Description

Technical Field

[0001] The present invention relates to the technical field of firearm accessories, and in particular to a down-hanging lamp. Background Art

[0002] In the continuous development of firearm accessories, the demand for hanging lamps installed on the handguard of firearms has become increasingly prominent. In the prior art, one way is to fix the lamp on the M-LOK rail of the mechanical handguard through a clamping mechanism, such as the hanging lamp in patent CN220169328U. The clamping mechanism will occupy a large space and make the whole machine bloated; another way is to directly lock the lamp on the M-LOK rail with a locking screw and an M-LOK nut. The fastening screws of this type of product must pass through the entire lamp, which will cause insufficient utilization of the lamp space and the battery capacity must be reduced. However, due to the problem of the large space occupied by the clamping mechanism, the prior art cannot meet these requirements well. Therefore, it is of great practical significance to develop a hanging lamp that can optimize the clamping mechanism to reduce space occupation and ensure that there is enough space inside the lamp to increase the battery capacity under the condition of the smallest lamp shape. Summary of the invention

[0003] The embodiment of the present invention provides a down-hung lamp to solve the problem in the prior art that a clamping mechanism occupies a large space, resulting in a relatively reduced space inside the lamp for installing batteries.

[0004] To achieve the above-mentioned purpose, an embodiment of the present invention adopts the following technical scheme: a down-hung lamp, used to be installed on a handguard with an M-LOK slot of a firearm, the down-hung lamp includes a lamp body and a battery, the lamp body includes a mounting base and an irradiation lamp installed inside the mounting base and electrically connected to the battery, a battery mounting slot is formed on the mounting base, the battery is detachably installed in the battery mounting slot, a locking screw is arranged in the battery mounting slot, the locking screw passes through the bottom of the mounting base and is connected to the M-LOK nut, and the bolt head of the locking screw is located in the battery mounting slot, and an accommodating groove is formed in the battery mounting slot at the position for the locking screw to pass through, the accommodating groove is used to accommodate the bolt head of the locking screw, so that when the locking screw cooperates with the M-LOK nut to fix the mounting base on the handguard, the top height of the bolt head of the locking screw is equal to or lower than the height of the bottom surface of the battery mounting slot, and the battery includes a battery body, and a battery circuit board is arranged in the battery body.

[0005] Furthermore, an installation chamber is formed at one end of the mounting base close to the irradiation lamp, and a mounting hole connected to the battery mounting slot is opened on one side of the mounting chamber close to the battery mounting slot, and a battery buckle is arranged in the mounting chamber. The battery buckle is restricted by the mounting hole and only has a linear freedom close to or away from the battery mounting slot, and the end of the battery buckle close to the battery mounting slot can extend out of the mounting hole; a buckle return spring is arranged between the end of the battery buckle away from the battery mounting slot and the side wall of the mounting chamber, and the buckle return spring is used to keep the battery buckle in an initial position in the mounting chamber. When the battery buckle is in the initial position, the end of the battery buckle close to the battery mounting slot extends into the battery mounting slot, and a battery buckle slot hole is opened on one side of the battery body. When the battery is installed in the battery mounting slot, the end of the battery buckle can be embedded in the battery buckle slot hole.

[0006] Furthermore, a hole is opened above the installation chamber and a battery replacement button is accommodated therein. The battery replacement button is constrained by the installation chamber and only has longitudinal linear movement freedom. The bottom of the battery replacement button is connected to the bottom wall of the installation chamber by a button reset spring. A connecting groove that can accommodate a battery buckle is formed at the bottom of the battery replacement button. The connecting groove divides the bottom of the battery replacement button into two limit blocks. The button reset spring is arranged between the bottom surface of the limit block and the bottom surface of the installation chamber. Through grooves for the limit blocks and the button reset spring to pass longitudinally are formed on both sides of the battery buckle. A first inclined surface is formed on the side of the limit block, and a second inclined surface is formed on the side of the through groove close to the battery replacement button. When the battery replacement button moves downward, the two limit blocks move in the through grooves on both sides of the battery buckle, and the first inclined surface abuts against the second inclined surface. The downward movement of the battery replacement button can push the battery buckle away from the battery installation slot.

[0007] Furthermore, a mounting seat circuit board is arranged at a position below the battery mounting slot in the mounting seat, and a contact spring is arranged on the mounting seat circuit board. The bottom of one side of the contact spring is electrically connected to the mounting seat circuit board, and the other side of the contact spring has a protrusion. The protruding portion of the contact spring does not contact the mounting seat circuit board. The protruding portion of the contact spring is exposed in the battery mounting slot through a hole opened at the bottom of the battery mounting slot, and an auxiliary spring is arranged between the protruding portion of the contact spring and the mounting seat circuit board.

[0008] Furthermore, a power indicator light and a power indicator touch button are provided at the bottom of the battery body. The power indicator light and the power indicator touch button are electrically connected to the battery circuit board. The power indicator touch button transmits the indication signal showing the power to the battery circuit board and transmits it to the power indicator light through the battery circuit board.

[0009] Furthermore, a battery contact point is provided at the bottom of the battery body. When the battery is installed in the battery installation slot, the battery contact point is electrically connected to the mounting seat circuit board through the contact spring.

[0010] Furthermore, a TYPE-C socket electrically connected to the battery circuit board is provided at the bottom of the battery body.

[0011] The beneficial effects of the present invention are:

[0012] The down-hung lamp provided by the present invention uses locking screws and M-LOK nuts to lock the lamp body after the battery is removed onto the handguard, thereby avoiding the increase in the volume and weight of the lamp due to the clamping mechanism, and also avoiding the reduction in the volume of the installable battery due to penetrating the lamp.

[0022] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0023] like Figure 1-7 As shown, the present invention provides a down-hanging lamp, such as Figure 1 As shown, the under-hook lamp is used to be installed on a handguard 3 with an M-LOK slot 4 of a firearm. The under-hook lamp includes a lamp body 1 and a battery 2. The lamp body 1 includes a mounting base 101 and an irradiation lamp 108 installed inside the mounting base 101 and electrically connected to the battery 2. A transparent lampshade is provided at one end of the mounting base 101 close to the irradiation lamp 108, so that the light emitted by the irradiation lamp 108 can be irradiated to the outside of the mounting base 101 through the transparent lampshade;

[0024] The mounting base 101 is used to carry and install components. A battery mounting groove 112 is formed on the mounting base 101. The battery 2 is detachably mounted in the battery mounting groove 112. A locking screw 103 is arranged in the battery mounting groove 112. The locking screw 103 passes through the bottom of the mounting base 101 and is connected to the M-LOK nut 102, and the bolt head of the locking screw 103 is located in the battery mounting groove 112; the M-LOK nut 102 includes a limiting column and a clamping block, the limiting column and the clamping block are fixedly connected, a limiting body is arranged on the limiting column, the limiting column is used to limit the rotation angle of the M-LOK nut 102 in the M-LOK slot 4, and the rotation angle range of the M-LOK nut 102 in the M-LOK slot 4 is 90° (the connection method of the M-LOK nut 102 and the M-LOK slot 4 has multiple embodiments in the prior art, and the specific structure of the M-LOK nut 102 is not repeated here);

[0025] When it is necessary to install the mounting base 101 on the handguard 3, loosen the locking screw 103, adjust the direction of the limiting column of the M-LOK nut 102 to be consistent with the direction of the M-LOK slot 4, pass the clamping block through the M-LOK slot 4, and then put the limiting column into the M-LOK slot 4 to make the mounting base 101 close to the handguard 3, rotate the locking screw 103, and the limiting part rotates in the M-LOK slot 4 during the rotation. After the M-LOK nut 102 rotates 90°, the limiting part cannot continue to rotate in the M-LOK slot 4, and the relative position of the M-LOK nut 102 and the locking screw 103 is fixed, and the clamping block is stuck with the handguard 3, so that the relative position of the handguard 3 and the mounting base 101 is fixed.

[0026] like Figure 6As shown, a receiving groove 113 is formed in the battery mounting groove 112 at the position for the locking screw 103 to pass through, and the receiving groove 113 is used to accommodate the bolt head of the locking screw 103, so that when the locking screw 103 cooperates with the M-LOK nut 102 to fix the mounting base 101 on the handguard 3, the top height of the bolt head of the locking screw 103 is equal to or lower than the height of the bottom surface of the battery mounting groove 112; the battery 2 includes a battery body 26, and a battery circuit board is arranged in the battery body 26 (the power circuit board is not shown in the figure, and the power circuit board has multiple embodiments in the prior art, and its specific structure is not the technical problem to be solved by the present invention).

[0027] The mounting base 101 has a mounting chamber 115 formed at one end thereof near the irradiation lamp 108. A mounting hole 114 connected to the battery mounting slot 112 is formed at one side of the mounting chamber 115 near the battery mounting slot 112. A battery buckle 106 is arranged in the mounting chamber 115. The battery buckle 106 is restricted by the mounting hole 114 and has only a linear degree of freedom close to or away from the battery mounting slot 112. The end of the battery buckle 106 close to the battery mounting slot 112 can extend out of the mounting hole 114. The battery buckle 106 is away from the battery mounting slot 112. A buckle return spring 107 is provided between one end of the mounting groove 112 and the side wall of the mounting chamber 115. The buckle return spring 107 is used to maintain the initial position of the battery buckle 106 in the mounting chamber 115. When the battery buckle 106 is in the initial position, one end of the battery buckle 106 close to the battery mounting groove 112 extends into the battery mounting groove 112. A battery buckle slot hole 25 is provided on one side of the battery body 26. When the battery 2 is installed in the battery mounting groove 112, the end of the battery buckle 106 can be embedded in the battery buckle slot hole 25.

[0028] The installation chamber 115 has a hole above and accommodates a battery replacement button 104. The battery replacement button 104 is constrained by the installation chamber 115 and has only longitudinal linear motion freedom. The bottom of the battery replacement button 104 is connected to the bottom wall of the installation chamber 115 through a button return spring 105. Specifically, Figure 4As shown, a connecting groove 1042 capable of accommodating a battery buckle 106 is formed at the bottom of the battery replacement button 104, and the connecting groove 1042 divides the bottom of the battery replacement button 104 into two limit blocks 1043. The button reset spring 105 is arranged between the bottom surface of the limit block and the bottom surface of the installation chamber 115. Passing grooves 1062 for the limit blocks 1043 on the battery replacement button 104 and the button reset spring 105 to pass longitudinally are formed on both sides of the battery buckle 106, so that the battery buckle 106 can be embedded in the connecting groove 1042, and the side surface of the limit block 1043 has a contact surface with the battery buckle 106; more specifically, A first inclined surface 1041 is formed on the side of the limit block 1043, and a second inclined surface 1061 is formed on the side of the through groove 1062 close to the battery replacement button 104. When the battery replacement button 104 moves downward, the two limit blocks 1043 at the bottom of the battery replacement button 104 move in the through groove 1062 on both sides of the battery buckle 106, and the first inclined surface 1041 abuts against the second inclined surface 1061. Therefore, the downward movement of the battery replacement button 104 can push the battery buckle 106 away from the battery installation slot 112, so that the battery buckle 106 can be disengaged from the battery buckle slot hole 25, thereby unlocking the battery 2 and facilitating replacement.

[0029] A mounting seat circuit board 109 is arranged at a position below the battery mounting slot 112 in the mounting seat 101, and a contact spring 110 is arranged on the mounting seat circuit board 109. The bottom of one side of the contact spring 110 is electrically connected to the mounting seat circuit board 109, and the other side of the contact spring 110 has a protrusion. The protruding portion of the contact spring 110 does not contact the mounting seat circuit board 109. The protruding portion of the contact spring 110 is exposed in the battery mounting slot 112 through a hole opened at the bottom of the battery mounting slot 112. An auxiliary spring 111 is arranged between the protruding portion of the contact spring 110 and the mounting seat circuit board 109, and a seal is arranged between the contact spring 110 and the mounting seat 101 to prevent leakage.

[0030] In one embodiment of the present invention, Figure 3-7 As shown, a power indicator light 21 and a power indicator touch button 24 are provided at the bottom of the battery body 26. The power indicator light 21 and the power indicator touch button 24 are electrically connected to the battery circuit board. The power indicator touch button 24 transmits an indication signal showing the power to the battery circuit board and transmits it to the power indicator light 21 through the battery circuit board. By pressing the power indicator touch button 24, the power level of the battery 2 can be displayed through the power indicator light 21; when the battery 2 is charging, the current power level of the battery 2 can be known by observing the power indicator light 21.

[0031] In one embodiment of the present invention, Figure 3-7As shown, a battery contact point 22 is provided at the bottom of the battery body 26. When the battery 2 is installed in the battery mounting slot 112, the battery contact point 22 is electrically connected to the mounting seat circuit board 109 through the contact spring 110. The power of the battery 2 is introduced into the mounting seat circuit board 109 on the mounting seat 101 through the battery contact point 22.

[0032] In one embodiment of the present invention, Figure 7 As shown, a TYPE-C socket 23 electrically connected to the battery circuit board is provided at the bottom of the battery body 26 , and by using a corresponding charger, the charger can charge the battery 2 through the TYPE-C socket 23 .

[0033] The down-hung lamp uses a locking screw 103 and an M-LOK nut 102 to lock the lamp body 1 after the battery 2 is removed onto the handguard 3, thereby avoiding the increase in the volume and weight of the lamp due to the clamping mechanism, and also avoiding the reduction in the volume of the installable battery 2 due to penetrating the lamp.

[0034] The above-described embodiments only express the implementation methods of the present invention, but they cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
