[0002] 1. When a detachable battery is being charged, there must be metal terminals connecting the charger and the battery. During the charging process, the metal terminals of the charger carry a certain value of DC voltage. If this DC voltage is higher than the voltage stipulated by national safety regulations (for example, in China, the upper limit of the safe DC voltage is stipulated as 42V), then the charger needs to have relevant safety protection designs, and users cannot easily touch the metal terminals on the charger, otherwise, electric shock accidents are likely to occur. Most of the charging hardware terminals of similar products in the market are exposed, and the output voltage and current of the charger are controlled by the function of the combined circuit, which is technically difficult and costly. 2. When similar chargers in the market are charging, there is no fastening and anti-loosening structure for the battery. When the battery is being charged, the charger needs to be placed in a fixed direction, otherwise, it is easy to have poor contact between the charger and the battery, and the use of the charger has limitations.

The terms used in the specification of the present utility model are only for the purpose of describing specific embodiments and are not used to limit the present utility model.

[0033] In order to solve the problems in the prior art that the charger does not have a fastening and anti-loosening structure and most of the charging hardware terminals are exposed, resulting in poor contact after accidental touch or the DC high voltage exceeding the safety value being harmful to the human body, an anti-misoperation charger is proposed. The following will be combined with the attached Figures 1 to 8 A detailed description will be given to an anti-misoperation charger provided by an embodiment of the present utility model.

[0034] Please refer to Figures 1 to 4 , Figure 1It is a three-dimensional structural schematic diagram of an anti-mis-touch charger according to the present utility model. Figure 2 It is a partial exploded view of an anti-mis-touch charger according to the present utility model. Figure 3 It is a front view of an anti-mis-touch charger according to the present utility model. Figure 4 It is a top view of an anti-mis-touch charger according to the present utility model. An anti-mis-touch charger includes: a base 1 provided with a first groove 11. A metal terminal 111 and a liftable isolation cover 12 are provided in the first groove 11. The isolation cover 12 is located above the metal terminal 111 and is provided with a charging hole 122 through which the metal terminal 111 can pass. When the isolation cover 12 rises to the first position, the metal terminal 111 is covered by the isolation cover 12. When the isolation cover 12 descends to the second position, the metal terminal 111 passes through the charging hole 122 and extends outside the isolation cover 12.

[0035] A fixing plate 2 is vertically arranged with the base 1 and includes a sliding surface 21. A pair of slide rails 24 perpendicular to the base 1 are provided on the sliding surface 21. The battery fits against the sliding surface 21 and can slide along the slide rails 24 towards the isolation cover 12 and press the isolation cover 12 from the first position to the second position, and the battery contacts the metal terminal 111.

[0036] A first clamping assembly 23 is arranged in the fixing plate 2 and can protrude from the sliding surface 21 to be clamped with the isolation cover 12 to fix the isolation cover 12 at the first position.

[0037] Specifically, most of the chargers for electric tools in the prior art have a flat structure, and the battery is not fixed on the flat charger. There is a metal terminal 111 on it, and the metal terminal 111 is exposed. During the charging process, if someone touches the charger or the battery, it will cause a poor contact situation, affecting the charging progress. If not charging, the charging metal terminal 111 is exposed outside, posing a potential risk of electric shock to personnel.

[0038] The base 1 is used to place the battery. The function of the first groove 11 on the base 1 is to surround the charging metal terminal 111 inside. An isolation cover 12 is arranged in the first groove 11. The function of the isolation cover 12 is to cover the metal terminal 111 above it to achieve isolation from the outside world. The isolation cover 12 is buckled on the first groove 11. A fourth elastic member 121 is arranged at the lower part of the isolation cover 12. The fourth elastic member 121 can be a spring or other equivalent substitutes. The fourth elastic member 121 generates an upward elastic force on the isolation cover 12 to keep the isolation cover 12 in an upward trend. The isolation cover 12 can be pressed by the battery from the first position to the second position, or can be bounced from the second position to the first position by the fourth elastic member 121. When the isolation cover 12 is pressed by the battery, the fourth elastic member 121 contracts, and the isolation cover 12 moves from the first position to the second position. The metal terminal 111 penetrates through the charging hole 122 from the inside of the isolation cover 12 and exposes outside the isolation cover 12, and contacts the battery to charge the battery.

[0039] The base 1 and the fixing plate 2 are in an L-shaped integrated design. During the charging process, the main function of the fixing plate 2 is to fix the battery. The base 1 can place the battery. The slide rail 24 is in a right-angle design, which controls the battery from moving forward, backward, and to both sides, ensuring that the battery can only move in the vertical direction during the contact with the metal terminal 111. Therefore, during the charging process, it has the function of preventing bad contact caused by touching. A first clamping component 23 is also arranged on the fixing plate 2. The function of the first clamping component 23 is that when there is no battery charging, the isolation cover 12 is bounced to the first position by the fourth elastic member 121, and the first clamping component 23 is clamped with the isolation cover 12 to fix the isolation cover 12 in the first position. At this time, it is covered by the isolation cover. When someone touches the isolation cover 12 or presses the isolation cover 12 downward, the isolation cover 12 is fixed and cannot be pressed down, that is, the human hand cannot touch the metal terminal 111, playing a safety regulation protection role.

[0040] For environments such as hand-held power tools, the national regulated safety voltage is 42V. If the DC voltage is higher than the national regulated safety voltage, the charger needs relevant safety regulation protection. By setting the first groove 11 and the isolation cover 12 on the base 1, the metal terminal 111 is wrapped inside, avoiding the direct contact between the metal terminal 111 and the outside world. When charging is not required, the metal terminal 111 is bounced to the first position by the fourth elastic member 121, so that there is a distance between the top of the isolation cover 12 and the metal terminal 111, and at the first position, the isolation cover 12 is fixed by the first clamping component 23, preventing personnel from accidentally touching the metal terminal 111 or accidentally pressing the isolation cover 12; the slide rail 24 of the fixing plate 2 and the first clamping component 23 cooperate to fix the battery during the charging process, avoiding bad contact and enhancing the reliability during charging.

[0041] Please refer to Figure 5 and Figure 6, Figure 5 is a cross-sectional view of an anti-mis-touch charger according to the present utility model, Figure 6 and Figure 5 is an enlarged view of portion A1 of

[0042] In one embodiment, the first clamping assembly 23 includes a first clamping head 231 and a second clamping head 232 that are integrally connected, a first connecting member 233, a first nut 234, and a first elastic member 235. The first elastic member 235 is sleeved on the first nut 234. The first nut 234 is connected to the first connecting member 233. The first clamping head 231 and the second clamping head 232 are connected to the first connecting member 233 and protrude from the sliding surface 21, and can be synchronously ejected from the sliding surface 21 by the first elastic member 235.

[0043] Specifically, the first clamping head 231 is wedge-shaped, with a first wedge-shaped inclined surface 2311 on the upper side and a first clamping surface 2312 perpendicular to the sliding surface 21 on the lower side. The function of the first wedge-shaped inclined surface 2311 is that when the battery slides down from above, it exerts a squeezing effect on the first wedge-shaped inclined surface 2311, squeezing the first clamping head 231 into the sliding surface 21. As the battery continues to slide down, the first clamping head 231 slides across the surface of the battery. The first clamping surface 2312 can be used to limit the upward movement range of the isolation cover 12 to prevent it from disengaging from the first groove 11.

[0044] The second clamping head 232 is wedge-shaped, with a second wedge-shaped inclined surface 2321 on the lower side and a second clamping surface 2322 perpendicular to the sliding surface 21 on the upper side. The function of the second wedge-shaped surface 2321 is that when the battery is pulled upward in the slide rail 24, the isolation cover 12 comes into contact and squeezes with the second wedge-shaped inclined surface 2321, squeezing the second clamping head 232 from the outside of the sliding surface 21 into the inside of the sliding surface 21.

[0045] The first elastic member 235 can be a spring or an equivalent substitute for a spring. The first nut 234 and the first connecting member 233 are connected by a bolt connection. The function of the first elastic member 235 is to generate an elastic force towards the outside of the sliding surface 21 on the first connecting member 233, pushing the first connecting member 233 towards the sliding surface 21, so that the first clamping head 231 and the second clamping head 232 correspondingly pass through the sliding surface 21 and maintain a state of protruding outward.

[0046] When the battery slides down in the slide rail 24, the lower end of the battery contacts and presses against the first wedge-shaped inclined surface 2311 of the first chuck 231. The battery continues to slide downward, pressing the first chuck 231 inward toward the sliding surface 21. The first chuck 231 and the second chuck 232 are connected by a connecting member 233, and the second chuck 232 also enters the inside of the sliding surface 21 along with the first chuck 231. At this time, the restricting effect of the second clamping surface 2322 on the movement of the isolation cover 12 from the first position to the second position disappears, and the fourth elastic member 121 is compressed. The side wall of the battery slides across the first chuck 231 and rubs against the first chuck 231;

[0047] When the battery is pulled out upward in the slide rail 24, the first elastic member 235 synchronously pops the first chuck 231 and the second chuck 232 out from the inside of the sliding surface 21. This prevents personnel from touching the metal terminal 111, avoids electric shock, and enhances the safety regulations performance.

[0048] Please refer to Figure 6 and Figure 8 , Figure 6 is Figure 5 the enlarged view of A1 in Figure 8 is the three-dimensional structure diagram of the charging metal terminal of an anti-mis-touch charger described in the present invention.

[0049] In one embodiment, the isolation cover 12 is provided with a card slot 123, and the second chuck 232 is clamped in the card slot 123 to fix the isolation cover 12 at the first position.

[0050] Specifically, when the battery slides down in the slide rail 24, the lower end of the battery presses the first chuck 231 inward toward the sliding surface 21. The second chuck 232 and the first chuck 231 are connected by a connecting member 233, and the second chuck 232 also enters the inside of the sliding surface 21 along with the first chuck 231. At this time, the restricting effect of the second clamping surface 2322 on the movement of the isolation cover 12 from the first position to the second position disappears, and the fourth elastic member 121 is compressed. The battery presses the isolation cover 12 from the first position to the second position.

[0051] When the battery rises in the slide rail 24 and disengages from the isolation cover 12, the isolation cover 12 is elastically pushed upward by the fourth elastic member 121 and bounces from the second position to the first position. The side wall of the battery disengages from the first chuck 231, and the side wall of the isolation cover 12 disengages from the second chuck 232. After the isolation cover 12 rises to the second position, the first chuck 231 and the second chuck 232 are ejected from the inside of the sliding surface 21 by the first elastic member 235. The second chuck 232 is inserted into the card slot 123. The second chuck 232 is ejected from the sliding surface 21 by the first elastic member 235 and inserted into the card slot 123 of the isolation cover 12. When someone presses the isolation cover 12 above the isolation cover 12, the second clamping surface 2322 clamps the isolation cover 12 in the second position, preventing the second isolation cover 12 from descending. Enhance safety regulations and avoid electric shock.

[0052] Please refer back to Figure 2 , in one embodiment, two first chucks 231 and two second chucks 232 are provided and horizontally distributed.

[0053] Specifically, two first chucks 231 are provided, two second chucks are provided, and they are horizontally distributed. When the battery slides down from the slide rail 24, the bottom of the battery presses the two first chucks 231, causing the two first chucks 231 and the two second chucks 232 to enter the sliding surface 21 at the same time. The battery presses the isolation cover 12 from the first position to the second position, and the battery contacts the metal terminal 111. When the charging is over, the battery leaves upward from the slide rail 24, and the isolation cover returns to the first position. The two first chucks 232 are clamped in the card slot 123, which is beneficial to enhancing stability and preventing accidental contact with the isolation cover 12 and then pressing the metal terminal 111, resulting in electric shock.

[0054] Please refer back to Figure 5 and Figure 7 , Figure 5 is a cross-sectional view of a charger with anti-misoperation according to the present invention, Figure 7 is Figure 5 the enlarged view at A2 of

[0055] Specifically, the second elastic member 283 can be a spring or an equivalent substitute for a spring. The function of the second elastic member 283 is to generate an elastic force on the second connecting member 285 towards the outside of the sliding surface 21, pushing the second connecting member 285 towards the sliding surface 21, so that the third engaging head 281 passes through the third through hole 27 of the sliding surface 21 and maintains a state of protruding outwards.

[0056] The third engaging head 281 is wedge-shaped, with a third wedge-shaped inclined surface 2811 above and a third engaging surface 2812 perpendicular to the sliding surface 21 below. The function of the third wedge-shaped inclined surface 2811 is that when the battery slides down from above, pressing the third wedge-shaped inclined surface 2811, the third engaging head 281 will be squeezed into the sliding surface 21, and as the battery continues to slide down, the third engaging head 281 slides across the battery surface.

[0057] For example, when the battery slides down in the slide rail 24, the lower end of the battery touches and squeezes the third wedge-shaped inclined surface 2811, pressing the third engaging head 281 into the third through hole 27. When the upper end of the battery passes over the third engaging head 281, the second elastic member 283 pops the third engaging head 281 out of the third through hole 27, and the third engaging surface 2812 clamps the battery. This is beneficial to the stability during charging and prevents poor contact after being touched.

[0058] Please refer back to Figure 2 In one embodiment, first through holes 25, second through holes 26, and third through holes 27 are provided on the sliding plate surface corresponding to the first engaging head 231, the second engaging head 232, and the third engaging head 281. The first engaging head 231 enters and exits through the first through hole 25, the second engaging head 232 enters and exits through the second through hole 26, and the third engaging head 281 enters and exits through the third through hole 27.

[0059] Specifically, when the battery slides down from the slide rail 24, the battery closely adheres to the sliding surface 21 and slides down. The bottom of the battery contacts the second wedge-shaped inclined surface 2321, squeezing the second wedge-shaped inclined surface 2321 from outside the second through hole 26 into the second through hole 26. The bottom of the battery contacts the first wedge-shaped inclined surface 2311, squeezing the first engaging head 231 from outside the first through hole 25 into the first through hole 25.

[0060] For example, when the battery is pressed and slides down along the slide rail 24, the bottom end of the battery squeezes against the first inclined surface, squeezing the first engaging head 231 from outside the first through hole 25 into the first through hole 25. At the same time, the connecting member 233 connects the second engaging head 232 to enter the second through hole 26 from outside the second through hole 26. When the battery leaves the first through hole 25 and the second through hole 26, the fourth elastic member 121 pops the first engaging head 231 and the second engaging head 232 out of the first through hole 25 and outside the second through hole 26.

[0061] The bottom end of the battery presses against the third wedge-shaped inclined surface 2811, squeezing the third chuck 281 from outside the third through-hole 27 into the third through-hole 27. When the battery leaves the third through-hole 27, the fourth elastic member 121 pops the third chuck 281 out of the third through-hole 27. This improves the charging efficiency and avoids poor contact during charging.

[0062] Please refer to Figure 7 , Figure 7 is Figure 5 the enlarged view of part A2 in , in one embodiment, the fixing plate 2 further includes a control surface 22. A second groove 221 is provided on the control surface 22, and a control key 222 is liftably embedded in the second groove 221. A third elastic member 2222 for popping up the control key 222 is provided under the control key 222.

[0063] Specifically, the shape of the control key 222 is in the shape of a cover. The cover-shaped control key 222 is embedded in the second groove 221. A third elastic member 2222 is provided under the control key 222. The third elastic member 2222 can be a spring or an equivalent substitute for a spring. The third elastic member 2222 generates an upward elastic force on the control key 222, popping the control key 222 out of the second groove 221 to the control surface 22 and keeping the control key 222 protruding outside the control surface 22. At the end of charging, the charger can be quickly removed, with simple operation and high safety. It can prevent personnel from touching the metal terminals, thereby enhancing the safety compliance performance.

[0064] Please refer back to Figure 2 , in one embodiment, the control key 222 further includes a fourth chuck 2823, and the fourth chuck 2823 is clamped with the fixing plate 2 to limit the rising range of the control key 222.

[0065] Specifically, when the manual pressing of the control key 222 ends, the second elastic member 283 pops the control key 222 upward to the highest point. At this time, the fourth chuck 2823 is stuck on the fixing plate 2, preventing the first chuck 231 from popping out of the second groove 221, which is beneficial to increasing the stability during the charging process.

[0066] Please refer to Figure 7 , in one embodiment, the second clamping assembly 28 further includes a pressing inclined surface 284. The pressing inclined surface 284 is inclinedly connected to the upper end of the second connecting member 285. The control key 222 further includes an extension portion 2221, and the extension portion abuts against the pressing inclined surface.

[0067] Specifically, the extension part 2221 of the control key 222 is closely attached to the sliding surface 21. The bottom of the extension part 2221 contacts and presses the third wedge-shaped inclined surface 2811 of the second clamping component 28, and the second elastic member 283 is compressed. The second clamping component 28 contracts into the sliding surface 21 and enters the fixing plate 2. For example, when manually pressing the control key 222, the control key 222 sinks into the second groove 221, compresses the second elastic member 283, and the extension part 2221 presses. The third clamping head 281 is pushed into the third through hole 27, and the fourth elastic member 121 pops up the isolation cover 12. The isolation cover 12 is close to the battery, and at the same time, the battery is also popped up.

[0068] For example, when the battery slides down in the slide rail 24, the lower end of the battery touches the third wedge-shaped inclined surface 2811, presses the third clamping head 281 into the third through hole 27. When the upper end of the battery passes over the third clamping head 281, the second elastic member 283 pops the third clamping head 281 out of the third through hole 27, and the third clamping surface 2812 clamps the battery.

[0069] Please refer to Figure 8 , in one embodiment, there are two fourth elastic members 121 provided under the isolation cover 12, and the two fourth elastic members 121 are distributed at intervals.

[0070] Specifically, two mounting tubes 112 are arranged on both sides of the metal terminal 111, and two fourth elastic members 121 are correspondingly installed in the two mounting tubes 112. The function of installing the two fourth elastic members 121 is to increase stability and prevent jamming during the process of the elastic member popping out.

[0071] The operation process of this device is as follows:

[0072] Insert the battery into the slide rail 24 and press it down. The surface of the battery is closely attached to the sliding surface 21 of the fixing member and generates friction. The lower end of the battery first contacts the third wedge-shaped inclined surface 2811 of the third clamping head 281, and undergoes frictional extrusion on the third wedge-shaped inclined surface 2811, squeezing the third clamping head 281 from outside the third through hole 27 into the third through hole 27. The battery continues to slide down, and the third clamping head 281 generates friction on the surface of the battery;

[0073] The battery continues to slide down. The lower end of the battery contacts the first wedge-shaped inclined surface 2311 of the first clamping component 23, and undergoes extrusion friction on the first wedge-shaped inclined surface 2311, squeezing the first clamping head 231 from outside the first through hole 25 into the first through hole 25. The second clamping head 232 also changes synchronously with the first clamping head 231, squeezing from outside the second through hole 26 into the second through hole 26. The second clamping head 232 disengages from the clamping groove 123 of the isolation cover 12, and the clamping effect on the isolation cover 12 disappears;

[0074] The battery continues to move downward, and the lower end of the battery contacts the top of the isolation cover 12, pressing the isolation cover 12 from the first position to the second position. At this time, the metal terminal 111 passes through the charging hole 122 and contacts the lower end of the battery. The upper end of the battery slides across the second clamping assembly 28, and the third clamping head 281 pops out from the third through hole 27. The third clamping surface 2812 clamps the upper end of the battery. The fourth elastic member 121 generates an upward elastic force on the isolation cover 12 and the battery, making the upper end of the battery closely adhere to the third clamping surface 2812. At this time, the battery is in a rechargeable state and is fixed by the slide rail 24 from both sides and the rear, the sliding surface from the front, the second clamping assembly 28 from above, and the metal terminal 111 from below, and will not become loose;

[0075] When charging is completed and the battery needs to be removed, manually press the control key 222. When pressing the control key 222, the extension portion 2221 is squeezed on the pressing inclined surface 284, causing the second clamping assembly 28 to enter the third through hole 27 from outside the second through hole 26. The acting force of the second clamping assembly 28 on the battery disappears, and the fourth elastic member 121 bounces the isolation cover 12 and the battery upward. The battery bounces upward. At this time, the battery can be slid upward along the slide rail 24 and removed. At the same time, the third elastic member 2222 bounces the control key 222 back to its original position, and the fourth clamping head 2823 prevents the control key 222 from bouncing up. The isolation cover 12 is bounced from the second position to the first position, and the first clamping head 231 pops out from the first through hole 25 and inserts into the card slot 123 of the isolation cover 12 to fix the isolation cover 12 in the first position. At this time, even if the isolation cover 12 is accidentally touched or pressed, it will not move to the first position, preventing human limbs from contacting the metal terminal 111.

[0076] By providing a fixing plate on the base and a guide rail on the fixing plate to restrict the moving direction of the battery, the battery can only move in one direction, preventing the battery from being touched during charging and causing poor contact. A isolation cover is provided on the base, and a first clamping assembly is provided on the fixing plate. When not charging, the isolation cover is bounced up by a spring and keeps a certain distance from the charging metal terminal. The clamping assembly fixes the isolation cover. At this time, when pressing the isolation cover, the isolation cover will not be pressed down, that is, it will not contact the metal terminal, enhancing the safety regulations protection. After being accidentally touched, there will be no electric shock safety problems or poor contact.
