The first contact surface, the arc surface, and the second contact surface are all used to slide with the first protrusion. When a portion of the first protrusion is located in a groove, the first protrusion is connected to the first contact surface.

[0008] In some embodiments of this application, the first protrusion includes a pressing surface that is parallel to a first direction and intersects with a second direction. The pressing surface is used to contact the first contact surface, the arc surface, and the second contact surface.

Terms such as "upper," "lower," "above," "below," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship also changes accordingly.

[0029] Please see Figure 1 and Figure 2 This application provides a locking assembly 100 for locking terminal elements 200 (see reference). Figure 3 Terminal components 200 include, but are not limited to, servers, circuit boards, and other components that need to be detachably fixed to a bracket (not shown).

[0030] The locking assembly 100 may include a fixing mechanism 10, an elastic element 20, a slider 30, and a rotating element 40. The elastic element 20 connects the fixing mechanism 10 and the slider 30, and the rotating element 40 is rotatably mounted on the fixing mechanism 10. When the locking assembly 100 locks the terminal element 200, the locking assembly 100 can automatically lock; when unlocking the locking assembly 100, rotating the rotating element 40 unlocks it; after the terminal element 200 disengages from the locking assembly 100, the locking assembly 100 can automatically return to its initial position. The locking assembly 100 is simple to operate during both locking and unlocking processes, making it easy for users to use.

[0031] The fixing mechanism 10 may include a base 11 and a rear cover 13, which are fixed to each other. In this embodiment, the rear cover 13 is fixed to the base 11 by a first fixing member 15. In other embodiments, the rear cover 13 may also be fixed to the base 11 by other fixing methods. In another embodiment, the rear cover 13 and the base 11 may also be an integral structure.

[0032] The base 11 includes a top plate 111, a first side plate 112, a second side plate 113, a third side plate 114, and a fourth side plate 115. The first side plate 112, the second side plate 113, the third side plate 114, and the fourth side plate 115 are sequentially arranged around the top plate 111 and are all connected to the top plate 111. The first side plate 112 and the third side plate 114 are arranged opposite to each other, and the second side plate 113 and the fourth side plate 115 are arranged opposite to each other. The rear cover 13 is fixed to the third side plate 114.

[0033] The base 11 has a sliding groove 116 and a receiving groove 117. The sliding groove 116 extends along a first direction L1, is formed on a first side plate 112, and passes through a second side plate 113 and a fourth side plate 115. The sliding groove 116 and the receiving groove 117 are interconnected and are arranged along a second direction L2. The receiving groove 117 is formed on a second side plate 113 and a third side plate 114, and a portion of the rear cover 13 is exposed in the receiving groove 117. The terminal element 200 is slidably disposed in the sliding groove 116 along the first direction L1. The second direction L2 intersects the first direction L1. In this embodiment, the second direction L2 and the first direction L1 are perpendicular to each other. In other embodiments, when the base 11 and the rear cover 13 are an integral structure, the receiving groove 117 can be considered to be formed on the second side plate 113.

[0034] The elastic element 20 is housed in the receiving groove 117. One end of the elastic element 20 is connected to the rear cover 13, and the other end is connected to the slider 30. The elastic element 20 can deform along the second direction L2. In this embodiment, the elastic element 20 is a spring.

[0035] The slider 30 is movably disposed in the fixing mechanism 10 along the second direction L2. The slider 30 includes a first blocking part 31 and a first protruding part 33 fixedly connected. One side of the first blocking part 31 is connected to the elastic member 20, and the first blocking part 31 can move along the second direction L2 into the receiving groove 117 and press the elastic member 20; the side of the first blocking part 31 opposite to the elastic member 20 can be received in the slide groove 116. The first protruding part 33 protrudes from the receiving groove 117 along the first direction L1.

[0036] The first blocking portion 31 includes a first inclined surface 312 and a blocking surface 314, which are two opposite surfaces of the first blocking portion 31. The first inclined surface 312 intersects the first direction L1 and the second direction L2, and the blocking surface 314 is the surface of the slider 30 facing away from the first protrusion 33. The blocking surface 314 is parallel to the second direction L2. When the terminal element 200 slides along the slide groove 116, the terminal element 200 first contacts the first inclined surface 312 and gradually abuts against the first blocking portion 31, so that the first blocking portion 31 moves along the second direction L2 and squeezes the elastic member 20. The first inclined surface 312 is provided so that as the terminal element 200 moves along the first direction L1, the slider 30 can move more smoothly along the second direction L2. When the locking assembly 100 is in the locked state, the slider 30 returns to its initial position under the elastic action of the elastic member 20. Part of the first blocking part 31 is located in the slide groove 116, and the blocking surface 314 is located on one side of the terminal element 200 to limit the terminal element 200. In this embodiment, both the first inclined surface 312 and the blocking surface 314 can be planes.

[0037] The first protrusion 33 includes a pressing surface 332 facing the rotating member 40. The pressing surface 332 is parallel to the first direction L1 and intersects the second direction L2. The pressing surface 332 is used to contact the rotating member 40.

[0038] The rotating member 40 is rotatably mounted on the second side plate 113 about a first direction L1. The rotating member 40 may include a fixedly connected body portion 41, a second protrusion 42, a second blocking portion 43, and a handle portion 44. A fixing portion 118 protruding along the first direction L1 is provided on the second side plate 113. The fixing portion 118 is columnar, and the body portion 41 is generally disc-shaped. The body portion 41 is rotatably fitted onto the fixing portion 118. The locking assembly 100 also includes a second fixing member 50, which is fixed to the side of the fixing portion 118 opposite to the body portion 41, for limiting the rotating member 40 to the fixing portion 118. The second protrusion 42, the second blocking portion 43, and the handle portion 44 all extend radially from the circumference of the body portion 41, and are spaced apart. The handle portion 44 facilitates the user to apply force to rotate the rotating member 40. The first protrusion 33 is located within the rotation path of the second protrusion 42, and the second protrusion 42 is used to drive the first protrusion 33 to move along the second direction L2. The end of the slide groove 116 near the second side is located within the rotation path of the second blocking part 43, and the second blocking part 43 is used to reset the terminal element 200 when it exits the slide groove 116.

[0039] Specifically, the second protrusion 42 includes a first contact surface 422, an arc surface 424, and a second contact surface 426 connected in sequence. The first contact surface 422, the arc surface 424, and the second contact surface 426 are all parallel to the first direction L1. The first contact surface 422 and the second contact surface 426 are connected by the arc surface 424. The first contact surface 422 is the surface of the second protrusion 42 near the handle portion 44, and the second contact surface 426 is the surface of the second protrusion 42 away from the handle portion 44. The first contact surface 422, the arc surface 424, and the second contact surface 426 are all used for sliding connection with the pressing surface 332.

[0040] When a force is applied to the handle 44 to rotate the rotating member 40, the second protrusion 42 rotates and abuts against the pressing surface 332, thereby driving the first protrusion 33 to move along the second direction L2. This, in turn, causes the first blocking part 31 to retract from the slide groove 116 into the receiving groove 117 along the second direction L2. Simultaneously, the first blocking part 31 presses against the elastic member 20 along the second direction L2. During the rotation of the rotating member 40, the first contact surface 422, the arc surface 424, and the second contact surface 426 successively abut against the pressing surface 332.

[0041] The second blocking part 43 has a second inclined surface 432 at its end away from the main body part 41. The second inclined surface 432 faces the base 11 and intersects the first direction L1 and the second direction L2. The end of the slide groove 116 is located within the rotation path of the second inclined surface 432, that is, after the second blocking part 43 rotates, the second inclined surface 432 can be exposed in the slide groove 116. In this embodiment, the second inclined surface 432 is an arc surface. When unlocking the latch assembly 100, the terminal element 200 first contacts the second inclined surface 432 and gradually abuts against the second blocking part 43, so that the second blocking part 43 rotates around the first direction L1. The second inclined surface 432 is provided so that as the terminal element 200 moves along the first direction L1, the rotating member 40 can rotate around the first direction L1 more smoothly.

[0042] The base 11 also includes a stop portion 119, which is disposed on the second side and protrudes from the second side along the first direction L1. The stop portion 119 is located within the rotation path of the second blocking portion 43 and the handle portion 44, and the stop portion 119 is used to stop both the second blocking portion 43 and the handle portion 44.

[0043] Please see Figures 3 to 8 The following describes the components and functions of the locking assembly 100 of this application through specific locking and unlocking processes.

[0044] Please see Figure 3 When the locking assembly 100 is not locked to the terminal element 200, the two ends of the elastic member 20 abut against the rear cover 13 and the first blocking part 31 respectively. Part of the first blocking part 31 is located in the slide groove 116. This state is the initial state of the locking assembly 100.

[0045] Please see Figure 4 When the locking assembly 100 is needed to lock the terminal element 200, one side of the terminal element 200 is placed in the slide groove 116. A force F1 is applied to the terminal element 200, pushing it to slide along the first direction L1. During the sliding process, the terminal element 200 first comes into contact with and gradually abuts against the first inclined surface 312 of the first blocking part 31, causing the first blocking part 31 to move along the second direction L2 and compress the elastic member 20, causing the elastic member 20 to deform along the second direction L2.

[0046] Please see Figure 5As the terminal element 200 slides further until the critical point where it separates from the first blocking part 31 (i.e., the preset position of the terminal element 200 in the slide groove 116), the first blocking part 31 loses the force exerted by the terminal element 200 on it. At this point, the slider 30 returns to its initial position under the elastic action of the elastic member 20 and is driven to move along the second direction L2 toward the slide groove 116 until a portion of the first blocking part 31 is located in the slide groove 116. The blocking surface 314 of the first blocking part 31 is located on one side of the terminal element 200 to limit the terminal element 200. At this time, the automatic locking process of the locking assembly 100 on the terminal element 200 is completed. In this process, only a force needs to be applied to the terminal element 200, and no additional force needs to be applied to the locking assembly 100 to perform the locking process, which can prevent the user from forgetting the locking step.

[0047] Please see Figure 6 When unlocking is required, a force F2 is applied to the rotating member 40. During rotation, the second protrusion 42 abuts against the first protrusion 33, driving the first protrusion 33 to move along the second direction L2 and compress the elastic member 20. That is, the first contact surface 422, the arc surface 424, and the second contact surface 426 abut against the pressing surface 332 in sequence. The first blocking part 31 moves synchronously with the movement of the first protrusion 33 and releases its limiting effect on the terminal element 200. At this time, the second inclined surface 432 of the second blocking part 43 is exposed to the groove 116. When the second contact surface 426 abuts against the pressing surface 332, the pressing surface 332 exerts a force F on the second contact surface 426 in the direction of the rotation center of the rotating member 40. The force F can offset at least part of the elastic restoring force of the elastic member 20. After the force F2 is removed, the slider 30 can be kept temporarily stationary in this state to prevent the slider 30 from resetting. This allows the user to free their hands to apply force to the terminal element 200 and the bracket.

[0048] Please see Figure 7 A force F3 is applied to the terminal element 200, causing it to slide out along the groove 116. The terminal element 200 first contacts the second inclined surface 432 and gradually abuts against the second blocking part 43, causing the second blocking part 43 to rotate around the first direction L1. As the second blocking part 43 rotates, the second protrusion 42 rotates synchronously, releasing the temporary fixing effect on the slider 30, and the slider 30 moves toward the groove 116 under the elastic action of the elastic member 20.

[0049] Please see Figure 8 When the terminal element 200 slides out, the slider 30 loses the supporting effect of the terminal element 200, and the slider 30 returns to its initial position under the elastic action of the elastic element 20.

[0050] The locking assembly 100 provided in this application embodiment allows for automatic locking of the terminal element 200. When the terminal element 200 slides from the slide groove 116 to a preset position, the slider 30 returns to its initial position under the elastic action of the elastic member 20. When unlocking the locking assembly 100, rotating the rotating member 40 unlocks it, and the rotating member 40 temporarily fixes the slider 30, facilitating temporary hand-free operation. After the terminal element 200 disengages from the locking assembly 100, the locking assembly 100 automatically returns to its initial position. The locking assembly 100 is simple to operate during both locking and unlocking processes, making it convenient for users.

[0051] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the above preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solutions of this application should not depart from the spirit and scope of the technical solutions of this application.
