[0048] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0049] Before the invention is described in detail, it should be noted that similar elements are represented by the same numbers in the following description.

[0050] See Figure 1 and Figure 2 The first embodiment of the electronic device 100 of the present invention includes an electronic device 1, a bracket 2, a plurality of locking accessories 3, and a shock-absorbing device 4.

[0051] For ease of subsequent explanation, we define the electronic device 100 as having a front-back direction X, a left-right direction Y perpendicular to the front-back direction X, and a vertical direction Z perpendicular to both the front-back direction X and the left-right direction Y. Figure 1The forward and backward direction X refers to the direction indicated by the arrow as forward and the opposite direction as backward. Figure 1 The left and right directions Y are defined as the direction the arrow points to (left) and the opposite direction (right). Figure 1 The up and down direction Z refers to the direction indicated by the arrow as up, and the opposite direction as down.

[0052] The electronic device 100 is exemplified by its application in an in-vehicle system. The electronic device 1 is exemplified by a touchscreen display, but is not limited thereto. The electronic device 1 can also be a non-touchscreen display, a tablet computer, or a Global Positioning System (GPS). The electronic device 1 has a rear-facing back surface 11. The back surface 11 has a plurality of spaced-apart locking portions 111. The bracket 2 is used for mounting to a vehicle structure (not shown). The bracket 2 includes a vertical frame 21. The vertical frame 21 has a plurality of spaced-apart through holes 211. The shock-absorbing device 4 is disposed between the back surface 11 of the electronic device 1 and the vertical frame 21 of the bracket 2 and is fixedly attached to the back surface 11. The locking attachments 3 pass through the through holes 211 and are screwed onto the shock-absorbing device 4 to lock the bracket 2 to the shock-absorbing device 4.

[0053] See Figure 2 , Figure 3 , Figure 4 and Figure 5 The shock-absorbing device 4 includes a shock-absorbing mechanism 5 and a plurality of locking fasteners 6. The shock-absorbing mechanism 5 includes a front shell 51, a rear shell 53, and an elastic pad 55. The front shell 51 and the rear shell 53 each cover a portion of the elastic pad 55, and the elastic pad 55 separates the front shell 51 and the rear shell 53 so that the front shell 51 and the rear shell 53 are spaced apart and do not contact each other.

[0054] The front shell 51 and the rear shell 53 are each made of a metal material, such as aluminum alloy, but not limited thereto. The front shell 51 has a front plate 510, a plurality of positioning protrusions 511, and a front surrounding wall 512. The front plate 510 has a front surface 513 and a rear surface 514 opposite to the front surface 513. The front surface 513 is used to abut against the back surface 11 of the electronic device 1. The front plate 510 has a plurality of through holes 515 extending between the front surface 513 and the rear surface 514 and spaced apart from each other. The through holes 515 are respectively used for the fasteners 6 to pass through. Each fastener 6 is used to abut against the rear surface 514 of the front plate 510 and partially protrudes from the corresponding through hole 515 to be screwed into the corresponding locking part 111. In this way, the fasteners 6 can lock the front shell 51 to the back surface 11 of the electronic device 1. In this first embodiment, each locking part 111 is a screw hole, and each locking member 6 is a screw for screwing into the corresponding locking part 111. The spatial configuration and positional distribution of the locking parts 111 and the through holes 515 conform to VESA specifications. The positioning protrusions 511 protrude from the rear surface 514 of the front plate 510 and are spaced apart from each other. The front surrounding wall 512 extends rearward from the outer periphery of the front plate 510. The front plate 510 and the front surrounding wall 512 of the front shell 51 are used to cover the portion of the elastic pad 55 near the front end.

[0055] The front shell 51 has a plurality of through holes 516 spaced apart from each other. In this first embodiment, the front plate 510 and each of the positioning protrusions 511 jointly define the corresponding through hole 516. Each through hole 516 has a small diameter portion 517 and a large diameter portion 518. The small diameter portion 517 is defined by the positioning protrusion 511 and is located away from the front plate 510. The large diameter portion 518 communicates with the front end of the small diameter portion 517 and is jointly defined by the front plate 510 and the positioning protrusion 511. The diameter of the large diameter portion 518 is larger than the diameter of the small diameter portion 517. A stop shoulder surface 519 is formed between the small diameter portion 517 and the large diameter portion 518.

[0056] The rear shell 53 is located behind the front shell 51 along the front-rear direction X. The rear shell 53 has a rear plate 530, a plurality of positioning protrusions 531, a plurality of abutting protrusions 532, a top abutment block 533, and a rear surrounding wall 534. The rear plate 530 has a front surface 535 and a rear surface 536 opposite to the front surface 535. The positioning protrusions 531 protrude from the front surface 535 and are spaced apart from each other. The abutting protrusions 532 protrude from the rear surface 536 and are respectively positioned opposite to the positioning protrusions 531. The abutting protrusions 532 are used to abut against the frame 21 of the bracket 2. The top abutment block 533 protrudes from the front surface 535 and is surrounded by the positioning protrusions 531. The rear surrounding wall 534 extends forward from the outer periphery of the rear plate 530. The rear plate 530 of the rear shell 53 and the rear surrounding wall 534 are used to cover the elastic pad 55 near the rear end.

[0057] The rear housing 53 has a plurality of locking portions 537 spaced apart from each other, each locking portion 537 being used for screwing the locking attachment 3. In this first embodiment, each locking portion 537 is a screw hole formed in the rear plate 530, corresponding to the positioning protrusion 531 and the abutment protrusion 532. Each locking attachment 3 is a screw for screwing into the corresponding locking portion 537. The spatial configuration and positional distribution of the through hole 211 and the locking portions 537 conform to VESA specifications.

[0058] The rear shell 53 also has an opening 538 located between the locking portions 537. In this first embodiment, the rear plate 530 and the abutment block 533 jointly define the opening 538. The opening 538 has a small-diameter portion 539 and a large-diameter portion 540. The small-diameter portion 539 is defined by the abutment block 533 and is located away from the rear plate 530. The large-diameter portion 540 communicates with the rear end of the small-diameter portion 539 and is jointly defined by the rear plate 530 and the abutment block 533. The diameter of the large-diameter portion 540 is larger than the diameter of the small-diameter portion 539. The rear shell 53 also has a stop shoulder surface 541 located between the small-diameter portion 539 and the large-diameter portion 540.

[0059] See Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7The elastic pad 55 is disposed between the front shell 51 and the rear shell 53. The elastic pad 55 is made of rubber or silicone. The elastic pad 55 has a pad body 550 and a plurality of pillars 551. The pad body 550 is, for example, square plate-shaped. The pillars 551 are formed at the four corners of the pad body 550 and protrude from the rear end of the pad body 550. The pillars 551 are spaced apart from each other.

[0060] The shock-absorbing mechanism 5 also includes multiple nuts 57, a connector 58, multiple locking screws 59, and a nut 60. Each of the nuts 57, connectors 58, locking screws 59, and nut 60 is made of metal. The elastic pad 55's pad body 550 is integrally formed to partially cover the nuts 57 and partially cover the connectors 58, so that the elastic pad 55, nuts 57, and connectors 58 together constitute a single component S. The nuts 57 are spaced apart from each other on the pad body 550. The elastic pad 55's pad body 550 has multiple spaced-apart positioning grooves 552. The positioning grooves 552 are respectively used for engaging the positioning protrusions 511. In this first embodiment, the positioning grooves 552 correspond to the positions of the nuts 57 respectively. The front end of each nut 57 is not covered by the pad 550 and can be exposed through the corresponding positioning groove 552, so that each nut 57 can correspond to the position of the through hole 516 of the corresponding positioning protrusion 511 that is engaged in the corresponding positioning groove 552.

[0061] The connector 58 has a support plate 581 and a stud 582 protruding from the rear end of the support plate 581. The elastic pad 55 has a pad body 550 integrally formed to cover a portion of the support plate 581 and the stud 582, leaving another portion of the stud 582 exposed. The portion of the stud 582 exposed above the pad body 550 is used to pass through the opening 538 of the rear housing 53. Specifically, the support plate 581 has a circular plate 583 connected to the stud 582, a first annular plate 584 extending radially outward and forward inclined from the outer periphery of the circular plate 583, and a second annular plate 585 extending radially outward from the outer periphery of the first annular plate 584.

[0062] Each locking screw 59 is inserted into the corresponding through hole 516 of the front housing 51 and screwed into the corresponding nut 57 to secure the front housing 51 to the elastic pad 55. Each locking screw 59 has a small-diameter portion 517 inserted into the corresponding through hole 516 and screwed into the corresponding nut 57, and a screw head 592 accommodated in the large-diameter portion 518 of the corresponding through hole 516 and abutting against the stop shoulder surface 519. The nut 60 is accommodated in the large-diameter portion 540 of the opening 538 and screwed into the stud 582 of the connector 58 and abutting against the stop shoulder surface 541 to secure the rear housing 53 to the elastic pad 55.

[0063] See Figure 4 , Figure 5 and Figure 6 Each of the pillars 551 of the elastic pad 55 has a positioning hole 553. The positioning hole 553 is used to engage with the corresponding positioning protrusion 531 of the rear shell 53. In this first embodiment, the spatial configuration and positional distribution of the positioning holes 553 of the elastic pad 55 conform to VESA specifications. The positioning holes 553 are respectively used to communicate with the through holes 515 of the front shell 51 and can be respectively used for the fasteners 6 to pass through. Each positioning hole 553 is used to guide the corresponding fastener 6 to pass through the corresponding through hole 515. Specifically, each positioning hole 553 has a small diameter portion 554 and a large diameter portion 555. The small diameter portion 554 is adjacent to the front end of the pillar 551 and is used to accommodate a portion of the corresponding fastener 6. The large diameter portion 555 communicates with the rear end of the small diameter portion 554 and is adjacent to the rear end of the pillar 551 and is used to engage with the corresponding positioning protrusion 531. A stop shoulder 556 is formed between the small aperture portion 554 and the large aperture portion 555 to stop the corresponding positioning protrusion 531 and limit its insertion depth into the large aperture portion 555.

[0064] See Figure 2 , Figure 4 , Figure 5 and Figure 8To assemble the shock-absorbing device 4 between the electronic device 1 and the bracket 2, the assembly between the front shell 51 and the elastic pad 55 is performed first. First, the rear surface 514 of the front shell 51 faces the elastic pad 55, and the positioning protrusions 511 are aligned with the positioning grooves 552 of the elastic pad 55. Then, the front shell 51 is moved towards the elastic pad 55, so that the rear surface 514 abuts against the elastic pad 55 and the positioning protrusions 511 are engaged with the positioning grooves 552. Subsequently, each locking screw 59 is inserted into the corresponding through hole 516, so that the stud 591 is screwed into the corresponding nut 57 through the small diameter portion 517. When the screw head 592 of each locking screw 59 is received in the large-diameter portion 518 and abuts against the stop shoulder surface 519, the torque applied to the front housing 51 by the locking screw 59 causes the front housing 51 to abut against the elastic pad 55. In this way, the locking screw 59 can press and lock the front housing 51 against the elastic pad 55.

[0065] By engaging the positioning protrusions 511 with the positioning grooves 552, the stability of the connection between the front shell 51 and the elastic pad 55 is increased. This prevents the elastic pad 55 from wobbling relative to the front shell 51 in the two-dimensional plane formed by the front-rear direction X and the left-right direction Y, and enhances the structural strength of the elastic pad 55 in supporting the front shell 51 in the vertical direction Z. By defining the corresponding through hole 516 together with each positioning protrusion 511, the positioning protrusion 511 engaging with the corresponding positioning groove 552 allows the through hole 516 to be positioned aligned with the corresponding nut 57, thereby improving the ease of operation for each locking screw 59 to be screwed into the corresponding nut 57 through the corresponding through hole 516. Furthermore, after each locking screw 59 is secured, the screw head 592 will be accommodated within the large-diameter portion 518 without protruding from the front surface 513 of the front plate 510, so that the front shell 51 can abut against the back surface 11 of the electronic device 1 through the front surface 513.

[0066] See Figure 2 and Figure 9Next, the front shell 51 is assembled with the electronic device 1. First, the front surface 513 of the front shell 51 faces the back surface 11 of the electronic device 1, and the through holes 515 are aligned with the locking portions 111. Then, the front shell 51 is moved toward the electronic device 1, so that the front surface 513 abuts against the back surface 11 and the through holes 515 connect to the locking portions 111. Subsequently, each locking fastener 6 is inserted into the corresponding positioning hole 553 of the elastic pad 55 and the corresponding through hole 515 of the front shell 51, and screwed into the corresponding locking portion 111 of the electronic device 1. When a portion of each locking fastener 6 is accommodated in the small diameter portion 554 of the corresponding positioning hole 553 and abuts against the rear surface 514, the locking fastener 6 can press and lock the front shell 51 onto the electronic device 1. By securing the front housing 51 to the electronic device 1 using the fastener 6, the rotational torque of the fastener 6 can be controlled, and the shock-absorbing device 4 can be rigidly connected to the electronic device 1 through a rigid structure formed by the front housing 51 and the fastener 6. This effectively improves the stability of the connection between the shock-absorbing device 4 and the electronic device 1.

[0067] See Figure 2 , Figure 10 and Figure 11 Next, the rear shell 53 and the elastic pad 55 are assembled. First, the front surface 535 of the rear shell 53 faces the elastic pad 55, the opening 538 of the rear shell 53 is aligned with the stud 582 of the connector 58, and the positioning protrusion 531 is aligned with the large diameter portion 555 of the positioning hole 553. Then, the rear shell 53 is moved toward the elastic pad 55, so that the abutment block 533 of the rear shell 53 abuts against the pad body 550 of the elastic pad 55, the stud 582 passes through the opening 538, and the positioning protrusion 531 is engaged with the large diameter portion 555 of the positioning hole 553. Finally, the nut 60 is screwed onto the stud 582. When the nut 60 is received in the large-diameter portion 540 of the opening 538 and abuts against the stop shoulder surface 541, the torque applied by the nut 60 to the rear housing 53 causes the abutting block 533 to abut against the pad body 550 of the elastic pad 55, and each of the positioning protrusions 531 to abut against the corresponding stop shoulder surface 556. In this way, the nut 60 can press and lock the rear housing 53 against the elastic pad 55.

[0068] By engaging the positioning protrusions 531 with the large-diameter portions 555 of the positioning holes 553, the stability of the connection between the rear shell 53 and the elastic pad 55 is increased. This prevents the elastic pad 55 from wobbling relative to the rear shell 53 in the two-dimensional plane formed by the front-rear direction X and the left-right direction Y, and enhances the structural strength of the rear shell 53 supporting the elastic pad 55 in the vertical direction Z. By blocking the corresponding positioning protrusion 531 with each stop shoulder 556, the depth of each positioning protrusion 531 inserted into the large-diameter portion 555 of the corresponding positioning hole 553 is limited, thereby preventing each positioning protrusion 531 from contacting the corresponding locking fastener 6. The shape design of the opening 538 allows most of the volume of the nut 60 to be accommodated within the large-diameter portion 540 after locking, reducing the volume of the nut 60 protruding from the rear surface 536 of the rear plate 530. Furthermore, the shape design of the support plate 581 can enhance the structural strength of the elastic pad 550 in the front-rear direction X, and can prevent the pad 550 from deforming too much due to the force of the top block 533 pressing against the pad 550, thereby causing the rear surrounding wall 534 of the rear shell 53 to contact the front surrounding wall 512 of the front shell 51.

[0069] See Figure 2 and Figure 11 Finally, the rear shell 53 and the bracket 2 are assembled. First, the rear surface 536 of the rear shell 53 faces the upright body 21 of the bracket 2, and the locking part 537 is aligned with the through hole 211. Then, the rear shell 53 is moved toward the upright body 21, so that the abutting protrusion 532 of the rear shell 53 abuts against the upright body 21, and the locking part 537 is connected to the through hole 211. Subsequently, each locking attachment 3 is inserted into the corresponding through hole 211 and screwed into the corresponding locking part 537. When each locking attachment 3 abuts against the rear end of the upright body 21, the locking attachment 3 can press and lock the bracket 2 onto the rear shell 53, thus completing the assembly of the shock absorption device 4. By locking the bracket 2 to the rear shell 53 using the locking attachment 3, the rotational locking torque of the locking attachment 3 can be controlled, and the shock-absorbing device 4 can be rigidly connected to the bracket 2 through a rigid structure formed by the rear shell 53 and the locking attachment 3. This effectively improves the stability of the connection between the shock-absorbing device 4 and the bracket 2.

[0070] See Figure 1 , Figure 10 and Figure 11The bracket 2 is installed on the vehicle structure, enabling the electronic device 100 to function as a display device for the in-vehicle system. The elastic pad 55 of the shock-absorbing device 4 is positioned between the front shell 51 and the rear shell 53, separating them and preventing the two rigid components, the front shell 51 and the rear shell 53, from connecting or contacting each other. By having each of the front shell 51 and the rear shell 53 partially cover the elastic pad 55, the contact area between the front shell 51 and the rear shell 53 and the elastic pad 55 is maximized. When vibrations generated by the vehicle structure are transmitted to the elastic pad 55 through the bracket 2 and the rear shell 53, the elastic pad 55 absorbs the vibrations through its own deformation, providing cushioning and shock absorption, thereby significantly reducing the impact of vibrations on the front shell 51, the fastener 6, and the electronic device 1. This ensures that the locking fastener 6 securely locks the front shell 51 to the electronic device 1 and prevents the electronic device 1 from becoming loose. On the other hand, when the electronic device 1 vibrates due to touch or impact from external objects, the vibration is transmitted through the front shell 51 to the elastic pad 55. The elastic pad 55 absorbs the vibration through its own deformation, providing cushioning and shock absorption, thereby significantly reducing the impact of the vibration on the rear shell 53, the locking accessory 3, and the bracket 2. This ensures that the locking accessory 3 securely locks the rear shell 53 to the bracket 2 and prevents the shock-absorbing device 4 from becoming loose.

[0071] By including the locking fastener 6 in the shock-absorbing device 4, the shock-absorbing mechanism 5 can be locked to the electronic device 1 via the locking fastener 6. The locking part 537 formed on the rear shell 53 allows the shock-absorbing mechanism 5 to be locked to the bracket 2 via the locking attachment 3. This improves the ease of assembling the shock-absorbing device 4 between the electronic device 1 and the bracket 2. In other embodiments of this first embodiment, the front shell 51 and the electronic device 1, or the rear shell 53 and the bracket 2, can also be fixedly connected together by, for example, a snap-fit ​​method involving a hook and slot, or other suitable connection and fixing methods.

[0072] See Figure 12 The second embodiment of the electronic device 100 of the present invention has a generally similar overall structure to the first embodiment, except for the shock absorption device 4.

[0073] See Figure 12 , Figure 13 and Figure 14The rear shell 53 includes a shell member 542 and a plurality of locking pins 543. The elastic pad 55 is integrally formed with the front shell 51 and the shell member 542, such that the elastic pad 55, the front shell 51, and the shell member 542 together constitute a single component S. The front shell 51 has a front plate 510 and a front surrounding wall 512. The front plate 510 of the front shell 51 forms a front locking hole 520. The shell member 542 of the rear shell 53 has a rear plate 530 and a rear surrounding wall 534. The rear plate 530 of the shell member 542 forms a rear locking hole 544. The pad body 550 of the elastic pad 55 has a body portion 557. The front plate 510 and the rear plate 530 clamp the body portion 557, and the front surrounding wall 512 and the rear surrounding wall 534 surround and fix the body portion 557. The elastic pad 55 also has a front latching member 558 and a rear latching member 559. The front latching member 558 protrudes from the front end of the body portion 557 of the pad body 550 and latches into the front latching hole 520. The rear latching member 559 protrudes from the rear end of the body portion 557 of the pad body 550 and latches into the rear latching hole 544. By clamping the body portion 557 with the front plate 510 and the rear plate 530, the front latching member 558 latching into the front latching hole 520, and the rear latching member 559 latching into the rear latching hole 544, the elastic pad 55 can be prevented from swaying relative to the front shell 51 and the shell 542 in the front-rear direction X. By surrounding and securing the main body portion 557 with the front surrounding wall 512 and the rear surrounding wall 534, the elastic pad 55 can be prevented from wobbling relative to the front shell 51 and the shell member 542 in the two-dimensional plane jointly formed by the front-rear direction X and the left-right direction Y. This allows the elastic pad 55 to be securely attached between the front shell 51 and the shell member 542.

[0074] The front locking hole 520 has a small-diameter front opening 521 adjacent to the body portion 557 of the pad 550, and a large-diameter front opening 522 communicating with the front end of the small-diameter front opening 521. The diameter of the large-diameter front opening 522 is larger than the diameter of the small-diameter front opening 521. The front locking member 558 has a front connecting post 560 connected to the body portion 557 of the pad 550 and passing through and engaging with the small-diameter front opening 521, and a front locking post 561 formed at the front end of the front connecting post 560 and engaging with the large-diameter front opening 522. By engaging the small-diameter front opening 521 with the front connecting post 560, the elastic pad 55 can be prevented from wobbling relative to the front shell 51 in the two-dimensional plane jointly formed by the front-rear direction X and the left-right direction Y. By engaging the front snap-fit ​​post 561 with the front large-diameter portion 522, the elastic pad 55 is prevented from moving rearward relative to the front shell 51 along the front-rear direction X. The rear snap-fit ​​hole 544 has a rear small-diameter portion 545 adjacent to the body portion 557 of the pad body 550, and a rear large-diameter portion 546 communicating with the rear end of the rear small-diameter portion 545. The diameter of the rear large-diameter portion 546 is larger than the diameter of the rear small-diameter portion 545. The rear snap-fit ​​member 559 has a rear connecting post 562 connected to the body portion 557 of the pad body 550 and passing through and engaging with the rear small-diameter portion 545, and a rear snap-fit ​​post 563 formed at the rear end of the rear connecting post 562 and engaging with the rear large-diameter portion 546. By engaging the rear connecting post 562 with the rear small-diameter portion 545, the elastic pad 55 can be prevented from wobbling relative to the housing 542 in the two-dimensional plane formed by the front-rear direction X and the left-right direction Y. By engaging the rear locking post 563 with the rear large-diameter portion 546, the elastic pad 55 can be prevented from moving forward relative to the housing 542 along the front-rear direction X.

[0075] The front panel 510 has a front upright plate 523 and a front recessed plate 524 recessed rearward from the front upright plate 523. The front recessed plate 524 forms the front locking hole 520. The main body portion 557 and the front fastener 558 together cover the front recessed plate 524, thereby further increasing the stability of the connection between the elastic pad 55 and the front panel 510. In addition, by forming the front locking hole 520 in the front recessed plate 524, the front locking post 561 can be flush with the front upright plate 523 when it is engaged with the front large diameter portion 522 without protruding from the front upright plate 523.

[0076] The rear plate 530 has a rear upright plate 547 and a rear recessed plate 548 recessed forward from the rear upright plate 547. The rear recessed plate 548 forms the rear locking hole 544. The main body portion 557 and the rear locking member 559 together cover the rear recessed plate 548, thereby further increasing the stability of the connection between the elastic pad 55 and the rear plate 530. In addition, by forming the rear locking hole 544 in the rear recessed plate 548, the rear locking post 563 can be flush with the rear upright plate 547 when it is locked in the rear large diameter portion 546 without protruding from the rear upright plate 547.

[0077] The elastic pad 55's pad body 550 also has an annular rib 564. The annular rib 564 protrudes from the outer periphery of the body portion 557. The front surrounding wall 512 of the front shell 51 and the rear surrounding wall 534 of the shell member 542 are spaced apart and clamp the annular rib 564. The annular rib 564 serves to separate the front surrounding wall 512 and the rear surrounding wall 534 to prevent the front shell 51 from contacting the shell member 542.

[0078] See Figure 12 , Figure 13 , Figure 15 and Figure 16 The elastic pad 55 has a positioning hole 553 formed in the body portion 557 of the pad body 550. The housing 542 has positioning protrusions 531 that protrude from the front surface 535 of the rear plate 530 and are spaced apart from each other. The positioning protrusions 531 are respectively positioned in the large diameter portion 555 of the positioning hole 553. Each positioning protrusion 531 has a mounting hole 549. Each locking pin 543 is detachably mounted in the mounting hole 549 of the corresponding positioning protrusion 531.

[0079] Specifically, the mounting hole 549 has a small-diameter portion 565 communicating with the corresponding positioning hole 553, and a large-diameter portion 566 communicating with the rear end of the small-diameter portion 565. The diameter of the large-diameter portion 566 is larger than the diameter of the small-diameter portion 565. The large-diameter portion 566 is a threaded hole. The mounting hole 549 is used to guide the corresponding locking fastener 6 to pass through the corresponding positioning hole 553. Each positioning protrusion 531 has a stop shoulder surface 567 between the small-diameter portion 565 and the large-diameter portion 566. Each locking post 543 has a stud body 568 and a corner post 569. The stud body 568 is used to screw into the large-diameter portion 566 and to abut against the stop shoulder surface 567. The angular prism 569 protrudes from the rear end of the stud 568, serving to hold a sleeve (not shown) and to be rotated by the sleeve. The angular prism 569 is exemplified by a hexagonal prism, but is not limited thereto. Each locking portion 537 is a threaded hole formed in the corresponding stud 568 and angular prism 569 of the locking post 543.

[0080] See Figure 12 , Figure 13 and Figure 16 When assembling the shock-absorbing device 4 between the electronic device 1 and the bracket 2, the assembly of the single component S with the electronic device 1 is performed first. First, the front surface 513 of the front shell 51 faces the back surface 11 of the electronic device 1, and the through holes 515 are aligned with the locking portions 111. Then, the front shell 51 is moved toward the electronic device 1, so that the front surface 513 abuts against the back surface 11 and the through holes 515 connect to the locking portions 111. Subsequently, each locking fastener 6 passes through the corresponding mounting hole 549 of the shell 542 and through the corresponding positioning hole 553 of the elastic pad 55, and is screwed into the corresponding locking portion 111 of the electronic device 1, so that the locking fastener 6 presses and locks the front shell 51 to the electronic device 1.

[0081] Next, the stud 568 of each locking pin 543 is screwed into the large-diameter portion 566 of the corresponding mounting hole 549 of the housing 542. The sleeve holds the corner post 569 of the corresponding locking pin 543 and rotates it, allowing the stud 568 to screw into the large-diameter portion 566. When the stud 568 of each locking pin 543 abuts against the stop shoulder 567, the stud 568 is housed within the corresponding mounting hole 549, while the corner post 569 protrudes from the large-diameter portion 566 of the corresponding mounting hole 549.

[0082] Next, the rear surface 536 of the housing 542 is aligned with the upright body 21 of the bracket 2, and the locking part 537 is aligned with the through hole 211. Then, the rear housing 53 is moved toward the upright body 21, so that the corner post 569 of the locking post 543 abuts against the upright body 21, and the locking part 537 is connected to the through hole 211. Subsequently, each locking attachment 3 is inserted into the corresponding through hole 211 and screwed into the corresponding locking part 537. When each locking attachment 3 abuts against the rear end of the upright body 21, the locking attachment 3 can press and lock the bracket 2 to the rear housing 53, thus completing the assembly of the shock absorption device 4.

[0083] The shock-absorbing device 4 of this second embodiment has a simple structure and few components. Therefore, it can effectively improve the speed and efficiency of assembling the shock-absorbing device 4 between the electronic device 1 and the bracket 2, and save assembly time.

[0084] In summary, the electronic device 100 of each embodiment, by having the front shell 51 and the rear shell 53 respectively attached to the electronic device 1 and the bracket 2, and the elastic pad 55 disposed between the front shell 51 and the rear shell 53 and separating them, ensures that the front shell 51 and the rear shell 53 do not contact each other, and that the vibrations received by each shell are directly transmitted to the elastic pad 55. By having the front shell 51 and the rear shell 53 each cover a portion of the elastic pad 55, the contact area between the front shell 51 and the rear shell 53 and the elastic pad 55 is large. Therefore, when the elastic pad 55 receives vibration, it can absorb the vibration through its own deformation, thus achieving a buffering and shock-absorbing effect. This allows the electronic device 100 to meet the usage requirements of harsh vibration environments such as vehicle systems or heavy machinery, effectively achieving the objectives claimed by this invention.
