[0047] This utility model provides an electronic device. Figures 6 to 17 A preferred embodiment of the electronic device provided by this utility model is shown.

[0048] Please see Figure 6 , Figure 12 , Figure 13 and Figure 17In this embodiment, the electronic device 100 includes a first body 1, a latch 2, a movable latch 3, and a second body 4. The first body 1 is provided with a rotatable latch 2, and the latch 2 is provided with a first engaging portion 21. The movable latch 3 is movably disposed on the latch 2, and the movable latch 3 is provided with a second engaging portion 31. The second body 4 is provided with a first snap-fit ​​portion 41, and the second body 4 is detachably connected to the first body 1. The second body 4 or the first body 1 is provided with a second snap-fit ​​portion 11. When the electronic device 100 is in a locked state (see [reference]...), Figures 6 to 8 The first main body 1 is connected to the second main body 4, the latch 2 is in the first position, the first engaging part 21 is latched to the first engaging part 41, the movable latch 3 is in the first movable position, and the second engaging part 31 is latched to the second engaging part 11 to restrict the rotation of the latch 2; when the electronic device 100 is in the unlocked state (see [reference]). Figure 9 and Figure 10 The first main body 1 is connected to the second main body 4, the latch 2 is in the first position, the movable latch 3 is in the second movable position, and the second engaging part 31 is separated from the second engaging part 11; when the electronic device 100 is in the unlocked state (see [reference]). Figure 11 The latch 2 is in the second position, and the first body 1 and the second body 4 can be separated.

[0049] Specifically, the first main body 1 and the second main body 4 are detachably connected by a latch 2. When the first main body 1 and the second main body 4 are connected, they are spliced ​​together to form the electronic device 100. The first main body 1 and the second main body 4 can be spliced ​​along the height direction of the electronic device 100; the first main body 1 and the second main body 4 can also be spliced ​​along the length direction of the electronic device 100; the first main body 1 and the second main body 4 can also be spliced ​​along the width direction of the electronic device 100. The following will take the splicing of the first main body 1 and the second main body 4 along the height direction of the electronic device 100 as an example.

[0050] The latches 2 are rotatably mounted on the first body 1. The specific number and position of the latches 2 can be set according to the actual situation. There can be one, two, three, four, or more latches 2. For example, two latches 2 can be provided on each side of the first body 1 along the length direction of the electronic device 100; or two latches 2 can be provided on each side of the first body 1 along the width direction of the electronic device 100. The following description will take the example of two latches 2 on each side of the first body 1 along the width direction of the electronic device 100, with each latch 2 rotatably mounted on the first body 1 along the axis along the length direction of the electronic device 100.

[0051] One end of the latch 2 is rotatably connected to the first body 1, and the other end of the latch 2 is provided with a first engaging part 21. A first engaging part 41 is provided on the second body 4 corresponding to the first engaging part 21. Within the movement range of the latch 2 relative to the first body 1, the latch 2 has a first position and a second position. When the first body 1 and the second body 4 are connected, the latch 2 is rotated to the first position. At this time, the first engaging part 21 on the latch 2 engages with the first engaging part 41 on the second body 4 to prevent the first body 1 from separating from the second body 4. When the first body 1 and the second body 4 are connected and the latch 2 is in the first position, the latch 2 is rotated to the second position. At this time, the engagement between the first engaging part 21 and the first engaging part 41 fails, and they separate, allowing the first body 1 and the second body 4 to separate.

[0052] Each latch 2 is provided with a movable latch 3, and the movable latch 3 is provided with a second engaging part 31. A second engaging part 11 is provided on either the first body 1 or the second body 4 corresponding to the second engaging part 31. The second engaging part 11 can be provided on the first body 1; the second engaging part 11 can also be provided on the second body 4. Optionally, please refer to... Figure 8 , Figure 10 and Figure 13 In this embodiment, the second snap-fit ​​portion 11 is disposed on the first main body 1. The movable buckle 3 is disposed on the latch 2, and the latch 2 is located on the first main body 1. The second snap-fit ​​portion 11 is disposed on the first main body 1, so that the second snap-fit ​​portion 11 can be disposed close to the movable buckle 3, which is conducive to the second snap-fit ​​portion 11 and the second fastening portion 31 on the movable buckle 3 forming a snap-fit ​​connection. The following will describe the example of the second snap-fit ​​portion 11 being disposed on the first main body 1.

[0053] Within the travel range of the movable buckle 3 relative to the locking buckle 2, the movable buckle 3 has a first movable position and a second movable position. When the first body 1 and the second body 4 are connected, and the locking buckle 2 is in the first position, the movable buckle 3 is moved to the first movable position. At this time, the second engaging part 31 on the movable buckle 3 is engaged with the second locking part 11 on the first body 1 to restrict the rotation of the locking buckle 2 in the first position, thereby preventing the locking buckle 2 from popping open when the electronic device 100 is subjected to external impact or dropped. When the first body 1 and the second body 4 are connected, and the locking buckle 2 is in the first position and the movable buckle 3 is in the first movable position, the movable buckle 3 is moved to the second movable position. At this time, the second engaging part 31 and the second locking part 11 lose their engagement and separate, thereby releasing the rotation restriction on the locking buckle 2 in the first position, allowing the user to rotate and open the locking buckle 2 normally.

[0054] Since both latch 2 and movable latch 3 are movable, the electronic device 100 can have multiple states, including a locked state, an unlocked state, and a disengaged state. When the electronic device 100 is in the locked state, the first body 1 is connected to the second body 4, latch 2 is in the first position, and movable latch 3 is in the first movable position. When the electronic device 100 is in the unlocked state, the first body 1 is connected to the second body 4, latch 2 is in the first position, and movable latch 3 is in the second movable position. When the electronic device 100 is in the disengaged state, latch 2 is in the second position, and the first body 1 and the second body 4 can be separated.

[0055] The electronic device 100 of this utility model adds a movable buckle 3 to the latch 2. After the latch 2 is installed and locked in place, the movable buckle 3 is moved to the first movable position so that the second locking part 31 on the movable buckle 3 is locked to the second locking part 11 on the main body (first main body 1 or second main body 4), thereby restricting the movement of the latch 2 in the rotation direction. This makes the latch structure of the electronic device 100 safer and more reliable, and avoids the problem of the latch 2 popping open when the electronic device 100 is subjected to external impact or dropped.

[0056] The latch 2 is rotatably mounted on the first body 1 along the axis of the electronic device 100 in the length direction. Optionally, please refer to... Figures 11 to 13 In this embodiment, a connecting rod 5 is provided between the first main body 1 and the latch 2. The middle part of the connecting rod 5 is rotatably connected to the first main body 1. Both ends of the connecting rod 5 are bent relative to the middle part to form an included angle of about 90°. Both ends of the connecting rod 5 are rotatably connected to the latch 2.

[0057] Specifically, the connecting rod 5 is typically made of metal, and both the connecting rod 5 and the latch 2 extend along the length of the electronic device 100. A rotating connecting seat protrudes from the first main body 1 along the length of the electronic device 100, and the middle portion of the connecting rod 5 is rotatably positioned at the rotating connecting seat. Both ends of the connecting rod 5 are bent and extend in mutually distancing directions to form two rotating connecting portions, which are rotatably connected to both ends of the latch 2, respectively.

[0058] The latch 2 and the second main body 4 are respectively provided with a first engaging part 21 and a first engaging part 41 for snap-fit ​​connection. The specific number and shape of the first engaging part 21 and the first engaging part 41 can be set according to the actual situation. For example, one of each of the first engaging part 21 and the first engaging part 41 is provided, and both of the first engaging part 21 and the first engaging part 41 are arranged in a long strip shape extending along the length direction of the electronic device 100; or, one of the first engaging part 21 and the first engaging part 41 is provided, and is arranged in a long strip shape extending along the length direction of the electronic device 100, while multiple of the other are arranged at intervals along the length direction of the electronic device 100.

[0059] The specific styles of the first fastening part 21 and the first snap-fit ​​part 41 can also be set according to the actual situation. For example, one of the first fastening part 21 and the first snap-fit ​​part 41 is a snap protrusion and the other is a snap groove; or, the first fastening part 21 and the first snap-fit ​​part 41 are respectively the first hook and the second hook. When the first body 1 and the second body 4 are connected and the latch 2 is in the first position, the first hook and the second hook are oriented in the height direction of the electronic device 100 and opposite to each other, and the first hook and the second hook are fastened in the width direction of the electronic device 100.

[0060] The movable buckle 3 is movably mounted on the latch 2. The movable buckle 3 can be flipped or slidably mounted on the latch 2. When the movable buckle 3 is slidably mounted on the latch 2, the sliding direction of the movable buckle 3 can be parallel or approximately parallel to the direction of the rotation axis of the latch 2; the sliding direction of the movable buckle 3 can also intersect the direction of the rotation axis of the latch 2; the sliding direction of the movable buckle 3 can also be an arc, a wavy line, or a broken line, etc.

[0061] Optionally, please refer to Figures 7 to 10 In this embodiment, the movable buckle 3 is slidably disposed on the latch 2 along the direction of the rotation axis of the latch 2. This movable buckle 3 has a relatively simple movement mode, and the sliding direction of the movable buckle 3 is the length direction of the electronic device 100. This makes full use of the installation space between the latch 2 and the first body 1 in the length direction, thereby facilitating the placement of the movable buckle 3 on the latch 2 and the placement of the second snap-fit ​​part 11 on the first body 1.

[0062] Optionally, please refer to Figures 14 to 16 In this embodiment, the movable buckle 3 is provided with a groove 33 extending along the sliding direction of the movable buckle 3, and the latch 2 is provided with a protruding post 24. The protruding post 24 extends into the groove 33 and forms a sliding guide engagement with the groove 33 in the sliding direction of the movable buckle 3.

[0063] Specifically, the movable buckle 3 has a groove 33 extending along the length of the lock 2 on its surface near the latch 2, and the groove 33 penetrates the surface of the movable buckle 3 away from the lock 2. A protruding post 24 protrudes from the surface of the lock 2 near the movable buckle 3, at least a portion of which extends into the groove 33. The protruding post 24 and the groove 33 form a sliding guide engagement in the sliding direction of the movable buckle 3. Thus, through the sliding engagement of the protruding post 24 and the groove 33, the movable buckle 3 can be slidably guided in the length direction of the lock 2.

[0064] The protruding post 24 and the sliding groove 33 can be provided one or more in a one-to-one correspondence. Optionally, please refer to [reference needed]. Figures 14 to 16In this embodiment, the movable buckle 3 is provided with two sliding grooves 33 arranged at intervals along the length direction of the buckle 2. Correspondingly, the buckle 2 is provided with two protrusions 24. The two protrusions 24 extend into the two sliding grooves 33 respectively, and the two protrusions 24 and the two sliding grooves 33 respectively form a sliding guide engagement in the sliding direction of the movable buckle 3.

[0065] Optionally, please refer to Figures 14 to 16 In this embodiment, a screw 25 is provided on the protruding post 24, and the head of the screw 25 is located on the side of the movable buckle 3 away from the latch 2.

[0066] Specifically, a threaded hole is provided on the top surface of the protrusion 24. The tail of the screw 25 is screwed into the threaded hole on the protrusion 24 from the side of the movable buckle 3 away from the lock buckle 2, while the head of the screw 25 abuts against the surface of the movable buckle 3 away from the lock buckle 2. In this way, the movable buckle 3 is fixed to the lock buckle 2 by the screw 25, so as to prevent the movable buckle 3 from separating from the lock buckle 2.

[0067] Optionally, please refer to Figure 8 , Figure 10 and Figure 15 In this embodiment, one of the movable buckle 3 and the locking buckle 2 is provided with a limiting part 32, and the other is provided with a first mating part 22 and a second mating part 23 at intervals along the sliding direction of the movable buckle 3; when the movable buckle 3 is in the first movable position, the limiting part 32 and the first mating part 22 form a limiting fit in the sliding direction of the movable buckle 3; when the movable buckle 3 is in the second movable position, the limiting part 32 and the second mating part 23 form a limiting fit in the sliding direction of the movable buckle 3.

[0068] Specifically, the limiting part 32 can be provided on the movable buckle 3, while the first mating part 22 and the second mating part 23 are provided on the latch 2; alternatively, the limiting part 32 can be provided on the latch 2, while the first mating part 22 and the second mating part 23 are provided on the movable buckle 3. The following description will use the example of the limiting part 32 being provided on the movable buckle 3, while the first mating part 22 and the second mating part 23 are provided on the latch 2.

[0069] When the movable buckle 3 is in the first active position, the limiting part 32 on the movable buckle 3 and the first mating part 22 on the latch 2 form a limiting engagement to restrict the sliding of the movable buckle 3, thereby limiting the movable buckle 3 in the first active position. When the user moves the movable buckle 3 towards the second active position, the limiting part 32 and the first mating part 22 separate, allowing the movable buckle 3 to slide normally. When the movable buckle 3 slides to the second active position, the limiting part 32 and the second mating part 23 on the latch 2 form a limiting engagement to restrict the sliding of the movable buckle 3, thereby limiting the movable buckle 3 in the second active position.

[0070] The specific designs of the limiting part 32, the first mating part 22, and the second mating part 23 can also be set according to actual conditions. For example, the limiting part 32, the first mating part 22, and the second mating part 23 can be a concave-convex limiting structure or a magnetic limiting structure, etc. Optionally, please refer to Figure 8 , Figure 10 , Figure 15 and Figure 16 In this embodiment, the limiting part 32 is a protrusion 32a, the first mating part 22 and the second mating part 23 are the first limiting groove 22a and the second limiting groove 23a, respectively; when the movable buckle 3 is in the first movable position, the protrusion 32a extends into the first limiting groove 22a; when the movable buckle 3 is in the second movable position, the protrusion 32a extends into the second limiting groove 23a.

[0071] Specifically, the limiting part 32, the first mating part 22, and the second mating part 23 are respectively a protrusion 32a, a first limiting groove 22a, and a second limiting groove 23a, forming a concave-convex limiting structure. This sliding limiting structure of the movable buckle 3 has the advantage of simple structure. The cross-sectional shapes of the limiting part 32, the first mating part 22, and the second mating part 23 are usually compatible. For example, the cross-sectional shapes of the limiting part 32, the first mating part 22, and the second mating part 23 can all be triangular, trapezoidal, or arc-shaped.

[0072] Further, please refer to Figure 8 , Figure 10 , Figure 15 and Figure 16 In this embodiment, the limiting part 32, the first mating part 22, and the second mating part 23 all extend along the width direction of the latch 2. This arrangement enables the limiting structure to effectively limit the sliding movement of the movable latch 3.

[0073] Optionally, please refer to Figure 16 In this embodiment, the movable buckle 3 is provided with a spring arm portion 35, and a protrusion 32a is provided at the free end of the spring arm portion 35.

[0074] Specifically, the movable buckle 3 has an n-shaped through groove on its surface near the latch 2, forming a spring arm 35 around it. A limiting part 32 is positioned at the free end of the spring arm 35, allowing the spring arm 35 to deform as the protrusion 32a slides back and forth between the first limiting groove 22a and the second limiting groove 23a, thus moving the protrusion 32a away from the latch 2. When the spring arm 35 returns to its original shape, it also deforms, causing the protrusion 32a to enter either the first limiting groove 22a or the second limiting groove 23a. This allows the user to slide the movable buckle 3 back and forth between the first and second movable positions with relatively little effort.

[0075] Optionally, please refer to Figure 8 , Figure 10 and Figure 12 In this embodiment, the movable buckle 3 is disposed on the surface of the latch 2 near the first body 1 in the rotational fastening direction. The latch 2 is provided with a mounting groove 26. The movable buckle 3 is provided with a toggle part 34 protruding from the surface of the latch 2. The toggle part 34 extends into the mounting groove 26 so as to toggle the movable buckle 3.

[0076] Specifically, the latch 2 has a mounting groove 26 that extends through the surface of the latch 2 near the movable latch 3 and the surface away from the movable latch 3. The movable latch 3 is located on the surface of the latch 2 near the first body 1, and the actuating part 34 on the movable latch 3 extends into the mounting groove 26, so that the user can slide the movable latch 3 by actuating part 34.

[0077] The specific design of the second snap-fit ​​part 11 and the second fastening part 31 can also be set according to the actual situation. For example, the second snap-fit ​​part 11 and the second fastening part 31 can both be hooks; or, for example, one of the second snap-fit ​​part 11 and the other of the second fastening part 31 can be a slot and the other can be a protrusion.

[0078] Optionally, please refer to Figure 8 , Figure 10 , Figure 12 and Figure 16 In this embodiment, the second engaging part 31 is a locking tongue 31a, which is disposed at one end of the movable buckle 3 near the second engaging part 11 in the sliding direction of the movable buckle 3. The second engaging part 11 is a slot 11a with the slot facing the movable buckle 3. When the movable buckle 3 is in the first active position, the locking tongue 31a extends into the slot 11a. When the movable buckle 3 is in the second active position, the locking tongue 31a is outside the slot 11a.

[0079] Specifically, a boss is provided on the surface of the first main body 1 near the latch 2. The boss is located on one side of the movable buckle 3 in the sliding direction of the movable buckle 3. A groove 11a is formed on the surface of the boss near the movable buckle 3 to form a second engaging part 11. The opening of the groove 11a faces the movable buckle 3. The end of the movable buckle 3 near the boss first bends and extends away from the latch 2 and then towards the boss to form a locking tongue 31a. The locking tongue 31a constitutes the second engaging part 31.

[0080] After the latch 2 is engaged with the second body 4, when it is necessary to lock the latch 2, the movable latch 3 is moved to the first movable position. The deformation of the protrusion 32a changes its position, causing the locking tongue 31a at the end of the movable latch 3 to insert into the slot 11a on the first body 1, thereby restricting the rotational movement of the latch 2. When it is necessary to unlock the latch 2, the movable latch 3 is moved to the second movable position. The deformation of the protrusion 32a changes its position, causing the locking tongue 31a at the end of the movable latch 3 to disengage from the slot 11a on the first body 1, thus releasing the restriction on the latch 2 and allowing it to be unlocked.

[0081] Optionally, please refer to Figure 6 , Figure 12 and Figure 17 In this embodiment, a first electrical connection part 12 is provided on the first main body 1, and a second electrical connection part 42 is provided on the second main body 4; when the first main body 1 and the second main body 4 are connected, the first electrical connection part 12 and the second electrical connection part 42 abut against each other to electrically connect the first main body 1 and the second main body 4.

[0082] Specifically, when the first body 1 and the second body 4 are connected, the first body 1 and the second body 4 make conductive contact through the first electrical connection part 12 and the second electrical connection part 42, thereby realizing the electrical connection between the first body 1 and the second body 4.

[0083] Further, please refer to Figure 6 , Figure 12 and Figure 17 In this embodiment, one of the first main body 1 and the second main body 4 is the main device, and the other is the battery box.

[0084] Specifically, the first main body 1 can be a main device such as a tracker, while the second main body 4 is a battery box; alternatively, the first main body 1 can be a battery box, while the second main body 4 is a main device such as a tracker. Since the main device and the battery box are detachably connected, the user can replace the battery box according to the actual situation.

[0085] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
