Description

Technical Field

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

[0002] Electric tricycles, with their strong adaptability and relatively low price, have become an important means of transportation in people's daily lives, bringing great convenience and often used for picking up children, transporting goods, and other similar tasks. However, their small size and light weight also result in insufficient collision protection. To ensure rider safety, collision protection devices are usually installed on the vehicle body to enhance its safety.

[0003] While existing collision avoidance devices can significantly enhance the safety of electric tricycles, they still have the following drawbacks: 1. Existing anti-collision devices generally use bolts and welding to rigidly fix themselves to the front frame structure of the electric tricycle. This rigid connection makes the device and the vehicle body a near-rigid unit. When the electric tricycle suffers a frontal or side impact, most of the impact energy absorbed by the anti-collision device cannot be effectively dissipated or buffered, and will be directly transmitted to the vehicle frame without attenuation through the fixing point. This violent and instantaneous impact force transmission not only easily causes serious deformation or fracture of the front structure, but also transmits a huge amount of impact energy to the driver and passengers through the vehicle body, greatly increasing the risk of serious injury to the occupants.

[0004] 2. After absorbing the impact force, a large portion of the stored elastic potential energy or undissipated kinetic energy of the existing anti-collision device will be released rapidly. The released energy will generate an impact force that will act on the electric tricycle again, causing the electric tricycle to be subjected to multiple impacts, resulting in secondary injuries to the personnel and greatly increasing the probability of injury.

[0005] 3. The existing anti-collision device has serious safety hazards in its structural design. When subjected to a violent impact from a large vehicle such as a car, the impact force is too great, causing it to penetrate or deeply embed itself in the car's bumper, radiator grille, or lower body structure. If the impacting car fails to stop immediately, it will forcibly drag the rigidly connected electric tricycle along with it, posing an extremely serious threat to the lives of the people on the electric tricycle.

[0006] Therefore, in order to address the above problems, there is an urgent need for an anti-collision device for electric tricycles. Utility Model Content

[0007] (a) Technical problems to be solved In view of the problems existing in the prior art, this utility model provides an anti-collision device for electric tricycles to solve the technical problem of low safety of existing anti-collision devices mentioned in the background art.

[0008] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: an anti-collision device for an electric tricycle, comprising two mounting beams, two fixed frames fixedly connected between the two mounting beams, each fixed frame having a groove, a connecting plate inserted between the grooves of the two fixed frames, each fixed frame and the connecting plate having multiple through holes, the through holes of the fixed frames and the connecting plate communicating with each other, a pin inserted into the through holes of the fixed frames and the connecting plate, two crossbeams fixedly connected to the connecting plate, four fixed shells fixedly connected to the connecting plate, sliding columns slidably connected to each fixed shell, the sliding columns penetrating the crossbeams and slidably connected to them, a spring disposed within each fixed shell, vertical plates fixedly connected between adjacent sliding columns, anti-collision beams equally spaced fixedly connected between two vertical plates, a locking structure disposed between the connecting plate and the vertical plates, and a triggering structure disposed on the connecting plate.

[0009] The present invention is further configured such that the groove of the fixing frame faces the side of the anti-collision beam.

[0010] The present invention is further configured such that the locking structure includes two guide shells, the two guide shells are fixedly connected to the front side of the connecting plate, the guide shells are slidably connected to toothed plates, the guide shells are fixedly connected to fixed seats, the fixed seats are slidably connected to a wedge block, and the wedge block is in a limiting engagement with the toothed plates.

[0011] The present invention is further configured such that a fixed plate is fixedly connected to the wedge block one, a spring two is sleeved on the outer side of the wedge block one, the two ends of the spring two are fixedly connected to the fixed plate and the fixed seat respectively, and a pull ring is rotatably connected to the upper end of the wedge block one.

[0012] The present invention is further configured such that the triggering structure includes four square blocks, all four square blocks are fixed to the connecting plate, a first pin passes through an adjacent square block and the two are slidably connected, a second pin is slidably connected to the square block, the first pin is provided with a blind hole, and the second pin is located in the blind hole of the adjacent first pin.

[0013] The present invention is further configured such that the connecting plate is fixedly connected to four fixing plates, a tension spring is fixedly connected between the fixing plate and the adjacent first pin, a connector is fixedly connected between the two second pins on the upper side, and a connector is fixedly connected to the two second pins on the lower side, and the connector is fixedly connected to the first connector.

[0014] The present invention is further configured such that the connecting plate is fixedly connected to a fixing block, the fixing block is slidably connected to a sliding rod, the lower end of the sliding rod is configured as an inclined surface, the sliding rod is fixedly connected to the first connecting member, a connecting rod is fixedly connected between the two sliding columns located on the upper side, the fixing shell is provided with a through groove, the connecting rod slides in the through groove of the fixing shell, and the connecting rod is fixedly connected to a second wedge block.

[0015] (III) Beneficial Effects Compared with the prior art, this utility model provides an anti-collision device for electric tricycles, which has the following beneficial effects: 1. This utility model uses a spring to absorb the impact force generated during the impact, preventing the impact force from acting directly on the electric tricycle and causing excessive impact force on the electric tricycle, thereby improving the safety of the people on the electric tricycle.

[0016] 2. This utility model limits the adjacent tooth plates by using wedge blocks, so that the first spring cannot be reset. This avoids the force generated when the first spring resets acting on the electric tricycle again, causing the electric tricycle to be impacted by the first spring reset again, resulting in secondary impact and injury to personnel.

[0017] 3. This utility model releases the limit on the pin by pressing the inclined surface of the lower end of the sliding rod with a wedge block. Under the action of the tension spring, the pin is removed from the through hole of the fixing frame and the connecting plate, thereby causing the fixing frame to lose connection with the connecting plate and the electric tricycle to lose any connection with the connecting plate. This prevents the anti-collision beam from becoming embedded in the impact object due to excessive impact force, which would cause the impact object to drive the electric tricycle to continue moving and cause secondary injury to personnel, thus improving the safety of the electric tricycle.

[0023] Please see Figures 1-8 An anti-collision device for an electric tricycle includes two mounting beams 1, with two fixed frames 2 fixed between the two mounting beams 1. The fixed frames 2 are provided with grooves, and a connecting plate 3 is inserted between the grooves of the two fixed frames 2. Both the fixed frames 2 and the connecting plate 3 are provided with multiple through holes, and the through holes of the fixed frames 2 and the connecting plate 3 are interconnected. A pin 4 is inserted into the through holes of the fixed frames 2 and the connecting plate 3. Two crossbeams 5 are fixed to the connecting plate 3, and four fixed shells 6 are fixed to the connecting plate 3. Sliding columns 7 are slidably connected to the fixed shells 6, and the sliding columns 7 pass through the crossbeams 5 and are slidably connected to them. A spring 8 is provided inside the fixed shell 6. Vertical plates 9 are fixed between adjacent sliding columns 7, and anti-collision beams 10 are fixed between two vertical plates 9 at equal intervals. A locking structure is provided between the connecting plate 3 and the vertical plates 9, and a triggering structure is provided on the connecting plate 3. The present invention is further configured such that the groove of the fixed frame 2 faces the side of the anti-collision beam 10.

[0024] Specifically, in this embodiment, two anti-collision beams 10 are installed at the front of the electric tricycle. If the electric tricycle is hit, the anti-collision beam 10 will be hit first, and then the anti-collision beam 10 will drive the two vertical plates 9 to move backward. The two vertical plates 9 will drive the sliding column 7 to move backward. The sliding column 7 will slide along the adjacent fixed shell 6 and absorb the impact force generated during the impact through the spring 8. This prevents the impact force generated by the impact from acting directly on the electric tricycle, causing the electric tricycle to be subjected to excessive impact force, thereby improving the safety of the people on the electric tricycle.

[0025] Please see Figure 4 and Figure 6 The locking structure includes two guide shells 11, which are fixed to the front side of the connecting plate 3. The guide shells 11 are slidably connected to toothed plates 12. The guide shells 11 are fixedly connected to fixed seats 13. The fixed seats 13 are slidably connected to wedge blocks 14, which are limited to the toothed plates 12. The wedge blocks 14 are fixedly connected to fixed disks 15. Springs 16 are sleeved on the outer side of the wedge blocks 14. The two ends of the springs 16 are fixedly connected to the fixed disks 15 and the fixed seats 13, respectively. A pull ring 17 is rotatably connected to the upper end of the wedge blocks 14.

[0026] Specifically, in this embodiment, when the vertical plate 9 moves backward, the vertical plate 9 drives the toothed plate 12 to move backward. The toothed plate 12 slides backward along the adjacent guide shell 11. At the same time, the upper teeth of the toothed plate 12 engage with the wedge block 14, and under the action of the spring 16, the wedge block and the toothed plate 12 are always in contact. Under the limiting action of the toothed plate 12 and the wedge block 14, the toothed plate 12 can only move backward. Therefore, after the anti-collision beam 10 is impacted, the spring 8 is compressed. Through the limiting action of the wedge block on the adjacent toothed plate 12, the spring 8 cannot return to its original position, thus avoiding impact. When the spring 8 resets, the force generated acts on the electric tricycle again, causing the electric tricycle to be impacted again by the spring 8 reset, resulting in secondary impact and injury to the personnel. When the tension spring 21 is pulled upward, the wedge block 14 moves upward along the fixed seat 13, the spring 2 16 is compressed, the wedge block 14 releases its restriction on the toothed plate 12, and under the action of the spring 8, the vertical plate 9 and the toothed plate 12 move forward and reset. Then the pull ring 17 is released, and under the action of the spring 2 16, the wedge block 14 contacts the adjacent toothed plate 12 again.

[0027] Please see Figure 4 , Figure 7 and Figure 8The triggering structure includes four square blocks 18, all of which are fixed to the connecting plate 3. A pin 1 4 passes through adjacent square blocks 18 and is slidably connected to them. A second pin 19 is slidably connected to each square block 18. Pin 1 4 has a blind hole, and pin 2 19 is located within the blind hole of an adjacent pin 1 4. The connecting plate 3 is fixed with four fixing plates 20. A tension spring 21 is fixed between each fixing plate 20 and an adjacent pin 1 4. A connector 22 is fixed between the two upper pins 2 19. Both pins 19 on the lower side are fixed to connectors 23, which are fixed to connectors 22. A fixing block 24 is fixed to the connecting plate 3, and a sliding rod 25 is slidably connected to the fixing block 24. The lower end of the sliding rod 25 is set as an inclined surface. The sliding rod 25 is fixed to connectors 22. A connecting rod 26 is fixed between the two sliding columns 7 on the upper side. The fixing shell 6 is provided with a through groove. The connecting rod 26 slides in the through groove of the fixing shell 6. A wedge block 27 is fixed to the connecting rod 26.

[0028] Specifically, in this embodiment, when the electric tricycle is subjected to excessive impact force, the anti-collision beam 10 undergoes excessive deformation, and may even become embedded with the impacting object due to excessive impact force. After a severe impact, the two sliding pillars 7 on the upper side drive the connecting rod 26 to move backward, and the connecting rod 26 drives the wedge block to move backward. Due to the excessive impact force, the backward displacement of the sliding pillars 7 increases, and the wedge block 14 presses against the inclined surface at the lower end of the sliding rod 25. The sliding rod 25 moves upward along the fixed block 24, and the sliding rod 25 drives the connecting member 22 to move upward. The connecting member 22 drives the two connecting members 23 to move synchronously. Moving upwards, the connecting parts 22 and 23 cause the adjacent pin 19 to move upwards, removing pin 19 from the blind hole of the adjacent pin 4, releasing the limit on pin 4. Under the action of the tension spring 21, pin 4 is removed from the through hole of the fixing frame 2 and the connecting plate 3, thereby causing the fixing frame 2 to lose connection with the connecting plate 3, and thus the electric tricycle to lose any connection with the connecting plate 3. This prevents the anti-collision beam 10 from being embedded in the impact object due to excessive impact force, which would cause the impact object to drive the electric tricycle to continue moving and cause secondary injury to personnel, thus improving the safety of the electric tricycle.

[0029] 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. The scope of this utility model is defined by the appended claims and their equivalents.
