Description

Technical Field

[0001] This utility model relates to the field of electric forklift charging technology, and in particular to a fast charging device for electric forklifts. Background Technology

[0002] In the modern logistics industry, electric forklifts are widely used due to their environmental friendliness and low noise. With increasing demands for logistics efficiency, the charging efficiency and convenience of electric forklifts have become crucial factors. However, existing electric forklift charging devices present many inconveniences in practical use. For example, traditional devices typically require manual operation of the protective cover on the charging gun's front connector. Frequent manual opening and closing is time-consuming and laborious, especially in scenarios requiring frequent charging, reducing charging efficiency, and the protective cover is easily lost.

[0003] Furthermore, existing devices often lack a stable and flexible placement design for the charging gun. The charging gun can be placed haphazardly without a dedicated fixing structure, potentially causing it to shake or fall during charging, posing a risk of equipment damage and safety hazards. Simultaneously, existing devices typically cannot adjust the placement height of the charging gun according to the operator's height, which may be inconvenient for operators of different heights when retrieving and placing the charging gun, and can lead to fatigue during prolonged operation. These problems collectively result in deficiencies in the operational convenience, efficiency, and safety of existing electric forklift charging devices. Therefore, improvements to the existing technology are urgently needed to address these issues. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fast charging device for electric forklifts.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a fast charging device for electric forklifts, including a bracket with a vertical support rod.

[0006] The device also includes a charging gun with a protective component. The protective component includes a housing fixed to the outer shell of the charging gun, a dual-axis motor inside the housing, a worm gear driven by both ends of the dual-axis motor, a worm wheel driven by the worm gear, a vertical shaft driven by the worm wheel, a horizontal connecting rod connected by the vertical shaft, and a protective cover at the end of the horizontal connecting rod. The two protective covers are rotatably mounted on the front connector of the charging gun to protect the front connector.

[0007] The device also includes a lifting component mounted on the vertical support rod. The lifting component includes a support rod arranged vertically along the vertical support rod and a locking screw for fixing the position of the support rod. The support rod is provided with a fixing block for placing the bottom of the charging gun and two insert rods that cooperate with the fixing block. The support rod is also provided with a limiting hole that cooperates with the insert rods.

[0008] Furthermore, the charging gun is equipped with a switch for controlling the rotation of the dual-axis motor.

[0009] More specifically, the switch controls the dual-axis motor to rotate forward or backward via an electrical connection, thereby driving the protective cover to rotate open or close.

[0010] Preferably, the output shaft of the dual-axis motor is connected to the worm, the worm meshes with the worm wheel for transmission, the central shaft of the worm wheel is connected to the vertical shaft, the lower end of the vertical shaft rotates through the housing and extends downward, and the horizontal connecting rod is fixedly connected to the lower end surface of the vertical shaft.

[0011] Furthermore, the locking screw is threaded through the support rod, and the end of the locking screw abuts against the wall of the vertical support rod to fix the position of the support rod along the vertical support rod.

[0012] Preferably, the support is a frame structure.

[0013] Furthermore, the charging gun is equipped with a handle.

[0014] Preferably, the dual-axis motor is a miniature dual-axis motor.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] By incorporating a protective component on the charging gun, driven by a dual-axis motor and worm gear transmission mechanism, the protective cover of this component can automatically open and close, thus achieving automatic protection of the charging gun's front connector. This solves the problems of time-consuming, laborious, and easily lost manual operation of the protective cover in existing technologies, significantly improving the efficiency and convenience of charging operations. Simultaneously, the device features a height-adjustable support rod on the vertical support frame, which can be fixed with locking screws. This support rod has a placement structure consisting of a fixing block, a plug, and a limiting hole that mates with the bottom of the charging gun. This structure stably supports and positions the charging gun, solving the problems of unstable placement and easy shaking and falling in existing technologies, thus improving safety. Furthermore, the height adjustment function of the support rod along the vertical support frame allows operators to adjust the placement height of the charging gun according to their own height and habits, solving the problems of inconvenience and fatigue caused by fixed height in existing technologies, and improving user comfort. Therefore, through the above-mentioned structural design, this utility model effectively solves the shortcomings of existing electric forklift charging devices in terms of ease of operation, efficiency, safety and comfort, and has significant technological progress and practical value.

[0022] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0023] Against the backdrop of the rapid development of the modern logistics industry, electric forklifts are widely used due to their environmental friendliness and low noise characteristics. However, existing electric forklift charging devices have many inconveniences in actual operation. For example, the protective cover of the charging gun's front connector usually needs to be manually opened and closed, which is time-consuming and laborious in scenarios with frequent charging, and the protective cover is also easy to lose. In addition, existing devices lack a stable and flexible design for placing the charging gun, which can easily be placed haphazardly, potentially causing it to shake or fall, posing a safety hazard. Furthermore, the placement height is usually not adjustable according to the operator's height, affecting the user experience. To overcome these shortcomings of the existing technology, this utility model proposes a fast charging device for electric forklifts. This device, by incorporating automated protective components and adjustable lifting components, significantly improves the convenience, efficiency, safety, and comfort of charging operations.

[0024] like Figures 1 to 4 The fast charging device for an electric forklift shown includes a bracket 1, on which a vertical support rod 101 is provided, and further includes:

[0025] The charging gun 3 is equipped with a protective component 6. The protective component 6 includes a housing 601 fixed on the outer shell of the charging gun 3, a dual-axis motor 606 disposed inside the housing 601, a worm gear 605 connected to both ends of the dual-axis motor 606, a worm wheel 603 connected to the worm gear 605, a vertical shaft 604 connected to the worm wheel 603, a horizontal connecting rod 607 connected to the vertical shaft 604, and a protective cover 602 disposed at the end of the horizontal connecting rod 607. The two protective covers 602 are rotatably covered on the front end socket of the charging gun 3 to protect the front end socket.

[0026] The lifting component 7 is mounted on the vertical support rod 101. The lifting component 7 includes a support rod 701 vertically arranged along the vertical support rod 101 and a locking screw 703 for fixing the position of the support rod 701. The support rod 701 is provided with a fixing block 9 for placing the bottom of the charging gun 3 and two insert rods 10 that cooperate with the fixing block 9. The support rod 701 is also provided with a limiting hole 702 that cooperates with the insert rods 10.

[0027] When using the fast charging device for electric forklifts of this invention, firstly, the operator can, according to their height and operating habits, loosen the locking screw 703 on the lifting component 7, and then move the support rod 701 up or down to raise or lower it along the vertical frame rod 101. After adjusting the height of the support rod 701 to a suitable position, tighten the locking screw 703 to make it abut against the wall of the vertical frame rod 101, thereby fixing the position of the support rod 701. Next, place the charging gun 3 on the support rod 701, so that the fixing block 9 at the bottom of the charging gun 3 is placed on the top of the support rod 701, and at the same time, insert the two insertion rods 10 on the charging gun 3 into the corresponding limiting holes 702 on the support rod 701, thereby achieving stable placement of the charging gun 3. When it is necessary to charge the electric forklift, the operator can use the switch 5 on the charging gun 3 (see...) Figure 1 and Figure 2 The dual-axis motor 606 in the protection component 6 is activated. The dual-axis motor 606 rotates, driving the worm gear 605 to rotate the worm wheel 603. The worm wheel 603 drives the vertical shaft 604 to rotate, which in turn drives the horizontal connecting rod 607, causing the protective cover 602 to rotate and open, thus removing the protective barrier around the front connector of the charging gun 3. Then, the operator holds the handle 4 of the charging gun 3 (see...). Figure 1 and Figure 2The charging gun 3's front connector is inserted into the forklift's charging interface. The charging pile 8 provides power to the charging gun 3 via the charging cable 2, charging the electric forklift. After charging, the dual-axis motor 606 is reversed via switch 5, causing the two protective covers 602 to close, further protecting the front connector of the charging gun 3. During this process, the protective component 6, through a transmission mechanism consisting of the dual-axis motor 606, worm gear 605, worm wheel 603, vertical shaft 604, and horizontal connecting rod 607, automatically opens and closes the protective covers 602, eliminating the hassle of manual operation. The lifting component 7, through the cooperation of the support rod 701, locking screw 703, fixing block 9, insertion rod 10, and limiting hole 702, provides a stable, height-adjustable placement platform for the charging gun 3, ensuring its safety and order when not in use.

[0028] As one embodiment of this utility model, the charging gun 3 is equipped with a switch 5, which is used to control the rotation of the dual-axis motor 606.

[0029] In practice, a switch 5 is installed on the charging gun 3. This switch 5 is electrically connected to the dual-axis motor 606 within the protective component 6. The function of the switch 5 is to provide the operator with a convenient control interface for starting or stopping the rotation of the dual-axis motor 606. Through this switch 5, the operator can easily control the opening and closing of the protective cover 602 while holding the charging gun 3.

[0030] In one embodiment of this utility model, the switch 5 controls the dual-axis motor 606 to rotate in the forward or reverse direction via electrical connection, so as to drive the protective cover 602 to rotate open or close.

[0031] In practice, when the protective cover 602 needs to be opened, the dual-axis motor 606 is controlled to rotate in the forward direction by switch 5; when the protective cover 602 needs to be closed, the dual-axis motor 606 is controlled to rotate in the reverse direction by switch 5.

[0032] In one embodiment of this utility model, the output shaft of the dual-axis motor 606 is connected to the worm 605, the worm 605 meshes with the worm wheel 603 for transmission, the central shaft of the worm wheel 603 is connected to the vertical shaft 604, the lower end of the vertical shaft 604 rotates through the housing 601 and extends downward, and the horizontal connecting rod 607 is fixedly connected to the lower end surface of the vertical shaft 604.

[0033] In one embodiment of this utility model, the locking screw 703 is threaded through the support rod 701, and the end of the locking screw 703 abuts against the wall of the vertical support rod 101 to fix the position of the support rod 701 along the vertical support rod 101.

[0034] Specifically, the locking screw 703 is threaded through a threaded hole on the support rod 701. When it is necessary to fix the position of the support rod 701 on the vertical support rod 101, tightening the locking screw 703 causes its end to move inward and press against the outer surface (i.e., the rod wall) of the vertical support rod 101. The friction between the locking screw 703 and the rod wall of the vertical support rod 101, as well as possible slight deformation, effectively prevents the support rod 701 from sliding vertically along the vertical support rod 101, thereby fixing the support rod 701 at the desired height. When it is necessary to adjust the height of the support rod 701, simply loosen the locking screw 703 to separate its end from the rod wall of the vertical support rod 101, and the support rod 701 can be moved freely.

[0035] As one embodiment of this utility model, the bracket 1 is a frame structure.

[0036] In one embodiment of this utility model, the charging gun 3 is provided with a handle 4; the handle 4 is designed in a shape and size that is easy for the operator to grip. Its main function is to provide a stable grip point, making it easier and less strenuous for the operator to pick up and put down the charging gun 3, insert it into the charging interface of the electric forklift, or pull it out of the interface.

[0037] As one embodiment of this utility model, the dual-axis motor 606 is a miniature dual-axis motor.

[0038] Working principle of this utility model:

[0039] The entire device is supported on the ground by bracket 1. Two protective covers 602 are placed over the front connector of the charging gun 3 to protect it. A housing 601 is fixed to the outer shell of the charging gun 3, protecting the worm gear 603, worm 605, and dual-axis motor 606 inside. When charging an electric forklift with the charging gun 3, the dual-axis motor 606 in the protective component 6 is activated by switch 5 on the charging gun 3. The dual-axis motor 606 then drives the two worm gears 603, worm 605, and dual-axis motor 606. 5. When the worm gear 605 rotates, it drives the worm wheel 603 to rotate, and the worm wheel 603 drives the vertical shaft 604 to rotate. The two vertical shafts 604 rotate the protective cover 602 with the help of the horizontal connecting rod 607 on the surface, so that the two protective covers 602 rotate and open. Then the two protective covers 602 no longer protect the front plug of the charging gun 3. The method of using the dual-axis motor 606 to drive the two protective covers 602 to rotate and open is faster and more convenient than the traditional method of manually opening the cover on the front plug of the charging gun 3.

[0040] Then, the operator inserts the front connector of the charging gun 3 into the forklift charging interface by holding the handle 4. The charging pile 8 provides power to the charging gun 3 through the charging cable 2 to charge the electric forklift. After charging is completed, the dual-axis motor 606 is rotated in reverse by the switch 5, so that the two protective covers 602 cover the front connector of the charging gun 3 again. Then, the two rods 10 at the bottom of the fixing block 9 at the bottom of the charging gun 3 are inserted into the corresponding limiting holes 702, so that the fixing block 9 is placed on the top of the support rod 701, thereby achieving stable placement of the charging gun 3. According to the operator's usual operating height for picking up and putting down the charging gun 3, the locking screw 703 in the lifting component 7 is loosened, and then the support rod 701 is moved up or down to rise and fall along the vertical frame rod 101. The height of the support rod 701 is adjusted to meet the operator's use height requirements and then stopped. Then the locking screw 703 is tightened to make it abut against the wall of the vertical frame rod 101, thereby fixing the position of the support rod 701.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model.
