installed on the height fine-tuning base plate 431. The working stroke of the slide rail is not less than 200 mm, which meets the lateral movement and loading requirements of the battery. The three sides of the tray 441 are bent upward to form a convex edge 447, and the convex edge 447 is provided with a pin hole 448 corresponding to the hinge pin 51 on the battery pack. Since the battery has hinge pins 51 on both sides, it is used to fix it on the battery placement rack in the cabin. It is agreed that the battery can be fixed on the tray 441 by correspondingly inserting the hinge pin 51 and the pin hole 448 to ensure that the equipment is firmly fixed when it is pushed and driven.

[0073] A handle 445 is also provided on the convex edge 447 for an operator to conveniently hold and push the tray 441 .

[0074] The locking pin 443 is connected to the tray 441, and a plurality of positioning pin holes 449 matching the locking pin 443 are arranged at intervals along the second direction on the top of the height adjustment mechanism 43. When the tray 441 is moved close to the battery compartment wall under the support of the heavy-duty drawer slide rail 442 through the handles 445 on both sides, a circle of U-shaped edging 446 is provided at the front end of the battery box bracket to avoid damaging the metal paint surface of the battery compartment wall. The edging is provided on one side of the tray 441 where the convex edge 447 is not provided. The edging can prevent the battery from being hit hard when entering and exiting through this side. At this time, the locking pin 443 can be inserted into the nearest positioning pin hole 449 to achieve locking of the tray 441. Furthermore, a nylon slide plate 444 is provided on the top surface of the tray 441, which has a small friction coefficient, so that the operator can easily push the battery pack in the bracket into the cabin.

[0075] Specific operation steps: when the lifting mechanism is lowered to the lowest position, put the large battery and the small battery into the tray in the second translation mechanism respectively, insert the hinge pin into the pin hole to fix the battery in the tray, push the walking mechanism to the target position by pulling the handrail, and then fix it by the foot brake on the universal caster, and then extend the ball head trapezoidal screw by turning the parking handle, so that the ball head bottom plate contacts the ground, and the parking foot cooperates with the universal caster on the other side to adjust the pitch angle of the walking mechanism, and lift the upper platform to a suitable height through the lifting mechanism, use the self-locking top block of the screw in the lifting self-locking mechanism to resist the roller, and use the friction between the screw and the mounting bottom plate to form self-locking, which supports the lifting mechanism and forms self-locking; adjust the front and rear position of the upper battery through the first translation mechanism, specifically by turning the first adjustment handwheel , drive the nut seat and the connecting plate to move on the trapezoidal screw rod, and adjust the movable bottom plate to the appropriate position; adjust the worm gear mechanism through the height adjustment handwheel to fine-tune the height fine-adjustment bottom plate to the appropriate height and align it with the hatch of the placement compartment; loosen the fixing bolts and rotate the rotation adjustment bottom plate to the appropriate angle, and then tighten the fixing bolts; finally, take out the locking pin from the locating pin hole, and the tray can move along the drawer slide together with the battery on it, align the end of the tray without a convex edge with the hatch position of the placement compartment and move it closer, wait for the tray to slide to the appropriate position, and re-use the locking pin to insert the lower locating pin hole to fix the tray position, loosen the lock of the hinge pin and the pin hole, and push the battery into the placement compartment. The nylon slide plate reduces friction during the pushing process, and then gradually retract the adjustment bracket and the lifting mechanism to reload the battery.
