[0018] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0019] like Figures 1 to 7 As shown, a box assembly 100 is provided according to a first aspect of the present disclosure, comprising: a box body 110 having a hot air cavity 1101, a mounting groove 1102 and an air inlet 1103, wherein the mounting groove 1102 and the air inlet 1103 are both connected to the hot air cavity 1101; and an air distributor 120 disposed within the hot air cavity 1101, wherein the air distributor 120 is arranged along the axial direction of the air inlet 1103 corresponding to the air inlet 1103, and the air distributor 120 is clearance-fitted with the cavity wall of the hot air cavity 1101; wherein the mounting groove 1102 is used to place a module to be tested, and the hot air cavity 1101 is used to receive hot air through the air inlet 1103.

[0020] The housing assembly 100 provided in this embodiment includes the aforementioned housing body 110 and the aforementioned air distribution component 120. The housing body 110 forms a hot air cavity 1101, a mounting groove 1102, and an air inlet 1103. Both the mounting groove 1102 and the air inlet 1103 are connected to the hot air cavity 1101. In practical applications, the mounting groove 1102 can be used to place the module under test, thereby ensuring the positional stability of the module under test during the temperature drift test, which is beneficial for ensuring the stable conduct of the temperature drift test. The hot air cavity 1101 can receive hot air through the aforementioned air inlet 1103, thereby providing the temperature field environment required for the test of the module under test. The air distribution component 120 is disposed inside the hot air cavity 1101 and is arranged axially along the air inlet 1103 corresponding to the air inlet 1103. The cavity wall of the hot air cavity 1101 and the air distribution component 120 are clearance-fitted, meaning that the air distribution component 120 and the cavity wall of the hot air cavity 1101 are separated from each other. Based on this, the hot air entering the hot air cavity 1101 through the air inlet 1103 can be blocked by the air distribution component 120 and diffused to the periphery of the air distribution component 120 during the process of flowing towards the mounting groove 1102. Thus, the housing assembly 100 can use the air distribution component 120 to promote the diffusion and flow of hot air in the hot air cavity 1101, improve the hot air flow in the hot air cavity 1101, expand the distribution range of hot air in the hot air cavity 1101, and thus establish a temperature field environment with uniform temperature distribution more quickly during the temperature drift test, which is conducive to improving the temperature drift test efficiency and test effect.

[0021] It should be noted that the housing assembly 100 provided in this embodiment can be used as a component of a camera module temperature drift testing device in practical applications. For example, in practical applications, the aforementioned air inlet 1103 can be connected to the air outlet of the hot air section 200 of the aforementioned camera module temperature drift testing device. The hot air section 200 can output hot air through the aforementioned air outlet, and the temperature of the hot air output by the hot air section 200 is adjustable to establish different temperature field environments within the hot air cavity 1101, thereby adapting to temperature drift tests with different temperature requirements. The aforementioned mounting slot 1102 can hold the module to be tested, which can be a camera module. The housing body 110 can also have a through hole 1104. The through hole 1104 connects the mounting groove 1102 to the external environment. The image acquisition end of the module under test can be arranged corresponding to the through hole 1104 so that the module under test can acquire image information outside the housing component 100 during the temperature drift test. The module under test can be signal connected to the data processing component of the camera module temperature drift test device so that the acquired image information can be transmitted to the data processing component so that the data processing component can process and analyze the image information to achieve the temperature drift performance test of the module under test.

[0022] It is understood that the aforementioned box body 110 and the aforementioned air distribution component 120 can be made of materials with good temperature resistance, such as metal, plastic, or glass. For example, the aforementioned box body 110 can be made of acrylic (polymethyl methacrylate), which ensures the temperature resistance of the box body 110 while providing good light transmittance, thus facilitating observation of the internal condition of the box body 110 by testers during testing and further improving the usability of the box assembly 100. Similarly, the aforementioned air distribution component 120 can also be made of, but is not limited to, acrylic.

[0023] It is understood that the aforementioned hot air cavity 1101 is defined by at least a portion of the inner wall of the aforementioned box body 110. Correspondingly, the cavity wall of the aforementioned hot air cavity 1101 is also defined by the box body 110. The aforementioned mounting groove 1102 can also be formed on the cavity wall of the hot air cavity 1101, thereby improving the connectivity between the hot air cavity 1101 and the mounting groove 1102, and facilitating the application of the temperature field environment of the hot air cavity 1101 to the module under test.

[0024] It is understood that the shape of the aforementioned mounting slot 1102 can be combined with the shape of the module under test so that the mounting slot 1102 can be adapted to the module under test, thereby improving the positional constraint effect of the mounting slot 1102 on the module under test and improving the positional stability of the module under test during the test process.

[0025] It is understood that the aforementioned air distribution component 120 is arranged along the axial direction of the air inlet 1103 corresponding to the air inlet 1103, which means that the air distribution component 120 is located on the axial direction of the air inlet 1103 and is arranged corresponding to the air outlet end of the air inlet 1103. The air outlet end of the aforementioned air inlet 1103 is also one end of the air inlet 1103 connected to the hot air chamber 1101.

[0026] like Figure 3 and Figure 4 As shown, in some examples, the mounting groove 1102 and the air inlet 1103 are arranged opposite each other, and the air distribution component 120 is arranged between the mounting groove 1102 and the air inlet 1103 along the axial direction of the air inlet 1103.

[0027] In this technical solution, the air distribution component 120 can prevent hot air from blowing directly onto the module under test, thus preventing heat from being concentrated on the module under test, reducing the risk of overheating of the module under test during the test, and helping to ensure the test effect of temperature drift test.

[0028] In some examples, in the projection plane perpendicular to the axial direction of the air inlet 1103, the orthographic projection of the air inlet 1103 and the orthographic projection of the mounting groove 1102 are both located within the range of the orthographic projection of the air distribution component 120.

[0029] In this technical solution, the projection relationship between the air inlet 1103, the mounting groove 1102, and the air distribution component 120 is constrained. Based on the aforementioned settings, the airflow shielding effect of the air distribution component 120 between the air inlet 1103 and the mounting groove 1102 can be further improved, thereby more reliably preventing airflow from directly flowing to the mounting groove 1102, reducing the risk of hot air directly blowing onto the module under test, and helping to increase the diffusion range of hot air in the hot air cavity 1101, further improving the temperature distribution uniformity within the hot air cavity 1101.

[0030] It is understood that the orthographic projection of the aforementioned air inlet 1103 and the orthographic projection of the mounting groove 1102 are both within the range of the orthographic projection of the air distribution component 120, which means that the outer contour of the orthographic projection of the air inlet 1103 and the outer contour of the orthographic projection of the mounting groove 1102 do not exceed the outer contour of the orthographic projection of the air distribution component 120.

[0031] In some feasible examples, along the axial direction of the air inlet 1103, the minimum distance between the air distributor 120 and the air inlet 1103 is less than the minimum distance between the air distributor 120 and the mounting groove 1102.

[0032] In this technical solution, the minimum distance between the air distributor 120 and the air inlet 1103 can be set along the axial direction of the air inlet 1103 to be less than the minimum distance between the air distributor 120 and the mounting groove 1102. Based on the aforementioned setting, the air inlet 1103 can be closer to the air distributor 120 than the mounting groove 1102, so that the hot air output from the air inlet 1103 into the hot air chamber 1101 can come into contact with the air distributor 120 more quickly, thereby improving the diffusion efficiency of the hot air in the hot air chamber 1101.

[0033] It is understood that the minimum distance between the aforementioned air distribution component 120 and the air inlet 1103 refers to the minimum distance between the opening of the aforementioned air distribution component 120 and the air inlet 1103; the minimum distance between the aforementioned air distribution component 120 and the mounting groove 1102 refers to the minimum distance between the aforementioned air distribution component 120 and the groove of the mounting groove 1102.

[0034] like Figures 1 to 4 As shown, in some examples, the box body 110 includes: a first end plate 111; a second end plate 112, arranged opposite to the first end plate 111, with a mounting groove 1102 on the side of the second end plate 112 facing the first end plate 111; a plurality of side panels 113, connected between the first end plate 111 and the second end plate 112, the first end plate 111, the second end plate 112 and the plurality of side panels 113 forming a hot air cavity 1101; a mounting base 114, passing through the first end plate 111, with an air inlet 1103; wherein, an air distribution component 120 is disposed on the mounting base 114, and the first end plate 111, the second end plate 112 and the plurality of side panels 113 are all spaced apart from the air distribution component 120.

[0035] In this technical solution, the box body 110 may include the aforementioned first end plate 111, second end plate 112, mounting base 114, and multiple side panels 113. Based on the aforementioned configuration, the box body 110 can use the mounting base 114 to fix the air distribution component 120, and separate the air distribution component 120 from the cavity wall of the hot air chamber 1101, which facilitates the diffusion of hot air through the periphery of the air distribution component 120. At the same time, the mounting base 114 can provide the opening position of the air inlet 1103, which helps to shorten the distance between the air inlet 1103 and the air distribution component 120 and improve the positional correspondence between the air inlet 1103 and the air distribution component 120, thereby enhancing the promoting effect of the air distribution component 120 on the diffusion and flow of hot air.

[0036] It is understood that by opening the mounting groove 1102 and the air inlet 1103 on the aforementioned second end plate 112 and the aforementioned mounting base 114 respectively, the mounting groove 1102 and the air inlet 1103 can be arranged relative to each other, and the air distribution component 120 can be arranged between the mounting groove 1102 and the air inlet 1103 along the axial direction of the air inlet 1103. Thus, the air distribution component 120 can prevent hot air from blowing directly onto the module under test, prevent heat from concentrating on the module under test, reduce the risk of overheating of the module under test during the test, and help ensure the test effect of temperature drift test.

[0037] It is understood that the two ends of the aforementioned mounting base 114 can be located inside and outside the hot air cavity 1101, respectively, and the aforementioned air distribution component 120 is disposed at the end of the mounting base 114 located inside the hot air cavity 1101. The connection between the air distribution component 120 and the mounting base 114 can be direct or indirect, and can be set according to actual needs, without further limitations here.

[0038] For example, such as Figure 1 and Figure 2 As shown, the aforementioned first end plate 111, second end plate 112 and multiple side panels 113 can all be rectangular plates. The first end plate 111 and second end plate 112 are arranged in parallel, and the multiple side panels 113 are vertically connected between the first end plate 111 and the second end plate 112 to form the aforementioned box body 110 and surround the aforementioned hot air cavity 1101. The aforementioned box body 110 and the aforementioned hot air cavity 1101 can both be cuboid in shape.

[0039] For example, such as Figures 2 to 4 As shown, the box body 110 may also include a support column 115, which is connected between the mounting base 114 and the air distribution component 120. Based on this, the air distribution component 120 can form a certain gap distance with the mounting base 114, thereby preventing the air distribution component 120 from covering the air inlet 1103 on the mounting base 114.

[0040] For example, such as Figures 2 to 4 As shown, the housing assembly 100 may further include a duct connector 140, which is detachably mounted on the mounting base 114, and at least a portion of the duct connector 140 is located outside the housing body 110. An air inlet 1103 is used to access hot air through the aforementioned duct connector 140. Based on this, the housing body 110 can be connected to a hot air supply device via the duct connector 140, for example, to the hot air section 200 of a camera module temperature drift testing device, which improves the convenience of pipe connections for the housing assembly 100.

[0041] In some examples, multiple side panels 113 are detachably connected to the second end plate 112.

[0042] In this technical solution, multiple side panels 113 can be detachably connected to the second end plate 112. Based on the aforementioned configuration, the second end plate 112 can be used to open or cover one side of the hot air cavity 1101, thereby facilitating the opening and closing of the hot air cavity 1101, and facilitating the placement and removal of the module to be tested. This improves the ease of cleaning and maintenance within the hot air cavity 1101 and enhances the usability of the housing assembly 100.

[0043] It is understood that the detachable connection between the second end plate 112 and the side enclosure 113 can be, but is not limited to, threaded connection, snap-fit ​​connection, or magnetic connection. There are many ways to detachably connect multiple side enclosures 113 to the second end plate 112, and no further limitations are made here.

[0044] It is understandable that, in practical applications, the housing body 110 may include multiple second end plates 112, which are interchangeably connected to multiple side panels 113, and the structural parameters of the mounting slots 1102 of the multiple second end plates 112 are different. Based on this, in practical applications, the housing assembly 100 can be configured to use mounting slots 1102 that match the second end plates 112 of the module under test, taking into account the structural parameters of the module under test. This facilitates the housing assembly 100's ability to adapt to the fixing requirements of different modules under test during temperature drift testing.

[0045] For example, multiple side panels 113 can be arranged sequentially along the edge of the first end plate 111, and adjacent side panels 113 are connected by screws. At least one side panel 113 is screwed to the first end plate 111, thereby improving the connection reliability between the multiple side panels 113 and the first end plate 111, and thus improving the structural stability of the box body 110.

[0046] like Figures 2 to 4 As shown, in some examples, the box body 110 further includes: a first magnetic element 116 disposed on the side of the side panel 113 away from the first end plate 111; and a second magnetic element 117 disposed on the second end plate 112, the second magnetic element 117 being used to magnetically engage with the first magnetic element 116.

[0047] In this technical solution, the box body 110 may further include the aforementioned first magnetic component 116 and the aforementioned second magnetic component 117. Based on the aforementioned configuration, the side panel 113 and the second end plate 112 can be connected by magnetic attraction, thereby improving the ease of assembly and disassembly of the second end plate 112 and further improving the efficiency of temperature drift testing.

[0048] It is understood that there can be multiple first magnetic components 116 and second magnetic components 117. At least a portion of the side enclosure 113 is provided with first magnetic components 116, and the second magnetic components 117 are arranged in a one-to-one correspondence with the first magnetic components 116. Thus, the second end plate 112 and the side enclosure 113 can form a multi-point magnetic attraction, which is beneficial to improving the installation stability of the second end plate 112.

[0049] like Figure 1 and Figure 4 As shown, in some feasible examples, at least part of the side panel 113 has a balancing hole 1105, which is used to connect the external environment and the hot air chamber 1101. Based on the aforementioned configuration, during the continuous intake of hot air into the hot air chamber 1101, some of the gas medium inside the hot air chamber 1101 can flow out to the external environment through the balancing hole 1105, thereby avoiding the formation of excessive gas pressure inside the hot air chamber 1101. This helps to prevent structural deformation of the box body 110 and ensures the air intake efficiency of the hot air chamber 1101. At the same time, it can prevent the second end plate 112 from loosening due to excessive gas pressure inside the hot air chamber 1101.

[0050] For example, the diameter of the balancing hole 1105 is smaller than the diameter of the air inlet hole 1103; and / or, the cross-sectional area of ​​the balancing hole 1105 is less than or equal to the cross-sectional area of ​​the air inlet hole 1103. It is understood that when there are multiple balancing holes 1105, the sum of the cross-sectional areas of the multiple balancing holes 1105 is less than the cross-sectional area of ​​the air inlet hole 1103. Based on this, excessive exhaust flow from the balancing hole 1105 can be avoided, which helps to ensure a stable thermal environment within the hot air chamber 1101.

[0051] like Figure 5 As shown, in some examples, the housing assembly 100 further includes a limiting member 130 disposed on the second end plate 112, the limiting member 130 being used to limit the relative position between the module to be tested and the second end plate 112.

[0052] In this technical solution, the housing assembly 100 may further include the aforementioned limiting member 130. Based on the aforementioned configuration, when the module to be tested is placed in the mounting slot 1102, the housing assembly 100 can use the limiting member 130 to limit the position of the module to be tested, thereby preventing the module to be tested from falling out of the mounting slot 1102 during the temperature drift test. This helps to further improve the positional stability of the module to be tested within the mounting slot 1102, ensuring the stable conduct of the test process and reducing the probability of damage to the module to be tested.

[0053] like Figure 4 and Figure 5As shown, in some examples, the limiting member 130 includes: a positioning screw 131 disposed on the second end plate 112; an elastic member 132 sleeved on the positioning screw 131, the elastic member 132 being arranged between the head of the positioning screw 131 and the second end plate 112; and a pressure member 133 rotatably sleeved on the positioning screw 131, the pressure member 133 being arranged between the elastic member 132 and the second end plate 112, the pressure member 133 having a first working position and a second working position in the rotation direction; wherein, when the pressure member 133 is in the first working position, it covers at least a portion of the opening of the mounting groove 1102; and when the pressure member 133 is in the second working position, it is offset from the opening of the mounting groove 1102.

[0054] In this technical solution, the limiting member 130 may include the aforementioned positioning screw 131, elastic member 132, and pressure member 133. Based on the aforementioned configuration, the pressure-applying component 133 can be switched between the first and second working positions by rotating relative to the positioning screw 131. During the test, the pressure-applying component 133 can be set to the first working position so that it covers at least part of the groove opening of the mounting slot 1102, thereby reducing the probability of the module under test in the mounting slot 1102 coming out through the groove opening. In this case, the pressure-applying component 133 can abut against the module under test, and the elastic member 132 can apply an elastic force to the pressure-applying component 133 toward the bottom of the mounting slot 1102, thereby pressing the module under test tightly and enhancing the limiting effect of the pressure-applying component 133 on the module under test. When it is necessary to place or remove the module under test, the pressure-applying component 133 can be set to the second working position to avoid the pressure-applying component 133 blocking the groove opening, which is beneficial to ensuring the structural passability of the groove opening.

[0055] Understandably, based on the aforementioned settings, the limiting component 130 has good operational convenience, which helps to ensure the testing efficiency of temperature drift test.

[0056] It is understood that the groove of the mounting groove 1102 is opened on the side of the second end plate 112 facing the first end plate 111 and is connected to the hot air cavity 1101. The bottom of the mounting groove 1102 and the groove of the mounting groove 1102 are arranged opposite to each other along the depth direction of the mounting groove 1102.

[0057] It is understood that the aforementioned pressure-applying member 133 is clearance-fitted with the shank of the positioning screw 131 and is adapted to slide along the axial direction of the positioning screw 131, while the aforementioned elastic member 132 is adapted to elastically deform along the axial direction of the positioning screw 131. Based on this, the pressure-applying member 133 can have good position adjustment flexibility and is adapted to press the module to be tested under the action of the elastic force applied by the elastic member 132.

[0058] It is understood that the aforementioned elastic element 132 may be, but is not limited to, a spring.

[0059] like Figure 6 and Figure 7 As shown, a camera module temperature drift testing device is provided according to a second aspect of the present disclosure, comprising: a housing assembly 100 as described in any of the first aspects above; a hot air section 200, the air outlet of the hot air section 200 being connected to an air inlet 1103.

[0060] The camera module temperature drift testing device provided in this embodiment includes the aforementioned hot air section 200 and the housing assembly 100 as described in any of the first aspects above. The housing assembly 100 includes the aforementioned housing body 110 and the aforementioned air distribution component 120. The housing body 110 forms a hot air cavity 1101, a mounting groove 1102, and an air inlet 1103. Both the mounting groove 1102 and the air inlet 1103 are connected to the hot air cavity 1101. In practical applications, the aforementioned mounting groove 1102 can be used to place the module under test, thereby ensuring the positional stability of the module under test during the temperature drift test, which is beneficial for ensuring the stable conduct of the temperature drift test. The aforementioned hot air section... The air outlet of 200 is used to output hot air and is connected to the air inlet 1103 of the housing assembly 100. The aforementioned hot air cavity 1101 can be connected to hot air through the aforementioned air inlet 1103, thereby providing the temperature field environment required for testing the module under test. The air distribution component 120 is disposed inside the hot air cavity 1101 and is arranged along the axial direction of the air inlet 1103 corresponding to the air inlet 1103. The cavity wall of the hot air cavity 1101 is clearance-fitted with the air distribution component 120, that is, the air distribution component 120 is separated from the cavity wall of the hot air cavity 1101. Based on this, the hot air entering the hot air cavity 1101 through the air inlet 1103 can be blocked by the air distribution component 120 and diffused to the periphery of the air distribution component 120 during the process of flowing towards the mounting groove 1102. Thus, the housing assembly 100 can use the air distribution component 120 to promote the diffusion and flow of hot air in the hot air cavity 1101, improve the hot air flow in the hot air cavity 1101, expand the distribution range of hot air in the hot air cavity 1101, and thus establish a temperature field environment with uniform temperature distribution more quickly during the temperature drift test, which is conducive to improving the temperature drift test efficiency and test effect.

[0061] It should be noted that the camera module temperature drift testing device provided in this embodiment can be used to perform temperature drift testing on camera modules in practical applications, and the aforementioned module to be tested can be a camera module. For example, in practical applications, the temperature of the hot air output by the aforementioned hot air section 200 is adjustable so as to establish different temperature field environments within the hot air cavity 1101, thereby adapting to temperature drift tests with different temperature requirements; the aforementioned mounting slot 1102 can hold the module to be tested; the box body 110 can also have a through hole 1104, which connects the mounting slot 1102 to the external environment, and the image acquisition end of the aforementioned module to be tested can be arranged corresponding to the aforementioned through hole 1104 so as to acquire image information from outside the box assembly 100 during the temperature drift test; the camera module temperature drift test device can also include a data processing component, and the module to be tested can be signal-connected to the data processing component of the camera module temperature drift test device so as to transmit the acquired image information to the data processing component so as to process and analyze the aforementioned image information, thereby realizing the temperature drift performance test of the module to be tested.

[0062] It is understood that the aforementioned box body 110 and the aforementioned air distribution component 120 can be made of materials with good temperature resistance, such as metal, plastic, or glass. For example, the aforementioned box body 110 can be made of acrylic, thereby ensuring the temperature resistance of the box body 110 while providing good light transmittance, facilitating observation of the internal condition of the box body 110 during testing, and further improving the usability of the box assembly 100. Similarly, the aforementioned air distribution component 120 can also be made of, but is not limited to, acrylic.

[0063] It is understood that the aforementioned hot air cavity 1101 is defined by at least a portion of the inner wall of the aforementioned box body 110. Correspondingly, the cavity wall of the aforementioned hot air cavity 1101 is also defined by the box body 110. The aforementioned mounting groove 1102 can also be formed on the cavity wall of the hot air cavity 1101, thereby improving the connectivity between the hot air cavity 1101 and the mounting groove 1102, and facilitating the application of the temperature field environment of the hot air cavity 1101 to the module under test.

[0064] It is understood that the shape of the aforementioned mounting slot 1102 can be combined with the shape of the module under test so that the mounting slot 1102 can be adapted to the module under test, thereby improving the positional constraint effect of the mounting slot 1102 on the module under test and improving the positional stability of the module under test during the test process.

[0065] It is understood that the aforementioned air distribution component 120 is arranged along the axial direction of the air inlet 1103 corresponding to the air inlet 1103, which means that the air distribution component 120 is located on the axial direction of the air inlet 1103 and is arranged corresponding to the air outlet end of the air inlet 1103. The air outlet end of the aforementioned air inlet 1103 is also one end of the air inlet 1103 connected to the hot air chamber 1101.

[0066] like Figure 6 and Figure 7 As shown, in some examples, the hot air unit 200 includes a hot air gun 210, the air outlet of which is connected to the air inlet 1103.

[0067] In this technical solution, the hot air unit 200 may include the aforementioned hot air gun 210. Based on the aforementioned configuration, the hot air used to adjust the internal temperature of the hot air cavity 1101 can be provided by the hot air gun 210, thereby improving the portability of the hot air unit 200 and facilitating testing operations by handheld hot air gun 210 at room temperature. This enhances the convenience of the testing process and improves the miniaturization level of the camera module temperature drift testing device.

[0068] It is understandable that the hot air output temperature of the aforementioned hot air gun 210 is adjustable so as to establish different temperature field environments in the hot air chamber 1101, thereby adapting to temperature drift tests with different temperature requirements.

[0069] In some feasible examples, the volume of the housing component 100 is smaller than that of the hot air gun 210, which can further improve the miniaturization and portability of the camera module temperature drift test device, and help improve the ease of use of the camera module temperature drift test device.

[0070] In some feasible examples, the hot air unit 200 may also include an air supply duct 220, which connects the air outlet of the hot air gun 210 and the air inlet 1103. It is understood that when the housing assembly 100 includes the aforementioned duct connector 140, the air supply duct 220 may be connected between the air outlet of the hot air gun 210 and the aforementioned duct connector 140.

[0071] Furthermore, since the camera module temperature drift testing device provided in this embodiment includes the housing component 100 as described in any of the first aspects above, it possesses all the beneficial effects of the housing component 100, which will not be elaborated here.
