[0038] Referring to Figure 1 And Figure 2 As shown in the drawings, in an embodiment, the flashlight includes:

[0039] The outer periphery of the barrel body 100 is provided with a mounting groove 110.

[0040] The charging interface 200 is inserted into the mounting groove 110.

[0041] The circuit board assembly 300 is arranged in the barrel body 100. The charging interface 200 can be in contact with the circuit board assembly 300 to form an electrical connection, or it can be away from the circuit board assembly 300 to disconnect the electrical connection.

[0042] In the embodiment, the barrel 100 is the overall structural framework of the flashlight, which can be regular cylindrical or irregular elliptical. The barrel 100 surface can be provided with anti-slip stripes to ensure that the user can hold the flashlight firmly when using. The barrel 100 is internally structured with a receiving cavity for mounting other components of the flashlight (such as the circuit board assembly 300 and the button, etc.), and is provided with front and rear connecting ends along the length direction of the barrel 100, the front connecting end can be connected with the lampshade, and the rear connecting end can be connected with the battery, etc. The barrel 100 is provided with a mounting groove 110 on the outer periphery near the front end, which is radially arranged and can be circular, rectangular or other shapes. The edge of the mounting groove 110 is transitionally designed with the barrel 100, which does not affect the overall appearance of the barrel 100. The bottom of the mounting groove 110 is provided with a through hole, which facilitates the plug-in connection of the charging interface 200 with the circuit board assembly 300 through the through hole and the bottom of the mounting groove 110.

[0043] In the embodiment, the charging interface 200 can be a standard Type-C interface, Micro-USB or other standard interface, which is in the shape of a cuboid and is installed in the mounting groove 110 by sliding or elastic clamping, and can move along the radial direction of the barrel 100. The bottom of the charging interface 200 can be provided with a metal conductive contact, which can be in contact with the circuit board assembly 300 to form an electrical connection, or away from the circuit board assembly 300 to disconnect the electrical connection. The circuit board assembly 300 is fixed on the barrel 100 at the bottom of the mounting groove 110 by screws or clamps, and is provided with elastic probes or metal contacts thereon to ensure reliable contact with the charging interface 200. The circuit board assembly 300 can also be provided with a charging management chip and other electronic components, which can monitor the charging state of the battery in real time to ensure the stability of voltage, current and other parameters. When assembling the parts of the flashlight barrel 100, the circuit board assembly 300 can be first installed below the corresponding mounting groove 110 position of the barrel 100, and then the charging interface 200 and the circuit board assembly 300 are plugged in the mounting groove 110 to form an electrical connection, without welding, and the quick assembly can be completed in the narrow barrel 100, thereby simplifying the structure of the flashlight barrel 100, making the flashlight structure more compact, reducing the occupied space, and being conducive to the miniaturization design of the flashlight.

[0044] Referring to Figure 3 and Figure 4 In an embodiment, the charging interface 200 is provided with a conductive pin 210, and the circuit board assembly 300 is provided with a conductive hole 311 adapted to the conductive pin 210, and the conductive pin 210 can be in contact with the conductive hole 311 to form an electrical connection.

[0045] In the embodiment, the charging device is provided with the conductive needle 210, which is installed at the bottom of the charging interface 200 and faces the central axis direction of the barrel body 100. The circuit board assembly 300 is correspondingly provided with a cylindrical conductive hole 311. The conductive needle 210 is also cylindrical, which can be a flexible probe or a fixed probe. The depth of the conductive hole 311 is slightly greater than the insertion length of the conductive needle 210, so as to avoid structural deformation caused by excessive insertion and ensure that the conductive needle 210 is in close contact with the conductive hole 311 when inserted, thereby reducing the contact resistance therebetween. When the user needs to assemble the barrel body 100 part of the flashlight, the charging interface 200 is moved radially in the installation slot 110 along the barrel body 100, so that the conductive needle 210 at the bottom of the charging interface 200 penetrates the installation slot 110 and is inserted into the corresponding conductive hole 311 on the circuit board assembly 300. At this time, the charging interface 200 and the circuit board assembly 300 form a stable electrical connection without welding.

[0046] Referring to Figure 3 and Figure 4 , in an embodiment, the installation slot 110 includes:

[0047] The first avoiding hole 111 is arranged on the bottom surface of the installation slot 110, and the charging interface 200 at least partially passes through the first avoiding hole 111, so that the conductive needle 210 enters the conductive hole 311 to form an electrical connection.

[0048] In the embodiment, the first avoiding hole 111 is further arranged on the bottom surface of the installation slot 110. The first avoiding hole 111 can be rectangular or circular, and its size is slightly larger than the cross-sectional size of the charging interface 200, so that the charging interface 200 can smoothly slide through the first avoiding hole 111, avoid that the gap between them is too large, causing excessive shaking of the charging interface 200 when inserted, and also avoid that the hole diameter is too large to affect the structural strength of the bottom surface of the installation slot 110. The center of the first avoiding hole 111, the projection center of the conductive needle 210 at the bottom of the charging interface 200, and the center of the conductive hole 311 on the circuit board assembly 300 are on the same straight line perpendicular to the bottom surface of the installation slot 110. By correspondingly arranging the above components in sequence, it is ensured that when the charging interface 200 is moved radially along the barrel body 100 to the appropriate position, the conductive needle 210 at the bottom of the charging interface 200 can pass through the first avoiding hole 111 and accurately enter the corresponding conductive hole 311 on the circuit board assembly 300, thereby forming a reliable electrical connection. The space of the barrel body 100 is effectively utilized, and the relative positions of the charging interface 200 and the circuit board assembly 300 can be adjusted, so that the design of the flashlight is more flexible.

[0051] The cover plate assembly 130 is arranged in the mounting seat 120, and the cover plate assembly 130 is used for covering or exposing the charging interface 200.

[0052] In the embodiment, the mounting seat 120 can be divided into an avoiding part and a mounting part as a whole, and the size of the whole is matched with the mounting groove 110, the periphery side wall can be in contact with the inner side wall of the mounting groove 110, and the mounting seat 120 can slide in and out of the mounting groove 110. When mounted, the second avoiding hole 121 on the avoiding part is mounted corresponding to the first avoiding hole 111, and the charging interface 200 can pass through the first avoiding hole 111 and the second avoiding hole 121 in sequence. The mounting part is arranged beside the charging interface 200 (that is, the second avoiding hole 121), one end of the mounting part is in contact with the bottom of the mounting groove 110, and the other end of the mounting part is arranged close to the slot position of the mounting groove 110 and provided with the cover plate assembly 130. The cover plate assembly 130 mainly comprises a cover plate body and a rotating shaft 132, and the cover plate body is rotatably arranged on the mounting seat 120 through the rotating shaft 132. When the flashlight is normally used and does not need to be charged, the cover plate assembly 130 is in a covering state, the cover plate body is tightly covered above the charging interface 200, dust, water vapor and other impurities are effectively prevented from entering the charging interface 200 area, the charging interface 200 is well protected, and the service life of the charging interface 200 is prolonged. When the user needs to charge the flashlight, the cover plate assembly 130 is only needed to be slightly pushed to rotate around the rotating shaft 132, so that the charging interface 200 is exposed.

[0053] Referring to Figure 4 and Figure 5 In an embodiment, the mounting seat 120 is provided with a containing groove 122, one end of the containing groove 122 is arranged in an open mode, and the other end of the containing groove 122 is arranged in a closed mode, and the cover plate assembly 130 comprises:

[0054] The cover plate 131 is rotatably arranged in the mounting seat 120 through the rotating shaft 132;

[0055] The locking block 133 is slidably arranged in the containing groove 122 of the mounting seat 120, and one end of the locking block 133 is in abutment with the cover plate 131, and the locking block 133 is used for pushing the cover plate 131 to rotate, so that the cover plate 131 covers the charging interface 200;

[0056] The elastic member 134 is arranged between the locking block 133 and the containing groove 122, and the elastic member 134 is used for providing an elastic reset force for the locking block 133.

[0057] In the embodiment, the mounting base 120 is provided with a receiving groove 122 located at one side of the second avoiding hole 121 and shaped as a regular rectangle with one end open and the other end closed. The locking block 133 can enter the receiving groove 122 through the open end of the receiving groove 122. The locking block 133 is shaped as a wedge at one end and a rectangle at the other end. The wedge-shaped end extends out of the open end of the receiving groove 122 and abuts against the rotating side of the cover plate 131, and the rectangular part is adapted to the shape of the receiving groove 122 and can vertically slide in the receiving groove 122. The locking block 133 is provided with a circular hole at the side of the closed end for accommodating the elastic member 134. When the locking block 133 slides in the receiving groove 122, the wedge-shaped end can push the cover plate 131 to rotate around the rotating shaft 132, so as to realize the covering or uncovering of the charging interface 200 by the cover plate 131. The cover plate 131 is shaped as a rectangle as a whole and has a size corresponding to the cross section of the whole mounting groove 110 and can completely cover the mounting groove 110 and the charging interface 200. One end of the cover plate 131 is the rotating end and is rotatably arranged on the mounting base 120 through the rotating shaft 132. The rotating shaft 132 is located above the receiving groove 122 and the rotating end of the cover plate 131 can be abutted and pushed to rotate by the locking block 133. The movable end of the cover plate 131 covers the mounting groove 110 and the charging interface 200. The elastic member 134 is arranged between the locking block 133 and the closed end of the receiving groove 122, one end of the elastic member 134 is connected with the closed end of the receiving groove 122, and the other end is located in the circular hole at the bottom of the locking block 133 and connected with the top of the circular hole. When the locking block 133 slides to the closed end of the receiving groove 122 under the action of an external force, the elastic member 134 is compressed and stores elastic potential energy. When the external force disappears, the elastic member 134 pushes the locking block 133 to slide to the open end of the receiving groove 122 by virtue of the elastic restoring force, and in turn drives the cover plate 131 to rotate, so as to realize the automatic covering of the charging interface 200.

[0058] In the embodiment, in actual use, when the user needs to open the cover plate 131 to charge the flashlight, the movable end of the cover plate 131 is manually lifted, the rotating end of the cover plate 131 rotates around the rotating shaft 132, abuts against the locking block 133, and makes the locking block 133 slide to the closed end of the receiving groove 122 and compress the elastic member 134 at the same time. When the user removes the external force, the locking block 133 is reset under the action of the spring and abuts against and pushes the rotating end of the cover plate 131, so that the cover plate 131 rotates to close and completes the covering protection of the charging interface 200.

[0059] Referring to Figure 4 In an embodiment, the cover plate assembly 130 further includes:

[0060] The sealing ring 135 is sleeved on the outer circumferential side of the charging interface 200 and cooperates with the mounting base 120 to seal the first avoiding hole 111.

[0061] In the embodiment, the sealing ring 135 can be made of silicone rubber. The sealing ring 135 is annular and has a shape corresponding to the outer circumferential profile of the charging interface 200. When installed, the sealing ring 135 is tightly sleeved between the outer circumference of the charging interface 200 and the inner wall of the second avoiding hole 121 on the mounting seat 120, thereby forming an effective seal to prevent water from entering the inner part of the barrel 100 from the gap between the mounting seat 120 and the charging interface 200. At the same time, the vertical movement of the charging interface 200 is provided with a certain damping effect, so that the conductive needle 210 of the charging interface 200 is withdrawn from the conductive hole 311, and a certain resistance needs to be overcome, thereby better fixing the charging interface 200.

[0062] Referring to Figure 4 and Figure 5 In an embodiment, the end of the locking block 133 abutting against the cover plate 131 is provided with an inclined portion 1331, and the cover plate 131 is provided with a protruding portion 1311 matched with the inclined portion 1331. The inclined portion 1331 and the protruding portion 1311 are matched to push the cover plate 131 to rotate, so that the cover plate 131 covers the charging interface 200.

[0063] In the embodiment, the end of the locking block 133 abutting against the cover plate 131 is provided with an inclined portion 1331, and the inclined portion 1331 is directed away from the second avoiding hole 121 of the locking block 133. The shape of the inclined portion 1331 is uniformly distributed along the width direction of the locking block 133, and the length of the inclined portion 1331 is one third of the overall length of the locking block 133. The inclined portion 1331 can provide sufficient pushing area without affecting the structural strength of the locking block 133. Correspondingly, the cover plate 131 is provided with a protruding portion 1311 matched with the inclined portion 1331. The protruding portion 1311 can be integrally formed with the cover plate 131 or separately installed. The protruding portion 1311 is a regular triangular prism, and the edge line of the protruding portion 1311 is parallel to the rotation shaft 132 and provided with a circular arc-shaped transition chamfer. The length of the protruding portion 1311 is slightly greater than the length of the inclined portion 1331, so as to ensure the stability when the protruding portion 1311 contacts the inclined portion 1331. The position of the protruding portion 1311 is below the rotation shaft 132 of the cover plate 131 and staggered with the inclined portion 1331 at the same horizontal level. When the user rotates the cover plate 131 to open in the clockwise direction, the protruding portion 1311 below the rotation shaft 132 of the cover plate 131 is rotated in the clockwise direction and abuts against and pushes the locking block 133 to move downward in the accommodating groove 122, thereby compressing the elastic member 134. When the user removes the external force, the elastic member 134 releases the elastic force, the locking block 133 slides to the open end of the accommodating groove 122 under the action of the elastic force, and the inclined portion 1331 abuts against and pushes the protruding portion 1311 to rotate in the counterclockwise direction, thereby driving the cover plate 131 to rotate in the counterclockwise direction. The cover plate 131 covers the charging interface 200.

[0064] Referring to Figure 5As shown, in an embodiment, the side wall of the accommodating groove 122 is provided with a circular arc part 1221 for guiding the movement of the locking block 133.

[0065] In the embodiment, the overall shape of the accommodating groove 122 is rectangular, and the circular arc part 1221 is arranged on the two side walls of the accommodating groove 122 along the length direction of the accommodating groove 122. The length of the circular arc part 1221 is equivalent to the length of the locking block 133, and the starting position and the ending position of the circular arc part 1221 correspond to the limit positions of the movement of the locking block 133 in the accommodating groove 122, so as to ensure that the circular arc part 1221 can guide the movement of the locking block 133 in the whole sliding stroke. The cross section of the locking block 133 is approximately cylindrical, so as to ensure that the side surface of the locking block 133 can smoothly fit on the circular arc part 1221 in the movement process, and neither a too large gap to cause shaking nor too tight to hinder the movement. The stability and accuracy of the movement of the locking block 133 are improved.

[0066] In an embodiment, the mounting seat 120 and the mounting groove 110 are fixedly connected through threads.

[0067] In the embodiment, the outer side wall of the mounting seat 120 is provided with a threaded hole, and the threaded holes are symmetrically arranged on the mounting seats 120 on the two sides of the accommodating groove 122, so that the mounting seat 120 can be fixedly connected with the mounting groove 110.
