Description

Technical Field

[0001] The utility model relates to the field of electric bicycles, in particular to a load-bearing device with good supporting effect. 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 racks used for two-wheeled electric vehicles for load-carrying have a relatively simple structure, which makes the load-carrying racks themselves unreliable and cannot be used for placing heavier goods, which in turn causes the load-carrying racks to be limited in use. Utility Model Content

[0004] The embodiment of the present application solves the technical problem that the load-bearing racks used for two-wheeled load-bearing electric vehicles in the prior art solutions have relatively simple structures, which makes the load-bearing racks themselves unstable and therefore cannot be used for placing heavier goods, which in turn causes the load-bearing racks to be subject to limitations when in use.

[0005] The technical solution adopted in the embodiment of the present application is as follows:

[0006] A load-bearing device with good supporting effect, comprising a base mounted on the rear beam of an electric vehicle frame, a load-bearing rack for supporting goods, a positioning mechanism for positioning goods, a sliding device for driving the positioning mechanism to move, and a supporting assembly for supporting the load-bearing rack; the sliding device and the supporting assembly are both arranged between the base and the load-bearing rack; the two ends of the load-bearing rack are slidably connected with the positioning mechanism; two sets of the positioning mechanism are both arranged on the sliding end of the sliding device;

[0007] The support assembly includes reinforcing ribs, a support rod arranged on the base and a swinging part for supporting the positioning mechanism; the reinforcing ribs are connected to the support rod and the load-carrying shelf; the support rod is connected to the load-carrying shelf; two groups of swinging parts are symmetrically placed with the support rod on the base; both groups of swinging parts are connected to the load-carrying shelf; the swinging part includes a first telescopic rod, a first pin shaft seat arranged on the base and a second pin shaft seat arranged on the load-carrying shelf; the telescopic end of the first telescopic rod is hinged on the first pin shaft seat; the other end of the first telescopic rod is hinged on the second pin shaft seat.

[0008] A further technical solution is: the sliding device includes a ball bearing, a slider for driving the positioning mechanism to move, a threaded rod for driving the slider to slide, and a support seat arranged on the base; the threaded rod is arranged on the inner ring of the ball bearing; both ends of the threaded rod are threadedly connected with the slider, and the two groups of sliders are symmetrically placed around the ball bearing; the two groups of sliders are respectively connected to the positioning mechanism; the ball bearing is arranged on the support seat; the support seat is connected to the load-bearing shelf.

[0009] A further technical solution is: the positioning mechanism includes a support plate, a positioning plate for abutting against the goods, a spring for buffering the positioning plate, a second telescopic rod for limiting the spring, and a movable plate sliding in the load-carrying shelf; the support plate is arranged on the movable plate; the movable plate is connected to the slider; the spring is arranged around the second telescopic rod; the telescopic end of the second telescopic rod is connected to the positioning plate; the other end of the second telescopic rod is connected to the support plate.

[0010] A further technical solution is: the sliding device also includes a threaded handle; the threaded handle is arranged at one end of the threaded rod.

[0011] A further technical solution is: the positioning mechanism also includes a rubber pad; the rubber pad is arranged on the positioning plate.

[0012] A further technical solution is that mounting holes are provided at both ends of the base.

[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 use of the base, load-bearing shelf, positioning mechanism, sliding device and support assembly, when the goods need to be fixed, the staff first places the goods on the load-bearing shelf, and then works through the sliding end of the sliding device to make the two sets of positioning mechanisms move close to the goods, and make the two sets of positioning mechanisms lean against the goods at the same time, and then the goods can be fixed. Since the spacing between the two sets of positioning mechanisms can be adjusted according to the operation of the sliding device, it is possible to fix goods of different sizes and models between the two sets of positioning mechanisms, thereby improving the practicality of the load-bearing device to a certain extent. Due to the use of the reinforcement ribs, support rods and swing parts, since the support rods are fixedly connected between the base and the load-bearing shelf, and the connection between the support rods and the base and between the support rods and the load-bearing shelf are fixedly connected with reinforcement ribs, the structure of the load-bearing shelf can be made more reliable when supporting the goods. Due to the arrangement of the first telescopic rod, the first pin shaft seat and the second pin shaft seat, when the sliding end of the sliding device works, causing the two sets of positioning mechanisms to slide away from the load-bearing rack or slide close to the load-bearing rack at the same time, the first telescopic rod itself will automatically extend and retract along with the movement of the positioning mechanism. Therefore, the first telescopic rod will also play a certain supporting role on the positioning mechanism, thereby making the structure of the load-bearing device more reliable, so that the load-bearing device can be used to support heavier goods.

[0015] 2. Due to the use of ball bearings, sliders, threaded rods and support seats, the two sets of sliders are threadedly connected to the threaded rods, the two sets of sliders are respectively fixedly connected with positioning mechanisms, and the two sets of positioning mechanisms are slidably connected to the two ends of the load-carrying rack. Therefore, by rotating the threaded rods, the staff can make the two sets of sliders slide close to the ball bearings or slide away from the ball bearings at the same time along the threaded rods. During the movement of the two sets of sliders, the two sets of positioning mechanisms can slide away from the load-carrying rack or slide close to the load-carrying rack at the same time. The entire operation process is simple and reliable, and is convenient for the staff to operate.

[0016] 3. Due to the use of the support plate, positioning plate, spring, second telescopic rod and mobile plate, when the two sets of sliders drive the corresponding positioning mechanism to slide by rotating the threaded rod, the mobile plates in the two sets of positioning mechanisms will slide along the slideways opened at both ends of the load-carrying shelf. When the goods are placed on the load-carrying shelf and need to be fixed, the staff first rotates the threaded rod to make the two sets of sliders slide close to each other. During the sliding process of the two sets of sliders, the two sets of mobile plates will be driven to move close to each other, so that the two sets of positioning plates can slide close to the goods. When the two sets of positioning plates are against the goods, the goods will simultaneously produce a certain extrusion force on the two sets of positioning plates, so that the two sets of positioning plates can compress the corresponding springs and the second telescopic rods respectively. At this time, the springs in the compressed state will produce a certain reaction force on the positioning plates, so that the two sets of positioning plates can be firmly against the goods, and the goods can be well positioned at this time. When the spring is in a compressed state, the second telescopic rod can prevent the spring from deforming, so that it can play a certain protective role on the spring.

[0017] 4. Due to the setting of the threaded handle, the staff can drive the threaded rod to rotate by turning the threaded handle, which makes it more convenient for the staff to operate.

[0018] 5. Due to the setting of rubber pads, when the positioning plate is against the goods, the rubber pads on the positioning plate will contact the goods, thereby preventing the positioning plate from causing unnecessary wear to the goods, and thus enabling the positioning plate to play a certain protective role on the goods when clamping the goods.

DETAILED DESCRIPTION

[0025] The embodiment of the present application solves the technical problem that the load-bearing racks used for two-wheeled load-bearing electric vehicles in the prior art solutions have relatively simple structures, which makes the load-bearing racks themselves unstable and therefore cannot be used for placing heavier goods, which in turn causes the load-bearing racks to be subject to limitations when in use.

[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-bearing device with good supporting effect, such as Figure 1 , Figure 2 as well as Figure 3 As shown, it includes a base 1 installed on the rear beam of the electric vehicle frame, a load-carrying rack 2 for supporting goods, a positioning mechanism 3 for positioning goods, a sliding device 4 for driving the positioning mechanism 3 to move, and a support assembly 5 for supporting the load-carrying rack 2.

The reinforcing rib 51 is connected to the support rod 52 and the load-carrying shelf 2. The support rod 52 is connected to the load-carrying shelf 2. Two groups of swinging parts 53 are arranged on the base 1 and are symmetrically arranged with the support rod 52. Both groups of swinging parts 53 are connected to the load-carrying shelf 2. The swinging part 53 includes a first telescopic rod 531, a first pin shaft seat 532 arranged on the base 1, and a second pin shaft seat 533 arranged on the load-carrying shelf 2. The telescopic end of the first telescopic rod 531 is hinged on the first pin shaft seat 532. The other end of the first telescopic rod 531 is hinged on the second pin shaft seat 533.

[0030] Both ends of the base 1 are provided with mounting holes. The base 1 is detachably fixed on the rear beam of the electric vehicle frame through the mounting holes and suitable bolts. The sliding device 4 is fixedly connected to the middle position of the top of the base 1. The load-carrying shelf 2 is fixedly connected to the top of the sliding device 4. Two groups of support components 5 symmetrically arranged with the sliding device 4 are fixedly connected to the top of the base 1. Both groups of support components 5 are fixedly connected to the bottom of the load-carrying shelf 2. Both groups of positioning mechanisms 3 are fixedly connected to the sliding end of the sliding device 4. When the sliding end of the sliding device 4 works, it can drive the two groups of positioning mechanisms 3 to slide away from the load-carrying shelf 2 at the same time or slide close to the load-carrying shelf 2 at the same time.

[0031] The bottom of the support rod 52 is fixedly connected to the top of the base 1. The top of the support rod 52 is fixedly connected to the bottom of the load-carrying rack 2. Two groups of reinforcing ribs 51 symmetrically arranged with the support rod 52 are fixedly connected to both the upper and lower ends of the support rod 52. The two groups of reinforcing ribs 51 located at the top of the support rod 52 are fixedly connected to the bottom of the load-carrying rack 2. The two groups of reinforcing ribs 51 located at the bottom of the support rod 52 are fixedly connected to the top of the base 1. Two groups of swinging parts 53 symmetrically arranged with the support rod 52 are fixedly connected to the top of the base 1. Both groups of swinging parts 53 are fixedly connected to the bottom of the load-carrying rack 2. The first pin shaft seat 532 is fixedly connected to the top of the base 1. The second pin shaft seat 533 is fixedly connected to the bottom of the load-carrying rack 2. The telescopic end of the first telescopic rod 531 is swingably connected to the pin shaft in the first pin shaft seat 532. The other end of the first telescopic rod 531 is swingably connected to the pin shaft in the second pin shaft seat 533.

[0032] Due to the use of the arrangement of the base 1, the load-carrying rack 2, the positioning mechanism 3, the sliding device 4 and the support assembly 5, when the goods need to be fixed, the staff first places the goods on the load-carrying rack 2, and then works through the sliding end of the sliding device 4, so that the two groups of positioning mechanisms 3 move close to the goods, and the two groups of positioning mechanisms 3 are simultaneously against the goods, and the goods can be fixed at this time. Since the spacing between the two groups of positioning mechanisms 3 can be adjusted according to the operation of the sliding device 4, it is possible to fix goods of different sizes and models between the two groups of positioning mechanisms 3, thereby improving the practicality of the load-carrying device to a certain extent. Due to the use of the arrangement of the reinforcing rib 51, the support rod 52 and the swinging part 53, since the support rod 52 is fixedly connected between the base 1 and the load-carrying rack 2, and the connection between the support rod 52 and the base 1 and between the support rod 52 and the load-carrying rack 2 is fixedly connected with the reinforcing rib 51, the structure of the load-carrying rack 2 can be made more reliable when the load-carrying rack 2 supports the goods. Due to the arrangement of the first telescopic rod 531, the first pin shaft seat 532 and the second pin shaft seat 533, when the sliding end of the sliding device 4 works, so that the two sets of positioning mechanisms 3 slide away from the load-bearing shelf 2 at the same time or slide close to the load-bearing shelf 2 at the same time, the first telescopic rod 531 itself will automatically extend and retract along with the movement of the positioning mechanism 3. Therefore, the first telescopic rod 531 will also play a certain supporting role on the positioning mechanism 3, thereby making the structure of the load-bearing device more reliable, so that the load-bearing device can be used to support heavier goods.

[0033] like Figure 4 As shown, the sliding device 4 includes a ball bearing 41, a slider 42 for driving the positioning mechanism 3 to move, a threaded rod 43 for driving the slider 42 to slide, and a support seat 44 arranged on the base 1. The threaded rod 43 is arranged on the inner ring of the ball bearing 41. Both ends of the threaded rod 43 are threadedly connected with the slider 42, and the two groups of sliders 42 are symmetrically placed with the ball bearing 41. The two groups of sliders 42 are respectively connected to the positioning mechanism 3. The ball bearing 41 is arranged on the support seat 44. The support seat 44 is connected to the load-carrying shelf 2.

[0034] The bottom end of the support seat 44 is fixedly connected to the top of the base 1. The top end of the support seat 44 is fixedly connected to the bottom of the load-carrying rack 2. The threaded rod 43 is fixedly connected to the inner ring of the ball bearing 41. The two sets of sliders 42 are respectively fixedly connected to the positioning mechanism 3. The ball bearing 41 is fixedly connected to the support seat 44.

[0035] Due to the arrangement of the ball bearing 41, the slider 42, the threaded rod 43 and the support seat 44, the two sets of sliders 42 are both threadedly connected to the threaded rod 43, the two sets of sliders 42 are respectively fixedly connected with the positioning mechanism 3, and the two sets of positioning mechanisms 3 are both slidably connected to the two ends of the load-carrying shelf 2, so the staff can make the two sets of sliders 42 slide close to the ball bearing 41 or slide away from the ball bearing 41 along the threaded rod 43 by rotating the threaded rod 43. During the movement of the two sets of sliders 42, the two sets of positioning mechanisms 3 can slide away from the load-carrying shelf 2 or slide close to the load-carrying shelf 2 at the same time, and the whole operation process is simple and reliable, which is convenient for the staff to operate.

[0036] like Figure 5 As shown, the positioning mechanism 3 includes a support plate 31, a positioning plate 32 for abutting against the goods, a spring 33 for buffering the positioning plate 32, a second telescopic rod 34 for limiting the spring 33, and a moving plate 35 sliding in the load-carrying shelf 2. The support plate 31 is arranged on the moving plate 35. The moving plate 35 is connected to the slider 42. The spring 33 is arranged around the second telescopic rod 34. The telescopic end of the second telescopic rod 34 is connected to the positioning plate 32. The other end of the second telescopic rod 34 is connected to the support plate 31.

[0037] Both ends of the load-carrying rack 2 are provided with slideways adapted to the moving plate 35. The support plate 31 is fixedly connected to the moving plate 35. The moving plate 35 is fixedly connected to the slider 42. A plurality of groups of second telescopic rods 34 arranged in a linear array are provided on the support plate 31. A corresponding spring 33 is arranged around the outside of each group of second telescopic rods 34. The telescopic end of each group of second telescopic rods 34 is fixedly connected to the positioning plate 32. The other end of each group of second telescopic rods 34 is fixedly connected to the support plate 31. One end of each group of springs 33 is fixedly connected to the positioning plate 32. The other end of each group of springs 33 is fixedly connected to the support plate 31.

[0038] Due to the arrangement of the support plate 31, the positioning plate 32, the spring 33, the second telescopic rod 34 and the moving plate 35, when the two sets of sliders 42 are respectively driven to slide the corresponding positioning mechanism 3 by rotating the threaded rod 43, the moving plates 35 in the two sets of positioning mechanisms 3 will slide along the slideways opened at both ends of the load-carrying shelf 2. When the goods are placed on the load-carrying shelf 2 and need to be fixed, the staff first rotates the threaded rod 43 to make the two sets of sliders 42 approach to slide. During the approach of the two sets of sliders 42, the corresponding two sets of moving plates 35 will be driven to move, so that the two sets of positioning plates 32 can slide close to the goods. When the two sets of positioning plates 32 are against the goods, the goods will simultaneously produce a certain extrusion force on the two sets of positioning plates 32, so that the two sets of positioning plates 32 can compress the corresponding springs 33 and the second telescopic rod 34 respectively. At this time, the springs 33 in the compressed state will produce a certain reaction force on the positioning plates 32, so that the two sets of positioning plates 32 can be firmly against the goods, and the goods can be well positioned at this time. When the spring 33 is in a compressed state, the second telescopic rod 34 can prevent the spring 33 from deforming, thereby protecting the spring 33 to a certain extent.

[0039] like Figure 4 As shown, the sliding device 4 further includes a threaded handle 45. The threaded handle 45 is arranged at one end of the threaded rod 43.

[0040] The threaded handle 45 is fixedly connected to one end of the threaded rod 43 .

[0041] Due to the provision of the threaded handle 45 , the staff can drive the threaded rod 43 to rotate together by rotating the threaded handle 45 , thereby making the operation more convenient for the staff.

[0042] like Figure 5 As shown, the positioning mechanism 3 further includes a rubber pad 36 . The rubber pad 36 is arranged on the positioning plate 32 .

[0043] A plurality of groups of rubber pads 36 arranged in a linear array are fixedly connected to the positioning plate 32 .

[0044] Due to the provision of the rubber pads 36, when the positioning plate 32 rests against the cargo, the rubber pads 36 on the positioning plate 32 will contact the cargo, thereby preventing the positioning plate 32 from causing unnecessary wear on the cargo, and further enabling the positioning plate 32 to play a certain protective role on the cargo when clamping the cargo.

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.
