Abstract
Description
Technical Field
[0001] This utility model relates to the field of security equipment technology, and in particular to a camera structure and a security monitoring system. Background Technology
[0002] In existing camera mounting structures, the camera mounting structure typically consists of three core components: a mounting base, a housing, and the camera. During assembly, the mounting base and housing apply pressure from both sides of the camera's axis. The mounting base and housing are pre-assembled and locked together using threaded fasteners or snap-fit mechanisms. This pre-assembled assembly is initially fixed at the factory to facilitate transportation and subsequent overall installation. When the camera needs to be mounted on a wall or ceiling, the installer must rotate and adjust the camera's angle to achieve the desired monitoring field of view.
[0003] However, if the locking force applied to the mounting base and the housing during the pre-assembly stage is too large, the frictional resistance between the mounting base and the housing and the camera sphere will increase significantly. This will make it extremely difficult to rotate and adjust the sphere during on-site installation, and may even require the use of tools or complete disassembly of the pre-assembly to complete the angle adjustment. If the locking force is too small, although it is convenient to adjust on-site, the pre-assembly is susceptible to vibration, external impact and other interference during transportation or long-term use, which may cause displacement between the sphere and the mounting base / housing, affecting the positioning stability of the camera. Utility Model Content
[0004] The first aspect of this utility model provides a camera structure to solve the defect of the contradiction between the locking force applied to the mounting base and the pressure shell in the prior art. By moving the locking force generation mechanism from the existing assembly process to the moment of installation, the dilemma of locking force in the pre-assembly stage is balanced, which not only ensures the stability during transportation and after installation, but also improves the frictional resistance when adjusting the angle on site.
[0005] The second aspect of this utility model provides a security monitoring system.
[0006] The camera structure provided by this utility model includes: Camera; Mounting base, used for installation at the target location; A pressure shell is detachably disposed on one side of the mounting base. The interior of the pressure shell is hollow to restrict the installation space. The camera is disposed in the installation space, and the lens of the camera is exposed through an opening at the bottom of the pressure shell. An elastic element is disposed within the mounting space, one end of the elastic element abuts against the camera, the other end of the elastic element extends toward the mounting base, and the elastic element at least partially extends out of the mounting base away from the pressure shell.
[0007] According to the camera structure provided by this utility model, the elastic element is fixed to one of the camera, the mounting base, and the pressure shell.
[0008] According to the camera structure provided by this utility model, the elastic element is fixed to the pressure shell; The elastic element includes: The cantilever has one end connected to the inner wall of the pressure shell and the other end extending toward the installation space; An abutment arm is connected to the cantilever arm, one end of which abuts against the camera, and the other end of which extends toward the mounting base, with the abutment arm at least partially extending out of the mounting base away from the pressure shell.
[0009] According to the camera structure provided by this utility model, the end of the abutment arm facing the camera is provided with an arc-shaped surface, which is used to abut against the camera.
[0010] According to the camera structure provided by this utility model, it also includes an adjusting member, which is located at the end of the elastic member away from the camera, and is used to adjust the length of the elastic member.
[0011] According to the camera structure provided by this utility model, the adjusting member includes at least one adjusting washer, which is detachably disposed at the end of the elastic member away from the camera; When multiple adjusting washers are provided, all the adjusting washers are stacked along the extension and contraction direction of the elastic element.
[0012] According to the camera structure provided by this utility model, multiple elastic elements are provided, and the multiple elastic elements are spaced apart and distributed along the circumference of the camera.
[0013] According to the camera structure provided by this utility model, it also includes: A guide plate is located on the side of the pressure shell facing the mounting base. The guide plate is provided with guide openings. The number and position of the guide openings correspond one-to-one with the number and position of the elastic elements. The end of each elastic element away from the camera can be movably inserted into the corresponding guide opening.
[0014] According to the camera structure provided by this utility model, the guide plate is covered on the bottom of the mounting base.
[0015] The security monitoring system provided by this utility model includes the camera structure described in any of the preceding claims.
[0016] The camera structure provided by this invention simplifies the assembly process through the reaction force transmission mechanism of the elastic element. Users only need to apply force once to achieve adaptive locking via the elastic element, thus reducing the complexity caused by the coordinated operation of multiple components during assembly. Secondly, the mounting base only serves as an external fixation device, decoupling it from the camera's fixing function, improving structural redundancy and enhancing compatibility to adapt to different target locations. Furthermore, the elastic element absorbs and disperses external forces during deformation, enhancing the camera's vibration resistance and long-term stability.
[0017] Compared with the prior art, the camera structure provided by this utility model moves the locking force generation mechanism from the existing assembly process to the moment of installation, and uses the reaction force of the target position to drive the elastic element to achieve dynamic adaptive locking. From another perspective, the embodiment of this utility model balances the dilemma of locking force in the pre-assembly stage, which not only ensures the stability during transportation and after installation, but also improves the frictional resistance when adjusting the angle on site. At the same time, it achieves anti-vibration locking after installation through elastic deformation. Attached Figure Description

[0027] Figure 1 This is a schematic diagram of the axonometric structure of the camera structure provided in this embodiment of the utility model; Figure 2 This is an exploded structural diagram of the camera structure provided in this embodiment of the utility model.
[0028] See Figure 1 and Figure 2The first aspect of this utility model provides a camera structure, which includes a camera 100, a mounting base 200, a pressure shell 300, and an elastic element 400. The mounting base 200 is used to fix the camera to a target location such as a wall or ceiling, providing basic support. The pressure shell 300 is detachably disposed on one side of the mounting base 200, and its interior is hollow to form an installation space 310. The camera 100 is placed in the installation space 310, and the lens of the camera 100 is exposed through an opening at the bottom of the pressure shell 300 to ensure an unobstructed monitoring field of view.
[0029] The elastic element 400 is located in the mounting space 310. One end of the elastic element 400 abuts against the camera 100, and the other end extends toward the mounting base 200 and at least partially extends out of the mounting base 200 away from the pressure shell 300. The elastic element 400 can undergo elastic deformation when subjected to force, and the camera 100 is locked by transmitting the reaction force.
[0030] In one optional embodiment, the elastic element 400 can be an elastic arm integrally formed with the pressure shell 300, or it can be a separately provided spring or rubber pad. For example, the elastic element 400 adopts an L-shaped elastic arm, with one end contacting the camera 100 and the other end extending to the surface of the target position. In another optional embodiment, the elastic element 400 is a helical spring, with one end embedded in the groove of the camera 100 housing and the other end passing through the hole in the mounting base 200 and contacting the target position.
[0031] It should be noted that the shape and number of the elastic element 400 can be adjusted according to installation requirements. For example, multiple parallel elastic arms can be used to distribute the force, or a ring spring can be used to enhance stability. The mounting base 200 and the pressure shell 300 can be connected by a snap-fit protrusion and a complementary groove, which can be quickly disassembled without screws or tools. The connection method between the mounting base 200 and the pressure shell 300 can be found in the existing technology adaptation design, and will not be described in detail here.
[0032] The camera structure is a pre-installed product (delivered to the customer as a single unit). During installation, the user first selects the target location (such as a wall) for the mounting base 200. Since the camera 100 is pre-placed within the mounting space 310 of the housing 300, but the end of the elastic element 400 furthest from the camera 100 is not yet in contact with the target location, the locking force of the elastic element 400 is relatively small. The user can freely change the angle of the camera 100 lens without the elastic element 400 interfering with the angle adjustment. After the camera 100 lens angle is adjusted, the user can directly fix the mounting base 200 to the target location. Furthermore, the elastic element 400 ensures the stability of the camera structure during transportation.
[0033] During the process of pressing the mounting base 200 into the target position, the specific installation method is not limited. For example, the mounting base 200 can be fixed to the target position with fasteners, or it can be glued, welded, etc. The surface of the target position abuts against the elastic element 400. The elastic element 400 exposed on the outside of the mounting base 200 will retract into the installation space 310. The elastic element 400 deforms under force, and the interaction between the elastic element 400 and the target position generates a reaction force. This reaction force is then transmitted to the camera 100 through the elastic element 400, forming a two-way locking mechanism. That is, the reaction force of the target position is transmitted to the camera 100 through the elastic element 400, while the force applied by the pressure shell 300 directly acts on the camera 100 from the bottom.
[0034] The entire process can be completed with a single force application. After installation, the elastic element 400 will remain in a compressed state, maintaining the locking force on the camera 100 to ensure that the camera 100 remains stable under vibration or external interference.
[0035] See Figure 1 and Figure 2 It is understood that the camera structure provided in this embodiment simplifies the assembly process through the reaction force transmission mechanism of the elastic element 400. Users only need to apply force once to achieve adaptive locking via the elastic element 400, thus reducing the complexity caused by the collaborative operation of multiple components during assembly. Secondly, the mounting base 200 only undertakes the external fixing function, decoupling its function from fixing the camera 100, improving the structural redundancy of the mounting base 200, enhancing compatibility, and adapting to different target location environments. Furthermore, the elastic element 400 can absorb and disperse external forces during deformation, enhancing the vibration resistance and long-term stability of the camera 100.
[0036] Compared with the prior art, the camera structure provided by this utility model embodiment moves the locking force generation mechanism from the existing assembly process to the moment of installation, and uses the reaction force of the target position to drive the elastic element 400 to achieve dynamic adaptive locking. This utility model embodiment balances the dilemma of locking force in the pre-assembly stage, ensuring stability during transportation and after installation, improving frictional resistance when adjusting the angle on site, and achieving anti-vibration locking after installation through elastic deformation.
[0037] In an optional embodiment of this utility model, the elastic element 400 serves as the core component for transmitting reaction force. Its positional change does not affect the overall locking mechanism's functionality. Therefore, the elastic element 400 can be selectively disposed in one of the camera 100, the mounting base 200, or the pressure shell 300.
[0038] In specific implementations, the elastic element 400 can be a standalone component or integrated with other components, with the layout optimized according to installation requirements. For example, in an optional embodiment, the elastic element 400 is directly disposed on the housing of the camera 100. If the surface of the camera 100 has a groove, one end of the elastic element 400 is embedded in the groove and fixed to the housing of the camera 100, while the other end extends toward the mounting base 200.
[0039] In another alternative embodiment, the elastic element 400 is integrated inside the mounting base 200. If the base has a receiving cavity, the elastic element 400 is placed inside the cavity, with one end contacting the camera 100 and the other end extending out of the base to contact the target position.
[0040] In another optional embodiment, the elastic element 400 is integrally formed with the pressure shell 300. For example, the inner wall of the pressure shell 300 is provided with an elastic cantilever structure, which serves as the elastic element 400 directly abutting against the camera 100 and the target position. These positions all support the deformation of the elastic element 400 when subjected to force and transmit the reaction force, ensuring the consistency of the locking effect and simplifying the production and assembly process.
[0041] When the elastic element 400 is installed on the camera 100, the user applies force to the pressure shell 300, and the pressure shell 300 transmits the force to the camera 100. The elastic element 400 undergoes elastic deformation due to the force, and the rebound force generated by the deformation acts directly on the camera 100 to form a lock. At the same time, the end of the elastic element 400 that extends to the target position receives the reaction force, further enhancing the locking effect.
[0042] If the elastic element 400 is located on the mounting base 200, the applied force causes the pressure shell 300 to be compressed. The pressure is transferred from the pressure shell 300 to the camera 100, and then to the elastic element 400. The elastic element 400 deforms in the base cavity, transmitting the reaction force at the target position to the camera 100. When the elastic element 400 and the pressure shell 300 are integrated, the reaction force transmission mechanism is as described above.
[0043] Regardless of the position of the elastic element 400, its working principle is based on the transformation of elastic deformation into a two-way locking force: the reaction force at the target position is transmitted to the camera 100 through the elastic element 400, and the pressure shell 300 applies force directly to the camera 100 from the bottom of the camera 100. The two work together to ensure that the camera 100 is stably fixed.
[0044] It should be noted that after installation, when adjusting the angle, the user can directly rotate the camera 100. The elasticity of the elastic element 400 allows the camera 100 to be finely adjusted in position without loosening any parts. The entire process is completed in a single action, making it easy to operate.
[0045] It is understood that the camera structure provided in this embodiment of the present invention improves structural adaptability and production flexibility through the optional design of the elastic element at position 400, and can be adapted to diverse installation scenarios without redesigning the overall architecture, thereby reducing manufacturing costs.
[0046] Compared with the fixed locking method in the background technology, which causes the contradiction of the preset locking force (too large makes adjustment difficult, too small makes stability insufficient), in the embodiment of this utility model, the elastic element 400 can achieve dynamic locking force self-adaptation through elastic deformation at different positions. The initial locking force is low during installation, which is convenient for angle adjustment. During long-term use, the elastic rebound maintains vibration resistance and can prevent the camera 100 from shifting.
[0047] Meanwhile, the flexibility of position simplifies the assembly process. For example, integrating the elastic element 400 with the camera 100 or the pressure shell 300 can reduce the number of independent parts, shorten the assembly time, and improve the complexity of multi-part collaborative locking in the prior art.
[0048] Figure 3 This is a schematic diagram of the axial structure of the pressure shell and elastic element provided in the embodiment of this utility model.
[0049] See Figure 3 In an optional embodiment of this utility model, the elastic element 400 is disposed on the pressure shell 300. The elastic element 400 includes a cantilever 410 and an abutment arm 420. One end of the cantilever 410 is fixedly connected to the inner wall of the pressure shell 300, and the other end extends into the mounting space 310. The abutment arm 420 is connected to the cantilever 410, with one end abutting against the outer shell of the camera 100, and the other end extending toward the mounting base 200 and partially extending beyond the base on the side away from the pressure shell 300. The cantilever 410 serves as a deformation fulcrum, converting the force on the pressure shell 300 into multi-directional displacement and elastic deformation of the abutment arm 420, thereby achieving efficient transmission of the reaction force.
[0050] In specific implementations, the cantilever 410 and the abutment arm 420 can be integrally injection molded (such as an L-shaped or Y-shaped branch structure) or assembled separately. For example, in an optional embodiment, the cantilever 410 is an arc-shaped sheet structure, with its fixed end embedded in the groove of the inner wall of the pressure shell 300, and its free end connected to the abutment arm 420; the two ends of the abutment arm 420 can be respectively provided with hemispherical rubber pads, which directly contact the target position and the outer shell of the camera 100 to increase friction.
[0051] In another alternative embodiment, the cantilever 410 uses a helical spring instead of a sheet structure. One end of the spring is welded to the inner wall of the pressure shell 300, and the other end is connected to the abutment arm 420. The end of the abutment arm 420 facing the mounting base 200 is a tapered metal head that passes through the hole in the mounting base 200 to contact the target position, which is suitable for high-intensity vibration environments. The end of the abutment arm 420 that abuts against the camera 100 can refer to the hemispherical rubber pad design in the previous embodiment.
[0052] During the process of fixing the mounting base 200 to the target position, the camera 100 is driven by force to deform the abutment arm 420. The deformation of the abutment arm 420 causes the cantilever 410 to move. The end of the abutment arm 420 that contacts the camera 100 is subjected to force, and the end that extends to the target position receives the reaction force of the target position and transmits the reaction force back to the camera 100. After installation, the elastic deformation of the abutment arm 420 forms a locking mechanism, which can ensure the stability of the camera 100 without additional operation.
[0053] See Figure 3 It is understood that in the camera structure provided by this embodiment of the present invention, the abutment arm 420 acts as a deformation hub, converting the force applied by the user into a controllable elastic displacement, so that the locking force is adaptively adjusted according to the flatness of the target position. Compared with the contradiction of preset locking force in the background technology (too large makes adjustment difficult, too small makes it easy to loosen), this embodiment of the present invention provides low initial resistance during the installation stage to facilitate rotational adjustment, and elastic rebound after locking maintains vibration resistance, balancing the inherent conflict between stability and flexibility.
[0054] In an optional embodiment of this invention, the end of the abutment arm 420 facing the camera 100 is provided with an arc-shaped surface. This arc-shaped surface is used to abut against the camera 100 housing. The arc-shaped surface can increase the contact area, disperse the pressure distribution, and prevent damage to the camera 100 housing due to local stress concentration. The arc-shaped surface can be a smooth convex surface or a concave surface, and its specific shape can be adapted to the contour of the camera 100 housing. For example, in an optional embodiment, the contact end of the abutment arm 420 adopts a hemispherical concave surface, the radius of curvature of which matches the spherical surface of the camera 100 housing to ensure uniform force distribution.
[0055] During installation, due to the curved surface characteristics, the applied force is evenly distributed to the camera 100 housing, preventing excessive local pressure. When the elastic element 400 deforms, the curved surface continues to conform to the camera 100 surface, ensuring stable transmission of the reaction force. The reaction force at the target position is transmitted to the curved surface via the abutment arm 420 and then acts on the camera 100. When adjusting the angle, the user rotates the pressure shell 300; the smooth curved surface allows the camera 100 housing to slide, reducing frictional resistance.
[0056] It is understood that the arc-shaped surface design in the camera structure provided by this utility model embodiment can effectively reduce the risk of stress concentration in the camera 100 housing and improve the durability of the equipment structure. Compared with the contradiction in the preset locking force in the background technology (too large leads to housing damage or difficulty in adjustment, too small leads to insufficient stability), this utility model embodiment provides a low-resistance contact interface during the installation stage through uniform pressure distribution, which facilitates flexible angle adjustment; in long-term use, the arc-shaped surface can enhance contact stability, effectively suppress micro-displacement caused by vibration, and improve the loosening problem caused by the dispersion of locking force in the background technology.
[0057] An optional embodiment of this utility model further includes an adjusting member, which is disposed at the end of the elastic member 400 away from the camera 100, and is used to adjust the length of the elastic member 400. The adjusting member allows the user to fine-tune the extension of the elastic member 400 according to the installation environment, thereby optimizing the adaptability of the locking force. From another perspective, the adjusting member can achieve dynamic adjustment of the locking force by changing the effective length of the elastic member 400, without the need to replace parts or reassemble.
[0058] In specific implementations, the adjusting component can be a mechanically adjustable structure or other equivalent form. For example, in one optional embodiment, the adjusting component is a threaded knob, whose threaded rod is threadedly connected to the end of the elastic element 400. By rotating the threaded knob, the thread engagement depth between the threaded knob and the elastic element 400 is changed, thereby changing the length of the elastic element 400. In another optional embodiment, the adjusting component adopts a sliding snap-fit structure, and the length of the protruding end of the elastic element 400 is changed by a displacement slider. For example, the elastic element 400 itself is set as a two-section split structure, and the two sections are slidably connected by a slider. One section can slide and extend longitudinally relative to the other section and has a locking function. By setting the position of the adjusting component, the user can flexibly handle different target locations (such as uneven walls or soft ceilings) at the installation site, ensuring the consistency of reaction force transmission efficiency.
[0059] During installation, the user adjusts the length of the elastic element 400 using the adjustment mechanism, such as by rotating the threaded knob or sliding the latch, causing the elastic element 400 to extend or retract towards the target position. After adjustment, the end of the elastic element 400 furthest from the camera 100 contacts the target position, and its length change directly affects the strength of the reaction force transmission. When the user applies force to the camera 100, the rebound force generated by the deformation of the elastic element 400 works synergistically with the adjusted length, and the reaction force at the target position is transmitted to the camera 100 through the elastic element 400. At the same time, the pressure shell 300 applies force directly to the camera 100. In this process, if the length of the elastic element 400 increases, the locking force is enhanced; if the length decreases, the locking resistance is reduced, facilitating angle adjustment.
[0060] It is understood that in the camera structure provided by this utility model embodiment, the design of the adjusting component effectively improves the adjustability of the locking force and the environmental adaptability. Users can fine-tune the length of the elastic component 400 according to the actual installation scenario to optimize the initial locking resistance and long-term stability.
[0061] In contrast to the contradictory locking force presets in the background technology (too large leads to difficulty in adjustment, too small causes easy loosening), this utility model embodiment enhances vibration resistance and prevents camera displacement during long-term use through on-site dynamic adjustment. Simultaneously, the adjustment mechanism simplifies compatibility issues for different target locations; for example, the length of the elastic element 400 can be shortened to reduce pressure on soft ceilings, or the elastic element 400 can be extended to strengthen locking in high-vibration environments.
[0062] In an optional embodiment of this utility model, the adjusting component includes at least one adjusting washer, which is detachably disposed at the end of the elastic member 400 away from the camera 100. When multiple adjusting washers are provided, all adjusting washers are stacked along the length direction (extension direction) of the elastic member 400. This embodiment allows for flexible adjustment of the extension length of the elastic member 400 by increasing or decreasing the number or thickness of the washers, thus optimizing the adaptability of the locking force. The adjusting washer is an independent ring structure, detachably installed at the end of the elastic member 400 away from the camera 100, and its material and size can be configured in various ways.
[0063] In one optional embodiment, the adjusting washer is a rubber ring with an inner diameter matching the outer contour of the elastic element 400. The user can directly slip it onto the end of the elastic element 400 furthest from the camera 100. Each washer is 1mm thick and is used for fine-tuning the locking force (e.g., to accommodate slightly uneven wall surfaces). In another optional embodiment, multiple metal washers are stacked (e.g., 2-3), each 0.5mm thick, and fixed by nested slots. This is suitable for scenarios requiring enhanced locking in high-vibration environments.
[0064] The shape of the adjustable washers can be expanded; for example, wavy washers can distribute pressure, or washers with threaded interfaces can be easily adjusted by screwing. The core function is to provide an adjustable length mechanism. By increasing or decreasing the number of washers, users can flexibly address differences in target locations at the installation site (e.g., reducing washers on soft ceilings to reduce pressure, and increasing washers on hard walls to strengthen the locking).
[0065] Before installation, the user selects and adjusts the number of washers according to the characteristics of the target location. For example, multiple washers can be stacked on uneven walls to increase the length of the elastic element 400. After the washers are placed at the ends of the elastic element 400, during the fixing of the mounting base 200, the elastic element 400 deforms under force. The washers stacked at its ends contact the target location, and the reaction force at the target location is transmitted to the elastic element 400 through the washers, and then to the camera 100. At the same time, the pressure shell 300 applies force directly to the camera 100 from the bottom. After stacking the washers, the effective length of the elastic element 400 increases, the reaction force transmission is enhanced, and the locking is more secure.
[0066] It is understood that in the camera structure provided by this utility model embodiment, the adjusting washer can effectively improve the fine control of the locking force and environmental adaptability. Users can fine-tune the length by increasing or decreasing the number of adjusting washers, thereby optimizing the initial adjustment resistance and long-term vibration resistance.
[0067] In contrast to the contradictory locking force presets in the background technology (too large forces make angle adjustment difficult, while too small forces easily loosen), this utility model embodiment allows for flexible on-site adjustment, maintaining stable locking during long-term use and preventing displacement caused by vibration. Furthermore, the design of superimposed washers simplifies compatibility issues for different target locations; for example, superimposed washers can compensate for height differences on sloping ceilings.
[0068] In an optional embodiment of this invention, multiple elastic elements 400 are provided, arranged at intervals and evenly distributed along the circumference of the camera 100. In optional embodiments, they can also be arranged with varying density, i.e., unevenly distributed. This ring array layout can enhance the balance and stability of the locking force by distributing force at multiple points. Furthermore, the multiple elastic elements 400 operate independently, adaptively adjusting the pressure at each point according to the flatness of the target location, thus avoiding localized stress concentration.
[0069] In specific implementations, the number, shape, and distribution of the elastic elements 400 can be configured in various ways. For example, in an optional embodiment, three L-shaped elastic arms are used, which are arranged in a ring around the camera housing at 120° intervals. One end of each L-shaped elastic arm contacts the camera housing, and the other end extends to the outside of the mounting base 200.
[0070] In another optional embodiment, six helical springs are provided, evenly distributed at 60° intervals around the camera 100. One end of each spring is embedded in the housing of the camera 100, and the other end passes through the hole in the mounting base 200 to contact the target position. Through the circumferentially uniform distribution design, this embodiment of the invention can cope with local unevenness at the target position (such as wall protrusions or depressions), ensuring a consistent distribution of locking force.
[0071] During the process of the user fixing the base 200 to the target position, multiple elastic elements 400 are simultaneously subjected to force and deformed. Each elastic element 400 independently transmits reaction force. The end of the elastic element 400 that extends to the target position contacts the target position and generates reaction force, which is transmitted to the camera 100 housing through the elastic element 400. At the same time, the pressure shell 300 applies force directly to the camera 100.
[0072] Because the elastic elements 400 are uniformly distributed circumferentially, the reaction force at the target location is dispersed and transmitted to more than 100 contact points of the camera, forming a ring-shaped locking force field. If there is local unevenness at the target location (such as a tilted ceiling), some elastic elements 400 deform more to compensate for the height difference, while other elastic elements 400 remain unchanged, and the overall locking force remains balanced.
[0073] It is understood that in the camera structure provided by this embodiment, the multi-point uniform distribution can effectively improve the balance of locking force and the resistance to off-center loads, effectively suppressing the tilt displacement of the camera 100 caused by vibration or external forces. Compared with the insufficient locking force in the prior art, this embodiment applies force uniformly in the circumferential direction. During long-term use, the elastic element 400 deforms in tandem to absorb vibration energy, which can avoid the failure of a single locking point. At the same time, the circumferential distribution enhances the adaptability to uneven target positions. For example, for curved walls or inclined ceilings, the multi-point pressure can adaptively compensate for height differences.
[0074] An optional embodiment of this utility model further includes a guide plate located on the side of the pressure shell 300 facing the mounting base 200, with guide openings on its surface. The number and position of the guide openings correspond one-to-one with the number and position of the elastic elements 400. The end of the elastic element 400 away from the camera 100 is movably inserted into the guide opening. The guide openings can constrain the movement path of the elastic element 400, ensuring its positional stability during deformation and preventing displacement or jamming.
[0075] In specific implementations, the shape and size of the guide opening can be configured in various ways. For example, in one optional embodiment, the guide opening is a circular through hole with a diameter slightly larger than the diameter of the end of the elastic element 400, allowing the elastic element 400 to slide vertically. In another optional embodiment, the guide opening is designed as an elongated slot, supporting fine-tuning of the end of the elastic element 400 in the horizontal direction to compensate for unevenness at the target position. The guide plate can be made of engineering plastics or lightweight metals, and its core function is to provide a precise movement channel for the elastic element 400. Through the one-to-one correspondence design of the guide openings, the end of the elastic element 400 can always move along a predetermined path during the application of force, ensuring the reliability and consistency of the reaction force transmission.
[0076] During the process of fixing the base 200 to the target position, the elastic element 400 deforms under force. The end of the elastic element 400 away from the camera 100 slides or moves within the guide opening. The guide opening constrains the movement direction of the end of the elastic element 400, preventing it from deviating or shaking. If there is local unevenness at the target position (such as a wall protrusion), the guide opening allows the end of the elastic element 400 to adaptively adjust its position, maintaining the stability of the reaction force transmission path.
[0077] It is understood that in the camera structure provided by this utility model embodiment, the guide plate can effectively improve the accuracy and stability of the movement of the elastic element 400, ensuring that the reaction force is efficiently transmitted to the camera 100. Compared with the rotation jamming problem caused by the multi-component coordinated locking in the background art, this utility model embodiment, through the constraint mechanism of the guide opening, can optimize the deformation path of the elastic element 400 during the installation stage, facilitating the flexible positioning of the camera 100; in long-term use, the guide plate can suppress the displacement of the elastic element 400 caused by vibration, enhance the durability of the locking force, and improve the loosening defect caused by the dispersion of locking force in the background art.
[0078] In an optional embodiment of this utility model, the guide plate covers the bottom of the mounting base 200, that is, the guide plate acts as a covering component and fits tightly against the lower surface of the mounting base 200. The guide plate can be combined with the mounting base 200 by a fixed connection (such as a snap, screw, or adhesive) or by an integral molding method. The guide openings (the number and position of which correspond one-to-one with the elastic element 400) provided on its surface penetrate the guide plate, allowing the end of the elastic element 400 away from the camera 100 to move through it.
[0079] In specific implementations, the material and shape of the guide plate can be configured in various ways. In one optional embodiment, the guide plate is an aluminum alloy sheet, which is fixed to the bottom of the mounting base 200 by screws. The guide opening is a circular through hole with a diameter slightly larger than the end diameter of the elastic element 400, allowing the elastic element 400 to slide vertically.
[0080] In another alternative embodiment, the guide plate and the mounting base 200 are integrally injection molded (e.g., engineering plastic), and the guide opening is designed as a long strip-shaped slot to support horizontal fine adjustment of the end of the elastic element 400, adapting to local unevenness at the target position (e.g., wall protrusion).
[0081] It is understood that in the camera structure provided in this embodiment of the present invention, the guide plate covers the bottom of the mounting base 200, and its covering structure forms a physical barrier, directly blocking the external environment from interfering with the internal components of the mounting base 200. During installation, the guide plate and the end of the elastic member 400 are precisely matched, which can both constrain the movement path of the elastic member 400 and close the bottom space of the mounting base 200.
[0082] The second aspect of this utility model provides a security monitoring system, which includes the camera structure described in any of the foregoing embodiments. It is understood that the security monitoring system in this embodiment, because it includes the camera structure described in any of the foregoing embodiments, also has the effects of the camera structure described in any of the foregoing embodiments. The specific effects can be referred to the foregoing description, and will not be repeated here.
[0083] It should be noted that the technical solutions in the various embodiments of this utility model can be combined with each other, but the basis for such combination is that they can be implemented by those skilled in the art. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist, that is, it is not within the protection scope of this utility model.
[0084] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
