Description

Technical Field

[0001] The utility model relates to the field of brake master cylinders, in particular to a brake master cylinder fixing structure. Background Art

[0002] The master brake cylinder is usually made of aluminum alloy or steel. The outer shell is usually cast, and the interior includes one or more pistons and piston seals. The master brake cylinder is a key component in the car's braking system, responsible for converting the driver's brake pedal force into hydraulic pressure to drive the braking system.

[0003] Most of the existing brake master cylinders have a hole in the head of the pump body, and then the bolt can be slid into the hole. Then the bolt can be turned into the interior of the vehicle body using a hexagonal wrench or other tool to fix it. In this way, the brake master cylinder can be clamped and fixed on the vehicle, completing the fixed installation of the brake master cylinder.

[0004] In the above technology, although the brake master cylinder can be clamped and fixed inside the vehicle body by bolts, the structure inside the vehicle body is relatively tight and stable. During disassembly and installation, the positioning and rotation of the bolts are relatively complicated, and tools such as hex wrenches will be blocked by other parts of the vehicle body, making it difficult to disassemble and install the brake master cylinder. Therefore, a brake master cylinder fixing structure is proposed to solve the above problem. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1-Figure 3 The utility model provides an embodiment: a brake master cylinder fixing structure, including a pump body 1, which is the main part of the brake master cylinder. The lower end side of the pump body 1 is fixedly connected with an oil tank 2, and the oil tank 2 is connected to the pump body 1. The upper end of the pump body 1 is internally slidably connected with a connecting block 3, and the connecting block 3 can support and fix the upper end of the pump body 1 so that the brake master cylinder can be fixed inside the vehicle body. A connecting hole 5 is opened in the middle of the connecting block 3, and the connecting hole 5 can be connected with a bolt so that the bolt clamps and fixes the connecting block 3 inside the vehicle body. A clamping block 8 is internally slidably connected with the connecting block 3, and the clamping block 8 can be clamped by the pump body 1 so that the pump body 1 is relatively fixed relative to the clamping block 8. The outer side of the clamping block 8 is slidably connected to the upper end of the pump body 1, and the side end of the clamping block 8 is fixedly connected with a positioning block 9, and the positioning block 9 limits the clamping block 8 to slide horizontally only within a fixed distance relative to the connecting block 3, and the outer side of the positioning block 9 is slidably connected to the inside of the connecting block 3, and the connecting block 3 limits the positioning block 9 from completely sliding out of the inside of the connecting block 3.

[0031] Reference Figure 2-Figure 3The lower side end of the block 8 contacts with a ramp block 13. The ramp block 13 is squeezed to make the blocks 8 at both ends slide into the upper end of the pump body 1 to quickly install and fix the pump body 1. The outer side of the ramp block 13 is slidably connected to the lower end of the connecting block 3. The lower part of the ramp block 13 is fixedly connected with an extrusion block 12. The extrusion block 12 can drive the ramp block 13 to slide up and squeeze the blocks 8 at both ends. The outer side of the extrusion block 12 is slidably connected to the lower end of the connecting block 3. The interior of the connecting block 3 is fixedly connected with a magnet 14. The magnet 14 adsorption can make the blocks 8 at both ends slide into the interior of the connecting block 3, so that the pump body 1 can be quickly replaced. The lower end of the connecting block 3 The upper part of the U-shaped block 11 is slidably connected to the upper part, and the T-shaped block 10 limits the U-shaped block 11 to slide horizontally and linearly within a fixed distance. The lower part of the T-shaped block 10 is fixedly connected to the U-shaped block 11. By sliding the U-shaped block 11, the extrusion block 12 is no longer squeezed and can slide down, so that the limit of the pump body 1 can be released. The upper part of the U-shaped block 11 is in contact with the lower part of the extrusion block 12. The U-shaped block 11 can be clamped and fixed by bolts to maintain the stability of the overall device. When disassembling, it is only necessary to loosen the bolts without repeatedly turning the disassembly and assembly bolts, which increases the simplicity of disassembly and installation. The side end of the connecting block 3 is fixedly connected to the outside with a positioning component.

[0032] Reference Figure 1-Figure 3 The positioning component includes a block 4, which can make the distance between the connecting blocks 3 at both ends relatively fixed, so as to facilitate the positioning and installation of the connecting blocks 3. The side ends of the block 4 are fixedly connected to the sides of the connecting blocks 3, and the outside of the block 4 is slidably connected to the upper end of the pump body 1. The pump body 1 can be positioned by the block 4 and the slider 7 so that its installation angle is fixed. The side ends of the block 4 are fixedly connected with a positioning ring 6, which can support the blocks 4 at both ends and keep the position of the pump body 1 fixed. The inside of the positioning ring 6 is fixedly connected with a slider 7, and the outside of the positioning ring 6 and the slider 7 are slidably connected to the upper end of the pump body 1.

[0033] Working principle: During installation, the bolts can be slid into the inside of the connecting hole 5 so that the connecting block 3 can be installed on the vehicle body. Then, the upper end of the pump body 1 can be slid into the inside of the positioning ring 6 by sliding upward. At this time, the positioning ring 6 and the slider 7 slide into the inside of the pump body 1 so that the pump body 1 is installed and positioned. At this time, the connecting block 3 slides into the inside of both ends of the pump body 1 to keep the pump body 1 fixed. The U-shaped block 11 is slid horizontally to drive the T-shaped block 10 to slide horizontally and linearly. The U-shaped block 11 squeezes the squeezing block 12 so that the squeezing block 12 slides upward. The squeezing block 12 slides upward to squeeze the inclined block 13 at the upper end to slide upward. The inclined block 13 slides up to squeeze the blocks 8 at both ends to slide into the interior of the pump body 1 so that the connecting block 3 is fixed relative to the pump body 1. At this time, the bolts are turned so that the U-shaped block 11 can be clamped to complete the installation. When the brake master cylinder needs to be disassembled, the bolts can be loosened with a hexagonal wrench, and then the U-shaped block 11 is slid horizontally to both ends to make the extrusion block 12 and the inclined block 13 slide down. At this time, the magnet 14 absorbs the blocks 8 at both ends to slide into the interior of the connecting block 3. At this time, the pump body 1 can be disassembled by sliding down, and there is no need to disassemble and position the bolts, which increases the ease of operation.
