Description

Technical Field

[0001] This application relates to the field of camera equipment technology, and in particular to a dome assembly structure and a camera. Background Technology

[0002] In dome or hemispherical cameras, the mounting cover is typically detachably attached to the base using screws. The mounting cover is hemispherical, housing a sphere. The fit between the mounting cover and the base not only protects the sphere but also prevents it from falling out. However, when adjusting the assembly angle of the sphere and mounting cover, the screws need to be loosened to detach the mounting cover from the base. Since the mounting cover is assembled from below the base, the screws are prone to falling out under gravity or even being lost, affecting the normal operation of the entire camera. Furthermore, screws are small parts, posing a risk of loss during disassembly and assembly, and making reassembly difficult. Utility Model Content

[0003] Therefore, it is necessary to provide a spherical cover assembly structure that not only facilitates the adjustment of the assembly angle of the fixed cover, but also reduces the risk of parts falling or being lost, thereby improving safety in use.

[0004] A spherical cover assembly structure includes an assembly base and a fixed cover with a limiting flange. The limiting flange is connected to the assembly base for limiting. The spherical cover assembly structure also includes a pressing seat and a fastener integrally connected to the pressing seat. One of the pressing seat and the assembly base has a limiting arm, and the other has a limiting groove. A portion of the limiting arm extends into the limiting groove. The fastener is detachably connected to the assembly base to switch between a locked state and an unlocked state. In the locked state, the pressing seat is locked to the assembly base by the fastener, and the limiting flange is clamped between the pressing seat and the assembly base. In the unlocked state, the fastener is unlocked relative to the assembly base, and the limiting arm engages with the groove wall of the limiting groove for limiting.

[0005] Understandably, the limiting flange and the limiting connection of the mounting base are used to ensure that the fixing cover will not easily detach from the mounting base. Furthermore, the cooperation between the fastener and the pressing seat allows the pressing seat to be secured to the mounting base when the fastener is locked, thus causing the limiting flange to clamp between the pressing seat and the mounting base, ensuring the assembly reliability of the fixing cover relative to the mounting base. Simultaneously, when the fastener is disassembled or unlocked relative to the mounting base, the limiting groove and limiting arm between the pressing seat and the mounting base limit the pressing seat to the mounting base, preventing it from detaching. Since the fastener and the pressing seat are connected as a single structure, the fastener will not easily detach; moreover, the pressing seat serves as the assembly reference for the fastener, reducing the risk of fastener loss. Thus, while facilitating the adjustment of the fixing cover's assembly angle, the risk of parts falling or being lost is reduced, improving safety during use.

[0006] In some embodiments, the pressing seat has a through hole, through which the fastener is detachably connected to the mounting base, and the fastener is movable within the through hole; the wall of the through hole has a limiting step, and in the unlocked state, the fastener is limited to the limiting step.

[0007] In some embodiments, the assembly base has an assembly ring portion and an assembly notch located on the outer periphery of the assembly ring portion. The limiting flange is limitedly connected to the assembly ring portion and is partially located in the assembly notch. The pressing seat is located at the assembly notch, and the limiting flange can be pressed between the edge of the assembly notch and the pressing seat.

[0008] In some embodiments, the assembly notch has a locking portion and a limiting portion. The locking portion has the limiting portion on both sides of the assembly base circumferentially. The locking portion is perpendicular to the axis of the fastener and is used to press and engage with the press-fit seat. The limiting portion can abut and limit the press-fit seat.

[0009] In some embodiments, the limiting arm protrudes from the locking part and includes an axial section and a radial section, which are connected and set at an angle. The axial section is connected to the locking part, and the radial section engages with the limiting groove on the pressing seat.

[0010] In some embodiments, one of the locking part and the pressing seat is provided with a positioning hole, and the other is provided with a positioning post, the positioning post being able to be inserted into the positioning hole.

[0011] In some embodiments, the mounting notch has a locking portion that mates with the press-fit seat. The locking portion has a fastening hole for fastening the fastener. The fastening hole has a gradually expanding section from the inside to the outside at one end facing the press-fit seat. In the unlocked state, the end of the fastener is located at the gradually expanding section.

[0012] In some embodiments, the assembly ring includes an annular groove recessed at one end of the assembly base and a limiting protrusion on the side wall of the annular groove; the assembly notch communicates with the annular groove, and the edge of the assembly notch is provided with a pressing platform protruding from the bottom wall of the annular groove.

[0013] In some embodiments, the limiting flange is recessed with an assembly groove, the pressing seat is protruded with a pressing protrusion, and the pressing protrusion is inserted into the assembly groove; or, the end of the fixing cover facing the assembly base is recessed with an assembly groove, and the side wall of the assembly groove facing the assembly base is defined as the limiting flange.

[0014] This application also provides a camera, including a sphere and the above-described dome assembly structure, wherein the sphere is confined within a fixed cover in the dome assembly structure. Attached Figure Description

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.

[0026] 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.

[0027] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature and the second feature are in indirect contact through an intermediate medium. Furthermore, "above," "over," and "on top" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0028] 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's specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0029] Please see Figure 1 , Figure 3 , Figure 5 , Figure 6 and Figure 7One embodiment of this application provides a spherical cover assembly structure, including an assembly base 10 and a fixed cover 20 with a limiting flange 21, the limiting flange 21 being limitedly connected to the assembly base 10. The spherical cover assembly structure also includes a pressing seat 30 and a fastener 40 integrally connected to the pressing seat 30. One of the pressing seat 30 and the assembly base 10 is provided with a limiting arm 51, and the other is provided with a limiting groove 52. A portion of the limiting arm 51 extends into the limiting groove 52. The fastener 40 is detachably connected to the assembly base 10 to switch between a locked state and an unlocked state. In the locked state, the pressing seat 30 is locked to the assembly base 10 by the fastener 40, and the limiting flange 21 is clamped between the pressing seat 30 and the assembly base 10; in the unlocked state, the fastener 40 is unlocked relative to the assembly base 10, and the limiting arm 51 is limitedly engaged with the groove wall of the limiting groove 52.

[0030] Understandably, the limiting flange 21 is used to limit the connection with the assembly base 10 to ensure that the fixing cover 20 will not easily detach from the assembly base 10. Furthermore, by utilizing the cooperation of the fastener 40 and the pressing seat 30, when the fastener 40 is locked to the assembly base 10 (i.e., switched to the locked state), the pressing seat 30 can be secured to the assembly base 10, thereby causing the limiting flange 21 to be clamped between the pressing seat 30 and the assembly base 10, ensuring the assembly reliability of the fixing cover 20 relative to the assembly base 10. Simultaneously, when the fastener 40 is disassembled and unlocked relative to the assembly base 10 (i.e., switched to the unlocked state), the limiting groove 52 and the limiting arm 51 between the pressing seat 30 and the assembly base 10 limit the pressing seat 30 to the assembly base 10, preventing the pressing seat 30 from detaching. Because the fastener 40 and the clamping seat 30 are connected as a single unit, even if the fastener 40 is disassembled from the mounting base 10, the fastener 40 will not detach from the clamping seat 30, thus ensuring that the fastener 40 will not easily detach from the mounting base 10 in the unlocked state. In other words, the clamping seat 30 serves as the assembly reference for the fastener 40, reducing the risk of loss of the fastener 40. In this way, while facilitating the adjustment of the mounting angle of the fixing cover 20, the risk of parts falling or being lost is reduced, improving safety in use.

[0031] When the assembly angle needs to be adjusted, the fastener 40 can be switched to the unlocked state to release the fastener to the assembly base 10 and the tightening force on the limiting flange 21. The user can then hold the fixing cover 20 and adjust its position to the target state. During this process, the pressing seat 30 is suspended below the assembly base 10 through the cooperation of the limiting arm 51 and the limiting groove 52, ensuring it will not fall off and will not interfere with the adjustment of the fixing cover 20. After adjustment, the user can hold the pressing seat 30 and switch the fastener 40 to the locked state, thereby using the locking mechanism between the pressing seat 30 and the assembly base 10 to clamp the limiting flange 21 and secure the fixing cover 20.

[0032] like Figures 1 to 3As shown, in some specific embodiments, the limiting arm 51 may protrude from the assembly base 10, and the limiting groove 52 may be recessed into the pressing seat 30. A portion of the limiting arm 51 extends into the limiting groove 52, allowing the limiting arm 51 to move within the limiting groove 52 during assembly and disassembly. When the pressing seat 30 is fastened to the assembly base 10 by the fastener 40, the limiting arm 51 will not move within the limiting groove 52.

[0033] Alternatively, the mounting base 10 may have a recessed limiting groove 52, and the pressing seat 30 may have a protruding limiting arm 51. As long as the limiting arm 51 and the limiting groove 52 can be used to limit the pressing seat 30 relative to the mounting base 10 and prevent it from detaching.

[0034] The following describes in detail the fit between the limiting groove 52 and the limiting arm 51 based on the specific structure of the assembly base 10 and the pressing seat 30.

[0035] like Figure 1 and Figure 4 As shown, the mounting base 10 has a through cavity 101 extending along its own axial direction. The fixing cover 20 is hemispherical, with open ends along its own axial direction. A limiting flange 21 is provided at the edge of the open end at the diameter for engaging with the mounting base 10 and the pressing seat 30. The other open end serves as a viewing window on the spherical core for obtaining a field of view. The end of the mounting base 10 opposite to the fixing cover 20 also has multiple mounting holes 102 spaced circumferentially for fixing with chassis screws. The cable for signal transmission between the spherical core and the chassis can be stored in the through cavity 101 of the mounting base 10.

[0036] Please see Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7 In some embodiments, the assembly base 10 has an assembly ring portion 11 and an assembly notch 12 located on the outer periphery of the assembly ring portion 11. A limiting flange 21 is limitedly connected to the assembly ring portion 11 and is partially located in the assembly notch 12. A pressing seat 30 is located at the assembly notch 12, and the limiting flange 21 can be pressed between the edge of the assembly notch 12 and the pressing seat 30.

[0037] Understandably, the assembly ring 11 is positioned around the outer periphery of the fixed cover 20 to ensure a stable assembly reference. The assembly notch 12 exposes the limiting flange 21 on the fixed cover 20. Therefore, when the pressing seat 30 is positioned at the assembly notch 12, it can precisely engage with the assembly base 10 to press the limiting flange 21. Furthermore, the assembly notch 12 effectively limits the assembly position of the pressing seat 30, particularly its movement along the circumference of the assembly base 10. The limiting flange 21 is annular, reducing assembly restrictions on the fixed cover 20.

[0038] like Figure 1 and Figure 2 As shown, in some specific embodiments, the assembly ring 11 includes an annular groove 111 recessed at one end of the assembly base 10 and a limiting protrusion 112 provided on the side wall of the annular groove 111. The limiting protrusion 112 is parallel to the bottom wall of the annular groove 111 and together limits the movable area of ​​the fixing cover 20. The side of the limiting flange 21 facing away from the bottom wall of the groove can be matched with the limiting protrusion 112 to prevent the fixing cover 20 from falling off relative to the assembly base 10. The aforementioned assembly notch 12 connects to the annular groove 111, which facilitates the exposure of part of the limiting flange 21.

[0039] Please continue reading. Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7 In actual assembly, taking the axis of the mounting base 10 as the vertical direction as an example, that is... Figure 5 In the vertical direction, the assembly ring 11 is typically located at the downward-facing end of the assembly base 10. When the fastener 40 is switched to the unlocked state, the fixing cover 20 can move downwards under its own weight, and the limiting flange 21 can overlap the side of the limiting protrusion 112 facing the bottom wall of the groove, thus limiting the fixing cover 20. Taking the limiting arm 51 located on the assembly base 10 as an example, the pressing seat 30 can then overlap the limiting arm 51 through the groove wall of the limiting groove 52 to limit the pressing seat 30. In this way, the fixing cover 20, the pressing seat 30, and the fastener 40 are all suspended at one end of the assembly base 10, reducing the risk of detachment.

[0040] like Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, furthermore, a pressing platform 13 can be provided near the edge of the annular groove 111 at the assembly notch 12, and the pressing platform 13 protrudes from the bottom wall of the annular groove 111. When the fastener 40 is switched to the locked state, the limiting flange 21 located at the assembly notch 12 can be pressed between the pressing platform 13 and the pressing seat 30. Therefore, when the pressing platform 13 protrudes from the bottom wall of the annular groove 111, it provides sufficient adjustment margin for the adjustment of the fixing cover 20 within the annular groove 111, which is beneficial for changing the position of the fixing cover 20. The edge of the pressing platform 13 can transition smoothly relative to the bottom wall of the groove, avoiding wear of the limiting flange 21 or stress concentration due to sharp corners. The projected length of the pressing platform 13 in the vertical direction can be the same as the projected length of the pressing seat 30 in the vertical direction, or the projected length of the pressing platform 13 can be greater than the projected length of the pressing seat 30, as long as the assembly reliability during pressing is guaranteed.

[0041] Please see Figure 1 , Figure 2 , Figure 3 and Figure 7 In some embodiments, the assembly notch 12 has a locking portion 121 and a limiting portion 122. The locking portion 121 has limiting portions 122 on both sides of the assembly base 10 circumferentially. The locking portion 121 is perpendicular to the axial direction of the fastener 40 and is used to press against the pressing seat 30. The limiting portion 122 can abut against and limit the pressing seat 30. That is, the assembly notch 12 is L-shaped and forms an L-shaped cavity to accommodate the pressing seat 30. The locking portion 121 is used to press against the pressing seat 30, and it is perpendicular to the axial direction of the fastener 40, which not only facilitates user operation but also ensures full surface contact with the pressing seat 30, improving reliability. The limiting portion 122 can limit the displacement of the pressing seat 30 along the circumferential direction of the assembly base 10, effectively preventing the fixing cover 20 from loosening due to vibration and other factors during long-term use, thereby ensuring the long-term stability and reliability of the entire assembly structure.

[0042] like Figure 1 and Figure 2 As shown, the assembly notch 12 further includes a mating portion 123, a locking portion 121, and a limiting portion 122. These three portions are connected in pairs and arranged at an angle to form an L-shaped cavity. The aforementioned pressing platform 13 is located at the end of the mating portion 123 opposite to the locking portion 121. The mating portion 123 is provided to limit the radial displacement of the pressing seat 30 along the assembly base 10.

[0043] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5 In some embodiments, the locking part 121 is provided with a fastening hole 103. The fastener 40 passes through the pressing seat 30 and is threadedly connected to the wall of the fastening hole 103, which not only facilitates disassembly and assembly but also ensures high connection reliability. The central axis of the fastening hole 103 is parallel to the central axis of the mounting base 10. The end of the fastening hole 103 facing the pressing seat 30 has a gradually expanding section 1031 from the inside to the outside; that is, along the axial direction of the mounting base 10, the expanding section 1031 gradually increases in diameter from the mounting base 10 towards the pressing seat 30. In the unlocked state, the end of the fastener 40 is located in the expanding section 1031. Specifically, the expanding section 1031 serves two purposes: firstly, it guides the connection between the fastener 40 and the mounting base 10, facilitating the fastener 40's smooth insertion into the fastening hole 103 and connection; secondly, in the unlocked state, it abuts against the end of the fastener 40, thereby limiting the fastener 40's movement. The gradually expanding section 1031 does not require internal threads.

[0044] Please continue reading. Figure 1 , Figure 2 , Figure 3 and Figure 5 In some embodiments, the press-fit seat 30 is provided with a through hole 301, through which the fastener 40 is detachably connected to the mounting base 10, and the fastener 40 can move within the through hole 301. The wall of the through hole 301 is provided with a limiting step. In the unlocked state, the fastener 40 is limited to the limiting step. That is, the through hole 301 is a stepped hole, including a large-diameter section and a small-diameter section, and the limiting step is located between the large-diameter section and the small-diameter section. The diameter of the large-diameter section is larger than the outer diameter of the fastener 40. The fastener 40 includes a smooth rod section 41 and a threaded section 42 connected to the smooth rod section 41, and the threaded section 42 is threadedly connected to the wall of the aforementioned fastening hole 103. When the fastener 40 is assembled relative to the press-fit seat 30, the threaded section 42 can pass through the small-diameter section of the through hole 301 until the smooth rod section 41 passes through the small-diameter section. The fastener 40 has a nut 43 protruding from one end away from the threaded section 42. The nut 43 can be pressed onto the side of the pressing seat 30 away from the locking part 121 when locked.

[0045] During assembly, the fastener 40 can be tightened to switch to the locked state. The threaded section 42 engages with the wall of the fastening hole 103, and the nut 43 presses against the side of the pressing seat 30 away from the locking part 121, thus locking the pressing seat 30 and the mounting base 10. Both work together to clamp the limiting flange 21 of the fixing cover 20, ensuring the fastening of the fixing cover 20. When unlocking is required, the fastener 40 is rotated in the opposite direction to switch to the unlocked state. The end of the threaded section 42 exits into the gradually expanding section 1031 of the fastening hole 103. At this time, part of the threaded section 42 is accommodated in the large-diameter section of the through hole 301, and the end of the threaded section 42 facing the smooth rod section 41 can be limited by the aforementioned limiting step to prevent the fastener 40 from falling off. When it is necessary to disassemble the fastener 40 relative to the pressing seat 30, the fastener 40 needs to be rotated out of the through hole 301.

[0046] Fastener 40 is a screw.

[0047] Alternatively, the fastener 40 can be a clamp, pin, buckle, or other fixing structure that can be detachably connected to the mounting base 10.

[0048] like Figure 1 , Figure 5 and Figure 7 As shown, in some specific embodiments, the press-fit seat 30 has a recess 303 at the end of the through hole 301 opposite to the mounting base 10. In the locked state, the nut 43 on the fastener 40 can be accommodated in the recess 303, reducing the risk of interference due to the fastener 40 protruding.

[0049] like Figures 1 to 3 As shown, in some embodiments, one of the locking part 121 and the pressing seat 30 is provided with a positioning hole 53, and the other is provided with a positioning pin 54, which can be inserted into the positioning hole 53. That is, the positioning hole 53 and the positioning pin 54 are used to position the pressing seat 30 relative to the assembly base 10, thereby improving the assembly reliability. When the fastener 40 is in the unlocked state, the positioning pin 54 can be disengaged from the positioning hole 53. When the fastener 40 is in the locked state, the positioning pin 54 is inserted into the positioning hole 53. Of course, it is also possible that in the unlocked state, part of the positioning pin 54 is still inserted into the positioning hole 53.

[0050] In this configuration, the locking part 121 may have a protruding positioning post 54, and the pressing seat 30 may have a positioning hole 53. Conversely, the locking part 121 may have a positioning hole 53, and the pressing seat 30 may have a protruding positioning post 54. The key is that the positioning post 54 and the positioning hole 53 can be used to achieve assembly positioning. This is merely an example.

[0051] Please see Figures 1 to 3 In some embodiments, the limiting arm 51 protrudes from the locking part 121 and includes an axial section 511 and a radial section 512, which are connected and angled together. The axial section 511 connects to the locking part 121, and the radial section 512 engages with the limiting groove 52 on the pressing seat 30. That is, the limiting arm 51 is arranged in an inverted L-shape, with the axial section 511 along the axial direction of the mounting base 10 and the radial section 512 along the radial direction of the mounting base 10. When the fastener 40 is in the unlocked state, the groove wall of the limiting groove 52 simply overlaps the side wall of the radial section 512 facing the axial section 511. This arrangement simplifies the structure and facilitates manufacturing while still satisfying the limiting function. The side of the radial section 512 facing away from the axial section 511 may also have a chamfer, which facilitates the assembly of the pressing seat 30.

[0052] The pressing seat 30 has a recessed limiting groove 52 on one side radially inward along the mounting base 10 to engage with the limiting arm 51. Two limiting grooves 52 may be provided, spaced apart. A through hole 301 is located between the two limiting grooves 52 and does not communicate with either groove. Each limiting groove 52 corresponds to one limiting arm 51. The engagement of the two sets of limiting grooves 52 and limiting arms 51 improves connection reliability, maintains the stability of the pressing seat 30 in the unlocked state, and further reduces the risk of falling.

[0053] The two limiting grooves 52 can pass through the pressing seat 30 on opposite sides. Of course, they can also not pass through. This is just an example.

[0054] Please see Figures 1 to 3In some embodiments, the outer peripheral sidewall of the limiting flange 21 is radially recessed with an assembly groove 2101, and the pressing seat 30 is protruding with a pressing protrusion 302, which is inserted into the assembly groove 2101. That is, the pressing protrusion 302 can be used to connect the fixing cover 20 and the pressing seat 30 into an integral structure by means of the insertion and engagement of the pressing protrusion 302 relative to the assembly groove 2101, thereby further improving the fixing effect of the fixing cover 20. Moreover, it is precisely because of the limiting engagement between the fixing cover 20 and the assembly base 10 that the risk of the pressing seat 30 and the fastener 40 falling off can be further reduced.

[0055] Alternatively, the end of the fixing cover 20 facing the mounting base 10 is recessed with a mounting groove 2101, and the side wall of the mounting groove 2101 facing the mounting base 10 can serve as the aforementioned limiting flange 21. In this case, the end of the fixing cover 20 remains flush, reducing wear and assembly interference, and reducing the space occupied.

[0056] Alternatively, the pressing seat 30 can also be directly pressed onto the side wall of the limiting flange 21 that is away from the assembly base 10, specifically, the side wall of the limiting flange 21 that is away from the pressing platform 13.

[0057] like Figure 7 As shown, this application also provides a camera, including a sphere and the aforementioned dome assembly structure, wherein the sphere is confined within a fixed cover 20 in the dome assembly structure. A viewing window on the sphere is exposed via an opening in the fixed cover 20 to ensure a wide field of view.

[0058] 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.

[0059] 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.
