Technical Field
[0001] The utility model relates to the field of electric bicycles, in particular to a load-bearing device for electric bicycles which is easy to adjust. Background Art
[0002] In recent years, the electric vehicle industry has developed rapidly, and two-wheeled electric vehicles are favored by consumers for their advantages such as lightness, flexibility, green travel and affordable prices. However, most of the existing two-wheeled electric vehicles are designed and manufactured for carrying people. Since the traffic regulations of many cities stipulate that electric vehicles are not allowed to carry people, some electric vehicles simply do not have back seats in order to save costs or for aesthetics. In addition, most electric vehicles on the market use plastic parts, and are light in weight, and can only carry people and a small amount of light objects.
[0003] Electric vehicles for load-carrying are generally three-wheeled or four-wheeled, but compared with two-wheeled electric vehicles, three-wheeled and four-wheeled electric vehicles have poor flexibility and are not convenient for driving on narrow roads. In the existing technical solutions, the load-carrying device used for two-wheeled electric vehicles for load-carrying has a relatively simple structure. When objects are placed on the load-carrying device, the load-carrying device cannot fix the objects well, which makes it easy for objects to fall off during the transportation of objects by the electric vehicles for load-carrying. Utility Model Content
[0004] The embodiment of the present application provides an easily adjustable load-bearing device for electric bicycles, thereby solving the technical problem that the load-bearing device for two-wheeled electric load-bearing vehicles in the prior art solutions has a relatively simple structure. When objects are placed on the load-bearing device, the load-bearing device cannot fix the objects well, which leads to the problem that objects are easily dropped off during the transportation of objects by the electric load-bearing vehicles.
[0005] The technical solution adopted in the embodiment of the present application is as follows:
[0006] A load-bearing device for an electric bicycle that is easy to adjust, comprising a fixing frame, a supporting assembly for supporting an object, and a fixing assembly for clamping and fixing the object; the supporting assembly is arranged on the fixing frame; the fixing frame is provided with two groups of the fixing assemblies that are symmetrically arranged with respect to the supporting assembly;
[0007] The fixing assembly includes a baffle for abutting against an object, a first threaded rod for driving the baffle to move, and a connecting plate arranged on the fixing frame; the baffle is arranged on the first threaded rod; and the first threaded rod is threadedly connected to the connecting plate.
[0008] A further technical solution is: the supporting assembly includes a stopper, a supporting plate for supporting articles, a slider for driving the supporting plate to slide, a limiting slide rail for limiting the sliding movement of the slider, a second threaded rod for driving the slider to slide, and a bearing seat arranged on the fixed frame; the fixed frame is provided with two groups of limiting slide rails symmetrically arranged with the bearing seat; the two groups of limiting slide rails are slidably connected with the slider; the two groups of sliders are provided with the supporting plate; the second threaded rod is arranged on the inner ring of the bearing in the bearing seat; the stopper is connected to both ends of the second threaded rod; the two groups of sliders are threadedly connected to the second threaded rod; when the second threaded rod rotates, the two groups of sliders will slide close to or away from the corresponding limiting slide rails at the same time.
[0009] A further technical solution is: the fixing assembly further comprises a bending handle; the bending handle is arranged on an end portion of the first threaded rod away from the baffle.
[0010] A further technical solution is: the fixing assembly further includes a damping block; and a plurality of groups of the damping blocks arranged in a rectangular array are arranged on one side of the baffle plate for abutting against the object.
[0011] A further technical solution is: the support assembly also includes a threaded handle; the threaded handle is arranged on one group of the stop blocks.
[0012] A further technical solution is: the support assembly also includes a limit block; and the limit blocks are arranged on both groups of the support plates.
[0013] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:
[0014] 1. Due to the arrangement of the fixing frame, the supporting assembly, the fixing assembly, the baffle plate, the first threaded rod and the connecting plate, when the objects need to be clamped and fixed, the staff first places the objects to be fixed on the supporting assembly, and then the staff works simultaneously through the two sets of fixing assemblies. The staff rotates the two sets of first threaded rods in sequence. Since the two sets of first threaded rods are respectively threadedly connected to the corresponding connecting plates, when the staff rotates the two sets of first threaded rods in sequence, the two sets of first threaded rods will simultaneously drive the two sets of baffle plates to move toward the objects. When the two sets of baffle plates are against both sides of the objects at the same time, the objects placed on the supporting assembly can be effectively fixed. Therefore, when the load-carrying electric vehicle is transporting objects, the objects will no longer fall off.
[0015] 2. Due to the use of the setting of the block, support plate, slider, limit slide rail, second threaded rod and bearing seat, when it is necessary to fix the items, the staff must first place the items on the two groups of support plates, and then fix the items by the two groups of baffles against both sides of the items at the same time. By rotating the second threaded rod, the two groups of sliders can slide close to or away from the corresponding limit slide rails at the same time, thereby driving the two groups of support plates to slide close to or away from each other at the same time. By the two groups of support plates sliding away from each other at the same time, the gap between the two groups of support plates can be increased, thereby enabling larger-sized items to be placed on the two groups of support plates. By adjusting the gap between the two groups of support plates, items of different sizes can be placed on the two groups of support plates, thereby improving the practicality of the load-carrying device for the electric bicycle to a certain extent.
[0016] 3. Due to the setting of the bending handle, the first threaded rod can be driven to rotate together by rotating the bending handle, thereby making it more convenient for the staff to operate.
[0017] 4. Due to the setting of the damping blocks, when the baffles are against the two sides of the objects, the damping blocks on the baffles will contact the objects. The contact between the damping blocks on the baffles and the objects can increase the friction between the baffles and the objects, thereby enabling the two sets of baffles to better clamp and fix the objects.
[0018] 5. Due to the setting of the threaded handle, the second threaded rod can be driven to rotate together by rotating the threaded handle, which makes it more convenient for the staff to operate.
[0019] 6. Due to the setting of the limit blocks, when the objects are placed on the two sets of support plates, the two sets of limit blocks can limit the objects placed on the support plates, thereby preventing the objects from falling off the support plates. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0025] The embodiment of the present application provides an easily adjustable load-bearing device for electric bicycles, thereby solving the technical problem that the load-bearing device for two-wheeled electric load-bearing vehicles in the prior art solutions has a relatively simple structure. When objects are placed on the load-bearing device, the load-bearing device cannot fix the objects well, which leads to the problem that objects are easily dropped off during the transportation of objects by the electric load-bearing vehicles.
[0026] The technical solution in the embodiment of the present application is to solve the above problems, and the overall idea is as follows:
[0027] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0028] A load-carrying device for an electric bicycle that is easy to adjust, such as Figure 1 and Figure 3 As shown, it comprises a fixing frame 1, a supporting assembly 2 for supporting articles, and a fixing assembly 3 for clamping and fixing articles. The supporting assembly 2 is arranged on the fixing frame 1. The fixing frame 1 is provided with two groups of fixing assemblies 3 symmetrically arranged with the supporting assembly 2.
[0029] The fixing assembly 3 includes a baffle 31 for abutting against an object, a first threaded rod 32 for driving the baffle 31 to move, and a connecting plate 33 arranged on the fixing frame 1. The baffle 31 is arranged on the first threaded rod 32. The first threaded rod 32 is threadedly connected to the connecting plate 33.
[0030] The bottom end of the fixing frame 1 is detachably mounted on the rear beam of the electric vehicle by bolts. The support assembly 2 is fixedly connected to the center of the top of the fixing frame 1. Two groups of fixing assemblies 3 are fixedly connected to the top of the fixing frame 1 and are symmetrically arranged with the support assembly 2. The connecting plate 33 is fixedly connected to the top of the fixing frame 1. The baffle 31 is fixedly connected to one end of the first threaded rod 32 in the direction close to the support assembly 2. The connecting plate 33 is provided with a threaded hole adapted to the first threaded rod 32. The first threaded rod 32 is threadedly connected to the threaded hole provided in the connecting plate 33.
[0031] Due to the arrangement of the fixing frame 1, the supporting assembly 2, the fixing assembly 3, the baffle plate 31, the first threaded rod 32 and the connecting plate 33, when it is necessary to clamp and fix the items, the staff first places the items to be fixed on the supporting assembly 2, and then the staff works simultaneously through the two sets of fixing assemblies 3, and the staff rotates the two sets of first threaded rods 32 in sequence. Since the two sets of first threaded rods 32 are respectively threadedly connected to the corresponding connecting plates 33, when the staff rotates the two sets of first threaded rods 32 in sequence, the two sets of first threaded rods 32 will simultaneously drive the two sets of baffle plates 31 to move toward the direction of the items, and when the two sets of baffle plates 31 are simultaneously against both sides of the items, the items placed on the supporting assembly 2 can be effectively fixed. Therefore, when the load-carrying electric vehicle is transporting items, the items will no longer fall off.
[0032] like Figure 2 As shown, the support assembly 2 includes a stopper 21, a support plate 22 for supporting an article, a slider 23 for driving the support plate 22 to slide, a limiting slide rail 24 for limiting the slider 23 to slide, a second threaded rod 25 for driving the slider 23 to slide, and a bearing seat 26 arranged on the fixed frame 1. The fixed frame 1 is provided with two groups of limiting slide rails 24 symmetrically arranged with the bearing seat 26. The two groups of limiting slide rails 24 are both slidably connected with the slider 23. The two groups of sliders 23 are both provided with a support plate 22. The second threaded rod 25 is arranged on the inner ring of the bearing in the bearing seat 26. The second threaded rod 25 is connected with a stopper 21 at both ends. The two groups of sliders 23 are both threadedly connected to the second threaded rod 25. When the second threaded rod 25 rotates, the two groups of sliders 23 will slide close to or away from the corresponding limiting slide rails 24 at the same time.
[0033] The bearing seat 26 is fixedly connected to the center of the top of the fixing frame 1. Two groups of limit rails 24 are fixedly connected to the top of the fixing frame 1 and are symmetrically placed with the bearing seat 26. Two groups of sliders 23 are symmetrically placed with the bearing seat 26. The tops of the two groups of sliders 23 are fixedly connected with support plates 22. The second threaded rod 25 is fixedly connected to the inner ring of the bearing in the bearing seat 26. Stoppers 21 are fixedly connected to both ends of the second threaded rod 25.
[0034] Due to the arrangement of the stopper 21, the support plate 22, the slider 23, the limiting slide rail 24, the second threaded rod 25 and the bearing seat 26, when it is necessary to fix an item, the staff first needs to place the item on the two groups of support plates 22, and then fix the item by abutting the two groups of baffles 31 against both sides of the item at the same time. By rotating the second threaded rod 25, the two groups of sliders 23 can slide close to or slide away from the corresponding limiting slide rails 24 at the same time, thereby driving the two groups of support plates 22 to slide close to or slide away from each other at the same time. By sliding away from each other at the same time by the two groups of support plates 22, the gap between the two groups of support plates 22 can be increased, thereby enabling the two groups of support plates 22 to place items of larger sizes. By adjusting the gap between the two groups of support plates 22, items of different sizes can be placed on the two groups of support plates 22, thereby improving the practicality of the load-carrying device for the electric bicycle to a certain extent.
[0035] like Figure 3 As shown, the fixing assembly 3 further includes a bending handle 34. The bending handle 34 is arranged on an end of the first threaded rod 32 away from the baffle 31.
[0036] The bending handle 34 is fixedly connected to an end of the first threaded rod 32 in a direction away from the baffle 31 .
[0037] Since the bending handle 34 is provided, the first threaded rod 32 can be driven to rotate together by rotating the bending handle 34, thereby making it more convenient for the staff to operate.
[0038] like Figure 4 As shown, the fixing assembly 3 further includes a damping block 35. A plurality of groups of damping blocks 35 arranged in a rectangular array are arranged on one side of the baffle plate 31 for abutting against the object.
[0039] A plurality of damping blocks 35 arranged in a rectangular array are fixedly connected to one side of the baffle plate 31 for abutting against the object.
[0040] Due to the setting of the damping blocks 35, when the baffle 31 is against the two sides of the object, the damping blocks 35 on the baffle 31 will contact the object. The contact between the damping blocks 35 on the baffle 31 and the object can increase the friction between the baffle 31 and the object, thereby enabling the two sets of baffles 31 to better clamp and fix the object.
[0041] like Figure 2 As shown, the support assembly 2 further includes a threaded handle 27. The threaded handle 27 is arranged on one set of the stoppers 21.
[0042] The threaded handle 27 is fixedly connected to one set of the stops 21 .
[0043] Due to the provision of the threaded handle 27, the second threaded rod 25 can be driven to rotate together by rotating the threaded handle 27, thereby making it more convenient for the staff to operate.
[0044] like Figure 2 As shown, the support assembly 2 further includes a limit block 28. The limit blocks 28 are disposed on both sets of support plates 22.
[0045] One end of the top of the two groups of support plates 22 away from the bearing seat 26 is fixedly connected to the limiting block 28.
[0046] Due to the provision of the limiting blocks 28 , when objects are placed on the two groups of support plates 22 , the two groups of limiting blocks 28 can limit the objects placed on the support plates 22 , thereby preventing the objects from falling off the support plates 22 .

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present invention.
[0048] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
