Background

Electronic parking refers to a technique for realizing parking braking by an electronic control method. Specifically, parking is achieved by driving the parking bolt 900 shown in fig. 1 to rotate around the axial direction so that a clamping block 921 formed by the parking bolt 900 is clamped with a bayonet formed by a nut in a brake mechanism on a vehicle; and the parking bolt 900 is rotated around the axial direction to separate the fixture block 921 formed by the parking bolt 900 from the bayonet formed by the nut for actuation.

The fixture block 921 forms an abutment wall 9211 that is in engagement with the bayonet, and the abutment wall 9211 extends along the axial direction of the parking bolt 900 to form a central plane 90001, and if the vertical distance between the thread starting point 9111 on the parking bolt and the central plane 90001 is large, the parking bolt 900 may be engaged with the nut too early or too late in the braking process, so that the time required for braking is too short or too long. Therefore, the parking bolt needs to detect the degree of positional deviation between the thread start point 9111 and the abutment wall 9211 formed by the parking bolt 900 before shipment to ensure that the parking bolt 900 can be used normally afterwards.

Because parking bolt has multiple model, parking bolt screw pitch, the diameter of different models are all different, and current detection device can only detect the parking bolt of single model, leads to parking bolt's detection cost big.

Referring to fig. 2 to 8, a detection apparatus for different sizes of parking bolts for automobiles according to a preferred embodiment of the present utility model will be described in detail below, in which a parking bolt 900 includes a shank 910 and a head 920. An end of the rod 910 extends radially to form the head 920. The outer circumference of the rod 910 forms a screw structure 911 so that the parking bolt 900 is screw-mounted to a nut in a vehicle brake mechanism, and the screw structure 911 forms a start end portion 9111 at an end portion remote from the head portion 920. The head 920 forms a block 921 toward the rod 910. The clamping block 921 can be clamped with a bayonet formed by a nut to brake. A side wall of the fixture block 921 screwed into the nut to be abutted against the inner wall of the bayonet is defined as an abutment wall 9211. The detection device for different sizes of parking bolts is used for detecting the vertical distance between a central surface 90001 formed by the abutting wall 9211 extending along the axial direction of the rod 910 and the starting end portion 9111.

Referring to fig. 2 to 8, in particular, the detection device for different sizes of parking bolts of automobiles includes an apparatus body 10, a belt moving member 20, and a measuring mechanism 30.

Referring to fig. 5 and 6, the apparatus body 10 includes a fixing member 11. The fixing member 11 forms a threaded hole 1101 and a side 1102 which are adapted to the threaded structure 911 of the rod 910. The threaded hole 1101 allows the shank 910 of the parking bolt 900 to be screwed in or out, and the fixture block 921 remains opposite to the side 1102 when the shank 910 is screwed into the threaded hole 1101.

Referring to fig. 7, the belt shifter 20 partially protrudes from the side 1102 formed by the fixing member 11, and the belt shifter 20 forms an inclined pressed wall 21 at an end protruding from the side 1102. The pressed wall 21 is disposed on a moving locus of the clamp block 921 that rotates around the axis of the parking bolt 900 to be close to the side 1102, wherein the pressed wall 21 is obliquely oriented to rotate around the axis of the parking bolt 900 to be close to the clamp block 921 of the side 1102 to provide a place for the clamp block 921 to press the belt moving member 20. The belt shifter 20 can be pressed and moved by the block 921 formed by the parking bolt 900 screwed into the screw hole 1101.

The measuring mechanism 30 is mounted to the apparatus body 10 to measure a distance by which the belt moving member 20 is pressed by the fixture block 921 screwed to a predetermined position to move in an axial direction parallel to the screw hole 1101.

Referring to fig. 3 and 4, it can be understood that, during the screwing of the rod 910 of the parking bolt 900 into the threaded hole 1101 formed in the fixing member 11, the clamp block 921 presses the belt shifter 20 to protrude from an end of the side surface 1102 formed in the fixing member 11 to move the belt shifter 20 toward a side away from the head 920, and after the parking bolt 900 is screwed to the preset position and held in abutment with the belt shifter 20, the belt shifter 20 stops moving, and the measuring mechanism 30 measures data. Since the starting end portions 9111 formed by the parking screws 900 of the same type are different from the respective central surfaces 90001 in terms of deviation, the position where the clamp block 921 of each parking screw 900 first contacts the pressed wall 21 is different, so that the degree of movement of the belt moving member 20 pushed by the clamp block 921 rotating to the preset position is different, and the values measured by the measuring mechanism 30 are different. The data measured by the measuring means 30 is compared with a preset range to determine whether the detected parking bolt 900 is acceptable.

Referring to fig. 5 to 8, the fixing member 11 preferably forms a sliding passage 1103 axially parallel to the threaded hole 1101, and the belt moving member 20 is slidably partially inserted into the sliding passage 1103.

Referring to fig. 7, further, an end of the belt moving member 20 extending out of the side surface 1102 further forms an abutted wall 22, and the abutted wall 22 is perpendicular to the axial direction of the sliding channel 1103. The pressed wall 21 is adjacent to the abutted wall 22, and the fixture block 921 moves along the pressed wall 21 to be abutted against the abutted wall 22 during screwing of the rod body 910 into the threaded hole 1101 formed by the fixing member 11, and the abutted wall 22 increases the abutment area of the belt moving member 20 and the fixture block 921, so that the belt moving member 20 is stably pressed to reduce the shake of the belt moving member 20, so that the measuring mechanism 30 measures accurate data.

Further, the detecting device for different sizes of automobile parking bolts further includes a stopper 40.

Specifically, the stopper 40 is mounted to the fixing member 11, and a part of the stopper 40 protrudes from the side surface 1102. The portion of the stopper 40 protruding from the side surface 1102 forms a stopper wall 41 that can abut against the abutment wall 9211, and the stopper wall 41 is disposed on a movement locus of the latch block 921 that rotates around the axis of the parking bolt 900 to be close to the side surface 1102.

The clamp block 921 pushes the belt moving member 20 to move by pressing the pressed wall 21, and then the clamp block 921 rotates along the pressed wall 21 to be abutted against the abutted wall 22, so that the clamp block 921 continues to rotate by a preset angle while remaining abutted against the abutted wall 22, so that finally the abutment wall 9211 abuts against the stopper wall 41, thereby limiting the rotation of the parking bolt 900 to the preset position.

Preferably, the stop member 40 extends a shorter length from the side surface 1102 than from the side surface 1102 when the belt shifter 20 is not pressed by the clamp block 921, to ensure that the clamp block 921 rotates about the axis of the parking bolt 900 to preferentially contact the belt shifter 20 when moving closer to the side surface 1102.

Referring to fig. 5 and 6, the fixing member 11 preferably includes a fixing portion 111, a detachable portion 112, and at least one connection structure 113. The fixing portion 111 forms the slide passage 1103 and the side 1102. The fixed portion 111 further forms a movable passage 11101, the detachable portion 112 forms the screw hole 1101, and the detachable portion 112 is detachably inserted into the movable passage 11101. The connection structure 113 is provided to the fixing member 11 so as to be capable of fixing or removing the detachable portion 112 and the fixing portion 111.

That is, different ones of the removable portions 112 may form different sizes of the threaded holes 1101. The detection device for different sizes of parking bolts of automobiles detects different models of parking bolts 900 by replacing the detachable portion 112 forming the threaded hole 1101 of different sizes.

Preferably, the connection structure 113 includes a connection threaded pin 1131 and a connection threaded channel 1132, wherein the fixed portion 111 forms the connection threaded channel 1132 in communication with the movable channel 11101. The coupling screw pin 1131 is detachably mounted to the coupling screw channel 1132 formed in the fixing part 111 and moves into and out of the movable channel 11101 through the coupling screw channel 1132. When the connection threaded pin 1131 is screwed into the connection threaded channel 1132 and extends into the movable channel 11101, the connection threaded pin 1131 abuts against the outer wall of the detachable portion 112 in the movable through groove 11101, so as to fix the detachable portion 112.

Preferably, the detachable portion 112 forms a pressure receiving wall 1121, and the pressure receiving wall 1121 can abut against the connecting threaded pin 1131 extending into the movable channel 11101. The pressure receiving wall 1121 increases the abutment area with the connection screw pin 1131, so that the connection screw pin 1131 firmly connects the detachable portion 112 and the fixing portion 111.

Further, the apparatus body 10 further includes a support table 12. The fixing portion 111 is attached to the support base 12.

Referring to fig. 3 and 4, the measuring mechanism 30 preferably includes a measuring member 31 and a measuring rod 32. The measuring member 31 is mounted to the support table 12. The measuring bar 32 is provided at an end of the belt moving member 20 remote from the pressed wall 21 so as to be movable in an axial direction parallel to the slide passage 1103 by being driven by the belt moving member 20 pressed by the clamp block 921. The measuring member 31 is connected to the measuring rod 32, and is configured to rotate the parking bolt 900 to the preset position to drive the moving distance of the belt moving member 20 to be represented by a dial.

In one example, the measuring mechanism 30 may be implemented as a dial indicator or dial gauge, or the like.

Referring to fig. 4 and 8, further, the support table 12 includes a table body 121, a support 122, and a fastening structure 123. The support 122 and the fixing portion 111 are both mounted to the table body 121. The support 122 defines an insertion passage 12201. The measuring member 31 is partially inserted in the insertion passage 12201.

Preferably, the support 122 forms an opening 12202 communicating with the insertion passage 12201 at an end portion remote from the table body 121. The opening 12202 divides one end portion of the support 122 into two attachment portions 1221, thereby adjusting the radial direction of the insertion passage 12201. The fastening structure 123 is detachably connected to the attaching portion 1221 in such a manner as to be able to narrow or enlarge the insertion passage 12201 in the radial direction.

Specifically, the fastening structure 123 includes a mounting threaded passage 1231 and a mounting threaded pin 1232. The mounting threaded pin 1232 is threadably mounted to the mounting threaded channel 1231. The support 122 forms the mounting screw passage 1231 at the two coupling parts 1221, and the axial direction of the mounting screw passage 1231 is perpendicular to and does not intersect the axial direction of the insertion passage 12201. The measuring member 31 may be fixedly inserted into the insertion passage 12201 while the mounting screw pin 1232 is screw-coupled to the mounting screw passage 1231 to narrow the insertion passage 12201 in a radial direction; the measuring member 31 may be inserted into or removed from the insertion passage 12201 when the mounting threaded pin 1232 is removed from the mounting threaded passage 1231 to enlarge the insertion passage 12201 in a radial direction. In this way, the operator can replace the measuring mechanism 30, such as a dial indicator or dial indicator, according to the actual use.

Referring to fig. 2, further, the detecting device for different sizes of parking bolts of automobiles further includes a reset member 50.

The reset member 50 is disposed between the support member 122 and the belt shifter 20, and when the belt shifter 20 is pressed by the clamp block 921 to move, the reset member 50 is elastically deformed and has a tendency to drive the belt shifter 20 to reset, so that the belt shifter 20 can be quickly reset after the parking bolt 900 is unscrewed for subsequent detection.

In one example, the return element 50 is embodied as a spring.
