Description

Technical Field

[0001] This utility model relates to the field of anti-tipping technology, and more specifically, to an anti-tipping device for electric tricycles. Background Technology

[0002] First, electric tricycles currently on the market generally pose a risk of reversing when facing uphill sections. Due to their considerable weight and high center of gravity when loaded, electric tricycles are prone to sliding backward on steep slopes. Especially during startup, drivers often need to simultaneously control the vehicle's balance and the accelerator pedal, making the operation difficult. This not only causes driver panic and increases the likelihood of operational errors but can also lead to serious safety accidents such as loss of control and collisions with vehicles or pedestrians behind.

[0003] Secondly, the installation and disassembly design of traditional electric tricycle anti-tipping devices is extremely inconvenient. Most existing anti-tipping devices are fixedly installed, directly connected to the vehicle frame with bolts. Once installed, disassembly is cumbersome, time-consuming, and laborious. This design leads to two significant problems: firstly, on flat roads or when reversing, the anti-tipping device becomes an obstacle, limiting the vehicle's normal maneuverability; secondly, the fixed installation method makes maintenance exceptionally difficult, requiring owners to use specialized tools for installation and disassembly, greatly increasing the complexity of daily use and maintenance. More seriously, frequent disassembly and reassembly can also cause loosening of connections, stripping of threads, and other damage, further reducing the lifespan and reliability of the anti-tipping device. Utility Model Content

[0005] In view of the problems existing in the prior art, this utility model provides an anti-tipping device for electric tricycles to solve the technical problems mentioned in the background art, such as the vehicle body is prone to reversing when going uphill, and the anti-tipping mechanism is difficult to disassemble conveniently when not needed.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: an anti-tipping device for an electric tricycle, comprising an electric vehicle body, an anti-tipping mounting mechanism, an installation and fixing mechanism, and a fixing auxiliary mechanism. The anti-tipping mounting mechanism includes a fixing frame and a rotating sleeve. A power supply assembly is installed at the bottom end of the electric vehicle body, and a wheel assembly is installed at the output end of the power supply assembly. The rotating sleeve is installed on the wheel assembly, and a ratchet is installed at one end of the rotating sleeve. The fixing frame is rotatably connected to the rotating sleeve. A turning block is installed on the side of the fixing frame, and the turning block is unidirectionally rotatable in cooperation with the ratchet. The installation and fixing mechanism includes a locking rod and a bottom fixing tube. A locking tube is rotatably installed at the top end of the bottom fixing tube. The locking rod can be directionally inserted into the bottom fixing tube. A fitting block is installed on the inner wall of the locking tube, and a sticking block is installed on the outer wall of the locking rod. A compression spring is installed on the fitting block. The rotation of the locking tube causes the fitting block to fit the sticking block, and the compression spring can press against the sticking block, so that the sticking block and the fitting block are relatively fixed.

[0008] The present invention is further configured such that the fixing auxiliary mechanism includes a friction ring and a threaded tube. The friction ring is installed at the bottom end of the side wall of the clamping tube. The outer surface of the bottom fixing tube is threadedly connected to the outer wall of the bottom fixing tube. A guide block is installed on the outer wall of the bottom fixing tube. A spiral plate is installed at the top end of the threaded tube. The spiral plate cooperates with the guide block for guidance. A rubber ring is installed at one end of the spiral plate. One end face of the rubber ring can press against the bottom end of the friction ring, so that the clamping tube is rotated and fixed on the bottom fixing tube.

[0009] The present invention is further configured such that a mounting bracket is installed at the top end of the fixing frame, the bottom fixing tube is fixedly installed on the mounting bracket, and the mounting bracket is installed on the top of the fixing frame to provide a mounting foundation for the bottom fixing tube and enhance the overall structural stability.

[0010] The present invention is further configured such that an installation plate is installed on the electric vehicle body, and one end of the snap-fit ​​rod can pass through the installation plate and the installation frame to quickly snap-fit ​​with the snap-fit ​​tube. The installation plate is installed on the electric vehicle body and corresponds to the installation frame, which facilitates the snap-fit ​​rod to pass through and connect.

[0011] The present invention is further configured such that the insert block has an insert groove, and the insert groove can insert the patch block, and the compression spring is symmetrically installed in the insert groove. The insert block is installed on the inner wall of the snap-fit ​​tube and has an insert groove, so that the patch block on the snap-fit ​​rod can be inserted and fixed to achieve a firm connection.

[0012] The present invention is further configured such that a limiting ring is installed on the inner wall of the bottom fixing tube, and a thrust spring is installed on the side wall of the locking rod, and one end of the thrust spring can contact the bottom end of the limiting ring. The thrust spring contacts the limiting ring on the inner wall of the bottom fixing tube, and provides elastic force to assist the locking rod to pop out when unlocking, which is convenient for disassembly.

[0013] The present invention is further configured such that another set of mounting and fixing mechanisms and fixing auxiliary mechanisms are installed on the rotating sleeve, so that the rotating sleeve and the wheel assembly are detachably and fixedly connected.

[0014] The present invention is further configured such that a support sleeve is installed on one side of the electric vehicle body, and a ground support rod is slidably installed inside the support sleeve.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides an anti-tipping device for electric tricycles, which has the following beneficial effects:

[0017] This utility model features an anti-tipping installation mechanism. Through the ingenious combination of a fixing frame, a rotating sleeve, a ratchet, and a turning block, it effectively solves the problem of electric tricycles easily reversing while going uphill. The one-way rotation mechanism formed by the ratchet and the turning block allows the wheels to rotate freely in the forward direction, while locking immediately when a backward tendency occurs, preventing the vehicle from sliding uncontrollably backward on the slope. This significantly improves driving safety, especially ensuring the safety of use by the elderly and other special groups.

[0018] This utility model features an installation and fixing mechanism. Through the combined design of a snap-fit ​​rod, a bottom fixing tube, a snap-fit ​​tube, a fitting block, and a sticking block, it completely solves the problem of the difficulty in convenient disassembly of traditional anti-tipping devices. The quick snap-fit ​​structure makes the installation and disassembly process simple and efficient, and can be completed without professional tools. The design of the compression spring and the thrust spring ensures both the firmness of the connection and the ease of unlocking and disassembly, allowing users to flexibly decide whether to activate the anti-tipping function according to road conditions, thus improving the daily convenience of vehicle use.

[0019] This utility model is equipped with a fixed auxiliary mechanism. Through the combination of friction ring, threaded tube, guide block, spiral plate and rubber ring, it provides additional safety for the entire anti-tipping system. The friction locking mechanism can prevent the locking tube from loosening during vehicle vibration, ensuring that the anti-tipping function continues to work reliably. The cooperative design of the guide block and spiral plate makes the adjustment operation more precise and smooth, further improving the stability and reliability of the device under complex road conditions.

[0029] Please see Figures 1-5An anti-tipping device for an electric tricycle includes an electric vehicle body 1, an anti-tipping mounting mechanism, a mounting and fixing mechanism, and a fixing auxiliary mechanism. The anti-tipping mounting mechanism includes a fixing frame 2 and a rotating sleeve 3. A power supply assembly 4 is installed at the bottom end of the electric vehicle body 1, and a wheel assembly 5 is installed at the output end of the power supply assembly 4. The rotating sleeve 3 is installed on the wheel assembly 5, and a ratchet 6 is installed at one end of the rotating sleeve 3. The fixing frame 2 is rotatably connected to the rotating sleeve 3. A turning block 7 is installed on the side of the fixing frame 2, and the turning block 7 cooperates with the ratchet 6. The rotating mounting and fixing mechanism includes a snap-fit ​​rod 8 and a bottom fixing tube 9. A snap-fit ​​tube 10 is rotatably mounted on the top end of the bottom fixing tube 9. The snap-fit ​​rod 8 can be directionally inserted into the bottom fixing tube 9. A fitting block 11 is installed on the inner wall of the snap-fit ​​tube 10, and a sticking block 12 is installed on the outer wall of the snap-fit ​​rod 8. A compression spring 13 is installed on the fitting block 11. The rotation of the snap-fit ​​tube 10 causes the fitting block 11 to fit the sticking block 12, and the compression spring 13 can press against the sticking block 12, so that the sticking block 12 and the fitting block 11 are relatively fixed.

[0030] In this embodiment, the anti-tipping installation mechanism achieves the function of preventing the vehicle from moving backward through the cooperation of the fixing frame 2 and the rotating sleeve 3. During operation, the rotating sleeve 3 is installed on the wheel assembly 5, and a ratchet 6 is provided at one end. The fixing frame 2 and the rotating sleeve 3 form a rotatable connection. The rotating block 7 on the side of the fixing frame 2 cooperates with the ratchet 6 to achieve unidirectional rotation restriction. When the electric tricycle has a tendency to move backward, the wheel assembly 5 drives the rotating sleeve 3 to rotate in the opposite direction. At this time, the ratchet 6 engages with the rotating block 7, preventing the reverse rotation, thereby preventing the vehicle from moving backward. In the forward direction, ratchet 6 can freely pass over turn block 7 without affecting normal driving. The mounting and fixing mechanism achieves quick connection between the anti-tipping device and the vehicle body through the cooperation of snap-fit ​​rod 8 and bottom fixing tube 9. During operation, snap-fit ​​rod 8 extends into bottom fixing tube 9 in a directional direction. Snap-fit ​​tube 10 at the top of bottom fixing tube 9 can be limited to rotation. After rotating snap-fit ​​tube 10, the insert block 11 on the inner wall of snap-fit ​​tube 10 inserts the patch block 12 on the outer wall of snap-fit ​​rod 8. The compression spring 13 on insert block 11 applies pressure to patch block 12 to ensure that patch block 12 is tightly fixed to insert block 11. The snap-fit ​​design allows the anti-tipping device to be firmly connected to the electric vehicle body 1. Reverse rotation of snap-fit ​​tube 10 releases the snap-fit, causing mounting bracket 19 to detach from mounting plate 20. At this time, fixing bracket 2 and rotating sleeve 3 rotate synchronously, and ratchet 6 mechanism stops working, achieving convenient quick installation and disassembly.

[0031] The fixing auxiliary mechanism includes a friction ring 14 and a threaded tube 15. The friction ring 14 is installed at the bottom end of the side wall of the clamping tube 10. The outer surface of the bottom fixing tube 9 is threadedly connected to the outer wall of the bottom fixing tube 9. A guide block 16 is installed on the outer wall of the bottom fixing tube 9. A spiral plate 17 is installed at the top end of the threaded tube 15. The spiral plate 17 cooperates with the guide block 16 for guidance. A rubber ring 18 is installed at one end of the spiral plate 17. One end face of the rubber ring 18 can press against the bottom end of the friction ring 14, so that the clamping tube 10 is rotated and fixed on the bottom fixing tube 9.

[0032] In this embodiment, the fixing auxiliary mechanism provides additional locking protection through the cooperation of friction ring 14 and threaded tube 15. Friction ring 14 is installed at the bottom of the side wall of clamping tube 10, and threaded tube 15 is threaded to the outer wall of bottom fixing tube 9. When the threaded tube 15 is rotated, the guide block 16 on the outer wall of bottom fixing tube 9 cooperates with the spiral plate 17 at the top of threaded tube 15 to provide guidance, so that the rubber ring 18 on threaded tube 15 is pressed against the bottom of friction ring 14, increasing friction and preventing clamping tube 10 from loosening or rotating accidentally during vehicle vibration. The friction locking mechanism ensures the reliability of the anti-tipping function under various road conditions.

[0033] Please see Figures 1-5 As a supplementary embodiment of an anti-tipping device for an electric tricycle, which includes an anti-tipping installation mechanism, an installation fixing mechanism, and a fixing auxiliary mechanism: A mounting bracket 19 is installed at the top end of the fixing frame 2, and a bottom fixing tube 9 is fixedly installed on the mounting bracket 19. A mounting plate 20 is installed on the electric vehicle body 1. One end of the snap-fit ​​rod 8 can pass through the mounting plate 20 and the mounting bracket 19 to quickly snap into place with the snap-fit ​​tube 10. A fitting groove 21 is provided on the fitting block 11, and the fitting groove 21 allows the patch block 12 to be fitted into it. The compression springs 13 are symmetrically installed within the fitting groove 21. A limiting ring 22 is installed on the inner wall of the bottom fixing tube 9, and a thrust spring 23 is installed on the side wall of the snap-fit ​​rod 8. One end of the thrust spring 23 can contact the bottom end of the limiting ring 22. Another set of mounting and fixing mechanisms and fixing auxiliary mechanisms are installed on the rotating sleeve 3, so that the rotating sleeve 3 and the wheel assembly 5 are detachably fixed. A support sleeve 24 is installed on one side of the electric vehicle body 1, and a ground support rod 25 is slidably installed inside the support sleeve 24. Bolts can pass through the support sleeve 24 and the ground support rod 25 to fix the support sleeve 24 and the ground support rod 25 relatively.

[0034] More specifically, the fixing bracket 2 is fixed to the electric vehicle body 1 via the mounting bracket 19, the bottom fixing tube 9 is fixed to the mounting bracket 19, and the swivel sleeve 3 is detachably connected to the wheel assembly 5 via another set of mounting and fixing mechanisms. The snap-fit ​​rod 8 passes through the mounting plate 20 and the mounting bracket 19 on the electric vehicle body 1 and extends into the bottom fixing tube 9. Rotating the snap-fit ​​tube 10 causes the insert block 11 to fit and lock the pad block 12. Rotating the threaded tube 15 causes the rubber ring 18 to press against the friction ring 14. The spiral plate 17 cooperates with the guide block 16 to ensure smooth rotation and form a stable friction lock to prevent vibration. When the vehicle moves forward, the ratchet 6 can freely pass over the turn block 7. When the vehicle tends to move backward, the ratchet 6 engages with the turn block 7. The one-way rotation characteristic prevents the wheel from rotating in the opposite direction and prevents backward movement. If necessary, the height of the support rod 25 in the support sleeve 24 can be adjusted and locked to provide additional support. Loosen the threaded tube 15 to release the pressure of the rubber ring 18 on the friction ring 14. Rotate the clamping tube 10 in the opposite direction to release the pad 12. The clamping rod 8 is partially ejected under the action of the thrust spring 23. Pull out the clamping rod 8 to give the fixing bracket 2, the turn block 3 and the ratchet 6 freedom, and complete the disassembly.

[0035] In summary, during use or operation of the overall equipment: When the anti-tipping mechanism is required, it prevents the vehicle from rolling backward through the cooperation of the fixed frame 2 and the rotating sleeve 3. During operation, the rotating sleeve 3 is mounted on the wheel assembly 5, with a ratchet 6 at one end. The fixed frame 2 and the rotating sleeve 3 are rotatably connected. The turntable block 7 on the side of the fixed frame 2 engages with the ratchet 6 to restrict rotation in one direction. When the electric tricycle tends to roll backward, the wheel assembly 5 drives the rotating sleeve 3 to rotate in the opposite direction. At this time, the ratchet 6 engages with the turntable block 7, preventing reverse rotation and thus preventing the vehicle from rolling backward. In the forward direction, the ratchet 6 can freely pass over the turntable block 7 without affecting normal driving.

[0036] When the mounting mechanism is in operation, the mounting mechanism achieves a quick connection between the anti-tipping device and the vehicle body through the cooperation of the snap-fit ​​rod 8 and the bottom fixing tube 9. During operation, the snap-fit ​​rod 8 extends into the bottom fixing tube 9 in a directional manner, and the snap-fit ​​tube 10 at the top of the bottom fixing tube 9 can be limited to rotate. After rotating the snap-fit ​​tube 10, the insert block 11 on the inner wall of the snap-fit ​​tube 10 fits the patch block 12 on the outer wall of the snap-fit ​​rod 8. The compression spring 13 on the insert block 11 applies pressure to the patch block 12 to ensure that the patch block 12 is tightly fixed to the insert block 11. The snap-fit ​​design allows the anti-tipping device to be firmly connected to the electric vehicle body 1. Reverse rotation of the snap-fit ​​tube 10 releases the snap-fit, allowing the mounting bracket 19 to detach from the mounting plate 20. At this time, the fixing bracket 2 and the rotating sleeve 3 rotate synchronously, and the ratchet mechanism 6 stops working, realizing the convenience of quick installation and disassembly.

[0037] When the auxiliary fixing mechanism is required to operate, it provides additional locking protection through the cooperation of friction ring 14 and threaded tube 15. Friction ring 14 is installed at the bottom of the side wall of clamping tube 10, and threaded tube 15 is threaded to the outer wall of bottom fixing tube 9. When the threaded tube 15 is rotated, the guide block 16 on the outer wall of bottom fixing tube 9 cooperates with the spiral plate 17 at the top of threaded tube 15 to provide guidance, so that the rubber ring 18 on threaded tube 15 is pressed against the bottom of friction ring 14, increasing friction and preventing clamping tube 10 from loosening or rotating accidentally during vehicle vibration. The friction locking mechanism ensures the reliability of the anti-tipping function under various road conditions.

[0038] The fixing bracket 2 is fixed to the electric vehicle body 1 via the mounting bracket 19. The bottom fixing tube 9 is fixed to the mounting bracket 19. The swivel sleeve 3 is detachably connected to the wheel assembly 5 via another set of mounting and fixing mechanisms. The snap-fit ​​rod 8 passes through the mounting plate 20 and the mounting bracket 19 on the electric vehicle body 1 and extends into the bottom fixing tube 9. Rotating the snap-fit ​​tube 10 causes the insert block 11 to fit and lock the pad block 12. Rotating the threaded tube 15 causes the rubber ring 18 to press against the friction ring 14. The spiral plate 17 cooperates with the guide block 16 to ensure smooth rotation and form a stable friction lock to prevent vibration and loosening. When the vehicle moves forward, ratchet 6 can freely pass over turn block 7. When the vehicle tends to move backward, ratchet 6 engages with turn block 7. The one-way rotation characteristic prevents the wheel from rotating in the opposite direction and prevents backward movement. If necessary, the height of the support rod 25 in the support sleeve 24 can be adjusted and locked to provide additional support. Loosen the threaded tube 15 to release the pressure of the rubber ring 18 on the friction ring 14. Rotate the locking tube 10 in the opposite direction to release the pad 12. The locking rod 8 is partially ejected under the action of the thrust spring 23. Pull out the locking rod 8 to give the fixing frame 2, the turn block 3 and ratchet 6 freedom, and complete the disassembly.
