Description

Technical Field

[0001] The present application relates to the field of infrared imaging technology, and in particular to an infrared front-end device and a sighting device. Background Art

[0002] The infrared front device is usually installed at the front end of the gun sight and used in combination with the white light sight in the sight to provide clear infrared images, thereby expanding the night combat capability of weapons and equipment.

[0003] Currently, existing infrared front-end devices have several drawbacks in practical application. They place very high demands on the positioning of the eyepiece and the display screen. Conventional methods involve adjusting the eyepiece. Due to the weight of the eyepiece, the impact of a firearm can affect its precise and stable positioning. The eyepiece can shift during impact, affecting parallax and, consequently, the aiming accuracy of the entire system. Furthermore, the eyepiece is bulky, and the assembly of the eyepiece and its adjustment mechanism further increases the overall size and weight, making adjustment difficult and instability poor. Utility Model Content

[0004] The purpose of this application is to provide an infrared front device, which solves the problems of instability and affected aiming accuracy in eyepiece adjustment in the prior art by adopting a solution for moving and adjusting the display screen assembly, thereby improving the stability and operational convenience of the aiming device.

[0005] Another object of the present application is to provide a sighting device.

[0006] To achieve the above objectives, the present application provides an infrared front-end device, comprising:

[0007] Eyepiece assembly;

[0008] A display screen assembly is provided on the eyepiece assembly, and the display screen assembly can be moved and adjusted relative to the eyepiece assembly; the display screen assembly includes:

[0009] Display screen assembly;

[0010] A mounting ring is sleeved on the display screen assembly, and the mounting ring cooperates with the eyepiece assembly. The mounting ring is used to adjust the cooperation position with the eyepiece assembly to change the relative position of the display screen assembly and the eyepiece assembly.

[0011] In some embodiments, the mounting ring and the eyepiece assembly are engaged through threads, and the rotation of the mounting ring can be converted into a change in the distance of the mounting ring relative to the eyepiece assembly through the threads.

[0012] In some embodiments, the eyepiece assembly is provided with a mounting platform, and the mounting ring is sleeved on the mounting platform and threadedly connected to the mounting platform.

[0013] In some embodiments, the infrared front device further includes:

[0014] A pre-tightening member is provided between the eyepiece assembly and the display screen assembly, and is used to apply a force to the display screen assembly so that the display screen assembly is pressed tightly against the mounting ring.

[0015] In some embodiments, the eyepiece assembly is provided with a mounting platform; the pre-tightening member is provided between the mounting platform and the display screen assembly; and / or,

[0016] The eyepiece assembly is provided with a guide platform; the pre-tightening member is sleeved on the guide platform; and / or,

[0017] The pre-tightening member is made of elastic material.

[0018] In some embodiments, the eyepiece assembly is provided with a guide platform, and the guide platform cooperates with the display screen assembly so that the display screen assembly moves and adjusts under the guidance of the guide platform.

[0019] In some embodiments, the display screen assembly is mounted on the guide platform; and / or,

[0020] The guide platform is provided with a first structure, and the display screen assembly is provided with a second structure. The first structure cooperates with the second structure to achieve movement, adjustment and anti-rotation of the display screen assembly on the guide platform.

[0021] In some embodiments, the display screen assembly includes:

[0022] Mounting seat;

[0023] A display screen, provided on the mounting base;

[0024] Wherein, the mounting ring is sleeved on the mounting seat, and the display screen passes through the mounting ring.

[0025] In some embodiments, the display screen is fixed on the mounting base by gluing; and / or,

[0026] The mounting ring is provided with an operating window communicating with the interior thereof, and the mounting ring is fixed to the eyepiece assembly by gluing through the operating window; and / or,

[0027] The infrared front device also includes a shell, in which the eyepiece assembly and the display screen assembly are arranged.

[0028] The present application also provides a sighting device, comprising a sight and the above-mentioned infrared front device, wherein the infrared front device is arranged on the sight.

[0029] Compared with the above-mentioned background technology, the infrared front device provided in this application mainly includes an eyepiece assembly and a display screen assembly. The display screen assembly is arranged in the eyepiece assembly, and the display screen assembly can be moved and adjusted relative to the eyepiece assembly; the display screen assembly includes a display screen assembly and a mounting ring. The mounting ring is sleeved on the display screen assembly, and the mounting ring cooperates with the eyepiece assembly. The mounting ring is used to adjust the cooperation position with the eyepiece assembly to change the relative position of the display screen assembly and the eyepiece assembly.

[0030] In existing infrared front-end devices, the instability of parallax adjustment and the resulting aiming accuracy issues are primarily due to the weight and bulk of the eyepiece. The eyepiece is subject to significant impact during fire, which can easily cause it to shift position, affecting parallax and aiming accuracy. Furthermore, the eyepiece's bulk and weight increase the overall size and weight of the device, making adjustment complex and inconvenient.

[0031] To address this issue, the infrared front-end device provided in this application employs an innovative solution: precise control of parallax is achieved through the movement and adjustment of the display assembly. Specifically, the display assembly includes a display screen assembly and a mounting ring. The mounting ring cooperates with the eyepiece assembly. By adjusting the relative position of the mounting ring and the eyepiece assembly, the position of the display screen assembly can be changed, thereby adjusting the parallax.

[0032] The advantage of this design is that the display screen assembly is lighter and smaller than the eyepiece assembly, making it easier to achieve precise adjustments while reducing the weight of the entire device. In addition, taking the sight as a reference, the assembly positions from back to front are the sight, eyepiece assembly, and display screen assembly. Since the display screen assembly is located at the outermost position, it is more convenient to adjust, and there is no need for complicated adjustment operations on the eyepiece assembly.

[0033] Combined with the above structure and process description, it can be seen that the infrared front device has at least the following beneficial effects: the infrared front device solves the problems of instability and affected aiming accuracy in eyepiece adjustment in the prior art by adopting a solution for moving and adjusting the display screen assembly, thereby improving the stability and ease of operation of the aiming device.

[0044] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0045] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0046] Please refer to Figures 1 to 3 ,in, Figure 1 This is an exploded view of the infrared front-end device provided in an embodiment of the present application. Figure 2 This is a cross-sectional view of the infrared front-end device provided in an embodiment of the present application. Figure 3 This is an appearance diagram of the infrared front-end device provided in an embodiment of the present application.

[0047] In a first specific embodiment, Figure 1 and Figure 2As shown, the infrared front device 100 provided by the embodiment of the present application mainly includes an eyepiece assembly 1 and a display screen assembly 2. The display screen assembly 2 is arranged on the eyepiece assembly 1, and the display screen assembly 2 can be moved and adjusted relative to the eyepiece assembly 1. Specifically, the display screen assembly 2 moves toward the eyepiece assembly 1, or moves back to the eyepiece assembly 1; the display screen assembly 2 includes a display screen assembly 21 and a mounting ring 22, and the mounting ring 22 is sleeved on the display screen assembly 2, and the mounting ring 22 cooperates with the eyepiece assembly 1. The mounting ring 22 is used to adjust the cooperation position with the eyepiece assembly 1 to change the relative position of the display screen assembly 21 and the eyepiece assembly 1.

[0048] In existing infrared front-end devices 100, the instability of parallax adjustment and the resulting aiming accuracy issues are primarily due to the weight and bulk of the eyepiece. The eyepiece is subject to significant impact during firearm firing, which can easily cause it to shift position, affecting parallax and aiming accuracy. Furthermore, the eyepiece's bulk and weight increase the overall size and weight of the device, making the adjustment process complex and inconvenient.

[0049] To address this issue, the infrared front-end device 100 provided in this application employs an innovative solution, namely, precise control of parallax through the movement and adjustment of the display assembly 2. Specifically, the display assembly 2 includes a display assembly 21 and a mounting ring 22. The mounting ring 22 cooperates with the eyepiece assembly 1. By adjusting the relative position of the mounting ring 22 and the eyepiece assembly 1, the position of the display assembly 21 can be changed, thereby adjusting the parallax.

[0050] The advantage of this design is that the display screen assembly 2 is lighter and smaller than the eyepiece assembly 1, making it easier to achieve precise adjustments while reducing the weight of the entire device. In addition, taking the sight as a reference, the assembly positions from back to front are the sight, eyepiece assembly 1, and display screen assembly 2. Since the display screen assembly 2 is located at the outermost position, it is more convenient to adjust and there is no need to perform complicated adjustment operations on the eyepiece assembly 1.

[0051] In combination with the above structure and process description, it can be seen that the infrared front-end device 100 has at least the following beneficial effects: the infrared front-end device 100 solves the problems of instability and affected aiming accuracy in eyepiece adjustment in the prior art by adopting a solution for moving and adjusting the display screen assembly 2, thereby improving the stability and operational convenience of the aiming device.

[0052] In some embodiments, the mounting ring 22 is threadedly engaged with the eyepiece assembly 1 , and the rotation of the mounting ring 22 can be converted into a change in the distance of the mounting ring 22 relative to the eyepiece assembly 1 through the thread.

[0053] In this embodiment, the engagement between the mounting ring 22 and the eyepiece assembly 1 is achieved through threads, which provides a simple and effective adjustment method. The threaded engagement allows the mounting ring 22 to be precisely moved on the eyepiece assembly 1, and this movement can be achieved through a rotational action.

[0054] Specifically, whether the mounting ring 22 is provided with an internal thread and the eyepiece assembly 1 is provided with an external thread, or the opposite configuration, the rotating mounting ring 22 can move along the axis of the eyepiece assembly 1, thereby changing the relative position between the display screen assembly 21 and the eyepiece assembly 1, thereby achieving parallax adjustment.

[0055] Except for this embodiment, this application does not limit threaded engagement to being the only adjustment method. In addition to threaded engagement, various other engagement methods may be employed to achieve movement and adjustment of the display screen assembly 2, and these methods also fall within the scope of protection of this application. For example, other mechanical engagement methods such as sliding engagement, wedge engagement, and elastic engagement may be employed. As long as these methods can achieve precise movement and adjustment of the display screen assembly 2 relative to the eyepiece assembly 1 to meet the requirements for parallax adjustment, they may be considered part of the technical solution of this application.

[0056] In some embodiments, the eyepiece assembly 1 is provided with a mounting platform 11 , and the mounting ring 22 is sleeved on the mounting platform 11 and threadedly connected to the mounting platform 11 .

[0057] In this embodiment, the eyepiece assembly 1 is designed with a mounting platform 11, which serves to provide a stable mounting position for the mounting ring 22. The mounting ring 22 is designed to fit over the mounting platform 11 and be connected to the mounting platform 11 via threads. This design requires that the mounting platform 11 must be provided with external threads, while the mounting ring 22 must be provided with corresponding internal threads to achieve a threaded connection between the two.

[0058] The advantage of this design is that the mounting ring 22, which fits over the mounting platform 11, not only provides a reliable support point for the display screen assembly 2 but also, through a threaded connection, allows precise adjustment of the display screen assembly 2 relative to the eyepiece assembly 1. Furthermore, because the mounting ring 22 simultaneously covers both the display screen assembly 21 and the mounting platform 11, this structural design enhances overall stability and strength. During firearm use, even when subjected to shock and vibration, the display screen assembly 2 maintains its precise position, ensuring parallax stability and aiming accuracy.

[0059] In some embodiments, the infrared front-end device 100 further includes:

[0060] The pre-tightening member 3 is provided between the eyepiece assembly 1 and the display screen assembly 21 . The pre-tightening member 3 is used to apply a force to the display screen assembly 21 so that the display screen assembly 2 and the mounting ring 22 are pressed tightly.

[0061] In this embodiment, the infrared front-end device 100 further includes a pre-tensioning member 3, which is positioned between the eyepiece assembly 1 and the display screen assembly 21. The pre-tensioning member 3 primarily applies a force to the display screen assembly 21 in the opposite direction to the force applied by the mounting ring 22. This design subjects the display screen assembly 21 to two opposing forces, thereby creating a stable, tight connection between the display screen assembly 2 and the mounting ring 22.

[0062] The force applied by the preload member 3 helps maintain the positional stability of the display screen assembly 21, particularly under the impact of firearms. The combined action of the preload member 3 and the mounting ring 22 prevents the display screen assembly 21 from shifting due to external impacts, ensuring parallax accuracy and aiming precision. This design enhances the structural stability of the entire infrared front-end device 100, ensuring optimal performance under a variety of operating conditions.

[0063] Optionally, the pre-tightening member 3 is made of elastic material.

[0064] In this embodiment, the preload member 3 is made of an elastic material, such as a wave spring, providing a simple and effective preload method for the infrared front-end device 100. This design enables the preload member 3 to generate a stable preload force between the eyepiece assembly 1 and the display screen assembly 21, helping to maintain the stable positioning of the display screen assembly 21 and reducing displacement caused by external impact or long-term use.

[0065] In some embodiments, the eyepiece assembly 1 is provided with a mounting platform 11 ; the pre-tightening member 3 is provided between the mounting platform 11 and the display screen assembly 21 .

[0066] In this embodiment, the eyepiece assembly 1 is designed to include a mounting platform 11, which serves as a positioning base for the pre-tensioning member 3. The pre-tensioning member 3 is positioned between the mounting platform 11 and the display screen assembly 21, with its two sides respectively abutting against the mounting platform 11 and the display screen assembly 21. This layout ensures that the pre-tensioning member 3 can effectively transmit the applied force, thereby achieving stable fixation of the display screen assembly 21.

[0067] In some embodiments, the eyepiece assembly 1 is provided with a guide platform 12 ; the pre-tightening member 3 is sleeved on the guide platform 12 .

[0068] In this embodiment, the eyepiece assembly 1 is newly provided with a guide platform 12, which is used to provide a precise mounting position for the pre-tightening member 3. The pre-tightening member 3 is mounted on the guide platform 12, and this design ensures that the pre-tightening member 3 is accurately positioned during installation and movement.

[0069] In some embodiments, the eyepiece assembly 1 is provided with a guide platform 12 , which cooperates with the display screen assembly 21 so that the display screen assembly 21 moves and adjusts under the guidance of the guide platform 12 .

[0070] In this embodiment, the eyepiece assembly 1 is equipped with a guide platform 12. This design is not only used to install and guide the preload member 3, but also ensures coordination with the display screen assembly 21. The presence of the guide platform 12 allows the display screen assembly 21 to move and adjust smoothly thereon, ensuring the accuracy and stability of the display screen assembly 21 during parallax adjustment.

[0071] The coordination of the guide platform 12 and the display screen assembly 21 allows for precise control of the display screen assembly 21's movement. This not only improves the positioning accuracy of the display screen assembly 21 but also enhances the reliability of the entire infrared front-end device 100 during actual use. The design of the guide platform 12 takes into account the stability of the display screen assembly 21 under various operating conditions, including the recoil and vibration generated during firearm firing. Furthermore, the design of the guide platform 12 helps minimize potential swing or deviation of the display screen assembly 21 during adjustment, ensuring precise aiming.

[0072] In some embodiments, the display screen assembly 21 is mounted on the guide platform 12 .

[0073] In this embodiment, the display screen assembly 21 is designed to be sleeved on the guide platform 12. This structural design makes the components from the outside to the inside sequentially the mounting ring 22, the display screen assembly 21, and the guide platform 12. This sleeve arrangement not only makes the entire structure more compact, but also improves the overall structural strength.

[0074] The mounting ring 22, located at the outermost layer, provides a connection point between the display screen assembly 2 and the eyepiece assembly 1. The display screen assembly 21, located within, is precisely positioned and adjusted for movement via the guide platform 12. This exterior-to-interior layered structure ensures that each component remains stable in its intended position, reducing the risk of displacement due to external shock or vibration. Furthermore, the compact housing design helps reduce the weight and size of the entire infrared front-end device 100, enhancing the firearm's portability and operational flexibility.

[0075] In some embodiments, the guide platform 12 is provided with a first structure, and the display screen assembly 21 is provided with a second structure. The first structure cooperates with the second structure to achieve movement adjustment and anti-rotation of the display screen assembly 21 on the guide platform 12.

[0076] In this embodiment, the coordination between the guide platform 12 and the display screen assembly 21 is achieved through carefully designed first and second structures. The guide platform 12 is provided with a first structure, such as guide ribs 121, while the inner periphery of the display screen assembly 21 is provided with a matching second structure, such as a slide groove. This structural design not only allows for precise movement and adjustment of the display screen assembly 21 on the guide platform 12, but also prevents rotation during movement, ensuring stability and accurate positioning of the display screen assembly 21.

[0077] This guiding and anti-rotation design allows the display screen assembly 21 to move smoothly along a predetermined path while maintaining its correct orientation, which is crucial for maintaining the accuracy of the aiming device during shooting. Through the coordination of the first and second structures, the adjustment process of the display screen assembly 21 becomes more controllable and precise, thereby improving the shooter's reliability and efficiency when aiming.

[0078] It should be noted that the mounting ring 22 is moved and adjusted on the eyepiece assembly 1 by rotation, but the rotation of the mounting ring 22 does not cause the display screen assembly 21 to rotate. This is because the display screen assembly 21 is guided and prevented from rotating by the eyepiece assembly 1. The relationship between the mounting ring 22 and the display screen assembly 21 is only a pressure transmission relationship, not a rigid connection.

[0079] In some cases, in order to improve the pressure transmission effect between the mounting ring 22 and the display screen assembly 21, a ring body protruding outward is set on the periphery of the display screen assembly 21. When the mounting ring 22 is mounted on the display screen assembly 21, the sink inside the mounting ring 22 is abutted against the ring body, thereby realizing that when the mounting ring 22 is threadedly rotated relative to the eyepiece assembly 1, the mounting ring 22 pushes the display screen assembly 21 to move and adjust; for the movement adjustment of the display screen assembly 21 in the direction opposite to the pushing direction of the mounting ring 22, the force of the preloaded member 3 pushes the display screen assembly 21 to move in the opposite direction.

[0080] In some embodiments, the display assembly 21 includes:

[0081] Mounting seat 211;

[0082] Display screen 212, mounted on mounting base 211;

[0083] The mounting ring 22 is sleeved on the mounting seat 211 , and the display screen 212 passes through the mounting ring 22 .

[0084] In this embodiment, the display screen assembly 21 consists of a mounting base 211 and a display screen 212. The mounting base 211 serves as a support structure for the display screen 212, providing a stable platform, while the display screen 212 is mounted on the mounting base 211. A mounting ring 22 is mounted on the mounting base 211, and the display screen 212 extends through the mounting ring 22. This design allows the display screen 212 to be adjusted as necessary within the constraints of the mounting ring 22 to achieve alignment with the eyepiece assembly 1.

[0085] In some embodiments, the display screen 212 is fixed on the mounting base 211 by gluing.

[0086] In this embodiment, display screen 212 is secured to mounting base 211 using adhesive. This securement method provides a stable and secure connection, ensuring that display screen 212 does not shift due to vibration or impact during use, thereby ensuring accurate aiming and display screen stability. Adhesive fixation is a simple and effective method that reduces assembly complexity while providing long-term stability.

[0087] In some embodiments, the mounting ring 22 is provided with an operating window 221 communicating with the interior thereof, and the mounting ring 22 is glued and fixed to the eyepiece assembly 1 through the operating window 221 .

[0088] In this embodiment, the access window 221 allows for securement of the mounting ring 22 and the eyepiece assembly 1 after they have been assembled and properly adjusted. This design allows for stable fixation after the final adjustment of the display screen 212, ensuring precise alignment of the display screen 212 on the eyepiece assembly 1.

[0089] This design also means that the movement and adjustment of the display screen 212 relative to the eyepiece assembly 1 are typically completed before the product leaves the factory. Before shipment, the manufacturer will first perform movement adjustments to ensure optimal alignment between the display screen 212 and the eyepiece assembly 1. The operation window 221 is then secured with glue to ensure product stability and durability during use. This process ensures that the infrared front-end device 100 is precisely pre-adjusted and fixed when it is delivered to the end user, allowing users to use it directly without further adjustment.

[0090] In some embodiments, the infrared front-end device 100 further includes a housing 4 , in which an eyepiece assembly 1 and a display screen assembly 2 are disposed.

[0091] In this embodiment, the infrared front-end device 100 further includes a housing 4, which is used to enclose and protect internal components such as the eyepiece assembly 1, the display assembly 2, and the preload member 3. The provision of housing 4 not only enhances the overall structural strength of the device but also helps to protect it from dust and impact, ensuring stable operation of the internal components in various environments.

[0092] During the assembly process, the inner core components, including the eyepiece assembly 1, display assembly 2, and preloaded components 3, are first assembled to ensure that the display 212 can be precisely moved and adjusted and secured to the eyepiece assembly 1. Once the inner core is assembled, it is then integrated with the outer shell 4 to form the complete infrared front-end device 100. Finally, this complete device can be connected to a sight, expanding the sight's infrared imaging capabilities.

[0093] The present application also provides a sighting device, comprising a sighting tool and the above-mentioned infrared front-end device 100 , wherein the infrared front-end device 100 is arranged on the sighting tool.

[0094] The aiming device can be a device for firearms. The aiming device provided in this application combines a traditional sight and an innovative infrared front device 100, so that it not only has the basic functions of a white light sight, but can also be expanded to infrared imaging, thereby enhancing the aiming ability of firearms under various lighting conditions.

[0095] In this combination, the white light aiming function of the sight provides the shooter with accurate aiming in good lighting conditions, while the infrared front device 100 ensures effective observation and aiming at night or in low light environments.

[0096] like Figure 2 and Figure 3 As shown, in the direction of the arrow in the figure, the front and rear ends in opposite directions are indicated. For the infrared front device 100, the eyepiece assembly 1 is located at the rear end of the infrared front device 100, and the display screen assembly 2 is located at the front end of the infrared front device 100. When the infrared front device 100 is provided in a sight, for the sight, the infrared front device 100 is located at the front end of the sight.

[0097] In some cases, the eyepiece assembly 1 is detachably connected to the sight, such as by a threaded connection.

[0098] It should be noted that many of the components mentioned in this application are universal standard parts or components known to those skilled in the art, and their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0099] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0100] The above is a detailed introduction to the infrared front-end device and aiming device provided by this application. This article uses specific examples to illustrate the principles and implementation methods of this application. The description of the above embodiments is only intended to help understand the method and core concept of this application. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of this application, various improvements and modifications can be made to this application, and these improvements and modifications also fall within the scope of protection of the claims of this application.
