Description

Technical Field

[0001] This utility model relates to the field of security camera technology, and more specifically, to a PTZ camera mount and a camera. Background Technology

[0002] In the modern security field, outdoor surveillance cameras, as important security equipment, are widely used in various outdoor scenarios such as streets, parks, and traffic intersections, undertaking the important responsibilities of real-time monitoring and security prevention. However, outdoor environmental conditions are complex and changeable. Natural factors such as high temperature, severe cold, wind and rain, and ultraviolet radiation continuously act on surveillance cameras and their components, posing severe challenges to their structural stability and service life. Regarding the mounting structure of cameras, the stability of the connection between the mounting base and the handle is fundamental to ensuring the normal operation of the camera. For example, a surveillance camera disclosed in CN212137790U, suitable for outdoor use, employs a design where the entire mounting base is fixed to the handle. However, in actual outdoor use, due to prolonged exposure to the natural environment, the handle and mounting base frequently experience drastic temperature changes, resulting in thermal expansion and contraction. Over time, this repeated thermal expansion and contraction can gradually loosen the connection between the handle and the mounting base, eventually creating gaps. The appearance of these gaps not only causes the camera to shake under the influence of external forces such as wind, affecting the stability and clarity of the monitoring image and reducing the monitoring effect; more seriously, the gaps may become channels for impurities such as moisture and dust to enter, accelerating the corrosion and aging of internal components, shortening the lifespan of the camera, increasing maintenance costs and frequency, and posing a threat to the stable operation of outdoor monitoring systems.

[0029] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model. Example 1

[0030] like Figure 1-8As shown in this embodiment, the present invention provides a PTZ camera mounting base 1, which includes a cylindrical body 1a, a cantilever portion 1b, a partition plate 1c, a power module 5, and a steering bracket 2. The cylindrical body 1a is a hollow cylindrical structure made of metal or engineering plastic, with its central axis set vertically to ensure the stability and load-bearing capacity of the overall structure. The lower end of the body 1a has an opening facing downwards for connection with the steering bracket 2. The outer periphery of the body 1a extends radially outward to form a hollow cantilever portion 1b, which is a horizontally arranged tubular structure. A connecting seat 4 is fixedly installed at the pre-installation position of the camera. The outer end of the cantilever portion 1b is detachably connected to the connecting seat 4 by a buckle or fastener, thereby installing the entire camera at the pre-installation position. The main body 1a and the cantilever 1b are integrally formed. The inner end of the cantilever 1b extends radially inward into the interior of the main body 1a, forming a partition 1c. The partition 1c is also a tubular structure, with one side serving as the top wall of the main body 1a and separating the internal space of the main body 1a from the internal space of the cantilever 1b. The internal space of the cantilever 1b is used to accommodate the power module 5, which includes a battery or a power module 5 adapter, to power the camera assembly 3 and other functional modules. The lower opening of the main body 1a is connected to the camera assembly 3 via a steering bracket 2. The steering bracket 2 is fixedly connected to the lower end of the main body 1a by bolts or other fasteners, ensuring that the camera assembly 3 can rotate flexibly relative to the fixed base 1 to adjust the monitoring angle.

[0031] Furthermore, combined Figure 2 As shown, a bearing seat 1d is provided on the surface of the partition 1c. The bearing seat 1d is a circular protrusion structure, integrally formed on the upper surface of the partition 1c. The bearing seat 1d is used to install a horizontal bearing 10, which is a ball bearing or a sliding bearing, and is located between the fixed seat 1 and the steering bracket 2, specifically between the rotation center of the steering bracket 2 and the partition 1c. The horizontal bearing 10 is connected to the bearing seat 1d and the steering bracket 2 through its inner ring and outer ring respectively. The inner ring is fixed to the bearing seat 1d, and the outer ring is connected to the rotation axis of the steering bracket 2, thereby achieving low-friction rotation of the steering bracket 2 relative to the fixed seat 1. The horizontal bearing 10 reduces rotational resistance, ensures smooth rotation of the steering bracket 2, and improves the accuracy of camera angle adjustment.

[0032] Furthermore, the bearing housing 1d has a central hole 1e at its center.

The functional component 6 interacts with the outside world through the opening 1g, collecting sound and light information from the environment and / or emitting sound and light signals outward.

[0037] Furthermore, combining Figure 2-3 As shown, in this embodiment, functional component 6 is a speaker, combined with... Figure 10-11 As shown, in another embodiment, functional component 6 is a camera + fill light, with the fill light located on both sides of the camera. Preferably, the camera has infrared imaging function.

[0038] Combination Figure 1-3As shown, another embodiment discloses a camera, including a steering bracket 2, a camera assembly 3, and a PTZ camera mounting base 1 as described in this embodiment.

The horizontal gear 9 is a circular gear made of metal or high-strength plastic and is fixedly connected to the rotation shaft of the steering bracket 2 by a keyway or bolts. A drive gear is fixedly connected to the output shaft of the motor 8, and the drive gear meshes with the horizontal gear 9. The motor 8 drives the horizontal gear 9 to rotate via the drive gear, thereby driving the steering bracket 2 to rotate horizontally relative to the mounting base 1.

[0040] Furthermore, the outer diameter of the top cover 2a of the steering bracket 2 is smaller than the inner diameter of the main body 1a of the fixed seat 1.

[0041] The camera operates as follows: Camera assembly 3 is mounted on the lower opening of the main body 1a of the fixed base 1 via a steering bracket 2. The fixed base 1 is mounted on the connecting base 4 via a cantilever 1b. Power module 5 is installed inside the cantilever 1b, isolated and protected by a partition 1c, and supplies power to camera assembly 3 and functional component 6 via wiring through the central hole 1e. Motor 8 drives horizontal gear 9, rotating the steering bracket 2 to adjust the horizontal viewing angle of camera assembly 3. Functional component 6 collects ambient sound and light information through an opening 1g in the side wall of the main body 1a, and / or emits sound and light signals, supporting intelligent monitoring functions. Antenna is installed inside the convex bulge 1f at the upper end of the main body 1a to optimize signal reception and ensure stable remote communication.
