Description

Technical Field

[0001] The present invention relates to the technical field of brakes, and in particular to a brake device for a new energy sanitation vehicle. Background Art

[0002] Against the backdrop of global advocacy of green environmental protection and sustainable development, the new energy industry is booming at an unprecedented rate. As an innovative application of new energy technology in the field of sanitation, new energy sanitation vehicles have become the main force in urban cleaning operations. Among the many key components of new energy sanitation vehicles, the brake device plays a vital role. It is the core component to ensure the safe driving of the vehicle and is directly related to the braking performance of the vehicle during driving. Therefore, the research and development and application of high-performance, advanced and reliable new energy sanitation vehicle brake devices have become the key needs and important research directions for the development of the current new energy sanitation vehicle industry.

[0003] However, when the existing new energy sanitation vehicle brake device is in use, it is not convenient to buffer the force on the brake disc during braking. The huge impact force acts on the brake disc, brake pads and components of the entire braking system, which will increase the wear of these components, thereby increasing the maintenance cost of the vehicle. Summary of the invention

[0004] The purpose of the present invention is to provide a new energy sanitation vehicle brake device. By setting a buffer component, the problem that the existing new energy sanitation vehicle brake device is not convenient for buffering the force of the brake disc during braking during use is solved. The huge impact force acts on the brake disc, brake pads and parts of the entire braking system, which will increase the wear of these parts, thereby increasing the maintenance cost of the vehicle.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The present invention is a new energy sanitation vehicle brake device, comprising a liquid storage box, on which a buffer mechanism and a power mechanism are arranged;

[0007] The buffer mechanism includes two buffer components and a transmission component, the buffer component includes a hinge block arranged on the right side of the liquid storage box, the rear side of the hinge block is hinged with two hinged rods, the rear sides of the two hinged rods are hinged with sliders, the two sliders are penetrated by sliding rods, the two sliders are slidably connected to the sliding rods, two buffer springs are sleeved on the sliding rods, and the sides of the two buffer springs close to each other are respectively fixedly connected to the two sliders, the transmission component includes an infusion pipeline connected to the right side of the liquid storage box, and the power mechanism includes a slide plate slidably connected to the inner wall of the liquid storage box.

[0008] Further, fixed blocks are fixedly connected to both the left and right sides of the sliding rod. One side of each of the two fixed blocks close to the sliding rod is fixedly connected to one of the two buffer springs respectively. An arc-shaped plate is fixedly connected to the rear sides of the two fixed blocks. A brake pad is fixedly connected to the rear side of the arc-shaped plate. A brake disc is arranged on the right side of the liquid storage box.

[0009] Further, two liquid infusion pipes II are communicated and arranged at the bottom of the liquid infusion pipe I. Cylindrical hydraulic boxes are communicated and arranged on one side of each of the two liquid infusion pipes II close to each other. Support frames are fixedly connected to the outer walls of the two cylindrical hydraulic boxes. Sealing sliders are slidably connected to the inner walls of the two support frames.

[0010] Further, hydraulic sliding rods are fixedly connected to one side of each of the two sealing sliders close to each other. One side of each of the two hydraulic sliding rods close to each other extends outside the two cylindrical hydraulic boxes respectively. The two hydraulic sliding rods are respectively slidably connected to the two cylindrical hydraulic boxes. The hydraulic sliding rod located at the front side is fixedly connected to the hinge block.

[0011] Further, two racks I are fixedly connected to the left side of the sliding plate. The left sides of the two racks I both extend outside the liquid storage box. The two racks I are both slidably connected to the liquid storage box. A support frame I is fixedly connected to the left side of the liquid storage box. A transmission rod penetrates through the support frame I. The transmission rod is slidably connected to the support frame I.

[0012] Further, a support frame II is fixedly connected to the right side of the transmission rod. Two rotating shafts penetrate through the support frame II. The two rotating shafts are respectively rotatably connected to the support frame II. Gears are fixedly connected to the outer walls of the two rotating shafts. The two gears are respectively meshed with the two racks I. Two racks II are fixedly connected to the left side of the liquid storage box. The two racks II are respectively meshed with the two gears.

[0013] The present invention has the following beneficial effects:

[0014] (1) By arranging the buffer assembly in the present invention, when the two hydraulic sliding rods approach each other, the two hinge rods rotate around their hinge axes on the hinge block, so that the two hinge rods respectively drive the two sliders to move away from each other, and the two sliders respectively squeeze the two buffer springs. The two buffer springs are squeezed and contracted to generate an increasingly large elastic force, which is transmitted to the brake pads through the fixed blocks and the arc-shaped plate, so that the two brake pads gradually clamp the brake disc to complete braking, which can prevent huge impact forces from directly acting on the brake disc, brake pads and components of the entire braking system, thereby reducing the wear degree between components, effectively extending the service life of key components such as the brake disc and brake pads, and further reducing the maintenance cost of the vehicle;

[0015] (2) By setting up a transmission component in the present invention, after the pressure is transmitted to two sealing sliders through the oil in the first infusion pipeline and the second infusion pipeline, the two sealing sliders approach each other under the limitation of two cylindrical hydraulic boxes. Thus, the two sealing sliders drive two hydraulic sliding rods to approach each other. The two hydraulic sliding rods drive two arc-shaped plates and brake pads to approach each other through two buffer components. Until the two brake pads contact the brake disc, the two hydraulic sliding rods continue to approach, thereby driving the two buffer components to squeeze the brake disc to decelerate the vehicle, enabling the mechanical energy of the skateboard to be converted into hydraulic energy. This hydraulic transmission method can push the brake pads closer to the brake disc more quickly and directly compared with other mechanical transmissions, enabling the vehicle to achieve braking in a short time, thus effectively shortening the braking distance, improving the braking performance of the vehicle, and ensuring driving safety.

[0016] (3) By setting up a power mechanism in the present invention, during braking, the transmission rod will move rightward as the brake is stepped on. Thus, the transmission rod drives the second support frame to move rightward. The second support frame drives the two rotating shafts on it to move rightward. The two rotating shafts drive the two gears to move rightward respectively. Thus, the two gears roll on the two second racks respectively, causing the two gears to rotate selflessly under the limitation of the rotating shafts. Thus, the two gears drive the first racks engaged with them to move rightward respectively. Since the two gears move rightward while rotating, the moving stroke of the two first racks will have a multiple difference from that of the transmission rod, thereby driving the skateboard on the right side of the two first racks to move rightward faster. The skateboard moves rightward to squeeze the oil in the liquid storage box, and the oil is transmitted to the buffer mechanism through hydraulic transmission to decelerate the brake disc. Through the stroke amplification mechanism, the smaller displacement of the transmission rod is converted into the larger displacement of the skateboard, thereby enhancing the response speed and force of braking and making the braking effect more remarkable.

[0017] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figures 1-7As shown in the figure, the present invention is a brake device for a new energy sanitation vehicle, which includes a liquid storage box 1 fixedly connected to the vehicle body. The liquid storage box 1 stores oil. A buffer mechanism 2 and a power mechanism 3 are arranged on the liquid storage box 1. The buffer mechanism 2 includes two buffer components 21 and a transmission component 22. The buffer component 21 includes a hinge block 211 arranged on the right side of the liquid storage box 1. Two hinge rods 212 are hinged at the rear side of the hinge block 211. This hinge design provides a flexible rotation basis for subsequent mechanical movements. Two slider blocks 213 are hinged at the rear sides of the two hinge rods 212, enabling the force to be transmitted orderly in this mechanical structure. A slide rod 214 passes through the two slider blocks 213, and the two slider blocks 213 are slidably connected to the slide rod 214. This connection form allows the slider blocks 213 to slide smoothly along the slide rod 214. Two buffer springs 215 are sleeved on the slide rod 214. The sides of the two buffer springs 215 close to each other are fixedly connected to the two slider blocks 213 respectively. When the braking action occurs, the huge impact force is first transmitted to the slider blocks 213. After being stressed, the slider blocks 213 slide along the slide rod 214. During this process, the buffer springs 215 are compressed, and the elastic potential energy generated by themselves will offset part of the impact force. Fixed blocks 216 are fixedly connected to the left and right sides of the slide rod 214 respectively. The sides of the two fixed blocks 216 close to the slide rod 214 are fixedly connected to the two buffer springs 215 respectively. Arc-shaped plates 217 are fixedly connected to the rear sides of the two fixed blocks 216. Brake pads 218 are fixedly connected to the rear sides of the arc-shaped plates 217. A brake disc 111 is arranged on the right side of the liquid storage box 1, and the brake disc 111 is connected to the wheel axle. By setting the buffer component 21, it is possible to prevent the huge impact force from directly acting on the brake disc 111, the brake pads 218 and the components of the entire braking system, thereby reducing the wear degree between components, effectively extending the service life of key components such as the brake disc 111 and the brake pads 218, and further reducing the vehicle maintenance cost.

[0030] The transmission assembly 22 includes an infusion pipeline 221 connected to the right side of the liquid storage box 1. At the bottom of the infusion pipeline 221, two infusion pipelines 222 are connected. This branch structure enables the liquid to be shunted and transmitted. On the side where the two infusion pipelines 222 are close to each other, a cylindrical hydraulic box 223 is connected. The cylindrical hydraulic box 223 is used to accommodate hydraulic oil and provide space for subsequent hydraulic transmission. On the outer walls of the two cylindrical hydraulic boxes 223, support frames 224 are fixedly connected. On the side where the two support frames 224 are away from each other, they are fixedly connected to the vehicle body. The support frames 224 play a role in supporting and fixing the cylindrical hydraulic boxes 223. Inside the walls of the two support frames 224, sealing sliders 225 are slidably connected. The sealing sliders 225 can slide flexibly within the support frames 224 and ensure the sealing performance of the cylindrical hydraulic boxes 223. On the side where the two sealing sliders 225 are close to each other, hydraulic sliding rods 226 are fixedly connected. On the side where the two hydraulic sliding rods 226 are close to each other, they respectively extend outside the two cylindrical hydraulic boxes 223. The two hydraulic sliding rods 226 are respectively slidably connected to the two cylindrical hydraulic boxes 223. The hydraulic sliding rod 226 located at the front side is fixedly connected to the hinge block 211. When the power mechanism 3 pushes the sliding plate 311 to move, the liquid in the liquid storage box 1 enters the cylindrical hydraulic box 223 through the infusion pipeline 221 and the infusion pipeline 222 under the action of pressure, pushing the sealing slider 225 and the hydraulic sliding rod 226 connected thereto to move, thereby driving the hinge block 211 to act, and finally realizing the braking operation of the brake pads 218 approaching the brake disc 111. By setting the transmission assembly 22, the mechanical energy of the sliding plate can be converted into hydraulic energy. Compared with other mechanical transmissions, this hydraulic transmission method can push the brake pads closer to the brake disc more quickly and directly, enabling the vehicle to achieve braking in a short time, effectively shortening the braking distance, improving the braking performance of the vehicle, and ensuring driving safety.

[0031] The power mechanism 3 includes a slide plate 311 slidably connected to the inner wall of the liquid storage box 1. Two first racks 312 are fixedly connected to the left side of the slide plate 311. The left sides of the two first racks 312 both extend outside the liquid storage box 1, and the two first racks 312 are both slidably connected to the liquid storage box 1. This structural design ensures that the first rack 312 can smoothly extend or retract into the liquid storage box 1 as the slide plate 311 moves. A first support frame 313 is fixedly connected to the left side of the liquid storage box 1. A transmission rod 314 passes through the first support frame 313, allowing the transmission rod 314 to perform a linear motion within the first support frame 313. The transmission rod 314 is slidably connected to the first support frame 313. A second support frame 315 is fixedly connected to the right side of the transmission rod 314. The second support frame 315 provides a basis for the installation and rotation of the rotating shaft 316 and the gear 317. Two rotating shafts 316 pass through the second support frame 315, and the two rotating shafts 316 are both rotatably connected to the second support frame 315. Gear 317 is fixedly connected to the outer walls of the two rotating shafts 316, and the two gears 317 are respectively engaged with the two first racks 312. Two second racks 318 are fixedly connected to the left side of the liquid storage box 1, and the two second racks 318 are respectively engaged with the two gears 317. When the transmission rod 314 is displaced under the action of an external driving force, it drives the second support frame 315 and the rotating shaft 316 and the gear 317 connected thereto to move. Due to the meshing relationship between the gear 317 and the first rack 312 and the second rack 318, the rotation of the gear 317 will be converted into the linear motion of the first rack 312, thereby driving the slide plate 311 to slide within the liquid storage box 1. By setting the power mechanism 3, a smaller displacement of the transmission rod is converted into a larger displacement of the slide plate through a stroke amplification mechanism, thereby enhancing the response speed and force of the brake and making the braking effect more significant.

[0032] During use, the transmission rod 314 will move to the right as the brake is depressed. Thus, the transmission rod 314 drives the second support frame 315 to move to the right. The second support frame 315 drives the two rotating shafts 316 thereon to move to the right. The two rotating shafts 316 respectively drive the two gears 317 to move to the right. Thus, the two gears 317 respectively roll on the two second racks 318, causing the two gears 317 to rotate selflessly under the limitation of the rotating shafts 316. Thus, the two gears 317 respectively drive the first racks 312 engaged therewith to move to the right. Since the two gears 317 move to the right while rotating, the moving stroke of the two first racks 312 to the right will have a multiple difference from that of the transmission rod 314. Thus, it drives the slide plates 311 on the right sides of the two first racks 312 to move to the right faster. The slide plates 311 move to the right and squeeze the oil in the liquid storage box 1. Since the oil is difficult to compress, the pressure is transmitted to the two sealing sliders 225 through the oil in the first infusion pipeline 221 and the second infusion pipeline 222, causing the two sealing sliders 225 to approach each other under the limitation of the two cylindrical hydraulic boxes 223. Thus, the two sealing sliders 225 drive the two hydraulic slide rods 226 to approach each other. The two hydraulic slide rods 226 drive the two arc-shaped plates 217 and the brake pads 218 to approach each other through the two buffer components 21. Until after the two brake pads 218 contact the brake disc 111, the two hydraulic slide rods 226 continue to approach, thus driving the two buffer components 21 to squeeze the brake disc 111 to decelerate the vehicle. The two hinge rods 212 rotate around their hinge shafts on the hinge blocks 211, thus driving the two sliders 213 to move away from each other respectively. The two sliders 213 respectively squeeze the two buffer springs 215. The two buffer springs 215 are squeezed and contracted to generate an increasingly large elastic force, which is transmitted to the brake pads 218 through the fixing blocks 216 and the arc-shaped plates 217. Thus, the two brake pads 218 gradually clamp the brake disc 111 to complete the braking.
