Description

Technical Field

[0001] This invention belongs to the field of braking technology, and particularly relates to a decoupled power-operating mechanism, a decoupled braking assembly, and a vehicle. Background Technology

[0002] Currently, the brake pedal structure used in automobiles is a lever structure, consisting of a pedal base, pedal arm, pedal pad, pivot, and CV joint base (connected to the booster pushrod). It is mounted on the front bulkhead of the driver's compartment. When the driver presses the brake pedal, the lever effect of the pedal arm amplifies the driver's force, which is then applied to the CV joint base and transmitted to the booster device for braking. However, the existing brake pedal structure has limited installation space and occupies a large area. This means the brake booster must be installed along with the brake pedal at or near the driver's foot, restricting its placement within the vehicle and preventing flexible arrangement. Furthermore, in the event of a collision, the front compartment being compressed can cause the brake booster to push backward against the brake pedal, ultimately compressing the driver's leg and causing additional injury. Summary of the Invention

[0003] In order to solve the above-mentioned technical problems, the purpose of this invention is to provide a decoupled power-operating mechanism that can decouple the pedal end and the power-operating end so that the two can be freely arranged.

[0004] To achieve the above objectives, the technical solution of the present invention is as follows: A decoupled working mechanism includes a receiving end cylinder assembly, a working end cylinder assembly, and a connecting pipe. The receiving end cylinder assembly has a first piston rod and a first interface, and the working end cylinder assembly has a second piston rod and a second interface. The two ends of the connecting pipe are respectively connected to the first interface and the second interface. The receiving end cylinder assembly, the working end cylinder assembly, and the connecting pipe together form a medium receiving area containing a fluid medium. The first piston rod is in a normally extended state relative to the receiving end cylinder assembly, and the second piston rod is in a normally retracted state relative to the working end cylinder assembly. When the first piston rod retracts relative to the receiving end cylinder assembly under the action of an external force, the fluid medium in the receiving end cylinder assembly is squeezed into the working end cylinder assembly, and finally pushes the second piston rod outward relative to the working end cylinder assembly. When the external force is removed, the first piston rod extends to its reset position, and the second piston rod retracts to its reset position.

[0005] The beneficial effects of the above-mentioned technical solution of the present invention are as follows: the working end cylinder assembly and the working end cylinder assembly are connected by a connecting pipe. When the first piston rod contracts, the second piston rod extends, and when the first piston rod extends, the second piston rod contracts. That is, the working end cylinder assembly and the working end cylinder assembly are linked. When the working end cylinder assembly is subjected to external force and does work, the corresponding working end cylinder assembly does work externally. Moreover, the positions of the working end cylinder assembly and the working end cylinder assembly can be arranged arbitrarily without interfering with each other.

[0006] Based on the above technical solution, the present invention can be further improved as follows: Furthermore, the working end cylinder assembly also includes a first cylinder and a first piston. The first piston is slidably disposed in the first cylinder. One end of the first piston rod is perpendicularly connected to one end of the first piston. The other end of the first piston rod extends and protrudes out of the first cylinder. The first interface is disposed on the first cylinder and communicates with the rodless cavity of the first cylinder. The rodless cavity of the first cylinder constitutes part of the medium receiving area.

[0007] The beneficial effect of the above-mentioned further technical solution is that when the first piston rod contracts under the action of external force, it will squeeze the first piston and force the fluid medium in the rodless chamber of the first cylinder into the working end cylinder assembly. At this time, the second piston rod of the working end cylinder assembly will extend to perform work.

[0008] Furthermore, the first cylinder body has a first through hole for the first piston rod to pass through. The first through hole is a non-circular hole, and the first piston rod is adapted to the first through hole.

[0009] The beneficial effect of the above-mentioned further technical solution is that it prevents the first piston rod from rotating relative to the first cylinder.

[0010] Furthermore, the working end cylinder assembly also includes an elastic element disposed within the first cylinder, the elastic force of which drives the first piston to move the first piston rod to extend.

[0011] The beneficial effect of the above-mentioned further technical solution is that when the external force is removed, the first piston and the first piston rod can automatically return to the extended state under the action of the elastic element. During the extension of the first piston rod, the rodless chamber of the first cylinder will draw back the fluid medium in the working end cylinder assembly, so that the second piston rod will contract synchronously.

[0012] Furthermore, the working end cylinder assembly also includes a second cylinder and a second piston. The second piston is slidably disposed in the second cylinder. One end of the second piston rod is perpendicularly connected to one end of the second piston. The other end of the second piston rod extends and protrudes out of the second cylinder. The second piston rod is used to perform external work. The second interface is disposed on the second cylinder and communicates with the rodless cavity of the second cylinder. The rodless cavity of the second cylinder constitutes part of the medium receiving area.

[0013] The beneficial effect of the above-mentioned further technical solution is that when the fluid medium of the working end cylinder assembly flows into the working end cylinder assembly, the second piston slides relative to the second cylinder to drive the second piston rod to extend to perform work.

[0014] Furthermore, the first cylinder body is provided with a first air pressure balance hole communicating with the rod chamber of the first cylinder body, and / or the second cylinder body is provided with a second air pressure balance hole communicating with the rod chamber of the second cylinder body.

[0015] The beneficial effect of the above-mentioned further technical solution is that it enables both the rod chamber of the first cylinder and the rod chamber of the second cylinder to maintain balance with the outside atmosphere, thereby avoiding pressure buildup or negative pressure in the rod chambers of the first and second cylinders, which would hinder the sliding of the first and second pistons.

[0016] Furthermore, the inner diameter of the first cylinder is smaller than the inner diameter of the second cylinder.

[0017] The beneficial effect of the above-mentioned further technical solution is that it amplifies the force exerted by the working end cylinder assembly on the external work relative to the force exerted by the receiving end cylinder assembly.

[0018] The second objective of this invention is to provide a decoupled braking assembly with a simple structure that allows the brake booster to be freely positioned relative to the brake pedal.

[0019] To achieve the above objectives, the technical solution of the present invention is as follows: a decoupled braking assembly, comprising a brake booster, a brake pedal, and a decoupled working mechanism as described above, wherein the power input end of the brake booster is connected to the second piston rod in a transmission connection, and the brake pedal is disposed on the first piston rod.

[0020] The beneficial effect of the above-mentioned technical solution of the present invention is that it allows the brake booster to be arranged arbitrarily relative to the brake pedal without being restricted by position.

[0021] Based on the above technical solution, the present invention can be further improved as follows: Furthermore, it also includes a mounting bracket, which comprises two flange rings and multiple connecting rods. The two flange rings are coaxially aligned and spaced apart along the axial direction. The multiple connecting rods are spaced apart along the circumferential direction between the two flange rings. The two ends of each connecting rod are connected to the two flange rings respectively. The two flange rings are connected to the power end cylinder assembly and the brake booster respectively. The second piston rod and the power input end of the brake booster both pass through the inner hole of the corresponding flange ring into the mounting bracket and are connected in transmission within the mounting bracket.

[0022] The beneficial effect of the above-mentioned further technical solution is that the power end cylinder assembly can be directly mounted on the brake booster via a mounting bracket, while the mounting bracket provides a range of motion for the extension and retraction of the second piston rod.

[0023] The second objective of this invention is to provide a vehicle with a simple structure that allows the brake booster to be freely positioned relative to the brake pedal.

[0024] To achieve the above objectives, the technical solution of the present invention is as follows: a vehicle, including the decoupled braking assembly as described above.

[0025] The beneficial effect of the above technical solution of the present invention is that the brake pedal and brake booster of the vehicle can be decoupled, that is, the installation position of the brake booster is not affected by the setting position of the brake pedal.

[0028] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0030] It is understood that spatial relation terms such as “below,” “under,” “below,” “below,” “above,” “above,” etc., can be used here to describe the relationship between one element or feature shown in the figure and other elements or features. It should be understood that, in addition to the orientation shown in the figure, spatial relation terms also include different orientations of the device in use and operation.

Therefore, the exemplary terms “below” and “under” can include both upper and lower orientations. Furthermore, the device may also include other orientations (e.g., rotated 90 degrees or other orientations), and the spatial descriptive terms used herein will be interpreted accordingly.

[0031] It should be noted that when one element is considered to be "connected" to another element, it can be directly connected to the other element or connected to the other element through an intermediary element. In the following embodiments, "connection" should be understood as "electrical connection," "communication connection," etc., if the connected circuits, modules, units, etc., have the transmission of electrical signals or data between them.

[0032] When used herein, the singular forms of “a,” “an,” and “the” may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms “comprising,” “including,” or “having,” etc., specify the presence of the stated feature, whole, step, operation, component, part, or combination thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof.

[0033] Example 1 like Figure 1 and Figure 2 As shown, this embodiment provides a decoupled working mechanism, including a receiving-end cylinder assembly 1, a working-end cylinder assembly 2, and a connecting pipe 3. The receiving-end cylinder assembly 1 has a first piston rod 11 and a first interface 12, and the working-end cylinder assembly 2 has a second piston rod 21 and a second interface 22. The two ends of the connecting pipe 3 are respectively connected to the first interface 12 and the second interface 22. The receiving-end cylinder assembly 1, the working-end cylinder assembly 2, and the connecting pipe 3 together form a medium-containing area for holding a fluid medium. The first piston rod 11... 1. The first piston rod 11 is in a normally extended state relative to the receiving end cylinder assembly 1, and the second piston rod 21 is in a normally retracted state relative to the working end cylinder assembly 2. Under the action of external force, the first piston rod 11 retracts relative to the receiving end cylinder assembly 1 to squeeze the fluid medium in the receiving end cylinder assembly 1 into the working end cylinder assembly 2, and finally pushes the second piston rod 21 outward relative to the working end cylinder assembly 2. When the external force is removed, the first piston rod 11 extends to the reset position, and the second piston rod 21 retracts to the reset position. This allows the receiving end cylinder assembly 1 and the working end cylinder assembly 2 to be connected via the connecting pipe 3. When the first piston rod 11 retracts relative to the receiving end cylinder assembly 1, the second piston rod 21 extends. Conversely, when the first piston rod 11 extends relative to the receiving end cylinder assembly 1, the second piston rod 21 retracts. In other words, the receiving end cylinder assembly 1 and the working end cylinder assembly 2 are linked. When the receiving end cylinder assembly 1 is subjected to external force and performs work, the working end cylinder assembly 2 performs work accordingly. Furthermore, the positions of the receiving end cylinder assembly 1 and the working end cylinder assembly 2 can be arranged arbitrarily without interfering with each other.

[0034] In this embodiment, the connecting pipe 3 can be a flexible pipe or a rigid pipe.

[0035] like Figure 1 and Figure 2As shown, in this embodiment, the working end cylinder assembly 1 further includes a first cylinder 13 and a first piston 14. The first piston 14 is slidably disposed within the first cylinder 13. One end of the first piston rod 11 is perpendicularly connected to one end of the first piston 14, and the other end of the first piston rod 11 extends and protrudes outside the first cylinder 13. The first interface 12 is disposed on the first cylinder 13 and communicates with the rodless cavity of the first cylinder 13. The rodless cavity of the first cylinder 13 constitutes part of the medium receiving area. This allows the first piston rod 11 to contract under external force, squeezing the first piston 14 and forcing the fluid medium in the rodless cavity of the first cylinder 13 into the working end cylinder assembly 2. At this time, the second piston rod 21 of the working end cylinder assembly 2 extends to perform external work.

[0036] like Figure 3 and Figure 4 As shown, in this embodiment, the first cylinder 13 has a first through hole 131 through which the first piston rod 11 passes. The first through hole 131 is a non-circular hole, and the first piston rod 11 is adapted to the first through hole 131. This prevents the first piston rod 11 from rotating relative to the first cylinder 13.

[0037] like Figure 3 and Figure 4 As shown, in this embodiment, the first through hole 131 can be a spline hole, and the first piston rod 11 is a spline rod. Of course, the first through hole 131 can also be a regular polygonal hole or an elliptical hole, and the cross-section of the first piston rod 11 (that is, the cross-section perpendicular to the length direction of the first piston rod 11) is also a regular polygonal or elliptical.

[0038] Preferably, in this embodiment, the first interface 12 is located on the first cylinder 13 at the end away from the first through hole 131.

[0039] like Figure 2 and Figure 5 As shown, in this embodiment, the working end cylinder assembly 1 further includes an elastic element 15 disposed within the first cylinder 13. The elastic force of the elastic element 15 drives the first piston 14 to move the first piston rod 11 towards extension. This allows the first piston 14 and the first piston rod 11 to automatically return to their extended state under the action of the elastic element 15 when the external force is removed. During the extension of the first piston rod 11, the rodless chamber of the first cylinder 13 draws back the fluid medium within the working end cylinder assembly 2, causing the second piston rod 21 to contract synchronously.

[0040] like Figure 2 and Figure 5As shown, in this embodiment, the elastic element 15 can be a spring. The elastic element 15 is installed in the rodless cavity of the first cylinder 13. The two ends of the elastic element 15 abut against the first cylinder 13 and the first piston 14, respectively. In this embodiment, the outer diameter of the elastic element 15 is slightly smaller than the inner diameter of the first cylinder 13.

[0041] like Figure 5 As shown, preferably, in this embodiment, the first piston 14 has a central protrusion 141 coaxially protruding at the middle of the end away from the first through hole 131. At this time, an edge annular groove 142 is formed between the periphery of the central protrusion 141 and the first cylinder 13. At this time, the corresponding end of the elastic member 15 can extend into the edge annular groove 142 and abut against the first piston 14, so that the first piston rod 11 can retract until the central protrusion 141 abuts against the corresponding end of the first cylinder 13 (at this time, the elastic member 15 is completely compressed and accommodated in the edge annular groove 142).

[0042] like Figure 1 and Figure 2 As shown, in this embodiment, the working end cylinder assembly 2 further includes a second cylinder 23 and a second piston 24. The second piston 24 is slidably disposed within the second cylinder 23. One end of the second piston rod 21 is perpendicularly connected to one end of the second piston 24, and the other end of the second piston rod 21 extends and protrudes outside the second cylinder 23. The second piston rod 21 is used to perform work externally. The second interface 22 is disposed on the second cylinder 23 and communicates with the rodless cavity of the second cylinder 23. The rodless cavity of the second cylinder 23 constitutes part of the medium receiving area. Thus, when the fluid medium of the receiving end cylinder assembly 1 flows into the working end cylinder assembly 2, the second piston 24 slides relative to the second cylinder 23 to drive the second piston rod 21 to extend and perform work externally.

[0043] In this embodiment, the rodless chamber of the second cylinder 23, the rodless chamber of the first cylinder 13, and the connecting pipe 3 together constitute the medium receiving area.

[0044] like Figure 2 As shown, in this embodiment, the second cylinder 23 has a second through hole 232 through which the second piston rod 21 passes, and the second piston rod 21 is in sealed sliding contact with the hole wall of the second through hole 232.

[0045] like Figure 2As shown, in this embodiment, the first cylinder 13 is provided with a first pressure balance hole 132 communicating with the rod chamber of the first cylinder 13, and the second cylinder 23 is provided with a second pressure balance hole 231 communicating with the rod chamber of the second cylinder 23. This ensures that both the rod chambers of the first cylinder 13 and the rod chambers of the second cylinder 23 can maintain equilibrium with the external atmosphere, thereby preventing pressure buildup or negative pressure in the rod chambers of the first cylinder 13 and the second cylinder 23, which would hinder the sliding of the first piston 14 and the second piston 24.

[0046] In this embodiment, the first air pressure balance hole 132 and the first through hole 131 are located at the same end of the first cylinder 13, and the second air pressure balance hole 231 and the second through hole 232 are located at the same end of the first cylinder 23.

[0047] like Figure 3 and Figure 4 As shown, in this embodiment, multiple first air pressure balance holes 132 and second air pressure balance holes 231 can be provided (and distributed in a dispersed manner to avoid being blocked by debris at the same time), and the hole diameter is small, so as to prevent debris from entering the first cylinder 13 and the second cylinder 23 through them.

[0048] In this embodiment, the second interface 22 is located on the second cylinder 23 at one end away from the second through hole 232.

[0049] In this embodiment, the inner diameter of the first cylinder 13 is smaller than the inner diameter of the second cylinder 23. This amplifies the force exerted by the working cylinder assembly 2 on the external surface relative to the force exerted by the receiving cylinder assembly 1, but the sliding stroke of the second piston rod 21 is shorter than that of the first piston rod 11. Specifically, in this embodiment, the inner diameter of the first cylinder 13 is R1, and the inner diameter of the second cylinder 23 is R2, so the force amplification factor k = (R2 / R1). 2 The force amplification factor is the ratio of the force exerted by the working end cylinder assembly 2 on the external environment to the external force exerted by the receiving end cylinder assembly 1.

[0050] In this embodiment, the working end cylinder assembly 1 and the power end cylinder assembly 2 are equivalent to two single-acting hydraulic cylinders. The rodless chamber and the rod chamber are existing technologies in the field of piston cylinders and will not be described in detail here.

[0051] In this embodiment, it is preferable to use a liquid as the fluid medium (specifically, it can be hydraulic oil or brake fluid).

[0052] Example 2 like Figure 6As shown, this embodiment provides a decoupled braking assembly, including a brake booster 200, a brake pedal 300, and a decoupled working mechanism 100 as described in Embodiment 1. The power input end of the brake booster 200 is tractively connected to the second piston rod 21, and the brake pedal 300 is disposed on the first piston rod 11. This allows the brake booster 200 to be arbitrarily arranged relative to the brake pedal 300 without positional limitations.

[0053] In this embodiment, the brake pedal 300 is fixedly disposed at one end of the first piston rod 11 outside the first cylinder 13. Specifically, the middle of the back side of the brake pedal 300 can be perpendicularly connected to the corresponding end of the first piston rod 11 (it can be welded). Since the first piston rod 11 does not rotate relative to the first cylinder 13, this makes the brake pedal 300 more stable.

[0054] like Figure 7 As shown, the decoupled braking assembly described in this embodiment also includes a mounting bracket 400. The mounting bracket 400 includes two flange rings 410 and multiple connecting rods 420. The two flange rings 410 are coaxially aligned and spaced apart along the axial direction. The multiple connecting rods 420 are spaced apart circumferentially between the two flange rings 410. The two ends of each connecting rod 420 are connected to the two flange rings 410 respectively. The two flange rings 410 are connected to the power-end cylinder assembly 2 and the brake booster 200 respectively. The power input ends of the second piston rod 21 and the brake booster 200 both pass through the inner holes of the corresponding flange rings 410 into the mounting bracket 400 and are connected in a transmission manner within the mounting bracket 400. In this way, the power-end cylinder assembly 2 can be directly mounted on the brake booster 200 through the mounting bracket 400, while the mounting bracket 400 provides a range of motion for the extension and retraction of the second piston rod 21.

[0055] In this embodiment, the power input end of the brake booster 200 and the second piston rod 21 can be connected by a ball cage coupling 500. The ball cage coupling 500 is existing technology and will not be described in detail here.

[0056] The brake booster 200 described in this embodiment is an existing product and will not be described in detail here. Moreover, the power input end of the brake booster 200 is also in a normally extended state. Once the external force acting on the brake pedal 300 is removed, the elastic element 15 will drive the first piston 14 to extend the first piston rod 11 to the reset state. Similarly, the power input end of the brake booster 200 will also extend to the reset state by itself and drive the second piston rod 21 to retract. This process will cause the fluid medium to flow back from the working end cylinder assembly 2 to the receiving end cylinder assembly 1.

[0057] Example 3 This embodiment provides a vehicle including the decoupled braking assembly as described in Embodiment 2. The brake pedal 300 and brake booster 200 of this vehicle can be decoupled, meaning the mounting position of the brake booster 200 is not affected by the mounting position of the brake pedal 300.

[0058] The vehicles described in this embodiment can be commercial vehicles (such as buses, trucks, or semi-trailer tractors), passenger vehicles (such as sedans, SUVs, or commercial vehicles), or agricultural machinery (such as tractors or harvesters).

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
