Description

Technical Field

[0001] This utility model relates to the field of pan-tilt bracket technology, and more specifically, to a pan-tilt mounting structure for a patrol vehicle camera. Background Technology

[0002] The content in this section only provides background information related to this invention and may not constitute prior art.

[0003] Patrol cars are a common type of vehicle in our lives, with a wide range of uses. They are often used for patrolling routes in streets, schools, parks, and residential areas. They are simple in structure, easy to drive, use clean energy, and are easy to maintain, making them an ideal choice for urban management. Most patrol cars are now equipped with multiple modern patrol devices, the most important of which is the camera mounted on the top of the patrol car.

[0004] Chinese patent application publication number CN112389343A discloses a camera pan-tilt mounting structure for patrol vehicles, made of stainless steel. It includes a camera pan-tilt mounting base, a rotating adjustment plate, a support cylinder, a bracket base plate, and mounting screw holes. In actual use, the camera is mounted on the top of the patrol vehicle via the bracket base plate, providing a bracket for mounting the camera on the top of the patrol vehicle. The camera can be mounted through the mounting screw holes.

[0005] However, the aforementioned technologies have the following drawbacks: when the camera needs to be replaced or repaired, workers need to climb onto the roof of the vehicle to disassemble the bracket by removing the bolts, which is a rather cumbersome and inconvenient operation. Utility Model Content

[0006] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a pan-tilt mount structure for a patrol vehicle camera, which can facilitate the disassembly of the bracket, simplify the operation, and improve the work efficiency of the staff.

[0007] The objective of this utility model is achieved through the following technical solution:

[0008] A pan-tilt mount structure for a patrol vehicle camera includes a mounting base with a horizontally oriented groove. One end of the groove is open. A slider is slidably disposed within the groove. A mounting plate is fixedly disposed on the top of the slider. A pan-tilt mount support is fixedly disposed on the top of the mounting plate. A limiting member is provided on the mounting base to limit the position of the slider within the groove.

[0009] By adopting the above technical solution, in actual use, when it is necessary to disassemble the camera pan-tilt unit, firstly, the limiting component restricts the position of the slider in the slide groove. Then, the slider can be driven to move away from the slide groove through the opening at one end of the slide groove, thereby removing the mounting plate from the mounting base and completing the disassembly of the camera pan-tilt unit. The operation is simple, convenient and quick, which can effectively improve the work efficiency of the staff.

[0010] In some possible embodiments, the limiting member is configured as a limiting pin, and an installation hole is provided on the side wall of the slider. The limiting member is slidably disposed in the installation hole. A limiting hole for insertion of the limiting member is provided on the side wall of the slide groove. A first elastic member is provided in the installation hole. The first elastic member acts on the limiting member to move the limiting member away from the installation hole. A driving member is provided on the mounting base. The driving member is used to drive the limiting member to disengage from the limiting hole.

[0011] By adopting the above technical solution, when installing the mounting plate, the slider is driven to slide into the slide groove through the side opening of the slide groove, thereby driving the limiting member to move. When the mounting hole and the limiting hole coincide, the limiting member can be inserted into the limiting hole under the action of the first elastic member. At this time, the position of the slider in the slide groove can be limited. When it is necessary to disassemble the mounting plate, the limiting member is driven to disengage from the limiting hole by the driving member, thereby releasing the limitation of the slider's position in the slide groove. The operation is simple and convenient.

[0012] In some possible embodiments, the driving member is configured as a push rod, which is slidably disposed within the limiting hole along the axial direction of the limiting hole. The end of the driving member is used to abut against the limiting member. A strip-shaped hole is provided on the top of the mounting base along the axial direction of the limiting hole. The strip-shaped hole is connected to the limiting hole. A strip-shaped block is slidably disposed within the strip-shaped hole. One end of the strip-shaped block is fixedly connected to the driving member, and the other end extends out of the strip-shaped hole.

[0013] By adopting the above technical solution, the strip block is moved within the strip hole, which in turn drives the driving component to move toward the limiting component within the limiting hole, thereby pushing the limiting component away from the limiting hole. At this point, the limitation imposed by the limiting component on the position of the slider within the slider can be released.

[0014] In some possible embodiments, a paddle is fixedly provided on the side wall of the strip block, and a slot is provided on the side wall of the strip hole away from the paddle. There are two slots, which are located at both ends of the strip hole along the length of the strip hole. The slots are used for the strip block to be inserted.

[0015] By adopting the above technical solution, when installing the mounting plate, the deflector is driven to deflect the strip block into the slot at the end away from the mounting hole. At this time, the driving component is completely located in the limiting hole, and the end of the driving component near the opening of the limiting hole is a certain distance away from the opening of the limiting hole, so that the end of the limiting component can be locked into the limiting hole to limit the position of the slider in the slide groove. At this time, the mounting plate can be installed. When it is necessary to remove the mounting plate, the deflector is driven to deflect the strip block, which first disengages from the slot. Then, the strip block is pushed to move the driving component, causing the driving component to push away from the limiting component. Then, the deflector is deflected to lock the strip block into the slot at the end near the mounting hole. At this time, the limiting component is completely pushed away from the limiting hole, which makes it easier for the operator to move the mounting plate on the mounting base, further facilitating the operator's operation.

[0016] In some possible embodiments, a second elastic element is provided in the limiting hole. The second elastic element acts on the driving element to move the driving element away from the limiting hole. The second elastic element is configured as a compression spring, with one end abutting against the driving element and the other end abutting against the inner wall of the limiting hole.

[0017] In some possible embodiments, the end of the limiting member away from the mounting hole is configured as a bevel, which is used to abut against an opening on one side of the groove.

[0018] By adopting the above technical solution, when installing the mounting plate, the slider is aligned with the opening of the slide groove, and then the inclined surface of the limiting member abuts against the opening of the slide groove. As the slider slides into the slide groove, the limiting member enters the mounting hole under the pressure of the slide groove opening. At this time, the first elastic member is compressed and generates elastic force. When the mounting hole and the limiting hole coincide, the limiting member can be inserted into the limiting hole under the action of the first elastic member. During the installation process, there is no need for the staff to manually press the limiting member, making the operation more convenient and faster.

[0019] In some possible embodiments, an abutment plate is slidably disposed in the groove at one end away from the groove opening along the length of the groove. The side of the abutment plate near the groove opening is used to abut against the side wall of the slider. A third elastic member is disposed in the groove. One end of the third elastic member is fixedly connected to the side wall of the abutment plate away from the slider, and the other end is fixedly connected to the inner wall of the groove.

[0020] By adopting the above technical solution, when the mounting hole and the limiting hole coincide during the installation of the mounting plate, the end of the slider abuts against the abutment plate and squeezes the third elastic element. At this time, the third elastic element is in a compressed state and acts on the slider through the abutment plate, causing the slider to have a tendency to move away from the slide groove. Meanwhile, the limiting element is inserted into the limiting hole, and the slider acts on the limiting block, which can effectively increase the friction between the side wall of the limiting block and the inner wall of the limiting hole, further reducing the risk of the limiting element disengaging from the limiting hole, and effectively improving the reliability and safety of the device in actual use.

[0021] In some possible embodiments, ball bearings are embedded in the sidewall of the slider, the ball bearings being used to roll into contact with the inner wall of the groove.

[0022] By adopting the above technical solution, the ball bearings transform the sliding friction between the side wall of the slider and the inner wall of the groove into rolling friction, effectively reducing the friction between the slider and the inner wall of the groove, and facilitating the movement of the slider within the groove.

[0023] In some possible embodiments, the groove is formed as a T-groove or a dovetail groove, and the slider is configured as a T-block or dovetail block adapted to the groove.

[0024] In summary, the technical solution of this utility model embodiment has at least the following advantages and beneficial effects:

[0025] 1. The design of using a slider and groove with a limit pin allows the gimbal bracket to be pulled out horizontally when disassembling, eliminating the need to climb the roof to remove the bolts. This effectively improves the convenience of quick assembly and disassembly, simplifies the operation for staff, and significantly reduces maintenance difficulty and safety risks.

[0026] 2. The limit pin has a built-in spring and automatically locks when inserted into the limit hole of the slide groove; the inclined guide design eliminates the need for manual pressing during installation; the top rod linkage paddle slot structure allows for stable release of the limit with a single paddle movement, preventing accidental activation and saving effort.

[0027] 3. The slide groove is equipped with a spring abutment plate, which continuously squeezes the slider to generate a reverse force, increasing the friction between the limit pin and the hole wall, preventing the slider from shifting due to vehicle vibration, and improving the gimbal fixation reliability and image stability.

[0028] 4. The slider is fitted with ball bearings, which transforms sliding into rolling friction. Combined with the T-shaped / dovetail groove anti-detachment design, it achieves smooth movement and precise positioning, making it convenient for operators. It saves time and effort while extending the life of the groove and slider, making it suitable for high-frequency disassembly and assembly scenarios in vehicles. Attached Figure Description

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0036] The following is for reference Figures 1 to 5 The present invention will be described in further detail below.

[0037] Reference Figure 1 and Figure 2 A pan-tilt mount structure for a patrol vehicle camera includes a mounting base 1, a horizontal groove 11 on the mounting base 1, one end of the groove 11 being open, a slider 12 slidingly disposed within the groove 11, a mounting plate 13 fixedly disposed on the top of the slider 12, and a pan-tilt mount support 14 fixedly disposed on the top of the mounting plate 13.

[0038] As one embodiment of this utility model, refer to Figure 3 The slide groove 11 is formed as a T-shaped groove, and the slider 12 is set as a T-shaped block that matches the slide groove 11. As another possible embodiment of the present invention, the slide groove 11 can also be formed as a dovetail groove, and the slider 12 is set as a dovetail block that matches the slide groove 11.

[0039] Reference Figure 3 and Figure 4A limiting member 2 is provided on the mounting base 1 to limit the position of the slider 12 within the slide groove 11. In one embodiment of this utility model, the limiting member 2 is configured as a limiting pin. A mounting hole 21 is provided on the side wall of the slider 12, and the limiting member 2 is slidably disposed within the mounting hole 21. A limiting hole 22 for the insertion of the limiting member 2 is provided on the side wall of the slide groove 11. A first elastic member 23 is provided within the mounting hole 21. The first elastic member acts on the limiting member 2 to move the limiting member 2 away from the mounting hole 21. A driving member 24 is provided on the mounting base 1 to drive the limiting member 2 to disengage from the limiting hole 22.

[0040] Reference Figure 4 In one embodiment of this utility model, the first elastic element 23 is configured as a compression spring. The first elastic element 23 is disposed in the mounting hole 21. One end of the first elastic element 23 is fixedly connected to the inner wall of the mounting hole 21, and the other end is fixedly connected to the limiting element 2.

[0041] When installing the mounting plate 13, the slider 12 is driven to slide into the slide groove 11 through the side opening of the slide groove 11, thereby driving the limiting member 2 to move. When the mounting hole 21 coincides with the limiting hole 22, the limiting member 2 can be inserted into the limiting hole 22 under the action of the first elastic member 23. At this time, the position of the slider 12 in the slide groove 11 can be limited. When it is necessary to disassemble the mounting plate 13, the limiting member 2 is driven to disengage from the limiting hole 22 by the driving member 24, thereby releasing the limitation of the slider 12 in the slide groove 11. The operation is simple and convenient.

[0042] Reference Figure 4 In one embodiment of this utility model, the driving member 24 is configured as a top rod. The driving member 24 is slidably disposed in the limiting hole 22 along the axial direction of the limiting hole 22. The end of the driving member 24 is used to abut against the limiting member 2. A strip hole 25 is provided on the top of the mounting base 1 along the axial direction of the limiting hole 22. The strip hole 25 is connected to the limiting hole 22. A strip block 26 is slidably disposed in the strip hole 25. One end of the strip block 26 is fixedly connected to the driving member 24, and the other end extends out of the strip hole 25.

[0043] By moving the strip block 26 within the strip hole 25, the driving member 24 moves toward the limiting member 2 within the limiting hole 22, thereby pushing the limiting member 2 away from the limiting hole 22. At this point, the limitation of the limiting member 2 on the position of the slider 12 within the slider 12 can be released.

[0044] Reference Figure 4A lever 27 is fixedly installed on the side wall of the strip block 26. A slot 29 is provided on the side wall of the strip hole 25 away from the lever 27. There are two slots 29, which are located at both ends of the strip hole 25 along the length direction of the strip hole 25. The slots 29 are used for the strip block 26 to be inserted.

[0045] Among them, reference Figure 4 As one embodiment of this utility model, a through hole 28 is provided on the paddle 27. When the paddle 27 is rotated, the operator can use their fingers or other tools to pass through the through hole 28 to rotate the paddle 27, thereby causing the strip block 26 to deflect. The operation is simpler and more convenient, and the efficiency of operation is further improved.

[0046] Reference Figure 4 A second elastic element 3 is provided in the limiting hole 22. The second elastic element 3 acts on the driving element 24 to make the driving element 24 move away from the limiting hole 22. As an embodiment of the present invention, the second elastic element 3 is set as a compression spring. One end of the second elastic element 3 abuts against the driving element 24, and the other end abuts against the inner wall of the limiting hole 22.

[0047] Reference Figure 4 The end of the limiting member 2 away from the mounting hole 21 is set as an inclined surface 4, which is used to abut against the opening on one side of the slide groove 11. During installation, the inclined surface 4 abuts against the groove opening of the slide groove 11. During the movement of the slider 12, the limiting member 2 is pressed into the mounting hole 21 under the action of the inclined surface 4, which further simplifies the operation of the operator.

[0048] Reference Figure 5 An abutment plate 5 is slidably disposed along the length of the slide groove 11 at one end away from the opening of the slide groove 11. The shape of the abutment plate 5 matches the cross section of the slide groove 11. The side of the abutment plate 5 near the opening of the slide groove 11 is used to abut against the side wall of the slider 12. A third elastic member 51 is disposed in the slide groove 11. One end of the third elastic member 51 is fixedly connected to the side wall of the abutment plate 5 away from the slider 12, and the other end is fixedly connected to the inner wall of the slide groove 11. When the mounting plate 13 is installed, when the mounting hole 21 coincides with the limiting hole 22, the end of the slider 12 abuts against the abutment plate 5 and squeezes the third elastic member 51. At this time, the third elastic member 51 is in a compressed state and acts on the slider 12 through the abutment plate 5, so that the slider 12 has a tendency to move away from the slide groove 11. At this time, the limiting member 2 is inserted into the limiting hole 22, and the slider 12 acts on the limiting block, which can effectively increase the friction between the side wall of the limiting block and the inner wall of the limiting hole 22, further reducing the risk of the limiting member 2 disengaging from the limiting hole 22, and effectively improving the reliability and safety of the device in actual use.

[0049] Reference Figure 5 As one embodiment of this utility model, two third elastic elements 51 are provided, and the third elastic element 51 is configured as a compression spring.

[0050] In one embodiment of this utility model, a ball bearing (not shown in the figure) is embedded in the side wall of the slider 12. The ball bearing is used to make rolling contact with the inner wall of the groove 11. The ball bearing transforms the sliding friction between the side wall of the slider 12 and the inner wall of the groove 11 into rolling friction, effectively reducing the friction between the slider 12 and the inner wall of the groove 11, and facilitating the movement of the slider 12 within the groove 11.

[0051] The implementation principle of the pan-tilt-zoom mounting structure for a patrol vehicle camera proposed in this embodiment is as follows:

[0052] During installation, the slider 12 is aligned with the opening of the groove 11 on the mounting base 1 and pushed horizontally. During the pushing process, the inclined surface 4 of the upper limit pin on the side wall of the slider 12 will contact the edge of the opening of the groove 11 and be subjected to force, forcing the limit pin to overcome the elastic force of the first elastic element 23 and retract into the mounting hole 21. When the slider 12 is fully pushed into place, that is, when the mounting hole 21 on its side wall is precisely aligned with the limiting hole 22 on the side wall of the slide groove 11, the limiting pin automatically pops out under the elastic force of the first elastic element 23 and inserts into the limiting hole 22, realizing the initial mechanical locking of the slider 12. At this time, the end of the slider 12 will press against the abutment plate 5 in the slide groove 11 away from the opening end, compressing the third elastic element 51 behind the abutment plate 5. The reaction force of the third elastic element 51 is continuously applied to the slider 12, making it tend to move towards the opening of the slide groove 11. However, this tendency is blocked by the limiting pin that has been inserted into the limiting hole 22. This pre-tightening force significantly increases the static friction between the side of the limiting pin and the inner wall of the limiting hole 22, forming a secondary locking effect.

[0053] During disassembly, the operator moves the lever 27 located on top of the mounting base 1, causing the strip block 26 connected to it to disengage from its current location (away from the opening end of the slide groove 11) in the slot 29 and slide along the strip hole 25 towards the opening end of the slide groove 11. The strip block 26 drives the drive component 24 fixedly connected to it to move towards the limiting pin in the limiting hole 22. The end of the push rod presses against the limiting pin, overcoming the elastic force of the first elastic element 23, and completely pushes the limiting pin away from the limiting hole 22 on the slide groove 11, retracting it into the mounting hole 21 of the slider 12. At this time, the operator rotates the lever 27 to make the strip block 26 engage in the slot 29 near the opening end of the slide groove 11 (in this position, the push rod remains in a pressing state against the limiting pin). After unlocking, with the assistance of the pre-tightening force of the third elastic element 51, the operator can easily pull the slider 12, together with the mounting plate 13 and the gimbal support 14, horizontally out along the slide groove 11 to complete the disassembly.

[0054] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
