DETAILED DESCRIPTION

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0020] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0021] The utility model embodiment provides an anti-rollover mechanism for an electric tricycle. Figure 1-4 As shown, the anti-rollover mechanism of the electric tricycle includes: an assembly tube 2 fixed on the frame 1 of the electric tricycle; two pull-out assembly frames 10, both of which are slidably installed in the assembly tube 2, and both of which are provided with a detachable connecting frame 3; a mounting tube 4, which is fixedly installed on the connecting frame 3; a first spring 5 for buffering, which is arranged in the mounting tube 4; an adjustable slide bar 6, which is slidably installed in the mounting tube 4, and the bottom end of the slide bar 6 extends out of the mounting tube 4; a fixed frame 7, which is arranged on the mounting tube 4, and a mounting shell 8 is fixedly installed on the bottom of the fixed frame 7, and a guide wheel 9 is rotatably installed in the mounting shell 8; two sets of limiting mechanisms for limiting the two assembly frames 10, and the limiting mechanisms are arranged on the assembly tube 2.

[0022] It should be noted that, in the current market, most of the measures to improve the safety performance of electric tricycles focus on enhancing braking performance and strengthening the strength of the vehicle body. Although these measures have improved the safety of electric tricycles to a certain extent, their effects on the core safety issue of rollover are not significant. Rollover accidents often occur when driving at high speeds, making sharp turns or on uneven roads. Due to the special structure and center of gravity distribution of electric tricycles, once a rollover occurs, the consequences are often very serious. Although there are some advanced vehicle stability control systems on the market, such as the ESP electronic stability system, these systems can monitor the driving status of the vehicle in real time through complex sensors and control algorithms, and actively intervene in the driving trajectory of the vehicle at critical moments, thereby improving the driving stability of the vehicle to a certain extent. However, these systems are usually costly and have high requirements for the structure and control system of the vehicle, making it difficult to be widely used in mid- and low-end models such as electric tricycles. Therefore, in view of the core safety issue of rollover of electric tricycles, it is particularly important to develop an anti-rollover mechanism with a simple structure, moderate cost, and easy installation and maintenance.

[0023] In this embodiment, the arrangement of the assembly tube 2 and the pull-out assembly frame 10 enables the entire anti-rollover mechanism to be flexibly installed on the electric tricycle frame 1, which is convenient for adaptation according to different vehicle models. At the same time, the detachable connecting frame 3 enables the installation tube 4 and other components to be conveniently disassembled and replaced, thereby improving the maintenance convenience of the mechanism; secondly, the first spring 5 and the adjustable slide bar 6 in the installation tube 4 are used in combination, which can effectively absorb and disperse the roll force through the buffering effect of the spring and the sliding adjustment of the slide bar 6 when the electric tricycle rolls, thereby preventing the occurrence of rollover. This design is not only simple and effective, but also relatively low in cost, and is suitable for low- and medium-end models such as electric tricycles. Furthermore, the setting of the guide wheel 9 in the fixing frame 7 and the mounting shell 8 enables the entire mechanism to maintain a stable posture during the driving of the electric tricycle, and will not affect its anti-rollover effect due to uneven road surface or vibration. Finally, the use of two sets of limiting mechanisms can accurately limit the assembly frame 10, ensuring that it can accurately play its role when needed, and can also maintain a stable posture when not needed, avoiding interference with the normal driving of the electric tricycle.

[0024] In a further preferred embodiment of the utility model, the limiting mechanism includes: a mounting frame 11 fixed on the assembly tube 2; a pin rod 12 slidably mounted on the mounting frame 11, and the bottom end of the pin rod 12 extends into the assembly tube 2; a second spring 13 sleeved on the pin rod 12; and a limiting block 14 fixed on the bottom end of the pin rod 12 for limiting the assembly frame 10.

[0025] In this embodiment, the mounting frame 11 is fixed on the assembly tube 2, providing a stable mounting base for the pin 12, and the pin 12 can slide on the mounting frame 11. This sliding design allows the position of the pin 12 to be flexibly adjusted to meet the limit requirements in different situations; secondly, the second spring 13 is sleeved on the pin 12, which plays a role of buffering and resetting. When the assembly frame 10 is moved by external force, the pin 12 will be subjected to corresponding thrust or tension, and the second spring 13 can absorb these forces to keep the pin 12 stable; at the same time, when the external force disappears, the second spring 13 can cause the pin 12 to reset, ensuring that the limit mechanism is always in the correct position; finally, the limit block 14 is fixed at the bottom end of the pin 12, used to limit the assembly frame 10; when the assembly frame 10 moves to the preset position, the limit block 14 will contact it, thereby preventing the assembly frame 10 from moving further; this limit design can effectively prevent the assembly frame 10 from moving when it is not needed, and maintain the stability of the entire anti-rollover mechanism.

[0026] In a further preferred embodiment of the utility model, a plurality of limiting grooves 18 compatible with the limiting blocks 14 are provided on the top of the mounting frame 11, an assembly groove 19 for assembling the connecting frame 3 is provided on one side of the mounting frame 11, and a bolt 15 for limiting the connecting frame 3 is provided on the mounting frame 11, and one end of the bolt 15 is threadedly penetrated through the mounting frame 11.

[0027] In this embodiment, a plurality of limiting grooves 18 are provided on the top of the mounting frame 11, which are matched with the limiting blocks 14. This design enables the limiting blocks 14 to be embedded in the limiting grooves 18 when they are moved to a specific position, thereby realizing accurate limiting of the pin rod 12 and the assembly frame 10. The setting of the limiting grooves 18 not only enhances the stability and reliability of the limiting, but also makes the operation of the limiting mechanism more intuitive and convenient. Secondly, an assembly groove 19 for assembling the connecting frame 3 is provided on one side of the mounting frame 11. This design enables the connecting frame 3 to be easily installed on the mounting frame 11 and to form a stable connection with other components such as the assembly frame 10. The presence of the assembly groove 19 simplifies the installation process, improves the assembly efficiency, and also reduces the assembly difficulty, making the entire anti-rollover mechanism easier to install and maintain; in addition, a bolt 15 for limiting the connecting frame 3 is also provided on the mounting frame 11, and one end of the bolt 15 is threadedly penetrates the mounting frame 11. By adjusting the tightness of the bolt 15, the connecting frame 3 can be fixed and limited to ensure that it will not loosen or shift during use. This limiting method is simple and effective, which not only ensures the stability of the connecting frame 3, but also facilitates its adjustment and replacement.

[0028] In a further preferred embodiment of the utility model, a damping block 16 is arranged at the top end of the first spring 5, a threaded groove is opened on the slide rod 6, a screw rod 17 is arranged in the threaded groove, and a fixing frame 7 is fixedly installed on the bottom end of the screw rod 17.

[0029] In this embodiment, a damping block 16 is provided at the top of the first spring 5; the addition of the damping block 16 can effectively increase the damping effect of the first spring 5 when it is compressed or stretched, reduce its vibration frequency and amplitude, and thus improve the stability of the entire anti-rollover mechanism. When the electric tricycle rolls over, the damping block 16 can absorb and disperse more impact force, reduce the impact of the rollover on the vehicle, and further improve the effect of rollover protection; secondly, a threaded groove is provided on the slide bar 6, and a screw 17 is provided in the threaded groove; this design allows the length of the slide bar 6 to be precisely adjusted by adjusting the position of the screw 17; by rotating the screw 17, it can be moved up and down in the threaded groove, thereby changing the overall length of the slide bar 6. This adjustable design allows the anti-rollover mechanism to meet the needs of different vehicle models, and improves the adaptability and flexibility of the mechanism.

[0030] In a further preferred embodiment of the present invention, the assembly tube 2 is a metal square tube, and a sliding hole is opened on the top of the assembly tube 2 for the limit block 14 to pass through.

[0031] In this embodiment, the assembly tube 2 adopts the design of a metal square tube. The metal square tube has the advantages of stable structure, high strength, and wear resistance, which can ensure that the anti-rollover mechanism is not easily deformed or damaged during use. At the same time, the design of the square tube makes the cross-sectional shape of the assembly tube 2 more regular, which is conducive to the accurate installation and positioning of other components (such as the assembly frame 10, the connecting frame 3, etc.); secondly, a sliding hole is opened on the top of the assembly tube 2 for the limit block 14 to pass through. This design allows the limit block 14 to smoothly pass through the sliding hole under the drive of the pin rod 12, and accurately limit the assembly frame 10; the existence of the sliding hole not only simplifies the operation process of the limit mechanism, but also improves the accuracy and reliability of the limit.

[0032] In a further preferred embodiment of the present invention, a threaded hole is provided on the mounting frame 11 , and the threaded hole is adapted to fit the bolt 15 .

[0033] In this embodiment, threaded holes are provided on the mounting frame 11, and these threaded holes are matched with the bolts 15. This design enables the bolts 15 to be conveniently tightened or loosened, thereby achieving the fixation and position limiting of the connecting frame 3; specifically, when the connecting frame 3 needs to be installed, it is only necessary to place the connecting frame 3 between the assembly frame 10 and the mounting frame 11, and then use the bolts 15 to pass through the threaded holes of the mounting frame 11 to firmly fix the connecting frame 3 on the assembly frame 10; due to the cooperation between the threaded holes and the bolts 15, it can be ensured that the connecting frame 3 is not easy to loosen or shift when subjected to external force, thereby improving the stability of the entire anti-rollover mechanism.

[0034] In a further preferred embodiment of the utility model, reinforcing ribs are fixedly installed on the connecting frame 3, and a plurality of reinforcing rods are symmetrically fixedly installed on the bottom of the fixing frame 7, and the bottom ends of the reinforcing rods are fixedly connected to the top of the mounting shell 8.

[0035] In this embodiment, reinforcing ribs are fixedly installed on the connecting frame 3. The presence of reinforcing ribs can significantly improve the structural strength and stability of the connecting frame 3, so that it can withstand greater external forces and impact forces. During the driving process of the electric tricycle, the reinforcing ribs can effectively disperse and absorb forces from different directions, reduce the deformation and damage risks of the connecting frame 3, and thus improve the durability and reliability of the entire anti-rollover mechanism; secondly, a number of reinforcing rods are symmetrically fixedly installed at the bottom of the fixed frame 7, and the role of these reinforcing rods is to further enhance the supporting capacity and stability of the fixed frame 7. By fixing the reinforcing rods, the fixed frame 7 can better withstand the force transmitted by the slide bar 6, ensuring the stability and smoothness of the slide bar 6 during movement. At the same time, the design of the reinforcing rod can also reduce the vibration and deformation of the fixed frame 7 when it is subjected to external forces, and maintain the stability of the entire mechanism; in addition, the bottom end of the reinforcing rod is fixedly connected to the top of the mounting shell 8. This connection method enables the reinforcing rod to effectively connect the fixed frame 7 and the mounting shell 8 into a whole, forming a more stable structure.

[0036] In summary, the electric tricycle anti-rollover mechanism provided by the technical solution solves the problem of electric tricycle rollover through a simple, practical and cost-effective design, improves the safety performance of the electric tricycle, and reduces the risk of rollover accidents. Compared with existing measures such as brake performance improvement and vehicle body strength reinforcement on the market, as well as costly vehicle stability control systems, the utility model has a wider application prospect and market potential.

[0037] Compared with the related art, the flexible setting of the assembly tube 2 and the pull-out assembly frame 10 enables the mechanism to adapt to different models of electric tricycle frames 1, thereby improving the versatility and practicality of the mechanism; the design of the detachable connecting frame 3 enables key components such as the mounting tube 4 to be easily disassembled and replaced, greatly simplifying the maintenance and repair process and reducing maintenance costs; the combination of the first spring 5 and the adjustable slide bar 6 in the mounting tube 4 constitutes an effective roll force absorption and dispersion system; through the buffering effect of the spring and the length adjustment of the slide bar 6, the mechanism can respond quickly and effectively prevent rollover when the electric tricycle rolls; this design not only improves the driving safety of the electric tricycle, but also enhances the driver's confidence and comfort.
