Description

Technical Field

[0001] This invention relates to the field of single-end lifting technology for electric tricycle frames, specifically to a single-end lifting device for electric tricycle frames. Background Technology

[0002] Electric tricycles are light vehicles powered by electricity and equipped with three wheels. In recent years, they have been widely used in urban and rural areas due to their environmentally friendly, economical, and convenient features. They have become a popular choice, especially for elderly people to get around, families to pick up and drop off children, and short-distance shopping. In the use and maintenance of electric tricycles, lifting one side of the frame is a common requirement. Electric tricycles have a simple structure and strong load-bearing capacity. However, the maintenance of the chassis and frame, tire replacement, battery pack installation and removal, and suspension system inspection often require lifting one side of the frame so that one side of the tricycle is off the ground. At this time, one side of the electric tricycle can be repaired or replaced, usually using a lifting device.

[0003] For lifting electric tricycles, manual lifting devices are often used. However, after lifting, multiple locking mechanisms are usually not installed, with only a single locking mechanism at the handlebars. When maintaining the vehicle body or changing tires, the lifting device is usually located on the side. If the handlebars are accidentally touched, the lifting device may fail to lock, causing the lifting structure to fall rapidly. This increases the risk for maintenance personnel and may even lead to injury.

[0004] Therefore, a single-end lifting device for the frame of an electric tricycle is proposed to solve the problems mentioned above. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a single-end lifting device for the frame of an electric tricycle. This solves the problem of lifting electric tricycles, which often involves manual lifting devices. However, after lifting, these devices typically lack multiple locking mechanisms, using only a single locking mechanism at the handlebars. When maintaining the vehicle or changing tires, the lifting device is usually located to the side. Accidental contact with the handlebars can easily cause the locking mechanism to fail, resulting in a rapid descent of the lifting structure. This increases the risk for maintenance personnel and could even lead to injury.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a base is included, a fixed column is fixedly connected to the top of the base, a lifting mechanism is provided inside the fixed column, and the lifting mechanism includes a sliding groove, a rectangular column, a sliding column, a conical corrugation, a support seat, a fixed frame, a handle, a first pawl, a torsion spring, and an arc surface;

[0007] The slide groove is formed inside the fixed column, the rectangular column is slidably connected inside the slide groove, the slide column is fixedly connected to the top of the rectangular column, the conical corrugation is provided on the outside of the slide column, the support is fixedly connected to the top of the slide column, the fixing frame is provided inside the fixed column, the handle is fixedly connected to one side of the fixing frame, the first pawl is rotatably connected to the inside of one end of the fixing frame, the torsion spring is fixedly connected to one side of the first pawl, and the arc surface is provided at the bottom of one end of the first pawl.

[0008] Preferably, one end of the torsion spring is fixedly connected to the fixing frame, the conical corrugations are evenly distributed on the outside of the sliding column, and the outer wall of the rectangular column is in contact with the inner wall of the sliding groove.

[0009] Preferably, the first claw is in contact with the inclined surface of the conical corrugation through an arc surface, the top of the first claw is a horizontal surface, and the top of the first claw is in contact with the bottom of the conical corrugation.

[0010] Preferably, the fixed column is provided with a lowering mechanism, which includes a lever plate, a stop block, a second pawl, a spring plate, a sliding groove, a pull rod, and a tension spring. The lever plate is rotatably connected inside the fixed column, the stop block is fixedly connected to the outside of the fixed column, the second pawl is fixedly connected to one end of the lever plate, the spring plate is fixedly connected inside the fixed column, the sliding groove is opened outside the fixed column, the pull rod is slidably connected to the outside of the fixed column, and the tension spring is fixedly connected to the outside of the pull rod.

[0011] Preferably, the shaft of the fixing frame is slidably connected inside the sliding groove, and the fixing frame is rotatably connected to the sliding groove via the shaft.

[0012] Preferably, one end of the pull rod is inserted into the sliding groove, and one end of the tension spring is fixedly connected to the fixed post.

[0013] Preferably, the pull rod divides the sliding groove into two through grooves, and the inner wall of the through groove is in contact with the outer wall of the side shaft of the fixing frame.

[0014] Preferably, the top of the support is provided with a docking mechanism, which includes a first limiting groove, a polygonal column, a pin hole, a support column, a second limiting groove, a polygonal groove, and a pin. The first limiting groove is opened on the top of the support, the polygonal column is fixedly connected inside the first limiting groove, the pin hole is opened inside the polygonal column, the support column is inserted into the outside of the polygonal column, the second limiting groove is opened on the top of the support column, the polygonal groove is opened on the bottom of the support column, and the pin is fixedly connected inside the polygonal groove.

[0015] Preferably, the pin is slidably inserted into the pin hole, and the polygonal post is inserted into the polygonal slot.

[0016] Preferably, the top of the base has a groove, and the outside of the fixing post is fixedly connected with a clip.

[0017] Compared with the prior art, the present invention provides a single-end lifting device for the frame of an electric tricycle, which has the following advantages:

[0018] 1. By pressing and pulling the handle, the sliding column is lifted. By repeating this process, a segmented lifting effect is achieved, thus completing the effect of lifting one side of the electric tricycle frame.

[0019] After maintenance is completed, the second and first pawls work together to form a double locking effect. When the slide column is to fall and reset quickly, multiple locking positions need to be canceled. This can prevent the slide column from being unlocked and falling due to a single accidental touch. This ensures greater safety and stability during lifting and provides safer support during maintenance.

[0020] 2. When supporting the electric tricycle frame at different positions, the height of the electric tricycle frame off the ground varies at different positions. When encountering a lower support position, a support column is needed to assist in extending the overall height of the equipment. When lifting the frame at a higher position, the operation is easier and the application range is wider.

[0021] 3. The first and second limiting slots are designed to achieve a plug-in effect when in contact with the frame, which ensures a more stable support effect and prevents the device from shifting to the left or right or front and back. When it is not necessary to raise the frame, the support column can be pulled out and engaged with the clip to achieve a storage effect, making it more convenient to carry.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example:

[0033] Please see Figure 1 - Figure 8 The single-end lifting device for the frame of an electric tricycle in this embodiment includes a base 1, a fixed column 2 fixedly connected to the top of the base 1, and a lifting mechanism inside the fixed column 2. The lifting mechanism includes a sliding groove 3, a rectangular column 4, a sliding column 5, a conical corrugated 6, a support seat 7, a fixed frame 8, a handle 9, a first claw 10, a torsion spring 11, and an arc surface 12.

[0034] The slide groove 3 is opened inside the fixed column 2, the rectangular column 4 is slidably connected inside the slide groove 3, the slide column 5 is fixedly connected to the top of the rectangular column 4, the conical corrugation 6 is set outside the slide column 5, the support seat 7 is fixedly connected to the top of the slide column 5, the fixed frame 8 is set inside the fixed column 2, the handle 9 is fixedly connected to one side of the fixed frame 8, the first claw 10 is rotatably connected to the inside of one end of the fixed frame 8, the torsion spring 11 is fixedly connected to one side of the first claw 10, and the arc surface 12 is set at the bottom of one end of the first claw 10.

[0035] When in use, place the device on the side of the electric tricycle frame that needs to be lifted, so that the first limiting groove 17 on the support seat 7 coincides with the frame weight on the side of the frame. Then press the handle 9 to drive the fixed frame 8 to rotate. At the same time, the sliding column 5 is lifted by the horizontal surface of the first claw 10 cooperating with the bottom of the conical corrugation 6. At this time, the second claw 15 rotates outward and compresses the spring plate 16. The second claw 15 is reset by the spring plate 16 and the second claw 15 is engaged in the conical corrugation 6, thereby limiting and fixing the lifted sliding column 5. Then, when the handle 9 is pulled up, the first claw 10 rotates outward through the arc surface 12 and the conical corrugation 6, slides out of one conical corrugation 6, and is placed in the next conical corrugation 6. It is reset by the torsion spring 11 to achieve the effect of secondary engagement. Press the handle 9 down again to lift the sliding column 5. Repeat this process to achieve the effect of segmented lifting and lifting, and complete the effect of lifting one side of the electric tricycle frame.

[0036] The arc surface 12 and the conical surface of the conical corrugation 6 mainly achieve the guiding effect. The first claw 10 and the second claw 15 have the same size and both have the arc surface 12. When the second stage of lifting is performed after the first claw 10 is lifted, the second claw 15 plays the role of auxiliary positioning and applying a bearing effect. The equidistant distribution of the conical corrugations 6 can achieve the lifting effect of multiple positions and multiple heights. The setting of the stop block 14, after the dial plate 13 is reset, positions the dial plate 13. Through the downward pressure of the sliding column 5, combined with the positioning of the stop block 14, a more stable support effect is achieved. At this time, the stop block 14 will not be pressed and rotated.

[0037] Please see Figure 1 - Figure 8 One end of the torsion spring 11 is fixedly connected to the fixed frame 8. The conical corrugations 6 are evenly distributed outside the sliding column 5. The outer wall of the rectangular column 4 is in contact with the inner wall of the sliding groove 3. The first claw 10 is in contact with the inclined surface of the conical corrugations 6 through the arc surface 12. The top of the first claw 10 is a horizontal plane. The top of the first claw 10 is in contact with the bottom of the conical corrugations 6.

[0038] To facilitate descent, a descent mechanism is provided inside the fixed column 2. The descent mechanism includes a lever 13, a stop 14, a second pawl 15, a spring plate 16, a sliding groove 26, a pull rod 27, and a tension spring 28. The lever 13 is rotatably connected inside the fixed column 2, the stop 14 is fixedly connected to the outside of the fixed column 2, the second pawl 15 is fixedly connected to one end of the lever 13, the spring plate 16 is fixedly connected inside the fixed column 2, the sliding groove 26 is opened outside the fixed column 2, the pull rod 27 is slidably connected to the outside of the fixed column 2, and the tension spring 28 is fixedly connected to the outside of the pull rod 27.

[0039] After maintenance is completed, press the handle 9 slightly. The first claw 10 at the end of the handle 9 supports the conical corrugation 6. At this time, the second claw 15 of the lever 13 does not provide support. Press down the lever 13, and the second claw 15 completely disengages from the conical corrugation 6. Then pull the lever 27 upward. The end of the lever 27 disengages from the sliding groove 26. Pull the handle 9 outward. The fixing bracket 8 slides inside the sliding groove 26. The first claw 10 disengages from the conical corrugation 6. At this time, the sliding column 5 quickly falls back to its original position, thus achieving the effect of rapid descent after lifting. The descent operation requires multiple operations to avoid the situation where a single accidental touch causes the sliding column 5 to unlock and fall. This ensures greater safety and stability during lifting and provides safer support during maintenance.

[0040] Please see Figure 1 - Figure 8 The shaft of the fixed frame 8 is slidably connected inside the sliding groove 26. The fixed frame 8 is rotatably connected to the sliding groove 26 via the shaft. One end of the pull rod 27 is inserted into the sliding groove 26, and one end of the tension spring 28 is fixedly connected to the fixed post 2. The pull rod 27 divides the sliding groove 26 into two through grooves. The inner wall of the through groove is in contact with the outer wall of the side shaft of the fixed frame 8. One end of the pull rod 27 can be set to be arc-shaped, which makes it more convenient to reset the sliding of the fixed frame 8.

[0041] To improve practicality, the top of the support 7 is provided with a docking mechanism, which includes a first limiting groove 17, a polygonal column 18, a pin hole 19, a support column 20, a second limiting groove 21, a polygonal groove 22, and a pin 23. The first limiting groove 17 is opened at the top of the support 7. The polygonal column 18 is fixedly connected inside the first limiting groove 17. The pin hole 19 is opened inside the polygonal column 18. The support column 20 is inserted into the outside of the polygonal column 18. The second limiting groove 21 is opened at the top of the support column 20. The polygonal groove 22 is opened at the bottom of the support column 20. The pin 23 is fixedly connected inside the polygonal groove 22. The pin 23 is slidably inserted into the pin hole 19. The polygonal column 18 is inserted into the polygonal groove 22.

[0042] When supporting different positions of the electric tricycle frame, the ground clearance of the frame varies. When encountering a lower support position, such as the footrest position, it can be directly supported by the support seat 7. When encountering a higher position, such as the body part, the polygonal groove 22 of the support column 20 can be inserted into the polygonal column 18 of the support seat 7, and the pin 23 is inserted into the pin hole 19 to achieve the effect of limiting after insertion. At this time, the setting of the support column 20 extends the overall height of the equipment, making the operation easier when lifting the frame at a higher position and expanding the applicability. The setting of the first limiting groove 17 and the second limiting groove 21 achieves the insertion effect when in contact with the frame, which can ensure a more stable support effect and prevent the device from shifting to the left or right or front and back.

[0043] Please see Figure 1 - Figure 8 The top of the base 1 has a groove 24, and the external of the fixing column 2 is fixedly connected with a clip 25. When it is not necessary to raise the frame, the support column 20 can be pulled out and engaged with the clip 25 to achieve the storage effect, making it more convenient to carry.

[0044] The working principle of the above embodiments is as follows:

[0045] When in use, place the device on the side of the electric tricycle frame that needs to be lifted, so that the first limiting groove 17 on the support seat 7 coincides with the frame weight on the side of the frame. Then press the handle 9 to drive the fixed frame 8 to rotate. At the same time, the sliding column 5 is lifted by the horizontal surface of the first claw 10 cooperating with the bottom of the conical corrugation 6. At this time, the second claw 15 rotates outward and compresses the spring plate 16. The second claw 15 is reset by the spring plate 16 and the second claw 15 is engaged in the conical corrugation 6, thereby limiting and fixing the lifted sliding column 5. Then, when the handle 9 is pulled up, the first claw 10 rotates outward through the arc surface 12 and the conical corrugation 6, slides out of one conical corrugation 6, and is placed in the next conical corrugation 6. It is reset by the torsion spring 11 to achieve the effect of secondary engagement. Press the handle 9 down again to lift the sliding column 5. Repeat this process to achieve the effect of segmented lifting and lifting, and complete the effect of lifting one side of the electric tricycle frame.

[0046] After maintenance is completed, press the handle 9 slightly. The first claw 10 at the end of the handle 9 supports the conical corrugation 6. At this time, the second claw 15 of the lever 13 does not provide support. Press down the lever 13, and the second claw 15 completely disengages from the conical corrugation 6. Do not release the lever 13. Press the index finger of the handle 9 and then pull the lever 27 upward or have another person assist in pulling the lever 27. The end of the lever 27 disengages from the sliding groove 26. Pull the handle 9 outward, and the fixing bracket 8 slides inside the sliding groove 26. The first claw 10 disengages from the conical corrugation 6. At this time, the slide column 5 quickly falls back to its original position, thus achieving the effect of rapid descent after lifting. The descent operation requires multiple operations to avoid the situation where a single accidental touch causes the slide column 5 to unlock and fall. This ensures greater safety and stability during lifting and safer support during maintenance.

[0047] The arc surface 12 and the conical surface of the conical corrugation 6 mainly achieve the guiding effect. The first claw 10 and the second claw 15 have the same size and both have the arc surface 12. When the second stage of lifting is performed after the first claw 10 is lifted, the second claw 15 plays the role of auxiliary positioning and applying a bearing effect. The equidistant distribution of the conical corrugation 6 can achieve the lifting effect of multiple positions and multiple heights. The setting of the stop block 14, after the dial plate 13 is reset, positions the dial plate 13. Through the downward pressure of the sliding column 5, combined with the positioning of the stop block 14, a more stable support effect is achieved. At this time, the stop block 14 will not be pressed and rotated.

[0048] When supporting different positions of the electric tricycle frame, the ground clearance of the electric tricycle frame varies at different positions. When encountering a lower support position, such as the foot pedal position, it can be directly supported by the support seat 7. When encountering a higher position, such as the body part, the polygonal groove 22 of the support column 20 can be inserted into the polygonal column 18 of the support seat 7, and the pin 23 is inserted into the pin hole 19 to achieve the effect of limiting after insertion. At this time, the setting of the support column 20 extends the overall height of the equipment, making the operation easier when lifting the frame at a higher position and having a wider range of applications. The setting of the first limiting groove 17 and the second limiting groove 21 achieves the insertion effect when in contact with the frame, which can ensure a more stable support effect and prevent the device from shifting to the left or right or front and back.

[0049] When the raised frame is not needed, the support column 20 can be pulled out and engaged with the clip 25 to achieve a storage effect, making it more convenient to carry.

[0050] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0051] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
