Description

Technical Field

[0001] This utility model belongs to the field of automotive auxiliary equipment technology, and specifically relates to an auxiliary venting device for automotive brake fluid hydraulic pipeline. Background Technology

[0002] In the current process of automobile research and development, production and maintenance, it is necessary to add brake fluid to the brake fluid lines. During the addition, the air in the lines needs to be bleed. Therefore, it is necessary to continuously press the pedal to bleed the air in the brake fluid lines. At the same time, brake fluid needs to be added continuously during the bleed process to ensure the brake fluid level and to remove the air from the brake fluid lines.

[0003] The existing brake fluid filling method requires one worker to continuously press the brake pedal inside the vehicle, while another worker outside the vehicle continuously adds brake fluid to the brake fluid lines. The two workers need to work together to continuously expel the air from the brake fluid lines and add the appropriate amount of brake fluid. Therefore, the filling process requires two workers to complete, which increases labor costs and consequently raises maintenance and manufacturing costs.

[0004] Therefore, there is a need for a venting device that can assist workers in adding brake fluid, thereby reducing the need for manual labor. Utility Model Content

[0005] To address the aforementioned problems, this utility model proposes an auxiliary bleed device for automotive brake fluid hydraulic lines, comprising at least one triangular structure. The triangular structure includes a first telescopic sleeve, a second telescopic sleeve, and a third telescopic sleeve connected end to end in sequence. A fifth telescopic sleeve is provided on the second telescopic sleeve, and an actuating part is installed on the fifth telescopic sleeve.

[0006] Preferably, the exhaust device includes two symmetrically placed triangular structures, the corners of the two triangular structures are connected by a fourth telescopic sleeve, a fifth telescopic sleeve is installed between the two triangular structures, and the fifth telescopic sleeve is located between two adjacent fourth telescopic sleeves.

[0007] Preferably, the first telescopic sleeve, the second telescopic sleeve, the third telescopic sleeve, the fourth telescopic sleeve, and the fifth telescopic sleeve each include two sleeves, and the two sleeves are slidably connected.

[0008] Preferably, a locking sleeve is provided at the connection between the two sleeves.

[0009] Preferably, pads are provided at the corners of the triangular structure.

[0010] Preferably, the gasket is made of a flexible material.

[0012] Preferably, the actuating part includes a connecting sleeve, a pressure plate, and an electric cylinder. The connecting sleeve is fixedly connected to the fifth telescopic sleeve. The electric cylinder is fixedly installed in the connecting sleeve, and the telescopic rod of the electric cylinder is fixedly connected to the pressure plate, which is located at the end of the connecting sleeve.

[0013] Preferably, the execution part further includes a control center, which includes a power supply, a signal receiving device, a processor, and a drive device. The power supply, signal receiving device, and drive device are all electrically connected to the processor, and the drive device is electrically connected to the electric cylinder.

[0014] Preferably, the processor is a microcontroller.

[0015] The beneficial effects of this utility model are:

[0016] 1. This utility model achieves the fixation of the auxiliary bleed device for the automotive brake fluid hydraulic pipeline by adjusting the lengths of the first, second, and third telescopic sleeves so that the three vertices of the triangular structure contact the lower surfaces of the vehicle's front compartment, vehicle floor, and main frame seat, respectively. Workers need to continuously add brake fluid to the brake fluid pipeline from outside the vehicle and perform certain tasks to depress the brake pedal; this saves labor costs and improves work efficiency.

[0017] 2. This utility model provides pads at all three vertices of the triangular structure to prevent the triangular structure from scratching the vehicle interior.

[0018] 3. The execution part of this utility model includes a connecting sleeve, a pressure plate, and an electric cylinder. The connecting sleeve is fixedly connected to the electric cylinder, and the electric cylinder is installed in the connecting sleeve. The telescopic rod of the electric cylinder is fixedly connected to the pressure plate. The pressure plate is located at the end of the connecting sleeve.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] refer to Figure 1An auxiliary bleed device for automotive brake fluid hydraulic lines includes at least one triangular structure. The triangular structure comprises a first telescopic sleeve 11, a second telescopic sleeve 12, and a third telescopic sleeve 13 connected end-to-end. A fifth telescopic sleeve 32 is mounted on the second telescopic sleeve 12, and an actuator 20 is installed on the fifth telescopic sleeve 32. By adjusting the lengths of the first telescopic sleeve 11, the second telescopic sleeve 12, and the third telescopic sleeve 13, the three vertices of the triangular structure contact the vehicle's front compartment 51, the vehicle floor 53, and the main frame seat 54, respectively, thus fixing the auxiliary bleed device for automotive brake fluid hydraulic lines. By activating the actuator 20, the brake pedal 52 is depressed, improving work efficiency and saving labor costs.

[0031] In the above embodiments, another optional implementation is that the triangular structure adopts a triangular frame composed of three telescopic hollow cylindrical tubes (i.e., the first telescopic sleeve 11, the second telescopic sleeve 12, and the third telescopic sleeve 13). This structure has the advantages of low mass and easy transport. By adjusting the length of the telescopic hollow cylindrical tubes (i.e., the first telescopic sleeve 11, the second telescopic sleeve 12, and the third telescopic sleeve 13), the entire device can be quickly fixed in the limited space of the driver's side area, thereby realizing the rapid fixing of the automotive brake fluid hydraulic line auxiliary exhaust device to the driver's compartment. The first telescopic sleeve 11, the second telescopic sleeve 12, the third telescopic sleeve 13, the fourth telescopic sleeve 31, and the fifth telescopic sleeve 32 each include two sleeves, which are slidably connected. Specifically, one of the two sleeves is a thicker sleeve, and the other is a thinner sleeve, with the thinner sleeve slidably installed within the thicker sleeve.

[0032] Furthermore, a locking sleeve 41 is provided at the connection between the two sleeves. Specifically, after adjusting the length of the hollow cylindrical tube (first telescopic sleeve 11, second telescopic sleeve 12, third telescopic sleeve 13, fourth telescopic sleeve 31 or fifth telescopic sleeve 32), the locking sleeve 41 in the middle of the pipe is rotated to lock the hollow cylindrical tube (first telescopic sleeve 11, second telescopic sleeve 12, third telescopic sleeve 13, fourth telescopic sleeve 31 or fifth telescopic sleeve 32) at the most appropriate length, so that it can no longer extend or retract.

[0033] Furthermore, the invention includes two symmetrically placed triangular structures, with their corners connected by a fourth telescopic sleeve 31. A fifth telescopic sleeve 32 is installed between the two triangular structures, positioned between two adjacent fourth telescopic sleeves 31. By using two triangular structures connected by the fourth and fifth telescopic sleeves 31, the distance between the two triangular structures can be adjusted. The use of two triangular structures also provides the invention with greater stability, preventing it from tipping over.

[0034] In the above embodiments, another optional implementation includes three triangular structures. Each triangular structure comprises a first telescopic sleeve 11, a second telescopic sleeve 12, and a third telescopic sleeve 13 connected end-to-end. The triangular structure is a triangular frame composed of three telescopic hollow square tubes (i.e., the first telescopic sleeve 11, the second telescopic sleeve 12, and the third telescopic sleeve 13), which has the advantages of small weight and easy handling. By adjusting the length of the telescopic hollow square tubes (i.e., the first telescopic sleeve 11, the second telescopic sleeve 12, and the third telescopic sleeve 13), the entire device can be quickly fixed in the limited space of the driver's side area, thereby realizing the rapid fixing of the automotive brake fluid hydraulic line auxiliary exhaust device to the driver's compartment. The first telescopic sleeve 11, the second telescopic sleeve 12, the third telescopic sleeve 13, the fourth telescopic sleeve 31, and the fifth telescopic sleeve 32 each include two sleeves, which are slidably connected. Specifically, one of the two sleeves is a thicker sleeve, and the other is a thinner sleeve, with the thinner sleeve slidably installed within the thicker sleeve. The corners of two adjacent symmetrically placed triangular structures are connected by a fourth telescopic sleeve 31, and a fifth telescopic sleeve 32 is installed between the two triangular structures. The fifth telescopic sleeve 32 is located between the adjacent fourth telescopic sleeves 31.

[0035] Furthermore, a locking sleeve 41 is provided at the connection between the two sleeves. Specifically, after adjusting the length of the square hollow tube (first telescopic sleeve 11, second telescopic sleeve 12, third telescopic sleeve 13, fourth telescopic sleeve 31 and fifth telescopic sleeve 32), the locking sleeve 41 in the middle of the pipe is rotated to lock the square hollow tube (first telescopic sleeve 11, second telescopic sleeve 12, third telescopic sleeve 13, fourth telescopic sleeve 31 or fifth telescopic sleeve 32) at the most appropriate length, so that it can no longer extend or retract.

[0036] Specifically, by setting up three triangular structures, which are connected by a fourth telescopic sleeve 31 and a fifth telescopic sleeve 32, the distance between the three triangular structures can be adjusted. At the same time, the use of three triangular structures makes this utility model more stable.

[0037] refer to Figure 1 The triangular structure has pads 14 at its corners. Specifically, each of the three vertices of the triangular structure has a soft pad 14 to prevent damage to the vehicle's interior.

[0038] Furthermore, the gasket 14 is made of flexible materials, including sponge, cotton, cloth, etc. The gasket 14 made of sponge is low in cost and can prevent the corners of the auxiliary exhaust equipment of the car's brake fluid hydraulic lines from scratching the car's interior, thereby protecting the car's interior.

[0039] Furthermore, the gasket 14 is made of an elastic material, including rubber, polyurethane elastomer, etc. The rubber gasket 14 has good toughness and can prevent the corners of the auxiliary exhaust device of the brake fluid hydraulic line from scratching the car interior, thereby protecting the car interior.

[0040] refer to Figure 2 The execution part 20 includes a connecting sleeve 21, a pressure plate 22, and an electric cylinder 23. The connecting sleeve 21 is fixedly connected to the fifth telescopic sleeve 32. The electric cylinder 23 is fixedly installed in the connecting sleeve 21, and the telescopic rod of the electric cylinder 23 is fixedly connected to the pressure plate 22, which is located at the end of the connecting sleeve 21. Specifically, the cylinder body of the electric cylinder 23 is fixedly installed inside the connecting sleeve 21, and the piston rod end of the electric cylinder 23 is fixedly connected to the pressure plate 22. The pressure plate 22 contacts the brake pedal 52. When the electric cylinder 23 extends, it drives the pressure plate 22 to press down the brake pedal 52, thus completing the braking action. When the electric cylinder 23 retracts, it drives the pressure plate 22 to retract, at which point the brake pedal 52 pops up without pressure, realizing the automatic pedal depressing action.

[0041] Furthermore, the execution section 20 also includes a control center 24, which includes a power supply, a signal receiving device, a processor, and a drive device. The power supply, signal receiving device, and drive device are all electrically connected to the processor, and the drive device is electrically connected to the electric cylinder 23. The processor is a microcontroller, including STM32, 51 microcontroller, AVR microcontroller, and PIC microcontroller, etc.

[0042] Specifically, staff, in conjunction with the exhaust function of the automotive engineering development diagnostic tool, use a remote control outside the vehicle to send a command to our exhaust equipment indicating the number of times the brake pedal needs to be pressed. After receiving the command, the signal receiving device transmits it to the STM32. Upon receiving the command, the STM32 issues an execution command, which is then sent to the drive unit. The drive unit drives the electric cylinder 23, which in turn drives the pressure plate 22 to press down the brake pedal 52. At the start and end of the pressing action, a buzzer connected to the STM32 emits a prompt sound. With this interactive information, staff can know the working status of the equipment at any time.

[0043] refer to Figure 3The device is manually secured on the driver's side through the following steps: First, place the auxiliary bleed device for the automotive brake fluid hydraulic line between the vehicle's front compartment 51 and the main frame seat 54. Adjust the lengths of the fourth telescopic sleeve 31 and the fifth telescopic sleeve 32 and adjust the position of the auxiliary bleed device for the automotive brake fluid hydraulic line so that the actuator 20 is directly opposite the brake pedal 52. Then, adjust the lengths of the first telescopic sleeve 11, the second telescopic sleeve 12, and the third telescopic sleeve 13 so that the three vertices of the triangular structure contact the vehicle's front compartment 51, the vehicle floor 53, and the main frame seat 54 respectively, thus securing the auxiliary bleed device for the automotive brake fluid hydraulic line.

[0044] Working principle: When using this utility model, first place it between the vehicle's front compartment 51 and the main frame seat 54. Adjust the lengths of the fourth telescopic sleeve 31 and the fifth telescopic sleeve 32 and adjust the position of the auxiliary bleed device for the vehicle's brake fluid hydraulic line so that the actuator 20 is directly facing the brake pedal 52. Then, adjust the lengths of the first telescopic sleeve 11, the second telescopic sleeve 12, and the third telescopic sleeve 13 so that the three vertices of the triangular structure contact the vehicle's front compartment 51, the vehicle floor 53, and the main frame seat 54 respectively to fix the auxiliary bleed device for the vehicle's brake fluid hydraulic line.

[0045] Staff, in coordination with the exhaust function of the automotive engineering diagnostic tool, use a remote control outside the vehicle to send a command to our exhaust equipment indicating the number of times the brake pedal needs to be pressed. The signal receiver receives the command and transmits it to the STM32. The STM32 then issues an execution command, which is sent to the drive unit. The drive unit drives the electric cylinder 23, which in turn drives the pressure plate 22 to depress the brake pedal 52. A buzzer connected to the STM32 emits a warning sound at the start and end of the pressing action. This interactive information allows staff to monitor the equipment's operating status at any time, enabling one person to complete brake fluid changes and bleed the brakes, improving work efficiency and saving labor costs.
