Description

Technical Field

[0001] The utility model relates to the technical field of display screen swing devices, in particular to a display screen swing assembly. Background Art

[0002] In recent years, as the automotive industry has continued to transform towards electrification, consumers' demands for car functions have become increasingly diverse. From in-car multimedia screens to the popularity of LCD instruments + smart touch screens, it has not only changed people's travel methods, but also made car life more fulfilling.

[0003] Multimedia display screens are generally installed on the center console of a car. In order to meet the needs of different consumers, many car-mounted display screens are currently designed to swing left and right to enhance the user experience of the main driver and the front passenger. However, in actual use, it is found that when the existing swing device drives the display screen to swing left and right, the left or right side of the display screen will have a large displacement in the front-to-back direction. For example, when the swing device drives the display screen to swing to the left, the left side of the display screen will move forward and approach the center console, and the right side of the display screen will move backward and away from the center console. This means that if the reserved space between the display screen and the center console is small, the display screen will collide with the center console after swinging to a certain angle; and if the reserved space between the display screen and the center console is designed to be larger, it will occupy the space inside the car and affect the passenger experience. Utility Model Content

[0004] The utility model aims to provide a display screen swing assembly which can provide a sufficient swing angle for the display screen and reduce the reserved space required between the display screen and the central console.

[0005] In order to solve the above problems, the utility model provides a display screen swing assembly, including a base shell, a swing frame, a guide rod and a power piece, the base shell is provided with a base plate arranged in a transverse direction, the swing frame is slidably matched with the base plate in a transverse direction, the front side of the swing frame is provided with an assembly area for installing the display screen and the rear side is provided with a raised guide piece, and the front part of the swing frame extends out of the front side of the base plate, the base plate is provided with a guide rail which is an overall V-shaped and the V-shaped opening is arranged forward, the guide piece is slidably matched to the guide rail, the guide rod is slidably connected to the base plate in a front-to-back direction, the front end of the guide rod is connected to the front part of the swing frame by rotating along a vertical rotating shaft, the power piece is installed on the base shell and the output end of the power piece acts on the rear part of the swing frame to drive the rear part of the swing frame to swing left or right, so that the guide piece slides to the left front or right front along the guide rail, and then the front part of the swing frame rotates left and right around the rotating shaft.

[0006] Compared with the prior art, the above scheme, on the one hand, designs the swing frame to be slidably matched to the base plate in the transverse direction, by designing a guide rail that is an overall V-shaped on the base plate, and providing a guide member at the rear of the swing frame, and guiding the swing trajectory of the swing frame through the limiting effect of the guide rail on the sliding trajectory of the guide member; on the other hand, by providing a guide rod that can slide in the front and rear directions on the base plate, and the front end of the guide rod is rotatably connected to the front part of the swing frame through a rotating shaft, so that when the power member drives the rear part of the swing frame to make the guide member in the V-shaped tip position of the guide rail, the limit pin and the swing frame will be in a rearward position, and the guide rod The swing frame is also driven in a rear position, the space between the display screen and the base shell is small, and the structure is compact; when the power part drives the rear part of the swing frame to swing left or right, the guide part will slide along the guide rail to the left front or right front, and the front part of the swing frame will rotate left and right around the axis of rotation at this time, so as to realize the left and right swing function of the display screen. At the same time, because the limit pin and the swing frame are in a forward position at this time, the guide rod is also driven by the swing frame to a forward position, so the space between the display screen and the base shell is increased, so as to avoid the collision between the display screen and the base shell during the left and right swinging process, and ensure that the display screen has a larger swing angle.

[0007] In an improved solution, the swing frame is located on the lower side of the base plate, the guide rod is located on the upper side of the base plate, the guide rail is a slide groove, the guide member is a guide pin, and the guide pin is slidably inserted into the slide groove. The guide rail of the slide groove structure and the guide member of the guide pin structure have simple structures and are easy to process and assemble. The guide pin can slide stably along the slide groove and has good structural reliability.

[0008] In an improved scheme, the base shell is provided with a vertical tightening spring, the groove width of the slide groove gradually increases from top to bottom, the outer diameter of the part of the guide pin that is slidably inserted in the slide groove gradually increases from top to bottom, and an assembly gap is left between the lower end surface of the substrate and the base shell, the tightening spring acts on the substrate and applies a downward thrust to the substrate, so that the groove wall of the slide groove and the outer peripheral wall of the guide pin are always in close contact, so that when the contact part between the guide pin and the slide groove is worn, the tightening spring will provide downward pressure to the substrate, because the groove width of the slide groove gradually increases from top to bottom, and the outer diameter of the part of the guide pin that is slidably inserted in the slide groove gradually increases from top to bottom, after the substrate is pressed downward by the tightening spring, the outer peripheral wall of the guide pin and the groove wall of the slide groove will always maintain a relatively close contact state, effectively avoiding the loosening problem between the guide pin and the slide groove caused by wear.

[0009] In an improved scheme, the slide groove vertically penetrates the base plate, the upper end of the guide pin protrudes from the upper end surface of the base plate, the groove width at the V-shaped tip position of the slide groove is larger than the outer diameter of the guide pin, and a limit block that can slide in the front-to-back direction is provided on the base plate in front of the V-shaped tip of the slide groove, the rear part of the limit block is provided with a limit end and the width of the limit end gradually decreases from front to back, and the base plate is provided with a limit spring acting on the limit block, and the limit spring is used to apply a backward thrust to the limit block, so that when the guide pin is at the V-shaped tip position of the slide groove, the limit end abuts against the guide pin and pushes the guide pin toward the groove wall on the rear side of the slide groove, thereby making the swing trajectory of the front part of the swing frame smoother, ensuring that the actual swing trajectory of the display screen can better meet the design requirements.

[0010] The cam is an axially parallel track of the rear wheel, and the cam is adapted to move the cam forward and backward to move the wheel backwards, thereby preventing the cam from moving backwards or forwards, thereby preventing the cam from moving backwards or forwards.

A limit pin is provided at the output end of the power member, and a guide groove along the front and rear directions is provided at the lower side of the swing frame. The limit pin slides into the guide groove, so that when the power member drives the limit pin to move linearly to the left or right, the limit pin will slide relative to the guide groove, so that the rear part of the swing frame is pushed by the limit pin and swings to the left or backward.

[0012] In an improved solution, the power part includes a motor, a screw and a nut stand. The screw is connected to the base shell and rotates with the left and right directions as the axis. The motor is installed in the base shell and drives the screw to rotate. The nut stand is threaded to the screw and driven by the screw to move left and right. The limit pin is connected to the nut stand to ensure more precise driving of the limit pin.

[0013] In an improved solution, the nut platform is provided with a screw sleeve, and the nut platform is screwed to the screw rod through the screw sleeve. The side circumferential wall of the screw sleeve is provided with a plurality of circumferentially distributed through grooves, and the outer circumferential side of the screw sleeve is sleeved with an annular elastic member, and the elastic member is used to tighten the screw sleeve toward the screw rod, so that by providing a plurality of circumferentially distributed through grooves on the side circumferential wall of the screw sleeve, the screw sleeve has a certain radial deformation ability, and then by sleeved with the elastic member on the outer circumferential side of the screw sleeve, when the threaded surface of the screw sleeve or the screw rod is worn, the elastic member tightens the screw sleeve toward the screw rod, ensuring that the screw sleeve and the screw rod are always in a tight threaded fit, effectively improving stability.

[0014] In an improved solution, a vertical insertion hole is provided at the front end of the guide rod, an annular convex step is provided at the upper part of the insertion hole, a transfer hole is provided at the front part of the swing frame in the vertical direction, the upper end of the rotating shaft is slidably inserted into the insertion hole and the lower end is rotatably inserted into the transfer hole, a screw hole is provided in the vertical direction on the end surface of the upper end of the rotating shaft, a gap adjustment spring is provided between the upper end of the rotating shaft and the annular convex step, a bolt is provided on the annular convex step, a nut end of the bolt abuts against the upper side of the annular convex step and a screw end passes through the annular convex step and is connected to the screw hole. Since the guide rod is long and the guide rod It is connected to the upper side of the base plate by sliding along the front-to-back direction. Therefore, there is a certain assembly error in the vertical direction at the front end of the guide rod when it moves. Therefore, a socket is set at the front end of the guide rod, and the upper end of the rotating shaft is slidably inserted into the socket to ensure that the front end of the guide rod and the rotating shaft can be effectively assembled.

[0030] The present application is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] See also Figure 1-Figure 9 The embodiment of the utility model provides a display screen swing assembly, including a base shell 1, a swing frame 3, a guide rod 4 and a power piece 6. The base shell 1 is provided with a substrate 2 arranged in a transverse direction, and the swing frame 3 is slidably matched with the lower side of the substrate 2 in a transverse direction. The front side of the swing frame 3 is provided with an assembly area 31 for installing a display screen and the rear side is provided with an upwardly protruding guide piece 32, and the front part of the swing frame 3 extends out of the front side of the substrate 2, and the lower end surface of the substrate 2 is provided with a guide rail 21 which is V-shaped as a whole and the V-shaped opening is arranged forward, and the guide piece 32 is slidably matched to the guide rail 21, and the guide rod 4 is slidably connected to the upper side of the substrate 2 in the front-to-back direction, and the front end of the guide rod 4 is rotatably connected to the front part of the swing frame 3 by a vertical rotating shaft 5, and the power piece 6 is installed on the base shell 1 and the output end of the power piece 6 acts on the rear part of the swing frame 3 to drive the rear part of the swing frame 3 to swing left or right, so that the guide piece 32 slides to the left front or right front along the guide rail 21, and then the front part of the swing frame 3 rotates left and right around the rotating shaft 5.

[0032] Compared with the prior art, the above scheme, on the one hand, designs the swing frame 3 to be slidably fitted to the base plate 2 in the transverse direction, by designing a guide rail 21 that is overall V-shaped on the base plate 2, and providing a guide member 32 at the rear of the swing frame 3, and the swing trajectory of the swing frame 3 is guided by the limiting effect of the guide rail 21 on the sliding trajectory of the guide member 32; on the other hand, a guide rod 4 that can slide in the front and rear directions is provided on the base plate 2, and the front end of the guide rod 4 is rotatably connected to the front part of the swing frame 3 through the rotating shaft 5, so that when the power member 6 drives the rear part of the swing frame 3 to make the guide member 32 in the V-shaped tip position of the guide rail 21, the limit pin 64 and the swing frame 3 will be in the rear position, and this When the guide rod 4 is driven by the swing frame 3 to be in a rearward position, the space between the display screen and the base shell 1 is small and the structure is compact; when the power member 6 drives the rear part of the swing frame 3 to swing left or right, the guide member 32 will slide along the guide rail 21 to the left front or right front, and the front part of the swing frame 3 will rotate left and right around the rotating shaft 5 at this time, so as to realize the left and right swinging function of the display screen. At the same time, since the limit pin 64 and the swing frame 3 are in a forward position at this time, the guide rod 4 is also driven by the swing frame 3 to be in a forward position, so the space between the display screen and the base shell 1 is increased, so as to avoid the collision between the display screen and the base shell 1 during the left and right swinging process, and ensure that the display screen has a larger swinging angle.

[0033] It should be noted that the "overall V-shaped guide rail 21" referred to in this embodiment means that the overall shape of the guide rail 21 in the horizontal direction is V-shaped, and the V-shape here includes conventional variants that are roughly similar in shape to the V-shape, such as a U-shape, etc.; in addition, the guide rail 21 can be a left-right symmetrical V-shape, in which case the swing angles of the swing frame 3 to the left or right are equal; or the guide rail 21 can also be a left-right asymmetrical V-shape, in which case the swing angles of the swing frame 3 to the left or right are not equal, which can be adjusted according to actual needs, and the present design does not limit this.

[0034] It should be noted that the "guide rod 4 is connected to the upper side of the base plate 2 in a sliding manner along the front-to-back direction" referred to in this embodiment means roughly along the front-to-back direction, that is, the sliding direction of the guide rod 4 is allowed to be deflected to a certain extent. When the sliding direction of the guide rod 4 is a strict front-to-back direction, the swing angles of the swing frame 3 to the left or right are equal; when the sliding direction of the guide rod 4 is a deflected front-to-back direction, the swing angles of the swing frame 3 to the left or right are not equal; in addition, when the position of the guide rod 4 relative to the base plate 2 is exactly in the middle of the left-to-right direction of the guide rail 21, the swing angles of the swing frame 3 to the left or right are equal; when the position of the guide rod 4 relative to the base plate 2 is offset to the middle of the left-to-right direction of the guide rail 21, the swing angles of the swing frame 3 to the left or right are not equal, that is, the specific sliding direction of the guide rod 4 and the position of the guide rod 4 relative to the base plate 2 can be adjusted as needed, and this design does not limit them.

[0035] Since the swing frame 3 in this embodiment is designed to have equal left and right swing angles, the guide rail 21 is a left-right symmetrical V-shape, and the guide rod 4 is slidably connected to the upper side of the base plate 2 along a strict front-to-back direction, and the position of the guide rod 4 relative to the base plate 2 is exactly in the middle of the left-right direction of the guide rail 21.

[0036] In this embodiment, the base shell 1 is roughly box-shaped, the base plate 2 is connected to the middle position of the base shell 1 in the vertical direction, the swing frame 3 is preferably in the shape of a flat plate, and the upper side of the swing frame 3 is slidably fitted with the lower end surface of the base plate 2, so as to achieve the effect of "the swing frame 3 slides along the horizontal direction to fit the lower side of the base plate 2"; of course, the "swing frame 3 slides along the horizontal direction to fit the lower side of the base plate 2" mentioned here is just a Figure 1 For reference, the swing frame 3 can also be slidably fitted to the upper side of the base plate 2 in the transverse direction as needed, and other related structures can be adaptively turned upside down, which should not be regarded as an actual limitation.

[0037] The guide rail 21 can be a sliding guide structure in the prior art, such as a slide rail structure, as long as it can guide the sliding track of the guide member 32 to be V-shaped in the plane direction. In this embodiment, the guide rail 21 is a slide groove, and the guide member 32 is a guide pin, which is slidably inserted into the slide groove. The guide rail 21 with the slide groove structure and the guide member 32 with the guide pin structure have a simple structure, are easy to process and assemble, and the guide pin can stably slide along the slide groove, and the structural reliability is good.

[0038] As an improvement to this embodiment, the width of the slide groove gradually increases from top to bottom so that the groove walls on both sides of the slide groove are inclined; the outer diameter of the part of the guide pin that is slidably inserted in the slide groove gradually increases from top to bottom, and the slope of the outer peripheral wall of the guide pin is roughly equal to the slope of the groove wall of the slide groove. An assembly gap is left between the lower end surface of the base plate 2 and the base shell 1. A vertical tightening spring 11 is provided on the upper part of the base shell 1. The lower end of the tightening spring 11 abuts against the upper side surface of the base plate 2, thereby applying a downward thrust to the base plate 2, so that the groove wall of the slide groove and the outer peripheral wall of the guide pin are always in close contact. When the contact portion between the guide pin and the slide groove is worn, the tightening spring 11 will provide downward pressure to the base plate 2. Since the groove width of the slide groove gradually increases from top to bottom, and the outer diameter of the part of the guide pin that is slidably inserted in the slide groove gradually increases from top to bottom, after the base plate 2 is pressed downward by the tightening spring 11, the outer peripheral wall of the guide pin and the groove wall of the slide groove will always maintain a relatively close abutment state, effectively avoiding the loosening problem between the guide pin and the slide groove caused by wear.

[0039] As another improvement to this embodiment, the slide groove vertically penetrates the substrate 2, the upper end of the guide pin protrudes from the upper end surface of the substrate 2, the groove width at the V-shaped tip position of the slide groove is greater than the outer diameter of the guide pin, and a limit block 22 that can slide in the front and rear directions is provided on the substrate 2 at a position in front of the V-shaped tip of the slide groove, and a limit end 221 is provided at the rear of the limit block 22 and the width of the limit end 221 gradually decreases from front to rear, and the substrate 2 is provided with a limit spring 23 acting on the limit block 22, the front end of the limit spring 23 abuts against the boss on the upper side of the substrate 2, and the rear end of the limit spring 23 abuts against the limit block 22 to apply a backward thrust to the limit block 22, so that when the guide pin is at the V-shaped tip position of the slide groove, the limit end 221 abuts against the guide pin and pushes the guide pin to the groove wall on the rear side of the slide groove, thereby making the swing trajectory of the front part of the swing frame 3 smoother, ensuring that the actual swing trajectory of the display screen can better meet the design requirements.

[0040] See also Figure 7-Figure 9 In this embodiment, the power member 6 is located below the swing frame 3. The power member 6 is a linear driving member arranged along the left and right directions. A limit pin 64 is provided at the output end of the power member 6. A guide groove 33 along the front and rear directions is provided at the lower side of the swing frame 3. The limit pin 64 slides into the guide groove 33. When the power member 6 drives the limit pin 64 to move linearly to the left or right, the limit pin 64 will slide relative to the guide groove 33, so that the rear part of the swing frame 3 is pushed by the limit pin 64 and swings to the left or backward.

[0041] As an improvement to the present embodiment, the power member 6 is located below the swing frame 3. The power member 6 is a linear driving member arranged along the left-right direction. A limit pin 64 is arranged at the output end of the power member 6. A guide groove 33 along the front-back direction is arranged at the lower side of the rear portion of the swing frame 3. The groove width of the guide groove 33 gradually increases from top to bottom. The outer diameter of the upper end of the limit pin 64 gradually increases from top to bottom. The upper end of the limit pin 64 is slidably inserted into the guide groove 33. Therefore, when the power member 6 drives the limit pin 64 to move linearly to the left or right, the limit pin 64 will slide relative to the guide groove 33. The rear part of the swing frame 3 is pushed by the limit pin 64 to swing to the left or backward. At the same time, since the width of the guide groove 33 gradually increases from top to bottom, and the outer diameter of the upper end of the limit pin 64 gradually increases from top to bottom, when the tightening spring 11 provides downward pressure to the substrate 2, the swing frame 3 is also subjected to the downward pressure of the substrate 2. Therefore, after the swing frame 3 is pressed downward by the substrate 2, the outer peripheral wall of the limit pin 64 and the groove wall of the guide groove 33 will always maintain a relatively close abutment state, effectively avoiding the loosening problem between the limit pin 64 and the guide groove 33 caused by wear.

[0042] The power part 6 preferably includes a motor 61, a screw rod 62 and a nut base 63. The screw rod 62 is connected to the base shell 1 and rotates with the left and right directions as the axis. The motor 61 is installed in the base shell 1 and drives the screw rod 62 to rotate. The nut base 63 is screwed to the screw rod 62 and is driven by the screw rod 62 to move left and right. The limit pin 64 is connected to the nut base 63, thereby ensuring that the drive of the limit pin 64 is more precise.

[0043] like Fig. 9 As shown, further, the nut platform 63 is provided with a threaded sleeve 631, and the nut platform 63 is screwed to the screw rod 62 through the threaded sleeve 631. The side circumferential wall of the threaded sleeve 631 is provided with a plurality of circumferentially distributed through grooves 633, and the outer circumferential side of the threaded sleeve 631 is sleeved with an annular elastic member 632, and the elastic member 632 is preferably a rubber ring. The elastic member 632 is used to tighten the threaded sleeve 631 toward the screw rod 62, so that by providing a plurality of circumferentially distributed through grooves 633 on the side circumferential wall of the threaded sleeve 631, the threaded sleeve 631 has a certain radial deformation ability, and then by sleeved with the elastic member 632 on the outer circumferential side of the threaded sleeve 631, when the threaded surface of the threaded sleeve 631 or the screw rod 62 is worn, the elastic member 632 tightens the threaded sleeve 631 toward the screw rod 62, ensuring that the threaded sleeve 631 and the screw rod 62 are always in a tight threaded fit, thereby effectively improving the stability.

[0044] Of course, the power member 6 can also be other forms of linear drive members such as racks, cylinders, electric cylinders, etc. arranged along the left and right directions, as long as it can drive the rear part of the swing frame 3 to swing left or right. This design does not limit this.

[0045] As an improvement to the present embodiment, a vertical insertion hole 41 is provided at the front end of the guide rod 4, an annular convex step 42 is provided at the upper part of the insertion hole 41, a transfer hole 34 is provided at the front part of the swing frame 3, the upper end of the rotating shaft 5 is slidably plugged into the insertion hole 41 and the lower end is rotatably plugged into the transfer hole 34, a screw hole 51 is provided vertically on the end surface of the upper end of the rotating shaft 5, a gap adjustment spring 53 is provided between the upper end of the rotating shaft 5 and the annular convex step 42, a bolt 52 is provided at the annular convex step 42, a nut end of the bolt 52 abuts against the upper side of the annular convex step 42 and the screw end passes through the annular convex step 42 and is connected to the screw hole 51, since the guide rod 4 is long and the guide rod 4 is slidably connected in the front-rear direction It is connected to the upper side of the base plate 2, so the front end of the guide rod 4 has a certain assembly error in the vertical direction when moving. Therefore, a socket 41 is set at the front end of the guide rod 4, and the upper end of the rotating shaft 5 is slidably inserted into the socket 41 to ensure that the front end of the guide rod 4 and the rotating shaft 5 can be effectively assembled, and then the screw end of the bolt 52 is passed through the annular convex step 42 and connected to the screw hole 51 of the rotating shaft 5 to prevent the rotating shaft 5 from escaping from the socket 41; and the gap adjustment spring 53 located between the upper end of the rotating shaft 5 and the annular convex step 42 can push the rotating shaft 5 downward, so that the rotating shaft 5 is tightened relative to the socket 41, avoiding the loosening problem caused by the rotating shaft 5 sliding freely relative to the socket 41.

[0046] As an improvement to this embodiment, a damping ring 54 is provided between the lower end of the rotating shaft 5 and the swing frame 3, so that the swing frame 3 is more stable when rotating around the rotating shaft 5, and the accidental shaking of the swing frame 3 is reduced.
