[0039] As mentioned above, in order to solve the shortcomings of the prior art of using screws or bolts to connect and fix the shell, the present application provides a screwless fixing method for an electronic device shell and a thermal imager using such an electronic device shell, which utilizes the internal structural parts of the product and adopts a threaded connection method to limit the freedom of the shell to be fixed in all directions, thereby achieving fixation of the shell.

[0040] See also Figure 1 and Figure 2 The electronic device housing of one embodiment of the present application includes a first shell 10, a second shell 20 and a battery compartment 50. The first shell 10 is connected to one end of the second shell 20 to form an internal accommodating space; the pressure ring 30 presses the first shell 10 and is threadedly engaged with the shell connector 40 fixed in the second shell 20 to install and fix the first shell 10 and the second shell 20; the battery compartment 50 passes through the first shell 10 and is threadedly engaged with the shell connector 40 to further fix and tighten the first shell 10 and the second shell 20.

[0041] For details, please refer to Figure 3 and Figure 4, the first shell 10 is the end shell of the electronic device shell, the second shell 20 is the middle shell of the electronic device, and the first shell 10 is buckled on one end of the second shell 20. In order to connect the first shell 10 and the second shell 20 without screws or bolts, the first shell 10 is provided with a hole step 11, and the shell connector 40 fixed inside the second shell 20 is correspondingly provided with a first threaded connection part 41, and the first threaded connection part 41 can be threadedly connected with the pressure ring 30. The first shell 10 is also provided with a battery compartment installation hole 12, so that the battery compartment 50 can pass through and be installed in the second shell 20. In the illustrated embodiment, the battery compartment installation hole 12 is obliquely arranged above the hole step 11, that is, the axial direction of the hole step 11 intersects with the axial direction of the battery compartment 50, that is, the axial direction of the first threaded connection part 41 intersects with the axial direction of the second threaded connection part 42.

[0042] When the first shell 10 and the second shell 20 are assembled, a part of the shell connector 40 will extend into the opening step 11 of the first shell 10, and the first threaded connection part 41 is arranged on the part of the shell connector 40 extending into the opening step 11; the pressing ring 30 is provided with a corresponding internal threaded part 31, and the internal threaded part 31 of the pressing ring 30 and the external thread of the first threaded connection part 41 of the shell connector 40 can be threadedly connected, and the end face of the pressing ring 30 is matched with the opening step 11 of the first shell 10. When the pressing ring 30 is screwed with the first threaded connection part 41 through the thread, the pressing ring 30 will press the first shell 10 toward the second shell 20 through the opening step 11, thereby pressing the first shell 10 and the second shell 20 tightly.

[0043] Please refer to Figure 5 and Figure 6 In the illustrated embodiment, the opening step 11 is formed by being recessed from the opening of the first shell 10 to the second shell 20, and the size of the middle hole of the opening step 11 allows the first threaded connection portion 41 of the shell connector 40 to extend therefrom, and the size of the step surface of the opening step 11 allows the pressure ring 30 to be placed therein.

[0044] The front opening shape of the second shell 20 matches the flange shape of the rear end of the first shell 10 , so that the first shell 10 can be snapped onto the second shell 20 from the front end, and the flange at the rear end of the first shell 10 penetrates into the front opening of the second shell 20 .

[0045] The pressure ring 30 is an annular pressure piece, and the outer diameter of the pressure ring 30 is smaller than the size of the step surface of the opening step 11, so that the pressure ring 30 can be placed in the opening step 11 on the first shell 10, and one end surface of the pressure ring 30 contacts the step surface of the opening step 11. The internal thread portion 31 is arranged on the inner side of the pressure ring 30, and is used for threaded connection with the first threaded connection portion 41 of the shell connector 40. A plurality of slots 32 are arranged on the other end surface of the pressure ring 30 away from the step surface of the opening step 11, and the length direction of the slots 32 is opened along the radial direction of the pressure ring 30, so as to facilitate the pressure ring 30 to be screwed by a tool such as a slotted screwdriver.

[0046] The shell connector 40 is a part fixed inside the second shell 20, and is used to assemble parts such as hardware boards inside the electronic device. The shell connector 40 can be fixed to the second shell 20 by, for example, locking 4 screws, so as to form a whole with the second shell 20. The shell connector 40 is provided with a first threaded connection part 41 and a second threaded connection part 42, and the first threaded part 41 and the second threaded connection part 42 are respectively used to be threadedly connected with the pressure ring 30 and the battery compartment 50. The first threaded part 41 passes through the opening step 11 on the first shell 10 from the shell connector 40 to the front end, and an external thread is provided on the part placed on the opening step 11 at the front end. The external thread of the first threaded part 41 cooperates with the internal thread part 31 of the pressure ring 30. The second threaded connection part 42 is arranged at the installation position of the battery compartment 50 in the second shell 20, and the second threaded connection part 42 is annular with an internal thread, which is used to cooperate with the compartment body thread 51 on the battery compartment 50.

[0047] The battery compartment 50 is used to hold the battery and is installed in the cavity formed by the first housing 10 and the second housing 20 to provide power for the electronic components inside the electronic device. More specifically, the battery compartment 50 is cylindrical and includes a compartment cover 52 and a compartment barrel 53. The compartment cover 52 is screwed on one end of the compartment barrel 53, so that the battery can be put in, taken out or replaced by screwing the compartment cover 25.

[0048] Since the area of ​​the pressing ring 30 is small, the part of the first shell 10 away from the pressing ring 30 may not be pressed tightly. Based on this, a threaded fit is added between the existing battery compartment 50 and the shell connector 40. Figure 7 and Figure 8A body thread 51 is provided on the outer wall of the battery compartment 50. The body thread 51 is arranged on the compartment tube 53 and corresponds to the second threaded connection part 42. The external thread of the body thread 51 is threadedly matched with the internal thread of the second threaded connection part 42. The end face of the compartment cover 55 of the battery compartment 50 forms a stop face 54, which can be matched with the end face of the battery compartment mounting hole 12. When the battery compartment 50 rotates forward toward the internal thread of the second shell 20, the stop face 54 of the battery compartment 50 forms a tight fit with the end face of the battery compartment mounting hole 12, which can limit the freedom of the first shell 10 relative to the second shell 20 in the vertical direction. In this way, the entire first shell 10 can be pressed onto the second shell 20 by the pressure ring 30 and the battery compartment 50, the overall pressing force is relatively uniform, and the overall protection level of the product is also improved, for example, it can reach the IP67 level.

[0049] The electronic device housing structure of the present application fixes the first shell 10 and the second shell 20 in a screwless manner, and uses the shell connector 40 fixed inside the second shell 20 for assembling internal parts to set the first threaded connection part 41, and correspondingly sets the pressure ring 30 and the first threaded connection part 41, and the pressure ring 30 is placed on the opening step 11 on the first shell 10. Through the threaded fit between the pressure ring 30 and the first threaded connection part 41, the first shell 10 is pressed toward the second shell 20 to form a fixed connection; using the battery compartment 50 already provided in the electronic device housing to set the compartment body thread 51, the second threaded connection part 42 is correspondingly set on the shell connector 40, so that through the threaded fit between the compartment body thread 51 and the second threaded connection part 42, the stop surface 54 of the battery compartment 50 forms a tight fit with the end face of the battery compartment mounting hole 12, further limiting the freedom of the first shell 10 relative to the second shell 20.

[0050] See also Fig. 9 and Fig.10 , which is a structural schematic diagram of a thermal imager using the above-mentioned electronic device housing, wherein the first housing 10 is the front housing of the thermal imager, the second housing 20 is the middle housing of the thermal imager, the pressure ring 30 is arranged at the opening step 11 of the first housing 10, the housing connector 40 is fixed inside the second housing 20, the battery compartment 50 extends obliquely into the housing and the end surface of the compartment cover 52 forms a stop surface 54.

[0051] Please continue to refer to Fig.11 and Fig.12 The thermal imager further includes a third housing 60, an eyepiece assembly 70, an objective lens assembly 80 and a display screen assembly 90. The eyepiece assembly 70 is mounted at the front end of the first housing 10, the objective lens assembly 80 is mounted at the rear end of the third housing 60, and the objective lens assembly 80, the infrared detector, the display screen assembly 90 and the eyepiece assembly 70 are sequentially arranged along the infrared optical axis direction.

[0052] The housing of the thermal imager, including the first housing 10, the second housing 20 and the third housing 60, is formed by die-casting of magnesium alloy, which can reduce the weight of the whole device while ensuring the strength.

[0053] A magnetic suction head 21 is provided on one side of the second housing 20 , and the magnetic suction head 21 can be used to charge the thermal imager and perform data transmission functions.

[0054] In the illustrated embodiment, the third housing 60 is fixed to the end of the second housing 20 opposite to the first housing 10 by screws. It is understood that the third housing 60 can also be connected to the second housing 20 in a screwless manner similar to the first housing 10.

[0055] The thermal imager can be applied as a dual-purpose thermal imager for gun sighting and hand-held use, and its working process is as follows: the infrared light reflected by the object is transmitted from the objective lens assembly 80 to the infrared detector in the third housing 60, and image data is formed after the infrared light is processed. Then, a series of electric control boards in the housing connector 40 process the relevant signals and give the device an adjustment function, and output the data to the display assembly 90. The human eye can observe the image displayed on the display assembly 90 through the eyepiece assembly 70.

[0056] In summary, the electronic device housing and thermal imager of the present application provide a screwless fixing method, which utilizes the internal structural parts of the electronic device and adopts a threaded connection method to limit the freedom of the housing to be fixed in all directions, thereby achieving the fixing of the housing. The outer surface of the electronic device housing does not need to provide a locking end surface and assembly space for the screws, and there is no need to design a screw column inside, which reduces the restrictions on the internal structure and the requirements for space.
