Description

Technical Field

[0001] This application relates to the field of lock technology, and more particularly to a panel lock. Background Technology

[0002] Panel locks are widely used in various industries, such as shipbuilding, generator sets, HVAC, and RVs. Panel locks typically have a foldable handle that is installed in a recess in the panel. This handle can be pulled up from the recess to turn and unlock or lock. The handle also usually has a folded state where it is flush with the panel body and nestled within the recess.

[0003] Related technologies describe panel locks such as those in US5,526,660, US6,454,321B1, US4,706,478, and US7,748,246B1, in which the handle is free and cannot be locked in the closed position; and in US6,532,778B2, US6,952,940B2, US8,770,635B2, and US2004 / 0007031A1, the handle can be free or optionally locked by a cylinder connected to the housing.

[0004] Existing panel locks typically suffer from the following technical problems: After the handle is folded down, it remains free unless further locked with a key via a lock cylinder or padlock. This necessitates the use of multiple latches to operate multiple panels for locking, increasing the time required to complete the entire locking process. Particularly when the panel lock is mounted on a moving vehicle, the handle is prone to noise due to its inability to fully lock. In extreme cases, such as high acceleration, the handle may be fully lifted due to inertia, potentially causing adverse consequences, such as the latching mechanism detaching completely from the frame and releasing. This instability can ultimately lead to premature system failure. For applications requiring handle folding and compression to seal the panel and prevent water ingress, the compression loss caused by the handle lifting can accelerate the failure of weather-sensitive components within the chamber. Furthermore, once the handle is fully lifted, whether the panel lock is mounted on static equipment or a moving vehicle, it poses a serious safety hazard to passing objects and personnel. Summary of the Invention

[0005] In view of this, the purpose of this application is to provide a panel lock.

[0006] Based on the above objectives, this application provides a panel lock, including a housing, a pivot, a latch, and a handle. The pivot is rotatably mounted on the housing, and the latch is connected to the pivot and extends and retracts with the pivot to achieve unlocking and locking operations. The handle is rotatably mounted on the pivot, and during rotation about a first axis perpendicular to the pivot, the handle has a first position folded relative to the housing and a second position raised at a certain angle relative to the housing. The handle also has a latch groove and a guide portion located on one side of the latch groove.

[0007] The panel lock also includes a latch hook and a first elastic element. The latch hook is rotatably mounted on the housing. The first elastic element is disposed between the latch hook and the housing. When the handle is in the first position, the latch hook is driven by the first elastic element to press against the latch groove to prevent the handle from disengaging from the first position.

[0008] During the movement of the handle from the second position to the first position, the guide part opens the latch hook and guides the latch hook into the latch groove;

[0009] The locking hook has a protrusion around the rotation position, and an unlocking camshaft is installed on the housing. During rotation, the unlocking camshaft drives the locking hook to unlock the handle through the protrusion. The unlocking camshaft has an exposed external interface for the installation of external modules, which enhances the expandability of the panel lock.

[0010] The panel lock provided in this application embodiment can automatically lock the handle simultaneously as it moves from the unfolded state to the folded state, thereby preventing the handle from coming off again and ensuring the reliability and security of the panel lock during use. Furthermore, the locking of the handle is achieved synchronously during the folding process, eliminating the need for other locking actions and offering good convenience.

[0011] In one possible implementation, the latch hook has a third position, a fourth position, and a fifth position during movement. In the third position, the latch hook is pressed into the latch groove by the first elastic element, locking the handle in the first position. In the fourth position, the latch hook disengages from the latch groove, allowing the handle to disengage from the first position. When the handle is lifted, the latch hook is driven by the first elastic element to move from the fourth position to the fifth position, wherein the fifth position of the latch hook is the same as the third position, except that the latch hook is no longer in the latch groove and is located below it. During the movement of the handle from the second position to the first position, the guide portion opens the latch hook and guides it to move back from the fifth position to the third position.

[0012] In one possible implementation, the panel lock further includes an unlocking element and a transmission mechanism connected to the unlocking element. The unlocking element is movably mounted on the housing, and the movable unlocking element drives the locking tongue hook to move from the third position to the fourth position via the transmission mechanism.

[0013] In one possible implementation, the unlocking element includes a lock cylinder that rotates about an axis under key drive, and the transmission mechanism includes a lock cylinder follower, a first slider, and a first motion conversion mechanism; the lock cylinder follower rotates with the lock cylinder, the first slider is slidably mounted on the housing, and the first motion conversion mechanism is disposed between the lock cylinder follower and the first slider; during the rotation of the lock cylinder follower, the first slider is driven to slide through the first motion conversion mechanism, and during the sliding process, the first slider drives the bolt hook to move from the third position to the fourth position.

[0014] In one possible implementation, the latch hook includes a hook-shaped portion and a protrusion that protrude around the rotational position, the hook-shaped portion engaging with the latch groove, and the first slider pushing the protrusion during sliding.

[0015] In one possible implementation, the transmission mechanism further includes a second elastic element, under the action of the second elastic element, the first slider is positioned away from the locking hook.

[0016] In one possible implementation, the first motion conversion mechanism includes a rotating protrusion provided on either the lock cylinder follower or the first slider, and a mating groove provided on the other, wherein the rotating protrusion and the mating groove cooperate to achieve rotational-linear motion conversion.

[0017] In one possible implementation, the first motion conversion mechanism includes a gear disposed on either the lock cylinder follower or the first slider, and a rack disposed on the other and slidably engaged with the gear; the gear and the rack cooperate with each other to achieve rotational-linear motion conversion.

[0018] In one possible implementation, the unlocking element includes an unlocking button slidably mounted on the housing; the transmission mechanism includes a second slider and a second motion conversion mechanism; the second slider is slidably mounted on the housing, and the second motion conversion mechanism is disposed between the unlocking button and the second slider; the unlocking button drives the second slider to slide via the second motion conversion mechanism; during the sliding process, the second slider drives the locking tongue hook to move from the third position to the fourth position.

[0019] In one possible implementation, the second motion conversion mechanism includes a first driving ramp disposed on the second slider and a driving end disposed on the unlock button, wherein the first driving ramp and the driving end slide in contact to achieve the conversion of the unlock button and the second slider sliding in different directions.

[0020] In one possible implementation, a lock cylinder that rotates about an axis under key actuation is included, and the locking element prevents the unlock button from sliding when the lock cylinder rotates to a target position.

[0021] In one possible implementation, at least one of the handle and the housing is provided with a pop-out device that drives the handle, disengaged from the latch hook, to a middle position, the middle position being located between the first position and the second position.

[0022] In one possible implementation, the ejection device includes a first ejection mechanism, which includes a mounting base disposed on the handle, a third elastic element, and a spring cap; it also includes an action protrusion disposed on the housing; the spring cap is slidably disposed on the mounting base, the third elastic element is disposed between the spring cap and the mounting base, and drives the spring cap to move to an outer position of the mounting base; the action protrusion abuts against the spring cap when the handle moves to the first position.

[0023] In one possible implementation, the ejection device includes a second ejection mechanism, which includes a spring bracket rotatably mounted on the handle and an ejection torsion spring mounted on the spring bracket. One end of the ejection torsion spring abuts against the handle, and the other end abuts against the spring bracket. When the handle moves to the first position, the elastic bracket abuts against the pivot and compresses the ejection torsion spring.

[0024] In one possible implementation, when the handle in the second position rotates around the pivot, it drives the pivot to rotate the latch, moving it from the locked position to the unlocked position, and vice versa, to achieve unlocking and locking operations. Attached Figure Description

Therefore, they should not be construed as limiting the scope of protection of the present invention. When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0057] Figure 1 This is a schematic diagram of the structure of a panel lock provided in an embodiment of this application, as shown below. Figure 1 As shown, the panel lock includes a housing 1, a first locking component 2, a handle 3, a second locking component 4, and a first unlocking component 5. The panel lock has two sides: a front and a back. The front side faces the user, who operates the panel lock from the front. After installation, the back side faces the door. The housing 1 has a first groove 101 on the front side, and a second groove 104 at the bottom of the first groove.

[0058] The first locking assembly 2 is used to lock and unlock the door on which the panel lock is installed. The first locking assembly 2 includes a first rotating shaft 201 and a first locking bolt 202. The first rotating shaft 201 is rotatably mounted on the housing 1 about its longitudinal axis and passes through the housing 1. The first locking bolt 202 is connected to the portion of the first rotating shaft 201 located on the back of the housing 1. The first locking assembly 2 locks and unlocks the door on which the panel lock is installed by rotating the first locking bolt 202.

[0059] The handle 3 is mounted on the portion of the first rotating shaft 201 located on the front of the housing 1, and is rotatably mounted on the end of the first rotating shaft 201 about a first axis 303, which is perpendicular to the first rotating shaft 201 and its longitudinal axis. The handle 3 can rotate relative to the first rotating shaft 201 about the first axis 303, or it can rotate together with the first rotating shaft 201 about its longitudinal axis. Referring to Figure 2, during rotation about the first axis 303, the handle 3 has a first position folded into the first groove 101 (e.g., ...). Figure 2a ), and a second position raised at a certain angle relative to the housing 1 (e.g. Figure 2b The handle 3 in the second position can be collinear with the first rotating shaft 201 to facilitate the twisting operation of the handle 3 on the first rotating shaft 201.

[0060] refer to Figure 1 and Figure 3 The first latch 202 can be an adjustable latch, which includes a first latch slide 203 and a first latch shaft 204. The first latch shaft 204 is vertically mounted on the first latch slide 203. The first latch slide 203 includes a slide body 2031 and a fixing ring 2032 sleeved on the first rotating shaft 201. The first latch slide 203 is used to adjust the installation position of the first latch shaft 204 in the length direction of the first rotating shaft 201. This design allows the panel lock to adapt to door thicknesses and increases its versatility.

[0061] In one possible implementation, the first locking tongue slide 203 includes a threaded shaft mounted on the slide body 2031. One end of the first locking tongue shaft 204 on the slide body 2031 has a thread that mates with the threaded shaft, allowing it to move along the first locking tongue slide 203 under the influence of the rotating threaded shaft. When the position of the first locking tongue shaft 204 needs to be adjusted, the threaded shaft can be turned to easily adjust its position.

[0062] During the use of the panel lock, the user grasps the handle 3, lifting it from the first position folded in the first groove 101 to a second position at a certain angle relative to the housing 1. Then, the user rotates the handle 3 to drive the first rotating shaft 201 to rotate, thereby driving the first locking tongue 202 to rotate and switch between locking and unlocking. To facilitate user operation, the handle 3 can be any structure that is convenient to grip and rotate, such as T-shaped or L-shaped. This embodiment uses a T-shaped handle as an example for explanation.

[0063] Figure 4 Please refer to the schematic diagram of the handle provided in the embodiment of this application. Figures 1 to 4The handle 3 has a T-shaped structure, including a first handle portion 31 and a second handle portion 32. Both the first handle portion 31 and the second handle portion 32 are elongated structures. The length direction of the first handle portion 31 is perpendicular to the first axis 303. One end of the first handle portion 31 along its length direction is provided with a first shaft hole 3031, and it is rotatably mounted to the first rotating shaft 201 through the first shaft hole 3031 and the first axis 303 passing through the first shaft hole 3031. The other end of the first handle portion 31 along its length direction is connected to the second handle portion 32. The length direction of the second handle portion 32 is perpendicular to the length direction of the first handle portion 31, and the first handle portion 31 is connected to the middle position of the second handle portion 32, thus forming a T-shaped structure. For easy hand operation, the second handle portion 32 can be bent with a certain curvature along its length direction.

[0064] The handle 3 has an inner side and an outer side. In this paper, the side of the handle 3 closer to the housing 1 during the movement between the first position and the second position is defined as the inner side, and the side opposite to the inner side is defined as the outer side.

[0065] The handle 3 has a latch groove 301 and a guide portion 302. The latch groove 301 has an opening that extends outward, and the direction of the opening is substantially parallel to the extension direction of the first handle portion. The guide portion 302 is located on the side of the latch groove 301 near the housing, that is, the portion between the edge of the latch groove 301 and the inner side of the handle 3 is the guide portion 302. During the movement of the handle 3 from the second position to the first position, the guide portion 302 can push the latch hook 401 to overcome the movement of the elastic element and guide the latch hook 401 to the latch groove 301 (see description below).

[0066] The second locking assembly 4 is used to lock the handle 3 in the first position. It includes a locking hook 401 and a first elastic element 402. The locking hook 401 is connected to the second pivot 10 (see reference). Figures 6a to 6c It can be rotatably mounted on the housing 1, with the second rotating shaft 10 perpendicular to the first rotating shaft 201. It should be noted that since the position of the first axis 303 changes during the rotation of the first rotating shaft 201, when the handle 3 is in the first position, the first axis 303 will be parallel to the second rotating shaft 10.

[0067] The first elastic element 402 is disposed between the locking hook 401 and the housing 1. Optionally, the first elastic element 402 can be a torsion spring sleeved on the second rotating shaft 10, with one end of the torsion spring connected to the housing 1 and the other end connected to the locking hook 401. Under the action of the torsion spring, the locking hook 401 rotates around the second rotating shaft 10.

[0068] Figure 5 This is a schematic diagram of the structure of a locking hook provided in an embodiment of this application, as shown below. Figure 5As shown, the locking hook 401 is a hook-shaped structure, including a second shaft hole 4013 for mounting the second rotating shaft 10, and a first protrusion 4017, a second protrusion 4016 and a third protrusion 4014 arranged around the position of the second shaft hole 4013. It also includes a hook-shaped part 4018 connected to the first protrusion 4017. The first protrusion 4017, the second protrusion 4016 and the third protrusion 4014 are all outward protruding structures extending in the radial direction of the second shaft hole 4013, and are basically evenly distributed on the outer periphery of the second shaft hole 4013.

[0069] The hook-shaped portion 4018 extends from the top of the first protrusion 4017 toward the side where the second protrusion 4016 is located, thereby forming a hook-shaped structure. The hook-shaped portion 4018 also includes a first side surface 4011 and a second side surface 4012 forming the hook-shaped portion 4018, wherein the first side surface 4011 is closer to the second protrusion 4016 than the second side surface 4012. That is, relative to the hook-shaped structure, the first side surface 4011 is the inner side surface, and the second side surface 4012 is the outer side surface. A mounting groove 4015 is provided on one side of the third protrusion 4014, which is used to cooperate with the torsion spring (first elastic member 402).

[0070] The locking hook 401 is rotatably mounted on the housing 1, and has a third, fourth, and fifth position during rotation. Figures 6a to 6c Please refer to the structural diagrams showing the latch hook in different states in the panel lock provided in the embodiments of this application. Figure 6a The first elastic element 402 is disposed between the locking hook 401 and the housing 1, driving the locking hook 401 to move to the third position. In the third position, the hook-shaped part 4018 of the locking hook 401 is pressed into the locking groove 301 by the first elastic element 402, so that the handle 3 is fixedly held in the folded first position.

[0071] Please refer to Figure 6b The locking hook 401, which is in the third position, rotates clockwise around the second pivot 10 until it disengages from the locking groove 301, so that the handle 3 can disengage from the first position and move freely between the first and second positions. The position of the locking hook 401 at this time is defined as the fourth position.

[0072] Please refer to Figure 6c When the handle 3 is lifted from the first position, the locking hook 401 moves counterclockwise around the axis to the fifth position under the drive of the first elastic element 402. At this time, the fifth position of the locking hook 401 is the same as the third position, except that the locking hook 401 is no longer in the locking groove 301 and is located below the locking groove 301.

[0073] During use, after the handle 3 in the panel lock completes its operation, it needs to be rotated and folded from the second position to the first position. During the movement from the second position to the first position, before the handle 3 contacts the latch hook 401, the latch hook 401 remains in the fifth position under the drive of the first elastic element 402. After the handle 3 contacts the latch hook 401, the guide part 302 of the handle 3 pushes the latch hook 401. Under the force of the guide part 302 of the handle 3, the latch hook 401 overcomes the elastic force of the first elastic element 402 and rotates in the opposite direction to the fourth position. When the handle 3 moves to the first position, the latch hook 401 moves through the guide part 302 to a position where it can enter the latch groove 301. Driven by the first elastic element 402, the latch hook 401 extends into the latch groove 301, completing the locking of the handle 3.

[0074] Figure 7 Figure 6 shows a schematic diagram illustrating the function of the latch hook and the handle. Figure 7 As shown, the hook-shaped part 4018 of the locking hook 401 extends into the locking groove 301 of the handle 3. By means of the cooperation between the groove wall 3011 of the locking groove 301 and the first side surface 4011 of the hook-shaped part 4018, the locking hook 401 locks the handle 3.

[0075] During the reverse rotation of the latch hook 401 by the handle 3, the guide portion 302 presses against the second side surface 4012 outside the latch hook 401 and moves on the second side surface 4012. Due to the arcuate feature of the second side surface 4012, the guide portion 302 of the handle 3 pushes open the latch hook 401 in the fifth position and drives the latch hook 401 to rotate in the reverse direction while pressing the second side surface 4012. To facilitate better actuation, the guide portion 302 can be designed as an arcuate structure with less resistance to the second side surface 4012 during movement. Similarly, the second side surface 4012 can adopt an arcuate structure to reduce the friction between the guide portion 302 and the second side surface 4012.

[0076] As described above, the panel lock provided in this embodiment can automatically lock the handle 3 during its movement from the second position to the first position, thereby preventing the handle 3 from coming off again and ensuring the reliability and security of the panel lock. Furthermore, the locking of the handle 3 is achieved simultaneously during the folding process, eliminating the need for other locking actions and offering good convenience.

[0077] After the handle 3 is locked by the second locking component 4, it needs to be unlocked if it is needed to be used again. In view of this, the panel lock provided in this application embodiment is provided with an unlocking device. The unlocking device can drive the locking hook 401 to rotate in the opposite direction and move from the third position to the fourth position, so that the hook-shaped part 4018 of the locking hook 401 disengages from the locking groove 301 of the handle 3, thereby realizing the unlocking of the handle 3 by the locking hook 401.

[0078] In the panel lock provided in this application embodiment, the handle 3 is locked by cooperating with the second locking component 4, and the handle 3 is unlocked by the unlocking device. This design allows the handle 3 to be stably locked in the first groove 101 and the second groove 104 of the housing 1 when not in operation, avoiding the influence of unstable environment on the shaking of the handle 3, enhancing the security of the panel lock, and meeting the requirements of locks under different working conditions; and the unlocking device does not affect the normal use of the panel lock.

[0079] The unlocking device includes a first unlocking component 5, which includes an unlocking element 501 and a transmission mechanism 502 connected to the unlocking element 501. The unlocking element 501 is movably mounted on the housing 1. During its movement, the unlocking element 501 drives the transmission mechanism 502. During its movement, the transmission mechanism 502 acts on the third protrusion 4014 of the latch hook 401. By pushing the third protrusion 4014, the latch hook 401 is driven to rotate in the opposite direction around the axis, causing the latch hook 401 to move to the fourth position, thereby unlocking the latch hook 401. The unlocking element 501 has a control end exposed facing the front of the housing 1, allowing the user to unlock the handle 3 by operating the control end.

[0080] After unlocking handle 3, the user can pull handle 3 up to the second position and rotate handle 3 to drive the first rotating shaft 201 to rotate. The first rotating shaft 201 drives the first locking tongue 202 to rotate, and the rotation of the first locking tongue 202 realizes the switching between the locked and unlocked positions of the panel lock. In one embodiment, when the user pulls handle 3 up from the first position to the second position, the locking tongue moves downward to release the pressure; rotating handle 3 around the first rotating shaft 201 drives the first rotating shaft 201 to rotate and drives the first locking tongue 202 to rotate, so that the first locking tongue 202 disengages to the unlocked position, thereby realizing the switching between the locked and unlocked positions of the panel lock.

[0081] Figure 8 This is a schematic diagram of the structure of the first unlocking component provided in an embodiment of this application. Figure 9 This is a schematic diagram of the structure of the first unlocking component on the back of the housing, as shown below. Figure 8 and Figure 9 As shown, the unlocking component 501 includes a lock cylinder 503, and the transmission mechanism 502 includes a lock cylinder follower 504, a first slider 505, and a first motion conversion mechanism. The lock cylinder 503 is vertically mounted on the front of the housing 1 and can rotate under the action of the key 506. The lock cylinder follower 504 is mounted on the bottom of the lock cylinder 503 and can rotate synchronously with the lock cylinder 503. The first slider 505 is slidably mounted on the housing 1 and contacts the third protrusion 4014 of the latch hook 401 during sliding, and can push the latch hook 401 to move to the fourth position against the force of the first elastic member 402.

[0082] The first motion conversion mechanism is located between the lock cylinder follower 504 and the first slider 505. During the rotation of the lock cylinder follower 504, the first motion conversion mechanism converts the rotation into the sliding of the first slider 505. During the sliding process, the first slider 505 drives the lock tongue hook 401 to move to the fourth position.

[0083] Figure 10 for Figure 8 Schematic diagram of the driven component of the central lock cylinder. Figure 11 for Figure 8 A schematic diagram of the structure of the first slider is shown below. Figures 8 to 11 As shown, the first motion conversion mechanism includes a rotating protrusion 5041 provided on the lock cylinder follower 504 and a mating groove 5051 provided on the first slider 505. The rotating protrusion 5041 and the mating groove 5051 cooperate with each other to realize the rotation-linear motion conversion.

[0084] Obviously, the positions of the rotating protrusion and the mating groove can be interchanged. In addition, the first motion conversion mechanism can be any rotation-to-linear motion conversion mechanism. For example, the first motion conversion mechanism can also include a gear provided on either the lock cylinder follower 504 and the first slider 505, and a rack provided on the other side that slides with the gear; the gear and rack cooperate with each other to realize the rotation-to-linear motion conversion, which will not be listed one by one here.

[0085] Figure 12 A schematic diagram of the working principle of the first unlocking component provided in the embodiments of this application is shown below. Figure 12 As shown, the working principle of the first unlocking component 5 is as follows: the user takes out the matching key 506, inserts it and turns the lock cylinder 503. The lock cylinder follower 504 at the bottom of the lock cylinder 503 rotates accordingly. The lock cylinder follower 504 and the first slider 505 complete the motion conversion through the first motion conversion mechanism, thereby pushing the first slider 505 to slide. During the sliding process, the first slider 505 contacts the third protrusion 4014 of the lock tongue hook 401 and can push the lock tongue hook 401 to overcome the force of the first elastic member 401 and move to the fourth position, thereby unlocking the handle 3.

[0086] The transmission mechanism 502 also includes a reset torsion spring 507, which is sleeved on the lock cylinder follower 504 and is used to provide torque to restore the lock cylinder follower 504 to its initial angle after rotation. Since the lock cylinder 503 and the lock cylinder follower 504 are designed to be linked, the reset torsion spring 507 can restore the released lock cylinder 503 to its initial angle through the lock cylinder follower 504.

[0087] Figure 13 This is a schematic diagram of another first unlocking component provided in an embodiment of this application. Figure 14a and Figure 14b for Figure 13The diagram shown illustrates the working principle of the first unlocking component. Figure 13 , Figure 14a and Figure 14b As shown, in the first unlocking component 5, the unlocking element 501 includes a lock cylinder 503 and an unlocking button 510, and the transmission mechanism 502 includes a second slider 508 and a second motion conversion mechanism.

[0088] The unlock button 510 has a sliding protrusion 5101 on its outer periphery, and slides along the first axis on the housing 1 via the sliding protrusion 5101. The lock cylinder 503 is sleeved inside the unlock button 510, that is, the unlock button 510 is sleeved outside the lock cylinder 503. The lock cylinder 503 and the unlock button 510 can rotate around the central axis parallel to the first rotating shaft 201 in the unlock button 510 through the internal interlocking structure, and slide synchronously with the unlock button 510.

[0089] The lock cylinder 503 has a limiting protrusion 5031 at its bottom, and the housing 1 has a limiting groove 110 corresponding to the limiting protrusion 5031. After the locking cylinder 503 rotates to a preset angle, the limiting protrusion 5031 aligns with the limiting groove 110. Once aligned, the limiting protrusion 5031 can enter the limiting groove 110 and slide along the first axis within it. However, if the limiting protrusion 5031 has not moved to the preset angle, it cannot align with the limiting groove 110 and therefore cannot enter it; the limiting protrusion 5031 is confined above the limiting groove 110. The shapes of the limiting protrusion 5031 and the limiting groove 110 can be elongated, cross-shaped, square, triangular, etc.

[0090] A lock cylinder compression spring 509 is also provided between the bottom of the lock cylinder 503 and the housing 1. The lock cylinder compression spring 509 drives the limiting protrusion 5031 to move to the position where it is disengaged from the limiting groove 110. That is to say, in the process of the limiting protrusion 503 aligning with the limiting groove 110 and entering the limiting groove 110, it is necessary to overcome the elastic force of the lock cylinder compression spring 509.

[0091] The second slider 508 is slidably mounted on the housing 1. During the sliding process, it contacts the third protrusion 4014 of the locking hook 401 and can push the locking hook 401 to move to the fourth position against the elastic force of the first elastic member 402.

[0092] A second motion conversion mechanism is disposed between the second slider 508 and the unlock button 510, converting the sliding of the unlock button 510 into the sliding of the second slider 508. In this embodiment, the second motion conversion mechanism includes a first driving inclined surface 5081 disposed on the second slider 508 and a driving end located at the bottom of the unlock button 510. The first driving inclined surface 5081 is an inclined surface that slopes between the sliding directions of the second slider 508 and the unlock button 510, and the driving end of the unlock button 510 is in abutting contact with the first driving inclined surface 5081. During the movement of the unlock button 510, the motion conversion is completed through the cooperation between the driving end and the first driving inclined surface 5081. Obviously, in order to reduce the friction between the driving end and the first driving inclined surface 5081, the driving end can be a smooth curved surface structure or an inclined surface structure corresponding to the first driving inclined surface 5081. In addition, the first driving inclined surface and the driving end can be replaced by mutually cooperating curved surface structures.

[0093] The working principle of the first unlocking component 5 is as follows: Please refer to... Figure 14a Normally, the limiting groove 110 and the limiting protrusion 5031 are misaligned, and if you try to press the unlock button 510 down, it will not move. Please refer to... Figure 14b After the user rotates the lock cylinder 503 with the key 506 and aligns the limiting groove 110 and the limiting protrusion 5031, they press the unlock button 510. The lock cylinder 503 and the unlock button 510 move downwards synchronously. The driving end of the unlock button 510 drives the second slider 508 to slide towards the side closer to the latch hook 401 through the first driving inclined surface 5081. During the sliding process, it contacts the third protrusion 4014 of the latch hook 401 and can push the latch hook 401 to move to the fourth position against the force of the first elastic element 402, thus completing the unlocking. After unlocking, the unlock button 510 is released, and the lock cylinder compression spring 509 drives the limiting protrusion 503 to disengage from the limiting groove 110.

[0094] In the above embodiments, the lock cylinder 503 is used as the unlocking component, or the lock cylinder 503 and the unlocking button 510 are used together as the unlocking component. Obviously, the unlocking component may also include only the unlocking button 510 without the lock cylinder. Such a design can unlock the handle 3 without rotating the key, which is more convenient and faster.

[0095] As an optional implementation, the unlocking device in the panel lock may further include a second unlocking component 8. Figure 15 This is a schematic diagram of the structure of the second unlocking component provided in an embodiment of this application. Figure 16 This is a structural diagram of the shell corresponding to the second unlocking component portion provided in an embodiment of this application. Figure 17 A schematic diagram illustrating the working principle of the second unlocking component provided in this application embodiment, as shown below. Figures 15 to 17As shown, the second unlocking component 8 includes an unlocking camshaft 801 and a first sealing ring 802. The unlocking camshaft 8 is rotatably mounted on the housing 1 around a third axis, that is, it is set parallel to the rotation direction of the locking tongue hook 401.

[0096] The unlocking camshaft 8 is a shaft-shaped structure extending along the cam axis 8011, including a cam action part 8012, a sealing mounting groove 8014, and a first drive joint 8013 arranged along the cam axis 8011. During installation, the cam action part 8012 is positioned so that it can act on the second protrusion 4016 in the locking tongue hook 401 during rotation. Through the action with the second protrusion 4016, the locking tongue hook 401 is driven to rotate, so that the locking tongue hook 401 disengages from the locking tongue groove 3 of the handle 3, thereby unlocking the handle 3.

[0097] The first drive connector 8013 protrudes relative to the housing 1, and a first sealing ring 802 is installed in the sealing mounting groove 8014 to seal the connection position between the housing 1 and the unlocking camshaft 8, thereby ensuring the sealing performance of the panel lock. The first drive connector 8013 includes an external interface for connecting an external module.

[0098] Figure 18 A schematic diagram of the interaction between the external module and the panel lock is shown. By connecting the external module 9 to the first drive connector 8013, the external module 9 can drive the unlocking camshaft 8 to rotate. This, in turn, through the interaction of the cam action part 8012 and the second protrusion 4016, drives the latch hook 401 to rotate in the opposite direction, thereby disengaging the latch hook 401 from the latch groove 3 of the handle 3 and unlocking the handle 3. It can be seen that the panel lock provided in this embodiment has an external interface for installing the external module 9, enabling remote control or electronic modification of the panel lock.

[0099] The back of the housing 1 is provided with a mounting post 103 for inserting an external module 9. The external interface of the first drive connector 8013 is a mating hole set at the end of the unlocking camshaft 8. The edge of the mating hole is also provided with a first alignment mark 8015. The housing 1 is provided with a second alignment mark 105 corresponding to the first alignment mark 8015. The calibration of the two is completed by the first alignment mark 8015 and the second alignment mark 105.

[0100] The panel lock provided in this application embodiment has an external interface for an external module 9, which allows the panel lock to unlock the handle 3 by connecting to an external device. The external module 9 only needs to be assembled with the mounting post 103 to drive the unlocking camshaft 8 to rotate, thereby increasing the expandability of the panel lock.

[0101] In addition, by setting the first sealing ring 802, the sealing performance of the panel lock is ensured while retaining the external interface.

[0102] Furthermore, a position sensor can be installed on the unlocking camshaft 8 to provide feedback on the rotation angle of the unlocking camshaft 8 to the external module 9. After receiving the rotation angle information of the unlocking camshaft 8, the external module 9 can adjust the state of the unlocking camshaft 8 according to the real-time angle to prevent the unlocking camshaft 8 from rotating too much or too little, which would affect the opening or closing of the lock.

[0103] It should be noted that the first unlocking component 5 and the second unlocking component 8 can work independently. Therefore, in different embodiments of the panel lock, only the first unlocking component 5 or the second unlocking component 8 may be included, or both may be included.

[0104] Please refer to Figures 19 to 21 In this embodiment, the housing 1 includes a rear shell and a rear cover 106. The rear shell has an opening facing the rear side, and the rear cover 106 is fastened to the opening of the rear shell to seal the internal structure. An elliptical first sealing surface 1062 is provided around the opening of the rear shell, and a second sealing surface 1061 corresponding to the first sealing surface 1061 is provided on the rear cover 106. A sealing effect is achieved by a second sealing ring 107 disposed between the first sealing surface 1062 and the second sealing surface 1061, thereby improving the sealing performance.

[0105] The panel lock provided in this application embodiment also includes a pop-out device, which is disposed between the handle 3 and the housing 1, and is used to pop out the handle 3 to an intermediate position between the first position and the second position after the handle 3 is unlocked.

[0106] The ejection device includes a first ejection mechanism 6, which includes a third elastic element 601, a mounting base 602, and a spring cap 603. The mounting base 602 is located inside the side of the handle 3 facing the housing 1. One end of the third elastic element 601 is installed inside the mounting base 602, and the other end is fitted with a spring cap 603.

[0107] In this embodiment, the first pop-out mechanism 6 can pop out the handle 3 at a preset angle when the latch hook 401 disengages from the latch groove 301 of the handle 3 and the user needs to pull the handle 3 to the second position. It is evident that this device allows the handle 3 to pop out at a preset angle before the user grips it, providing sufficient space for the user to insert their fingers, especially when the user is wearing thick gloves, making it easier to grasp the handle 3 and increasing the operability of the panel lock. Furthermore, due to the pop-out mechanism, the first groove does not need to be made too deep, improving the aesthetics of the panel lock.

[0108] In this embodiment, the panel lock has three usage states. When the lock needs to be locked, the first locking component 2 locks the lock to the door, and the second locking component 4 locks the handle 3 in the first groove 101 and the second groove 104 on the front of the housing 1 to prevent the handle 3 from shaking due to external unstable factors. This is the locked state. When the lock needs to be opened, the second locking component 4 unlocks the handle 3. At this time, the first pop-out mechanism 6 pops the handle 3 out at a preset angle for the user to grasp. This is the grasping state. When the user pulls up the handle 3 and rotates the handle 3, it drives the first rotating shaft 201 to rotate. The first rotating shaft 201 drives the first locking tongue 202 of the first locking component 2 to rotate, thereby opening the lock and unlocking. This is the unlocked state.

[0109] As an optional embodiment, refer to Figure 1 The first pop-out mechanism 6 in the aforementioned embodiment also includes a limiting screw 604, and the second groove 104 of the housing 1 is provided with an action boss 102 at the position corresponding to the first pop-out mechanism 6.

[0110] A limiting screw 604 is mounted next to the side wall of the mounting base 602, parallel to the side wall of the mounting base 602. The head of the limiting screw 604 protrudes from the side wall of the mounting base 602 to limit the range of movement of the spring cap 603 on the mounting base 602. The limiting screw 604 adjusts the pop-out angle to a desired value by limiting the maximum movement of the spring cap 603; for example, the pop-out angle can be adjusted to any value between 0 and 10 degrees.

[0111] The functional boss 102 is used to cooperate with the first pop-out mechanism 6 to pop the handle 3 up to a preset angle. The preset angle is usually around 10 degrees, so that the handle 3 will not pop out too high and take up too much space, nor will it pop out too low and be difficult to grasp.

[0112] The ejection device may also include a second ejection mechanism. Figure 22 This is a schematic diagram of the structure of the second ejection mechanism provided in an embodiment of this application. Figure 23 for Figure 22 Schematic diagram of the middle spring bracket. Figure 24 For the working principle diagram of the second ejection mechanism, please refer to... Figures 22 to 24 The second ejection mechanism 7 is located on the handle 3 near the first rotating shaft 201, and includes a spring bracket 702 and an ejection torsion spring 701. The spring bracket 702 is rotatably mounted on the handle 3 about a second axis, that is, the rotation axis of the spring bracket 702 relative to the handle 3 is parallel to the rotation axis of the handle 3 relative to the first rotating shaft 201. One end of the ejection torsion spring 701 presses against the handle 3, and the other end is connected to the spring bracket 702.

[0113] The handle 3 is provided with a second shaft hole 7031 near the first shaft hole 3031. A bracket shaft 703 parallel to the handle shaft 303 is provided in the second shaft hole 7031. The spring bracket 702 is provided with a bracket shaft hole 7023 and can be rotatably installed on the handle 3 through the bracket shaft 703 passing through the bracket shaft hole 7023 and the second shaft hole 7031.

[0114] The spring bracket 702 includes a first limiting surface 7021 and a second limiting surface 7022 surrounding the bracket shaft hole 7023. During movement, the spring bracket 702 rotates around the shaft under the action of the pop-out torsion spring 701 and presses against the blocking side 3041 of the handle 3 through the first limiting surface 7021. As the handle 3 approaches the first rotating shaft 201, the first rotating shaft 201 presses against the first rotating shaft side 2011 of the spring bracket 702 and the second limiting surface 7022, driving the spring bracket 702 to rotate around the shaft, causing the first limiting surface 7021 to move away from the blocking side 3041.

[0115] The working principle of the second ejection mechanism 7 is as follows: after the handle 3 in the first position is released, the first rotating shaft side 2011 interacts with the second limiting surface 7022, and ejects at a certain angle under the action of the ejection torsion spring 701 until the first limiting surface 7021 contacts the blocking side 3041.

[0116] The second ejection mechanism 7 can be used in conjunction with the first ejection mechanism 6, or it can be used independently. In addition, by adjusting the included angle between the first limiting surface 7021 and the second limiting surface 7022, the ejection angle of the handle 3 under the action of the second ejection mechanism 7 can be adjusted. For example, it can be adjusted to any ejection angle between 0 and 90 degrees.

[0117] As an optional embodiment, refer to Figure 1 The panel lock in the aforementioned embodiment also includes an adjusting spring 205 and a fixing ring 2032 disposed on the first rotating shaft 201. The first rotating shaft 201 is slidably disposed on the housing 1 along the first axis. The adjusting spring 205 is sleeved on the first rotating shaft 201, acts between the housing 1 and the fixing ring 2032, and drives the first rotating shaft 201 to slide toward the back of the housing 1 through the fixing ring 2023.

[0118] Please refer to Figure 22 The end of the handle 3 connected to the first rotating shaft 201 includes a first shaft hole 3031 and a third limiting surface 306 and a fourth limiting surface 307 arranged around the first shaft hole 3031. The distance between the third limiting surface 306 and the first shaft hole 3031 is less than the distance between the fourth limiting surface 307 and the first shaft hole 3031. The fourth limiting surface 307 is in contact with the housing 1 when the handle 3 is in the first position, and the third limiting surface 306 is in contact with the housing 1 when the handle 3 is in the second position.

[0119] As an optional embodiment, a fixed friction pad can be inserted between the housing 1 and the handle 3 to reduce the friction between them.

[0120] Since the first pivot 201 and the handle 3 are rotatably connected via the handle pivot 303, when the adjusting spring 205 pushes the fixing ring 2032 downward, the force is transmitted to the handle 3 through the first pivot 201. Therefore, the handle 3 will press against the housing 1 at the position of the handle pivot 303. When the handle 3 moves from the first position to the second position, the contact surface between the handle 3 and the housing 1 changes from the fourth limiting surface 307 to the third limiting surface 306. The distance between the third limiting surface 306 and the first shaft hole 3031 is less than the distance between the fourth limiting surface 307 and the first shaft hole 3031. The size difference is set to, for example, 4mm. This causes the first pivot 201 and the first latch 202 to move a small distance, such as 4mm, toward the back of the housing 1 under the drive of the adjusting spring 205. Moving a small distance allows the first latch 202 to leave the surface of the locking position, reducing the friction when the first latch 202 rotates, making the panel lock easier to unlock.

[0121] As an optional embodiment, refer to Figure 1 and Figure 25 The panel lock in the aforementioned embodiment also includes a first pivot sleeve 206, which is installed at the hinge of the first pivot 201 and the handle 3. It is usually a plastic cover for decorative purposes, which surrounds the rotational position of the first pivot 201 and the handle 3 to prevent dust and debris from entering. In addition, the sliding range of the first pivot 201 and the first locking tongue 202 under the drive of the adjusting spring 205 can be adjusted.

[0122] As an optional embodiment, please refer to Figure 24 The end of the handle 3 connected to the first rotating shaft 201 is provided with a fifth limiting surface 305 parallel to the first shaft hole 3031. The first rotating shaft 201 includes a third rotating shaft 303 side opposite to the first rotating shaft side 2011. The third rotating shaft 303 side is provided with a rotation limiting groove 2012. After the handle 3 is rotated to the first position, the fifth limiting surface 305 enters the rotation limiting groove 2012. The rotation limiting groove 2012 and the fifth limiting surface 305 cooperate to prevent the handle 3 from continuing to rotate.

[0123] As an optional embodiment, the outer surface of the handle 3 is below the highest point of the edge of the first groove 101. This design allows the handle 3 to be lower than the outer surface of the housing 1 when locked, preventing it from occupying too much external space and avoiding unnecessary scratches.
