[0069] The projector can project the image or video signal on the computer, smart terminal and the like on the screen or wall to realize large screen display. In the related art, some brackets for installing the projector cannot rotate, which limits the use scenarios. Although some rotating brackets can rotate relatively, they have relatively complex rotating mechanisms and control mechanisms for controlling the rotating mechanisms, which causes the problem of complex structure and large size of the rotating bracket.

[0070] In view of this, the embodiments of the present application provide a rotating bracket, aiming to solve the problem of complex structure and large size of the existing rotating bracket.

[0071] The rotating bracket in the embodiments of the present application includes a first rotating member and an elastic member, which elastically abuts against the first rotating member to provide damping force when the first rotating member rotates relative to the shell, thereby realizing the rotation and control of the rotating bracket. Compared with the existing rotating bracket which needs to be provided with a relatively complex rotating mechanism and a control mechanism for controlling the rotating mechanism, the rotating bracket in the present application has a simpler structure. In addition, in the present application, the first mounting hole and the mounting slot communicating with the first mounting hole are arranged on the shell, the elastic member is arranged in the mounting slot and extends at least partially into the first mounting hole, and the first rotating member is arranged in the first mounting hole, and the part of the elastic member extending into the first mounting hole elastically abuts against the first rotating member, so that the rotating bracket in the present application has a more compact structure, which is conducive to reducing the size of the rotating bracket.

[0072] For the convenience of understanding, the rotating bracket and the projector in the present application will be further described below with reference to the accompanying drawings.

[0073] Please refer to Figures 1 to 13 The embodiments of the present application provide a rotating bracket 10, which includes a bracket assembly 100 and a chassis assembly 200 connected in rotation. Please refer to Figure 4 and Figure 10 The chassis assembly 200 includes a first rotating member 220, and the bracket assembly 100 includes a shell (for example, a plastic shell 110) and an elastic member 140. The shell is provided with a first mounting hole 1125 and a mounting slot 1126 communicating with the first mounting hole 1125, the elastic member 140 is arranged in the mounting slot 1126 and extends at least partially into the first mounting hole 1125, and the first rotating member 220 is arranged in the first mounting hole 1125, and the part of the elastic member 140 extending into the first mounting hole 1125 elastically abuts against the first rotating member 220 to provide damping force when the first rotating member 220 rotates relative to the shell.

[0074] The chassis assembly 200 in the embodiments of the present application comprises a first rotating member 220; the support assembly 100 comprises a housing and an elastic member 140. The elastic member 140 elastically abuts against the first rotating member 220 to provide a damping force when the first rotating member 220 rotates relative to the housing, so that the rotation and control of the rotating support 10 are realized. Compared with the existing rotating support, the rotating support 10 in the present application has a simpler structure of the rotating mechanism and the control mechanism for controlling the rotating mechanism. In addition, in the present application, the first mounting hole 1125 and the mounting groove 1126 in communication with the first mounting hole 1125 are arranged on the housing, the elastic member 140 is arranged in the mounting groove 1126 and extends at least partially into the first mounting hole 1125, and the first rotating member 220 is arranged in the first mounting hole 1125, and the part of the elastic member 140 extending into the first mounting hole 1125 elastically abuts against the first rotating member 220, so that the rotating support 10 in the present application has a more compact structure, which is conducive to reducing the volume of the rotating support 10.

[0075] In some embodiments of the present application, the first rotating member 220 comprises a gear disc, the surface of the gear disc has a plurality of tooth portions 2221, a groove is formed between two adjacent tooth portions 2221, and the part of the elastic member 140 extending into the first mounting hole 1125 is located in the groove. In this embodiment, the gear disc is arranged to facilitate increasing the damping force when the first rotating member rotates relative to the housing, improving the hand feeling of the first rotating member during rotation, and improving the control accuracy of the rotation angle of the first rotating member.

[0076] Further, the elastic member 140 is an elastic sheet, please refer to Figure 10 and Figure 13 The elastic sheet comprises a pair of sliding ends 142 arranged oppositely and a V-shaped convex portion 141 connecting the pair of sliding ends 142, and the V-shaped convex portion 141 extends into the groove; each sliding end 142 elastically abuts against the wall surface of the mounting groove 1126, for example, each sliding end 142 elastically abuts against the bottom surface 1126a of the mounting groove 1126. In this way, the damping force when the first rotating member 220 rotates relative to the housing is further increased, the hand feeling of the first rotating member 220 during rotation is improved, and the control accuracy of the rotation angle of the first rotating member 220 is improved.

[0077] In the embodiment, when the gear plate rotates relative to the shell, the gear plate extrudes the "V"-shaped protrusion 141, the "V"-shaped protrusion 141 moves towards the direction close to the mounting groove 1126, the pair of sliding ends 142 move along the wall surface of the mounting groove 1126 in the direction away from each other, after the tooth portion 2221 that is to be abutted by the "V"-shaped protrusion 141 passes the "V"-shaped protrusion 141 in the rotating direction, the elastic member restores under the action of the elastic force of itself, and the "V"-shaped protrusion 141 is embedded into the other groove arranged adjacently under the elastic action. When the gear plate continues to rotate relative to the shell, the above process is repeated, which will not be described herein.

[0078] In some embodiments of the present application, the mounting groove 1126 includes a communication section in communication with the first mounting hole 1125, and a pair of side walls of the communication section is in the shape of "8", and the end of the "V"-shaped protrusion 141 away from the gear plate is in sliding abutment with the pair of side walls. In this way, the mounting precision of the elastic member 140 is improved, and the working stability of the elastic member 140 is improved.

[0079] In some embodiments of the present application, in the thickness direction of the gear plate, the gear plate includes a circular truncated cone portion 221 and a toothed disc portion 222 connected to each other, the diameter of the circular truncated cone portion 221 is greater than the diameter of the toothed disc portion 222, a plurality of tooth portions 2221 are arranged on the toothed disc portion 222, and the shell is provided with a blocking portion matched with the circular truncated cone portion 221, and the blocking portion is used for blocking the gear plate from moving in the direction perpendicular to the rotating direction of the gear plate. In the embodiment, by arranging that the gear plate includes the circular truncated cone portion 221 and the toothed disc portion 222 connected to each other, the diameter of the circular truncated cone portion 221 is greater than the diameter of the toothed disc portion 222, and the shell is provided with the blocking portion matched with the circular truncated cone portion 221 and used for blocking the gear plate from moving in the direction perpendicular to the rotating direction of the gear plate, the structural stability of the rotating support 10 in the present application is further improved.

[0080] As shown in Figure 9 for example, the blocking portion on the shell includes an outer blocking portion (for example, a stepped portion formed on the outer shell 112 close to the edge of the first mounting hole 1125, which is in abutment with the side of the circular truncated cone portion close to the tooth portion) on the outer shell 112, which is used for limiting the downward movement of the gear plate. The blocking portion can also be a reinforcing rib or a limiting block formed on the side of the inner shell 111 facing the outer shell 112, or a reinforcing rib or a limiting block formed on the side of the support member 120 (which will be described below) facing the outer shell 112, which is used for limiting the upward movement of the gear plate, which will not be limited herein.

[0081] In some embodiments of the present application, please refer to Figure 4 and Figure 9The first mounting hole 1125 is arranged on the bottom surface of the shell. The bottom disc assembly 200 further comprises a fixed bottom disc 210, which is fixedly connected with the tooth disc part 222. The fixed bottom disc 210 is arranged on the bottom surface of the shell and covers the first mounting hole 1125. In this way, the appearance quality of the shell can be improved, and foreign matters or dust can be prevented from entering the interior of the shell through the first mounting hole 1125, thereby improving the stability of the rotating support 10.

[0082] In some embodiments of the present application, please refer to Figure 9 The bottom disc assembly 200 further comprises a wear-resistant part 230, which is used to prevent the bottom disc assembly 200 from being seriously worn when the bottom disc assembly 200 rotates relative to the support assembly 100. For example, the wear-resistant part 230 comprises a first wear-resistant part 231, which is a wear-resistant sheet. The first wear-resistant part 231 is arranged between the fixed bottom disc 210 and the shell. For example, the first wear-resistant part 231 is arranged between the fixed bottom disc 210 and the outer shell 112. In this way, the problem of wear between the fixed bottom disc 210 and the shell caused by direct contact can be improved when the fixed bottom disc 210 rotates relative to the shell.

[0083] In some embodiments of the present application, the wear-resistant part 230 further comprises a second wear-resistant part 232, which is a wear-resistant sheet. The second wear-resistant part 232 is arranged between the circular truncated cone part 221 and the shell. For example, the second wear-resistant part 232 is arranged between the fixed bottom disc 210 and the outer shell 112 (i.e., the second wear-resistant part 232 is arranged on the stepped part formed at the edge of the first mounting hole 1125). In this way, the problem of wear between the circular truncated cone part 221 and the shell caused by direct contact can be improved when the circular truncated cone part 221 rotates relative to the shell.

[0084] In some embodiments of the present application, please refer to Figure 3 、 Figure 4 and Figure 9 The shell is a plastic shell 110, and the support assembly 100 comprises the plastic shell 110 and a support part 120. The plastic shell 110 comprises a pair of cantilever parts 113 arranged oppositely and a connecting part 114 connected with the pair of cantilever parts 113. For example, the connecting part 114 is connected with the same end of the pair of cantilever parts 113. The end of each cantilever part 113 away from the connecting part 114 is used to be connected with a to-be-connected part. An installation cavity is arranged in each cantilever part 113. The support part 120 is arranged in the installation cavity and extends along the length direction of the cantilever part 113.

[0085] It should be noted that the plastic shell (for example, the cantilever support made of plastic material) has the problem of deformation of the cantilever, resulting in poor stability of the product. The support assembly 100 in the embodiment of the present application increases the support 120, and sets the mounting cavity in the cantilever portion 113, the support 120 is arranged in the mounting cavity, and the support 120 extends along the length direction (i.e. the vertical direction in Figure 1 ) of the cantilever portion 113, thereby increasing the strength of the cantilever portion 113 provided with the support 120, and effectively improving the problem of deformation of the cantilever portion 113 in the support assembly 100 during use. At the same time, the support 120 is arranged in the cantilever portion 113, which is beneficial to improve the compactness of the structure of the support assembly 100, and does not affect the appearance quality of the support assembly 100.

[0086] It should be noted that the to-be-connected member includes but is not limited to the projection body 500, and can also be other devices that need to be supported, which is not limited herein. Unless otherwise specified, the to-be-connected member in the present application is taken as the projection body 500 for example. Exemplarily, the support assembly 100 is rotationally connected with the projection body 500, so that the projection body 500 can rotate relative to the support assembly 100, thereby flexibly adjusting the projection direction of the projection body 500.

[0087] The support assembly 100 in the embodiment of the present application increases the support 120, and sets the mounting cavity in the cantilever portion 113, the support 120 is arranged in the mounting cavity, and the support 120 extends along the length direction (i.e. the vertical direction in Figure 9 ) of the cantilever portion 113, thereby increasing the strength of the cantilever portion 113 provided with the support 120, and effectively improving the problem of deformation of the cantilever portion 113 in the support assembly 100 during use. At the same time, the support 120 is arranged in the cantilever portion 113, which is beneficial to improve the compactness of the structure of the support assembly 100, and does not affect the appearance quality of the support assembly 100.

[0088] In some embodiments of the present application, the orthographic projection of the plastic shell 110 is in the shape of the letter "U", which can also be understood as that the appearance profile of the plastic shell 110 is generally in the shape of the letter "U". In this way, it is beneficial to increase the appearance quality of the support assembly 100. In addition, when the support assembly 100 is used for a projector, it is beneficial to improve the installation convenience of the projection body, and can avoid interference between the projection body and the support assembly 100 when the projection body rotates in a larger angle range.

[0089] In some embodiments of the present application, the support 120 extends from the connecting portion 114 to one end of the cantilever portion 113 away from the connecting portion 114. Exemplarily, please refer to Figure 4 and Figure 9The support assembly 100 comprises two support pieces 120, one support piece 120 is arranged in each cantilever part 113, and the two support pieces 120 are symmetrically arranged in the pair of cantilever parts 113. Further, the support piece 120 is in the shape of the letter "L". In this way, the manufacturing process of the support piece 120 is simplified, the connection area between the support piece 120 and the plastic shell 110 is increased, and the problem that the cantilever part 113 in the support assembly 100 is easily deformed during use is further improved.

[0090] In some embodiments of the present application, the support piece 120 is fixedly connected with the plastic shell 110. In this way, the connection stability between the support piece 120 and the plastic shell 110 is increased.

[0091] For example, referring to Figure 11 and Figure 12 , a fixing hole 121 can be arranged on the support piece 120, a positioning part 1117 is arranged on the plastic shell 110, for example, the positioning part 1117 is a positioning column, a threaded hole is arranged in the positioning column, and the locking piece 300 is threadedly connected with the threaded hole on the plastic shell 110 through the fixing hole 121 on the support piece 120, so as to fix the support piece 120 on the plastic shell 110. In other embodiments of the present application, the support piece 120 can also be fixed on the plastic shell 110 by clamping or gluing, which is not limited herein.

[0092] In some embodiments of the present application, referring again to Figure 4 and Figure 9 , the plastic shell 110 comprises an inner shell 111 and an outer shell 112, the inner shell 111 is arranged on the inner side of the outer shell 112, the inner shell 111 comprises a pair of cantilever inner walls 1111 and an inner connecting wall 1112 connecting the pair of cantilever inner walls 1111. The outer shell 112 comprises a pair of cantilever outer walls 1121 and an outer connecting wall 1122 connecting the pair of cantilever outer walls 1121, each cantilever part 113 comprises the cantilever inner wall 1111 and the cantilever outer wall 1121, the connecting part 114 comprises the inner connecting wall 1112 and the outer connecting wall 1122, and the mounting cavity is arranged between the cantilever inner wall 1111 and the cantilever outer wall 1121. Further, the mounting cavity is arranged between the cantilever inner wall 1111 and the cantilever outer wall 1121 and between the inner connecting wall 1112 and the outer connecting wall 1122, that is, the mounting cavities in the cantilever part 113 and the connecting part 114 are communicated with each other. In this way, the installation convenience of the support piece 120 is improved, and the installation and maintenance of the parts in the plastic shell 110 are facilitated.

[0093] In some embodiments of the present application, the inner shell 111 is a one-piece structure. For example, the inner shell 111 is a one-piece structure integrally formed by a plastic material through an injection molding process. In this way, the overall mechanical properties of the inner shell 111 and the production efficiency are improved, and the assembly efficiency of the support assembly 100 is improved.

[0094] In some embodiments of the present application, the outer shell 112 is a one-piece structure. For example, the outer shell 112 is a one-piece structure integrally formed by a plastic material through an injection molding process. In this way, the overall mechanical properties of the outer shell 112 and the production efficiency are improved, and the assembly efficiency of the support assembly 100 is improved.

[0095] In some embodiments of the present application, the outer shell 112 is provided with a plurality of first clamping portions 1123, and the inner shell 111 is provided with a plurality of second clamping portions 1113 matched with the first clamping portions 1123. In this way, by providing the first clamping portions 1123 and the second clamping portions 1113 matched with each other on the outer shell 112 and the inner shell 111, the structural strength of the plastic shell 110 is improved.

[0096] For example, referring to Figure 4 , Figure 9 and Figure 12 , the outer shell 112 is provided with a plurality of first clamping portions 1123, and the plurality of first clamping portions 1123 are arranged on the side of the outer shell 112 facing the inner shell 111, for example, the plurality of first clamping portions 1123 are close to the edge of the outer shell 112. For example, the plurality of first clamping portions 1123 are distributed along the frame line of the outer shell 112. Correspondingly, the inner shell 111 is provided with a plurality of second clamping portions 1113, and the plurality of second clamping portions 1113 are arranged on the side of the inner shell 111 facing the outer shell 112, and the plurality of second clamping portions 1113 are close to the edge of the inner shell 111 and are distributed along the frame line of the inner shell 111, and the plurality of first clamping portions 1123 and the plurality of second clamping portions 1113 are arranged one by one. In this way, the stability of the plastic shell 110 is further improved.

[0097] In some embodiments of the present application, the inner shell 111 is in sliding connection with the outer shell 112, and the first clasp part 1123 and the corresponding second clasp part 1113 are buckled or unbuckled during the relative sliding of the inner shell 111 and the outer shell 112. It should be noted that in the related art, the inner shell 111 and the outer shell 112 are installed by pressing clasp, and if the buckling amount of the clasp is small, the connection between the inner shell 111 and the outer shell 112 is easy to crack; if the buckling amount of the clasp is large, the installer needs to exert a large force to connect the inner shell 111 and the outer shell 112, which leads to difficult installation, and the clasp is easy to break, which leads to poor stability of the support assembly 100 and is not conducive to installation and maintenance. In this embodiment, the first clasp part 1123 and the corresponding second clasp part 1113 are buckled or unbuckled during the relative sliding of the inner shell 111 and the outer shell 112, which is conducive to improving the assembly efficiency of the inner shell 111 and the outer shell 112, and improving the stability of the plastic shell 110. It should be noted that the buckling amount of the clasp in the present application refers to the size of the mutual embedding or overlapping of the first clasp part and the second clasp part (i.e., the male buckle and the female buckle) when buckled.

[0098] For example, referring to Figure 9 The edge of the inner shell 111 is provided with a plurality of second clasp parts 1113, for example, the second clasp part 1113 is a second clamping block, and the first clamping groove 1114 is formed between the second clamping block and the bottom surface of the inner shell 111. The edge of the outer shell 112 is provided with a plurality of first clasp parts 1123, for example, the first clasp part 1123 is a second clamping block, and the first clamping block moves along the sliding direction (i.e., the assembly direction of the outer shell 112 on the inner shell 111) to enter the corresponding first clamping groove 1114 to make the first clamping block and the corresponding second clamping block buckle, or the first clamping block moves along the sliding direction (i.e., the disassembly direction of the outer shell 112 on the inner shell 111) to be separated from the corresponding first clamping groove 1114 to make the first clamping block and the corresponding second clamping block unbuckle.

For example, the second guide portion 1116 is a guide rib, the third guide portion 1124 is a guide rib, the second guide portion 1116 can slide along the third guide portion 1124, so that the outer shell 112 is slidingly connected or assembled with the inner shell 111. In this way, the assembly precision of the outer shell 112 can be further improved.

[0102] In some embodiments of the present application, the support 120 is provided with a first avoiding hole 123 for avoiding the rotating shaft.
