[0029] The working principle and beneficial effects of this utility model are as follows:

[0030] This utility model provides a tracked power-assisted forklift, comprising: a frame including a load-bearing section, one end of which is provided with a handrail; a tracked walking mechanism symmetrically arranged below the end away from the handrail; and forks positioned above the end away from the handrail, and spaced apart along the width of the load-bearing section; the load-bearing section and the forks form a loading area. This utility model aims to achieve power-assisted drive, better terrain adaptability, and improved maneuverability for the forklift. Specifically, by utilizing a tracked walking mechanism, the forklift has better grip in the field, enabling it to better adapt to different terrains; it reduces the likelihood of slipping, getting stuck in mud, or sinking into pits when using a traditional wheeled walking mechanism in soft soil, uneven terrain, muddy wetlands, or other similar environments. The forks are spaced apart and movable along the width of the load-bearing frame of the load-bearing section, allowing for adjustment of the fork spacing during use to expand or reduce the loading area of ​​the forklift, thus enabling it to accommodate goods of different sizes.

[0031] More specifically, compared with the prior art, the present invention has the following beneficial effects:

[0032] 1. This utility model, by setting up a walking mechanism consisting of tracks, drive wheels, road wheels, and guide wheels, eliminates the need for components such as differentials, reducers, and drive shafts, which are indispensable in traditional bridge-type transmission structures, effectively improving the vehicle's transmission efficiency and reliability. Simultaneously, the tracks have a large contact area with the ground, reducing slippage and allowing for better adaptation to complex terrains such as soft ground and muddy roads. They are less prone to getting stuck, effectively improving the loader's obstacle-crossing ability, passability, and adaptability to complex terrain. The road wheels bear the vehicle and its weight, increasing the loader's load-bearing capacity while ensuring stable operation; the guide wheels ensure the tracks operate normally, preventing deviation and improving vehicle stability and handling.

[0033] 2. This invention employs a hub motor for direct independent drive, effectively reducing the number and size of vehicle parts, resulting in a simpler and more compact vehicle structure. This not only lowers manufacturing costs but also allows operators to precisely control the rotational speed of the two drive wheels, leading to a smaller turning radius and more agile steering.

[0034] 3. The walking mechanism used in this utility model has four wheels on the ground, so the unbalanced force generated during the driving process will not be applied to the person, and it can be easily operated.

[0035] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention can be realized and obtained by means of the structures particularly pointed out in the written description and the accompanying drawings.

[0055] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0056] Example 1

[0057] Please refer to Figures 1-10 As shown, a tracked power loader includes:

[0058] The frame 10 includes a load-bearing part 101, and a handle 102 is provided at one end of the load-bearing part 101;

[0059] The tracked walking mechanism 30 is symmetrically arranged below the end away from the handrail 102;

[0060] The forks 1013 are positioned above the end away from the handle 102 and are spaced out along the width direction of the support portion 101;

[0061] The load-bearing unit 101 and the forks 1013 form the loading area.

[0062] In this utility model, by using a tracked walking mechanism 30 for movement, the hand loader has better grip when used in the field and can better adapt to different terrains; it reduces the chance of slipping, getting stuck in mud or pits when the traditional wheeled walking mechanism encounters soft soil, bumpy mountains, muddy wetlands or other environments in the field.

[0063] The forks 1013 are spaced apart and movable in the width direction of the support frame 1011 of the load-bearing part 101. During use, the spacing of the forks 1013 can be adjusted according to the load conditions to expand or reduce the load area of ​​the forklift, thereby enabling it to adapt to the transport of goods of different sizes.

[0064] More specifically, the frame 10 includes a support section 101 for carrying loads and a handrail section 102 connected to the support section 101 for easy operation by the operator.

[0065] The connecting frame 20 is used to support the frame 10 and is located at the lower part of the frame 10. The bearing part 101 is vertically rotatably connected to the connecting frame 20 at the end away from the handrail part 102. The frame 10 rotates vertically relative to the connecting frame 20 to facilitate loading and unloading of goods.

[0066] Two traveling mechanisms 30 are symmetrically arranged on both sides of the connecting frame 20 for driving the frame 10 and the connecting frame 20 to move;

[0067] The traveling mechanism 30 includes a track 301, a drive wheel 302 for driving the track 301, a road wheel 303 for supporting the frame 10, the connecting frame 20 and its weight, and a guide wheel 304 for guiding the track 301. The track 301 is wrapped around the outside of the drive wheel 302, the road wheel 303 and the guide wheel 304, and the track 301 wrapped around the lower part of the drive wheel 302 and the road wheel 303 is in contact with the ground.

[0068] Example 2

[0069] Please refer to Figures 1-10 As shown, in this embodiment, the tracked walking mechanism 30 includes:

[0070] The track 301 and the drive assembly are wrapped around the outside of the drive assembly, and the drive assembly is mounted on the frame 10 via the side plate 201.

[0071] The drive assembly includes: a drive wheel 302, a load wheel 303, and a guide wheel 304, which are sequentially spaced on the side plate 201;

[0072] The drive wheel 302, the load wheel 303, and the guide wheel 304 are connected to the side plate 201 via the first wheel axle 3021, the second wheel axle 3031, and the third wheel axle 3041, respectively.

[0073] The side panels 201 are in two sets, and the two sets of side panels 201 are connected by a connecting rod 203, which is connected to the frame 10.

[0074] Specifically, in this embodiment, by setting up a walking mechanism 30 consisting of tracks 301, drive wheels 302, road wheels 303, and guide wheels 304, compared to traditional wheels, the drive wheels 302 drive the tracks 301 to move the hand loader. This eliminates the need for components such as differentials, reducers, and drive shafts, which are essential in traditional bridge-type transmission structures, thus improving the vehicle's transmission efficiency and reliability. At the same time, the tracks 301 have a large contact area with the ground, providing strong grip and reducing slippage. This allows for better adaptation to complex terrains such as soft ground and muddy roads, reducing the likelihood of getting stuck and effectively improving the hand loader's obstacle-crossing ability, passability, and adaptability to complex terrain.

[0075] In addition, by setting the road wheels 303 to bear the weight of the vehicle and the cargo, the load-bearing capacity of the hand loader is improved while ensuring the smooth operation of the vehicle; the guide wheels 304 ensure the normal operation of the tracks 301, prevent deviation, and improve the vehicle's driving stability and handling.

[0076] It should be noted that the track 301 in this embodiment is made of rubber, such as natural rubber, styrene-butadiene rubber, or neoprene rubber. The excellent flexibility of rubber allows the track 301 to better adapt to various complex terrains. When encountering uneven ground, the rubber track 301 can bend flexibly and conform closely to the ground, effectively reducing vehicle bumps and ensuring the stability of the hand-operated excavator. When traversing potholes or crossing small stones, the rubber track 301 can bend and deform, preventing damage to the track 301 due to excessive localized stress and ensuring smooth vehicle passage. The elasticity of rubber provides excellent shock absorption, reducing vibration and noise caused by friction and collision between the track 301 and the ground during vehicle operation.

[0077] Meanwhile, compared to the metal track 301, the rubber track 301 is lighter, reducing the overall weight of the vehicle, decreasing energy consumption, and improving the vehicle's handling agility. Rubber has a certain degree of wear resistance, and after special formulation and processing, it can meet the requirements for long-term use, reducing maintenance costs.

[0078] Example 3

[0079] Please refer to Figure 5 , Figure 6 and Figure 7 As shown, in this embodiment, the drive wheel 302 includes:

[0080] The hub shell 3022 is concentrically fitted outside the first wheel axle 3021. The circumference of the hub shell 3022 is evenly distributed with grooves 30221, and the width of the grooves 30221 is greater than the length of the track teeth.

[0081] End caps 3023 are disposed on both sides of the hub housing 3022;

[0082] The column 3024 is arranged in a circular array within the groove 30221 of the hub housing 3022. The central axis of the column 3024 is parallel to the central axis of the hub housing 3022. Adjacent columns 3024 form a tooth groove that meshes with the track 301.

[0083] Brake assembly 3025 is symmetrically fixed inside end cover 3023 and connected to brake handle 30253 of handle 102. Specifically, it is symmetrically fixed outside connecting bracket side plate 201 and inside end cover 3023 to achieve braking of hub motor.

[0084] The axles of the first wheel axle 3021, the second wheel axle 3031, and the third wheel axle 3041 form an inverted triangle; the lower part of the circumferential outer wall of the drive wheel 302 and the load wheel 303 is on the same horizontal plane; the upper part of the circumferential outer wall of the drive wheel 302 and the guide wheel 304 is on the same horizontal plane.

[0085] In this embodiment, the drive wheel 302 is directly driven by a hub motor, eliminating the differential, reducer, drive shaft and other components in the traditional bridge transmission structure. This reduces the number of parts and makes the structure simpler and more compact, which not only reduces manufacturing and maintenance costs, but also improves the vehicle's passability and reliability.

[0086] This invention employs a hub motor for independent direct drive, which not only reduces the manufacturing and assembly costs of the vehicle but also provides more space for the rational layout of other components, thereby improving the vehicle's space utilization rate.

[0087] Meanwhile, this embodiment uses two motors for independent direct drive, enabling operators to precisely control the speed and direction of each drive wheel, thus achieving zero-radius turning.

[0088] It should be noted that the working principle of the hub motor is existing technology and will not be elaborated here.

[0089] Example 4

[0090] Please refer to Figure 1 , Figure 5 , Figure 6 and Figure 10 As shown, in this embodiment, the brake assembly 3025 includes:

[0091] Brake disc 30251 is mounted on end cover 3023 on the side near side plate 201 and rotates synchronously with end cover 3023;

[0092] Brake caliper 30252 is mounted on side plate 201 and is used to brake brake disc 30251;

[0093] The brake handle 30253 is connected to the brake caliper 30252, and brakes the brake disc 30251 through the brake caliper.

[0094] Specifically, in this embodiment, the brake assembly 3025 includes: a brake disc 30251, fixed on an end cap 3023 near the side plate 201, rotating synchronously with the end cap 3023; a brake caliper 30252, fixed on the side plate 201, remaining stationary; and a brake handle 30253, used to control the brake caliper 30252 to brake the brake disc 30251, with the brake handle 30253 located on the left handle 1022 of the handrail.

[0095] It should be noted that in this embodiment, the brake caliper 30252 is connected to the brake handle 30253 via an oil pipe, forming a hydraulic braking system. When the hand loader brakes, the brake caliper 30252, under the coordinated action of the brake handle, oil pipe, electronic switch, and other braking device components, tightly clamps the brake disc 30251, thereby achieving deceleration or stopping of the vehicle.

[0096] Obviously, the braking method of the aforementioned brake assembly 3025 can also be achieved using other structural methods, such as electromagnetic brake braking.

[0097] Example 5

[0098] Please refer to Figure 1 , Figure 2 , Figure 8 As shown, in this embodiment, the drive wheel 302 is a hub motor, the electrical control terminal of the hub motor is electrically connected to the motor controller 60, and the motor controller 60 is electrically connected to the switch assembly 70 and the control board.

[0099] The control board is electrically connected to the power supply. Both the power supply and the control board are located in the control box 40, which is mounted on the vehicle frame via the mounting bracket 50.

[0100] Mounting bracket 50 includes: mounting frame 501, which is disposed at the lower part of support frame 1011;

[0101] The first mounting plate 502 is located on the upper part of the mounting frame 501 and close to the handrail 102; there is a first mounting space between the first mounting plate 502 and the support frame 1011, and the control box 40 is located in the first mounting space and is movably mounted on the first mounting plate 502.

[0102] More specifically, to facilitate power supply, this embodiment of the tracked power-assisted forklift also includes a control box 40 and a mounting bracket 50 for housing the control box 40. The control box 40 houses components such as a battery, a power switch, and overcurrent protection devices. In this embodiment, the battery is preferably a high-energy-density lithium battery, which has the advantage of a longer driving range in low-temperature environments.

[0103] It should be noted that, in this embodiment, the mounting frame 50 includes a mounting frame 501 fixed to the lower part of the support frame 1011 and a first mounting plate 502 disposed on the upper part of the mounting frame 501. The first mounting plate 502 and the support frame 1011 have a first mounting space. The control box 40 is located in the first mounting space and is movably mounted on the first mounting plate 502.

[0104] The specific mounting frame 50 is formed by welding seamless steel pipes in a horizontal and vertical manner to form a mounting frame 501 fixed at the lower part of the support frame 1011. The first mounting plate 502 is fixed to the upper part of the mounting frame 501 by welding. The control box 40 is fixed to the first mounting plate 502 with screws.

[0105] In this embodiment, the control box 40 is located at one end near the handrail 102. In this way, the weight of the control box 40 can be used to counterweight the goods, thereby reducing the need for the operator to apply a counterweight force to the handrail 102 to overcome the weight of the goods. It also facilitates the operation of the electrical switches.

[0106] Example 6

[0107] Please refer to Figures 1-10 As shown, in this embodiment, the frame 10 is provided with crossbeams at intervals, and the crossbeams are connected by a support frame 1011.

[0108] The forks 1013 are provided in at least two sets, forming an L-shape with the frame 10, and are symmetrically and movably mounted on the crossbeam below the frame 10 with the support frame 1011 as the center.

[0109] Furthermore, in this embodiment, the support frame 1011 is movably placed on the connecting frame 20, and the support seat 1012 is disposed at the end of the support frame 1011 away from the handrail 102. The support frame 1011 is vertically rotated around the support seat 1012 and is used for loading and unloading goods.

[0110] Among them, the bearing seat 1012 is rotatably sleeved and extends to the outside of the third wheel axle 3041 on the side of the side plate 201 away from the guide wheel 304.

[0111] Specifically, the bearing unit 101 includes a bearing frame 1011 movably mounted on the support base 204. A bearing seat 1012 is fixedly provided at one end of the bearing frame 1011 away from the handrail 102.

A fork 1013 is provided at one end of the bearing frame 1011 away from the handrail 102 along the width direction of the bearing frame 1011. The fork 1013 is used for scooping and preventing slippage.

[0112] It should be noted that, in order to improve the overall structural integrity of the support frame 1011, the support frame 1011 in this embodiment is welded from seamless steel pipes. The aforementioned support frame 1011 comprises several seamless steel pipes, which are combined and formed by connecting them in a transverse, longitudinal, and bending manner. The function of the support frame 1011 in this embodiment is to provide a platform for supporting objects and has a certain load-bearing capacity. The specific structure of the support frame 1011 is not limited.

[0113] In this embodiment, by setting forks 1013, the support frame 1011 can rotate vertically around the support base 1012, and the angle of the forks 1013 can be adjusted to facilitate loading and unloading of goods by the operator. At the same time, by adjusting the distance between the forks 1013, the forks 1013 can adapt to the width of different goods, improving the applicability and flexibility of the forklift.

[0114] It should be noted that, in this example, the fork 1013 includes a horizontal part for scooping goods and a vertical part for hanging on the support frame 1011, and its shape is L-shaped. The fork 1013 is forged from low-alloy steel.

[0115] Example 7

[0116] Please refer to Figure 1 and Figure 10 As shown, in this embodiment, the tracked power loader also includes an electrical control system and a second mounting space formed between the second mounting plate 205 disposed inside the two side plates 201 and the support frame 1011. The electrical control system includes a motor controller 60 located in the second mounting space and fixed on the second mounting plate 205 and a switch assembly 70 connected thereto. The switch assembly 70 is used to control the movement of the tracked power loader.

[0117] The switch assembly 70 is located on the handrail 102. The switch assembly 70 includes a power switch for controlling the vehicle's power supply, forward and reverse buttons for controlling the vehicle's direction of travel, a thumb throttle for manually controlling the driving speed, a switch for switching between manual and automatic modes, and a speed control switch for switching between low, medium, and high speeds. In automatic mode, it offers high, medium, and low speeds to meet the needs of different application scenarios and terrain environments.

[0118] It should be noted that in this embodiment, the handle 102 includes a left handle 1022 disposed on the left side of the support 101 and a right handle 1021 disposed on the right side of the support 101. The power switch, forward / reverse buttons, and manual mode speed control switch are located on the right handle 1021; the manual / automatic mode switch, three-speed conversion switch, and brake lever 30253 are located on the left handle 1022. The working principle and connection method of the switch assembly 70 are prior art and will not be described further here.

[0119] Obviously, the aforementioned switch assembly 70 can be combined in various ways according to operational needs, so as to facilitate operator operation and improve the flexibility of the hand loader.

[0120] The tracked power loader provided in this application has a simple structure, low manufacturing and maintenance costs, and good terrain adaptability, passability, and maneuverability.

[0122] Please refer to Figure 3 and Figure 4 As shown, in this embodiment, it further includes: a connecting frame 20, which includes:

[0123] Two side plates 201, drive wheel 302, load wheel 303 and guide wheel 304 are connected to the outside of side plate 201 through first wheel axle 3021, second wheel axle 3031 and third wheel axle 3041 respectively. The central axes of the first wheel axle 3021, second wheel axle 3031 and third wheel axle 3041 are all perpendicular to side plate 201.

[0125] The connecting rod 203 is fixed in the holes of the two connecting seats 202, and the central axis of the connecting rod 203 coincides with the central axis of the connecting seat 202 and the central axis of the first wheel shaft 3021.

[0126] Two support seats 204 are symmetrically arranged on the upper part of the connecting rod 203. The top surface of the support seat 204 forms an angle of 18° with the horizontal plane. The support seat 204 is used to support the bearing part 101.

[0127] In this embodiment, a connecting frame 20 is used to connect the traveling mechanism 30 and provide an installation and support platform for the frame 10. Specifically, the two side plates 201 provide installation positions for the drive wheel 302, load-bearing wheel 303, and guide wheel 304 of the traveling mechanism 30, ensuring the stability of the rotation of each wheel. The side plates 201 provide a vertical rotation base for the frame 10, making it easy to load and unload goods. The support seat 204 provides support for the frame 10. The frame 10 is placed on the support seat 204, so that the operator does not bear the gravitational torque during vehicle movement, resulting in good maneuverability and stability.
