Technical Field

[0002] In modern equipment, various locks (such as door locks) are often used. Door locks usually have a handle (handle: for example, a door handle grasped by a user's hand). During the installation process of the door, the rotation position of the handle usually needs to be adjusted (for example, some doors need to open to the left (left opening: the door opens on the left side when facing the door), and some doors need to open to the right (right opening: the door opens on the right side when facing the door)). The existing handle reversal (reversal: changing the initial rotation position of the handle) adjustment usually requires removing the screws that lock the handle, making the handle reversal very troublesome. In addition, the handle can easily twist the wiring harness inside the door lock during the process of adjusting the rotation position. Summary of the Invention

Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0035] Please also refer to Figures 1 to 5 The handle reversing mechanism provided by the present invention will now be described. The handle reversing mechanism comprises: a base 1; a handle 2 pivotally connected to the base 1 about a predetermined axis; a rotating member 3 disposed on the handle 2 and capable of switching between a first rotational position and a second rotational position about the predetermined axis; and a reset mechanism 4 for returning the rotating member 3 to the first rotational position if it deviates from the first rotational position, or returning the rotating member 3 to the second rotational position if it deviates from the second rotational position. The rotating member 3 has a first wire passage 31, and the handle 2 has a second wire passage 21 connected to the first wire passage 31.

[0036] In this way, the handle 2 is pivotally connected to the base 1 around a predetermined axis, and the handle 2 can rotate relative to the base 1 around a predetermined axis; the rotating member 3 is provided on the handle 2, and when the handle 2 is rotated, the rotating member 3 can be driven to rotate around a predetermined axis; the wiring harness 5 can pass through the first wiring channel 31 on the rotating member 3 and the second wiring channel 21 on the handle 2 in sequence, so that in the process of rotating the handle 2, the wiring harness 5 can rotate together with the handle 2 and the rotating member 3, and it is not easy to damage the wiring harness 5; the rotating member 3 can switch between a first rotation position and a second rotation position; when the rotating member 3 is in the first rotation position, if the handle 2 drives the rotating member 3 to rotate and deviates from the first rotation position, and then the handle 2 removes the external force, the reset mechanism 4 can restore the rotating member 3 to the first rotation position, thereby ensuring the position of the rotating member 3. Stable, and also reduce the possibility of sprains of the wiring harness 5 passing through the first wire passing channel 31 and the second wire passing channel 21; when the rotating part 3 is in the second rotation position, if the handle 2 drives the rotating part 3 to rotate and deviate from the second rotation position, and then the handle 2 removes the external force, the reset mechanism 4 can restore the rotating part 3 to the second rotation position, thereby ensuring the stability of the position of the rotating part 3, and reducing the possibility of sprains of the wiring harness 5 passing through the first wire passing channel 31 and the second wire passing channel 21; when the user needs to adjust the initial position of the handle 2, it only needs to rotate the rotating part 3 from the first rotation position to the second rotation position, or rotate the rotating part 3 from the second rotation position to the first rotation position; in addition, the handle 3 can be switched between the first rotation position and the second rotation position to achieve the reversal of the handle 2, which is very convenient.

[0037] In one embodiment, the base 1 is a housing of a lock.

[0038] In one embodiment, the predetermined axis may be the axis of a shaft, and the shaft may be a part of the rotating member 3 or the handle 2; the rotating member 3 is pivotally connected to the base 1 through the shaft, or the handle 2 is pivotally connected to the base 1 through the shaft.

[0039] In one embodiment, when the initial position of the rotating member 3 is at the first rotation position and when the rotating member 3 deviates (external force acts on the handle 2, and the handle 2 drives the rotating member 3 to rotate) from the first rotation position by an angle less than 70°, after the external force is removed, the reset mechanism 4 can restore the rotating member 3 to the first rotation position.

[0040] In one embodiment, when the initial position of the rotating member 3 is at the second rotation position and the angle of the rotating member 3 deviating from the second rotation position (external force acts on the handle 2, and the handle 2 drives the rotating member 3 to rotate) is less than 70°, after the external force is removed, the reset mechanism 4 can restore the rotating member 3 to the second rotation position.

[0041] Further, see Figures 1 to 5As a specific embodiment of the handle reversing mechanism provided by the present invention, the reset mechanism 4 includes: a sliding member 41 slidably provided on the base body 1 and capable of approaching or moving away from the rotating member 3 along the radial direction of the predetermined axis (radial direction: the direction toward the predetermined axis and perpendicular to the predetermined axis) and a driving mechanism 42 for driving the sliding member 41 to move; the sliding member 41 has a limiting plane 411 parallel to the predetermined axis, and the rotating member 3 has a first planar surface 32 and a second planar surface 33 respectively parallel to the predetermined axis; when the rotating member 3 is in the first rotation position, the limiting plane 411 abuts against the first planar surface 32; when the rotating member 3 is in the second rotation position, the limiting plane 411 abuts against the second planar surface 33. In this way, the sliding member 41 is slidably arranged on the seat body 1 along the radial direction of the predetermined axis, and the sliding member 41 can approach or move away from the rotating member 3 during the sliding process, and the driving mechanism 42 drives the sliding member 41 to move toward the rotating member 3 to abut against the rotating member 3; since the sliding member 41 has a limiting plane 411, the rotating member 3 has a first plane surface 32 and a second plane surface 33, that is, the limiting plane 411, the first plane surface 32 and the second plane surface 33 are respectively parallel to the predetermined axis; when the rotating member 3 rotates to the first rotation position, the first plane surface 32 abuts on the limiting plane 411, and when the rotating member 3 deviates from the first rotation position under the action of an external force, the rotating member 3 will push the sliding member 41 away from the rotating member 3 during the rotation process (since the limiting plane 411 and the first plane surface 32 are respectively parallel to the predetermined axis, when the limiting plane 411 abuts on the first plane surface 32, the sliding member 41 is closest to the predetermined axis). When the external force on the rotating member 3 is removed, the sliding member 41 moves away from the rotating member 3. When the cam 41 is pushed by the driving mechanism 42 and approaches the rotating member 3, the rotating member 3 rotates toward the first rotation position until the first plane surface 32 abuts the limiting plane 411 and stops rotating. At this time, the rotating member 3 is reset to the first rotation position; when the rotating member 3 rotates to the second rotation position, the second plane surface 33 abuts on the limiting plane 411. When the rotating member 3 deviates from the second rotation position under the action of external force, the rotating member 3 will push the sliding member 41 away from the rotating member 3 during the rotation process (because the limiting plane 411 and the second plane surface 33 are respectively parallel to the predetermined axis, when the limiting plane 411 abuts on the second plane surface 33, the sliding member 41 is closest to the predetermined axis). After the external force of the rotating member 3 is removed, the sliding member 41 is pushed by the driving mechanism 42 and approaches the rotating member 3. When the rotating member 3 rotates toward the second rotation position until the second plane surface 33 abuts on the limiting plane 411 and stops rotating, at this time, the rotating member 3 is reset to the second rotation position.

[0042] In one embodiment, the sliding direction of the sliding member 41 is perpendicular to the limiting plane 411 .

[0043] In one embodiment, first planar surface 32 and second planar surface 33 are parallel.

[0044] In one embodiment, the base body 1 has a slot 414 , and the sliding member 41 has a guide bar 413 slidably disposed in the slot 414 .

[0045] In one embodiment, the sliding member 41 has a strip-shaped hole 415 extending radially toward the predetermined axis, and the base body 1 has an inner guide member 412 inserted into the strip-shaped hole 415. In one embodiment, there are multiple strip-shaped holes 415 and multiple guide members 412, and the multiple strip-shaped holes 415 correspond to the multiple guide members 412. In one embodiment, the guide member 412 is a screw that is removably fixed to the base body 1.

[0046] Further, see Figures 1 to 5 In one embodiment of the handle reversing mechanism provided by the present invention, when the rotating member 3 rotates from the first rotational position to the second rotational position in a predetermined rotational direction F, the rotating member 3 rotates through an angle between 90° and 180°. Thus, the handle 2 drives the rotating member 3 to switch between the first and second rotational positions, enabling the handle 2 to switch between angles between (greater than or equal to 90°) and (less than or equal to 180°).

[0047] In one embodiment, see Figure 4 When the rotating member 3 rotates from the first rotation position to the second rotation position in the predetermined rotation direction F, the rotation angle of the rotating member 3 is 180°.

[0048] Further, see Figures 1 to 5As a specific embodiment of the handle reversing mechanism provided by the present invention, the rotating member 3 has a protrusion 34, and the base body 1 has a limiting boss 11; the protrusion 34 has a first abutting end 341 and a second abutting end 342 arranged opposite to each other, and the limiting boss 11 has a first limiting end 111 and a second limiting end 112 arranged opposite to each other; in the predetermined rotation direction F, the first limiting end 111, the first abutting end 341, the second abutting end 342, and the second limiting end 112 are arranged in sequence; the first limiting end 111 is located on the moving path of the first abutting end 341, and the second limiting end 112 is located on the moving path of the second abutting end 342. In this way, the rotating member 3 can be rotated from the first rotation position toward the predetermined rotation direction F to the second rotation position; when the rotating member 3 rotates from the first rotation position toward the direction opposite to the predetermined rotation direction F, the first abutting end 341 on the protrusion 34 abuts against the first limiting end 111 and is limited by the first limiting end 111, preventing the rotating member 3 from rotating too much from the first rotation position toward the direction opposite to the predetermined rotation direction F and twisting the wiring harness 5; when the rotating member 3 rotates from the second rotation position toward the predetermined rotation direction F, the first abutting end 341 on the protrusion 34 abuts against the second limiting end 112 and is limited by the second limiting end 112, preventing the rotating member 3 from rotating too much from the second rotation position toward the predetermined rotation direction F and twisting the wiring harness 5.

[0049] In one embodiment, the first abutting end 341 and the second abutting end 342 are connected via a first reinforcing rib.

[0050] In one embodiment, the first limiting end 111 and the second limiting end 112 are connected via a second reinforcing rib.

[0051] Further, see Figures 1 to 5 As a specific embodiment of the handle reversing mechanism provided by the present invention, it is set that when the first limit end 111 abuts the first abutting end 341, the rotating member 3 is located at the third rotation position; it is set that when the second limit end 112 abuts the second abutting end 342, the rotating member 3 is located at the fourth rotation position; when the rotating member 3 rotates from the first rotation position to the third rotation position, the rotating member 3 rotates 30° to 60°; and / or when the rotating member 3 rotates from the second rotation position to the fourth rotation position, the rotating member 3 rotates 30° to 60°. In this way, when the rotating member 3 rotates from the first rotation position in a direction opposite to the predetermined rotation direction F, the rotation range of the rotating member 3 is limited to 30° to 60°; when the rotating member 3 rotates from the second rotation position in a direction opposite to the predetermined rotation direction F, the rotation range of the rotating member 3 is limited to 30° to 60°.

[0052] Further, see Figures 1 to 5As a specific embodiment of the handle reversing mechanism provided by the present invention, the first abutting end 341 has a first abutting plane, and the second abutting end 342 has a second abutting plane. The first limiting end 111 has a first limiting plane 411 for abutting the first abutting plane, and the second limiting end 112 has a second limiting plane 411 for abutting the second abutting plane. This ensures a more stable contact when the first abutting plane abuts the first limiting plane 411, and an even more stable contact when the second abutting plane abuts the second limiting plane 411.

[0053] Further, see Figures 6 to 13 As a specific embodiment of the handle reversing mechanism provided by the present invention, the first wire-passing channel 31 is a first through hole opened on the rotating member 3; the second wire-passing channel 21 includes: a second through hole 212 opened on the handle 2 and a concave cavity 22 formed on the handle 2 along the extension direction of the predetermined axis; the rotating member 3 has a pin body 35; a sliding groove for the pin body 35 to slide into in the extension direction of the predetermined axis is formed on one side wall of the concave cavity 22, and a wire-passing gap space 211 connected to the first through hole is formed between the pin body 35 and the other side wall of the concave cavity 22, and the wire-passing gap space 211 is connected to the second through hole 212. In this way, when installing the rotating part 3, the pin body 35 on the rotating part 3 can be inserted into the slide groove in the concave cavity 22 on the handle 2, which is conducive to maintaining relative stability between the rotating part 3 and the handle 2, and it is very convenient to assemble the rotating part 3 and the handle 2; the wiring harness 5 can pass through the first through hole, the wire gap space 211 and the second through hole 212 in sequence; the wire gap space 211 is formed between the pin body 35 and the side wall of the concave cavity 22, and the wire gap space 211 can be adjusted in the axial direction of the predetermined axis by sliding the pin body 35 into the slide groove at different positions; the wire gap space 211 can be adjusted in the radial direction of the predetermined axis by sliding the pin body 35 into the slide groove at different rotation angles.

[0054] In one embodiment, the base body 1 is provided with an assembly hole, the pin body 35 is inserted into the assembly hole, and a bearing is provided between the pin body 35 and the inner wall of the assembly hole, so that the pin body 35 can rotate relative to the base body 1.

[0055] In one embodiment, the first through hole is in the shape of an elongated strip in a direction perpendicular to the predetermined axis, so that the wiring harness 5 can be adjusted along the first elongated through hole, thereby reducing the possibility of the wiring harness 5 being twisted. In one embodiment, the wire gap space 211 extends in the direction of the predetermined axis, so that the wiring harness 5 can be arranged along the extension direction of the predetermined axis, thereby reducing the possibility of the wiring harness 5 in the wire gap space 211 being twisted when the handle 2 rotates around the predetermined axis. In one embodiment, in a projection plane perpendicular to the predetermined axis, the projections of the first through hole and the wire gap space 211 have an overlapping area, and the area of ​​the overlapping area is smaller than the area of ​​the first through hole. When the wiring harness 5 enters the wire gap space 211 through the first through hole, the adjacent portion of the wire gap space 211 and the first through hole is stepped, thereby reducing the possibility of the wiring harness 5 being twisted due to mutual misalignment at the adjacent portion of the wire gap space 211 and the first through hole. In one embodiment, in a projection plane perpendicular to a predetermined axis, the wire gap space 211 is enclosed by straight edges and arcs to form a small semicircle (smaller than the area of ​​the semicircle), so that the wire harness 5 can slide along the arc surface when shaking in the wire gap space 211, thereby reducing friction. In one embodiment, in a projection plane perpendicular to a predetermined axis, the straight edge extension direction of the wire gap space 211 is the same as the extension direction of the long strip-shaped first through hole, so that the wire harness 5 can also easily slide along the straight edge of the wire gap space 211 when sliding laterally along the first through hole, thereby facilitating the movement of the wire harness 5 and reducing the possibility of the wire harness 5 being twisted or scratched. In one embodiment, in a projection plane perpendicular to a predetermined axis, the arc is a circular arc, and the center of the arc is located on the predetermined axis, so that when the handle 2 drives the wire harness 5 to rotate during rotation, the wire harness 5 can adjust its position along the circular arc to adapt to the rotation of the handle 2, thereby reducing the possibility of the handle 2 twisting the wire harness 5. In one embodiment, within a projection plane perpendicular to the predetermined axis, the projection area of ​​the wire-passing gap space 211 is located within the first through-hole. In one embodiment, the wire-passing gap space 211 extends in the direction of the predetermined axis. In one embodiment, within a projection plane perpendicular to the predetermined axis, the straight edge of the wire-passing gap space 211 coincides with the edge of the first through-hole. This allows the wire harness 5 to pass more smoothly through the first through-hole into the wire-passing gap space 211. In one embodiment, within a projection plane perpendicular to the predetermined axis, the inner sidewalls of the two ends of the elongated first through-hole are respectively a first curved surface and a second curved surface. The first curved surface intersects with one end of the straight edge of the wire-passing gap space 211, and the second curved surface intersects with the other end of the straight edge of the wire-passing gap space 211. This facilitates the wire harness 5 in contact with the first curved surface to slide toward and contact the straight edge of the gap space 211, resulting in a smooth transition and reducing the risk of twisting the wire harness 5. It also facilitates the wire harness 5 in contact with the second curved surface to slide toward and contact the straight edge of the gap space 211, resulting in a smooth transition and reducing the risk of twisting the wire harness 5.

[0056] Further, see Figures 1 to 5As a specific embodiment of the handle reversing mechanism provided by the present invention, the pin body 35 is detachably fixed to the bottom wall of the cavity 22 by a fastener 36. In this way, the rotating member 3 is very conveniently installed in the cavity 22 via the pin body 35. It only needs to lock the pin body 35 to the bottom wall of the cavity 22 with the fastener 36.

[0057] In one embodiment, the fastener 36 is a screw, and the tightening direction of the fastener 36 is parallel to the extending direction of the predetermined axis.

[0058] In one embodiment, in the projection direction along the predetermined axis, the pin body 35 is a rectangle with chamfered corners to prevent the pin body 35 from rotating in the cavity 22 .

[0059] In one embodiment, an annular reinforcing rib is provided on the rotating member 3 outside the pin body 35. One end of the annular reinforcing rib abuts the edge of the first through-hole, while the other end abuts the edge of the first through-hole. This annular reinforcing rib can transfer stress from the rotating member 3 to the pin body 35 from multiple directions, and can also transfer stress from the edge of the first through-hole to the pin body 35, thereby reducing deformation of the first through-hole.

[0060] Further, see Figures 1 to 5 As a specific embodiment of the handle reversing mechanism provided by the present invention, the driving mechanism 42 is an elastic member, one end of the elastic member is connected to the sliding member 41, and the other end of the elastic member is connected to the base 1. In this way, the sliding member 41 is pushed by the elastic member, which is very convenient.

[0061] In one embodiment, the elastic member is a cylindrical spring. In one embodiment, one end of the cylindrical spring abuts against the seat body 1, and the other end of the cylindrical spring abuts against the sliding member 41. In one embodiment, the cylindrical spring extends in a radial direction of the predetermined axis.

[0062] In one embodiment, a protection cavity is formed between the sliding member 41 and the base body 1 , and the cylindrical spring is located in the protection cavity.
