Description

Technical Field

[0001] This utility model relates to the technical field of dashcam accessories, and in particular to a quick-release mounting bracket for dashcams. Background Technology

[0002] With the increase in car ownership, dashcams, as important in-vehicle electronic devices for recording driving images and assisting in accident identification, have become widely popular. In order to facilitate installation and removal, a large number of quick-mount brackets for fixing dashcams to the windshield of vehicles have appeared on the market.

[0003] Existing quick-release mounting brackets typically have a simple clamping structure design, mostly using a spring-driven single-sided movable clamping arm or a dual-sided independent clamping arm structure. When installing a dashcam, users often need to manually open one side of the clamping arm, insert one side of the dashcam, and then release their hand to allow the clamping arm to spring back and clamp, or they need to adjust the position of the two clamping arms separately.

[0004] However, this asynchronous clamping method has obvious shortcomings in actual operation. Since the clamping arms do not move synchronously, it is difficult for the dashcam to be accurately placed in the center of the bracket at the moment of clamping. Positional deviation often occurs, resulting in uneven clamping force. Users need to manually fine-tune it a second time to move the dashcam to the center position between the clamping arms, which increases the complexity of the operation.

[0005] Therefore, this utility model proposes a quick-release mounting bracket for dashcams to address the shortcomings of existing technologies. Summary of the Invention

[0006] In view of the problems of cumbersome operation of the clamping mechanism and inability to achieve synchronous centering clamping in the existing quick-release mounting bracket for dash cams, which result in low installation efficiency, this utility model aims to provide a quick-release mounting bracket for dash cams with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a quick-release mounting bracket for a dashcam, including an adjustment mechanism and a quick-release mechanism fixedly connected to the adjustment mechanism via a connecting plate. The quick-release mechanism includes a protective shell and two slidably disposed on both sides of the protective shell, as well as a rotating shaft, a gear, two upper and lower racks, two connecting rods, two third springs, and a handle disposed within the quick-release mechanism.

[0008] The rotating shaft is rotatably housed within the protective shell, and the gear is fixedly connected to the rotating shaft, forming the core of the transmission. The upper and lower racks mesh with the gear in opposite directions, forming a linkage mechanism that can convert rotational motion into bidirectional linear motion. One end of each of the two connecting rods is fixedly connected to the two racks, and the other end is fixedly connected to the two clamping plates, forming a force transmission path from the racks to the clamping plates.

[0009] Furthermore, one end of each of the two third springs is fixedly connected to the two racks, and the other end is fixedly connected to the protective shell. The handle is fixedly connected to the rotating shaft and extends out of the protective shell. This combination allows the operator to drive the two clamps to retract inward or open outward simultaneously through the precise linkage of the gears and racks when turning the handle, thus achieving a fast, centered, and stable clamping action.

[0010] Preferably, the quick-release mechanism further includes a component for providing bottom support, which includes a hollow column fixedly connected to the lower part of the protective shell in a vertical direction, a solid column slidably connected inside the hollow column, a support plate fixedly connected to the bottom end of the solid column, and a second spring sleeved on the outside of the solid column, with its two ends abutting against the inner bottom wall of the hollow column and the top of the solid column, respectively. This structure can provide elastically liftable bottom support.

[0011] Preferably, in the assembled state, the support plate is located between the two clamping plates, so that it can work together with the two clamping plates to form a three-point stable clamping structure consisting of the bottom and the sides, which is used to clamp the dashcam and enhances the stability of the clamping.

[0012] Preferably, the adjustment mechanism includes a housing and a driven rotating plate fixedly connected to the connecting plate. The inner wall of the housing has multiple grooves, which provide basic positioning points for locking the angle.

[0013] Preferably, the adjustment mechanism further includes a button slidably inserted through the driven rotating plate, a protrusion fixedly connected to the button and facing the inner wall of the housing, the protrusion being used to selectively engage with a groove, and a first spring with one end abutting against the button. This assembly constitutes an angle-adjustable push-to-unlock device.

[0014] Preferably, the adjustment mechanism further includes an active rotating plate coaxially disposed above the driven rotating plate, the active rotating plate being fixedly connected to the connecting plate, and a rotating plate rotatably housed within the housing and fixedly connected to the top of the active rotating plate.

[0015] Preferably, the other end of the first spring is fixedly connected to the rotating plate, so that the first spring forms an elastic connection and support between the button and the rotating plate, ensuring reliable reset of the unlocking and locking actions.

[0016] Preferably, in order to install the entire bracket on the vehicle, the bracket also includes a suction cup and a bent rod, one end of which is fixedly connected to the suction cup and the other end of which is fixedly connected to the housing of the adjustment mechanism, forming a complete mounting base.

[0017] This utility model has the following beneficial effects: 1. This utility model, by setting up a clamping assembly consisting of a handle, gears, double racks and a return spring, achieves the synchronous opening and automatic closing of the clamping plates on both sides, solving the problems of cumbersome operation of the dashcam bracket clamping and unstable clamping caused by uneven force on both sides of the clamping plates in the prior art. It achieves the technical effect of labor-saving and quick clamping process, accurate positioning and stable and reliable operation.

[0018] 2. This utility model, by setting an adjustment mechanism with a press-type unlock button, positioning protrusion and groove, realizes quick unlocking and indexing locking of the angle, which solves the problems of inconvenient operation of bracket angle adjustment and easy deflection due to vehicle vibration after locking in the prior art, and achieves the technical effect of labor-saving angle adjustment, accurate positioning and firm and reliable locking.

[0019] 3. This utility model combines a clamping plate that moves synchronously from left to right with a support plate that extends elastically from top to bottom to form a three-point combined clamping structure. This solves the problem that in the prior art, a bracket that relies solely on one side clamping or bottom support is prone to causing the recorder to loosen or shift under bumpy road conditions. This achieves the technical effect of more comprehensive clamping, more stable fixation, and stronger shock resistance. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please refer to Figures 1 to 4 This utility model provides a quick-release mounting bracket for a dashcam, which aims to solve the problems of cumbersome operation, inability to clamp synchronously, and inconvenient angle adjustment and locking of dashcam brackets in the prior art.

[0024] like Figure 1 As shown, the overall structure of the quick-release mounting bracket for the dashcam includes an adjustment mechanism 3 and a quick-release mechanism 5 fixedly connected to the adjustment mechanism 3 via a connecting plate 4. The adjustment mechanism 3 and the quick-release mechanism 5 together constitute the main body of the bracket for installing and adjusting the dashcam 6. The quick-release mechanism 5 is used to achieve quick installation and fixation of the dashcam 6, and its specific structure is as follows: Figure 3 As shown, the quick-release mechanism 5 includes a protective shell 512 as the supporting base for its internal components. Two clamping plates 505 are slidably disposed on both sides of the protective shell 512 for clamping the recorder 6 from the left and right sides. To achieve synchronous opening and closing of the two clamping plates 505, a transmission assembly consisting of a gear 509 and a rack 507 is provided inside the protective shell 512. This assembly includes a rotating shaft 510 rotatably disposed inside the protective shell 512, a gear 509 fixedly connected to the rotating shaft 510, and an upper... The next two racks 507 are connected to the gear 509 in opposite directions. In order to transmit the linear motion of the racks 507 to the clamps 505, one end of each of the two connecting rods 506 is fixedly connected to the racks 507 and the other end is fixedly connected to the clamps 505. When the operator rotates the rotating shaft 510, the gear 509 will drive the racks 507 to move towards or away from each other, and then drive the clamps 505 to clamp inward or open outward synchronously through the connecting rods 506.

[0025] Furthermore, in order to provide an elastic force for automatic reset of the clamping action, the quick-release mechanism 5 also includes two third springs 508. One end of each third spring 508 is fixedly connected to the rack 507, and the other end is fixedly connected to the protective shell 512. When the clamping plate 505 is pulled outward, the third spring 508 is stretched and stores elastic energy. After release, the third spring 508 rebounds and drives the rack 507 to move inward, thereby realizing the automatic clamping of the clamping plate 505. For ease of operation, the handle 511 is fixedly connected to the rotating shaft 510 and extends out of the protective shell 512. The operator can control the entire clamping and releasing process by rotating the handle 511.

[0026] To further improve the fixation of the recorder 6, in addition to the aforementioned left and right clamping structures, the quick-release mechanism 5 also includes a support assembly for providing bottom support and vertical clamping force. Please refer to [reference needed]. Figure 3 The structure of the support assembly includes a hollow column 501, which is fixedly connected to the lower part of the protective shell 512 in a vertical direction. A solid column 503 is slidably connected to the inside of the hollow column 501. A support plate 504 is fixedly connected to the bottom end of the solid column 503. The support plate 504 is located between two clamping plates 505. When the recorder 6 is installed, the bottom of the recorder 6 is placed on the upper surface of the support plate 504.

[0027] To achieve automatic vertical clamping, a second spring 502 is sleeved on the outside of the solid column 503, with its two ends abutting against the inner bottom wall of the hollow column 501 and the top of the solid column 503, respectively. In its natural state, the second spring 502 pushes the solid column 503 upward to its highest position. When the operator pulls down the support plate 504, the solid column 503 slides downward inside the hollow column 501 and compresses the second spring 502, providing space for placing the recorder 6. After the support plate 504 is released, the compressed second spring 502 rebounds, pushing the solid column 503 and the support plate 504 upward, thereby clamping the recorder 6 from the bottom. This bottom support force provided by the support plate 504, combined with the left and right clamping forces provided by the two clamping plates 505, constitutes a three-point stable clamping structure, ensuring that the recorder 6 is firmly fixed on the quick-release mechanism 5.

[0028] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, in order to achieve adjustment and locking of the entire bracket's shooting angle, the bracket also includes an adjustment mechanism 3, please refer to... Figure 1 , Figure 2 and Figure 4The adjustment mechanism 3 is fixedly connected to the quick-assembly mechanism 5 via the connecting plate 4. Its internal structure mainly includes a housing 301. Multiple grooves 302 for indexing and positioning are provided on the inner wall of the housing 301. The driven rotating plate 308 is fixedly connected to the connecting plate 4. The active rotating plate 307 is also coaxially arranged above the driven rotating plate 308 and fixedly connected to the connecting plate 4, thereby ensuring that the active rotating plate 307 and the driven rotating plate 308 can rotate synchronously with the quick-assembly mechanism 5 below.

[0029] To control the locking and unlocking of the rotation, button 303 is slidably mounted on driven rotating plate 308. Protrusion 304 is fixedly connected to button 303 and faces the inner wall of housing 301. The shape and size of protrusion 304 are adapted to groove 302 for selectively engaging in one of the grooves 302. Rotating plate 306 is rotatably housed in housing 301 and fixedly connected to the top of active rotating plate 307. One end of first spring 305 is fixedly connected to button 303, and the other end is fixedly connected to rotating plate 306. This structure allows protrusion 304 to disengage from groove 302 when button 303 is pressed, thus unlocking, and automatically resetting and locking after being released.

[0030] As another preferred embodiment, for mounting the entire bracket on a surface such as a vehicle window, please refer to... Figure 1 The bracket also includes a suction cup 1 and a bent rod 2. One end of the bent rod 2 is fixedly connected to the suction cup 1, and the other end is fixedly connected to the housing 301 of the adjustment mechanism 3, thus forming a complete bracket structure that can be suction-installed.

[0031] The working principle of this quick-release mounting bracket for a dashcam is as follows: When the recorder 6 needs to be installed, the operator first turns the handle 511 in the quick-release mechanism 5 counterclockwise. The rotation of the handle 511 causes the rotating shaft 510, which is fixedly connected to it, to rotate counterclockwise synchronously with the gear 509. Since the gear 509 is meshed with the upper and lower racks 507, the rotation of the gear 509 will drive the two racks 507 to move outwards respectively. During this process, the third spring 508 connected to the racks 507 is stretched. At the same time, the connecting rod 506, which is fixedly connected to the racks 507, causes the clamps 505 on the left and right sides to open outwards synchronously. Meanwhile, the operator pulls down the support plate 504 at the bottom. The support plate 504 drives the solid column 503, which is fixedly connected to it, to slide downward in the hollow column 501, thereby stretching the second spring 502. After these actions are completed, the recorder 6 can be placed between the upper surface of the support plate 504 and the two clamping plates 505. After releasing the handle 511 and the support plate 504, the stretched third spring 508 will elastically rebound, pulling the rack 507 to move inward, thereby driving the clamping plates 505 to tighten inward. At the same time, the second spring 502 will also elastically rebound, pushing the solid column 503 and the support plate 504 upward. Through the combined force of the left and right sides and the bottom, the recorder 6 is firmly clamped and fixed.

[0032] When the shooting angle needs to be adjusted, the operator presses the button 303 in the adjustment mechanism 3 inward, causing the button 303 to slide inward in the driven rotating plate 308. The button 303 drives the protrusion 304 above it to move inward, disengaging it from the groove 302 on the inner wall of the outer casing 301. At this time, the first spring 305 is compressed, and the entire adjustment mechanism 3 is in the unlocked state. The operator can rotate the connecting plate 4 and the entire quick-release mechanism 5 below it. When the shooting angle is adjusted to a suitable position, the button 303 is released. At this time, the compressed first spring 305 rebounds, pushing the button 303 outward, causing the protrusion 304 to slide back in and engage in another groove 302, thus locking the angle. Finally, the suction cup 1 is attached to the car window glass, completing the entire installation process.

[0033] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
