Description

Technical Field

[0001] The utility model relates to the technical field of firearm accessories, and particularly relates to an under-hung lamp. Background Art

[0002] In the continuous development of firearm accessories, the demand for under-hung lamps installed on firearm handguards has become increasingly prominent. In the prior art, in one way, a clamping mechanism is used to fix the lamp on the M-LOK rail of the mechanical handguard. For such under-hung lamps as those in Patent CN220169328U, the clamping mechanism occupies a large space, making the whole mechanism bulky; in another way, the lamp is directly locked on the M-LOK rail with locking screws and M-LOK nuts. For such products, the fastening screws penetrate through the whole lamp, resulting in insufficient space utilization of the lamp and the necessity to reduce the battery capacity. However, due to the problem of large space occupation of the clamping mechanism in the prior art, these requirements cannot be well met. Therefore, it is of great practical significance to develop an under-hung lamp that can optimize the clamping mechanism to reduce space occupation while ensuring sufficient space inside the lamp to increase the battery capacity under the condition of a relatively small lamp shape. Summary of the Utility Model

[0003] An embodiment of the utility model provides an under-hung lamp to solve the problem in the prior art that the clamping mechanism occupies a large amount of space, resulting in a relatively reduced space inside the lamp for battery installation.

[0004] To achieve the above object, the embodiment of the utility model adopts the following technical solution: An under-hung lamp for installing on a handguard of a firearm with an M-LOK slot. The under-hung lamp includes a lamp body and a battery. The lamp body includes a mounting seat and an illuminating lamp installed inside the mounting seat and electrically connected to the battery. A battery installation groove is formed on the mounting seat. The battery is detachably installed in the battery installation groove. A locking screw is arranged in the battery installation groove. The locking screw passes through the bottom of the mounting seat and is connected to an M-LOK nut. The head of the locking screw is located in the battery installation groove. A receiving groove is formed at the position where the locking screw passes through the battery installation groove for receiving the head of the locking screw. When the locking screw cooperates with the M-LOK nut to fix the mounting seat on the handguard, the top height of the head of the locking screw is equal to or lower than the bottom height of the battery installation groove. The battery includes a battery body, and a battery circuit board is arranged inside the battery body.

[0005] Further, an installation chamber is formed at one end of the mounting base close to the irradiation lamp. An installation hole communicating with the battery installation groove is opened on one side of the installation chamber close to the battery installation groove. A battery buckle is arranged in the installation chamber. The battery buckle is restricted by the installation hole and has only a linear degree of freedom to approach or move away from the battery installation groove. And the end of the battery buckle close to the battery installation groove can extend out of the installation hole. A buckle return spring is arranged between the end of the battery buckle away from the battery installation groove and the side wall of the installation chamber. The buckle return spring is used to maintain the initial position of the battery buckle in the installation chamber. When the battery buckle is in the initial position, the end of the battery buckle close to the battery installation groove extends into the battery installation groove. A battery buckle slot hole is opened on one side of the battery body. When the battery is installed in the battery installation groove, the end of the battery buckle can be embedded into the battery buckle slot hole.

[0006] Further, an opening is formed above the installation chamber and a battery replacement button is accommodated therein. The battery replacement button is restricted by the installation chamber and has only a linear degree of freedom in the longitudinal direction. The bottom of the battery replacement button is connected to the bottom wall of the installation chamber through a button return spring. A connection groove capable of accommodating the battery buckle is formed at the bottom of the battery replacement button. The connection groove divides the bottom of the battery replacement button into two limiting blocks. The button return spring is arranged between the bottom surface of the limiting block and the bottom surface of the installation chamber. Through grooves for the limiting blocks and the button return spring to pass through longitudinally are formed on both sides of the battery buckle. A first inclined surface is formed on the side surface of the limiting block. A second inclined surface is formed on one side of the through groove close to the battery replacement button. When the battery replacement button moves downward, the two limiting 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 groove.

[0007] Further, an installation base circuit board is arranged at a position below the battery installation groove in the mounting base. A contact elastic piece is arranged on the installation base circuit board. One side bottom of the contact elastic piece is electrically connected to the installation base circuit board. The other side of the contact elastic piece has a protrusion. The protruding part of the contact elastic piece is not in contact with the installation base circuit board. The protruding part of the contact elastic piece is exposed in the battery installation groove through an opening at the bottom of the battery installation groove. An auxiliary spring is arranged between the protruding part of the contact elastic piece and the installation base circuit board.

[0008] Further, a power indicator light and a power indication touch button are arranged at the bottom of the battery body. The power indicator light and the power indication touch button are electrically connected to the battery circuit board. The power indication touch button transmits an indication signal for displaying the power to the battery circuit board and then transmits it to the power indicator light through the battery circuit board

[0009] Further, a battery contact point is arranged at the bottom of the battery body. When the battery is installed in the battery installation groove, the battery contact point is electrically connected to the installation base circuit board through the contact elastic piece.

[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 utility model are as follows:

[0012] For the underslung lamp provided by the present utility model, the lamp body after removing the battery is locked on the handguard by using locking screws and M-LOK nuts, which avoids increasing the volume and weight of the lamp due to the clamping mechanism and also avoids reducing the volume of the installable battery due to passing through the lamp.

Detailed Embodiments

[0022] The following will describe the specific embodiments of the present application in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustrating and explaining the present application, and are not intended to limit the present application.

[0023] As Figures 1-7 shown, the present utility model provides an under-mounted lamp, as Figure 1 shown, for being mounted on a forearm 3 of a firearm having M-LOK slots 4. The under-mounted lamp includes a lamp body 1 and a battery 2. The lamp body 1 includes a mounting seat 101 and an illuminating lamp 108 installed inside the mounting seat 101 and electrically connected to the battery 2. A transparent lamp cover is provided at one end of the mounting seat 101 close to the illuminating lamp 108, so that the light emitted by the illuminating lamp 108 can irradiate outside the mounting seat 101 through the transparent lamp cover;

[0024] The mounting seat 101 is used to carry and mount components. A battery mounting groove 112 is formed on the mounting seat 101. The battery 2 is detachably installed in the battery mounting groove 112. A locking screw 103 is provided in the battery mounting groove 112. The locking screw 103 passes through the bottom of the mounting seat 101 and is connected to an M-LOK nut 102, and the head of the locking screw 103 is located inside the battery mounting groove 112; The M-LOK nut 102 includes a limiting post and a clamping block. The limiting post and the clamping block are fixedly connected. A limiting body is provided on the limiting post. The limiting post is used to limit the rotation angle of the M-LOK nut 102 in the M-LOK slot 4. The rotation angle range of the M-LOK nut 102 in the M-LOK slot 4 is 90° (the connection method between 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 will not be elaborated herein);

[0025] When it is necessary to mount the mounting seat 101 on the forearm 3, loosen the locking screw 103, adjust the direction of the limiting post 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 post into the M-LOK slot 4 to make the mounting seat 101 close to the forearm 3. Rotate the locking screw 103. During the rotation process, the limiting part rotates in the M-LOK slot 4. 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 between the M-LOK nut 102 and the locking screw 103 is fixed. The clamping block is stuck with the forearm 3, so that the relative position between the forearm 3 and the mounting seat 101 is fixed.

[0026] As Figure 6As shown, a receiving groove 113 is formed at the position in the battery installation groove 112 where the locking screw 103 passes through. The receiving groove 113 is used to accommodate the 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 to the handguard 3, the top height of the head of the locking screw 103 is equal to or lower than the bottom surface height of the battery installation 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 there are various embodiments of the power circuit board in the prior art, and its specific structure is not the technical problem to be solved by the present utility model).

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

[0028] An opening is formed above the installation chamber 115 and a battery replacement button 104 is accommodated. The battery replacement button 104 is restricted by the installation chamber 115 and only has a linear degree of freedom in the longitudinal direction. 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, as Figure 4It is shown that a connection groove 1042 capable of accommodating the battery buckle 106 is formed at the bottom of the battery replacement button 104. The connection groove 1042 divides the bottom of the battery replacement button 104 into two limiting blocks 1043. The button return spring 105 is arranged between the bottom surface of the limiting block and the bottom surface of the installation chamber 115. Through grooves 1062 are formed on both sides of the battery buckle 106 for the limiting blocks 1043 and the button return spring 105 on the battery replacement button 104 to longitudinally pass through, so that the battery buckle 106 can be embedded into the connection groove 1042, and the side surface of the limiting block 1043 has a contact surface with the battery buckle 106; more specifically, a first inclined surface 1041 is formed on the side surface of the limiting block 1043, and a second inclined surface 1061 is formed on one side of the through groove 1062 close to the battery replacement button 104. When the battery replacement button 104 moves downward, the two limiting blocks 1043 at the bottom of the battery replacement button 104 move in the through grooves 1062 on both sides of the battery buckle 106, and the first inclined surface 1041 abuts against the second inclined surface 1061. Thus, the downward movement of the battery replacement button 104 can push the battery buckle 106 away from the battery installation groove 112, so that the battery buckle 106 is disengaged from the battery buckle slot hole 25, thereby realizing the unlocking of the battery 2 and facilitating replacement.

[0029] An installation base circuit board 109 is arranged at a position below the battery installation groove 112 in the installation base 101. A contact elastic piece 110 is arranged on the installation base circuit board 109. One side bottom of the contact elastic piece 110 is electrically connected to the installation base circuit board 109. The other side of the contact elastic piece 110 has a protrusion. The protruding part of the contact elastic piece 110 is not in contact with the installation base circuit board 109. The protruding part of the contact elastic piece 110 is exposed in the battery installation groove 112 by opening a hole at the bottom of the battery installation groove 112. An auxiliary spring 111 is arranged between the protruding part of the contact elastic piece 110 and the installation base circuit board 109. A seal is arranged between the contact elastic piece 110 and the installation base 101 to prevent leakage of electricity.

[0030] In one embodiment of the present utility model, as Figures 3-7 shown, a power indicator light 21 and a power indication touch button 24 are arranged at the bottom of the battery body 26. The power indicator light 21 and the power indication touch button 24 are electrically connected to the battery circuit board. The power indication touch button 24 transmits an indication signal for displaying the power to the battery circuit board and transmits it to the power indicator light 21 through the battery circuit board. When the power indication touch button 24 is pressed, the amount of power of the battery 2 can be displayed through the power indicator light 21; when the battery 2 is charging, the amount of power of the current battery 2 can be known by observing the power indicator light 21.

[0031] In one embodiment of the present utility model, as Figures 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 installation groove 112, the battery contact point 22 is electrically connected to the mounting base circuit board 109 through the contact elastic piece 110, and the power of the battery 2 is introduced into the mounting base circuit board 109 on the mounting base 101 through the battery contact point 22.

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

[0033] For this pendant lamp, the lamp body 1 after removing the battery 2 is locked on the handguard 3 by using the locking screw 103 and the M-LOK nut 102, which avoids increasing the volume and weight of the lamp due to the clamping mechanism, and also avoids reducing the volume of the installable battery 2 due to passing through the lamp.

[0034] The above embodiments only express the implementation manners of the present utility model, but should not be construed as limiting the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model shall be subject to the appended claims.
