Flashlight

Abstract

According to the flashlight, a first elastic reset piece is arranged on a shifting rod in a sleeving mode, a second elastic reset piece is arranged at a first end, and when the first end of a sleeving piece is pressed to swing downwards, the second elastic reset piece is integrally compressed on one side of the first elastic reset piece; when the hand is released, the first elastic reset piece and the second elastic reset piece act together to apply upward elastic force to the first end of the sleeving piece, so that the first end of the sleeving piece can rapidly swing upwards to drive the shifting rod to swing upwards, and the lower end of the shifting rod is separated from the control switch of the control circuit board. The situation that the lower end of the deflector rod still makes contact with the control switch of the control circuit board after the hand is released due to the fact that the deflector rod cannot be driven to be lifted upwards after elasticity of a single silicon rubber sleeve descends is avoided, the flashlight is high in reliability, in addition, the rebound strength of the first end of the sleeving piece can be increased by arranging the first elastic reset piece and the second elastic reset piece at the same time, and the pressing hand feeling of a user is improved.

Description

Technical Field

[0001] The utility model belongs to the technical field of lamps, and particularly relates to a flashlight. Background Art

[0002] As a handheld electronic lighting tool, the flashlight has a wide range of applications and can be used for outdoor or indoor operations. Specifically, the flashlight includes a housing, a lighting component, a power supply component, and a control circuit board. Generally, buttons are installed on the housing to control various operations such as turning the flashlight on and off. However, the existing button structure is simple. Some directly insert a silica gel sleeve into the button. When the button is pressed, the silica gel sleeve deforms, enabling the lower end of the button to touch the control circuit board switch for various operations. However, due to the low degree of recovery of the silica gel sleeve after deformation, when the silica gel sleeve loses its elasticity after long-term use, it is sometimes easy to cause the silica gel sleeve to be unable to drive the button to rise, resulting in the lower end of the button still contacting the button circuit board switch after rising a small distance, making it impossible to turn off the flashlight, with low reliability. Moreover, after the silica gel sleeve lacks elasticity, the pressing feel becomes poor, resulting in an unsatisfactory user experience. Content of the Utility Model

[0003] (I) Purpose of the Utility Model

[0004] In order to overcome the above deficiencies, the purpose of the present utility model is to provide a flashlight to solve the technical problem that the existing flashlight button uses a silica gel sleeve for springback and reset. After long-term use, the elasticity of the silica gel sleeve decreases, the flashlight button cannot be completely separated from the control button, and the flashlight cannot be controlled, resulting in low reliability.

[0005] (II) Technical Solution

[0006] To achieve the above purpose, the technical solution provided by the present application is as follows:

[0007] A flashlight, comprising: a housing, a light-emitting component and a power supply component arranged inside the housing, a control circuit board electrically connected to the light-emitting component and the power supply component, a control switch arranged on the control circuit board, a lever hinged to the housing, the lower end of the lever extending into the housing, the upper end extending out of the housing, a first elastic reset member sleeved on the upper end of the lever and having its lower end abutted against the housing, a sleeve member sleeved on the upper end of the lever and including a first end close to the control switch and a second end far from the control switch, and further comprising a second elastic reset member, the upper end of which abuts against the first end of the sleeve member and the lower end of which abuts against the housing;

[0008] In this application, a first elastic reset member is sleeved on the lever, and a second elastic reset member is arranged on the first end. When the first end of the fitting member is pressed to swing downward, one side of the first elastic reset member and the whole of the second elastic reset member are compressed. The lever swings downward and the lower end presses the control switch of the control circuit board. When the hand is released, the first and second elastic reset members act together to apply an upward elastic force to the first end of the fitting member, so that the first end of the fitting member can swing upward rapidly, driving the lever to swing upward, and separating the lower end of the lever from the control switch of the control circuit board, avoiding the situation that a single silicone sleeve cannot drive the lever to lift upward after the elasticity decreases, resulting in the lower end of the lever still contacting the control switch of the control circuit board after the hand is released. The flashlight of this application has high reliability. In addition, setting the first and second elastic reset members at the same time can increase the resilience of the first end of the fitting member and improve the pressing feel of the user.

[0009] In some embodiments, a convex portion is formed by the outward protrusion of the second end of the fitting member, and a limiting groove for the convex portion to be embedded is provided at the position of the housing corresponding to the convex portion of the fitting member;

[0010] The fitting member can be limited by embedding the second end of the fitting member into the limiting groove of the housing, avoiding the excessive upward swing amplitude of the fitting member.

[0011] In some embodiments, a first installation groove for the upper end of the lever to be embedded is provided on the fitting member;

[0012] The stable connection between the fitting member and the lever can be realized by setting the first installation groove.

[0013] In some embodiments, the fitting member and the housing are respectively provided with a second installation groove and a third installation groove for the two ends of the second elastic reset member to be embedded at the positions corresponding to the two ends of the second elastic reset member;

[0014] The stability of the connection between the second elastic member and the fitting member and the housing can be realized by setting the second and third installation grooves.

[0015] In some embodiments, the control switch is a micro switch;

[0016] Since the contact spacing of the micro switch is relatively small, it can bounce up completely when the lower end of the lever separates from it by a small distance. The first and second elastic reset members can also separate the lower end of the lever from the control switch of the control circuit board under the action of a small elastic force, ensuring the reliability of the flashlight control.

[0017] In some embodiments, anti-slip lines are provided on the upper end surface of the fitting member;

[0018] Setting the anti-slip lines can prevent the sliding between the hand and the fitting member when pressing the fitting member.

[0019] In some embodiments, the first elastic reset member is a silicone sleeve, and the second elastic reset member is a spring. Description of the Drawings

[0028] To make the objectives, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below in conjunction with the specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present utility model. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily obscuring the concepts of the present utility model.

[0029] A flashlight provided by the present utility model includes: an outer shell 1, a light-emitting component and a power supply component arranged inside the outer shell 1, a control circuit board 5 electrically connected to the light-emitting component and the power supply component, a control switch 501 arranged on the control circuit board 5, a lever 3 hinged to the outer shell 1, the lower end of the lever 3 extending into the outer shell 1 and the upper end extending out of the outer shell 1, a first elastic resetting member 7 sleeved on the upper end of the lever 3 and having its lower end abutted against the outer shell 1, a fitting 2 sleeved on the upper end of the lever 3, including a first end close to the control switch 501 and a second end far from the control switch 501, and further including a second elastic resetting member 4, the upper end of which abuts against the first end of the fitting 2 and the lower end of which abuts against the outer shell 1.

[0030] Specifically, a convex portion 201 is formed by the outward protrusion of the second end of the fitting member 2. The housing 1 is provided with a limiting groove for the convex portion 201 to be inserted at one end corresponding to the fitting member 2. The space of the limiting groove is slightly larger. When the first end of the fitting member 2 is pressed and swings to the maximum angle, the convex portion 201 abuts against the groove wall of the limiting groove, preventing the fitting member 2 from swinging upward continuously.

[0031] Specifically, the housing 1 includes a bottom cover and a top cover. The control circuit board 5, the lever 3, and the fitting member 2 are arranged on one side of the top cover.

[0032] Specifically, the lever 3 is integrally in a right-angle structure placed in an inverted manner. One side of the lower end of the lever 3 is provided with a contact point for pressing the control switch 501, and the other end of the lower end is provided with a hinge shaft 6 for hinging with the housing 1.

[0033] Specifically, the first elastic reset member 7 is a silica gel sleeve, and the second elastic reset member 4 is a spring.

[0034] Specifically, a first installation groove 202 is provided on the fitting member 2 for the upper end portion of the lever 3 to be inserted.

[0035] Specifically, when the first end of the fitting member 2 is pressed and swings downward, one side wall of the first elastic reset member 7 is compressed, and the second elastic reset member 4 as a whole is compressed. At this time, pressing the fitting member 2 drives the lever 3 to swing downward. When the lever 3 moves to the position of the control switch 501, it presses the control switch 501 to trigger the control circuit board 5 to control the light-emitting component. After releasing the hand, the compressed side wall of the first elastic reset member 7 and the second elastic reset member 4 expand, driving the first end of the fitting member 2 to swing upward. At this time, the fitting member 2 drives the lever 3 to swing upward, and its lower end is separated from the control switch 501.

[0036] Specifically, second installation grooves 203 and third installation grooves are respectively formed at both ends of the fitting member 2 corresponding to the second elastic reset member 4 and on the housing 1 for both ends of the second elastic reset member 4 to be inserted.

[0037] Preferably, a micro switch is used as the control switch 501 in this application.

[0038] Preferably, anti-slip lines 204 are provided on the upper end surface of the fitting member 2 in this application.
