Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to an automobile electronic hydraulic parking converter. Background Art

[0002] In current automotive braking systems, the master brake cylinder is a key component responsible for converting the driver's braking intention into actual braking force, thereby achieving vehicle deceleration or parking. Traditional master brake cylinder designs rely on mechanical transmission methods. For example, depressing the brake pedal pushes a piston, which in turn generates hydraulic or pneumatic pressure that drives the brake pads into contact with the brake disc or drum, generating friction and achieving braking.

[0003] In existing technology, the handbrake and footbrake functions typically rely on separate mechanical structures. Specifically, the handbrake is typically located inside the cockpit, requiring the user to manually pull the handbrake lever to apply braking force. In contrast, the footbrake is activated by pressing the brake pedal. While this traditional design has been effective in meeting basic braking requirements, it has gradually demonstrated some limitations in practical applications.

[0004] Many vehicles currently on the market are only equipped with a foot brake system, but lack a hand brake configuration. This means that when braking (especially when parking), the driver can only rely on the foot brake to complete the operation, which undoubtedly limits the user's operating convenience and experience to a certain extent. In order to make up for this shortcoming, many users tend to modify their vehicles and add a new brake caliper in order to increase the hand brake function. However, most of the existing hand brake modification solutions involve adding a complete braking system, which not only leads to higher modification costs, but also increases the complexity and technical difficulty of the modification.

[0005] Some vehicles also use dual braking methods of electronic handbrake and foot brake, and this method requires two brake calipers, which also increases the cost to a certain extent.

[0006] Therefore, an automotive electronic hydraulic parking converter is proposed. Utility Model Content

[0007] In view of this, the embodiments of the present invention hope to provide an automotive electronic hydraulic parking switch to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial option.

[0008] The technical solution of the embodiment of the utility model is implemented as follows: an automotive electronic hydraulic parking switch, including a drive mechanism, a base and a brake plate:

[0009] The base is clamped on the driving mechanism, and the brake plate and the base are connected by fixing bolts;

[0010] A second groove is formed inside the brake plate, and a brake member is embedded in the second groove, and a transmission member is connected to the inner thread of the brake member;

[0011] One end of the transmission member passes through the base and is engaged with the output shaft of the driving mechanism. When driven by the driving mechanism, the transmission member rotates and the brake member moves linearly.

[0012] An oil inlet hole is provided on one side of the outer portion of the brake plate, and an oil outlet hole is provided on the other side;

[0013] The brake member includes a baffle and a piston, a gap exists between the piston and the second groove, and the oil inlet hole and the oil outlet hole are both connected to the gap;

[0014] A first channel is formed on the outer side of the piston, a second channel is formed on the bottom of the piston, the first channel is connected to the second channel, and an oil seal is provided on the outer side of the piston;

[0015] The first channel is located on the upper part of the oil seal and is connected to the oil inlet hole, and the second channel is connected to the oil outlet hole;

[0016] The baffle is provided with a fourth threaded hole which is threadedly connected to the transmission member.

[0017] In some embodiments: the driving mechanism includes a collar, the base includes a connecting portion and a protruding portion, and the protruding portion is inserted into the collar.

[0018] In some embodiments, the connecting portion is provided with two third threaded holes, the collar is provided with two first threaded holes, and two bolts are provided between the connecting portion and the collar and are threadedly connected in the third threaded holes and the first threaded holes.

[0020] In some embodiments, four second through holes are formed on the lower surface of the brake plate, the first through holes are connected to the second through holes, and the radius of the second through holes is greater than the radius of the first through holes.

[0021] In some embodiments, the transmission member includes a connector clamped with the first threaded hole, a partition fixed on the connector, and a screw fixed on the partition, wherein the screw is threadedly connected in the fourth threaded hole.

[0022] In some embodiments: a first groove is defined in the base, and a gasket set is disposed in the first groove.

[0023] The embodiment of the present invention has the following advantages due to the adoption of the above technical solution:

[0024] 1. This converter successfully integrates the handbrake function into the existing foot brake system, eliminating the need for a separate parking system. This not only meets the user's comprehensive needs for vehicle braking functions, but also avoids high modification costs and complicated modification processes.

[0025] 2. The card connection design between the transmission part and the drive mechanism, as well as the mechanism in which the transmission part rotates to drive the brake part to move linearly, realizes the precise transmission and efficient conversion of braking force. This design not only improves the response speed and braking efficiency of the braking system, but also ensures the stability and reliability of braking.

[0026] Third, the design of the oil inlet and outlet holes on the brake plate, as well as the gap between the piston and the second groove, allows the hydraulic oil to flow smoothly during braking, achieving even distribution of braking force.

Those skilled in the art can understand the specific meanings of the above terms in this utility model based on the specification and drawings in combination with specific circumstances.

[0041] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0042] like Figure 1-6 As shown, the embodiment of the present utility model provides 1. an automotive electronic hydraulic parking switch, comprising a drive mechanism 1, a base 2 and a brake plate 3:

[0043] The base 2 is clamped on the driving mechanism 1, and the brake plate 3 and the base 2 are connected by fixing bolts 4;

[0044] A second groove 31 is formed inside the brake plate 3, and a brake member 311 is embedded in the second groove 31. The transmission member 32 is connected to the inner thread of the brake member 311.

[0045] One end of the transmission member 32 passes through the base 2 and is engaged with the output shaft 12 of the driving mechanism 1. Under the drive of the driving mechanism 1, the transmission member 32 rotates and the brake member 311 moves linearly.

[0046] An oil inlet hole 35 is formed on one side of the outer portion of the brake plate 3, and an oil outlet hole 36 is formed on the other side;

[0047] The brake member 311 includes a baffle 3111 and a piston 3112. There is a gap between the piston 3112 and the second groove 31, and the oil inlet hole 35 and the oil outlet hole 36 are both connected to the gap.

[0048] A first channel 3114 is defined on the outside of the piston 3112 , and a second channel 3116 is defined at the bottom of the piston 3112 . The first channel 3114 and the second channel 3116 are in communication. An oil seal 3115 is provided on the outside of the piston 3112 .

[0049] The first channel 3114 is located above the oil seal 3115 and communicates with the oil inlet hole 35 , and the second channel 3116 communicates with the oil outlet hole 36 ;

[0050] The baffle 3111 is provided with a fourth threaded hole 3113 which is threadedly connected to 32;

[0051] On the basis of the above, the converter is installed on the brake cylinder, and the oil inlet hole 35 is connected to the handbrake. When the handbrake is pulled, the piston 3112 moves upward, and the oil seal 3115 blocks the communication between the oil inlet hole 35 and the first channel 3114. At the same time, the piston 3112 moves upward until the first channel 3114 is located below the oil seal 3115. The hydraulic oil is squeezed into the oil outlet hole 36, thereby driving the original foot brake caliper to move, completing the braking operation and realizing the separation of the hand brake and foot brake.

[0052] That is, when you step on the brake, the master brake cylinder pushes the hydraulic oil into this converter, and then into the brake caliper to complete the braking.

[0053] Based on the above solution, this converter only needs one brake caliper, and can complete braking regardless of whether it uses a handbrake or the original foot brake;

[0054] Furthermore, the converter can be connected to the vehicle's existing electronic handbrake driver (driving mechanism 1), and can also directly control the caliper of the existing foot brake to complete braking, thereby reducing costs.

[0055] The driving mechanism 1 also includes a driving motor, a driving pulley connected to the driving motor, and a driven pulley connected to the driving pulley through a belt, wherein the driven pulley drives the output shaft 12 to rotate. Figure 1 and Figure 2 It can be seen that the output shaft 12 is inserted into the transmission member 32 and can drive the transmission member 32 to rotate;

[0056] During actual operation, this device is installed on the brake cylinder, and the driving mechanism drives the output shaft 12 to rotate, transmitting the transmission part 32. Under the action of the threaded force, the piston 3112 moves upward, driving the caliper of the original foot brake to move and complete the braking work. In this way, the technical effect of the electronic handbrake is achieved.

[0057] In this embodiment: when the handbrake is pulled, the hydraulic oil pressure is 90-120 kg. The above pressure is only one implementation method of this embodiment. In specific practical applications, the stroke distance of the piston 3112 can be changed by preset to change the oil pressure.

[0058] In this embodiment, specifically: the driving mechanism 1 includes a ring 11, the base 2 includes a connecting portion 21 and a protruding portion 22, the protruding portion 22 is inserted into the ring 11, the connecting portion 21 is provided with two third threaded holes 212, and the ring 11 is provided with two first threaded holes 111, and there are two bolts between the connecting portion 21 and the ring 11 that are threadedly connected in the third threaded holes 212 and the first threaded holes 111. Through the above settings, the base 2 can be connected to the driving mechanism 1.

[0059] In this embodiment, specifically: four first through holes 33 are opened on the upper surface of the brake plate 3, four second threaded holes 211 are opened on the surface of the connecting part 21, and the fixing bolts 4 are threadedly connected in the second threaded holes 211 and the first through holes 33. Through the above settings, the brake plate 3 can be connected to the base 2.

[0060] In this embodiment, specifically: four second through holes 34 are opened on the lower surface of the brake plate 3, the first through hole 33 and the second through hole 34 are connected, and the radius of the second through hole 34 is larger than the radius of the first through hole 33. Through the above setting, the second through hole 34 is used to cover the nut part of the fixing bolt 4.

[0061] In this embodiment, specifically: the transmission member 32 includes a connecting member 323 engaged with the first threaded hole 111, a partition 322 fixed on the connecting member 323, and a screw 321 fixed on the partition 322, and the screw 321 is threadedly connected in the fourth threaded hole 3113;

[0062] Through the above arrangement, a stable connection between the transmission member 32 and the drive mechanism 1 and the brake plate 3 can be ensured, and sufficient strength and precision are provided to achieve accurate transmission.

[0063] In this embodiment, specifically: a first groove 23 is opened in the base 2, and a gasket group 24 is arranged in the first groove 23, such as Figure 3 As shown, the shim assembly 24 includes two upper and lower shims and a flat bearing located between the two shims. This helps reduce friction and wear between the base 2 and the transmission member 32, thereby improving the durability and reliability of the entire parking switch. Shim assembly 24 also provides additional cushioning and shock absorption, helping to optimize braking comfort.

[0064] In actual application, when the vehicle stops, by pulling the handbrake, the piston 3112 moves upward, and the oil seal 3115 blocks the communication between the oil inlet hole 35 and the first channel 3114. At the same time, the piston 3112 moves upward until the first channel 3114 is located below the oil seal 3115. The hydraulic oil is squeezed into the oil outlet hole 36, thereby driving the caliper of the original foot brake to move and complete the braking work.

[0065] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope of protection of the claims.
