Description

[0002] A computer is a modern intelligent electronic device capable of automatically and rapidly performing large-scale numerical calculations and various information processing tasks according to pre-stored programs.

Industrial control computers (ICCs), as ruggedized and enhanced personal computers, can reliably operate as industrial controllers in industrial environments. Currently, ICCs mainly consist of an industrial chassis, a passive backplane, and various pluggable cards (such as CPU cards and I / O cards). Due to the complex operating environment of ICCs, vibration can easily cause the motherboard to detach or be damaged. In related technologies, installing vibration damping devices between the industrial chassis and the motherboard can reduce the impact of vibration on the motherboard to some extent. However, under extreme conditions, the damping effect of these devices on the motherboard is limited and cannot effectively protect it. Summary of the Invention

[0042] Example 1

[0043] like Figures 1 to 7As shown, this application provides a computer with physical shock absorption function, including a computer casing (not shown), two mounting strips 1, a computer motherboard 2, and multiple shock-absorbing mechanisms 3. Both mounting strips 1 are installed inside the computer casing. The computer motherboard 2 is disposed between the two mounting strips 1. Multiple shock-absorbing mechanisms 3 are hinged between the mounting strips 1 and the computer motherboard 2. Each shock-absorbing mechanism 3 includes a mounting suspension assembly 31, a motherboard suspension assembly 32, an intermediate suspension assembly 33, a universal joint 34, an overload protection assembly 35, and a shock-absorbing elastic structure 36. The mounting suspension assembly 31 is hinged to the mounting strips 1, the motherboard suspension assembly 32 is hinged to the computer motherboard 2, the intermediate suspension assembly 33 is sleeved on the outer periphery of the motherboard suspension assembly 32 and hinged to the mounting suspension assembly 31 via the universal joint 34, the overload protection assembly 35 is snapped onto the end of the motherboard suspension assembly 32 away from the computer motherboard 2, and the shock-absorbing elastic structure 36 is sleeved on the motherboard suspension assembly 32 and elastically abuts against the intermediate suspension assembly 33 and the overload protection assembly 35.

[0044] This application provides a computer with the ability to absorb physical impacts. A shock-absorbing mechanism 3 is installed between the computer motherboard 2 and the two mounting strips 1, which can prevent direct contact between the computer motherboard 2 and the computer casing, reducing the impact of vibration on the computer motherboard 2. Under the action of the universal joint 34, the mounting suspension assembly 31 and the intermediate suspension assembly 33 can rotate relative to each other in different directions, allowing the computer motherboard 2 to move or rotate relative to the computer casing. This reduces the impact of vibration on the computer motherboard 2 from different directions. Compared with the prior art, it can achieve universal shock absorption, with better shock absorption effect, thus effectively protecting the computer motherboard 2. Under the action of the overload protection component 35, when the impact force received by the shock-absorbing mechanism 3 exceeds a preset threshold, it can actively disconnect, severing the assembly between the computer motherboard 2 and the mounting strips 1, preventing damage to the computer motherboard 2 due to excessive impact force, and also effectively protecting the computer motherboard 2.

[0045] Optionally, the shock-absorbing elastic structure 36 is configured as a spring or a sheet.

[0046] In one embodiment of this application, please refer to Figures 1 to 7 The motherboard suspension assembly 32 includes a motherboard hinge rod 321 and a slot 322, with the slot 322 located at the end of the motherboard hinge rod 321 away from the computer motherboard 2. The overload protection assembly 35 includes a sleeve 351, a mounting bracket 352, and at least one snap-fit ​​element 353. The sleeve 351 is fitted onto the motherboard hinge rod 321, the mounting bracket 352 is mounted on the sleeve 351, and at least one snap-fit ​​element 353 is mounted on the sleeve 351 and the mounting bracket 352, and snaps into the slot 322 under the action of the mounting bracket 352.

[0047] With this configuration, under the action of the card slot 322, card sleeve 351, and mounting bracket 352, when the impact force received by the shock-absorbing mechanism 3 is less than a preset threshold, the locking piece 353 and the motherboard hinge rod 321 can be locked together, preventing the motherboard hinge rod 321 from detaching from the intermediate suspension assembly 33, ensuring stable assembly. With the cooperation of the shock-absorbing elastic structure 36, the impact of vibration on the computer motherboard 2 can be stably reduced. Under the action of the card slot 322, card sleeve 351, and mounting bracket 352, when the impact force received by the shock-absorbing mechanism 3 is greater than a preset threshold, the locking piece 353 and the motherboard hinge rod 321 can disengage, and the motherboard hinge rod 321 will detach from the intermediate suspension assembly 33, preventing the impact force from directly acting on the computer motherboard 2, thus effectively protecting the computer motherboard 2.

[0048] In one embodiment of this application, please refer to the following: Figures 1 to 7 The snap-fit ​​component 353 includes a snap-fit ​​rod 3531, a limiting boss 3532, and an overload elastic structure 3533. The snap-fit ​​rod 3531 passes through the sleeve 351 and the mounting bracket 352. The limiting boss 3532 is connected to the outer periphery of the snap-fit ​​rod 3531 and is located between the sleeve 351 and the mounting bracket 352. The overload elastic structure 3533 is sleeved on the snap-fit ​​rod 3531 and elastically abuts against the mounting bracket 352 and the limiting boss 3532.

[0049] With this configuration, under the action of the slot 322, the latching rod 3531, and the limiting boss 3532, the motherboard hinge rod 321 can cause the overload elastic structure 3533 to undergo elastic deformation when subjected to impact force. When the deformation of the overload elastic structure 3533 is less than the depth of the slot 322, it can prevent the latching rod 3531 from disengaging from the slot 322, thereby ensuring that the motherboard hinge rod 321 and the latching rod 3531 are stably maintained in the latched state. When the deformation of the overload elastic structure 3533 is equal to or greater than the depth of the slot 322, the latching rod 3531 disengages from the slot 322, thereby releasing the motherboard hinge rod 321 and the latching rod 3531 from the latched state. In summary, under the combined action of the motherboard hinge rod 321, slot 322, sleeve 351, mounting bracket 352, connecting rod 3531, limiting boss 3532, and overload elastic structure 3533, when the impact force acting on the sleeve 351 exceeds a preset threshold, the motherboard hinge rod 321 disengages from the overload protection component 35, thereby achieving overload protection and effectively protecting the computer motherboard 2. Furthermore, compared to related technologies, the overload protection component 35 is reusable, easy to maintain, and greatly improves ease of use.

[0050] Optionally, the cross-sectional shape of the slot 322 and the cross-sectional shape of the locking rod 3531 near the slot 322 are both set to be arc-shaped.

[0051] Optionally, the overload elastic structure 3533 is configured as a spring or a sheet.

[0052] In one embodiment of this application, see [reference] Figures 1 to 7 The mounting bracket 352 includes two mounting rings 3521, at least one connecting bracket 3522, and at least one retaining ring 3523. The two mounting rings 3521 are both mounted on the sleeve 351 and are located at both ends of the sleeve 351 in the axial direction. The at least one connecting bracket 3522 is connected to the two mounting rings 3521 and the end away from the mounting ring 3521 is connected to the retaining ring 3523. The at least one retaining ring 3523 is respectively sleeved on at least one snap-fit ​​rod 3531 and is set in a one-to-one correspondence with the at least one snap-fit ​​rod 3531.

[0053] With this configuration, the retaining ring 3523 can be fixed to the sleeve 351 by the two mounting rings 3521 and the connecting bracket 3522. This helps to improve the structural stability between the retaining ring 3523 and the sleeve 351, thereby stably limiting the overload elastic structure 3533. This prevents the overload elastic structure 3533 from coming off the locking rod 3531 and allows the overload elastic structure 3533 to be properly compressed, so that the overload protection component 35 can provide overload protection for the computer motherboard 2.

[0054] In one embodiment of this application, please refer to Figures 1 to 7 The intermediate suspension assembly 33 includes a sleeve plate 331, two intermediate suspension rods 332, and two oblong holes 333. The sleeve plate 331 is fitted onto the motherboard hinge rod 321. The two intermediate suspension rods 332 are both connected to the sleeve plate 331 and are located on the side of the sleeve plate 331 facing away from the computer motherboard 2. Each of them has an oblong hole 333 and is also hinged to a universal joint 34. The motherboard suspension assembly 32 also includes two sliding rods 326. The two sliding rods 326 are both connected to the outer periphery of the sleeve 351 and pass through the two oblong holes 333, with each oblong hole 333 corresponding to the other.

[0055] This design, after the mainboard hinge rod 321 and the locking rod 3531 are released from their locking state, prevents the retaining sleeve 351 from detaching from the intermediate suspension assembly 33 via the two sliding rods 326 and the two oblong holes 333. During reassembly and reuse, the user does not need to find or reinstall the retaining sleeve 351, greatly improving ease of use. The two intermediate suspension rods 332 enable hinged engagement with the universal joint 34.

[0056] In one embodiment of this application, please refer to the following: Figures 1 to 7The mounting suspension assembly 31 includes a mounting plate 311 and two mounting suspension rods 312. Both mounting suspension rods 312 are connected to the mounting plate 311 and are located on the side of the mounting plate 311 facing the computer motherboard 2, and are hinged to the universal joint 34.

[0057] With this configuration, the universal joint 34 can be hinged to the two mounting suspension rods 312. In summary, the universal joint 34 can be hinged to both intermediate suspension rods 332 and the two mounting suspension rods 312 simultaneously, thus enabling the intermediate suspension assembly 33 and the mounting suspension assembly 31 to rotate in all directions.

[0058] In one embodiment of this application, see [reference] Figures 1 to 7 The mounting suspension assembly 31 also includes a mounting hinge rod 313, two mounting clamping arms 314, a mounting internal threaded pin 315, and a mounting external threaded pin 316. The mounting hinge rod 313 is connected to the mounting plate 311. The two mounting clamping arms 314 are each connected to the end of the mounting hinge rod 313 away from the mounting plate 311. The mounting internal threaded pin 315 passes through the two mounting clamping arms 314, and the mounting external threaded pin 316 is screwed into the mounting internal threaded pin 315.

[0059] With this configuration, the mounting strip 1 can be rotatably confined between the two mounting arms 314 under the action of the two mounting clamping arms 314. Under the action of the mounting internal threaded pin 315 and the mounting external threaded pin 316, they can act as pivots passing between the two mounting arms 314 and the mounting strip 1, facilitating the rotation of the mounting arms 314 relative to the mounting strip 1, and limiting the two mounting arms 314 to prevent them from detaching from the mounting strip 1.

[0060] In one embodiment of this application, please refer to Figures 1 to 7 The motherboard suspension assembly 32 also includes two motherboard clamping arms 323, a motherboard internal threaded pin 324, and a motherboard external threaded pin 325. The two motherboard clamping arms 323 are connected to the end of the motherboard hinge rod 321 near the computer motherboard 2. The motherboard internal threaded pin 324 passes through the two motherboard clamping arms 323, and the motherboard external threaded pin 325 is screwed into the motherboard internal threaded pin 324.

[0061] With this configuration, the mounting strip 1 can be rotatably confined between the two motherboard clamping arms 323 under the action of the two motherboard clamping arms 323. Under the action of the mounting internal threaded pin 315 and the mounting external threaded pin 316, they can act as pivots passing between the two motherboard clamping arms 323 and the mounting strip 1, facilitating the rotation of the motherboard clamping arms 323 relative to the mounting strip 1, and limiting the two motherboard clamping arms 323 to prevent them from detaching from the mounting strip 1.

[0062] The working principle of the computer with the ability to absorb physical impact provided in this application is as follows:

[0063] When the impact force on the sleeve 351 is less than a preset threshold, the deformation of the overload elastic structure 3533 is less than the depth of the slot 322. This means the impact force acting on the sleeve 351 is insufficient to disengage the locking lever 3531 from the slot 322, and the locking lever 3531 and the motherboard hinge lever 321 remain engaged. The impact force on the computer casing is applied to the sleeve 351 sequentially through the mounting strip 1, mounting suspension assembly 31, universal joint 34, intermediate suspension assembly 33, and shock-absorbing elastic structure 36. The shock-absorbing elastic structure 36 absorbs the impact force on the sleeve 351, thereby reducing the impact of vibration on the computer motherboard 2.

[0064] When the impact force on the sleeve 351 is greater than or equal to a preset threshold, the deformation of the overload elastic structure 3533 is greater than or equal to the depth of the slot 322. This means the impact force acting on the sleeve 351 is sufficient to disengage the latching lever 3531 from the slot 322, thus releasing the latching lever 3531 from the motherboard hinge lever 321. The impact force on the computer casing is applied to the sleeve 351 sequentially through the mounting strip 1, mounting suspension assembly 31, universal joint 34, intermediate suspension assembly 33, and shock-absorbing elastic structure 36. Because the latching lever 3531 and the motherboard hinge lever 321 are no longer locked, the impact force cannot be transmitted to the motherboard hinge lever 321, thus providing overload protection.

[0065] Example 2

[0066] This embodiment is basically the same as Embodiment 1, except that: Figures 1 to 8 As shown, the motherboard suspension assembly 32 includes a motherboard hinge rod 321 and a slot 322, with the slot 322 located at the end of the motherboard hinge rod 321 furthest from the computer motherboard 2. The overload protection assembly 35 includes a sleeve 351, a shearing rod 354, and two shearing slots 355. The sleeve 351 is fitted onto the motherboard hinge rod 321, and the shearing rod 354 passes through the motherboard hinge rod 321 and the sleeve 351. Both shearing slots 355 are located on the shearing rod 354. The gaps between the shearing slots 355 and the motherboard hinge rod 321 and sleeve 351 are correspondingly set.

[0067] With this configuration, when the impact force on the sleeve 351 is less than a preset threshold, the shearing force exerted by the sleeve 351 on the shear bar 354 is insufficient to cut the bar 354. The shear bar 354 allows the sleeve 351 and the motherboard hinge bar 321 to be stably engaged, and the shock-absorbing elastic structure 36 mitigates the impact force. When the impact force on the sleeve 351 exceeds the preset threshold, the sleeve 351 will move relative to the motherboard hinge bar 321, shearing the bar 354 through the two shearing slots 355, thus separating the sleeve 351 and the motherboard hinge bar 321. This prevents the impact force from acting on the computer motherboard 2 through the motherboard hinge bar 321, and also provides overload protection for the computer motherboard 2.

[0068] Example 3

[0069] This embodiment is basically the same as Embodiment 1, except that: Figures 1 to 9 As shown, the motherboard suspension assembly 32 includes a motherboard hinge rod 321 and a slot 322. The slot 322 is located at the end of the motherboard hinge rod 321 away from the computer motherboard 2. The overload protection assembly 35 includes multiple overload springs 356, multiple grooves 357, a sleeve 351, and a mounting plate 358. The multiple overload springs 356 are all installed at the end of the motherboard hinge rod 321 away from the computer motherboard 2, and each has a groove 357. The sleeve 351 is fitted around the outer periphery of the multiple overload springs 356, and the mounting plate 358 is connected to the inner periphery of the sleeve 351 and engages with the multiple grooves 357.

[0070] With this configuration, when the impact force on the sleeve 351 is less than a preset threshold, the card holder 358 is insufficient to disengage from the multiple grooves 357. Multiple overload springs 356 ensure a stable engagement between the sleeve 351 and the motherboard hinge rod 321, and the shock-absorbing elastic structure 36 mitigates the impact. When the impact force on the sleeve 351 exceeds the preset threshold, the sleeve 351 moves relative to the motherboard hinge rod 321. The card holder 358 causes the multiple overload springs 356 to converge, separating the sleeve 351 from the motherboard hinge rod 321. This prevents the impact force from acting on the computer motherboard 2 through the motherboard hinge rod 321, thus providing overload protection for the computer motherboard 2.

[0071] One or more embodiments in this application are intended to cover all such substitutions, modifications, and variations that fall within the broad scope of this application. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of one or more embodiments in this application should be included within the protection scope of this application.
