[0065] Referring to Figures 1 to 14 , the sliding cover plate 2 is connected to the body 1 and can be displaced along a second direction d2 and moved between a first position and a second position, the second direction d2 being a direction shown by an arrow d2 as shown in the figure, the second direction d2 being perpendicular to the first direction d1, the sliding cover plate 2 has a lower edge 21, the inner surface of the sliding cover plate 2 is provided with a recessed groove 22 penetrating the lower edge 21 and a through hole 23 provided from the inner bottom wall of the recessed groove 22, and the sliding cover plate 2 has a side edge 24. Figure 1

[0066] Further, the sliding cover plate 2 comprises a connecting plate 25 and an actuating plate 26 extending from one side of the connecting plate 25, and the connecting plate 25 is connected to the body 1. Wherein, the connecting plate 25 and the actuating plate 26 are perpendicular to each other to form an L-shaped plate together, but not limited thereto.

[0067] Specifically, the connecting plate 25 is provided with a plurality of long holes 251 and a plurality of buried grooves 252 along the second direction d2, and each long hole 251 is formed from the inner bottom wall of each buried groove 252.

[0068] Optionally, the actuating plate 26 can slide in the sunken groove 13, the lower edge 21 of the sliding cover plate 2 is formed on the actuating plate 26, the position of the lower inner wall 131 of the sunken groove 13 corresponds to the position of the lower edge 21, the recessed groove 22 and the through hole 23 are formed from the actuating plate 26, and the outer surface of the actuating plate 26 protrudes a pushing part 261. ​​

[0069] Referring to Figures 1 to 8 、 Figures 10 to 13 , the mortise structure 3 is accommodated in the recessed groove 22 and clamped between the body 1 and the sliding cover plate 2, so that the mortise structure 3 is connected to the sliding cover plate 2, the mortise structure 3 moves along with the sliding cover plate 2 in the second direction d2 and can be displaced relative to the sliding cover plate 2 in the first direction d1, the mortise structure 3 has a front latch portion 31 and a pulling portion 32 exposed to the sliding cover plate 2.

[0070] In this embodiment, when the sliding cover plate 2 moves to the second position, the pulling portion 32 can drive the front latch portion 31 to insert and engage in the card slot 11 along the first direction d1. The recessed groove 22 has an inner side wall 221 opposite to the side edge 24, and the inner side wall 221 is provided with a recess 222.

[0071] In this embodiment, in order to clearly understand the specific implementation of the first position and the second position, when the body 1 is provided with an opening, the first position is the position of the sliding cover plate 2 opening the opening, and the second position is the position of the sliding cover plate 2 closing the opening, so that the front latch portion 31 engages in the card slot 11, and the sliding cover plate 2 has been locked by the mortise structure 3 and cannot be moved, that is, the first position is the unlocking position, and the second position is the locking position; or, when the body 1 is installed with a detachable battery or other detachable element, the first position is the position of the sliding cover plate 2 unlocking the detachable element, and the second position is the position of the sliding cover plate 2 locking the detachable element, so that the front latch portion 31 engages in the card slot 11, and the sliding cover plate 2 has been locked by the mortise structure 3 and cannot be moved, that is, the first position is the unlocking position, and the second position is the locking position.

[0072] Specifically, the pulling portion 32 has a neck portion 321 and a head portion 322 extending outward from the neck portion 321, the width a of the through hole 23 measured parallel to or along the first direction d1 is greater than the width h1 of the neck portion 321 measured parallel to or along the first direction d1, and the width b of the through hole 23 measured parallel to or along the second direction d2 is slightly greater than the width h2 of the neck portion 321 measured parallel to or along the second direction d2 and less than the width h3 of the head portion 322 measured parallel to or along the second direction d2, so that the neck portion 321 can be smoothly arranged in the through hole 23, the neck portion 321 slides in the through hole 23 in the first direction d1, but the neck portion 321 is stopped and limited by the sliding cover plate 2 in the second direction d2, so as to guide the neck portion 321 to slide in a straight line along the first direction d1, and the head portion 322 protrudes out of the through hole 23 in the second direction d2 and is stopped and limited by the sliding cover plate 2, so as to prevent the pulling portion 32 from being separated from the through hole 23.

[0073] In this embodiment, if the card structure 3 is to be assembled to the sliding cover plate 2, the card structure 3 can be maneuvered so that the widest part of the head 322 avoids the width of the through hole 23 along the sliding path s, which in this embodiment is the width b. In other words, the head 322 can be selectively passed through the through hole 23 from other angles, and in this embodiment, because the diagonal length of the rectangular through hole 23 is the length of the hypotenuse of the two sides a and b, and this diagonal length is the widest part of the rectangular through hole 23, the widest part of the head 322 can be aligned with the diagonal of the rectangular through hole 23 first, and then the head 322 is adjusted after passing through the through hole 23 so that the rail part 33 is placed against the side edge 24. In addition, the elastic allowance of the material itself can be used during the installation of the card structure 3 to allow the deformation between the head 322 and the rail part 33.

[0074] In summary, through the size cooperation between the through hole 23 and the head 322, and the elasticity of the card structure 3, the card structure 3 can be buckled on the through hole 23 and the side edge 24 of the sliding cover plate 2 by the head 322 and the two rail parts 33 respectively, so that even if the card structure 3 is allowed to slide in the through hole 23, the integrally formed card structure 3 can still be stably installed on the sliding cover plate 2. In addition, because the card structure 3 is clamped between the body 1 and the sliding cover plate 2, the single-piece card structure 3 installed on the sliding cover plate 2 can still ensure that it will not fall off under the premise of being able to slide.

[0075] In this embodiment, the single-piece card structure 3 installed on the sliding cover plate 2 can slide on the through hole 23 and the side edge 24 by the head 322 and the two rail parts 33 respectively, in other words, the card structure 3 slides on the through hole 23 and the side edge 24 as tracks, thereby enabling the card structure 3 to slide in the recessed groove 22 and causing the front latch part 31 to protrude or retract in the lower edge 21, wherein the pulling part 32 is passed through and exposed to the through hole 23 to facilitate user operation.

[0076] Alternatively, the head 322 of this embodiment is a conical body, but it is not limited thereto, and when the head 322 is a conical body, the head 322 can be smoothly passed through the through hole 23 in a way that it is inclined at an angle in front, back, left and right.

[0077] Alternatively, one or more rail parts 33 extend on one side of the card structure 3 and a tactile feedback structure 34 is provided on the other side, the rail part 33 is arranged corresponding to the side edge 24 and is limited and stopped by the side edge 24, and when the front latch part 31 is engaged in the card slot 11, the tactile feedback structure 34 is simultaneously engaged in the recess 222 to emit a click (or creak) sound, reminding that the front latch part 31 has been engaged in the card slot 11, that is, reminding that the sliding cover plate 2 has been locked by the card structure 3 and cannot be moved.

[0078] The present application can also describe the structure of the mortise structure 3 in another way. The mortise structure 3 is adapted to be assembled to the through hole 23 and the side edge 24 of a sliding cover plate 2 to slide between a locked position and an unlocked position and define a sliding path s.

[0079] For example, the specific implementation of the locked position and the unlocked position is clearly understood. The locked position is that the sliding cover plate 2 has been locked by the mortise structure 3 and cannot be moved. The unlocked position is that the sliding cover plate 2 has not been locked by the mortise structure 3 and can be moved.

[0080] In the embodiment, the mortise structure 3 is a plastic part integrally formed. The mortise structure 3 includes a body 30, a front latch part 31, a pulling part 32, two clamping rail parts 33, a tactile feedback structure 34, and a rear latch part 35, all of which integrally extend from the body 30. However, in other embodiments, part of the structure of the mortise structure 3 can be additionally assembled to the body 30. In the embodiment, the front latch part 31 extends downward from the plate-shaped body 30, or in other words, the front latch part 31 is formed by the lower edge structure of the body 30. In the embodiment, the front latch part 31 and the tactile feedback structure 34 jointly form an L-shaped gap, wherein the front latch part 31 can correspond to the clamping groove 11. The pulling part 32 extends forward from the plate-shaped body 30, and the two clamping rail parts 33 also extend forward from the plate-shaped body 30. The mortise structure 3 regards the part of the through hole 23 adjacent to the side edge 24 as a track, and then the mortise structure 3 is installed on the sliding cover plate 2 by using the pulling part 32 and the two clamping rail parts 33 arranged on both sides of the track. The positional relationship between the mortise structure 3 and the sliding cover plate 2 is established by the principle that three points determine a plane, but at least one degree of freedom of displacement is still retained, that is, the mortise structure 3 can slide along the aforementioned track. In the embodiment, the mortise structure 3 linearly slides along the sliding cover plate 2. However, in other embodiments, the sliding path s of the mortise structure 3 is not limited.

[0081] In the embodiment, the pulling part 32 slides in the through hole 23 along the sliding path s by using a neck part 321. The width b of the through hole 23 measured in a direction perpendicular to the sliding path s is matched with the width h2 of the neck part 321 measured in a direction perpendicular to the sliding path s. The pulling part 32 further clamps against the outside of the through hole 23 by using a head part 322. The head part 322 extends outward from the neck part 321, and the width h3 of the head part 322 measured in a direction perpendicular to the sliding path s is greater than the width b of the through hole 23 measured in a direction perpendicular to the sliding path s.

[0082] In the present embodiment, the rail portion 33 extends from the body 30 and is arranged corresponding to the side edge 24, the detent structure 3 is clamped and slides in the through hole 23 and the side edge 24 of the sliding cover plate 2 by the pulling portion 32 and the rail portion 33 respectively. The tactile feedback structure 34 includes a tactile bump 341 extending from the detent structure 3 and a weakened portion 342 formed in the detent structure 3, the tactile bump 341 extends outward from the horizontal side of the plate-shaped body 30, when the detent structure 3 slides back and forth linearly, the tactile feedback structure 34 repeatedly crosses the positioning bump 223 arranged corresponding to the sliding cover plate 2 by the tactile bump 341 to provide the tactile feedback of the buckle positioning, in addition, when the two corresponding bumps interfere with each other, the tactile feedback structure 34 also uses the weakened portion 342 to allow the tactile feedback structure 34 to deform at the tactile bump 341, thereby making the tactile bump 341 easy to cross the positioning bump 223 arranged corresponding to the sliding cover plate 2. See Figure 1 、 Figure 9 、 Figure 14 The present application also includes a plurality of screws 4, each screw 4 has a lock head 41 and a screw rod 42, each screw rod 42 is arranged in each lock hole 12 and each long hole 251, each lock head 41 is limited by the connecting plate 25 to allow the connecting plate 25 to displace in the second direction d2 relative to the plurality of screws 4 through the plurality of long holes 251, and each lock head 41 is embedded in each embedded groove 252.

Figure 1 Figures 5 to 9 ​​​, when the sliding cover plate 2 moves to the second position, the pulling portion 32 can drive the front latch portion 31 to insert and engage in the clamping groove 11 along the first direction d1, so that the sliding cover plate 2 is locked by the clamping structure 3 and cannot move, so that the sliding cover plate 2 presents the state of closing the opening or locking the disassembled component as described above; see Figures 10 to 14 , when the front latch portion 31 is separated from the clamping groove 11, the sliding cover plate 2 can move because it is not locked by the clamping structure 3, and at the same time the reset spring 5 drives the sliding cover plate 2 to move to the first position (the elastic reset position of the reset spring 5), so that the sliding cover plate 2 presents the state of opening the opening or unlocking the disassembled component as described above.

[0086] In the embodiment, the clamping structure 3 can guide the clamping structure 3 to slide in a straight line along the first direction d1 and drive the front latch portion 31 to engage in the clamping groove 11 through the simple structure of the neck portion 321, the head portion 322, the size difference of the through hole 23, and the pulling portion 32 and the clamping rail portion 33 clamping and sliding in the through hole 23 and the side edge 24 of the sliding cover plate 2, so as to achieve the purpose that the sliding cover plate 2 is locked by the clamping structure 3 and cannot move, and further simplify the elements of the clamping structure 3, so that the latching mechanism 10 has the effects of preventing the sliding cover plate 2 from being opened due to accidental touch, vibration or impact, simple assembly structure, reduced accommodation space and reduced manufacturing cost.

[0087] Referring to Figures 5 to 7 , Figures 10 to 14 , the clamping structure 3 extends the pulling portion 32 on one side and extends the rear latch portion 35 on the other side, and the rear latch portion 35 extends backward from the plate-shaped body 30. In the embodiment, in order to meet the physical limitation of injection molding, the rear latch portion 35 adopts a C-shaped or G-shaped structure with uniform thickness, and a gap of the C-shaped or G-shaped structure forms a gap 351. When the front latch portion 31 and the rear latch portion 35 are accommodated in the clamping groove 11, the sliding wall 16 protrudes a spinous process 162 corresponding to the gap 351, and the spinous process 162 can slide along the lower edge guide angle of the C-shaped or G-shaped structure of the rear latch portion 35 to the gap 351 and engage in the gap 351. However, in other embodiments, the specific shape of the rear latch portion 35 is not limited.

[0088] In the embodiment, the body 1 is provided with a sliding wall 16 beside the clamping groove 11, and one side of the clamping structure 3 relative to the tactile feedback structure 34 can slide along the sliding wall 16. The sliding wall 16 is also provided with a sliding groove 161 corresponding to the outside of the clamping rail portion 33, and the clamping structure 3 can rely on the two clamping rail portions 33 in the sliding groove 161, thereby increasing the stability of linear sliding. In addition, one side of the C-shaped or G-shaped rear latch portion 35 of the clamping structure 3 can also slide along the sliding wall 16, and the clamping structure 3 can rely on the rear latch portion 35 on the sliding wall 16, thereby increasing the stability of linear sliding. The lower edge of the rear latch portion 35 is cut to the lower edge of the front latch portion 31, and the body 1 is provided with corresponding clamping grooves 11 corresponding to the front latch portion 31 and the rear latch portion 35.

[0089] In this embodiment, when the card structure 3 is leaning against the sliding wall 16, and the card slot 11 contains the front latch part 31 and the rear latch part 35, the card structure 3 can play a locking function, so that the sliding cover plate 2 cannot slide. If the sliding cover plate 2 is forced to slide, the card structure 3 may be rotated and deviated from the track. However, because the spines 162 corresponding to the accommodation openings 351 of the body 1 are located in the accommodation openings 351, and further abut against one end of the C-shaped or G-shaped structure, and the rear latch part 35 of the C-shaped or G-shaped structure abuts against the sliding wall 16, and the two card rail parts 33 abut against the sliding groove 161, the rotation or deviation of the card structure 3 caused by the misalignment between the body 1 and the sliding cover plate 2 can be avoided, thereby increasing the overall stability of the latch mechanism 10.

[0090] In this embodiment, the card structure 3 is provided with a niche 36 on the body 30, which can be filled with red ink or embedded with red bricks to attract attention. When the card structure 3 is in the unlocked position, the niche 36 is exposed in the through hole 23, thereby reminding the user that the sliding cover plate 2 has not been locked.
