[0037] In order to facilitate the understanding of the embodiments of the present application, the embodiments of the present application will be described in more detail below with reference to the relevant drawings. The preferred embodiments of the present application are shown in the drawings. However, the present application can be realized in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0038] ​​​​​​​​​​Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description herein is for describing particular embodiments only and is not intended to be limiting of the application.

[0039] Please refer to Figures 1 to 5 The handle device 1 provided by the present application comprises a housing 10, a handle assembly 20, a clutch assembly 30 and an elastic member 40. The handle assembly 20 comprises a door handle 21 and a rotating assembly 23 connected with each other, the door handle 21 is arranged on one side of the housing 10, and the rotating assembly 23 is rotatably arranged on the housing 10 and is provided with a transmission hole 231. The clutch assembly 30 comprises a clutch rotating block 31 and a latch 33, the clutch rotating block 31 is rotatably arranged on the housing 10 and can be inserted with a lock core lever, the clutch rotating block 31 is in transmission cooperation with the rotating assembly 23, so that the rotating assembly 23 can drive the clutch rotating block 31 to rotate along a first rotation direction R1. The latch 33 is movably arranged on the clutch rotating block 31 and can extend into the transmission hole 231, so that the rotating assembly 23 can drive the clutch rotating block 31 to rotate along a second rotation direction R2 opposite to the first rotation direction R1, and the clutch rotating block 31 has a first abutting portion 3153 and a second abutting portion 3155 which are spaced along the circumference. The elastic member 40 is arranged on the housing 10, the elastic member 40 has a first elastic arm 42 and a second elastic arm 44, the first elastic arm 42 abuts against or separates from the first abutting portion 3153, and the second elastic arm 44 abuts against or separates from the second abutting portion 3155, when the first elastic arm 42 abuts against the first abutting portion 3153 and the second elastic arm 44 abuts against the second abutting portion 3155, the latch 33 corresponds to the transmission hole 231.

[0040] When the handle is rotated to drive the clutch block 31 to rotate along the first rotation direction R1, the first abutting portion 3153 abuts against the first elastic arm 42 to deform the first elastic arm 42, and after the force on the door handle 21 is removed, the first elastic arm 42 returns and provides a counterforce to the clutch block 31, so that the clutch block 31 rotates along the second rotation direction R2, and when the second elastic arm 44 abuts against the second abutting portion 3155, the clutch block 31 returns to the normal position, at which time the bolt 33 corresponds to the transmission hole 231. When the door handle 21 is rotated to drive the clutch block 31 to rotate along the second rotation direction R2, the second abutting portion 3155 abuts against the second elastic arm 44 to deform the second elastic arm 44, and after the force on the door handle 21 is removed, the second elastic arm 44 returns and provides a counterforce to the clutch block 31, so that the clutch block 31 rotates along the first rotation direction R1, and when the first elastic arm 42 abuts against the first abutting portion 3153, the clutch block 31 also returns to the normal position. Through the abutment of the first elastic arm 42 of the elastic member 40 and the first abutting portion 3153 and the abutment of the second elastic arm 44 and the second abutting portion 3155, the clutch block 31 can return to the normal position under the action of the first elastic arm 42 or the second elastic arm 44 after rotating a certain angle, so that the bolt 33 can extend into the transmission hole 231, and at this time the clutch block 31 can be driven by the rotating assembly 23 to rotate along the second rotation direction R2, and the locking of the lock body can be realized by pressing down the door handle 21, avoiding the situation that the bolt 33 cannot extend into the transmission hole 231 due to the misalignment of the bolt 33 and the transmission hole 231, and avoiding the situation that the door handle 21 cannot be pressed down to unlock.

[0041] It should be noted that, taking the perspective in Figure 3 as an example, the first rotation direction R1 of the present application is counterclockwise. The second rotation direction R2 is clockwise.

[0042] Please refer to Figure 6 , specifically, the shell 10 is generally a hollow cuboid structure. The shell 10 includes a bottom plate 11, a cover plate 13 and a surrounding plate 15, the bottom plate 11 and the cover plate 13 are oppositely arranged, and the surrounding plate 15 is connected between the bottom plate 11 and the cover plate 13. It can be understood that the surrounding plate 15 includes four parts connected head to tail, and each part is connected with the bottom plate 11 and the cover plate 13. The shell 10 has a length direction X, a width direction Y and a height direction Z, wherein the height direction Z is consistent with the axial direction of the rotating assembly 23. The cover plate 13 has a through hole 132, so that a tool can extend into the inside of the shell 10 from the cover plate 13.

[0043] Please refer to Figures 7 to 9The clutch rotating block 31 is rotatably arranged on the bottom plate 11. The clutch rotating block 31 is provided with a mounting hole 3151 in the radial direction. The latch 33 is movably arranged in the mounting hole 3151 and can extend or retract relative to the mounting hole 3151. When the latch 33 extends, it can extend into the transmission hole 231, so that the handle assembly 20 can drive the clutch rotating block 31 to rotate in the second rotation direction R2. When the latch 33 retracts, it cannot extend into the transmission hole 231, and the handle assembly 20 cannot drive the clutch rotating block 31 to rotate in the second rotation direction R2. At this time, the lower handle cannot be unlocked.

[0044] The latch 33 has a head portion 332 and a rod portion 334 connected thereto. The head portion 332 is arranged at one end of the rod portion 334 away from the transmission hole 231, and the diameter of the head portion 332 is greater than that of the rod portion 334. The clutch assembly 30 further comprises a spring 35. The mounting hole 3151 is a stepped hole, and the spring 35 is arranged between the step of the mounting hole 3151 and the head portion 332. When external force presses against the head portion 332 of the latch 33, the rod portion 334 of the latch 33 extends out of the mounting hole 3151 and can enter the transmission hole 231. When the external force acting on the head portion 332 is removed, the rod portion 334 retracts under the action of the spring 35, so that the rod portion 334 retracts into the mounting hole 3151. In this way, the latch 33 is movably arranged in the mounting hole 3151.

[0045] The first abutting portion 3153 has a first abutting surface 3154 abutting against the first elastic arm 42, and the second abutting portion 3155 has a second abutting surface 3156 abutting against the second elastic arm 44. The angle between the first abutting surface 3154 and the center axis of the mounting hole 3151 is equal to the angle between the second abutting surface 3156 and the center axis of the mounting hole 3151, that is, the mounting hole 3151 is located at the circumferential middle position of the first abutting portion 3153 and the second abutting portion 3155, so that when the clutch assembly 30 is reversed, the mounting hole 3151 extends substantially along the length direction X of the housing 10, which facilitates the pushing of the latch 33 into the transmission hole 231.

[0046] Please continue to refer to Figures 7 to 9The shell 10 further comprises a first limiting plate 16 and a second limiting plate 17, which are spaced apart along the width direction Y of the shell 10 and are both axially protruded from the bottom plate 11, i.e., the first limiting plate 16 and the second limiting plate 17 both extend along the height direction Z of the shell 10. When the first elastic arm 42 abuts against the first abutting portion 3153 and the second elastic arm 44 abuts against the second abutting portion 3155, the first limiting plate 16 abuts against the first elastic arm 42 and the second limiting plate 17 abuts against the second elastic arm 44, so as to limit the elastic member 40 and realize accurate installation of the elastic member 40. The first limiting plate 16 abuts against the first elastic arm 42 and the first abutting portion 3153 is located on the side of the first limiting plate 16 away from the bottom plate 11, so that the first elastic arm 42 can abut against the first abutting portion 3153. The second limiting plate 17 abuts against the second elastic arm 44 and the second abutting portion 3155 is located on the side of the second limiting plate 17 away from the bottom plate 11, so that the second elastic arm 44 can abut against the second abutting portion 3155, which further facilitates the return of the clutching rotating block 31 to the original position under the action of the first elastic arm 42 or the second elastic arm 44 after rotating by a certain angle.

[0047] Please refer to Figure 6 、 Figure 8 and Figure 10 , the rotating assembly 23 is rotatably arranged on the bottom plate 11. The rotating assembly 23 comprises a handle rod 233 and stacked first and second rotating plates 235 and 237, the first rotating plate 235 is closer to the bottom plate 11 than the second rotating plate 237. The handle rod 233 is arranged through the bottom plate 11 and is fixedly connected with the second rotating plate 237. The handle rod 233 is connected with the door handle 21, so that the door handle 21 can drive the second rotating plate 237 to rotate through the handle rod 233. The first rotating plate 235 is provided with a connecting hole 2351, the second rotating plate 237 is provided with first and second avoiding grooves 2371 and 2373 at two ends opposite in the radial direction, respectively, and the rotating assembly 23 further comprises a fastener 239, which is arranged through one of the first and second avoiding grooves 2371 and 2373 and is connected with the hole wall of the connecting hole 2351, i.e., the fastener 239 is arranged through one of the first and second avoiding grooves 2371 and 2373 and is connected with the first rotating plate 235, so that when the door handle 21 drives the second rotating plate 237 to rotate, the groove wall of one of the first and second avoiding grooves 2371 and 2373 can abut against the fastener 239, thereby driving the first rotating plate 235 connected with the fastener 239 to rotate. The fastener 239 corresponds to the position of the through hole 132 on the cover plate 13, so that a tool (such as a screwdriver) can be inserted into the shell 10 from the through hole 132 to loosen or tighten the fastener 239.

[0048] The clutch rotating block 31 is provided with an avoiding gap 312 corresponding to one of the first avoiding slot 2371 and the second avoiding slot 2373, so that the fastener 239 can be screwed with the connecting hole 2351 through the avoiding gap 312, one of the first avoiding slot 2371 and the second avoiding slot 2373, so that the user can realize the tightening or loosening operation of the fastener 239 without removing the clutch rotating block 31, which reduces the operation difficulty.

[0049] Since the first avoiding slot 2371 and the second avoiding slot 2373 are arranged at the two ends of the second rotating plate 237 in the radial direction, the fastener 239 is arranged in one of the first avoiding slot 2371 and the second avoiding slot 2373, so that when the second rotating plate 237 rotates 180°, the fastener 239 can be arranged in the other of the first avoiding slot 2371 and the second avoiding slot 2373 to be connected with the first rotating plate 235. Since the door handle 21 drives the second rotating plate 237 to rotate through the handle rod 233, when the second rotating plate 237 rotates 180°, the door handle 21 also rotates 180°, that is, only need to insert the tool into the through hole 132 on the cover plate 13 and remove the fastener 239, and then rotate the door handle 21 by 180° to realize the reversing of the door handle 21, without disassembling the shell 10 and other structures of the handle device 1, avoiding the problem of unscrewed or falling off of the screw caused by disassembling the shell 10, and without distinguishing the position of the fastener 239, which is convenient for the user to use.

[0050] The first rotating plate 235 is provided with a third avoiding slot 2352, and the other of the first avoiding slot 2371 and the second avoiding slot 2373 corresponds to the third avoiding slot 2352 and forms a transmission hole 231 with the third avoiding slot 2352. For example, when the fastener 239 is arranged in the first avoiding slot 2371, the second avoiding slot 2373 corresponds to the third avoiding slot 2352, and the second avoiding slot 2373 forms the transmission hole 231 with the third avoiding slot 2352. For another example, when the fastener 239 is arranged in the second avoiding slot 2373, the first avoiding slot 2371 corresponds to the third avoiding slot 2352, and the first avoiding slot 2371 forms the transmission hole 231 with the third avoiding slot 2352. When the bolt 33 extends into the transmission hole 231, the bolt 33 can abut against the slot wall of the third avoiding slot 2352 and the slot wall of the other of the first avoiding slot 2371 and the second avoiding slot 2373, that is, the bolt 33 can abut against the first rotating plate 235 and the second rotating plate 237 at the same time when the bolt 33 extends into the transmission hole 231, so as to ensure sufficient strength and avoid the bending of the single rotating plate when the single rotating plate abuts against the bolt 33 as far as possible. In addition, the bolt 33 can abut against the slot wall of the third avoiding slot 2352 and the slot wall of the other of the first avoiding slot 2371 and the second avoiding slot 2373, so as to increase the thickness of the hole wall of the transmission hole 231 along the axial direction, and make the cooperation between the bolt 33 and the transmission hole 231 more stable, so that the rotating assembly 23 can drive the clutch block 31 to rotate along the second rotation direction R2 more stably.

[0051] Please continue to refer to Figure 2 and Figure 10 The first rotating plate 235 includes a plate body 2353 sleeved on the handle rod 233, and a first pushing rod 2354 and a second pushing rod 2355 protruding from the plate body 2353 in the direction of the bottom plate 11, wherein the plate body 2353 is substantially annular. The first pushing rod 2354 and the second pushing rod 2355 both have a gap with the bottom plate 11 of the shell 10, so as to avoid scratching the bottom plate 11 when the first rotating plate 235 rotates, thereby avoiding damage to the shell 10 and unnecessary noise. The first pushing rod 2354 and the second pushing rod 2355 are respectively arranged at two ends of the first rotating plate 235 along the radial direction, the first pushing rod 2354 can abut against the first elastic arm 42, and the second pushing rod 2355 can abut against the second elastic arm 44, so that the elastic member 40 can drive the first rotating plate 235 to return to the normal position. For example, when the first rotating plate 235 rotates along the first rotation direction R1, the first pushing rod 2354 abuts against the first elastic arm 42, and the first elastic arm 42 can also generate a reaction force on the first pushing rod 2354, so that the first rotating plate 235 rotates along the second rotation direction R2, and the first rotating plate 235 returns to the normal position.

[0052] Please continue to refer to Figure 7 and Figure 8The clutching rotating block 31 comprises a top plate 313, an arc-shaped side plate 315 connected to the top plate 313, and a boss 317 protruding from the top plate 313. The top plate 313 is arranged on the side of the second rotating plate 237 away from the bottom plate 11, i.e., the top plate 313 covers the first rotating plate 235 and the second rotating plate 237. The boss 317 can be inserted by the lock core lever, so that the rotation of the clutching rotating block 31 can drive the lock core lever to rotate, so as to realize the locking or unlocking of the lock body. The arc-shaped side plate 315 is arranged on the side of the first limiting plate 16 away from the bottom plate 11, and the arc-shaped side plate 315 is provided with a first abutting portion 3153 and a second abutting portion 3155. The first abutting portion 3153 is arranged on the side of the first limiting plate 16 away from the bottom plate 11, and the second abutting portion 3155 is arranged on the side of the second limiting plate 17 away from the bottom plate 11. The arc-shaped side plate 315 is provided with a mounting hole 3151, and the latch 33 is arranged in the mounting hole 3151 of the arc-shaped side plate 315.

[0053] The arc-shaped side plate 315 is arranged on the rotating path of the second rotating plate 237, so that the second rotating plate 237 can drive the arc-shaped side plate 315 to rotate along the first rotation direction R1 when the second rotating plate 237 rotates along the first rotation direction R1. Specifically, the inner wall of the arc-shaped side plate 315 is provided with an axial extending stop surface 3157, and the second rotating plate 237 is provided with a radial protruding protrusion 2375. The protrusion 2375 is in abutment or separation with the stop surface 3157. For example, when the second rotating plate 237 rotates along the first rotation direction R1, the protrusion 2375 is in abutment with the stop surface 3157 to drive the clutching rotating block 31 to rotate along the first rotation direction R1. When the second rotating plate 237 rotates along the second rotation direction R2, the protrusion 2375 is separated from the stop surface 3157. At this time, the latch 33 needs to be inserted into the transmission hole 231, and the second rotating plate 237 can drive the clutching rotating block 31 to rotate along the second rotation direction R2.

[0054] Please refer to Figures 10 to 14The shell 10 further comprises a first side plate 151 and a second side plate 153, which are spaced apart along the width direction Y of the shell 10 and are both connected to the bottom plate 11. The first side plate 151 and the second side plate 153 are both part of the enclosure 15. In the illustrated embodiment, the first side plate 151 is spaced apart from the first limiting plate 16 along the length direction X of the shell 10, and the second side plate 153 is spaced apart from the second limiting plate 17 along the length direction X of the shell 10. The first rotating plate 235 further comprises a flange 2356 protruding radially from the plate body 2353 and a limiting rod 2357 extending from the flange 2356 toward the bottom plate 11, the flange 2356 being disposed between the first actuating rod 2354 and the second actuating rod 2355. The flange 2356 is provided with a part of the connecting hole 2351, and the plate body 2353 is provided with another part of the connecting hole 2351, i.e., the connecting hole 2351 is provided at the connected part of the flange 2356 of the plate body 2353. The limiting rod 2357 is disposed on the side of the flange 2356 away from the plate body 2353, and is disposed between the first side plate 151 and the second side plate 153 and can selectively abut against the first side plate 151 or the second side plate 153, so that the first side plate 151 and the second side plate 153 can limit the rotation angle of the first rotating plate 235.

[0055] The limiting rod 2357 comprises a first limiting portion 2358 and a second limiting portion 2359 arranged side by side, the length of the first limiting portion 2358 being greater than the length of the second limiting portion 2359. The first limiting portion 2358 can abut against the first side plate 151, and specifically, when the first rotating plate 235 rotates in the second rotation direction R2, the first limiting portion 2358 abuts against the first side plate 151 to limit the rotation angle of the first rotating plate 235 in the second rotation direction R2, thereby limiting the rotation angle of the door handle 21 in the second rotation direction R2. The second side plate 153 is provided with an avoidance hole 18 at the joint with the bottom plate 11, and the second limiting portion 2359 can abut against the second side plate 153, and when the second limiting portion 2359 abuts against the second side plate 153, at least part of the first limiting portion 2358 extends into the avoidance hole 18. Specifically, when the first rotating plate 235 rotates in the first rotation direction R1, the second limiting portion 2359 abuts against the second side plate 153 to limit the rotation angle of the first rotating plate 235 in the first rotation direction R1, thereby limiting the rotation angle of the door handle 21 in the first rotation direction R1.

[0056] It should be noted that the joint of the second side plate 153 and the bottom plate 11 is provided with a wire slot (not shown in the figure) for the wire of the cable. Specifically, the wire slot is arranged on the side of the bottom plate 11 away from the cover plate 13. Since the joint of the second side plate 153 and the bottom plate 11 is provided with a wire slot, in order to ensure the sufficient strength of the shell 10, the shell 10 needs to have a certain thickness, so that the joint of the second side plate 153 and the bottom plate 11 needs to be arched towards the inside of the shell 10, and the relief hole 18 is arranged in the arched part.

[0057] Please continue to refer to Figure 9 and Figure 10 The bottom plate 11 has a first stop plate 112 and a second stop plate 114 extending towards the first rotating plate 235, the first stop plate 112 is arranged on the rotating path of the first driving rod 2354, so that the first driving rod 2354 can abut against the first stop plate 112, specifically, when the first rotating plate 235 rotates along the second rotation direction R2, the first driving rod 2354 abuts against the first stop plate 112 to limit the rotation angle of the first rotating plate 235 along the second rotation direction R2. The second stop plate 114 is arranged on the rotating path of the second driving rod 2355, so that the second driving rod 2355 can abut against the second stop plate 114, specifically, when the first rotating plate 235 rotates along the first rotation direction R1, the second driving rod 2355 abuts against the second stop plate 114 to limit the rotation angle of the first rotating plate 235 along the first rotation direction R1. When the limiting rod 2357 abuts against the first side plate 151, the first driving rod 2354 abuts against the first stop plate 112, that is, when the first rotating plate 235 rotates along the second rotation direction R2, the limiting rod 2357 abuts against the first side plate 151 at the same time, and the first driving rod 2354 abuts against the first stop plate 112, so that when the first rotating plate 235 rotates along the second rotation direction R2, the first stop plate 112 can share the extrusion force of the first rotating plate 235, thereby reducing the acting force on the first side plate 151 and reducing the probability of deformation of the first side plate 151 due to extrusion. When the limiting rod 2357 abuts against the second side plate 153, the second driving rod 2355 abuts against the second stop plate 114, that is, when the first rotating plate 235 rotates along the first rotation direction R1, the limiting rod 2357 abuts against the second side plate 153 at the same time, and the second driving rod 2355 abuts against the second stop plate 114, so that when the first rotating plate 235 rotates along the first rotation direction R1, the second stop plate 114 can share the extrusion force of the first rotating plate 235, thereby reducing the acting force on the second side plate 153 and reducing the probability of deformation of the second side plate 153 due to extrusion.

[0058] The elastic member 40 further comprises a body portion 46, the first elastic arm 42 and the second elastic arm 44 extend from the body portion 46 in different directions. The body portion 46 is arranged on the bottom plate 11 and sleeved on the portion of the handle rod 233 away from the door handle 21. The body portion 46 is in a spiral structure. The first elastic arm 42 extends radially from the body portion 46 and then extends axially, and the second elastic arm 44 extends radially from the body portion 46 and then extends axially. In the embodiment shown in the figure, the elastic member 40 is a torsion spring.

[0059] The handle device 1 further comprises a sleeve 50 sleeved on the handle rod 233. Specifically, in the radial direction, the sleeve 50 is arranged between the body portion 46 and the handle rod 233, and in the axial direction, the sleeve 50 is arranged between the bottom plate 11 and the plate body 2353 of the first rotating plate 235 to support the first rotating plate 235. It should be noted that the height of the sleeve 50 is greater than the height of the limiting rod 2357, the first actuating rod 2354 and the second actuating rod 2355, so that when the first rotating plate 235 rotates, the limiting rod 2357, the first actuating rod 2354 and the second actuating rod 2355 will not scratch the bottom plate 11.

[0060] The handle device 1 further comprises a motor 60 and a push rod 70, both of which are arranged in the housing 10, and the motor 60 can drive the push rod 70 to extend or retract. When the motor 60 drives the push rod 70 to extend, the push rod 70 can abut against the latch 33 and push the latch 33 into the transmission hole 231.

[0061] In summary, the handle device 1 provided by the present application, the first elastic arm 42 of the elastic member 40 abuts against or separates from the first abutting portion 3153, the second elastic arm 44 of the elastic member 40 abuts against or separates from the second abutting portion 3155, when the first elastic arm 42 abuts against the first abutting portion 3153 and the second elastic arm 44 abuts against the second abutting portion 3155, the latch 33 corresponds to the transmission hole 231, so that the latch 33 can extend into the transmission hole 231, at this time the clutch block 31 can be driven by the rotating assembly 23 to rotate in the second rotation direction R2, and the unlocking of the lock body is realized, avoiding the situation that the latch 33 and the transmission hole 231 cannot be aligned and cannot extend into the transmission hole 231, thus avoiding the situation that the handle cannot be unlocked by being pressed down.
