Description

Technical Field

[0001] The utility model relates to a battery bracket, and more specifically, to a battery bracket for battery replacement and a vehicle for battery replacement. Background Art

[0002] With the improvement of electric technology and the reduction of battery costs, more and more engineering machinery products are powered by batteries. Battery drive has the advantages of lower TCO and more environmental protection. However, the problem of battery recharge restricts the development of battery-driven equipment, and the recharge method of replaceable batteries has become one of the effective solutions to solve the problem of recharging electric-driven engineering machinery products. Truck battery replacement can be completed at a battery replacement station, but the working scenes of engineering machinery products change quickly, the product driving speed is slow, the appearance varies greatly, and the cost of building a battery replacement station is high; especially when constructing relatively suburban construction sites, battery replacement becomes a difficulty in the industry.

[0003] When replacing batteries at the work site, construction machinery is usually replaced by a battery replacement truck or forklift. Battery replacement trucks have high requirements for battery replacement sites, poor scene applicability, and low battery replacement efficiency. When using a forklift to replace batteries, the battery needs to be placed on the ground during replacement, which is easy to contaminate the battery replacement interface; the battery replacement efficiency is low.

[0030] The specific implementation scheme is described below with reference to the accompanying drawings.

[0031] like Figure 1 Figure 2 As shown, the battery bracket for battery replacement includes a main bracket 10 and two protective side rails 20.

[0032] The main bracket 10 has a support surface for placing and carrying the power battery 100, and a mounting bracket 30 for fixedly connecting to the bracket-carrying vehicle is fixedly installed at the rear.

[0033] The two protective side rails 20 are respectively rotatably mounted on the left and right sides of the main bracket 10 at their lower parts through a hinged flipping mechanism; each protective side rail 20 can flip between a horizontal state and a vertical state and can be maintained in a horizontal state or a vertical state; the two protective side rails 20 are flush with the supporting surface of the main bracket 10 when in a horizontal state, and are perpendicular to the supporting surface of the main bracket 10 when in a vertical state.

[0034] The main bracket 10 includes two parallel side beams 12 arranged longitudinally, two main beams 11 arranged in parallel between the two side beams 12, and a plurality of cross beams 13 arranged at intervals in the front-to-rear direction and fixedly connected to the side beams 12 and the main beams 11. The protective side rails 20 are hinged to the corresponding side beams.

[0035] The main beam 11 is a square tube structure, or an I-beam structure or a channel steel structure; the cross beam 13 and the side beam 12 are plate-shaped and arranged vertically. The cross beam 13, the main beam 11 and the side beam 12 are welded in a crisscross manner to form a grid structure, so as to have sufficient thickness and reduce weight while meeting the strength requirements.

[0036] Optionally, the main bracket 10 further includes a bearing plate 14, which is fixed to and covers the cross beam 13. The bearing plate 14 is fixedly welded to the cross beam 13, so as to facilitate placing the power battery 100 thereon, and also to enhance the bearing capacity of the main bracket 10.

[0037] The protective side rail 20 includes an upper cross bar 21 , a lower cross bar 22 , a plurality of vertical bars 23 arranged in parallel and fixedly connected at both ends to the upper cross bar 21 and the lower cross bar 22 , and a hinged flip mechanism connected to the lower cross bar 22 .

[0038] The hinged flipping mechanism includes a hinged mechanism 40 connecting the main bracket 10 and the protective side rail 20 , and a flipping driving mechanism 50 for pushing the protective side rail 20 to flip up and down around the hinged mechanism 40 .

[0039] like Figure 2 As shown, the hinge mechanism 40 includes a hinge pin 41, a first hinge plate 42, and a second hinge plate 43. The first hinge plate 42 is welded to the outer side surface of the side beam 12 (i.e., the left side surface of the left side beam and the right side surface of the right side beam). The second hinge plate 43 is welded to the lower cross bar 22, and the first hinge plate 42 and the second hinge plate 43 are rotatably connected through the hinge pin 41.

[0040] The flipping driving mechanism 50 includes a hydraulic cylinder 51, a first hinge seat 52 and a second hinge seat 53 connected to both ends of the hydraulic cylinder 51, and the first hinge seat 52 and the second hinge seat 53 are respectively fixed on the cross beam 13 and the lower cross bar 22. The hydraulic cylinder 51 can push the protective side rail 20 to flip up and down by telescoping.

[0041] Optionally, the hydraulic cylinder 51 is arranged between two adjacent cross beams 13 . To avoid interference between the side beam 12 and the hydraulic cylinder 51 during the upside-down flipping of the protective side rail 20 , a cylinder avoidance gap 15 for avoiding the hydraulic cylinder 51 is provided on the side beam 12 .

[0042] exist Figure 1 Figure 2 In the battery bracket shown in the figure, the second hinge plate 43 has two mutually perpendicular limiting abutting surfaces, which can respectively abut against the outer side surface of the corresponding side beam 12 when the protective side rail 20 is in a horizontal state and a vertical state. Figure 1 As shown, its first limiting abutting surface abuts against the outer side surface of the corresponding side beam, limiting the position of the protective side rail 20 to prevent the protective side rail 20 from further turning downward, thereby keeping the protective side rail 20 in a horizontal state and flush with the support surface of the main bracket 10. When the protective side rail 20 is in a vertical state, its second limiting abutting surface abuts against the outer side surface of the corresponding side beam 12, limiting the position of the protective side rail 20 to prevent the protective side rail 20 from further turning toward the main bracket 10, thereby keeping the protective side rail 20 in a vertical state.

[0043] exist Figure 2 In the example shown, the second hinge plate 43 also serves as a limit block. In some other embodiments, a limit block (not shown in the figure) can be separately provided in the hinged flipping mechanism 40, that is, the limit block is independent of the first hinge plate 42 and the second hinge plate 43 which are rotatably connected by the hinge pin 41. The structure of the limit block is similar to that of the second hinge plate 43, which is fixed on the lower cross bar 22 and has two mutually perpendicular limit abutment surfaces, which respectively abut against the outer side surface of the side beam when the protective side rail is in a horizontal state and a vertical state.

[0044] like Figure 1 As shown, the mounting bracket 30 includes a mounting plate 31 and a diagonal beam 32 corresponding to the two main beams, the lower portion of the front side of the mounting plate 31 is fixedly connected to the rear end of the corresponding main beam 11; the diagonal beam 32 is arranged on the upper side of the corresponding main beam 11, the lower end of the diagonal beam 32 is fixedly connected to the upper side of the rear section of the corresponding main beam 11, and the upper end of the diagonal beam 32 is fixedly connected to the upper portion of the front side of the corresponding mounting plate 31. The diagonal beam 32, the mounting plate 31 and the rear portion of the main beam 11 form a triangular structure, thereby ensuring that it has sufficient strength.

[0045] Optionally, the battery holder for battery replacement in this embodiment is mirror-symmetrical about the center plane.

[0046] This embodiment also provides a battery replacement vehicle, which includes the aforementioned battery replacement battery bracket 200. Figure 5 As shown, the frame of the battery swapping vehicle can be an articulated frame, the battery swapping battery bracket 200 is arranged on the front side of the front frame 401 of the articulated frame, the mounting bracket 30 is fixedly connected to the front end of the front frame 401, the rear frame 402 is hingedly connected to the front frame 401, the cab is installed at the front of the rear frame, and the battery swapping working device 300 is installed at the rear of the front frame. The battery swapping vehicle adopts an articulated frame, which is similar to the frame structure of a loader, so that it has strong off-road capabilities and is suitable for battery swapping operations on electric engineering machinery in work sites with uneven ground.

[0047] The working device 300 for battery swapping is installed on the front frame 401 through its rotating mechanism. The working device 300 for battery swapping has a liftable telescopic arm assembly, and is connected to the power battery 100 through the accessories at its front end. The working device 300 for battery swapping can adjust the posture and position of the power battery 100 through its rotating mechanism, the extension and lifting of the telescopic arm assembly and the movement of the accessories, thereby realizing the disassembly and assembly of the power battery 100 on the engineering machinery to be replaced.

[0048] In this embodiment, when the battery-swapping vehicle is replacing the battery of an electric engineering machine in the field, the fully charged power battery 100 is placed on the main bracket 10. Figure 3 As shown, the protective side rails 20 on both sides of the main bracket 10 are in a vertical state, standing on both sides of the power battery 100, to protect the power battery 100 during transportation. At the battery swap location, the protective side rails 20 on both sides of the battery bracket 200 are flipped outward, so that two or more power batteries 10 can be placed on it. When the battery swap vehicle drives to the side of the engineering machinery to be replaced, it can open the support legs 410 at the front end of the front frame 401 to support the ground and increase its stability. At the same time, it also flips open the protective side rails 20 to make it flush with the main bracket 10, increasing its space for placing the power battery 100. The battery swap vehicle removes the depleted power battery 100 from the engineering machinery to be replaced by its battery swap working device 300, and places it on the battery bracket 200 with the protective side rails 20 unfolded, as shown. Figure 4 As shown, the fully charged power battery 100 on the battery bracket 200 is installed on the engineering machinery to be replaced, and the battery replacement operation is completed. During the battery replacement process, the removed low-power power battery 100 and the fully charged power battery 100 to be installed can be kept off the ground, so as to avoid the power battery 100 from being contaminated when performing the battery replacement operation on some special working sites such as muddy ground.
