Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicle accessories, in particular to a rotating structure of a display screen. Background Art

[0002] As the functions of automobiles continue to increase, the in-vehicle display screen not only provides new operation methods for car owners, but also provides diversified services for car owners to improve their driving experience. The existing in-vehicle display screen is usually installed on the instrument panel assembly to facilitate the driver to watch and operate.

[0003] Chinese patent application number CN2019103526651 discloses a vehicle-mounted display device, a rotating mechanism thereof, and a vehicle, which controls the rotation of the display screen through a ball head connection structure to facilitate adjustment of the display screen to an angle that is convenient for the driver or passenger to view.

[0004] The prior art still has the following deficiencies:

[0005] 1. Although the ball joint connection structure can ensure the free movement of the display screen, the rod of the component used for the ball joint connection is usually made thinner in order not to hinder the rotation, so the load-bearing capacity of the connected component is weak. Therefore, the weight of the display screen that can be carried is limited, and it cannot support a heavy display screen, affecting the user's viewing and reading experience.

[0006] 2. Since only one connecting component is used to connect the display screen, if the component is damaged, the display screen will fall off directly. Since there are many fragile electronic components in the display screen, if the display screen collides when it falls off, it is also very easy to cause damage to various electronic components, increasing the user's maintenance cost.

[0007] 3. When the owner uses too much force to move the display screen, causing the display screen to rotate to the maximum rotation angle, the force will be directly applied to the connecting components, which will make it easier for the connecting components to be damaged and affect the user's normal use. Utility Model Content

[0008] The utility model aims to provide a rotating structure of a display screen which has a simple structure, is safe and reliable, and has a stable working state, so as to avoid the situation where the connecting components are damaged due to the fragility of the structure.

[0009] The purpose of this utility model is achieved in this way:

[0010] A rotating structure of a display screen, comprising:

[0011] A fixing seat, which is detachably fixed on the display screen assembly, and a rotating shaft is formed on the upper end of the fixing seat;

[0012] A rotating seat, which is formed with a rotating part, through which the rotating seat can be sleeved on the outside of the rotating shaft, and the rotating seat can be rotated around the rotating shaft;

[0013] A swing seat connected to the connecting portion of the rotating seat, wherein the swing seat can swing around the connecting portion;

[0014] A display screen is arranged on the swing seat, and the display screen can swing along with the swing seat.

[0015] Preferably, the rotating part is a clamping hole, and the clamping hole is used to be sleeved on the outer side of the rotating shaft;

[0016] A locking portion is formed at one end of the rotating seat, and a tightening groove is formed on the locking portion, and the tightening groove is communicated with the clamping hole; when the clamping hole is sleeved on the outside of the rotating shaft, the rotating seat can be clamped on the outside of the rotating shaft by tightening the locking portion.

[0017] Preferably, the outer side wall of the connecting portion is formed into a continuous curved surface, so that the connecting portion is cylindrical;

[0018] The swing seat is formed with a groove 1, and the inner wall of the groove 1 can fit the outer wall of the connecting part;

[0019] A locking block is also provided on the outside of the connecting portion, and the locking block is formed with a second groove, and the inner wall of the second groove can fit the outer wall of the connecting portion;

[0020] When the inner wall of the groove 1 and the inner wall of the groove 2 are both in contact with the outer wall of the connecting portion, the swing seat and the locking block are connected into one piece by the connecting bolts.

[0021] Preferably, a through hole is formed in the locking block, and a positioning groove 1 is formed in a recessed manner on the locking block, and the through hole and the positioning groove 1 are connected to each other;

[0022] A screw connection hole 1 is formed in the swing seat, and a positioning protrusion is formed on the swing seat. The screw connection hole 1 passes through the positioning protrusion, so that the connecting bolt can be screwed with the through hole after passing through the screw connection hole 1;

[0023] When the swing seat and the locking block are connected to each other, the positioning protrusion will be placed in the positioning groove one, and the through hole and the screw hole are coaxial, so that the connecting bolt can be screwed with the through hole after passing through the screw hole one.

[0024] Preferably, a limited position convex block is protruded on the rotating seat;

[0025] A limited rotation part 1 is protruded on the peripheral side of the rotating seat, and the limiting protrusion can abut against the limited rotation part 1 as the rotating seat rotates, thereby limiting the rotation angle of the rotating seat.

[0026] Preferably, the rotating seat is further provided with an extended edge protruding therefrom, the extended edge being provided with a slot, the slot being used to connect a protective cover so that the protective cover can cover the outer sides of the rotating seat and the fixed seat;

[0027] An inserting portion is formed on the inner side of the protective cover, and the inserting portion can be inserted into the slot and rotated together with the rotating seat;

[0028] A movable spring sheet is formed on the plug-in portion, and a clamping protrusion is formed on the spring sheet. When the plug-in portion extends into the slot, the clamping protrusion can abut against the edge of the slot.

[0029] Preferably, the clamping protrusion is formed with a second driving inclined surface;

[0030] When the plug-in portion is disengaged from the slot, the second driving slope contacts the edge of the slot and drives the spring to bend, so that the engaging protrusion gradually moves away from the extending edge, thereby allowing the plug-in portion to be disengaged from the slot.

[0031] Preferably, an inclined support rib is formed on the side wall of the plug-in portion, and the width of the support rib gradually increases from the bottom end to the top end, so that when the plug-in portion is fully inserted into the slot, the bottom end of the support rib and the plug-in portion form an interference fit with the slot.

[0032] Preferably, a second limited rotation part is also formed on the rotating seat. When the swing seat rotates with the connecting part as the axis, the second limited rotation part is located on the rotation path of the swing seat, so that the second limited rotation part can limit the rotation angle of the swing seat.

[0033] Preferably, a cavity is formed inside the fixing seat, and a wire outlet hole is opened on the side wall of the fixing seat, and the cavity is communicated with the wire outlet hole.

[0034] Compared with the prior art, the utility model has the following outstanding and beneficial technical effects:

[0035] 1. The rotating seat in this technical solution is set on the rotating shaft of the fixed seat, and the bottom side end face of the rotating seat abuts against the upper end face of the fixed seat, and the display screen is connected to the connecting part at one end of the rotating seat through the swing seat. The rotating seat is used to drive the display screen to rotate in the horizontal direction, and the swing seat can swing in the vertical direction with the connecting part as the axis. Since the bottom side of the rotating seat directly abuts against the upper end face of the fixed seat, the connection structure between the rotating seat and the rotating shaft will not bear most of the load, and is mainly used to limit the positional relationship between the rotating seat and the fixed seat. The swing seat fits on the connecting part, which can effectively reduce the pressure and increase the structural strength.

[0036] 2. The swing seat and the locking block in the technical solution cooperate to hold the two ends of the connection part tightly. If the connection structure on one end is damaged, the connection structure on the other end can still play the role of fixing the display screen, thereby not affecting the user's use.

[0037] 3. The fixed seat and the rotating seat are respectively formed with a limited rotation part 1 and a limited rotation part 2, which are used to limit the angle of the display screen when it rotates, ensuring that the display screen can always be at an angle that is convenient for the owner to view. When the owner pushes the display screen hard, the limited rotation part 1 and the limited rotation part 2 can also play the role of auxiliary support, improve the structural strength, and prevent the connection components from being damaged due to excessive force by the owner.

[0051] The following are specific embodiments of the present invention, and the technical solution of the present invention is further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0052] like Figure 1-Figure 4 A rotating structure of a display screen is shown, comprising:

[0053] A fixing base 1, which is detachably fixed on the display screen assembly, and a rotating shaft 11 is formed on the upper end of the fixing base 1;

[0054] The rotating seat 2 is formed with a rotating part, through which the rotating seat 2 can be sleeved on the outer side of the rotating shaft 11, and the rotating seat 2 can rotate around the rotating shaft 11;

[0055] The swing seat 3 is connected to the connecting portion 25 of the rotating seat 2, and the swing seat 3 can swing around the connecting portion 25;

[0056] The display screen 6 is arranged on the swing seat 3 , and the display screen 6 can swing along with the swing seat 3 .

[0057] The rotating seat 2 can drive the display screen 6 to rotate in the horizontal direction, while the swing seat 3 can drive the display screen 6 to rotate in the vertical direction. The purpose of adjusting the orientation of the display screen 6 can be achieved through the cooperation between the rotating seat 2 and the swing seat 3.

[0058] In the present technical solution, the lower end face of the rotating seat 2 abuts against the upper end face of the fixed seat 1, and the weight of the display screen 6 can be partially applied to the fixed seat 1, thereby reducing the load that the rotating part needs to bear when connecting with the rotating shaft 11. The rotating shaft 11 only needs to limit the position of the rotating seat 2, so that the rotating seat 2 can only rotate around the rotating shaft 11. The loss of the rotating shaft 11 during use is reduced, and the purpose of extending the service life is achieved.

[0059] like Figure 1-Figure 4 As shown, in this embodiment, the rotating portion is a clamping hole 21, and the clamping hole 21 is used to be sleeved on the outer side of the rotating shaft 11;

[0060] A locking portion 22 is formed at one end of the rotating seat 2, and a tightening groove 23 is formed on the locking portion 22, and the tightening groove 23 is connected to the clamping hole 21; when the clamping hole 21 is sleeved on the outside of the rotating shaft 11, the rotating seat 2 can be clamped on the outside of the rotating shaft 11 by screwing the locking portion 22.

[0061] In this embodiment, a fastening bolt 24 is provided on the locking portion 22. When the holding hole 21 is sleeved on the outside of the rotating shaft 11, the length of the locking portion 22 can be compressed by tightening the fastening bolt 24, and the diameter of the holding hole 21 can be reduced by the tightening groove 23, so that the inner wall of the holding hole 21 fits more closely on the outer wall of the rotating shaft 11, and the friction between the holding hole 21 and the rotating shaft 11 is increased, so that the rotating seat 2 is more tightly held on the outside of the rotating shaft 11, and the magnitude of the friction will not hinder the vehicle owner from pushing the rotating seat 2 to rotate. When the vehicle shakes or bumps, the friction force makes it difficult for the rotating seat 2 to have a relative motion relationship with the fixed seat 1, so as to achieve the effect of fixing the angle of the display screen 6.

[0062] As a preferred embodiment, the cavity 12 of the fixed seat 1 in the present technical solution is arranged toward the instrument panel assembly, so that the rotating shaft 11 faces upward. When the rotating seat 2 is pressed against the top of the fixed seat 1, the rotating seat 2 will be pressed against the upper surface of the fixed seat 1 under the action of gravity, thereby generating friction between the rotating seat 2 and the fixed seat 1, further limiting the rotation of the rotating part 2.

[0063] like Figure 1-Figure 4 As shown, a connecting portion 25 is formed on the rotating seat 2, and the outer side wall of the connecting portion 25 is formed into a continuous curved surface, so that the connecting portion 25 is cylindrical.

[0064] The swing seat 3 is formed with a groove 31, and the inner wall of the groove 31 can fit the outer wall of the connecting portion 25;

[0065] A locking block 4 is also provided on the outside of the connecting portion 25. The locking block 4 is formed with a second groove 41. The inner wall of the second groove 41 can fit the outer wall of the connecting portion 25.

[0066] When the inner wall of groove 1 31 and the inner wall of groove 2 41 both fit the outer wall of the connecting part 25 , the swing seat 3 and the locking block 4 can be connected as one, so that the swing seat 3 and the locking block 4 are wrapped around the connecting part 25 , and the swing seat 3 and the locking block 4 can rotate around the connecting part 25 .

[0067] like Figure 1-Figure 5 As shown, a through hole 42 is formed in the locking block 4 , and a positioning groove 43 is recessed on the locking block 4 , and the through hole 42 is connected to the positioning groove 43 .

[0068] A screw hole 32 is formed in the swing seat 3, and a positioning protrusion 33 is formed on the swing seat 3, and the screw hole 32 passes through the positioning protrusion 33. When the swing seat 3 and the locking block 4 are connected, the positioning protrusion 33 can be placed in the positioning groove 43, thereby determining the position between the through hole 42 and the screw hole 32, ensuring that the through hole 42 and the screw hole 32 are on the same straight line, so that the connecting bolt 44 passes through the through hole 42 and the screw hole 32, and the swing seat 3 and the locking block 4 are screwed together. The display screen 6, the swing seat 3 and the locking block 4 are screwed together to form an integral body, and the pressure when the swing seat 3 and the locking block 4 are tightly held on the peripheral side of the connecting part 25 can also be adjusted, thereby adjusting the magnitude of the friction between the swing seat 3, the locking block 4 and the connecting part 25, and changing the user's hand feeling when turning the display screen 6.

[0069] The groove 31 formed on the swing seat 3 can fit on the side wall of the connecting portion 25, thereby reducing the pressure per unit area, reducing the probability of damage to the connecting portion 25 and the swing seat 3, and extending the service life.

[0070] As a preferred embodiment, the screw hole 32 and the positioning protrusion 33 are coaxial, and the through hole 42 and the positioning groove 43 are coaxial, so that when the positioning protrusion 33 is inserted into the positioning groove 43, the through hole 42 and the screw hole 32 can also be ensured to be on the same axis, so that the connecting bolt 44 can be inserted into the through hole 42 and the screw hole 32.

[0071] Furthermore, the display screen 6 is convexly formed with a screw seat 61, and the end surface of the screw seat 61 is concavely formed with a second screw hole 62. The swing seat 3 is concavely formed with a second positioning groove 34, and the screw seat 61 can be placed in the second positioning groove 34, so that the first screw hole 32 and the second screw hole 62 are on the same axis, so that the connecting bolt 44 can pass through the through hole 42 and be screwed with the first screw hole 32 and the second screw hole 62, so that the locking block 4, the swing seat 3 and the display screen 6 are connected as a whole, and the display screen 6 is driven to swing in the vertical direction.

[0072] Both ends of the connection part 25 are formed with anti-slip convex edges 26. Due to the anti-slip convex edges 26, it is convenient to assemble by screwing the swing seat 3 and the locking block 4 into one piece and wrapping them in the connection part 25. The anti-slip convex edges 26 can also prevent the swing seat 3 and the locking block 4 screwed into one piece from detaching from the connection part 25.

[0073] In the present technical solution, the swing seat 3 can be fitted on the side wall of the connecting portion 25 , and both ends of the swing seat 3 are connected with locking blocks 4 , which cooperate with the swing seat 3 to be connected to the connecting portion 25 .

[0074] As another preferred technical solution, two swing seats 3 are respectively connected to the ends of the connecting portion 25 , and each swing seat 3 is screwed into one with the locking block 4 , so that the swing seat 3 and the locking block are fixed on the connecting portion 25 .

[0075] By using a swing seat 3 and a locking block 4 to connect the display screen 6 to the rotating seat 2, more supporting positions are added. When the connection between the swing seat 3 and the locking block 4 at one place is loose, there is at least another swing seat 3 and locking block 4 that can provide support for the display screen 6 to prevent the display screen 6 from separating from the rotating part 2 and to avoid damage to the display screen 6 due to falling.

[0076] like Figure 1-Figure 6 As shown, a limiting protrusion 14 is protrudingly formed on the rotating seat 2.

[0077] The rotating seat 2 has a limited rotation portion 27 protruding from the circumference thereof. The limiting protrusion 14 can abut against the limited rotation portion 27 as the rotating seat 2 rotates, and limit the rotating seat 2 from further rotation, so that the rotating seat 2 can only rotate within a certain angle range.

[0078] An escape groove 15 is formed on the peripheral side of the fixing seat 1 , and the escape groove 15 is used to leave enough space for the limiting protrusion 14 to move.

[0079] This avoids the risk of the cable connected to the display screen 6 being broken or worn during the pulling process due to the display screen 6 rotating at an excessively large angle, thereby achieving the purpose of reducing cable loss and extending service life.

[0080] Or, when the vehicle bumps, the rotating seat 2 rotates, so that the display screen 6 no longer faces the user, affecting the user's normal use. By setting the rotation limiter 27, the rotation angle of the display screen 6 can also be limited, so that the display screen 6 can always be within the angle range that is convenient for the user to view.

[0081] like Figure 1-Figure 6 As shown, the rotating seat 2 is also protruded with an extension edge 28, and the extension edge 28 is formed with a slot 281, and the slot 281 is used to connect the protective cover 5, so that the protective cover 5 can cover the outer side of the rotating seat 2 and the fixed seat 1;

[0082] An inserting portion 51 is formed on the inner side of the protective cover 5 . The inserting portion 51 can be inserted into the slot 281 and rotates together with the rotating base 2 .

[0083] The protective cover 5 is used to protect the internal structure and prevent foreign matter from colliding with the internal connection structure and causing damage to the internal structure.

[0084] like Figure 4 and Figure 6 As shown, a movable spring sheet 53 is formed on the plug-in portion 51, and a clamping protrusion 54 is formed on the spring sheet 53. When the plug-in portion 51 is inserted into the slot 281, the clamping protrusion 54 can abut against the lower edge of the slot 281, so that the plug-in portion 51 and the extension edge 28 are clamped to prevent the plug-in portion 51 from being separated from the slot 281.

[0085] The clamping protrusion 54 is formed with a first driving inclined surface 55 and a second driving inclined surface 56 .

[0086] During the process of inserting the plug-in part 51 into the slot 281, the first driving bevel 55 can contact the edge of the slot 281 and decompose part of the force applied to the first driving bevel 55 into a horizontal force, so that the spring piece 53 drives the locking protrusion 54 away from the edge of the slot 281, making it easier for the plug-in part 51 to be inserted into the slot 281.

[0087] When the plug-in portion 51 is completely inserted into the slot 281 , the latching protrusion 54 will return to rest against the extending edge 28 to prevent the plug-in portion 51 from being disengaged from the slot 281 .

[0088] When the plug-in portion 51 needs to be disengaged from the slot 281 , the second driving slope 56 will contact the edge of the slot 281 and drive the spring 53 to bend, so that the locking protrusion 54 gradually moves away from the edge of the extension edge 28 , thereby facilitating the plug-in portion 51 to be disengaged from the slot 281 .

[0089] The angle between the first driving inclined surface 55 and the horizontal plane is greater than the angle between the second driving inclined surface 56 and the horizontal plane. Therefore, when the plug-in portion 51 is pulled out from the slot 281, a greater force is required to move the spring piece 53 than when the plug-in portion 51 is inserted into the slot 281.

[0090] Thereby, under normal working conditions, the second driving inclined surface 56 serves to limit the separation of the plug-in portion 51 and the slot 281 .

[0091] As another preferred embodiment, Figure 6As shown, an inclined support rib 52 is formed on the side wall of the plug-in portion 51, and the width of the support rib 52 gradually increases from the top to the bottom, so that when the plug-in portion 51 is fully inserted into the slot 281, the bottom end of the support rib 52 and the plug-in portion 51 form an interference fit with the slot 281, thereby ensuring that the plug-in portion 51 can be stably fixed in the slot 281, ensuring the stability of the connection between the protective cover 5 and the rotating seat 2.

[0092] Specific as Figure 6 As shown, a cavity 12 is formed in the fixing base 1, and a wire outlet hole 13 is opened on the side wall of the fixing base 1, and the cavity 12 is connected with the wire outlet hole 13. When the fixing base 1 is installed on the instrument panel assembly, the cable can enter the cavity 12, and pass through the wire outlet hole 13 to connect with the display screen 6, so as to supply power to the display screen 6 and transmit data. Since the area of ​​the wire outlet hole 13 is large and there is enough space in the cavity 12 for the cable to move, when the display screen 6 is moved, the cable can move freely with the display screen 6.

[0093] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
