[0007] The positioning seat has a first position and a second position during rotation relative to the support assembly. When the positioning seat is in the first position, the first support part is facing upward, and the height of the first support part in the second direction is H1.

[0008] When the positioning seat is in the second position, the second support portion is facing upwards, and the height of the second support portion in the second direction is H2;

[0009] Where H1 is less than H2;

[0010] The first direction and the second direction are perpendicular to each other.

[0011] In one embodiment, the positioning base further includes two connecting arms respectively connected to opposite sides of the base body along the first direction, and the two connecting arms and the first support portion form a receiving groove for partially accommodating the projector;

[0018] In one embodiment, the projector bracket further includes a damping shaft disposed along the first direction, and the connecting arm is rotatably connected to the corresponding connecting seat via the corresponding damping shaft.

[0019] In one embodiment, the support assembly includes two legs arranged at an angle;

[0020] The connecting arm has an outer end and an inner end that are disposed opposite to each other along the first direction;

At this time, the second support part is facing upwards, and a projector with a lower height can be placed on the second support part in the higher position and connected to the base. In this way, a projector with a lower height can be installed using the projector bracket. It can be understood that this projector bracket can be used to install projectors of different heights, which is beneficial to ensure that the images projected by projectors of different heights are roughly at the same height. It can be seen that this projector bracket can be applied to more application scenarios, thus broadening the application range of the projector bracket. Attached Figure Description

[0042] Figure 1 and Figure 2 The diagrams show the structure of the projector bracket 10 in one embodiment of this application when the positioning seat 110 is in the first position and the second position, respectively.

[0043] Please see Figure 1 and Figure 2 The projector bracket 10 provided in one embodiment of this application is used to connect a projector 20. The projector bracket 10 includes a positioning base 110 and a support component 120.

[0044] The support component 120 refers to the component that can support the positioning base 110. The support component 120 can be placed on a horizontal table, and then the projector 20 can be detachably connected to the base 111, so that the image can be projected directly in front using the projector 20.

[0045] The positioning seat 110 is rotatably connected to the support assembly 120 about an axis parallel to the first direction F1, and the positioning seat 110 includes a base 111 for detachable connection with the projector 20. The base 111 includes a first support portion 1111 and a second support portion 1112 disposed opposite to each other. The positioning seat 110 has a first position and a second position during rotation relative to the support assembly 120. When the positioning seat 110 is in the first position, the first support portion 1111 is disposed upward, and the height of the first support portion 1111 in the second direction F2 is H1. When the positioning seat 110 is in the second position, the second support portion 1112 is disposed upward, and the height of the second support portion 1112 in the second direction F2 is H2, where H1 is less than H2.

[0046] The first direction F1 and the second direction F2 are perpendicular to each other. The first direction F1 can be parallel to the horizontal direction, and the second direction F2 can be parallel to the direction of gravity of the projector bracket 10, that is, parallel to the height direction of the projector 20.

[0047] Since H1 is less than H2, when using the projector bracket 10, the positioning seat 110 can rotate relative to the support assembly 120 about an axis parallel to the first direction F1, and the positioning seat 110 is in the first position. At this time, the first support part 1111 is facing upwards, and a projector 20 with a higher height can be placed on the first support part 1111 in the lower position, and the projector 20 is connected to the base body 111. In this way, a projector 20 with a higher height can be installed using the projector bracket 10. Alternatively, the positioning seat 110 can rotate relative to the support assembly 120 about an axis parallel to the first direction F1, and the positioning seat 110 is in the second position. At this time, the second support part 1112 is facing upwards, and a projector 20 with a lower height can be placed on the second support part 1112 in the higher position, and the projector 20 is connected to the base body 111. In this way, a projector 20 with a lower height can be installed using the projector bracket 10. It is understandable that the projector stand 10 can be used to install projectors 20 at different heights, which helps to ensure that the images projected by projectors 20 at different heights are roughly at the same height. It can be seen that the projector stand 10 can be used in more application scenarios and can broaden the application range of the projector stand 10.

[0048] In some embodiments, please refer to Figure 3 and Figure 4The projector 20 includes a vertical projector 21 and a horizontal projector 22. The vertical projector 21 is taller than the horizontal projector 22. When the positioning base 110 is in the first position, the first support portion 1111 faces upward, and the vertical projector 21 can be placed on the first support portion 1111. When the positioning base 110 is in the second position, the second support portion 1112 faces upward, and the horizontal projector 22 can be placed on the second support portion 1112.

[0049] In some embodiments, please refer to Figure 1 The positioning base 110 includes two connecting arms 112 respectively connected to opposite sides of the base body 111 along the first direction F1. The two connecting arms 112 and the first support portion 1111 form a receiving groove 113 for partially accommodating the projector 20. The end of the connecting arm 112 away from the base body 111 is rotatably connected to the support assembly 120 about an axis parallel to the first direction F1. Specifically, the connecting arm 112 is arranged approximately perpendicular to the base body 111, and the connecting arm 112 has a first end and a second end arranged opposite to each other. The first end of the connecting arm 112 is connected to the base body 111, and the second end of the connecting arm 112 is rotatably connected to the support assembly 120 about an axis parallel to the first direction F1.

[0050] Thus, when the dimension of the projector 20 along the first direction F1 is smaller than the dimension of the receiving groove 113 along the first direction F1, the positioning seat 110 can be in the first position, the projector 20 can be placed on the first support 1111, and part of the projector 20 can be housed in the receiving groove 113 (in conjunction with...). Figure 1 and Figure 3 (For illustrative purposes only), the sidewall of the receiving groove 113 can be used to limit the movement of the projector 20 along the first direction F1, thereby lowering the installation height of the projector 20 while also fixing it more stably. For example, if the dimension of the vertical projector 21 along the first direction F1 is smaller than the dimension of the receiving groove 113 along the first direction F1, the vertical projector 21 can be partially housed in the receiving groove 113 to better limit and fix the vertical projector 21.

[0051] In some embodiments, please refer to Figure 5 The base 111 has a through mounting hole 1115, and the positioning base 110 also includes a mounting base 114 rotatably disposed in the mounting hole 1115. The mounting base 114 is configured to fix the projector 20 to the first support 1111 or the second support 1112.

[0052] Since the positioning base 110 needs to be rotated during the installation of projectors 20 at different heights to switch between the first and second positions, the mounting base 114, which can rotate relative to the base body 111, can also be flipped as needed, so that the connection point of the mounting base 114 with the corresponding projector 20 is flipped upwards, so that the mounting base 114 can be detachably connected to the bottom of the corresponding projector 20, which can improve the convenience of the projector bracket 10.

[0053] The mounting base 114 can be rotated to flip it upwards so as to connect to the projector 20 on the first support 1111 or the second support 1112.

[0054] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 5 The mounting base 114 includes a flip-up portion 1141 and a first screw 1142. The first screw 1142 is disposed on the flip-up portion 1141, and the threaded portion 11423 of the first screw 1142 protrudes from one side of the flip-up portion 1141 for connection with the projector 20.

[0055] Understandably, the bottom of the projector 20 has a threaded hole that is compatible with the threaded portion 11423 so that the threaded portion 11423 can be connected to the projector 20.

[0056] Thus, by rotating the mounting base 114, the threaded portion 11423 of the first screw 1142 of the mounting base 114 can be flipped upwards to connect with the projector 20 on the first support portion 1111 or the second support portion 1112.

[0057] Of course, this application is not limited to this. The first screw 1142 can also be replaced with other components that can be detachably connected to the projector 20, such as a snap-fit ​​component that snaps into the projector 20.

[0058] In some embodiments, the mounting base 114 is detachably connected to the base body 111. This allows for easy replacement or removal of the mounting base 114 as needed.

[0059] In this embodiment, the positioning base 110 further includes a pin 115, and the mounting base 114 is provided with a first pin hole 1144 adapted to the pin 115. Optionally, the first pin hole 1144 is provided on the flip part 1141, and the base body 111 is provided with a second pin hole 1113 adapted to the pin 115. The second pin hole 1113 is correspondingly provided with the first pin hole 1144. The pin 115 is inserted into the first pin hole 1144 and the second pin hole 1113 respectively, so that the mounting base 114 can rotate relative to the base body 111 around the pin 115. At the same time, it is also convenient to disassemble and assemble the mounting base 114.

[0060] Optionally, when the positioning seat 110 is in the first or second position, the pin 115 can be inserted into the first pin hole 1144 and the second pin hole 1113 along the third direction F3, so that the mounting seat 114 can rotate relative to the seat body 111 about the axis of the third direction F3. The third direction F3 intersects with the first direction F1, and the third direction F3 is perpendicular to the second direction F2. Optionally, the first direction F1, the second direction F2, and the third direction F3 are all perpendicular to each other. Specifically, the second direction F2 is parallel to the height direction (or thickness direction) of the projector 20, one of the first direction F1 and the third direction F3 is parallel to the length direction of the projector 20, and the other of the first direction F1 and the third direction F3 is parallel to the width direction of the projector 20.

[0061] Optionally, the positioning base 110 further includes two pins 115. The flip portion 1141 of the mounting base 114 is provided with first pin holes 1144 on opposite sides. The base body 111 includes a surrounding portion 1114 surrounding the mounting base 114. The mounting hole 1115 passes through the surrounding portion 1114. The surrounding portion 1114 is provided with second pin holes 1113 on opposite sides. Each pin 115 is inserted into the first pin hole 1144 and the second pin hole 1113 on the same side, which can better enable the mounting base 114 to rotate relative to the base body 111 around the pin 115.

[0062] In some embodiments, the mounting base 114 further includes an annular washer 1143. The flip portion 1141 has a through hole 11411 for the first screw 1142 to pass through. The annular washer 1143 is sleeved on one end of the first screw 1142 that passes through the through hole 11411. The portion of the first screw 1142 that passes through the annular washer 1143 is provided in an interference fit within the annular washer 1143 to fix the first screw 1142 on the flip portion 1141. The portion of the first screw 1142 that passes through the annular washer 1143 is used for detachable connection to the bottom of the corresponding projector 20.

[0063] Optionally, the first screw 1142 includes a head 11421, a through portion 11422, and a threaded portion 11423 connected sequentially along the second direction F2. The radial dimension of the head 11421 is larger than the radial dimension of the through portion 11422 and also larger than the radial dimension of the threaded portion 11423. The head 11421 abuts against the side of the flip portion 1141 near the second support portion 1112 along the second direction F2. The through portion 11422 and the threaded portion 11423 pass through the through hole 11411. The portion of the through portion 11422 passing through the through hole 11411 is interference-fitted into the annular washer 1143. The threaded portion 11423 extends out of the annular washer 1143 so as to be threadedly connected to the bottom of the corresponding projector 20.

[0064] Of course, this application is not limited to this. Other methods can also be used to fix the first screw 1142 to the flip part 1141, which can detachably connect the mounting base 114 to the corresponding projector 20, while also reducing the disassembly and assembly of parts and improving the assembly efficiency of the projector 20.

[0065] In some embodiments, the support assembly 120 includes a leg 121, the leg 121 including two connecting seats 1211 corresponding to the connecting arm 112, and the connecting arm 112 is rotatably connected to the corresponding connecting seat 1211 about an axis parallel to the first direction F1.

[0066] The support leg 121 is a component that can support the positioning base 110. The support leg 121, away from the positioning base 110, can have a support portion that can be placed flat on a table.

[0067] This allows the positioning seat 110 to rotate more effectively relative to the support assembly 120 about an axis parallel to the first direction F1, and also helps the support assembly 120 to better support the positioning seat 110.

[0068] In some embodiments, the projector bracket 10 further includes a damping shaft 130 disposed along a first direction F1, and the connecting arm 112 is rotatably connected to the corresponding connecting seat 1211 via the corresponding damping shaft 130.

[0069] The support leg 121 rotates via the damping pivot 130 and can stop at any position, making it easier to adjust the angle of the projector 20 relative to the horizontal plane.

[0070] In some embodiments, the support assembly 120 includes two legs 121 arranged at an angle, and the connecting arm 112 has an outer end 1121 and an inner end 1122 (e.g., ...) arranged opposite each other along a first direction F1. Figure 5 As shown), the two connecting seats 1211 of one leg 121 are rotatably connected to the inner ends 1122 of the two connecting arms 112 via corresponding damping shafts 130, and the two connecting seats 1211 of the other leg 121 are rotatably connected to the outer ends 1121 of the two connecting arms 112 via corresponding damping shafts 130 (in combination with...). Figure 1 (To understand).

[0071] This configuration allows the two legs 121 to rotate relative to the two leg 121 positioning seats 110, so as to adjust the included angle between the two legs 121 and thus adjust the height of the positioning seats 110.

[0072] In some embodiments, please refer to Figure 6The damping shaft 130 includes a shaft body 131, and a first connecting ring 132 and a second connecting ring 133 sleeved on the shaft body 131. The first connecting ring 132 and the second connecting ring 133 are respectively in rotational frictional engagement with the shaft body 131. The first connecting ring 132 is detachably connected to the end of the connecting arm 112 away from the seat 111. Optionally, the end of the first connecting ring 132 away from the seat 111 can be connected by a plurality of second screws 141 (in combination). Figure 5 (For understanding purposes) Specifically, the first connecting ring 132 is provided with a plurality of first threaded holes 134 adapted to the second screw 141, and the end of the connecting arm 112 away from the seat 111 is provided with a plurality of second threaded holes 1123 adapted to the second screw 141. The second screw 141 passes through the corresponding first threaded holes 134 and the corresponding second threaded holes 1123 to connect the first connecting ring 132 and the connecting arm 112.

[0073] The second connecting ring 133 is detachably connected to the corresponding connecting seat 1211, specifically as follows: Figure 7 In the illustrated embodiment, the second connecting ring 133 and the corresponding connecting seat 1211 can be connected by a plurality of third screws 142. Specifically, the second connecting ring 133 is provided with a plurality of third threaded holes 135 adapted to the third screws 142, and the connecting seat 1211 is provided with a plurality of fourth threaded holes adapted to the third screws 142. The third screws 142 pass through the corresponding third threaded holes 135 and the corresponding fourth threaded holes to connect the second connecting ring 133 and the corresponding connecting seat 1211.

[0074] Thus, on the one hand, the positioning seat 110 can rotate well relative to the support assembly 120 via the damping pivot 130 to adjust the angle of the positioning seat 110 relative to the horizontal plane, and it is also convenient to install projectors 20 at different heights on the positioning seat 110. On the other hand, the two legs 121 of the support assembly 120 can rotate well relative to the positioning seat 110 via the damping pivot 130 to adjust the angle between the two legs 121, thereby adjusting the height of the positioning seat 110 and the projector 20.

[0075] In some embodiments, the projector bracket 10 further includes a decorative element 150. The connecting seat 1211 has an installation channel with openings at both ends and extending along the first direction F1, which facilitates the damping shaft 130 to pass into the installation channel and also facilitates the connection of the second connecting ring 133 of the damping shaft 130 with the corresponding connecting seat 1211. The decorative element 150 is disposed at the end of the connecting seat 1211 away from the connecting arm 112 to close the outer opening of the installation channel. The decorative element 150 can be used to cover the damping shaft 130 and other components, which serves both aesthetic and protective purposes.

[0076] In some embodiments, please refer to Figure 8The support leg 121 also includes a flat portion 1212 connected between two connecting seats 1211 and set at an angle to the connecting seats 1211, and the flat portion 1212 is provided with an anti-slip layer 1214.

[0077] The support leg 121 can be placed flat on the table using the flat part 1212. The anti-slip layer 1214 makes it less likely for the support leg 121 to slide relative to the table, which helps the flat part 1212 to be placed more stably on the table.

[0078] The anti-slip layer 1214 can be silicone rubber or other components that can increase the friction between the flat part 1212 and the tabletop, without specific limitations.

[0079] In some embodiments, each leg 121 further includes two connecting parts corresponding to the connecting seat 1211 and two support rods 1213 corresponding to the connecting parts. The two connecting parts (not shown in the figure) are respectively connected to the two ends of the flat part 1212, and each support rod 1213 is connected between the corresponding connecting part and the connecting seat 1211.

[0080] In some embodiments, the connector 1211 has a first insertion hole for inserting the support rod 1213, the first insertion hole being configured to restrict the rotation of the support rod 1213.

[0081] The first insertion hole can be a non-circular hole, and the support rod 1213 can be a structure corresponding to this non-circular hole. This allows the first insertion hole to restrict the rotation of the support rod 1213, improving the reliability of the support leg 121, and thus facilitating more stable support of the positioning seat 110 and the projector 20 using the support leg 121. For example, the support rod 1213 can be a flat rectangular structure, and the first insertion hole can be a flat rectangular hole corresponding to this flat rectangular structure.

[0082] In some embodiments, the support rod 1213 has a flat rectangular section 12131 that is inserted into the first insertion hole. An adhesive layer is provided between the outer wall of the flat rectangular section 12131 and the inner wall of the first insertion hole, which can make the support rod 1213 more firmly connected to the connecting seat 1211.

[0083] In some embodiments, the anti-slip layer 1214 is sleeved on the flat portion 1212 and extends to the connecting portion and part of the support rod 1213.

[0084] This design allows for better utilization of the anti-slip layer 1214 to improve the friction and stability of the outriggers 121.

[0085] In some embodiments, the end of the support rod 1213 connected to the connecting part is provided with a knurled section 12132, and the end of the connecting part near the support rod 1213 is provided with a second insertion hole for the knurled section 12132 to be inserted. An adhesive layer is provided between the outer wall of the knurled section 12132 and the inner wall of the second insertion hole, so that the support rod 1213 is more firmly connected to the connecting part.

[0086] When the projector bracket 10 of this application is in use, the positioning seat 110 can rotate relative to the support assembly 120 via the damping pivot 130 about an axis parallel to the first direction F1, so that the positioning seat 110 is in the first position, at which time the first support part 1111 is set upward, and the vertical projector 21 can be placed on the first support part 1111; or the positioning seat 110 can be set in the second position, at which time the second support part 1112 is set upward, and the horizontal projector 22 can be placed on the second support part 1112; thus, the projector bracket 10 can be adapted to projectors 20 of different heights, so that the projector bracket 10 can be adapted to more application scenarios, thus broadening the application range of the projector bracket 10.

[0087] The positioning seat 110 can rotate relative to the support assembly 120 about an axis parallel to the first direction F1. The angle of the positioning seat 110 relative to the horizontal plane can be adjusted as needed, thereby adjusting the angle of the projector 20 relative to the horizontal plane.

[0088] The two legs 121 of the support assembly 120 can also rotate relative to the positioning seat 110 via the damping pivot 130 about an axis parallel to the first direction F1, thereby adjusting the angle between the two legs 121 and thus adjusting the height of the positioning seat 110 and the projector 20.

[0089] The projection device provided in one embodiment of this application includes the projector bracket 10 described above, and also includes a projector 20. The projector 20 is detachably mounted on the projector bracket 10, so that different projectors 20 can be installed on the projector bracket 10 as needed. For example, a vertical projector 21 or a horizontal projector 22 can be installed on the projector bracket 10.

[0090] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0091] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
