Description

Technical Field

[0001] The present invention relates to a radar shell forming technology, and in particular to a radar structure for preventing shell deformation. Background Art

[0002] The material, thickness, shape and other specifications of the shell of the known radar structure are not only used for product size control, but also affect the field pattern of the radar antenna output or cause attenuation. The known radar shell structure is made by plastic injection molding. Therefore, during the injection molding process of manufacturing the shell, the part of the shell used to connect the external terminal is limited by assembly factors, such as: the position of the circuit board opening, the height of the connection position, the thickness of the shell wall, etc., so that the connection part of the shell must have a larger thickness. In this way, the shell will shrink, bubble, incomplete filling, stress marks, warping and deformation during curing, which makes the size of the shell impossible to control, resulting in the shell not meeting the original factory setting requirements of the radar product.

[0003] In view of this, the known radar structure still needs to be improved. Summary of the invention

[0004] To solve the above problems, an object of the present invention is to provide a radar structure which can make the formed shell have a better appearance.

[0005] Another object of the present invention is to provide a radar structure, which can control the size of the molded shell to improve the yield rate of the shell.

[0006] The directions or their approximate terms described throughout the present invention, such as "upper", "inner", "outer", "side", etc., are mainly with reference to the directions of the attached drawings. Each direction or its approximate terms are only used to assist in the description and understanding of the various embodiments of the present invention, and are not used to limit the present invention.

[0007] The elements and components described throughout the present invention use the quantifiers "a" or "an" for convenience only and to provide a general meaning of the scope of the present invention; they should be interpreted in the present invention as including one or at least one, and a single concept also includes plural cases, unless it is obvious that it means otherwise.

[0008] The similar terms such as "combination", "assembly" or "assembly" described in the present invention mainly include the connection that can be separated without damaging the components, or the connection that makes the components inseparable, which can be selected by those with ordinary knowledge in the field according to the materials of the components to be connected or the assembly requirements.

[0009] The radar structure of the present invention comprises: a shell having a connecting element, an open end of the connecting element being arranged outward from the shell, a connecting end of the connecting element facing an accommodating space inside the shell, the shell having a plurality of pins and a plurality of grooves located on the connecting element, each of the pins extending from the open end of the connecting element to the connecting end, a first end of each of the pins being exposed at the open end, and a second end of each of the pins being exposed at the connecting end, a plurality of the pins being arranged at intervals, each of the grooves being formed at the open end and being located between each of the pins, and an extending direction of the depth of each of the grooves being parallel to an extending direction of the first end of each of the pins; and a circuit board located in the accommodating space, the circuit board being electrically connected to the second end of each of the pins.

[0010] Accordingly, the radar structure of the present invention has grooves of predetermined depth between each of the pins. In this way, when the shell is solidified and formed, it can avoid excessive concentration of the shot material during molding, and can prevent the formation of short shots, shrinkage, bubbles, incomplete filling, stress marks, warping and other problems. It can achieve the effects of manufacturing the shell with a better appearance, effectively controlling the size of the shell, improving the yield of the shell, and meeting the original factory setting requirements of the radar product.

[0011] The opening end is set to a length from the accommodating space along a direction parallel to each of the pins, and the length is 1.25 to 2.5 times the predetermined depth. In this way, the lengths of the grooves corresponding to different sizes can be set to predetermined depths of different depths, which has the effect of preventing the shell from deforming.

[0012] The opening end of the connecting element has a side wall surrounding the opening end to form a hollow cylindrical space with the opening end. In this way, the connecting element can be connected to an external terminal through the side wall to transmit radar transmission and reception signals, and has the effect of assembling radar driving components.

[0013] The sum of the cross-sectional areas of the plurality of grooves accounts for 30 to 60% of the area of ​​the opening end. In this way, a sufficient hollowed-out area can be formed on the connecting element, and each of the pins can be stably spaced apart, which has the effect of manufacturing a better appearance and controlling the product size.

[0014] Each of the pins is L-shaped, with a first end parallel to the circuit board and a second end perpendicular to the circuit board. In this way, the external terminal can be connected in a direction parallel to the circuit board, which has the effect of matching the radar emission direction and the space where the radar product is set.

[0015] Each of the pins is long and straight, and the first end and the second end of each of the pins face opposite directions and are perpendicular to the circuit board. In this way, the external terminal can be connected to the circuit board in a perpendicular direction, which has the effect of matching the radar emission direction and the space where the radar product is set.

[0016] The cross-sectional shapes of the grooves are the same or different circular, square or polygonal shapes. In this way, the spacing between the pins can be precisely controlled, which has the effect of improving the appearance and controlling the size.

[0017] The cross-sectional shape of each groove is a T-shaped, inverted T-shaped, or curved arc shape. In this way, the thickness of the connecting element can be made uniform, and it is suitable for products with large spacing between each pin, and has the effect of controlling the size.

[0018] The cross-sectional shape of each groove is a long strip or / and a long ellipse, so that the complexity of the mold core can be simplified, and it is suitable for products with a small spacing between each pin, which has the effect of simplifying the process and saving costs.

[0019] The cross-sectional shape of each groove is a closed and connected shape, so it can be used for products with small spacing between each pin, and saves material cost, which has the effect of saving cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In order to make the above and other purposes, features and advantages of the present invention more obvious and easy to understand, the preferred embodiments of the present invention are specifically cited below and described in detail with reference to the accompanying drawings; in addition, those marked with the same symbols in different drawings are regarded as the same and their descriptions are omitted.

[0032] Please refer to Figures 1 to 3, which are a first embodiment of the radar structure of the present invention, including a shell 1 and a circuit board 2, wherein the circuit board 2 is located in a accommodating space S inside the shell 1.

[0033] The shell 1 has a connecting element 11, an open end 111 of the connecting element 11 is set outward from the shell 1, and a connecting end 112 of the connecting element 11 faces the accommodating space S inside the shell 1. The shell 1 has a plurality of pins 12 and a plurality of grooves 13 located on the connecting element 11, and each of the pins 12 passes through the open end 111 of the connecting element 11 to the connecting end 112. Specifically, a first end 12a of each of the pins 12 is exposed at the open end 111, and a second end 12b of each of the pins 12 is exposed at the connecting end 112. The pins 12 are arranged at intervals, and each of the grooves 13 is formed on the open end 111 and is located between each of the pins 12.

[0034] The extension direction of a depth D of each of the grooves 13 is parallel to the extension direction of the first end 12a of each of the pins 12. A length T of the connecting element 11 is set from the open end 111 along a direction parallel to the above-mentioned extension direction to the accommodating space S. The length T is preferably 1.25 to 2.5 times the depth D of the corresponding groove 13. Since the housing 1 and the connecting element 11 have different shapes and specifications according to different radar products, the connecting element 11 can have different sizes of lengths T at different positions, that is, each of the grooves 13 corresponds to a length T of different sizes, and the depths D of different depths can be set. The present invention is not limited to the value of the depth D of each of the grooves 13.

[0035] The cross-sectional shapes of the grooves 13 of the housing 1 may be the same or different circular, square or polygonal shapes, etc., which are not limited by the present invention. In addition, the sum of the cross-sectional areas of the grooves 13 preferably accounts for 30 to 60% of the area of ​​the opening end 111, and the inclined surface in each groove 13 and the depth direction have a draft angle of about 1° to 3°. In this way, a sufficient hollowing area can be formed on the connecting element 11 to avoid excessive concentration of the ejected material during molding of the housing 1, which may lead to short shots, bubbles and surface shrinkage marks, and it is easy to control the spacing between the pins 13, and each pin 13 can be stably spaced and arranged on the opening end 111.

[0036] The connecting element 11 may further include a side wall 113, which surrounds the open end 111 to form a hollow cylindrical space with the open end 111. The connecting element 11 may be sleeved with an external terminal (not shown) through the side wall 113, and the first end 12a of each of the pins 12 is electrically connected to the external terminal. The radar structure of the present invention may transmit radar transmission and reception signals through the external terminal. However, the present invention is not limited to the above-mentioned joining method of the connecting element 11.

[0037] The circuit board 2 is electrically connected to the second end 12b of each of the pins 12, and can be electrically connected to an external driving device through each of the pins 12 and the external terminals to perform the functions of the circuit board 2, including: transmitting and receiving radar waves, and performing signal processing on the transmitted and received radar waves. In the first embodiment, each of the pins 12 is L-shaped, the first end 12a of each of the pins 12 is parallel to the circuit board 2, and the second end 12b is perpendicular to the circuit board 2, so that the external terminal can be connected in a direction parallel to the circuit board 2, which can match the radar transmission direction and the space where the radar product is set.

[0038] Please refer to Figures 4 and 5, which are the second embodiment of the radar structure of the present invention. This embodiment is substantially the same as the first embodiment. In this embodiment, the cross-sectional shape of each groove 13 of the housing 1 can be formed into a T-shaped, inverted T-shaped, or curved arc shape. The thickness of the connecting element 11 can be made uniform, and it is suitable for products with large spacing between each pin 12.

[0039] Please refer to Figures 6 and 7, which are the third embodiment of the radar structure of the present invention. This embodiment is substantially the same as the first embodiment. In this embodiment, the cross-sectional shape of each groove 13 of the housing 1 can be formed into a long strip or / and an oblong shape. This can simplify the complexity of the mold core and is suitable for products with a small spacing between each pin 12.

[0040] Please refer to Figures 8 and 9, which are the fourth embodiment of the radar structure of the present invention. This embodiment is substantially the same as the first embodiment. In this embodiment, the cross-sectional shape of each groove 13 of the housing 1 can be formed into a closed and connected shape. It can be used for products with a small spacing between each pin 12, and saves material costs.

[0041] Please refer to FIG. 10 , which is a fifth embodiment of the radar structure of the present invention. This embodiment is substantially the same as the first embodiment described above. In this embodiment, each of the pins 12 is of a long straight shape, and the first end 12 a and the second end 12 b of each of the pins 12 face opposite directions and are perpendicular to the circuit board 2, so that the external terminal can be joined in a direction perpendicular to the circuit board 2, which can match the radar emission direction and the space in which the radar product is set.

[0042] In summary, the radar structure of the present invention has grooves of predetermined depth between each of the pins. In this way, when the shell is solidified and formed, it can avoid excessive concentration of the injection material during molding, and can prevent the formation of short shots, shrinkage, bubbles, incomplete filling, stress marks, warping and other problems. It can achieve the effects of manufacturing the shell with a better appearance, effectively controlling the size of the shell, improving the yield of the shell, and meeting the original factory setting requirements of the radar product.
