[0002] The seat hood of an electric forklift can usually be opened and flipped by a certain angle, which is convenient for later use and maintenance and meets the requirement of hoisting and replacing the battery of the electric forklift. At present, most forklift hoods on the market are installed by hinge structures, and there are the following disadvantages:

[0003] 1. Due to the structural characteristics of the forklift itself, in order to ensure that there is no interference during the opening process of the hood, the rotation axis of the hinge needs to be higher than the surface of the hood. Whether an external or internal solution is adopted, it will affect the overall appearance of the vehicle.

[0004] 2. Most of the electrical components such as the electric control of the electric forklift are arranged at the rear side of the battery. When the hood is installed by a hinge structure, it can only be flipped and opened backward, and the opening angle is limited, which is not convenient for daily maintenance and repair.

[0025] In the description of the present invention, it should also be noted that unless otherwise clearly defined and limited, the terms "set", "install", "connected", "connected to" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or a communication connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0026] Please refer to Figures 1-6, in the embodiment of the present invention, a forklift box cover that can be opened bidirectionally includes a box cover 1 and a connecting device connected between the box cover 1 and the box body 2; the connecting device includes a front flip mechanism 3, a side flip mechanism 4, and a transition bracket 5 connected between the two. The transition bracket 5 serves as a transition connecting piece between the front flip mechanism 3 and the side flip mechanism 4. The front flip mechanism 3 is installed on the inner side wall of the box body 2, and the side flip mechanism 4 is installed on the bottom end surface of the box cover 1. The transition bracket 5 includes a transition plate 51 and a card slot 52; the transition plate 51 includes a first side plate 511, a second side plate 512, and a third side plate 513 that are pairwise connected and mutually perpendicular. The right angle formed by the first side plate 511, the second side plate 512, and the third side plate 513 is as close as possible to a right angle of the box body 2 when installed in place to reduce space occupation. Specifically, the first side plate 511 is hinged to the front flip mechanism 3, and the second side plate 512 is slidably connected to the side flip mechanism 4; the side of the third side plate 513 parallel to the sliding direction of the side flip mechanism 4 is snap-fitted with the card slot 52; the card slot 52 is fixedly connected to the bottom surface of the box cover 1. When the box cover needs to be opened from the side, it is necessary to first push the side flip mechanism 4 to unlock it from the card slot 52.

[0027] Wherein, one side edge of the third side plate 513 has a wedge-shaped shoe surface, which cooperates with and clamps the wedge-shaped inclined surface inside the card slot 52 to ensure that the side flip mechanism 4 does not interfere when the box cover is flipped forward.

[0028] Furthermore, the front flip mechanism 3 includes a first side plate 31, an upper parallelogram linkage structure one 32 and a lower parallelogram linkage structure one 33 that are pivotally connected together; the two fulcrums of the lower parallelogram linkage structure one 33 are pivotally connected to the first side plate 31, and the two fulcrums of the upper parallelogram linkage structure one 32 are pivotally connected to the first side plate 511. The front flip mechanism 3 further includes a limit block 34 fixedly connected to the first side plate 31, and the limit block 34 is arranged below the lower parallelogram linkage structure one 33 for limiting its initial position.

[0029] The side flip mechanism 4 includes a second side plate 41, an upper parallelogram linkage structure two 42 and a lower parallelogram linkage structure two 43 that are pivotally connected together; the two fulcrums of the lower parallelogram linkage structure two 43 are slidably connected to the second side plate 512, and the two fulcrums of the upper parallelogram linkage structure two 42 are pivotally connected to the second side plate 41.

[0030] It should be noted that, in order to make the overall structure more concise, the upper parallelogram linkage structure 1 32 can be connected by only three linkages, and the distance between the two pivot points of the upper parallelogram linkage structure 1 32 and the first side plate 511 is fixed, and no fourth linkage is required to strengthen the fixation. Similarly, the lower parallelogram linkage structure 1 33 and the upper parallelogram linkage structure 2 42 are not described again. However, since the lower parallelogram linkage structure 2 43 and the second side plate 512 are slidably connected, the fourth linkage is required between the two supporting points of the lower parallelogram linkage structure 2 43 and the second side plate 512 to ensure that the parallelogram structure is not damaged during the sliding process.

[0031] Specifically, the connection between the lower parallelogram connecting rod structure 43 and the second side plate 512 is as follows: two parallel straight slots 5121 are provided on the second side plate 512, and the length direction of the straight slots 5121 is consistent with the sliding direction of the rollover mechanism 4. The fulcrum of the lower parallelogram connecting rod structure 43 is accommodated in the straight slots 5121, and it slides back and forth in a limited manner therein. When the fulcrum of the lower parallelogram connecting rod structure 43 slides to the other end of the straight slots 5121, it drives the third side plate 513 to slide and completely stagger with the slots 52, and then the box cover 2 is opened to one side.

[0032] Furthermore, the top end of the second side plate 41 is bent toward one side to form an L-shaped plate, and the horizontal section of the top end is fixedly connected to the bottom end surface of the box cover 1 by means of fixing parts such as bolts.

[0033] Furthermore, the present invention also includes a telescopic rod 6, which is configured as a gas spring, one end of which is ball-jointed to the bottom surface of the box cover 1, and the other end of which is ball-jointed to the inner wall of the box body 2. It provides power and travel limit for the front and back flipping and side flipping of the box cover 1.

[0034] During use of the present invention, when the box cover 1 needs to be opened forwardly, the lock of the box cover 1 is directly unlocked, and under the thrust of the gas spring, the box cover 1 is automatically flipped backward and opened, and the gas spring stroke limits the maximum opening angle. At the same time, since the second side plate 41 and the transition bracket 5 are both fixedly connected to the box cover 1, they are consistent with the movement trajectory of the box cover 1, and the upper parallelogram connecting rod structure 42 and the lower parallelogram connecting rod structure 43 maintain the initial compression state and flip backward synchronously with the box cover 1.

[0035] When the box cover 1 needs to be opened laterally, while unlocking the lock of the box cover 1, the box cover 1 needs to be pushed to one side. The second side plate 41, the upper parallelogram link structure two 42, the lower parallelogram link structure two 43 and the card slot 52 move laterally synchronously with the box cover 1. When the fulcrum in the straight slot 5121 moves to the other extreme position of the straight slot 5121, the cooperation between the card slot 52 and the third side plate 53 is disconnected. Under the elongation action of the gas spring, the box cover 1 is opened laterally, realizing the flip opening of the box cover without a rotating shaft. At this time, the transition bracket 5, the upper parallelogram link structure one 32 and the lower parallelogram link structure one 33 are fixed under the action of the limit block 34. When the box cover 1 needs to be closed, just press the box cover 1 and push it horizontally to the other side to the extreme position.

[0036] Although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0037] Therefore, the above description is only a preferred embodiment of the present application and is not used to limit the scope of implementation of the present application; that is, all equivalent transformations made according to the scope of the claims of the present application are within the protection scope of the claims of the present application.
