[0009] As a further embodiment of this utility model: the heat dissipation component includes a mounting bracket and a cooling fan, the mounting bracket being fixedly installed inside the groove, and the cooling fan being fixedly installed inside the mounting bracket.

[0010] As a further embodiment of this utility model: the fixing component includes a fixing stud and a fixing plate, the fixing stud is threaded through the interior of the fixing block, and the bottom of the fixing stud is fixedly connected to the fixing plate through a bearing. The fixing component is used to fix the drive motherboard.

[0011] As a further embodiment of this utility model: the number of the shock absorption components is six groups and they are arranged in a rectangular array. The damper is fixedly installed on the inner bottom wall of the outer shell. The top of the shock absorption spring and the damper are both fixedly connected to the fixed frame.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1-5 As shown, an LCD display terminal driver motherboard fixing structure with anti-loosening function includes a housing 1. A shock-absorbing component 2 is fixedly installed on the inner bottom wall of the housing 1. A fixing frame 3 is fixedly installed on the top surface of the shock-absorbing component 2. Through the setting of the fixing frame 3, the shock-absorbing spring 201 and the damper 202 dampen the fixing frame 3 and the driver motherboard 6, preventing the electronic components (such as solder joints and connectors) on the driver motherboard 6 from physical desoldering, poor contact of connectors, or loosening of fixing screws due to long-term vibration. The cooling fan 402 dissipates heat from the driver motherboard 6, and the heat is discharged from the heat dissipation mesh 11, achieving the effect of shock absorption and heat dissipation of the driver motherboard 6, and extending its service life.

[0026] A groove is provided in the middle of the top surface of the fixed frame 3. A heat dissipation component 4 is fixedly installed inside the groove. A connecting pipe 5 is fixed around the top surface of the fixed frame 3. A drive motherboard 6 is sleeved on the surface of the connecting pipe 5. A fixing block 7 is fixedly installed around the inner wall of the fixed frame 3. A fixing component 8 is threaded through the inside of the fixing block 7. The drive motherboard 6 is inserted into the connecting pipe 5 through the fixing component 8. Then, the fixing stud 801 is turned, which drives the fixing plate 802 to press down, so that the docking post 9 is inserted into the connecting pipe 5. The docking post 9 and the connecting pipe 5 are arranged horizontally in pairs to prevent the drive motherboard 6 from shifting laterally. The upper fixing plate 802 and the lower fixed frame 3 prevent the drive motherboard 6 from shifting vertically, forming a two-way locking to avoid frequent displacement that could cause the connection between the drive motherboard 6 and the power line to loosen. Two sets of docking posts 9 are fixedly installed on the bottom surface of the fixing component 8.

[0027] like Figure 4 As shown, the shock absorption assembly 2 includes a shock absorption spring 201 and a damper 202. The shock absorption spring 201 is fixedly installed on the inner bottom wall of the outer shell 1, and the damper 202 is sleeved inside the shock absorption spring 201.

[0028] By setting the shock absorption component 2, the shock absorption spring 201 and the damper 202 provide shock absorption for the fixed frame 3 and the drive motherboard 6, preventing the electronic components (such as solder joints and connectors) on the drive motherboard 6 from physical desoldering, poor contact of connectors, or loosening of fixing screws due to long-term vibration.

[0029] like Figure 5 As shown, the heat dissipation assembly 4 includes a mounting bracket 401 and a cooling fan 402. The mounting bracket 401 is fixedly installed inside the groove, and the cooling fan 402 is fixedly installed inside the mounting bracket 401.

[0030] The heat dissipation component 4 or the cooling fan 402 dissipates heat from the drive motherboard 6, and the heat is discharged from the heat dissipation mesh 11, thus playing the role of dissipating heat from the drive motherboard 6.

[0031] like Figure 3 As shown, the fixing component 8 includes a fixing stud 801 and a fixing plate 802. The fixing stud 801 is threaded through the interior of the fixing block 7, and the bottom of the fixing stud 801 is fixedly connected to the fixing plate 802 through a bearing.

[0032] By setting the fixing component 8, the drive motherboard 6 is plugged into the connecting pipe 5, and then the fixing stud 801 is turned to drive the fixing plate 802 to press down, so that the connecting post 9 is inserted into the connecting pipe 5, thereby fixing the drive motherboard 6.

[0033] like Figure 4As shown, the number of shock-absorbing components 2 is six and they are arranged in a rectangular array. The damper 202 is fixedly installed on the inner bottom wall of the outer shell 1. The tops of the shock-absorbing spring 201 and the damper 202 are both fixedly connected to the fixed frame 3.

[0034] The damper 202 serves to dissipate the energy stored in the shock-absorbing spring 201.

[0035] like Figure 3 As shown, an anti-slip pad 10 is fixedly installed on the bottom surface of the fixing plate 802. The anti-slip pad 10 is made of rubber.

[0036] The anti-slip pad 10 increases the friction between the fixing plate 802 and the drive motherboard 6.

[0037] like Figure 4 As shown, heat dissipation mesh 11 is fixedly installed on both sides of the surface of the outer shell 1, and the inside of the connecting pipe 5 is provided with a docking hole that matches the docking post 9.

[0038] The heat dissipation mesh 11 serves to dissipate heat.

[0039] The working principle of this utility model is as follows: The drive motherboard 6 is plugged into the connector 5, and then the fixing stud 801 is turned to drive the fixing plate 802 to press down, so that the docking post 9 is inserted into the connector 5. The docking post 9 and the connector 5 are arranged horizontally in pairs to prevent the drive motherboard 6 from shifting laterally. The upper fixing plate 802 and the lower fixing frame 3 prevent the drive motherboard 6 from shifting vertically, forming a two-way locking to avoid frequent displacement that could cause the connection between the drive motherboard 6 and the power line to loosen.

[0040] The shock-absorbing spring 201 and damper 202 dampen the fixed frame 3 and the drive motherboard 6, preventing the electronic components (such as solder joints and connectors) on the drive motherboard 6 from physical desoldering, poor contact of connectors, or loosening of fixing screws due to long-term vibration. The cooling fan 402 dissipates heat from the drive motherboard 6, and the heat is discharged from the heat dissipation mesh 11, which dampens and dissipates heat from the drive motherboard 6, extending its service life.

[0041] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
