Description

Technical Field

[0001] The utility model relates to an adjusting bolt for an electronic parking brake system. Background Art

[0002] The traditional parking brake system is a manual cable type, which is not convenient to use when in use. Therefore, an electronic parking brake system has been gradually developed. The existing Chinese patent with the application number 202123285822.3 discloses an AGV electronic parking brake structure, including an electric push rod fixed on a vehicle frame. A push rod support plate is arranged below the electric push rod. One end of a hexagon head bolt coaxial with and facing the electric push rod is also connected to the vehicle frame. A handbrake pull plate is slidably connected to the hexagon head bolt. The output end of the electric push rod is connected to a push rod front support assembly. A connecting plate is fixed on the back of the push rod front support assembly. The connecting plate is fixed to the output end of the electric push rod by bolts. One end of a brake cable assembly is connected to both sides of the push rod front support assembly. One end of the brake cable of the brake cable assembly is connected to the handbrake pull plate. The electric push rod is connected with a stroke control mechanism.

[0003] When the above-mentioned proposed electronic parking brake system is in use, its handbrake pull plate is only simply connected to the hexagon head bolt, and the simple hexagon head bolt does not have the effect of finely adjusting the position of the handbrake pull plate. Therefore, when the brake wears after the parking system has been used for a certain period of time, the tightness of the brake cable cannot be finely adjusted by adjusting the position of the handbrake pull plate. Therefore, in order to solve the above technical defects, we propose an adjusting bolt for an electronic parking brake system. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the defects existing in the prior art, and to propose an adjusting bolt for an electronic parking brake system.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An adjusting bolt for an electronic parking brake system, including a mounting bolt. An installation cylinder is sleeved on one end of the mounting bolt rod body close to the bolt head. A locking nut is installed at one end of the installation cylinder close to the bolt head through threads. An adjusting area is arranged at one end of the outer ring surface of the installation cylinder away from the locking nut. A pair of main grooves are arranged on the upper side inside the adjusting area. Two fine-tuning plates are placed in the adjusting area through the main grooves. A clamping groove for clamping the end of the brake cable is arranged at one end of the fine-tuning plate away from the installation cylinder. A plurality of semi-circular adjusting pieces are arranged on both sides of the fine-tuning plate inside the adjusting area.

[0007] Preferably, auxiliary grooves are symmetrically arranged on one side of the adjusting area away from the main grooves. The inner sides of both ends of the adjusting piece are respectively clamped in the main groove and the auxiliary groove.

[0008] Preferably, a washer is sleeved on one end of the adjustment area close to the locking nut, and matching clamping protrusions are provided on the inner side of the washer corresponding to the main groove and the auxiliary groove.

[0009] Preferably, one side of the outer ring surface of the washer is provided with scale lines, and the outer ring surface of the locking nut is provided with matching indicator arrows corresponding to the scale lines.

[0010] Preferably, two magnetic strips are symmetrically installed inside the adjustment area through the installation groove, and one side of the magnetic strip is in contact with the adjustment sheet and the fine-tuning plate.

[0011] Preferably, the end surfaces at both ends of the installation tube are provided with anti-slip grooves, and the inner wall of the adjustment area of the installation tube is a smooth surface.

[0012] Preferably, the thickness of the regulating plate is 2 mm, and the outer surface of the regulating plate is a smooth surface.

[0013] The utility model provides an adjusting bolt for an electronic parking brake system, which has the following beneficial effects:

[0014] 1: In the present invention, when the position of the fine-tuning plate needs to be adjusted due to the wear of the brake pads, the locking nut can be loosened to allow a gap between the adjusting plates, so that the personnel can easily remove the fine-tuning plate and easily move each adjusting plate, that is, the spacing between the fine-tuning plate and the locking nut is adjusted by moving the adjusting plate, thereby achieving the effect of adjusting the position of the fine-tuning plate, and the tightness of the brake line can be adjusted as appropriate according to the wear of the external brake pads, thereby avoiding the brake being too loose or too tight, and because the fine-tuning plate and the adjusting plate are symmetrically arranged on both sides of the mounting tube, the personnel can adjust the two fine-tuning plates to different spacings as appropriate according to the specific usage conditions, that is, further improving the adaptability of the present solution when used. Therefore, under the mutual cooperation of the above-mentioned components, the adjusting bolt with the function of adjusting the position of the handbrake pull plate proposed in the present solution is compared with the hexagonal head bolt with the simple installation of the handbrake pull plate in the traditional solution. The present solution is adaptable when used, which is convenient for personnel to adjust the tightness of the brake line in a targeted manner, so as to ensure the normal use of the brake pad when parking.

[0015] 2: The setting of the secondary groove in the present utility model enables two pairs of grooves to be symmetrically arranged up and down in the adjustment area. Furthermore, with the combined cooperation of the main groove and the secondary groove, the adjustment piece can only move within the adjustment area and cannot detach from the adjustment area by itself. As a result, when a person adjusts the position of the fine-tuning plate, it is more convenient. The setting of the washer enables the locking nut not to directly contact the adjustment piece when rotating, thereby avoiding the phenomenon of damage to the adjustment piece caused by the rotation of the locking nut. The setting of the scale lines and the indicating arrow enables a person to conveniently judge whether the locking nut is tightened when tightening the locking nut, and whether the locking nut is loose during long-term use. The setting of the clamping protrusion enables the washer not to rotate randomly during use, making it easier to cooperate between the scale lines and the indicating arrow.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0023] Embodiment 1

[0024] Refer to Figures 1-5, An adjusting bolt for an electronic parking brake system, including an installation bolt 1. One end of the rod body of the installation bolt 1 near the bolt head is sleeved with an installation cylinder 2. One end of the installation cylinder 2 near the bolt head is threadedly installed with a locking nut 3. One end of the outer ring surface of the installation cylinder 2 away from the locking nut 3 is provided with an adjustment area. On the upper side inside the adjustment area, there are a pair of main grooves 4. Inside the adjustment area, two fine-tuning plates 5 are placed through the main grooves 4. One end of the fine-tuning plate 5 away from the installation cylinder 2 is provided with a clamping groove for clamping the end of the brake wire. Inside the adjustment area and on both sides of the fine-tuning plate 5, there are several semi-circular adjusting pieces 6.

[0025] Embodiment 2

[0026] Refer to Figures 1-5 , In the case where other parts are the same as those in Embodiment 1, the difference between this embodiment and Embodiment 1 lies in:

[0027] On one side of the adjustment area away from the main groove 4, there are symmetrically arranged auxiliary grooves 7. The inner sides of both ends of the adjusting piece 6 are respectively clamped in the main groove 4 and the auxiliary groove 7. One end of the adjustment area near the locking nut 3 is sleeved with a washer 8. The inner side of the washer 8 is provided with clamping protrusions corresponding to the main groove 4 and the auxiliary groove 7. One side of the outer ring surface of the washer 8 is provided with scale lines. The outer ring surface of the locking nut 3 is provided with a corresponding indicating arrow 9 for the scale lines. The setting of the auxiliary groove 7 makes it so that there are two pairs of grooves symmetrically arranged up and down in the adjustment area. Furthermore, under the common cooperation of the main groove 4 and the auxiliary groove 7, the adjusting piece 6 can only move within the adjustment area and cannot break away from the adjustment area by itself. Thus, when a person adjusts the position of the fine-tuning plate 5, it is more convenient. And the setting of the washer 8 makes it so that when the locking nut 3 rotates, it will not directly contact the adjusting piece 6, thereby avoiding the phenomenon of damage to the adjusting piece 6 when the locking nut 3 rotates. The setting of the scale lines and the indicating arrow 9 enables a person to conveniently judge whether it is tightened when tightening the locking nut 3, and whether the locking nut 3 is loose during long-term use. The setting of the clamping protrusions makes it so that the washer 8 will not rotate randomly during use, thus making it easier to cooperate between the scale lines and the indicating arrow 9.

[0028] Inside the adjustment area, two magnetic attraction strips 10 are symmetrically installed through installation grooves. One side of the magnetic attraction strip 10 is attached to the adjusting piece 6 and the fine-tuning plate 5. The setting of the magnetic attraction strip 10 makes the installation cylinder 2 have a certain degree of magnetic attraction effect on the fine-tuning plate 5, that is, when installing and adjusting the position of the fine-tuning plate 5, it is not easy to break away from the installation cylinder 2 by itself, thereby improving the convenience of personnel operation; anti-slip patterns 11 are provided on both end faces of the installation cylinder 2. The inner wall of the adjustment area of the installation cylinder 2 is a smooth surface. The setting of the anti-slip patterns 11 makes it more firm and not easy to loosen when the installation bolt 1 fixes the installation cylinder 2; the thickness of the adjusting piece 6 is 2MM, and the outer surface of the adjusting piece 6 is a smooth surface. By selecting adjusting pieces 6 with the same thickness, a person can conveniently adjust the position of the fine-tuning plate 5.

[0029] Principle of use and advantages: During the use of the utility model, the mounting cylinder 2 is mounted on the external AGV vehicle frame through the mounting bolts 1, and both the mounting bolts 1 and the mounting cylinder 2 are coaxial with the electric push rod output shaft of the external electronic parking brake structure of the AGV vehicle. Moreover, the end of the brake cable inside the external electronic parking brake structure is clamped in the clamping groove at the end of the fine-tuning plate 5. Thus, when it is necessary to install the fine-tuning plate 5, first fix the mounting cylinder 2 through the mounting bolts 1. Then, the operator loosens the locking nut 3. At this time, there is a gap between the adjusting pieces 6. Then, the operator selects the position of the fine-tuning plate 5 according to the length of the brake cable and the wear condition of the brake pads. That is, first move the adjusting pieces 6 on both sides, and then place the end of the fine-tuning plate 5 away from the brake cable in this area through the main groove 4. At this time, the locking nut 3 can be tightened. When the locking nut 3 is tightened, it can squeeze the adjusting pieces 6 through the washer 8, so that the adjusting pieces 6 are closely attached to each other. Thus, the clamping and fixing effect on the end of the fine-tuning plate 5 can be indirectly achieved, that is, at this time, the fine-tuning plate 5 and the mounting cylinder 2 are in a fixed connection state.

[0030] Therefore, in the above process, when the position of the fine-tuning plate 5 needs to be adjusted due to the wear of the brake pads or other reasons, the locking nut 3 can be loosened, so that there is a gap between the adjusting pieces 6. Then, the operator can easily remove the fine-tuning plate 5 and easily move the adjusting pieces 6. That is, by moving the adjusting pieces 6, the effect of adjusting the distance between the fine-tuning plate 5 and the locking nut 3 is achieved, so as to realize the effect of adjusting the position of the fine-tuning plate 5. The tightness of the brake cable can be adjusted according to the wear condition of the external brake pads, thus avoiding over-loose or over-tight brakes. Since both the fine-tuning plate 5 and the adjusting pieces 6 are symmetrically arranged on both sides of the mounting cylinder 2, the operator can adjust different distances for the two fine-tuning plates 5 according to the specific use situation, that is, further improving the adaptability of the present solution during use.

[0031] It should be further noted that the setting of the secondary groove 7 enables two pairs of grooves to be symmetrically arranged up and down in the adjustment area. Further, with the combined cooperation of the main groove 4 and the secondary groove 7, the adjustment piece 6 can only move within the adjustment area and cannot break away from the adjustment area by itself. Thus, when a person adjusts the position of the fine-tuning plate 5, it is more convenient. The setting of the washer 8 enables the locking nut 3 not to directly contact the adjustment piece 6 when rotating, thereby avoiding the phenomenon that the adjustment piece 6 is damaged when the locking nut 3 rotates. The setting of the scale pattern and the indicating arrow 9 enables a person to conveniently judge whether the locking nut 3 is tightened when tightening the locking nut 3, and whether the locking nut 3 is loose during long-term use. The setting of the clamping protrusion enables the washer 8 not to rotate randomly during use, thereby making it easier to cooperate between the scale pattern and the indicating arrow 9. The setting of the magnetic stripe 10 enables the mounting cylinder 2 to have a certain degree of magnetic attraction effect on the fine-tuning plate 5, that is, the fine-tuning plate 5 is not easily separated from the mounting cylinder 2 during installation and position adjustment, thereby improving the convenience of operation for a person; the setting of the anti-slip pattern 11 makes it more firm and not easily loose when the mounting bolt 1 fixes the mounting cylinder 2; the outer surface of the adjustment piece 6 is a smooth surface, and by selecting the adjustment piece 6 with the same thickness, a person can conveniently adjust the position of the fine-tuning plate 5.

[0032] The above is only a preferred specific embodiment 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, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
