[0002] As an indispensable means of transportation in our lives, vehicles are widely used in people's lives to meet people's needs for convenient, fast and efficient travel. More and more people use tablet electronic devices to watch videos, listen to music or play games while driving to improve the entertainment of driving.

[0003] The Chinese utility model patent with announcement number CN220096264U discloses a support frame, a bearing member and a seat assembly. In the reference patent, the seat assembly includes a seat, a mounting interface provided on the seat, and a support frame that is plugged into the mounting interface. A tablet electronic device is mounted on the support frame, and users in the rear seats can use the tablet electronic device. The mounting interface includes a mounting member, a stopper, a protective member, a third rotating shaft, and a second reset elastic member. The protective member is used to cover the plug-in slot for the support frame to be plugged in, and the protective member is rotatably mounted on the stopper via the third rotating shaft. The support frame is inserted into the mounting interface so that the protective member flips upward toward the inside of the seat. When the support frame is removed from the mounting interface, the protective member automatically resets under the action of the second reset elastic member and covers the plug-in slot again.

[0004] With regard to the above-mentioned related technologies, although the protective member covers the plug-in slot through the second reset elastic member, the protective member itself is not locked. There is still a possibility that the rear-seat user may accidentally touch the protective member, causing the protective member to be manually opened, resulting in the possibility of damage to the circuit in the installation interface or entry of dust. Summary of the invention

[0005] In order to reduce the probability of the protective member being accidentally opened and improve the safety of the installation interface, the present application provides a button-free unlocking device.

[0006] The present application provides a button-free unlocking device that adopts the following technical solution: A buttonless unlocking device comprises a support frame for mounting a tablet electronic device and a mounting interface arranged on the back of a seat, the mounting interface comprising a mounting shell, a protective member rotatably mounted on the mounting shell, and a first elastic member for driving the protective member to reset, and also comprises a locking assembly for locking the protective member, the locking assembly comprising a locking frame rotatably mounted on the mounting interface, a first magnetic sheet arranged on the locking frame, a locking member slidably mounted on the mounting interface and abutting against the locking frame, and a second elastic member for driving the locking frame to reset, the inner side of the mounting shell has a locking groove for the locking member to slide; the support frame is provided with a second magnetic sheet magnetically attracted to the first magnetic sheet, when the second magnetic sheet approaches the first magnetic sheet, the first magnetic sheet drives the locking frame to rotate, the locking frame drives the locking member to slide out of the locking groove, and the protective member is unlocked from the locked state.

[0007] By adopting the above technical scheme, the setting of the locking component can lock the protective element, reducing the probability of the internal space of the installation interface being connected to the outside world due to the protective element being accidentally touched by the rear-seat user of the vehicle, and improving the safety performance and dustproof effect of the installation interface. When the support frame needs to be installed, the locking element is automatically disengaged from the locking groove through the cooperation of the first magnetic sheet and the second magnetic sheet, and the protective element is released from the locked state, and the support frame can be directly inserted into the installation interface. The unlocking of the protective element and the insertion of the support frame are carried out simultaneously, which is convenient to operate and has high unlocking efficiency. When the support frame is detached from the installation interface, the locking frame can automatically reset under the action of the second elastic member, so that the protective element is locked again.

[0008] Optionally, the locking member includes a locking portion for inserting into the locking groove and a driving portion cooperating with the locking frame, the driving portion is provided with a first driving inclined surface, and the locking frame has a second driving inclined surface abutting against the first driving inclined surface.

[0009] By adopting the above technical scheme, a matching method of the locking member and the locking frame is disclosed. The locking member includes a locking part and a driving part. Through the insertion of the locking part and the locking groove, the rotation of the protective member can be limited, thereby realizing the locking of the protective member. When the locking frame rotates, the first driving inclined surface of the driving part and the second driving inclined surface of the locking frame cooperate to convert the rotational motion into vertical motion, thereby realizing the sliding motion of the entire locking member, simplifying the mechanism design and saving space.

[0010] Optionally, the second elastic member includes a first wire spring and a second wire spring, the first wire spring drives the locking member to have a tendency to move toward the locking groove, the driving portion is provided with a first wire groove for arranging the first wire spring at the end away from the second driving inclined surface, and the protective member is provided with second wire grooves for arranging both ends of the wire spring member.

[0011] By adopting the above technical solution, the structural composition of the second elastic member is disclosed, the two ends of the first wire spring are respectively arranged in the second wire groove of the protective member, and the part between the two ends is arranged in the first wire groove. When the support frame is inserted into the installation interface, the locking member disengages from the locking groove, and the first wire spring is lifted and bent by the locking member. After the support frame is removed from the installation interface, the first wire spring is not subjected to external pressure and recovers its deformation, thereby pressing the locking member back into the locking groove.

[0012] Optionally, the second wire spring drives the locking frame to rotate away from the protective member, the protective member is provided with a third wire groove for arranging two ends of the second wire spring, and the locking frame has a fourth wire groove for arranging two ends of the second wire spring.

[0013] By adopting the above technical solution, the second wire spring is used for rotational reset of the locking frame. When the support frame is detached from the mounting interface, the external pressure on the second wire spring is released, and the second wire spring recovers its deformation, driving the locking frame to rotate away from the protective member. The locking member is reinserted into the locking groove under the action of the first wire spring.

[0014] Optionally, the protective member is provided with a first limiting sliding groove for the locking member to slide, and the first limiting sliding groove is located on a side of the protective member away from the first elastic member.

[0015] By adopting the above technical solution, the provision of the first limiting sliding groove can play a limiting and guiding role in the sliding of the locking member, thereby improving the stability of the locking member during sliding.

[0016] Optionally, the mounting interface is further provided with a limit frame body for limiting the rotation angle of the locking frame, the limit frame body and the protective member are fixedly connected, the limit frame body has a positioning surface for the locking frame to abut against, and when the locking frame abuts against the positioning surface, the protective member is in a locked state.

[0017] By adopting the above technical solution, the setting of the limit frame can limit the rotation angle of the locking frame, so that when the second elastic member recovers its deformation, it can reduce the situation where the locking frame rotates too much and the attraction and cooperation between the second magnetic sheet and the first magnetic sheet is weakened.

[0018] Optionally, the device includes two groups of locking assemblies, and the two groups of locking assemblies are symmetrically arranged along the central axis of the length direction of the protective member. The mounting shell is provided with two groups of rotating seats for rotatably mounting the two groups of locking assemblies respectively. The rotating seat is provided with a first rotating shaft, and the locking assembly is provided with a transmission member on the first rotating shaft, so that the synchronous rotation of the two groups of locking assemblies is realized through the transmission member.

[0019] By adopting the above technical solution, the setting of two groups of symmetrical locking components can achieve a more ideal locking effect on the protective member, further reducing the probability of the protective member being accidentally opened. The setting of the transmission member enables the two groups of locking components to move synchronously, thereby improving the unlocking efficiency of the locking components.

[0020] Optionally, the transmission member includes a first transmission gear disposed on one of the first rotating shafts and a second transmission gear disposed on the other first rotating shaft, and the first transmission gear and the second transmission gear are meshed with each other.

[0021] By adopting the above technical solution, the structural composition of the transmission member is disclosed, and the meshing cooperation of the first transmission gear and the second transmission gear enables that when the locking frame of one group rotates, the locking frame of the other group is driven to rotate synchronously, thereby realizing the unlocking and locking synchronization of the two groups of locking components.

[0022] Optionally, the locking frame is provided with a first installation slot for installing the first magnetic sheet, and the locking frame is provided with a limit block for limiting the detachment of the first magnetic sheet and a guide bevel block for guiding the installation of the first magnetic sheet on the opening end surface of the first installation slot.

[0023] By adopting the above technical solution, a method for installing the first magnetic sheet is disclosed. The first magnetic sheet is inserted into the first installation groove along the guide bevel block, and then the first magnetic sheet is completely pressed into the first installation groove manually or by equipment. By setting a limit stop block, the probability of the limit stop block detaching from the first installation groove can be reduced.

[0024] Optionally, the support frame includes a support frame body, a protective shell plugged into the support frame body, and the second magnetic sheet, and a second mounting groove for mounting the second magnetic sheet is provided at an end of the support frame body.

[0025] By adopting the above technical solution, the structural composition of the support frame is disclosed, the second magnetic sheet is fixedly inserted into the second installation groove, and then the protective shell is inserted into the support frame, and the second magnetic sheet is protected and fixed by the protective shell.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: The present application can lock the protective element by setting a locking component, thereby reducing the possibility that the internal space of the installation interface is connected to the outside world due to the user in the rear seat of the vehicle accidentally touching the protective element, thereby improving the safety and dustproof effect of the installation interface. The present application simplifies the unlocking operation by cooperating with the first magnetic sheet and the second magnetic sheet, thereby reducing the probability of accidental opening. The present application makes the locking effect of the protective member more ideal by setting up two groups of locking components and transmission parts. At the same time, when one group of locking components switches state, the other group of locking components is driven to switch synchronously through the transmission parts, thereby improving reliability and stability.

[0039] The following is combined with Figure 1-10 This application is described in further detail.

[0040] The embodiment of the present application discloses a button-less unlocking device.

[0041] Reference Figure 1 The button-less unlocking device is used for vehicle seats and tablet electronic device installation, including a support frame 1 for installing the tablet electronic device and a mounting interface 2 installed on the back of the seat.

[0042] Reference Figure 2 The mounting interface 2 includes a mounting housing 3, a protective member 4 rotatably mounted on the mounting housing 3, a first elastic member 5 for resetting the protective member 4, and a locking assembly 6 for locking the protective member 4. The mounting housing 3 includes a housing seat 31 for fixed connection with the seat, a decorative strip 32 plugged and fixed to the housing seat 31, an outer cover 33 disposed on the outer end surface of the decorative strip 32, and a limit frame 34 covering the locking assembly 6. The housing seat 31 and the seat are fixed by bolts or the like, and the outer cover 33 and the decorative strip 32 are plugged and fixed.

[0043] Combination Figure 3 The decorative strip 32 has a plug-in slot 321 that penetrates both side surfaces and is inserted into the support frame 1. The protective member 4 is rotatably mounted on the decorative strip 32 and seals the plug-in slot 321. The end surface of the protective member 4 exposed outside the seat is defined as the outer side, and the position of the plug-in slot 321 is defined as the inner side.

[0044] The protective member 4 is in the shape of a rectangular plate with arc portions at both ends, and its outer end surface is flush with the surface of the outer cover 33. The edge of the outer end surface of the protective member 4 also has a pressing annular surface 41 for the outer cover 33 to press, so that the protective member 4 will not rotate outward and improve the overall aesthetics.

[0045] Reference Figure 3 and Figure 4 The locking assembly 6 includes a locking frame 61 rotatably mounted on the protective member 4, a first magnetic sheet 62 limitedly mounted on the locking frame 61, a locking member 63 slidably mounted on the mounting interface 2 and abutting against the locking frame 61, and a second elastic member 64 driving the locking frame 61 to reset. In this embodiment, the mounting interface 2 is provided with two sets of locking assemblies 6, and the two sets of locking assemblies 6 are symmetrically arranged along the central axis of the protective member 4.

[0046] The protection member 4 has a rotating seat 42 for rotatably mounting two sets of locking assemblies 6, and a first rotating shaft 43 is rotatably mounted on the rotating seat 42. The rotation axis of the first rotating shaft 43 is perpendicular to the rotation axis of the protection member 4. The rotating seat 42 is located at the central axis of the protection member 4, and the locking assembly 6 is fixed with a transmission member 65 on the first rotating shaft 43, and the synchronous rotation of the two sets of locking assemblies 6 is achieved through the transmission member 65. The transmission member 65 includes a first transmission gear 651 fixed to one of the first rotating shafts 43 and a second transmission gear 652 fixed to the other first rotating shaft 43, and both transmission gears are gears with only half a gear ring.

[0047] Reference Figure 6, the first magnetic sheet 62 is a circular magnetic sheet. The locking frame 61 has a first mounting groove 611 for limiting the installation of the first magnetic sheet 62 on the side away from the first rotating shaft 43, and the locking frame 61 is integrally provided with a limit stopper 612 and a guide bevel 613 at the notch of the first mounting groove 611. The limit stopper 612 and the guide bevel 613 are symmetrically arranged along the axis of the first mounting groove 611, the limit stopper 612 has a limit stopper surface 6121, and the guide bevel 613 has a guide bevel 6131, and the limit stopper surface and the guide bevel 6131 have the same inclination direction. When installing, the assembler inserts the first magnetic sheet 62 obliquely from one side of the guide bevel 613, and then completely installs the first magnetic sheet 62 into the first mounting groove 611 by pressing.

[0048] Reference Figure 6 and Figure 7 The locking member 63 is slidably mounted on the decorative strip 32, and the sliding direction of the locking member 63 is parallel to the first rotating shaft 43. The decorative strip 32 is provided with a locking groove 322 for inserting the locking member 63 on the inner wall of the insertion groove 321. The locking member 63 includes a locking portion 631 and a driving portion 632.

[0049] The locking part 631 and the driving part 632 are integrally arranged, and the protective member 4 has a first limiting sliding groove 44 for limiting the sliding movement of the locking part 631, and the end of the locking part 631 also has a guide surface (not marked in the figure) for guiding the insertion into the locking groove 322. The driving part 632 is located on the side of the locking part 631 away from the protective member 4. The driving part 632 has a first driving inclined surface 6321 at the end facing the locking groove 322. The locking frame 61 has a clearance groove 614 corresponding to the locking member 63, and the locking frame 61 has a second driving inclined surface 6141 on the inner wall of the clearance groove 614 that abuts and cooperates with the first driving inclined surface 6321.

[0050] according to Figure 4 and Figure 7 The protective member 4 has two states of locking and unlocking through the cooperation of the locking frame 61 and the locking member 63: when the locking portion 631 is located in the locking groove 322, the protective member 4 is in the locked state ( Figure 4 ), at this time, the first driving inclined surface 6321 and the second driving inclined surface 6141 abut against each other, and there is a rotation gap between the locking frame 61 and the inner side surface of the protective member 4; when the lock is disengaged from the locking groove 322, the protective member 4 is in the unlocked state ( Figure 7 ), at this time, the first driving inclined surface 6321 and the second driving inclined surface 6141 are separated, and the locking frame 61 and the inner side surface of the protective member 4 are in contact.

[0051] The unlocking of the protective member 4 is achieved through the principle of magnetic attraction. A second magnetic sheet 11 that is attracted to the first magnetic sheet 62 is installed at the end of the support frame 1. When the support frame 1 is close to the outer side of the protective member 4, the first magnetic sheet 62 drives the locking frame 61 to rotate toward the protective member 4 under the action of the second magnetic sheet 11, so that the second driving inclined surface 6141 and the first driving inclined surface 6321 abut against each other, so that the locking member 63 disengages from the locking groove 322.

[0052] Reference Figure 8 The support frame 1 includes a support frame body 12 and a protective shell 13 sleeved on the support frame body 12. The end of the support frame body 12 has two second mounting grooves 121 for mounting the second magnetic sheet 11. The two second mounting grooves 121 correspond to the first mounting grooves 611 of the two sets of locking components 6. The protective shell 13 and the support frame body 12 are fixed by snapping.

[0053] Reference Figure 7 and Fig. 9 The second elastic member 64 is used to re-lock the locking assembly 6 after the support frame 1 is detached, and the two sets of locking assemblies 6 share the second elastic member. The second elastic member 64 includes a first wire spring 641 and a second wire spring 642. The first wire spring 641 is used to reset the locking member 63, and the second wire spring 642 is used to reset the locking member 63. The first wire spring 641 and the second wire spring 642 have the same structure, and both include two ends and a spring body.

[0054] The first wire spring 641 is arranged along the length direction of the protective member 4. The side of the driving part 632 away from the locking groove 322 has a first wire groove 6322 for arranging the spring body of the first wire spring 641. The protective member 4 is provided with a second wire groove 45 for arranging the two ends of the first wire spring 641 on one side of the first limiting sliding groove 44. The opening directions of the first wire groove 6322 and the second wire groove 45 are opposite, and the opening of the second wire groove 45 faces the locking groove 322. The first wire spring 641 provides the locking member 63 with an elastic force for sliding and resetting. When the first wire spring 641 is in a normal state, the protective member 4 is in a locked state, and the locking part 631 and the locking groove 322 are plugged and matched. When the protective member 4 is in an unlocked state, the locking part 631 is disengaged from the locking groove 322, and the first wire spring 641 is bent and deformed in a direction away from the locking groove 322 under the action of the locking member 63.

[0055] The second wire spring 642 is arranged along the length direction of the protective member 4. The protective member 4 is integrally provided with a limit seat 46 between the two rotating seats 42. The limit seat 46 has a third wire groove 461 for the spring body of the second wire spring 642 to limit and abut against. The locking frame 61 has a fourth wire groove 615 for the two ends of the second wire spring 642 to be arranged on the side facing the protective member 4. The second wire spring 642 provides the locking frame 61 with an elastic force for rotational reset. The bending direction of the second wire spring 642 is perpendicular to the first wire spring 641. The second wire spring 642 is bent in a normal state, and the protective member 4 is in a locked state. When the protective member 4 is in an unlocked state, the locking portion 631 is disengaged from the locking groove 322, and the second wire spring 642 drives the locking frame 61 to rotate in a direction away from the protective member 4.

[0056] Reference Fig.10 In order to prevent the locking frame 61 from rotating too much when resetting and the protective member 4 from being installed in rotation, the mounting housing 3 also includes a limit frame 34. The limit frame 34 is located on the inner side of the protective member 4, and the limit frame 34 covers the locking assembly 6. The limit frame 34 and the protective member 4 are plugged and fixed, and the limit frame 34 is rotatably installed with the decorative strip 32 on the side away from the locking groove 322. The decorative strip 32 has a second rotating shaft 35 that cooperates with the limit frame 34. The first elastic member 5 is installed on the second rotating shaft 35. The first elastic member 5 is a torsion spring member, and its two ends are respectively abutted against the limit frame 34 and the inner side of the protective member 4, which can drive the protective member 4 to always rotate outward.

[0057] The limiting frame body 34 has a limiting rotation groove 341 for the locking frame 61 to rotate, and the bottom wall of the limiting rotation groove 341 has a positioning surface 3411. When the locking frame 61 abuts against the positioning surface 3411, the protective member 4 is in a locked state. The limiting frame body 34 also has a second limiting slide groove 342 corresponding to the first limiting slide groove 44. The two limiting slide grooves can limit the sliding of the locking member 63 and improve the stability of the locking member 63 when sliding.

[0058] The implementation principle of a buttonless unlocking device in the embodiment of the present application is as follows: the protective member 4 has two states, namely, locked and unlocked: when the locking portion 631 is located in the locking groove 322, the protective member 4 is in the locked state, at which time the first driving inclined surface 6321 and the second driving inclined surface 6141 abut against each other, the locking frame 61 abuts against the positioning surface of the limiting frame body 34, and there is a rotation gap between the locking frame 61 and the inner side surface of the protective member 4, the first wire spring 641 is in a horizontal normal state, and the second wire spring 642 is in a bent normal state; When the support frame 1 approaches the outer side of the protective member 4, the first magnetic sheet 62 and the second magnetic sheet 11 attract each other, so that the locking frame 61 rotates toward the inner side of the protective member 4, and the two sets of locking components 6 rotate synchronously through the transmission member 65. Under the abutment of the first driving inclined surface 6321 and the second driving inclined surface 6141, the locking portion 631 is separated from the locking groove 322, and the locking frame 61 and the inner side of the protective member 4 are fitted. The spring body of the first wire spring 641 is bent toward the second rotation axis 35, and the middle angle of the second wire spring 642 is reduced, and the whole is horizontal. When the support frame 1 is disengaged from the insertion slot 321, the limiting frame body 34 and the protective member 4 rotate and reset under the action of the second elastic member 64. At the same time, the first wire spring 641 and the second wire spring 642 respectively drive the locking member 63 to slide and the locking frame 61 to rotate without external constraints.

[0059] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
