Description

Technical Field

[0001] The utility model relates to the field of camera installation, in particular to a camera device. Background Art

[0002] The camera includes a mounting bracket, a lens mount and a lens. The lens is mounted on the lens mount. The lens mount needs to be mounted on a wall, ceiling, etc. through the mounting bracket. In order to simplify the assembly between the mounting bracket and the lens mount, the mounting bracket and the lens mount are connected by a buckle. However, the connection stability of the buckle is limited. When the lens mount is subjected to a large impact, the buckle will be detached from the slot, causing the lens mount to fall off the mounting bracket. Therefore, the stability of the existing camera after being subjected to an impact is insufficient. Utility Model Content

[0003] Based on this, it is necessary to provide a camera device to address the problem of insufficient stability of the camera after being impacted.

[0004] A camera device comprises a mounting bracket and a lens mount;

[0005] The mounting bracket includes a first body, an elastic arm and a guide portion, wherein the guide portion is arranged on the first body, the elastic arm includes a first limiting protrusion, a first elastic section and a second elastic section, two ends of the first elastic section are elastically connected to the guide portion and the second elastic section respectively, and the first limiting protrusion is arranged on the second elastic section;

[0006] The lens mount is provided with a first assembly groove and a second assembly groove, and a limit plate is provided on the lens mount;

[0007] The guide portion is slidably disposed at the first assembly groove, the first limiting protrusion is at least partially located in the second assembly groove, and the limiting plate is used to limit the deformation of the first elastic section.

[0008] The utility model has two guide parts, namely a first guide plate and a second guide plate. The first assembly groove has a first guide surface and a second guide surface. The second guide plate is attached to the first guide surface, and the first guide plate is attached to the second guide surface.

[0009] The mounting bracket of the utility model further comprises a first supporting plate and a second supporting plate, the first assembly slot further comprises a first supporting surface, and the first supporting plate and the second supporting plate are both attached to the first supporting surface.

[0010] According to the utility model, the first assembly groove also has a first limiting surface, and at least one of the first guide plate, the second guide plate, the first support plate and the second support plate abuts against the first limiting surface axially along the first assembly groove, and the second assembly groove has a second limiting surface, and the first limiting protrusion abuts against the second limiting surface axially along the first assembly groove.

[0011] In the utility model, a first connecting rod and a first pressing block are arranged in the first assembly groove, the first pressing block is fixed to one end of the first connecting rod, the other end of the first connecting rod is fixed to the first supporting surface, a part of the first supporting plate and a part of the second supporting plate are clamped between the first pressing block and the first supporting surface, so that the mounting bracket is positioned on the lens mount.

[0012] In the utility model, a first avoidance gap is formed on the first support plate, and a second avoidance gap is formed on the second support plate. The edge of the first avoidance gap and the edge of the second avoidance gap are both in contact with the outer wall of the first connecting rod.

[0013] In the utility model, the first support plate and the second support plate are spaced apart to form a wiring opening between the first support plate and the second support plate, and a part of the wiring opening is located outside the first assembly groove.

[0014] A part of the second elastic section of the utility model is fitted to the lens holder so that the first limiting protrusion is located in the second assembly groove.

[0015] The second elastic section of the utility model is provided with an operating hole, and the operating hole is located outside the second assembly groove and at least partially exposed to the lens seat.

[0016] The first elastic section of the utility model is fitted on the lens holder.

[0017] The beneficial effects of the utility model are:

[0018] The first elastic section and the second elastic section cooperate to deform to allow the guide part to slide into the first assembly groove. During this process, the first elastic section can avoid the limit plate and the lens mount, and the first limit protrusion can avoid the lens mount. When the guide part is assembled in place, the elastic arm is released, and the first elastic section and the second elastic section are restored to allow the first limit protrusion to enter the second assembly groove, completing the installation of the mounting bracket on the lens mount.

[0019] When the lens mount is impacted, the first elastic section and the second elastic section will deform. Since the deformation of the first elastic section is limited by the limiting plate, as long as the impact force is within a certain limit, it is often difficult to cause the first limiting protrusion to produce sufficient displacement relying solely on the deformation of the second elastic section. The first limiting protrusion cannot be detached from the second assembly groove, thereby ensuring the assembly stability between the mounting bracket and the lens mount.

[0037] Example:

[0038] See also Figure 1 A camera device includes a mounting bracket 1, a lens mount 2 and a camera 3, wherein the camera 3 is mounted at the bottom of the lens mount 2 and the mounting bracket 1 is mounted at the top side edge of the lens mount 2. In this embodiment, the first direction, the second direction and the third direction are perpendicular to each other.

[0039] See also Figure 2-Figure 5 The mounting bracket 1 includes a first body 11, an elastic arm 12 and a guide portion.

[0040] In this embodiment, there are two guide parts, namely, a first guide plate 13 and a second guide plate 14, which are both fixed to the first body 11. As an example, in this embodiment, the first guide plate 13 and the second guide plate 14 are opposite and spaced apart in the first direction.

[0041] In this embodiment, the elastic arm 12 is located on the side of the second guide plate 14 away from the first guide plate 13. The elastic arm 12 includes a first limiting protrusion 121, a first elastic section 122, and a second elastic section 123. The first elastic section 122 is located between the second guide plate 14 and the second elastic section 123, and the two ends of the first elastic section 122 are elastically connected to the second guide plate 14 and one end of the second elastic section 123, respectively, and the first limiting protrusion 121 is arranged on the second elastic section 123. In this embodiment, the first elastic section 122 and the second elastic section 123 are both sheet-shaped and perpendicular to the third direction, and the first limiting protrusion 121 is located on the lower surface of the second elastic section 123.

[0042] See also Figure 6 and Figure 7 The lens mount 2 is provided with a first assembly groove 21 and a second assembly groove 22, and the first assembly groove 21 and the second assembly groove 22 are arranged in sequence in the first direction. In addition, a limit plate 23 is provided on the lens mount 2. The first assembly groove 21 has a first guide surface 211 and a second guide surface 212. Preferably, the first guide surface 211 and the second guide surface 212 are parallel and opposite to each other in the first direction. The first assembly groove 21 penetrates to the outer wall of the lens mount 2 along the second direction, so that the guide part (the first guide plate 13 and the second guide plate 14) can enter and exit the first assembly groove 21 along the second direction. The second assembly groove 22 penetrates to the outer wall of the lens mount 2 along the third direction.

[0043] See also Figure 8 and Fig. 9 , the distance between the first guide plate 13 and the second guide plate 14 matches the distance between the first guide surface 211 and the second guide surface 212, and the axial direction of the first assembly groove 21 is parallel to the second direction. Therefore, when the first guide plate 13 and the second guide plate 14 enter the first assembly groove 21 along the second direction, the second guide plate 14 is attached to the first guide surface 211, and the first guide plate 13 is attached to the second guide surface 212. Therefore, as long as the first guide plate 13 and the second guide plate 14 enter the first assembly groove 21, the mounting bracket 1 can be positioned on the lens holder 2 at least in the first direction.

[0044] When the first guide plate 13 and the second guide plate 14 enter the first assembly groove 21 along the second direction, the first elastic section 122 needs to bend and deform to avoid the limiting plate 23 and the lens holder 2. The second elastic section 123 also needs to deform. The deformation of the first elastic section 122 and the deformation of the second elastic section 123 are superimposed, so that the first limiting protrusion 121 generates sufficient displacement in the third direction, thereby avoiding the lens holder 2. When the first guide plate 13 and the second guide plate 14 are assembled in place in the first assembly groove 21, the projection of the first limiting protrusion 121 in the third direction falls within the second assembly groove 22, and the first limiting protrusion 121 is located outside the second assembly groove 22. At this time, the first limiting protrusion 121 is in an avoiding state. Then, as long as the bending of the first elastic section 122 and the second elastic section 123 is stopped, the first elastic section 122 and the second elastic section 123 are restored, and the first limiting protrusion 121 can be reset along the third direction and at least partially enter the second assembly groove 22, and the first limiting protrusion 121 is converted from the avoidance state to the limiting state. When the first limiting protrusion 121 is in the limiting state, the movement of the first limiting protrusion 121 in the second direction is limited by the side wall of the second assembly groove 22, so the mounting bracket 1 cannot be directly detached from the lens holder 2 by moving in the second direction.

[0045] When the first limiting protrusion 121 is in the limiting state, the limiting plate 23 is located on the side of the first elastic section 122 away from the first limiting protrusion 121, and the projection of the limiting plate 23 in the third direction at least partially falls on the first elastic section 122, so that the limiting plate 23 has the function of limiting the deformation of the first elastic section 122. If the lens holder 2 is impacted when the first limiting protrusion 121 is in the limiting state, the first elastic section 122 and the second elastic section 123 will be deformed, thereby causing the first limiting protrusion 121 to be displaced in the third direction. The displacement of the first limiting protrusion 121 is obtained by superimposing the deformation of the first elastic section 122 and the second elastic section 123. Since the deformation of the first elastic section 122 is limited by the limiting plate 23, as long as the impact force on the lens holder 2 is not very large, the first limiting protrusion 121 cannot generate enough displacement in the third direction, and cannot be separated from the second assembly groove 22. Therefore, compared with the prior art, the connection stability between the lens holder 2 and the mounting bracket 1 is improved when subjected to impact.

[0046] On the other hand, if the first limiting protrusion 121 needs to be converted from the limiting state to the avoiding state, in the process of prying the elastic arm 12, not only the first elastic section 122 needs to be deformed, but also the second elastic section 123 needs to be sufficiently deformed, so that the first limiting protrusion 121 can generate a sufficient displacement in the third direction and then be separated from the second assembly groove 22. After the first limiting protrusion 121 is switched to the avoiding state, the mounting bracket 1 can be removed from the lens holder 2 by moving the mounting bracket 1 along the second direction.

[0047] See also Figure 2-Figure 5 The mounting bracket 1 also includes a first support plate 15 and a second support plate 16, both of which are perpendicular to the third direction, the first support plate 15 is fixed on the first guide plate 13, the second support plate 16 is fixed on the second guide plate 14, and the first support plate 15 and the second support plate 16 are located between the first guide plate 13 and the second guide plate 14.

[0048] The first support plate 15 can increase the mechanical strength of the first guide plate 13, and the second support plate 16 can increase the mechanical strength of the second guide plate 14. Figure 6-Figure 8 The first assembly groove 21 also has a first supporting surface 213, which is perpendicular to the third direction and is located between the first guide surface 211 and the second guide surface 212. Therefore, when the first guide plate 13 and the second guide plate 14 enter the first assembly groove 21, the first supporting plate 15 and the second supporting plate 16 can both maintain a fit with the first supporting surface 213, thereby increasing the contact area between the mounting bracket 1 and the lens mount 2 and improving the connection stability between the mounting bracket 1 and the lens mount 2.

[0049] See also Figure 3 The first support plate 15 and the second support plate 16 are spaced apart in the first direction to form a wiring opening 17 between the first support plate 15 and the second support plate 16. After the first support plate 15 and the second support plate 16 are assembled in place at the first assembly groove 21, a portion of the wiring opening 17 is located outside the first assembly groove 21 for the camera 3 to route the wiring.

[0050] See also Figure 6-Figure 9A first connecting rod 215 and a first pressing block 216 are arranged in the first assembly groove 21. The first connecting rod 215 extends along the third direction. The lower end of the first connecting rod 215 is fixed on the first supporting surface 213. The first pressing block 216 is fixed on the upper end of the first connecting rod 215, so that the first pressing block 216 and the first supporting surface 213 are arranged at intervals. The partial projection of the first pressing block 216 in the third direction is located outside the partial projection of the first connecting rod 215 in the third direction. Therefore, when the first support plate 15 and the second support plate 16 move into the first assembly groove 21 along the second direction, a part of the first support plate 15 and a part of the second support plate 16 can enter the gap between the first pressing block 216 and the first supporting surface 213, and the first support plate 15 and the second support plate 16 are clamped by the first pressing block 216 and the first supporting surface 213. Accordingly, when the first guide plate 13 and the second guide plate 14 are assembled in place, the mounting bracket 1 is also positioned on the lens holder 2 in the third direction.

[0051] See also Figure 6-Figure 8 The first assembly groove 21 also has a first limiting surface 214, and the first limiting surface 214 is located between the first guide surface 211 and the second guide surface 212. In this embodiment, the first limiting surface 214 is perpendicular to the second direction. The second assembly groove 22 has a second limiting surface 221, and the second limiting surface 221 can be a plane or an arc surface. When the first limiting protrusion 121 is in a limiting state, at least one of the first guide plate 13, the second guide plate 14, the first support plate 15 and the second support plate 16 abuts against the first limiting surface 214 along the second direction, so that the first guide plate 13 and the second guide plate 14 cannot further enter the first assembly groove 21 along the second direction. At the same time, the first limiting protrusion 121 abuts against the second limiting surface 221 along the second direction, and the first limiting protrusion 121 cannot retreat along the second direction. Therefore, when the first limiting protrusion 121 is in the limiting state, with the cooperation of the first limiting surface 214 and the second limiting surface 221 , the mounting bracket 1 can be positioned in the second direction on the lens holder 2 .

[0052] It can be seen that, in the camera device of this embodiment, only by bending the first elastic section 122 and the second elastic section 123 first, so that the first limit protrusion 121 obtains the freedom to move in the second direction, and then moving the mounting bracket 1 or the lens holder 2 in the second direction, can the mounting bracket 1 and the lens holder 2 be disassembled and assembled. The above disassembly and assembly method does not need to involve screw disassembly and assembly, which greatly increases the disassembly and assembly efficiency between the mounting bracket 1 and the lens holder 2.

[0053] See also Figure 3-Figure 5A first avoidance gap 151 is provided on the first support plate 15, and a second avoidance gap 161 is provided on the second support plate 16. The shapes of the first avoidance gap 151 and the second avoidance gap 161 match the outer wall shape of the first connecting rod 215, for example, they are arc-shaped, so that the edge of the first avoidance gap 151 and the edge of the second avoidance gap 161 can fit with the outer wall of the first connecting rod 215 to increase the connection stability between the mounting bracket 1 and the lens holder 2.

[0054] Also, in order to increase the connection stability between the mounting bracket 1 and the lens mount 2, see Fig. 9 When the first limiting protrusion 121 is in the limiting state, the first elastic section 122 is attached to the lens mount 2 , and a portion of the second elastic section 123 is also attached to the lens mount 2 , so as to allow the first limiting protrusion 121 to be completely located in the second assembly groove 22 .

[0055] See also Figure 3 and Figure 5 In this embodiment, an operation hole 124 is provided at the end of the second elastic section 123 away from the first elastic section 122. Fig. 9 When the first limiting protrusion 121 is in the limiting state, the operating hole 124 is located outside the second assembly groove 22, and the operating hole 124 is not completely blocked by the lens holder 2. The operating hole 124 is partially exposed from the lens holder 2. The disassembly and assembly personnel can pry the second elastic section 123 at the operating hole 124 with their fingers, and use the lever principle to control the bending deformation of the second elastic section 123 with a smaller force, which makes it more convenient to switch the first limiting protrusion 121 from the limiting state to the avoidance state.

[0056] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
