Technical Field

[0001] This application relates to a locking device. Background Technology

[0002] A locking device is a common device used to secure a first object to a second object or to unlock a second object.

[0003] Electronic devices such as servers often require locking mechanisms to lock or unlock circuit boards. In such environments, locking mechanisms must be simple in structure, easy to operate, and small in size. Furthermore, they must be stable, reliable, and not easily disassembled. Additionally, they must have a clean appearance to prevent them from scratching other objects.

[0004] Therefore, the design of locking devices presents new challenges. Utility Model Content

[0015] In one embodiment, the top surface is provided with a shoulder that abuts against the outer frame, such that the movement of the first locking member toward its unlocked position causes the second locking member to move toward its unlocked position, and the movement of the second locking member toward its locked position causes the first locking member to move toward its locked position.

[0016] In one embodiment, the locking device includes a locking spring, and the interior of the housing has a first abutment portion facing the extension of the second locking member. The locking spring is disposed between the extension and the first abutment portion to bias the second locking member toward its locked position.

[0017] A locking device according to this application includes: a housing, mounted to a third object; a mounting member, configured to be inserted into the third object to mount the housing to the third object; and a sliding member, slidably disposed in the housing to adjust the depth of the mounting member inserted into the third object.

[0018] In one embodiment, the mounting member includes: a driven portion disposed in the housing and slidable by the slider along the direction of insertion into the third object; a column portion rotatably connected to the driven portion and sliding together with the driven portion along the direction of insertion into the third object; and wings disposed on radially opposite sides of the column portion, the column portion being alignable with a hole in the third object for insertion into the third object and being angled with the hole to mount the locking device to the third object.

[0019] In one embodiment, the slider includes: a slider inserted into a fourth groove in the side wall of the housing to guide the slider to slide relative to the housing; and a drive portion engaged with a driven portion of the mounting member such that the slider sliding relative to the housing causes the mounting member to extend out of or retract into the housing.

[0020] In one embodiment, the slider further includes a limiting groove extending along the sliding direction of the slider; the housing has a bottom opening with a first baffle and a second baffle, the slider is accommodated in the bottom opening, and the first baffle and the second baffle are inserted into the limiting groove to limit the stroke of the slider.

[0021] In one embodiment, the driven portion of the mounting member is disposed between the first baffle and the second baffle to guide the sliding of the mounting member relative to the housing.

[0022] In one embodiment, the locking device includes a sliding spring disposed between the housing and the sliding member to bias the sliding member in a direction of disengagement from the housing. The sliding of the sliding member in the direction of disengagement from the housing causes the mounting member to move in a direction of retraction into the housing, such that the mounting member abuts against the third object.

[0023] In one embodiment, the locking device further includes a mounting spring disposed between the housing and the mounting member to bias the mounting member in a direction away from the housing, wherein the biasing force of the mounting spring is insufficient to resist the biasing force of the sliding spring.

[0096] While this invention has been illustrated and described with reference to specific embodiments, it should not be limited to the details shown. Rather, various modifications to these details may be made within the scope of equivalents of the claims without departing from the invention.

[0097] The descriptions of directions such as "front", "back", "up" and "down" in this article are for ease of understanding only. This utility model is not limited to these directions, but can be adjusted according to the actual situation.

[0098] Reference Figures 1A to 2 Overall description of the locking device 100 according to this application, which is used to mount a first object 200, such as a memory card, and a second object 300 to a third object 400, such as a motherboard (see...). Figure 13A and Figure 13BThe locking device 100 includes: a first locking member 110, a second locking member 120, a trigger 130, a mounting member 140, a sliding member 150, a housing 160, a locking member spring 181, a trigger spring 182, a mounting member spring 183, and a sliding member spring 184.

[0099] The housing 160 is mounted to the third object 400 and at least partially accommodates other components of the locking device 100. The first locking member 110 is configured to move between a locked position and an unlocked position to mount the first object 200 to the third object 400. The second locking member 120 is configured to move between a locked position and an unlocked position to mount the second object 300 to the third object 400. The first locking member 110 and the second locking member 120 are stacked, i.e., the first locking member 110 is located below (i.e., closer to the third object 400), and the second locking member 120 is located above (i.e., away from the third object 400). During unlocking, the second locking member 120 can be unlocked first, followed by the first locking member 110, or both can be unlocked simultaneously, i.e., the second locking member 120 is moved to the unlocked position by the first locking member 110. When locked, the locking spring 181 simultaneously biases the first locking member 110 and the second locking member 120 to the locked position. The structure and operation of the first locking member 110 and the second locking member 120 will be described in detail later.

[0100] Trigger 130 is configured to move between a holding position and a release position. In the holding position, trigger 130 holds the first locking member 110 in its unlocked position, and the first object 200, attached to the third object 400, causes trigger 130 to move to the release position. Since the first locking member 110 is configured to move the second locking member 120 to the unlocked position, when the first locking member 110 is held in the unlocked position, it can also hold the second locking member 120 in the unlocked position. Therefore, trigger 130 effectively holds both the first locking member 110 and the second locking member 120 in the unlocked position. When trigger 130 releases the first locking member 110, both the first locking member 110 and the second locking member 120 return to the locked position under the action of the locking member spring 181. The structure and operation of trigger 130 will be described in detail later.

[0101] Mounting member 140 is at least partially housed in housing 160 and configured to insert into third object 400 to mount housing 160 to third object 400. Sliding member 150 is slidably disposed in housing 160 to adjust the insertion depth of mounting member 140 into third object 400 to accommodate third object 400 of various thicknesses. Mounting member spring 183 is disposed between housing 160 and mounting member 140 to bias mounting member 140 in a direction of disengagement from housing 160 (i.e., insertion into third object 400), and the biasing force of mounting member spring 183 is insufficient to resist the biasing force of sliding member spring 184. Sliding member spring 184 is disposed between housing 160 and sliding member 150 to bias sliding member 150 in a direction of disengagement from housing 160. Sliding of sliding member 150 in the direction of disengagement from housing 160 causes mounting member 140 to move in a direction of retraction into housing 160, such that mounting member 140 abuts against third object 400.

[0102] Reference Figures 3A to 3D The specific structure of the housing 160 is described. The housing 160 is a generally rectangular box shape and includes a top opening 161, a bottom opening 162, two opposing side walls 163, a tail groove 165, a first abutment portion 166, a second abutment portion 167, a third abutment portion 168, and a cylindrical portion 169.

[0103] The top opening 161 and the bottom opening 162 are vertically opposite each other, and the two side walls 163 are horizontally opposite each other, making the housing 160 an open shape. The two side walls 163 are respectively provided with a first groove 163a, a second groove 163b, a third groove 163c, and a fourth groove 163d, all of which can be formed as longitudinally extending linear grooves. The first groove 163a and the second groove 163b are located at the vertical middle of the side walls, with the first groove 163a located at the front end of the housing 160 (i.e., the end that engages with the first object 200 and the second object 300, or the end where the cylindrical portion 169 is located), and the second groove 163b located at the rear end of the housing 160 (i.e., the end away from the first object 200 and the second object 300). The third groove 163c is located at the upper part of the side wall, and the fourth groove 163d is located at the lower part of the side wall. The tail groove 165 is formed at the upper part of the rear end wall of the housing 160, for example, it is formed to extend downward from the upper end of the rear end wall and has an enlarged dovetail shape at the lower end.

[0104] A cylindrical portion 169 is formed at the front end and bottom of the housing 160, extending vertically and opening upward, and an annular space is formed around the cylindrical portion 169 to accommodate the trigger spring 182.

[0105] The first abutment portion 166, the second abutment portion 167, and the third abutment portion 168 are all formed inside the housing 160. The first abutment portion 166 is located approximately at the center of the housing 160. The first abutment portion 166 is formed as a forward-extending protrusion to abut against the locking spring 181. The second abutment portion 167 is located near the rear end of the housing 160, between the first baffle 162a and the second baffle 162b of the housing 160. The second abutment portion 167 is formed as a vertically extending and downward-opening hole to abut against the mounting spring 183. The third abutment portion 168 is provided near the front end of the housing 160 and is formed as a rearward-extending protrusion to abut against the sliding spring 184.

[0106] Both the first baffle 162a and the second baffle 162b are vertically extending baffles, specifically extending from near the vertical center of the housing 160 to the bottom opening 162 of the housing 160. The first baffle 162a and the second baffle 162b are arranged longitudinally, specifically, the first baffle 162a is located at the rear end of the housing 160, and the second baffle 162b is located near the vertical center of the housing 160.

[0107] Reference Figure 4A and Figure 4B The specific structure of the first locking member 110 is described. The first locking member 110 includes a first joint 111, an outer frame 112, a hook 113, a side rib 114, and a protrusion 115.

[0108] The first engagement portion 111 is located at the front end of the first locking member 110 and is in the form of a vertically extending column. The upper surface of the first engagement portion 111 is opposite to the second engagement portion 121 of the second locking member 120 to lock the second object 300, and the lower surface of the first engagement portion is opposite to the trigger 130 to lock the first object 200 (see [link]). Figure 9D and Figure 9E The front surface of the first joint 111 may be cylindrical to avoid scratching the first object 200 or the second object 300, but is not limited to this shape.

[0109] The outer frame 112 is a rectangular frame extending vertically and horizontally, and its lower edge is connected to both sides of the first joint 111 by two side ribs 114. The outer frame 112 is fitted onto the outside of the housing 160 (see...). Figure 9A This allows the user to move the first locking member 110 directly via the outer frame 112. The outer frame 112 abuts against the second locking member 120 along the longitudinal direction (i.e., the sliding direction of the first locking member 110 and the second locking member 120), so that the first locking member 110 drives the second locking member 120 to move in the unlocking direction, and the second locking member 120 drives the first locking member 110 to move in the locking direction.

[0110] Side rib 114 connects between the first joint 111 and the outer frame 112 and is inserted into the first groove 163a of the side wall 163 of the housing 160 to guide the first locking member 110 to slide along the housing 160. Two hooks 113 extend along the moving direction of the first locking member 110 and are inserted into the second groove 163b of the side wall 163 of the housing 160 to guide the first locking member 110 to slide along the housing 160 and limit the sliding stroke of the first locking member 110.

[0111] The protrusion 115 is formed below the first engagement portion 111 and is recessed rearward relative to the first engagement portion 111, thus forming a stepped structure with the first engagement portion 111. When the first locking member 110 is in the unlocked position, the protrusion 115 is aligned with and received in the recess 133 of the trigger 130, so that the first locking member 110 is held in the unlocked position (see...). Figure 12E In this embodiment, the protrusion 115 is formed as a semi-circle, but is not limited thereto. In other embodiments, the protrusion 115 may be formed as a rectangle, trapezoid, etc.

[0112] Reference Figure 5A and Figure 5B The specific structure of the second locking member 120 is described. The second locking member 120 includes a second engaging portion 121, an extension portion 122, a locking member spring abutment portion 123, a side sliding portion 124, a tail sliding portion 125, an operating portion 126, and a top surface 127.

[0113] The second engagement portion 121 is located at the front end of the second locking member 120, and the second object 300 is held between the first engagement portion 111 and the second engagement portion 121. The second engagement portion 121 is formed as a cone shape with a smaller upper end and a larger lower end. When the second object 300 is installed into the locking device 100, the first object 200 can push against the cone-shaped surface of the second engagement portion 121, so that the second engagement portion 121 overcomes the bias of the locking member spring 181 and temporarily leaves the locked position, thereby easily installing the second object 300 into the locking device 100. The shape of the lower end of the second engagement portion 121 can correspond to the shape of the first engagement portion 111 in order to stably hold the second object 300.

[0114] The extension 122 is inserted into the housing 160 in a direction substantially perpendicular to the direction of movement of the second locking member 120. The extension 122 is opposite to the first abutment portion 166 of the housing 160 so as to abut the locking member springs 181 from both ends (see...). Figure 9E ).

[0115] Two side sliding portions 124 are formed as hooks extending downward from both sides of the top surface 127 and are respectively inserted into the third sliding grooves 163c of the two side walls 163 of the housing 160 to guide the sliding of the second locking member 120 relative to the housing 160 and limit the sliding stroke of the second locking member 120. A tail sliding portion 125 extends downward from the rear end of the top surface 127 and is formed as a dovetail shape with an enlarged lower end, so as to be inserted into the tail groove 165 of the housing 160 to guide the sliding of the second locking member 120 relative to the housing 160. The top surface 127 covers the top opening 161 of the housing 160 to substantially close the top surface 127 of the locking device 100. An operating portion 126 rises from the rear end of the top surface 127 to allow the user to move the second locking member 120.

[0116] The top surface 127 may be provided with a shoulder 127a, which is located at the front edge of the top surface 127 so as to abut against the outer frame 112, such that the movement of the first locking member 110 toward its unlocked position causes the second locking member 120 to move toward its unlocked position, and the movement of the second locking member 120 toward its locked position causes the first locking member 110 to move toward its locked position.

[0117] Reference Figure 6A and Figure 6B The specific structure of the trigger 130 is described. The trigger 130 includes a contact block 131, a rod portion 132, a recess 133, and an annular groove 134.

[0118] The engaging block 131 is located at the upper end of the trigger 130 and is approximately perpendicular to the vertical direction. When the first locking member 110 is in the locked position, the engaging block 131 and the first engaging portion 111 of the first locking member 110 are opposite each other to retain the first object 200 (see [link]). Figure 9D and Figure 9E The joining block 131 may have an arc-shaped leading edge to correspond to the shape of the first joining portion 111.

[0119] The recess 133 is formed to be recessed from the engaging block 131, specifically from the rear end of the engaging block 131 downwards. The shape of the recess 133 corresponds to the protrusion 115 of the first locking member 110, for example, it is formed as a circle, rectangle or trapezoid. The rod portion 132 extends vertically downwards from the lower surface of the engaging block 131, and an annular groove 134 is formed between the outer periphery of the rod portion 132 and the engaging block 131. The rod portion 132 is inserted into the cylinder portion 169 of the housing 160 along the sliding direction of the trigger 130, and the trigger spring 182 is sleeved on the outside of the cylinder portion 169 and received in the annular groove 134 (see...). Figure 9E ).

[0120] Reference Figure 7A and Figure 7BThe specific structure of the mounting component 140 is described. The mounting component 140 includes a column portion 141, a wing portion 142, a driven portion 143, and a mounting component spring abutment portion 144.

[0121] The driven part 143 is located on the upper part of the mounting member 140 and is a frame shape extending laterally. The two ends of the driven part 143 are respectively provided with inclined surfaces 143a extending longitudinally. The column part 141 is located on the lower part of the mounting member 140 and is connected to the driven part 143, and slides together with the driven part 143 in the vertical direction (i.e., the direction in which the third object 400 is inserted).

[0122] Wings 142 are disposed on both radial sides of the post 141 to rotate with the post 141. The third object 400 has a hole 410 whose shape roughly corresponds to the shape of the wing 142. Therefore, when the wing 142 is aligned with the hole 410, the mounting member 140 can pass vertically through the hole 410. When the wing 142 is at an angle to the hole 410, the wing 142 engages with the third object 400, preventing the mounting member 140 from passing through the hole 410, thus installing the locking device 100 onto the third object 400. For example, when installing the locking device 100 onto the third object 400, the user first rotates the locking device 100 about 90 degrees around the vertical axis, that is, from... Figures 13A to 13C Rotate the device 90 degrees to the indicated position so that the wing 142 aligns with the hole 410, allowing the mounting piece 140 to pass through the hole 410. Then, the user inserts the mounting piece 140 through the hole 410 and rotates the lock 100 90 degrees in the opposite direction back to its original position. Figures 13A to 13C The position shown is such that the wing 142 is not aligned with the hole 410, but rather rests against the lower surface of the third object 400, thus preventing the mounting member 140 from passing through the hole 410, so that the locking device 100 is installed onto the third object 400.

[0123] The mounting spring abutment 144 is provided at the top surface 127 of the driven part 143 and is configured as a vertically extending hole. Both ends of the mounting spring 183 abut against the mounting spring abutment 144 and the second abutment 167 of the housing 160, respectively, to bias the mounting part 140 toward a position extending from the housing 160, i.e., the position inserted into the third object 400 (see reference). Figure 9E ).

[0124] Reference Figure 8A and Figure 8B The specific structure of the slider 150 is described. The slider 150 includes a slider 151, a driving part 152, a slider spring abutment part 153, a slider tail part 154, and a limiting groove 155.

[0125] The slider 150 is a generally rectangular block extending longitudinally. Two sliders 151 are formed on both sides of the slider 150 and are respectively inserted into the fourth groove 163d of the housing 160 to guide the slider 150 to slide relative to the housing 160. A drive portion 152 is formed on the upper part of the slider 150 and is shaped as an incline with a higher front end and a lower rear end. The angle of the drive portion 152 corresponds to the inclined surface 143a of the driven portion 143 of the mounting member 140 so as to engage with the driven portion 143.

[0126] A limiting groove 155 is disposed at the bottom of the slider 150 and extends along the sliding direction (i.e., longitudinally) of the slider 150. The lateral dimension of the limiting groove 155 approximately corresponds to the first baffle 162a and the second baffle 162b of the housing 160, and its longitudinal dimension is greater than the distance between the first baffle 162a and the second baffle 162b. Therefore, when the slider 150 is accommodated in the bottom opening 162 of the housing 160, the first baffle 162a and the second baffle 162b are inserted into the limiting groove 155 to limit the stroke of the slider 150 (see...). Figure 9C ).

[0127] Reference Figures 9A to 9E The operation of the locking device 100 according to this application is described. At this time, the first locking member 110 and the second locking member 120 of the locking device 100 are both in the locked position, the sliding member 150 is in the position retracted into the housing 160, and the mounting member 140 is in the position protruding from the housing 160.

[0128] Specifically, both the first locking member 110 and the second locking member 120 are located near the front end of the housing 160. Figure 9D and Figure 9E (Left side of the image). The first engagement portion 111 of the first locking member 110 is aligned with the engagement block 131 of the trigger 130, thus forming a space for clamping the first object 200 between the lower surface of the first engagement portion 111 and the upper surface of the engagement block 131. The second engagement portion 121 of the second locking member 120 is aligned with the first engagement portion 111 of the first locking member 110, thus forming a space for clamping the second object 300 between the lower surface of the second engagement portion 121 and the upper surface of the first engagement portion 111. The locking spring 181 tends to bias the second locking member 120 toward its locked position, so in this state, the second locking member 120 is held in its locked position by the locking spring 181. Since the shoulder of the second locking member 120 abuts against the outer frame 112 of the first locking member 110, the first locking member 110 is held in its locked position by the second locking member 120.

[0129] The protrusion 115 of the first locking member 110 abuts against the engagement block 131 of the trigger 130, but is not aligned with the recess 133 of the trigger 130, thus the trigger 130 is held in a lower position. In this position, the trigger 130 does not impede the sliding of the first locking member 110.

[0130] The slider 150 is in the position where it is retracted to its maximum extent into the housing 160, such that the tail 154 of the slider abuts against the rear end of the housing 160. Figure 9D and Figure 9E (right side of the middle), and the first baffle 162a abuts against the rear end of the limiting groove 155 (see the right ...). Figure 9C The slider spring 184 biases the slider 150 to extend out of the housing 160 (i.e., biases the slider 150 backward), and the user can manually hold the slider tail 154 to keep it in the housing 160.

[0131] The lower portion of the drive unit 152 is aligned with the driven portion 143 of the mounting member 140, so that the mounting member 140 extends downward out of the housing 160 under the bias of the mounting member spring 183. Since the mounting member 140 extends out of the housing 160, the user can easily pass the mounting member 140 through the corresponding hole (not shown) in the third object 400 and rotate the post portion 141 of the mounting member 140 to engage the wing portion 142 of the mounting member 140 with the third object 400.

[0132] from Figures 9A to 9E As shown in the diagram, the user releases the slider tail 154 of the slider 150, causing the locking device 100 to transition to the position indicated. Figures 10A to 10E The state is shown. During this process, the slider 150 extends out of the housing 160 (i.e., moves backward) under the bias of the slider spring 184, so that the higher portion of the drive portion 152 corresponds to the driven portion 143, thereby causing the mounting member 140 to retract into the housing 160 (i.e., move upward). As mentioned above, the bias force of the mounting spring 183 is insufficient to counteract the slider spring 184, so the mounting spring 183 is compressed during this process. The mounting member 140 moves upward until its wing 142 abuts against the lower surface of the third object 400 (not shown), causing both the mounting member 140 and the slider 150 to stop moving. It should be understood that... Figures 10A to 10E The diagram shows the position where the slider 150 extends most of its length out of the housing 160, which is also the position where the mount 140 retracts most of its length into the housing 160. However, depending on the vertical thickness of the third object 400, when the mount 140 is stably engaged with the third object 400, the slider 150 and the mount 140 can stop at... Figures 9A to 9E Position and Figures 10A to 10E At any position between the positions.

[0133] from Figures 10A to 10EAs shown in the diagram, when it is necessary to remove the locking device 100 from the third object 400, the user can grasp the slider tail 154 to compress the slider 150 back into the housing 160. Therefore, the mounting member 140 extends from the housing 160 under the action of the mounting member spring 183, causing the locking device 100 to return to its original position. Figures 9A to 9E The state shown makes it easy to remove from the third object 400.

[0134] from Figures 10A to 10E Starting from the indicated state, the user moves the second locking member 120 backward, causing the locking device 100 to transition to... Figures 11A to 11E The state shown. For example, the user can grasp the operating part 126 of the second locking member 120 and slide it backward, or can use the second object 300 (see...) Figure 13B and Figure 13C The second locking member 120 slides toward the unlocked position by pressing against and pressing down on the tapered upper surface of the second engagement portion 121.

[0135] During this process, the second locking member 120 resists the pressure of the locking member spring 181 and slides to its unlocked position (i.e., moves backward). As mentioned above, the second locking member 120 cannot cause the first locking member 110 to slide toward the unlocked position, so the first locking member 110 remains in its locked position.

[0136] When the second object 300 is installed in place, it occupies the receiving space between the first joint 111 and the second joint 121, and no longer obstructs the second locking member 120 from moving to its locked position. Therefore, the second locking member 120 returns to the locked position under the bias of the locking member spring 181, causing the locking device 100 to return to its locked position. Figures 10A to 10E The state shown.

[0137] from Figures 10A to 10E Starting from the indicated state, the user moves the first locking member 110 backward, causing the locking device 100 to transition to... Figures 12A to 12E The state shown. For example, a user can hold the outer frame 112 of the first locking member 110 and slide it backward.

[0138] During this process, the first locking member 110 drives the second locking member 120 to slide towards their respective unlocked positions against the bias of the locking member spring 181. When the first locking member 110 reaches its unlocked position, the protrusion 115 of the first locking member 110 aligns with the recess 133 of the trigger 130, causing the trigger 130 to move upward under the bias of the trigger spring 182 and retain the protrusion 115 in the recess 133. Therefore, the first locking member 110 is held in the unlocked position by the trigger 130, and the second locking member 120 is held in the unlocked position by the first locking member 110.

[0139] exist Figures 12A to 12E In the indicated state, both the first locking member 110 and the second locking member 120 are in the unlocked position, thus allowing the first object 200 and the second object 300 to engage with or disengage from the locking device 100. Figures 12A to 12E The user begins in the state shown, placing the first object 200 (see...) Figure 13B and Figure 13C The first object 200 is placed on the upper surface of the engagement block 131 of the trigger 130 and is pressed down by the engagement block 131. Therefore, the trigger 130 moves downward and releases the first locking member 110, i.e., it is no longer held in its unlocked position. As mentioned above, the second locking member 120 is held in the unlocked position by the first locking member 110, so when the first locking member 110 is released, the second locking member 120 is released by the first locking member 110. Therefore, the second locking member 120 returns to its locked position under the bias of the locking member spring 181, simultaneously driving the first locking member 110 back to its locked position, and causing the first object 200 to be clamped between the first engagement 111 and the engagement block 131. At this time, the locking device 100 returns to its locked position. Figures 10A to 10E The location shown.

[0140] Reference Figures 13A to 13C The following describes the usage of the locking device 100 according to this application. The locking device 100 is mounted to a third object 400, such as a circuit board, and locks a first object 200 and a second object 300, such as a memory module or a solid-state drive. The first object 200 and the second object 300 are stacked vertically and mounted to the locking member from top to bottom. As described above, the user can hold the outer frame 112 of the first locking member 110 to move the first locking member 110 and the second locking member 120 to the unlocked position, and then mount the first object 200 from top to bottom between the first locking member 110 and the trigger 130. At this time, the first locking member 110 automatically returns to the locked position. The user then mounts the second object 300 between the first locking member 110 and the second locking member 120, and the second locking member 120 automatically locks the second object 300.
