Description

[0001] A NEW RADAR BOX DESIGN

[0002] TECHNICAL FIELD OF INVENTION

[0003] The present invention relates to a new radar box design. The invention specifically involves an improvement related to a radar box design which is highly efficient, easy and fast to manufacture, easy to install, particularly engineered for positioning radars in moving vehicles, with a focus on the automotive industry. The radar box of the invention is designed to minimize electrical and environmental interference affecting the antenna of the radar sensor.

[0004] BACKGROUND OF INVENTION

[0005] The application of radar for detecting approaching objects, measuring speed, or determining distance is used in many fields. The use of radar is becoming increasingly widespread, especially in aviation and maritime, and particularly in automotive technologies. Various systems have been developed in order to facilitate tasks and enhance safety, including radar sensors that detect vehicles approaching from the front, rear, and other sections of a vehicle, collision avoidance mechanisms, and parking assistance features. The antennas in these sensors, crucial for measuring distance or speed, are placed at strategic locations around the vehicle, including the front, back, and at peripheral edge and corner spots for optimal functionality. However, the addition of more sensors or antennas does not proportionally expand the monitored area, and employing numerous sensors incurs significant costs. To prevent this, antennas and electronic boards, which are positioned on a body triangularly, so as to scan a very wide angle (for example, an angle of 180 degree) range can be used. Instead of using a large number of sensors with these triangular-shaped bodies, the use of radar sensors containing antennas that scan at a wider angle can be a solution. Yet, the manufacturing techniques for these triangular structures are often outdated. The production costs for these radar enclosures, predominantly crafted through casting or metalworking, are elevated due to the extensive material usage and numerous manufacturing steps. In the prior art, the Chinese Patent no CN111610493 discloses a configuration related with a m illimetric radar application to a vehicle. It can be seen that the said radar application body has a triangular structure. However, the prevailing opinion is that the system will not be efficient enough for the desired ease of production and practical application.

[0006] Also, in the Chinese patent no CN210199309, which is another document in the prior art, millimetric radar application to a vehicle can be seen. Although it is seen that the radar applied in this patent and its body have a triangular structure, there is no detailed construction, and it is thought that this happens because the patent does not focus on the body.

[0007] Another document related to the subject in the prior art is the Chinese patent no CN210047409. In said patent, it is seen that positioning of millimetric radar applied to a vehicle, in an adjustable box is mentioned.

[0008] TECHNICAL PROBLEMS ADDRESSED BY THE INVENTION

[0009] In order to eliminate the disadvantages mentioned above, the present invention provides a radar box / enclosure embodiment comprising a main carrier body, a cover positioned at the top of the said main carrier body and at least one heat conduction column to carry an electronic board and to allow it to be positioned in a triangular shape, and a mounting column. The said box design provides a structure that minimizes electrical and environmental interference towards the antenna of the radar sensor, in addition to ease of production and material savings. Radome, which is the cover of the radar box, is a mechanical barrier that surrounds the millimeter wave radar antenna, insulates the radar antenna and equipment from environmental factors such as rain, wind, moisture, dust, etc., but provides the electromagnetic waves generated by radar transmitter and radiated to the external environment and / or coming to the radar receiver from the external environment, to pass with the least possible loss. This barrier is designed not to disrupt the antenna radiation pattern. For this reason, the present box design is made by a special material that is minimally damaged by environmental factors, in accordance with automotive standards. The thickness of this low-loss material in the antenna radiation direction of the box and the distance between the sensor and the cover are related to the wavelength at the operating frequency of the radar and the dielectric permeability of the radome material and are determined to provide the mentioned electromagnetic permeability.

[0010] An advantage of the radar box of the invention is a great ease of production and increased production speed. In the state of the art, instead of a "rough" triangular body processed on different machine tools, a single carrier sub-body, and in this sub-body, to help cooling by transferring the heat in the electronic board (and antenna) to the body and also to serve as a carrier, at least one heat transfer column is achieved. The said heat transfer column extends upwards from the lower body (preferably at a right angle to the lower body surface), with the middle body located almost in the middle of the lower body, and its top part contains a curved structure resembling a roof for the triangular inclined positioning of the electronic board. Similarly, it contains mounting columns at the edges and middle parts, both to ensure heat transfer and to mount the electronic board.

[0011] Another advantage of the radar box of the invention is that the product can be processed on machine tools as aluminum from a single axis with a new triangular design having a 180-degree scanning angle, due to the mechanical design. However, in the state of the art, it was necessary to make adjustments continuously and to process repeatedly in different axes. Therefore, there is a great speed and ease of production operations. Of course, the lightness of the material is a distinct advantage. Despite the heat transfer columns and montage columns in the radar box of the invention, the production speed and ease are increased. Columns (struts) are designed perpendicular to the reference surface, taking into account the mold opening direction. At once time for error-free and fast production operations with saw dust, a reference surface is made, and all studs and holes (holes required for assembly) are designed taking this reference surface into consideration. On the other hand, the dimensions of the struts planned for connection and heat transfer are reduced to minimize material usage and weight, and incorrect connection of the printed circuit board (PCB) is prevented with the method (Design pokayoke) used to prevent avoidable errors caused by people, machines, materials and methods that cause unnecessary resource consumption, and with this design made, interference between antennas is prevented by placing PCB angles so as to intersect at 90 degrees. The product design consists of case, cover, PCB and socket. Aluminum material is used in the case design of the product instead of metal, etc. The reason for using aluminum in designing the case is to provide the heat exchange of it with the thermal area on the PCB. Thus, it is ensured that it comes into contact with the areas inside the product that heats (for example, the processor and power areas). In this way, by transferring heat over aluminum, the product is prevented from overheating and the increase in temperature is reduced. A radome (cover suitable for the radar) design is made in accordance with electromagnetic principles in order to cause minimal disruption in the radiation pattern of the antenna on the radar (the signals coming out of the product reach the product without being distorted). In this design, a material complying with automotive standards with a thickness of 2.4 mm and a dielectric constant of 2.6 is used.

[0030] DETAILED DESCRIPTION OF THE INVENTION

[0031] The radar box of the present invention is basically a box or machine apparatus configuration in which the electronic board and antennas of the radars, known as millimetric radar in the automotive industry, is positioned. Although it is designed for millimetric radar and the automotive industry, it should not be forgotten that it can also be used in other sectors. Another point is that the pictures and figures used to explain the invention are only examples. Therefore, it should not be forgotten that there can be visual design freedom while preserving technical elements.

[0032] The radar box of the present invention is ideally illustrated in Figure-1 to describe the design created in its lower body fundamentally. The positioning of the electronic board with internal antenna or in different versions on the said lower body is shown in Figure-2 and Figure-3. Figure-4 shows a configuration, wherein the upper part of the said lower body is closed by the cover or radome (cover suitable for the radar).

[0033] The radar box of the invention comprises basically a lower body (1 ) serving as a carrier, the middle body (2) positioned on the upper part of the said lower body (1 ), at least one heat transfer column (3) positioned on the said lower body (1 ) or said middle body (2) for transferring heat from the electronic board (7) to the body and at the same time for assembly, at least one main carrier column (5) that serves to carry the electronic board (7) on the said lower body (1 ), and at least one connection protrusion (4) allowing the assembly of the said electronic board (7) to the body, and a cover (8) covering the upper part of the lower body (1 ) and the electronic board (7).

[0034] In the radar box of the present invention, the lower body (1 ) and the middle body

[0035] (2), together or separately, are preferably made of aluminum material. Preferably, the production method can be performed in milling machines by machining method. But this is not binding. There are heat transfer columns (3) in the upper part of the lower body (1 ) or in the middle body (2). The heat transfer columns (3) carry both the electronic board (7) and comprise a sloped heat transfer column bearing surface (3a) at the top, preferably in areas of high heating, to reduce the heat generated due to the heating of the electronic board (7). There can be several heat transfer columns

[0036] (3) in the lower body (1 ), the middle body (2), or at the junctions of both. The electronic board (7) is mounted here with preferably connection holes (6) on it. The connection holes (6) are connected with connection elements (preferably screws). The main carrier column (5) is preferably positioned perpendicularly at the edgemiddle part of the lower body (1 ). At the top, there are sloped carrier column surfaces (5a) on both sides for the electronic board (7) to rest and connect, and connection holes (6) are created on these surfaces. In the areas near the edge and corner areas of the lower body (1 ), there are connection protrusions (4) for connecting the electronic board (7). There are connection surfaces (4a), having inclined upper part, of connection protrusions (4) and there are connection holes (6) on these surfaces, for connecting the electronic board. The slopes of the heat transfer column bearing surface (3a), connection surface (4a) and carrier column surface (5a) are equal or almost equal. When the electronic board (7) rests and connects to these surfaces, it forms a triangle, allowing the millimeter radar to scan at a wide angle and efficiently. There is a cover (8) that covers the electronic board and other equipment mentioned or not mentioned here, which is mounted on the upper part of the lower body (3) and closes the box. The cover (8) is the part called the radome (radar- appropriate cover) in radar box design of radar equipment having antenna, that corresponds to the front face. The radome is a mechanical barrier that surrounds the millimeter-wave radar antenna; isolates the radar antenna and equipment from environmental factors such as rain, wind, humidity, dust, etc.; but allows the electromagnetic waves produced by the radar transmitter to be emitted to the external environment and / or coming from the external environment to the radar receiver to pass with the least possible loss. For this reason, the current box design is made of a special material that will damage minimally from environmental factors, in accordance with automotive standards. The thickness of this low-loss material on the side of the box where the antenna radiates and the distance between the sensor and the cover is determined in relation to the wavelength of the radar's operating frequency and the dielectric permittivity of the radome material, to ensure the mentioned electromagnetic permeability.

[0037] INDUSTRIAL APPLICATION OF THE INVENTION The radar box design of the present invention is preferably planned for millimetric radar in vehicles in the automotive industry. However, it can be used in any field, especially where a triangular-shaped electronic board and antenna must be positioned.
