Description
Technical Field
[0001] The utility model relates to the technical field of forklifts, and particularly relates to a forklift with a laterally removable power battery. Background Technique
[0002] With the rapid development of industrial automation and the logistics industry, forklifts, as an important part of material handling equipment, have an increasing usage frequency and application scope. Traditional battery forklifts are widely used in fields such as warehousing, manufacturing, and logistics due to their advantages of cleanliness, environmental friendliness, and low noise. However, the battery replacement method of traditional battery forklifts is mainly achieved by hoisting. This method is not only complex and time-consuming in operation, but also requires special hoisting equipment and personnel, increasing the usage cost and operation difficulty.
[0003] For some users who need to work continuously for a long time, such as users with three-shift operations, they need to frequently replace the battery to ensure the continuous operation of the forklift. In this case, the traditional hoisting battery replacement method is particularly inefficient, seriously affecting work efficiency. At the same time, due to space limitations or other special requirements in some specific places, a more efficient and convenient battery replacement method is also needed to adapt to their special operating environment. To solve this problem, some forklift models with laterally removable batteries have been developed in the industry.
[0004] The forklift models with laterally removable batteries are provided with a battery compartment on the side of the forklift, enabling the battery to be removed and replaced from the side. This design improves the battery replacement efficiency to a certain extent and reduces the dependence on hoisting equipment and personnel. However, since the battery needs to be removed from the side, the right side of the forklift must be opened to facilitate the smooth removal of the battery. This design has significantly reduced the strength of the forklift frame on the right side, thereby affecting the structural strength and stability of the entire vehicle.
[0005] In some complex working conditions, such as on rough ground or in an operating environment that requires frequent turning, the frame and covering parts are prone to deformation, affecting the appearance quality and service life of the forklift. More seriously, the reduction in the frame strength may lead to situations such as tearing of the frame, posing a great potential safety hazard. Users not only have to face frequent repairs and maintenance during the use process, but also bear the risks brought by safety issues.
[0006] Therefore, how to achieve the lateral area power battery of the forklift while ensuring the structural strength of the right side of the forklift frame has become an urgent technical problem to be solved. Content of the Utility Model
[0007] The main purpose of the utility model is to provide a forklift with a laterally removable power battery, aiming to achieve the lateral area power battery of the forklift while ensuring the structural strength of the right side of the forklift frame.
[0008] To achieve the above object, the present utility model provides a forklift with a laterally removable power battery, comprising:
[0009] A frame body, on one side of which there is a battery compartment for accommodating a power battery. A battery removal opening is provided on the side wall of the battery compartment for removing the power battery from the side. An avoidance opening is provided at the bottom of the battery compartment to facilitate the operation of the power battery in the battery compartment. A strengthening beam is provided at the top of the battery removal opening of the battery compartment to connect the two side walls of the battery compartment and improve the structural strength of the forklift frame.
[0010] In an embodiment of the present application, a limiting base is provided on one side of the battery removal opening of the battery compartment, and a rotating limiting block is provided on the limiting base and can be unfolded to limit the battery in the battery compartment.
[0011] In an embodiment of the present application, the rotating limiting block is electrically connected to the forklift switch. When the rotating limiting block is in a contracted state, the forklift switch is in a closed state.
[0012] In an embodiment of the present application, a door body for opening or closing the battery removal opening of the battery compartment is further connected to the frame body.
[0013] In an embodiment of the present application, a door lock assembly is provided on the door body to lock the door body to the frame body.
[0014] In an embodiment of the present application, a first windproof bracket into which the first end of a windproof hook can be inserted is further provided on the frame body, and a second windproof bracket into which the second end of the windproof hook can be inserted is provided on the door body.
[0015] In an embodiment of the present application, a limiting member is provided at the bottom of the battery compartment and can cover the periphery of the bottom of the power battery pack to limit the displacement of the power battery pack.
[0016] In an embodiment of the present application, a wire harness routing board is connected to the frame body, and the wire harness axis board is located on the side of the strengthening beam close to the battery compartment.
[0017] In an embodiment of the present application, when the power battery is a lithium battery, a counterweight is provided on the side of the frame body away from the vehicle head.
[0018] In an embodiment of the present application, a proximity switch is further provided on the door body, and the proximity switch is located on one side of the battery removal opening of the battery compartment.
[0019] With the above technical solution, the traditional battery replacement method usually requires a hoisting device, which is not only complex to operate but also time-consuming. By designing a side battery outlet, operators can use a pallet truck or forklift to quickly replace the battery from the side, greatly improving work efficiency, especially suitable for users with three-shift operations that require frequent battery replacement. By setting a reinforced tension beam at the top of the battery compartment outlet, the two side walls of the battery compartment are effectively connected to form a strong frame structure. The design of the reinforced tension beam not only improves the strength of the battery compartment itself but also enhances the structural strength of the entire vehicle frame, preventing the vehicle frame from deforming or being damaged under complex working conditions. The avoidance opening design at the bottom of the battery compartment allows operators to easily operate and maintain the battery without opening other covers or seat box lids, simplifying the operation steps and improving the convenience and safety of operation. This design can adapt to different types of power batteries, including lead-acid batteries and lithium batteries. By optimizing the battery compartment and counterweight design, different battery types can be interchanged without modifying the vehicle frame structure, meeting the market demand for converting lead-acid batteries to lithium batteries.

[0024] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following will describe the present invention in detail with reference to the drawings and embodiments. It should be understood that the following specific embodiments are only used to explain the present invention and do not limit the present invention.
[0025] As Figures 1 to 2 , in order to achieve the above objectives, the present invention provides a forklift with side-accessible power batteries, including:
[0026] The frame body 10, on one side of the frame body 10, there is a battery compartment 21 for accommodating a power battery. On the side wall of the battery compartment 21, there is an access opening for taking out the power battery from the side. At the bottom of the battery compartment 21, there is an avoidance opening for facilitating the operation of the power battery in the battery compartment 21. At the top of the access opening of the battery compartment 21, there is a strengthening beam 20 connecting the two side walls of the battery compartment 21 to enhance the structural strength of the forklift frame.
[0027] Specifically, the frame body 10 is the main load-bearing structure of the forklift, made of high-strength steel to ensure that it will not deform or be damaged during the process of carrying heavy loads and long-term use. On one side of the frame body 10, there is a battery compartment 21 for accommodating a power battery. The battery compartment 21 is a dedicated space for placing the power battery. Its side wall is provided with an access opening, which is arranged on the side wall of the battery compartment 21 for taking out the power battery from the side. The design of the access opening enables the battery to be easily shoveled out from the side by a pallet truck or a forklift, simplifying the battery replacement process. The avoidance opening is arranged at the bottom of the battery compartment 21, enabling the operator to conveniently operate and maintain the battery. The design of the avoidance opening takes into account the convenience and safety of the operation.
[0028] The strengthening beam 20 connects the two side walls of the battery compartment 21 to enhance the structural strength of the forklift frame. The strengthening beam 20 is made of high-strength steel and is fixed to the top of the battery compartment 21 by welding or bolt connection to form a solid frame structure. The existence of the strengthening beam 20 effectively disperses the forces on the battery compartment 21 and the frame body 10, preventing the frame from deforming or being damaged under complex working conditions.
[0029] Adopting the above technical solution, the traditional battery replacement method usually requires a hoisting device, which is not only complex to operate but also time-consuming. By designing an access opening for side battery taking, the operator can quickly replace the battery from the side using a pallet truck or a forklift, greatly improving the work efficiency, especially suitable for users with three-shift operations that require frequent battery replacement. By arranging the strengthening beam 20 at the top of the access opening of the battery compartment 21, the two side walls of the battery compartment 21 are effectively connected to form a solid frame structure. The design of the strengthening beam 20 not only improves the strength of the battery compartment 21 itself but also enhances the structural strength of the entire frame, preventing the frame from deforming or being damaged under complex working conditions. The design of the avoidance opening at the bottom of the battery compartment 21 enables the operator to conveniently operate and maintain the battery without opening other covers or seat box lids, simplifying the operation steps and improving the convenience and safety of the operation. This design can adapt to different types of power batteries, including lead-acid batteries and lithium batteries. By optimizing the design of the battery compartment 21 and the counterweight, different battery types can be interchanged without modifying the frame structure, meeting the market demand for converting lead-acid batteries to lithium batteries.
[0030] In an embodiment of the present application, a limiting base 31 is provided on one side of the outlet of the battery compartment 21, and a rotating limiting block 32 that can be unfolded to limit the battery in the battery compartment 21 is provided on the limiting base 31.
[0031] Specifically, the limiting base 31 is arranged on one side of the outlet for fixing and supporting the rotating limiting block 32. The limiting base 31 is a fixed structural member. It is made of a metal material, such as an aluminum alloy material or a alloy steel material, to ensure its strength and stability. The rotating limiting block 32 is installed on the limiting base 31 and can be unfolded to limit the battery in the battery compartment 21. The rotating limiting block 32 is connected to the limiting base 31 through a hinge or a bearing and can rotate freely. The rotating limiting block 32 is made of metal (such as stainless steel) or high-strength plastic to ensure its durability and reliability.
[0032] The limiting base 31 is fixed on one side of the outlet of the battery compartment 21 and can be connected by means of screws, welding, etc. to ensure its firmness. The rotating limiting block 32 is connected to the limiting base 31 through a hinge or a bearing to ensure that it can be unfolded or retracted when needed.
[0033] With the above technical solution, by arranging the limiting base 31 on one side of the outlet of the battery compartment 21 and installing the rotating limiting block 32 on the limiting base 31, the structure is compact and occupies little space. The rotating limiting block 32 can be freely unfolded and retracted, and the user can complete the limiting and release with simple operations when replacing the battery, which is convenient and fast. The limiting base 31 and the rotating limiting block 32 are made of high-strength materials to ensure their reliability and durability during long-term use. When the rotating limiting block 32 is unfolded, it can effectively limit the battery and prevent the battery from moving or falling off in the battery compartment 21, protecting the safety of the battery and the device.
[0034] In an embodiment of the present application, the rotating limiting block 32 is electrically connected to the forklift switch, and when the rotating limiting block 32 is in a retracted state, the forklift switch is in a closed state.
[0035] Specifically, the rotating limiting block 32 is electrically connected to the forklift switch. When the rotating limiting block 32 is in a retracted state, the forklift switch is in a closed state. When the rotating limiting block 32 is in an extended state, the forklift switch is in an open state.
[0036] With the above technical solution, when the rotating limiting block 32 is in a retracted state, the forklift switch is automatically closed to prevent misoperation and improve safety.
[0037] In an embodiment of the present application, a door body 40 for opening or closing the outlet of the battery compartment 21 is further connected to the vehicle frame body 10.
[0038] Specifically, the frame body 10 is made of high-strength aluminum alloy material to ensure high-strength supporting ability and provide support and stability for the entire structure. The door body 40 is made of the same material as the frame body 10, such as high-strength aluminum alloy, to ensure overall consistency and strength. The door body 40 is connected to the frame body 10 through hinges or sliding rails, enabling opening and closing operations, which are used to open or close the access opening of the battery compartment 21 and protect the internal components of the battery compartment 21.
[0039] The door body 40 is connected to the frame body 10 through hinges or sliding rails. The hinge can be a metal hinge, and the sliding rail can be a high-strength plastic or metal sliding rail.
[0040] Adopting the above technical solution, setting the door body 40 can avoid isolating the battery compartment 21 from the outside world to protect the safety of the power battery in the battery compartment 21.
[0041] In an embodiment of the present application, a door lock assembly 41 for locking the door body 40 to the frame body 10 is provided on the door body 40.
[0042] Adopting the above technical solution, the door lock assembly 41 can effectively lock the door body 40 to the frame body 10, preventing the batteries or other components inside the battery compartment 21 from being damaged or displaced due to vibration or impact during vehicle driving. At the same time, it prevents unauthorized opening of the battery compartment 21 by external personnel, ensuring the safety of the battery and equipment. The door lock assembly 41 can be designed in the form of a key lock or an electronic lock, increasing the anti-theft performance and preventing the battery or other valuable components from being stolen. The door lock assembly 41 is usually designed with an easy-to-operate structure, such as a quick locking and unlocking mechanism, enabling users to conveniently open or close the battery compartment 21 and simplifying the operations of daily maintenance and battery replacement.
[0043] In an embodiment of the present application, a first windproof bracket for inserting the first end of the windproof hook is further provided on the frame body 10, and a second windproof bracket for inserting the second end of the windproof hook is provided on the door body 40.
[0044] Specifically, a first windproof bracket is provided on the frame body 10 for inserting the first end of the windproof hook. A second windproof bracket is provided on the door body 40 for inserting the second end of the windproof hook. The windproof hook is made of stainless steel or high-strength alloy to ensure its stability in strong winds. One end of the windproof hook is inserted into the first windproof bracket, and the other end is inserted into the second windproof bracket.
[0045] Adopting the above technical solution, the windproof hook firmly connects the frame body 10 and the door body 40 through the first windproof bracket and the second windproof bracket, capable of effectively resisting strong winds and preventing the door body from being blown open or damaged. The design of the windproof hook makes installation and disassembly simple, facilitating maintenance and repair.
[0046] In an embodiment of the present application, a limiting member 22 is provided at the bottom of the battery compartment 21, which can wrap around the peripheral side of the bottom of the power battery pack to limit the displacement of the power battery pack.
[0047] Adopting the above technical solution, the limiting member 22 can effectively limit the displacement of the power battery pack in the battery compartment 21, ensure the stability of the battery pack during vehicle driving, and reduce the displacement risk caused by vibration or impact. By preventing the displacement of the battery pack, the limiting member 22 can reduce the risk of the battery pack falling off or being damaged in extreme situations (such as collision or sudden braking), and improve the safety of the overall system. The limiting member 22 wraps around the peripheral side of the bottom of the battery pack, which can provide additional mechanical protection to prevent direct damage to the battery pack caused by external impact, thereby extending the service life of the battery pack.
[0048] In an embodiment of the present application, a wire harness routing board is connected to the vehicle frame body 10, and the wire harness axis board is located on the side of the strengthening beam 20 close to the battery compartment 21.
[0049] Specifically, the wire harness routing board can effectively protect the wire harness, prevent the wire harness from being worn or damaged during vehicle operation. The wire harness routing board can help to straighten the wire harness, make the arrangement of the wire harness more neat and orderly, simplify the installation process, and reduce the installation time and difficulty. The wire harness routing board can fix the wire harness in a specific position, avoid the wire harness from loosening or falling off due to vibration or collision during driving, and improve the safety of the vehicle.
[0050] In an embodiment of the present application, when the power battery is a lithium battery, a counterweight 60 is provided on the side of the vehicle frame body 10 away from the vehicle head.
[0051] Adopting the above technical solution, lithium batteries are usually relatively light. Setting the counterweight 60 can balance the weight distribution of the vehicle body, avoid uneven front and rear weights of the vehicle, and improve driving stability. By reasonably configuring the vehicle body weight, the handling performance of the vehicle will be improved. Especially when turning or changing lanes, the response of the vehicle will be more sensitive and stable.
[0052] In an embodiment of the present application, the door body 40 is further provided with a proximity switch 50, and the proximity switch 50 is located on one side of the access opening of the battery compartment 21.
[0053] With the above technical solution, the proximity switch 50 can automatically sense the approach of a person or an object, thereby automatically triggering the switch to act. This enables the user to access the battery without manual operation, improving convenience. Since the proximity switch 50 is a non-contact sensing device, mechanical wear is reduced, thus extending the service life of the device. The proximity switch 50 can effectively prevent misoperation. For example, when the battery compartment 21 is not fully closed, the proximity switch 50 can issue an alarm prompt to prevent the battery compartment 21 from accidentally opening during driving.
[0054] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
