Description

Technical Field

[0001] The invention relates to the technical field of computer fastening, in particular to an embedded computer fastening structure. Background Art

[0002] In today's era of rapid technological development, embedded computers play a vital role in various fields. From industrial automation control to medical equipment, automotive electronics, aerospace and other fields, embedded computers have become an indispensable part of modern scientific and technological systems with their high efficiency, reliability and strong specialization.

[0003] As embedded computer application scenarios continue to expand and deepen, the requirements for their installation and fixation are also increasing. In many application environments, embedded computers often need to face complex working conditions, such as vibration and shock. These factors will not only affect the performance and stability of embedded computers, but may even cause damage to the equipment, thus affecting the normal operation of the entire system.

[0004] Traditional embedded computer installation methods are usually relatively simple, and may only be fixed by screws or placed directly in a specific location. However, this method is often not reliable enough when facing a harsh working environment. For example, in an industrial production site, the vibration of the machine may gradually loosen the embedded computer, thereby affecting the stability of its connection, and may even cause data transmission interruption or equipment failure. In the field of automotive electronics, the bumps and vibrations during vehicle driving will also challenge the tightness of embedded computers. If the embedded computer is not firmly installed inside the vehicle, it may affect its normal operation due to looseness, and even pose a potential threat to driving safety.

[0005] Although there are fastening structures for embedded computers in the disclosed technologies, for example, a Chinese patent with publication number CN115509308A discloses a fastening structure for an embedded industrial computer, which includes a base, and limit rods are longitudinally arranged at both ends inside the base, and the upper and lower ends of the two limit rods are fixedly connected to the inner wall of the base, and a movable plate is slidably arranged outside the two limit rods, and a computer body is arranged at the upper end of the movable plate, and a symmetrical first mounting block is fixedly arranged on the lower side wall of the computer body, and a symmetrical mounting opening is opened on the side wall of the movable plate, and two first mounting blocks are clamped with the mounting opening, and a strip plate is fixedly arranged on the lower side wall of the movable plate, and a cavity is opened inside the strip plate, and a screw rod is arranged inside the cavity for transverse rotation, so as to facilitate the rapid installation and fastening of the industrial computer. Although the fastening structure disclosed in the above patent is easy and convenient to operate, does not require any tools, and is not easy to loosen after fastening, it can be seen from the disclosed content that its size is large. For example, it wraps the computer body inside and is not suitable for embedded installation.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] The following is a further description with reference to the accompanying drawings and specific embodiments:

[0034] Example 1

[0035] In order to achieve vibration-proof installation of the embedded computer, adapt to the embedded installation space, and regularly store data cables, the present embodiment provides a new fastening structure for the embedded computer. The fastening mechanism can reduce the impact of vibration on the embedded computer, adapt to the Zener soft installation space, and regularly store data cables adjacent to the embedded computer.

[0036] Before introducing the fastening structure, a brief introduction is given to the existing publicly available embedded computer, for example, it includes a processor, a memory, an input / output interface, a power management module, etc. The processor can be set as a microcontroller (MCU), a digital signal processor (DSP), an application processor (AP), etc., the memory can be set as a random access memory (RAM), a read-only memory (ROM) and a flash memory (Flash), etc., the input / output interface can be set as a serial port, a parallel port, a USB interface, an Ethernet interface, a GPIO (general input / output), etc., and the power management module generally includes a power adapter, a battery management system, a power monitoring circuit, etc. The embedded computer designed in this embodiment is hereinafter referred to as a computer body 1, and a plurality of grooves are provided on the housing 11 of the computer body 1, and the length of the grooves is set along the length direction of the computer body 1.

[0037] like Figure 1 , Figure 2 As shown, specifically, the fastening structure includes four sets of mounting frames 2, which are respectively installed at four end corners above the shell 11 and can be fastened to the installation site by bolts. A shock-absorbing spring 4 can also be arranged above each set of mounting frames 2, and the top of the shock-absorbing spring 4 is connected to the installation site. Therefore, under the action of the shock-absorbing spring 4, the force exerted by vibration on the computer body 1 can be offset, thereby reducing the probability of damage to the computer body 1 due to vibration.

[0038] like Figure 7 As shown, in order to stably connect the mounting frame 2 to the shell 11, a first embedded plate 21 and a second embedded plate 22 are arranged below the mounting frame 2. The first embedded plate 21 and the second embedded plate 22 are both adapted to the groove of the shell 11, and the groove is arranged to have a narrower structure at the end. Therefore, when the lower ends of the first embedded plate 21 and the second embedded plate 22 are clamped in the groove of the shell 11, the mounting frame 2 is stably connected to the shell 11, and convenience is provided for disassembling the mounting frame 2 and the shell 11 as needed.

[0039] like Figure 8 , Fig. 9 As shown, in order to limit the relative position of the mounting frame 2 and the computer body 1, two oblique holes 14 are symmetrically arranged on the long side wall of the housing 11. The two oblique holes 14 are arranged adjacent to the mounting frame 2 and are located on the side where the two sets of mounting frames 2 are adjacent to each other. In addition, a baffle 13 is arranged through each oblique hole 14. The end portions of the two baffles 13 protruding from the housing 11 are arranged in contact with the two sets of mounting frames 2. Then, with the cooperation of the two baffles 13, the movement of the computer body 1 is limited, so that the computer body 1 is stably installed relative to the mounting frame 2, and it is convenient to disassemble the computer body 1 and the mounting frame 2 according to needs.

[0040] like Fig.10As shown, in order to control the movement of the two baffles 13 and adjust the position of the ends of the baffles 13 relative to the mounting frame 2, so as to facilitate the disassembly and assembly of the computer body 1, a rotating shaft 12 is arranged on the inner side of the housing 11, and the ends of the rotating shaft 12 are connected to the end wall of the computer body 1 through a bearing. Two groups of threaded structures 15 are symmetrically arranged on the rotating shaft 12, and each group of threaded structures 15 is threadedly sleeved with an internal threaded tube 16, and the two internal threaded tubes 16 are respectively hingedly connected to the two baffles 13 through the middle plate 17. Therefore, the two internal threaded tubes 16 can be controlled to move relative to each other (approach or move away from each other) by rotating the rotating shaft 12, and the movement of the baffle 13 can be controlled under the action of the middle plate 17, so that the position of the end angle of the baffle 13 can be changed.

[0041] like Figure 2 As shown, in order to be able to regularly store the data cables installed on the computer body 1, the fastening structure also includes two groups of limiting components 3, which are distributed at the front and rear ends of the embedded computer. The two groups of limiting components 3 are respectively opposite to the mounting frames 2 located at the front and rear ends of the computer body 1, that is, the two sets of mounting frames 2 located at the front end are opposite to the limiting components 3 located at the front end, and the two sets of mounting frames 2 located at the rear end are opposite to the limiting components 3 located at the rear end.

[0042] like Figure 3 , Figure 4 As shown, the limiting assembly 3 includes a horizontal plate 31, a pressing mechanism 32 and a fastening device 33. At least a second hole 314 is provided on the vertical side of the horizontal plate 31, and the second hole 314 is provided along the length direction of the horizontal plate 31. Therefore, when the data cable is installed on the computer body 1, the redundant data cable can be plugged into the second hole 314. In order to stably install the data cable in the second hole 314, a first hole 311 is provided on the top wall of the second hole 314. The first hole 311 and the second hole 314 have the same length. A threaded rod 312 is provided on the inner side of the second hole 314. The bottom of the threaded rod 312 is connected and inserted into the bottom plate of the second hole 314 through a bearing connection. The top surface of the threaded rod 312 is flush with the upper side surface of the horizontal plate 31 and is provided with a polygonal groove. Therefore, a polygonal wrench can be inserted into the polygonal groove to control the rotation of the threaded rod 312. The pressing mechanism 32 includes a main board 321, which is arranged at the first hole 311 and a threaded hole 322 that is threadedly penetrated by a threaded rod 312. Therefore, when the threaded rod 312 is rotated, the main board 321 can be controlled to descend and squeeze the data line so that the data line is stably placed on the horizontal plate 31.

[0043] like Figure 5As shown, in order to avoid damage to the data line, the pressing mechanism 32 also includes a pressing plate 324, which is arranged below the main board 321 and has a plurality of plug rods 325 on the upper side. A pressure spring 326 is sleeved on each plug rod 325, and the pressure spring 326 is in a compressed state, and the upper and lower ends are respectively connected to the lower pressing plate 324 and the main board 321, and the top of the plug rod 325 is inserted into the socket 323 of the main board 321. Therefore, the lower pressing plate 324 can be stably and movably arranged relative to the main board 321. Under the action of the pressure spring 326, when the main board 321 descends, the compression degree of the pressure spring 326 is changed. At the same time, the buffering effect of the pressure spring 326 is utilized to avoid damage to the data line due to excessive squeezing when the lower pressing plate 324 presses the data line.

[0044] like Figure 6 As shown, in order to stably install the cross plate 31 relative to the housing 11 and to enable the cross plate 31 to be disassembled as required, a mounting groove 315 is provided below the cross plate 31, and the fastening device 33 is arranged in the mounting groove 315 and extends into the groove of the housing 11. The fastening device 33 includes a threaded column 316, a movable block 331 and a frustum column 333. The threaded column 316 is threaded through the frustum column 333. The movable blocks 331 are symmetrically arranged and are respectively arranged on both sides of the frustum column 333. The end of the frustum column 333 with a smaller diameter extends between the two movable blocks 331. Therefore, when the threaded column 316 is rotated, the frustum column 333 can be forced to move and penetrate into the inner side of the two movable blocks 331. By utilizing the characteristics of the frustum column 333, the two movable blocks 331 are forced to move away from each other and press against the side wall of the groove, so that the cross plate 31 is stably installed relative to the housing 11. In addition, when the transverse plate 31 needs to be disassembled, the threaded column 316 is rotated in the opposite direction to release the restriction of the movable block 331, so that the fastening device 33 can be pulled out of the groove, thereby facilitating the separation of the transverse plate 31 from the housing 11.

[0045] like Figure 6 As shown, in order to make the movable block 331 movable and stably arranged in the installation groove 315, a clamping plate 317 is arranged on the side wall of the installation groove 315, and a convex column 318 is fixedly arranged on the top wall. A clamping groove 332 is arranged on the end face of the movable block 331, and the clamping plate 317 is installed at the clamping groove 332. Therefore, the movable block 331 is stably installed relative to the horizontal plate 31. A groove 335 is arranged on the frustum column 333, and the convex column 318 is located at the groove 335, which limits the rotation of the frustum column 333 and prevents it from rotating with the threaded column 316. The end of the threaded column 316 is connected to the end wall of the installation groove 315 through a bearing, and a polygonal groove is arranged on the end face.

[0046] Example 2

[0047] like Figure 4 , Figure 7As shown, in addition, in order to make the horizontal plate 31 detachably connected to the mounting frame 2, a snap groove 313 is provided on the end face of the horizontal plate 31, and one end of the snap groove 313 is set to be open. A snap plate 23 is fixedly provided on the end faces of the two mounting frames 2 at the same end of the computer body 1 that are close to each other. The snap plate 23 is located in the snap groove 313, thereby realizing the connection between the horizontal plate 31 and the mounting frame 2, and providing convenience for disassembling the horizontal plate 31 and the mounting frame 2.

[0048] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
