Specific embodiments

[0025] Next, in combination with the accompanying drawings and specific embodiments, the present utility model will be further described. It should be noted that, on the premise of no conflict, any combination of the following described embodiments or technical features can form a new embodiment.

[0026] It should be noted that all directional indications (such as up, down, left, right, front, back, inside, outside, top, bottom...) in the embodiments of the present utility model are only used to explain the relative positional relationship between components in a specific posture (as shown in the attached drawings), etc. If this specific posture changes, then the directional indications will change accordingly.

[0027] It should also be noted that when an element is referred to as being "fixed to" or "disposed on" another element, the element can be directly on the other element or there may be an intermediate element present at the same time. When an element is referred to as "connected to" another element, it can be directly connected to the other element or there may be an intermediate element present at the same time.

[0028] Please refer to Figures 1 to 7 , a support assembly 10 provided by an embodiment of the present utility model includes a support device 12 and a base 14. The base 14 is used for mounting a camera, and the support device 12 is used to support the base 14 and is fixed to an external device. In this application, the external device is taken as an example of an automobile for illustration. The support device 12 is used to be fixed to the mounting position of the automobile, such as positions like the windshield, rearview mirror, license plate frame, etc., so as to indirectly mount the base 14, that is, the camera, on the vehicle. The support device 12 is detachably connected to the base 14, so that when the camera fails, the assembly of the base 14 and the camera can be detached from the support device 12 for repair or replacement.

[0029] The specific functions of the assembly of the base 14 and the camera are not limited, and it can be a driving recorder or a digital product for assisting in parking, driving, etc.

[0030] The specific manner in which the support device 12 is fixed to the mounting position is not limited, such as by adhesive, suction cup, bolt, etc. In this application, a glue layer 15 is provided on the bottom of the support device 12, that is, the side away from the base 14, and the support device 12 is adhesively fixed to the mounting position through this glue layer 15.

[0031] The support device 12 includes a mounting seat 16 and a connecting member 18. The mounting seat 16 is used to be fixed to the mounting position, and the connecting member 18 is rotatably mounted to the mounting seat 16 so that the connecting member 18 can rotate relative to the mounting seat 16. The base 14 is connected to the connecting member 18, so that when the connecting member 18 rotates relative to the mounting seat 16, it drives the base 14 and the camera on the base 14 to rotate together, thereby adjusting the position of the camera.

[0032] The base 14 includes a housing 20, and the camera 22 is installed on the housing 20. The connecting member 18 is detachably connected to the housing 20, thereby realizing the detachable connection between the base 14 and the support device 12.

[0033] The specific number of the cameras 22 is not limited, and it can be one or multiple. In this embodiment, the number of the cameras 22 is two, and the two cameras 22 are respectively installed on opposite sides of the housing 20, which can not only expand the shooting angle, but also prevent partial overlap of the shooting angles of the two cameras.

[0034] The connecting member 18 includes a plugging portion 24. The housing 20 is provided with a mounting hole 25 and a plugging hole 26, and the mounting hole 25 and the plugging hole 26 are respectively located at two ends of the housing 20. The camera 22 is installed into the mounting hole 25, and the plugging portion 24 is inserted into the plugging hole 26 to form a plugging fit, so that the supporting device 12 and the base 14 are detachably connected. When the plugging portion 24 is inserted into the plugging hole 26, the supporting device 12 and the base 14 can be connected together. When the plugging portion 24 is pulled out from the plugging hole 26, the supporting device 12 and the base 14 can be separated. The connection and separation between the supporting device 12 and the base are realized by plugging and unplugging, so that the supporting device 12 and the base 15 can be installed or disassembled in a single direction, and the operation is simple and convenient for one-handed operation.

[0035] In this embodiment, the plugging portion 24 is provided with a magnetic attracting member 28, and the base 14 is provided with a metal member 30 that attracts the magnetic attracting member 28. Specifically, the plugging portion 24 and the inner wall of the plugging hole 26 of the housing 20 are respectively recessed with a receiving portion, and the magnetic attracting member 28 and the metal member 30 are respectively received in the corresponding housing and are flush with the outer surface of the plugging portion 24 and the inner wall of the plugging hole 26 respectively. When the plugging portion 24 is inserted into the plugging hole 26, the magnetic attracting member 28 and the metal member 30 attract each other to generate a magnetic attraction force to enhance the connection strength between the supporting device 12 and the base 14 and reduce the risk of the supporting device 12 and the base 14 being separated. Moreover, the cooperation between the magnetic attracting member 28 and the metal member 30 can not only form a magnetic attraction effect to enhance the stability of the base 14, but also prevent the problem that the base 14 is difficult to disassemble due to excessive magnetic attraction force.

[0036] In other embodiments, a magnetic attracting member 28 is provided on the housing 20, and a metal member 30 is correspondingly provided on the plugging portion 24, or the metal member 30 on the housing 20 or the plugging portion 24 is replaced with another magnetic attracting member, and the effect of magnetic attraction cooperation can also be formed.

[0037] In one embodiment, the plugging portion 24 is inclined relative to the mounting seat 16, and the plugging hole 26 and the camera 22 are respectively located at two ends of the housing 20. After the plugging portion 24 is inserted into the plugging hole 26, the base 14 is in an inclined state relative to the mounting seat 16, which can not only reduce the overall height of the supporting assembly 10, but also avoid the plugging portion 24 blocking the base 14.

[0038] The mounting base 16 includes a mounting surface 31 for mounting to an external device. The insertion direction between the insertion portion 24 and the insertion hole 26 forms an angle α with the mounting surface 31 of the mounting base 16, where α is greater than 0° and less than 90°. In this embodiment, the mounting surface 31 is the surface of the mounting base 16 where the adhesive layer 15 is provided. The mounting surface 31 is a plane, and the angle formed between the insertion direction and the mounting surface 31 is an acute angle. Preferably, α is greater than 30° and less than 60°, for example, 45°, to prevent the angle from being too small or too large.

[0039] The axis of the mounting hole 25 forms an angle with the mounting surface 31 of the mounting base 16, that is, the axis of the mounting hole 25 is not parallel to the mounting surface 31. Specifically, the axis of the mounting hole 25 on the housing 20 is the same as the insertion direction of the insertion portion 24 and the insertion hole 26, and the angle between the axis of the mounting hole 25 and the mounting surface 31 is also α.

[0040] In one embodiment, the housing 20 is substantially square, including four side walls 202 and two end walls 204. The four side walls 202 are arranged in pairs opposite to each other, and the two end walls 204 are respectively connected to the two ends of the four side walls 202. The insertion holes 26 are provided at the junctions of three of the side walls 202 and one of the end walls 204 to reduce the area of the circumferential inner wall of the insertion holes 26, thereby reducing the contact area between the insertion portion 24 and the housing 20, reducing the insertion and extraction force between the insertion portion 24 and the housing 20, and facilitating disassembly and assembly.

[0041] Specifically, the insertion hole 26 has a square opening, and the four sides of the square opening are respectively located on three of the side walls 202 and one end wall 204.

[0042] The insertion hole 26 includes a pair of opposite side surfaces 262 and a pair of opposite end surfaces 264. The two side surfaces 262 are respectively connected between the two end surfaces 264. The area of one end surface 264 close to the mounting hole 25 is larger than the area of the other end surface 264 far from the mounting hole 25, and the transition between the side surface 262 and the end surface 264 is arc-shaped. The insertion hole 26 has an opening, and the opening includes an opposite top edge and bottom edge, and a pair of opposite side edges. The top edge and the bottom edge are respectively located at the top of the end surface 264, and the two side edges are respectively located at the top of the two side surfaces 262. The two side edges respectively extend obliquely from the two ends of the top edge to the bottom edge, and the top edge is closer to the mounting hole 25 for mounting the camera than the bottom edge. Making the area of the end surface 264 close to the mounting hole 25 larger than the area of the end surface 264 far from the mounting hole 25 can reduce the area of the two side surfaces 262 and one end surface 264 of the insertion hole 26 compared with the way of arranging the insertion hole 26 on one of the side walls 202, thereby reducing the contact area with the insertion portion 24, helping to reduce the insertion and extraction force between the inner wall surface of the insertion hole 26 and the insertion portion 24, and facilitating the extraction of the insertion portion 24 from the insertion hole 26.

[0043] Understandably, the two side surfaces 262 and the two end surfaces 264 can be parallel to each other or not. Preferably, the two side surfaces 262 are parallel to each other, and the two end surfaces 264 are parallel to each other.

[0044] In one embodiment, a recessed portion 32 is provided on the plugging portion 24, and a first connection terminal 34 is provided in the recessed portion 32. A protruding portion 36 corresponding to the recessed portion 32 is provided in the plugging hole 26, and a second connection terminal 38 is provided on the protruding portion 36. The second connection terminal 38 is used for plugging and mating with the first connection terminal 34 to form an electrical connection effect. After the plugging portion 24 is inserted into the plugging hole 26, the protruding portion 36 will also be inserted into the recessed portion 32. The cooperation between the protruding portion 36 and the recessed portion 32 can play a certain limiting effect. Moreover, after the protruding portion 36 is inserted into the recessed portion 32, the first connection terminal 34 will automatically be plugged together with the second connection terminal 38. That is, after the plugging portion 24 is inserted into the plugging hole 26, not only can the supporting device 12 and the base 14 be plugged and mated, but also an electrical connection effect between the supporting device 12 and the base 14 can be formed. There is no need to additionally provide a wire to connect the supporting device 12 and the base 14, and the overall structure is more compact and concise. After the supporting device 12 is connected to the power source or the central control panel of the vehicle, electrical energy can be provided to the electrical appliances on the base 14, such as the camera 22.

[0045] Specifically, the protruding portion 36 is provided on the end surface 264 of the plugging hole 26 close to the mounting hole 25. The area of the end surface 264 close to the mounting hole 25 is relatively large, which can provide a larger mounting space and facilitate the setting of the protruding portion 36.

[0046] A guiding structure 40 is provided between the outer wall of the plugging portion 24 and the inner wall of the plugging hole 26. The guiding structure 40 can play a guiding effect during the process of inserting the plugging portion 24 into the plugging hole 26 to assist in assembly.

[0047] The guiding structure 40 includes a guiding groove 42 and a guiding block 44. The guiding block 44 is provided in the plugging hole 26, and the guiding groove 42 is provided on the outside of the plugging portion 24. The guiding groove 42 and the guiding groove 42 respectively extend along the extending direction of the plugging portion 24, that is, the direction in which the plugging portion 24 is inserted into the plugging hole 26. When the plugging portion 24 is inserted into the plugging hole 26, the guiding block 44 is inserted into the guiding hole, so that the plugging portion 24 can only move along the extending direction of the guiding block 44, thereby playing a guiding effect.

[0048] Preferably, the number of the guiding blocks 44 and the guiding grooves 42 is two and they correspond to each other one by one. The two guiding blocks 44 are respectively provided on two opposite inner walls of the plugging hole 26, and the two guiding grooves 42 are respectively provided on two opposite sides of the plugging portion 24.

[0049] In one embodiment, the connecting member 18 further includes a universal ball 46, which is connected to one end of the plugging portion 24 away from the base 14. A universal hole 48 is provided on the mounting base 16, and the shape of the universal hole 48 matches the shape of the universal ball. The universal ball 46 is movably received in the universal hole 48, so that the connecting member 18 and the mounting base 16 form a universal fit, enabling the connecting member 18 to rotate relative to the mounting base 16 both in the horizontal plane and in the vertical plane. The universal ball 46 can rotate within the universal hole 48 and drive the plugging portion 24 and the base 14 to move together during the rotation process, thereby increasing the shooting angle of the base 14. Moreover, since the connecting member 18 and the mounting base 16 form a universal fit, the rotation angle of the connecting member 18 relative to the mounting base 16 can be larger, thus increasing the rotation angle of the base 14.

[0050] A soft rubber sleeve 50 is provided in the universal hole 48. The soft rubber sleeve 50 is relatively fixed to the mounting base 16 and wraps around the outside of the universal ball 46. Specifically, the universal ball 46 and the mounting base 16 are made of hard rubber. By providing the soft rubber sleeve 50 between the universal ball 46 and the mounting base 16, hard contact between the universal ball 46 and the mounting base 16 can be prevented, resulting in a better rotation feel, stronger wear resistance, little change in the rotation force during long-term use, and good structural stability.

[0051] A first limiting member 52 is provided inside the connecting member 18, and a second limiting member 54 is provided inside the mounting base 16. The first limiting member 52 is relatively fixed to the connecting member 18, and the second limiting member 54 is relatively fixed to the mounting base 16. The universal ball 46 is hollow, and the first limiting member 52 and the second limiting member 54 are respectively received inside the universal ball 46 and are arranged opposite to each other at intervals. Specifically, the whole of the first limiting member 52 is received inside the universal ball 46, and part of the second limiting member 54 is received inside the universal ball 46 and part is located outside the universal ball 46 and is fixedly connected to the mounting base 16. When the connecting member 18 moves relative to the mounting base 16, it will drive the first limiting member 52 to move relative to the second limiting member 54. After the first limiting member 52 abuts against the second limiting member 54, the second limiting member 54 can prevent the first limiting member 52 from continuing to move in this direction, that is, prevent the connecting member 18 from moving relative to the mounting base 16 in this direction, thereby achieving a limiting effect.

[0052] Specifically, both the first limiting member 52 and the second limiting member 54 are metal parts 30, and the metal parts 30 have higher strength to enhance the overall strength of the connecting member 18 and the mounting base 16.

[0053] The specific ways of fixing the first limiting member 52 and the second limiting member 54 to the connecting member 18 and the mounting base 16 are not limited, such as glue fixing, mechanical fixing, etc. In this embodiment, the first limiting member 52 is relatively fixed to the connecting member 18 through an uneven structure, and the second limiting member 54 is relatively fixed to the mounting base 16 through fasteners such as screws, which is convenient for disassembly and assembly.

[0054] Specifically, the first position-limiting member 52 includes a first body 55 and a first position-limiting portion 56, the first position-limiting portion 56 extends from the first body 55 toward the second position-limiting member 54 and is spaced apart from the second body 57 of the second position-limiting member 54. The second position-limiting member 54 includes a second body 57 and a second position-limiting portion 58, the second position-limiting portion 58 extends from the second body 57 toward the first position-limiting member 52 and is spaced apart from the first body 55 of the first position-limiting member 52. During the rotation of the connecting member 18 relative to the mounting seat 16, when the first position-limiting portion 56 abuts against the second body 57 of the second position-limiting member 54, for example, the position can be limited in the front-to-back direction, or when the second position-limiting portion 58 abuts against the first body 55 of the first position-limiting member 52, for example, the position can be limited in the left-to-right direction, and the second position-limiting member 54 can form a limiting effect on the base 14.

[0055] The specific shapes of the first limiting portion 56 and the second limiting portion 58 are not limited, such as a convex column, a convex block, etc.

[0056] The first limiting portion 56 and the second limiting portion 58 are respectively located in two mutually perpendicular radial directions of the universal sphere 46 , so that the first limiting portion 56 and the second limiting portion 58 can form limiting effects in different directions.

[0057] The specific number of the first limiting portion 56 and the second limiting portion 58 is not limited, for example, one, two, three or more. In this embodiment, the number of the first limiting portion 56 and the second limiting portion 58 is two, the two first limiting portions 56 are spaced opposite to each other, the two second limiting portions 58 are spaced opposite to each other, and the connecting line of the two first limiting portions 56 and the connecting line of the two second limiting portions 58 are perpendicular to each other, so that the connecting line of the two is in a cross shape.

[0058] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
