Description

Technical Field

[0001] This utility model relates to the field of front guardrail technology for electric tricycles, and more specifically, to a front guardrail for electric tricycles. Background Technology

[0002] In existing technologies, the front guardrail, as an important protective and aesthetic component of electric tricycles, directly affects the safety and practicality of vehicle use due to its stable installation and ease of disassembly. However, existing front guardrail designs have many problems that urgently need to be solved, especially in terms of installation structure and ease of operation. Traditional front guardrail installation methods bring many inconveniences in practical applications. When it is necessary to install the front guardrail on the front of the electric tricycle or to remove it from the front, the operation process is cumbersome and complicated, usually requiring the use of various professional tools such as wrenches and screwdrivers, which increases the user's tool preparation costs. This complicated disassembly and assembly process is not only time-consuming and labor-intensive, but also prone to problems such as stripped threads and damaged parts due to improper operation. For ordinary users, this design greatly reduces the user-friendliness of the product. Especially in emergency situations where the front guardrail needs to be quickly disassembled, the cumbersome operation process may delay the processing time and prevent convenient disassembly and assembly of the front guardrail.

[0003] Secondly, some manufacturers have recognized the aforementioned problems and attempted to solve the cumbersome disassembly and assembly of the front guardrail by improving the design. These improved models have initially achieved convenient disassembly and assembly of the front guardrail without the aid of tools. However, these solutions often prioritize ease of operation over connection stability. This is reflected in their overly simple and crude structural design, lacking necessary anti-loosening design, resulting in low overall stability. During daily operation, especially on uneven roads, electric tricycles experience continuous vibrations and periodic impacts. These vibrations continuously act on the connection structure of the front guardrail, causing the simple connection device to gradually loosen. In addition, the instantaneous impact force generated by sudden road obstacles, emergency braking, or collisions is more likely to cause the connection mechanism to loosen or fail. As the usage time increases, the reliability of the connection gradually decreases, which may eventually lead to the front guardrail loosening or even completely falling off during operation. Once the front guardrail falls off, it will not only damage the vehicle itself but may also cause traffic accidents, endangering the personal safety of the driver and other road users. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the problems existing in the prior art, the present invention provides a front guardrail for electric tricycles to solve the technical problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a front guard frame for an electric tricycle, comprising a crossbeam, connecting beams fixedly connected to both sides of the crossbeam, an mounting plate fixedly mounted on the inner side of the connecting beams, a detachable locking sleeve on one side of the mounting plate, a detachable locking rod on the inner side of the locking sleeve, a rotatable movable plate rotatably mounted on the outer side of the locking sleeve, a movable hole formed on the movable plate, a linkage block fixedly connected to one side of the movable plate, a fixing block fixedly mounted on the outer side of the locking sleeve, and a linkage spring on the outer side of the locking sleeve, the linkage spring having two ends... Do not connect with the linkage block and the fixed block. The locking sleeve is slidably fitted with a locking sleeve on the outside of the locking sleeve. The locking sleeve is rotatably fitted with a release sleeve on the outside of the locking sleeve. A locking frame is fixedly fitted on one side of the release sleeve. A movable rod is fixedly fitted on one side of the locking sleeve. A locking rod is slidably fitted in the locking frame. A locking groove is opened on the outside of the locking sleeve. One end of the locking rod is slidably inserted into the locking groove. A release groove is opened on the inside of the release sleeve. A release block is slidably fitted in the release groove. A locking groove is opened on the outside of the locking rod. A locking block is fitted in the locking groove. The locking block is fixedly connected to one side of the release block.

[0008] The present invention is further configured such that a side beam is fixedly connected to one side of the connecting beam, and this structural design significantly enhances the overall rigidity and load-bearing capacity of the front guard frame.

[0009] The present invention is further provided that an inclined beam is fixedly connected between the side beam and the connecting beam. This triangular support structure design greatly improves the structural stability and torsional resistance of the front guard.

[0010] The present invention is further configured such that a linkage hole is provided in the fixed block, and a linkage rod is connected to one side of the linkage block. One end of the linkage rod slides into the linkage hole. The cooperation between the linkage hole and the linkage rod provides a clear path and boundary for the movement of the linkage block, preventing the linkage components from shifting and shaking during operation.

[0011] The present invention is further configured such that a movable spring is movably sleeved on the outer side of the locking sleeve, and a thrust bearing is detachably provided on one side of the movable plate. The two ends of the movable spring are respectively connected to the thrust bearing and the locking sleeve. This elastic reset mechanism design realizes the automatic reset function and operation convenience of the front guard locking system. The continuous elastic force provided by the movable spring enables the locking sleeve to automatically return to the initial position after release, without the need for manual reset by the operator. The setting of the thrust bearing greatly reduces the frictional resistance when the movable plate rotates, making the operation easier and smoother.

[0012] The present invention is further configured such that a guide groove is provided on the outer side of the locking sleeve, and a guide block is slidably provided in the guide groove. The guide block is fixedly installed in the locking sleeve. This precise guiding structure design greatly improves the operational stability and accuracy of the front guard locking mechanism. The sliding cooperation between the guide groove and the guide block provides a strictly limited trajectory for the movement of the locking sleeve, ensuring that the locking sleeve can only move along the preset direction, effectively preventing the deflection and shaking of the locking sleeve during use.

[0013] The present invention is further configured such that a locking plate is connected to one end of the locking rod, a locking spring is connected to one side of the locking plate, and the other end of the locking spring is connected to the locking frame. The continuous tension generated by the locking spring enables the locking rod to automatically insert into the locking groove.

[0014] The present invention is further configured such that a push spring is connected to one side of the locking block, and the other end of the push spring is connected to the inner wall of the locking sleeve. This self-resetting locking mechanism design greatly enhances the deep locking effect and ease of use of the front guard frame connection structure.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a front guardrail for electric tricycles, which has the following advantages:

[0017] 1. Through a meticulously designed structural combination, including a crossbeam, connecting beam, mounting plate, detachable connection of locking sleeve and locking rod, and a linkage mechanism composed of release sleeve and release block, the problem of cumbersome front guard frame disassembly and assembly requiring multiple tools in existing technologies is completely solved. The entire disassembly and assembly process only requires a simple rotation of the release sleeve, and finally the release block drives the locking block to disengage from the locking groove, achieving rapid removal of the front guard frame without the use of any tools. This innovative linkage mechanism design eliminates the cumbersome operation of traditional bolt and nut fixing methods that require multiple professional tools such as wrenches and screwdrivers, greatly saving users' tool preparation costs. At the same time, it simplifies the operation process and reduces the difficulty of operation, allowing ordinary users without mechanical assembly skills to easily complete the disassembly and assembly of the front guard frame. Especially in emergency situations, this quick disassembly mechanism can significantly shorten the processing time, improve the user-friendliness and practicality of the product, effectively avoid problems such as thread stripping and component damage caused by improper operation in traditional connection methods, and significantly improve the maintenance convenience and emergency handling capability of electric tricycles.

[0018] 2. Through a multi-layered locking protection mechanism, including sliding limit of guide groove and guide block, rotational blocking of movable plate and movable hole, and insertion and fixing of locking rod and locking groove, the system successfully solves the problem of low stability of simple connection devices in existing technologies. The misalignment of movable hole and movable rod and the sliding limit of guide block in guide groove form the first layer of locking protection; the limit of inner wall of locking sleeve on outer wall of locking plate forms the second layer of locking protection; the locking limit formed by locking rod inserted into locking groove and locking frame forms the third layer of locking protection. This progressive multi-layered locking system can maintain the connection's firmness even under the continuous vibration and periodic impact generated by electric tricycles driving on uneven roads. It effectively prevents the connection mechanism from loosening or failing in the face of instantaneous impact forces generated by sudden road obstacles, emergency braking or collisions. It ensures that the front guard is stably installed on the electric tricycle for a long time, avoiding the safety hazard of the front guard accidentally loosening or even completely falling off during driving, protecting the personal safety of the driver and other road users, and significantly improving the safety and market competitiveness of electric tricycles.

[0028] Please see Figures 1-5 A front guardrail for an electric tricycle includes a crossbeam 1, connecting beams 2 fixedly connected to both sides of the crossbeam 1, a mounting plate 3 fixedly mounted on the inner side of the connecting beams 2, a detachable locking sleeve 4 on one side of the mounting plate 3, a detachable locking rod 5 on the inner side of the locking sleeve 4, a rotatable movable plate 6 on the outer side of the locking sleeve 4, a movable hole 7 on the movable plate 6, a linkage block 8 fixedly connected to one side of the movable plate 6, a fixing block 9 fixedly mounted on the outer side of the locking sleeve 4, and a linkage spring 10 on the outer side of the locking sleeve 4, with both ends of the linkage spring 10 connected to the linkage block 8 and the fixing block 9 respectively. The movable sleeve is provided with a locking sleeve 11. The outer side of the locking sleeve 4 is rotatably fitted with a release sleeve 12. A locking frame 13 is fixedly provided on one side of the release sleeve 12. A movable rod 14 is fixedly provided on one side of the locking sleeve 11. A locking rod 15 is slidably provided in the locking frame 13. A locking groove 16 is opened on the outer side of the locking sleeve 4. One end of the locking rod 15 is slidably inserted into the locking groove 16. A release groove 17 is opened on the inner side of the release sleeve 12. A release block 18 is slidably provided in the release groove 17. A locking groove 19 is opened on the outer side of the locking rod 5. A locking block 20 is provided in the locking groove 19. The locking block 20 is fixedly connected to one side of the release block 18.

[0029] A side beam 21 is fixedly connected to one side of the connecting beam 2.

[0030] An inclined beam 22 is fixedly connected between the side beam 21 and the connecting beam 2.

[0031] In this embodiment, when the front guard frame needs to be removed from the electric tricycle, firstly, the linkage plate is rotated forward. The linkage plate will drive the linkage hole 23 and the thrust bearing 26 installed on one side to rotate forward, and the linkage plate will drive the linkage block 8 to rotate forward. The linkage block 8 will drive the linkage rod 24 on one side to rotate forward along the linkage hole 23, and the linkage block 8 will cooperate with the fixing block 9 to compress the linkage spring 10. When the linkage spring 10 is compressed to its limit, the movable hole 7 will rotate to a position concentric with the movable rod 14. Then, the locking sleeve 11 is pushed, and the locking sleeve 11 will drive the inner guide block 28 to slide along the guide groove 27. The locking sleeve 11 will also drive the movable rod 14 on one side to gradually slide into the movable hole 7. At the same time, the locking sleeve 11 will cooperate with the thrust bearing 26 to compress the movable spring 25. Then, the locking sleeve 11 will no longer limit the outer wall of the locking plate 29. Then, the release sleeve 12 is rotated forward, and the release sleeve 12 will drive the locking rod through the locking frame 13 on one side. 15. The locking plate 29 and the locking spring 30 rotate in the forward direction, and then the inner wall of the locking groove 16 presses against one end of the locking rod 15. Due to the rounded corner structure design of one end of the locking rod 15 and the inner wall of the locking groove 16, one end of the locking rod 15 slides out of the locking groove 16, and the other end of the locking rod 15 will drive the locking spring 30 to stretch outward through the locking plate 29. At the same time, the release sleeve 12 will drive the irregularly shaped release groove 17 opened on the inner side to rotate, so that the release block 18 moves in the release groove 17. Then the release block 18 will drive the release groove 17 to slide outward, so that the release block 18 will drive the locking block 20 to move outward, so that the locking block 20 gradually disengages from the locking groove 19, and the locking block 20 will press against the push spring 31 on one side. Then the locking sleeve 4 is removed from the outside of the locking rod 5, and the locking sleeve 4 can be removed. Then, the other locking sleeves 4 are removed by referring to the above steps, so as to achieve convenient removal of the entire front guard.

[0032] Please see Figures 3-5 As a further implementation of the overall equipment: a linkage hole 23 is provided in the fixed block 9, and a linkage rod 24 is connected to one side of the linkage block 8, with one end of the linkage rod 24 sliding through the linkage hole 23.

[0033] The outer side of the locking sleeve 4 is movably fitted with a movable spring 25, and the movable plate 6 is detachably fitted with a thrust bearing 26 on one side. The two ends of the movable spring 25 are connected to the thrust bearing 26 and the locking sleeve 11, respectively.

[0034] The outer side of the locking sleeve 4 is provided with a guide groove 27, and a guide block 28 is slidably provided in the guide groove 27. The guide block 28 is fixedly installed in the locking sleeve 11.

[0035] One end of the locking rod 15 is connected to a locking plate 29, and a locking spring 30 is connected to one side of the locking plate 29. The other end of the locking spring 30 is connected to the locking frame 13.

[0036] A push spring 31 is connected to one side of the locking block 20, and the other end of the push spring 31 is connected to the inner wall of the locking sleeve 4.

[0037] More specifically, when the front guard needs to be installed on an electric tricycle, the locking rod 5 is fixedly installed in the corresponding position on the electric tricycle. Then, the front guard is placed in the corresponding position, so that the locking rod 5 passes through the reserved mounting hole on the mounting plate 3. Then, the locking sleeve 4 is fitted onto the outside of the locking rod 5 from the other side. Then, the release sleeve 12 is rotated in the opposite direction. The release sleeve 12 will drive the locking spring 30, the locking rod 15, and the locking plate 29 to rotate in the opposite direction through the locking frame 13. At the same time, the release sleeve 12 will drive the release groove 17 to rotate in the opposite direction, so that the push spring... 31. Slowly push the locking block 20 back to its original position, and the locking block 20 and the release block 18 will slide inward to reset, so that the locking block 20 is reinserted into the locking groove 19. At this time, the locking frame 13 drives the locking rod 15 and other components to rotate in the opposite direction to the position corresponding to the original locking groove 16. Then, the locking spring 30 resets and pulls the locking plate 29, so that the locking plate 29 drives the locking rod 15 to slide inward. Then, one end of the locking rod 15 will be inserted into the original locking groove 16. Then, the locking sleeve 11 is released, and the movable spring 25 pushes the locking sleeve 11 to drive the guide Block 28 slides back to its original position along guide groove 27, and locking sleeve 11 drives movable rod 14 to slide back to its original position. When movable spring 25 is fully reset, movable rod 14 no longer limits movable plate 6 through movable hole 7. Then linkage spring 10 resets and pushes linkage block 8. Linkage block 8 drives one side of movable plate 6 to rotate back to its original position, and linkage block 8 drives one side of linkage rod 24 to rotate back to its original position along linkage hole 23. Then movable plate 6 drives movable hole 7 and thrust bearing 26 to rotate back to their original positions in the opposite direction, so that movable hole 7 rotates to a position that is not corresponding to movable rod 14. Positioning, then the movable rod 14 supports the locking sleeve 11 to one side of the movable plate 6, and with the guide block 28 and guide groove 27 limiting the locking sleeve 11, the locking sleeve 11 cannot move. Then the inner wall of the locking sleeve 11 limits the outer wall of the locking plate 29, so that the locking plate 29 and the locking rod 15 cannot move outward. Then the locking rod 15 and the locking groove 16 cooperate to lock and limit the locking frame 13, so that the locking frame 13 and the release sleeve 12 cannot rotate accidentally, thereby avoiding the possibility of accidental loosening and accidental fall-off, and ensuring the stable installation of the front guard.

[0038] In summary, during the use or operation of the entire device: when it is necessary to remove the entire front guard frame from the electric tricycle, firstly, rotate the linkage plate forward. The linkage plate will drive the linkage hole 23 and the thrust bearing 26 installed on one side to rotate forward, and the linkage plate will drive the linkage block 8 to rotate forward. The linkage block 8 will drive the linkage rod 24 on one side to rotate forward along the linkage hole 23, and the linkage block 8 will cooperate with the fixed block 9 to compress the linkage spring 10. When the linkage spring 10 is compressed to its limit, the movable hole 7 will rotate to a position concentric with the movable rod 14. Then, push the locking sleeve 11. The locking sleeve 11 will drive the inner guide block 28 to slide along the guide groove 27, and the locking sleeve 11 will drive the movable rod 14 on one side to gradually slide into the movable hole 7. At the same time, the locking sleeve 11 will cooperate with the thrust bearing 26 to compress the movable spring 25. Then, the locking sleeve 11 will no longer limit the outer wall of the locking plate 29. Then, rotate the release sleeve 12 forward. The release sleeve 12 will be pulled by the locking frame 13 on one side. The locking lever 15, locking plate 29, and locking spring 30 rotate in the forward direction. Then, the inner wall of the locking groove 16 presses against one end of the locking lever 15. Due to the rounded corner design of the locking lever 15 and the inner wall of the locking groove 16, one end of the locking lever 15 slides out of the locking groove 16. The other end of the locking lever 15 will drive the locking spring 30 to stretch outward through the locking plate 29. At the same time, the release sleeve 12 will drive the irregularly shaped release groove 17 opened on the inner side to rotate, so that the release block 18 moves in the release groove 17. Then, the release block 18 will drive the release groove 17 to slide outward, so that the release block 18 will drive the locking block 20 to move outward, so that the locking block 20 gradually disengages from the locking groove 19. The locking block 20 will press against the push spring 31 on one side. Then, the locking sleeve 4 is removed from the outside of the locking lever 5, thus removing the locking sleeve 4. Then, the other locking sleeves 4 are removed by referring to the above steps, thereby realizing the convenient removal of the entire front guard.

[0039] When the front guard needs to be installed on the electric tricycle, the locking rod 5 is fixedly installed in the corresponding position on the electric tricycle. Then, the front guard is placed in the corresponding position, so that the locking rod 5 passes through the reserved mounting hole on the mounting plate 3. Then, the locking sleeve 4 is fitted onto the outside of the locking rod 5 from the other side. Then, the release sleeve 12 is rotated in the opposite direction. The release sleeve 12 will drive the locking spring 30, the locking rod 15, and the locking plate 29 to rotate in the opposite direction through the locking frame 13. At the same time, the release sleeve 12 will drive the release groove 17 to rotate in the opposite direction, so that the push spring 31 slowly... Pushing the locking block 20 to reset it, the locking block 20 and the release block 18 will slide inward to reset, allowing the locking block 20 to re-insert into the locking groove 19. At this time, the locking frame 13 will drive the locking rod 15 and other components to rotate in the opposite direction to the position corresponding to the original locking groove 16. Then, the locking spring 30 will reset and pull the locking plate 29, causing the locking plate 29 to drive the locking rod 15 to slide inward. Then, one end of the locking rod 15 will insert into the original locking groove 16. Then, the locking sleeve 11 will be released, and the movable spring 25 will push the locking sleeve 11 to drive the guide block 28. The movable rod 14 slides back to its original position along the guide groove 27, and the locking sleeve 11 drives the movable rod 14 to slide back to its original position. When the movable spring 25 is fully reset, the movable rod 14 no longer limits the movable plate 6 through the movable hole 7. Then, the linkage spring 10 resets and pushes the linkage block 8. The linkage block 8 drives one side of the movable plate 6 to rotate back to its original position, and the linkage block 8 drives one side of the linkage rod 24 to rotate back to its original position along the linkage hole 23. Then, the movable plate 6 drives the movable hole 7 and the thrust bearing 26 to rotate back to their original positions in the opposite direction, so that the movable hole 7 rotates to a position that does not correspond to the movable rod 14. Then, the movable rod 14 supports the locking sleeve 11 to one side of the movable plate 6. With the help of the guide block 28 and the guide groove 27, the locking sleeve 11 is limited, so that the locking sleeve 11 cannot move. Then, the inner wall of the locking sleeve 11 limits the outer wall of the locking plate 29, so that the locking plate 29 and the locking rod 15 cannot move outward. Then, the locking rod 15 and the locking groove 16 cooperate to lock and limit the locking frame 13, so that the locking frame 13 and the release sleeve 12 cannot rotate accidentally, thereby avoiding the possibility of accidental loosening and accidental fall-off, and ensuring the stable installation of the front guard.

[0040] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model.
