Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, and specifically relates to a locking component, a housing, an electric locking lifting mechanism, and a vehicle-mounted ceiling-mounted TV. Background Technology

[0002] Car ceiling-mounted TVs are common entertainment systems in high-end cars. Existing car ceiling-mounted TVs are typically mounted on the car's roof in a rotating manner. When watching TV, the screen can be flipped down to open, making it nearly perpendicular to the roof for viewing; when not watching TV, it can be flipped up to close, fitting snugly against the roof to avoid obstructing passengers. Furthermore, when the car ceiling-mounted TV is closed, a locking mechanism is usually required to secure it and prevent vibration and noise during vehicle movement.

[0003] Existing locking mechanisms are typically electrically operated telescopic mechanisms, using telescopic movements to release and lock the ceiling-mounted TV. However, in real-world applications, ceiling-mounted TVs often fail to close completely due to structural issues, assembly problems, or increased usage. Therefore, relying solely on a telescopic locking mechanism is often insufficient to ensure the TV screen reaches the intended closed position. Utility Model Content

[0073] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0074] In the prior art, in order to prevent the car-mounted ceiling TV from shaking and making abnormal noises due to the movement of the car when it is in the closed state, a locking mechanism is usually required to fix the TV.

[0075] The inventors discovered that existing locking mechanisms mostly employ electrically telescopic structures, using a telescopic motion to release and lock the ceiling-mounted TV. However, this design has some problems in practical applications. With increased usage time, the ceiling-mounted TV may fail to close completely due to structural deformation, assembly errors, or frequent use. In such cases, relying solely on a simple telescopic structure often fails to bring the TV screen to the intended closed position, resulting in poor locking performance.

[0076] Implementation Method 1

[0077] To address the aforementioned problems, the first aspect of this embodiment discloses a locking element 1, such as... Figure 1 and Figure 3 As shown, it includes:

[0078] The main body 11 can be pushed by the drive component 3 and move relative to the housing;

[0079] A rotating part 12 is provided on the main body 11 and is used to match the externally provided limiting part 22;

[0080] When the main body 11 is pushed to the rotating position, the rotating part 12 and the limiting member 22 abut against each other. Under the continued pushing of the driving assembly 3, the main body 11 rotates along the rotating part 12 to push the external mechanism to be locked to the locking position. The locking member 1 can be driven by external force to abut against the external mechanism to be locked and push the external mechanism to the locking position.

[0081] In this embodiment, the movement of the body 11 is divided into two stages by the arrangement of the rotating part 12:

[0082] Phase 1: As Figure 7 As shown, the drive assembly 3 drives the body 11 to move from the initial position to the rotation position, so that the rotating part 12 abuts against the externally provided limiting member 22; at this time, the body 11 is inserted into the external mechanism to be locked and is ready for the next stage of locking.

[0083] Phase Two: As Figure 8 As shown, the drive assembly 3 continues to push the body 11 to move, but since the rotating part 12 abuts against the limiting member 22, the limiting member 22 restricts the rotating part 12 from continuing to move. Therefore, when the drive assembly 3 continues to push the body 11 to move, the body 11 will rotate about the rotating part 12 as the rotation axis. At this time, the body 11 inserted into the external mechanism in the first stage rotates and pushes the external mechanism to the locking position and locks the external mechanism.

[0084] Existing locking mechanisms typically employ a telescopic structure to achieve the locking action. Specifically, the drive assembly 3 drives the locking member to move linearly and insert into the locking hole of the external mechanism. Once the locking member reaches the set position, the external mechanism is locked. The inventors have discovered that such existing locking mechanisms generally rely solely on the insertion of the locking member into the locking hole of the external mechanism to restrict its rotation. Taking a car-mounted TV as an example, the screen is typically mounted on the vehicle roof and can be flipped down to open. However, when using the existing locking mechanism described above to lock the screen, gaps between the locking hole and the locking member due to structural inaccuracies or assembly errors may cause the screen to vibrate and produce abnormal noises during vehicle operation. Furthermore, with increased use, the screen's rotational damping decreases, weakening its static holding force. This may cause the screen to sag under its own weight, making it unable to maintain the set locking position and leaving the screen in a state where it cannot be fully closed.

[0085] In this embodiment, the locking member 1, through the rotating part 12, can divide its movement into two stages. The first stage is linear motion, where the driving component 3 drives the body 11 to move linearly so that the body 11 is inserted into the locking hole of the vehicle ceiling-mounted TV. The second stage is rotational motion, where the driving component 3 drives the body 11 to rotate about the rotating part 12 as the rotation axis, so that the part of the body 11 inserted into the locking hole can abut against the inner wall of the locking hole and push the screen to rotate and lift to the locked position. Unlike existing locking structures, the locking member 1 in this embodiment adds rotational motion to the linear motion, which can push the screen to rotate and lift to the locked position. When the screen has sufficient rotational damping, the screen can remain in the locked position by its own rotational damping. At this time, when the locking member 1 rotates in the second stage and abuts against the inner wall of the locking hole, the locking member 1 can lock the screen and abut against the screen to keep the screen in the locked position. When the screen cannot remain in the set locking position, the locking member 1, during the second stage of rotation, can abut against the inner wall of the locking hole and push the screen to rotate and lift to the locking position. In summary, the locking member 1 in this embodiment, through the setting of the rotating part 12, divides the movement of the locking member 1 into two stages: linear movement and rotational movement. This solves the problem of unreliable locking in the prior art, ensures that the screen can be stably locked in the closed state, and avoids shaking and abnormal noise during the movement of the car.

[0086] It is worth mentioning that in the above embodiment, the driving component 3 pushes the locking member 1 to move and insert it into the locking hole of the screen to lock the screen. However, in some other embodiments, the screen does not need to have a locking hole for cooperating with the locking member 1. Instead, it cooperates with the locking member 1 through a locking part on the vehicle ceiling-mounted TV. This locking part can be the screen's outer shell or other components set on the outer shell, and its function is to provide a part that can cooperate with the locking member 1. Therefore, in practical applications, the form of this locking part can be diverse, such as the locking hole mentioned in the above embodiment for cooperating with the locking member 1; or a specific component formed or separately set on the outer shell of the vehicle ceiling-mounted TV for cooperating with the locking member 1.

[0087] Accordingly, in this embodiment, a housing 2 is also provided, adapted to the locking member 1, specifically, as shown in the example below. Figure 2 and Figure 3 As shown, the housing 2 includes:

[0088] The housing 21 is used to install the locking member 1 and the drive assembly 3. The locking member 1, which is disposed inside the housing 21, can be pushed by the drive assembly 3.

[0089] A limiting component 22 is disposed inside the housing 21 and is used to match the rotating part 12 of the locking component 1;

[0090] When the locking member 1 is pushed to the rotating position, the rotating part 12 and the limiting member 22 abut against each other and rotate under the continued pushing of the driving component 3, so as to push the external mechanism to be locked by the locking member 1 to the locking position.

[0091] In this embodiment, the housing 2 provides an installation location for the locking member 1 and the drive assembly 3 using the outer shell 21. By setting the limiting member 22, the movement of the locking member 1 is divided into two stages: linear movement and rotational movement, through the cooperation of the limiting member 22 and the rotating part 12. This solves the problem of unreliable locking in the prior art, ensures that the screen can be stably locked in the closed state, and avoids shaking and abnormal noise during the movement of the car. It also solves the problem of not being able to lock when the screen is not fully closed. At the same time, the locking member 1 improves the locking fault tolerance rate.

[0092] Accordingly, the third aspect of this embodiment also discloses an electric locking mechanism, such as... Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, including:

[0093] Locking member 1, the locking member 1 includes a body 11 and a rotating part 12 disposed on the body 11;

[0094] Drive component 3 is used to push the locking element 1 to move;

[0095] The housing 2 described above is used to install the locking element 1 and the drive assembly 3;

[0096] The housing 2 includes:

[0097] The limiting component 22 is matched with the rotating part 12;

[0098] When the locking member 1 is pushed to the rotating position, the rotating part 12 and the limiting member 22 abut against each other and rotate under the continued pushing of the driving component 3, so as to push the external mechanism to be locked by the locking member 1 to the locking position.

[0099] In this embodiment, the electric locking mechanism uses the drive component 3 to drive the locking member 1 to move, and utilizes the cooperation between the limiting component 22 and the rotating part 12 to divide the movement of the locking member 1 into two stages: linear movement and rotational movement. This solves the problem of unreliable locking in the prior art, ensures that the screen can be stably locked in the closed state, and avoids shaking and abnormal noise during the movement of the car.

[0100] Accordingly, the fourth aspect of this embodiment also discloses a vehicle-mounted ceiling-mounted television, including a screen and the aforementioned electric locking mechanism. This vehicle-mounted ceiling-mounted television, through the electric locking mechanism, utilizes the cooperation between the limiting component 22 and the rotating part 12 to divide the movement of the locking member 1 into two stages: linear movement and rotational movement. This solves the problem of unreliable locking in the prior art, ensuring that the screen can be stably locked in the closed state, preventing shaking and abnormal noise during vehicle movement.

[0101] Implementation Method 2

[0102] This embodiment discloses a locking member 1, a housing 2 cooperating with the locking member 1, an electric locking mechanism having the locking member 1 and the housing 2, and a vehicle-mounted ceiling-mounted TV using the electric locking mechanism. This embodiment is a further improvement based on the first embodiment, the improvement being that the locking member 1 and the housing 2 are further confined so that the locking member 1 can move smoothly and steadily within the housing 2. Specifically, as... Figure 6 As shown, the housing 2 also includes:

[0103] The limiting member 23 is used to cooperate with the two sides of the body 11 located in the direction of the rotation axis of the rotating part 12 to limit the movement of the locking member 1 in the direction of the rotation axis of the rotating part 12.

[0104] In this embodiment, by setting the limiting component 23, which abuts against both sides of the main body 11 located in the direction of the rotation axis of the rotating part 12, the movement of the locking member 1 in the axial direction of the rotating part 12 is restricted. This ensures that the locking member 1 does not undergo axial displacement during the linear movement process in the first stage and the rotation process in the second stage, thus ensuring the stability of the movement of the locking member 1 and guaranteeing the locking effect of the locking member 1. Accordingly, by setting the limiting component 23, the movement of the locking member 1 in the direction of the rotation axis of the rotating part 12 can be effectively restricted, ensuring that the locking member 1 remains stable during rotation, avoiding displacement or loosening due to external forces, improving the reliability of the electric locking mechanism, reducing the risk of failure due to loosening of the locking member 1, and improving the overall stability and safety of the system.

[0105] Accordingly, such as Figure 6 As shown, the body 11 also includes:

[0106] Main body 112;

[0107] Locking tongue 111 is provided on the main body;

[0108] On both sides of the main body 112, along the rotation axis of the rotating part 12, there are mechanisms for engaging with the housing 2 to restrict the movement of the locking member 1 along the rotation axis of the rotating part 12. Specifically, the main body 112 can engage with the limiting member 23 of the housing 2, and the limiting member 23 can abut against both sides of the main body 112 along the rotation axis to restrict the movement of the locking member 1 along the axial direction of the rotating part 12.

[0109] In some preferred embodiments, such as Figure 4 and Figure 6 As shown, the main body 112 includes at least a first component 1121 and a second component 1122;

[0110] The limiting component 23 includes:

[0111] The first limiting part 231 is used to cooperate with the first component 1121 on both sides in the direction of the rotation axis of the rotating part 12;

[0112] The second limiting part 232 is used to cooperate with the second component 1122 on both sides in the direction of the rotation axis of the rotating part 12.

[0113] Specifically, the main body 112 includes at least a first component 1121 and a second component 1122; correspondingly, the limiting component 23 includes a first limiting part 231 and a second limiting part 232 that respectively cooperate with the first component 1121 and the second component 1122. The first limiting part 231 can abut against both sides in the direction of the rotation axis of the first component 1121 to limit the movement of the locking member 1 in the axial direction of the rotation axis of the rotating part 12; similarly, the second limiting part 232 can abut against both sides in the direction of the rotation axis of the second component 1122 to limit the movement of the locking member 1 in the axial direction of the rotation axis of the rotating part 12. With this configuration, through the cooperation of the first component 1121 and the first limiting part 231, and the cooperation of the second component 1122 and the second limiting part 232, the movement of the locking member 1 in the axial direction of the rotation axis of the rotating part 12 is limited, ensuring that the locking member 1 does not undergo axial displacement during the linear movement process in the first stage and the rotation process in the second stage, ensuring the stability of the movement of the locking member 1, and thus guaranteeing the locking effect of the locking member 1.

[0114] Implementation Method 3

[0115] This embodiment is a further improvement based on the first or second embodiment. The improvement lies in further defining the structure of the locking member 1 and the housing 2 to guide the movement of the locking member 1. Specifically, the rotating part 12 can cooperate with the guide member 24 of the housing 2 to guide the movement of the locking member 1.

[0116] Accordingly, such as Figure 3 As shown, the housing 2 also includes:

[0117] The guide component 24 is used to cooperate with the rotating part 12 to guide the movement of the locking member 1.

[0118] In this embodiment, the guide component 24, through its cooperation with the rotating part 12, guides the movement of the locking member 1, ensuring that the locking member 1 maintains a stable trajectory during movement and avoiding jamming or misalignment caused by unstable movement. This makes the movement of the locking member 1 more stable and smooth. Specifically, the guide component 24 can adopt a groove structure, in which the rotating part 12 slides, thereby guiding the movement trajectory of the locking member 1. It is worth mentioning that the rotating part 12 can be in the form of a cylinder. On the one hand, the cylinder can cooperate with the groove to guide the movement trajectory of the locking member 1; on the other hand, the cylinder can be used directly as the rotating part 12, and the cylinder can rotate without affecting its cooperation with the groove, satisfying the requirements of linear movement and rotational movement of the locking member 1.

[0119] In some embodiments, the limiting member 22 may be disposed within the guide member 24. For example, the limiting member 22 may be a detachable component, installed within the guide member 24 using methods such as snap-fits or screws. Furthermore, the guide member 24 may have multiple mounting positions such as slots and screw holes along its length for mounting the limiting member 22. By changing the mounting position of the limiting member 22, the travel distance of the locking member 1 is changed to adapt to different screens. In other embodiments, the limiting member 22 may be formed from at least a portion of the guide member 24. For example, as... Figure 3 As shown, the guide component 24 is a slide groove, and the limiting component 22 can be the side wall of one end of the slide groove in the length direction. That is, the moving distance of the rotating part 12 is directly limited by the length of the slide groove, and the side wall of one end of the slide groove abuts against the rotating part 12 to limit the movement of the rotating part 12.

[0120] In some preferred embodiments, such as Figure 3 As shown, the locking element 1 further includes:

[0121] The guide portion 13 and the rotating portion 12 are spaced apart along the pushing direction of the drive assembly 3;

[0122] The guide portion 13 is used to cooperate with the guide component 25 of the housing 2 to guide the movement of the locking member 1.

[0123] Accordingly, the housing 2 further includes:

[0124] The guide component 25 is used to cooperate with the guide part 13 to guide the movement of the locking member 1.

[0125] In this embodiment, by providing the guide part 13 and the guide component 25, and utilizing the cooperation between the guide part 13 and the guide component 25, the movement of the locking member 1 is guided, ensuring that the locking member 1 maintains a stable trajectory during movement and avoiding jamming or misalignment caused by unstable movement. This makes the movement of the locking member 1 more stable and smooth. Specifically, the guide component 25 can adopt a groove structure, in which the rotating part 12 slides, thereby guiding the movement trajectory of the locking member 1.

[0126] Furthermore, the guide part 13 and the rotating part 12 are spaced apart along the pushing direction of the drive assembly 3. The guide part 13 can cooperate with the guide component 25, while the rotating part 12 can cooperate with the guide component 24. The two complement each other and can better guide the movement of the locking member 1, ensuring that the locking member 1 maintains a stable trajectory during movement and avoiding jamming or misalignment caused by unstable movement, thereby making the movement of the locking member 1 more stable and smooth.

[0127] In some more preferred embodiments, such as Figure 3 As shown, the guide component 25 includes at least:

[0128] The straight segment 251 is used to guide the locking member 1 from the initial position to the rotational position;

[0129] Arc segment 252 is used to guide the rotation of the locking member 1.

[0130] Specifically, in this embodiment, the straight segment 251 and the arc segment 252 are sequentially arranged and connected to each other along the moving direction of the guide portion 13. Thus, when the drive assembly 3 pushes the locking member 1 to move, in the first stage, the guide portion 13 is located within the straight segment 251 and, guided by the straight segment 251, moves along the straight segment 251 to guide the locking member 1 from its initial position to its rotational position. In the second stage, since the rotational portion 12 abuts against the limiting portion, the drive assembly 3 continues to push the locking member 1 to move, and the locking member 1 rotates about the rotational portion 12 as its axis. Simultaneously, the guide portion 13 enters the arc segment 252 and, guided by the arc segment 252, moves along the arc segment 252 to guide the locking member 1 to rotate about the rotational portion 12 as its axis. Conversely, when it is necessary to release the locking rotation of the external mechanism (i.e., the screen), the drive assembly 3 pulls the locking member 1 to move, and the locking member 1 resets along the aforementioned path.

[0131] By configuring the straight segment 251 and the curved segment 252, the guide part 13 can cooperate with the straight segment 251 and the curved segment 252 in the first and second stages of the movement of the locking member 1, respectively, to guide the movement of the locking member 1. This ensures that the locking member 1 maintains a stable trajectory during movement, avoiding jamming or misalignment caused by unstable movement, thus making the movement of the locking member 1 more stable and smooth. Specifically, the guide part 25 can adopt a groove structure, in which the guide part 13 slides to guide the movement trajectory of the locking member 1.

[0132] Implementation Method 4

[0133] This embodiment is a further improvement based on the first, second, or third embodiment. The improvement lies in defining the specific shapes of the driving component 3 and the locking member 1 to meet the requirement of stable and controllable movement of the locking member 1. Specifically, as... Figure 5 and Figure 6 As shown, the locking element 1 further includes:

[0134] The connecting part 14 is used to connect to the drive component 3.

[0135] Accordingly, the driving component 3 includes:

[0136] Drive motor 31 provides driving power;

[0137] The drive block 32 is used to connect with the connecting part 14 of the locking member 1. The drive block 32 is connected to the drive motor 31 and can be driven by the drive motor 31 to move the locking member 1.

[0138] A slide rail 33 is disposed on the housing 2 and connected to the drive block 32 for guiding the drive block 32 to move.

[0139] In this embodiment, the drive motor 31 is connected to the connecting part 14 of the locking member 1 via the drive block 32. The drive block 32 moves under the guidance of the slide rail 33, thereby driving the locking member 1 to move. The drive motor 31 provides driving power, enabling the drive block 32 to move smoothly on the slide rail 33, ensuring that the locking member 1 can accurately reach the predetermined position. The slide rail 33 ensures the movement path of the drive block 32, making the entire driving process smoother and more accurate.

[0140] In this embodiment, by adopting a combination design of drive motor 31, drive block 32 and slide rail 33, the effect of precise control of the movement of locking component 1 can be achieved, which solves the problem that the locking component 1 cannot be accurately positioned due to structural or assembly problems in the prior art. It has higher reliability and stability, and can ensure that the vehicle-mounted ceiling TV will not produce abnormal noise due to shaking when it is closed.

[0141] It is worth mentioning that, in order to meet the requirements of linear and rotational movement of the locking member 1 connected to the drive assembly 3, the connecting part 14 can be pushed by the drive assembly 3 to drive the locking member 1 to move to the rotational position, and when the locking member 1 is in the rotational position and rotates, the connecting part 14 can move relative to the drive assembly 3.

[0142] Specifically, in some embodiments, such as Figure 5 As shown, the drive block 32 has a drive groove 321, the connecting part 14 is embedded in the drive groove 321, the drive groove 321 can abut against the connecting part 14 and push the locking member 1 to move, and the connecting part 14 can move along the drive groove 321 to accommodate the rotation of the locking member 1.

[0143] By providing a drive groove 321 in the drive block 32, relative movement can occur between the drive block 32 and the connecting part 14, thereby accommodating the rotation of the locking member 1. This design effectively solves the problem in the prior art where the locking member 1 cannot reach the expected position due to structural or assembly issues. Specifically, when the drive block 32 pushes the connecting part 14 to move, the connecting part 14 can move along the drive groove 321 to accommodate the positional changes of the locking member 1 during rotation, thereby ensuring that the locking member 1 can rotate smoothly and reach the expected position. Specifically, the shape of the drive groove 321 can be adapted to the movement path of the connecting block when it rotates around the pivot.

[0144] In another embodiment, it can be configured in the opposite manner, that is, the connecting part 14 has the driving groove 321, the driving block 32 is embedded in the driving groove 321, the driving block 32 can abut against the inner wall of the driving groove 321 and push the locking member 1 to move, and the driving block 32 can move within the driving groove 321 to accommodate the rotation of the locking member 1.

[0145] In some embodiments, such as Figure 5 As shown, the driving component 3 further includes:

[0146] A reduction gear set, the input end of which is connected to the drive motor 31;

[0147] The power transmission component 34 is connected to the drive block 32 and to the output end of the reduction gear set.

[0148] The reduction gear set of the drive assembly 3, connected to the drive motor 31, effectively reduces the motor speed and increases the output torque, thereby providing stronger driving force and ensuring the stability and reliability of the locking mechanism during operation. The power transmission component 34 is connected to the drive block 32 and to the output end of the reduction gear set, enabling it to transmit the reduced power to the drive block 32, driving the locking element 1 to move.

[0149] Specifically, the reduction gear set can employ a multi-stage gear reduction method, progressively reducing speed and increasing torque through the meshing of multiple gears. The input end of the reduction gear set is connected to the output shaft of the drive motor 31, and the output end is connected to the power transmission component 34, thereby realizing the transmission and conversion of power. The power transmission component 34 can adopt a gear, rack, or other transmission structure, connected to the drive block 32, driving the locking member 1 to move. For example, the reduction gear set can include a single-stage or multi-stage planetary gear set, achieving a wide range of reduction ratios and high torque output through the meshing of planetary gears. The power transmission component 34 can adopt a rack structure, meshing with the gears on the drive block 32, and driving the drive block 32 to move through the linear motion of the rack, realizing the rotation and locking operation of the locking member 1.

[0150] In this embodiment, by adding a reduction gear set to the drive assembly 3, the output torque of the drive motor 31 can be effectively improved, ensuring the stability and reliability of the electric locking mechanism in practical applications.

[0151] In some preferred embodiments, such as Figure 5 As shown, the drive block 32 is provided with a receiving groove 322, which extends along the moving direction of the drive block 32;

[0152] The power transmission component 34 includes:

[0153] Rack 341 is disposed within the receiving groove 322;

[0154] Gear 342 is connected to the output end of the reduction gear set. Gear 342 is located in the receiving groove 322 and matches the rack 341.

[0155] The smooth transmission of the power transmission component 34 is achieved through the receiving groove 322 on the drive block 32 and the rack 341 and gear 342 located within the receiving groove 322. Specifically, the output end of the reduction gear set matches the rack 341 through the gear 342, driving the rack 341 to move along the receiving groove 322, thereby pushing the drive block 32 to move in its direction of movement. This design can effectively transmit the output power of the reduction gear set to the drive block 32, ensuring the smooth movement of the drive block 32. In addition, since the rack 341 and gear 342 are both housed in the receiving groove 322 on the drive block 32, on the one hand, the size of the component can be effectively reduced, improving the compactness of the parts and facilitating the miniaturization of the electric locking mechanism; on the other hand, the rack 341 and gear 342 housed in the receiving groove 322 are protected by the drive block 32 from direct impacts from the outside, and can also be isolated in a relatively enclosed space, providing a stable working environment for the rack 341 and gear 342 and reducing the impact of external interference on the transmission system.

Although the present utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present utility model, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the scope of the technical solutions of the present utility model.
