[0035] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings. Several embodiments of the present invention are shown in the accompanying drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0036] Please refer to Figure 1 and Figure 2 As shown, an embodiment of the present invention provides an integrated screen, including an integrated screen body 10 and a sheet metal latch 60 and a spring clip locking device arranged on the integrated screen body 10. The integrated screen body 10 is fixed to the instrument panel body by the sheet metal latch 60 and the spring clip locking device.

[0037] In this embodiment, the integrated screen has no brim, and the length direction of the integrated screen is defined as the Y direction, the width direction of the integrated screen is defined as the Z direction, and the direction perpendicular to both the Y direction and the Z direction is the X direction. There are three sheet metal pins 60 and three spring clip locking devices, which are respectively arranged on both sides and the middle of the length direction of the integrated screen body 10, and each sheet metal pin 60 is arranged on one side of the spring clip locking device.

[0038] Please refer to Figure 3 The sheet metal latch 60 includes a fixing portion 61 and a latch portion 62 extending downward from the fixing portion 61. The fixing portion 61 is in the shape of a sheet and is used to be fixedly connected to the integrated screen body 10. The latch portion 62 is in the shape of a "7" and is arranged at the lower end of the integrated screen body 10. It does not contact the integrated screen body 10 and is used to be plugged into the frame hole of the instrument panel body 20. When the integrated screen is pre-assembled with the instrument panel body 20, the sheet metal latch 60 guides the integrated screen into the frame hole of the instrument panel body 20, thereby controlling the gap surface difference between the lower end of the integrated screen and the instrument panel body 20. At the same time, through a certain amount of interference between the sheet metal latch 60 at the lower part of the screen and the frame, the integrated screen is pre-tightened with the instrument panel body 20 at a certain position to ensure reliable fixation and prevent abnormal noise problems.

[0039] The pin part 62 of the middle sheet metal pin 60 is longer than the pin parts 62 of the sheet metal pins 60 on both sides. The sheet metal pin 60 is first guided into the middle hole of the instrument panel body 20 to control the misalignment in the Y direction and reduce the damage to the decorative parts of the instrument panel body 20 on both sides. At the same time, it also controls the Y-direction clearance between the lower part of the control screen and the decorative parts, and ensures the smooth locking of the Z-direction metal elastic sheet clamping and locking device at the upper end of the integrated screen.

[0040] Each of the sheet metal pins 60 vertically extends a pin base 70 in a direction away from the integrated screen body 10. A spherical metal pin 80 is provided on the pin base 70, and the spherical metal pin 80 protrudes from the surface of the pin base 70 close to the sheet metal pin 60. Correspondingly, a raised first decorative part 21 is provided on the instrument panel body 20. A positioning hole is provided on the upper end surface of the first decorative part 21, and the spherical metal pin 80 is inserted into the positioning hole to limit the X-direction and Y-direction displacements of the integrated screen, and at the same time helps the elastic sheet clamping and locking device to be smoothly clamped and engaged with the instrument panel.

[0041] A rubber buffer pad 90 is provided on the connection surface between the pin base 70 and the sheet metal pin. The shape of the rubber buffer pad 90 is L-shaped. The spherical metal pin 80 accommodates the Z-direction assembly tolerance of the integrated screen through the rubber buffer pad 90.

[0042] Please refer to Figures 4 to 7 As shown, the elastic sheet clamping and locking device includes an elastic sheet bracket 30 and a rotating locking elastic sheet 40 installed on the surface of the elastic sheet bracket 30. The elastic sheet bracket 30 is arranged along the width direction of the integrated screen body 10 and is perpendicularly riveted and fixed to the integrated screen body 10.

[0043] The rotating locking elastic sheet 40 includes a locking section 41 and a rotating section 43 extending upward from the end of the locking section 41. One end of the locking section 41 is fixedly connected to the elastic sheet bracket 30, and the other end is provided with a serrated part 411 for meshing with the instrument panel body 20. The serrated part 411 is provided with a plurality of serrations, and the plurality of serrations rise in a stepped manner in the direction of the elastic sheet bracket 30. A through hole 31 is provided on the elastic sheet bracket 30. The rotating section 43 extends out of the through hole 31 and the locking section 41 are respectively arranged on both sides of the elastic sheet bracket 30;

[0044] The locking section 41 is in a "C" shape with an opening facing the elastic sheet bracket 30, and includes a main body part 412 and two wing pieces 413. The two wing pieces 413 are respectively formed by inclining upward from both sides of the main body part 412, and the serrated part 411 is provided on the end surface of each wing piece 413.

[0045] Among them, a second decorative piece 22 is arranged on the instrument panel body 20, and a notch 221 is arranged on the side of the second decorative piece 22. The upper end surface of the notch 221 is an engaging surface engaged and fixed with the serrated portion 411. When in the assembled state, the serrated portion 411 is inserted into the notch 221 to engage and fix with the second decorative piece 22.

[0046] It can be understood that when the integrated screen is subjected to the Z-direction assembly force, the rotation locking spring piece is rotated by force and rotates along with the integrated screen in the Y-direction. When the lower sheet metal pin 60 is plugged into the instrument panel body 20, the rubber buffer pad 90 carried by the upper spherical metal pin 80 is compressed by force to control the assembly feel. The integrated screen reaches the assembly position, and the end face of each wing 413 is a stepped serrated portion 411 that engages with the instrument panel body 20 to limit the Z-direction displacement of the integrated screen, so that the integrated screen is firmly fixed on the instrument panel body 20.

[0047] The rotating section 43 includes a flat plate portion 431 and a supporting portion 432 extending perpendicularly from the bottom end of the flat plate portion 431 in a direction away from the spring clip bracket 30. The supporting portion 432 is close to the surface of the spring clip bracket 30 and is in contact with the special disassembly tool 100. The rotating section 43 is rotated in a direction away from the spring clip bracket 30 by the special disassembly tool 100, driving the locking section 41 to retract into the through hole 31 so that the locking section 41 is separated from the instrument body.

[0048] Please refer to Figure 7 The special disassembly tool 100 includes a disassembly handle 101 and a disassembly rod 102 integrally connected to the disassembly handle 101. The disassembly handle 101 is circular in shape and has a hand-holding hole. One side of the disassembly rod 102 is a chamfered surface 103. The chamfered surface 103 includes a vertical portion and an arcuate surface portion. The arcuate surface is used to abut against a component. The end of the disassembly rod away from the disassembly handle is a tip. A groove 104 is provided on the arcuate surface. The groove 104 is provided at the end of the disassembly rod 102 away from the disassembly handle 101. The upper end surface of the groove 104 is longer than the lower end surface.

[0049] It can be understood that an accommodating gap is provided between the abutment portion 432 and the spring clip bracket 30. The tip of the special disassembly tool is first inserted into the accommodating gap, and the arc surface in the beveled surface 103 abuts against the abutment portion 432. As the special disassembly tool continues to move downward, its beveled surface 103 abuts against the abutment portion 432, so that the gap between the abutment portion 432 and the spring clip bracket 30 gradually increases, and the abutment portion 432 rotates in a direction away from the spring clip bracket 30. At the same time, the locking segment 41 integrally connected to the rotating segment 43 rotates in a direction close to the spring clip bracket 30, and the locking segment 41 gradually shrinks into the through hole 31, so that the meshing portion 411 gradually disengages from the instrument body, and finally completely disengages, which is convenient for rework and repair.

[0050] Please refer to Figure 1 In this embodiment, a slide groove 11 adapted to the disassembly rod 102 is provided on the integrated screen, and a guide ring 12 is provided below the slide groove 11. The slide groove 11 and the guide ring 12 allow the disassembly rod 102 to be inserted vertically downward to prevent the disassembly rod 102 from tilting when moving downward. The integrated screen and the instrument panel can be separated by using the special disassembly tool. Please refer to Figure 7 The steps for using the special disassembly tool are as follows: hold the disassembly handle 101, insert the disassembly rod 102 along the -Z direction, first pass through the slide groove 11, continue downward and then pass through the guide ring 12, the beveled surface 103 of the disassembly rod 102 contacts the abutment portion 432, continue to insert downward, the rotating locking spring piece 40 begins to rotate along the Y direction, the serrated portion 411 retracts into the through hole, and the serrated portion 411 eventually gradually separates from the instrument panel body 20. When the abutment piece 433 enters the groove 104 of the special tool, the special disassembly tool is blocked and cannot continue to move downward. At this time, it also indicates that the serrated portion 411 is completely separated from the instrument panel body 20 and enters the unlocked state, which is convenient for disassembling and taking the integrated screen.

[0051] Please refer to Figure 6 In this embodiment, the wing 413 away from the integrated screen body 10 extends upwardly a vertical portion 42, and the vertical portion 42 can abut against the spring bracket 30. The vertical portion 42 allows the rotation locking spring 40 to abut against the spring bracket 30 in the initial state.

[0052] Please refer to Figure 5 In this embodiment, the inner wall of the spring bracket 30 extends a connecting portion in a direction away from the locking section 41, and the ends of the two connecting portions are connected by a horizontal bar portion 32, which is arranged above the connection point between the locking section 41 and the spring bracket 30. When the locking section 41 is retracted into the through hole 31, the horizontal bar portion 32 can prevent the lower end of the main body 412 from completely passing through the through hole 31.

[0053] In this embodiment, a stopper 33 extends downward from the top of the inner wall of the spring bracket 30, and the stopper 33 and the rotating section 43 are arranged on the same side. When the locking section 41 is retracted into the through hole 31, the stopper 33 can prevent the upper end of the main body 412 from completely passing through the through hole 31.

[0054] In this embodiment, a fixing bracket 50 is extended perpendicular to the spring bracket 30 in a direction away from the spring bracket 30, and the fixing bracket 50 is used to be fixedly connected to the integrated screen body 10. The fixing bracket 50 can increase the contact area between the spring bracket 30 and the integrated screen body 10, so that the spring bracket 30 is more firmly fixed on the integrated screen body 10, so as to realize the fixed connection between the integrated screen body 10 and the instrument panel body 20.

[0055] The steps of assembling and fixing the integrated screen of the present invention on the dashboard are as follows:

[0056] Step 1: insert the sheet metal latch 60 of the integrated screen into the frame of the instrument panel body 20 for pre-assembly;

[0057] Step 2: Slightly lift the integrated screen and observe the spherical metal latch 80 to make it enter the positioning hole of the first decorative piece 21 of the instrument panel;

[0058] Step three: wait until the three spherical metal pins 80 are fully engaged with the positioning holes of the dashboard body 20, apply assembly force to make the metal spring clip clamp locking device move in the -Z direction, rotate the locking spring to deform, wait for the integrated screen to move to the assembly position, the metal spring clip clamp locking device is clamped and fixed to the dashboard body 20, and the assembly is completed.

[0059] The steps of removing the integrated screen of the present invention from the dashboard are as follows:

[0060] Step 1: Insert the three special tools for disassembling the integrated screen into the accommodation gap between the abutment part 432 and the spring bracket 30 along the characteristic mark on the back of the integrated screen (note that the tool groove 104 points to the +Y direction) and abut against the abutment part 432, and continue to move downward. When a crisp "tick" sound is heard, it means that the metal spring is deformed by force and has been separated from the instrument panel and entered the unlocked state. The three special tools for disassembly need to be inserted at the same time to unlock;

[0061] Step 2: Apply a pulling force upward to completely disengage the three spherical metal pins 80 from the bowl-shaped positioning holes of the dashboard body 20 frame, and the metal spring clip locking device completely disengages from the dashboard body 20. The sheet metal pin 60 rotates around the dashboard body 20 frame, and the integrated screen body 10 is disengaged from the dashboard body 20. The entire disassembly process is completed.

[0062] In summary, the present invention provides a spring clip clamp locking device and an integrated screen containing the spring clip clamp locking device, the spring clip clamp locking device cooperates with the instrument panel body 20 to engage and clamp to limit the Z-axis displacement of the integrated screen, thereby ensuring the firmness of the integrated screen body 10 installed on the instrument panel body 20, and a special disassembly tool is used to abut against the abutment portion 432 to drive the rotating locking spring clip 40 to rotate, thereby driving the locking section 41 to retract into the through hole, thereby disengaging the serrated portion 411 from the instrument body, which is convenient for rework and repair.

[0063] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
