As shown in fig. 1 to 5a, the terminal device 10 includes a latch structure 1, a first member 2, a second member 3, a rear cover 4, and a rear case 5. The latch structure 1 is used for connecting a first element 2 and a second element 3, the first element 2 is arranged on the rear cover 4, the second element 3 is arranged on the rear shell 5, the first element 2 and the second element 3 are two elements which need to be connected, materials, outline, dimension specification and the like of the two elements can be flexibly arranged, and the latch structure can be flexibly selected according to the outline design of the terminal equipment 10, of course, the first element 2 and the second element 3 can be only partial components of certain parts.

It can be appreciated that, since the first element 2 is disposed on the rear cover 4 and the second element 3 is disposed on the rear housing 5, the rear cover 4 and the rear housing 5 can also be locked or unlocked in relative positions by the latch structure 1.

It should be noted that, in some embodiments, the first element 2 may be fixedly connected to the rear cover 4 by an adhesive, welding, screwing, or clamping, and the second element 3 may be fixedly connected to the rear case 5 by an adhesive, welding, screwing, or clamping. The first element 2 may in some embodiments be configured to be integrally formed with the rear cover 4 and the second element 3 may in some embodiments be configured to be integrally formed with the rear housing 5.

As shown in fig. 3 to 8, the latch structure 1 includes a first limiting component 11, a second limiting component 12 and a movable component 13, where the first limiting component 11 is disposed on the first element 2, and the second limiting component 12 is disposed on the second element 3. The first limiting member 11 and the second limiting member 12 together function to limit the movable range of the movable member 13 on the one hand, and also function to limit the removal of the movable member 13 on the other hand.

The first limiting assembly 11 comprises a movable aperture 111 provided on the first element 2, the movable aperture 111 having a locking position 1112 and an unlocking position 1113.

The second limiting assembly 12 comprises a fixing hole 121 arranged on the second element 3, and an anti-falling piece 122 is arranged on the hole wall of the fixing hole 121.

The movable assembly 13 comprises a movable piece 131 penetrating through the movable hole 111, a limiting part 132 arranged on the movable piece 131 and an anti-falling part 133 arranged on the movable piece; the limiting portion 132 penetrates through the movable hole 111 and abuts against the first element 2, so as to limit the movable piece 131 to deviate from the movable hole 111.

It will be appreciated that the movable hole 111 is used for the movable member 131 to pass through, and also is used for limiting the movable member 131 to move only within the area defined by the wall of the movable hole 111. The locking position 1112 and the unlocking position 1113 can both enable the movable member 131 to move therein, so as to lock and unlock the movable member 131, and in the locked state, the movable member 131 is limited to be pulled out, and in the unlocked state, the movable member 131 can be pulled out freely.

The fixing hole 121 is used for inserting the movable member 131 therein, and the falling-off preventing member 122 is used for limiting the limiting portion 132 in the fixing hole 121, thereby preventing the movable member 131 from exiting the fixing hole 121.

The movable member 131 drives the limiting portion 132 and the anti-falling portion 133 to move synchronously, and in the case that the position of the movable member 131 is limited, the position of the first element 2 penetrated by the movable member 131 is limited. The limiting portion 132 is used for preventing the movable member 131 from being separated from the movable hole 111, so that the movable member 131 is limited on the first element 2 to perform movement, and the movable member 131 is prevented from being separated from the first element 2. The escape prevention part 133 serves to prevent the movable member 131 from escaping from the fixing hole 121.

It should be noted that, the removal of the movable member 131 means that the movable member 131 may be withdrawn from the corresponding position, so that the first element 2 and the second element 3 may be separated. The anti-falling member 122 may be a hole, a slot, a protrusion, a screw, etc., as long as the movable member 131 drives the anti-falling portion 133 to move to the locking position 1112 and then can be limited by the anti-falling member 122; for example, if the anti-falling member 122 is configured as a hole or a slot, when the movable member 131 is located at the locking position 1112, the anti-falling portion 133 is inserted into the corresponding hole or slot, so that the anti-falling portion 133 cannot be out of the restriction of the anti-falling member 122 configured as the hole or slot, and the movable member 131 cannot be out of the fixing hole 121, and finally the fixing of the first element 2 and the second element 3 is completed; for example, if the retaining member 122 is configured as a protrusion, a screw, or the like, when the movable member 131 is positioned at the locking position 1112, the retaining portion 133 is aligned with the retaining member 122 configured as a protrusion or a screw, so that the retaining portion 133 is retained by the retaining member 122, and the movable member 131 can be prevented from coming out of the fixing hole 121, and finally the purpose of fixing the relative positions of the first element 2 and the second element 3 can be achieved.

It should be further noted that the locking position 1112 and the unlocking position 1113 may be merely spatially divided or named, and no structure or element or the like for distinguishing the locking position 1112 from the unlocking position 1113 may exist in the movable hole 111. Of course, marks corresponding to the locking position 1112 and the unlocking position 1113 may be added on the rear housing 5 or the second element 3, and the marks may be configured as icons, slots, holes, or the like.

When the movable member 131 slides or rotates to the locking position 1112, the retaining member 122 defines the retaining portion 133 to be removed from the fixing hole 121, and when the movable member 131 slides or rotates to the unlocking position 1113, the retaining portion 133 releases the definition of the retaining member 122.

It can be understood that the moving manner of the moving member 131 in the moving hole 111 may be sliding or turning to the east, and the moving manner of the moving member 131 may be different depending on the structure of the moving hole 111, for example, the moving hole 111 is configured as an elongated waist hole or a shape similar to the waist hole, and the moving member 131 is configured to slide along the hole wall of the moving hole 111; for another example, if the movable hole 111 is configured as a circular hole or is approximately in the shape of a circular hole, the movable member 131 is configured to be switched between the locking position 1112 and the unlocking position 1113 by rotating.

As shown in fig. 3 to 8, in some embodiments, the fixed hole 121 has an insertion position 1211 into which the movable member 131 is inserted and a defining position 1212 in which the movable member 131 is defined to be pulled out, and the drop preventing member 122 is located at the drop preventing position.

It should be understood that the space occupied by the insertion position 1211 and the limiting position 1212 may be the same or different, that is, the movable member 131 may be inserted in a wide range of the fixing hole 121, and the anti-releasing member 122 may limit the anti-releasing portion 133 and prevent the anti-releasing portion 133 from releasing.

As shown in fig. 6 and 7, in some embodiments, a thickness compensating portion 1111 is disposed on a wall of the movable hole 111, and when the movable member 131 slides or rotates to the locking position 1112, the thickness compensating portion 1111 is movably abutted against the limiting portion 132, so as to limit the limiting portion 132 from falling out of the movable hole 111.

It will be appreciated that the width of the part of the movable hole 111 is reduced due to the provision of the thickness-compensating portion 1111, and therefore, the fit clearance between the limiting portion 132 and the wall of the movable hole 111 is reduced at the position where the thickness-compensating portion 1111 is provided, thereby effectively preventing the limiting portion 132 from being removed from the position where the width is smaller, that is, preventing the limiting portion 132 from being removed from the position where the thickness-compensating portion 1111 is provided.

The thickness-compensating portion 1111 and the first element 2 may be integrally formed together, or may be configured to be connected by a post-assembly method. When the movable member 131 is assembled, the movable member 131 can be aligned to the unlocking position 1113 for installation, so that the limit part 132 is prevented from penetrating through a narrower position in the movable hole 111, and the assembly efficiency is improved. The provision of the thickness-compensating portion 1111 can enhance the stability of the engagement of the movable member 131 and the first limiting member 11 in the locked state when the movable member 131 is moved to the locking position 1112.

As shown in fig. 6 and fig. 7, in some embodiments, a plurality of thickness compensating portions 1111 are disposed on the wall of the movable hole 111, and the movable assembly 13 includes a plurality of limiting portions 132 disposed on the movable member 131, where each limiting portion 132 is movably supported by each thickness compensating portion 1111 in a one-to-one correspondence.

It can be appreciated that the arrangement of the thickness compensating portions 1111 and the limiting portions 132 can jointly limit the withdrawal of the movable member 131 from a plurality of different positions, so as to further improve the stability of the cooperation of the movable member 131 and the first limiting assembly 11 in the locked state.

It should be noted that, when the limiting portions 132 interact to the locking position 1112, each limiting portion 132 will be propped against one thickness compensating portion 1111.

Further, each of the limiting portions 132 is disposed on the movable member 131 in a laterally symmetrical manner.

As shown in fig. 3 to 8, in some embodiments, the limiting portion 132 extends laterally at an end far from the movable member 131 to form a limiting protrusion 1321, and the limiting protrusion 1321 movably abuts against the first element 2 to limit the limiting portion 132 from being separated from the movable hole 111.

As can be appreciated, the stop protrusions 1321 serve to prevent the stop 132 from coming out of the movable hole 111. The stop protrusion 1321 and the stop portion 132 may be configured to be connected to each other in an L shape or a substantially L shape. The limiting protrusion 1321 and the limiting portion 132 may be connected by bonding, welding, clamping or screwing, or may be integrally formed together.

As shown in fig. 3 to 7, in some embodiments, the first limiting assembly 11 further includes a positioning piece 112 disposed on the first element 2, an end of the positioning piece 112 extends into the movable hole 111, and an end of the positioning piece 112 is provided with a positioning portion 1121.

Two positioning grooves 1311 are formed in the movable member 131, the positioning portion 1121 is correspondingly inserted into one of the positioning grooves 1311 when the movable member 131 is located at the locking position, and the positioning portion 1121 is correspondingly inserted into the other positioning groove 1311 when the movable member 131 is located at the unlocking position.

As can be appreciated, the positioning piece 112 is used to support the positioning portion 1121. The positioning portion 1121 is configured to be engaged in the positioning groove 1311, thereby clamping the movable member 131, and thereby preventing the movable member 131 from being displaced to some extent, that is, enabling the movable member 131 to be more stably fixed in the locking position 1112 and the unlocking position 1113. The outline of the positioning portion 1121 may be configured to be adapted to the outline of the groove wall of the positioning groove 1311, so as to increase the contact area between the positioning portion 1121 and the groove wall of the positioning groove 1311, and further prevent the movable member 131 from being shifted.

Further, the positioning sheet 112 may be configured to have a certain resetting performance. Thus, at the moment of sliding to the locking position 1112 or the unlocking position 1113, the positioning piece 112 drives the positioning portion 1121 to reset instantaneously, and the positioning portion 1121 falls into the positioning groove 1311 instantaneously. Thus, the feel of the user operating the movable member 131 can be improved, and the operation suitability of the product can be improved.

As shown in fig. 3 to 7, in some embodiments, the first limiting assembly 11 further includes a sliding groove 113 disposed on the first element 2, the movable hole 111 is located at a bottom of the sliding groove 113, a length extending direction of the sliding groove 113 is consistent with a length extending direction of the movable hole 111, and a width of the sliding groove 113 is matched with a width of the movable member 131.

It can be appreciated that the limitation of the sliding groove 113 makes the movable member 131 slide only along the groove wall of the sliding groove 113, and since the length extending direction of the sliding groove 113 is consistent with the length extending direction of the movable hole 111, that is, the movable member 131 can slide only along the length extending direction of the movable hole 111, so that the movable member 131 is prevented from rotating due to the lack of guiding of the groove wall of the sliding groove 113, and the movable member 131 is ensured to slide to the locking position 1112 or the unlocking position 1113 in a correct direction, and misoperation is avoided.

As shown in fig. 3-7, in some embodiments, a toggle stripe 1312 is provided on the movable member 131.

It will be appreciated that the provision of the toggle stripes 1312 prevents slippage from occurring when the user toggles the moveable member 131.

As shown in fig. 2, in some embodiments, the rear case 5 is provided with a battery mounting groove 51, and the rear cover 4 shields or opens the battery mounting groove 51; the back shell 5 is also provided with a hanging hole 52 for the hanging rope to pass through.

It will be appreciated that the battery mounting groove 41 is provided to avoid the space available for mounting a battery, and the hanging hole 52 is provided for the hanging rope to pass through, thereby being convenient for a user to carry.
