Description

[Technical Field]

[0001] The present invention relates to a battery cover assembly and a separate fusion sight. [Background technology]

[0002] The Chinese patent with patent number CN202223132354.0 discloses a separate-type fusion sight, which is configured by dividing the thermal imaging sight disclosed in the patent application with patent number CN202210970881.4 into two parts: a sighting assembly and an eyepiece assembly, and further completing the circuit connection and signal transmission of these two parts using PCB wiring junction technology, or separately supplying power to both parts and transmitting signals through a wireless communication module, making the use and maintenance of the thermal imaging red-dot sight (Red-Dot Scope Instructions) more convenient.

[0003] The patent states that the fixed connection between the aiming assembly and the main body of the sight is achieved by an engagement groove provided in front of the connecting base of the aiming assembly of the main body of the sight, an engagement base provided in the rear, an engagement block in the engagement groove, and a vertical screw. This type of connection, especially the method of connecting the lens end of the aiming assembly with a vertical screw, necessarily requires space for the screw hole to be reserved in advance, which occupies installation space and squeezes the radial space of the lens assembly, affecting the radial dimension of the lens and making it unfavorable for expanding the aiming assembly.

[0004] In addition, in the conventional battery cover assembly, the negative electrode plate inside the cover plate and the compression spring on the negative electrode plate serve as the negative electrode of the power supply, and the negative electrodes of other parts of the circuit in the entire product must be separately provided as negative electrodes of the power supply, which inevitably increases design and processing costs.In addition, the conventional battery cover plate and battery box are screwed together with connecting bolts, which can become loose due to vibration during long-term use.

DETAILED DESCRIPTION OF THE INVENTION

[0015] In order to further describe the technical means adopted by the present invention to achieve the specified objects and the effects thereof, the following detailed description will be given of specific embodiments, structural features and effects of the present invention in combination with drawings and examples.

[0016] The following provides a clear and complete description of the technical solutions of the embodiments of the present invention with reference to the drawings of the embodiments of the present invention, but it is clear that the described embodiments are only some of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of the present invention.

[0017] In describing the present invention, the directions and positional relationships indicated by terms such as "center," "top," "bottom," "front," "back," "left," "right," "vertical," "horizontal," "align," "overlap," "bottom," "inside," and "outside" are based on the directions and positional relationships shown in the drawings and are used only to facilitate and simplify the description of the present invention, and are not intended to indicate or imply that the devices or elements referred to have a particular orientation or must be constructed or operated in a particular orientation, and therefore should not be construed as limiting the present invention.

[0018] It should be understood that the terms "first" and "second" are used for descriptive purposes only and do not denote or imply relative importance or the number of the indicated technical features. Thus, features defined as "first" and "second" may explicitly or implicitly include one or more of such features, and in the description of this invention, unless otherwise specified, "plurality" means two or more.

[0019] FIG. 1 shows a battery cover assembly including a cover plate 1, a negative electrode conductive plate 2 provided inside the cover plate 1, and a conductive compression spring 3 fixed to both ends of the negative electrode conductive plate 2. The battery cover assembly further includes a conductive piece 4 fixed to an intermediate position inside the negative electrode conductive plate 2 shown in FIG. 3. The conductive piece 4 is fastened to the negative electrode conductive plate 2 by two screws 5 provided on the same vertical line. An upper positioning spring plunger conductive pin 29 and a lower positioning spring plunger conductive pin 30 are provided between the two screws 5 and a front and rear battery box 27 and 28 shown in FIG. 8. 30 corresponds one-to-one, it is electrically connected to the battery negative pole by the conductive piece 4 and conductive compression spring 3, and further the upper positioning spring plunger conductive pin 29 and the lower positioning spring plunger conductive pin 30 electrically connect the power supply negative pole to the housing of the separate fusion sight, so that the entire housing becomes the power supply negative pole. When designing the circuit, the negative pole of any circuit plate can be connected to the adjacent housing, eliminating the need to pull out a separate negative pole lead as in the past. This simplifies and facilitates the design of the entire product circuit, especially the negative pole line.

[0020] 2, 3, and 4, a clamping assembly is provided at one end of the cover plate 1, and the clamping assembly includes a screw 6 passing through the cover plate 1, a fixed base 7 disposed outside the cover plate 1 and fixed to the outer end of the screw 6, and a support base 8 and a handle piece 9 provided on the outside of the fixed base 7. The support base 8 is fixed to the end side of one end of the cover plate 1 on the fixed base 7, and the base end of the handle piece 9 is connected to the other end of the support base 8, i.e., the end on the viewer's left hand side as shown in FIG. 4, by a rotation shaft 16. A groove 10 for accommodating the base end of the handle piece 9 is provided on the outer surface of the fixed base 7. In order to enhance the effect of preventing the screw 6 from loosening, a radially extending through hole 11 is opened in the support base 8, and a steel ball 12, a coil spring 13, and a plug screw 14 are sequentially installed in the through hole 11 from one side of the handle piece 9 to the other. The base end surface of the handle piece 9 is provided with a first spherical recess 1 as shown in FIG. 5. 50, and a second spherical recess 151 is provided on the outer surface of the base end of the handle piece 9, with the opening of the first spherical recess 150 facing the through-hole 11. When the handle piece 9 is in the folded state, i.e., when it is left parallel to the cover plate 1, the steel ball 12 is pressed into the first spherical recess 150 by the coil spring 13 to limit the position of the handle piece 9, and when the handle piece 9 is in the open state, i.e., when its plate surface is perpendicular to the cover plate 1, the steel ball 12 is pressed into the second spherical recess 151 by the coil spring 13 to limit the position of the handle piece 9. The position limiting functions of the steel ball 12, coil spring 13, and first and second spherical recesses 150, 151 serve to limit the rotation of the handle piece 9 along the rotation axis 16.

[0021] As is clear from Figure 3, the inner surface of the fixed base 7 is provided with a plurality of hemispherical bumps 43 uniformly arranged in the circumferential direction, and the cover plate 1 is provided with spherical recesses corresponding to the hemispherical bumps 43. This structure produces a locking sound when the handle piece 9 is turned, contributing to preventing the screws from loosening and allowing the user to know how many times they have been tightened by the number of sounds, preventing damage to the screws due to overtightening. Furthermore, this also functions to limit the rotation of the screw 6, preventing it from turning due to vibration, thereby achieving the purpose of preventing the screw 6 from loosening and effectively preventing the battery cover from loosening.

[0022] Finally, it should be noted that the screw 6 provided in this embodiment includes a threaded portion that passes through the threaded hole in the cover plate 1 and reaches the inside of the cover plate 1, and a rod portion (i.e., a smooth cylinder without threads) that is located on the outside of the cover plate 1 and fixedly connected to the handle piece 9, thereby preventing the screw 6 from falling out of the cover plate 1 after it escapes from the threaded hole 45 on the side of the battery box 15 shown in Figure 8.

[0023] 6 and 7 show a separate-type fusion sight, which includes an internal red dot sight 19 equipped with a reflective aiming optical system, and an aiming assembly 20 (also referred to as a fusion camera assembly in this embodiment; the name of the aiming assembly is reserved mainly for reference to the patent application with patent application number CN202210970881.4 cited in the background art) fixed on the upper surface of the internal red dot sight 19. 7, the rear end of the housing is fixed to the top surface of the internal dot sight 19 by a vertical screw 23, and the bottom of both sides of the front end of the housing are provided with screw holes extending outward and downward, respectively, which are screwed to oblique pull screws 24 provided on both sides of the top surface of the housing of the internal dot sight 19, sloping from bottom to top on the outside. As can be seen from FIG. 8, the box opening of the battery box 15 located below the reflex aiming optical system in the internal dot sight 19 is connected to the battery cover assembly 26 by a connecting shaft 25, that is, the cover plate 1 of the battery cover assembly is rotatably connected to the housing on the rear side of the battery box 15 by the connecting shaft 25.

[0024] The battery box 15 includes a front compartment 27 and a rear compartment 28 arranged side by side. Between the front compartment 27 and the rear compartment 28, two upper positioning spring plunger conductive pins 29 and a lower positioning spring plunger conductive pin 30 are arranged, one above the other. The upper positioning spring plunger conductive pin 29 and the lower positioning spring plunger conductive pin 30 each correspond to a screw 5 shown in Figure 3, and are thereby electrically connected to the battery negative terminal by the conductive piece 4 and conductive compression spring 3. As a result, the aiming assembly and the housing of the internal red dot sight both become the negative terminal of the power supply, which greatly simplifies the design of the negative terminal in the circuit board and improves the reliability of the entire product.

[0025] The outer ends of the upper positioning spring plunger conductive pin 29 and the lower positioning spring plunger conductive pin 30 shown in FIG. 8 are respectively covered with conductive caps 31, which increase the conductive contact area with the screw 5, reduce the conductive resistivity, and ensure the stability of the conductivity.

[0026] Figure 9 is a schematic diagram of the structure of the aiming assembly, in which the low-light night vision lens 32 and low-light night vision chip 33 of the low-light night vision aiming assembly 21 are arranged on one side of the housing along the axial direction, and the thermal imaging lens 34 and thermal imaging perception chip 35 of the thermal imaging aiming assembly 22 are arranged on the other side of the housing along the axial direction. A data processor 36 is provided within the housing, connected to the low-light night vision chip 33 and the thermal imaging perception chip 35, respectively. The data processor 36 is connected to an interface circuit plate 38 provided on the top surface of the internal red dot sight 19 by a circuit adapter plate 37 (sealed within the housing by a bottom cover 42) provided on the bottom surface of the housing. A circuit board 39 and a control key mechanism 40 arranged on the outside of the circuit board 39 are provided at the rear end of the housing, and a control key assembly 41 is provided on the top surface of the housing.

[0027] In this embodiment, the oblique pull screw 24 is used to fix the aiming assembly from an obliquely downward direction, which effectively avoids the radial space occupied by the aiming assembly due to the vertical screw fixing method in the prior art. [Explanation of symbols]
