Description

Technical Field

[0001] This utility model relates to the field of surveillance equipment technology, and in particular to a camera. Background Technology

[0002] In the installation process of existing cameras, the base is usually installed on a mounting surface such as a wall or ceiling first, and then the camera and housing are installed on the base together using fasteners such as screws and bolts.

[0003] However, because the camera is prone to falling out of the housing during installation, users need to hold the camera and housing together while securing the fasteners, making the operation difficult and inconvenient for users to disassemble and assemble the camera. Utility Model Content

[0004] Therefore, it is necessary to provide a camera that addresses the above issues, making it easier for users to install and remove the camera.

[0005] This utility model provides a camera, comprising: a mounting base; a housing assembly detachably disposed on the mounting base, the housing assembly including a cover and at least two limiting members, the cover including a mounting cavity and a mounting opening communicating with the mounting cavity, and each of the limiting members being detachably disposed on the inner wall of the mounting opening along the circumference of the mounting opening; and a camera detachably disposed within the mounting cavity; wherein the cross-sectional area of ​​the limiting region formed by each of the limiting members and the inner wall of the mounting opening is smaller than the maximum cross-sectional area of ​​the camera.

[0006] In the aforementioned camera, during installation, the camera is first placed into the mounting cavity, and then the limiting component is fixed to the inner wall of the mounting opening. At this time, the cross-sectional area of ​​the limiting area formed by the limiting component and the inner wall of the mounting opening is smaller than the maximum cross-sectional area of ​​the camera, thereby preventing the camera from accidentally detaching from the mounting opening, so that the camera and the housing assembly form an integral module. Finally, the integral module is installed on the mounting base to complete the assembly. Disassembly is performed in the reverse order. Users do not need to provide additional support for the camera and housing assembly during the assembly and disassembly process, thereby reducing the difficulty of operation and making it easier for users to assemble and disassemble the camera.

[0007] In one embodiment, the mounting base includes a base and an annular snap-fit ​​portion disposed on the base, and the limiting member includes a first snap-fit ​​portion, which is capable of engaging with the annular snap-fit ​​portion and sliding along the circumference of the annular snap-fit ​​portion.

[0008] This design allows for angle adjustment without disassembling the housing components and camera, reducing the risk of the housing components and camera falling or being lost. The adjustment process is also simple, convenient, safe, and efficient.

[0009] In one embodiment, the camera further includes a fastener disposed on the housing, the fastener having a locked state and an unlocked state; in the locked state, the fastener cooperates with the mounting base to restrict the first snap-fit ​​portion from sliding circumferentially along the annular snap-fit ​​portion; in the unlocked state, the fastener is separated from the mounting base.

[0010] This configuration improves the overall stability and reliability of the camera when the fasteners are locked, preventing the housing components and camera from accidentally falling off. It also prevents the housing components from accidentally rotating relative to the mounting base, which could affect the camera's shooting performance.

[0011] In one embodiment, the cover is provided with a threaded hole, and the fastener includes a threaded portion and a locking portion connected to each other, the threaded portion and the threaded hole being threadedly engaged; the annular snap-fit ​​portion is provided with a first snap-fit ​​surface on the side opposite to the cover, the first snap-fit ​​surface is inclined from the inside out toward the side closer to the cover, and in the locked state, the locking portion abuts against the first snap-fit ​​surface.

[0012] This design ensures the stability and reliability of the connection between the fastener and the cover, and the fastener will not fall off in the unlocked state. During the locking process, the locking part will abut against the first snap-fit ​​surface and apply a force towards the base to press and fix the cover and the base together, thereby limiting the rotation of the housing assembly relative to the mounting base.

[0013] In one embodiment, the mounting base further includes an elastic abutment disposed on the base. In the unlocked state, the camera is separated from the elastic abutment, and in the locked state, the camera abuts against the elastic abutment.

[0014] This design allows the elastic abutment to improve the stability and reliability of the camera during use, prevent the camera from rotating unexpectedly relative to the housing and mounting base, and also reduce impact loads, protect the camera, and reduce image jitter.

[0015] In one embodiment, the first snap-fit ​​portion is an elastic element.

[0016] With this design, the first locking part can engage with the ring-shaped locking part under its own elastic force, thus allowing the user to operate with one hand.

[0017] In one embodiment, the limiting member further includes a limiting part, which is connected to the first snap-fit ​​part in an L-shape. The inner wall of the cover is provided with a fixing part, and the limiting part is detachably disposed on the fixing part and forms the limiting area with the inner wall of the mounting port.

[0018] With this design, the limiting component can simultaneously connect to the mounting base and limit the camera position, thereby reducing the number of parts and simplifying the structure for easier production and assembly.

[0019] In one embodiment, the limiting part is integrally formed with the first snap-fit ​​part; and / or, the limiting part is a plastic part or a sheet metal part.

[0020] This setup is to facilitate production assembly.

[0021] In one embodiment, the first snap-fit ​​portion is provided with a guide surface on the side facing the base and / or the annular snap-fit ​​portion is provided with a guide surface that is inclined from the inside out toward the side closer to the base.

[0022] With this configuration, during installation, the first snap-fit ​​part and the annular snap-fit ​​part can slide together through the guide surface, causing the first snap-fit ​​part to automatically deform towards the side away from the annular snap-fit ​​part, making it easier for the user to operate.

[0023] In one embodiment, the mounting base includes a base and an annular snap-fit ​​portion disposed on the base, and the housing assembly further includes a second snap-fit ​​portion disposed on the inner wall of the mounting opening, the second snap-fit ​​portion being capable of engaging with the annular snap-fit ​​portion and sliding along the circumference of the annular snap-fit ​​portion.

[0024] This design improves the stability and reliability of the connection between the housing assembly and the mounting base. Attached Figure Description

[0037] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0039] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0041] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0042] In existing camera installation processes, the base is typically installed onto a wall or ceiling first, and then the camera and housing are attached to the base using screws, bolts, and other fasteners. However, because the camera can easily detach from the housing during installation, users need to hold both the camera and housing while simultaneously securing the fasteners, making the process difficult and inconvenient for users to install and remove the camera.

[0043] To solve the above problems, such as Figures 1 to 10 As shown, this utility model provides a camera to facilitate user assembly and disassembly of the camera.

[0044] like Figures 1 to 2As shown, specifically, the camera includes a mounting base 1, a housing assembly 2, and a camera 3. The housing assembly 2 is detachably mounted on the mounting base 1. The housing assembly 2 includes a cover 21 and at least two limiting members 22. The cover 21 includes a mounting cavity 211 and a mounting opening 212 communicating with the mounting cavity 211. Along the circumference of the mounting opening 212, each limiting member 22 is detachably mounted on the inner wall of the mounting opening 212. The camera 3 is detachably mounted inside the mounting cavity 211. The cross-sectional area of ​​the limiting region a formed by each limiting member 22 and the inner wall of the mounting opening 212 is smaller than the maximum cross-sectional area of ​​the camera 3.

[0045] In the camera provided in this embodiment of the utility model, the mounting base 1 can be fixed to an external mounting surface such as a wall, ceiling, or suspended ceiling by means of screws, bolts, or clips. During installation, the camera 3 is first placed into the mounting cavity 211, and then the limiting member 22 is fixed to the inner wall of the mounting opening 212. At this time, the cross-sectional area of ​​the limiting area a formed by the limiting member 22 and the inner wall of the mounting opening 212 is smaller than the maximum cross-sectional area of ​​the camera 3, thereby preventing the camera 3 from accidentally coming out of the mounting opening 212, so that the camera 3 and the housing assembly 2 form an integral module. Finally, the integral module is installed on the mounting base 1 to complete the assembly. During disassembly, the operation is carried out in the reverse order. In this way, the user does not need to support the camera 3 and the housing assembly 2 during the disassembly and assembly process, thereby reducing the difficulty of operation and making it easier for the user to disassemble and assemble the camera.

[0046] like Figure 1 and Figure 8 As shown, in one embodiment, the end of the cover 21 facing away from the mounting opening 212 is provided with a shooting opening 215 communicating with the mounting cavity 211. The camera 3 faces the shooting opening 215, or part of the camera 3 is exposed outside the shooting opening 215, to avoid the cover 21 obstructing the camera 3 and to ensure that the camera 3 can shoot normally. Of course, in other embodiments, the cover 21 may also include a light-transmitting part, with the camera 3 facing the light-transmitting part to ensure that the camera 3 can shoot normally.

[0047] like Figure 1 , Figure 2 and Figure 8As shown, in one embodiment, the mounting base 1 includes a base 11 and an annular snap-fit ​​portion 12 disposed on the base 11. The limiting member 22 includes a first snap-fit ​​portion 221, which can engage with the annular snap-fit ​​portion 12 and slide along the circumference of the annular snap-fit ​​portion 12. When the first snap-fit ​​portion 221 engages with the annular snap-fit ​​portion 12, the housing assembly 2 and the camera 3 will not fall off the mounting base 1 and can rotate relative to the mounting base 1. This allows for angle adjustment without disassembling the housing assembly 2 and the camera 3, making it less likely for the housing assembly 2 and the camera 3 to fall off or be lost. Furthermore, the adjustment process is simple and convenient, and the operation is safer and more efficient. Of course, in other embodiments, the user can also adjust the angle of the housing assembly 2 and the camera 3 and then directly fix the housing assembly 2 to the mounting base 1 using screws, bolts, or clips, as long as the stability and reliability of the connection between the housing assembly 2 and the mounting base 1 can be ensured. This embodiment of the present invention does not impose specific limitations here.

[0048] like Figures 2 to 4 As shown, in one embodiment, the first snap-fit ​​portion 221 is an elastic element. During installation, the first snap-fit ​​portion 221 can first deform towards the side away from the annular snap-fit ​​portion 12, and after being installed in place, it automatically resets under its own elastic force and engages with the annular snap-fit ​​portion 12, thereby allowing the user to operate with one hand.

[0049] Specifically, the limiting member 22 also includes a limiting part 222, which is connected to the first snap-fit ​​part 221 in an L-shape. The inner wall of the cover 21 is provided with a fixing part 213. The limiting part 222 is detachably disposed on the fixing part 213 and forms a limiting area a with the inner wall of the mounting opening 212. Thus, the limiting member 22 can simultaneously connect to the mounting base 1 and limit the camera 3, thereby reducing the number of parts and simplifying the structure for easier production and assembly. The limiting part 222 can be fixedly connected to the fixing part 213 by screws, bolts, or clips to ensure the stability and reliability of the connection between the limiting member 22 and the cover 21. One limiting part 222 can be connected to one, two, three, or more first snap-fit ​​parts 221, with each first snap-fit ​​part 221 arranged circumferentially at intervals along the annular snap-fit ​​part 12. Alternatively, a first snap-fit ​​portion 221 may be connected to two, three or more limiting portions 222, with each limiting portion 222 arranged at circumferential intervals along the mounting opening 212.

[0050] The limiting part 222 and the first engaging part 221 can be integrally formed to ensure the overall reliability of the limiting part 22 and facilitate production and assembly; alternatively, the limiting part 222 and the first engaging part 221 can be processed separately and fixed by means of adhesive, screws, bolts, buckles, etc. The limiting part 22 can be a plastic part and processed by injection molding or other methods; alternatively, the limiting part 22 can also be a sheet metal part or other metal material and processed by cutting, bending, etc.

[0051] like Figure 3 and Figure 8 As shown, at least one of the first latching portion 221 facing the base 11 and the annular latching portion 12 facing the cover 21 is provided with a guide surface 2211. The guide surface 2211 is inclined from the inside out towards the side closer to the base 11. During installation, when pressure is applied to the housing assembly 2 towards the base 11, the first latching portion 221 and the annular latching portion 12 can slide and engage through the guide surface 2211, causing the first latching portion 221 to automatically deform towards the side away from the annular latching portion 12, thereby making it easier for the user to operate.

[0052] like Figure 3 , Figure 7 and Figure 8 As shown, the annular snap-fit ​​portion 12 has a first snap-fit ​​surface 121 on the side opposite to the cover 21, and the first snap-fit ​​portion 221 has a second snap-fit ​​surface 2212 on the side opposite to the base 11, which can snap into the first snap-fit ​​surface 121. The first snap-fit ​​surface 121 and the second snap-fit ​​surface 2212 can be inclined surfaces, tilting from the inside out towards the side closer to the cover 21. During disassembly, applying a pulling force away from the base 11 to the housing assembly 2 allows the first snap-fit ​​portion 221 and the annular snap-fit ​​portion 12 to slide into each other via the first snap-fit ​​surface 121 and the second snap-fit ​​surface 2212, causing the first snap-fit ​​portion 221 to automatically deform towards the side away from the annular snap-fit ​​portion 12, thus facilitating user operation. Alternatively, the first snap-fit ​​surface 121 and the second snap-fit ​​surface 2212 can also be parallel to the plane of the base 11 to improve the stability and reliability of the snap-fit ​​engagement between the first snap-fit ​​portion 221 and the annular snap-fit ​​portion 12.

[0053] like Figure 3 As shown, in the illustrated embodiment, the first engaging portion 221 includes a protrusion with a triangular or trapezoidal cross-section, and the two inclined surfaces of the triangle or trapezoid are the second engaging surface 2212 and the guide surface 2211, respectively. Figure 4 As shown in the illustrated embodiment, the first snap-fit ​​portion 221 includes an arc-shaped protrusion, and the outer surface of the arc-shaped protrusion forms a second snap-fit ​​surface 2212 and a guide surface 2211.

[0054] Of course, in other embodiments, the first engaging portion 221 can also be telescopically, rotatably, or slidably disposed on the inner wall of the mounting opening 212. During installation, the first engaging portion 221 can first move towards the side away from the annular engaging portion 12, and after being installed in place, it can move towards the side closer to the annular engaging portion 12 and engage with it. Furthermore, the limiting portion 222 and the first engaging portion 221 can also be separate structures and are fixedly connected to the inner wall of the mounting opening 212 by means of screws, bolts, buckles, etc.

[0055] like Figure 2 , Figure 5 and Figure 6 As shown, in one embodiment, the housing assembly 2 further includes a second engaging portion 23 disposed on the inner wall of the mounting opening 212. The second engaging portion 23 can engage with the annular engaging portion 12 and slide circumferentially along the annular engaging portion 12. The number of second engaging portions 23 can be one, two, or more, and multiple second engaging portions 23 are arranged at intervals along the circumferential direction of the mounting opening 212. Thus, the first engaging portion 221 and the second engaging portion 23 form a double engaging structure, which can improve the stability and reliability of the connection between the housing assembly 2 and the mounting base 1, prevent the housing assembly 2 from tilting relative to the mounting base 1 and affecting the shooting effect of the camera 3, and also prevent the first engaging portion 221 from accidentally disengaging from the annular engaging portion 12, causing the housing assembly 2 and the camera 3 to fall off and be damaged.

[0056] The second locking part 23 can be a rigid structure, and the second locking part 23 and the first locking part 221 are preferably arranged opposite each other on both sides of the mounting opening 212. During installation, the second locking part 23 is first engaged with the annular locking part 12, and then the first locking part 221 is engaged with the annular locking part 12. Alternatively, the second locking part 23 can also be an elastic element. The second locking part 23 and the first locking part 221 are arranged circumferentially around the mounting opening 212. During installation, the second locking part 23 can first deform towards the side away from the annular locking part 12, and after being installed in place, it automatically resets under its own elastic force and engages with the annular locking part 12.

[0057] Furthermore, the second latching portion 23 has a third latching surface 231 on the side opposite to the base 11, which can engage with the first latching surface 121. When the first latching surface 121 is inclined, the third latching surface 231 can also be inclined to increase the contact area between the first latching surface 121 and the third latching surface 231, and at the same time facilitate the second latching portion 23 to be latched into the annular latching portion 12.

[0058] Of course, in other embodiments, the housing assembly 2 may not have the second snap-fit ​​portion 23, and the housing assembly 2 and the mounting base 1 may engage only through the first snap-fit ​​portion 221 and the annular snap-fit ​​portion 12; or, the limiting member 22 may not include the first snap-fit ​​portion 221, and the housing assembly 2 and the mounting base 1 may engage only through the second snap-fit ​​portion 23 and the annular snap-fit ​​portion 12.

[0059] like Figure 1 and Figure 6 As shown, the camera also includes a fastener 4 disposed on the housing 21. The fastener 4 has a locked state and an unlocked state. In the locked state, the fastener 4 cooperates with the mounting base 1 to restrict the first latching part 221 and the second latching part 23 from sliding circumferentially along the annular latching part 12. In the unlocked state, the fastener 4 is separated from the mounting base 1. In the unlocked state, the housing assembly 2 and the camera 3 can be rotated relative to the mounting base 1 to adjust the angle. After adjustment, the fastener 4 is adjusted to the locked state to improve the overall stability and reliability of the camera, prevent the housing assembly 2 and the camera 3 from accidentally falling off, and also prevent the housing assembly 2 from accidentally rotating relative to the mounting base 1, which would affect the shooting effect of the camera 3.

[0060] like Figures 6 to 10 As shown, in one embodiment, the cover 21 is provided with a threaded hole 214, and the fastener 4 includes a threaded portion 41 and a locking portion 42 connected to each other. The threaded portion 41 and the threaded hole 214 are threadedly engaged. The first engaging surface 121 is inclined from the inside out towards the side closer to the cover 21. In the locked state, the locking portion 42 abuts against the first engaging surface 121. The fastener 4 can be a screw, bolt, etc. The threaded connection between the threaded portion 41 and the threaded hole 214 ensures the stability and reliability of the connection between the fastener 4 and the cover 21, and the fastener 4 will not fall off in the unlocked state, preventing parts loss and making operation safer and more efficient. The inclined arrangement of the first engaging surface 121 allows the locking portion 42 to abut against the first engaging surface 121 and apply a force towards the base 11 to the cover 21 during the locking process, thereby pressing and fixing the cover 21 and the base 11, thus restricting the rotation of the housing assembly 2 relative to the mounting base 1. Thus, the adjustment of the fastener 4 is simple and convenient for user operation.

[0061] In the illustrated embodiment, the second snap-fit ​​portion 23 and the fastener 4 are arranged opposite each other on both sides of the cover 21. There are two limiting members 22, which are arranged close to the fastener 4 and respectively on both sides of the fastener 4. Of course, the number and position of the limiting members 22, the second snap-fit ​​portion 23, and the fastener 4 can be adjusted according to actual installation needs, as long as it ensures that the various structures do not interfere with each other. This embodiment of the present invention does not impose specific limitations here.

[0062] Furthermore, the locking part 42 can be a tapered structure that can mate with the first engaging surface 121, thereby increasing the contact area between the locking part 42 and the first engaging surface 121 and improving locking reliability. Additionally, the extension direction of the threaded hole 214 can be inclined from the inside out towards the side away from the base 11, so that during the process of the fastener 4 pressing and fixing the cover 21 and the base 11, the inclination angle of the locking part 42 is as compatible as possible with the first engaging surface 121; of course, the extension direction of the threaded hole 214 can also be parallel to the plane of the base 11.

[0063] Of course, in other embodiments, fastener 4 and cover 21, and fastener 4 and base 11 can also be fixed by other methods such as plugging or snapping, as long as the mounting base 1, housing assembly 2 and fastener 4 can be reliably fixed in the locked state. This utility model embodiment does not make specific limitations here.

[0064] like Figure 8 and Figure 10 As shown, the mounting base 1 also includes an elastic abutment 13 disposed on the base 11. In the unlocked state, the camera 3 is separated from the elastic abutment 13; in the locked state, the camera 3 abuts against the elastic abutment 13. The elastic abutment 13 can be a silicone or rubber component. When the fastener 4 presses the housing 21 and the base 11 together, the camera 3 can compress the elastic abutment 13, improving the stability and reliability of the camera 3 during use and preventing accidental rotation of the camera 3 relative to the housing 21 and mounting base 1. Simultaneously, the elastic abutment 13 can reduce impact load, protect the camera 3, and reduce image jitter. In the unlocked state, the camera 3 is separated from the elastic abutment 13 to reduce friction, allowing the user to control the smooth rotation of the housing assembly 2 and the camera 3 relative to the mounting base 1. Of course, during use, the camera 3 can also be tilted and rotated horizontally within a certain range relative to the housing 21 and mounting base 1 as needed, as long as the housing 21 does not obstruct the camera 3.

[0065] In the illustrated embodiment, during installation, as follows: Figures 6 to 8 As shown, first, the second latching part 23 is engaged with the annular latching part 12. Then, the elasticity of the first latching part 221 is used to engage the first latching part 221 with the annular latching part 12. At this time, both the second latching surface 2212 and the third latching surface 231 abut against the first latching surface 121, achieving pre-fixation of the camera. The housing assembly 2 and the camera 3 will not fall off the mounting base 1 and can rotate relative to the mounting base 1 to adjust the angle of the housing assembly 2 and the camera 3 according to monitoring needs. After adjustment, as shown... Figures 9 to 10As shown, tightening fastener 4 causes the locking part 42 to abut against the first locking surface 121 and apply a force towards the base 11 to the housing 21, thus pressing and fixing the housing 21 to the base 11 and restricting the rotation of the housing assembly 2 relative to the mounting base 1. At this time, the third locking surface 231 is always engaged with the first locking surface 121, and the second locking surface 2212 is separated from the first locking surface 121. The camera 3 abuts against the elastic abutment 13, completing the installation and fixing of the camera. Disassembly is performed in the reverse order.

[0066] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.

[0067] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
