Abstract
Description
Technical Field
[0001] The present disclosure relates to the field of vehicle-mounted electronics, and in particular to an electric lock tongue structure for a vehicle-mounted ceiling-mounted television. Background Art
[0002] A car ceiling TV is an electronic device mounted on the vehicle's roof that flips downward when in use and folds upward when not in use. To protect both the TV and the passengers, the screen needs to be locked after folding upward. Existing car ceiling TVs typically lock with a retractable latch. However, to increase user convenience, a motor and gear-driven latch can be installed, allowing users to unlock and lock the screen with a simple, effortless operation, such as pressing a switch.
[0003] Through extensive research and practice, the inventors discovered that existing electric lock tongue devices usually place the gears and lock tongues directly in the same space, resulting in the lubricant used to lubricate the gears being: transferred to many structural surfaces that do not require lubrication, lost outside the lock tongue device as the lock tongue expands and contracts, and introduced contaminants as the lock tongue expands and contracts; and the above situations are difficult to circumvent by controlling the amount of lubricant added. If the amount of lubricant added is small, the lubrication expectation cannot be achieved, affecting the service life of the lock tongue; if the amount of lubricant added is large, it may increase costs and may also contaminate the vehicle interior, affecting the user experience. Utility Model Content
[0004] Based on this, the present invention aims to provide an electric lock bolt structure for a car-mounted ceiling-mounted TV. By providing a partition to separate the motor, gears, rack, and other structures, the lubricant can be limited to the motor, gears, and other parts that require lubrication as much as possible. This helps to improve the effectiveness of the added lubricant, slow the rate of lubricant spillage, and maintain the desired lubrication effect over a long period of time. It has the advantages of long-term lubrication and a long service life.
[0005] A motorized lock tongue structure for a vehicle-mounted ceiling-mounted TV comprises a shell and a partition, wherein the shell comprises a shell and a cover body arranged at the top end of the shell, the partition body is located inside the shell, and the two sides of the partition are respectively arranged toward the cover body and the bottom of the shell; a motor and a driving gear driven to rotate by the motor are provided between the partition and the bottom of the shell, the driving gear passes through the partition, a rack is provided between the partition and the cover body, and a lock tongue and a limit bar extending in the same direction as the rack are provided, the top of the rack is meshed with the driving gear, the bottom of the rack is slidably engaged with the limit bar, the lock tongue passes through the shell in its movement direction, and the limit bar is fixed to the shell.
[0006] The electric lock bolt structure for a vehicle-mounted ceiling-mounted TV disclosed herein utilizes a partition to separate the motor, gears, and rack components. This allows lubricants to be confined to the motor, gears, and other areas requiring lubrication. This improves the effectiveness of the added lubricant, slows down its spillage, and maintains the desired lubrication effect over time. This provides the advantages of long-lasting lubrication and a long service life.
[0007] Furthermore, a guide bar extending in the same direction as the rack is included, the guide bar being fixed to the bottom of the rack and slidably abutting against the limit bar. The provision of the guide bar increases the stability of the path of the lock tongue during its telescopic sliding, effectively preventing unexpected wear between the lock tongue and the lock tongue base of the ceiling-mounted TV.
[0008] Furthermore, the device further includes a first stopper located between the cover plate and the partition plate. The first stopper is fixed to the rack and abuts against the housing when the lock tongue engages with the lock tongue receptacle of the vehicle-mounted ceiling-mounted television. The first stopper limits the extension length of the lock tongue, thereby preventing the extension length of the lock tongue from exceeding the depth of the lock tongue seat, thereby preventing excessive wear and even damage to the motor, gear, lock tongue, and lock tongue seat.
[0009] Furthermore, the invention further comprises a limit block and a second limit portion, both of which are located between the cover plate and the partition plate, the limit block being fixed to the partition plate, and the second limit portion being fixed to the rack, so that when the lock tongue is retracted into the housing, the second limit portion abuts against the limit block. Providing the limit block and the second limit portion to limit the retraction of the lock tongue is beneficial for controlling the length of the lock tongue and reducing the material cost of the lock tongue. On the other hand, it is beneficial for preventing the lock tongue from retracting excessively, thereby preventing additional wear and even damage to the motor, gear, lock tongue, and housing.
[0010] Furthermore, the device further includes a slide rail extending in the same direction as the rack, and a sliding portion. The slide rail and the sliding portion are both located between the cover plate and the partition plate. The slide rail is fixed to the housing, and the sliding portion is fixed to the rack. The sliding portion is provided with a slide groove that slidably engages with the slide rail. The provision of the slide rail and the sliding portion increases the stability of the path of the lock tongue during telescopic sliding, effectively preventing unexpected wear between the lock tongue and the lock tongue base of the ceiling-mounted TV.
[0011] Furthermore, the device further includes a first buffer portion, which is located between the first limiting portion and the housing. The first buffer portion is detachably fixed to the housing. When the locking tongue engages with the locking tongue socket of the vehicle-mounted ceiling-mounted TV, the first limiting portion abuts against the first buffer portion. The provision of the first buffer portion provides a buffer when the first limiting portion is about to abut the housing, effectively reducing losses and noise.
[0012] Furthermore, a second buffer is provided between the stop block and the second stop portion. The second buffer is detachably fixed to the stop block. When the lock tongue is retracted into the housing, the second stop portion abuts against the second buffer. The second buffer provides a buffer when the second stop portion is about to abut the stop block, effectively reducing losses and noise.
[0013] Furthermore, it also includes a worm gear and a transmission gear. The turbine is sleeved on the rotating shaft of the motor, and the transmission gear is meshed with the turbine and the driving gear.
[0014] Furthermore, it further includes a first fixing column, which is fixed to the bottom of the shell, and the top of the first fixing column abuts against the partition and is detachably fixed.
[0015] Furthermore, it also includes a first positioning column, which is fixed on the top of the first fixing column. The partition is provided with a positioning hole, the position of the positioning hole corresponds to the position of the positioning column, and the positioning column cooperates with the positioning hole.
[0016] The beneficial effects of this application are:
[0017] 1. By setting up partitions, the motor and gears are separated from the rack and other structures, so that the lubricating material can be limited to the parts that need lubrication, such as the motor and gears, as much as possible. This is beneficial to improve the effectiveness of the added lubricant, slow down the overflow rate of the lubricant, and maintain the expected lubrication effect for a long time.
[0018] 2. The guide strip is provided to increase the stability of the path of the lock tongue when it is telescopically sliding, thereby effectively avoiding unexpected wear between the lock tongue and the lock tongue base of the ceiling-mounted TV.
[0019] 3. By setting the first limit portion to limit the extended length of the lock tongue, it is prevented that the extended length of the lock tongue is greater than the depth of the lock tongue seat, thereby avoiding additional loss or even damage to the motor, gear, lock tongue, and lock tongue seat.
[0020] 4. By setting the limit block and the second limit part to limit the retraction of the lock tongue, on the one hand, it is beneficial to control the length of the lock tongue and reduce the material cost of the lock tongue. On the other hand, it is beneficial to avoid excessive retraction of the lock tongue, thereby avoiding additional loss or even damage to the motor, gear, lock tongue, and housing.
[0021] 5. By setting the slide rail and the sliding part, the stability of the path of the lock tongue when it is telescopically sliding is increased, effectively avoiding unexpected wear and tear between the lock tongue and the lock tongue base of the ceiling TV.
[0022] 6. By providing the first buffer portion, a buffer is provided when the first limiting portion is about to abut against the housing, thereby effectively reducing loss and noise.
[0023] 7. By providing the second buffer portion, buffering is performed when the second limiting portion is about to abut against the limiting block, thereby effectively reducing loss and noise.

[0044] Existing car ceiling TVs are usually locked by a retractable lock tongue. In order to increase the convenience of use for customers, a motor and gear are set to drive the extension and retraction of the lock tongue, so that customers can unlock and lock the ceiling screen through simple and labor-saving operations, such as pressing a switch.
[0045] Existing electric deadbolt devices usually place the gears and the lock tongue directly in the same space, resulting in the lubricant used to lubricate the gears being transferred to many structural surfaces that do not require lubrication, flowing out of the lock tongue device as the lock tongue expands and contracts, and introducing contaminants as the lock tongue expands and contracts. The above situations are difficult to avoid by controlling the amount of lubricant added. If the amount of lubricant added is small, the lubrication expectation cannot be achieved, affecting the service life of the lock tongue. If the amount of lubricant added is large, it may not only increase costs but also contaminate the vehicle interior and affect the user experience.
[0046] Based on this, the purpose of the present disclosure is to provide an electric lock tongue structure for a car-mounted ceiling TV. By setting a partition, the motor and gears and rack and other structures are separated, so that the lubricating material can be limited as much as possible to the parts that need lubrication, such as the motor and gears, which is beneficial to improve the effectiveness of the added lubricating oil, slow down the overflow rate of the lubricating oil, and maintain the expected lubrication effect for a long time.
[0047] The present disclosure discloses an electric lock tongue structure for a car-mounted ceiling TV. Figures 1 to 3, including a shell and a partition 2, the shell includes a shell 101 and a cover 102 covered on the top of the shell 101, the cover 102 and the top of the shell 101 are detachably fixed by screws, the partition 2 is located in the shell and fixed to the shell 101, and the two sides of the partition 2 are respectively arranged toward the cover 102 and the bottom of the shell 101; a motor 3 and a driving gear 4 driven by the motor 3 are provided between the partition 2 and the bottom of the shell 101, and the motor 3 is respectively provided at the bottom of the shell 101 and the partition 2 is provided toward the shell 101 The U-shaped motor 3 seat on one side of the bottom is arranged between the bottom of the shell 101 and the partition 2, and the driving gear 4 is arranged through the partition 2 and is connected to the motor 3. A worm gear 5 is sleeved on the rotating shaft of the motor 3 in this embodiment, and the worm gear 5 meshes with the transmission gear 6, and the transmission gear 6 meshes with the driving gear 4. When the motor 3 is running, the rotating shaft of the motor 3 rotates and drives the worm gear 5 to rotate, the turbine drives the transmission gear 6 to rotate, and the transmission gear 6 drives the driving gear 4 to rotate, thereby realizing the rotation of the driving gear 4 driven by the motor 3. In the embodiment, the driving gear 4 can also directly mesh with the worm gear 5 provided on the rotating shaft of the motor 3; a rack 7, a lock tongue 8 in the same extending direction as the rack 7, and two limit bars 9 in the same extending direction as the rack 7 are provided between the partition 2 and the cover body 102. The top of the rack 7 is provided with teeth and meshes with the driving gear 4. The bottom of the rack 7 is a plane and is slidably abutted against the two limit bars 9. One end of the lock tongue 8 is fixed to one end of the rack 7 and is integrated. Under the action of the limit bar 9, the driving gear 4 drives the rack 7 when it rotates. It slides in its extension direction, thereby driving the lock tongue 8 to slide. The lock tongue 8 is arranged through the shell in its movement direction. Specifically, under the action of the driving gear 4, the lock tongue 8 can extend out of the shell or retract into the shell. Among the two limit bars 9 of this embodiment, one limit bar 9 is fixed to the cover body 102 and integrated, and the other limit bar 9 is fixed to the partition 2 and fixed to the shell 101 through the partition 2. After the cover body 102 and the partition 2 are installed, the positions of the two limit bars 9 correspond to each other and both are slidably abutted against the bottom of the rack 7. An electric lock tongue structure of a car-mounted ceiling TV in an embodiment of the present disclosure is installed on the car-mounted ceiling TV, and a lock tongue base is provided in the direction in which the lock tongue 8 extends. When the lock tongue 8 extends into the lock tongue base, the car-mounted ceiling TV is locked, and the screen of the car-mounted ceiling TV cannot be bent downward. During use, after the car-mounted ceiling TV is folded upward, the rotation of the motor 3 can be controlled to make the lock tongue 8 extend out of the outer shell and into the lock tongue base, thereby locking the car-mounted ceiling TV. When unlocking is required, the rotation of the motor 3 can be controlled to make the lock tongue 8 retract into the outer shell, and the lock tongue 8 is pulled out from the lock tongue base, thereby unlocking the locked state of the car-mounted ceiling TV.The electric lock tongue structure of a vehicle-mounted ceiling-mounted TV in the embodiment of the present disclosure separates the motor 3 and structures such as the gear and rack 7 by providing a partition 2, so that the lubricating material can be limited as much as possible to the parts that need lubrication, such as the motor 3 and the gear. This is beneficial to improving the effectiveness of the added lubricating oil, slowing down the overflow rate of the lubricating oil, and maintaining the expected lubricating effect for a long time. It has the advantages of long-term lubrication and long service life.
[0048] In order to further ensure the service life of the lock tongue structure, in one embodiment, please refer to Figure 4 The electric lock tongue structure of the vehicle-mounted ceiling TV also includes a guide bar 10 extending in the same direction as the rack 7. The guide bar 10 is fixed to the bottom of the rack 7 and located between the two limit bars 9. The guide bar 10 also slidably abuts the two limit bars 9. Specifically, it can be considered that after the cover 102 and the partition 2 are installed, the guide bar 10 slides in the sliding groove formed by the gap between the two limit bars 9. The provision of the guide bar 10 increases the stability of the path of the lock tongue 8 during its telescopic sliding, effectively preventing unexpected wear between the lock tongue 8 and the base of the ceiling TV lock tongue 8.
[0049] In order to further ensure the service life of the lock tongue structure, in one embodiment, please refer to Figure 5 The electric lock tongue structure of the car-mounted ceiling TV also includes a first limiting portion 11.
