Description

Technical Field

[0001] This utility model relates to the field of camera equipment technology, and in particular to a position adjustment mechanism and a camera device using the position adjustment mechanism. Background Technology

[0002] Cameras are widely used in security monitoring. To improve lens imaging, a light shield is usually installed at the window glass to reduce stray light interference. However, in actual production and assembly, due to the influence of component processing errors and assembly tolerances, it is often difficult to achieve precise alignment between the lens center and the circular hole on the light shield. This results in partial obstruction of the lens imaging area or a decrease in appearance quality, affecting the overall performance and market competitiveness of the product.

[0003] Several camera position adjustment mechanisms already exist in the prior art. For example, Chinese patent CN215000540U discloses a multi-degree-of-freedom camera adjustment device, which achieves camera adjustment in multiple degrees of freedom through a first rotation adjustment part, a sliding part, and a second rotation adjustment part. This device can meet the adjustment needs of camera position and angle to a certain extent, but its structure is relatively complex. It is mainly aimed at large-scale posture adjustment in industrial visual inspection, and its adjustment resolution and specificity are insufficient for the precise fine-tuning scenarios between the lens and the housing light shield of security monitoring cameras. In addition, this device lacks an effective gap elimination and anti-loosening structure after adjustment, and its position is prone to shift due to vibration during long-term use, affecting the stability of lens alignment.

[0004] On the other hand, in practical applications, in addition to the precise alignment requirements between the lens and the light shield, the overall mounting position of the camera inside the housing also needs to be adaptively adjusted according to different installation environments and usage scenarios. In existing technologies, the overall position adjustment of the camera is usually achieved by replacing the mounting bracket or re-drilling holes, which is cumbersome, has a limited adjustment range, and cannot achieve continuous and precise position adjustment.

[0005] Therefore, there is an urgent need for an adjustment mechanism that can simultaneously achieve coarse adjustment of the overall position of the camera and precise fine adjustment of the lens components, in order to solve the problems of insufficient adjustment accuracy, single adjustment dimension, and easy loosening after adjustment in the existing technology.

[0048] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

However, this utility model 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 utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0049] Combination Figures 1 to 6 The position adjustment mechanism provided by this utility model includes: a camera mounting base 10, a horizontal adjustment component 20, a floating base plate 30, a vertical adjustment rod 40, a vertical guide rod 50, and a base plate 60; wherein, the camera mounting base 10 is disposed on the floating base plate 30; the horizontal adjustment component 20 is disposed on the floating base plate 30 and abuts against the camera mounting base 10, and is used to drive the camera mounting base 10 to move horizontally relative to the floating base plate 30 by adjusting the horizontal adjustment component 20; the floating base plate 30 is disposed above the base plate 60 by the vertical adjustment rod 40 and the vertical guide rod 50; the vertical adjustment rod 40 is rotatably disposed on the base plate 60 and is threadedly engaged with the floating base plate 30, and is used to drive the floating base plate 30 to move vertically relative to the base plate 60 by rotating the vertical adjustment rod 40; the vertical guide rod 50 is disposed on the base plate 60 and is used to guide the vertical movement direction of the floating base plate 30.

[0050] In one optional embodiment of this utility model, such as Figures 1 to 6As shown, the camera mounting base 10 further includes: a camera mounting portion 101, a fixing portion 102, and a fixing screw 103; wherein, the camera mounting portion 101 has a first side surface and a second side surface disposed opposite to each other (i.e., the first side surface of the camera mounting portion 101 is opposite to the second side surface of the camera mounting portion 101), and at least one fixing portion 102 is respectively provided on the first side surface and the second side surface of the camera mounting portion 101; an elongated hole 104 is provided on the fixing portion 102, and the elongated hole 104 extends in a horizontal direction; the fixing screw 103 passes through the elongated hole 104 and is screwed into the floating base plate 30, thereby locking the camera mounting base 10 onto the floating base plate 30, and the length of the elongated hole 104 is greater than the diameter of the fixing screw 103, so that the camera mounting base 10 can move horizontally relative to the floating base plate 30 before the fixing screw 103 is tightened. It should be noted that when the fixing screw 103 passes through the elongated hole 104 and is screwed into the floating base plate 30, the floating base plate 30 is also provided with a corresponding threaded hole 301.

[0051] Specifically, such as Figures 1 to 6 As shown, two fixing parts (i.e., a first fixing part and a second fixing part) are symmetrically arranged at the bottom end of the first side surface of the camera mounting part; the first fixing part has a first elongated hole, and the second fixing part has a second elongated hole; a first fixing screw passes through the first elongated hole and is screwed into the floating substrate, and a second fixing screw passes through the second elongated hole and is screwed into the floating substrate. Two fixing parts (i.e., a third fixing part and a fourth fixing part) are also symmetrically arranged at the bottom end of the second side surface of the camera mounting part; the third fixing part has a third elongated hole, and the fourth fixing part has a fourth elongated hole; a third fixing screw passes through the third elongated hole and is screwed into the floating substrate, and a fourth fixing screw passes through the fourth elongated hole and is screwed into the floating substrate.

[0052] It should be noted that the fixing part provided on the first side surface of the camera mounting part is symmetrical to the fixing part provided on the second side surface of the camera mounting part. In addition, the fixing part 102 can be an integral structure with the camera mounting part 101 or it can be a separate structure. Those skilled in the art can choose flexibly according to actual needs, and there is no limitation here.

[0053] In one optional embodiment of this utility model, such as Figures 1 to 6As shown, the horizontal adjustment assembly 20 further includes: a first connector 201, a second connector 202, a first horizontal adjustment screw 203, and a second horizontal adjustment screw 204; wherein, the first connector 201 and the second connector 202 are disposed opposite to each other on the floating base plate 30, and the first connector 201 and the second connector 202 are respectively provided with a first horizontal adjustment hole 205 and a second horizontal adjustment hole 206, the first horizontal adjustment screw 203 passes through the first horizontal adjustment hole 205 and abuts against the camera mounting base 10, and the second horizontal adjustment screw 204 passes through the second horizontal adjustment hole 206 and abuts against the camera mounting base 10; by adjusting the depth to which the first horizontal adjustment screw 203 and the second horizontal adjustment screw 204 are screwed into the corresponding first horizontal adjustment hole 205 and the second horizontal adjustment hole 206, the horizontal position of the camera mounting base 10 can be adjusted.

[0054] The first connector 201 and the second connector 202 can be integrated with the floating substrate 30 or be separate structures. Those skilled in the art can choose flexibly according to actual needs, and no limitation is made here.

[0055] In this invention, the horizontal position of the camera mounting base 10 can be adjusted by adjusting the depth to which the first horizontal adjusting screw 203 and the second horizontal adjusting screw 204 are screwed into the corresponding first horizontal adjusting holes 205 and 206. Specifically, when the depth to which the first horizontal adjusting screw 203 is screwed into the first horizontal adjusting hole 205 is greater than the depth to which the second horizontal adjusting screw 204 is screwed into the second horizontal adjusting hole 206, the camera mounting base 10 moves horizontally towards the second connector 202 because the first and second side surfaces of the camera mounting base 10 respectively abut against the screwed-in first horizontal adjusting screw 203 and the second horizontal adjusting screw 204; when the depth to which the first horizontal adjusting screw 203 is screwed into the first horizontal adjusting hole 205 is less than the depth to which the second horizontal adjusting screw 204 is screwed into the second horizontal adjusting hole 206, the camera mounting base 10 moves horizontally towards the first connector 201 because the first and second side surfaces of the camera mounting base 10 respectively abut against the screwed-in first horizontal adjusting screw 203 and the second horizontal adjusting screw 204.

[0056] Furthermore, it should be noted that adjusting the horizontal position of the camera mounting base 10 requires the cooperation of the horizontal adjustment component 20 with the elongated hole 104 on the fixing part 102. The length of the elongated hole 104 limits the horizontal movement range of the camera mounting base 10. Those skilled in the art can flexibly set it according to the actual required horizontal adjustment distance, and this utility model does not make a specific limitation in this regard.

[0057] In this invention, the horizontal position of the camera mounting base is adjusted by the cooperation of the horizontal adjustment component and the elongated hole on the fixing part. The length of the elongated hole determines the horizontal movement range. Those skilled in the art can design flexibly according to actual needs to make the adjustment range adaptable. At the same time, the structure is simple and compact. The adjustment process only requires rotating the first horizontal adjustment screw and the second horizontal adjustment screw. After the position is determined, the fixing screw is tightened. The operation is convenient and effectively improves the installation and calibration efficiency.

[0058] In order to ensure that the first leveling screw 203 and the second leveling screw 204 can be securely screwed into the corresponding first leveling hole 205 and second leveling hole 206, the first connector 201 may also be provided with a first leveling hole extension (not shown in the figure), and the second connector 202 may also be provided with a second leveling hole extension 207; wherein, the first leveling hole extension is coaxially arranged with the first leveling hole 205, and its inner wall is provided with the same thread as the inner wall of the first leveling hole 205; the second leveling hole extension 207 is coaxially arranged with the second leveling hole 206, and its inner wall is provided with the same thread as the inner wall of the second leveling hole 206.

[0059] In one optional embodiment of this utility model, such as Figures 1 to 6 As shown, the floating substrate 30 has at least one vertical adjustment hole 302 and two or more guide holes 303; wherein, the vertical adjustment rod 40 passes through the vertical adjustment hole 302 and is threaded into the inner wall of the vertical adjustment hole 302; the first end of the vertical guide rod 50 is fixedly connected to the base plate 60, and the second end of the vertical guide rod 50 passes through the guide hole 303 to guide the vertical movement direction of the floating substrate 30.

[0060] In a preferred embodiment of this utility model, such as Figures 1 to 6 As shown, the floating base plate 30 has two vertical adjustment holes 302 and four guide holes 303. The two vertical adjustment holes 302 are symmetrically located diagonally on the floating base plate 30, and the four guide holes 303 are located at the four corners of the floating base plate 30, and are symmetrical to each other. The two vertical adjustment holes 302, symmetrically located diagonally on the floating base plate 30, allow for independent adjustment of the height of both sides of the floating base plate 30 by rotating the two vertical adjustment rods 40, achieving precise leveling of the floating base plate 30 and preventing tilting caused by unilateral driving. The four guide holes 303, located at the four corners of the floating base plate 30, cooperate with the vertical guide rods 50 to form a stable rectangular guide frame. Multi-point support enhances structural rigidity, ensuring accurate trajectory and no swaying during lifting and lowering.

[0061] Optionally, such as Figures 1 to 6As shown, in order to ensure that the fixing screw 103 can be firmly screwed into the floating base plate 30 after passing through the elongated hole 104, the floating base plate 30 is also provided with a threaded hole extension 304, wherein the threaded hole extension 304 is coaxially arranged with the threaded hole 301, located at the lower part of the threaded hole 301, and its inner wall is provided with the same thread as the inner wall of the threaded hole 301.

[0062] In one optional embodiment of this utility model, such as Figures 1 to 6 As shown, the vertical adjustment rod 40 has a first thread 401 on its body, which engages with a thread (not shown) on the floating base plate 30. An operating part 402 is provided on the first end of the vertical adjustment rod 40, and the second end of the vertical adjustment rod 40 is rotatably connected to the base plate 60. When the vertical adjustment rod 40 is rotated through the operating part 402, the floating base plate 30 can be driven to move vertically relative to the base plate 60.

[0063] The operating part 402 can be a cross pattern provided on the first end of the vertical adjustment rod 40. Those skilled in the art can flexibly choose the type and shape of the operating part 402 according to actual needs, and there is no limitation here.

[0064] In order to enable the vertical adjustment rod 40 to be rotatably connected to the base plate 60, the second end of the vertical adjustment rod 40 is provided with a circumferential groove 403. The base plate 60 is provided with a mounting hole 601 that mates with the circumferential groove 403. After the vertical adjustment rod 40 passes through the floating base plate 30, its second end is engaged with the base plate 60 through the circumferential groove 403 to achieve axial positioning and relative rotation.

[0065] In one optional embodiment of this utility model, such as Figures 1 to 6 As shown, the position adjustment mechanism further includes a gap locking assembly 70; wherein the gap locking assembly 70 is disposed on the vertical guide rod 50 and is used to eliminate the thread gap of the vertical adjustment rod 40.

[0066] Optionally, the gap locking assembly 70 further includes: a first compression spring 701, a second compression spring 702, and a lock nut 703; wherein, the first compression spring 701 is sleeved on the vertical guide rod 50, located between the floating base plate 30 and the base plate 60, and the first end and the second end of the first compression spring 701 are in contact with the floating base plate 30 and the base plate 60, respectively; the second compression spring 702 is sleeved on the vertical guide rod 50, and the first end of the second compression spring 702 is in contact with the first side surface of the floating base plate 30; the lock nut 703 is threaded to the second end of the vertical guide rod 50 and abuts against the second end of the second compression spring 702.

[0067] This invention achieves bidirectional elastic pre-tightening of the floating substrate in the vertical direction by setting a gap locking component. A first compression spring is sleeved on the vertical guide rod between the floating substrate and the base plate, and a second compression spring is located on the other side of the floating substrate. With the help of an anti-loosening nut, the floating substrate is elastically pre-tightened in the vertical direction. This structure effectively eliminates the transmission gap at the threaded connection of the vertical adjustment rod, ensuring the continuity and stability of vertical adjustment and avoiding adjustment lag or position drift caused by gap. At the same time, the component has a compact structure, is easy to assemble, and combines pre-tightening and locking functions, improving adjustment accuracy and long-term reliability.

[0068] In one optional embodiment of this utility model, such as Figures 1 to 6 As shown, the position adjustment mechanism further includes a vertical locking assembly 80; wherein the vertical locking assembly 80 includes a locking post 801 and a vertical locking screw 802; the locking post 801 is fixed to the floating base plate 30 (the second side surface of the floating base plate 30), and the locking post 801 has a first screw hole (not shown in the figure) along the axial direction, and a second screw hole 803 communicating with the first screw hole is opened on the side surface of the locking post 801; the vertical adjustment rod 40 passes through the first screw hole, and the vertical locking screw 802 is screwed into the second screw hole 803 and abuts against the vertical adjustment rod 40 to lock the floating base plate 30 in the current vertical position. It should be noted that the inner wall of the second screw hole 803 is provided with a thread that matches the vertical locking screw 802.

[0069] In one optional embodiment of this utility model, such as Figures 1 to 6 As shown, the position adjustment mechanism also includes a cable management component 602, which is disposed on the base plate 60 and is used to store and constrain the cable led out from the camera body 200.

[0070] Combination Figures 1 to 8 The present invention also provides a camera device using a position adjustment mechanism, comprising: a position adjustment mechanism 100, a camera body 200, and a housing 300; wherein, the camera body 200 is disposed on the camera mounting base 10 in the position adjustment mechanism 100 for capturing images or videos; the housing 300 is disposed outside the position adjustment mechanism 100 and the camera body 200, and the lens of the camera body 200 is opposite to the lens window of the housing 300.

[0071] The position adjustment mechanism 100 is the position adjustment mechanism provided by this utility model. Regarding the camera body 200, those skilled in the art can select any suitable camera module or customized lens assembly according to the actual application scenario and imaging requirements; this utility model does not specifically limit this selection.

[0072] Optionally, combined Figures 1 to 8The camera device also includes a slide rail 310 and a sliding screw (not shown in the figure); wherein, the slide rail 310 is disposed on the bottom surface inside the housing 300, and the sliding screw passes through the fixing hole 603 provided on the base plate 60 and is slidably disposed in the slide rail 310; when the position adjustment mechanism 100 and the camera body 200 are pushed, the sliding screw slides along the slide rail 310 to adjust the distance between the lens of the camera body 200 and the lens window of the housing 300.

[0073] The number and arrangement of the slide rails 310 can be flexibly selected by those skilled in the art according to actual needs, and are not limited here. Specifically, for example... Figure 7 and Figure 8 As shown, two slide rails 310 are provided on the bottom surface inside the housing 300, and the two slide rails 310 are arranged in parallel relative to each other.

[0074] This utility model provides a position adjustment mechanism and a camera device using the position adjustment mechanism. The camera mounting base is driven to move horizontally relative to a floating base plate via a horizontal adjustment component, and the floating base plate is driven to move vertically relative to a base plate via a vertical adjustment rod. This achieves bidirectional independent adjustment of the camera lens in both horizontal and vertical directions, effectively compensating for processing errors and assembly tolerances, ensuring precise alignment of the lens center with the circular hole of the light-shielding plate, and improving product appearance quality and imaging effect. Simultaneously, by setting a gap locking component, a continuous elastic preload is applied in the vertical direction, eliminating transmission gaps at the threaded connection of the vertical adjustment rod, ensuring the continuity and stability of vertical adjustment. Horizontal locking is achieved through the cooperation of a fixing screw and a long hole, and radial locking of the vertical adjustment rod by the vertical locking component forms a double locking mechanism, ensuring long-term stability of the adjusted position and resisting vibration and external impact. Furthermore, through the cooperation of a slide rail and a sliding screw, the entire camera can slide continuously within the housing, enabling coarse adjustment of the distance between the lens and the lens window, making operation convenient and greatly improving installation and calibration efficiency.
