Abstract
Description
Technical Field
[0001] This invention belongs to the field of optical instrument technology, and in particular relates to a target observation mirror. Background Technology
[0002] Currently, conventional optical instruments typically use a threaded structure for the battery cover to securely connect the positive and negative terminals of the battery compartment to the battery. While this threaded structure is simple, reliable, and shock-resistant, the long screw-in stroke requires users to repeatedly unscrew the cover to open the battery compartment before replacing the battery. This hinders quick battery changes. However, observational optical instruments like target scopes often do not require high shock resistance and need quick battery replacements. A threaded structure would result in low operational efficiency. Therefore, it is necessary to design a structure for observational optical instruments like target scopes that not only ensures a stable connection between the positive and negative terminals of the battery compartment but also allows users to quickly open the battery compartment for replacement, thereby improving the user experience. Summary of the Invention
[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a target observation lens with a short screw-in stroke between the cover and the cylinder in a battery tube and high operating efficiency.
[0004] The present invention is implemented as follows: A target observation mirror includes: a mirror body, wherein the mirror body is provided with an optical system, a power module and a battery cylinder, the battery cylinder includes a cover, a cylinder and a circuit board assembly, the cover includes at least one radial protrusion around its central axis and disposed on its outer periphery, the cylinder includes at least one sliding engagement structure disposed at any end of the cylinder and used to cooperate with the radial protrusion, the sliding engagement structure being provided with a clearance groove, a spiral groove communicating with the clearance groove and a stop groove extending upward from the end of the spiral groove in sequence on the sliding path of the radial protrusion, the cylinder also includes a battery compartment for accommodating a battery, the circuit board assembly is connected to the other end of the cylinder and supports any electrode of the battery installed in the battery compartment, a first elastic member fixedly connected to the bottom of the cover abuts against the other electrode of the battery, which is used to press the battery and push the radial protrusion into the stop groove, and together with the stop groove, limits the degree of freedom of the radial protrusion.
[0005] In one optional embodiment, the cylinder is symmetrically provided with two sliding fit structures, namely a first sliding fit structure and a second sliding fit structure, and the radial protrusion includes a first boss and a second boss integrally formed with the cover.
[0006] In an optional embodiment, the cylindrical body is symmetrically provided with two sliding fit structures, namely a first sliding fit structure and a second sliding fit structure, and the cover body is also provided with a blind hole, and the radial protrusion includes a first boss and a second boss that are respectively fixedly connected to the blind hole.
[0007] In one optional embodiment, the sliding connection ends of the first boss and the second boss that cooperate with the first sliding fit structure and the second sliding fit structure are cylindrical, spherical or conical in shape.
[0008] In an optional embodiment, the clearance groove is disposed on the inner wall of the cylinder and forms a step with the inner wall of the cylinder. The clearance groove provides sufficient space for the cover to move radially into the cylinder until the first boss and the second boss abut against the step.
[0009] In an optional embodiment, the spiral groove extends downward along the wall of the cylinder, and the first boss and the second boss respectively abut against the step and then spiral into the spiral groove along the step, and reach their ends under the guidance of the spiral groove.
[0010] In an optional embodiment, the anti-reverse groove is at an angle to the spiral groove, which is used to prevent the first boss and the second boss from sliding in the opposite direction of the spiral groove. When the first boss and the second boss slide to the end of the spiral groove, the first elastic member abutting against the battery pushes the cover in the opposite direction of its compression direction, and at the same time, the sliding connection end of the first boss and the second boss is locked into the anti-reverse groove.
[0011] In one alternative embodiment, the circuit board assembly includes a second elastic element, a circuit board, and a carrier element, wherein the circuit board is fixedly connected to the carrier element as a central component for controlling the current, and the second elastic element is electrically connected to the circuit board.
[0012] In one alternative embodiment, the first elastic element and the second elastic element are conical helical compression springs or cylindrical helical compression springs. The first elastic element is used to compress the battery and the conductive element, and the second elastic element is used to support the battery and the conductive element.
[0013] In an optional embodiment, a rubber ring is also fitted around the outer periphery of the cover to prevent moisture from entering the cylinder.
[0014] The technical advantage of this invention over the prior art is that the battery cylinder body and battery cover of the existing target observation scope are usually fitted with a threaded structure. However, when replacing the battery, due to the long screwing stroke of the threaded structure, the user needs to twist the battery cover multiple times to unscrew it from the cylinder body, which takes a long time and the user cannot quickly complete the battery replacement. To address this, the present invention provides a target observation mirror. Compared with the prior art, the battery cylinder mounted on the target observation mirror eliminates the need for a screw-on connection between the cover and the cylinder to tighten the battery. Instead, it employs a method of coordinated action between a radial protrusion and a sliding fit structure. The user aligns the radial protrusion on the battery cover assembly with the clearance groove. When the radial protrusion abuts against the step, the user rotates the cover to allow the radial protrusion to slide into the spiral groove. Guided by the spiral groove, the protrusion reaches the end of the spiral groove. After the user releases the force, the first elastic element pushes the cover radially in the opposite direction of its compression direction, causing the radial protrusion to engage with the anti-reverse groove. Similarly, when the battery needs to be replaced, the user presses the cover radially downward along the circumferential axis of the cylinder, causing the radial protrusion to disengage from the anti-reverse groove and enter the spiral groove. The user then rotates the cover in the opposite direction to allow the radial protrusion to enter the clearance groove along the spiral groove, and then removes the cover. The above operation does not require multiple twists of the cover, and due to the absence of thread pitch and other factors, the screwing stroke between the cover and the cylinder is further shortened, making the connection and disassembly of the cover and the cylinder more convenient and the battery replacement more efficient.

Detailed Implementation
[0021] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0022] like Figure 1-4 The diagram shown is a schematic representation of a preferred embodiment of the present invention, illustrating that the target observation scope provided by the present invention includes:
[0023] The scope comprises a scope body 300, an optical system (not shown), a power module 200, and a battery holder 100. The optical system is located inside the scope body and allows the user to aim at distant targets; this is a conventional technology and will not be described in detail here. In this invention, the power module 200 is also located in the scope body 300 and includes a laser module (not shown) for measuring the distance between the target and the user, and a display screen (not shown) for displaying distance information fed back by the laser module. The battery holder 100 is also located in the scope body 300 and is electrically connected to the power module 200. After installing a suitable battery 21, it can provide power to the power module 200.
[0024] This invention provides a different technical solution for the fitting method of the battery cylinder 100 and the cover 10 in existing target observation scopes. The battery cylinder 100 of this invention specifically includes:
[0025] The cylindrical body 1 is a component with a certain geometric shape, and its material can be, but is not limited to, metal. In an optional embodiment, the cylindrical body 1 is cylindrical with a certain length, including a first end 2, a second end 3, and a battery compartment 20. The first end 2 or the second end 3 includes at least one sliding fit structure for cooperating with the radial protrusion. When there are two or more sliding fit structures, the sliding fit structures are evenly distributed on the wall surface of the cylindrical body 1 around the central axis of the cylindrical body 1. The number of sliding fit structures is optimally two. The battery compartment 20 is a cavity with a certain space for installing the adapted battery 21. The other end of the cylindrical body 1 is connected to a circuit board assembly 16 for supporting the battery 21. The shape and size of the sliding fit structure are not limited. It is provided with a relief groove 6, a spiral groove 7, and a stop groove 8 in sequence on the sliding path of the radial protrusion. The spiral groove 6 communicates with the relief groove, and the stop groove 8 is formed by extending upward from the end of the spiral groove 7 and forming a certain angle with the spiral groove 7. In an optional embodiment, there are two sliding fit structures: a first sliding fit structure 4 and a second sliding fit structure 5, which are symmetrically arranged at the first end 2 of the cylinder 1 and have the same shape and size. Specifically, the clearance groove 6 is formed on the inner wall of the cylinder 1 or penetrates the wall surface of the cylinder 1, the spiral groove 7 is formed on the inner wall of the cylinder 1 or penetrates the wall surface of the cylinder 1 and extends spirally downward along the wall surface of the cylinder 1 for a certain length, and the anti-reverse groove 8 is formed by extending upward from the end of the spiral groove 7 for a certain length. The lengths of the spiral groove 7 and the anti-reverse groove 8 can be designed according to actual needs.
[0026] The cover 10 comprises a radial protrusion located on its outer periphery and a first elastic element 14. The radial protrusion works in conjunction with a sliding fit structure, and the first elastic element 14 is fixedly installed at the bottom of the cover 10. The connection method between the radial protrusion and the cover 10 is not limited; it can be integrally formed or fixedly connected. The fixed connection can be, but is not limited to, a threaded fit or a plug-in fit. The sliding connection end of the radial protrusion engaging with the sliding fit structure can be cylindrical, spherical, or conical, and is not limited here. The first elastic element 14 can be, but is not limited to, a conical helical compression spring or a cylindrical helical spring, and is not limited here. In an optional embodiment, a rubber ring 15 is also fitted around the outer periphery of the cover 10 to prevent moisture from entering the cylinder 1.
[0027] In an optional embodiment, the sliding fit structures are a first sliding fit structure 4 and a second sliding fit structure 5 with the same shape and size, and the radial protrusion includes a first boss 11 and a second boss 12 that are slidably connected to the first sliding fit structure 4 and the second sliding fit structure 5, respectively. The first boss 11 and the second boss 12 are fixedly connected to the cover 10. The first boss 11 and the second boss 12 are cylindrical pins with a certain length, which are fixedly connected to the blind hole 13 provided on the outer periphery of the cover 10 through a threaded fit.
[0028] Furthermore, in this embodiment, to avoid weakening the impact resistance of the cylinder 1, the clearance groove 6 does not penetrate the wall of the cylinder 1, and the clearance groove 6 forms a step 22 with the inner wall of the cylinder 1. The step 22 is located at the junction of the spiral groove 7 and the clearance groove 6. The clearance groove 6 provides sufficient space for the cover 10 to move radially into the interior of the cylinder 1 and for the first boss 11 and the second boss 12 to enter the spiral groove 7. The spiral groove 7 penetrates the wall of the cylinder 1, and its groove width is greater than or equal to the size of the first boss 11 and the second boss 12, which is beneficial to the cover 1. The first boss 11 and the second boss 12 are radially inserted into the cylinder 1 until they abut against the step 22. Then, the first boss 11 and the second boss 12 slide along the step 22 into the spiral groove 7. The anti-reverse groove 8 also penetrates the wall of the cylinder 1, and its groove width is greater than or equal to the size of the sliding connection end of the first boss 11 and the second boss 12. This is beneficial for the first elastic member 14, which abuts against the battery 21, to push the battery cover assembly 9 in the opposite direction along its compression direction when the first boss 11 and the second boss 12 slide to the end of the spiral groove 7, and at the same time, the first boss 11 and the second boss 12 are locked into the anti-reverse groove 8.
[0029] The circuit board assembly 16 includes a second elastic element 19, a circuit board 18, and a carrier 17. The carrier 17 is used to fix the circuit board 18 to the other end of the connecting cylinder 1. The circuit board 18 serves as a central component for controlling the current and is electrically connected to the second electrical component. The second elastic element 19 may be, but is not limited to, a conical helical compression spring or a cylindrical helical compression spring. It abuts against any electrode of the battery 21 to support the battery 21 and is responsible for conducting electricity.
[0030] To further illustrate the structural features, technical means employed, and expected technical effects of the present invention, the usage of the preferred embodiment of the present invention is described below:
[0031] The target observation scope provided by this invention includes a battery cylinder 100 mounted on the scope body 300, which comprises two stages during use: closing and opening. In the closing stage, the user aligns the sliding connection ends of the first protrusion 11 and the second protrusion 12 on the cover 10 with the clearance groove 6 and moves radially along the central axis of the cylinder 1 until the first protrusion 11 and the second protrusion 12 abut against the step 22. The user then rotates the cover 10 to allow the first protrusion 11 and the second protrusion 12 to slide into the spiral groove 7 and reach the end of the spiral groove 7 under its guidance. During this process, the first elastic element 14 and the second elastic element 19 are compressed under the action of the battery 21 and the cover 10. After the first protrusion 11 and the second protrusion 12 reach the end of the spiral groove 7, the user releases the pressure. Under the action of the first elastic element 14 and the second elastic element 19 restoring their elastic length, the cover 10 moves radially in the opposite direction of the compression of the first elastic element 14, and drives the first protrusion 11... The first protrusion 11 and the second protrusion 12 engage with the anti-reverse groove 8, thus completing the closing process. In addition, the degrees of freedom of the first protrusion 11 and the second protrusion 12 in each direction are limited by the anti-reverse groove 8 and the first elastic member 14 abutting against the battery 21, thereby ensuring the stability of the connection between the battery 21 and the first elastic member 14 and the second elastic member 19. During the opening process, the user presses the cover 10 radially downward along the central axis of the cylinder 1, causing the cover 10 to move radially downward a certain distance. The purpose is to allow the first protrusion 11 and the second protrusion 12 to engage with the anti-reverse groove 8 and enter the spiral groove 7. Then, the user rotates the cover 10 in the opposite direction, causing the first protrusion 11 and the second protrusion 12 to enter the clearance groove 6 along the spiral groove 7. Then, the user removes the cover 10, thus completing the opening process.
[0032] In the solution provided by the present invention, users can complete the closing or opening process to replace the battery 21 without having to twist the cover 10 multiple times. Furthermore, since there are no limitations such as thread pitch, the screwing formation between the cover 10 and the cylinder 1 is further shortened, making the connection and disassembly of the cover 10 and the cylinder 1 more convenient and the battery replacement efficiency higher.
[0033] The above are merely preferred embodiments of the present invention, and only specifically describe the technical principles of the present invention. These descriptions are only for explaining the principles of the present invention and should not be construed as limiting the scope of protection of the present invention in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention, as well as other specific embodiments of the present invention that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present invention.
