[0030] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present application.

[0031] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the scope of this application and its application or use.

[0032] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0033] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0034] This application provides a waterproof device for an electric forklift controller. A waterproof plate is rotatably connected to the vehicle body. When maintaining the controller, the waterproof plate is first slid relative to the battery box cover to make room, and then the waterproof plate is rotated to remove the waterproof plate from covering the controller. The controller can be maintained without removing the waterproof plate, which significantly improves the maintenance efficiency of the controller.

[0035] The waterproof device for the electric forklift controller provided in this application is installed between the controller and the battery box cover, ensuring that water seepage from the battery box cover gaps and water accumulation when the battery box cover is opened will not drip onto the controller surface, but will instead be diverted to both sides of the vehicle body through the waterproof membrane. Figure 1 As shown, the waterproofing device includes a waterproof membrane 1, two mounting bracket assemblies 2 and 3 symmetrically arranged relative to and rotatably connected to the waterproof membrane 1, and a guide rail block disposed between the waterproof membrane 1 and the mounting bracket assemblies. Figure 1 As shown, a first guide rail block 4 is provided between the waterproof plate 1 and the mounting bracket assembly 2 on the left, and a second guide rail block 5 is provided between the waterproof plate 1 and the mounting bracket assembly 3 on the right. The mounting bracket assembly 2 on the left and the mounting bracket assembly 3 on the right are symmetrical in structure, and the first guide rail block 4 and the second guide rail block 5 are also symmetrical in structure.

[0036] like Figure 2As shown, the waterproof membrane 1 includes a main body 11 and two connecting ears 12 symmetrically fixed on the same side of the main body 11. The connecting ears 12 are L-shaped, and one end of the right-angled side of the connecting ear 12 is fixedly connected to the main body.

[0037] As an example, the waterproof membrane 1 is an injection-molded part made of modified PP material, which has sufficient strength and toughness.

[0038] The following explanation uses the mounting bracket assembly 2 on the left and the first guide rail block 4 as an example. Figure 1 As shown, the first end of the mounting bracket assembly 2 is fixedly connected to the vehicle body, and the second end of the mounting bracket assembly is rotatably connected to the guide rail block 4.

[0039] Specifically, such as Figure 3 As shown, the mounting bracket assembly 2 includes a mounting plate 21 and a sleeve 22. The first end of the mounting plate 21 is fixedly connected to the vehicle body, and the sleeve 22 is fixed on the top surface of the second end of the mounting plate 21. The axis of the sleeve 22 is parallel to the length direction of the waterproof membrane 1.

[0040] like Figure 3 As shown, the mounting plate 21 is a Z-shaped bent sheet metal part. The first end of the mounting plate 21 is parallel to the second end, and a vertical plate is provided between the first end and the second end. The first end of the mounting plate 21 is provided with two U-shaped slots 211. After the bolts pass through the U-shaped slots 211 and the mounting holes on the vehicle body, the mounting plate 21 is fixed to the vehicle body.

[0041] like Figure 4 As shown, the guide rail block 4 has a guide groove 41 on the side facing the connecting ear 12, and the other end (i.e., the other right-angled side) of the connecting ear 12 is slidably disposed in the guide groove 41. The guide rail block 4 has a through hole 42 coaxial with the sleeve 22. Please refer to... Figure 1 and 4 The guide slot 41 is located between the through hole 42 and the main body 11 of the waterproof plate 1. The cylindrical pin 7 passes through the through hole 42 and the sleeve 22, and passes through the through hole 71 at the tail of the cylindrical pin 7 (see...). Figure 8 The locking element inside limits the rotation of the connecting guide block 4 and the mounting plate 21.

[0042] Preferably, the two opposite sidewalls of the guide slot 41 ( Figure 4 The upper and lower side walls (shown in the middle) are provided with coaxial positioning holes 45 and 46, which are connected to the guide groove 41 near the main body 11. Figure 4 The distance between the two sides (shown as the left side of the groove) is the same as the width of the other right-angled side of the connecting ear 12. Therefore, when maintenance is not required, the other right-angled side of the connecting ear 12 inserts into the guide slot 41 and abuts against the groove wall near the main body 11, with limiting pins 6 (see [reference]) respectively inserted into the positioning holes 45 and 46. Figure 1This allows for limiting the movement of the connecting ear 12 on both sides, preventing the waterproof plate from shaking during forklift operation.

[0043] As an example, guide block 4 is an injection molded part.

[0044] like Figure 7 As shown, the limiting pin 6 includes a limiting post 62 and a pull ring 61 disposed at one end of the limiting post 62. When maintenance is required, the limiting pin 6 can be pulled off using the pull ring 61, allowing the connecting lug 12 to slide relative to the guide rail block 4.

[0045] Preferably, the mounting bracket assembly 2 further includes a limiting block 23, which is fixed to the mounting plate 21. The limiting block 23 and the main body 11 are located on both sides of the sleeve 22. Thus, when the controller needs to be maintained, the waterproof plate 1 and the guide rail block 4 are rotated together relative to the mounting plate so that they abut against the limiting block 23, thereby achieving limiting and support.

[0046] As an example, the limiting block 23 is a sheet metal part.

[0047] Based on the above, preferably, such as Figure 4 As shown, a right-angled notch 43 is provided at one corner of the guide rail block 4 to accommodate the sleeve 22 and the limiting block 23. The second end of the mounting plate 21 is attached to the lower part of the guide rail block 4, so that the sleeve 22 and the limiting block 23 are accommodated in the right-angled notch 43, which improves the compactness of the structure.

[0048] Based on the above, preferably, such as Figure 4 As shown, the first inclined plane 44 is located at one outer edge of the right-angled notch 43. Figure 3 As shown, the end of the limiting block 23 that is away from the mounting plate 21 ( Figure 3 The side of the upper end (shown in the middle) near the sleeve 22 is the second inclined surface 231. After rotating the waterproof plate 1 and the guide block 4, when the guide block 4 is perpendicular to the second end of the mounting plate 21, the first inclined surface 44 and the second inclined surface 231 are in contact, thereby increasing the stability of the waterproof plate at this time.

[0049] When maintaining the controller, first slide the waterproof plate relative to the battery box cover, causing the waterproof plate to move towards the sleeve, thus making way for the battery box cover. Figure 5 As shown. Then, using the hinge between the cylindrical pin and the sleeve, the waterproof plate and guide block are rotated, causing the waterproof plate to release its cover over the controller. The controller is then locked in the open state by the structure's own weight and the limit block, as shown. Figure 6 As shown, this allows for controller maintenance without removing the waterproof membrane. After controller maintenance is complete, rotate the waterproof membrane and guide rail block to allow them to fall onto the mounting plate. Move the waterproof membrane away from the sleeve and insert the limit pins at both ends to lock it in the closed state. This enables the waterproof device to open and close quickly, greatly reducing controller maintenance time.

[0050] While specific embodiments of this application have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of this application. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of this application. The scope of this application is defined by the appended claims.
