[0030] A sight is an optical device that helps users aim at targets accurately. In order to realize the functions of a sight, a sight is usually provided with multiple functional modules, such as a main control component, a display component, and a battery component. However, in existing sights, multiple functional modules are usually distributed along the length of the sight, with a loose layout and occupying a large space, resulting in the sight being too large in size and having poor appearance. At the same time, the sight is heavy, which is not conducive to miniaturization and lightweight design.

[0031] The utility model provides a sighting device which solves the above problems.

[0032] like Figures 1 to 3 As shown, the sight 100 includes a main body 101, an objective lens 80, and an eyepiece 90. The main body 101 includes a housing 10 and a button assembly 20 mounted on the housing 10. It also includes a movement 30, a battery assembly 40, a display assembly 50, and a main control assembly 60 housed within the housing 10. The housing 10 extends along a first direction. The movement 30 and the display assembly 50 are respectively disposed on either side of the battery assembly 40 along the first direction. The button assembly 20 and the main control assembly 60 are respectively disposed on either side of the battery assembly 40 along a second direction, where the second direction is different from the first direction.

The eyepiece 90 is mounted at the other end of the housing 10 along the first direction, and is positioned proximate to the display assembly 50.

[0033] Specifically, the main body 101 of the sight 100 includes a housing 10, a key assembly 20, a movement 30, a battery assembly 40, a display assembly 50 and a main control assembly 60. It can be understood that the key assembly 20, the movement 30, the battery assembly 40, the display assembly 50 and the main control assembly 60 are all functional modules of the sight 100, wherein the key assembly 20 is mounted on the housing 10, and the movement 30, the battery assembly 40, the display assembly 50 and the main control assembly 60 are all housed in the housing 10. In one embodiment, the first direction is as follows Figure 2 The front and rear directions shown are as follows: Figure 1 and Figure 2The housing 10 extends along a first direction, i.e., the longitudinal direction of the housing 10 is the front-to-back direction. The objective lens 80 is mounted at the front end of the housing 10, and the eyepiece 90 is mounted at the rear end of the housing 10.

Furthermore, multiple functional modules do not need to be disposed entirely along the longitudinal direction of the housing 10, thereby effectively avoiding excessive dimensions of the sight 100, improving its aesthetics, and reducing its weight, thereby facilitating a miniaturized and lightweight design.

[0034] In one embodiment, the main control component 60 includes a main board 61 and an FPGA (Field-Programmable Gate Array) 62 electrically connected to the main board 61.

The main board 61 is connected to the inner wall of the outer shell 10 and can conduct heat with the outer shell 10.

[0035] It should be noted that the FPGA board plays a key role in the sight 100, including signal processing, algorithm implementation, data transmission and communication, system control and management, real-time and low latency, flexibility and programmability, and low power management. By leveraging the high performance and flexibility of the FPGA, the sight 100 can implement more complex functions, improve shooting accuracy, and enhance the user experience. The mainboard 61 plays a core role in the sight 100, responsible for data processing, storage management, signal processing, sensor interfacing, data transmission and communication, power management, user interface, system control and management, expansion and upgrades, and other aspects.

The heat generated by the battery 42 during the power supply process can be conducted to the outer shell 10 through the battery compartment 41, thereby dissipating heat through the outer shell 10, improving the heat dissipation effect, and ensuring the normal use of the battery 42. The FPGA62 is arranged close to the battery compartment 41. Specifically, the FPGA62 is arranged close to the bottom of the battery compartment 41, and the FPGA62 can conduct heat with the battery compartment 41. The heat generated by the FPGA62 during operation can be conducted to the battery compartment 41, and the battery compartment 41 and the outer shell 10 can conduct heat, thereby dissipating heat through the outer shell 10, improving the heat dissipation effect, and ensuring the normal use of the FPGA62.

The mounting slot 411 provides space for its installation, resulting in a compact layout and space-saving operation. Furthermore, the mounting slot 411 is located near the FPGA 62, and therefore near the mainboard 61, facilitating control of the mainboard 61.

[0045] In one embodiment, the switch button 70 is electrically connected to the main board 61 through a flexible circuit board. The flexible circuit board can be bent, folded, and curled to adapt to the effective space inside the housing 10, making the overall design more compact and reducing the occupied volume.
