Description

Roof-top structure

The present invention relates to a rooftop structure coupled to the roof of a vehicle.

Usually in the case of taxis, a rooftop structure is installed on the roof of the vehicle. The rooftop structure of a taxi is usually installed with an indicator light (shade lamp), which serves the function of indicating that the vehicle is a taxi and at the same time informs the status of the taxi, such as whether a passenger is on board.

The rooftop structures of recent taxis also perform other additional functions in addition to the conventional functions described above. For example, advertisements may be displayed and exposed on a portion of the rooftop structure. Additionally, the brand of the taxi in question is displayed on the rooftop structure.

As described above, as rooftop structures are used for more diverse purposes, the size of the rooftop structures tends to be larger than the indicator lights (shades) of conventional taxis. In order to install such a large-sized rooftop structure on the roof of a vehicle, a method of installing two or more frame bars extending in the left and right directions of the vehicle in the front and rear directions and connecting the rooftop structure to the frame bars was widely used.

This coupling method using two frame bars has the advantage of being simple in structure, easy to install, and low in cost, but has the disadvantage that the joint may be damaged by lateral wind and the fuel efficiency of the vehicle is greatly reduced. In addition, since it is not structured to be integrated with the vehicle, it has the disadvantage of being less aesthetically pleasing.

Accordingly, the demand for a rooftop structure that can compensate for the above-mentioned shortcomings and can be equipped with a wide display area for displaying advertisements, etc. is increasing.

Figure 1 is a perspective view of the rooftop structure 100 of the present invention. Figure 2 is a plan view of the rooftop structure 100 of the present invention. Figure 3 is a side view of the rooftop structure 100 of the present invention. Figures 4 and 5 are enlarged perspective views of a portion of the rooftop structure 100 of the present invention.

The rooftop structure 100 of the present invention is a structure coupled to the roof of a vehicle. A typical vehicle has a roof that constitutes the ceiling of the interior space. The rooftop structure 100 of the present invention is coupled to the upper part of the roof and functions to install the display unit so that it is clearly visible from the outside.

Here, the display unit may be a printout displaying various information, an image display including a picture or photograph, or a display device capable of variably displaying electronic information. Examples of display devices may include LCD display devices, LED display devices, PDP display devices, OLED display devices, and AMOLED display devices.

The display unit 112 is coupled to the frame unit 111 of the rooftop structure 100. This rooftop structure 100 must stably support the frame portion 111 at the top of the roof. Specifically, the rooftop structure 100 must stably support the frame portion 111 not only against external forces in the forward and backward directions, which are the main travel directions of the vehicle, but also against external forces in the lateral direction. This is because the frame portion 111 receives not only external force due to acceleration or deceleration of the vehicle, but also external force due to wind.

The present invention is designed to stably support the frame portion 111 at the top of the roof, improve vehicle operation efficiency and have a sleek appearance compared to the conventional rooftop structure 100.

Hereinafter, specific components of the rooftop structure 100 of the present invention and their connection relationships will be described in detail.

The rooftop structure 100 of the present invention includes a body portion 110 and rear support portions 130 and 140.

The body portion 110 extends in the front-to-back direction (AA') of the loop. For example, the body portion 110 is preferably extended to a length of 0.5 to 1 times the length of the loop in the front-back direction.

The body portion 110 includes a frame portion 111 to which the display portion is coupled. The frame unit 111 may be combined with one or more display units 112. For example, the frame unit 111 may be combined with four display units, including a front display unit, a rear display unit, and left and right display units. To this end, the frame portion 111 may include a front frame portion, a rear frame portion, and left and right side frame portions that surround at least part of the four display portions. The front frame portion, the rear frame portion, and the left and right side frame portions may each be combined on the inside to form an opening for combining the display portion through which the display portion may be exposed to the outside. The front frame portion, the rear frame portion, and the left and right frame portions may all be formed in a vertical direction with respect to the ground or the roof.

The fact that four display units are coupled to the frame unit 111 is only an example, and in some cases, it is possible for a different number of display units to be coupled to the frame unit 111.

The body portion 110 may be formed to extend longer in the anteroposterior direction (AA') than in the lateral direction. Accordingly, in the case of the display unit coupled to the body portion 110, the display unit coupled to the left and right sides may have a larger area than the display unit coupled to the front and rear sides.

The body portion 110 further includes a front support portion 120 extending from the frame portion 111. The front support portion 120 may extend forward from the front end of the frame portion 111. Specifically, the front support portion 120 may extend in a protruding form from the bottom of the front end of the frame portion 111. Accordingly, the front support part 120 may have a lower height (thinner shape) than the frame part 111.

As particularly well shown in FIG. 3, the front support portion 120 may extend forward in a downward tilted state at the front end of the frame portion 111. For example, the front support portion 120 may be inclined downward at an angle of 5° to 35° at the front end of the frame portion 111. This means that the angle between straight line AA' and straight line C1C2 in FIG. 3 is an angle of 5° to 35°. Accordingly, the front support portion 120 can be tightly coupled to the roof of the vehicle. This is because, in many types of vehicles, the front portion of the roof is inclined at a predetermined angle toward the front lower side.

As particularly well shown in FIG. 3, the lower end of the body portion 110 may be formed with a curved surface corresponding to the curved surface of the loop. Accordingly, the body portion 110 can be coupled to the loop in close contact.

As particularly well shown in FIG. 4, the front support portion 120 may be continuously connected to the front frame portion 111a of the frame portion 111. The portion 121 where the front support portion 120 and the front frame portion 111a are connected to each other may be formed as a curved surface. The curved surface of the connected portion 121 may be connected to both the front support portion 120 and the front frame portion 111a with a smooth curved surface without being bent at an angle. By connecting the front support portion 120 and the front frame portion 111a, air resistance when moving forward of the rooftop structure 100 can be minimized and aesthetics can be improved.

The rear supports 130 and 140 may include a first rear support 130 and a second rear support 140 . The first rear support portion 130 may extend from the rear end of the body portion 110 to the left rear, and the second rear support portion 140 may extend from the rear end of the body portion 110 to the right rear.

The lower ends of the rear supports 130 and 140 are formed with a curved surface corresponding to the curved surface of the loop, so that they can be tightly coupled to the loop. Because of this, the lower end of the body portion 110 and the lower ends of the rear support portions 130 and 140 may be formed as continuous curved surfaces.

The rooftop structure 100 has three supports, including a front support part 120, a first rear support part 130, and a second rear support part 140. The three support parts each extend in different directions around the frame part 111 to firmly support the frame part 111 at the top of the loop. Specifically, the front support portion 120 extends forward from the front end of the frame portion 111, while the rear support portions 130 and 140 extend from the rear end of the frame portion 111 to the left and right rear, thereby supporting the frame portion 111. It can be supported in a balanced manner from multiple directions.

This rooftop structure 100 has an overall wedge shape that appears to be moving forward, so when combined with a vehicle, it can be integrated with the overall appearance of the vehicle and has the advantage of excellent aesthetics.

As particularly well shown in Figure 2, the first and second rear supports 130, 140 include a diagonal extension 131 and a lateral extension 132. In the attached drawings, both the first and second rear supports 130 and 140 are shown as including a diagonal extension 131 and a lateral extension 132, but in some cases, the first and second rear supports ( 130, 140), it is also possible for only one of them to have this characteristic.

Hereinafter, for convenience of explanation, the characteristics of the rear supports 130 and 140 will be described based on the first rear support 130.

The diagonal extension portion 131 extends from the rear end of the body portion 110 in the diagonal direction B1B2 with respect to the front-back direction AA′. For example, the diagonal extension portion 131 may extend diagonally to form an angle of 100° to 150° with the front direction. This means that the angle between straight line AA' and straight line B1B2 in FIG. 2 is 100° to 150°.

The lateral extension portion 132 is bent and extended from the rear end of the diagonal extension portion 131 in a direction (B2B3) approximately perpendicular to the front-back direction (AA'). For example, the lateral extension portion 132 may extend to form an angle of 75° to 105° with respect to the front-to-rear direction. This means that the angle between straight line AA' and straight line B2B3 in FIG. 2 is 75° to 105°.

The edge portion 133 forming the end of the lateral extension portion 132 preferably extends approximately parallel to the front-to-back direction (AA'). And the edge portion 133 is installed to fit the side end of the loop. Typically, the structure of the vehicle is located below the side end of the roof in a vehicle, and the rooftop structure 100 is coupled to the structure of the vehicle through a fastening member (not shown). Therefore, the rooftop structure 100 is preferably formed so that the edge portion 133 is aligned with the side end of the roof. As described above, if the edge portion 133 is formed parallel to the front-back direction (AA'), there is room for the space where the fastening member is located, and the end of the lateral extension portion 132 and the side end of the loop are integrated. When combined, it has the advantage of excellent aesthetics.

Due to the presence of the lateral extension portion 132, the rear support portions 130 and 140 are in close contact with the roof of the vehicle as a whole, making it easy to couple them. In some vehicles, the side ends of the roof of the vehicle may be formed to have a higher curvature than the center portion. In this case, in order for the rear supports 130 and 140 to be in close contact with the roof of the vehicle as a whole, the ends of the rear supports 130 and 140 must be designed to correspond to the curvature of the side ends of the roof. If the end portions of the rear supports (130, 140) continue to extend diagonally without the lateral extensions (132), the curvatures in the left and right directions as well as the curvatures in the front and rear directions must be precisely adjusted, making the structure more complex and requiring a higher cost during the manufacturing process. Precision is required. However, in the case where the above-described lateral extension portion 132 is located at the end portion of the rear support portion 130, 140, the lateral extension portion 132 need only be aligned with the loop centered on the curvature in the left and right directions, resulting in a simpler structure and relative efficiency during processing. It has the advantage of being able to have high tolerances.

The lateral extension portion 132 is preferably formed shorter than the diagonal extension portion 131. For example, the lateral extension portion 132 may extend to a length of 0.15 to 0.5 times that of the diagonal extension portion 131 . This takes into account the area of the side ends, which have a higher curvature than the center part of the roof of some vehicles.

The first and second rear supports 130 and 140 may have a cross-section similar to a streamlined shape to smooth air resistance in the front-back direction (AA'). In the attached drawings, both the first and second rear supports 130 and 140 are shown as having a cross-section similar to a streamlined shape, but in some cases, only one of the first and second rear supports 130 and 140 may be used. It is also possible to have these characteristics.

Hereinafter, for convenience of explanation, the characteristics of the rear supports 130 and 140 will be described with reference to the first rear support 130 with reference to FIG. 5.

Referring to FIG. 5, the first rear support portion 130 includes a front inclined portion 136, a flat portion 137, and a rear inclined portion 138.

The front inclined portion 136 is an inclined surface formed to be inclined toward the front. A flat portion 137 extends rearward from the top of the front inclined portion 136. The flat portion 137 may be formed to be approximately parallel to the ground or the roof. And at the rear end of the flat portion 137, a rear inclined portion 138 that is inclined toward the rear extends.

In this way, the front and rear sides of the rear supports 130 and 140 may be formed in an inclined form rather than standing vertically with respect to the ground or the roof. Accordingly, the cross-section (cross-section cut in the front-back direction) of the rear supports 130 and 140 may have a shape similar to a streamlined shape. This shape has the advantage of being able to further reduce resistance to air moving in the forward and backward directions.

In the attached drawings, the rear supports 130 and 140 are shown to have both a front slope 136 and a rear slope 138, but in some cases, only one of the two slopes 136 and 138 is provided. It is also possible to have it.

Basically, when the rooftop structure 100 is installed on a vehicle, it causes air resistance, so the vehicle's fuel efficiency is bound to decrease. In this situation, if air resistance is minimized by being closely attached to the roof and some parts have a similar streamlined shape as in the rooftop structure 100 of the present invention, the decline in fuel efficiency can be reduced. In the case of the conventional rooftop structure 100, it was estimated that the fuel efficiency of the vehicle was reduced by about 8%, but in the case of the rooftop structure 100 of the present invention, it was estimated that the fuel efficiency of the vehicle was reduced by only about 6%. . This means that the fuel efficiency of a vehicle equipped with the rooftop structure 100 of the present invention is about 2.3% superior to that of a vehicle installed with a conventional rooftop structure 100 that is commonly used. (Based on the basic fuel efficiency of a vehicle of 13.0 km/L, the fuel efficiency of a vehicle installed with the conventional rooftop structure 100 varies to 11.95 km/L, and the vehicle installed with the rooftop structure 100 of the present invention The fuel efficiency is changed to 12.23km/L. This figure may vary depending on the vehicle and test environment.)

The rooftop structure 100 may further include a packing portion 150 located in contact with the roof. Specifically, the packing part 150 is coupled to the lower ends of the body part 110 and the rear support parts 130 and 140. Therefore, when the rooftop structure 100 is coupled to the roof, the packing part 150 is located between the lower ends of the body part 110 and the rear supports 130 and 140 and the roof.

The packing part 150 is preferably made of a flexible material. For example, the packing part 150 may be formed of materials such as rubber, silicone, polyurethane, and epoxy. The packing part 150 may be partially deformed in shape by an external force applied while coupling the rooftop structure 100 to the roof, thereby allowing the body part 110 and the rear support parts 130 and 140 to come into close contact with the roof.

The body portion 110 and the rear supports 130 and 140 may not be manufactured in a shape that perfectly matches the roof of the vehicle due to errors occurring during the design process or manufacturing process. These errors can be corrected due to deformation of the packing unit 150. The body portion 110, the rear support portions 130, 140, and the roof can be sealed by this packing portion 150, thereby preventing water or other foreign substances from penetrating into the interior of the rooftop structure 100. You can.

In addition, it may be possible to install one rooftop structure 100 on two or more types of vehicles with different roof shapes by using the packing unit 150. Even in the case of vehicles with slightly different roof curvatures, etc., it may be possible for the rooftop structure 100 to be installed in close contact with the roof due to deformation of the packing portion 150.

The above-described rooftop structure 100 may be installed on a commercial vehicle such as a taxi to display the characteristics and status of the vehicle (indicating that the vehicle is a taxi, whether there are passengers in the taxi, the brand of the taxi, etc.), and may display advertisements, etc. It can also be displayed. However, the functions and uses of this rooftop structure 100 are not limited to those described above.

The technical features disclosed in each embodiment of the present invention are not limited to the corresponding embodiment, and unless they are incompatible with each other, the technical features disclosed in each embodiment may be combined and applied to other embodiments.

Therefore, in each embodiment, each technical feature is mainly explained, but unless the technical features are incompatible with each other, they can be applied in combination with each other.

The present invention is not limited to the above-described embodiments and the accompanying drawings, and various modifications and variations will be possible from the perspective of those skilled in the art to which the present invention pertains. Therefore, the scope of the present invention should be determined not only by the claims of this specification but also by equivalents to these claims.
