Description

Technical Field

[0001] The present invention relates to the technical field of brakes, and in particular to an active brake assembly suitable for a flatbed vehicle body. Background Art

[0002] Brakes are devices that slow down, stop, or maintain a stopped state for moving parts. They are mechanical components that stop or slow down moving parts in machinery. Current flatbed vehicles (such as four-wheeled scooters) are difficult for beginners and young children to effectively control their speed during use. They are unable to apply emergency brakes in the event of a dangerous situation, which can easily lead to falls and uncontrolled scooters, reducing the user's controllability and safety. Summary of the Invention

[0003] The purpose of the present invention is to propose an active braking assembly suitable for flatbed vehicles in order to solve the problem that some flatbed vehicles currently have difficulty in performing emergency braking operations on the vehicle body through manual intervention in the event of danger, and have poor controllability and safety.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] An active braking assembly suitable for a flatbed vehicle body includes a plate body, a front wheel group installed on one side of the lower end of the plate body, and a rear wheel group installed on the other side of the lower end of the plate body. A first braking part for braking the plate body when it touches the ground is provided in the middle part of the lower end of the plate body, and a second braking part for auxiliary braking of the rear wheel group is provided at the lower end of the plate body above the rear wheel group. An electronic control part is provided on the plate body for linkage control of the first braking part and the second braking part.

[0006] As a further description of the above technical solution:

[0007] The first braking part includes a first inclined seat integrally fixed to the lower end of the plate body, a brake pad arranged below the plate body, a second inclined seat fixed to the upper end of the brake pad, and a first cylinder body obliquely installed between the first inclined seat and the second inclined seat.

[0008] As a further description of the above technical solution:

[0009] The lower end of the plate body is located at the front and rear sides of the brake pad and is fixedly connected to side baffles. The front and rear ends of the brake pad are fixedly connected to sliding columns that pass through the side baffles. The front and rear ends of the side baffles are provided with oblique grooves corresponding to the sliding columns.

[0010] As a further description of the above technical solution:

[0011] The second braking part includes a second cylinder body installed at the lower end of the plate body and located above the rear wheel body, and a friction plate installed at the lower end of the second cylinder body and having an arc-shaped structure.

[0012] As a further description of the above technical solution:

[0013] A return spring is fixedly connected between the first inclined seat and the second inclined seat, and between the plate body and the friction plate.

[0014] As a further description of the above technical solution:

[0015] The first cylinder body and the second cylinder body are both one of an electric push rod, an electric oil cylinder or an electric pneumatic cylinder.

[0016] As a further description of the above technical solution:

[0017] The lower end of the brake pad is corrugated, and the brake pad and the friction pad are made of one of a resin-based composite material, a ceramic material or a carbon composite material.

[0018] As a further description of the above technical solution:

[0019] The electronic control unit includes a power box fixed at the lower end of the board, a battery detachably installed on the inside of the power box, a momentary switch embedded in the upper end of the board and located above the front wheel group, and solar photovoltaic strips installed on the front and rear ends of the board.

[0020] As a further description of the above technical solution:

[0021] The upper end of the plate body is fixedly connected with an elastic rubber sleeve covering the inching switch.

[0022] As a further description of the above technical solution:

[0023] The output end of the solar photovoltaic strip is electrically connected to the input end of the battery, and the first cylinder, the second cylinder, the battery and the inching switch establish a series circuit through a wire.

[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0025] In the present invention, two sets of split braking structures are arranged below the original board body, and an electronic control part of the synchronously controlled braking structure is arranged on the board body. The momentary switch is arranged above the driving direction of the board body. When emergency braking is required, the user rotates his foot to step on the momentary switch, and the first cylinder body and the second cylinder body can be energized and extended outward simultaneously. At this time, the brake pad can tilt downward to contact the ground, and the friction pad will contact the rear wheel group downward. At this time, the braking is divided into two stages. The first stage is that the overall speed drops linearly, and the second stage is that the board body is stationary on the ground. This structure can manually intervene in the emergency braking operation of the vehicle body during the movement of the vehicle body, reducing the occurrence of dangerous problems such as user falls and uncontrolled scooters, thereby improving the controllability and safety of users using the flatbed vehicle body.

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0034] See also Figure 1-5The present invention provides a technical solution: an active braking assembly suitable for a flatbed vehicle body, comprising a plate body 1, a front wheel group 101 installed on one side of the lower end of the plate body 1, and a rear wheel group 102 installed on the other side of the lower end of the plate body 1. A first braking part for braking the plate body 1 when it touches the ground is provided in the middle part of the lower end of the plate body 1, a second braking part for assisting braking of the rear wheel group 102 is provided at the lower end of the plate body 1 above the rear wheel group 102, and an electronic control part for linkage control of the first braking part and the second braking part is provided on the plate body 1.

[0035] Specifically, such as Figure 1-3 As shown, the first braking part includes a first inclined seat 103 integrally fixed at the lower end of the plate body 1, a brake pad 3 arranged below the plate body 1, a second inclined seat 301 fixed at the upper end of the brake pad 3, and a first cylinder body 2 obliquely installed between the first inclined seat 103 and the second inclined seat 301.

[0036] The lower end of the plate body 1 is located at the front and rear sides of the brake pad 3 and is fixedly connected to the side baffles 105, which can provide lateral support and protection for the brake pad 3. The front and rear ends of the brake pad 3 are fixedly connected to the sliding columns 302 that pass through the side baffles 105. The front and rear ends of the side baffles 105 are provided with inclined grooves 106 corresponding to the sliding columns 302. The setting of the sliding columns 302 and the inclined grooves 106 improves the stability of the oblique movement of the brake pad 3 between the two side baffles 105.

[0037] A return spring 4 is fixedly connected between the first inclined seat 103 and the second inclined seat 301 , which can force the first cylinder 2 and the brake pad 3 to return to their initial state with an upward elastic force after the first cylinder 2 is powered off.

[0038] The first cylinder body 2 is one of an electric push rod, an electric oil cylinder or an electric air cylinder. One of the electric push rod, electric oil cylinder or electric air cylinder can be selected as the first cylinder body 2 according to actual usage and processing and manufacturing conditions.

[0039] The lower end of the brake pad 3 is corrugated. The brake pad 3 is made of one of a resin-based composite material, a ceramic material or a carbon composite material. The brake pad 3 can be made of one of a resin-based composite material, a ceramic material or a carbon composite material according to actual usage and processing and manufacturing conditions.

[0040] Specifically, such as Figure 1-3 As shown, the second braking part includes a second cylinder body 5 installed at the lower end of the plate body 1 and located above the wheel body of the rear wheel group 102, and a friction plate 501 installed at the lower end of the second cylinder body 5 and having an arc-shaped structure. The setting of the friction plate 501 with this structure increases the contact area between the friction plate 501 and the wheel body.

[0041] A return spring 4 is fixedly connected between the plate body 1 and the friction plate 501 , which can force the second cylinder body 5 and the friction plate 501 to return to their initial state when the second cylinder body 5 is powered off.

[0042] The second cylinder body 5 is one of an electric push rod, an electric oil cylinder or an electric air cylinder. One of the electric push rod, electric oil cylinder or electric air cylinder can be selected as the second cylinder body 5 according to actual usage and processing and manufacturing conditions.

[0043] The friction plate 501 is made of one of a resin-based composite material, a ceramic material or a carbon composite material.

[0044] Specifically, such as Figure 1-5 As shown, the electronic control unit includes a power box 104 fixed at the lower end of the board body 1, a battery 6 detachably installed on the inside of the power box 104, a momentary switch 7 embedded in the upper end of the board body 1 and located above the front wheel group 101, and solar photovoltaic strips 9 installed on the front and rear ends of the board body 1. When the battery 6 is inserted into the power box 104, the battery 6 will establish a connection with the circuits of the first cylinder 2, the second cylinder 5 and the momentary switch 7.

[0045] An elastic rubber sleeve 8 covering the moment switch 7 is fixedly connected to the upper end of the plate body 1, which can seal the moment switch 7 above the plate body 1. On the one hand, it can prevent the user's foot from directly affecting the moment switch 7, and on the other hand, it can provide a sealed protection for the moment switch 7.

[0046] The output end of the solar photovoltaic strip 9 is electrically connected to the input end of the battery 6. During daily outdoor use, the external light energy can be converted into electrical energy and stored in the battery 6, thereby realizing self-charging of the battery 6. The battery 6 can also be removed from the power box 104 according to actual usage conditions to replace and charge the battery 6. The first cylinder 2, the second cylinder 5, the battery 6 and the momentary switch 7 establish a series circuit through wires. When the momentary switch 7 is pressurized, it will open, and the battery 6 will supply power to the first cylinder 2 and the second cylinder 5. The first cylinder 2 and the second cylinder 5 can then extend outward, driving the brake pad 3 and the friction plate 501 to move.

[0047] Specifically, the active braking assembly proposed by the present invention is suitable for a flatbed vehicle body. It is not only suitable for the four-wheeled scooter described in the specific implementation method, but can also be adjusted for use on other flatbed vehicles such as flatbed transport vehicles or trolleys that can be manually operated.

[0048] Working principle: When the user is in normal use, the board body 1 can move on the ground through the front wheel group 101 and the rear wheel group 102, and the user's front foot does not touch the elastic rubber sleeve 8 on the board body 1. When the user encounters a dangerous situation or needs emergency braking, the user's front foot can be rotated to a certain angle and step on the elastic rubber sleeve 8 downward. At this time, the inching switch 7 will be pressurized and turned on, and the battery 6 will power the first cylinder 2 and the second cylinder 5. The first cylinder 2 and the second cylinder 5 can extend outward, and the first cylinder 2 can drive the brake pad 3 to tilt toward the ground. At the same time, the second cylinder 5 can drive the friction plate 501 to the rear wheel When the wheel group 102 moves in the direction of the wheel body, when the brake pad 3 just touches the ground and the friction pad 501 just touches the wheel body, the speed of the entire plate body 1 will drop sharply. When the brake pad 3 is completely in contact with the inside and the friction pad 501 is completely in contact with the wheel body, the plate body 1 will stop on the ground to prevent the plate body 1 from continuing to move. When the danger is eliminated, the user's foot can be separated from the elastic sleeve 8, and the inching switch 7 will be closed after the pressure is released. The battery 6 will no longer power the first cylinder body 2 and the second cylinder body 5. At this time, the brake pad 3 and the friction pad 501 will be reset to their initial positions upward under the action of the elastic force of the return spring 4.

[0049] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
