[0002] With the advancement and development of science and technology, the functions carried by vehicle-mounted navigation systems are becoming more and more diverse, and these applications require debugging and verification of navigation equipment during the development stage to ensure that there will be no problems when the user uses the navigation system after it is installed in the vehicle. When debugging and verifying the navigation system, in order to facilitate operation, it is usually necessary to adjust the tilt angle of the navigation system, or even to stand the navigation system upright. The invention patent with publication number CN106289321A discloses a navigation system test fixture, including a base, a clamping device and a support seat, the rear end of the support seat is hinged to the base; the support seat includes a plug for connecting to the navigation system socket, and the clamping device is fixed on the support seat; the support seat includes a bottom plate and two vertical plates, and the two vertical plates are arranged on both sides of the bottom plate; the rear end of the bottom plate is hinged to the base; the clamping device includes two sets of clamping mechanisms, and the clamping mechanism includes a clamping cylinder and a clamping rod; the clamping cylinder is vertically arranged above the bottom plate, located outside the vertical plate side; the clamping rod is L-shaped, including a crossbar and a downward vertical rod, the crossbar is fixed to the upper end of the clamping cylinder piston rod, the crossbar extends into the inner side of the vertical plate, and the vertical rod is located on the inner side of the vertical plate; the support seat includes a rear plate and a rear plate driving mechanism, and the front end surface of the rear plate includes a plurality of the plugs; the rear plate driving mechanism includes two rear plate cylinders and two sets of linear guide pairs; the guide rails of the linear guide pair are fixed above the bottom plate along the longitudinal direction of the fixture, and the slider of the linear guide pair is fixed to the lower end of the rear plate; the two rear plate cylinders are fixed on the outer side of the vertical plate, and the rear end of the rear plate cylinder piston rod is connected to the rear plate.

[0026] The beneficial effects of the utility model are:

[0027] Since the support frame and the base are rotatably connected and provided with a rotation locking mechanism, the support frame can be rotated on the base to adjust the tilt angle, and the support frame and the base are relatively fixed by the rotation locking mechanism after the tilt angle of the support frame is adjusted into place. When the all-in-one navigator or the split navigator screen is placed on the support frame, the navigator or the navigator screen placed thereon can be driven to rotate by rotating the support frame, thereby adjusting the tilt angle of the navigator or the navigator screen, and even the navigator or the navigator screen can be made upright, meeting the needs of debugging and verification or complying with the debugging and verification operating habits of the staff, thereby improving the convenience and safety of the debugging and verification operation, and helping to improve the work efficiency of debugging and verification.

[0028] Since the support frame is bent at a right angle (the longitudinal section is L-shaped), it is suitable for both an all-in-one navigator to be placed thereon for support and fixation, and a split navigator screen to be placed thereon for support and fixation. It also helps the navigator or navigator screen placed thereon to rotate with the support frame and is not likely to slip off the support frame and cause damage during rotation.

[0029] Since the vertical plate adopts a triangular plate, the structure of the base is simple and can provide stable support for the support frame.

[0030] Due to the setting of the clamping mechanism on the top surface of the base plate, when the navigator or the navigator screen is placed on the support frame, the navigator or the navigator screen can be clamped and fixed by the clamping mechanism to prevent the navigator or the navigator screen from moving or sliding off the support frame during the rotation of the support frame or the debugging and verification process.

[0031] Due to the arrangement of the arc-shaped groove on the front side end face of the bottom plate, a navigator or a navigator screen with an irregular bottom shape can be placed firmly on the support frame. For example, when a navigator or a navigator screen with a convex structure on the bottom is placed on the support frame, the convex structure can be placed or stuck in a suitable arc-shaped groove, and the arc-shaped groove can also help to organize the wiring harnesses used in the debugging and verification process. Adjacent wiring harnesses can be placed in arc-shaped grooves at suitable positions to avoid cross-entanglement and disorder of the wiring harnesses used in the debugging and verification process. Since the back plate is composed of two vertical plates with a spacing, a navigator or a navigator screen with an irregular back shape can be placed firmly on the support frame. For example, when the back of the navigator or the navigator screen is provided with a convex electronic component, the two side edges of the back of the navigator or the navigator screen can be supported by two vertical plates so that the convex electronic component is located between the two vertical plates, and this helps to dissipate heat from the navigator or the navigator screen during the debugging and verification process. The unique shape or structural design of the bottom plate and / or the back plate makes the navigator placement device suitable for debugging and verification of navigators or navigator screens with irregular appearance shapes.

[0032] The utility model has the advantages of simple structure, convenient operation, low cost and wide application range. BRIEF DESCRIPTION OF THE DRAWINGS

The support frame is located between the two vertical plates. The left and right sides of the back plate are respectively rotatably connected to the vertical plates on the corresponding sides and are provided with a rotation locking mechanism so that the support frame can rotate on the base. Adjust the tilt angle, and after the tilt angle of the support frame is adjusted to the right position, the support frame and the base are relatively fixed by the rotating locking mechanism. When the navigator or navigator screen is placed on the support frame, the navigator or navigator screen placed thereon can be driven to rotate by rotating the support frame, thereby adjusting the tilt angle of the navigator or navigator screen, and even making the navigator or navigator screen stand upright, meeting the needs of debugging and verification or conforming to the debugging and verification operation habits of the staff (for example, facilitating the observation of the content displayed on the screen), thereby improving the convenience and safety of the debugging and verification operation, and helping to improve the work efficiency of debugging and verification. The support frame is in a right-angle bend shape, which is suitable for both an integrated navigator placed thereon for support and fixation, and a split navigator screen placed thereon for support and fixation, and helps the navigator or navigator screen placed thereon to rotate with the support frame and is not easy to slide off the support frame and cause damage during the rotation process.

[0042] The width of the support frame is preferably matched with the spacing between the two vertical plates, allowing for assembly clearance to facilitate rotation. The support frame can be integrally formed or can be formed by two plates vertically fixedly connected, that is, the bottom end of the back plate is fixedly connected to the rear end of the bottom plate.

[0043] The rotational connection method between the support frame and the base can be: the left and right sides of the back plate are respectively provided with outwardly extending rotation shafts 7, the two rotation shafts are horizontally coaxially arranged, the two vertical plates are respectively provided with axial holes matching the rotation shafts, the two axial holes are horizontally coaxially arranged, the rotation shafts are inserted into the axial holes on the vertical plates on the corresponding sides, and the free rotation of the support frame on the base is realized by the mutually matching rotation shafts and axial holes.

[0044] The shaft hole preferably passes through the plate surface of the vertical plate, the length of the rotating shaft is greater than the thickness of the vertical plate, the rotating shaft extends outwardly from the outer plate surface of the vertical plate on the corresponding side, and the part of the rotating shaft extending from the vertical plate on the corresponding side is provided with an external thread, on which a knob 3 that can be tightly pressed against the outer plate surface of the vertical plate is screwed, forming the rotation locking mechanism. When it is necessary to rotate the support frame, the knob is loosened to move it away from the outer plate surface of the vertical plate on the corresponding side. After rotating the support frame to the target inclination angle, the knob is tightened to make it press against the outer plate surface of the vertical plate, thereby achieving locking and fixation between the support frame and the base; or, the rotating shaft and the corresponding The shaft hole damping rotation connection, that is, a damping member is provided between the rotating shaft and the corresponding shaft hole, the damping member serves as the rotation locking mechanism or plays a role of rotation locking through the damping member, the outer end of the rotating shaft is fixedly connected with a knob, the damping member can be fixed (for example, bonded) and embedded in the shaft hole by a damping sleeve (for example, a rubber or other sleeve structure with moderate flexibility or elasticity), the damping sleeve is provided with a center hole, the rotating shaft is inserted in the center hole of the damping sleeve, when the support frame needs to be rotated, the damping effect of the damping sleeve can be used, that is, the support frame can be pushed to rotate by hand, and the support frame can be kept stationary after the hand is released, which is convenient to use.

[0045] The inner end (horizontal inner end) of the rotating shaft can be fixedly connected to the corresponding side (left side or right side) of the back plate, and after tightening the knobs on both sides, the support frame is fixed.

[0046] As a preferred embodiment, the inner end of the rotating shaft is slidably connected to the corresponding side of the back plate, and the sliding direction is up and down. Figure 3 and Figure 4 As shown, a sliding groove 61 with a wide inside and a narrow outside is provided on the corresponding side of the back plate (the entire back plate or the corresponding side vertical plate 6 constituting the back plate), and the sliding groove can be a T-shaped groove, a dovetail groove or a circular (arc) groove (a groove with a main part having a cross section in the shape of an arc, see Figure 4For example, a slider 62 is provided in the slide groove, and the shaft passes through the opening of the slide groove, and its inner end is fixedly connected to the slider. Thus, the height of the back plate relative to the shaft (that is, relative to the vertical plate) can be adjusted by the relative sliding of the slider on the back plate to meet different usage requirements. When the knob is tightened, the knob pulls the slider outward (laterally outward) through the shaft, and presses against the side groove wall of the opening of the slide groove (such as Figure 3 and Figure 4 After the knob is loosened, the slider can slide relatively in the slide slot, thereby not only adjusting the inclination angle of the support frame, but also adjusting the height of the support frame.

[0047] Any other suitable rotation connection method and any other suitable rotation locking mechanism in the prior art may be used between the support frame and the base, for example, a bearing connection and a latch locking mechanism.

[0048] A horizontal connecting rod 4 is preferably fixedly connected between the two vertical plates, and the connecting rod is preferably vertically connected to the vertical plates, that is, the two vertical plates and the connecting rod connected between the two vertical plates constitute the base. The vertical plates are preferably triangular plates, and the triangular plates are regular triangular plates. Any side of the regular triangle serves as the bottom side of the vertical plates (or the base), which are placed on a table or tabletop when in use. The connecting rod is preferably connected to the lower part of the vertical plates. In this way, the structure of the base is simple and can provide stable support for the support frame.

[0049] The top tip of the vertical plate (the tip opposite to the bottom edge) is preferably in the shape of an arc, and the side edges between the top tip and the two bottom tips are preferably in the shape of a smooth curved surface with a concave middle portion, so as to avoid the tips of the vertical plate being too sharp, which may easily cause damage to staff or test equipment and items.

[0050] The axial hole is preferably arranged at the upper part of the vertical plate, that is, at the top tip of the vertical plate, and the rotating shaft is preferably arranged in the middle part of the back plate. Such an arrangement allows the support frame to have a larger rotation angle range on the base.

[0051] The front side end surface of the bottom plate is provided with a plurality of inwardly facing arc grooves 5, such as semicircular grooves, and the spacing between any two adjacent arc grooves is equal, and the plurality of arc grooves are evenly distributed on the front side end surface of the bottom plate. Such a configuration facilitates the stable placement of a navigator or a navigator screen with an irregular bottom surface shape on the support frame. For example, when a navigator or a navigator screen with a convex structure on the bottom surface is placed on the support frame, the convex structure can be placed or stuck in a suitable arc groove, and the arc groove also helps to regularize the wiring harness used in the debugging and verification process, and the adjacent wiring harnesses can be placed in the arc grooves at appropriate positions to avoid the wiring harnesses used in the debugging and verification process from being crossed and entangled.

[0052] The bottom plate is preferably provided with a clamping mechanism. When the navigator or the navigator screen is placed on the support frame, the navigator or the navigator screen can be clamped and fixed by the clamping mechanism to prevent the navigator or the navigator screen from moving or sliding off the support frame during the rotation of the support frame or during the debugging and verification process. The clamping mechanism preferably includes a transverse (along the left and right directions) slide groove and two sliders arranged on the top surface of the bottom plate. The sliders are in damping sliding cooperation with the slide groove. A transverse damping member can be arranged in the slide groove. The damping member is provided with a transverse track groove. The sliding portion of the slider is inserted into the track groove of the damping member. When the navigator or the navigator screen is placed on the support frame, the navigator or the navigator screen can be clamped from the left and right sides by sliding the two sliders. The navigator or the navigator screen is clamped and fixed by the damping effect of the damping member.

[0053] The clamping mechanism may also be any clamping mechanism suitable for clamping and fixing an object on a board or table in the prior art, such as a clamping claw mechanism.

[0054] The left and right ends of the rear side of the bottom plate are preferably provided with vertical plates 6 perpendicular to the bottom plate, with a spacing between the two vertical plates, and the two vertical plates constitute the back plate. Such an arrangement facilitates the navigator or navigator screen with an irregular back shape to be firmly placed on the support frame. For example, when the back of the navigator or navigator screen is provided with protruding electronic components, the two side edges of the back of the navigator or navigator screen can be supported by the two vertical plates, so that the protruding electronic components are located between the two vertical plates, and it is helpful to dissipate heat of the navigator or navigator screen during debugging and verification. The back plate can also be made of a single plate, and the plate surface is preferably provided with one or more through holes penetrating the plate surface, so as to facilitate the heat dissipation of the navigator or navigator screen during debugging and verification.

[0055] The unique shape or structural design of the bottom plate and / or the back plate makes the navigation display device suitable for debugging and verifying navigation devices or navigation screens with irregular appearance shapes, and has a wide range of applications.

[0056] According to actual needs, a side view screen 8 can be added. The side view screen can be a display or display device of any suitable form with a display screen and a short-range wireless communication module such as Bluetooth, which is used to receive the display data of the navigator through Bluetooth and other methods, and implement the same display as the navigator display screen or a split-screen display in coordination with the navigator display screen. The connection between the side view screen and the navigator can also be achieved by wired communication. A corresponding cable interface is set on the side view screen, and the navigator is connected through a cable. In this case, the side view screen may or may not be provided with a short-range wireless communication module such as Bluetooth.

[0057] A pull-out plate 9 may be provided at the bottom of the base, the pull-out plate is located between the two vertical plates, and the left and right sides thereof are slidably connected with the corresponding side vertical plates. This sliding connection may be achieved by a commercially available slide rail (assembly) 94, or a slide groove with a width inside and a narrowness outside may be provided on the inner side (lateral inner side) of the vertical plate. The slide groove may be a T-shaped groove, a dovetail groove, or a circular (arc) groove, etc. The corresponding side of the pull-out plate is provided with a slider located in the corresponding side slide groove and slidingly matched with the slide groove, and the sliding connection between the pull-out plate and the vertical plate is achieved by slidingly matching the slider with the slide groove. Elastic pins or top screws may be provided to achieve the positioning of the pull-out plate, and after the pull-out plate is pulled out (pulled forward) or pushed back to the appropriate position, the pull-out plate is fixed by the corresponding elastic pins or top screws. The top screw may be a butterfly screw to facilitate manual operation.

[0058] The side viewing screen is set on the pull-out board. When in use, the pull-out board is pulled forward, and pushed back when not in use. The height of the support frame (lower end height) is adjusted appropriately to avoid obstruction of the pull-out board and the side viewing screen. A side viewing screen can be set on the pull-out board, or two side viewing screens on the left and right can be set to facilitate multiple people to watch or to display different contents on split screens according to actual needs. The side viewing screen can be movably connected to the top of the pull-out board through a multi-degree-of-freedom hinge assembly to allow the side viewing screen to be placed flat on the pull-out board, and to allow the side viewing screen to be erected. After being erected, it can be rotated horizontally to face the desired direction.

[0059] See also Figure 5 , Figure 6 and Figure 7 For example, the side view screen is located above the drawer plate and can be hinged to the drawer plate through a multi-degree-of-freedom hinge assembly. The multi-degree-of-freedom hinge assembly includes a vertical rod 91, the lower end of which is connected to the drawer plate through a lower hinge 92. The lower hinge is a hinge that can rotate around a vertical line, for example, a common ball bearing (such as Figure 6 example), shaft-hole clearance fit structure or ball joint (such as Figure 5For example, the lower hinge can be set in the pull-out plate, and the column passes through the through hole on the pull-out plate above the lower hinge and extends upward. The upper end of the column is connected to the side view screen through the upper hinge 93. The upper hinge is a hinge that can rotate around a horizontal line. The upper hinge can be set on the lateral side behind the side view screen, or a notch 96 for accommodating the upper hinge can be set on the lateral side of the bottom surface of the side view screen. The shape and size of the notch should not prevent the side view screen from being erected and laid flat through the upper hinge (see Figure 6 and Figure 7 example).

[0060] As a preferred embodiment, the rotation axis of the upper hinge is parallel to the lateral side direction of the side viewing screen, and the distance (vertical distance) between the rotation axis of the upper hinge and the bottom surface of the side viewing screen is the same as the distance (vertical distance) between the rotation axis of the upper hinge and the corresponding side surface of the side viewing screen, and is adapted to the distance from the top surface of the pull-out plate (slightly larger than the distance from the top surface of the pull-out plate), so that when the side viewing screen is laid flat, the bottom surface of the side viewing screen is attached to the top surface of the pull-out plate, and when the side viewing screen is erected, the corresponding lateral side surface of the side viewing screen is attached to the top surface of the pull-out plate, so as to facilitate the stability of the side viewing screen. In this case, in order to ensure that the side viewing screen can be flipped (standing up or laying flat) by the upper hinge, the area 81 where the bottom surface of the side viewing screen and the corresponding side surface are connected can be set to a smoothly transitioned arc (arc shape), and the distance (vertical distance) from any point on the arc to the rotation axis of the upper hinge is not greater than the distance (vertical distance) from the bottom surface of the side viewing screen or the corresponding side surface to the rotation axis of the upper hinge. Usually, the arc can be a circular arc with a radian of π / 2 (see Figure 6 and Figure 7 example).

[0061] Usually the pull-out plate can be arranged below the connecting rod, and the setting height of the connecting rod (the space below it) should be adapted to the setting of the pull-out plate and the side view screen.

[0062] Unless otherwise specified or one preferred or optional technical means is a further limitation of another technical means, all preferred and optional technical means disclosed in the present utility model can be arbitrarily combined to form several different technical solutions.
