[0031] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0032] The various specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction, for example, different embodiments and technical solutions can be formed by combining different specific technical features. In order to avoid unnecessary repetition, the various possible combinations of the specific technical features in the utility model will not be described separately.

[0033] In the following description, the terms "first\second\..." are only used to distinguish different objects, and do not mean that the objects have the same or related points. It should be understood that the directions "above", "below", "outside" and "inside" are all directions in normal use, and the directions "left" and "right" refer to the left and right directions shown in the corresponding schematic diagrams, which may or may not be the left and right directions in normal use.

[0034] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprising a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element. The term "connected" includes both direct and indirect connections unless otherwise specified.

[0035] In the following specific embodiments, the bracket device can be connected to any type of electronic device and can adjust the position and posture of the electronic device. For example, the bracket device can be applied to a mobile phone, the bracket device can be applied to a computer, the bracket device can be applied to a gimbal, and the bracket device can also be applied to a camera device.

[0036] In some embodiments, Figure 1 As shown, the bracket device 10 includes a base 100 and a connector 200. The base 100 can be fixed to an external fixed structure to fix the bracket device 10, and the fixation can be achieved by placing the base 100 on a horizontal plane, or by fixing the base 100 to the fixed structure.

[0037] Among them, the base 100 has a first connecting structure 110, the connecting member 200 is used to connect with the electronic device 20, and has a second connecting structure 210, one of the first connecting structure 110 and the second connecting structure 210 is a ball head, and the other of the first connecting structure 110 and the second connecting structure 210 is a ball socket. By accommodating the ball head in the ball socket and forming an interference fit between the ball head and the ball socket, a universal ball kinematic pair can be formed, so that the electronic device 20 can rotate relative to the base 100, that is, the electronic device 20 can rotate in any direction around the center of the ball head, so as to adjust the position and posture of the electronic device 20.

[0038] At the same time, the bracket device 10 also includes an abutment structure 300, which protrudes from the surface of the ball head and / or the surface of the ball socket. It can be understood that during the use of the bracket device 10, due to the interference fit formed between the ball head and the ball socket, the ball head or the ball socket may be worn during the relative rotational movement of the ball head and the ball socket. Such wear may cause the interference fit of the ball head and the ball socket to be transformed into a transition fit in some areas, or even transformed into a clearance fit, thereby causing an offset between the center of the ball head and the center of the ball socket during the rotation of the ball head relative to the ball socket, thereby causing the electronic device 20 to generate additional translational motion in addition to the required rotation, and the additional translational motion causes an adjustment error of the electronic device 20.

[0039] It is on the basis of being aware of the above-mentioned technical problems that the applicant has come up with the idea of ​​providing an abutment structure 300 on the surface of the ball head and / or the ball seat, thereby improving the reliability of the interference fit between the ball head and the ball seat. For the sake of convenience of explanation, the following takes the abutment structure 300 provided on the ball head as an example to explain the principle of improving the reliability of the interference fit between the ball head and the ball seat by providing the abutment structure 300.

[0040] By making the abutment structure protrude from the surface of the ball head, a greater degree of interference fit can be achieved between the ball head and the ball socket. Even if wear occurs during use, the abutment structure 300 will first replace the surface of the ball head and the ball socket to wear, and there is still an interference fit between the ball head and the ball socket. Even if part of the abutment structure 300 is worn, the fit formed between the various parts of the surface of the ball head and the various parts of the surface of the ball socket is still an interference fit, that is, the interference fit between the ball head and the ball socket may fail only after all the abutment structures 300 are worn, thereby improving the reliability of the interference fit between the ball head and the ball socket. Moreover, since the abutment structure 300 protrudes from the surface of the ball head, the wear of the abutment structure 300 is easier to observe compared to the wear of the surface of the ball head, so that it is easier for operators or maintenance personnel to know whether the ball head with the abutment structure 300 needs to be replaced, thereby improving the maintenance convenience of the bracket device 10. At the same time, since the abutment structure 300 protrudes from the ball head, the material of the abutment structure 300 can be set to a more wear-resistant material instead of setting the entire ball head to a more wear-resistant material, thereby further improving the reliability of the interference fit between the ball head and the ball seat at a lower cost.

[0041] The embodiment of the present application provides a bracket device, which includes a base with a first connection structure and a connector with a second connection structure for connecting to an electronic device, and the connector can be connected to the first connection structure through the second connection structure; wherein one of the first connection structure and the second connection structure is a ball head, and the other of the first connection structure and the second connection structure is a ball seat, and the connector and the base can be rotatably connected by making the ball seat accommodate the ball head and forming an interference fit between the ball head and the ball seat. At the same time, the bracket device also includes an abutment structure, which protrudes from the surface of the ball head and / or the ball seat, so that the ball head and the ball seat can have a greater degree of interference fit, even if wear occurs during use, the abutment structure first replaces the surface of the ball head and the ball seat to wear, and the ball head and the ball seat are also interference fit, even if part of the abutment structure is worn, the fit formed between each part of the surface of the ball head and each part of the surface of the ball seat is still interference fit, that is, the interference fit between the ball head and the ball seat may fail only after all the abutment structures are completely worn, thereby improving the reliability of the interference fit between the ball head and the ball seat. Moreover, since the abutment structure protrudes from the surface of the ball head and / or the ball seat, the wear of the abutment structure is easier to observe than the wear of the surface of the ball head and / or the ball seat, thereby enabling operators or maintenance personnel to more easily know whether the ball head and / or the ball seat with the abutment structure needs to be replaced, thereby improving the maintenance convenience of the bracket equipment.

[0042] In some embodiments, Figure 2As shown, the connector 200 includes: a connecting rod 230 and a second connecting structure 210. The connecting rod 230 has a mounting end 232 and a connecting end 231 opposite to each other. The mounting end 232 is used to mount the electronic device 20. The connecting end 231 has a second connecting structure 210, and the second connecting structure 210 is a ball head. It can be understood that the connecting end 231 of the connecting rod 230 extends in a direction away from the electronic device 20, so that there is a certain distance between the ball head and the electronic device 20, so that the ball head (second connecting structure 210) and the ball seat ( Figure 1 In the process of relative movement between the first connecting structure 110 in the embodiment of the present invention, the possibility of collision between the electronic device 20 and the base 100 is reduced, that is, the possibility of motion interference between the electronic device 20 and the base 100 is reduced.

[0043] At the same time, the abutment structure 300 is arranged on the ball head (the second connecting structure 210), which can reduce the manufacturing difficulty of the abutment structure 300. Specifically, during the processing, the surface of the ball head is exposed to the outside, and the surface of the ball seat is the cavity wall of the spherical cavity in the base. Compared with setting a protruding structure on the cavity wall, setting a protruding structure on the surface of the ball head exposed to the outside has lower processing difficulty.

[0044] In some embodiments, Figure 3 As shown, there are multiple abutment structures 300, and each abutment structure 300 is arranged at intervals on the surface of the ball head (second connection structure 210), so that the multiple abutment structures 300 can bear wear together, further improving the reliability of the interference fit between the ball head and the ball seat. It should be noted that the distribution form of the multiple abutment structures 300 on the surface of the ball head can be in any form. Figures 3 to 5 The distribution of the abutment structure 300 on the surface of the ball head is exemplified. Those skilled in the art should understand that the distribution of the abutment structure 300 on the surface of the ball head can also be other than Figures 3 to 5 Other distributions than those shown in .

[0045] like Figure 3 As shown, each abutment structure is arranged along the extension direction of the connecting rod 230 (the extension direction of the connecting rod 230 is as shown in FIG. Figure 3 As shown by arrow I in the middle) interval setting; Figure 4 As shown, a plurality of abutment structures 300 are arranged at intervals around the central axis L1 of the connecting rod 230; Figure 5 As shown, a plurality of abutment structures 300 are arranged at intervals around the central axis L1 of the connecting rod 230 to form a group of abutment clusters 310. The plurality of abutment clusters 310 are arranged along the extension direction of the connecting rod 230 (the extension direction of the connecting rod 230 is shown in FIG. Figure 5The abutment structures 300 are arranged at intervals along the extension direction of the connecting rod 230 and are arranged at intervals around the central axis L1 of the connecting rod 230, so that the distribution of the abutment structures 300 on the surface of the ball head (the second connecting structure 210) is more uniform, so that the degree of wear of each abutment structure 300 during use is roughly consistent, thereby further improving the service life of the ball head with the abutment structure 300; optionally, the abutment structures 300 in adjacent abutment clusters 310 are not aligned. Specifically, the abutment structure 300 of one of two adjacent abutment clusters 310 is located between the two abutment structures 300 in the other abutment cluster 310, thereby further improving the uniformity of the arrangement of the abutment structures 300 on the surface of the ball head, and further improving the service life of the ball head with the abutment structure 300.

[0046] In some embodiments, in combination Figure 6 and Figure 7 The end of the abutment structure 300 away from the mounting end 232 has a first guide structure 321. From the direction away from the mounting end 232 to the direction close to the mounting end 232, the size of the first guide structure 321 protruding from the ball head (the second connecting structure 210) increases gradually, thereby forming an inclined surface or an arc surface with a gradually protruding surface of the ball head. In the process of installing the ball head into the ball socket, the end of the abutment structure 300 away from the mounting end 232 faces the ball socket, and the first guide structure 321 of the abutment structure 300 can abut against the inner wall of the ball socket, so that the inner wall of the ball socket produces an outward elastic deformation, thereby reducing the difficulty of installing the ball head into the ball socket. That is, by arranging the first guide structure 321 at the end of the abutment structure 300 facing the ball socket, a greater interference fit can be formed between the ball head and the ball socket, while reducing the difficulty of assembling the ball head and the ball socket with the abutment structure 300.

[0047] In some embodiments, Figure 8 As shown, the abutment structure 300 is symmetrically arranged with respect to the first symmetry plane S1 of the ball head (the second connection structure 210), the first symmetry plane S1 is a plane passing through the center of the ball head, and the first symmetry plane S1 is parallel to the extension direction of the connecting rod 230 (the extension direction of the connecting rod 230 is shown in FIG. Figure 8 By arranging the abutment structure 300 symmetrically with respect to the first symmetry plane S1, the wear degree of each part of the abutment structure 300 can be made more uniform, thereby improving the service life of the ball head with the abutment structure 300. The following describes the principle that arranging the abutment structure 300 symmetrically with respect to the first symmetry plane S1 can make the wear degree of the abutment structure 300 more uniform, in combination with the movement of the ball head and the ball seat.

[0048] When the ball head rotates around the central axis L1 of the connecting rod 230, the abutment forces between the abutment structures 300 and the cavity wall of the ball seat are the same, and the wear conditions of the abutment structures 300 are the same. Figure 2 When the electronic device 20 in the connecting rod 230 rotates about a rotation axis perpendicular to the central axis L1 of the connecting rod 230, it is necessary to apply a force around the rotation axis to the electronic device 20. In addition to driving the ball center sleeve to rotate about the rotation axis relative to the ball seat, the force will also generate an additional force perpendicular to the first symmetry plane S1. The force will cause a difference in the degree of wear of the abutment structure 300 on both sides of the first symmetry plane S1. For example, for the sake of convenience, the side perpendicular to the first symmetry plane S1 is referred to as the upper side, and the other side of the first symmetry plane S1 is referred to as the lower side (the upper side and the lower side are in the same direction). Figure 8 In the figure, the additional force is indicated by an arrow. When the additional force is directed downward, the abutment structure 300 below the first symmetry plane S1 needs to withstand a greater degree of wear than the abutment structure 300 above the first symmetry plane S1. When the additional force is directed upward, the abutment structure 300 above the first symmetry plane S1 needs to withstand a greater degree of wear than the abutment structure 300 below the first symmetry plane S1. At the same time, since the angle of the electronic device 20 needs to be adjusted back to the initial position after use, that is, the rotational movement of the electronic device 20 around the rotation axis is generally symmetrical, so that the action of the electronic device 20 around the rotation axis is The forces are generally two forces of equal magnitude and opposite directions, and the additional forces generated by the two forces are also equal in magnitude and opposite in directions, so that the differences in the degree of wear that the abutment structures 300 on both sides of the first symmetry plane S1 need to withstand during the two rotational movements can offset each other, that is, the degree of wear that the abutment structures 300 located on both sides of the first symmetry plane S1 need to withstand is the same, and by making the abutment structures 300 symmetrically distributed relative to the first symmetry plane S1, the same abutment structures 300 are subjected to the same degree of wear, and then the wear degree area of ​​the abutment structures 300 is consistent, thereby further improving the service life of the ball head with the abutment structure 300.

[0049] In some embodiments, since the abutting structure 300 is symmetrically arranged relative to the first symmetry plane S1, when the abutting structure 300 is away from Figure 2 On the basis of having a guide structure at the end of the mounting end 232, a symmetrical guide structure may also be provided on the other side of the abutment structure 300. The symmetrically arranged guide structure can cause the ball seat to produce outward elastic deformation during the process of separating the ball head from the ball seat, thereby facilitating the separation of the ball head from the ball seat. The specific structure of the symmetrically arranged guide structure is exemplified below in combination with different distribution forms of the abutment structure 300.

[0050] Combination Fig. 9 and Fig.10 The ball head (second connection structure 210) includes an insertion side 211 and a removal side 212, and the insertion side 211 is located away from the first symmetry plane S1. Figure 2 The removal side 212 is located near the first symmetry plane S1. Figure 2 At one side of the mounting end 232, the mounting side 211 first contacts the ball seat during the process of mounting the ball head into the ball seat, and the removal side 212 first contacts the ball seat during the process of removing the ball head from the ball seat. At the same time, the abutment structure 300 extends from the mounting side 211 to the removal side 212, that is, a plurality of abutment structures 300 are arranged at intervals around the central axis L1 of the connecting rod 230, and the abutment structures 300 span the first symmetry plane S1 and form opposite first and second ends 331 and 332, the first end 331 is located at the mounting side 211, and the second end 332 is located at the removal side 212, wherein the first end 331 has a second guide portion 322, and the size of the second guide portion 322 protruding from the surface of the ball head in the direction from the first end 331 to the second end 332 is gradually increased. The second end 332 has a third guide portion 323, and the size of the surface of the third guide portion 323 protruding from the ball head increases in the direction from the second end 332 to the first end 331, so that in the process of removing the ball head from the ball socket, the third guide portion 323 can abut against the ball socket and cause the ball socket to produce an outward elastic deformation, thereby making it easier for the ball head to be removed from the ball socket.

[0051] Combination Fig.11 and Fig.12 The ball head (second connection structure 210) includes an insertion side 211 and a removal side 212, and the insertion side 211 is located away from the first symmetry plane S1. Figure 2 The removal side 212 is located near the first symmetry plane S1. Figure 2 The mounting end 232 of the connecting rod 230 is disposed on one side of the connecting rod 230. When the ball head is mounted on the ball seat, the mounting side 211 first contacts the ball seat. When the ball head is removed from the ball seat, the removal side 212 first contacts the ball seat. Fig.11As shown by the arrow I in the middle, a portion of the abutment structure 300 is arranged at intervals, so that a portion of the abutment structure 300 is located at the loading side 211, and a portion of the abutment structure 300 is located at the removal side 212. For the convenience of explanation, the abutment structure 300 located at the loading side 211 is referred to as the loading abutment structure 341, and the abutment structure 300 located at the removal side 212 is referred to as the removal abutment structure 342. The end of the loading abutment structure 341 away from the mounting end 232 forms a third end 333, and the third end 333 has a fourth guide structure 324. In the direction from the third end 333 to the mounting end 232, the size of the surface of the fourth guide structure 324 protruding from the ball head The fourth guide structure 324 is gradually increased, so that in the process of installing the ball head into the ball socket, the fourth guide structure 324 can abut against the ball socket and cause the ball socket to produce an outward elastic deformation, so that the ball head is easier to install into the ball socket; the end of the abutment structure 342 close to the mounting end 232 is removed to form a fourth end 334, and the fourth end 334 has a fifth guide structure 325. In the direction from the fourth end 334 to the third end 333, the size of the surface of the fifth guide structure 325 protruding from the ball head increases, so that in the process of removing the ball head from the ball socket, the fifth guide structure 325 can abut against the ball socket and cause the ball socket to produce an outward elastic deformation, so that the ball head is easier to remove from the ball socket.

[0052] In some embodiments, Fig.13 As shown, the ball head also includes a central portion 213, which is located between two first planes S2. The two first planes S2 are parallel to the first symmetry plane S1 and are symmetrically distributed relative to the first symmetry plane S1. The ratio of the distance D1 between the two first planes S2 and the diameter D2 of the ball head is between 0.15 and 0.16. At the same time, the abutment structure 300 located in the central portion 213 forms a central abutment structure 343, and the central abutment structure 343 extends around the central axis L1 of the connecting rod 230 to form an annular protrusion, that is, the central abutment structure 343 forms an annular structure connected end to end. Compared with the abutment structure arranged at intervals along the central axis L1 of the sleeve, the central abutment structure 343 has a stronger ability to withstand wear.

[0053] It can be understood that, in the area close to the center of the ball head defined by two first planes S2 parallel to the first symmetry plane S1, in the direction parallel to the first symmetry plane S1, the distance between the point on the surface of the ball head in this area and the center of the ball is greater than the distance between the point on the surface of the ball head in the remaining areas and the center of the ball. The degree of wear that the abutment structure in this area needs to withstand is higher than the degree of wear that the abutment structure in the remaining areas needs to withstand. At the same time, by setting the central abutment structure 343 located in the central area as an annular protrusion structure with stronger wear resistance, the wear resistance of the central abutment structure 343 is matched with the wear that needs to be borne, thereby further improving the service life of the ball head with the abutment structure.

[0054] In some embodiments, Figure 7 As shown, the outer surface of the abutment structure 300 includes an arc surface 350, the geometric center of the arc surface 350 coincides with the center of the ball head, so that the arc surface 350 forms a curved surface concentric with the surface of the ball head, so that during the relative rotation of the center of the ball and the ball head, the arc surface 350 can better fit with the wall of the ball seat, further reducing the wear of the abutment structure 300.

[0055] In some embodiments, Fig.14 As shown, the ball seat (first connection structure 110) has a ball head ( Figure 2 The open end 111 of the second connecting structure 210) has an opening 112, and the ball seat also has a deformation groove 113, which extends from the open end 111 to the center of the ball seat, so that the ball seat is more likely to produce elastic deformation when the ball head is installed and removed, further reducing the difficulty of installing and removing the ball head.

[0056] In some embodiments, Figure 1 As shown, the electronic device 20 can be a camera device, which can be any device capable of acquiring images. The graphics can be a static image or a dynamic image data stream. Exemplarily, the camera device can be a camera for taking static pictures or a camera for acquiring image data streams.

[0057] Exemplarily, the camera device includes a shell, a lens and a photosensitive chip, the lens can allow external light to enter the interior of the shell, and when the photosensitive chip obtains external light, it can form an image of a preset size according to the position where the light acts on itself and the intensity of the light at that position, the image includes multiple pixels, the position of each pixel corresponds to the position of the photosensitive chip, and the grayscale of the pixel is positively correlated with the intensity of the light acting on the corresponding position of the photosensitive chip, and each image is stored in sequence according to time sequence to form a dynamic image data stream; optionally, a light-transmitting sheet is arranged between the photosensitive chip and the lens, the light-transmitting sheet includes multiple areas, the position of each area corresponds to the area where the pixel is formed on the photosensitive chip, each area of ​​the light-transmitting sheet includes a red area, a green area and a blue area, respectively allowing red light, green light and blue light to pass through, so that each pixel in the image formed by the photosensitive chip includes a red block, a green block and a blue block, and the brightness of the three color blocks is positively correlated with the intensity of the corresponding color light acting on the corresponding photosensitive chip, thereby enabling the photosensitive chip to convert external light into a color image.

[0058] By applying the bracket device 10 to the camera device and rotating the connecting member 200 relative to the base 100, the connecting member 200 can drive the camera device to generate a rotational motion relative to the base 100, thereby adjusting the orientation of the lens of the camera device. Since the abutment structure 300 of the bracket device 10 can enable the ball head and the ball seat to form a more reliable interference fit, the posture adjustment of the lens of the camera device can be more precise, thereby making the adjustment of the camera range and the camera angle of the camera device more precise.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
