Description

Technical Field

[0001] The utility model relates to the technical field of automobile sensor installation, in particular to a metal frame with good stability. Background Art

[0002] The security camera is an acquisition device used for security video surveillance, which converts light images on the image sensor target surface from visible light to near-infrared spectrum into video image signals. During use, the security camera needs to be kept level on the metal frame because the car will shake at different angles while driving.

[0003] Patent application number CN202021106868.7 discloses a stability automobile sensor, including a sensor body and a connector, the connector including a male plug-in and a female plug-in that are plugged into each other, a wire is connected between the male plug-in and the sensor body, a locking column is provided on the side wall of the male plug-in at one end away from the wire, and two locking plates are provided in parallel on the inner side wall of the female plug-in, and a gap for the locking column to be embedded is formed between the end faces of the two locking plates away from the male plug-in and the inner wall of the female plug-in away from its opening, and the distance between the two locking plates is less than the diameter of the locking column. The utility model has the following advantages and effects: by providing a locking plate and a locking column used in conjunction with the locking plate, the maximum active position of the male plug-in in the female plug-in is limited, thereby preventing the male plug-in from being separated from the female plug-in under the action of external force, which has the advantage of preventing the connector from falling off.

[0004] This patent can indeed stably install the sensor on the car through the locking plate; however, the sensor may shift in angle when vibrating; and the shock absorption effect is poor, causing the car to shake and tremble continuously.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0007] In order to achieve the purpose of the utility model, the following technical scheme is adopted: a metal frame with good stability, comprising: a mounting seat, a shockproof mechanism for shockproofing the mounting seat, and a leveling mechanism for keeping the mounting seat installed on the metal frame horizontal when shaking;

[0008] The horizontal mechanism is composed of a bearing plate, a double-ended hinged rod, and a bottom plate; hinged parts are respectively installed on the bearing plate and the bottom plate; the hinged part of the bearing plate is connected to the hinge pin of the bottom plate through the double-ended hinged rod.

[0009] Furthermore, a slide groove is provided on the bottom plate; the hinge on the bottom plate is slidably installed in the slide groove; a return spring is fixedly installed at one end of the hinge; and the other end of the return spring is fixed to the inner wall of the slide groove in the sliding direction of the hinge.

[0010] Furthermore, a limiting rod is provided in the middle sleeve of the return spring; one end of the limiting rod is fixedly connected to the hinge; the other end of the limiting rod passes through the inner wall of the slide groove in the sliding direction of the hinge; and the limiting rod is slidably connected to the slide groove.

Obviously, the described embodiments are partial embodiments of the utility model, rather than all embodiments.

[0020] In the description of the present utility model, it should be understood that the terms "center", "lateral", "longitudinal", "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present utility model. When a mechanism is referred to as being "fixed to" another mechanism, it may be directly on the other mechanism or there may also be a centered mechanism. When a mechanism is considered to be "connected to" another mechanism, it may be directly connected to the other mechanism or there may be a centered mechanism at the same time. When a mechanism is considered to be "set on" another mechanism, it may be directly set on the other mechanism or there may be a centered mechanism at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0021] like Figures 1 to 3 As shown, the utility model is a metal frame with good stability, comprising: a mounting seat 1, an anti-vibration mechanism 2 for preventing the mounting seat 1 from vibrating, and a horizontal mechanism 3 for keeping the mounting seat 1 mounted on the metal frame horizontal when shaking;

[0022] The horizontal mechanism 3 is composed of a bearing plate 31, a double-headed hinged rod 32, and a base plate 33; hinges 37 are installed on the bearing plate 31 and the base plate 33 respectively; the hinge 37 of the bearing plate 31 is connected with the hinge pin of the base plate 33 through the double-headed hinged rod 32, and a slide groove 34 is provided on the base plate 33; the hinge 37 on the base plate 33 is slidably installed in the slide groove 34; when the bearing plate 31 is subjected to a downward force, the bearing plate 31 pushes the double-headed hinged rod 32; the hinged rod pushes the hinge 37 on the base plate 33 to slide along the slide groove 34, so that a good shock-absorbing effect can be achieved through the expansion and tightening of the double-headed hinged rod 32 during shaking.

[0023] A return spring 35 is fixedly installed at one end of the hinge 37; the other end of the return spring 35 is fixed to the inner wall of the slide groove 34 in the sliding direction of the hinge 37, and the double-headed hinge rod 32 that is stretched open by pressure is pushed back to the original position by the return spring 35; a limit rod 36 is provided in the middle sleeve of the return spring 35; one end of the limit rod 36 is fixedly connected to the hinge 37; the other end of the limit rod 36 passes through the inner wall of the slide groove 34 in the sliding direction of the hinge 37; the limit rod 36 is slidably connected to the inner wall of the slide groove 34, and the limit rod 36 is provided to prevent the spring from dislocating when the compression spring of the hinge 37 slides in the slide groove 34, thereby affecting the shock absorption and leveling effect.

[0024] The anti-vibration mechanism 2 for preventing the mounting seat 1 from vibrating is composed of a fixing rod 21, a shock-absorbing spring 22, and a limit block; the fixing rod 21 passes through the mounting seat 1 and is fixedly installed on the bearing plate 31; the shock-absorbing spring 22 is arranged on the fixing rod 21 passing through the mounting seat 1; the limit block is fixedly installed on the top of the fixing rod 21; the shock-absorbing spring 22 is respectively installed on the upper end of the mounting seat 1 and the lower end of the mounting seat 1. When subjected to vibrations at multiple angles, the fixing rod 21 fixes the mounting seat 1; the mounting seat 1 can only slide on the fixing rod 21, and because the shock-absorbing spring 22 is installed on both sides of the mounting seat 1; the shock-absorbing spring 22 reduces vibration when it is forced to move upward or downward; the limit block is used to prevent the fixing rod 21 from detaching from the mounting seat 1 due to excessive vibration.

[0025] Working principle: The mounting piece is installed on the mounting base 1. When it is subjected to slight vibration, the springs at both ends of the mounting base 1 are shock-absorbing and fixed by multiple fixing rods 21, so that the mounting piece installed on the mounting base 1 remains horizontal; when it is subjected to severe vibration, the spring is compressed downward along the fixing rod 21. Due to the severe shaking, the bearing plate 31 fixedly connected to the fixing rod 21 is subjected to downward pressure. When the bearing plate 31 is subjected to downward force, the bearing plate 31 pushes the double-headed hinged rod 32; the hinged rod pushes the hinge 37 on the bottom plate 33 to slide along the slide groove 34, so that when shaking, the double-headed hinged rod 32 is opened and tightened, which can achieve a good shock-absorbing effect. At the same time, the mounting piece on the mounting base 1 still maintains a horizontal angle and will not shake left and right.

[0026] The standard parts used in the utility model can be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings.
