Description

Technical Field

[0001] This utility model relates to the field of shock absorption structure technology for tricycles, specifically a damping electronic disc brake shock absorption system for heavy-duty electric tricycles. Background Technology

[0002] Currently, the front fork shock absorption systems of tricycles, including electric tricycles and freight tricycles, generally adopt a fixed preloaded coil spring structure. Their working principle is to absorb road impacts through the elastic deformation of the spring, improving ride smoothness. However, this traditional design has the following technical drawbacks: First, spring aging leads to a decrease in elasticity. After long-term use, the spring gradually loses its elasticity due to metal fatigue, resulting in a decline in shock absorption performance, increased vehicle bumps, and impact on riding comfort and safety. The current solution is usually to replace the spring directly, but this increases maintenance costs.

[0003] Secondly, it cannot adapt to different load requirements. The fixed preload spring may be too stiff when unloaded, affecting comfort; while under heavy load, it may not provide enough support, causing the fork to bottom out and accelerating spring damage.

[0004] Currently, some tricycles on the market have optimized their front fork designs. For example, the combination of hydraulic damping and springs improves the shock absorption effect, but cannot compensate for the elastic loss of the spring itself. Another example is the adjustable damping front fork, which improves the rebound speed by adjusting the damping oil circuit, but has no direct impact on the spring stiffness. Utility Model Content

[0005] The purpose of this invention is to provide a damping electronic disc brake shock absorption system for heavy-duty electric tricycles to solve the problems mentioned in the background art.

A limiting block is sleeved on the surface of the support rod. A support spring sleeved on the support rod is engaged between the limiting block and the support beam. A damping mechanism is hinged between the support beam and the fixed base. An inner groove is opened inside the support rod. A connecting groove communicating with the inner groove is symmetrically opened on the surface of the support rod. An adjustment mechanism is provided inside the connecting groove.

[0007] In a further embodiment, the adjusting mechanism includes a connecting block that is slidably connected to the inner groove, an adjusting bolt that is threadedly connected to the connecting block is rotatably connected inside the inner groove, the lug of the connecting block passes through the connecting groove to the outside of the support rod and is fixedly connected to the limiting block, and one end of the adjusting bolt passes through the outside of the support rod and is fixedly sleeved with a rotating block.

[0008] In a further embodiment, a protective cover is fitted between the two support beams, the protective cover being used in conjunction with the tire.

[0009] In a further embodiment, one side of the tire is equipped with a hydraulic disc brake system, and the other side of the tire is equipped with an electronic disc brake system.

[0011] In a further embodiment, a sealing groove is provided inside the connecting groove, and a sealing plate that is slidably connected to the sealing groove is fixedly sleeved on the ear surface of the connecting block.

[0012] In a further embodiment, one end of the support rod extends through to the top of the fixed base and is threaded with a limit nut.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This utility model features an inner groove inside the support rod, with an adjustment mechanism designed inside the groove. This mechanism allows adjustment of the position of a limiting block on the surface of the support rod. When the limiting block is adjusted to its position on the support rod, the distance between the limiting block and the support beam can be adjusted. This allows for adjustment of the pressure exerted by the limiting block and the support beam on the support spring.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] This embodiment discloses a damping electronic disc brake shock absorption system for a heavy-duty electric tricycle, including a fixed base 1 and support beams 2 symmetrically arranged at the bottom of the fixed base 1. A tire 3 is fitted between the two support beams 2. Figure 1 , Figure 2 and Figure 4 As shown in this application, the mounting base 1 is used for the installation of the entire shock absorption system and the tire 3. There are two support beams 2, which are designed to be aligned at the bottom of the mounting base 1 for fixing the tire 3. The tire 3 is designed between the two support beams 2, and the two ends of the tire 3 shaft are respectively locked in the bottom openings of the two support beams 2. The part protruding from the bottom opening is tightened with a nut.

[0018] Preferably, a protective cover 11 is fitted between the two support beams 2. The protective cover 11 is used in conjunction with the tire 3. A hydraulic disc brake system 12 is fitted on one side of the tire 3, and an electronic disc brake system 13 is fitted on the other side of the tire 3. A connecting beam 14 is fitted on the top of the mounting base 1. The connecting beam 14 is used in conjunction with the handlebars. Figure 1 and Figure 2 As shown in this application, the protective cover 11 is designed on the top of the tire 3 to block mud and water splashed out by the tire 3. The protective cover 11 is designed between two support beams 2, and the protective cover 11 and the support beams 2 are bolted together with screws and nuts. The hydraulic disc brake system 12 is installed on one side of the tire 3. The hydraulic disc brake system 12 is mainly a mechanical braking part installed at the wheel. The mechanical braking part of the hydraulic disc brake system 12 mainly includes a brake disc fixedly connected to the tire 3, a brake caliper installed on the support beam 2, and brake pads installed inside the brake caliper. The brake caliper of the mechanical braking part 2 has a hydraulic oil pipe connector for installing an external hydraulic oil pipe. In this application, the electronic disc brake system 13 is designed on the other side of the tire 3 and is also used to brake the vehicle tire 3. It is a braking system controlled by an electrical signal, which combines the physical structure of the traditional hydraulic disc brake with electronic control technology. It uses a motor to drive a mechanical structure, such as a steel wire pull cable or push rod, to clamp the brake pads, achieving a more precise and intelligent braking effect. This is existing technology and will not be described in detail in this application. The connecting beam 14 is designed on the top of the fixed seat 1 and is used to connect the external handlebar.

[0019] More specifically, the bottom of the fixed base 1 is symmetrically provided with support rods 4 that slide and engage with the support beam 2. A limiting block 5 is sleeved on the surface of the support rod 4. A support spring 6, sleeved with the support rod 4, engages between the limiting block 5 and the support beam 2. A damping 7 is hinged between the support beam 2 and the fixed base 1. An inner groove 8 is formed inside the support rod 4. A connecting groove 9, communicating with the inner groove 8, is symmetrically formed on the surface of the support rod 4. An adjusting mechanism 10 is provided inside the connecting groove 9. One end of the support rod 4 extends through to the top of the fixed base 1 and is threadedly connected to a limiting nut 17. Figure 1 and Figure 2 As shown in this application, the support rod 4 is used to connect the fixed seat 1 and the support beam 2. The bottom of the support rod 4 has a step, and the support rod 4 slides upward from the slot of the support beam 2. The step and the support beam 2 are locked together. The support rod 4 is inserted from the bottom of the fixed seat 1, and the step at the top of the support rod 4 passes through the slot of the fixed seat 1 to the top of the fixed seat 1. Then, the limit nut 17 is tightened to fix one end of the support rod 4 to the fixed seat 1. The limit block 5 is sleeved on the surface of the support rod 4 to limit and fix one end of the support spring 6. The other end of the support spring 6 is locked on the support beam 2. The limit block 5 and the support beam 2 can limit the support spring 6 on the support rod 4. When the vehicle is bumped, the fixed seat 1 moves downward, causing the support rod 4 to move downward. The support rod 4 can support the support beam 2. The beam 2 slides downwards, with the support spring 6 providing elastic support. The damper 7 controls the rebound speed of the support spring 6 to prevent repeated bouncing caused by the support spring 6. The support spring 6 is designed on the surface of the support rod 4 to provide elastic support. The inner groove 8 is designed inside the support rod 4, and the inner groove 8 has an adjustment mechanism 10. The limit block 5 can be connected to the adjustment mechanism 10 through the connecting groove 9. Under the action of the adjustment mechanism 10, the limit block 5 can be adjusted to its position on the support rod 4, thereby adjusting the distance between it and the support beam 2, and thus adjusting the preload on the support spring 6. When the spring ages and softens, the preload can be increased to restore the support force and extend its service life. When unloaded, the preload can be reduced to improve comfort, and when heavily loaded, the preload can be increased to prevent bottoming out and improve overall practicality.

[0020] Furthermore, the adjusting mechanism 10 includes a connecting block 101 slidably connected to the inner groove 8. An adjusting bolt 102, threadedly connected to the connecting block 101, is rotatably connected inside the inner groove 8. The lug of the connecting block 101 passes through the connecting groove 9 to the outside of the support rod 4 and is fixedly connected to the limiting block 5. One end of the adjusting bolt 102 passes through the outside of the support rod 4 and is fixedly sleeved with a rotating block. A sealing groove 15 is provided inside the connecting groove 9. A sealing plate 16, slidably connected to the sealing groove 15, is fixedly sleeved on the surface of the lug of the connecting block 101. Figure 3As shown in this application, the adjusting bolt 102 is rotatably connected to the inner groove 8. One end of the adjusting bolt 102 extends through the outside of the support rod 4 and is fixedly sleeved with a rotating block. The rotating block allows for easy rotation of the adjusting bolt 102. The connecting block 101 is located inside the inner groove 8 and is slidably connected to the inner groove 8. The lug of the connecting block 101 is slidably connected to the connecting groove 9. The connecting block 101 is threadedly connected to the adjusting bolt 102. When the adjusting bolt 102 is rotated, the connecting block 101 can be driven to move up and down reciprocally. Since the lug of the connecting block 101 is fixedly connected to the limiting block 5, the limiting block 5 is driven by the connecting block 101 to move up and down reciprocally. A sealing groove 15 is provided inside the connecting groove 9. A sealing plate 16 is installed on the lug of the connecting block 101. The sealing plate 16, together with the sealing groove 15, can seal the connecting groove 9 to prevent external dust and impurities from entering the inner groove 8.

[0021] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
