DETAILED DESCRIPTION

[0034] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0035] Example 1

[0036] See also Figures 1 to 7A family safety door lock suitable for the elderly includes an outer lock shell 1, a lock core 2 and an inner lock shell 3. The lock core 2 is located between the outer lock shell 1 and the inner lock shell 3. A handle 11 is installed on the outer lock shell 1. The handle 11 is convenient for opening the door. A group of buttons 12 are arranged on the handle 11. The group of buttons 12 is arranged as larger physical buttons with corresponding numbers arranged on them, which is convenient for the elderly to observe and enter passwords to unlock the door. Compared with touch screen buttons, physical buttons are more suitable. A fingerprint identifier 13 and an outer screen 14 are also arranged on the handle 11. The fingerprint identifier 13 can unlock the door using fingerprints. A camera 15 is installed on the outer lock shell 1. The camera 15 can unlock the door using face recognition. 3 is provided with an inner screen 31 and a turning handle 32, the inner screen 31 can monitor the outside of the door by cooperating with the camera 15, a main board 33 is installed inside the inner lock shell 3, and a battery 4 is plugged into the main board 33. By setting a variety of unlocking methods, elderly users can unlock the door in a variety of ways, which improves the convenience of use. A guide cylinder 34 is installed on the inner wall of the inner lock shell 3, and the inner wall of the guide cylinder 34 is in sliding contact with the outer wall of the battery 4. The inner wall of the guide cylinder 34 and the outer wall of the battery 4 are provided with corresponding guide notches, so when the position of the battery 4 is reversed, the battery 4 cannot be inserted into the guide cylinder 34, so as to avoid the user installing the battery 4 reversely and causing the battery 4 to be unable to dock with the main board 33:

[0037] The push mechanism 5 is also included, which is used to disassemble and install the battery 4; the push mechanism 5 includes an I-shaped block 51, which is slidably installed on the bottom inner wall of the inner lock shell 3, and the bottom of the I-shaped block 51 is located outside the inner lock shell 3. The top of the I-shaped block 51 is connected to two vertical rods 52, and the two vertical rods 52 are respectively located on both sides of the main board 33. The top outer wall of the vertical rod 52 is connected to a support block 53, and the two support blocks 53 are mirror-imaged. Both of the two support blocks 53 are in contact with the bottom surface of the battery 4. When the I-shaped block 51 moves upward, it drives the two vertical rods 52 to move upward, and the two vertical rods 52 drive the two support blocks 53 to move upward, so that the two support blocks 5 3 lifts the battery 4 upward, and finally a part of the battery 4 is located outside the inner lock shell 3. At this time, the user can pull the battery 4 out upward, which is convenient for removing the battery 4. The top ends of the two vertical rods 52 are respectively connected to the mounting rods 54, and four connecting rods 55 are hinged on the mounting rods 54. The four connecting rods 55 are hinged on one end away from the mounting rods 54 with a clamping block 56. The connecting rod 55 between the clamping block 56 and the mounting rod 54 is inclined. A spring is arranged between the clamping block 56 and the mounting rod 54. The two clamping blocks 56 maintain a certain pressure on the two sides of the battery 4 through the elastic force of the spring. There is a space between the two clamping blocks 56 and the outer wall of the battery 4. The friction force is fixed, two abutment rods 57 are installed on the inner wall of the inner lock shell 3, and the two clamping blocks 56 are in contact with the two sides of the battery 4 respectively. The two abutment rods 57 are respectively located on the movement tracks of the two clamping blocks 56. When the two mounting rods 54 move downward, the four connecting rods 55 on the mounting rods 54 will support the clamping blocks 56, so that the two clamping blocks 56 clamp the battery 4. On the contrary, when the two mounting rods 54 move upward, the connecting rods 55 do not provide supporting force, so that the two clamping blocks 56 can slide on the surface of the battery 4, pulling the I-shaped block 51 downward, and the I-shaped block 51 drives the two mounting rods 54 to move downward through the two vertical rods 52, and the two clamping blocks 56 clamps the battery 4 and drives the battery 4 to move downward, so that the battery 4 is plugged into the main board 33, and the installation of the battery 4 is completed, achieving the effect of automatically installing the battery 4; through the setting of the pushing mechanism 5, when the user pushes the I-shaped block 51 upward, the two supporting blocks 53 can push the battery 4 upward, so that the battery 4 is automatically disconnected from the main board 33, which is convenient for the user to remove the battery 4; through the setting of the two clamping blocks 56, when the user pulls the I-shaped block 51 downward, the two clamping blocks 56 can clamp the battery 4 and drive the battery 4 to move downward, so that the battery 4 is docked with the main board 33, and the effect of automatically installing the battery 4 is achieved.

[0038] For further information, see Figures 8 to 9, the cover opening mechanism 6 is used for automatically opening the cover, and the cover opening mechanism 6 includes two flip covers 66, and the two flip covers 66 are rotatably installed on the top inner wall of the inner lock shell 3. The two flip covers 66 are mirror-imaged, and the two flip covers 66 are located above the battery 4. Two gears 62 are rotatably installed on the inner wall of the inner lock shell 3, and the two mounting rods 54 are respectively connected to the first rack 61 on the side away from each other. The ends of the two flip covers 66 away from each other are respectively hinged with pull rods 65, and the ends of the two pull rods 65 away from the flip covers 66 are respectively hinged with slide rods 63. The two slide rods 63 are slidably connected to the inner wall of the inner lock shell 3, and the bottom ends of the two slide rods 63 are respectively connected to the second rack 64. The two first racks 61 and the two second racks 64 are respectively symmetrically arranged with the center of the two gears 62 as the center of the circle. The two first racks 61 are respectively meshed with the two gears 62, and the two second racks 64 are respectively meshed with the two gears 62. The two vertical rods 52 are respectively engaged with the two gears 62, and the two vertical rods 52 drive the two installation rods 54 to move upward. The two installation rods 54 drive the two gears 62 to rotate respectively through the two No. 1 racks 61. When the two gears 62 rotate, they respectively drive the two No. 2 racks 64 to move downward. The two No. 2 racks 64 drive the two slide bars 63 to move downward, so that the two slide bars 63 drive the two flip covers 66 to flip upward through the two pull rods 65, so that the two flip covers 66 are opened. When the two slide bars 63 move upward, they drive the two flip covers 66 to flip and reset through the two pull rods 65. Through the setting of the cover opening mechanism 6, when the user removes the battery 4, the two flip covers 66 can automatically flip open. When the battery 4 is installed, the two flip covers 66 can automatically flip and close, eliminating the steps of disassembling and installing the outer shell, further optimizing the operating process of replacing the battery 4, and facilitating user operation.

[0039] Further, see Figure 10 to Figure 11The cam 73 is provided with a plurality of springs which are connected to the locking cam 74 so that the locking cam 73 is locked and the locking cam 73 is unlocked when the locking cam 73 is unlocked. The outer wall of the battery 4 is pressed against the inner lock shell 3 when the door is closed, and the inner lock shell 3 is vibrated. The vibration damping plate 74 and multiple springs can absorb part of the vibration potential energy, thereby reducing the vibration generated by the battery 4 when the inner lock shell 3 vibrates, and avoiding the battery 4 from vibrating for a long time and causing the interface between the battery 4 and the main board 33 to loosen due to long-term use. Through the setting of the vibration damping mechanism 7, the vibration damping plate 74 can press against the battery 4. When the inner lock shell 3 vibrates, the vibration damping plate 74 absorbs part of the vibration potential energy of the battery 4 through the cooperation of multiple springs to achieve the vibration reduction effect, and avoiding the battery 4 from vibrating for a long time with the inner lock shell 3. The interface between the battery 4 and the main board 33 is loosened and poor contact occurs. When the battery 4 is removed, the vibration damping plate 74 can automatically relax the pressure on the battery 4. After the battery 4 is installed, the vibration damping plate 74 can automatically press against the battery 4 to maintain the vibration reduction effect.

[0040] With the above structure, the working principle of the case is that when the battery 4 needs to be replaced, the I-shaped block 51 is pushed upward. When the I-shaped block 51 moves upward, it drives the two vertical rods 52 to move upward. The two vertical rods 52 drive the two support blocks 53 to move upward, so that the two support blocks 53 lift the battery 4 upward. At the same time, the two vertical rods 52 drive the two installation rods 54 to move upward. The two installation rods 54 drive the two gears 62 to rotate respectively through the two No. 1 racks 61. When the two gears 62 rotate, they drive the two No. 2 racks 64 to move downward respectively. The two No. 2 racks 64 drive the two slide bars 63 to move downward, so that the two slide bars 63 drive the two flip covers 66 to flip upward through the two pull rods 65, so that the two flip covers 66 are opened. When the two flip covers 66 are opened, the battery 4 is The battery 4 moves upward with the two support blocks 53, and finally a part of the battery 4 is located outside the inner lock shell 3. At this time, the user can pull the battery 4 out upward, and after replacing the new battery 4, insert the new battery 4 into the inner lock shell 3 from between the two flip covers 66. When the battery 4 moves downward, it first contacts the inner wall of the guide cylinder 34. Since the inner wall of the guide cylinder 34 and the outer wall of the battery 4 are provided with corresponding guide grooves, when the position of the battery 4 is reversed, the battery 4 cannot be inserted into the guide cylinder 34, so as to avoid the user installing the battery 4 reversely and causing the battery 4 to be unable to dock with the motherboard 33. After the battery 4 is inserted into the guide cylinder 34 in the correct direction, the bottom of the battery 4 contacts the two support blocks 53, and the two sides of the battery 4 contact the two clamping blocks 56 respectively. The connecting rod 55 is tilted, and the battery 4 is regarded as stationary. Since the two clamping blocks 56 maintain a certain pressure on both sides of the battery 4 through the elastic force of the spring, and there is a certain friction between the two clamping blocks 56 and the outer wall of the battery 4, when the two mounting rods 54 move downward, the four connecting rods 55 on the mounting rods 54 will support the clamping blocks 56, so that the two clamping blocks 56 clamp the battery 4. On the contrary, when the two mounting rods 54 move upward, the connecting rod 55 does not provide a supporting force, so that the two clamping blocks 56 can slide on the surface of the battery 4. Based on the above principle, when the battery 4 is placed, the user pulls the I-shaped block 51 downward, and the I-shaped block 51 drives the two mounting rods 54 to move downward through the two vertical rods 52. After the two clamping blocks 56 clamp the battery 4, they drive the battery 4 to move downward. The battery 4 moves downward, so that the battery 4 is plugged into the motherboard 33, and the installation of the battery 4 is completed. When the battery 4 is pulled out, when the two installation rods 54 drive the clamping block 56 to move upward into place, the clamping block 56 contacts the two abutment rods 57 respectively, so that the two abutment rods 57 temporarily block the two clamping blocks 56 from continuing to move upward, so that the two clamping blocks 56 move away from each other, loosening the clamping of the battery 4 without affecting the removal of the battery 4. While the two installation rods 54 move downward, the two No. 1 racks 61 drive the two No. 2 racks 64 to reset upward through the two gears 62, so that when the two slide bars 63 move upward, the two pull rods 65 drive the two flip covers 66 to flip and reset, so that the two flip covers 66 are closed, and the installation of the battery 4 is completed.The two flip covers 66 have the effect of closing; through the setting of the pushing mechanism 5, when the user pushes the I-shaped block 51 upward, the two support blocks 53 can push the battery 4 upward, so that the battery 4 is automatically disconnected from the main board 33, which is convenient for the user to remove the battery 4; through the setting of the two clamping blocks 56, when the user pulls the I-shaped block 51 downward, the two clamping blocks 56 can clamp the battery 4 and drive the battery 4 to move downward, so that the battery 4 and the main board 33 are connected, and the effect of automatically installing the battery 4 is achieved; through the setting of the opening mechanism 6, when the user removes the battery 4, the two flip covers 66 can automatically flip open, and when the battery 4 is installed, the two flip covers 66 can automatically flip close, eliminating the steps of removing and installing the shell, further optimizing the operation process of replacing the battery 4, and facilitating the user's operation.

[0041] When the two sliding bars 63 move up and down, they drive the curved rod 75 to move synchronously. When the battery 4 is not removed, the curved surface of the curved rod 75 abuts against the top ends of the two rotating rods 72, so that the bottom ends of the two rotating rods 72 apply a force facing the battery 4 to the spring plate 73, and the spring plate 73 applies a force facing the battery 4 to the vibration reduction plate 74 through the action of multiple springs, so that the vibration reduction plate 74 abuts against the outer wall of the battery 4. When the door is closed, the inner lock shell 3 is vibrated, and the vibration reduction plate 74 and multiple springs can absorb a part of the vibration potential energy, thereby reducing the vibration generated by the battery 4 when the inner lock shell 3 vibrates, thereby avoiding the battery 4 from loosening its interface position with the main board 33 due to long-term vibration after long-term use, thereby increasing the possibility of poor contact. When the battery 4 is removed, the curved rod 75 follows the two sliding bars 63 to move downward, so that the curved surface of the curved rod 75 slides downward along the top ends of the two rotating rods 72 until the curved rod 75 is out of contact with the two rotating rods 72. At this time, after the top ends of the two rotating rods 72 lose pressure, they rotate slightly. The bottom ends of the two rotating rods 72 are swung in the direction away from the battery 4 due to the elastic force generated on the spring plate 73, and the spring plate 73 and the vibration damping plate 74 also lose the force to resist the battery 4, which does not affect the removal of the battery 4. When a new battery 4 is installed, when the battery 4 is about to move downward into place, the arc rod 75 contacts the two rotating rods 72 again, so that the arc surface of the arc rod 75 drives the two rotating rods 72 to swing, so that the vibration damping plate 74 approaches and resists the outer wall of the battery 4 again to perform vibration reduction protection; through the setting of the vibration reduction mechanism 7, the vibration damping plate 74 can resist the battery 4. When the inner lock shell 3 vibrates, the vibration damping plate 74 absorbs part of the vibration potential energy of the battery 4 through the cooperation of multiple springs to achieve the effect of vibration reduction, so as to avoid the battery 4 from loosening the interface between the battery 4 and the main board 33 after the inner lock shell 3 vibrates for a long time, resulting in poor contact, and when the battery 4 is removed, the vibration damping plate 74 can automatically relax the pressure on the battery 4. After the battery 4 is installed, the vibration damping plate 74 can automatically resist the battery 4 to maintain the vibration reduction effect.

[0042] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
