Description
Technical Field
[0001] The utility model relates to the technical field of bicycle brakes, in particular to a vehicle impact brake structure. Background Art
[0002] Electric bicycles are generally used for transportation by users, using batteries to drive the rear wheel drive. However, in daily life, electric bicycles can also be used for other purposes, such as using electric bicycles to tow other vehicles, so that the rear vehicle can easily follow the front vehicle. The two vehicles are usually fixed with an ordinary rope, and the front vehicle pulls the rear vehicle while moving forward. However, in this case, once the front vehicle encounters an emergency or a downhill section, simply pulling the rope poses a great safety hazard. If the front vehicle brakes suddenly, the rear vehicle will inevitably hit the front vehicle due to inertia, causing injuries. On downhill sections, the rear vehicle will also hit the front vehicle due to inertia. Therefore, how to solve the traction safety problem has always needed research. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a vehicle collision brake structure with a simple structure and safer use.
[0004] In order to solve the above problems, the present invention adopts the following technical solutions:
[0005] A vehicle brake structure includes a front vehicle fixing seat, a rear vehicle fixing seat, a brake rope assembly and a connecting rod. The front vehicle fixing seat is detachably connected to one end of the connecting rod, and the other end of the connecting rod is telescopically connected to a brake assembly. A connecting head is fixed on the brake assembly, and the connecting head is detachably connected to the rear vehicle fixing seat. The end of the brake rope assembly passes through the connecting head and is connected to the brake assembly.
[0006] A further technical solution is that the brake assembly includes an outer shell, a guide column, a movable plate and a spring. The movable plate is built into the outer shell and can be movably arranged left and right. One end of the guide column is fixed on the outer shell and the other end is fixed on the connecting head. The movable plate is penetrated by the guide column and is movably arranged on the left and right positions of the guide column. The other end of the connecting rod penetrates the outer shell and is fixedly connected to the movable plate. The spring is located on the inner side of the outer shell, and one end abuts against the movable plate and the other end abuts against the connecting head. When the connecting rod is subjected to emergency braking of the vehicle in front, the connecting rod will be pushed backward, and the push will cause the movable plate to be pushed backward as well. At this time, the spring is compressed, and the movable plate prompts the brake rope assembly to brake the rear vehicle.
[0007] A further technical solution is that the end of the brake rope assembly penetrates through the connecting head and can be movably connected to the impact brake assembly. The brake rope assembly includes a brake tube, a brake rope, and a limiting block. The brake rope is located inside the brake tube, and its end penetrates through the movable plate and the outer shell and is fixedly connected to the limiting block. The brake tube extends into the outer shell after penetrating through the connecting head and abuts against or is relatively fixed to the movable plate. A limiting bellows is fixed inside the movable plate, and the brake rope penetrates through the limiting bellows. One end of the limiting bellows abuts against or is fixed to the end of the brake tube. The setting of the limiting bellows can protect the brake rope from being damaged due to excessive friction with the movable plate. Of course, the end of the brake tube can also be directly abutted against the side end face of the movable plate, which also has the effect of braking the rear vehicle.
[0008] A further technical solution is that locking grooves are distributed on the front vehicle fixing seat, and one end of the connecting rod is locked and fixed in the locking grooves, enabling the detachable connection between the front vehicle fixing seat and the connecting rod.
[0009] A further technical solution is that a locking knob assembly is also placed on the front vehicle fixing seat. The locking knob assembly penetrates through one end of the connecting rod and the front vehicle fixing seat. The locking knob assembly consists of a locking knob and a locking nut. After the locking knob penetrates through one end of the connecting rod and the front vehicle fixing seat, its bottom is tightened with the locking nut. When disassembling, unscrew the locking nut and then take out the locking knob, so that the connecting rod and the front vehicle fixing seat can be disassembled.
[0010] A further technical solution is that a card slot is also provided on the side end of the connecting head. A lock扣组件 is detachably connected in the card slot, and a limiting sleeve is also sleeved on the lock扣组件. The rear vehicle fixing seat is locked on the limiting sleeve. The lock扣组件 can be buckled in the card slot on the connecting head, and the lock扣组件 is a conventional eccentric toggle lock扣, such as having the same structural function as that applied to the lock扣 of a scooter vertical rod. Of course, the lock扣组件 can also be other types of lock扣 parts, such as a detachable structure of a locking knob and a locking nut. The limiting sleeve is sleeved on the lock扣组件. Therefore, the limiting sleeve and the lock扣组件 are rotatably connected, and the rear vehicle fixing seat and the connecting head are also rotatably detachably connected. The setting of the limiting sleeve can also limit the brake rope assembly and prevent the brake rope assembly from swinging back and forth and being damaged.
[0011] A further technical solution is that the rear vehicle fixing seat includes a rear vehicle fixing seat main body and a buckle plate. The buckle plate is installed on the rear vehicle fixing seat main body through bolts. The rear vehicle fixing seat is detachably connected to the limiting sleeve, which is realized through the bolt fixing method between the rear vehicle fixing seat main body and the buckle plate.
[0012] A further technical solution is that the connecting head has a "匚" - shaped structure, and the limiting sleeve can be placed in the middle, which is convenient for connecting with the rear vehicle fixing seat.
[0013] The beneficial effects of the present invention are as follows: the present invention provides a vehicle collision brake structure, in which when the front vehicle brakes, the connecting rod can be telescopically connected to the inside of the collision brake assembly and maintains the same position. At this time, the collision brake assembly and the rear vehicle move forward a short distance due to inertia. While moving, the brake rope assembly can be used to perform emergency braking on the rear vehicle, which can effectively avoid accidents caused by the braking inertia of the front and rear vehicles and improve driving safety.

DETAILED DESCRIPTION
[0023] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.
[0024] See Figures 1 to 7 As shown, a vehicle brake structure includes a front vehicle fixing seat 9, a rear vehicle fixing seat 3, a brake rope assembly 4 and a connecting rod 8. The front vehicle fixing seat 9 is detachably connected to one end of the connecting rod 8, and the other end of the connecting rod 8 is telescopically connected to the brake assembly 7. A connecting head 12 is fixed on the brake assembly 7, and the connecting head 12 is detachably connected to the rear vehicle fixing seat 3. The end of the brake rope assembly 4 passes through the connecting head 12 and is connected to the brake assembly 7.
[0025] The brake assembly 7 includes a shell 71, a guide column 73, a movable plate 72 and a spring 74. The movable plate 72 is built into the shell 71 and can be movably arranged left and right. One end of the guide column 73 is fixed on the shell 71 and the other end is fixed on the connecting head 12. The movable plate 72 is penetrated by the guide column 73 and is movably arranged on the left and right positions of the guide column 73. The other end of the connecting rod 8 penetrates the shell 71 and is fixedly connected to the movable plate 72. The spring 74 is located on the inner side of the shell 71, and one end abuts against the movable plate 72 and the other end abuts against the connecting head 12. When the connecting rod 8 is subjected to the emergency brake of the front vehicle 2, the connecting rod 8 will be pushed backward, and the push will cause the movable plate 72 to be pushed backward as well. At this time, the spring 74 is compressed, and the movable plate 72 prompts the brake rope assembly 4 to brake the rear vehicle 1. After the end of the brake rope assembly 4 passes through the connecting head 12, it can be movably connected to the brake assembly 7. The brake rope assembly 4 includes a brake pipe 41, a brake rope 43 and a limit block 42. The brake rope 43 is located in the brake pipe 41, and the end thereof passes through the movable plate 72 and the outer shell 71 and is fixedly connected to the limit block 42. The brake pipe 41 extends into the outer shell 71 after passing through the connecting head 12, and is in contact with or relatively fixed to the movable plate 72. A limiting bellows 44 is fixed in the movable plate 72, and the brake rope 43 passes through the limiting bellows 44. One end of the limiting bellows 44 is in contact with or fixed to the end of the brake pipe 41. The setting of the limiting bellows 44 can protect the brake rope 43 from excessive friction on the movable plate 72 and cause damage. Of course, the end of the brake pipe 41 can also be directly in contact with the side end face of the movable plate 72, which also has the effect of braking the rear vehicle 1. The front vehicle fixing seat 9 is provided with locking grooves 10, and one end of the connecting rod 8 is locked and fixed in the locking grooves 10, so that the front vehicle fixing seat 9 and the connecting rod 8 can be detachably connected to each other. A locking knob assembly 11 is also placed on the front vehicle fixing seat 9. The locking knob assembly 11 passes through one end of the connecting rod 8 and the front vehicle fixing seat 9. The locking knob assembly 11 consists of a locking knob and a locking nut. After the locking knob passes through one end of the connecting rod 8 and the front vehicle fixing seat 9, the bottom of the locking knob is tightened with a locking nut. When disassembling, unscrew the locking nut and then take out the locking knob. In this way, the connecting rod 8 and the front vehicle fixing seat 9 can be disassembled. The side end of the connector 12 is also provided with a slot 5, in which a lock assembly 13 is detachably connected. A limiting sleeve 6 is also sleeved on the lock assembly 13, and the rear vehicle fixing seat 3 is locked on the limiting sleeve 6. The lock assembly 13 can be locked in the slot 5 on the connector 12, and the lock assembly 13 is a conventional eccentric button lock, which has the same structural function as that used on the upright lock of a scooter. Of course, the lock assembly 13 can also be other types of lock parts, such as a detachable structure of a locking knob and a locking nut. The limiting sleeve 6 is sleeved on the lock assembly 13. Therefore, the limiting sleeve 6 and the lock assembly 13 are rotatably connected, and the rear vehicle fixing seat 3 and the connector 12 are also rotatably and detachably connected. The setting of the limiting sleeve 6 can also limit the brake rope assembly 4 to prevent the brake rope assembly 4 from swinging back and forth and being damaged.The rear vehicle fixing seat 3 includes a rear vehicle fixing seat main body 31 and a buckle plate 32. The buckle plate 32 is installed on the rear vehicle fixing seat main body 31 by bolts. The rear vehicle fixing seat 3 is detachably connected to the limiting sleeve 6, which is achieved by the bolt fixing method between the rear vehicle fixing seat main body 31 and the buckle plate 32. The connecting head 12 is in a "C" - shaped structure, and the limiting sleeve 6 can be placed in the middle, which is convenient for connecting with the rear vehicle fixing seat 3.
[0026] In this embodiment, when the front vehicle 2 encounters an emergency and brakes suddenly, the front vehicle 2 stops moving forward, while the rear vehicle 1 will continue to move forward due to inertia until it hits an object or is stopped by natural resistance. Therefore, when stopping suddenly, since the connecting rod 8 is telescopically arranged in the outer shell 71, the connecting rod 8 stops, and the rear vehicle 1 together with the rear vehicle fixing seat 3, the connecting head 12 and the impact brake assembly 7 will move forward due to inertia. The connecting rod 8 together with the movable plate 72 does not move. The connecting head 12 moves forward due to inertia and pushes the spring 74 to compress. The outer shell 71 together with the guide post 73 moves forward. The outer shell 71 moving forward带动 the limiting block 42 to move forward. The end of the brake pipe 41 abuts against or is relatively fixed on the movable plate 72. On one hand, the outer shell 71 moves forward, and on the other hand, the brake pipe 41 is restricted by the movable plate 72 and cannot move. In this way, the brake rope 43 can complete the braking, and the other ends of the brake rope 43 and the brake pipe 41 are connected to the brake of the rear vehicle 1.
