Description
Technical Field
The invention relates to the field of cups, in particular to a locking and unlocking mechanism and a cup.
Background
In order to prevent the thermos cup from being opened by being touched by other hard objects in the knapsack when the thermos cup is in the knapsack, a locking structure is generally added. When the lock catch is closed, the button of the thermos cup is pressed, the thermos cup cover cannot be opened, and only when the lock catch is opened, the button of the thermos cup is pressed, the thermos cup cover can be opened.
When the locking mechanism is used on an adult cup, the adult can clearly know the locking meaning, and then the lock catch of the cup is opened before the button is used for uncovering, and then the button is pressed down to smoothly open the cup cover. But problems arise when such a locking mechanism is used on a child's cup. When the infants are older, they cannot understand the meaning of locking, cannot understand why the locking mechanism is added, and cannot understand why the cover can be opened after unlocking. Also, they cannot understand whether the lock button is needed or not and under what circumstances the lock button is needed after drinking. Therefore, a new locking and unlocking mechanism needs to be designed, and the lock catch is not easy to be touched and opened by mistake while being abandoned.

Example 1
As shown in fig. 1, 2, 3 and 4, the present embodiment discloses a cup including a lock-unlock mechanism and a locked member 6.
As shown in fig. 1 to 11, a locking and unlocking mechanism comprises a mounting seat 3, a push plate 4, a locking piece 5, a first elastic piece 7 and two groups of control components 8;
the push plate 4 is movably arranged on the mounting seat 3, and the push plate 4 is provided with an initial working position and a trigger working position;
the locking piece 5 is movably arranged on the push plate 4, the locking piece 5 is used for being matched with an external locked piece 6, the locking piece 5 is provided with a locking working position and an unlocking working position, the locked piece 6 can be limited by the locking piece 5 when the locking piece 5 is in the locking working position, the locked piece 6 is not limited any more when the locking piece 5 is separated from the locked piece 6 when the unlocking working position is in the unlocking working position, the push plate 4 is matched with the locking piece 5, and the locking piece 5 is driven to move from the locking working position to the unlocking working position when the push plate 4 moves from the initial working position to the triggering working position;
the first elastic piece 7 is matched with the locking piece 5 and is used for resetting the locking piece 5 to a locking working position when the locking piece 5 is not acted by external force;
the two groups of control components 8 are respectively arranged at two sides of the push plate 4, and each control component 8 comprises a limiting latch hook 9 rotatably arranged on the mounting seat 3, a key rod 13 movably arranged on the mounting seat 3 and a second elastic piece 10;
the key rod 13 has a first working position and a second working position, and the second elastic piece 10 is matched with the key rod 13 and is used for resetting the key rod 13 to the first working position when the key rod 13 is not acted by external force;
the limiting latch hook 9 is provided with a first support leg 11 and a second support leg 12, the first support leg 11 is provided with a first side wall 14 opposite to the second support leg 12, the second support leg 12 is provided with a second side wall 15 opposite to the first support leg 11, the first side wall 14 is matched with the push plate 4, the second side wall 15 is used for being matched with the key rod 13, when the key rod 13 is reset to a first working position under the action of the second elastic piece 10, the key rod 13 drives the limiting latch hook 9 to rotate through the second side wall 15, and the limiting latch hook 9 drives the push plate 4 to reset to an initial working position through the first side wall 14; the key rod 13 can be matched with the push plate 4 to apply acting force to the push plate 4 when being pressed and moved from the first working position to the second working position;
of the two sets of control assemblies 8, when only the key lever 13 of one set of control assemblies 8 is pressed, the other set of control assemblies 8 can prevent the push plate 4 from moving;
when the key rods 13 of the two groups of control assemblies 8 are pressed, the two key rods 13 move to the second working position after being abutted against the push plate 4, and meanwhile, the push plate 4 is driven to move to the triggering working position, so that the push plate 4 drives the locking piece 5 to move to the unlocking working position.
The "external force for returning the lock member 5 to the lock operation position when the lock member 5 is not subjected to the external force" as referred to herein means a force pressed by the lock member 6 or a force pushed by the push plate 4. In practical use, the first elastic member 7 and the second elastic member 10 may take various structures, such as torsion springs, tension springs, and the like.
When only the key lever 13 of one set of control components 8 is pressed, for example, when the key lever 13 of the first set of control components 8 is pressed, the pressed key lever 13 applies a force to the push plate 4, the push plate 4 applies a force to the limit lock hook 9 of the second set of control components 8, the push plate 4 wants to move and needs to drive the limit lock hook 9 of the second set of control components 8 to rotate, but the limit lock hook 9 of the second set of control components 8 wants to rotate, and needs to overcome friction force, elastic force of the second elastic member 10 and the like, and the required force is very large, and the push plate 4 cannot be moved to the trigger working position only by pressing one key lever 13. When the key levers 13 of both sets of control modules 8 are pressed, the push plate 4 can be pressed because the key levers 13 are moved to the push plate 4 side and the second leg 12 is not blocked by the key levers 13. The locking and unlocking mechanism of the control assembly 8 is described in detail below, and as shown in fig. 12, the control assembly 8 is simplified to the model of fig. 12, which is used to describe the interaction and the working principle between the push plate 4, the limit lock hook 9 and the key lever 13. In the figure, the leftmost black circle is the movement circle center of the limiting lock hook 9, and the limiting lock hook 9 moves circularly around the circle center during movement. In the figure, two straight lines are respectively called a first pushing line a and a second pushing line b from bottom to top. The first push wire is flush with the lower edge of the push plate 4. The distance between the upper edge of the key lever 13 and the first pushing line is referred to as a first pushing distance. When the push plate 4 is pushed upwards in parallel, the force acting on the limiting latch hook 9 is mainly applied to the position marked as F1 on the figure; the limiting latch hook 9 moves around the center of a circle, and applies force to the key rod 13, and the main stressed position is marked as F2 in the figure.
The following is the theoretical basis for locking and unlocking the whole mechanism in operation:
when the push plate 4 is pushed upwards under the action of the key rod 13 at the other side, an acting force F1 is generated to the limiting lock hook 9, and the limiting lock hook 9 rotates along the circle center, so that an acting force F2 is generated to the key rod 13. Under the action of F2, if the push button bar 13 needs to be pushed upwards, the force of the second elastic element 10 of the push button bar 13 itself and the friction force of the push button bar 13 on the sliding rail must be overcome. Considering the arm lengths of the forces F1 and F2, the spring pressure and the friction between the push rod 13 and the mounting base 3, the push plate 4 pushes the push rod 13 to move upwards, and the required force is very large, so the limiting latch hook 9 can play a role in limiting the push plate 4 and the push rod 13. When the two key rods 13 move upwards to the first pushing line under the action of external force and begin to apply force F1 to the pushing plate 4, the key rods 13 do not obstruct the limiting lock hooks 9 to do circular motion because the key rods 13 are separated from the limiting lock hooks 9, namely the force F2 between the key rods 13 and the limiting lock hooks 9 disappears, namely the limiting lock hooks 9 are unlocked, the pushing plate 4 can continue to push upwards, the force F1 is applied to the pushing plate 4, the pushing plate 4 is pushed to move, and the pushing plate 4 moves upwards to the second pushing line (namely the pushing plate 4 is in a triggering working position).
The following are several different states of motion of this model under stress:
1. the clamping hook 24 on the push plate 4 generates enough displacement under the pushing force of the key rod 13, releases the locking hook of the push plate 4 and opens the locking.
When the key bar 13 is pushed upwards, the key bar translates to the first pushing wire, and then the force received by the key bar 13 is transferred to the push plate 4, so as to apply acting force to the push plate 4. The push plate 4 and the push rod 13, which are subjected to the force, translate upward together to move toward the second pushing line. At the same time, the circumferential movement of the limit lock hook 9 is not hindered, since the key lever 13 has already moved upwards. The limiting lock hook 9 can do circular motion around the circle center under the action of the push plate 4. When the lower edge of the push plate 4 reaches the position of the second push wire, the position where the push plate 4 moves has been displaced enough that the locking piece 5 is separated from the locked piece 6.
2. In the case where the key lever 13 is stationary, since the limit lock hook 9 is limited by the key lever 13, the upward movement of the push plate 4 is blocked.
Under the condition that the key rod 13 is static, the push plate 4 is pushed upwards, moves towards the second pushing line direction, and in the upward movement process, the push plate 4 transmits force to the limiting lock hook 9. However, since the lower side of the limit lock hook 9 is blocked by the key lever 13, the push plate 4 cannot perform circular motion around the center of the circle, and upward movement is blocked.
The locking and unlocking mechanism can prevent the locked piece 6 from being unlocked by false touching while omitting the lock catch, and can unlock the locked piece 6 only by simultaneously pressing the two key levers 13.
In other embodiments, the locking member 5 may also be movably disposed on the mounting base 3.
As shown in fig. 5, in the present embodiment, the mounting seat 3 has a first sliding rail 18, and the push plate 4 is slidably disposed on the first sliding rail 18; the mounting seat 3 is also provided with a second sliding rail 19, and the key rod 13 is arranged on the second sliding rail 19 in a sliding way.
As shown in fig. 5 and 6, in the present embodiment, the push plate 4 has a sliding groove 20, where the sliding groove 20 is slidably matched with the first sliding rail 18, and when the push plate 4 is in the initial working position, a bottom wall 21 of the sliding groove abuts against the first sliding rail 18.
As shown in fig. 5 and 6, in the present embodiment, the push plate 4 has a third slide rail 22, and the locking member 5 is slidably disposed on the third slide rail 22; the push plate 4 is provided with a limiting part 23 matched with the locking piece 5, and when the push plate 4 moves from an initial working position to a trigger working position, the locking piece 5 is driven to synchronously move by the limiting part 23.
As shown in fig. 5, in this embodiment, the first elastic member 7 is a first spring, one end of the first spring is matched with the mounting seat 3, and the other end of the first spring abuts against the locking member 5, so as to push the locking member 5 to move towards the push plate 4; the second elastic member 10 is a second spring, one end of the second spring is matched with the mounting seat 3, and the other end of the second spring is propped against the key rod 13 and is used for pushing the key rod 13 to move to one side far away from the push plate 4.
As shown in fig. 5, in the present embodiment, the first side wall 14 and the second side wall 15 are both flat surfaces, the push plate 4 has a first inclined surface 16 that mates with the first side wall 14, and the key lever 13 has a second inclined surface 17 that mates with the second side wall 15. The inclined surface means inclined with respect to the self-moving direction.

One is connected with a power supply, one is grounded, one signal output, and a capacitor 34 is connected in parallel with the power supply end and the grounding end. The signal output has a resistor 32. To realize low power consumption standby, the resistor 32 is set to a large resistance of 1M or more. The signal end is output and then connected to the MCU33, and the MCU is activated to work when the Hall sensor 30 detects the magnet. When the hall sensor 30 does not detect the magnetic field, the inside is in an OD off state, the output voltage of the signal end is pulled up by the power supply, and the system is in the lowest power consumption state. When the hall sensor 30 detects a magnetic field, the internal OD path, the signal line is pulled to ground. The MCU detects the low level of the signal line, is activated and wakes up, and starts working.
As shown in fig. 14, in actual use, the system of the cup of the present embodiment works as follows: after the power supply is powered on, the system executes initialization, sets the high and low levels of each interface, initializes each data and the like, and then enters into dormancy to wait for awakening.
There are two ways to wait for wakeup from sleep:
one is to wake up the cover, namely when the locking is opened or closed, the Hall sensor of the system is triggered, the MCU is activated, the system starts working, and whether the action set by the system, such as water temperature recording, temperature reminding, lamplight warning and the like, is required to be executed or not is judged. The electronic component system can judge whether the system setting action is required to be executed or not according to the current conditions such as water temperature, uncovering time, uncovering times and the like. If execution is not needed, the sleep is entered to wait for the next wake-up. If the sub-program is needed to be executed, the sub-program for executing the system action is operated to record data, measure temperature, feed back, transmit data and the like.
The other is the timing awakening, namely when the locking is closed, the system can be awakened at a fixed time, and the timing awakening system is used for realizing the functions of drinking water by reminding the drinking cup at fixed time, timing data transmission connection and the like. And after the execution is finished, the sleep is restarted.
