[0002] A display screen structure such as disclosed in Chinese patent document CN117698584A, in order to facilitate hand touch and eye view, the display screen is usually extended out of the instrument mounting bracket. However, when the display screen is mounted on an engineering vehicle such as a truck or a truck, since the driving environment of the engineering vehicle is usually in a remote suburb, the road surface of the suburb is usually uneven under the rolling of the engineering vehicle loaded with tonnage construction equipment, and the engineering vehicle driving on the uneven road surface will vibrate and shake. At this time, the display screen is effectively supported due to the extension out of the instrument mounting bracket, so that the display screen is easy to shake during driving, causing the control circuit board assembly of the display screen to vibrate, and further causing unstable connection of the circuit on the control circuit board assembly.

The terminology used in the description of the disclosure herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0034] In order to better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure will be further described in detail below in conjunction with specific embodiments:

[0035] Please refer to Figure 1 With Figure 2The display screen mounting structure of the construction vehicle in an embodiment comprises a meter mounting rack 100, a display screen main body 200, an inner heat-conducting rigid rack 300 and an outer heat-conducting rigid rack 400; the meter mounting rack 100 is used to be mounted on the construction vehicle, and the outer surface of the meter mounting rack 100 is provided with a mounting position 101; the display screen main body 200 is arranged at the mounting position 101 and keeps an inclination with the outer surface of the meter mounting rack 100; the inner heat-conducting rigid rack 300 is used to be fixedly mounted in the interior of the vehicle body of the construction vehicle; a part of the inner heat-conducting rigid rack 300 is attached and mounted on the inner surface of the meter mounting rack 100 and corresponds to the position of the mounting position 101; the outer heat-conducting rigid rack 400 is arranged between the display screen main body 200 and the meter mounting rack 100; a first part of the outer heat-conducting rigid rack 400 is located on the mounting position 101 and is fixedly connected to the meter mounting rack 100; a second part of the outer heat-conducting rigid rack 400 is embedded in the interior of the display screen main body 200 and is fixedly attached to the control circuit board assembly 210 of the display screen main body 200.

[0036] It can be understood that, since the inner heat-conducting rigid rack 300 is fixedly mounted in the interior of the vehicle body of the construction vehicle and a part of the inner heat-conducting rigid rack 300 is attached and mounted on the inner surface of the meter mounting rack 100, the entire meter mounting rack 100 can be stably supported by the inner heat-conducting rigid rack 300, so that the entire meter mounting rack 100 can keep a synchronous movement with the vehicle body of the construction vehicle. Since the first part of the outer heat-conducting rigid rack 400 is fixedly connected to the meter mounting rack 100 on the mounting position 101 and the second part of the outer heat-conducting rigid rack 400 is embedded in the interior of the display screen main body 200 and is fixedly attached to the control circuit board assembly 210 of the display screen main body 200, the connection strength between the control circuit board assembly 210 and the meter mounting rack 100 can be enhanced by the outer heat-conducting rigid rack 400, the shaking amount of the control circuit board assembly 210 relative to the vehicle body of the construction vehicle can be reduced, and the line connection on the control circuit board assembly 210 can be more stable. Meanwhile, after the outer heat-conducting rigid rack 400 is attached to the control circuit board assembly 210, the heat generated by the control circuit board assembly 210 during operation can be conducted to the inner heat-conducting rigid rack 300, and the heat dissipation efficiency of the control circuit board assembly 210 can be further improved.

[0037] Please refer to Figure 2 and Figure 3In some embodiments, the outer heat-conducting rigid frame 400 comprises a one-piece shell-attached portion 410 and a supporting leg 420; the supporting leg 420 is obliquely arranged on the mounting site 101 and fixedly connected with the instrument mounting frame 100; the shell-attached portion 410 is located inside the display screen main body 200, and the control circuit board assembly 210 of the display screen main body 200 is fixedly attached to the shell-attached portion 410. It can be understood that, since the control circuit board assembly 210 of the display screen main body 200 is fixedly attached to the shell-attached portion 410, the control circuit board assembly 210 of the display screen main body 200 can be fixedly carried by the shell-attached portion 410, and then the control circuit board assembly 210 of the display screen main body 200 can be stably fixed on the instrument mounting frame 100 by the supporting leg 420 fixedly connected with the instrument mounting frame 100, thereby further reducing the displacement of the control circuit board assembly 210 under the action of inertia relative to the engineering vehicle.

[0038] Referring to Figure 2 and Figure 3 In some embodiments, the number of the supporting legs 420 is two, and the two supporting legs 420 are dispersedly arranged at two ends of the shell-attached portion 410. It can be understood that, by arranging two supporting legs 420, the center of gravity of the shell-attached portion 410 can be well balanced after the two supporting legs 420 are dispersedly arranged at the two ends of the shell-attached portion 410, so that the position of the shell-attached portion 410 is more stable.

[0039] Referring to Figure 1 and Figure 2 In some embodiments, the instrument mounting frame 100 is provided with a through hole 1011 at the mounting site 101, the supporting leg 420 is provided with a first hole 4201, and the inner heat-conducting rigid frame 300 is provided with a second hole 301; a bolt (not shown) on the supporting leg 420 is sequentially threaded through the first hole 4201, the through hole 1011 and the second hole 301, and is locked and connected to a nut (not shown) on the inner heat-conducting rigid frame 300. It can be understood that, since the instrument mounting frame 100 is provided with the through hole 1011 at the mounting site 101, the supporting leg 420 is provided with the first hole 4201, and the inner heat-conducting rigid frame 300 is provided with the second hole 301, when the first hole 4201, the through hole 1011 and the second hole 301 are coaxially arranged, the bolt on the supporting leg 420 can be sequentially threaded through the first hole 4201, the through hole 1011 and the second hole 301, and then locked and connected to the nut on the inner heat-conducting rigid frame 300, so that the outer heat-conducting rigid frame 400, the instrument mounting frame 100 and the inner heat-conducting rigid frame 300 can be tightly connected together.

[0040] Referring to Figure 2 and Figure 3In some embodiments, the control circuit board assembly 210 includes a circuit board body 2110 and a plurality of power amplifier elements 2120. The circuit board body 2110 is fixed at the opening 4101 of the shell portion 410. The plurality of power amplifier elements 2120 are installed on the circuit board body 2110 and are in contact with the inner wall of the shell portion 410. It can be understood that, since the circuit board body 2110 is fixed at the opening 4101 of the shell portion 410, the plurality of power amplifier elements 2120 installed on the circuit board body 2110 can be in contact with the inner wall of the shell portion 410, so that the power amplifier elements 2120 can exchange heat with the shell portion 410 more efficiently, and ultimately further improve the heat dissipation efficiency of the control circuit board assembly 210. The power amplifier elements 2120 can be bipolar field effect tubes, electronic tubes, or the like.

[0041] Referring to Figure 3 In some embodiments, a plurality of screw seats 4110 are formed in the shell portion 410. Each corner of the circuit board body 2110 corresponds to the position of a screw seat 4110, and the circuit board body 2110 is fixedly connected to each screw seat 4110 by a screw 2111. It can be understood that, since each corner of the circuit board body 2110 is arranged one by one corresponding to each screw seat 4110 formed in the shell portion 410, each corner of the circuit board body 2110 can be fixedly connected to a corresponding screw seat 4110 by a screw 2111. Specifically, each screw 2111 is screwed into the corresponding screw seat 4110 through the through hole in the corresponding corner of the circuit board body 2110, so that the circuit board body 2110 is fixedly connected to the shell portion 410.

[0042] Referring to Figure 2 In some embodiments, the inclination angle of the supporting leg 420 is 30° to 45°. It can be understood that, since the inclination angle of the supporting leg 420 is 30° to 45°, an appropriate angle can be maintained with the inclined display screen body 200, so as to better bear the weight of the display screen body 200. Specifically, the inclination angle of the supporting leg 420 can be 30°, 40°, 45°, etc., which is not limited herein, and can be replaced as needed by those skilled in the art.

[0043] Referring to Figure 2 In some embodiments, the display screen mounting structure for engineering vehicles further includes a protective cover 500 installed at the mounting position 101 and covering the supporting leg 420. It can be understood that, by covering the supporting leg 420 with the protective cover 500 installed at the mounting position 101, the supporting leg 420 can be protected, so as to achieve the effect of waterproofing and dustproofing.

[0044] Referring to Figure 2In some embodiments, the inner heat-conducting rigid frame 300 and / or the outer heat-conducting rigid frame 400 are both aluminum alloy frames. It can be understood that, since the outer heat-conducting rigid frame 400 is an aluminum alloy frame, not only can the heat-conducting property of the aluminum alloy frame be used to accelerate the heat dissipation of the control circuit board assembly 210, but also the rigidity of the aluminum alloy frame can be used to improve the overall support effect on the control circuit board assembly 210. Since the inner heat-conducting rigid frame 300 is an aluminum alloy frame, not only can the heat-conducting property of the aluminum alloy frame be used to quickly conduct the heat of the control circuit board assembly 210 out, but also the rigidity of the aluminum alloy frame can be used to improve the overall support effect on the instrument mounting frame 100.

[0045] Referring to Figure 2 In one embodiment, the display screen body 200 includes a main screen 230, a housing 220, and a control circuit board assembly 210, and the control circuit board assembly 210 and the main screen 230 are both installed in the housing 220.

[0046] Referring to Figures 1 to 2 The present disclosure also provides a vehicle-mounted anti-vibration instrument table including the display screen mounting structure for engineering vehicles of any of the above embodiments. It can be understood that, by applying the display screen mounting structure for engineering vehicles of the present disclosure to the vehicle-mounted anti-vibration instrument table, since the inner heat-conducting rigid frame 300 is fixedly installed in the interior of the vehicle body of the engineering vehicle, and part of the inner heat-conducting rigid frame 300 is attached to the inner surface of the instrument mounting frame 100, the entire instrument mounting frame 100 can be stably supported by the inner heat-conducting rigid frame 300, so that the entire instrument mounting frame 100 can move synchronously with the vehicle body of the engineering vehicle. Since the first part of the outer heat-conducting rigid frame 400 on the mounting site 101 is fixedly connected to the instrument mounting frame 100, and the second part of the outer heat-conducting rigid frame 400 is embedded in the interior of the display screen body 200 and fixedly attached to the control circuit board assembly 210 of the display screen body 200, the connection strength between the control circuit board assembly 210 and the instrument mounting frame 100 can be enhanced by the outer heat-conducting rigid frame 400, the shaking amount of the control circuit board assembly 210 relative to the vehicle body of the engineering vehicle can be reduced, and the line connection on the control circuit board assembly 210 can be more stable. At the same time, after the outer heat-conducting rigid frame 400 is attached to the control circuit board assembly 210, the heat generated by the control circuit board assembly 210 during operation can be conducted out to the inner heat-conducting rigid frame 300, further improving the heat dissipation efficiency of the control circuit board assembly 210.

[0047] Compared with the prior art, the present disclosure has at least the following advantages:

[0048] The display screen mounting structure for the engineering vehicle can stably support the whole instrument mounting rack 100 through the inner heat-conducting rigid frame 300, so that the whole instrument mounting rack 100 can move synchronously with the body of the engineering vehicle. The first part of the outer heat-conducting rigid frame 400 is fixedly connected to the instrument mounting rack 100, and the second part of the outer heat-conducting rigid frame 400 is embedded in the display screen body 200 and fixedly connected to the control circuit board assembly 210 of the display screen body 200. In this way, the outer heat-conducting rigid frame 400 can enhance the connection strength between the control circuit board assembly 210 and the instrument mounting rack 100, reduce the shaking of the control circuit board assembly 210 relative to the body of the engineering vehicle, and further stabilize the circuit connection on the control circuit board assembly 210. At the same time, after the outer heat-conducting rigid frame 400 is fixedly connected to the control circuit board assembly 210, the heat generated by the control circuit board assembly 210 during operation can be conducted to the inner heat-conducting rigid frame 300, further improving the heat dissipation efficiency of the control circuit board assembly 210.

[0049] The above-described embodiments only express several implementation manners of the present disclosure, and the description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the utility model patent. It should be noted that, for ordinary skilled persons in the art, without departing from the concept of the present disclosure, several modifications and improvements can be made, which all belong to the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure patent should be subject to the appended claims.
