Description

Technical Field

[0001] This application relates to the field of display screen curvature adjustment, and more particularly to a curvature adjustment mechanism. Background Technology

[0002] A curved screen consists of multiple display units and a cabinet located behind the display units. The front surface of the cabinet is curved. Multiple display units are spliced ​​onto the curved surface formed by the front surface of the cabinet to form a curved screen. Nowadays, the curvature of a curved screen is generally adjusted by a curvature adjustment mechanism on the back of the screen.

[0003] Currently, the curvature adjustment mechanism on the market generally includes a first splicing body and a second splicing body. The first splicing body is equipped with an arc-shaped slider, and the second splicing body is equipped with an extension block. The extension block has a groove that cooperates with the arc-shaped slider. When the arc-shaped slider passes through the groove, the second splicing block slides and cooperates with the first splicing block. Thus, when the curvature of the display screen needs to be changed, the curvature of the display screen can be changed through the relative sliding between the first splicing block and the second splicing block.

[0004] While the aforementioned technologies achieve the goal of adjusting the curvature of the display screen, the sliding distance of the first and second splicing bodies during the sliding process is difficult to control, making it difficult to precisely adjust the curvature of the display screen. Summary of the Invention

[0005] In order to precisely adjust the curvature of the display screen, this application provides a curvature adjustment mechanism.

[0006] The arc adjustment mechanism provided in this application adopts the following technical solution:

[0007] An arc adjustment mechanism includes a drive rod, two sets of adjustment housings, two sets of adjustment components, and a locking component. The two adjustment housings are respectively disposed at both ends of the drive rod. Each adjustment housing includes a first housing part and a second housing part. The first housing part and the second housing part are slidably engaged. The two first housing parts are rotatably connected to both ends of the drive rod.

[0008] The two adjustment components are respectively disposed in two adjustment housings. Each adjustment component includes an arc-shaped rack and an adjustment gear. The arc-shaped rack is fixedly disposed in the second housing part, and the adjustment gear is rotatably disposed in the first housing part. The adjustment gear meshes with the arc-shaped rack, and the two adjustment gears rotate when the drive rod rotates.

[0009] The locking assembly includes a locking block, and the second housing portion has a locking groove. The locking block passes through and slides into the locking groove. The locking block is rotatably connected to any adjusting gear. When the locking assembly is locked, the locking block and the locking groove are pressed together and fixed. The first housing portion and the second housing portion are also pressed together and fixed.

[0010] By adopting the above technical solution, when the curvature of the curved display screen needs to be adjusted, the drive rod rotates, and the two ends of the drive rod drive the two adjusting gears to rotate simultaneously. When the two adjusting gears rotate simultaneously, they drive the two arc-shaped racks to slide simultaneously. The sliding of the two arc-shaped racks drives the two second housing parts to slide towards or away from the first housing part, thereby changing the distance between the far ends of the first housing part and the second housing part, thus changing the angle of the curved display screen. At the same time, through the meshing between the adjusting gears and the arc-shaped racks, the sliding distance of the second housing part relative to the first housing part is predictable, making it easier to accurately adjust the curvature of the curved display screen. This improves the problem that although the purpose of adjusting the curvature of the display screen is achieved, the sliding distance of the first and second splicing bodies is not easy to control, thus making it difficult to accurately adjust the curvature of the display screen.

[0011] At the same time, when the curvature of the curved display screen is adjusted, the locking block and the locking groove are pressed together and fixed, so that the first housing part and the second housing part are pressed together and fixed, so that the first housing part and the second housing part are not easy to slip relative to each other, thereby completing the locking of the adjustment mechanism.

[0012] Optionally, the drive rod includes a main body and a first rod body, the first rod body and the main body are slidably engaged, the main body rotates, the first rod body rotates, the first rod body is rotatably connected to a first housing and rotatably connected to a locking block, and the first rod body is coaxially fixed with an adjusting gear.

[0013] The locking assembly further includes a drive sleeve disposed in an adjustment housing. The drive sleeve moves relative to the adjustment housing, the first rod portion slides toward or away from the main body portion, and the adjustment gear moves toward or away from the locking block. When the adjustment gear moves toward the locking block, the adjustment gear presses the locking block against and fixes it in the locking groove.

[0014] Optionally, the first rod body is provided with a drive groove, and the drive sleeve is fixedly provided with a drive protrusion. The drive protrusion passes through the drive groove and abuts against the drive groove body. When the drive sleeve moves relative to the adjusting housing, the drive protrusion drives the first rod body to move through the drive groove.

[0015] Optionally, a connecting sleeve is fixedly provided on one side of the first housing portion, and the driving sleeve passes through the connecting sleeve and is threadedly connected to the connecting sleeve. When the driving sleeve rotates relative to the connecting sleeve, the driving sleeve moves relative to the adjusting housing.

[0016] Optionally, the connecting sleeve has a through-hole in the middle and a through-groove on the outer circumferential surface of the connecting sleeve. The connecting hole and the limiting groove are connected. The first rod body passes through and rotatably engages with the connecting hole. The driving groove is connected with the limiting groove. The driving protrusion passes through the limiting groove and slides with the driving groove. When the driving sleeve rotates to a set position, the driving protrusion abuts against the groove body of the limiting groove.

[0017] Optionally, the drive rod further includes a second rod body portion, which is slidably engaged with one end of the main body portion away from the first rod body portion and rotatably connected to another first housing portion, and the second rod body portion is coaxially fixed with another adjusting gear;

[0018] The first rod body has a first rotating groove, the second rod body has a second rotating groove, and the drive rod has a plurality of through rotating holes. Each rotating hole is threaded with a rotating protrusion. Each rotating protrusion passes through the first rotating groove and the second rotating groove and abuts against the bottom of the first rotating groove and the second rotating groove, respectively. When each rotating protrusion rotates, the first rod body and the second rod body rotate. The width of the first rotating groove is greater than the diameter of the rotating protrusion.

[0019] Optionally, each of the two first housing parts is fixedly connected with a guide block, and each of the two second housing parts is provided with a guide groove in the shape of an arc. The two guide blocks are respectively inserted through and slidably engaged in the two guide grooves.

[0020] Optionally, each of the two first housing portions is engraved with a scale pointer, and each of the two second housing portions is engraved with an adjustment scale, wherein the value of the adjustment scale pointed to by the scale pointer is the curvature value of the curved screen.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. When the curvature of the curved display screen needs to be adjusted, the drive rod rotates, and the two ends of the drive rod drive the two adjusting gears to rotate simultaneously. When the two adjusting gears rotate simultaneously, they drive the two arc-shaped racks to slide simultaneously. The sliding of the two arc-shaped racks drives the two second housing parts to slide closer to or further away from the first housing part, thereby changing the distance between the far ends of the first and second housing parts, thus changing the angle of the curved display screen. At the same time, through the meshing between the adjusting gears and the arc-shaped racks, the sliding distance of the second housing part relative to the first housing part is predictable, making it easier to accurately adjust the curvature of the curved display screen. This improves the problem that although the curvature of the display screen can be adjusted, the sliding distance of the first and second splicing bodies is difficult to control during the sliding process, making it difficult to accurately adjust the curvature of the display screen.

[0033] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0034] This application discloses an arc adjustment mechanism. (Refer to...) Figure 1 and Figure 2 An arc adjustment mechanism includes a drive rod 1, two sets of adjustment housings 2, two sets of adjustment components 3, and a locking component 4. The two adjustment housings 2 are respectively disposed at both ends of the drive rod 1, the two sets of adjustment components 3 are respectively disposed at the two adjustment housings 2, and the locking component 4 is disposed at one end of the drive rod 1.

[0035] Reference Figure 2 and Figure 3 The drive rod 1 includes a main body 11, a first rod body 12, and a second rod body 13. The main body 11 is cylindrical, and anti-slip textures 111 are engraved on its outer circumference. The first rod body 12 and the second rod body 13 are slidably fitted to both ends of the main body 11. The first rod body 12 has a first rotating groove 121 at one end near the main body 11, and the second rod body 13 has a second rotating groove 131 at one end near the main body 11. The main body 11 has multiple through rotating holes 112, and each rotating hole 112 is threadedly connected to a rotating protrusion 11. 21. Each rotating protrusion 1121 passes through the first rotating groove 121 and the second rotating groove 131 respectively and abuts against the bottom of the first rotating groove 121 and the second rotating groove 131 respectively. As a result, when the drive rod 1 drives each rotating protrusion 1121 to rotate, the first rod body 12 and the second rod body 13 rotate accordingly. The width of the first rotating groove 121 is larger than the diameter of the rotating protrusion 1121. As a result, when the first rod body 12 slides toward or away from the main body 11, it is not easy to drive the main body 11 to slide in the same direction as the first rod body 12.

[0036] Reference Figure 2 and Figure 4Both adjusting housings 2 include a first housing part 21 and a second housing part 22. Both the first housing part 21 and the second housing part 22 are arc-shaped. The two first housing parts 21 are respectively disposed on the side close to the drive rod 1. One first housing part 21 is rotatably connected to the first rod body part 12, and the other first housing part 21 is rotatably connected to the second rod body part 13. The two second housing parts 22 are respectively disposed on the side away from the drive rod 1. The two first housing parts 21 and the two second housing parts 22 are respectively in arc-shaped sliding cooperation.

[0037] Reference Figure 2 and Figure 4 Each of the two first housing parts 21 is fixedly connected to a guide block 211 near one of the two second housing parts 22. Each of the two second housing parts 22 has a guide groove 221 with an arc-shaped groove. The two guide blocks 211 pass through and slide into the two guide grooves 221 respectively. Each of the two guide blocks 211 is fixedly connected to an abutment block by screws. Each of the two guide grooves 221 has an abutment groove. When the two guide blocks 211 pass through and slide into the two guide grooves 221 respectively, the two abutment blocks pass through the two abutment grooves respectively and abut against the two abutment grooves respectively, thereby making the sliding fit between the first housing part 21 and the second housing part 22 more stable.

[0038] Reference Figure 2 and Figure 4 Both sets of adjustment components 3 include arc-shaped racks 31 and adjustment gears 32. The two arc-shaped racks 31 are coaxially fixedly disposed on the two second housing parts 22, and the two adjustment gears 32 are rotatably disposed on the two first housing parts 21. The two adjustment gears 32 mesh with the two arc-shaped racks 31 respectively. One adjustment gear 32 close to the first rod part 12 is coaxially fixed to the first rod part 12, and the other adjustment gear 32 close to the second rod part 13 is coaxially fixed to the second rod part 13. Thus, when the first rod part 12 slides toward or away from the main body part 11, one adjustment gear 32 moves in the same direction as the sliding direction of the first rod part 12.

[0039] Reference Figure 2 and Figure 4 The locking assembly 4 includes two locking blocks 41. Each of the two second housing parts 22 has a locking groove 222 with an arc-shaped groove. The two locking grooves 222 are coaxially arranged with the two second housing parts 22 respectively. The two locking blocks 41 pass through and slide into the two locking grooves 222 respectively. One locking block 41 is rotatably connected to the first rod part 12, and the other locking block 41 is rotatably connected to the second rod part 13. When the first rod part 12 slides towards the main body part 11, one locking block 41 slides towards the locking groove 222 until it is pressed and fixed with the locking groove 222, thereby pressing and fixing the first housing part 21 and the second housing part 22 together, thereby locking the relative sliding of the first housing part 21 and the second housing part 22.

[0040] Reference Figure 5 and Figure 6 A connecting sleeve 212 is fixedly provided on one side of the first housing part 21 near the first rod part 12. A through connecting hole 2121 is provided in the middle of the connecting sleeve 212. The first rod part 12 passes through and rotates to fit into the connecting hole 2121. The locking assembly 4 also includes a driving sleeve 42. The driving sleeve 42 passes through the connecting sleeve 212 and is threadedly connected to the connecting sleeve 212. When the driving sleeve 42 rotates relative to the connecting sleeve 212, the driving sleeve 42 moves toward or away from the adjusting housing 2.

[0041] Reference Figure 4 and Figure 5 The first rod body 12 has a drive groove 122 in the shape of a ring. The drive sleeve 42 is threadedly connected to two drive protrusions 421. The two drive protrusions 421 are arranged opposite each other. The drive protrusions 421 pass through the drive groove 122 and abut against the groove body of the drive groove 122. When the drive sleeve 42 moves relative to the adjusting housing 2, the drive protrusions 421 drive the first rod body 12 to move through the drive groove 122. The outer circumferential surface of the connecting sleeve 212 has two through-hole limiting grooves 2122. The connecting hole 2121 and the two limiting grooves 2122 are connected. The drive groove 122 is connected to the two limiting grooves 2122. The two drive protrusions 421 pass through the two limiting grooves 2122 respectively and slide against the drive groove 122. When the drive sleeve 42 rotates to the set position, the two drive protrusions 421 abut against the groove body of the two limiting grooves 2122 respectively.

[0042] Reference Figure 6 , Figure 7 as well as Figure 8Each of the two first housing parts 21 is slidably fitted with an adjusting ball 213. An adjusting spring 214 is provided between each adjusting ball 213 and each of the two first housing parts 21. One end of each adjusting spring 214 is fixedly connected to the two adjusting balls 213, and the other end of each adjusting spring 214 is fixedly connected to each of the two first housing parts 21. Each of the two second housing parts 22 has multiple adjusting grooves 223 on one side near the two first housing parts 21. These grooves 223 are evenly distributed along the length of the second housing part 22. When the second housing part 22 slides with the first housing part 21, the adjusting ball 213 moves from one adjusting groove 223 to another and engages with that groove 223. Each of the first housing parts 21 is engraved with a scale pointer 215, the position of which is directly opposite the position of the adjustment ball 213. Each of the two second housing parts 22 is engraved with an adjustment scale 224, the value of which corresponds one-to-one with the position of each adjustment slot 223. The value of the adjustment scale 224 pointed to by the scale pointer 215 is the curvature value of the curved screen. Thus, when the second housing part 22 slides relative to the first housing part 21 to adjust the curvature of the display screen, the adjustment ball 213 moves from one adjustment slot 223 to another adjustment slot 223 and engages with the adjustment slot 223, thereby completing the adjustment of the set curvature and further improving the precision of the display screen curvature adjustment.

[0043] The implementation principle of the arc adjustment mechanism in this application embodiment is as follows: When the arc of the curved display screen needs to be adjusted, the drive rod 1 rotates, and the two ends of the drive rod 1 respectively drive the two adjustment gears 32 to rotate simultaneously. When the two adjustment gears 32 rotate simultaneously, they respectively drive the two arc racks 31 to slide simultaneously. The sliding of the two arc racks 31 respectively drives the two second housing parts 22 to slide towards or away from the first housing part 21, thereby changing the distance between the far ends of the first housing part 21 and the second housing part 22, thereby changing the angle of the curved display screen. At the same time, through the meshing between the adjustment gears 32 and the arc racks 31, the sliding distance of the second housing part 22 relative to the first housing part 21 is predictable, thereby making it easier to accurately adjust the arc of the curved display screen. This improves the problem that although the purpose of adjusting the arc of the display screen is achieved, the sliding distance of the first splicing body and the second splicing body is not easy to control during the sliding process, thus making it difficult to accurately adjust the arc of the display screen.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
