Description

Technical Field

[0001] The utility model relates to the technical field of lighting equipment, in particular to a tail cap assembly and a flashlight. Background Art

[0002] Generally, the switch of a tactical flashlight is arranged at the tail of the flashlight so that the switch can be quickly and accurately operated in an emergency without having to find the switch position in a dark environment. Also, to meet the functional requirements, multiple switches are usually arranged at the tail of the flashlight, including a main switch and one or more sub-switches. The main switch is only used to turn on or off the flashlight, and the sub-switch realizes functions such as flashlight mode conversion or brightness adjustment.

[0003] There are generally two ways for existing flashlights with multiple switches at the tail. One is to arrange the main switch and the sub-switches side by side, distinguished by different shapes and sizes (taking CN217521877U and CN202425135U as examples); the other is that the main switch is in the center, and the annular sub-switch surrounds the main switch (taking CN109506145A as an example), or multiple sub-switches are arranged around the periphery of the main switch to increase the operation angle (taking CN107642706A as an example), so as to quickly and accurately find the sub-switch for operation in a dark environment.

[0004] However, the above existing technologies all have certain deficiencies. Among them, in the first way, it is impossible to quickly and accurately find the sub-switch in the dark. When taking out the flashlight from the pocket quickly in an emergency, the angle of the sub-switch may deviate from the pressing direction of the user's thumb, and the sub-switch needs to be found first before operation, which is not conducive to use in an emergency. Although the second way can shorten the time to find the sub-switch in the dark to a certain extent, increasing the number and area of the sub-switches on the limited tail cap area will result in too small main and sub-switch buttons, or too small gaps between the main and sub-switches, and it is not easy to accurately press the corresponding switch during actual use, especially when operating with gloves, and even misoperation may occur. Summary of the Utility Model

[0005] The utility model overcomes the above-mentioned drawbacks and provides a tail cap assembly and a flashlight with a simple structure and precise control.

[0006] The technical solution adopted by the utility model to solve its technical problems is: a tail cap assembly, including a tail cap and a main switch arranged at the end of the tail cap, further including a sub-switch, and a positioning platform protruding from the outer side wall of the tail cap, and the sub-switch is installed on the end face or side face of the positioning platform.

[0007] Further, it may also include a positioning ring, the positioning ring is fixedly installed on the outer side wall of the tail cap, and the plane where the positioning ring is located forms an angle of less than ±25° with the axis of the tail cap.

[0008] Further, the plane where the positioning ring is located may be parallel to the axis of the end cap.

[0009] Further, the positioning ring may further have a fixing collar, and the positioning ring is fixed to the outer side wall of the end cap by sleeving the outer side wall of the end cap with the fixing collar.

[0010] Further, at least one positioning notch may be provided on the circumference of the fixing collar, and the positioning notch corresponds to the positioning platform.

[0011] Further, there may be two positioning notches, which are arranged axially symmetrically with respect to the plane where the positioning ring is located.

[0012] Further, the positioning ring may be a closed O-ring or a semi-open C-ring.

[0013] Further, the included angle between the position where the positioning platform is located and the position where the positioning ring is located on the circumference of the end cap may be between ±30° and 120°.

[0014] A flashlight includes a barrel body and an end cap assembly as described in any one of the above.

[0015] In the present utility model, a secondary switch is provided at the positioning platform protruding from the outer side wall of the end cap. Since the positioning platform has an obvious feel, the position of the secondary switch can be quickly located. Further, the positioning ring fixedly installed on the outer side wall of the end cap can have the index finger inserted into the positioning ring when the flashlight is taken. Utilizing the natural structure of the human finger, the thumb can press the secondary switch immediately for quick operation. Even in a dark environment, the flashlight can be quickly and accurately controlled, and there will be no associated pressing and thus no misoperation, simply and effectively solving the problems of the prior art.

[0020] As inFigure 1 As shown in the figure, it is an exploded schematic view of a flashlight of a preferred embodiment of the present utility model. The flashlight includes a barrel body 6 and a tail cap assembly. The tail cap assembly includes a tail cap 1 and a main switch 2 provided at the end of the tail cap 1. A positioning platform 31 protrudes from the outer wall of the tail cap 1, and a secondary switch 3 is installed on the end face of the positioning platform 31.

[0021] Among them, the main switch 2 further includes a main switch board, a key switch, a pressing cap, etc. (not marked in the figure). Among them, components such as the circuit board and the key switch are placed in the hollow interior of the flashlight tail cap 1. The pressing cap covers the key switch and protrudes from the end of the flashlight tail cap 1 and is arranged in the center. The secondary switch 3 also includes components such as a secondary switch board, a key switch, and a pressing cap. Inside the tail cap 1, the main switch board and the secondary switch board are electrically connected through a wire to conduct control signals. The secondary switch 3 is installed in the positioning platform 31, and the key switch is covered by the pressing cap and protrudes from the end face of the positioning platform 31. The main switch and the secondary switch can adopt existing push-button switches, and their internal structures will not be elaborated here. Moreover, any switch with an existing or future structure is within the protection scope of the present utility model.

[0022] This preferred embodiment also includes a positioning ring 4. When grasping the flashlight, the index finger is inserted into the positioning ring 4. The positioning ring 4 has a fixed collar 5. The fixed collar 5 is sleeved on the outer wall of the tail cap 1 to fix the positioning ring 4 to the tail cap 1. The plane where the positioning ring 4 is located is parallel to or even coincides with the axis of the tail cap 1, that is, the included angle between the two is 0°. When holding the barrel body 6 of the flashlight with the palm, the index finger can conveniently pass through the positioning ring 4 directly. In addition, according to the structure of different flashlights and the individual usage habits of users, the positioning ring 4 can be slightly inclined, that is, the plane where the positioning ring 4 is located can have a small included angle with the axis of the tail cap 1, usually an included angle less than ±25°, making it more comfortable for the user to hold.

[0023] Two U-shaped positioning notches 51 are provided on the circumference of the fixed collar 5. The positioning notches 51 correspond to the positioning platform 31, so that the fixed collar 5 will not rotate after being installed on the tail cap 1. The two positioning notches 51 are arranged axially symmetrically with respect to the plane where the positioning ring 4 is located, and the usage direction of the positioning ring 4 can be adjusted according to the needs of left- or right-handed use. When the needs of left- or right-handed use are not considered, only one positioning notch 51 can also be provided. In addition, on the side of the barrel body 6 facing the tail cap assembly, a ring-shaped edge 61 can be provided. The inner diameter of the ring-shaped edge 61 is adapted to the outer diameter of the end of the flashlight barrel body. Through the combined action of the positioning platform 31 and the ring-shaped edge 31, the fixed collar 5 is fixed between the barrel body 6 and the tail cap 1.

[0024] As Figure 2As shown, it is a combined schematic diagram of this preferred embodiment. Figure 3 is Figure 2 the top view of. Combining Figure 1 , Figure 2 , Figure 3 it can be known that when installing the flashlight, the fixed collar 5 is sleeved on the outside of the tail cap 1. According to the needs of left - hand or right - hand use, the positioning notch 51 is stuck at the positioning platform 31 with a shape adapted thereto, so that the fixed collar 5 and the positioning ring 4 will not rotate relative to the tail cap 1. Then the positioning ring 4 and the tail cap 1 are installed on the flashlight barrel 6 together. When in use, when a right - handed user takes out the flashlight from the pocket, first insert the index finger into the positioning ring 4 to directly position the orientation of the flashlight. At this time, the thumb can press the main switch 2 on the tail cap 1 of the flashlight. At the same time, the thumb can also be translated to the left in the dark to press the secondary switch 3 to achieve the corresponding conversion or adjustment operation, without having to search for the switch position, realizing fast and accurate operation. On the contrary, when a left - handed user installs, the positioning notch 51 on the other side of the fixed collar 5 is aligned with the positioning platform 31 and stuck at the positioning platform 31 with a shape adapted thereto. Then the positioning ring 4 and the tail cap 1 are installed on the flashlight barrel 6 together. When in use, when a left - handed user takes out the flashlight, first insert the index finger into the positioning ring 4, and the thumb can press the main switch 2. When the thumb is translated to the right, the secondary switch 3 can be pressed. Figure 2 What is shown is the installation method of the flashlight for a left - handed user.

[0025] In addition, the secondary switch 3 can also be installed on the side of the positioning platform 31, and the index finger passing through the positioning ring 4 can be used to press the secondary switch located on the side of the positioning platform 31, which is also a preferred implementation method.

[0026] As Figure 3 shown, the positional relationship between the positioning ring 4 and the positioning platform 31 can be reasonably set based on ergonomics according to operation and use needs, so that the thumb or index finger is in a comfortable pressing position for finger operation. The included angle between the position where the positioning platform 31 is located and the position where the positioning ring 4 is located on the circumference of the tail cap 1, that is, the included angle between OB and OA, can be arbitrarily selected and changed. Usually, the included angle is between ±30° and 120°, meeting the more comfortable use needs of different users. In this preferred embodiment, the position where the positioning platform 31 is located and the position where the positioning ring 4 is located are perpendicular to each other, that is, the included angle between OB and OA is 90°.

[0027] As a simplification of this preferred embodiment, the fixed collar 5 can be sleeved on the outer side of the end cap 1 by interference fit to fix the positioning finger ring 4 and the end cap 1, and the positioning notch 51 does not need to be provided. As a further simplification of this preferred embodiment, in the case of not installing the positioning finger ring 4, since the positioning platform 31 itself protrudes from the side wall of the end cap 1, its feel is obvious, and the position of the secondary switch 3 can also be quickly positioned.

[0028] In this preferred embodiment, the positioning finger ring 4 is a closed O-ring. When the user temporarily does not use the flashlight and operates other equipment, the positioning finger ring 4 can still be sleeved on the finger, and the flashlight is rotated outside the palm. After the operation is completed, the flashlight is rotated back into the palm, avoiding the cumbersome operation of repeatedly putting down and picking up the flashlight. In addition, the positioning ring can also be a semi-open C-ring. During operation, the index finger is placed at the arc surface of the C-ring, and the orientation of the flashlight can be positioned, and the purpose of quick and accurate operation can also be achieved.

[0029] In the present invention, unless otherwise clearly defined and limited, terms such as "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be directly connected, or indirectly connected through an intermediate medium, and can be the internal communication of two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0030] The above has introduced in detail a kind of end cap assembly and flashlight provided by the present invention. Specific examples are used in this article to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope.
