DETAILED DESCRIPTION

[0026] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , an embodiment of the utility model provides an imaging device, comprising a main body 2 and a mounting module 1 installed on the main body 2, and further comprising a guide structure and a positioning structure, wherein the main body 2 has a recessed portion b for the protrusion a of the mounting module 1 to be detachably inserted, and the guide structure and the positioning structure are both arranged on the mating surfaces of the recessed portion b and the protrusion a. In this embodiment, by designing a guide structure and a positioning structure on the mating surfaces of the main body 2 and the mounting module 1, when the mounting module 1 is assembled to the main body 2, the guide structure and the positioning structure can respectively play a guiding and positioning role, wherein the guide structure can realize the blind insertion of the mounting module 1 on the main body 2, thereby improving the assembly efficiency and assembly accuracy, and the positioning structure can ensure that the mounting module 1 is inserted into place, thereby improving the assembly efficiency and assisting the conduction between the mounting module 1 and the main body 2. Specifically, as Figure 1 and Figure 2As shown, along the direction of the arrow, the protrusion a of the mounting module 1 is inserted into or pulled out of the recessed portion b of the host 2. The prior art only uses plane-matching plugging and unplugging, which may cause misalignment and inconvenience in plugging and unplugging, and blind plugging cannot be achieved. However, this embodiment cleverly solves this technical problem by designing a guiding structure and a positioning structure on the mating surfaces of the protrusion a and the recessed portion b.

[0028] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The guide structure includes a boss 41 and a groove 42 for inserting the boss 41. Along the direction of inserting the installation module 1 into the host 2, the column width of the boss 41 gradually decreases, the groove width of the groove 42 is evenly spaced, and the groove width of the groove 42 is equal to the column width of the end of the boss 41 that finally contacts the groove 42. In this embodiment, the above-mentioned guiding structure is refined. Along the direction of inserting the installation module 1 into the host 2, or when the boss 41 is gradually inserted into the groove 42, along the direction from the boss 41 first contacting one end of the groove 42 to the boss 41 later contacting one end of the groove 42, the column width of the boss 41 is designed to be gradually reduced, while the groove 42 maintains the same groove width, that is, it is a straight groove, and the column width of the upper part of the boss 41, that is, the end that last contacts the groove 42, is consistent with the groove width of the groove 42. Then, when the boss 41 is inserted into the groove 42, the smaller end of the boss 41 enters the groove 42 first and can be directly inserted without centering. As the column width of the boss 41 gradually increases, it will naturally be guided in the groove 42 until the widest part of the boss 41 is completely matched with the groove 42. At this time, the insertion is completed, and the interface of the installation module 1 and the interface of the host 2 can also be instantly docked, realizing blind insertion between the two. Preferably, the boss 41 is provided on the protruding portion a, and the groove 42 is provided on the recessed portion b; or the boss 41 is provided on the recessed portion b, and the groove 42 is provided on the protruding portion a. In this embodiment, as to whether the boss 41 and the groove 42 are respectively provided on the protruding portion a or designed on the recessed portion b, this embodiment does not impose any restriction on this.

[0029] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The guide structure further includes a first inclined surface 43 and a second inclined surface 44 disposed in contact with the first inclined surface 43. The first inclined surface 43 and the second inclined surface 44 gradually taper as the installation module 1 is inserted into the host 2. In this embodiment, for more precise guidance, two inclined surfaces can be designed to cooperate, and the inclined surfaces and the aforementioned protrusions 41 or grooves 42 can be arranged side by side on the mating surface.

[0030] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , the positioning structure includes a positioning block 51 and a positioning groove 52 for the positioning block 51 to be inserted into, and the positioning block 51 and the positioning groove 52 are both provided on the mating surface. In this embodiment, the above-mentioned positioning structure is refined, which may include a positioning block 51 and a positioning groove 52, both of which are also designed on the mating surface. When the installation module 1 is inserted into the host 2 under the action of the guide structure, when the positioning block 51 enters the positioning groove 52, it represents the precise docking of the installation module 1 and the host 2. At this time, the interfaces of the two are also docked, thereby realizing the conduction between the auxiliary installation module 1 and the host 2 and improving the assembly efficiency. As for the positions of the positioning block 51 and the positioning groove 52, they can also be selected according to needs. For example, the positioning block 51 is designed on the host 2, and the positioning groove 52 is designed on the installation module 1, or vice versa. This embodiment does not limit this.

[0031] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The recessed portion b is an open groove with multiple openings, and the protruding portion a has mating surfaces that mate with the bottom and walls of the open groove. In this embodiment, the recessed portion b is an open groove with open sides and top surfaces, thereby forming a stepped structure within the groove. Correspondingly, the protruding portion a also forms a stepped structure. When the two are combined, a complete block structure is formed, and the multiple surfaces of the open groove are also closed by the protruding portion a. Simply put, the protruding portion a can be embedded in the recessed portion b, and the two are used in combination.

[0032] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , the device also includes a magnet assembly for attracting the recessed portion b and the protruding portion a. In this embodiment, in order to facilitate the alignment and detachability of the recessed portion b and the protruding portion a, the magnetism of the magnet assembly can be used to achieve this. Preferably, the magnet assembly includes a first magnet 53 provided on the recessed portion b and a second magnet 54 provided on the protruding portion a, and the first magnet 53 and the second magnet 54 are attracted to each other. The number of the first magnet 53 and the second magnet 54 is not limited here, and there can be four respectively as shown in this embodiment. In addition, in other embodiments, there may be a magnet only on the host 2, and no magnet on the mounting module 1, but an attraction point is designed on the mounting module 1 at the position corresponding to the magnet of the host 2 for the magnet to adsorb, and vice versa. Both implementation methods are possible.

[0033] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4, the device also includes a communication component for conducting between the host 2 and the installation module 1. In this embodiment, the host 2 and the installation module 1 need to be conducted for use, and a communication component can be used to connect the two. Preferably, the communication component includes a first interface 60 provided on the host 2 and a second interface 61 provided on the installation module 1, the first interface 60 is connected to the second interface 61, and the first interface 60 and the second interface 61 are both provided on the mating surface. The communication method can be in the form of an interface docking interface, such as designing a POGO male socket on the host 2 and a POGO female socket on the installation module 1. Of course, the positions of the two can also be swapped. In other embodiments, the interface form may not be adopted, or a signal line may be drawn out from the interface, and the two are connected by a signal line. This is a feasible method.

[0034] See also Figures 5 to 10 The present device includes an anti-retraction locking structure. With the anti-advance and retreat locking structure, it is not necessary to keep pressing the elastic locking component when removing the installation module 1 from the host 2, which facilitates the disassembly of the installation module. Specifically, the anti-retraction locking structure includes two sets of elastic locking components, which are relatively arranged on the host 2. The host 2 is provided with a cavity for accommodating the elastic locking components. The two ends of the installation module 1 are respectively provided with a limit groove 11 corresponding to the lock 31 of the elastic locking component; the elastic locking component includes: a slide 32, which is connected to the lock 31, and a slide hole 22 corresponding to the lock 31 is provided on the host 2. The lock 31 slides through the slide hole 22, and the end thereof extending into the interior of the host 2 is tilted; a spring bracket 33, which is connected to the host 2; a lock spring 34, whose two ends are respectively connected to the slide 32 and the spring bracket 33. The sliding direction of the slide 32 and the expansion and contraction direction of the lock spring 34 are both the same as the direction of the slide hole 22; the lock 31 is a wedge-shaped block, and its end in contact with the installation module 1 is inclined to ensure that the lock 31 can be gradually pushed into the slide hole 22 during the process of inserting the installation module 1 into the host 2. At the same time, after the lock 31 enters the limit groove 11, the lock 31 restricts the installation module 1 when the installation module 1 is pulled out of the host 2.

[0035] See also Figures 5 to 10Two sets of anti-retraction components are linked to two sets of elastic lock components. The anti-retraction components include: a rotating shaft 38, which is mounted on the slide 32; a limiting rod 37 with a limiting block 36; a notch 21 corresponding to the limiting block 36 is provided on the bottom of the slot of the main unit 2; and a first limiting hole 12 corresponding to the limiting block 36 is provided at the end of the installation module 1 near the bottom of the slot of the main unit 2. The limiting rod 37 is rotatably connected to the rotating shaft 38. The limiting rod 37 has a mounting opening at the connection with the rotating shaft 38. A torsion spring 39 is disposed within the mounting opening and sleeved on the rotating shaft 38. The torsion spring 39 is connected to the limiting rod 37 and the slide 32 respectively. Under the force of the torsion spring 39, the limiting rod 37 rotates toward the notch 21, allowing the limiting block 36 to pass through the notch 21 and extend into the first limiting hole 12. Under the action of an external force, after the lock 31 moves out of the corresponding limiting slot 11, the limiting blocks 36 extend into the first limiting holes 12. Furthermore, to prevent the limiting block 36 from exerting a force on the mounting module 1 when the locking buckle 31 is inserted into the limiting groove 11, thereby affecting the connection stability between the mounting module 1 and the mounting groove, a second limiting hole 13 corresponding to the limiting block 36 is provided at one end of the mounting module 1 near the bottom of the groove of the host 2. When the locking buckle 31 is inserted into the limiting groove 11, the limiting block 36 passes through the notch 21 and extends into the second limiting hole 13. Preferably, the host 2 has an opening for the limiting block 36 to extend out of. Specifically, the opening can be provided at the bottom of the groove of the recessed portion b.

[0036] See also Figures 5 to 10 In the above embodiment, when the installation module 1 is not inserted into the host 2, this time is the initial position of the elastic locking component and the anti-retraction component, and the slide 32 moves toward the inside of the host 2 under the action of the locking spring 34 until it conflicts with the host 2. At this time, the lock 31 extends into the host 2. During the movement of the slide 32, the limit rod 37 moves therewith, and the limit block 36 passes through the notch 21 on the bottom of the host 2 groove under the action of the torsion spring 39 and extends into the host 2. Preferably, a lock switch 35 is installed on the slide 32, and the lock switch 35 can move the slide 32. Most of the above-mentioned anti-retraction locking structure 3 is located in the host 2, and only the lock 31, the limit block 36 and the lock switch 35 extend to the surface of the host 2, such as Figure 3 An opening is provided on the host 2 for the lock switch 35 to extend out, so that the lock switch 35 can be pressed by a finger or other component to drive the slide 32.

[0037] See also Figures 5 to 10When the locking clasp 31 is inserted into the main body 2, the two ends of the mounting module 1 begin to conflict with the locking buckle 31, and drive the locking buckle 31 to slide into the sliding hole 22 and compress the locking spring 34. When the limiting groove 11 on the mounting module 1 moves to communicate with the corresponding sliding hole 22, the sliding of the locking clasp 31 is no longer restricted by the mounting module 1, and under the action of the locking spring 34, the locking clasp 31 slides into the limiting groove 11. At this time, the locking clasp 31 can limit the mounting module 1 in the first direction; during the sliding process of the slide 32, the limiting rod 37 is driven to move together, and the mounting module 1 will contact the limiting block 36 when it approaches the bottom of the groove of the main body 2. The limiting rod 37 rotates relative to the slide 32 without affecting the movement of the mounting module 1. When the locking clasp 31 slides into the limiting groove 11, the limiting block 36 on the limiting rod 37 slides into the first limiting hole 12 on the mounting module 1, and the limiting block 36 limits the mounting module 1 in the second direction.

[0038] See also Figures 5 to 10 When the installation module 1 needs to be pulled out of the main unit 2, a force is first applied to the slide 32 to move it away from the main unit 2 and drive the lock 31 to move completely into the slide hole 22. At this time, the limit rod 37 moves together, and the limit block 36 on the limit rod 37 leaves the first limit hole 12 and slides into the second limit hole 13. At this time, the installation module 1 limits the limit block 36 in the second direction, that is, it limits the sliding of the slide 32 in the second direction. Therefore, after the external force on the slide 32 is removed, the lock spring 34 applies force to the slide 32, and the slide 32 remains stationary. In this way, the installation module 1 can be removed from the main unit 2 without continuously applying force to the slide 32. After the installation module 1 is removed, the limit of the limit block 36 by the installation module 1 in the second direction is released, and the elastic lock assembly and the anti-retraction assembly return to their initial positions.

[0039] See also Figures 5 to 10 As another embodiment of the present invention, the anti-retraction component also includes a stopper 23, which is connected to the main unit 2. When the limit block 36 extends into the first limit hole 12 or the second limit hole 13, the limit rod 37 conflicts with the stopper 23.

[0040] See also Figures 5 to 10 A protrusion can be set at the lower end of the host 2, and a stopper 23 can be formed by the protrusion. The stopper 23 can keep the limiting rod 37 parallel to the sliding direction of the lock 31.

[0041] As another embodiment of the present invention, please refer to Figures 5 to 10 A lock switch 35 is provided on the slide 32 .

[0042] When the anti-retraction locking structure is applied, a strip through hole corresponding to the lock switch 31 is generally set on the host 2. The lock switch 31 is slidably set in the strip through hole. The movement of the slide 32 and the lock 31 can be achieved by simply pushing the lock switch 31 by hand.

[0043] See also Figures 5 to 10 The fixed-focus infrared lens module 62 or the zoom infrared lens module 63 of the imaging device constitutes the mounting module 1. In the above embodiment, the anti-retraction locking structure is applied to the imaging device. The host 2 is, for example, an audio and video camera. A mounting interface or a through-hole for the wiring harness to pass through is provided on the bottom of the groove of the host 2. The fixed-focus infrared lens module 62 and the zoom infrared lens module 63 matched with the audio and video camera adopt the structure of the mounting module 1, so that the fixed-focus infrared lens module 62 or the zoom infrared lens module 63 can be quickly connected to the audio and video camera. In addition, when replacing the fixed-focus infrared lens module 62 or the zoom infrared lens module 63, there is no need to press the elastic locking assembly by hand, which makes the operation more convenient.

[0044] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
