Description

Technical Field

[0001] This invention relates to a radar housing forming technology, and more particularly to a radar structure that prevents housing deformation. Prior Technology

[0002] The material, thickness, and shape of the housing in conventional radar structures, besides being used for product size control, also affect the radar antenna's output field pattern or cause attenuation. Conventional radar housing structures are manufactured using plastic injection molding. Therefore, during the injection molding process, the parts of the housing used to connect external terminals are subject to assembly constraints, such as the location of circuit board openings, connection height, and housing wall thickness. These connection points require a significant thickness, which can lead to shrinkage, air bubbles, incomplete filling, stress marks, and warping during curing. This results in uncontrollable dimensions, causing the housing to fail to meet the original manufacturer's requirements for the radar product.

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

[0004] To address the aforementioned problems, the present invention aims to provide a radar structure that allows the formed housing to have a better appearance.

[0005] A secondary objective of this invention is to provide a radar structure in which the dimensions of the formed housing can be controlled, thereby improving the yield of the housing.

[0006] The directions or similar terms used throughout this invention, such as "top," "inner," "outer," and "side," are primarily for reference to the directions in the accompanying diagrams. These directions or similar terms are only used to assist in explaining and understanding the various embodiments of this invention and are not intended to limit the invention.

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

[0008] The terms "combination," "integration," or "assembly" used throughout this invention mainly include those that can be separated without damaging the components after connection, or those that make the components inseparable after connection. These are terms that those with ordinary knowledge in the art can choose based on the material of the components to be connected or the assembly requirements.

[0009] The radar structure of the present invention includes: a housing having a connecting element, one open end of the connecting element being disposed outward from the housing, and one connecting end of the connecting element facing an accommodating space inside the housing; the housing 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 protruding from the open end; a second end of each of the pins protruding from the connecting end; the pins being arranged at intervals; and grooves formed at the open end and located between the pins; the extension direction of the depth of one of the grooves being substantially parallel to the extension direction of the first end of the pins; and a circuit board located in the accommodating space, the circuit board being electrically connected to the second ends of the pins.

[0010] Accordingly, the radar structure of the present invention has grooves of a predetermined depth between the pins. In this way, when the housing is solidified and molded, the injection material can be prevented from being too concentrated during molding, and problems such as short shots, shrinkage, bubbles, incomplete filling, stress marks, and warping deformation can be prevented. This achieves the effects of manufacturing a housing with a better appearance, effectively controlling the size of the housing, improving the yield of the housing, and meeting the original requirements of the radar product manufacturer.

[0011] The opening extends along a direction parallel to the pins to the accommodating space for a length that is 1.25 to 2.5 times the depth. Thus, the grooves, corresponding to different lengths, can be set to different depths, effectively preventing housing deformation.

[0012] The connecting element has an open end with a sidewall surrounding the open end, forming a hollow cylindrical space. Thus, the connecting element can be fitted with an external terminal through the sidewall for transmitting radar transmission and reception signals, effectively assembling radar driving components.

[0013] The total cross-sectional area of ​​the grooves accounts for 30-60% of the area of ​​the opening. This allows for a sufficient cutout area to be formed on the connecting element, enabling the pins to be stably spaced, resulting in a better appearance and better control over product dimensions.

[0014] Each pin is L-shaped, with its first end parallel to the circuit board and its second end perpendicular to the circuit board. This allows the external terminal to engage in a direction parallel to the circuit board, thus accommodating the radar's transmission direction and the space required for radar product installation.

[0015] Each pin is long and straight, with its first and second ends facing opposite directions and both perpendicular to the circuit board. This allows the external terminal to connect perpendicular to the circuit board, thus accommodating the radar's transmission direction and the space required for radar product installation.

[0016] The cross-sectional shape of each of these grooves can be the same or different, such as circular, square, or polygonal. This allows for precise control of the spacing between the pins, improving both appearance and dimensional control.

[0017] The cross-sectional shape of each of these grooves is T-shaped, inverted T-shaped, or curved. This allows for uniform thickness of the connecting element and is suitable for products with large spacing between the pins, thus enabling dimensional control.

[0018] The cross-sectional shape of these grooves is elongated or / and elongated elliptical. This simplifies the complexity of the mold core and is suitable for products with small spacing between the pins, thus simplifying the manufacturing process and saving costs.

[0019] The grooves have a closed, interconnected cross-sectional shape. This allows them to be used in products with small spacing between pins, saving material costs and thus achieving cost savings. Simple Explanation of the Diagram

[0021] To make the above and other objects, features and advantages of the present invention more apparent and understandable, preferred embodiments of the present invention are described below in conjunction with the accompanying drawings; in addition, those symbols that are used in different drawings are considered to be the same and their descriptions will be omitted.

[0022] Please refer to Figures 1-3, which show the first embodiment of the radar structure of the present invention. It includes a housing 1 and a circuit board 2, with the circuit board 2 located in an accommodating space S inside the housing 1.

[0023] The housing 1 has a connecting element 11. One open end 111 of the connecting element 11 is disposed outward from the housing 1, and one connecting end 112 of the connecting element 11 faces the accommodating space S inside the housing 1. Furthermore, the housing 1 has a plurality of pins 12 and a plurality of grooves 13 located on the connecting element 11. Each of the pins 12 extends from 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 the grooves 13 are formed at the open end 111 and located between the pins 12.

[0024] The extension direction of the depth D of each of the grooves 13 is approximately parallel to the extension direction of the first end 12a of the pins 12. The length T of the connecting element 11 is from the opening end 111 along a direction parallel to the aforementioned 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 may have different shapes and specifications depending on different radar products, the connecting element 11 may have different lengths T at different positions. That is, the different lengths T corresponding to the grooves 13 can be set with different depths D. The present invention is not limited to the value of the depth D of the grooves 13.

[0025] The cross-sectional shape of the grooves 13 in the housing 1 can be the same or different, such as circular, square or polygonal, and the present invention is not limited thereto. Furthermore, the total cross-sectional area 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 forms a draft angle with the depth direction, which is about 1° to 3°. In this way, a sufficient hollow area can be formed on the connecting element 11 to avoid the injection material being too concentrated when molding the housing 1, which would lead to short shots, bubbles and surface shrinkage marks. It is also easy to control the spacing between the pins 13, and the pins 13 can be stably and stably arranged at intervals in the opening end 111.

[0026] The connecting element 11 may also have a side wall 113, which surrounds the opening end 111 to form a hollow cylindrical space with the opening end 111. The connecting element 11 can be fitted with an external terminal (not shown) through the side wall 113, and the first end 12a of the pins 12 is electrically connected to the external terminal. The radar structure of the present invention can transmit radar transmission and reception signals through the external terminal. However, the present invention is not limited to the above-described connection method of the connecting element 11.

[0027] The circuit board 2 is electrically connected to the second end 12b of the pins 12, and can be electrically connected to an external driving device through the pins 12 and the external terminal to perform the functions of the circuit board 2, including: transmitting and receiving radar waves, and processing the transmitted and received radar waves. In the first embodiment, each pin 12 is L-shaped, with the first end 12a of each pin 12 parallel to the circuit board 2 and the second end 12b 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 be adapted to the radar transmission direction and the space where the radar product is installed.

[0028] Please refer to Figures 4 and 5, which show a second embodiment of the radar structure of the present invention. This embodiment is largely the same as the first embodiment described above. In this embodiment, the cross-sectional shape of the grooves 13 in the housing 1 can be formed as a T-shape, an inverted T-shape, or a curved shape. This allows for uniform thickness of the connecting element 11 and is suitable for products with larger spacing between the pins 12.

[0029] Please refer to Figures 6 and 7, which show the third embodiment of the radar structure of the present invention. This embodiment is largely the same as the first embodiment described above. In this embodiment, the cross-sectional shape of the grooves 13 of the housing 1 can be formed as a long strip or / and a long ellipse. This simplifies the complexity of the mold core and is suitable for products with small spacing between the pins 12.

[0030] Please refer to Figures 8 and 9, which show the fourth embodiment of the radar structure of the present invention. This embodiment is largely the same as the first embodiment described above. In this embodiment, the cross-sectional shape of the grooves 13 in the housing 1 can be formed into a closed and connected shape. This can be used in products with a small spacing between the pins 12, and saves material costs.

[0031] Please refer to Figure 10, which is the fifth embodiment of the radar structure of the present invention. This embodiment is largely the same as the first embodiment described above. In this embodiment, each pin 12 is long and straight. The first end 12a and the second end 12b of each pin 12 face opposite directions and are both perpendicular to the circuit board 2, so that the external terminal can be connected in a direction perpendicular to the circuit board 2. This is in accordance with the radar transmission direction and the space of the radar product.

[0032] In summary, the radar structure of the present invention has grooves of a predetermined depth between the pins. Thus, during the curing and molding of the housing, excessive concentration of injection material during molding can be avoided, and problems such as short shots, shrinkage, bubbles, incomplete filling, stress marks, and warping deformation can be prevented. This achieves the effects of manufacturing a housing with a better appearance, effectively controlling the size of the housing, improving the yield of the housing, and meeting the original requirements of the radar product manufacturer.
