[0028] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] In related technologies, cable management systems within server chassis include mounting brackets and multiple cable holders, each used to secure cables. However, the fixed positions of the cable holders on the mounting brackets prevent adjustment based on varying cable layout requirements, resulting in poor flexibility in the cable management system. When arranging cable management systems within server chassis of different sizes, the fixed positions of the cable holders on the mounting brackets easily lead to problems such as cable stretching, bending, or stacking, resulting in messy cable routing, affecting airflow within the chassis, and consequently impacting heat dissipation.

[0030] Based on this, this application proposes a cable fixing device and an electronic device to solve the technical problem that the cable fixing position in the cable fixing device is not adjustable, resulting in poor usage flexibility. The structure of the cable fixing device is described below with reference to the accompanying drawings.

[0031] like Figure 1 and Figure 2 As shown, the cable fixing device according to an embodiment of this application includes a mounting bracket 100 and at least one cable fixing mechanism. The cable fixing mechanism includes a locking adjustment structure 200 and a cable fixing structure 300, the cable fixing structure 300 being used to connect cables.

[0032] The locking adjustment structure 200 includes a mounting base 210, a locking element 220, and a first driving element 230. A cable fixing structure 300 is connected to the mounting base 210, which is movable relative to the mounting frame 100 along a first direction. The locking element 220 is disposed on the mounting base 210 and at least partially connected to the mounting frame 100. The first driving element 230 drives the locking element 220 to move, thereby moving the mounting base 210 along the first direction and locking the mounting base 210 onto the mounting frame 100.

[0033] The cable fixing device of this application embodiment features a mounting base 210 that can move relative to the mounting frame 100 along a first direction. A locking member 220 connected to the mounting frame 100 is provided on the mounting base 210. The locking member 220, in conjunction with a first driving member 230, moves in motion, thereby locking the mounted base 210 onto the mounting frame 100 while simultaneously moving it along the first direction. Therefore, the position of the cable fixing structure 300 can be adjusted on the mounting frame 100 according to actual wiring requirements, thus solving the technical problem of poor flexibility in the use of the cable fixing structure 300 in related technologies.

[0034] Furthermore, when the cable fixing device in this embodiment is installed inside the electronic device, the flexible adjustment of the cable fixing mechanism facilitates neat and orderly cable routing, thereby optimizing space utilization, avoiding space stacking and waste, and improving the heat dissipation efficiency of the electronic device, reducing the problem of overheating. In addition, the cable fixing device of this application also has good compatibility, which helps to reduce the safety hazards caused by cable compression or stretching, and overall enhances the flexibility and security of cable management for electronic devices such as servers.

[0035] The mounting bracket 100 in this embodiment is a basic support component for supporting and constraining the cable fixing mechanism. The function of the mounting bracket 100 is to provide a stable mounting platform for one or more cable fixing mechanisms and to provide guidance and force foundation for the movement of the mounting base 210 in the first direction.

[0036] The cable fixing mechanism in this embodiment is a functional component for clamping, guiding, or accommodating cables. In the locked state, the cable fixing mechanism maintains the cable's stable position, and in the unlocked state, it allows the cable to move relative to the mounting bracket 100 along a first direction to adapt to different cabling requirements, different server equipment interface locations, and different cable bundle diameters. In specific implementations, the number of cable fixing mechanisms can be determined according to usage requirements and is not limited to... Figure 1 The four shown.

[0037] An exemplary structure of the mounting bracket 100 in this application embodiment is as follows: Figure 1 As shown, the mounting bracket 100 has a length direction and a width direction. In this embodiment of the application, the first direction ( Figure 1 The X direction shown can specifically be the length direction of the mounting bracket 100.

[0038] In one possible implementation, such as Figure 2 , Figure 3 and Figure 7 As shown, the mounting bracket 100 is provided with a rack 130, which extends along a first direction. The locking member 220 is a gear rotatably mounted on the mounting base 210. The gear meshes with at least a portion of the rack 130. The first driving member 230 is used to drive the gear to rotate, thereby moving the mounting base 210 along the first direction and locking the mounting base 210 on the mounting bracket 100.

[0039] Among them, the rack 130 is a linear meshing member set on the mounting bracket 100. The rack 130 is arranged along the first direction and forms a continuous tooth profile to provide a stable meshing track for the gear, so that the mounting base 210 can move smoothly along the first direction during the adjustment process and form a reliable lock at the target position.

[0040] A gear is a meshing transmission component rotatably mounted on a mounting base 210. The gear has teeth and can rotate about its own axis, primarily used to mesh with a rack 130. It converts the rotational motion output by the first drive member 230 into linear displacement of the mounting base 210 relative to the mounting bracket 100, while maintaining its current position by means of meshing resistance after the drive stops. The gear is rotatably mounted on the mounting base 210 via a shaft. The gear axis is generally perpendicular to the extension direction of the rack 130, and the tooth surfaces maintain at least partial overlap with the rack 130, thus allowing it to roll along the rack 130 during rotation and achieve smooth transmission.

[0041] Here, through the meshing of the gear and rack 130, when the first driving member 230 drives the gear to rotate, the gear rolls along the rack 130, thereby driving the mounting base 210 and the entire cable fixing mechanism to move along the first direction. When the first driving member 230 stops rotating, the meshing between the gear and rack 130 and the holding torque of the first driving member 230 allow the mounting base 210 to remain at any desired position and be locked by the gear and rack 130, eliminating the need for an additional locking structure to lock the mounting base 210. By employing the gear and rack 130, this application achieves both arbitrary position adjustment of the cable fixing structure 300 along the length of the mounting bracket 100 and ensures reliable locking after adjustment, thus improving the structural flexibility and reliability of the cable fixing device.

[0042] In terms of specific structure, as an example of arrangement, such as Figure 3 As shown, a mounting groove 140 extending in a first direction is provided on one side of the mounting bracket 100. A rack 130 is disposed on one side of the mounting groove 140, and a mounting base 210 is located outside the opening of the mounting groove 140. At least a portion of the gear is located within the mounting groove 140. This arrangement helps to reduce the exposure of the gear and rack 130 structures, thereby reducing the space occupied by the entire cable fixing device.

[0043] In addition, the rack 130 in this embodiment can be a straight rack. In different embodiments, it can also be made of hardened steel, alloy steel, surface-hardened aluminum alloy, or high-strength engineering plastic, depending on the installation space and stress requirements, to balance wear resistance, load-bearing capacity, and ease of assembly. The module, tooth height, and tooth width of the rack 130 should match the gear. Typically, its effective length should at least cover the adjustment stroke required by the mounting base 210, and the tooth height is generally about two to two and a half times the module to ensure stable meshing and reduce the problem of tooth slippage.

[0044] Gears can be cylindrical spur gears or bevel gears, and the materials can be carburized steel, alloy steel, powder metallurgy parts, or engineering plastics to meet different requirements for strength, wear resistance, and manufacturing cost. The gear diameter should match the module of the rack 130, and the tooth width is usually basically the same as or slightly larger than the tooth width of the rack 130 to ensure full meshing. The meshing depth is generally controlled to be more than 60% of the full tooth height to improve transmission efficiency and locking stability.

[0045] In one possible implementation, such as Figure 5As shown, a worm gear 240 is rotatably mounted on the mounting base 210. A worm wheel 221, meshing with the worm gear 240, is connected to the shaft of the gear. The first driving member 230 drives the gear to rotate via the worm gear 240 and the worm wheel 221. The arrangement of the worm wheel 221 and worm gear 240 facilitates the first driving member 230 in driving the gear. Furthermore, the transmission between the worm gear 240 and the worm wheel 221 has a reverse self-locking characteristic. When the first driving member 230 stops working, even if the gear is subjected to a reverse force from the rack 130 (such as cable tension or vibration), the reverse force cannot drive the worm gear 240 to rotate via the worm wheel 221. Therefore, the mounting base 210 can automatically maintain its current position, exhibiting good locking reliability.

[0046] Specifically, the first driving component 230 is a motor, which is connected to one side of the mounting base 210. Both the worm gear 240 and the worm wheel 221 are rotatably mounted within the mounting base 210. The worm gear 240 is connected to the motor output shaft, and the gear axis is perpendicular to the first direction. The worm wheel 221 is connected to the side of the rotating shaft near the mounting base 210 and meshes with the worm gear 240. This cooperation between the worm wheel 221 and the worm gear 240 makes the layout of the entire structure on the mounting base 210 more compact, thus facilitating the arrangement of cable fixing devices within the server chassis. Of course, besides using the worm wheel 221 and worm gear 240 for transmission, other transmission structures can also be used, as long as the power of the first driving component 230 can be transmitted to the gear.

[0047] In one possible implementation, such as Figure 1 , Figure 2 and Figure 7 and Figure 8 As shown, the mounting bracket 100 includes a first bracket 110 and a second bracket 120. The second bracket 120 is movably mounted on the first bracket 110 along a first direction. The rack 130 includes a first rack 131 mounted on the first bracket 110 and a second rack 132 mounted on the second bracket 120. The first rack 131 and the second rack 132 at least partially overlap in the first direction. The mounting base 210 is movable relative to the first bracket 110 or the second bracket 120 along a second direction, so that the gears mesh with the first rack 131 and the second rack 132 to lock the second bracket 120 onto the first bracket 110, or so that the gears mesh with the first rack 131 to release the locking of the second bracket 120 onto the first bracket 110. The second bracket 120 is movable along the first direction, and the second direction intersects with the first direction.

[0048] Here, by setting up a relatively movable first frame 110 and a second frame 120, the overall length of the mounting bracket 100 can be flexibly adjusted according to the actual size of the server chassis or the requirements of the cabling span, without the need to replace different specifications of fixing devices, thereby further improving the versatility and adaptability of the cable fixing device. Using the same gear, by changing the meshing object of the gear along the second direction, locking (the gear meshes with both the first rack 131 and the second rack 132) or unlocking (the gear meshes only with the first rack 131) can be achieved. This design requires no additional locking mechanism, resulting in a simple structure and low cost. The second direction is parallel to the axis of the gear, specifically... Figure 5 The direction indicated by the middle arrow is Y.

[0049] When the length of the mounting bracket 100 needs to be adjusted, simply move the mounting base 210 in the second direction to engage the gear with the first rack 131 and disengage it from the second rack 132 (the gear is in the unlocked state). At this time, the second frame 120 can move relative to the first frame 110 in the first direction. After the second frame 120 is in place, move the mounting base 210 in the opposite direction in the second direction to re-engage the gear with both racks 130 simultaneously (the gear is in the locked state).

[0050] Specifically, such as Figure 1 , Figure 9 and Figure 10 As shown, both the first frame 110 and the second frame 120 are elongated, with the second frame 120 located on one side of the first frame 110. The mounting groove 140 is defined between the first frame 110 and the second frame 120. A first rack 131 is disposed on the side of the first frame 110 facing the second frame 120, and one end of a second rack 132 is connected to the second frame 120, with the second rack 132 located on one side of the first rack 131. The second direction can specifically be the width direction of the rack 130.

[0051] like Figure 8 As shown, the fact that the first rack 131 and the second rack 132 at least partially overlap in the first direction means that the first rack 131 and the second rack 132 have overlapping portions in the projection range along the first direction. Specifically, when the multiple overlapping teeth on the first rack 131 and the second rack 132 are aligned, the gear meshes with the first rack 131 and the second rack 132 simultaneously.

[0052] In one possible implementation, such as Figure 7 and Figure 8As shown, the first frame 110 is provided with at least two first racks 131 arranged at intervals, and a second rack 132 is slidably disposed between two adjacent first racks 131. Here, by providing at least two first racks 131 arranged at intervals, the gear simultaneously meshes with two first racks 131 and one second rack 132 in the locked state (i.e., simultaneously meshes with at least three racks 130). Compared to meshing with only one first rack 131 and one second rack 132, this gear meshing structure with multiple racks 130 significantly increases the number of meshing points and contact area of ​​the gear, making the gear more evenly stressed, able to withstand greater cable tension and vibration impact, and improving the reliability and stability of the locking mechanism.

[0053] In addition, such as Figure 8 As shown, the second rack 132 is slidably disposed between two adjacent first racks 131, such that both sides of the second rack 132 are restricted by the two first racks 131 respectively. This effectively ensures that the second rack 132 moves only relative to the first racks 131 along the first direction, guaranteeing the motion accuracy of the second rack 132 relative to the first racks 131 and making the alignment of the two in the vertical direction more stable. When the gear releases the lock on the second rack 132, the gear meshes with the first rack 131 located on the side of the second rack 132 facing the mounting base 210.

[0054] In one possible implementation, such as Figure 3 , Figure 4 and Figure 7 As shown, at least one of the first frame 110 and the second frame 120 is provided with a slide rail 145. The slide rail 145 extends along a first direction. The locking adjustment structure 200 includes a slider 250, which is slidably disposed on the slide rail 145. The mounting base 210 is slidably connected to the slider 250 along a second direction.

[0055] Here, by setting the slide rail 145 and the sliding member 250, the overall movement of the cable fixing mechanism along the first direction and the partial movement of the mounting base 210 along the second direction are decoupled. The sliding member 250 serves as the sliding guide along the first direction, and the mounting base 210 slides on the sliding member 250 along the second direction. The two do not interfere with each other, which facilitates independent control of the gears to meet different adjustment needs.

[0056] Specifically, the slide rail 145 is a track component used for linearly guiding the sliding component. The slide rail 145 limits the smooth reciprocating movement of the slider 250 only along a first direction. The slide rail 145 is respectively disposed on the side of the first frame 110 and the second frame 120 facing the mounting base 210. The slide rail 145 restricts the slider 250 and the mounting base 210 connected to the slider 250 to move only along the first direction.

[0057] The slider 250 is a movable guide component that cooperates with the slide rail 145. The function of the slider 250 is to support the mounting base 210 and convert the movement of the mounting base 210 into linear displacement along a first direction, thereby providing an adjustable base support for the locking adjustment structure 200. The slider 250 is slidably mounted on the slide rail 145. Specifically, the slider 250 can cooperate with the slide rail 145 in the form of a slider, a sliding plate, a small carriage with wheels, etc. Figure 4 As shown, the slider 250 can be a block. For example, if there are two slide rails 145, there are also two sliders 250. The mounting base 210 is connected to the two sliders 250, which helps to improve the stability of the mounting base 210 during movement. It is understood that the number of slide rails 145 and sliders 250 can be increased or decreased according to usage requirements.

[0058] In one possible implementation, such as Figure 3 As shown, the slider 250 is provided with a guide post 251 extending in the second direction, the mounting base 210 is slidably disposed on the guide post 251, and a first elastic member 260 is provided between the guide post 251 and the mounting base 210. The first elastic member 260 is used to apply a force toward the slider 250 to the mounting base 210.

[0059] Here, the guide post 251 extends along the second direction, and the mounting base 210 is slidably disposed on the guide post 251. This restricts the degree of freedom of the mounting base 210 in directions other than the second direction, ensuring that the mounting base 210 does not wobble or twist during sliding along the first direction, thereby guaranteeing the engagement effect between the gear and the rack 130. The first elastic member 260 applies a force toward the sliding member 250 to the mounting base 210. In the locked state, the force applied by the first elastic member 260 can press the mounting base 210 against the sliding member 250, so that the gear is stably held in a position where it is simultaneously engaged with the first rack 131 and the second rack 132, preventing the gear from disengaging due to vibration or accidental impact, thereby improving the reliability of the gear and rack 130 engagement lock.

[0060] In terms of specific structure, such as Figure 3 and Figure 5 As shown, a sliding member 250 has two guide posts 251 arranged at intervals, and a mounting base 210 has guide sleeves 211 through which the two guide posts 251 pass respectively. A first elastic member 260 is a spring sleeved on the guide posts 251, which helps ensure the stability of the first elastic member 260 during use. The first elastic member 260 is located on the side of the mounting base 210 away from the sliding member 250. When the mounting base 210 moves away from the sliding member 250 in a second direction, the first elastic member 260 is compressed and stores energy. Of course, in specific implementations, the number and position of the guide posts 251 and guide sleeves 211 can be determined according to usage requirements.

[0061] In one possible implementation, such as Figure 5 As shown, the guide post 251 is provided with a limiting part 252, which is located on the side of the mounting base 210 away from the sliding member 250. The first elastic member 260 is located between the mounting base 210 and the limiting part 252. By providing the limiting part 252, the arrangement of the first elastic member 260 is facilitated, thereby helping to ensure the reliability of the mounting base 210 in use.

[0062] As one structural example of the limiting part 252, such as Figure 5 As shown, the limiting part 252 includes a limiting protrusion ring disposed on the guide post 251 as it moves away from the sliding member 250. The limiting protrusion ring has a large contact area with the first elastic member 260, which helps to ensure the stability of the first elastic member 260 in use.

[0063] In one possible implementation, such as Figure 4 , Figure 5 and Figure 6 As shown, the locking adjustment structure 200 includes a second drive member 270, which is used to drive the mounting base 210 to move relative to the sliding member 250 in a second direction, so that the gear engages with the first rack 131 and the second rack 132 to lock the second frame 120 onto the first frame 110, or to engage the gear with the first rack 131 to release the lock of the second frame 120 onto the first frame 110.

[0064] Here, by setting an independent second driving component 270, the active switching of the gear engagement state is realized. During operation, the mounting base 210 can be driven to move along the second direction as needed, so that the gear switches between a locked state "engaged with both racks 130 simultaneously" and an unlocked state "engaged only with the first rack 131". The second driving component 270 can drive the mounting base 210 to the locked position and the unlocked position. In the locked position, the gear engages with the first rack 131 and the second rack 132 simultaneously. In the unlocked position, the gear engages only with the first rack 131.

[0065] When the overall length of the mounting bracket 100 needs to be adjusted, the second drive mechanism 270 is activated to move the mounting base 210 to the unlocked position, allowing the second frame 120 to move freely. After the second frame 120 is in place, the second drive mechanism 270 is activated again to move the mounting base 210 to the locked position. The entire process requires no disassembly of any parts and no manual gear shifting, offering the advantages of simple and quick operation.

[0066] In terms of specific structure, such as Figure 6As shown, the second driving member 270 is a cylinder, and the first driving member 230 is disposed on the other side of the mounting base 210 relative to the guide post 251. The second driving member 270 is mounted on the mounting base 210, and the power output end of the second driving member 270 can pass through the mounting base 210 and connect to another sliding member 250. When the power output end of the second driving member 270 extends, it drives the mounting base 210 to move away from the sliding member 250 along the second direction, driving the gear to move synchronously until the gear only meshes with the first rack 131. At this time, the gear releases the lock on the second rack 132, and the second frame 120 can move relative to the first frame 110 along the first direction, thereby adjusting the length of the entire mounting frame 100.

[0067] Once the second mounting bracket 100 is in place, the retraction of the power output end of the second drive member 270 and the action of the first elastic member 260 cause the mounting base 210 to move in the direction close to the sliding member 250 until the gear and the first rack 131 and the second rack 132 are all engaged, thus locking the second frame 120 back onto the first frame 110.

[0068] In one possible implementation, such as Figure 7 As shown, the locking adjustment structure 200 also includes a length adjustment section 280. The first frame 110 and the second frame 120 are both connected to the length adjustment section 280. The length adjustment section 280 is used to drive one of the first frame 110 and the second frame 120 to move relative to the other in a first direction.

[0069] Here, by providing a length adjustment unit 280, the second frame 120 can be moved relative to the first frame 110 along a first direction during adjustment, thereby changing the overall length of the mounting bracket 100. This allows the same cable fixing device to adapt to server chassis of different sizes or cabling areas of different spans without replacing the mounting bracket 100, thus further improving the versatility and adaptability of the cable fixing device.

[0070] In one possible implementation, such as Figure 7 As shown, the length adjustment unit 280 includes a third drive member 281 and a lead screw 282. The lead screw 282 is rotatably mounted on the first frame 110. The lead screw 282 extends along a first direction and is threadedly connected to a threaded engagement part on the second frame 120. The third drive member 281 is used to drive the lead screw 282 to rotate, so as to drive the second frame 120 to move relative to the first frame 110 along the first direction.

[0071] Here, the third drive member 281 and the lead screw 282 cooperate to improve the convenience of adjusting the position of the second frame 120 relative to the first frame 110. By controlling the rotation angle or number of rotations of the third drive member 281, the moving distance of the second frame 120 can be precisely controlled, which helps to ensure the alignment accuracy of the first rack 131 and the second rack 132, thereby meeting the locking requirement that the gears simultaneously mesh with the first gear and the second gear.

[0072] In terms of specific structure, such as Figure 1 and Figure 9 As shown, a first protrusion 111 is provided on one side of the end of the first frame 110. The end of the second frame 120 facing the first protrusion 111 can abut against the first protrusion 111. Here, the first protrusion 111 is used to limit the displacement of the second frame 120 towards the first protrusion 111. One end of the lead screw 282 is rotatably mounted on the first protrusion 111. A connecting groove is provided on the second frame 120, and the lead screw 282 is inserted into the connecting groove. The threaded part is specifically a nut sleeve connected to the opening of the connecting groove, and the lead screw 282 passes through the nut sleeve and is located in the connecting groove.

[0073] Specifically, such as Figure 7 As shown, when the third driving member 281 drives the lead screw 282 to rotate in the forward direction, the second frame 120 moves away from the first frame 110 in the first direction through the nut sleeve, and the length of the mounting bracket 100 increases at this time. When the third driving member 281 drives the lead screw 282 to rotate in the reverse direction, the second frame 120 moves closer to the first frame 110 in the first direction through the threaded sleeve 283, and the length of the mounting bracket 100 decreases at this time.

[0074] In addition, such as Figure 10 As shown, a second protrusion 121 is provided at the end of the second frame 120 away from the first frame 110, and the second protrusion 121 and the first protruding ring are arranged opposite each other in a first direction. When the second frame 120 moves to abut against the first protrusion 111, the second protrusion 121 also abuts against the end of the first frame 110.

[0075] In another possible implementation, the positions of the lead screw 282 and the threaded sleeve 283 can be interchanged, that is, the lead screw 282 can be rotatably mounted on the second frame 120, and the threaded sleeve 283 can be mounted on the first frame 110. In this case, the third drive member 281 can be mounted on the second frame 120 to drive the first frame 110 to move relative to the second frame 120, thereby adjusting the length of the entire mounting bracket 100.

[0076] In this embodiment, the third drive member 281 outputs driving force and causes the lead screw 282 to start rotating. Since the lead screw 282 is arranged along the first direction and is threadedly connected to the threaded mating part on the second frame 120, the rotational motion of the lead screw 282 is converted into the linear displacement of the threaded mating part along the axial direction, thereby driving the second frame 120 to move smoothly relative to the first frame 110 along the first direction.

[0077] After the cable fixing device is installed inside the cabinet, the operator can pre-adjust the position of the second rack 120 according to the equipment depth, cable length, and cabling path. During subsequent maintenance or expansion, the position of the second rack 120 can also be finely adjusted by driving the third drive unit 281 again, so that the overall device can adapt to different server models, different installation spacing, and different cable distribution requirements.

[0078] Because the lead screw 282 transmission features controllable displacement, good repeatability, and stable load-bearing capacity, the second frame 120 can maintain a relatively stable movement during adjustment, reducing positional deviations caused by manual pushing or pulling or gap wobbling. Furthermore, the threaded pair itself has a certain degree of self-locking, allowing it to maintain its current length position after the drive stops, preventing it from automatically retracting. The length adjustment section 280 improves the adaptability of the cable fixing device within the cabinet, resulting in neater cable routing and facilitating the provision of reasonable airflow channels. This reduces the adverse effects of cable stacking on heat dissipation and facilitates subsequent disassembly and maintenance. It should be understood that the above example is for illustrative purposes only and is not limiting.

[0079] In one possible implementation, such as Figure 9 As shown in the embodiment of this application, the cable fixing device further includes a position detection component 290, which is disposed on the first frame 110 or the second frame 120 and is used to detect the alignment of the first rack 131 and the second rack 132 in the overlapping area of ​​the two.

[0080] Here, the alignment of the first rack 131 and the second rack 132 in their overlapping area refers to whether their tooth grooves are aligned in the overlapping area in the first direction. If the tooth grooves of the first rack 131 and the second rack 132 are misaligned, the gear cannot simultaneously enter the tooth grooves of both racks 130, resulting in the gear failing to lock or becoming stuck in mesh. By detecting the alignment in real time through the position detection element 290, it can be determined whether the current conditions for simultaneous meshing of the first rack 131 and the second rack 132 can be met.

[0081] In addition, the position detection component 290 is electrically connected to the third drive component 281, which is used to adjust the position of the second frame 120 according to the detection result of the position detection component 290, so that the first rack 131 and the second rack 132 are aligned in the overlapping area.

[0082] In a specific arrangement, the position detection component 290 can be installed on the side wall of the first frame 110, the side wall of the second frame 120, or the inner side near the mounting area of ​​the rack 130. The position detection component 290 can be an infrared sensor, etc., used to detect the movement distance of the second frame 120 relative to the first frame 110. The infrared sensor includes an infrared transmitter and a receiver, both mounted on the first frame 110 or the second frame 120. The detection optical path of the infrared sensor points to the side or tooth tip of the second rack 132, used to collect the displacement of the second rack 132 in real time.

[0083] As the second frame 120 moves along the first direction, the second rack 132 moves accordingly. An infrared sensor emits infrared light and receives reflected signals, calculating the distance the second rack 132 has moved relative to its initial position using changes in light intensity or the time-of-flight method. This distance signal is transmitted in real-time to an external controller. The third drive unit 281 is also electrically connected to the controller, and the position detection unit 290 is electrically connected to the third drive unit 281 via the controller. The controller stores the position parameters (i.e., the target position) of the second frame 120 when the first rack 131 and the second rack 132 are perfectly aligned in the vertical direction.

[0084] During the position adjustment of the second frame 120, the controller receives the movement distance signal fed back by the infrared sensor and compares it with the target position. If there is a deviation between the actual position and the target position, the controller controls the third drive component 281 to drive the lead screw 282 to rotate forward or backward, making fine adjustments to the position of the second frame 120 until the actual position matches the target position. When the second frame 120 reaches the target position, the teeth on the first rack 131 and the second rack 132 are exactly aligned in the vertical direction (tooth groove to tooth groove). At this time, after the gear moves along the second direction, it can simultaneously mesh with the first rack 131 and the second rack 132.

[0085] The cable fixing device in this embodiment integrates three major functions: movement of the cable fixing mechanism, locking of the length of the mounting bracket 100, and state switching, through the engagement of a single gear with racks 130 on both frames. When the gear meshes with both the first rack 131 and the second rack 132, it not only constrains the relative movement of the two frames and locks the length of the mounting bracket 100, but also drives the entire cable fixing mechanism to move along the frames when the gear rotates. When the gear meshes with only the first rack 131 in the second direction, the second frame 120 is released, allowing adjustment of the overall span of the mounting bracket 100. This "one gear, multiple uses" structural design highly integrates movement, locking, and unlocking, eliminating the need for additional locking devices, significantly simplifying the mechanical structure, and improving operational convenience and locking reliability.

[0086] The stable meshing structure of the gear and rack 130 in this embodiment of the application is beneficial to enhancing the overall structural strength of the cable fixing device, making the cable fixing device more stable when carrying the cable, and avoiding uneven force or swaying of the cable due to loosening or misalignment.

[0087] Furthermore, this application employs a layout where two first racks 131 clamp the second rack 132, allowing the gear to simultaneously mesh with at least three racks 130 in the locked state. This ensures symmetrical force distribution and smooth guidance, effectively preventing swaying and jamming during long-stroke movements. Combined with the position detection element 290 and the controller, a closed-loop feedback system is formed, automatically correcting the alignment of the two racks 130 in the overlapping area to ensure smooth gear engagement with each locking action. Therefore, this embodiment of the application enhances the adaptability and flexibility of the cable fixing device.

[0088] It should be noted that when there are multiple cable fixing mechanisms in this embodiment, the spacing between any two adjacent cable fixing mechanisms can be adjusted. However, when locking the second frame 120, the gear in at least one cable fixing mechanism can simultaneously mesh with the first rack 131 and the second rack 132. Of course, the number of gears meshing with the first rack 131 and the second rack 132 in the locked state of the second frame 120 can also be adjusted according to usage requirements.

[0089] In one possible implementation, such as Figure 5 and Figure 11 As shown, the cable fixing structure 300 includes a fixing base 310 and a fixing plate 320. The fixing base 310 is connected to the mounting base 210, and both ends of the fixing plate 320 are connected to the fixing base 310. A cable mounting hole 330 is formed between the fixing plate 320 and the fixing base 310. Here, the cable mounting hole 330 is defined between the fixing plate 320 and the mounting base 210, which facilitates the arrangement of cables between the fixing base 310 and the fixing plate 320, and achieves the effect of fixing the cables.

[0090] The fixing plate 320 is a plate-shaped component used to cover, limit, and clamp cables. When it cooperates with the fixing base 310, it forms a cable-accommodating space, thereby ensuring that the cable remains stably laid out after installation. One end of the fixing plate 320 is hinged to the fixing base 310, allowing the fixing plate 320 to rotate relative to the fixing base 310 around the hinge axis to open or close, facilitating the insertion or removal of cables during assembly, maintenance, or cable replacement. The other end of the fixing plate 320 is detachably connected to the fixing base 310 via a locking part 340, ensuring that the fixing plate 320 forms a reliable constraint relationship with the fixing base 310 when closed, preventing the cable from falling out of its fixed position due to equipment vibration, pulling, or environmental disturbance.

[0091] Because the two ends of the fixing plate 320 are connected to the fixing base 310 respectively, and together with the fixing base 310 form the cable mounting hole 330, the cable is less likely to move laterally or overlap locally under restricted conditions, thereby reducing the problems of excessive cable pulling, twisting, and bending. Based on the above process, it can be seen that while ensuring cable support strength, the neatness of the cabling is improved, and the adjustable cable mounting hole 330 enhances the adaptability to different cabinet layouts and different cable specifications, thus facilitating subsequent maintenance and expansion operations. It should be understood that the above example is for demonstration purposes only and is not limiting.

[0092] In terms of specific structure, such as Figure 1 and Figure 11 As shown, the top of the mounting base 310 is connected to the end of the mounting base 210 away from the mounting bracket 100. A fixing plate 320 is connected to the end of the mounting base 310 away from the mounting base 210. The fixing plate 320 is arc-shaped, and a semi-circular cable mounting hole 330 is defined between the fixing plate 320 and the mounting base 310. This separates cable fixing from the position adjustment of the mounting base 210, and the cable fixing structure 300 can move synchronously with the mounting base 210.

[0093] The fixing plate 320 can be a long strip, an arc-shaped pressure plate, or a composite plate with reinforcing ribs. In one possible embodiment, the fixing plate 320 can be made of metal to improve load-bearing capacity. In another possible embodiment, it can be made of engineering plastic to reduce weight and facilitate molding. In yet another exemplary embodiment, it can be made of elastic composite material to improve fit and cushioning performance when closed.

[0094] The dimensions of the fixing plate 320 typically need to match the opening width of the fixing base 310. Its length should at least cover the effective span of the cable mounting hole 330, and after closure, it should form sufficient contact surface with the outer periphery of the cable to ensure uniform clamping. The thickness of the fixing plate 320 should be kept as small as possible while meeting rigidity requirements to avoid occupying excessive installation space. The thickness of the fixing plate 320 can be adjusted according to the number of cables, wire diameter, and structural strength of the fixing base 310. It should be understood that the above example is for illustrative purposes only and is not a limitation.

[0095] It should be noted that the shape of the fixing plate 320 can be arc-shaped, U-shaped, C-shaped, or other shapes. The shape of the cable mounting hole 330 defined between the fixing base 310 and the fixing plate 320 can be semi-circular, circular, rectangular, or other geometric shapes. One cable mounting hole 330 can fix one, two, or more cables. In specific implementations, the number of cables within the cable mounting hole 330 can be determined according to usage requirements.

[0096] In one possible implementation, such as Figure 11As shown, one end of the fixing plate 320 is hinged to the fixing base 310, and the other end of the fixing plate 320 is detachably connected to the fixing base 310 via a locking part 340. With this configuration, the operator only needs to insert the cable into the cable mounting hole 330 and then lock the fixing plate 320 onto the fixing base 310 via the locking part 340. When it is necessary to remove the cable, the locking part 340 is engaged to lock the fixing plate 320. This configuration simplifies cable installation and replacement operations.

[0097] Because one end of the fixing plate 320 is hinged and the other end is detachably locking, the fixing plate 320 does not need to be completely removed from the fixing base 310 when switching between opening and closing. This reduces the loss of disassembly and assembly parts and improves maintenance efficiency. Simultaneously, the locking part 340 applies constraint to the end of the fixing plate 320 after closing, creating a relatively stable force relationship between the fixing plate 320 and the fixing base 310. This reduces the probability of cable loosening during long-term use and keeps the cables neatly distributed inside the cabinet. Based on the above analysis, a balance is achieved between reliable clamping and convenient maintenance while ensuring quick cable insertion and removal. This improves the adaptability of the cable fixing device to different cabling scenarios and helps reduce problems such as cable sheath wear and uneven stress on interfaces. It should be understood that the above example is for demonstration purposes only and is not limiting.

[0098] In one possible implementation, such as Figure 11 As shown, the locking part 340 includes a locking member 341 and a second elastic member 342. The locking member 341 is slidably disposed on the fixed base 310. The second elastic member 342 is connected between the locking member 341 and the fixed base 310. The second elastic member 342 is used to drive the locking member 341 to move toward the fixed plate 320 so as to lock the fixed plate 320 on the fixed base 310.

[0099] Here, the second elastic element 342 applies a force towards the fixed plate 320 to the locking element 341. When the fixed plate 320 is engaged in place on the fixed seat 310, the locking element 341 automatically slides into the fixed plate 320 under the elastic force of the second elastic element 342, locking the fixed plate 320 onto the fixed seat 310. The locking process can be completed without manual operation of the locking part 340, thus improving the convenience of locking the fixed plate 320. Under vibration or external force, the second elastic element 342 always maintains the engagement state between the locking element 341 and the fixed plate 320. Only by manually overcoming the elastic force of the first elastic element 260 to pull the locking element 341 away from the fixed plate 320 can the fixed plate 320 be unlocked.

[0100] In this embodiment, the locking member 341 can be understood as a movable locking element disposed on the fixed base 310, which is used to form a fastening constraint on the fixed plate 320 when the fixed plate 320 is closed and close to the fixed base 310. The second elastic member 342 is an elastic member that provides a restoring force to the locking member 341. Its function is to keep the locking member 341 in a pre-tightened state in the direction of the fixed plate 320 when there is no external force, thereby ensuring that the fixed plate 320 can be stably kept in the locked position.

[0101] In terms of specific structure, such as Figure 12 As shown, a slot 350 is provided at the bottom of the fixing base 310, and a plug 360 is provided at the end of the fixing plate 320 away from the hinge end. When the fixing plate 320 is in the locked state, the plug 360 is inserted into the slot 350. A locking hole 361 is provided on the plug 360 along the sliding direction of the locking member 341. The locking member 341 is slidably disposed in a groove 370 on the fixing base 310, and the axis of the groove 370 is perpendicularly connected to the slot 350. One end of the locking member 341 can extend into the slot 350, and the other end extends out of the fixing base 310. The end of the locking member 341 away from the slot 350 forms a radially outwardly protruding flange. A second elastic member 342 is sleeved on the portion of the locking member 341 located on the fixing base 310. One end of the tension spring is connected to the flange, and the other end is connected to the outer wall of the fixing base 310.

[0102] In this embodiment of the application, the second elastic element 342 is pre-tightened. The pre-tightening amount and elastic force of the second elastic element 342 should match the opening resistance of the fixed plate 320. This ensures that the plate is not easily detached under vibration and that maintenance personnel can manually apply force to overcome the elastic force of the second elastic element 342 to unlock the plate when the fixed plate 320 needs to be opened.

[0103] In its natural state, the second elastic element 342 is in a contracted state, applying a pulling force towards the fixing seat 310 to the flange, thereby causing the locking element 341 to slide into the slot 350. When the fixing plate 320 is closed and the insert 360 is fully inserted into the slot 350, the locking hole 361 and the locking element 341 are perfectly aligned. Under the action of the second elastic element 342, the locking element 341 automatically inserts into the locking hole 361, locking the insert 360 in the slot 350. At this time, even if the cable pulls the fixing plate 320 upward, the insert 360 cannot come out of the slot 350.

[0104] The operator pulls the locking member 341 outward in the direction away from the slot 350, overcoming the pulling force of the second elastic member 342, so that the locking member 341 is disengaged from the locking hole 361. At this time, the insert block 360 is no longer constrained by the locking member 341, and the fixing plate 320 can be flipped open around the hinge axis, and the insert block 360 is pulled out from the slot 350.

[0105] In addition, such as Figure 11As shown in the embodiment of this application, a plurality of weight-reducing holes 321 can also be provided on the fixing plate 320. The plurality of weight-reducing holes 321 are arranged at intervals along the circumference of the fixing plate 320 and are arranged through the fixing plate 320 along the axial direction of the cable mounting hole 330. The plurality of weight-reducing holes 321 here can play a role in weight reduction. In addition, the weight-reducing holes 321 can also be used for cable arrangement. When wiring, the cable can be passed through the weight-reducing holes 321 to fix the cable. Of course, the number and position of the weight-reducing holes 321 can also be adjusted according to the usage requirements, provided that the structural strength requirements of the fixing plate 320 are met.

[0106] The length adjustment process of the cable fixing device provided in this application embodiment is as follows: In the initial state, the gear meshes simultaneously with the first rack 131 and the second rack 132, and the length of the mounting bracket 100 is fixed. If it is necessary to adjust the overall length of the mounting bracket 100 to accommodate different sized chassis, the second drive unit 270 is activated first, driving the mounting base 210 to move along the second direction, so that the gear moves to mesh with the first rack 131 and disengages from the second rack 132. At this time, the gear releases the lock on the second frame 120.

[0107] Subsequently, the first drive member 230 of the length adjustment unit 280 is activated, driving the lead screw 282 to rotate. The lead screw 282 pushes the second frame 120 to move away from the first frame 110 in the first direction through the threaded engagement part until the mounting frame 100 reaches the required overall span.

[0108] During the movement of the second frame 120, the position detection component 290 detects the movement distance of the second rack 132 in real time and feeds the detection signal back to the controller. The controller determines the deviation between the current actual position and the target position based on the preset target position (i.e., the position of the second frame 120 when the first rack 131 and the second rack 132 are completely aligned in the vertical direction).

[0109] If a deviation exists, the controller controls the first drive component 230 to make a slight adjustment, causing the second frame 120 to move until the actual position matches the target position. At this time, the first rack 131 and the second rack 132 are perfectly aligned in the vertical direction (tooth groove to tooth groove, tooth tip to tooth tip), and the gears can simultaneously and smoothly enter the tooth grooves of both racks 130. After confirming alignment, the controller controls the second drive component 270 to reverse its movement, driving the mounting base 210 to reset, so that the gears re-engage with the first rack 131 and the second rack 132 simultaneously, completing the adjustment and locking of the length of the mounting frame 100.

[0110] When it is necessary to adjust the position of the cable fixing mechanism on the mounting bracket 100, the first drive component 230 is activated, which drives the gear to rotate via the worm gear 240 and worm wheel 221. Since the gear meshes with the first rack 131 and the second rack 132, the rotation of the gear is converted into linear movement of the mounting base 210 and the sliding component 250 along the slide rail 145, thereby driving the overall movement of the cable fixing structure 300 and realizing flexible adjustment of the spacing between the cable fixing points. During the adjustment process, the gear is always meshed with at least one rack 130, so the movement is smooth and can be stopped and held at any time.

[0111] When clamping the cable, first pull the locking member 341 outward to overcome the pulling force of the second elastic member 342, causing the locking member 341 to exit from the locking hole 361 of the fixing plate 320. At this time, the fixing plate 320 can be rotated open around the hinge axis. Place the cable into the cable mounting hole 330 between the fixing base 310 and the fixing plate 320, then close the fixing plate 320, release the locking member 341, and the second elastic member 342 will automatically pull the locking member 341 into the locking hole 361, locking the fixing plate 320 onto the fixing base 310, thereby reliably fixing the cable.

[0112] The cable fixing device of this application embodiment helps to reduce the burden of manual adjustment, facilitates maintenance and upgrades, reduces cable damage or poor contact caused by improper operation, and enhances system safety and stability. In addition, the adjustable length design of the mounting bracket 100 improves the adaptability of the mounting bracket 100 in electronic devices of different specifications, and improves the neatness of cable management, heat dissipation performance and ease of operation.

[0113] This application provides an electronic device, including a housing and the cable fixing device described above, wherein the cable fixing device is disposed inside the housing.

[0114] Once the cable fixing device is installed inside the enclosure, the internal space can be directly utilized to organize and support cables between servers, power modules, switching modules, or storage modules, creating an integrated layout between the cable fixing device and the electronic equipment. This allows for cable fixing and adjustment within the enclosure according to the actual interface locations and wiring paths, resulting in more orderly cable crossings between devices and reducing dangling, stacking, and bending.

[0115] Because the cable fixing device itself has position adjustment and locking capabilities, it can adapt to different equipment specifications, installation heights, and cable quantities, thereby reducing the inconvenience of repeated disassembly and assembly during maintenance, making the cable stress more even and reducing the problem of loose connections. Therefore, it can improve the wiring order and heat dissipation conditions within the enclosure, enhance the operational stability of electronic equipment, and improve the convenience of subsequent maintenance.

[0116] In a specific arrangement, the first frame 110 on the mounting bracket 100 can be fixed to the box by bolts or other connecting structures. At this time, by adjusting the position of the second frame 120 relative to the first frame 110, the length of the mounting bracket 100 can be adjusted. And by the cooperation of gears and racks 130, the position of the cable fixing mechanism on the mounting bracket 100 can be adjusted.

[0117] It should be noted that electronic devices include, but are not limited to, servers, computers, communication equipment, industrial control cabinets, distribution boxes, and household appliances—any electronic device requiring cable management. Those skilled in the art can install cable fixing devices on appropriate mounting platforms according to the actual usage environment to solve the problem of messy cable routing.

[0118] The cable fixing device and electronic device provided in this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make several improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of this application.
