[0035] The features and exemplary embodiments of various aspects of the present application will be described in detail below. For the purpose of making the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than limiting the present application. For those skilled in the art, the present application can be implemented without some of these specific details. The following description of the embodiments is only intended to provide a better understanding of the present application by showing examples of the present application.

[0036] It should be noted that in this article, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising..." does not exclude the presence of additional identical elements in the process, method, article or device comprising the said element.

[0037] As a provider of electrical component connections, the PCB (Printed Circuit Board) is made by electronic printing technology and mainly consists of an insulating substrate, conductor lines, etc. The PCB is widely used in various electronic devices, such as computers, mobile phones, TVs, home appliances, etc. At the same time, the PCB is also a key component in the fields of industrial control, automotive electronics, aerospace, etc.

[0038] In the production process of the PCB, in order to evaluate its reliability and performance in actual use, temperature and humidity experiments are usually carried out on the PCB. Before the detection, the PCB needs to be fixed. In the related technology, connection holes are usually drilled in advance on the mounting plate according to the hole positions on the PCB, and then the PCB is connected and fixed to the mounting plate. After the installation of the PCB is completed, the PCB is experimentally detected. Since the PCB has different specifications and models, and the connection hole positions on the PCBs of different specifications and models are different, and there is no fixed spacing between the connection holes, it is necessary to drill holes separately on the mounting plate, resulting in low installation and positioning efficiency of the PCB, and ultimately low experimental test efficiency of the PCB.

[0039] In view of this, please refer to Figures 1 to 4 , an embodiment of the present application provides a fixing structure for fixing a to-be-fixed part. The fixing structure includes a mounting member 10 and a plurality of support components 20. A plurality of tracks 11 are arranged at intervals on the mounting member 10, and the plurality of support components 20 are respectively arranged on the plurality of tracks 11. The support component 20 includes a sliding member 21 and a support member 22. The sliding member 21 is slidably connected to the track 11, and a connecting portion 221 for connecting the to-be-fixed part is provided on the support member 22. The sliding member 21 is movably connected to the support member 22 to change the relative position between the connecting portion 221 and the sliding member 21.

[0040] The fixing structure provided by the embodiments of the present application is used to fix the position of the to-be-fixed component. In the actual production process, it is necessary to fix the positions of certain structures for subsequent operations. Exemplarily, during the production and testing process of a PCB board, in some production experiments, it is necessary to fix the PCB board on a specific structure and perform subsequent operations after fixing the position of the PCB board. In the present application, the to-be-fixed component can be a PCB board, and the fixing structure is used to fix the position of the PCB board. Of course, the fixing structure provided by the embodiments of the present application is not limited to fixing the PCB board, and can also fix structures such as plastic boards and wooden boards.

[0041] Specifically, the fixing structure includes a mounting member 10 with a fixed position and a plurality of support components 20 connected to the mounting member 10. The mounting member 10 serves as the main body of the fixing structure to provide a position installation reference. On the one hand, the support components 20 are connected to the mounting member 10, and on the other hand, they are connected to the to-be-fixed component. The to-be-fixed component is installed and connected to the mounting member 10 through the support components 20. When the position of the mounting member 10 is fixed, the positions of the support components 20 and the to-be-fixed component are also fixed, thereby realizing the positioning and installation of the to-be-fixed component.

[0042] A plurality of tracks 11 are arranged at intervals on the mounting member 10, and a plurality of support components 20 are respectively arranged on the plurality of tracks 11. It can be understood that the support and connection of the to-be-fixed component are not achieved by a single support component 20, but by a plurality of support members 22 jointly connecting to the to-be-fixed component to realize the support of the to-be-fixed component. A plurality of support components 20 are arranged on each of the plurality of tracks 11 to facilitate the formation of a stable support for the to-be-fixed component by the plurality of support components 20.

[0043] The support component 20 includes a sliding member 21 and a support member 22 connected to the sliding member 21. The sliding member 21 is slidably connected to the track 11, and a connecting portion 221 for connecting the to-be-fixed component is provided on the support member 22. During the connection and fixing of the to-be-fixed component, the connection position on the to-be-fixed component is corresponded to the connecting portion 221. By slidably connecting the sliding member 21 to the track 11, the sliding member 21 can drive the support member 22 to change the position of the connecting portion 221 along the arrangement of the track 11, thereby corresponding to different connection positions on the to-be-fixed component.

[0044] Furthermore, the sliding member 21 and the support member 22 are movably connected to change the relative position between the connecting portion 221 and the sliding member 21. It can be understood that after the sliding member 21 slides to a preset position along the track 11, through the movable connection of the support member 22 relative to the sliding member 21, the connecting portion 221 can further change its position within a certain movable space to further adapt to the connection position on the to-be-fixed component.

[0045] For the setting of the track 11 on the mounting member 10, the track 11 can be set as a straight track 11 or a curved track 11. At the same time, for the setting of the support assembly 20 in the track 11, a preset number of support assemblies 20 can be installed inside the track 11, and the position of the support assembly 20 can be directly adjusted when in use.

[0046] For the setting of the connecting portion 221, it corresponds to the structure at the connecting position on the member to be fixed. In some embodiments, a first hole is formed at the connecting position on the member to be fixed, and the connecting portion 221 can be set as a connecting pin. The connecting pin can be inserted into the first hole, or a second hole is provided in the connecting portion 221, and the member to be fixed is connected to the support member 22 by means of a connecting screw.

[0047] In summary, in the fixing structure provided by the embodiments of the present application, the member to be fixed is connected to the mounting member 10 through the support assembly 20 to fix the position of the member to be fixed. Further, the interval between the plurality of support assemblies 20 can be conveniently adjusted to correspond to the connecting positions on different members to be fixed. First, the support assembly 20 includes a sliding member 21 capable of sliding along the track 11 and a support member 22 connected to the sliding member 21. When the sliding member 21 slides along the track 11, the position of the support member 22 can be changed. When a plurality of support assemblies 20 all slide along the track 11, the distance between different support members 22 can be adjusted to adapt to the distance between different connecting positions on different members to be fixed. Further, the support member 22 is movably connected to the sliding member 21, and a connecting portion 221 is provided on the support member 22. The member to be fixed is connected through the connecting portion 221. After the position of the sliding member 21 is fixed, based on the movable connection between the support member 22 and the sliding member 21, the support member 22 can undergo a relative displacement change relative to the sliding member 21 within a certain space, which also makes the position of the connecting portion 221 readjusted, so that the distance between the connecting portions 221 in each support assembly 20 can be adjusted to a greater extent to further adapt to the connecting positions on different specifications and models of members to be fixed, and further facilitate the connection and fixing of the member to be fixed.

[0048] In some embodiments, the support member 22 includes a first support body 222 connected to the sliding member 21 and a second support body 223 rotatably connected to the first support body 222, and the connecting portion 221 is provided on the second support body 223. The sliding member 21 and the second support body 223 are respectively located on both sides of the first support body 222 along the first direction X, and the first direction X intersects with the extending direction of the track 11.

[0049] The support member 22 includes a first support body 222 and a second support body 223. The first support body 222 and the second support body 223 are separately arranged. The first support body 222 is used to connect with the sliding member 21. The second support body 223 is rotatably arranged relative to the first support body 222, and the second support body 223 is used to connect the part to be fixed. By setting the support member 22 in the form of two separate parts, the functions and structures between the two structural members can be clear, which is convenient for the connection between the part to be fixed, the support member 22 and the sliding member 21. At the same time, the connecting portion 221 is arranged on the second support body 223. By rotating between the second support body 223 and the first support body 222, the distance between the connecting portion 221 and the first support body 222 is adjusted. During the rotation of the second support body 223, the adjustment track of the connecting portion 221 is fixed, and no additional structure is required to adjust the position of the connecting portion 221, so that the structure of the support member 22 is simple.

[0050] Furthermore, the projection of the connecting portion 221 on the mounting member 10 is located between adjacent rails 11 , so that the adjustable spacing of the connecting portion 221 can be extended to the outside of the rails 11 . In combination with the multiple supporting components 20 inside the multiple rails 11 , the connecting portion 221 is provided, thereby expanding the adjustable spacing of the connecting portion 221 and increasing the connection area of ​​the connecting portion 221 .

[0051] In addition, the sliding member 21 and the second support body 223 are respectively located on both sides of the first support body 222 along the first direction X, and the first direction X intersects with the extension direction of the track 11. When the sliding member 21 is connected to the track 11, the first support body 222 is connected to the sliding member 21, and the second support body 223 is then connected to the side of the first support body 222 away from the sliding member 21, and then the part to be fixed is connected to the second support body 223. By setting the above structural position relationship, a gap can be formed between the second support body 223 and the mounting member 10, providing an operating space for the connection between the part to be fixed and the second support body 223, and facilitating the connection and fixation of the part to be fixed.

[0052] In some embodiments, the second support body 223 includes a first body portion 2231 and a first connecting portion 2232 connected to the first body portion 2231, and a first convex portion 2233 protruding from a side wall of the first connecting portion 2232 is disposed at one end of the first connecting portion 2232 away from the first body portion 2231. The first support body 222 is provided with a first through hole 2221 along the first direction X, and a second convex portion 2222 protruding from a hole wall of the first through hole 2221 is disposed at one end of the first through hole 2221 close to the first body portion 2231, and the first convex portion 2233 and the first body portion 2231 are located on both sides of the second convex portion 2222 along the first direction X, and the first convex portion 2233 and the second convex portion 2222 are disposed in contact with each other in the first direction X.

[0053] Considering that a plurality of support assemblies 20 are arranged on the mounting member 10, and the intervals between the plurality of support assemblies 20 are different and often need to be adjusted, in order to avoid interference between the various structures, the rotation connection between the second support body 223 and the first support body 222 is realized inside the structure thereof. Specifically, the second support body 223 includes a first body portion 2231 and a first connecting portion 2232 connected to the first body portion 2231, and a first convex portion 2233 protruding from the side wall of the first connecting portion 2232 is arranged at one end of the first connecting portion 2232 away from the first body portion 2231. The connecting portion 221 is arranged on the first body portion 2231, and is connected to the inside of the first support body 222 through the first connecting portion 2232 and the first convex portion 2233, so that only the first body portion 2231 of the second support body 223 is exposed to the outside.

[0054] A first through hole 2221 is opened inside the first support body 222 along the first direction X, and a second convex portion 2222 protruding from the hole wall of the first through hole 2221 is provided at one end of the first through hole 2221 close to the first main body portion 2231. The first convex portion 2233 is located inside the first through hole 2221, and the first convex portion 2233 is located on the side of the second convex portion 2222 away from the first body. The first convex portion 2233 and the second convex portion 2222 are arranged in contact with each other in the first direction X to limit the displacement of the first main body portion 2231 and the first support body 222 in the first direction X. The first protrusion 2233 is located inside the first through hole 2221 and can rotate relative to the first through hole 2221. The first connecting portion 2232 is inserted into the second protrusion 2222 and can rotate relative to the second protrusion 2222, so as to achieve the effect of the second main body portion 211 rotating relative to the first support body 222. The first connecting portion 2232, the first protrusion 2233 and the second protrusion 2222 are all arranged inside the first support body 222, which simplifies the overall structure after the first support body 222 is connected to the second support body 223, and avoids the structural interference problem between multiple support components 20.

[0055] In some embodiments, the track 11 passes through the mounting member 10 along the first direction X. The sliding member 21 includes a second body portion 211 and a second connecting portion 212 connected between the second body portion 211 and the support member 22, the second connecting portion 212 passes through the track 11, and the support member 22 and the second body portion 211 are respectively arranged on both sides of the mounting member 10 along the first direction X.

[0056] In order to facilitate the connection between the sliding member 21, the supporting member 22 and the track 11, the track 11 is arranged to pass through the mounting member 10 along the first direction X, so that both sides of the track 11 along the first direction X are open structures to facilitate the connection between the sliding member 21 and the supporting member 22.

[0057] To improve the convenience and stability of the connection between the sliding member 21 and the track 11, the sliding member 21 includes a second body portion 211 and a second connecting portion 212. The second connecting portion 212 is disposed through the track 11 along the first direction X. The support member 22 and the second body portion 211 are respectively on both sides of the mounting member 10 along the first direction X. Both ends of the second connecting portion 212 are respectively connected to the second body portion 211 and the support member 22. In some embodiments, the second body portion 211 and the second connecting portion 212 may be provided as an integral structure, and one end of the second connecting portion 212 can be connected to the support member 22 by passing through the track 11. At the same time, the second connecting portion 212 is inside the track 11, which can ensure the reliability of the sliding between the sliding member 21 and the track 11.

[0058] In some embodiments, the projection of the second body portion 211 along the first direction X is at least partially between adjacent tracks 11; and / or, the projection of the support member 22 along the first direction X is at least partially between adjacent tracks 11.

[0059] To prevent the sliding member 21 and the support member 22 from detaching from the track 11 in the first direction X, at least a part of the projection of the second body portion 211 along the first direction X is located between adjacent tracks 11. That is to say, when the second body portion 211 and the mounting member 10 are displaced in the first direction X, the second body portion 211 can come into contact with the mounting member 10 to limit the movement between the two. Similarly, at least a part of the projection of the support member 22 along the first direction X is between adjacent tracks 11. Since the support member 22 and the second body portion 211 are on both sides of the mounting member 10 along the first direction X, the above arrangement can make the mounting member 10 between the second body portion 211 and the support member 22, avoiding the detachment of the support member 22 and the sliding member 21 from the mounting member 10 in the first direction X.

[0060] In some embodiments, the second body portion 211 and the support member 22 are slidably connected in the first direction X. The slidable connection between the second body portion 211 and the support member 22 in the first direction X can adjust the distance between the second body portion 211 and the support member 22 in the first direction X. On the one hand, it can adjust the height of the connecting portion 221 to adapt to the connection of the to-be-fixed members with different heights. On the other hand, it can make the second body portion 211 and the support member 22 clamp the mounting member 10 to fix the sliding of the support member 22 and the sliding member 21 relative to the mounting member 10.

[0061] In some embodiments, the support member 22 includes a first support body 222 connected to the sliding member 21. A first through hole 2221 is formed in the first support body 222 along the first direction X. The first support body 222 is further provided with a third convex portion 2223 protruding from the side wall of the first through hole 2221. One end of the second connecting portion 212 away from the second body portion 211 is provided with a fourth convex portion 213 protruding from the side wall of the second connecting portion 212. The fourth convex portion 213 and the second body portion 211 are on both sides of the third convex portion 2223 along the first direction X, and the projections of the third convex portion 2223 and the fourth convex portion 213 in the first direction X at least partially overlap.

[0062] Considering that a plurality of support components 20 are provided on the mounting member 10, the intervals between the plurality of support components 20 are different and often need to be adjusted. In order to avoid interference between various structures, the sliding connection between the second body portion 211 of the sliding member 21 and the support member 22 is realized inside its own structure. Specifically, a first through hole 2221 is provided in the first support body 222 along the first direction X, and a third convex portion 2223 protruding from the side wall of the first through hole 2221 is provided inside the first through hole 2221. A fourth convex portion 213 protruding from its side wall is provided on the second connecting portion 212. The fourth convex portion is inside the first through hole 2221, and the fourth convex portion 213 and the second body portion 211 are on both sides of the third convex portion 2223 along the first direction X. That is, the fourth convex portion 213 can slide inside the first through hole 2221 along the first direction X. The projections of the third convex portion 2223 and the fourth convex portion 213 in the first direction X at least partially overlap to limit the sliding of the fourth convex portion 213 inside the first through hole 2221 and prevent the fourth convex portion 213 from sliding out of the first through hole 2221.

[0063] In some embodiments, the support member 22 further includes a second support body 223 rotatably connected to the first support body 222. The second support body 223 is provided with a second through hole 2234 penetrating along the first direction X. One end of the second connecting portion 212 facing away from the second body portion 211 is recessed inward along the first direction X to form a connection hole 2121. The fixing structure further includes a connecting member. A part of the connecting member is inside the first through hole 2221, and the other part is connected to the connection hole 2121.

[0064] When the second support body 223 is rotatably connected to the first support body 222 around the first direction X and the sliding member 21 is slidably connected to the first support body 222 along the first direction X, in order to facilitate the simultaneous locking and positioning of the rotational connection and the sliding connection, a second through hole 2234 is formed in the second support body 223, and a connection hole 2121 is formed in the second connecting portion 212. The connecting member is simultaneously connected to the second through hole 2234 and the connection hole 2121, so that the sliding member 21 and the second support body 223 simultaneously clamp the first support body 222, and the relative position is restricted by the frictional force generated during the clamping contact.

[0065] Specifically, the connecting hole 2121 can be set as a threaded hole, and the connecting member is provided with a locking bolt. One end of the locking bolt passes through the second through hole 2234 and is connected to the connecting hole 2121. During the process of the threaded connection between the locking bolt and the connecting hole 2121, the second support body 223 and the sliding member 21 approach each other, clamping the first support body 222. The frictional force generated by the clamping restricts the relative rotation between the second support body 223 and the first support body 222 and the relative sliding between the sliding member 21 and the first support body 222. To facilitate the tightening of the locking bolt, the outer part of the first support body 222 is set as a square structure to limit the rotation of the first support body 222 and facilitate the connection between the locking bolt and the connecting hole 2121.

[0066] In some embodiments, a first through hole 2221 is provided in the support member 22 along the first direction X, and at least a first inlet / outlet 224 and a second inlet / outlet 225 communicating with the first through hole 2221 are provided on the side wall of the support member 22.

[0067] After some to-be-fixed parts are connected and fixed, it may be necessary to connect multiple to-be-fixed parts through a linear structure. For example, after the PCB boards are fixed, it is necessary to connect multiple PCB boards through wires. To facilitate the arrangement and accommodation of the linear structure, a first through hole 2221 is provided on the support member 22, and a first inlet / outlet 224 and a second inlet / outlet 225 connected to the first through hole 2221 are provided on the side wall of the support member 22. Taking the fixation of the PCB board as an example, after the connection and fixation, wires with a diameter smaller than the first inlet / outlet 224 and the second inlet / outlet 225 can pass through the support member 22 through the first inlet / outlet 224 and the second inlet / outlet 225, so as to limit and arrange the wires by the structure on the support member 22 and prevent the wires from falling off. For wires with a diameter larger than the first inlet / outlet 224 and the second inlet / outlet 225, they can be fixed by using a cable tie with a diameter smaller than the first inlet / outlet 224 and the second inlet / outlet 225. Specifically, the cable tie is first passed through the first inlet / outlet 224 and the second inlet / outlet 225, and then the wire is tied to the support member 22 to achieve the limitation and arrangement of the wire.

[0068] In some embodiments, a plurality of connecting portions 221 are provided on each support member 22, and the plurality of connecting portions 221 are spaced apart along the circumferential trajectory of the first direction X on the support member 22. The track 11 provided on the mounting member 10 and the support assembly 20 provided on the track 11 form a relatively large connecting area, and a plurality of components to be fixed can be connected inside the connecting area. In order to make full use of each support assembly 20, a plurality of connecting portions 221 are provided on each support member 22, and the plurality of connecting portions 221 are spaced apart along the circumferential trajectory of the first direction X, so that a single support member 22 can form multiple sets of support cooperation with multiple surrounding support members 22 to realize the connection and support of a plurality of components to be fixed.

[0069] In some embodiments, the fixing structure further includes a housing body 30, and an accommodation cavity 31 is formed inside the housing body 30. The mounting member 10 and the support assembly 20 are both located inside the accommodation cavity 31. Taking a PCB board as an example, after the PCB board is fixed, a temperature and humidity experiment may be carried out, and it is necessary to place the PCB board inside a cavity to complete the detection of the PCB board. Therefore, the fixing structure may further include a housing body 30, an accommodation cavity 31 is formed inside the housing body 30, the mounting member 10 and the support assembly 20 are both located inside the accommodation cavity 31, and the housing body 30 wraps around the outer peripheral side of the PCB board, which can provide a certain protection for the PCB board.

In particular, as long as there is no structural conflict, the technical features mentioned in each embodiment can be combined in any way.
