[0029] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0030] like Figure 1-8 As shown, a thermos cup with a double self-locking structure includes a cup body 1 and a cup cover. The cup cover is detachably connected to the cup body 1. The cup body 1 adopts a double-layer structure, and a gap is reserved between the two layers of the cup body 1, which is conducive to heat preservation. When in use, water or other liquids can be injected into the cup body 1 by opening the cup cover.

[0031] The cup cover comprises an upper cover 2 and a lower cover 3. The lower cover 3 is detachably connected to the cup body 1 so as to pour water into the cup body 1. One end of the upper cover 2 is hinged to one end of the lower cover 3, and the upper cover 2 can rotate and swing along the hinged end. A damper 4 is provided at one end of the lower cover 3 hinged to the upper cover 2, and a torsion spring is sleeved on the damper 4. The rotating shaft of the damper 4 is connected to the upper cover 2, and one end of the torsion spring is connected to the upper cover 2. The upper cover 2 can be driven to rotate and swing along the hinged end through the torsion spring, thereby opening the upper cover 2. The damper 4 can play a buffering role, so that the upper cover 2 is opened slowly during the process, thereby avoiding the situation where the user is injured due to the upper cover 2 opening too quickly, thereby improving practicality.

[0032] A mounting frame 5 is fixedly installed in the upper cover 2, and a control board 6, an identity recognition component and a drive component are installed on the mounting frame 5. The identity recognition component and the drive component are electrically connected to the control board 6 respectively. The identity recognition component is used to identify the user's identity information. Only when the identity recognition component recognizes the correct identity information will the drive component be controlled to work through the control board 6. A lock buckle 7 is provided on the upper cover 2, one end of the lock buckle 7 is connected to the output end of the drive component, and the other end can be respectively clamped and fixed with the lower cover 3 and the cup body 1. The lock buckle 7 can be driven to move by the drive component, so that the lock buckle 7 is clamped or separated with the lower cover 3 and the cup body 1 respectively. During specific use, when the upper cover 2 is in the closed state, the lock buckle 7 is respectively engaged with the lower cover 3 and the cup body 1; the user identifies the identity information through the identity recognition component, and when the identity recognition component identifies the correct identity information, it will send a signal to the control board 6, and then the control board 6 will control the drive component to work, driving the lock buckle 7 to separate from the lower cover 3 and the cup body 1 respectively; after the lock buckle 7 is separated from the lower cover 3, it will drive the upper cover 2 to rotate upward along the hinged end under the action of the torsion spring, thereby opening the upper cover 2 so that the user can drink water.

[0033] Specifically, a locking hole 31 is provided at a position corresponding to the lock buckle 7 on the lower cover 3, and a clamping boss 101 is provided at a position corresponding to the lock buckle 7 on the outer wall of the cup body 1, and the driving component can drive the lock buckle 7 to pass through the locking hole 31 and clamp with the clamping boss 101. When the upper cover 2 and the lower cover 3 are covered, the lock buckle 7 is driven by the driving component to pass through the locking hole 31 and clamp with the clamping boss 101. The thermos cup with a double self-locking structure can lock the lower cover 3 and the cup body 1 at the same time through the cooperation of the lock buckle 7, the locking hole 31 and the clamping boss 101, thereby preventing outsiders from opening the thermos cup at will, thereby improving the safety factor of the thermos cup.

[0034] The identity recognition component includes a sub-control board 8, which is fixedly mounted on the mounting frame 5. The sub-control board 8 is electrically connected to the control board 6. A fingerprint reader 9 is provided on the sub-control board 8. One end of the fingerprint reader 9 extends out of the upper end surface of the upper cover 2. The fingerprint reader 9 is used to identify the user's fingerprint information. During use, when the fingerprint reader 9 recognizes the correct fingerprint information, it will send a signal to the control board 6 through the sub-control board 8. At this time, the control board 6 will control the drive component to start working, so that the lock 7 is separated from the lower cover 3 and the cup body 1, so as to open the upper cover 2 for drinking water. In other embodiments, the fingerprint reader 9 can also be replaced with other identification methods, such as: swiping a card, a password, other existing biometric identification methods, etc.

[0035] The driving assembly includes a motor 10, which is fixedly mounted on the mounting frame 5. A rotatable transmission member 11 is provided on the upper cover 2. The output end of the motor 10 is connected to the transmission member 11. A screw 12 is provided at one end of the transmission member 11. A slider 13 is sleeved on the screw 12. The slider 13 is threadedly connected to the screw 12. The slider 13 is slidably limitedly connected to the upper cover 2, and the lock 7 is fixedly connected to the slider 13. During use, when the fingerprint reader 9 reads the correct fingerprint information, a feedback signal is given to the control board 6, and the control board 6 controls the motor 10 to work. The motor 10 drives the transmission member 11 to rotate, and drives the slider 13 to slide on the upper cover 2 through the screw 12. The slider 13 drives the lock 7 to move together, so that the lock 7 first disengages from the clamping boss 101 and then extends out of the locking hole 31; then the upper cover 2 will flip upward under the action of the torsion spring to open so that the user can drink water.

[0036] Specifically, a first bevel gear 14 is installed on the output end of the motor 10, and a second bevel gear 15 is provided at one end of the transmission member 11 away from the screw 12, and the first bevel gear 14 is meshed and connected with the second bevel gear 15. During operation, the first bevel gear 14 is driven to rotate by the motor 10, and the first bevel gear 14 drives the second bevel gear 15 to rotate synchronously, and the second bevel gear 15 drives the transmission member 11 and the screw 12 to rotate, thereby driving the slider 13 and the lock catch 7 to slide on the upper cover 2, so as to achieve the purpose of driving the lock catch 7 to extend into or out of the locking hole 31.

[0037] In order to limit the movement stroke and installation position of the slider 13, a first limiting groove 21 adapted to the slider 13 is provided on the upper cover 2, and the slider 13 is limited in the first limiting groove 21 and can slide in the first limiting groove 21. In specific operation, the slider 13 can be driven to slide in the first limiting groove 21 by the transmission member 11. When the slider 13 slides to the limit position, it will abut against the side wall of the first limiting groove 21. The slider 13 is limited by the first limiting groove 21, which can not only prevent the slider 13 from rotating with the transmission member 11, but also limit the movement stroke of the slider 13, and prevent the slider 13 from falling out of the screw rod 12, thereby ensuring that the lock buckle 7 can extend into or out of the locking hole 31, thereby improving the stability of the structure and the accuracy of the transmission.

[0038] The upper cover 2 is provided with a second limiting groove 22 adapted to the lock buckle 7. The lock buckle 7 is limited in the second limiting groove 22 and slidably cooperates with the second limiting groove 22. The lock buckle 7 is limited by the second limiting groove 22, so that the lock buckle 7 can be limited and fixed in the upper cover 2, thereby improving the stability of the structure.

[0039] In order to limit the movement direction of the lock buckle 7, two guide ridges 23 are provided on the inner side wall of the second limiting groove 22, and two guide slots 71 are provided on the outer side wall of the lock buckle 7. Each guide ridge 23 is respectively inserted into a corresponding guide slot 71, and the guide ridge 23 is slidably engaged with the guide slot 71. When the slider 13 drives the lock buckle 7 to move, the guide slot 71 will slide on the guide ridge 23. The movement direction of the lock buckle 7 can be limited by the cooperation between the guide ridge 23 and the guide slot 71, so that the lock buckle 7 can accurately pass through the locking hole 31 and be engaged and fixed with the engaging boss 101, thereby improving the transmission accuracy and working stability.

[0040] In order to achieve automatic locking, a Hall switch 16 is provided on the control board 6, and a magnetic member 17 is provided on the lower cover 3 at a position corresponding to the Hall switch 16. When the user pushes the upper cover 2 to flip downward along the hinged end, after the upper cover 2 and the lower cover 3 are closed, the Hall switch 16 is just aligned with the magnetic member 17. At this time, the Hall switch 16 senses the magnetic member 17 and sends a signal to the control board 6. The control board 6 controls the motor 10 to work, drives the transmission member 11 to rotate, drives the lock buckle 7 to extend into the locking hole 31, and passes through the locking hole 31 to engage with the clamping boss 101, thereby achieving the purpose of locking the upper cover 2, the lower cover 3 and the cup body 1. In this embodiment, the magnetic member 17 is a permanent magnet.

[0041] A battery 18 is fixedly mounted on the mounting frame 5. The battery 18 is electrically connected to the control board 6. The battery 18 is used to supply power to the control board 6 so that the control board 6 can control the motor 10 to work. A magnetic charging connector 19 is provided on the auxiliary control board 8. The magnetic charging connector 19 extends out of the upper end surface of the upper cover 2. The magnetic charging connector 19 is used to charge the battery 18 with an external power supply. An indicator light 20 is also provided on the auxiliary control board 8. The indicator light 20 can be used to display the status of the thermos cup, for example: a red light is on when charging, and a green light is on when fully charged.

[0042] In order to connect and fix the lower cover 3 with the cup body 1, a connecting post 32 is provided in the lower cover 3. The connecting post 32 extends into the cup body 1 and is threadedly connected to the inner wall of the cup body 1. When water needs to be added, the upper cover 2 can be opened, and the lower cover 3 can be rotated to separate the connecting post 32 from the cup body 1, so that water can be added to the cup body 1; after the water is added, the connecting post 32 is reinserted into the cup body 1, and the connecting post 32 and the cup body 1 are tightened to connect and fix the lower cover 3 with the cup body 1.

[0043] In order to facilitate drinking water, a straw 33 is provided on the lower cover 3 and penetrates the lower cover 3, and one end of the straw 33 extends into the cup body 1. During use, when the upper cover 2 and the lower cover 3 are opened, the liquid contained in the cup body 1 can be sucked through the straw 33.

[0044] Working principle:

[0045] Normally, the lower cover 3 is fixedly connected to the cup body 1, and the upper cover 2 covers the lower cover 3. When drinking water is needed, the user can place his finger on the fingerprint reader 9. After the fingerprint reader 9 reads the correct fingerprint information, it sends a signal to the control board 6; the control board 6 immediately controls the motor 10 to work, the motor 10 drives the first bevel gear 14 to rotate, the first bevel gear 14 drives the second bevel gear 15 to rotate, the second bevel gear 15 drives the transmission member 11 and the screw 12 to rotate, the screw 12 drives the slider 13 to slide in the first limit groove 21, and the slider 13 drives the lock buckle 7 to slide on the guide convex strip 23, so that the lock buckle 7 first disengages from the clamping boss 101, and then extends out of the locking hole 31; when the lock buckle 7 extends out of the locking hole 31, it will push the upper cover 2 to flip upward along the hinge end under the action of the torsion spring, so as to open the upper cover 2; after the upper cover 2 is opened, the user can absorb the water in the cup body 1 through the straw 33 to realize the function of drinking water.

[0046] When the upper cover 2 needs to be covered after drinking water is finished, the upper cover 2 is pushed to flip downward. When the upper cover 2 and the lower cover 3 are covered, the Hall switch 16 is aligned with the magnetic member 17. The Hall switch 16 will send a signal to the control board 6, and the control board 6 will control the motor 10 to work, drive the transmission member 11 and the screw 12 to rotate, and the screw 12 drives the slider 13 and the lock 7 to move, so that the lock 7 extends into the locking hole 31 first, and passes through the locking hole 31 to engage with the engaging boss 101, thereby locking the upper cover 2, the lower cover 3 and the cup body 1 together.

[0047] The thermos cup can achieve double self-locking through the lock buckle 7, locking the upper cover 2 and the lower cover 3, and also locking the upper cover 2 and the cup body 1, which can effectively improve the safety factor of the thermos cup, thereby preventing outsiders from opening the thermos cup at will.

[0048] The above-mentioned specific implementation is a preferred implementation of the present invention, and is not intended to limit the specific implementation scope of the present invention. The scope of the present invention includes but is not limited to this specific implementation. All equivalent changes made in accordance with the present invention are within the protection scope of the present invention.
