Description

Copilot screen amplification device

Technical Field

The invention relates to a mechanical device, in particular to a magnifying device suitable for a vehicle screen.

Background

In recent years, with the increase of the demands of the market and users on the comfort of vehicles, some automobile manufacturers often mount a screen on the passenger side of the dashboard for the passenger in the passenger side and the passenger in the second row during the production of new vehicles, and the screen is generally used for watching videos under normal conditions.

Considering the safety performance of the vehicle, the interference of the auxiliary driving screen with the air bag blasting is avoided, the opening of the auxiliary driving air bag is not limited, and when the auxiliary driving screen is installed and designed, the screen is generally required to be not higher than an instrument panel. Meanwhile, the copilot screen cannot be too low in consideration of the size and modeling problem of the glove box of the vehicle and the comfort level of watching videos by a man-machine. It follows that the above two factors limit the height size of the co-pilot screen.

In the prior art, a video played by a copilot screen has a certain aspect ratio, and the height and the size of the copilot screen are limited, so that the video area is usually small, and the requirement of passengers cannot be met generally. For example: the copilot screen was set at 281 x 86mm, size 11.6 inches, ratio 29: 9, but since the playing video ratio is 16: 9, the playing area of the video in the screen is only 6.9 inches, the playing area is not larger than that of the mobile phone, and the playing effect is not ideal.

Further, it is found from human-computer analysis that, in the cabin of the automobile, the eyes of the passengers on the passenger seat are generally about 90cm away from the screen, and the eyes of the passengers in the second row are generally about 320cm away from the screen. If the distance between the human eyes and the screen is 90cm, the requirement of the video area in the screen is better to be more than 12.3 inches from the analysis of the comfort angle, and if the video playing video area in the screen is only 6.9 inches, the passengers are not comfortable to watch the video. The video playing video area of 6.9 inches appears smaller in consideration of the distance between the human eyes of the second passenger and the screen.

Based on this, the invention is expected to obtain a copilot screen amplifying device, which can be effectively applied to a vehicle and used as a vehicle accessory to assist passengers to watch videos in a screen, can conveniently and effectively amplify the screen and improve the video watching experience of users, and has excellent practicability and economy, good popularization prospect and application value.

Detailed Description

The co-driver screen enlarging apparatus according to the present invention will be further explained and illustrated with reference to the drawings and the specific embodiments of the present specification, however, the explanation and the illustration do not unduly limit the technical solution of the present invention.

As shown in fig. 1, in the present embodiment, the passenger screen enlarging apparatus according to the present invention may include: the rotary bracket 1, the fixed bracket 2 and the magnifying glass telescopic rotary bracket 3. Wherein, a cavity 11 is arranged in the rotary bracket 1; the fixed bracket 2 is fixedly arranged on the upper surface of the rotating bracket 1; the magnifying glass telescopic rotary bracket 3 is contracted in the cavity 11 of the rotary bracket 1 in a contraction state.

Accordingly, in the present embodiment, the fixing bracket 2 in the copilot screen magnification device according to the present invention may include: a fixed bracket assembly 21 and a screen assembly telescopic bracket 22. The screen assembly telescopic bracket 22 can be used for clamping and fixing the screen assembly 4, and can telescopically control the screen assembly 4 to move along the width direction (X direction) of the rotating bracket so as to adjust the distance between the screen assembly 4 and the rotating bracket 1.

It should be noted that, in the present invention, the screen assembly telescopic bracket 22 can be driven by electric power or manual power. In this embodiment, the invention uses an electric screen assembly telescopic bracket, and in some other embodiments, the device can also use a manual screen assembly telescopic bracket.

In this embodiment, the screen assembly 4 may be a mobile phone, and the screen assembly extension bracket 22 may extend and hold the mobile phone, as shown in fig. 2. Of course, when the user does not use the copilot screen amplifying device, the user can detach the mobile phone.

In the present invention, the fixing bracket assembly 21 of the fixing bracket 2 and the electric screen assembly stretching bracket 22 are constructed as shown in fig. 3 and 4.

As shown in fig. 3 and 4, in the present embodiment, the fixing bracket assembly 21 may include: a fixed bracket body 211 (see fig. 50) and a rotary screw 212 (see fig. 50). In this embodiment, the electric screen assembly telescopic bracket 22 may include: a screen assembly retracting mechanism 221, a screen assembly holding mechanism 222, and a rotating motor 223.

In this embodiment, specific structures of the fixing bracket main body, the rotary screw, the screen assembly stretching mechanism, and the screen assembly holding mechanism may be as shown in fig. 5 to 7 described below.

Fig. 5 is a schematic structural view of a screen assembly retracting mechanism of a copilot screen magnifying device according to an embodiment of the present invention. Fig. 6 is a schematic structural view of a screen assembly holding mechanism of a copilot screen magnifying device according to an embodiment of the present invention. Fig. 7 is a schematic structural view of a rotary motor in an embodiment of the copilot screen magnifying device according to the present invention.

As shown in fig. 8 and 9, in the present embodiment, the process of extending the electric screen unit extension bracket 22 with respect to the rotation bracket 1 in the copilot screen magnifying device according to the present invention can be seen with reference to fig. 8 and 9.

As shown in fig. 8, in the initial state, the electric screen assembly telescopic bracket 22 is in an un-telescopic state relative to the rotating bracket 1, which can be limited by the rotating motor 223, and there is no manual version of the initial state locking mechanism, the extended state locking spring, the damping, and the ejection spring part.

Accordingly, as shown in fig. 9, the screen assembly telescopic bracket 22 can be extended relative to the rotating bracket 1 by the rotating motor 223, which is also limited by the rotating motor 223. The screen assembly holding mechanism 222 can be used to hold the phone when the screen assembly extension bracket 22 is extended.

Of course, in some other embodiments, the present invention may also adopt a manual screen assembly telescopic bracket, which is different from an electric screen assembly telescopic bracket driven by a rotating motor, and the manual screen assembly telescopic bracket does not need the rotating motor 223, and includes an initial state locking mechanism 224, an extended state locking elastic sheet 225, a damper 227 and an ejection spring 226 in addition to the screen assembly telescopic mechanism 221 and the screen assembly clamping mechanism 222, as shown in fig. 10.

As shown in fig. 10, the screen assembly retracting mechanism 221 and the screen assembly holding mechanism 222 in the manual screen assembly retracting bracket 22 may be the same as those shown in fig. 5 and 6. Accordingly, the initial state locking mechanism 224 and the extended state locking spring 225 may be as shown in fig. 11 and 12 described below.

Fig. 11 schematically shows a structural view of an initial state locking mechanism in a manual screen assembly telescopic bracket. Fig. 12 schematically shows a structure of an extended state locking spring in a telescopic bracket of a manual screen assembly.

To explain the process of extending the manual screen assembly telescopic bracket with respect to the rotary bracket 1 in the manual extension by the user, it can be assumed that the manual screen assembly telescopic bracket is used in the passenger screen enlarging apparatus shown in fig. 1 and 2, and thus fig. 13 and 14 described below can be obtained.

As shown in fig. 13, in the initial state, the manual screen assembly telescopic bracket 22 is in an un-telescopic state relative to the rotating bracket 1, and it can be locked by the initial state locking mechanism 224.

Accordingly, as shown in fig. 14, the user can manually press the manual screen assembly telescopic bracket 22 to unlock the initial state locking mechanism 224, and after the initial state locking mechanism 224 is unlocked, the manual screen assembly telescopic bracket 22 can smoothly move to a state where the ejection spring 226 has no acting force under the action of the ejection spring 226 and the damper 227.

It should be noted that, in the state where the ejecting spring 226 has no acting force, the user can manually press the recessed portion on the screen assembly stretching mechanism 221, that is, the screen assembly clamping mechanism 222 can be easily pulled to the extended handset clamping state, and the size is limited by the extended state locking elastic piece 225.

As shown in fig. 15, when the manual screen assembly telescopic bracket 22 is in the fully extended state, the extended state locking elastic piece 225 may be adopted to lock, and at this time, the extended state locking elastic piece 225 may be matched with a concave portion on the screen assembly telescopic mechanism 221 and embedded therein, and may be unlocked only by a certain external force. When the locking spring 225 needs to return, unlocking of the extended state locking spring can be achieved only by applying certain external force.

In the copilot screen amplifying device, the magnifying lens telescopic rotating bracket 3 can be driven by electric power or manual power. The telescopic rotary bracket of the electric magnifier is driven in an electric mode; the telescopic rotary bracket of the manual magnifier is driven in a manual mode.

As shown in fig. 16 and 17, in the present embodiment, the magnifying glass telescopic rotary stand 3 according to the present invention may include: a magnifier lens 301, a lens holder 302, a lens holder mount 303, a telescoping assembly, and a rotational locking mechanism. Wherein, the magnifying lens 301 is fixedly arranged in the lens fixing frame 302; the lens holder support 303 is rotatably connected to the lens holder 302, and the lens holder 302 is disposed on the lens holder support 303 and can rotate in a first rotational direction around a rotational axis therebetween.

Correspondingly, the telescopic assembly arranged in the lens fixing frame support can telescopically adjust the lens fixing frame support 303 to extend out relative to the rotating bracket 1; the rotation lock mechanism can lock the rotation of the lens holder 302 with respect to the lens holder support 303.

In the present embodiment, the retractable rotary stand of the electric magnifier is used in the front-view screen magnifying device according to the present invention, and the structure of the retractable rotary stand can be disassembled into a separate structure shown in fig. 18.

As shown in fig. 18, in the present embodiment, the telescopic assembly and the rotation lock mechanism are provided in the lens fixing frame mount 303. Wherein, the rotation locking mechanism may include: a rotating shaft 309, a roll-over damper 310, a roll-over spring 311, a lens holder roll-over locking lever 307, and a locking lever unlocking spring piece 308.

In the present invention, the lens holder 302 and the lens holder support 303 are rotatably connected by a rotation shaft 309, and the lens holder 302 provided on the lens holder support 303 is rotatable relative to the lens holder support 303 by the rotation shaft 309.

Correspondingly, when the lens fixing frame rotates in a first rotating direction compared with the lens fixing frame support and the rotating locking mechanism is positioned at a locking station, the rotating locking mechanism can prevent the lens fixing frame from rotating in a second rotating direction opposite to the first rotating direction, and the surfaces of the enlarged lenses in the lens fixing frame and the screen in the screen assembly are parallel to each other.

In the telescopic rotary bracket for the magnifier, the lens fixing frame 302 arranged on the lens fixing frame support 303 can be unlocked manually. As shown in fig. 19 and 20, in the present invention, the magnifying lens telescopic rotary frame is provided with unlocking push pieces 315 at both side edges thereof, and the lens holder overturning locking bar 307 is locked when the unlocking push pieces 315 are not pushed.

When the user pushes the unlocking pusher 315 forward in the X direction, the lens holder overturning locking lever 307 is unlocked, as shown in fig. 21 and 22. Figure 21 schematically shows a C-C cross-sectional view of the magnifying glass telescoping rotary stand of figure 16 when a user pushes the unlocking push. FIG. 22 schematically illustrates a D-D cross-sectional view of the magnifying glass telescoping rotational support of FIG. 17 when a user pushes the unlocking push.

As shown in fig. 23 and 24, with reference to fig. 16, in the present invention, the lens fixing frame 302 and the lens fixing frame support 303 in the magnifying glass telescopic rotating bracket 3 are formed by a rotating shaft 309, a turning damper 310 and a turning spring 311. When the user does not push the unlocking push piece 315 and the lens fixing frame overturn locking rod 307 is locked, the overturn spring 311 and the overturn damper 310 in the telescopic rotary bracket of the magnifier are both fixed and do not rotate.

When the user pushes the unlocking push member 315 forward in the X direction, the lens holder inversion locking rod 307 is unlocked, and after the external force applied by the user disappears, the lens holder inversion locking rod 307 can return to the initial position under the action of the return spring. At this time, under the action of the flip spring 311 and the flip damper 310, the magnifier lens 301 and the lens holder 302 rotate around the rotation axis 309 relative to the lens holder mount 303, and when the magnifier lens rotates 90 °, the lens holder 302 and the lens holder mount 303 are positioned in contact.

As shown in fig. 25 and fig. 26, in the telescopic rotary stand 3 of the electric magnifier according to the present invention, the electric telescopic assembly can be pulled by the motor 312 to push the lens fixing frame support 303 to displace in the horizontal X direction.

The electric telescopic assembly may include: a motor 312, a motor rotation lever 313, a first link 304, a second link 317, a third link 314, a fourth link 318, and a support plate 306. The first connecting rod 304 and the second connecting rod 317 have the same structure and are connected with the main rod; the third link 314 and the fourth link 318 are identical in structure and are both tie rods.

As further shown in fig. 25, in the electric telescopic assembly according to the present invention, the motor rotating rod 313 is fixedly connected to the output shaft of the motor 312, and both ends of the motor rotating rod 313 are hinged to the third connecting rod 314 and the fourth connecting rod 318 respectively.

The first sliding chute 3031 and the second sliding chute 3032 may be parallel to each other in the Y direction, and have a certain distance in the vertical Z direction, so as to ensure that the first connecting rod 304 and the second connecting rod 317 in the electric telescopic assembly do not interfere with each other in the moving process, and realize that the first connecting rod 304 and the second connecting rod 317 move in different vertical Z directions.

In addition, it should be noted that the telescopic rotary stand of the electric magnifier according to the present invention may further include a support insert 319 and a support clamping mechanism 320 for supporting, as shown in fig. 28-30.

As shown in fig. 28, 29 and 30, in the present invention, in order to ensure the stability of the electric telescopic assembly in the vertical Z direction, a supporting insert 319 and a supporting clamping mechanism 320 may be further designed. Wherein, the supporting insertion piece 319 can be disposed in the first connecting rod 304, and the supporting clamping mechanism 320 can be disposed on the rotating bracket 1.

As shown in fig. 29, when the electric telescopic assembly is in the fully extended state, the supporting insert 319 can be inserted into the supporting and clamping mechanism 320 of the rotating bracket 1 correspondingly, and the supporting insert 319 and the supporting and clamping mechanism 320 can be matched with each other, thereby functioning to clamp the supporting link.

In addition, in the present invention, in order to ensure the stability of the electric telescopic assembly in the extended state and the stability in the telescopic process, in some embodiments, a first sub-lever 321 and a second sub-lever 322 may be added on the basis of the first link, the second link, the third link, and the fourth link, as shown in fig. 31 and 32 described below.

As shown in fig. 31 and 32, the first sub-rod 321 and the second sub-rod 322 may have their head ends rotatably connected to the first link 304 and the second link 317, respectively, the tail ends of the first sub-rod 321 and the second sub-rod 322 are hinged to the support plate 306, respectively, and the support plate 306 can slide on the first sliding slot 3031 and the second sliding slot 3032, respectively. The first auxiliary rod 321 and the support plate 306 hinged to the end of the first link 304 move on the same slide slot, and the second auxiliary rod 322 and the support plate 306 hinged to the end of the second link 317 also move on the same slide slot.

In summary, in order to further explain the copilot screen magnifying device of the present invention, when the electric magnifying glass is used to extend and retract the rotating bracket, the specific process of adjusting the distance between the magnifying glass and the screen through the electric extending and retracting assembly is adopted in the present invention as described in the following specific embodiment of fig. 33-39.

In the copilot screen magnifying device, the electric telescopic assembly in the magnifying glass telescopic rotating bracket can comprise three states of a contracted state, an intermediate state and a fully extended state.

As shown in fig. 33 and 34, in the initial contracted state, the first link 304, the second link 317, the third link 314, the fourth link 318, the telescopic link mechanism including the lens fixing frame mount 303, and the lens fixing frame 302 are locked by the motor 312.

As shown in fig. 35 and fig. 36, in the present embodiment, the motor 312 in the electric telescopic assembly can drive the motor rotating shaft 313 to rotate, and pull the third link 314 and the fourth link 318, so as to rotate the first link 304 and the second link 317 around the fixed rotating point 316. Meanwhile, the first auxiliary rod 321 and the second auxiliary rod 322 can rotate along with the first auxiliary rod, so as to push the lens fixing frame support 303 to extend until the electric telescopic assembly reaches a fully extended state.

A cross-sectional view of the structure of the passenger screen enlarging apparatus according to the present embodiment when the electric telescopic unit is in the fully extended state is shown in fig. 37.

As shown in fig. 37, 38 and 39, in the present embodiment, after the lens fixing frame support 303 of the copilot screen magnifying device according to the present invention completely extends from the cavity 11 of the rotating bracket 1, the user can manually unlock the lens fixing frame 302 on the lens fixing frame support 303, so that the lens fixing frame 302 and the magnifying lens 301 disposed on the lens fixing frame 302 rotate 90 ° with respect to the lens fixing frame support 303, and at this time, the magnifying lens 301 can effectively magnify the screen of the mobile phone, and the user can watch the screen of the mobile phone 4 through the magnifying lens 301.

Of course, in the copilot screen amplifying device, not only the electric magnifier telescopic rotating bracket but also the manual magnifier telescopic rotating bracket can be adopted. It should be noted that the manual magnifier telescopic rotating bracket eliminates the motor 312, the motor rotating rod 313 and the pull rod (i.e. the third connecting rod and the fourth connecting rod) relative to the electric magnifier telescopic rotating bracket, and adds the ejecting spring 323, the damper 324, the initial state locking mechanism 325, the locking concave wheel 326 and the locking elastic sheet 327.

As shown in fig. 40 and 41, in this embodiment, the passenger screen enlarging apparatus according to the present invention employs a manual telescopic assembly.

Accordingly, the manual retraction assembly employed in the present invention may include: a first link 304, a second link 317, an ejection assembly, and a telescoping locking assembly. The ends of the first link 304 and the second link 317 are respectively hinged to a support plate 306, and the support plate 306 can respectively slide on a first sliding groove 3031 and a second sliding groove 3032 in the fixed frame support 303 of the lens.

In the present embodiment, the ejection assembly includes an ejection spring 323 and a damper 324, and the telescopic locking assembly includes an initial state locking mechanism 325, a locking concave wheel 326, and a locking elastic piece 327. Wherein, the initial state locking mechanism 325 can lock and fix the position of the lens fixing frame support 303 in the contracted state; after a user manually unlocks the initial state locking mechanism 325, the lens fixing frame support 303 can be ejected out under the action of an ejection spring 323 and a damper 324 in the ejection assembly; when the user manually pulls the lens holder support 303 to the fully extended state, the locking concave wheel 326 and the locking elastic piece 327 are capable of mutually cooperating to lock the position of the lens holder support 303.

In the present embodiment, in order to ensure the stability of the manual retraction assembly in the extended state and the stability in the retraction process, the sub-lever is added to the first link 304 and the second link 317 in the present invention. The first ends of the first secondary rod 321 and the second secondary rod 322 may be rotatably connected to the middle portions of the first link 304 and the second link 317, respectively, the ends of the first secondary rod 321 and the second secondary rod 322 are hinged to the supporting plate 306, respectively, and the supporting plate 306 can slide on the first sliding slot 3031 and the second sliding slot 3032, respectively. The first auxiliary rod 321 and the support plate 306 hinged to the end of the first link 304 move on the same slide slot, and the second auxiliary rod 322 and the support plate hinged to the end of the second link 317 also move on the same slide slot.

Fig. 42 is a schematic structural view of a copilot screen magnifying device according to another embodiment of the present invention, in which a manual telescopic assembly is in an extended state.

As shown in fig. 42 and 43, in the present embodiment, the initial state locking mechanism 325 needs to be unlocked manually by the user, and when the initial state locking mechanism 325 is unlocked, the lens holder support 303 can be pushed out by the action of the push-out spring 323 and the damper 324 so as to be gently pushed out to the position where the push-out spring 323 does not have the acting force, and then the lens holder support 303 can be pulled manually until the manual telescopic assembly is pulled to the fully extended state shown in fig. 25, at which time the locking concave wheel 326 and the locking elastic piece 327 can be engaged with the position of the locking lens holder support 303.

A cross-sectional view of the structure of the passenger screen enlarging apparatus according to the present embodiment when the electric telescopic assembly is in the fully extended state is shown in fig. 44. Fig. 44 is a structural sectional view of a copilot screen magnification device according to another embodiment of the present invention, in which a manual retraction assembly is in a fully extended state.

As shown in fig. 45, 46 and 47, in order to ensure the stability of the manual telescopic assembly in the vertical Z direction, in the present invention, a supporting tab and a supporting clamping mechanism may be designed, wherein the supporting tab 319 may be disposed in the first connecting rod 304, and the supporting clamping mechanism 320 may be disposed on the rotating bracket 1.

It should be noted that, when the manual magnifier telescopic rotating bracket 3 is selected as the copilot screen magnifying device of the present invention, the manual magnifier telescopic rotating bracket 3 has a manual telescopic assembly, and when the manual telescopic assembly is in an initial contraction state, the supporting insert 319 is not inserted into the supporting and clamping structure 320, and the locking concave wheel 326 is not in contact with the locking elastic sheet 327.

As shown in fig. 46, when the user manually stretches the manual telescopic assembly to the fully stretched state, the supporting insert 319 can be inserted into the supporting and clamping structure 320 and plays a role of clamping the supporting link rod, and at the same time, the locking concave wheel 326 contacts with the locking elastic sheet 327 to lock and fix the structure.

In addition, in the invention, because different human bodies have different sitting postures on the vehicle seat, the requirement of the magnifying lens on the sight line angle is higher (the sight line is preferably at 90 degrees to the screen, otherwise, the problems of distortion, light reflection and the like are caused). Therefore, when the user uses the copilot screen magnifying device according to the present invention, a function of rotating the screen assembly and the integral mechanism of the magnifying lens together is required.

For the copilot screen amplifying device of the embodiment shown in fig. 1-47, the screen assembly is a mobile phone, and the screen assembly telescopic bracket for clamping and fixing the mobile phone is provided with the screen assembly telescopic mechanism, so that a motor cannot be arranged, and only a manual rotation function is adopted.

As further shown in fig. 19, 50 and 51, although the rotary bracket can rotate around the rotation axis z of the rotary screw 212 relative to the rotary screw 212, the rotary bracket 1 can also be provided with a matching mechanism 11, and the matching mechanism 11 has a shape that is matched with the rotary screw 212 and has a certain softness.

It should be noted that the matching mechanism 11 may be designed in shape to have an initial matching position W1, an upper position W2, and a lower position W3 with the rotating screw 212, as shown in fig. 49. Under certain external force, the rotating bracket 1 can rotate around the rotating shaft z of the rotating screw 212, and the rotating bracket 1 can move the rotating screw 212 from the initial matching position W1 to the upper position W2 or the lower position W3, at which time the rotating screw 212 can still be matched with the matching mechanism 11.

Meanwhile, the fixed support 2 can be provided with the sliding groove 23, the rotating support 1 can be provided with the sliding structure 12, and when the rotating support 1 rotates, the sliding structure 12 of the rotating support 1 can slide in the sliding groove 23 of the fixed support 2, so that the stability of the rotating support 1 during rotation is ensured.
