Description

Technical Field

[0001] This utility model relates to the field of forklift auxiliary structure technology, and in particular to a heat dissipation structure for forklifts. Background Technology

[0002] Forklifts are frequently used for transporting large items in warehouses and logistics. Their main power source is either an internal combustion engine or a battery. Forklifts are used for loading, unloading, stacking, and short-distance transport of goods with a certain weight and in bulk. They play an extremely important role in the logistics system of enterprises and are the mainstay of material handling equipment in today's society. They are used in various places such as stations, factories, warehouses, airports, and ports where logistics need to be transferred. With the increasing development of the social economy, most enterprises have basically abandoned manual operation when handling and stacking objects, and have thus chosen mechanized handling with forklifts as the main method.

[0003] Currently, when forklifts are used for material handling in workshops, warehouses, or factories, the batteries, which are part of the power system, generate significant heat due to the relatively enclosed environment. Forklift batteries are often centrally located, and current heat dissipation is insufficient. If heat dissipation is not timely and adequate, it can lead to serious consequences, such as component damage, battery overheating and bulging, and reduced lifespan of the equipment. Furthermore, when multiple forklift batteries are placed in a battery box, they may collide and be damaged during forklift travel over bumpy roads.

[0004] Therefore, in order to avoid the above situation, based on the shortcomings of the existing device reported by customers, the inventors made further improvements to overcome the above problems. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a heat dissipation structure for forklifts that effectively dissipates heat while avoiding high-temperature damage to the workpiece, thereby improving its service life.

[0006] The purpose of this utility model is achieved through the following technical solution: A heat dissipation structure for forklifts, including a battery, a fan, a mounting cabinet, and a limiting component;

[0007] The bottom plate of the installation cabinet is connected to the base, and the base is provided with a ventilation cavity. A fan is provided in the ventilation cavity, and multiple air holes are opened on the bottom plate. The fan blows air from the ventilation cavity through the air holes into the interior of the installation cabinet.

[0008] The mounting cabinet contains multiple battery components that are inserted and fixed by mounting brackets. The battery components are spaced apart by a certain distance, and a limiting component is provided in this distance. The limiting component includes a retaining block A, a retaining block B and a spring. The retaining block A and the retaining block B are respectively in close contact with the adjacent battery components, and the retaining block A and the retaining block B are connected by a spring. The multiple sets of limiting components are set between two adjacent battery components to prevent the battery components from moving or colliding due to bumps.

[0009] As a preferred technical solution of this application, the base is a rectangular groove structure, the groove is a ventilation cavity and multiple fan mounting holes are opened at the bottom of the groove, the multiple fans are arranged in an array in the fan mounting holes, and the upper part of the base is inserted and fixed to the mounting cabinet.

[0010] As a preferred technical solution of this application, the mounting cabinet is adapted to be inserted into the upper part of the base, and the mounting cabinet and the base are also fixed by a buckle, which facilitates installation and disassembly.

[0011] As a preferred technical solution of this application, the mounting frame is a trapezoidal frame with two downward inclined legs and a horizontal plate connecting the two legs. The bottom ends of the two legs are respectively fixed to the front and rear ends of the bottom plate inside the mounting cabinet. The horizontal plate has a mounting groove, and the lower part of the battery panel can be inserted into the mounting groove, so that the battery panel is suspended in the mounting cabinet by the mounting frame.

[0012] As a preferred technical solution of this application, the air vents include holes A and holes B. Multiple holes A are evenly distributed on the lower side of each mounting bracket, while multiple holes B are evenly distributed on the side of the area of ​​hole A. The edge of hole B protrudes upward and is connected to a duct. The duct extends to the upper middle part of the solar panel. The lower part of the battery components in the mounting cabinet is cooled through holes A, while the middle part of the solar panel is cooled through holes B.

[0013] As a preferred technical solution of this application, it also includes a top cover; the top cover is detachably mounted on the upper surface of the mounting cabinet, thereby preventing dust from entering the cabinet.

[0014] As a preferred technical solution of this application, multiple heat dissipation holes are evenly distributed on the four sides of the installation cabinet, which connect the installation cabinet with the outside world for effective heat dissipation.

[0015] As a preferred technical solution of this application, the front and rear ends of the clamping block A and clamping block B in the limiting component are respectively extended with long rectangular strips. At the same time, long grooves are opened in the left and right directions at corresponding positions on the front and rear sides of the mounting cabinet. The ends of the long rectangular strips are inserted into the long grooves and can move in the long grooves, thereby setting the limiting component on the upper part of the battery component and adapting to the battery component for limiting and fixing.

[0016] This utility model has the following advantages:

[0017] (1) It can effectively dissipate heat and avoid high temperature damage to the device workpiece;

[0018] Forklift batteries are often centrally located, and they generate significant heat during frequent use. Current cooling systems within the battery compartment are insufficient, potentially leading to damage or overheating and bulging. Therefore, this design incorporates a mounting cabinet with ventilation holes on all four sides, along with a fan at the bottom for airflow. Air is also supplied through holes A and B at the bottom and upper-middle sections of the cabinet, ensuring effective cooling of the batteries within the internal environment.

[0019] (2) Secure the battery components to prevent them from shaking or colliding, thus avoiding damage;

[0020] In this solution, a limiting component is set between the battery components to limit and fix the battery components. The mounting bracket is fixedly inserted into the lower part of the battery component, while the limiting component is set on the upper part of the battery block. Through the cooperation of the clamping block and the spring, the battery components are prevented from colliding and shaking due to external environmental conditions, such as road bumps or collisions with objects.

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0028] It should be noted that the orientation or positional relationship indicated by terms such as "left" and "right" is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the product of this invention is usually placed in during use, or the orientation or positional relationship that is commonly understood by those skilled in the art. Such terms are only for the convenience of describing this utility model and simplifying the description, and are not intended to 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 utility model.

[0029] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0030] Therefore, based on the above issues, please refer to Figure 1 This utility model proposes a heat dissipation structure for forklifts to solve the problem.

[0031] See Figures 1-5 The present embodiment proposes a heat dissipation structure for a forklift, including a mounting cabinet 1 and a battery 5, a fan 4 and a limiting component disposed in the mounting cabinet 1;

[0032] Among them, see Figures 1-2 The installation cabinet 1 is connected to a base 2. Multiple air holes are opened on the bottom plate of the installation cabinet 1. At the same time, the base 2 has a ventilation cavity 3. Multiple fans 4 are installed on the bottom surface of the ventilation cavity 3. By starting the fans 4, the fan blades rotate and the air passes through the ventilation cavity 3 to the air holes and enters the interior of the installation cabinet 1.

[0033] Among them, see Figures 3-5 Multiple battery components 5 are installed in the mounting cabinet 1 at a certain distance from each other, and are pressed and limited between the battery components 5 by a limiting component to prevent the battery components 5 from colliding and being damaged due to bumps and uneven roads; the limiting component includes two pressing blocks (pressing block A and pressing block B respectively), pressing block A and pressing block B are respectively pressed against the adjacent battery components 5, and pressing block A8 and pressing block B9 are connected by several springs 10;

[0034] First, install multiple battery components 5 into the mounting cabinet 1. Then, align and fix the mounting cabinet 1 with the bottom. At this time, the clamping block A and clamping block B in the limiting assembly are respectively attached to the opposite sides between adjacent battery components 5. At this time, while the battery components 5 are working and supplying power, the fan 4 is started, and the air passes through the ventilation cavity 3 to the air hole and enters the interior of the mounting cabinet 1 to dissipate heat from the battery components 5.

[0035] Forklifts often experience overheating of their power systems during handling operations, especially the battery systems in electric forklifts. Currently, forklift battery cooling is not comprehensive, and ineffective cooling can lead to battery overheating and bulging. While battery packs are often designed to keep batteries spaced apart to avoid overheating and heat transfer, forklifts may encounter bumpy roads during operation, causing internal battery collisions and damage. Therefore, this solution designs a cooling structure for forklifts. A base 2 with ventilation chambers 3 and a fan 4 is connected to a mounting cabinet 1, allowing airflow to the cabinet for cooling of the battery components 5. Simultaneously, a limiting component is installed to secure the battery components 5, preventing them from colliding or shaking due to external environmental conditions (such as road bumps or collisions with other objects).

[0036] In this embodiment, see Figure 2 and Figure 4 For the installation cabinet 1, the installation cabinet 1 is a rectangular cabinet with storage space inside for installing battery components 5. At the same time, multiple heat dissipation holes 14 are evenly distributed on the four sides of the installation cabinet 1 (front, back, left, and right). Since the bottom of the installation cabinet 1 is connected to the base 2 as an air inlet, its upper side is covered and sealed by the top cover 13 to prevent dust from entering the installation cabinet 1. Therefore, the battery components 5 inside the installation cabinet 1 are connected to the outside through the heat dissipation holes 14 on the four side walls for heat dissipation. The top cover 13 is detachably set on the upper surface of the installation cabinet 1. The upper surface of the front and rear edges of the installation cabinet 1 has protruding tracks. At the same time, the inner front and rear edges of the top cover 13 have corresponding long grooves, which can be used to fit the top cover 13 to the installation cabinet 1 for easy opening and closing of the installation cabinet 1 and to prevent dust from entering. At the same time, multiple air holes are provided on the lower surface of the installation cabinet 1, including holes A15 and B16. Air is sent into the installation cabinet 1 through holes A15 and B16 by the ventilation cavity 3 on the lower side.

[0037] Further, see Figure 2 and Figure 4 For the base 2, the base 2 includes a rectangular groove and a bracket. The rectangular groove is the ventilation cavity 3. The lower surface of the base 2 has brackets vertically downward at the four corners. The brackets are used to install the device at the power system of the forklift. The bottom surface of the ventilation cavity 3 has multiple fan 4 mounting holes. The multiple fans 4 are arranged in an array in the fan 4 mounting holes. The mounting cabinet 1 is inserted into and fixed on the upper part of the base 2. The mounting cabinet 1 and the base 2 are also fixed by a buckle, which makes it easier to install and disassemble the whole device.

[0038] It should be noted that the detachable top cover 13 also allows for easy removal and replacement of the battery component 5 when a single battery component 5 malfunctions, thus improving work efficiency.

[0039] Similarly, there are also heat dissipation structures that place the fan 4 on one side of the battery box. However, the structure in this solution is more optimized. The fan 4 is placed on the lower side of the mounting cabinet 1 where the battery components 5 are installed, which effectively prevents dust from entering the fan 4. At the same time, a ventilation cavity 3 is provided between the fan 4 and the mounting cabinet 1, so that the air can be slowly and orderly delivered into the mounting cabinet 1.

[0040] In this embodiment, see Figures 3-5 For the installation of battery components 5: multiple battery components 5 are inserted into the mounting cabinet 1 via mounting bracket 6. The mounting bracket 6 is a trapezoidal frame with legs and a horizontal plate. The two legs are inclined downwards, and the two ends of the horizontal plate are respectively connected to the two legs. The bottom ends of the legs are fixed to the inner bottom edge of the mounting cabinet 1, thereby fixing the mounting bracket 6 inside the mounting cabinet 1. There is a mounting groove on the horizontal plate, and the battery panel can be inserted into the mounting groove (at this time, the lower part of the battery panel is inserted into the mounting bracket 6 for fixation). The battery panel is suspended in the mounting cabinet 1 via the mounting bracket 6. (The suspended setting does not affect the normal operation of the air vents). At the same time, to prevent the upper part of the battery panel from shaking, a limiting component is set to limit the battery panel by means of spring 10 and clamping member. The front and rear ends of clamping block A and clamping block B in the limiting component are respectively extended with long rectangular strips 12. At the same time, long slots 11 are opened in the left and right directions at corresponding positions on the front and rear sides of the mounting cabinet 1. The ends of the long rectangular strips 12 are inserted into the long slots 11 and can move in the long slots 11, thereby setting the limiting component on the upper part of the battery component 5 and adapting to the battery component 5 for limiting and fixing.

[0041] Furthermore, the ventilation holes include two types: holes A15 and holes B16. Multiple holes A15 are evenly distributed below the mounting bracket 6 of a single battery component 5 (at this time, the mounting bracket 6 is suspended in the mounting cabinet 1 to avoid conflict with the holes A15). At the same time, multiple holes B16 are evenly distributed on the sides of the area of ​​holes A15. A duct is provided on the upper side of hole B16, protruding around the circumference of hole B16. The duct extends to the upper middle part of the battery panel. The lower part of the battery component 5 in the mounting cabinet 1 is cooled through holes A15, while the middle part of the battery panel is cooled through holes B16. This avoids the problem of insufficient heat dissipation in the existing battery box, and can dissipate heat from the battery component 5 more evenly and comprehensively, preventing it from being damaged by heat.

[0042] Furthermore, two handles 7 are provided on the inner surface of the left and right side panels of the mounting cabinet 1, protruding inward. The tail end of the handle 7 contacts the battery component 5 located at the head and tail, thereby pressing the battery component 5 against the head. When the device needs to be disassembled, the handle 7 can also be used to facilitate lifting and moving.

[0043] It should be noted that the heat dissipation holes 14 on the side panel of the mounting cabinet 1 do not interfere with the handle 7 and the long slot 11 fixedly connected to the inside of the mounting cabinet 1, thereby avoiding the opening of the heat dissipation holes 14 from affecting the normal installation of the handle 7 and the long slot 11.

[0044] Currently, when forklifts are used frequently in workshops, factories, or warehouses, their power batteries may overheat. Since forklift batteries are often housed in battery boxes, heat dissipation is insufficient, potentially leading to battery component damage or overheating and bulging, reducing the lifespan of the device. Furthermore, forklifts inevitably encounter bumpy roads or sudden stops and starts during operation, causing batteries to collide. Therefore, this solution incorporates a fan 4 structure on the underside of the mounting cabinet 1 containing the battery components 5, transmitting air into the cabinet 1. Limiting components, through the cooperation of two clamping blocks and springs 10, effectively secure the multiple battery components 5 inside, preventing them from colliding or tilting.

[0045] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
