Description

Technical Field

[0001] The invention relates to a loader chassis, in particular to a small electric loader chassis which is convenient for disassembling a battery pack, and belongs to the technical field of loader chassis. Background Art

[0002] A small electric loader is a type of loader with compact size and light weight. It has significant advantages in environments where space is limited or flexible operation is required. Its compact design is more suitable for lightweight loading and handling work, such as construction sites, landscaping, agricultural production and other scenarios. The small electric loader is powered by electricity and has the advantages of environmental protection, low noise and easy maintenance. Since it does not use fuel, it does not emit harmful gases and is environmentally friendly. At the same time, the electric drive has low operating noise and will not cause noise pollution to users or the surrounding environment. The small electric loader has basic loading, unloading, transportation and other functions, which can meet general material handling needs. Some advanced electric loaders are also equipped with intelligent control systems to achieve precise operation and efficient work.

[0003] Since electric loaders are battery-driven and do not use diesel, there is a great demand for batteries. Existing ways of mounting batteries on loaders are mostly to build a battery compartment on the loader chassis and use a frame-type battery compartment to install the battery pack. However, when the battery pack needs to be disassembled, it is also necessary to remove the outer shell of one side of the loader and then remove the batteries one by one. It is relatively convenient to disassemble the batteries on the outside, but it is more difficult to disassemble the batteries on the inside, especially for small electric loaders. The battery compartment has a limited height, and manual disassembly and removal is very inconvenient.

[0004] In addition, in order to ensure the stable operation of the battery pack and the temperature will not be too high during operation, a cooling structure is usually installed on the outside of the battery compartment. To ensure the cooling effect, some electric loaders use water cooling to cool the battery compartment. However, the current water cooling structure has a relatively single function. The water vapor generated by heat exchange is either condensed and returned or directly discharged and cannot be effectively utilized, resulting in energy waste. At the same time, considering that the connection between the current loader shaft and the positioning structure has lubricating oil sludge after long-term use, it needs to be cleaned regularly to ensure the lubrication effect. Summary of the invention

[0005] The purpose of the present invention is to provide a small electric loader chassis that is easy to disassemble the battery pack in order to solve the above-mentioned problem. The battery is loaded and unloaded with a rotating structure. The loading and unloading of the battery pack is convenient and quick. The battery is cooled by a water cooling component. The transmission rod of the transmission system is automatically positioned by a self-lubricating shaft positioning component. The water cooling component can spray high-temperature water vapor to the side of the connection between the transmission rod and the self-lubricating shaft positioning component through a steam nozzle, and the sludge is flushed with high temperature and water to separate the sludge from the transmission rod, thereby effectively preventing the sludge from accumulating and affecting the lubrication effect.

In actual use, the sealing cover is opened to expose the battery insertion slot, and then the rotating battery mounting frame is controlled to rotate to align the battery mounting slot with the battery insertion slot. At this time, the battery can be installed in the battery mounting slot. After installation, the rotating battery mounting frame is rotated again to transfer the battery into the internal space of the battery storage box. The rotating battery mounting frame is continuously rotated until another empty battery mounting slot is aligned with the battery insertion slot, and then the battery is installed. The above operation is repeated until batteries are loaded into each battery mounting slot, and the installation of the battery pack is completed. After the battery installation is completed, the sealing cover is reinstalled to seal the battery insertion slot. When disassembling the battery pack, the battery can be taken out by simply performing the reverse operation steps.

[0007] The outside of the battery storage box is wrapped with a heat-absorbing jacket, and a water-cooling component that can form a circulating water path in the heat-absorbing jacket is fixedly installed in the chassis assembly.

When the battery is rotated to one side of the battery insertion slot, the spring sheet can push the battery out into the battery insertion slot. When the battery needs to be removed, it is only necessary to remove the sealing cover, and then align each battery mounting slot with the battery insertion slot in turn. When the battery moves to the battery insertion slot along with the battery mounting slot, the battery is freed from the restriction of the cylindrical case, and the spring sheet can pop the battery outward, so that there is no need to manually buckle out the battery, and disassembly is more convenient.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-Figure 9 As shown, a small electric loader chassis that is easy to remove the battery pack includes a chassis assembly 1 and two side mounting plates 3 arranged on the front and rear sides of the chassis assembly 1. The side mounting plates 3 are provided with a transmission rod through-slot 2 for the wheel hub transmission system to penetrate. The side mounting plates 3 are the basic structure of the electric loader chassis. When in use, the basic components of the loader such as the transmission system and the braking system can be installed on the chassis assembly 1.

[0032] A battery storage box 4 is fixedly arranged between the two side mounting plates 3, and a rotating battery mounting frame 5 is arranged in the battery storage box 4. A plurality of battery mounting slots 503 are arranged in a circular array in the rotating battery mounting frame 5. The battery storage box 4 is provided with a battery insertion slot 403 that penetrates inside and outside. When the rotating battery mounting frame 5 rotates, the relative position of each battery mounting slot 503 and the battery insertion slot 403 can be adjusted for loading and unloading batteries. A sealing cover 9 is screwed to the battery insertion slot 403. In actual use, the sealing cover 9 is opened to expose the battery insertion slot 403 to the outside, and then the rotating battery mounting frame 5 is controlled to rotate to turn the battery mounting slot 503 to align with the battery insertion slot 403. At this time, the battery can be loaded into the battery mounting slot 503. After loading, the rotating battery mounting frame 5 is rotated again to transfer the battery into the internal space of the battery storage box 4, and the rotating battery mounting frame 5 is continuously rotated until another empty battery mounting slot 503 is aligned with the battery After the battery installation is completed, the sealing cover 9 is reinstalled to seal the battery insertion slot 403. When disassembling the battery pack, it is only necessary to take out the battery in the opposite operation steps. Compared with the existing frame-type battery pack, the present application uses a rotating structure to install the battery. The overall structure is cylindrical and has a large space utilization rate. Especially for small electric loaders, the space is limited. When the traditional frame-type battery rack is used to install the battery, not only the space cannot be effectively utilized, but also the loader shell needs to be removed as a whole during disassembly, which is very inconvenient. The battery loading and unloading port of the present application is equivalent to the battery insertion slot 403 and the battery installation slot 503, and the space occupied is very small. In actual use, only a smaller inspection port needs to be set on the loader shell, and the loading and unloading of the battery pack is very convenient and quick.

[0033] The battery storage box 4 is wrapped with a heat-absorbing jacket 6 on the outside, and a water-cooling component 7 that can form a circulating water path in the heat-absorbing jacket 6 is fixedly installed in the chassis assembly 1. Cooling water is circulated into the heat-absorbing jacket 6 through the water-cooling component 7. The heat-absorbing jacket 6 and the battery storage box 4 are both made of materials with high thermal conductivity, which are used to efficiently absorb the heat generated by the battery to ensure that the battery works stably at a safe temperature. The top of the chassis assembly 1 is symmetrically provided with strip grooves 101 on both sides, and a self-lubricating shaft center positioning component 8 for clamping and fixing the transmission rod of the wheel hub transmission system is installed in the strip groove 101. Through the setting of the self-lubricating shaft center positioning component 8, the transmission After the system's transmission rod is installed, it can be automatically positioned without manual operation, and after positioning, it can self-lubricate on the surface of the transmission rod, further improving the stability of the transmission rod. A steam nozzle 706 is also provided on the water cooling component 7, and the air outlet of the steam nozzle 706 is toward the side of the connection between the transmission rod and the self-lubricating shaft positioning component 8. After a period of use, the connection part between the transmission rod and the self-lubricating shaft positioning component 8 will produce some lubricating sludge. The steam nozzle 706 is set to spray high-temperature water vapor to the sludge, and use high temperature and water to flush the sludge to a certain extent, so that the sludge is separated from the transmission rod, effectively preventing the sludge from accumulating and affecting the lubrication effect.

[0034] Specific as Figure 3 and Figure 4 As shown, the battery storage box 4 includes a cylindrical box body 401, and the inner wall of the cylindrical box body 401 is provided with a plurality of arc-shaped slots 402 for clamping the rotary battery mounting bracket 5 in a circular array. The battery insertion slot 403 is located on the cylindrical box body 401, and the battery is installed through the battery insertion slot 403, and the rotary battery mounting bracket 5 is clamped through the arc-shaped slot 402, so that the rotary battery mounting bracket 5 has a rotating structure, but still requires a certain external force to rotate, and has a stable connection structure under normal conditions to prevent the battery from shaking and separating during use.

[0035] Specific as Figure 3 and Figure 5As shown, the rotatable battery mounting rack 5 includes a rotatable base 501 and arcuate ridges 505 arranged in a circular array on the outer side of the rotatable base 501. The rotatable base 501 is mounted in the cylindrical housing 401 through a rotating shaft 502. The arcuate ridges 505 are inserted into the arcuate slots 402. The arcuate ridges 505 are made of elastic material. The arcuate ridges 505 can be stably clamped by the arcuate slots 402 without being acted upon by external forces, thereby preventing deflection between the rotatable battery mounting rack 5 and the cylindrical housing 401, thereby ensuring the stability of the battery. The arcuate ridges 505 made of elastic material can automatically retract when the rotatable base 501 is rotated under the action of external forces, thereby making the rotatable base 501 a rotatable structure until the arcuate ridges 505 are fixed when docked with another arcuate slot 402, thereby making the rotatable base 501 still have a local fixing effect while rotating, thereby ensuring the stability of battery loading and unloading.

[0036] The battery installation slot 503 is located on the outer side of the rotating base 501, and a spring sheet 504 is fixedly provided on the inner wall of the battery installation slot 503 for applying an outward pushing force from the bottom, so that the battery can be pushed to the inner wall of the cylindrical case 401 by the spring sheet 504 after being installed, so that the battery is tightly connected to the cylindrical case 401 under the squeezing of the spring sheet 504 after being installed, and the structure is relatively stable. When the battery is rotated to one side of the battery insertion slot 403, the spring sheet 504 can push the battery out into the battery insertion slot 403. When the battery needs to be removed, it is only necessary to remove the sealing cover 9, and then align each battery installation slot 503 with the battery insertion slot 403 in turn. When the battery moves to the battery insertion slot 403 as the battery installation slot 503 moves, the battery is freed from the restriction of the cylindrical case 401, and the spring sheet 504 can pop the battery outward, so that there is no need to manually buckle the battery out, and disassembly is more convenient.

[0037] A rotating handle 507 is fixedly provided on one side of the rotating base 501 through an extension rod 506, and an operating port 404 for exposing the rotating handle 507 is opened on one side of the cylindrical box 401. The rotating handle 507 is rotated to drive the rotating base 501 at one end of the extension rod 506 to rotate, thereby controlling the battery position, which is convenient for quick loading and unloading of the battery. The reservation of the operating port 404 makes it easy to manually control when using this application. In specific applications, a driving component can also be installed on the side mounting plate 3 to replace manual rotation adjustment with electric drive.

In actual use, the water outlet pump 702 pumps the water in the water storage tank 701 The water is sucked in and introduced into the heat absorption jacket 6 through the water outlet pipe 703. The heat absorption jacket 6 has a circulation passage. The cold water enters the return pipe 705 after passing through the heat absorption jacket 6 for one circle. Then, the water that has absorbed the heat is sucked in by turning on the water pump 704. The refrigeration parts in the water storage tank 701 are continuously turned on to cool the water, maintaining an efficient and continuous cooling effect, and are used to efficiently absorb the heat generated by the battery to ensure that the battery works stably at a safe temperature. The water outlet pump 702 and the water pump 704 can be turned on at the time of circulation cooling. When the water in the heat absorption jacket 6 needs to be fully recovered, the water pump 704 can be turned on.

[0039] An air pump is also provided on the top of the inner wall of the water tank 701, and a steam nozzle 706 is installed on the water tank 701 and is connected to the air outlet of the air pump, so that the hot water steam in the water tank 701 can be discharged through the steam nozzle 706, and high-temperature water vapor is sprayed to the side of the connection part between the transmission rod and the self-lubricating shaft positioning component 8 through the steam nozzle 706, so as to flush some lubricating sludge generated after use of the connection part between the transmission rod and the self-lubricating shaft positioning component 8, and the sludge is flushed to a certain extent by using high temperature and water, so that the sludge is separated from the transmission rod, thereby effectively preventing the sludge from accumulating and affecting the lubrication effect.

[0040] Specific as Figure 8 and Fig. 9As shown, the self-lubricating axis positioning component 8 includes a double-axis motor 801 fixedly installed at the middle position of the strip groove 101 and a double-axis screw rod 802 rotatably installed on the two side walls of the strip groove 101, the two double-axis screw rods 802 are respectively fixedly connected to the two output shafts of the double-axis motor 801, and the two double-axis screw rods 802 can be driven to rotate by turning on the double-axis motor 801. The self-lubricating axis positioning component 8 also includes a sliding seat 803 slidably arranged in the strip groove 101, and two sliding seats 803 are symmetrically arranged on two opposite threads of the double-axis screw rod 802. An L-shaped connecting rod 804 is fixedly arranged on the top of the sliding seat 803, and one end of the top of the L-shaped connecting rod 804 faces the transmission rod through groove 2.

On both sides, the sliding seats 803 placed in the strip groove 101 can only do lateral movement and cannot rotate. Therefore, when the bidirectional screw rod 802 rotates, the sliding seats 803 can be pushed to move. Since the two sliding seats 803 are respectively located on the screw thread segments in opposite directions, when a single bidirectional screw rod 802 rotates, the two sliding seats 803 connected to it will only approach or move away, thereby causing the two arc-shaped limit plates 805 to approach or move away. In actual application, the two arc-shaped limit plates 805 are first controlled to move away from each other. After the loader transmission system is initially installed, when the transmission rod is between the two arc-shaped limit plates 805, the two arc-shaped limit plates 805 are controlled to approach each other. The extrusion positioning of the transmission rod can be achieved by approaching the two arc-shaped limit plates 805. The graphite roller 806 in the arc-shaped limit plate 805 can also have a self-lubricating effect, thereby making the connection part with the transmission rod smoother and lubricating the surrounding area, which has a high application value.
