Description

Technical Field

[0001] The utility model relates to the technical field of hinges, in particular to a hinge assembly and a bracket with the hinge assembly. Background Art

[0002] At present, in order to realize the rotation of the shooting angle of the camera product carried by the camera stand, the following two rotation axis solutions are usually adopted: using a screw and nut matching structure as the bracket rotation axis; or using a damping hinge and locking screw matching structure as the bracket rotation axis. However, when the screw and nut matching structure is used as the bracket rotation axis, the damping force of the bracket will drop sharply as the number of rotations increases, resulting in failure of the shaft and a very short service life. At the same time, the structure is easily affected by the force of the screwdriver head during production, resulting in fluctuations in the damping force of each batch of products, making it difficult to maintain production consistency; and when the bracket rotation axis adopts a damping hinge and locking screw matching structure, the cost is relatively expensive, and the two matching hinges need to be locked on the bracket by locking screws, which means that the bracket needs to have a certain thread depth, which will cause the overall structure of the bracket to be very thick, which is contrary to the mainstream of thin and small bracket products in the market. When using this solution, the damping hinge needs to be controlled as an appearance part for material control, which is easy to introduce adverse factors caused by the hinge, which will cause certain production control difficulties on the production side.

[0022] In order to more fully understand the technical content of the present invention, the technical solution of the present invention is further introduced and illustrated below in conjunction with schematic diagrams, but is not limited thereto.

[0023] Reference Figures 1 to 7 , Figures 1 to 7 A specific embodiment of the bracket 100 of the utility model is shown. In the embodiment shown in the drawings, the bracket 100 includes a bracket body 10 and two hinge assemblies 20, the bracket body 10 includes a main board 11, a pitch plate 12 and a support plate 13, the hinge assembly 20 includes a connecting member 21 and a rotating member 22, the rotating member 22 is sleeved on the outer surface of the connecting member 21 and can rotate relative to the connecting member 21, and the pitch plate 12 and the support plate 13 are rotatably connected to the two ends of the main board 11 through the two hinge assemblies 20, and the pitch plate 12 is used to carry camera products, etc. Figure 1 , Figures 3 to 5As shown, specifically, one end of the main board 11 is recessed downward to form a first slot 111, and the bottom of the other end is recessed upward to form a second slot 112, and one end of the pitch plate 12 and the support plate 13 are respectively formed with a first convex shaft 121 and a second convex shaft 131 outwardly, and the first convex shaft 121 and the second convex shaft 131 are respectively located in the first slot 111 and the second slot 112, a rotating member 22 of the hinge assembly 20 is located in the first convex shaft 121, and the two ends of the connecting member 21 sleeved with the rotating member 22 are fixed to the main board 11, and the rotating member 22 of the other hinge assembly 20 is located in the second convex shaft 131, and the two ends of the connecting member 21 sleeved with the rotating member 22 are fixed to the main board 11, so as to realize the rotational connection between the pitch plate 12 and the main board 11 and the support plate 13 and the main board 11. When the hinge assembly 20 of the utility model is used in the bracket 100, the rotating member 22 can rotate around the connecting member 21, so that the pitch plate 12 and the support plate 13 can respectively rotate relative to the main board 11 with the two hinge assemblies 20 as the axis, without the need for nuts or locking screws, so the cost is low and the bracket 100 can be made thinner as a whole. At the same time, the damping force is not affected by the number of rotations, which can increase the service life.

[0024] In certain embodiments, such as Figure 1 , Figure 5 and Figure 7 As shown, the rotating member 22 is a hollow cylinder, and a groove 223 extending from the front end to the rear end of the rotating member 22 is provided on the side wall of the rotating member 22, and the top wall of the groove 223 protrudes outward to form a protruding position 222; accordingly, a first rotating groove 122 and a second rotating groove 132 are respectively provided in the first convex shaft 121 and the second convex shaft 131, and the first rotating groove 122 and the second rotating groove 132 are also connected to the inside of the first convex shaft 121 and the inside of the second convex shaft 131 respectively. When the rotating member 22 is located at the first convex shaft 121 / the second convex shaft 131, the protruding position 222 is located in the first rotating groove 122 / the second rotating groove 132, and when the protruding position 222 is located in the first rotating groove 122 / the second rotating groove 132, it can also move in the first rotating groove 122 / the second rotating groove 132, so as to further loosen and fine-tune when the rotating member 22 rotates.

[0025] Furthermore, the bottom of the inner wall of the rotating member 22 is recessed downward to form a placement groove 221 for storing lubricating grease, and the outer surface of one end of the connecting member 21 located inside the rotating member 22 is provided with at least one groove 2113 for storing lubricating grease, so that lubricating oil can be added during use, thereby facilitating rotation.

[0026] Preferably, continue to refer to Figure 1 , Figure 3 and Figure 6 In this embodiment, the connecting member 21 includes two connecting shafts 211, which are respectively arranged on both sides of the rotating member 22, and one end of the two connecting shafts 211 passes through both sides of the rotating member 22 and is located in the rotating member 22, so that the rotating member 22 can rotate relative to the connecting shafts 211. Based on the above design, when the pitch plate 12 is assembled with the main board 11, the two connecting shafts 211 are respectively located on both sides of one end of the main board 11, pass through the main board 11 and the rotating member 22 in sequence, and are located in the rotating member 22, and when the support plate 13 is assembled with the main board 11, the two connecting shafts 211 of the connecting member 21 in the other hinge assembly 20 are respectively located on both sides of the other end of the main board 11, pass through the main board 11 and the rotating member 22 in sequence to realize the hinge connection between the support plate 13 and the main board 11. It is understandable that in some other embodiments, the connecting member 21 may also include a connecting shaft 211, and the rotating member 22 is sleeved on the middle part of the connecting shaft 211. Both ends of the connecting shaft 211 are fixed on the main board 11, which can also realize the rotational connection between the support plate 13 and the pitch plate 12 and the main board 11.

[0027] In some embodiments, the connecting shaft 211 includes a first shaft 2111 and a second shaft 2112 extending outward from one end of the first shaft 2111. The side walls at both ends of the main board 11 are provided with through holes 113. The second shaft 2112 passes through the through hole 113 at the end of the main board 11 and then passes through the rotating member 22. The groove 2113 is provided on the second shaft 2112, and the arc radius of the second shaft 2112 is smaller than the arc radius of the first shaft 2111. Preferably, in this embodiment, the cross section of the first shaft 2111 is a convex polygon, such as Figure 1 and Figure 6 As shown, the two side surfaces of the first shaft body 2111 are non-arc surfaces, which can prevent the connecting shaft 211 from rotating and further fix the connection between the connecting shaft 211 and the main board 11.

[0028] Furthermore, for the overall aesthetics of the bracket 100, after the hinge assembly 20 is assembled to the main board 11 and the pitch plate 12 as well as the main board 11 and the support plate 13, the through holes 113 on the side walls at both ends of the main board 11 for the connecting shaft 211 to pass through are equipped with silicone plugs 14 to cover the connecting shaft 211.

[0029] When the bracket 100 of the utility model is used, the pitch plate 12 can rotate relative to the main board 11 with the connecting piece 21 of the hinge assembly 20 as the axis, and the support plate 13 can rotate relative to the main board 11 with the connecting piece 21 of another hinge assembly 20 as the axis, so as to form a two-axis three-plate structure. When the camera product is placed on the pitch plate 12, the user can rotate the pitch plate 12 / main board 11 to make the rotating piece 22 rotate around the connecting axis 211 to adjust the angle of the pitch plate 12, thereby adjusting the pitch shooting angle of the camera product. The relative angle between the support plate 13 and the main board 11 can also be adjusted by the hinge assembly 20 (such as Figure 4 As shown), the center of gravity of the camera product can be fine-tuned forward and backward, so that the center of gravity of the camera product can be relatively backward to prevent tipping, and the product installation is more stable. It can be understood that the camera product can be fixed on the pitch plate 12 of the bracket 100 of the utility model by magnetic attraction or adhesive, and the end surface of the pitch plate 12 in contact with the camera product can be made of silicone material to increase the contact friction between the camera product and the pitch plate 12, and the camera product can also be non-slip when placed.

[0030] To sum up, when the hinge assembly of the utility model is in use, the rotating part can rotate around the connecting part. When applied to the bracket, the pitch plate and the support plate can respectively rotate relative to the main board with the two hinge assemblies as the axis, and the angle can be adjusted without the need for nuts or locking screws. The structure is simple and the cost is low. The bracket as a whole can be made lighter and thinner, which is convenient for carrying and storage. At the same time, the damping force is not affected by the number of rotations. Even a high number of rotations will not affect the service life of the hinge assembly, thereby increasing the service life.

[0031] The above-mentioned preferred implementation modes should be regarded as examples of the implementation modes of the utility model scheme. Any technical deductions, replacements, improvements, etc. that are identical or similar to the utility model scheme or made based on it should be regarded as within the scope of protection of this patent.
