Description

A tail cap locking device and a work light Technical Field

[0001] This utility model relates to the field of lighting device technology, and more specifically, to a tail cover locking device and a work light. Background Technology

[0002] Work lights are widely used in outdoor operations, maintenance, and other applications due to their high illumination intensity and versatility. To facilitate battery replacement and improve maintenance efficiency, many work lights employ a removable battery design, with the battery compartment's structural design being particularly crucial. In existing technologies, the battery compartment is typically located in two locations: one is on the side of the light body, with a side cover for opening and closing; the other is at the end of the light body, with a tail cover for closing the battery compartment.

[0003] The latter structure typically connects the tail cover to the lamp body via a hinge, and the opening and closing of the tail cover is controlled by a push-button switch located on the other end of the lamp body, enabling one-button quick unlocking. This structure simplifies the operation process and improves the user experience. However, in actual use, because the push-button switch is exposed externally, it is easily affected by accidental touches or pressure, which can lead to the tail cover opening unexpectedly, the battery being exposed, or even falling off, affecting the normal use of the work light and posing certain safety hazards. Therefore, how to improve the locking reliability of the battery compartment while maintaining ease of operation has become an urgent technical problem to be solved. Summary of the Invention

[0004] This utility model aims to solve one of the technical problems in related technologies to a certain extent. To this end, this utility model proposes a tail cover locking device, which adds a rotatable locking element to the push-button switch to achieve mechanical obstruction of the switch, preventing the tail cover from being accidentally opened due to accidental contact, thereby improving the ease of operation and enhancing the locking reliability of the battery compartment.

[0005] This utility model embodiment also proposes a work light having the above-mentioned tail cap locking device.

[0006] The technical solution adopted by this utility model is: to provide a tail cover locking device, including a lamp body and a tail cover, wherein the tail cover is connected to one side of the lamp body through a hinge structure, and a push switch is provided on the other side of the lamp body, wherein the push switch is used to control the locking and unlocking of the tail cover;

[0007] A locking member is provided on the lamp body on the same side as the push switch. The locking member can rotate and switch between a locked position and an unlocked position relative to the lamp body.

[0008] In the locked position, the locking member includes a wedge portion that moves into the bottom of the push switch to prevent the push switch from being accidentally activated.

[0009] In the unlocked position, the wedge-shaped part disengages from the bottom of the push switch and is exposed outside the lamp body, allowing the push switch to move freely and enabling the tail cover to unlock normally.

[0010] With the above structure, the work light not only allows for convenient opening of the battery compartment but also significantly improves the locking reliability of the tail cover. Specifically, the locking mechanism, through its rotatable design, allows the wedge to be securely moved into the bottom of the push-button switch after the user completes the locking operation, thus forming a mechanical barrier to prevent external forces from directly acting on the push-button switch. This "secondary protection" mechanism effectively avoids accidental opening of the tail cover due to accidental touch, drops, or squeezing.

[0011] Meanwhile, since the locking component is exposed in the unlocked state, users can intuitively determine whether the device is currently openable, improving the recognizability and safety of the operation. Furthermore, the rotating switching mechanism of the locking component makes the structure more compact in terms of space utilization, facilitating integration and upgrades into existing work light structures without requiring significant adjustments to the overall shape, thus possessing good versatility and promotional value.

[0012] According to one embodiment of the present invention, the locking member is provided with a resiliently installed positioning bead, and the lamp body is provided with at least one positioning groove for cooperating with the positioning bead to limit the position of the locking member; forming a stable positioning state, which not only avoids the locking member from loosening due to vibration or misoperation, but also provides the user with clear tactile feedback, which helps to quickly confirm that the locking member is in the locked or unlocked position, thereby further improving the reliability and ease of use of the device.

[0013] According to one embodiment of the present invention, one of the positioning grooves is disposed at the locking position of the locking member. When the locking member is in the locking position, the positioning bead is elastically embedded in the positioning groove to maintain the locking state.

[0014] According to one embodiment of the present invention, one of the positioning grooves is disposed at the unlocking position of the locking member. When the locking member is in the unlocking position, the positioning bead is elastically embedded in the positioning groove to maintain the unlocked state, forming a clear mechanical positioning, preventing the locking member from disengaging from the locking state due to external force shaking or vibration, ensuring that the tail cover always remains closed during use, and improving the stability and safety of the overall structure.

[0015] According to one embodiment of the present invention, the tail cover is provided with an trunnion, which is used to be hinged to the lamp body to realize the opening and closing of the tail cover.

[0016] According to one embodiment of the present invention, a buffer is provided on the lamp body, and the trunnion contacts the buffer during the rotation of the tail cover. The buffer is made of soft rubber material, preferably flexible materials such as silicone, thermoplastic elastomer (TPE) or ethylene-vinyl acetate copolymer (EVA). Such materials have good elastic recovery performance and aging resistance, which can not only effectively absorb the impact force during the rotation process, reduce noise and friction, but also adapt to temperature changes and long-term use requirements in various working environments.

[0017] According to one embodiment of the present invention, the push switch has a slanted opening structure. When the locking member is in the unlocked position, part of the structure of the locking member is exposed to the outside of the lamp body through the slanted opening. Users can intuitively judge the current state of the locking member by observing the exposed part.

[0018] According to one embodiment of the present invention, the tail cap is provided with a magnetic attracting element for magnetically attracting the lamp body to the metal surface.

[0019] According to one embodiment of the present invention, a first light source is provided at one end of the lamp body, preferably a focused light source, so that the lamp body can be used as a flashlight; and / or

[0020] One side of the lamp body is equipped with a second light source and / or a third light source. The second or third light source can be a focused light source or a diffused light source, depending on the application requirements. A focused light source is suitable for work environments requiring long-distance or concentrated lighting, such as exploration and search; while a diffused light source is suitable for short-distance or large-area lighting, such as equipment maintenance or camp lighting. Through the combination of different types of light sources, the work lamp can flexibly switch lighting modes in different scenarios, enhancing its multi-functional adaptability and practicality.

Example 1

[0048] As shown in Figures 1-9, this embodiment discloses a tail cover 2 locking device, including a lamp body 1 and a tail cover 2. The tail cover 2 is connected to one side of the lamp body 1 through a hinge structure. The other side of the lamp body 1 is provided with a push switch 3, which is used to control the locking and unlocking of the tail cover 2.

[0049] A locking member 4 is provided on the lamp body 1 at the same side as the push switch 3. The locking member 4 can rotate and switch between a locked position and an unlocked position relative to the lamp body 1.

[0050] In the locked position, the wedge portion 4a of the locking member 4 moves into the bottom of the push switch 3 to prevent the push switch 3 from being accidentally activated.

[0051] In the unlocked position, the wedge 4a disengages from the bottom of the push switch 3 and is exposed outside the lamp body 1, allowing the push switch 3 to move freely and enabling the tail cover 2 to be unlocked normally.

[0052] Referring to Figures 1 and 2, in this embodiment, one end of the lamp body 1 is provided with a first light source 1a. The first light source 1a is a focused light source, which can achieve a strong directional lighting effect, thus enabling the lamp body 1 to have the basic function of a flashlight and be suitable for long-distance lighting scenarios. The other end of the lamp body 1 is provided with a tail cap 2. One side of the tail cap 2 protrudes to form a trunnion 21a. The trunnion 21a is rotatably connected to the lamp body 1 through a hinge shaft 25, realizing the opening and closing function of the tail cap 2. The other side of the tail cap 2 is provided with a locking tongue 27, which is used to cooperate with the hook part 3a on the push switch 3 to achieve locking.

[0053] A push-button switch 3 is located on the side opposite the rotatable connection point between the lamp body 1 and the tail cover 2. The push-button switch 3 is pivotally connected to the lamp body 1 via a rotating shaft 7, allowing it to swing around the shaft, thus forming a lever structure. To prevent the rotating shaft 7 from rotating relative to the lamp body 1 during use, the rotating shaft 7 is equipped with a spline 7a structure, achieving torsional positioning between the rotating shaft 7 and the lamp body 1. The front end of the push-button switch 3 has a hook portion 3a for engaging with the locking tongue 27 of the tail cover 2, and the rear end has an actuating portion 3b. The user can press the actuating portion 3b to cause the hook portion 3a to tilt upwards, thereby releasing the engagement with the locking tongue 27.

[0054] A spring 8 is installed between the push-button switch 3 and the lamp body 1. The spring 8 provides an upward elastic force, keeping the actuating part 3b in a naturally upward state without external force, thereby pressing down the latch part 3a and locking the tail cover 2. Only when the user presses the actuating part 3b will the latch part 3a tilt upward and release the locking tongue 27, unlocking the tail cover 2, thus effectively preventing the tail cover 2 from being accidentally opened when not in operation.

[0055] To further improve ease of operation and anti-slip performance, the surface of the push switch 3 is provided with multiple anti-slip protrusions 3c, enhancing the stability of operation for users' fingers in wet or gloved conditions. Additionally, one side of the push switch 3 is provided with a slanted 3d structure (i.e., an angled opening) to complement the visual and operational indication function of the locking element 4.

[0056] The locking component 4 has a cylindrical inner hole 4c inside. A connecting shaft 5 is provided on the lamp body 1. The connecting shaft 5 passes through the inner hole 4c of the locking component 4 and is fixedly connected to the lamp body 1. The connecting shaft 5 and the inner hole 4c are rotatably engaged, and at the same time, the locking component 4 is limited in the axial direction to prevent the locking component 4 from completely disengaging from the connecting shaft 5, thereby preventing the locking component 4 from accidentally loosening and causing the push switch 3 to disengage from the lamp body 1. One side of the outer periphery of the locking component 4 extends outward to form a wedge part 4a, which is used to insert into the gap below the push switch 3 to restrict its movement; the other side is provided with a toggle part 4b, which allows the user to manually rotate the locking component 4 to switch its position.

[0057] In the unlocked position, the wedge 4a can freely move into or out of the gap area below the action part 3b of the push switch 3, realizing the switching of the locking member 4 between the "locked position" and the "unlocked position". When the locking member 4 is rotated to the locked position, the wedge 4a is inserted into the bottom gap of the push switch 3, restricting the action part 3b from moving downward, thereby preventing the hook part 3a from tilting upward and keeping the tail cover 2 locked. When the locking member 4 is rotated to the unlocked position, the wedge 4a is disengaged, releasing the swing space of the action part 3b, allowing the user to press the action part 3b normally to complete the unlocking operation and open the tail cover 2.

[0058] Specifically, referring to Figures 8-9, the locking member 4 is provided with a resiliently mounted positioning bead 6, and the lamp body 1 is provided with two positioning grooves 1d, which cooperate with the positioning bead 6 to limit the position of the locking member 4. One positioning groove 1d is located at the locked position of the locking member 4. When the locking member 4 is in the locked position, the positioning bead 6 is resiliently embedded in the positioning groove 1d to maintain the locked state. The other positioning groove 1d is located at the unlocked position of the locking member 4. When the locking member 4 is in the unlocked position, the positioning bead 6 is resiliently embedded in the positioning groove 1d to maintain the unlocked state.

[0059] Furthermore, in this embodiment, the bottom of the locking member 4 is provided with a mounting groove 4d for accommodating the positioning structure, and the positioning bead 6 is slidably disposed in the mounting groove 4d. An elastic element, such as a spring 8 or an elastic rubber rod, is provided between the bottom of the mounting groove 4d and the positioning bead 6. This elastic element has good compression and recovery properties and can continuously push the positioning bead 6 upward, keeping it in an outward-protruding state and tightly attached to the surface of the lamp body 1.

[0060] With this structural design, when the locking member 4 rotates to different operating positions (such as the locking position or the unlocking position), the positioning bead 6 is automatically embedded in the corresponding positioning groove 1d preset on the lamp body 1 under the action of the elastic member, thereby reliably limiting the rotation position of the locking member 4, preventing it from being accidentally offset due to external force or vibration, and improving the operational stability and positioning accuracy of the entire device.

[0061] Specifically, as shown in Figure 7, in this embodiment, a buffer 9 is provided on the lamp body 1. The trunnion 21a contacts the buffer 9 during the rotation of the tail cover 2. The buffer 9 is made of soft rubber material, preferably flexible materials such as silicone, thermoplastic elastomer (TPE) or ethylene-vinyl acetate copolymer (EVA).

[0062] Furthermore, in this embodiment, both the lamp body 1 and the tail cap 2 are made of aluminum alloy to ensure the overall structure is lightweight and durable. However, since direct contact between aluminum alloys may cause friction and wear or generate noise, a buffer 9 is provided on the lamp body 1 to mitigate the mechanical impact during the rotation of the tail cap 2.

[0063] The buffer 9 includes an embedded portion 9a that is inserted into the lamp body 1. The outer surface of the embedded portion 9a has a beveled surface 9b structure that matches the rotation trajectory of the tail cover 2. When the tail cover 2 rotates around the hinge axis 25, its trunnion 21a continuously contacts the beveled surface 9b, thereby effectively preventing hard impacts between the trunnion 21a and the lamp body 1. This structure not only extends the service life of the component but also improves the smoothness and quietness of the tail cover 2's opening and closing process. Specifically, the push switch 3 has a beveled opening 3d structure. When the locking member 4 is in the unlocked position, part of the structure of the locking member 4 is exposed on the outside of the lamp body 1 through the beveled opening 3d. The user can visually judge the current state of the locking member 4 by observing the exposed part.

[0064] Specifically, as shown in Figure 6, the tail cap 2 is provided with a magnetic suction element 24 for magnetically adsorbing the lamp body 1 onto the metal surface.

[0065] Furthermore, in this embodiment, the tail cover 2 includes a cover body 21, a mounting plate 22, and a cover plate 23. The trunnion 21a is integrally formed on one side of the cover body 21 and serves as a pivot structure for hinged connection between the tail cover 2 and the lamp body 1, realizing the opening and closing action of the tail cover 2; while the other side of the cover body 21 is integrally formed with a locking tongue 27, which is used to cooperate with the hook part 3a of the push switch 3 to realize the locking function of the tail cover 2.

[0066] Mounting plate 22 is installed on the inner side of cover 21, on which electrode plates 26 can be fixedly mounted. Electrode plates 26 are used to establish a reliable electrical connection with the power circuit inside lamp body 1 to ensure stable battery power supply. Meanwhile, cover plate 23 is fixedly installed on the outer side of cover 21, serving both structural protection and aesthetic purposes. Magnetic suction component 24 is disposed between cover 21 and cover plate 23, and is fixed to both by embedding. Magnetic suction component 24 is used to attract the work lamp to ferrous or other metal surfaces, allowing users to fix it without holding it during use, improving operational convenience and safety.

[0067] Specifically, the lamp body 1 is provided with a second light source 1b and a third light source 1c on one side. The second light source 1b is a focused light source, and the third light source 1c is a diffused light source. The focused light source is suitable for working environments that require long-distance lighting or concentrated lighting, while the diffused light source is suitable for short-distance lighting or large-area lighting.

[0068] In another embodiment, a working light is disclosed, including the tail cover 2 locking device described in this embodiment.
