Description

Technical Field

[0001] The present invention relates to the technical field of gear transmission, and in particular to a reciprocating mechanism, a locking mechanism and an electronic lock. Background Art

[0002] Current gear transmissions typically utilize a single row of teeth. Due to the inherent characteristics of gears, smaller gears have a smaller module, resulting in a smaller tooth thickness, and thus a lower bearing capacity. Increasing the bearing capacity of a gear requires a stronger material, which improves the processing and increases gear costs. Furthermore, due to material limitations, the inherent strength of the gear can only be increased to a limited extent. In other words, in relatively small gear transmissions, a smaller tooth thickness results in insufficient bearing capacity, while strengthening the gear material further increases material costs. Summary of the Invention

[0052] The reciprocating mechanism, locking mechanism and electronic lock according to the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0053] Reference Figure 1 and Figure 2 As shown, the reciprocating mechanism provided by the present invention includes a reciprocating member 10, an incomplete gear 20 and an elastic member 30. The reciprocating member 10 is provided with a first tooth portion 101; the incomplete gear 20 is provided with a second tooth portion 201, and the second tooth portion 201 is engaged with the first tooth portion 101, and is used to drive the reciprocating member 10 to move in a first direction; wherein, the first tooth portion 101 and the second tooth portion 201 are configured to be composed of multiple rows of tooth blocks, and the number of rows of tooth blocks has a preset proportional relationship; the elastic member 30 is connected to the reciprocating member 10 and is located in the movement direction of the reciprocating member 10, and is used to drive the reciprocating member 10 to move in the second direction when the second tooth portion 201 disengages from the first tooth portion 101.

[0054] Among them, the incomplete gear 20 indicates that its number of teeth is incomplete, and it can drive the reciprocating member 10 to form intermittent motion, and through the elastic cooperation of the elastic member 30, the reciprocating member 10 can form continuous reciprocating motion in the first direction and the second direction; optionally, the first direction can be set to the direction toward the elastic member 30, and the second direction can be set to the direction away from the elastic member 30. When the incomplete gear 20 drives the reciprocating member 10 to move in the first direction, the reciprocating member 10 can compress the elastic member 30. When the first tooth portion 101 disengages from the second tooth portion 201, the compressed elastic member 30 elastically opens, causing the reciprocating member 10 to move in the second direction. When the incomplete gear 20 continues to rotate, the first tooth portion 101 engages with the second tooth portion 201 again, so that the reciprocating member 10 forms a reciprocating motion, and the transmission efficiency is higher.

[0055] Specifically, the preset proportional relationship satisfies the following formula: x=p' / p, where x is the number of tooth block rows, p' is the tooth pitch of the thickened tooth block, and p is the tooth pitch of the non-thickened tooth block, and when n<x≤n+1, x is n+1, and n is a positive integer.

[0056] In this embodiment, the number of tooth block rows can be set to x. When the gear center distance a and the transmission ratio i are determined, the gear pitch circle diameter d is also determined. The gear pitch circle circumference = pitch circle diameter d×π = z×p (z is the number of teeth, p is the unthickened tooth pitch), p = s+e, (s is the tooth thickness, e is the tooth width, and s = e), where the pitch of the incomplete gear 20 with increased tooth thickness is set to p'. In order to make d = z×p = z×p', it is necessary to Divide the pitch p' of the increased tooth thickness by the number of tooth block rows x, and the following formula is obtained: d = z × p = z × p' / x, so x = p' / p, that is, the calculation between the pitch of the thickened tooth block and the pitch of the non-thickened tooth block is x, when n<x≤n+1, then x=n+1, that is, the number of tooth block rows is n+1, for example, x=1.25, then n=1, n+1=2, therefore, x is 2, and the number of tooth block rows is set to 2 rows.

[0057] The reciprocating mechanism provided by the present invention can set multiple rows of tooth blocks on the first tooth portion 101 on the reciprocating member 10 according to a preset proportional relationship, and set multiple rows of tooth blocks on the second tooth portion 201 on the incomplete gear 20 according to a preset proportional relationship. When the reciprocating member 10 moves, the incomplete gear 20 drives the reciprocating member 10 to move in the first direction and drives the reciprocating member 10 to move in the second direction through the elastic member 30. When designing the tooth blocks, the thickness of the tooth blocks can be increased, and the number of rows of tooth blocks can be increased according to the proportional relationship of the tooth block thickness. During continuous reciprocating motion, multiple rows of tooth blocks can make the gears have higher bearing capacity without changing the gear material, thereby reducing the overall cost.

[0058] Reference Figure 2As shown, a through hole 102 is provided on one side of the reciprocating member 10, and a guide column 40 is provided in the through hole 102. The end of the guide column 40 away from the through hole 102 extends outward and is provided with a contact portion 401; wherein, the elastic member 30 is sleeved on the guide column 40 and one end is connected to the contact portion 401, and the other end extends into the through hole 102 and is connected to the reciprocating member 10, so that the elastic member 30 drives the reciprocating member 10 to move in the second direction.

[0059] In this embodiment, the guide column 40 can fix the elastic member 30 in the through hole 102, and can fix the guide column 40. When the guide column 40 is fixed, the elastic force of the elastic member 30 acts on the abutment portion 401 and the reciprocating member 10. The fixed abutment portion 401 enables the elastic member 30 to push the reciprocating member 10 to move in the second direction, and the guide column 40 is in the through hole 102, which can make the reciprocating member 10 move only in the axial direction of the guide column 40, ensuring the stable and reliable operation of the reciprocating member 10.

[0060] Optionally, in some other embodiments, the reciprocating member 10 and the elastic member 30 can be housed and assembled together in the housing, and the guide column 40 can be extended from the through hole 102 and connected to the inner wall of the housing, so that the elastic member 30 can elastically push the reciprocating member 10 to move; further, when the elastic member 30 is set at a position close to the first direction, the elastic member 30 is set to push the reciprocating member 10 to move toward the second direction when stretched, and when the elastic member 30 is set at a position close to the second direction, the elastic member 30 can be set to pull the reciprocating member 10 to move toward the second direction when compressed.

[0061] Reference Figure 3 As shown, the reciprocating member 10 is provided with an accommodating cavity 103 , the first tooth portion 101 is disposed at the bottom or top of the accommodating cavity 103 , and the incomplete gear 20 is received in the accommodating cavity 103 to rotate in the accommodating cavity 103 .

[0062] In this embodiment, when the first tooth portion 101 is set at the top of the accommodating cavity 103, when the second tooth portion 201 of the incomplete gear 20 rotates to the top of the accommodating cavity 103, the second tooth portion 201 engages with the first tooth portion 101 and drives the reciprocating member 10 to move in the first direction; when the first tooth portion 101 is set at the bottom of the accommodating cavity 103, the incomplete gear 20 needs to be set to reverse so that the incomplete gear 20 can drive the reciprocating member 10 to move in the first direction; it can be understood that the rotation direction of the incomplete gear 20 needs to be set according to the different positions of the first tooth portion 101, so that the movement direction of the reciprocating member 10 driven by the incomplete gear 20 is the first direction.

[0063] Reference Figures 3 to 9As shown, at least two oppositely arranged limiting portions 202 are provided on the side of the incomplete gear 20 facing the accommodating cavity 103, and the at least two limiting portions 202 are formed as protrusions and are collectively configured as a limiting groove 203. A protruding limiting block 104 is formed on the side wall of the accommodating cavity 103 opposite to the limiting groove 203, wherein when the reciprocating member 10 moves toward the second direction, the limiting block 104 enters the limiting groove 203, and when the incomplete gear 20 stops rotating, at least two limiting portions 202 are in the moving direction of the limiting block 104, so as to force the at least two limiting portions 202 to abut against the limiting block 104, so as to limit the movement of the reciprocating member 10.

[0064] In this embodiment, states 1 to 4 are that the incomplete gear 20 drives the reciprocating member 10 to move toward the first direction. In state 4, after the incomplete gear 20 drives the reciprocating member 10 to move completely, at this time, at least two limiting portions 202 on the incomplete gear 20 are parallel to the moving direction of the upper limit block 104 of the reciprocating member 10, and at the same time, the second tooth portion 201 on the incomplete gear 20 is separated from the first tooth portion 101 on the reciprocating member 10, and the elastic member 30 pushes the reciprocating member 10 to move toward the second direction and enter the limiting groove 203. At this time, since only the two limiting portions 202 are in contact with the limiting block 104, the reciprocating member 10 moves in the second direction and enters the limiting groove 203. 104 is parallel to the moving direction of the limit block 104, so the horizontal movement of the limit block 104 does not interfere with the at least two limit parts 202. When the reciprocating member 10 is completely moved to the second direction and cannot move, it enters state 5, and the reciprocating member 10 stops completely. At this time, the incomplete gear 20 continues to rotate 1 / 4 circle and enters state 6. In this state, the limit block 104 is restricted in the horizontal direction by at least two limit parts 202, so that the reciprocating member 10 cannot move in the first direction and the second direction, thereby avoiding resonance and displacement when being struck, and being set in the lock has higher security.

[0065] Reference Figure 4 As shown, the first tooth portion 101 is configured to have a first tooth block group 1011 and a second tooth block group 1012 parallel to each other, the first tooth groove group formed by the first tooth block group 1011 faces the second tooth block group 1012, and the second tooth groove group formed by the second tooth block group 1012 faces the first tooth block group 1011.

[0066] Furthermore, the second tooth portion 201 is configured to have a third tooth block group 2011 and a fourth tooth block group 2012 parallel to each other, the third tooth groove group formed by the third tooth block group 2011 faces the fourth tooth block group 2012, and the fourth tooth groove group formed by the fourth tooth block group 2012 faces the third tooth block group 2011.

[0067] In this embodiment, the first tooth block group 1011 and the second tooth block group 1012 are staggered with each other, and the third tooth block group 2011 and the fourth tooth block group 2012 are staggered with each other. When the incomplete gear 20 drives the reciprocating member 10 to move, the first tooth block group 1011 and the third tooth block group 2011 are engaged, and the second tooth block group 1012 and the fourth tooth block group 2012 are engaged. When the reciprocating member 10 moves, the tooth blocks of the first tooth block group 1011 are engaged with the tooth blocks of the third tooth block group 2011, and then the tooth blocks of the second tooth block group 1012 are engaged with the tooth blocks of the fourth tooth block group 2012, thereby forming a continuous and uninterrupted movement, thereby ensuring the stability and continuity of the movement of the reciprocating member 10.

[0068] Among them, the tooth pitches of the first tooth block group 1011, the second tooth block group 1012, the third tooth block group 2011 and the fourth tooth block group 2012 can be set as thickened tooth blocks. Therefore, after the tooth blocks are thickened, the tooth pitches between the respective tooth blocks become larger, and the first tooth block group 1011 and the third tooth block group 2011 are meshed, and the second tooth block group 1012 and the fourth tooth block group 2012 are meshed. Since the first tooth block group 1011 and the second tooth block group 1012 are mutually offset, the third tooth block group 2011 and the fourth tooth block group 2012 are meshed. The four tooth block groups 2012 are mutually staggered, so that each tooth block can continuously engage and move, thereby ensuring its continuous movement; for example, the first tooth block group 1011 can be set to 1, 2, 3, and 4 tooth blocks, and the second tooth block group 1012 can be set to 5, 6, and 7 tooth blocks. The order of engagement during movement is 1, 5, 2, 6, 3, 7, and 4 respectively. It can be understood that when the number of tooth block rows is set to multiple rows, they can all be set in a staggered manner to ensure the continuity of the movement of the incomplete gear 20 and the reciprocating member 10.

[0069] Furthermore, a motor 50 is included, and the incomplete gear 20 is arranged on the motor shaft of the motor 50 so that the motor 50 drives the incomplete gear 20 to rotate.

[0070] In this embodiment, the incomplete gear 20 is driven to rotate by the motor 50, and the reciprocating member 10 is driven to move in the first direction, so that the motor 50 only needs to rotate in one direction, making it simpler to design the circuit of the motor 50, simplifying the circuit control method, and effectively reducing the circuit cost.

[0071] Reference Figure 5 and Figure 6As shown, in an embodiment of the present invention, a locking mechanism is further proposed, comprising a fixed shaft 60, a locking member 70, a stop rod 80, a torsion spring 90 and the reciprocating mechanism as described above, wherein the axial direction of the fixed shaft 60 is parallel to the movement direction of the reciprocating member 10; one end of the stop rod 80 is connected to the reciprocating member 10, and the other end extends close to the locking member 70; when the locking member 70 is in the locked position, the stop rod 80 is arranged to overlap with the rotation trajectory of the locking member 70 to limit the rotation of the locking member 70 to the unlocking position. Locked position; when the locking member 70 is in the unlocked position, the stop rod 80 is spaced apart from the rotation trajectory of the locking member 70 so that the locking member 70 can rotate freely; the locking member 70 can be pivoted on the fixed shaft 60 and can rotate around the fixed shaft 60 to the unlocked position and the locked position; the torsion spring 90 is sleeved on the fixed shaft 60 and at least one end is in contact with the rear end of the locking member 70. The torsion spring 90 is used to transmit the torsional force to the locking member 70 to force the locking member 70 to rotate naturally to the unlocked position.

[0072] When the locking member 70 is unlocked, the locking member 70 is held in the unlocked position by the torsional force of the torsion spring 90 in the natural state, and the reciprocating member 10 abuts against the side surface of the rear end of the locking member 70, so that the locking member 70 is in the open state in the natural state; wherein, the rotation trajectory of the locking member 70 represents the curved trajectory of the rotation of the locking member 70, and the stop rod 80 can be driven by the reciprocating member 10 so that the stop rod 80 moves to the curved trajectory of the rotation of the locking member 70, thereby blocking the locking member 70 from rotating to the unlocked position, so that the locking member 70 can be in the locked position, thereby improving its safety; optionally, the stop rod 80 can be integrally provided with the reciprocating member 10 or detachably provided, and those skilled in the art can set it arbitrarily according to actual needs, and no limitation is made here.

[0073] Furthermore, the front end of the locking member 70 has a pressing portion 701, which is used for the user to press to force the locking member 70 to push the torsion spring 90 and rotate to the locking position; wherein, when the locking member 70 rotates to the locking position, the elastic member 30 drives the reciprocating member 10 to move toward the locking member 70, and causes the reciprocating member 10 to abut against the rear end of the locking member 70 to limit the rotation of the locking member 70.

[0074] When the user presses the pressing portion 701 at the front end of the locking member 70 downward, the user overcomes the torsion force of the torsion spring 90 so that the locking member 70 is pivoted to the locking position around the fixed axis 60. At the same time, the reciprocating member 10 is driven by the elastic member 30 to disengage from the side of the locking member 70 and abut against the rear end of the locking member 70. The card slot at the rear end of the locking member 70 just cooperates with the reciprocating member 10, so that the locking member 70 cannot be rotated from the locked position to the unlocked position, so that the locking member 70 is in a locked state, which ensures the safety of the locked state of the locking member 70 and makes locking faster and more convenient.

[0075] Furthermore, when the locking member 70 is rotated from the locked position to the unlocked position, the motor 50 is controlled to drive the incomplete gear 20 to drive the reciprocating member 10 to move in a direction away from the locking member 70, so that the reciprocating member 10 is disengaged from the rear end of the locking member 70. At the same time, the torsion force of the torsion spring 90 can drive the locking member 70 to rotate from the locked position to the unlocked position, so that the locking member 70 is switched from the locked state to the unlocked state, which is more convenient, safe and reliable to use.

[0076] An embodiment of the present invention also provides an electronic lock including the aforementioned locking mechanism. The electronic lock can be a shopping cart lock.
