[0028] Example 1

[0029] Reference Figure 1~Figure 3 , which is the first embodiment of the utility model, provides an anti-mistouch interlock button, including a pressing unit 100, including a shell 101, on which a first button 102 and a second button 103 are movably arranged, and a power-on component 300 is fixedly arranged on the second button 103; a sliding component 200, including an extrusion block 201 and a sliding plate 202; and a force amplification unit 400, including a fixed pulley 401, a movable pulley 402, and a rope body 403 wound around the fixed pulley 401 and the movable pulley 402, and one end of the rope body 403 is fixedly connected to the extrusion block 201. The first button 102 provides a limit for the second button 103, which is the first step to open the battery, increasing the complexity of triggering the battery switch. The first button 102 can drive the sliding component 200 to slide and then release the limit on the second button 103.

[0030] The extrusion block 201 is fixedly connected to the first button 102, and the sliding plate 202 includes an extrusion end 202a and a limiting end 202b, and the limiting end 202b is provided with a limiting groove 202b-1, and the limiting groove 202b-1 is semicircular. The contact surface between the extrusion block 201 and the sliding plate 202 is in an arc shape, which can reduce the friction of the contact so that the force of the first button 102 pressing down is better transmitted to the sliding plate 202.

[0031] The fixed pulley 401 is arranged on the upper side of the limiting groove 202b-1, and the movable pulley 402 is arranged on the lower side of the limiting groove 202b-1. A connecting handle 401a is fixed on the fixed pulley 401, and the connecting handle 401a is fixedly arranged on the housing 101. A blocking member 402a is fixedly arranged on the movable pulley 402.

[0032] The extrusion end 202a has a wedge-shaped cross section and includes an inclined surface 202a-1. The extrusion block 201 abuts against the inclined surface 202a-1. A first spring 202a-2 is fixedly provided on one side of the extrusion end 202a. The other end of the first spring 202a-2 is fixedly connected to the housing 101. The inclined surface 202a-1 is high at the right end and low at the left end. When the extrusion block 201 moves downward, it will be squeezed and then slide to the right.

[0033] The limiting end 202b is provided with a limiting groove 202b-1, and the limiting groove 202b-1 is semicircular.

[0034] Sliding bars 202c are fixedly arranged on opposite sides of the sliding plate 202, and a fixing plate 101b is fixedly arranged inside the housing 101. The fixing plate 101b is provided with a sliding groove 101b-1, and the sliding bar 202c is slidably arranged in the sliding groove 101b-1. The sliding groove 101b-1 and the sliding bar 202c are arranged in cooperation so that the sliding plate 202 can maintain a fixed horizontal height and slide left and right at the horizontal height.

[0035] The power-on assembly 300 further includes a column 302, and a limit ring 302a is fixedly disposed on the outer wall of the column 302, and the limit ring 302a divides the column 302 into two parts, an upper part and an lower part. A second spring 302b is also sleeved on the column 302, and the two ends of the second spring 302b are respectively fixedly connected to the limit ring 302a and the housing 101, and the second contact 301 is fixedly disposed at one end of the column 302 away from the second button 103. The second spring 302b can pull the limit ring 302a to move upward, so that the second button 103 that is pressed downward by an external force is reset.

[0036] The outer diameter of the limiting ring 302a is larger than the diameter of the limiting groove 202b-1, and the diameter of the limiting groove 202b-1 is slightly larger than the diameter of the column 302. A status display light 101c is also provided on the housing 101. The status display light 101c is electrically connected to the energy storage battery. When the energy storage battery is turned on to discharge externally, the status display light 101c is powered and illuminated, indicating that the battery is in a discharge state.

[0037] When the staff directly presses the second button 103, the first spring 202a-2 pushes the sliding plate 202, so that the limiting groove 202b-1 is close to the lower half of the column 302. The sliding plate 202 is located below the limiting ring 302a, so when the staff only presses the second button 103, the second button 103 cannot be pressed due to the obstruction of the sliding plate 202, the first contact 101a and the second contact 301 cannot contact, and the battery connection signal cannot be transmitted, so the energy storage battery cannot be turned on.

[0038] Example 2

[0039] Reference Figure 1~Figure 3 , which is the second embodiment of the present utility model, and this embodiment specifically illustrates the working principle of the anti-mis-touch interlock button in practical application.

[0040] Furthermore, there are two groups of force amplification units 400, which are distributed on both sides of the shell 101 and sandwich the power-carrying component 300 in the middle. The two ends of the blocking member 402a are respectively connected to the two movable pulleys 402, which play a role of limiting the lower end surface of the column 302.

[0041] When the energy storage battery needs to be turned on, the first button 102 needs to be pressed first. At this time, the extrusion block 201 descends and squeezes the inclined surface 202a-1. The sliding plate 202 resists the leftward elastic force of the first spring 202a-2 and slides to the right along the sliding groove 101b-1. When it moves to a certain distance, the limiting groove 202b-1 is separated from the limiting ring 302a, and the pressing state of the first button 102 is maintained. The second button 103 continues to be pressed. Due to the effect of the pulley group of the force amplification unit, when the end of the rope body 403 is pulled to the right, according to the force According to the principle of balance and distribution, the force applied by the movable pulley 402 in the vertical direction needs to be greater than the force in the horizontal direction at the end of the rope body 403 in order to make it move downward, that is, the pressing force for pressing the second button 103 to move downward needs to be greater than the force applied to the first button 102. Furthermore, the closer the slope of the end of the rope body 403 is to the horizontal, the more difficult it is to press the second button 103 to move downward. In actual applications, the vertical distance between the fixed pulley 401 and the sliding plate 202 can be adjusted according to the needs of the scene to control the slope of the rope body 403.

[0042] The main body 302 moves downward until the first contact 101a and the second contact 301 can contact each other. After the circuit is connected, the energy storage battery receives the circuit signal, thereby turning on the energy storage battery. Then, the second button 103 is first released, and the second spring 302b is restored to a free state from an extended state. The second button 103 is reset under the pull of the second spring 302b. Then, the first button 102 is released, and the first spring 202a-2 is restored to a free state from an extended state. The sliding plate 202 slides to the right under the pull of the first spring 202a-2. The inclined surface 202a-1 squeezes the squeezing block 201 to make it move upward, and the first button 102 is reset.

[0043] When the circuit signal needs to be triggered again to shut down the energy storage battery, the above operation can be repeated.

[0047] The function of the display screen 501 is to facilitate the user to grasp the remaining battery power in real time, clearly understand the battery consumption, and help the user to better manage energy and avoid the device from not working properly due to battery exhaustion. In addition, when the user is charging the energy storage lithium battery, knowing the remaining power helps the user avoid overcharging or over-discharging, thereby extending the battery life.

[0048] The function of the heat dissipation holes 502 is to help dissipate the heat generated by the energy storage battery during the charging and discharging process more quickly. Excessive temperature will affect the battery performance and even cause safety problems. For example, overheating may cause the battery to catch fire or be damaged, posing a threat to the safety of the family. The heat dissipation holes 502 can help dissipate the heat generated by the battery, improve the efficiency of heat conduction and dissipation, and help maintain a suitable operating temperature range, thereby maintaining the performance and safety of the battery.

[0049] The function of the fixing plate 503 and the sliding hanging plate 504 is to fix the energy storage battery on the wall by using them in conjunction with other tool accessories such as expansion nails, saving the space on the ground. The wall-mounted design can keep the energy storage system away from the ground, reducing the risk of being accidentally touched or damaged, and helping to improve the heat dissipation performance of the energy storage system, making it easier for the system to dissipate heat, helping to improve the safety of the system and extend the service life of the battery. Furthermore, a threaded hole is provided on the fixing plate 503, and a C-shaped sliding groove is provided on the sliding hanging plate 504. In actual application scenarios, users can choose the fixing plate 503 or the sliding hanging plate 504 according to actual needs. If there is no need to move the energy storage battery within a small range, screws can be passed through the threaded holes of the fixing plates 503 on the left and right sides of the battery body 500, and the screws can be fixed in the wall, so that the battery body 500 can be fixed to the wall immovably. When the user needs to move the battery body 500 within a small range, it is necessary to horizontally fix a sliding rod with the same shape as the C-shaped sliding groove at the corresponding position on the wall, align the C-shaped sliding groove with the sliding rod so that the two are embedded, and push the battery body 500 horizontally along the direction of the sliding groove to hang the battery body 500 on the wall.
