Description

Technical Field

[0001] The invention relates to the field of automated mechanical equipment, and in particular to an industrial vehicle which is convenient for storing batteries. Background Art

[0002] Industrial vehicles refer to power-driven motor vehicles used to transport, push, pull, lift, stack or stack various goods. Common industrial vehicles include forklifts, side forklifts, tractors, etc.

[0003] In industrial vehicles, electricity is often used as a driving energy source, so a battery box is placed in the vehicle. During the installation or removal of the battery box, due to the large weight of the battery box, third-party tools are often required to assist.

[0004] In the prior art, there are two main solutions for installing and removing the battery box. Solution 1: Lifting solution. In this solution, the industrial vehicle is provided with a battery cover above the battery box. The operator opens the battery cover, uses a lifting device to hook the battery box, and lifts the battery box from the bottom up to remove the vehicle.

[0005] This technical solution has certain defects. Lifting equipment is required to disassemble and replace the battery. Disassembly and assembly is slow, time-consuming, inefficient, and prone to bumps and damage to the battery and the vehicle body.

[0006] Solution 2: Side-pull solution. In this solution, a notch is set on the side of the vehicle body to move the battery out of the vehicle sideways. This process requires a special transport vehicle with multiple corresponding rollers to accommodate the heavy weight of the battery during the process of moving it out of the vehicle body.

[0007] The side-pull solution also has certain defects. First, a special transport vehicle with a rolling drum is required, which increases the equipment cost of this process. Second, the transport vehicle cannot penetrate deeply into the battery compartment, making the battery box unstable when it is pulled out onto the transport vehicle. Summary of the invention

[0008] The purpose of the present invention is to provide an industrial vehicle that is convenient for storing batteries. The batteries can be easily removed or installed laterally. The disassembly and assembly process only requires ordinary forklift equipment, and no additional transport vehicle is required. The batteries are placed stably without the risk of rollover.

[0009] The above technical purpose of the present invention is achieved through the following technical solutions: an industrial vehicle that is convenient for storing batteries, comprising a gantry and a battery box, the gantry is provided with a storage area for accommodating the battery box, the battery box enters and exits the storage area through a side opening provided on the side of the gantry, the gantry is provided with a battery fixing frame supporting the battery box, the gantry is provided with a depth notch in the horizontal direction at the bottom, and a height notch in the vertical direction; the industrial vehicle also comprises a fork frame connected to the gantry, a wheel body installed at the bottom of the gantry, and a lifting device that drives the fork frame to lift and lower vertically.

[0010] As a preferred embodiment of the present invention, it further comprises a counterweight, and the counterweight is connected to a side of the portal frame away from the fork frame.

[0011] As a preferred embodiment of the present invention, a side door is hinged on the side opening.

[0012] As a preferred embodiment of the present invention, the maximum distance between the deep notch and the side opening is greater than the maximum distance between the battery box and the side opening.

[0013] As a preferred embodiment of the present invention, as a preferred embodiment of the present invention, a pedal assembly and an avoidance structure for driving the pedal assembly to move are provided on the door frame.

[0014] As a preferred embodiment of the present invention, the avoidance structure includes a sliding groove provided on the door frame, and the pedal assembly is connected to a side shifting device that drives the pedal assembly to slide horizontally on the sliding groove.

[0015] As a preferred embodiment of the present invention, the avoidance structure includes a telescopic rod, one end of which is connected to the pedal assembly, and the other end of which is connected to the door frame.

[0016] As a preferred embodiment of the present invention, the avoidance structure includes a hinge column, and one side of the pedal assembly is hinged to the hinge column and can be flipped in the vertical direction.

[0017] In summary, the present invention has the following beneficial effects:

[0018] 1. The battery box can be installed and removed laterally from the side door without the need for lifting equipment.

[0019] 2. During the installation and disassembly process, only a vehicle with a fork is required, and there is no need to equip special handling equipment with multiple rollers.

[0020] 3. There are depth gaps and height gaps, and the fork body can carry the battery box without interference throughout the process.

[0021] 4. The pedal assembly has an avoidance structure, which maintains structural integrity in normal conditions and provides the operating space required by the fork body when accessing the battery box.

[0022] 5. When storing and retrieving the battery box, the battery box is located in the middle of the fork body, which is highly balanced. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0030] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.

[0031] Embodiment 1, as Figure 1 and Figure 2 As shown, the front end of the gantry 11 is connected to a fork 16, which can be raised and lowered in the vertical direction to transport goods. A storage area 13 is provided inside the gantry 11, and the battery box 5 is stored in the storage area 13. A side door 14 is provided on the side of the gantry 11. After the side door 14 is opened, the operator can operate the loading or unloading of the battery box 5. A counterweight 12 is provided at the rear end of the gantry 11 to balance the vehicle body. A wheel body 19 is provided at the bottom of the gantry 11.

[0032] like Figure 2 and Figure 3 As shown, the door frame 11 is also provided with a battery fixing frame 15, and the battery box 5 is placed on the battery fixing frame 15 after entering the accommodation area 13. The battery fixing frame 15 is also covered with a buffer pad 151 as a buffer. As the main innovation of this technical solution, Figure 3 As shown, there is a deep notch 17, which can be specifically located in the middle of the battery fixing frame 15, and the extending direction is relative to the left and right side ends of the door frame 11. The function of the deep notch 17 is to provide space for other forks to come in. In the process of installing or removing the battery box 5, it is no longer necessary to use a transporter with rollers in the prior art, but an ordinary forklift can be used to operate directly. The forklift approaches the vehicle, and the operating fork comes in from the deep notch 17 at the bottom. At this time, the front and rear sides of the battery box 5 are against the battery fixing frames 15 at the front and rear ends, and the middle position is located above the fork.

[0033] Then, the fork rises, as Figure 2 As shown, a vertical avoidance space, i.e., a height notch 18, is specially provided on the door frame 11. The fork body rises with the battery box 5, passes through the height notch 18, and then moves the battery box 5 out from the side door 14. The same is true when installing the battery box 5.

[0034] In this case, the maximum distance between the deep notch 17 and the side opening is greater than the maximum distance between the battery box 5 and the side opening. Under such a structural design, the fork body can be extended further, so that the battery box 5 is pressed on the middle part of the fork body instead of the end, and the balance of the battery box 5 can be better.

[0035] A pedal assembly 2 is also provided on the door frame 11. The pedal assembly 2 includes a pedal plate body 21. The pedal plate body 21 is provided with a pedal switch. When the user does not step on the pedal switch, the vehicle does not move. Only when the user steps on the pedal switch can the vehicle be operated to move, thereby improving safety.

[0036] In this case, in a normal state, the pedal plate 21 fills the deep notch 17 to maintain the integrity of the entire structure. When the battery box 5 needs to be operated, the pedal assembly 2 needs to avoid the fork body under the drive of the avoidance structure, so that the pedal assembly 2 and the fork body do not interfere.

[0037] In this implementation, if Figure 4 As shown, a connecting frame 22 is provided on the pedal plate body 21, and a connecting shaft 23 is provided in the door frame 11. One end of the connecting frame 22 is fixedly connected to the pedal plate body 21, and the other end includes a rotating part 221, which is sleeved on the connecting shaft 23. A buffer pop-up member 3 is provided, and the buffer pop-up member 3 may include a spring, and one end thereof contacts the rotating part 221. When the user leaves the pedal plate body 21, the rotating part 221 rotates under the influence of the spring force, driving the entire connecting frame 22 and the pedal plate body 21 to bounce upward at a slightly smaller angle. Subsequently, the user can manually lift the pedal plate body 21 to start the lifting member 4 to work. The lifting member 4 may specifically be a hydraulic rod, which is also connected to the connecting frame 22 to pull the entire pedal plate body 21 upward to complete the avoidance action.

[0038] Embodiment 2 is different from Embodiment 1 in the specific implementation of the avoidance structure of the pedal assembly 2. In this embodiment, multiple hydraulic rods can be arranged to extend and retract in the vertical direction and connected to the pedal plate body 21, so that the pedal plate body 21 can be raised and lowered vertically to avoid the fork body.

[0039] Embodiment 3 is different from Embodiment 1 in the specific implementation of the avoidance structure of the pedal assembly 2. In this embodiment, a corresponding sliding groove may be provided in the door frame 11, and a corresponding sliding member may be connected to the pedal plate body 21. A power component such as a hydraulic rod that can be extended in the horizontal direction may also be provided, and the pedal plate body 21 slides away horizontally to complete the avoidance.
