[0029] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0030] Please refer to Figures 1-5 The utility model discloses a cabin structure of an electric forklift, comprising:

[0031] cabin;

[0032] A driving mechanism 210 for driving the wheel 200 is provided in the middle of the cabin, and battery packs 400 are provided on both sides of the driving mechanism 210. Each battery pack 400 includes at least one battery module 420 for storing electrical energy.

[0033] Specifically, the present application divides a battery pack 400 into two smaller battery packs 400, and respectively arranges the two battery packs 400 on both sides of the drive mechanism 210, so that the two battery packs 400 and the drive mechanism 210 are arranged along the width direction of the cabin 100, making full use of the space on both sides of the drive mechanism 210, shortening the length of the forklift, and improving the flexibility of the forklift.

[0034] Furthermore, a steering wheel 300 is provided on both sides of the driving wheel 200 , and the battery pack 400 is arranged above the steering wheel 300 .

[0035] Specifically, a steering wheel 300 is provided on both sides of the driving wheel 200 , and the battery pack 400 is arranged above the steering wheel 300 so that the weight of the battery pack 400 is directly applied to the steering wheel 300 , thereby increasing the downward force of the steering wheel 300 .

[0036] Furthermore, the steering wheel 300 is mounted on a mounting seat 310, and the mounting seat 310 is mounted on the mounting plate 320. One end of the mounting seat 310 passes through the mounting plate 320 and protrudes from the upper surface of the mounting plate 320.

[0037] One or more connecting seats 330 are provided on the upper surface of the mounting plate 320 , and the upper end height of the connecting seat 330 is higher than the upper end height of the mounting seat 310 ; the battery pack 400 is connected to the connecting seat 330 .

[0038] Specifically, to enhance the connection strength between the mounting base 310 and the mounting plate 320, the upper end of the mounting base 310 is typically passed through the mounting plate 320 from bottom to top, which prevents the battery pack 400 from being directly placed on the mounting plate 320. Therefore, the present application provides two connecting bases 330 on the upper surface of the mounting plate 320, with the connecting bases 330 being higher than the mounting base 310, thereby enabling the battery pack 400 to be placed on the connecting bases 330.

[0039] Furthermore, the two battery packs 400 are symmetrical about the central axis of the driving wheel 200 .

[0040] The two battery packs 400 are symmetrical about the central axis of the drive wheel 200, so that the weight on the left and right sides of the cabin 100 is more evenly distributed, the center of gravity is more centered, and the forklift travels more stably.

[0041] Furthermore, the battery pack 400 further includes a box body 410 , the battery module 420 is disposed in the box body 410 , and the outer wall of the box body 410 is in contact with the inner wall of the cabin.

[0042] Specifically, the outer wall of the box body 410 fits with the inner wall of the cabin, thereby enhancing the connection strength between the battery pack 400 and the cabin 100, making it easier for the battery pack 400 to be installed more stably in the cabin 100, and preventing the battery pack 400 from loosening during the driving of the forklift.

[0043] Furthermore, two mounting racks 430 are provided in the box body 410 along its height direction, and a battery module 420 is mounted on each mounting rack 430 .

[0044] Two mounting racks 430 are arranged in the box body 410 along its height direction, and each mounting rack 430 is provided with a battery module 420, so as to increase the height of the battery pack 400, improve the capacity of a single battery pack 400, and make full use of the space in the height direction of the cabin 100.

[0045] Furthermore, the box body 410 is arranged in a hexahedron, and the box body 410 includes a bottom plate 414, a top plate 413, three first side plates 411 and one second side plate 412, the three first side plates 411 are fixed to the bottom plate 414 and the top plate 413, and the second side plate 412 is bolted to the first side plate 411, the bottom plate 414 and the top plate 413.

[0046] Specifically, the second side plate 412 is connected by bolts, so that the second side plate 412 can be detached, and the internal space of the box body 410 can be opened, making it easier for staff to repair and replace the battery module 420.

[0047] Furthermore, a power interface 440 is provided on the top plate 413 .

[0048] The power interface 440 is disposed on the top plate 413 , ie, the upper end of the box body 410 , so as to be electrically connected to the driving mechanism 210 .

[0049] Furthermore, the two battery packs 400 are connected in series or in parallel.

[0050] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0051] In addition, terms such as "first," "second," and "an" in this utility model are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0052] In this utility model, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0053] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.
