[0031] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0032] Reference below Figure 1-Figure 3 The mounting device 100 of the crankshaft encoder 200 according to the embodiment of the present invention is described. The mounting device 100 can be mounted on the crankshaft pulley 300 .

[0033] The mounting device 100 of the crankshaft encoder 200 according to the embodiment of the present invention is as follows: Figure 1-Figure 3As shown, the mounting device 100 may include: a connecting member 10 and a plunger 20, the connecting member 10 is formed with a first assembly hole 11 extending along a first direction, the first assembly hole 11 is used to install the encoder shaft 210 of the crankshaft encoder 200, and the connecting member 10 is also formed with a second assembly hole 12 extending along a second direction, the second assembly hole 12 is connected to the first assembly hole 11, the first direction and the second direction are perpendicular, at least a portion of the plunger 20 is assembled in the second assembly hole 12, and the plunger 20 can reciprocate relative to the connecting member 10 along the second direction to move the plunger 20 to a locked position or an unlocked position.

[0034] It should be noted that since the vehicle cannot be moved, the status of the crankshaft encoder after installation cannot be observed during installation. The existing crankshaft encoder installation device cannot confirm whether the crankshaft encoder is correctly installed without observation. If the crankshaft encoder is not correctly installed, the crankshaft encoder is easily thrown out during testing, causing damage to the crankshaft encoder.

[0035] Based on this, the embodiment of the present application proposes a mounting device 100 for a crankshaft encoder 200. The mounting device 100 can be mounted on a crankshaft pulley 300. The crankshaft pulley 300 can be formed with a mounting groove, and the mounting groove can extend along the axial direction of the crankshaft pulley 300. The connecting member 10 can be assembled with the mounting groove, and the mounting device 100 can be fixedly connected to the crankshaft pulley 300 through the connecting member 10, and the crankshaft pulley 300 can drive the mounting device 100 to rotate together. The crankshaft encoder 200 can be mounted on the mounting device 100. When the crankshaft pulley 300 rotates, the crankshaft pulley 300 can drive the mounting device 100 to rotate together, and the mounting device 100 can drive the crankshaft encoder 200 to rotate together, thereby completing the crankshaft encoder 200 to measure the rotation speed of the crankshaft. As an example, the encoder shaft 210 of the crankshaft encoder 200 can be constructed as a columnar structure, and the outer peripheral surface of the encoder shaft 210 may include a first arc surface 220 and a first end surface 230, the first arc surface 220 and the first end surface 230 are adjacent to and connected, the first arc surface 220 and the first end surface 230 are constructed as the outer peripheral surface of the encoder shaft 210, the first arc surface 220 can extend along the circumference of the encoder shaft 210, the first end surface 230 can be constructed as a plane extending along the axial direction of the encoder shaft 210, and the first end surface 230 is spaced apart from the central axis of the encoder shaft 210.

[0036] The connecting member 10 may be formed with a first assembly hole 11 extending along a first direction. Figure 1 When setting the direction, the first direction is Figure 1The first assembly hole 11 can be used to install the encoder shaft 210 of the crankshaft encoder 200. The encoder shaft 210 can extend into the first assembly hole 11, and the first arc surface 220 of the encoder shaft 210 can abut against the inner wall of the first assembly hole 11. The connecting member 10 is also formed with a second assembly hole 12 extending along the second direction. Figure 2 When setting the direction, the second direction can be Figure 2 The first direction is perpendicular to the second direction. The first assembly hole 11 and the second assembly hole 12 are connected, and the second assembly hole 12 is located on one side of the first assembly hole 11 along the second direction. At least part of the plunger 20 can extend into the second assembly hole 12, and the plunger 20 can be constructed as a columnar structure with a circular cross-section. The plunger 20 can reciprocate relative to the connecting member 10 along the second direction, and the plunger 20 can move to a locked position or an unlocked position. When the crankshaft encoder 200 is installed correctly, the plunger 20 can move to the locked position, the plunger 20 is opposite to and abuts against the first end face 230, and the plunger 20 locks the crankshaft encoder 200, reducing the probability of the crankshaft encoder 200 falling off from the mounting device 100. When the plunger 20 moves to the unlocked position, the plunger 20 is separated from the encoder shaft 210, the encoder shaft 210 can be separated from the connecting member 10, and the crankshaft encoder 200 can be removed from the mounting device 100.

[0037] As an example, the connector 10 may include a first plate 15, a second plate 16, and a third plate 17. The first plate 15, the second plate 16, and the third plate 17 may be arranged in sequence along the first direction. The second plate 16 is connected between the first plate 15 and the third plate 17. The first plate 15, the second plate 16, and the third plate 17 may be integrally formed. The first plate 15 may be configured as a plate structure having a circular cross section. The first plate 15 may be assembled with the mounting groove. The first plate 15 may be fixedly connected to the crankshaft pulley 300 by means of snap connection, bonding, etc. The cross-sectional area of ​​the second plate 16 may be greater than the cross-sectional area of ​​the first plate 15. The second plate 16 may be connected to the crankshaft pulley 300 by means of bonding, bolt connection, etc. The second plate 16 is conducive to improving the connection strength between the connector 10 and the crankshaft pulley 300, and is conducive to improving the stability and safety of the installation of the crankshaft encoder 200. The first assembly hole 11 can penetrate the third plate body 17 and the second plate body 16 along the first direction and extend into the first plate body 15, which is beneficial to increase the installation space of the encoder shaft 210. The third plate body 17 can be formed with a second assembly hole 12 extending along the second direction, and the plunger 20 can reciprocate relative to the third plate body 17 along the second direction, and the plunger 20 can move to a locked position or an unlocked position.

[0038] When the encoder shaft 210 is assembled in the first assembly hole 11, if the plunger 20 can abut against the first end face 230 of the encoder shaft 210, the plunger 20 can move to the locking position, the encoder shaft 210 cannot rotate, the plunger 20 locks the crankshaft encoder 200, and the crankshaft encoder 200 is installed to the correct position. If the crankshaft encoder 200 is not installed in the correct position, the encoder shaft 210 can rotate relative to the connector 10, the plunger 20 cannot abut against the first end face 230, and the plunger 20 is in the unlocked position. When the plunger 20 abuts against the first arc surface 220 of the encoder shaft 210, the encoder shaft 210 can rotate, and the plunger 20 cannot lock the crankshaft encoder 200. The encoder shaft 210 continues to rotate to adjust the installation angle of the crankshaft encoder 200 until the encoder shaft 210 rotates to the first end face 230 abuts against the plunger 20, and the plunger 20 can move to the locking position, and the plunger 20 locks the crankshaft encoder 200, and the crankshaft encoder 200 is installed in the correct position. By determining whether the encoder shaft 210 can rotate, it can be confirmed whether the crankshaft encoder 200 is installed in the correct position.

[0039] As an example, a special installation tool 400 can be used when installing the crankshaft encoder 200. The installation tool 400 can be assembled with the encoder shaft 210, and the installation tool 400 can be engaged with the encoder shaft 210. When the installation tool 400 is rotated, the encoder shaft 210 can be driven to rotate together. The installation tool 400 may include a handle and a connecting portion. The connecting portion can be adapted to the shape of the encoder shaft 210, and the connecting portion can be engaged with the encoder shaft 210, so that the connecting portion can drive the encoder shaft 210 to rotate together, which is convenient for the staff to operate and is conducive to improving the installation efficiency. After the staff has assembled the installation tool 400 with the encoder shaft 210, the staff rotates the installation tool 400. If the installation tool 400 can be rotated, the encoder shaft 210 is rotated by rotating the installation tool 400, and the installation angle of the encoder shaft 210 is adjusted, so that the crankshaft encoder 200 is rotated to the correct position. If the installation tool 400 cannot be rotated, the crankshaft encoder 200 has been installed to the correct position.

[0040] In the embodiment of the present application, when the plunger 20 moves to the locking position, the plunger 20 locks the encoder shaft 210, the encoder shaft 210 cannot rotate, and the crankshaft encoder 200 is installed in the correct position. When the encoder shaft 210 can rotate, the plunger 20 cannot move to the locking position, and the installation angle of the crankshaft encoder 200 can be adjusted by rotating the encoder shaft 210. When the encoder shaft 210 cannot continue to rotate, the crankshaft encoder 200 is installed in the correct position. By setting the connector 10 and the plunger 20, by judging whether the encoder shaft 210 can rotate, it can be confirmed whether the crankshaft encoder 200 is installed in the correct position when the crankshaft encoder 200 cannot be observed, which is conducive to improving the convenience of the installation of the crankshaft encoder 200 and improving the safety of the use of the crankshaft encoder 200.

[0041] In some embodiments of the present invention, the mounting device 100 of the crankshaft encoder 200 may further include: a locking mechanism 30, which is disposed on the connecting member 10, and the locking mechanism 30 is selectively assembled with the plunger 20 to lock the plunger 20 in an unlocked position.

[0042] The locking mechanism 30 can be connected to the connecting member 10 by means of snap connection, bolt connection, etc. The locking mechanism 30 can be selectively assembled with the plunger 20. According to different working conditions, the locking mechanism 30 can lock the plunger 20 in an unlocked position, or the locking mechanism 30 can be separated from the plunger 20 so that the plunger 20 can move freely.

[0043] When the crankshaft encoder 200 does not need to be installed, the locking mechanism 30 can be assembled with the plunger 20, so that the plunger 20 is locked in the unlocked position, which can reduce the probability of the plunger 20 coming out of the second assembly hole 12 and avoid the plunger 20 from being lost. When the crankshaft encoder 200 needs to be installed on the installation device 100, the locking mechanism 30 can lock the plunger 20 in the unlocked position, and the plunger 20 can avoid the encoder shaft 210, so that the encoder shaft 210 can be smoothly inserted into the first assembly hole 11. When the encoder shaft 210 of the crankshaft encoder 200 is installed in the first assembly hole 11, the locking mechanism 30 is separated from the plunger 20, and the plunger 20 moves along the second direction. The plunger 20 can abut against the encoder shaft 210. When the plunger 20 abuts against the first end face 230 of the encoder shaft 210, the plunger 20 moves to the locking position, and the plunger 20 locks the crankshaft encoder 200. When the plunger 20 abuts against the first arc surface 220 of the encoder shaft 210, the encoder shaft 210 can rotate, and the plunger 20 cannot lock the crankshaft encoder 200. The encoder shaft 210 continues to rotate to adjust the installation angle of the crankshaft encoder 200 until the encoder shaft 210 cannot rotate, the plunger 20 abuts against the first end surface 230, and the plunger 20 locks the crankshaft encoder 200. When the crankshaft encoder 200 needs to be removed from the mounting device 100, the plunger 20 can be moved along the second direction, and the locking mechanism 30 locks the plunger 20 in the unlocking position, and the plunger 20 can avoid the encoder shaft 210, so that the encoder shaft 210 can be smoothly pulled out of the first assembly hole 11.

[0044] As an example, the locking mechanism 30 can be configured as a push cylinder, which can include a push shaft. The locking mechanism 30 can be set in the unlocked position. When the installation device 100 needs to lock the plunger 20 in the unlocked position, the push cylinder can control the push shaft to extend, and the push shaft can abut against the plunger 20 to limit the plunger 20 from moving in the second direction, so that the plunger 20 is locked in the unlocked position. When the installation device 100 does not need to lock the plunger 20, the push shaft retracts and separates from the plunger 20, and the plunger 20 can move freely in the second direction. As another example, the locking mechanism 30 can be configured as an electric clamping mechanism, which can be set in the unlocked position. When the installation device 100 needs to lock the plunger 20 in the unlocked position, the electric clamping mechanism can clamp the plunger 20, so that the plunger 20 is locked in the unlocked position. When the installation device 100 does not need to lock the plunger 20, the electric clamping mechanism can release the plunger 20 and separate from the plunger 20, and the plunger 20 can move freely in the second direction.

[0045] In some embodiments of the present invention, Figure 2As shown, the locking mechanism 30 may include: a locking pin 31, a connecting member 10 having a third assembly hole 13 connected to the second assembly hole 12, the locking pin 31 is suitable for passing through the third assembly hole 13 and extending into the second assembly hole 12, and the plunger 20 has a limiting frame 21, and the limiting frame 21 has a locking hole that cooperates with the locking pin 31.

[0046] Along the second direction, the third assembly hole 13 and the second assembly hole 12 can be located on the same side of the first assembly hole 11, the third assembly hole 13 can be connected to the second assembly hole 12, the third assembly hole 13 can pass through a part of the structure of the connector 10, and the locking pin 31 can be inserted into the third assembly hole 13. As an example, the third assembly hole 13 can be located above the second assembly hole 12, which is conducive to preventing the locking pin 31 from coming out of the third assembly hole 13 under the action of gravity. The locking pin 31 can be inserted into the third assembly hole 13 and extend into the second assembly hole 12. The locking pin 31 can be used to lock the plunger 20. The plunger 20 has a limiting frame 21, the limiting frame 21 can be integrally formed with the plunger 20, the limiting frame 21 can be connected to the plunger 20 by snapping, and the limiting frame 21 and the plunger 20 move synchronously. The limiting frame 21 may be formed with a locking hole, the locking pin 31 may be inserted into the locking hole, the locking pin 31 may abut against the inner wall of the locking hole, and the locking pin 31 may be assembled with the limiting frame 21, so that the locking pin 31 can lock the limiting frame 21 and the plunger 20 in the unlocked position. When the installation device 100 needs to lock the plunger 20 in the unlocked position, the locking pin 31 may be inserted into the third assembly hole 13 and extend into the second assembly hole 12, the locking pin 31 is inserted into the locking hole, the locking pin 31 may abut against the locking hole for limiting, and the locking pin 31 is fixed to the frame 21, thereby preventing the plunger 20 from moving in the second direction, thereby achieving the effect of locking the plunger 20 in the unlocked position. When unlocking, the locking pin 31 is pulled out from the locking hole and the third assembly hole 13, the locking pin is separated from the limiting frame 21, the plunger 20 and the connecting member 10, and the plunger 20 can move freely in the second direction.

The limit frame 21 can be sleeved on the peripheral wall of the plunger 20, and the limit frame 21 can extend along the circumference of the plunger 20. Along the second direction, the end of the plunger 20 can be closer to the first assembly hole 11 than the end of the limit frame 21, so that the plunger 20 can abut against the encoder shaft 210. As an example, the limit frame 21 can include a frame body 211 and a limit portion 212, the frame body 211 and the limit portion 212 can be integrally formed, and an angle can be formed between the frame body 211 and the limit portion 212, which can be a right angle or similar to a right angle. The frame body 211 can be sleeved on the plunger 20, the frame body 211 can be interference fit with the plunger 20, the limit portion 212 can extend along the second direction, and the locking hole can penetrate the limit portion 212 along the radial direction of the limit frame 21.

[0049] There may be multiple locking holes, and the multiple locking holes may be arranged along the circumference of the plunger 20. The multiple locking holes may be evenly distributed on the limit portion 212 with the central axis of the plunger 20 as the symmetric center. The embodiment of the present application is described by taking the limit frame 21 including two locking holes as an example. The two locking holes may be arranged correspondingly along the radial direction of the plunger 20. The plunger 20 may be formed with a first avoidance hole, and the first avoidance hole may penetrate the plunger 20 along the radial direction of the plunger 20. The two locking holes may be arranged correspondingly to the first avoidance hole. The locking pin 31 may be sequentially penetrated in one of the locking holes, the first avoidance hole, and the other locking hole, so as to achieve the effect that the locking pin 31 is penetrated in the limit frame 21 and the plunger 20, so as to achieve the effect that the locking pin 31 can lock the plunger 20 and the limit frame 21 in the unlocked position.

[0050] In some embodiments of the present invention, the third assembly hole 13 extends along a third direction, and the first direction, the second direction and the third direction are perpendicular to each other.

[0051] The third assembly hole 13 can extend along the third direction. Figure 2 When setting the direction, the third direction is Figure 2 The first direction, the second direction and the third direction are perpendicular to each other. By setting the third assembly hole 13 vertically along the third direction, the locking pin 31 can be vertically extended into the second assembly hole 12, and the locking pin 31 can be vertically inserted into the locking hole, so that the assembly of the locking pin 31 is simple, which is conducive to improving the assembly efficiency of the locking pin 31.

[0052] In some embodiments of the present invention, a first operating portion 311 is fixedly disposed at the end of the locking pin 31 away from the connecting member 10.

[0060] The elastic member 50 can be constructed as a spring, a spring sheet, etc., and the elastic member 50 is arranged in the second assembly hole 12. The elastic member 50 can be located between the limit frame 21 and the fixed block 40, and the elastic member 50 can be connected to the limit frame 21 by bonding, clamping, etc., and the elastic member 50 can be connected to the fixed block 40 by bonding, clamping, etc. The elastic member 50 is compressed between the limit frame 21 and the fixed block 40. When the plunger 20 is locked in the unlocked position, the elastic member 50 is compressed, the elastic member 50 generates elastic force, and the elastic member 50 stores energy. When the encoder shaft 210 is assembled in the first assembly hole 11, the plunger 20 is unlocked, and the elastic member 50 releases energy. The elastic force of the elastic member 50 can push the plunger 20 to move toward the encoder shaft 210 along the second direction. When the plunger 20 abuts against the encoder shaft 210, the elastic member 50 is still compressed and the elastic member 50 still has elastic force. The elastic member 50 is always kept in a compressed state in the second assembly hole 12, and the elastic member 50 always has an elastic force that can push the plunger 20 to move. When the encoder shaft 210 rotates to adjust the installation angle of the crankshaft encoder 200, the plunger 20 can always abut against the encoder shaft 210 under the push of the elastic member 50, which is conducive to achieving the effect of automatic locking of the encoder shaft 210 by the plunger 20, making the installation operation of the crankshaft encoder 200 simple and convenient, and is conducive to improving the installation efficiency. In addition, by providing the elastic member 50, the plunger 20 can be prevented from falling off the connecting member 10 and the plunger 20 can be prevented from being lost, which is conducive to extending the service life of the plunger 20 and improving the safety of the installation device 100.

[0061] In some embodiments of the present invention, the elastic member 50 is sleeved on the plunger 20. By arranging the elastic member 50 to be sleeved on the plunger 20, the compactness of the structure of the elastic member 50 and the plunger 20 can be improved, and the space occupied by the elastic member 50 and the plunger 20 can be reduced.

[0062] In the embodiment of the present application, before measuring the speed and change of the cold start of the vehicle, the connecting member 10 is first installed on the crankshaft pulley 300, the limiting frame 21, the elastic member 50 and the fixing block 40 are fixedly connected, the limiting frame 21 and the elastic member 50 extend into the second assembly hole 12, and the fixing block 40 can be bonded to the connecting member 10. Then the plunger 20 is inserted into the fourth assembly hole 14 and extends into the second assembly hole 12, the limiting frame 21 is sleeved on the plunger 20, the plunger 20 and the limiting frame 21 are interference fit, and the plunger 20 and the limiting frame 21 are fixedly connected. The locking pin 31 is inserted into the third assembly hole 13, one of the locking holes, the first avoidance hole and the other locking hole, and the locking pin 31 locks the plunger 20 in the unlocked position. The mounting device 100 and the vehicle are frozen together in a low-temperature environment. When it is necessary to measure the rotation speed and change of the vehicle during cold start, the encoder shaft 210 of the crankshaft encoder 200 is inserted into the first assembly hole 11, and the locking pin 31 is removed from the connecting member 10. The plunger 20 moves toward the encoder shaft 210 under the push of the elastic member 50, and the plunger 20 can abut against the encoder shaft 210. If the encoder shaft 210 cannot rotate under the drive of the mounting tool 400, the crankshaft encoder 200 is installed in the correct position. If the encoder shaft 210 can rotate, continue to rotate the encoder shaft 210 until the encoder shaft 210 can no longer rotate. When a clicking sound is heard, the crankshaft encoder 200 is installed in the correct position.
