[0050] As described in the background technology of this application, in the display device of the related art, the design of screen vibration feedback is usually to set a motor on the screen, the screen is fixed on the shell, and the motor is used to drive the screen to vibrate to achieve vibration feedback of the screen.

[0051] However, since the screen is fixed on the shell, the screen and the shell form an integrated structure, the motor needs to drive the screen and the shell to vibrate together to achieve the vibration of the screen. Moreover, since driving the shell to vibrate will also consume part of the vibration energy, the motor will require greater power. A higher-power motor will not only increase the difficulty of motor design, but also increase manufacturing costs because higher-power motors will generally increase in price.

[0052] Embodiment 1

[0053] In view of the above-mentioned problems, the present application provides a display device to solve the problem in the related art that the motor needs to drive the screen and the shell to vibrate together, which causes the motor to require a larger power.

[0054] The technical solution of the present application will be further described below in conjunction with specific embodiments and drawings:

[0055] like Figure 1 , Figure 2 and Figure 3 As shown, the display device includes a housing 1, a screen 2, a connecting structure 3, a buffer 4 and a vibrator 5. The housing 1 has a first fixing portion 11, the screen 2 and the housing 1 together form an installation cavity 6, and the screen 2 has a second fixing portion 21. The connecting structure 3 is connected between the first fixing portion 11 and the second fixing portion 21 to connect the screen 2 to the housing 1, and the connecting structure 3 is movably connected to at least one of the first fixing portion 11 and the second fixing portion 21. The buffer 4 abuts between the first fixing portion 11 and the second fixing portion, the vibrator 5 is arranged in the installation cavity 6, and the vibrator 5 is used to drive the screen 2 to vibrate.

[0056] In the display device of the present application, since the connecting structure 3 is connected between the first fixing part 11 of the shell 1 and the second fixing part 21 of the screen 2, so that the screen 2 is connected to the shell 1, and since the connecting structure 3 is movably connected to at least one of the first fixing part 11 and the second fixing part 21, the connecting structure 3 can not only realize the connection between the screen 2 and the shell 1, but also realize the movable connection between the screen 2 and the shell 1, that is, the screen 2 can be moved relative to the shell 1.

[0057] Since the movable connection between the screen 2 and the shell 1 enables the screen 2 to move relative to the shell 1, and since the buffer 4 abuts between the first fixed portion 11 and the second fixed portion 21, that is, the buffer 4 abuts between the shell 1 and the screen 2, when the vibrator 5 drives the screen 2 to vibrate, the screen 2 that is movable relative to the shell 1 is conducive to achieving vibration isolation between the screen 2 and the shell 1 through the buffering effect of the buffer 4, that is, it is conducive to achieving independent vibration of the screen 2, which is conducive to the driver 5 only needing to drive the screen 2 to achieve the vibration of the screen 2, and there is no need to drive the screen 2 and the shell 1 to vibrate together, which is conducive to reducing the consumption of vibration energy. Therefore, the vibrator 5 does not need more power to a certain extent, which is conducive to reducing the design difficulty of the vibrator 5 and reducing the manufacturing cost.

[0058] Further, if Figure 2 As shown, the display device further includes a main board 7 located in the mounting cavity 6 , the vibrator 5 is disposed on the surface of the screen 2 and connected to the screen circuit and the main board 7 , and an escape hole for evading the vibrator 5 is disposed on the main board 7 .

[0059] First, arranging the vibrator 5 on the surface of the screen 2 is conducive to simplifying the transmission structure between the vibrator 5 and the screen 2, facilitating the manufacture of the display device, and also facilitating the vibration drive of the screen 2 by the vibrator 5. Second, connecting the vibrator 5 to the screen circuit, so that the vibrator 5 can not only work in coordination with the screen circuit to ensure the synchronization of the vibration feedback with the display and interaction of the screen 2, but also trigger the corresponding vibration feedback according to the operations and events on the screen 2. Third, connecting the vibrator 5 to the main board 7, so that the vibrator 5 can not only receive the control signal from the main board 7 to determine when to start the vibration feedback, but also obtain the power supply and transmit data with the main board 7 to support the normal operation of the vibration function. In addition, it can also be integrated with other components on the main board 7 to jointly realize the overall function of the device.

[0060] Regarding the setting of the vibrator 5, in other embodiments, the vibrator 5 is set on a mounting frame, and the mounting frame is set on the surface of the screen 2, that is, the vibrator 5 is set on the surface of the screen 2 through the mounting frame. Such a setting is conducive to facilitating the setting of the vibrator 5 on the screen 2.

[0061] As for the type of the vibrator 5, in a preferred embodiment, the vibrator 5 is a vibration motor. Such an arrangement can make the structure of the vibrator 5 relatively simple, which is convenient for installation and maintenance, and can also make the vibrator 5 have a relatively small volume, that is, the vibrator 5 can occupy less space and is convenient for installation in a limited space.

[0062] In other embodiments, the vibrator 5 may also be an eccentric rotor vibrator, a linear vibrator or a piezoelectric vibrator, etc. The type of the vibrator 5 can be selected flexibly, and can be selected according to actual use requirements, which will not be elaborated in detail in the embodiments of the present application.

[0063] Regarding the material of the buffer 4, in the embodiment of the present application, the material of the buffer 4 can be rubber, polyurethane or foam material, etc. The material selection of the buffer 4 is relatively flexible, and can be selected according to actual use requirements, and the embodiment of the present application will not be elaborated in detail.

[0064] For the connection structure 3, further, as Figure 2 and Figure 3 As shown, the connection structure 3 includes a connection member 31 , and the connection member 31 includes a rod portion 311 and a head portion 312 connected to the rod portion 311 .

[0065] like Figure 4As shown, the first fixing portion 11 includes an avoidance through hole 111 disposed on the housing 1, and the avoidance through hole 111 is for the rod portion 311 to pass through, so that the first fixing portion 11 and the connecting structure 3 can be movably connected, and the head portion 312 is located outside the installation inner cavity 6. The second fixing portion 21 is connected to the rod portion 311, and the head portion 312 is limitedly matched with the housing 1, so that the connecting structure 3 is connected between the first fixing portion 11 and the second fixing portion 21.

[0066] The connecting structure 3 is configured as a connecting member 31 including a rod portion 311 and a head portion 312, so that the connecting member 31 can not only realize the connection between the first fixing portion 11 and the second fixing portion 21, that is, the connection between the screen 2 and the shell 1 can be realized, but also realize the movable connection between the connecting structure 3 and the first fixing portion 11. More importantly, the specific structure of the connecting structure 3 can be simplified, and then the structure of the first fixing portion 11 and the second fixing portion 21 connected to the connecting structure 3 can be simplified, which is conducive to facilitating the manufacture of the display device.

[0067] In a preferred embodiment, the connecting member 31 is a bolt, that is, the rod 311 is a threaded rod, the head 312 is a bolt head, and the second fixing portion 21 is provided with an internal threaded hole that is threadedly matched with the rod 311. The connecting member 31 is set as a bolt, and the threaded match between the rod 311 and the internal threaded hole on the second fixing portion 21 can ensure the connection effect between the connecting member 31 and the second fixing portion 21, and thus ensure the connection effect between the screen 2 and the housing 1, and at the same time can achieve the connection between the screen 2 and the housing 1. Figure 3 Positioning in the Z direction.

[0068] In other embodiments, the rod 311 may be a smooth rod with a smooth outer surface, and a socket for the rod 311 to be inserted is provided on the second fixing portion 21, and the rod 311 and the socket are interference fit. Such a configuration can simplify the structure of the connector 31 and facilitate the processing of the connector 31.

[0069] As for the connection structure 3, in other embodiments, the connection structure 3 includes a card slot and a claw for snap-fitting, one of which is provided at the first fixing portion 11, and the other is provided at the second fixing portion 21, and the card slot and the claw can be movably matched along the arrangement direction of the screen 2 and the housing 1. The connection structure 3 is arranged in this way, and the snap-fitting of the card slot and the claw facilitates the connection between the screen 2 and the housing 1.

[0070] For the configuration of the head 312, further, as Figure 3 and Figure 4 As shown, a groove 14 is provided on the outer surface of the housing 1 , an opening of one end of the avoiding through hole 111 is provided on the bottom wall of the groove 14 , and the head 312 is located in the groove 14 .

[0071] With such a configuration, the head 312 can be hidden in the groove 14 and will not be exposed on the outer surface of the housing 1 , which is beneficial to improving the aesthetics of the display device.

[0072] Regarding the structure of the buffer member 4, further, as Figure 3 and Figure 5 As shown, the buffer 4 includes a first large diameter section 41, a small diameter section 42 and a second large diameter section 43 which are connected in sequence along the axial direction of the rod portion 311, wherein the first large diameter section 41 is located outside the installation inner cavity 6 and abuts between the shell 1 and the head, the small diameter section 42 is arranged between the inner circumferential wall of the avoidance through hole 111 and the outer circumference of the rod portion 311, and the second large diameter section 43 is located in the installation inner cavity 6 and abuts between the first fixing portion 11 and the second fixing portion 21.

[0073] By configuring the buffer 4 in this way, on the one hand, the first large diameter section 41 can be used to isolate the vibration between the shell 1 and the head; on the other hand, the small diameter section 42 can be used to isolate the vibration between the inner circumferential wall of the avoidance hole 111 and the outer circumference of the rod 311; on the third hand, the second large diameter section 43 can be used to isolate the vibration between the first fixing part 11 and the second fixing part 21; in this way, the buffer 4 can further enhance the vibration isolation effect between the shell 1 and the screen 2, which is beneficial to further reduce the consumption of vibration energy.

[0074] In other embodiments, the buffer 4 may include only the small diameter section 42 and the second large diameter section 43, or the buffer 4 may include only the second large diameter section 43. The structure of the buffer 4 is flexible, and can be configured according to actual use requirements, which will not be described in detail in the embodiments of the present application.

[0075] Regarding the setting position of the buffer member 4, further, as Figure 2 As shown, the housing 1 includes a bottom shell 12 and a side shell 13 connected to the bottom shell 12 . The first fixing portion 11 is disposed on the bottom shell 12 . The bottom shell 12 and the screen 2 are disposed on both sides of the side shell 13 .

[0076] like Figure 2 and Figure 3 As shown, the second fixing portion 21 includes a fixing protrusion 211 protruding from the screen 2 , the fixing protrusion 211 is connected to the rod portion 311 , and the buffer member 4 abuts between the first fixing portion 11 and the fixing protrusion 211 .

[0077] In the arrangement direction of the housing 1 and the screen 2, since the area of ​​the bottom housing 12 is larger than that of the side housing 13, the first fixing portion 11 is arranged on the bottom housing 12, which facilitates the arrangement of the first fixing portion 11 on the housing 1. Since the side housing 13 is arranged between the bottom housing 12 and the screen 2, and since there is a relatively small distance between the fixing protrusion 211 and the bottom housing 12, the buffer 4 is indirectly abutted against the screen 2 through the fixing protrusion 211, which facilitates the abutment of the buffer 4 against the screen 2, and also enables the buffer 4 to have a smaller size in the arrangement direction of the housing 1 and the screen 2, which is beneficial to reducing the amount of material used for the buffer 4, and further beneficial to reducing costs.

[0078] In other embodiments, the first fixing portion 11 is disposed on the side shell 13, that is, the buffer member 4 is in contact between the side shell 13 and the screen 2. In this case, the fixing protrusion 211 may not be provided on the screen 2. In this arrangement, since the fixing protrusion 211 may not be provided on the screen 2, it is helpful to simplify the structural arrangement on the screen 2 and facilitate the processing of the screen 2.

[0079] Furthermore, if Figure 2 , Figure 3 and Figure 4 As shown, the first fixing portion 11 further includes a boss 112 protruding from the inner surface of the bottom shell 12 , one end opening of the through hole 111 is disposed on the table surface of the boss 112 , and the buffer member 4 abuts between the boss 112 and the fixing protrusion 211 .

[0080] Since there is a relatively small distance between the boss 112 and the fixed protrusion 211, the buffer member 4 abutting against the fixed protrusion 211 abuts against the bottom shell 12 through the boss 112, which facilitates the abutment with the bottom shell 12 and also enables the buffer member 4 to have a smaller size in the arrangement direction of the shell 1 and the screen 2, which is beneficial to further reduce the material usage of the buffer member 4 and further reduce the cost.

[0081] In other embodiments, the inner surface of the bottom shell 12 is a plane, and the buffer member 4 abuts against the inner surface of the bottom shell 12 which is a plane. This arrangement can simplify the structure of the bottom shell 12 and facilitate the processing of the bottom shell 12.

[0082] Furthermore, if Figure 2 , Figure 3 and Figure 6 As shown, the display device further includes a positioning tube 8 , which is sleeved on the outer peripheral wall of the boss 112 , and one end of the fixing protrusion 211 is located in the positioning tube 8 .

[0083] like Figure 6As shown, a plurality of positioning protrusions 81 are arranged on the inner wall of the positioning cylinder 8 at intervals along the circumference of the positioning cylinder 8, or an annular protrusion is arranged on the inner wall of the positioning cylinder 8 along the circumference of the positioning cylinder 8; the annular protrusion or each positioning protrusion 81 abuts against the fixing protrusion 211 to position the fixing protrusion 211 in a direction perpendicular to the axial direction of the positioning cylinder 8.

[0084] The annular protrusion or each positioning protrusion 81 abuts against the fixing protrusion 211, and since the fixing protrusion 211 can be positioned in a direction perpendicular to the axial direction of the positioning tube 8, that is, it can be positioned in a direction perpendicular to the axial direction of the positioning tube 8. Figure 3 The fixing protrusion 211 is positioned in the X direction and the Y direction, so that when the screen 2 vibrates, it is helpful to prevent the screen 2 from vibrating along the X direction and the Y direction, and further helps to ensure the vibration direction of the screen 2.

[0085] Furthermore, if Figure 6 As shown, a plurality of positioning protrusions 81 are arranged on the inner wall of the positioning tube 8 at intervals along the circumferential direction of the positioning tube 8 .

[0086] like Figure 3 and Figure 6 As shown, the positioning cylinder 8 includes a fixed cylinder section 82 and a plurality of elastic arms 83, each elastic arm 83 is connected to the fixed cylinder section 82, and each elastic arm 83 is arranged at intervals along the circumference of the fixed cylinder section 82, each positioning protrusion 81 is arranged one by one on each elastic arm 83, and the fixed cylinder section 82 is sleeved on the outer peripheral wall of the boss 112.

[0087] In this way, on the one hand, the fixing cylinder section 82 facilitates the sleeve connection of the positioning cylinder 8 on the outer peripheral wall of the boss 112; on the other hand, each positioning protrusion 81 is arranged on each elastic arm 83 one by one, so that not only can the fixing protrusion 211 be aligned along the fixing protrusion 211 through each positioning protrusion 81 on each elastic arm 83, but also can be adjusted by the positioning protrusion 81 on each elastic arm 83. Figure 3 The housing 1 and the screen 2 are positioned in the X and Y directions, and since each elastic arm 83 is easily elastically deformed, the elastic deformation of each elastic arm 83 can further reduce shock and buffer the space between the housing 1 and the screen 2, which is beneficial to further achieve vibration isolation between the housing 1 and the screen 2.

[0088] In other embodiments, the positioning tube 8 is cylindrical in shape as a whole, in which case, a plurality of positioning protrusions 81 or an annular protrusion may be provided on the inner wall of the positioning tube 8. Such a configuration can simplify the structure of the positioning tube 8 and facilitate the processing of the positioning tube 8.

[0089] like Figure 1 and Figure 2 As shown, a buffer ring 9 is provided between the circumferential edge of the screen 2 and the housing 1 .

[0090] With such arrangement, on the basis of the buffering of the buffer member 4 , the buffer ring 9 can further provide shock absorption and buffering between the shell 1 and the screen 2 , thereby facilitating further vibration isolation between the shell 1 and the screen 2 .

[0091] Furthermore, the buffer ring 9 is a foam buffer ring.

[0092] Setting the buffer ring 9 as a foam buffer ring can make the buffer ring 9 lighter, which is conducive to realizing a lightweight design of the display device.

[0093] In other embodiments, the material of the buffer ring 9 may also be rubber or polyurethane, etc. The material selection of the buffer ring 9 is relatively flexible. Specifically, it can be selected according to actual usage requirements, and the embodiments of the present application will not elaborate on this.

[0094] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
