Description

Technical Field

[0001] This utility model relates to the field of trolley technology, and in particular to an electric-assisted unicycle handcart. Background Technology

[0002] Electric-assisted unicycle handcarts, with their flexibility, convenience, labor-saving, and high efficiency, are widely used in warehousing, material handling, and logistics distribution, becoming a key tool for reducing manual labor intensity and improving handling efficiency. The handlebars, as the core component for user control, directly impact operating comfort and user experience with their adaptability and ease of adjustment, which is especially important for users engaged in long-term operations.

[0003] Existing electric-assisted unicycles have significant technical limitations in their design, which restricts the improvement of user experience. The handle height of traditional unicycles is mostly fixed and cannot be adjusted according to the user's height. This forces users of different heights to bend over or stand on tiptoe to operate the unicycle, which can easily cause fatigue in the waist and shoulders with long-term use, significantly reducing operating comfort and even affecting work efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an electric-assisted unicycle handcart, which solves the technical problem that the handle height of existing unicycle handcarts is mostly fixed and cannot be adjusted according to the user's height. This causes users with different heights to have to bend over or stand on tiptoe to operate the cart, which can easily lead to lower back and shoulder fatigue and significantly reduce the comfort of operation after long-term use.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An electric-assisted unicycle includes an electric cart body, which includes a frame. A placement platform is mounted on the upper surface of the frame. Two sets of slots are provided on one side of the frame, and an adjustment component that can be adjusted according to the user's height is rotatably connected inside the two sets of slots. A sliding groove is provided on the front of the frame, and a positioning component is slidably connected inside the sliding groove. Multiple sets of grooves are provided on the upper surface of the placement platform, and a limit component is rotatably connected inside the multiple sets of grooves. The placement platform includes a first folding plate and a second folding plate. The first folding plate is detachably mounted on the upper surface of the frame, and the second folding plate is detachably mounted on the upper surface of the adjustment component.

[0007] Preferably, the adjustment assembly includes two sets of mounting brackets, which are rotatably connected to two sets of slots on the frame. A positioning plate is installed on one side of the frame, and a motor is installed on the front of the positioning plate. A gear two is installed on the outer end of the output shaft of the motor. The outer teeth of the gear two are meshed with a gear one. A rotating rod is installed on the inner wall of the gear one. The front and rear ends of the rotating rod pass through the frame and are connected to the interior of the two sets of mounting brackets. The folding plate two is detachably installed on the upper surface of the two sets of mounting brackets.

[0008] Preferably, the positioning component includes a limiting rod, which is slidably connected inside the slide groove of the frame, the second gear is located on the moving path of the limiting rod, and a push plate is installed at the front end of the limiting rod.

[0009] Preferably, an annular magnetic block is installed at the outer end of the limiting rod, and the back of the annular magnetic block is attracted to the front of the vehicle frame.

[0010] Preferably, a limit bracket is installed on the front of the vehicle frame, and the rear end of the limit rod is slidably connected inside the limit bracket.

[0011] Preferably, a handlebar is installed on the top of the inner wall of the mounting bracket, and a controller body is installed on the side of the front set of handlebars away from the adjacent set of mounting brackets. The controller body and the control terminal of the motor are electrically connected.

[0012] Preferably, the limiting component includes multiple sets of rotating blocks, the upper surface of the first folding plate has multiple sets of grooves, the rotating blocks are rotatably connected inside the grooves of the first folding plate, and a connecting sleeve is installed on the upper surface of the rotating blocks.

[0013] Preferably, two sets of limiting brackets are installed on the upper surface of the second folding plate, and the second limiting bracket is installed on the side of the vehicle frame away from the adjustment component.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The motor drives gear two to rotate gear one and the rotating rod. The front and rear ends of the rotating rod are fixed to the adjacent sides of the two sets of mounting brackets. When the rotating rod rotates, it drives the two sets of mounting brackets to rotate inside the two sets of slots on the frame. This allows the operator to adjust the height of the two sets of handlebars according to their own standing height, making it easier for users of different heights to move the device and improving the comfort of the user when operating it. 2. The folding plate two is detached and installed on the upper end of the two sets of mounting brackets. When the two sets of mounting brackets rotate, the folding plate two drives the folding plate two to bend on one side of the folding plate one. This prevents the folding plate two from interfering with the normal adjustment and movement of the handlebars when it is installed on the upper end of the adjustment component.

[0016] Second, by pushing the push plate, the limiting rod slides inside the groove of the frame, and the rear end of the limiting rod is inserted into the inside of the second gear. This restricts the rotation position of the second gear by the positioning component, preventing the second gear from rotating when idle and causing the adjustment component to rotate on one side of the frame. This improves the stability of the adjustment component during use. Attached Figure Description

[0024] This application provides an electric-assisted unicycle, which effectively solves the technical problem that the handle height of existing unicycles is mostly fixed and cannot be adjusted according to the user's height. This causes users with different heights to have to bend over or stand on tiptoe to adapt when operating the unicycle, which can easily lead to waist and shoulder fatigue and significantly reduce the comfort of operation after long-term use.

[0025] Example

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the technical solution in this application embodiment effectively solves the problem that the handle height of existing unicycles is mostly fixed, and cannot be adjusted according to the user's height. This causes users with large differences in height to have to bend over or stand on tiptoe to adapt when operating the unicycle, which can easily lead to fatigue in the waist and shoulders with long-term use, and significantly reduce the comfort of operation. The overall idea is as follows:

[0027] To address the problems existing in the prior art, this utility model provides an electric-assisted unicycle handcart, including a cart body 1, a frame 2, a placement platform 12 mounted on the upper surface of the frame 2, two sets of slots on one side of the frame 2, and an adjustment component 3 rotatably connected inside the two sets of slots to adjust according to the user's height, an adjustment groove on the front of the frame 2, and a positioning component 9 slidably connected inside the adjustment groove, and multiple sets of grooves on the upper surface of the placement platform 12, with a limit component 7 rotatably connected inside the multiple sets of grooves of the placement platform 12. The placement platform 12 includes... Folding plate 1201 and folding plate 2202 are installed on the upper surface of the frame 2, and folding plate 1201 is installed on the upper surface of the adjustment assembly 3. Specifically, by activating the adjustment assembly 3, it is driven to rotate within the two sets of slots on the frame 2. When the two sets of adjustment assemblies 3 rotate, they adjust the height of one end of themselves, so that the staff can adjust the height position of one side of the adjustment assembly 3 according to their own standing height. This makes it easier for users of different heights to push the device to move, thereby improving the comfort of the user when operating the device.

[0028] The adjustment assembly 3 includes two sets of mounting brackets 301, which are rotatably connected to two sets of slots in the frame 2. A positioning plate 304 is installed on one side of the frame 2. A motor 305 is installed on the front of the positioning plate 304. A gear 2 306 is installed on the outer end of the output shaft of the motor 305. The outer teeth of the gear 2 306 are meshed with a gear 1 303. A rotating rod 302 is installed on the inner wall of the gear 1 303. The front and rear ends of the rotating rod 302 pass through the frame 2 and are connected to the inside of the two sets of mounting brackets 301. The folding plate 2 1202 is detached and installed on the upper surface of the two sets of mounting brackets 301.

[0029] Specifically, the starting motor 305 drives the gear 2 306 to rotate the gear 1 303 and the rotating rod 302. The front and rear ends of the rotating rod 302 are fixedly installed on the adjacent sides of the two sets of mounting brackets 301, so that when the rotating rod 302 rotates, it drives the two sets of mounting brackets 301 to rotate inside the two sets of slots in the frame 2. This allows the operator to adjust the height of the two sets of handlebars 4 according to their own standing height, making it easier for users of different heights to push the device and improving the comfort of the user when operating the device. The folding plate 2 1202 is detached and installed on the upper end of the two sets of mounting brackets 301. When the two sets of mounting brackets 301 rotate, they drive the folding plate 2 1202 to bend on one side of the folding plate 1201, thus preventing the folding plate 2 1202 from affecting the normal adjustment and movement height of the handlebars 4 when it is installed on the upper end of the adjustment component 3.

[0030] The positioning component 9 includes a limiting rod 902, which is slidably connected inside the slide groove of the frame 2. The gear 306 is located on the movement path of the limiting rod 902, and a push plate 901 is installed at the front end of the limiting rod 902. Specifically, by pushing the push plate 901, the limiting rod 902 is driven to slide inside the slide groove of the frame 2, and the rear end of the limiting rod 902 is inserted into the inside of the gear 306. This allows the positioning component 9 to restrict the rotation position of the gear 306, preventing the gear 306 from rotating when idle, which would cause the adjustment component 3 to rotate on one side of the frame 2. Therefore, the stability of the adjustment component 3 during use is improved.

[0031] An annular magnetic block 10 is installed on the outer end of the limiting rod 902, and the back of the annular magnetic block 10 is attached to the front of the frame 2. Specifically, by pushing the push plate 901, the back of the annular magnetic block 10 is attached to the front of the frame 2, so that the annular magnetic block 10 restricts the movement of the limiting rod 902 inside the slide groove of the frame 2, and prevents the positioning component 9 from sliding inside the slide groove of the frame 2 during use, thereby improving the stability of the positioning component 9 during use.

[0032] A limiting frame 11 is installed on the front of the frame 2, and the rear end of the limiting rod 902 is slidably connected inside the limiting frame 11. Specifically, by slidably connecting the rear end of the limiting rod 902 inside the limiting frame 11, the limiting frame 11 restricts the sliding path of the rear end of the limiting rod 902 and supports the rear end of the limiting rod 902, thus preventing the limiting rod 902 from tilting during use and improving the stability of the positioning component 9 during use.

[0033] A handlebar 4 is installed on the top of the inner wall of the mounting bracket 301. A controller body 5 is installed on the side of the front set of handlebars 4 away from the adjacent set of mounting brackets 301. The controller body 5 and the control terminal of the motor 305 are electrically connected. Specifically, the motor 305 is started by operating the controller body 5, so that the operator does not need to manually start the motor 305 when adjusting the height of the adjustment component 3. This reduces the amount of labor required for the operator to adjust the height of the adjustment component 3, thus improving the practicality of the device in use.

[0034] The limiting component 7 includes multiple sets of rotating blocks 701. Multiple grooves are formed on the upper surface of the folding plate 1201. The rotating blocks 701 are rotatably connected to the grooves of the folding plate 1201. Connecting sleeves 702 are installed on the upper surface of the rotating blocks 701. Specifically, by pulling the rope, the rope passes through the multiple connecting sleeves 702 and is tightly taut over the goods placed on the upper end of the frame 2. This allows the limiting component 7, in conjunction with the rope, to restrict the movement of the goods placed on the upper end of the electric cart body 1, preventing the goods from moving during transport. By pushing the connecting sleeves 702, the rotating blocks 701 rotate within the grooves of the folding plate 1201, allowing the binding pattern of the rope on the upper end of the electric cart body 1 to be adjusted according to the placement of the goods, thereby improving the binding effect of the limiting component 7 with the rope.

[0035] Two sets of limiting frames 6 are installed on the upper surface of the folding plate 2 1202, and a limiting frame 8 is installed on the side of the frame 2 away from the adjustment component 3. Specifically, by installing the two sets of limiting frames 6 and the limiting frame 8 on the front and rear sides of the goods on the upper end of the frame 2 respectively, the two sets of limiting frames 6 and the limiting frame 8 restrict the movement path of the goods on the upper end of the frame 2, so as to prevent the goods accumulated on the upper end of the electric cart body 1 from rolling and falling to the ground when the staff does not install the binding rope.

[0036] Working principle:

[0037] The first step involves starting the motor 305 to drive the gear 2 306, which in turn drives the gear 1 303 and the rotating rod 302 to rotate. The front and rear ends of the rotating rod 302 are then fixedly installed on the adjacent sides of the two sets of mounting brackets 301. When the rotating rod 302 rotates, it drives the two sets of mounting brackets 301 to rotate inside the two sets of slots on the frame 2. This allows the staff to adjust the height of the two sets of handlebars 4 according to their own standing height, making it easier for users of different heights to push the device to move.

[0038] The second step involves pushing the push plate 901 to drive the limiting rod 902 to slide inside the groove of the frame 2, inserting the rear end of the limiting rod 902 into the inside of the gear 2 306, so that the positioning component 9 restricts the rotation position of the gear 2 306, preventing the gear 2 306 from rotating when idle, which would cause the adjustment component 3 to rotate on one side of the frame 2, thus improving the stability of the adjustment component 3 during use.

[0039] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
