Description

Technical Field

[0001] The utility model relates to the field of vehicles, in particular to a forklift. Background Art

[0002] Electric forklifts have the advantages of zero emissions, low noise, flexibility, and high efficiency. At the same time, they can adapt to different working environments and task requirements, which is conducive to improving logistics efficiency and reducing labor costs. They are widely used in warehousing, logistics, manufacturing and other fields.

[0003] However, in the actual operation of electric forklifts, the forklifts may shake or bump when inserting or removing heavy objects or driving on potholes. The battery installed on the forklift frame will move relative to the frame as the body shakes, making it easy for the battery to collide with the frame and cause damage. In addition, due to the movement of the battery, the power interface between the battery and the forklift may become loose, which may easily cause the forklift to lose power and affect the normal operation of the forklift. Utility Model Content

[0004] In view of this, the present application provides a forklift, which solves the above technical problems by improving the limiting assembly on the forklift so that the limiting assembly can limit the battery so that the battery does not shake with the shaking of the vehicle body.

[0005] An embodiment of the present application provides a forklift, which includes a frame, a battery and a limit assembly, wherein the frame is provided with a accommodating cavity, and the battery is placed in the accommodating cavity, and the limit assembly has a locked state and an active state, and the limit assembly also includes a first mounting seat, a second mounting seat and a connecting rod, wherein the first mounting seat is provided with a locking portion, the second mounting seat is provided with a mounting portion, and the connecting rod is flipped and connected to the mounting portion; the connecting rod includes a first end and a second end arranged opposite to each other, the first end is rotatably connected to the mounting portion, and the second end is detachably connected to the locking portion; when the limit assembly is in the locked state, the second end is connected to the locking portion; when the limit assembly is in the active state, the second end is away from the locking portion.

[0006] In the present application, it should be understood that the connection state between the battery and the frame is synchronized with the connection state of the limit assembly. When the limit assembly is in a locked state, the battery and the frame are relatively fixed; when the limit assembly is in an active state, the battery can be pulled out of or put into the accommodating cavity of the frame. The forklift in the present application mainly improves the limit assembly, by switching the connection state between the connecting rod and the locking part in the limit assembly, so that the limit assembly can switch between the locked and active states. Therefore, after the limit assembly in the present application is installed on the forklift, it can meet the disassembly and assembly requirements between the battery and the frame, and when the limit assembly is in a locked state, the battery and the frame are stably connected through the limit effect formed by the limit assembly, thereby ensuring the operation safety and operation effect of the forklift.

[0007] In some specific embodiments, the locking portion is provided with a locking cavity. When the limit assembly is in the locked state, the second end is inserted into the locking cavity. At this time, the connecting rod abuts against the inner wall of the locking cavity, and the locking cavity can form a certain limiting effect on the connecting rod, so that the connecting rod in the locked state of the limit assembly can be stably connected to the locking portion.

[0008] In some specific embodiments, the locking portion is further provided with a notch, and the locking cavity is connected to the outside through the notch. When the limiting component switches from the active state to the locked state, the second end enters the locking cavity from the notch, thereby facilitating the switching of the state of the limiting component.

[0009] In some specific embodiments, the limit assembly also includes a fastener, which is installed at the second end of the connecting rod and moves synchronously with the connecting rod. When the limit assembly is in a locked state, the fastener is fixed to the locking part, thereby enhancing the connection strength between the connecting rod and the locking part.

[0010] In some specific embodiments, the fastener includes a fastening portion and a guide portion that are connected to each other, and the fastening portion is closer to the second end of the connecting rod relative to the guide portion, wherein the guide portion is conical, and an outer wall surface of the guide portion gradually approaches a central axis of the guide portion in a direction from the side where the fastening portion is located to the side where the mounting portion is located. In this way, when the fastener is connected to the locking portion, if relative movement occurs between the fastener and the locking portion, the guide portion can guide the movement of the fastener so that the fastening portion can be accurately connected to the locking portion, thereby improving the connection effect between the fastener and the locking portion.

[0011] In some specific embodiments, the connecting rod is provided with a threaded portion, and the interior of the fastening portion and the guide portion is at least partially provided with an internal thread to screw the threaded portion. In this way, when the limit assembly switches the connection state, the operating object can adjust the relative position of the fastener on the connecting rod to adjust the connection state between the connecting rod and the locking portion.

[0012] In some specific embodiments, the fastener also includes a head, and a limiting annular surface is formed between the head and the fastening part. When the limiting assembly is in a locked state, the head of the fastener is located on the outside of the locking part, and the limiting annular surface abuts against the end face of the locking part to prevent the fastener from sliding away from the locking part, causing the locking part and the fastening part to lose the connection relationship.

[0013] In some specific embodiments, the fastener includes an operating lug and a head, and the operating lug is disposed on an outer surface of the head to facilitate an operating subject to use the fastener.

[0014] In some specific embodiments, the mounting portion is connected to a rotating shaft, and a connecting rod is provided with a connecting through hole along the central axis direction of the rotating shaft. The rotating shaft passes through the connecting through hole so that the connecting rod can be rotated to connect to the mounting portion, thereby realizing a flip connection between the connecting rod and the second mounting seat.

[0015] In some specific embodiments, an abutting protrusion is convexly provided on the inner wall of the accommodating cavity. When the battery is placed in the accommodating cavity, the abutting protrusion abuts against the upper surface of the battery to prevent the battery from jumping in the accommodating cavity due to the bumps of the forklift.

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application is clearly and completely described below in conjunction with the drawings of the embodiments of the present application. Obviously, the described embodiments are only embodiments of a part of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of this application.

The words "one", "an" or "the" and the like used in this application do not indicate a quantitative limitation, but are only used to indicate the presence of at least one. The words "include" or "comprise" and the like mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. The words "connect" or "connected" and the like are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect.

[0030] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0031] The following will be combined with the embodiments of this application Figures 1 to 10 , clearly and completely describe each technical solution in the embodiments of the present application, wherein: Figure 1 , Figure 3 , Figure 7 and Figure 8The movable directions of the battery 10 relative to the frame 20 are schematically marked: the lateral direction (E) and the vertical direction (F). Fig.10 The upper and lower directions of the battery 10 after being placed in the accommodating cavity 21 are schematically marked for reference to facilitate understanding of the contents of the embodiment.

[0032] Please refer to Figures 1 to 4 The present application mentions a forklift, which includes a frame 20, a battery 10 and a limit assembly 30. The frame 20 is provided with a receiving cavity 21 (refer to Fig. 9 , Fig. 9 The battery 10 is placed in the accommodating cavity 21. The limiting assembly 30 is installed adjacent to the cavity entrance of the accommodating cavity 21. The limiting assembly 30 includes a first mounting seat 31, a second mounting seat 32 and a connecting rod 33. The first mounting seat 31 is used to connect with the battery 10, and the first mounting seat 31 is provided with a locking portion 311. The second mounting seat 32 is used to connect with the frame 20. The second mounting seat 32 is provided with a mounting portion 321. The connecting rod 33 includes a first end 333 and a second end 334 that are arranged opposite to each other, the first end 333 is rotatably connected to the mounting portion 321, and the second end 334 is detachably connected to the locking portion 311. When the second end 334 of the connecting rod 33 is connected to the locking portion 311, the limiting assembly 30 is in a locked state (corresponding to reference Figure 1 and Figure 2 When the connecting rod 33 is separated from the locking portion 311, the limiting assembly 30 is in an active state (corresponding to Figure 3 and Figure 4 ).

[0033] Thus, in the present application, in the locked state of the limit assembly 30, a stable connection can be achieved between the battery 10 and the frame 20. In actual application, the user can first adjust the limit assembly 30 to the active state, put the battery 10 into the accommodating cavity 21 of the frame 20, and adjust the limit assembly 30 to the locked state again, so that the battery 10 and the frame 20 are relatively fixed. Due to the limiting effect between the locking portion 311 and the connecting rod 33, the battery 10 will not rotate or move displaced relative to the frame 20, so that the battery 10 and the frame 20 can maintain a stable relative position, which on the one hand meets the demand for rapid disassembly and assembly between the battery 10 and the frame 20, and on the other hand improves the connection stability between the battery 10 and the frame 20. In this way, during the actual use of the forklift, the forklift will not experience sudden power failure or battery 10 jumping out, and the battery 10 is not easy to collide with the inner wall of the accommodating cavity 21, which improves the safety of the forklift and the operation effect.

[0034] It should be noted that the reason why the disassembly and assembly requirements of the battery 10 and the frame 20 must be met is to meet the charging and replacement requirements of the battery 10 on the forklift. At this time, the user needs to take out the battery 10 on the forklift and move it to a charging place or a battery 10 recycling place. For ease of understanding, the charging of the battery 10 is taken as an example for specific description. In this application, when the battery 10 of the forklift needs to be charged, the user first switches the limit assembly 30 from the locked state to the active state, then pulls the battery 10 out of the accommodating chamber 21, and then charges the battery 10. After the battery 10 is fully charged, the battery 10 is put back into the accommodating chamber 21, and the limit assembly 30 is adjusted to the locked state again to ensure a stable connection between the battery 10 and the frame 20. Therefore, in order to meet the requirements of assembly and disassembly between the battery 10 and the frame 20, the forklift in the present application makes the limit assembly 30 have a locked state and an active state accordingly. When in use, the user can only adjust the connecting rod 33 to change the connection relationship between the connecting rod 33 and the locking portion 311, thereby switching the limit assembly 30 between the locked state and the active state. Therefore, the limit assembly 30 can assist the user to adjust the connection relationship between the battery 10 and the frame 20 conveniently and quickly.

[0035] In addition, since the first end 333 of the connecting rod 33 is rotatably connected to the mounting portion 321 of the second mounting seat 32, the connecting rod 33 and the second mounting seat 32 are always connected, so the limit assembly 30 on the forklift can maintain its integrity for a long time, and any part of the assembly is difficult to lose, making it difficult for the above-mentioned limit assembly 30 to become unusable due to the loss of a part.

[0036] It is worth mentioning that the limiting assembly 30 is not limited to forklifts, but can also be applied to other vehicles, so that two structures that need to be disassembled and assembled can achieve a stable connection effect.

[0037] Please refer to Figures 7 to 10 In some embodiments, an inner wall of the accommodating cavity 21 is provided with an abutting protrusion 211. When the battery 10 is placed in the accommodating cavity 21, the abutting protrusion 211 abuts against the upper surface of the battery 10. Under the joint constraints of the abutting protrusion 211 and the limiting assembly 30, the battery 10 can be stably placed in the accommodating cavity 21 of the frame 20.

[0038] Specifically, at the cavity opening of the accommodating cavity 21, the mutual constraint between the battery 10 and the frame 20 is realized by the limit assembly 30, that is, when the limit assembly 30 is switched to the locked state, the connecting rod 33 locks the connecting locking portion 311, so that the battery 10 and the frame 20 are mutually locked; inside the cavity of the accommodating cavity 21, the abutting convex portion 211 abuts against the upper surface of the battery 10, so that along the vertical direction F shown in the figure, the abutting convex portion 211 and the bottom wall of the accommodating cavity 21 (here refers to the accommodating cavity) are abutted. 21 and the inner wall connected to the lower surface of the battery 10) together form a restraining effect on the battery 10. In this way, when the forklift is bumpy, due to the joint restraining effect of the abutting protrusion 211 and the limiting assembly 30, the battery 10 is stably placed in the accommodating cavity 21, there is no relative displacement between the battery 10 and the frame 20, and the battery 10 will not jump relative to the frame 20; if the forklift stops suddenly, due to the restraining effect of the limiting assembly 30, the battery 10 will not be separated from the cavity opening of the accommodating cavity 21 due to inertia.

[0039] Please continue to refer to Figure 2 and Figure 4 In some embodiments, the locking portion 311 is provided with a locking cavity 311a. When the limiting assembly 30 is in the locked state, the second end 334 of the connecting rod 33 is inserted into the locking cavity 311a. In this way, the inner wall of the locking cavity 311a forms a certain limiting effect on the connecting rod 33. When the limiting assembly 30 is in the locked state, the connecting rod 33 and the inner wall of the locking cavity 311a can form abutment effect, thereby enhancing the connection strength between the connecting rod 33 and the locking portion 311, improving the locking effect of the limiting assembly 30, and thus improving the locking effect between the battery 10 and the frame 20.

[0040] Please continue to refer to Figure 2 and Figure 4 Furthermore, in some embodiments, the locking portion 311 is further provided with a notch 311b, and the locking cavity 311a is connected to the outside through the notch 311b, wherein the diameter of the notch 311b is smaller than the inner diameter of the locking cavity 311a, and when the position-limiting assembly 30 switches from the active state to the locked state, the connecting rod 33 enters the locking cavity 311a from the notch 311b to achieve the state switching of the position-limiting assembly 30. Such a configuration reduces the difficulty of operation of the position-limiting assembly 30 for the user, and when the user needs to switch the connection state of the position-limiting assembly 30, it is only necessary to adjust the connecting rod 33 to enter or leave the locking cavity 311a from the notch 311b, without any additional operations.

[0041] Furthermore, in some embodiments, the diameter of the notch 311b is smaller than the inner diameter of the locking cavity 311a, and the cavity walls of the locking cavity 311a distributed on both sides of the notch 311b can be relatively separated under the abutment of the connecting rod 33, so that the connecting rod 33 can be squeezed into the locking cavity 311a from the notch 311b, and return to its original position after the connecting rod 33 enters the locking cavity 311a. In this way, when the user does not apply force to adjust the connecting rod 33, the connecting rod 33 will not leave the locking cavity 311a from the notch 311b due to the limitation of the cavity wall of the locking cavity 311a, and the limit assembly 30 can maintain a stable locking state.

[0042] Additionally, in some embodiments, the first mounting seat 31 is provided with a first mounting plate 312, the locking portion 311 is protruding from the surface of the first mounting plate 312, and the first mounting plate 312 is used to connect to the end surface of the battery 10; the second mounting seat 32 is provided with a second mounting plate 324, the mounting portion 321 is provided on the surface of the second mounting plate 324, and the second mounting plate 324 is used to connect to the surface of the frame 20 so that the connecting rod 33 can rotate to connect the locking portion 311, wherein, when the second mounting plate 324 is connected to the surface of the frame 20, the mounting portion 321 and the frame 20 are respectively located on opposite sides of the second mounting plate 324.

[0043] Based on the above embodiment, in an implementable installation method of the limit assembly 30, the first mounting plate 312 and the second mounting plate 324 in the limit assembly 30 are vertically arranged, that is, the mounting surface of the first mounting plate 312 (the end surface of the battery 10) and the mounting surface of the second mounting plate 324 (the surface of the frame 20) are vertically arranged, so that when the connecting rod 33 is connected to the locking part 311, the abutting surfaces of the connecting rod 33 and the locking part 311 are vertically arranged on the central axis of the connecting rod 33.

[0044] Please refer to Figures 1 to 5 In some embodiments, the limit assembly 30 further includes a fastener 34, which is mounted on the second end 334 of the connecting rod 33 and moves synchronously with the connecting rod 33. When the limit assembly 30 is in a locked state, the fastener 34 is fixed to the locking portion 311, thereby achieving a fixed connection between the battery 10 and the frame 20. In the actual production process, it is difficult to fully adapt the dimensions of the connecting rod 33 and the locking portion 311. After the connecting rod 33 is connected to the locking portion 311, there may be a gap between the two, thereby affecting the connection effect between the two. The fastener 34 can fill the connection gap between the two, that is, the fastener 34 can fit the surface of the locking portion 311. Because the fastener 34 is mounted on the connecting rod 33, it is equivalent to reducing the connection gap between the connecting rod 33 and the locking portion 311, thereby enhancing the connection strength between the connecting rod 33 and the locking portion 311.

[0045] Please refer to Figure 5 and Figure 6Further, in some embodiments, the connecting rod 33 is provided with a threaded portion 331 on one side close to the second end 334, and the interior of the fastening portion 341 and the guide portion 342 is at least partially provided with internal threads to screw the threaded portion 331, so that the fastener 34 can move along the extension direction of the threaded portion 331, so that the limit assembly 30 can adapt to more application scenarios. For ease of understanding, the above embodiments are now described in combination with actual application scenarios in life. When the user places the battery 10 into the accommodating cavity 21, the limit assembly 30 needs to be switched to the locked state. At this time, in order to allow the second end 334 to smoothly enter the accommodating cavity 21, the user needs to adjust the relative position of the fastener 34 on the connecting rod 33, that is, rotate the fastener 34 to move the fastener 34 toward the side where the second end 334 is located, so that the fastener 34 does not interfere with the connecting rod 33 entering the locking cavity 311a; when the connecting rod 33 enters the locking cavity 311a, the user rotates the fastener 34 again to move the fastener 34 away from the second end 334 until the fastener 34 and the locking portion 311 are locked and connected. At this time, the fastener 34 at least partially enters the locking cavity 311a, and the connecting rod 33 and the locking portion 311 are locked and connected under the action of the fastener 34. When the user needs to remove the battery 10, the user needs to first rotate the fastener 34 to move it toward the side close to the second end 334. When the fastener 34 is out of the locking cavity 311a, the connecting rod 33 can be rotated out of the locking cavity 311a. At this time, the fastener 34 will not interfere with the rotation of the connecting rod 33.

[0046] In summary, the user can adjust the relative position of the fastener 34 on the connecting rod 33 by twisting the fastener 34, so that the fastener 34 will not interfere with the rotation of the connecting rod 33. In addition, in the length direction of the connecting rod 33, the internal thread structure of the fastener 34 and the threaded portion 331 form mutual interference, that is, when the fastener 34 is connected to the threaded portion 331, the fastener 34 cannot move along the rod body direction, so that when the user twists the fastener 34 to a certain position of the threaded portion 331, the fastener 34 will not slide to other positions of the threaded portion 331 along the length direction of the connecting rod 33 due to its own weight. In the process of the user rotating the connecting rod 33, the fastener 34 can move synchronously with the connecting rod 33 and will not interfere with the locking connection between the connecting rod 33 and the locking portion 311.

[0047] Please refer to Figure 1 , Figure 2 and Figure 5 In some embodiments, the fastener 34 includes a fastening portion 341 and a guide portion 342 connected to each other, the fastening portion 341 is closer to the free end of the connecting rod 33 relative to the guide portion 342, wherein the guide portion 342 is conical, and along the side where the fastening portion 341 is located in the direction of the side where the mounting portion 321 is located, the outer wall surface of the guide portion 342 gradually approaches the central axis of the guide portion 342.

[0048] After the connecting rod 33 moves to connect to the locking portion 311, the user needs to adjust the relative position of the fastener 34 on the connecting rod 33 to enhance the connection strength between the connecting rod 33 and the locking portion 311. In this partial embodiment, during the process of the fastener 34 moving to connect to the locking portion 311, the guide portion 342 first moves close to the locking portion 311, and then the fastening portion 341 connects to the locking portion 311 to achieve the connection between the fastener 34 and the locking portion 311. The conical guide portion 342 is provided to enhance the alignment effect between the fastening portion 341 and the locking portion 311. When the connecting rod 33 and the locking portion 311 are relatively misaligned, due to the inclined side of the guide portion 342, during the movement of the guide portion 342 relative to the locking portion 311, the mutual abutment between the two can guide the fastening portion 341 to move accordingly and align with the connecting locking portion 311, thereby linking the connecting rod 33 to align with the connecting locking portion 311, so that a good connection effect can be achieved between the connecting rod 33 and the locking portion 311.

[0049] Please refer to Figure 1 , Figure 2 and Figure 5 In some embodiments, the fastener 34 includes a head 345, and a limiting annular surface 343 is formed between the head 345 of the fastener 34 and the fastening portion 341. When the limiting assembly 30 is in a locked state, the head 345 of the fastener 34 is located on the outside of the locking portion 311, and the limiting annular surface 343 abuts against the end surface of the locking portion 311. In this way, when the fastener 34 and the locking portion 311 are connected, the abutment between the limiting annular surface 343 and the end surface of the locking portion 311 can prompt the user that the connection between the fastener 34 and the locking portion 311 is completed, and the user can stop fastening. On the other hand, the limiting annular surface 343 can prevent excessive movement between the fastening portion 341 and the locking portion 311. When the fastening portion 341 and the locking portion 311 are connected, due to the blocking effect formed between the limiting annular surface 343 and the locking portion 311, the fastening portion 341 will no longer continue to move along the rod body direction of the connecting rod 33. Therefore, the fastening portion 341 will not continue to move relative to the locking portion 311 to disengage from the locking portion 311. In this way, the connection strength between the fastener 34 and the locking portion 311 is guaranteed, so that the battery 10 and the frame 20 can be stably connected.

[0050] Please refer to Figure 5 The fastener 34 is provided with an operating lug 344, and the operating lug 344 is provided on the outer surface of the head 345. In this way, it is convenient for the user to rotate the fastener 34. The user can directly twist the fastener 34 by hand without using additional auxiliary tools, thereby reducing the difficulty of operating the fastener 34.

[0051] Furthermore, in some embodiments, the operating lug 344 extends in a direction away from the central axis of the head 345, and multiple operating lugs 344 are distributed at intervals on the periphery of the head 345. In this way, when the user rotates the fastener 34 through the operating lug 344, due to the large torque, the user does not need to use a lot of force to rotate the fastener 34, which reduces the operating difficulty of the fastener 34 to a certain extent.

[0052] Please refer to Figure 2 , Figure 4 and Figure 6 In some embodiments, the mounting portion 321 is connected to a rotating shaft 321a, and the connecting rod 33 is provided with a connecting through hole 332 along the central axis direction of the rotating shaft 321a. The rotating shaft 321a is penetrated by the connecting through hole 332 so that the connecting rod 33 can rotate and connect to the mounting portion 321. In this way, the connecting rod 33 is flipped through the rotating shaft 321a to connect to the second mounting seat 32. There is a rotational friction between the connecting rod 33 and the rotating shaft 321a, and there is almost no direct rotational friction between the second mounting seat 32 and the connecting rod 33. In this way, the second mounting seat 32 is subject to less wear, and the rotating shaft 321a, due to its own functionality, has its material and surface processed to reduce the rotational friction between it and the rotating shaft 321a, and the service life of the rotating shaft 321a is generally longer. In summary, such a configuration prolongs the service life of the limit assembly 30 to a certain extent.

[0053] In some embodiments, the second mounting seat 32 is provided with two connecting lugs 323, and the rotating shaft 321a is installed between the two connecting lugs 323. The rotating shaft 321a is inserted into the connecting through hole 332 so that the first end 333 of the connecting rod 33 can rotate the connecting rotating shaft 321a. In this way, the first end 333 can be placed in the space between the two connecting lugs 323, which reduces the total volume of the connecting rod 33 and the second mounting seat 32 after connection to a certain extent, thereby reducing the production cost of the limit assembly 30.
