Description

Technical Field

[0001] This utility model relates to the field of engineering machinery technology, and in particular to a battery installation device and engineering machinery. Background Technology

[0002] With the development of electric forklifts, the demand for quick-swap battery technology is increasing. Currently, the commonly used solution involves placing a battery box in the middle of the frame, with rollers at the bottom of the box, and left and right limiting devices for the battery, one of which is a movable limiting device. Opening the movable limiting device allows the battery to move left and right for quick swapping. The drawback of this system is that, since the battery is only limited in the left and right directions, the forward / backward and up / down directions rely solely on the friction between the battery, the limiting devices, and the rollers. Under bumpy road conditions, this friction cannot overcome the battery's inertia, causing displacement. This is especially true when using small-capacity batteries, which are more prone to shifting due to their lighter weight, leading to battery limiting failure and safety risks. Utility Model Content

[0033] like Figures 1 to 4As shown, this utility model provides a battery mounting device, including a battery box 10, a first limiting member 20, two second limiting members 30, and a mounting base 40. The first limiting member 20 is disposed on the bottom wall of the battery box 10, and a first limiting surface 21 is provided on the first limiting member 20, which together with the bottom wall of the battery box 10 forms an insertion port. The two second limiting members 30 are both disposed on the bottom wall of the battery box 10, and are spaced apart from the first limiting member 20 along a first direction. The second direction is spaced apart and perpendicular to the first direction; the mounting base 40 is used to install the battery 100. The mounting base 40 can be placed between two second limiting members 30, and the mounting base 40 can be detachably connected to the two second limiting members 30 on both sides along the second direction; a second limiting surface 421 is provided at one end of the mounting base 40 facing the first limiting member 20. The end of the mounting base 40 facing the first limiting member 20 can be inserted into the socket, and the second limiting surface 421 can abut against the first limiting surface 21.

[0034] When installing the battery 100, first, the battery 100 is fixedly installed on the mounting base 40. Then, the mounting base 40 and the battery 100 on the mounting base 40 are placed between the two second limiting members 30. The mounting base 40 and the battery 100 on the mounting base 40 are pushed towards the side closest to the first limiting member 20 along the first direction, so that the end of the mounting base 40 facing the first limiting member 20 is inserted into the socket, and the second limiting surface 421 abuts against the first limiting surface 21. Finally, the two second limiting members 30 are connected to both sides of the mounting base 40 along the second direction. By setting the first limiting member 20, the movement of the mounting base 40 along the first direction can be limited. Through the cooperation of the first limiting surface 21 and the second limiting surface 421, the movement of the mounting base 40 in a direction perpendicular to both the first and second directions can be limited simultaneously. By setting the second limiting member 30, the movement of the mounting base 40 along the second direction can be limited. This improves the reliability of the battery 100 fixing and makes disassembly and assembly convenient.

[0035] In this embodiment, the first limiting member 20 is connected to the bottom wall of the battery box 10 by a first fastener. Optionally, the first fastener is a bolt, nut, screw, or rivet. In other embodiments, the first limiting member 20 and the bottom wall of the battery box 10 can also be connected by welding.

[0036] Reference Figure 1The second limiting member 30 is L-shaped and includes a first connecting portion 31 and a second connecting portion 32 connected vertically. The first connecting portion 31 is connected to the bottom wall of the battery box 10, and the second connecting portion 32 is detachably connected to the mounting base 40. In this embodiment, the first connecting portion 31 is connected to the bottom wall of the battery box 10 by a second fastener. Optionally, the second fastener is a bolt, nut, screw, or rivet. In other embodiments, the first connecting portion 31 and the bottom wall of the battery box 10 can also be connected by welding. In this embodiment, the second connecting portion 32 is detachably connected to the mounting base 40 by a third fastener. Optionally, the third fastener is a bolt, nut, or screw.

[0037] Reference Figure 3 In this embodiment, the mounting base 40 includes a main body 41 and two limiting connecting parts 43. The main body 41 is used to mount the battery 100, and the two limiting connecting parts 43 are disposed on both sides of the main body 41 along a second direction. The two limiting connecting parts 43 can be detachably connected to the second connecting parts 32 of the two second limiting members 30 in a one-to-one correspondence. Through the above-described structural design of the mounting base 40, materials can be saved.

[0038] In this embodiment, the mounting base 40 includes an insertion portion 42, which is disposed at the end of the main body 41 facing the first limiting member 20. The dimension of the insertion portion 42 along the second direction is smaller than the dimension of the main body 41 along the second direction. The insertion portion 42 can be inserted into the socket. The second limiting surface 421 is disposed on the insertion portion 42. Through the above-described structure of the mounting base 40, materials can be saved and the size of the first limiting member 20 can be reduced.

[0039] In this embodiment, the mounting base 40 includes a handle 44, which is disposed at one end of the main body 41 facing away from the first limiting member 20. The mounting base 40 can be pushed and pulled by the handle 44 to move the mounting base 40 in a direction closer to the first limiting member 20 or away from the first limiting member 20 in a first direction, which is convenient to operate.

[0040] Furthermore, referring to Figure 4 The bottom wall of the battery box 10 is provided with rollers 50, the axis of which is parallel to the second direction. The rollers 50 support the mounting base 40 to move along the first direction, making the movement of the rollers 50 smoother and preventing wear between the mounting base 40 and the battery box 10. Optionally, multiple rollers 50 are arranged in a matrix to further improve the smoothness of the roller movement and better prevent wear between the mounting base 40 and the battery box 10. For example, four rollers 50 are arranged in a 2x2 matrix.

[0041] In this embodiment, refer to Figure 4 and combined Figure 1The bottom wall of the battery box 10 includes two first base plates 11 and two second base plates 12. The two first base plates 11 are spaced apart along a first direction, and the two second base plates 12 are connected between the two first base plates 11 and spaced apart along a second direction. A first limiting member 20 is disposed on one of the first base plates 11, and two second limiting members 30 are disposed on the other first base plate 11. A portion of the plurality of rollers 50 are disposed on one of the second base plates 12, and the other portion are disposed on the other second base plate 12. Through the above-described structural arrangement of the battery box 10, materials can be saved, and the contact area with the mounting base 40 can be reduced, effectively avoiding wear with the mounting base 40.

[0042] This utility model also provides an engineering machine, including a battery 100 and the aforementioned battery mounting device, wherein the battery 100 is disposed on a mounting base 40. By adopting the aforementioned battery mounting device, the reliability of the battery 100 is improved, and the need for quick battery replacement is met.
