Description

Technical Field

[0001] This utility model relates to the field of forklifts, specifically to a quick-release tilt stop device for a forklift battery and a forklift. Background Technology

[0002] Forklifts are among the most commonly used material handling vehicles and are essential equipment in the logistics industry. They are wheeled handling vehicles used for loading, unloading, stacking, and short-distance transport of palletized goods, as well as for handling heavy objects. Currently, electric forklift technology is mature. To enable continuous operation, the forklift battery is typically removable and installed in the battery compartment of the forklift frame. When the battery is depleted, it can be replaced to continue operation.

[0003] Existing forklift batteries are stopped by limit brackets locked to the frame, such as by bolts. Each time the battery is replaced, tools such as wrenches are needed to remove the bolts first, then remove the limit bracket to replace the battery. After the replacement is completed, the limit bracket needs to be locked back to the frame. The operation is cumbersome and inefficient. Moreover, the removed parts (limit brackets and bolts, etc.) are easy to lose. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a quick-release tilt stop device for a forklift battery and a forklift.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] A quick-release tilt stop device for a forklift battery, wherein the forklift battery is installed in the battery compartment of the vehicle frame, includes a stop frame, a first fixing member, and a second fixing member. The stop frame is provided with a first elongated slot and a second elongated slot extending in a first direction, and a clearance window that is laterally connected to a portion of the second elongated slot. The first fixing member and the second fixing member pass through the first elongated slot and the second elongated slot respectively and are fixed to the vehicle frame so that the stop frame is in a stop state that extends into the battery compartment. The reciprocating movement of the stop frame in the first direction causes the second fixing member to switch between a first position offset from the clearance window and a second position corresponding to the clearance window. When the second fixing member corresponds to the clearance window, the stop frame can swing outward with the first fixing member as a fulcrum to disengage the stop frame from the battery compartment.

[0007] Furthermore, the frame is also equipped with a vertically flip-up compartment door, and the stop bracket can swing outward to protrude from the outside of the frame, thereby preventing the compartment door from closing.

[0008] Furthermore, the frame is provided with a first limiting hole, and the stop bracket is equipped with a pin. When the stop bracket is in the first position, the pin corresponds to the first limiting hole and is inserted into the first limiting hole to achieve locking.

[0009] Furthermore, the frame is also provided with a second limiting hole. When the stop bracket swings outward to a position protruding from the outside of the frame, the pin is inserted into the second limiting hole to achieve locking.

[0010] Furthermore, the pin component includes a fixed base, a tension spring, and a pin. The fixed base has a guide hole and is fixed on the stop bracket. The pin is inserted into the guide hole of the fixed base, and the tension spring is connected between the fixed base and the pin.

[0011] Furthermore, the clearance window is laterally connected to one end of the second elongated slot.

[0012] Furthermore, the stop frame has a Z-shaped cross-section, including a fixed plate, a stop plate, and a connecting plate connecting the fixed plate and the stop plate. The first elongated slot and the second elongated slot are formed on the fixed plate, and the clearance window is formed on the fixed plate and extends through to the connecting plate. The stop plate is used to extend into the battery compartment to stop the battery inside the battery compartment.

[0013] Furthermore, both the first and second fixing components are bolts.

[0014] A forklift includes a frame with a battery compartment containing a forklift battery; wherein the frame is provided with a quick-release tilt stop device for the forklift battery as described above.

[0015] Furthermore, a quick-release tilt stop device for the forklift battery is provided on at least one opposite side of the battery compartment.

[0016] The technical solution provided by this utility model has the following beneficial effects:

[0017] Under normal forklift operation, the second fixing member is in a first position offset from the clearance window; the stop bracket is restrained by both the first and second fixing members and is in a stop state, limiting the forklift battery and ensuring stable battery installation. When battery replacement is required, push the stop bracket to move in the first direction, aligning the second fixing member with the clearance window. At this time, the stop bracket can swing outward with the first fixing member as a fulcrum to disengage from the battery compartment, completing the clearance, allowing normal battery replacement. After replacement, swing the stop bracket inward until the second fixing member re-engages with the second elongated slot, then push the stop bracket in the opposite direction to place the second fixing member in the first position offset from the clearance window, completing the entire replacement process. The overall operation is simple, saving time and improving efficiency; no parts need to be removed. Attached Figure Description

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0027] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0028] Reference Figures 1 to 7 As shown in the figure, this embodiment provides a quick-release tilt stop device for a forklift battery. The forklift battery 3 is installed in the battery compartment 2 of the frame 1. Specifically, the quick-release tilt stop device for the forklift battery includes a stop frame 10, a first fixing member 21, and a second fixing member 22. The stop frame 10 is provided with a first elongated slot 101 and a second elongated slot 102 extending along a first direction (such as the front-to-back extension direction), and a clearance window 103 that laterally connects to a portion of the second elongated slot 102. Specifically, the first elongated slot 101 and the second elongated slot 102 are on the same axis; the portion of the second elongated slot 102 refers to a part of the second elongated slot 102; the extension direction of the clearance window 103 is perpendicular to the first direction. Of course, the first elongated slot 101 and the second elongated slot 102 may not be on the same axis, as long as they extend in the same direction (i.e., the first direction).

[0029] The first fixing member 21 and the second fixing member 22 pass through the first elongated slot 101 and the second elongated slot 102 respectively and are fixed to the vehicle frame 1. That is, the first fixing member 21 passes through the first elongated slot 101 and is fixed to the vehicle frame 1, and the second fixing member 22 passes through the second elongated slot 102 and is fixed to the vehicle frame 1, so that the stop bracket 10 is in a stop state extending into the battery compartment 2. The reciprocating movement of the stop bracket 10 in the first direction causes the second fixing member 22 to be in a first position offset from the clearance window 103 (e.g., Figure 3 (as shown) and the second position corresponding to the yielding window 103 (as shown) Figure 4 Switching between (as shown), specifically, when the stop bracket 10 moves back and forth in the first direction, the first fixing member 21 and the first elongated slot 101 also move relative to each other. And when the second fixing member 22 corresponds to the clearance window 103, the stop bracket 10 can swing outwards with the first fixing member 21 as a fulcrum to disengage the stop bracket 10 from the battery compartment 2, i.e., from... Figure 4 The status shown has switched to Figure 6 The state shown.

[0030] The stop bracket 10 can be switched between three positions, namely, the first position in which the second fixing member 22 is in the second elongated slot 102 and offset from the clearance window 103 (e.g., Figure 3 As shown), the second fastener 22 is located within the second elongated slot 102 and in the second position corresponding to the clearance window 103 (as shown). Figure 4 (as shown) and the stop bracket 10 swings outward with the first fixing member 21 as the fulcrum so that the stop bracket 10 disengages from the third position of the battery compartment 2 (as shown). Figure 6 (As shown). In both the first and second positions, the stop bracket 10 is in a stop state that extends into the battery compartment 2.

[0031] Under normal operating conditions of the forklift, such as Figure 3 As shown, the second fixing member 22 is in a first position that is offset from the clearance window 103; at this time, the stop bracket 10 cannot swing outward and remains in the stop state that extends into the battery compartment 2, which effectively stops the forklift battery 3 in the battery compartment 2 and ensures the stable installation of the forklift battery 3.

[0032] When the battery needs to be replaced, push the stop 10 to move in the first direction (e.g., forward) so that the second fixing member 22 corresponds to the clearance window 103, reaching the desired position. Figure 4 In the state shown, at this time, rotate the stop bracket 10 again, so that the stop bracket 10 swings outward with the first fixing member 21 as the fulcrum and disengages from the battery compartment 2, completing the repositioning, as shown. Figure 6 As shown, the forklift battery 3 can be replaced normally at this time; after the replacement is completed, swing the stop bracket 10 inward until the second fixing member 22 re-engages with the second elongated slot 102, that is, from Figure 6 The status shown has switched to Figure 4 As shown in the diagram, the stop 10 is then pushed in the reverse (backward) direction, causing the second fixing member 22 to switch to a first position offset from the clearance window 103, i.e., from... Figure 4 The status shown has switched to Figure 3 The entire replacement process is complete as shown in the diagram. The overall operation is simple, saving time and improving efficiency; no parts need to be removed.

[0033] The frame 1 is also equipped with a vertically tiltable cargo door 4. The stop bracket 10 can swing outward to protrude beyond the outer side of the frame 1, thereby preventing the cargo door 4 from closing. That is, when the stop bracket 10 is in the third position, it protrudes beyond the outer side of the frame 1. With this configuration, if the stop bracket 10 is not reset, i.e., when the stop bracket 10 is still in the third position, the cargo door 4 cannot be closed. Only when the stop bracket 10 switches to the stop position will it not obstruct the closing of the cargo door 4. This provides a clear reminder to the operator that the forklift battery 3 has not been stopped, effectively preventing mistaken opening.

[0034] The frame 1 is also provided with a first limiting hole 5, and the stop frame 10 is equipped with a pin 23. When the stop frame 10 is in the first position, the pin 23 corresponds to the first limiting hole 5 and is inserted into the first limiting hole 5 to achieve locking, so as to prevent the stop frame 10 from disengaging from the stop state due to misoperation or the bumps of the forklift.

[0035] More specifically, to prevent the stop bracket 10 from disengaging from the third position due to accidental contact by the operator and subsequent forgetting to reset it, in this embodiment, the frame 1 is also provided with a second limiting hole 6. When the stop bracket 10 swings outward to a position protruding beyond the outer side of the frame 1 (i.e., the third position), the pin 23 corresponds to the second limiting hole 6 and is inserted into it to achieve locking. Similarly, this design can lock the stop bracket 10 in the third position, requiring the operator to pull out the pin 23 before it can be cut out from the third position, thus providing a better foolproof effect.

[0036] Specifically, in this embodiment, the pin 23 includes a fixed base, a tension spring, and a pin. The fixed base has a guide hole and is fixed to the stop bracket 10. The pin is inserted into the guide hole of the fixed base, and the tension spring connects the fixed base and the pin. When the pin is inserted into the first limiting hole 5 or the second limiting hole 6, the tension spring applies a pulling force to keep the pin in place. When it needs to be pulled out, the pin is lifted, causing it to disengage from the currently engaged first limiting hole 5 or second limiting hole 6. When switching to the next holding position (e.g., from the first position to the third position), the pin is released, and the pin automatically resets under the action of the tension spring and is inserted into the corresponding limiting hole, simplifying the operation and eliminating the need to remove the pin 23 separately. Of course, in other embodiments, the structure of the pin 23 is not limited to this.

[0037] Specifically, the clearance window 103 is laterally connected to one end (such as the first end) of the second elongated slot 102. That is, when the stop bracket 10 is moved along the first direction so that the second fixing member 22 engages with the first end of the second elongated slot 102, the clearance window 103 is in the second position. At this time, the stop bracket 10 can be rotated. When the second fixing member 22 engages with the second end of the second elongated slot 102, it is in the first position, and the stop bracket 10 cannot be rotated. During operation, simply push the stop bracket 10 back and forth along the first direction until it can no longer move to complete the switch between the first position and the second position, which is more convenient for operation. Of course, in other embodiments, the clearance window 103 can also be laterally connected to the middle position of the second elongated slot 102.

[0038] The stop bracket 10 has a Z-shaped cross-section and includes a fixed plate 11, a stop plate 12, and a connecting plate 13 connecting the fixed plate 11 and the stop plate 12. The fixed plate 11 and the stop plate 12 are arranged horizontally, and the connecting plate 13 is arranged vertically. The first elongated slot 101 and the second elongated slot 102 are formed on the fixed plate 11, and the clearance window 103 is formed on the fixed plate 11 and extends through to the connecting plate 13. The stop plate 12 is used to extend into the battery compartment 2 to stop the forklift battery 3 inside the battery compartment 2. The stop bracket 10 has a simple structure and is easy to manufacture. At the same time, the aforementioned pin 23 is also fixed to the fixed plate 11. Of course, in other embodiments, the stop bracket 10 can also be implemented with other structures, as long as it can be installed on the frame 1 and extend into the battery compartment 2.

[0039] Specifically, both the first fixing member 21 and the second fixing member 22 are bolts, so that the tightness can be adjusted when they are used with the stop bracket 10; the assembly operation is also relatively simple. Of course, in other embodiments, the first fixing member 21 or the second fixing member 22 can also be other fixing members such as rivets or pins.

[0040] This embodiment also provides a forklift, including a frame 1, the frame 1 having a battery compartment 2, and a forklift battery 3 installed in the battery compartment 2; wherein, the frame 1 is provided with the aforementioned quick-release tilt stop device for the forklift battery, used to stop the forklift battery 3 in the battery compartment 2.

[0041] More preferably, a quick-release tilt stop device for the forklift battery is provided on at least one opposite side of the battery compartment 2. In this embodiment, a set of quick-release tilt stop devices for the forklift battery is provided on each opposite side of the battery compartment 2, and they are diagonally distributed, which can stop both sides of the forklift battery 3, and the effect is better.

[0042] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
