Description

Technical Field

[0001] The present invention relates to the technical field of automotive parts, and particularly to an automotive electronic hydraulic parking converter. Background Art

[0002] In the current automotive braking system, the master brake cylinder, as a key component, is mainly responsible for converting the driver's braking intention into actual braking force to achieve the deceleration or stop control of the vehicle. Most traditional master brake cylinder designs rely on mechanical transmission methods, such as stepping on the brake pedal to push the piston, thereby generating hydraulic or pneumatic pressure to drive the brake pads to contact the brake discs or brake drums to generate frictional force and achieve the braking effect.

[0003] In the existing technical system, the functions of the handbrake and the footbrake are usually realized by relying on their respective independent mechanical structures. Specifically, the handbrake device is generally installed inside the cockpit, and the user needs to manually pull the handbrake lever to apply braking force; relatively speaking, the footbrake triggers the braking mechanism by stepping on the brake pedal. Although this traditional design has played a certain role in meeting the basic braking requirements, some limitations have gradually emerged in actual application scenarios.

[0004] Many vehicles currently on the market are only equipped with a footbrake system and lack a handbrake configuration. This means that during braking operations (especially when parking), the driver can only rely on the footbrake to complete, which undoubtedly limits the operation convenience and experience of users to a certain extent. To make up for this deficiency, many users tend to modify their vehicles by adding a new brake caliper in order to add the handbrake function. However, most existing handbrake modification solutions involve adding a complete set of braking systems, which not only results in a high modification cost, but also increases the complexity and technical difficulty of the modification.

[0005] There are also some vehicles that use an electronic handbrake and a footbrake for dual-mode braking, 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. Summary of the Invention

[0007] In view of this, the embodiments of the present invention hope to provide an automotive electronic hydraulic parking converter 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 embodiments of the present invention is implemented as follows: An automotive electronic hydraulic parking converter includes a driving mechanism, a base, and a brake plate:

[0009] The base is snap-fitted onto the driving mechanism, and the brake plate and the base are connected by fixing bolts;

[0010] The interior of the brake plate is provided with a second groove, and a brake member is embedded in the second groove. A transmission member is threadedly connected inside the brake member;

[0011] Wherein, one end of the transmission member penetrates through the base and is clamped with the output shaft of the driving mechanism. Under the drive of the driving mechanism, the transmission member rotates self - rotatably and the brake member moves linearly;

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

[0013] The brake member includes a baffle plate and a piston. There is a gap between the piston and the second groove. Both the oil inlet hole and the oil outlet hole communicate with the gap;

[0014] A first channel is provided on the outer side of the piston, and a second channel is provided at the bottom of the piston. The first channel communicates with the second channel. An oil seal is sleeved on the outer side of the piston;

[0015] The first channel is located above the oil seal and communicates with the oil inlet hole. The second channel communicates with the oil outlet hole;

[0016] A fourth threaded hole for threaded connection with the transmission member is provided on the baffle plate.

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

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

[0019] In some embodiments: Four first through - holes are provided on the upper surface of the brake plate, and four second threaded holes are provided on the surface of the connecting portion. The fixing bolts are threadedly connected in the second threaded holes and the first through - holes.

[0020] In some embodiments: Four second through - holes are provided on the lower surface of the brake plate. The first through - holes and the second through - holes communicate, 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 connecting piece clamped with the first threaded hole, a partition fixed on the connecting piece, and a screw rod fixed on the partition. The screw rod is threadedly connected in the fourth threaded hole.

[0022] In some embodiments: A first groove is provided in the base, and a gasket group is provided in the first groove.

[0023] Due to the adoption of the above technical solutions in the embodiments of the present invention, it has the following advantages:

[0024] First, this converter successfully integrates the handbrake function into the existing foot brake system without adding a new independent parking system, which not only meets the user's comprehensive requirements for vehicle braking functions but also avoids high modification costs and complex modification processes.

[0025] Second, the snap-fit design of the transmission part and the drive mechanism, as well as the mechanism where the rotation of the transmission part drives the linear movement of the brake part, achieve 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 hole and oil outlet hole on the brake plate, as well as the gap connection between the piston and the second groove, enable the hydraulic oil to flow smoothly during braking, achieving uniform distribution of braking force. At the same time, the design of the first channel and the second channel on the piston, as well as the blocking effect of the oil seal, further optimize the hydraulic transmission effect and improve the braking performance.

[0027] Fourth, this converter can be easily installed on the brake caliper and seamlessly docked with the original foot brake system. At the same time, by adjusting the connection method of the oil inlet hole and the oil outlet hole, the separation function of the handbrake and the foot brake can be flexibly achieved to meet the braking requirements of different vehicle models and users.

[0028] Fifth, this converter only requires one brake caliper. Whether using the handbrake or the original foot brake, braking can be completed. Moreover, by using this converter, it can be connected to the original electronic handbrake driver (drive mechanism) of the vehicle, or directly control the caliper of the original foot brake to complete braking, reducing costs.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood in combination with the drawings of the specification and specific circumstances.

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

[0042] As Figure 1-6 shown, the embodiments of the present invention provide 1. An automotive electronic hydraulic parking converter, including a driving mechanism 1, a base 2, and a brake plate 3:

[0043] The base 2 is snap-fitted 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 braking member 311 is embedded in the second groove 31. A transmission member 32 is threadedly connected inside the braking member 311;

[0045] One end of the transmission member 32 penetrates through the base 2 and is snap-fitted with the output shaft 12 of the driving mechanism 1. Under the drive of the driving mechanism 1, the transmission member 32 rotates self, and the braking member 311 moves linearly;

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

[0047] The braking member 311 includes a baffle 3111 and a piston 3112. There is a gap between the piston 3112 and the second groove 31. Both the oil inlet hole 35 and the oil outlet hole 36 communicate with the gap;

[0048] A first channel 3114 is formed on the outer side of the piston 3112, and a second channel 3116 is formed at the bottom of the piston 3112. The first channel 3114 communicates with the second channel 3116. An oil seal 3115 is sleeved on the outer side 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] A fourth threaded hole 3113 for threaded connection with 32 is formed on the baffle 3111;

[0051] On the basis described above, this converter is installed on the brake caliper. The oil inlet hole 35 is connected to the handbrake. When the handbrake is pulled, the piston 3112 moves upward. The oil seal 3115 prevents the oil inlet hole 35 from communicating with the first channel 3114. At the same time, as the piston 3112 moves upward, when 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, completing the braking work, and realizing the separation function of the handbrake and the foot brake.

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

[0053] On the basis of the above solution, only one brake caliper is required for this converter. Whether the handbrake or the original foot brake is used, braking can be completed.

[0054] Moreover, by using this converter, it can be connected to the original electronic handbrake driver (drive mechanism 1) of the vehicle, or directly control the caliper of the original foot brake to complete braking, reducing costs.

[0055] The drive mechanism 1 further includes a drive motor, a driving pulley connected to the drive motor, and a driven pulley connected to the driving pulley through a belt. Among them, the driven pulley drives the output shaft 12 to rotate. From 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 caliper. The drive mechanism drives the output shaft 12 to rotate, driving the transmission member 32. Under the action of the thread force, the piston 3112 moves upward, driving the caliper of the original foot brake to move, completing 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 between 90 and 120 kilograms. The above pressure is only one implementation method of this embodiment. In specific actual applications, the stroke distance of the piston 3112 can be changed by presetting to change the oil pressure.

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

[0059] In this embodiment, specifically: Four first through-holes 33 are formed in the upper surface of the brake plate 3, and four second threaded holes 211 are formed in the surface of the connecting portion 21. 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 formed in the lower surface of the brake plate 3. The first through-holes 33 and the second through-holes 34 are communicated, and the radius of the second through-holes 34 is greater than that of the first through-holes 33. Through the above settings, the second through-holes 34 are used to cover the nut portions of the fixing bolts 4.

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

[0062] Through the above settings, it can ensure the stable connection between the transmission member 32 and the driving mechanism 1 and the brake plate 3, and also provide sufficient strength and precision to achieve precise transmission.

[0063] In this embodiment, specifically: A first groove 23 is formed in the base 2, and a gasket group 24 is arranged in the first groove 23. As Figure 3 shown, the gasket group 24 includes two gaskets located up and down and a plain bearing located between the two gaskets, which can help reduce the friction and wear between the base 2 and the transmission member 32, and improve the durability and reliability of the entire parking converter. At the same time, the gasket group 24 can also provide additional buffering and shock absorption effects, which helps to optimize the comfort during the braking process.

[0064] During 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, when 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 completing the braking work.

[0065] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of various changes or substitutions, and these should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
