Description

Technical Field

[0001] The present application relates to the technical field of flip screens, and in particular to a flip mechanism, a flip screen system and a vehicle. Background Art

[0002] In a car-mounted flip screen system, the motor usually needs to transfer its own power to the display screen through the shaft so that the display screen can flip to the customer's specified position. At the same time, in order to facilitate customers to watch movies and work safely and reliably at the specified position, when the motor power is released, the display screen needs to be locked in the specified position and not shake with external bumps.

[0003] In the related art, the vehicle-mounted flip screen generally uses static damping to lock the display screen at a specified position. Specifically, a static damping ring is provided on the rotating shaft. The static damping ring is used to increase the resistance of the rotating shaft when the rotating shaft rotates on its own after the motor power is released, so as to prevent the rotating shaft from rotating and achieve locking of the rotating shaft.

[0004] However, since the motor needs to overcome the resistance generated by the static damping ring when driving the shaft to rotate, the use of static damping not only increases the load on the motor, reducing the efficiency of the motor driving the shaft to rotate, thereby reducing work efficiency, but also because the static damping ring is easy to wear, has a short service life and requires a high replacement frequency, which also leads to increased costs.

[0028] Compared with the related art, this application has at least the following beneficial effects:

[0029] In the present application, when the flipping mechanism is used in a vehicle-mounted flip screen system, the vehicle-mounted display screen can be installed on the mounting piece, and when the customer needs to flip the display screen, the driving component can be started. In this case, the output shaft of the driving component rotates before the rotating structure. Since the one-way locking structure is used to transmit the rotational power of the driving component to the rotating structure when the output shaft rotates before the rotating structure, the one-way locking structure can transmit the rotational power of the driving component to the rotating structure. The driving component can drive the mounting piece to flip around the rotation axis by driving the rotating structure to rotate, and then drive the display screen installed on the mounting piece to flip, so that the display screen can be flipped to the position specified by the customer.

[0030] When the vehicle is bumpy or the display screen is manually moved, the display screen tends to drive the mounting part to flip over. In this case, the mounting part also tends to drive the rotating structure to rotate before the output shaft. Since the one-way locking structure is also used to lock the rotating structure when the rotating structure rotates before the output shaft, the one-way locking structure can lock the rotating structure at this time, making it impossible for the rotating structure to rotate, and further making it impossible for the mounting part and the display screen mounted on the mounting part to flip around the rotation axis, thereby locking the display screen. In this way, when the vehicle is bumpy or the display screen is manually moved, the display screen can still be kept in the specified position without flipping over, making it convenient for customers to use the display screen safely and reliably at the specified position for watching movies, working, etc.

[0031] From the above description, it can be seen that through the one-way locking structure in the present application, not only can the rotational power of the driving component be transmitted to the rotating structure, so that the driving component drives the mounting member and the display screen installed on the mounting member to flip by driving the rotating structure to rotate, but also the rotating structure can be locked when the vehicle is bumpy or the display screen is manually turned, so that the rotating structure cannot rotate, and then the mounting member and the display screen installed on the mounting member cannot flip, thereby achieving the locking of the display screen. At the same time, compared with the static damping in the related technology, through the one-way locking structure in the present application, not only is there no need to overcome the resistance generated by the static damping ring, thereby not increasing the load of the motor, which is beneficial to improving the driving efficiency of the motor, and then is beneficial to improving work efficiency, but it is also not easy to wear, which is beneficial to increasing the service life, and then is beneficial to reducing costs.

[0052] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

These terms are mainly used to better describe the present application and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific orientation, or to be constructed and operated in a specific orientation.

[0054] In addition, some of the above terms may be used to express other meanings in addition to indicating orientation or positional relationship. For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in this application can be understood according to specific circumstances.

[0055] In addition, the terms "installed", "set", "provided with", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0056] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, "plurality" means two or more.

[0057] As described in the background technology of this application, in a vehicle-mounted flip screen system, the motor usually needs to transfer its own power to the display screen through the rotating shaft so that the display screen can flip to the customer's specified position. At the same time, in order to facilitate the customer to watch movies, work, etc. in a safe and reliable manner at the specified position, when the motor power is released, the display screen needs to be locked in the specified position and not shake with external bumps.

[0058] In the related art, the vehicle-mounted flip screen generally uses static damping to lock the display screen at a specified position. Specifically, a static damping ring is provided on the rotating shaft. The static damping ring is used to increase the resistance of the rotating shaft when the rotating shaft rotates on its own after the motor power is released, so as to prevent the rotating shaft from rotating and achieve locking of the rotating shaft.

[0059] However, since the motor needs to overcome the resistance generated by the static damping ring when driving the shaft to rotate, the use of static damping not only increases the load on the motor, reducing the efficiency of the motor driving the shaft to rotate, thereby reducing work efficiency, but also because the static damping ring is easy to wear, has a short service life and requires a high replacement frequency, which also leads to increased costs.

[0060] Embodiment 1

[0061] In view of the above-mentioned problems, the present application provides a flipping mechanism to solve the problems of reduced work efficiency and increased costs caused by using static damping to lock the display screen in the related art.

[0062] The technical solution of the present application will be further described below in conjunction with specific embodiments and drawings:

[0063] like Figure 1 , Figure 2 as well as Figure 5As shown, the flip mechanism 100 includes a mounting member 1, a driving assembly 2 and a one-way locking structure 3. The mounting member 1 is used to mount the display screen 2001, and a rotating structure 4 is arranged on the mounting member 1, and the rotating structure 4 is rotatably arranged around its own rotating axis. The driving assembly 2 has an output shaft 21, and the one-way locking structure 3 is arranged between the rotating structure 4 and the output shaft 21. The one-way locking structure 3 is used to transmit the rotating power of the driving assembly 2 to the rotating structure 4 when the output shaft 21 rotates before the rotating structure 4, so that the driving assembly 2 drives the rotating structure 4 to rotate and drive the mounting member 1 to flip around the above-mentioned rotating axis. The one-way locking structure 3 is also used to lock the rotating structure 4 when the rotating structure 4 rotates before the output shaft 21, so that the mounting member 1 cannot flip around the above-mentioned rotating axis.

[0064] In the present application, when the flipping mechanism 100 is used in the vehicle-mounted flipping screen system 200, the vehicle-mounted display screen 2001 can be installed on the mounting member 1, and when the customer needs to flip the display screen 2001, the driving component 2 can be started. In this case, the output shaft 21 of the driving component 2 rotates before the rotating structure 4. Since the one-way locking structure 3 is used to transmit the rotational power of the driving component 2 to the rotating structure 4 when the output shaft 21 rotates before the rotating structure 4, the one-way locking structure 3 can transmit the rotational power of the driving component 2 to the rotating structure 4. The driving component 2 can drive the rotating structure 4 to rotate and drive the mounting member 1 to flip around the above-mentioned rotation axis, thereby driving the display screen 2001 installed on the mounting member 1 to flip, so that the display screen 2001 can be flipped to the position specified by the customer.

[0065] When the vehicle is bumpy or the display screen 2001 is manually moved, the display screen 2001 tends to drive the mounting part to flip. In this case, the mounting part 1 also tends to drive the rotating structure 4 to rotate before the output shaft 21. Since the one-way locking structure 3 is also used to lock the rotating structure 4 when the rotating structure 4 rotates before the output shaft 21, the one-way locking structure 3 can lock the rotating structure 4 at this time, making the rotating structure 4 unable to rotate, and further making it impossible for the mounting part 1 and the display screen 2001 installed on the mounting part 1 to flip around the above-mentioned rotation axis, thereby locking the display screen 2001. In this way, when the vehicle is bumpy or the display screen 2001 is manually moved, the display screen 2001 can still be kept in the specified position without flipping, so that customers can use the display screen 2001 safely and reliably at the specified position for watching movies, working, etc.

[0066] From the above description, it can be seen that through the one-way locking structure 3 in the present application, not only can the rotational power of the driving component 2 be transmitted to the rotating structure 4, so that the driving component 2 drives the mounting member 1 and the display screen 2001 installed on the mounting member 1 to flip over by driving the rotating structure 4 to rotate, but also the rotating structure 4 can be locked when the vehicle is bumpy or the display screen 2001 is manually turned, so that the rotating structure 4 cannot rotate, and thus the mounting member 1 and the display screen 2001 installed on the mounting member 1 cannot flip over, thereby realizing the locking of the display screen 2001. At the same time, compared with the static damping in the related art, through the one-way locking structure 3 in the present application, not only is there no need to overcome the resistance generated by the static damping ring, thereby not increasing the load of the motor, which is beneficial to improving the driving efficiency of the motor, and thus is beneficial to improving work efficiency, but it is also not easy to wear, which is beneficial to increasing the service life, and thus is beneficial to reducing costs.

[0067] For the mounting member 1, in a preferred embodiment, as Figure 1 and Figure 2 As shown, the mounting member 1 is a rectangular shell having a shape and size matching that of the display screen 2001, and the display screen 2001 can be embedded and installed in the rectangular shell. Such a configuration can not only ensure the reliability of the display screen 2001 being installed on the mounting member 1, but also the mounting member 1 can provide a certain degree of protection for the display screen 2001, which is conducive to preventing the display screen 2001 from being bumped to a certain extent.

[0068] In other embodiments, the mounting member 1 may also be a clamping claw that mounts the display screen 2001 thereon by clamping and fixing the display screen 2001. Such a configuration can not only ensure the reliability of the installation of the display screen 2001 on the mounting member 1, but also reduce the weight of the mounting member 1, which is conducive to realizing a lightweight design of the flip mechanism 100.

[0069] For the drive assembly 2, in a preferred embodiment, as Figure 1 and Figure 2 As shown, the driving assembly 2 includes a driving member 22 and a reducer (not marked in the figure), the driving member 22 can be any one of a motor, a hydraulic cylinder and a pneumatic cylinder, and the driving member 22 is connected to the reducer by transmission, and the output shaft 21 is the output shaft of the reducer. In this way, not only can the driving member 22 provide power for driving the display screen 2001 to flip, but also the reducer can reduce the power output by the driving member 22 and increase the torque.

[0070] In other embodiments, the driving assembly 2 may also include only the driving member 22, which may be any one of a motor, a hydraulic cylinder, and a pneumatic cylinder, and the output shaft 21 is the output shaft of the driving member 22. Such a configuration can simplify the composition of the driving assembly 2, which is conducive to reducing the manufacturing cost of the driving assembly 2.

[0071] For the one-way locking structure 3, in a preferred embodiment, as Figure 3 , Figure 4 and Figure 5 As shown, the one-way locking structure 3 includes an installation shell 31, a power transmission structure and a locking structure, wherein the installation shell 31 has an installation cavity, the output shaft 21 and the rotating structure 4 can be rotatably arranged in the installation cavity, and the central axis of the output shaft 21 is colinearly arranged with the rotating axis of the rotating structure 4, and the output shaft 21 and the rotating structure 4 are spaced apart and arranged relative to each other.

[0072] The power transmission structure is located in the installation cavity, and the power transmission structure includes a driven transmission part 32 and an active transmission part 33. Figure 3 As shown, the driven transmission part 32 includes a boss 321 and a plurality of force-bearing parts 322. The boss 321 is disposed on the rotating structure 4. The force-bearing parts 322 are disposed on the boss 321 at intervals along the circumference of the boss 321 and protrude from the boss 321 along the radial direction of the boss 321, so that the outer circumferential surface of the boss 321, the inner circumferential surface of the mounting housing 31 and the force-bearing parts 322 together form a plurality of slots 34 ( Figure 5 As shown), the slot width of each slot 34 is in the circumferential direction ( Figure 5 The A direction in the figure gradually decreases from the two ends to the middle. Figure 4 As shown, the active transmission part 33 includes a plurality of force-applying parts 331, each of which is arranged at intervals along the circumference of the output shaft 21 and protrudes from the output shaft 21 along the axial direction of the output shaft 21, and each of the force-applying parts 331 is respectively arranged in each of the slots 34 ( Figure 5 shown).

[0073] like Figure 5 As shown, the locking structure includes a plurality of rolling bodies 35 , each of which is disposed at each end of each slot 34 and is located between each two adjacent force-bearing portions 322 and force-applying portions 331 .

[0074] When the customer needs to flip the display screen, the driving component 2 is started and the output shaft 21 rotates. At this time, a rolling body 35 in each slot 34 is pushed toward the end of the slot 34 by the force-applying portion 331 and away from the inner circumference of the mounting shell 31 and abuts against the force-bearing portion 322. In this way, the output shaft 21 can drive the rotating structure 4 to rotate, and then drive the mounting member 1 and the display screen 2001 installed on the mounting member 1 to flip. At this time, another rolling body 35 in each slot 34 rolls toward the end of the slot 34 to be away from the inner circumference of the mounting shell 31.

[0075] When the vehicle is bumpy or the display screen 2001 is manually moved, the two rolling bodies 35 in each slot 34 roll toward the middle of the slot 34 to abut against the inner circumference of the mounting shell 31 and the outer circumference of the boss 321, so that the rotating structure 4 is locked to the mounting shell 31, that is, the one-way locking structure 3 locks the rotating structure 4, making the rotating structure 4 unable to rotate, and further making the mounting member 1 and the display screen 2001 mounted on the mounting member 1 unable to flip over, thereby locking the display screen 2001.

[0076] It can be seen from the above description that the one-way locking structure 3 is set in this way, not only can the driving component 2 drive the display screen 2001 to flip through the one-way locking structure 3, but also can lock the flipping of the display screen 2001. At the same time, through the rolling body 35 in the one-way locking structure 3, it is not only beneficial to reduce the resistance of the one-way locking structure 3, but also can further reduce the load on the driving component 2, which is beneficial to further improve the driving efficiency of the driving component 2, and further help to further improve the work efficiency, but also can further reduce the wear of the one-way locking structure 3, which is beneficial to further improve the service life, and further help to further reduce the cost.

[0077] In other embodiments, the one-way locking structure 3 may also be a forward transmission bidirectional drive reverse transmission one-way locking mechanism disclosed in the Chinese invention patent application with application publication number CN110748580A. Such a configuration can simplify the structure of the one-way locking structure 3 to a certain extent, which is conducive to the convenience of processing and manufacturing of the one-way locking structure 3.

[0078] Further, in a preferred embodiment, Figure 6 As shown, the flipping mechanism 100 also includes a detection member 5 and a controller (not shown in the figure), wherein the detection member 5 is used to detect the flipping angle of the mounting member 1 around the above-mentioned rotation axis, and the controller is electrically connected to the detection member 5, and the controller is used to control the shutdown of the driving component 2 according to the above-mentioned flipping angle detected by the detection member 5.

[0079] With such arrangement, during the process of the driving component 2 driving the display screen 2001 to flip, the detection component 5 can detect the flipping angle of the display screen 2001 flipping around the above-mentioned rotation axis, that is, the angular position of the display screen 2001 can be detected. When the above-mentioned angular position detected by the detection component 5 corresponds to the specified position of the customer, the controller can control the driving component 2 to shut down so that the display screen 2001 flips to the specified position. Therefore, according to the above, the detection component 5 and the controller are arranged to control the stop position of the display screen 2001 during the flipping process by detecting the angular position of the display screen 2001, which is conducive to improving the accuracy of the stop position of the display screen 2001.

[0080] Further, with respect to the detection element 5, in a preferred embodiment, the detection element 5 is a magnetic encoder.

[0081] Since the magnetic encoder has the advantages of high precision and long life, setting the detection member 5 as a magnetic encoder is not only beneficial to improving the accuracy of the detection member 5 in detecting the angular position of the display screen 2001, but also beneficial to extending the service life of the detection member 5, thereby helping to reduce the cost of the detection member 5.

[0082] In other embodiments, the detection element 5 may also be a photoelectric encoder.

[0083] Since the photoelectric encoder is easy to install and maintain, setting the detection element 5 as a photoelectric encoder is conducive to facilitating the installation and maintenance of the detection element 5.

[0084] For the rotating structure 4, further, in a preferred embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the rotating structure 4 is the first rotating shaft, the central axis of the first rotating shaft is the above-mentioned rotating axis, one axial end of the first rotating shaft is connected to the mounting member 1, and the one-way locking structure 3 is arranged between the output shaft 21 and the other axial end of the first rotating shaft.

[0085] The rotating structure 4 is set as the first rotating shaft. Since the rotating shaft has a simple structure, it is convenient for processing and manufacturing the rotating structure 4. Since the rotating shaft has good stability, it can also improve the stability of the rotating structure 4, which is beneficial to improve the stability of the flipping of the display screen 2001.

[0086] In other embodiments, the rotating structure 4 may also be a ball joint. Since the ball joint has good wear resistance and can maintain stable performance during long-term use, the rotating structure 4 is set as a ball joint, which can make the rotating structure 4 have good wear resistance and can also make the rotating structure 4 maintain stable performance during long-term use, thereby making the display screen 2001 maintain flip stability during long-term flip use.

[0087] Regarding the setting position of the detection member 5, in one embodiment, the detection member 5 is set on the first rotating shaft, and the detection member 5 is used to detect the flipping angle of the mounting member 1 around the above-mentioned rotating axis by detecting the rotating angle of the first rotating shaft.

[0088] In this way, the detection member 5, the driving assembly 2, the one-way locking structure 3 and the rotating structure 4 can be integrated on one side of the mounting member 1, which is conducive to improving the integration of the flip mechanism 100. By detecting the rotation angle of the first rotating shaft to detect the flip angle of the mounting member 1, it is convenient for the detection member 5 to detect the flip angle of the mounting member 1, and further, it is convenient for the detection member 5 to detect the flip angle of the display screen 2001.

[0089] In a preferred embodiment, Figure 1 , Figure 2as well as Figure 6 As shown, the flip mechanism 100 further includes a second rotating shaft 6 , which is connected to the mounting member 1 , and the second rotating shaft 6 and the first rotating shaft are coaxially arranged, and the second rotating shaft 6 and the first rotating shaft are respectively arranged on both sides of the mounting member 1 .

[0090] The detection member 5 is disposed on the second rotating shaft 6 , and is used for detecting the turning angle of the mounting member 1 around the above-mentioned rotating axis by detecting the turning angle of the second rotating shaft 6 .

[0091] In this way, the first rotating shaft and the second rotating shaft 6 can further improve the stability of the mounting member 1 when flipping, and thus can also improve the stability of the display screen 2001 when flipping. The detection member 5 is arranged on the second rotating shaft 6, which not only facilitates the arrangement of the detection member 5, but also facilitates the detection of the flip angle of the mounting member 1 by detecting the rotation angle of the second rotating shaft 6.

[0092] For the second rotating shaft 6, further, in a preferred embodiment, as Figure 6 As shown, a central through hole 61 is provided on the second rotating shaft 6, and the length direction of the central through hole 61 is along the length direction of the second rotating shaft 6 ( Figure 6 The central through hole 61 allows a wiring harness connected to the display screen 2001 to pass through.

[0093] Such a configuration can not only reduce the weight of the second rotating shaft 6, which is beneficial to realizing a lightweight design of the flipping mechanism 100, but also can hide the wiring harness while preventing the wiring harness from affecting the normal flipping of the display screen 2001, which is beneficial to improving the aesthetics.

[0094] In other embodiments, the second rotating shaft 6 is a solid shaft, and the wire harness connected to the display screen 2001 can be routed through other routing paths. Since the routing of the wire harness is a prior art, this embodiment of the application will not be elaborated on this. Setting the second rotating shaft 6 as a solid shaft is conducive to enhancing the strength of the second rotating shaft 6, thereby ensuring the normal flipping of the mounting member 1 and the display screen 2001.

[0095] Furthermore, if Figure 6 As shown, the flip mechanism further includes a protective shell 7 , which is disposed at an axial end of the second rotating shaft 6 away from the mounting member 1 , and the protective shell 7 is rotationally matched with the second rotating shaft 6 , and the detection member 5 is disposed in the protective shell 7 .

[0096] With such arrangement, the protective shell 7 can protect the detection member 5, which is beneficial to avoid damage to the detection member 5, and can also reduce interference of external factors on the detection member 5, thereby ensuring detection accuracy.

[0100] In the present application, the one-way locking structure 3 can not only transmit the rotational power of the driving component 2 to the rotating structure 4, so that the driving component 2 drives the mounting member 1 and the display screen 2001 installed on the mounting member 1 to flip over by driving the rotating structure 4 to rotate, but also can lock the rotating structure 4 when the vehicle is bumpy or the display screen 2001 is manually turned, so that the rotating structure 4 cannot rotate, and further the mounting member 1 and the display screen 2001 installed on the mounting member 1 cannot flip over, thereby achieving the locking of the display screen 2001. At the same time, compared with the static damping in the related art, the one-way locking structure 3 in the present application not only does not need to overcome the resistance generated by the static damping ring, thereby not increasing the load of the motor, which is beneficial to improving the driving efficiency of the motor, and further beneficial to improving work efficiency, but also is not easy to wear, which is beneficial to increasing the service life, and further beneficial to reducing costs.
