Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle-mounted equipment technology. Specifically, it relates to a dashcam. Background Technology
[0002] A dashcam records images and sound information of a vehicle in real time. The stability of the dashcam's structure is crucial. Current technologies that allow adjustable shooting angles typically use a hinge connection. The stability of a hinge connection relies on the pressure provided by the screws at the hinge point. The hinge point experiences significant stress, requiring a certain level of material strength. Furthermore, if the screws loosen, the hinge pressure and friction cannot be guaranteed, leading to loosening and angle changes. Another option is to achieve adjustment through a rotating base. Compared to a hinge structure, this structure significantly increases the connection area and ensures stability. However, during manufacturing, if the gap between the main body and the base is too small, the rotational resistance is high, making assembly and adjustment inconvenient. If the gap is too large, the main body is prone to loosening, compromising the stability of the shooting angle. This requires high manufacturing precision. Utility Model Content
[0003] Therefore, the technical problem to be solved by this utility model is to provide a dashcam that can achieve 360° angle adjustment while ensuring the stability of the shooting angle and reducing the difficulty of manufacturing.
[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a dashcam, comprising a main body, a connecting bracket, and a base; a rotating mounting part of the main body is inserted into and rotatably mounted in the mounting cylinder of the connecting bracket; a stabilizing component is provided between the surface of the rotating mounting part and the inner wall of the mounting cylinder, the stabilizing component creating an annular gap between the surface of the rotating mounting part and the inner wall of the mounting cylinder; a damping component is provided between the rotating mounting part and the mounting cylinder to increase rotational resistance; the base is fixedly mounted in the vehicle body, and the connecting bracket is detachably fixed to the base; a camera is mounted on the part of the main body outside the connecting bracket; the shooting angle of the camera is adjusted when the main body rotates relative to the connecting bracket.
[0005] In the aforementioned dashcam, the axial length of the stabilizing component on the rotating mounting portion is less than the axial length of the rotating mounting portion.
[0006] In the aforementioned dashcam, at least two stabilizing components are provided on the rotating mounting portion, and the damping component is located between the two stabilizing components.
[0007] In the aforementioned dashcam, the stabilizing component is a support ring. The support ring is provided on the rotating mounting part near both ends in a circumferential direction, and the outer ring surface of the support ring is in contact with the inner wall surface of the mounting cylinder.
[0008] In the aforementioned dashcam, in the direction in which the rotating mounting part is inserted into the mounting cylinder, the outer edge of the front side of the support ring at the front end is provided with a chamfer.
[0009] In the aforementioned dashcam, an annular mounting groove is provided in the center of the surface of the rotating mounting part, and the damping component includes a silicone ring, which is installed in the annular mounting groove and protrudes from the surface of the rotating mounting part.
[0010] In the aforementioned dashcam, the surface of the silicone ring is provided with silicone protrusions, and the outer ring surface of the silicone protrusions is in close contact with the inner wall surface of the mounting cylinder.
[0011] In the aforementioned dashcam, the outer edges of both sides of the silicone protrusion are chamfered; the thickness of the silicone ring gradually decreases from the position of the silicone protrusion to the end.
[0012] In the aforementioned dashcam, an annular groove is provided on the edge of the first end face of the rotating mounting part, a convex ring is provided inside the mounting cylinder, and a limiting platform with a diameter larger than the outer diameter of the rotating mounting part is provided on the second end of the main body at the location of the rotating mounting part. When the rotating mounting part is inserted into the mounting cylinder: one end of the mounting cylinder is in contact with the surface of the limiting platform, the convex ring enters the annular groove, and an end cap is provided on the other side of the convex ring inside the mounting cylinder, the end cap being fixed to the first end face of the rotating mounting part; the main body has inwardly recessed surfaces on both sides of the portion outside the connecting bracket. One of the recessed surfaces has a camera mounting cavity formed therein, and the camera is installed in the camera mounting cavity. The main body also has a motherboard support block, a motherboard positioning pin, and a motherboard fixing hole. The edge of the motherboard is supported on the motherboard support block, the motherboard positioning pin is inserted into the positioning hole on the motherboard, and the motherboard is fixed to the motherboard fixing hole by screws. The end face of the main body opposite to the mounting cylinder has a concave surface, and a control button is provided on the concave surface. The control button is lower than the end face of the main body and is electrically connected to the motherboard. The main body has a memory card slot that is communicatively connected to the motherboard.
[0013] The aforementioned dashcam includes a connecting bracket comprising a connecting plate, hooks at each of the four corners of the connecting plate, a slot in the middle of the connecting plate, connecting slots corresponding to the hooks at the four corners of the base, and elastic blocks corresponding to the slots in the middle of the base. The hooks are inserted into the connecting slots and hook onto the connecting slots, and the elastic blocks are engaged in the slots.
[0014] The technical solution of this utility model has achieved the following beneficial technical effects: By using a stabilizing component in the form of a support ring, a gap is created between the rotating mounting part and the mounting cylinder, meaning that the two do not directly contact each other. This eliminates the need for surface finishing, allowing only the support ring to be finished. This reduces machining accuracy and cost while ensuring a good support connection effect.
[0015] After the support ring and the mounting cylinder are assembled, they form a multi-circular support effect without changing the support effect. The processing difficulty is reduced. During assembly, due to the reduced contact area, the rotating mounting part can be easily inserted into the mounting cylinder. The design of the silicone ring and silicone protrusions can effectively fill the gap between the rotating mounting part and the mounting cylinder, making the two more tightly connected. When subjected to external force, there will be no rotation, shaking or abnormal noise, thus maintaining stability. Furthermore, during adjustment, due to the existence of a certain amount of damping, the adjustment feel is improved, and there will be no excessive rotation or shaking, enabling fine adjustment.

Detailed Implementation
[0018] One type of dashcam in this embodiment, such as Figure 1 As shown, it includes a main body 1, a connecting bracket 2, and a base 3, as follows: Figure 3 , Figure 5 As shown, the rotating mounting part 1-1 of the main body 1 is inserted into and rotatably mounted in the mounting cylinder 2-1 of the connecting bracket 2. A stabilizing component is provided between the surface of the rotating mounting part 1-1 and the inner wall of the mounting cylinder 2-1, and the stabilizing component is supported between the two, so that there is an annular gap between the surface of the rotating mounting part 1-1 and the inner wall of the mounting cylinder 2-1. A damping component for increasing rotational resistance is provided in the annular gap between the rotating mounting part 1-1 and the mounting cylinder 2-1. The base 3 is fixedly mounted in the vehicle body, and the connecting bracket 2 is detachably fixed on the base 3. A camera 4 is provided on the part of the main body 1 other than the connecting bracket 2. The shooting angle of the camera 4 is adjusted when the main body 1 rotates relative to the connecting bracket 2.
[0019] Subject 1 in this implementation, such as Figure 7-8 As shown, the outer shell includes a front housing 1b and a rear housing 1a. The front housing 1b and the rear housing 1a are fastened and connected together using a pre-existing latch 13 and a hook 14 to form a complete outer shell. Figure 3 As shown, the front housing 1b and the rear housing 1a are symmetrically provided with inwardly tapering surfaces 15 in the area outside the mounting cylinder 2-1. The inwardly tapering surfaces 15 have textured surfaces, which serve two purposes: firstly, to prevent reflections from affecting the shooting process, and secondly, to facilitate angle adjustment. For example... Figure 3 As shown, after the front housing 1b and the rear housing 1a are fastened together, a positioning pin 1-6 and a positioning slot 1-7 are provided on one end of the adjacent rotating mounting part 1-1. The end cover 5 is provided with a positioning hole 5-1 that matches the positioning pin 1-6. The positioning pin 1-6 is inserted into the positioning hole 5-1, and the insertion plate 5-2 that matches the positioning slot 1-7 is inserted into the positioning slot 1-7. The end cover 5 is used to reinforce the front housing 1b and the rear housing 1a.
[0020] like Figure 8 As shown, an end panel 11 is formed on the end of the front housing 1b away from the connecting bracket 2. The outer wall of the end panel 11 is a concave surface 12, and a control button is provided on the concave surface 12. The control button is lower than the end face of the main body 1 and is electrically connected to the motherboard to prevent accidental touch. The front housing 1b also has a camera mounting cavity 6, a speaker mounting cavity 7, and a motherboard mounting and fixing structure. The camera 4 is installed in the camera mounting cavity 6. The motherboard mounting and fixing structure includes a motherboard support block 8, a motherboard positioning pin 9, and a motherboard fixing hole 10. The edge support of the motherboard is placed on the motherboard support block 8, the motherboard positioning pin 9 is inserted into the positioning hole on the motherboard, and the motherboard is fixed to the motherboard fixing hole 10 by screws. Figure 7 As shown, the rear housing 1a is provided with a memory card slot that communicates with the motherboard; when the front housing 1b and the rear housing 1a are fastened together, the end panel 11 enters the rear housing 1a and the rear housing 1a is connected to the end panel 11 by a buckle, while the front housing 1b and the rear housing 1a are axially constrained by the mounting cylinder 2-1 after entering the mounting cylinder 2-1, which achieves a fixing effect.
[0021] like Figure 3 As shown, the axial length of the stabilizing component on the rotary mounting part 1-1 is less than the axial length of the rotary mounting part 1-1. At least two stabilizing components are provided on the rotary mounting part 1-1, and the damping component is located between the two stabilizing components. In this embodiment, the stabilizing component is a support ring 1-4, which is integrally formed on the rotary mounting part 1-1. The support ring 1-4 is provided on the rotary mounting part 1-1 near both ends, protruding circumferentially. The outer ring surface of the support ring 1-4 is in contact with the inner wall surface of the mounting cylinder 2-1. In other embodiments, the support ring 1-4 can also be formed on the mounting cylinder 2-1, with the same effect, but the processing difficulty increases. The support ring 1-4 can also be processed separately and then combined together. The damping component is a silicone ring 1-2. An annular mounting groove is opened in the middle of the surface of the rotating mounting part 1-1. The silicone ring 1-2 is installed in the annular mounting groove. The silicone ring 1-2 protrudes from the surface of the rotating mounting part 1-1, which increases the friction. At the same time, a silicone protrusion 1-3 is also provided on the surface of the silicone ring 1-2. The outer ring surface of the silicone protrusion 1-3 is tightly fitted with the inner wall surface of the mounting cylinder 2-1.
[0022] like Figure 3 As shown, in order to facilitate the insertion of the rotating mounting part 1-1 into the mounting cylinder 2-1, in the direction in which the rotating mounting part 1-1 is inserted into the mounting cylinder 2-1: the outer edge of the front side of the support ring 1-4 located at the front end is provided with a chamfer; the outer edges of both sides of the silicone protrusion 1-3 are provided with chamfers; the thickness of the silicone ring 1-2 gradually decreases from the position of the silicone protrusion 1-3 to the end.
[0023] like Figure 3-5 As shown, an annular groove 1-8 is provided on the edge of the first end face of the rotating mounting part 1-1, a protruding ring 2-2 is provided inside the mounting cylinder 2-1, and a limiting platform 1-5 with a diameter larger than the outer diameter of the rotating mounting part 1-1 is provided on the second end of the main body 1. Figure 2 As shown, when the rotating mounting part 1-1 is inserted into the mounting cylinder 2-1: one end of the mounting cylinder 2-1 is in contact with the surface of the limiting platform 1-5, the convex ring 2-2 enters the annular groove 1-8, and an end cap 5 is provided inside the mounting cylinder 2-1 on the other side of the convex ring 2-2. The end cap 5 is fixed to the first end face of the rotating mounting part 1-1.
[0024] like Figure 5 , Figure 6 As shown, the connecting bracket 2 includes a connecting plate 2-3. Hooks 2-4 are provided at each of the four corners of the connecting plate 2-3. A slot 2-5 is provided in the middle of the connecting plate 2-3. Connecting grooves 3-1 corresponding to the hooks 2-4 are provided at the four corners of the base 3. An elastic block 3-2 corresponding to the slot 2-5 is provided in the middle of the base 3. The hooks 2-4 are inserted into and hooked into the connecting grooves 3-1, and the elastic block 3-2 is engaged in the slots 2-5. One side of the base 3 is a fixing surface, which is attached to the vehicle body using double-sided tape, etc. The other side is a connecting surface, featuring a mesh-like perforated design.
[0025] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of the claims of this patent application.
