Description

Technical Field

[0001] This utility model relates to the technical field of display screens, and more particularly to a locking structure and a display screen. Background Technology

[0002] Currently, the market share of new energy vehicles is gradually increasing, and more and more new energy vehicles are moving towards high-end models, with a growing emphasis on user experience. Some new energy vehicle manufacturers choose to install flip-up screens in the rear seats for rear passengers. To prevent the flip-up screen from opening due to vehicle vibrations when closed, a locking mechanism is typically installed to lock it in place.

[0003] In related technologies, the locking structure typically uses a motor to drive the locking mechanism to lock the flip screen. This method has a high cost due to the use of a motor, and the motor also occupies rear passenger space, which is detrimental to the interior layout of the car. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] The technical problem to be solved by this utility model is to provide a locking structure and display screen, which guides the sliding part through a slide groove, efficiently converting linear sliding into the rotational motion of the locking element; at the same time, the locking action is linked to the flipping action of the first housing, eliminating the need for an additional independent locking operation mechanism, saving space, simplifying the overall structure, and the locking and unlocking process is driven by the closing and unfolding action of the first housing itself, realizing an automated process of "closing is locking, unfolding is unlocking", which greatly improves the convenience and intuitiveness of user operation.

[0006] (II) Technical Solution

[0007] The solution adopted by this utility model to solve the above-mentioned technical problems is a locking structure, including a first shell that can be flipped and a second shell that is rotatably connected to the first shell;

[0008] The second housing is provided with two sliding grooves;

[0009] The first housing is symmetrically provided with two locking members, each of which is rotatably connected to the first housing through a pivot point;

[0010] Each of the locking members has a sliding part at one end, which is adapted to fit in the slide groove and can slide along the slide groove; and a locking part at the other end of each of the locking members.

[0011] The slide is configured such that when the sliding part is driven by an external force to slide from a first position to a second position within the slide, it can guide the two locking members to rotate around their respective rotation fulcrums, causing the two locking parts to move closer to each other so that the locking members are in a locked state; when the sliding part returns from the second position to the first position, it can guide the two locking members to rotate around their respective rotation fulcrums, causing the two locking parts to move away from each other so that the locking members are in an unlocked state.

[0012] In some embodiments, the rear end of the first housing and the rear end of the second housing are rotatably connected by a pivot pin; the slide groove is provided at the front end of the second housing; the first housing is provided with three downwardly extending, spaced-apart extension arms at one end near the second housing, and a rotating shaft passes through the three extension arms; the locking member is sleeved on the portion of the rotating shaft between the two extension arms near the front end; and the sliding part extends towards the front end relative to the locking member and extends into the slide groove, sliding along the slide groove under the drive of an external force.

[0013] By adopting the above solution, the sliding part is guided by the slide groove, which efficiently converts the linear sliding into the rotational motion of the locking element. At the same time, the locking action is linked to the flipping action of the first housing, eliminating the need for an additional independent locking mechanism, saving space, simplifying the overall structure, and the locking and unlocking process is driven by the closing and unfolding action of the first housing itself, realizing an automated process of "closing is locking, unfolding is unlocking", which greatly improves the convenience and intuitiveness of user operation.

[0014] In some embodiments, each of the slide grooves is provided with a continuous guide groove, the guide groove having a first locking position and a second locking position at its two ends, and an inclined or arc-shaped transition section connecting the first locking position and the second locking position; wherein the first locking position corresponds to a first position of the sliding part, and the second locking position corresponds to a second position of the sliding part.

[0015] By adopting the above scheme and setting the transition section, the locking member can be rotated around its respective rotation fulcrum, thereby realizing the unlocking and locking of the two sliding parts.

[0016] In some embodiments, the distance between the two first locking positions is smaller than the distance between the two second locking positions; during the sliding part sliding along the slide groove from the first locking position to the second locking position, it slides along the transition section, and the two sliding parts move towards each other. Since the locking member is rotated about its respective rotation fulcrum, the two locking parts move towards each other, thereby causing the two locking parts to release the vehicle display screen; while during the sliding part sliding along the slide groove from the second locking position to the first locking position, it slides along the transition section, and the two sliding parts move towards each other. Since the locking member is rotated about its respective rotation fulcrum, the two locking parts move towards each other, thereby causing the two locking parts to clamp the vehicle display screen.

[0017] In some embodiments, the first housing includes two symmetrically arranged slots, through which the locking part can extend out of the first housing; a first end is formed at one end of the two slots that are close to each other, and a second end is formed at one end that is far from each other; when the locking part abuts against the first end, the locking member is in a locked state; when the locking part abuts against the second end, the locking member is in an unlocked state.

[0018] By adopting the above solution, the first and second ends of the slot limit the rotation range of the locking component, providing a clear stopping sensation in both the locked and unlocked states, thus enhancing the user experience.

[0019] In some embodiments, a first elastic element is further included at the pivot point of the locking member and the first housing, the first elastic element being capable of providing a force to the locking member to a locking state.

[0020] In some embodiments, the first elastic element is a torsion spring, and the first elastic element is assembled on a portion of a rotating shaft between two extension arms near the rear end; wherein one end of the first elastic element acts on the rotating shaft, the other end acts on the locking element, and the first end is inserted into the lower end of the locking element.

[0021] By adopting the above scheme, during the process of the locking member returning from the unlocked state to the locked state, the elastic force of the first elastic member can assist the locking member to quickly and automatically reset, making the operation less strenuous and the action faster.

[0022] In some embodiments, the first housing is provided with a locking hook, and the second housing is provided with a locking fastener; or, the first housing is provided with a locking fastener, and the second housing is provided with a locking hook; when the locking hook is locked on the locking fastener, the first housing is in a closed state relative to the second housing; pressing the first housing can drive the locking hook to disengage from the locking fastener, so that the first housing can be flipped to an open state relative to the second housing; pressing the first housing can drive the locking hook to lock on the locking fastener, so that the first housing can be flipped to a closed state relative to the second housing.

[0023] By adopting the above solution, the cooperation between the locking hook and the locking buckle ensures that the first housing can be firmly locked in the closed state, avoiding accidental opening due to accidental contact or vibration; at the same time, locking and releasing can be achieved by "pressing" the first housing, making the operation intuitive and simple.

[0024] In some embodiments, a second elastic member is further provided between the first housing and the second housing, the second elastic member being capable of providing a force to the first housing to tend towards an extended state.

[0025] In some embodiments, two mounting seats are spaced apart on the second housing, and a second elastic element is assembled on each of the two mounting seats. The second elastic element is a torsion spring, one end of which acts on the first housing and the other end of which acts on the second housing.

[0026] By adopting the above solution, when the locking hook is released, the elastic force of the second elastic element can automatically push the first shell open to a certain angle, achieving the effect of "one-click automatic unfolding", which enhances the technological feel of the product and the user experience.

[0027] In some embodiments, a limiting member is provided on the first housing and a limiting groove is provided on the second housing; the limiting member is adapted to the limiting groove; and the limiting groove has a limiting portion at one end near the first housing, and when the first housing is flipped relative to the second housing until the limiting member abuts against the limiting portion, the first housing is in its maximum unfolded state.

[0028] In some embodiments, the limiting member is fixed to the first housing by screws.

[0029] By adopting the above solution, the maximum unfolding angle of the first housing is limited by the cooperation of the limiting component and the limiting groove, which can prevent the user from excessively flipping the first housing.

[0030] In some embodiments, a gear portion is provided on the first housing and a damper is provided on the second housing; or, a damper is provided on the first housing and a gear portion is provided on the second housing; the gear portion and the damper are meshed together.

[0031] By adopting the above scheme, the damper and gear unit work together to provide uniform resistance for the rotation of the first housing, making the rotation process of the first housing slow, stable and smooth.

[0032] The solution adopted by this utility model to solve the above-mentioned technical problems is a display screen, which is applied to automobiles. The display screen includes a screen and a locking structure as described above. The screen is magnetically connected to the first housing. When the locking member is in the locked state, it can clamp the screen. When the locking member is in the unlocked state, it can release the screen.

[0033] In some embodiments, the first housing is further provided with a plurality of heat dissipation holes, which help dissipate the heat generated when the screen is working in a timely manner, extend the lifespan of the screen, and ensure the stability of display performance.

[0034] Using the above solution, the screen is connected magnetically and fixed with a locking structure, which enables quick installation and removal of the screen, facilitating the replacement, repair or upgrade of the screen module.

[0061] The technical solutions provided by the various embodiments of this application are described below with reference to the accompanying drawings.

[0062] like Figures 1-9As shown, this utility model provides a locking structure, including a rotatable first housing 100 and a second housing 200 rotatably connected to the first housing 100; the second housing 200 is provided with two sliding grooves 201; the first housing 100 is symmetrically provided with two locking members 300, each of the locking members 300 being rotatably connected to the first housing 100 through a rotation fulcrum; one end of each locking member 300 is provided with a sliding part 301, which is adapted to the sliding groove 201 and can slide along the sliding groove 201; the other end of each locking member 300 is provided with... The sliding part 302 is provided; the sliding groove 201 is configured such that when the sliding part 301 is driven by an external force to slide from a first position to a second position within the sliding groove 201, it can guide the two locking members 300 to rotate around their respective rotation fulcrums, causing the two locking parts 302 to move closer to each other so that the locking members 300 are in a locked state; when the sliding part 301 returns from the second position to the first position, it can guide the two locking members 300 to rotate around their respective rotation fulcrums, causing the two locking parts 302 to move away from each other so that the locking members 300 are in an unlocked state. In some embodiments, the rear end of the first housing 100 and the rear end of the second housing 200 are rotatably connected by a pivot pin 700; the slide groove 201 is provided at the front end of the second housing 200; the first housing 100 is provided with three downwardly extending extension arms 105 arranged at intervals near the end of the second housing 200, and a rotating shaft 106 passes through the three extension arms 105; the locking member 300 is sleeved on the portion of the rotating shaft 106 between the two extension arms 105 near the front end; and the sliding part 301 extends towards the front end relative to the locking member 300 and extends into the slide groove 201, sliding along the slide groove 201 under the drive of an external force. By adopting the above solution, the sliding part 301 is guided by the slide groove 201, which efficiently converts the linear sliding into the rotational motion of the locking member 300. At the same time, the locking action is linked to the flipping action of the first housing 100, eliminating the need for an additional independent locking mechanism, saving space, simplifying the overall structure, and the locking and unlocking process is driven by the closing and unfolding action of the first housing 100 itself, realizing an automated process of "closing is locking, unfolding is unlocking", which greatly improves the convenience and intuitiveness of user operation.

[0063] In some embodiments, each of the slide grooves 201 has a continuous guide groove 2011. The guide groove 2011 has a first locking position 2011a and a second locking position 2011b at its two ends, and an inclined transition section 2011c connecting the first locking position 2011a and the second locking position 2011b. The first locking position 2011a corresponds to a first position of the sliding part 301, and the second locking position 2011b corresponds to a second position of the sliding part 301. Using the above scheme, the transition section 2011c allows the locking member 300 to rotate around its respective rotation fulcrum, thereby enabling the unlocking and locking of the two sliding parts 301. In some embodiments, the distance between the two first locking positions 2011a is smaller than the distance between the two second locking positions 2011b; during the sliding part 301 slides along the slide groove 201 from the first locking position 2011a to the second locking position 2011b, it slides along the transition section 2011c, and the two sliding parts 301 move towards each other. Since the locking member 300 is rotated about its respective rotation fulcrum, the two locking parts 302 move towards each other, thereby causing the two locking parts 302 to release the vehicle display screen; while during the sliding part 301 slides along the slide groove 201 from the second locking position 2011b to the first locking position 2011a, it slides along the transition section 2011c, and the two sliding parts 301 move towards each other. Since the locking member 300 is rotated about its respective rotation fulcrum, the two locking parts 302 move towards each other, thereby causing the two locking parts 302 to clamp the vehicle display screen. In some embodiments, the first housing 100 includes two symmetrically arranged slots 101 through which the locking part 302 can extend out of the first housing 100; a first end 1011 is formed at one end of the two slots 101 that are close to each other, and a second end 1012 is formed at one end that is far from each other; when the locking part 302 abuts against the first end 1011, the locking member 300 is in a locked state; when the locking part 302 abuts against the second end 1012, the locking member 300 is in an unlocked state. With the above solution, the first end 1011 and the second end 1012 of the slots 101 define the rotation range of the locking member 300, providing a clear stopping sensation in both the locked and unlocked states, thus enhancing the user experience. In some embodiments, a first elastic member 400 is also included, connected at the rotation fulcrum of the locking member 300 and the first housing 100, the first elastic member 400 providing a force to the locking member 300 that tends towards the locked state.In some embodiments, the first elastic element 400 is a torsion spring, and the first elastic element 400 is assembled on a portion of the rotating shaft 106 between the two extension arms 105 near the rear end; wherein one end of the first elastic element 400 acts on the rotating shaft 106, and the other end acts on the locking member 300, and the other end is inserted into the lower end of the locking member 300. Using the above scheme, during the process of the locking member 300 returning from the unlocked state to the locked state, the elastic force of the first elastic element 400 can assist the locking member 300 to quickly and automatically reset, making the operation less strenuous and the action faster.

[0064] In some embodiments, the first housing 100 is provided with a locking hook 102, and the second housing 200 is provided with a locking fastener 202. When the locking hook 102 is locked onto the locking fastener 202, the first housing 100 is in a closed state relative to the second housing 200. Pressing the first housing 100 can drive the locking hook 102 to disengage from the locking fastener 202, so that the first housing 100 can be flipped to an unfolded state relative to the second housing 200. Pressing the first housing 100 can also drive the locking hook 102 to lock onto the locking fastener 202, so that the first housing 100 can be flipped to a closed state relative to the second housing 200. Using the above solution, the cooperation between the locking hook 102 and the locking fastener 202 ensures that the first housing 100 can be securely locked in the closed state, preventing accidental unfolding due to accidental contact or vibration. Simultaneously, locking and releasing can be achieved simply by "pressing" the first housing 100, making the operation intuitive and simple. In some embodiments, a second elastic element 500 is further included, disposed between the first housing 100 and the second housing 200. The second elastic element 500 provides a force to the first housing 100 that tends to unfold. In some embodiments, two mounting seats are spaced apart on the second housing 200, and a second elastic element 500 is assembled on each of the two mounting seats. The second elastic element 500 is a torsion spring, with one end acting on the first housing 100 and the other end acting on the second housing 200. Using the above solution, when the locking hook 102 is released, the elastic force of the second elastic element 500 can automatically spring the first housing 100 open to a certain angle, achieving the effect of "one-click automatic unfolding," enhancing the product's technological feel and user experience.

[0065] In some embodiments, a limiting member 103 is provided on the first housing 100, and a limiting groove 203 is provided on the second housing 200; the limiting member 103 is adapted to be within the limiting groove 203; and the limiting groove 203 has a limiting portion at one end near the first housing 100, so that when the first housing 100 is flipped relative to the second housing 200 until the limiting member 103 abuts against the limiting portion, the first housing 100 is in its maximum unfolded state. In some embodiments, the limiting member 103 is fixed to the first housing 100 by screws 107. By adopting the above solution, the maximum unfolding angle of the first housing 100 is limited by the cooperation of the limiting member 103 and the limiting groove 203, which can prevent the user from excessively flipping the first housing 100.

[0066] In some embodiments, a gear portion 104 is provided on the first housing 100, and a damper 204 is provided on the second housing 200; the gear portion 104 and the damper 204 are meshed together. Using the above scheme, the cooperation between the damper 204 and the gear portion 104 provides uniform resistance for the rotation of the first housing 100, making the rotation process of the first housing 100 slow, stable, and smooth.

[0067] like Figures 1-9 As shown, this utility model provides a display screen applied to an automobile. The display screen includes a screen 600 and a locking structure as described above. The screen 600 is magnetically connected to the first housing 100. When the locking member 300 is in the locked state, it can clamp the screen 600; when the locking member 300 is in the unlocked state, it can release the screen 600. In some embodiments, the first housing 100 is also provided with a plurality of heat dissipation holes 108, which helps to dissipate the heat generated by the screen 600 during operation, extending the service life of the screen 600 and ensuring stable display performance. Using the above solution, the screen 600 is connected magnetically and fixed by the locking structure, realizing quick installation and removal of the screen 600, facilitating replacement, repair, or upgrade of the screen 600.
