Detailed Description

As shown in fig. 1 to 8, a locking device 100 according to an embodiment of the present application includes a base 110, an actuator 120 rotatably coupled to the base 110, a first follower 140 displaceably coupled to the base 110, and a second follower 180 displaceably coupled to the base 110.

Actuator 120 is rotatably connected to base 110 via a shaft 121, and actuator 120 is rotatable between a first position 120a and a second position 120b relative to base 110. The rotation axis 121 of the actuator 120 is perpendicular to the main plane 111 of the base 110. The actuator 120 has a first actuator portion 122 and a second actuator portion 128.

The first follower 140 is a cylindrical locking pin with a locking pin long axis 141 parallel to the major plane 111 of the base 110. The first follower 140 is disposed through the pin holes 114 of the inner and outer brackets 114a and 114c of the base 110, and is capable of translating relative to the base 110 in a first axial direction between an unlocked position 140a and a locked position 140b, i.e., a direction parallel to the long axes 141 of the locking pins. A flange 145 is formed between the first controlled end 142 and the first actuating end 148 of the first follower 140. A first resilient member 151, such as a coil spring, is disposed around the stem of the first follower 140 and between the outer leg 114c and the flange 145. The first elastic member 151 is in a prestressed elastic deformation state to apply an elastic force to the first follower 140, so that the first follower 140 has a tendency to be displaced in a direction from the outer stay 114c toward the inner stay 114 a.

The first actuating portion 122 of the actuating member 120 includes a first initial engaging portion 122a formed on the outer side surface of the actuating member 120, a first terminal engaging portion 122c, and a first pushing surface 122b connected between the first initial engaging portion 122a and the first terminal engaging portion 122 c. The first pressing surface 122b is continuous, and has a curved surface or a flat surface profile that monotonically increases from the distance of the first start engaging portion 122a from the rotation axis 141 to the distance of the first end engaging portion 122c from the rotation axis 141.

The longitudinal axis 141 of the lock pin of the first follower 140 is spaced from and perpendicular to the rotating shaft 121 of the actuator 120, that is, the longitudinal axis 141 of the lock pin of the first follower 140 and the rotating shaft 121 of the actuator 120 are in a relative position relationship of mutually perpendicular out-of-plane straight lines. With actuator 120 in first position 120a, actuator 120 is out of contact with first follower 140. Under the elastic force of the first elastic member 151, the first actuating end 148 of the first follower 140 is located inside the outer fulcrum 114c, i.e., when the actuating member 120 is in the first position 120a, the first follower 140 is in the unlocked position 140a.

During the rotation of the actuator 120 relative to the base 110 from the first position 120a to the second position 120b, the first start engaging portion 122a first abuts against the first controlled end 142 of the first follower 140. Further rotation of the actuator 120 in the direction of the second position 120b causes the first pushing surface 122b to maintain an abutting state with the first controlled end 142 of the first follower 140 and slide relatively, while overcoming the elastic force of the first elastic member 151 and causing the first elastic member 151 to be compressed, such that the first follower 140 translates along the longitudinal axis 141 of the latch as the actuator 120 further rotates in the direction of the second position 120 b. When the first end point engaging portion 122c abuts the first controlled end 142 of the first follower 140, the translation of the first follower 140 reaches the end point, and the first actuating end 148 of the first follower 140 is pushed out of the pin hole 114 on the outer support plate 114c by the actuator 120, i.e., when the actuator 120 is at the second position 120b, the first follower 140 is at the locking position 140b.

Rotation of the actuating member 120 relative to the base 110 from the second position 120b to the first position 120a slides the abutment of the first pushing surface 122b and the first controlled end 142 of the first follower 140 from the first terminal engagement portion 122c toward the first initial engagement portion 122a, so that the elastic force of the first elastic member 151 is released. Under the elastic force of the first elastic member 151, the first driven member 140 follows the actuating member 120 to translate toward the first position 120 a. When the first controlled end 142 of the first follower 140 reaches the first initial joint 122a, the translation of the first follower 140 returns to the initial point, and the first actuating end 148 of the first follower 140 withdraws into the pin hole 114 on the outer fulcrum plate 114c, i.e., when the actuator 120 is in the first position 120a, the first follower 140 is in the unlocked position 140a.

In the present embodiment, in the locking position 140b, the first actuating end 148 of the first follower 140 in the shape of a cylindrical lock pin is inserted into the locking hole 68 on the outer member 60, thereby locking the outer member 60 to the base plate 110. In the unlocked position 140a, the first actuating end 148 is disengaged from the locking hole 68 on the outer member 60, thereby unlocking the outer member 60 from the base plate 110.

The second follower 180 is an elongated link having a longitudinal axis 181 perpendicular to the major plane 111 of the base 110. The second follower 180 extends through the slot 118 of the base 110 and is translatable relative to the base 110 in a second axial direction, i.e., parallel to the longitudinal axis 181 of the linkage, between an unlocked position 180a and a locked position 180 b. Both ends of the second follower 180 are biased in a direction perpendicular to the longitudinal axis 181 of the linkage rod from the middle portion 185 toward the actuator 120 to form a second controlled end 182 and a second actuating end 188. The intermediate support 115 is fixedly connected to the base 110. The second controlled end 182 is located between the main plane 111 and the middle support frame 115. A second elastic member 152, such as a coil spring, is disposed between the second controlled end 182 and the middle support frame 115. The second elastic member 152 is in a pre-stressed elastic deformation state to apply an elastic force to the second follower 180 such that the second follower 180 has a tendency to be displaced toward the main plane 111 of the base 110.

The second actuating portion 128 of the actuating member 120 includes a second start engagement portion 128a, a second end engagement portion 128c, and a second pushing surface 128b connected between the second start engagement portion 128a and the second end engagement portion 128c, which are circumferentially arranged along the circumference of the actuating member 120. The distance between the second initial engaging portion 128a and the bottom surface 1209 of the actuator 120 along the direction parallel to the rotating shaft 121 is defined as an initial pressing height H21. The distance between the second terminal engagement portion 128c and the bottom surface 1209 of the actuator 120 is defined as a second terminal pressing height H22. H22 is greater than H21. The second pressing surface 128b has a continuous surface profile monotonically increasing from the start pressing height H21 to the end pressing height H22.

The longitudinal axis 181 of the connecting rod of the second follower 180 is parallel to and spaced apart from the rotating shaft 121 of the actuator 120. The second pushing surface 128b of the actuating member 120 is located between the main plane 111 of the base 110 and the second controlled end 182 of the second follower 180, and the normal direction 128n of the second pushing surface 128b is included at an angle smaller than 90 degrees with the normal direction 111n of the main plane 111, and the second pushing surface 128b is aligned and overlapped along a direction parallel to the rotating shaft 121.

The actuating member 120 is out of contact from the second follower 180 in the first position 120 a. Under the elastic force of the second elastic member 152, the second actuating end 188 of the second follower 180 is located close to the main plane 111 of the base, i.e. when the actuating member 120 is at the first position 120a, the second follower 180 is located at the unlocking position 180a.

During rotation of actuating member 120 relative to base 110 from first position 120a to second position 120b, second initial engagement portion 128a first abuts second controlled end 182 of second follower 180. Further rotation of the actuator 120 in the direction of the second position 120b causes the second pushing surface 182b to maintain an abutting state with the second controlled end 182 of the second follower 80 and slide relatively, while overcoming the elastic force of the second elastic member 152 and causing the second elastic member 152 to be compressed, so that the second follower 180 translates along the longitudinal axis 181 of the connecting rod in a direction away from the main plane 111 of the base along further rotation of the actuator 120 in the direction of the second position 120 b. When the second terminal engagement portion 182c abuts the second controlled end 182 of the second follower 180, the translation of the second follower 180 reaches the terminal point, and the second actuating end 188 of the second follower 180 is located away from the main base plane 111, that is, when the actuating member 120 is in the second position 120b, the second follower 180 is located in the locking position 180a.

Rotation of the actuating member 120 relative to the base 110 from the second position 120b to the first position 120a slides the abutment of the second pushing surface 182b and the second controlled end 182 of the second follower 180 from the second terminal engagement portion 182c to the second initial engagement portion 128a, so that the elastic force of the second elastic member 152 is released, and the second follower 180 translates toward the direction close to the main plane 111 of the base under the elastic force of the second elastic member 152. When the second controlled end 182 of the second follower 180 abuts the second initial engagement portion 128a, the translation of the second follower 180 returns to the initial point, and the second actuating end 188 of the second follower 180 is in a position close to the base main plane 111, i.e., when the actuator 120 is in the first position 120a, the second follower 180 is in the unlocked position 180a.

In the present embodiment, the second actuating end 188 is formed with a locking hole 188h. In the lock position, the lock hole 188h engages with the lock pin 78 on the external part 70, thereby locking the external part to the substrate 110. In the unlocked position, the locking pin 78 on the outer member 70 is disengaged from the locking hole 188h of the second actuator 188, thereby unlocking the outer member from the base plate 110.

As shown in fig. 9 to 15, a locking device 200 according to another embodiment of the present application includes a base 210, an actuating member 220 rotatably connected to the base 210, a first follower 240 displaceably coupled to the base 210, and a second follower 280 displaceably coupled to the base 210.

The actuator 220 is rotatably connected to the base 210 through a rotating shaft 221, and the actuator 220 can rotate between a first position 220a and a second position 220b relative to the base 210. The rotational shaft 221 is perpendicular to the main plane 211 of the base 210. The actuator 220 has a first actuator portion 222 and a second actuator portion 228 formed thereon.

The first follower 240 is a cylindrical locking pin with a locking pin long axis 241 parallel to the major plane 211 of the base 210. The first follower 240 is disposed through the pin holes 214 of the inner and outer plates 214a and 214c of the base 210 and is translatable relative to the base 210 between a locked position 240b and an unlocked position 240a along a first axis, i.e., parallel to the long axis 241 of the locking pin. A flange 245 is formed between the first controlled end 242 and the first actuating end 248 of the first follower 240. A first resilient member 251, such as a coil spring, is disposed around the shaft of the first follower 240 and between the inner plate 214a and the flange 245. The first elastic member 251 is in a prestressed elastically deformed state to apply an elastic force to the first follower 240, so that the first follower 240 has a tendency to be displaced from the inner leg 214a in a direction toward the outer leg 214 c.

The locking device 200 includes a wire 230 connected between a first actuator 222 and a first follower 240. Rotation of the actuating member 220 from the second position 220b to the first position 220a pulls the first follower 240 through the wire 230 while overcoming the spring force of the second resilient member 230 to withdraw the first actuating end 240c of the first follower 240 into the pin hole 214 in the outer leg plate 214 c. That is, when the actuating member 220 is in the first position 220a, the first follower 240 is in the unlocked position 248.

Rotation of the actuator 220 from the first position 220a to the second position 220b releases the wire 230. Under the elastic force of the first elastic member 251, the first actuating end 248 of the first follower 240 extends from the pin hole 214 of the outer plate 214c away from the inner plate 214 a. Thus, rotation of the actuator 220 from the first position 220a to the second position 220b allows the first follower 240 to move from the unlocked position 240a to the locked position 240b. That is, when the actuating member 220 is in the second position 220b, the first follower 240 is in the locked position 240b.

In this embodiment, in the locking position 240b, the first actuating end 248 of the first follower 240 in the shape of a cylindrical locking pin is inserted into the locking hole 68 on the outer member 60, thereby locking the outer member 60 to the base plate 210. In the unlocked position 240a, the first actuator end 248 is disengaged from the latch hole 68 on the outer member 60, thereby unlocking the outer member 60 from the base plate 210.

The second follower 280 is an elongated link having a longitudinal axis 281 perpendicular to the major plane 211 of the base 210. The second follower 280 extends through the slot 218 of the base 210 and is translatable relative to the base 210 in a second axial direction, i.e., parallel to the longitudinal axis 281 of the linkage, between an unlocked position 280a and a locked position 280b. Both ends of the second follower 280 are biased in a direction perpendicular to the connecting rod longitudinal axis 281 from the middle portion 285 toward the actuating member 220 to form a second controlled end 282 and a second actuating end 288. The middle support frame 215 is fixedly connected to the base 210. The second controlled end 282 is located between the main plane 211 and the intermediate support shelf 215. A second elastic member 252, such as a coil spring, is disposed between the second controlled end 282 and the base 210. The second elastic member 252 is in a prestressed elastic deformation state to apply an elastic force to the second follower 280 such that the second follower 280 has a tendency to be displaced in a direction away from the main plane 111 of the base 110.

The second actuating portion 228 of the actuating member 220 includes a second start engagement portion 228a, a second end engagement portion 228c, and a second pushing surface 228b connected between the second start engagement portion 228a and the second end engagement portion 228c, which are circumferentially arranged along the circumference of the actuating member 220. The distance between the second initial engaging portion 228a and the top surface 2201 of the actuator 220 along the direction parallel to the rotating shaft 121 is defined as an initial pressing height H41. The distance between the second terminal engagement portion 228c and the top surface 2209 of the actuator 220 defines a second terminal pressing height H42. H41 is greater than H42. The second pressing surface 228b has a continuous curved surface profile that monotonically decreases from the start pressing height H41 to the end pressing height H42.

The longitudinal axis 281 of the connecting rod of the second driven member 280 is parallel to and spaced apart from the rotation axis 221 of the actuating member 220. The second controlled end 280a of the second follower 280 is located between the second pressing surface 228b and the main plane 211 of the base 210, the normal direction 228n of the second pressing surface 228b is at an angle greater than 90 degrees with respect to the normal direction 211n of the main plane 211, and the second pressing surface 228b is aligned in a direction parallel to the rotation axis 221 and overlaps.

When the actuator 220 is in the first position 220a, the second initial engaging portion 228a abuts against an upper edge of the second controlled end 280a. Rotation of the actuating member 220 from the first position 220a toward the second position 220b causes the abutment of the second actuating portion 228 with the upper edge of the second controlled end 280a to slide along the second pushing surface 228b from the second initial engagement portion 228a to the second final engagement portion 228c, and at the same time, releases the elastic force of the second elastic member 252, so that the second follower 280 translates in a direction away from the main base plane 111 under the elastic force of the second elastic member 252. When the actuator 220 rotates to the second position 220b, the second terminal engagement portion 228c abuts the second controlled end 280a, and the second follower 280 moves to the locking position 280b. That is, when the actuating member 220 is in the second position 220b, the second follower 280 is in the locked position 280b.

Rotation of the actuating member 220 relative to the base 210 from the second position 220b to the first position 220a causes the abutment of the second actuating portion 228 with the upper edge of the second controlled end 280a to slide from the second terminal engagement portion 228c along the second pushing surface 228b to the second initial engagement portion 228a, while overcoming the elastic force of the second elastic member 252 and causing the second follower 280 to translate toward the main plane 111 of the base 110. When the actuator 220 rotates to the first position 220a, the second starting point engaging portion 228a abuts the second controlled end 280a, so that the second follower 280 moves to the unlocking position 280a. That is, when the actuating member 220 is in the first position 220a, the second follower 280 is in the unlocked position 280a.

In the present embodiment, the second actuating end 288 is formed with a locking hole 288h. In the locking position, the locking hole 288h engages with the locking pin 78 on the external member 70, thereby locking the external member 70 to the base plate 210. In the unlocked position, the locking hole 288h of the second actuating end 288 disengages from the locking pin 78 on the outer member 70, thereby unlocking the outer member from the base plate 210.

The locking device 100 or 200 according to the foregoing embodiments may be disposed on a computing device, such as a server, for controlling two components or parts on a server chassis, such as controlling the locking and unlocking states of a top cover and a bottom module of the computing device and the chassis.

According to one embodiment, as shown in fig. 16, 17, and 18, a computing device 300 according to the present application includes a chassis 310, a module 320 detachable or openable from the chassis 310, and a cover 380. The locking device 100 or 200 according to the previous embodiment may be mounted to the frame 310 for controlling the locked and unlocked states of the module 320 and the upper cover 380 with respect to the cabinet 310.

Taking the locking device 100 as an example, the base 110 of the locking device 100 is fixedly connected to the frame 310. The module 320 and the cover 380 are detachably mounted to the housing 310. The module 320 is provided with a locking hole 314 that is aligned with the pin hole 114 in the outer plate 114c of the locking device 100. The cover 380 is provided with a locking pin 388 that is aligned with the locking hole 188h of the second actuating end 188 of the locking device 100.

When the actuator 120 is in the first position, the first follower 140 is in the unlocked position, and the first follower 140 is disengaged from the locking hole 314 of the module 320, such that the module 320 can be removed from the housing 310. Meanwhile, when the actuator 120 is in the first position, the second follower 180 is in the unlocked position, and the locking hole 180h of the second actuating end 188 is disengaged from the locking pin 388 of the upper cover 380, such that the housing 380 may be removed from the housing 310.

When the actuator 120 is in the second position, the first follower 140 is in the locked position, and the first actuating end 148 of the first follower 140 extends out of the pin hole 114 of the outer plate 114c and is inserted into the lock hole 314 of the module 320, so as to lock the insertion module 320 to the housing 310. Meanwhile, when the actuator 120 is in the second position, the second follower 180 is in the locked position, and the locking hole 188h of the second actuating end 188 receives the locking pin 388 of the upper cover 380 therein, so that the rack 380 is locked to the rack 310. As described above, the computing device 300 according to the present embodiment can simultaneously implement the locking and unlocking operations of the two components through the single actuator 120.

The above description is only illustrative of the present application. Various alternatives and modifications can be devised by those skilled in the art without departing from the disclosure. Accordingly, the present application is intended to embrace all such alternatives, modifications and variances which fall within the scope of the appended claims.
