Description

Technical Field

[0001] This application relates to the field of radar technology, and in particular to radar spraying tooling and radar spraying systems. Background Technology

[0002] With the development of vehicle electrification, radar sensors are being used more and more in automobiles (electric intelligent vehicles generally require 10 to 40 radar sensors). Depending on the application scenario, radar sensors can be installed, but are not limited to, on the front bumper, rear bumper, and rearview mirrors. Current solutions involve painting the exposed surfaces of the radar sensors with the same color as the vehicle body paint to ensure an aesthetically pleasing overall appearance.

[0003] To ensure the quality of the radar probe's paint, it needs to be painted and baked. For example, a primer / color paint / clear coat spraying process is used at 60℃~70℃ to improve paint quality. Because the radar probe is an electronic component, the cleanliness of the wiring harness is very important. If paint mist enters the wiring harness, it can easily lead to problems such as poor contact. The radar probe contains many electronic components such as circuit boards and sensors, which are easily damaged at temperatures ≥60℃.

[0004] Based on the above requirements, there is an urgent need for a painting fixture suitable for painting the exposed surface of radar probes, so as to reduce the adverse effects of the painting process requirements on other parts or components besides the exposed surface. Utility Model Content

The side plate is circumferentially disposed on the bottom plate, and the first heat insulation layer is disposed on the bottom plate. The height of the side plate is greater than or equal to the sum of the thickness of the bottom plate and the thickness of the first heat insulation layer.

Detailed Implementation

[0028] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are for illustrative purposes only and do not limit the scope of the application. Similarly, the following embodiments are only some, not all, embodiments of the present application, and all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present application.

[0029] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0030] In the description of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "setting," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can be mechanical connections or electrical connections; they can be direct connections or connections separated by an intermediate medium. For those skilled in the art, if directional indicators (such as up, down, left, right, front, back, etc.) are involved in the embodiments of this application, these directional indicators are only used to explain the relative positional relationships and movement of the components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indicators will also change accordingly.

[0031] This application first provides a radar spraying fixture, please refer to... Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of one embodiment of the radar spraying tooling of this application. Figure 2 yes Figure 1 An exploded view of the disassembled structure. (See diagram below.) Figure 1 and Figure 2 As shown, the radar coating fixture 10 includes a base 11 and a cover plate 12. The base 11 is provided with a plurality of grooves 114, each groove 114 being used to place the radar probe 13 to be coated; the cover plate 12 is provided with a plurality of openings 121 corresponding to the grooves 114.

[0032] The shape of the groove 114 corresponds to the shape of the outer shell of the radar probe 13. The groove 114 is used to accommodate the radar probe 13, and the surface of the radar probe 13 is exposed in the groove 114. The surface of the radar probe 13 includes an adjacent first surface 131a and a second surface 132a. The shape of the opening 121 corresponds to the shape of the first surface 131a. The cover plate 12 covers the base 11 so that the first surface 131a of the radar probe 13 is exposed in the opening 121 and sprayed.

[0033] Specifically, when the radar probe 13 is placed in the groove 114, the groove wall of the groove 114 is used to shield the sides and bottom of the radar probe 13, while exposing the upper surface of the radar probe 13. The upper surface of the radar probe 13 includes a first surface 131a and a second surface 132a. The first surface 131a is the exposed surface of the radar probe 13 when it is installed in a car, and it is the surface that needs to be painted. The second surface 132a is located to one side of the first surface 131a, and its height is less than that of the first surface 131a. When the cover plate 12 is closed on the base 11, the cover plate 12 is used to shield the second surface 132a of the radar probe 13 and expose the first surface 131a of the radar probe 13 through the opening 121, so that the painting equipment can paint the first surface 131a of the radar probe 13.

[0034] A plurality of grooves 114 are arranged in an array on the base 11, such that each groove 114 is at a certain distance from its adjacent grooves 114. Exemplarily, the array arrangement can be, but is not limited to, the following: multiple grooves 114 can be arranged in a circular trajectory around a central groove 114; multiple grooves 114 can be arranged in a rectangular array in two mutually perpendicular directions, such as 7 rows and 8 columns, 6 rows and 7 columns, or 6 rows and 6 columns, depending on the area of ​​the base 11 and the cover plate 12, the coating requirements of the radar probe 13, etc.; multiple grooves 114 can include multiple hexagonal arrangement groups, with six grooves 114 arranged along a hexagon, and adjacent hexagonal areas are joined together. Correspondingly, the plurality of openings 121 on the cover plate 12 are arranged in the same array as the grooves 114 on the base 11, and will not be described further here.

[0035] The shape of the groove 114 on the base 11 corresponds to the shape of the outer shell of the radar probe 13. The cross-sectional dimension of the groove 114 can be slightly larger than the cross-sectional dimension of the outer shell of the radar probe 13, so that the radar probe 13 can be accurately placed in the groove 114. When accommodating the radar probe 13, the groove 114 can seal off the other sides / bottom surfaces of the radar probe 13, except for the first surface 131a and the second surface 132a, through the groove wall, so as to reduce or avoid the adverse effects of paint mist on other parts during the spraying process.

[0036] In this embodiment, the radar coating fixture 10 exposes the surfaces of several radar probes 13 to be coated through the opening 121 via the cover plate 12, so as to ensure the consistency of paint quality and color of the first surface 131a of the radar probe 13 during coating. Other positions of the radar probe 13, except for the first surface 131a, are closed by the cover plate 12 and the groove 114, so as to reduce or avoid paint mist from entering other parts or components besides the exposed surface during the coating process, thereby improving the quality of the radar probe 13.

[0037] In one embodiment, please refer to Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of the structure of one embodiment of the base provided in this application. Figure 4 yes Figure 3 A sectional view along the BB section line. (Example) Figure 3 and Figure 4 As shown, the base 11 includes a base plate 111 and a first heat insulation layer 112. Several grooves 114 are disposed on the side of the first heat insulation layer 112 away from the base plate 111. The first heat insulation layer 112 is used to absorb the heat generated during the spraying process of the radar probe 13 to reduce the temperature of the radar probe 13.

[0038] Specifically, the first heat insulation layer 112 is disposed on the base plate 111. The first heat insulation layer 112 may be, but is not limited to, a heat insulation coating, a heat insulation material layer, a heat insulation aerogel layer, etc. For example, the heat insulation coating may be a ceramic coating or a reflective coating. The ceramic coating can reduce the transfer of heat from the external environment to the internal radar probe 13 through the heat insulation performance of the ceramic material. The reflective coating is used to reduce the heat radiation from the external environment. The heat insulation material layer is a heat insulation layer composed of composite materials. For example, using glass fiber reinforced composite materials to make the heat insulation layer can effectively isolate heat. Alternatively, the heat insulation material layer may be made of materials with fibrous structures such as asbestos, so that the resistance to heat conduction is increased by the fiber network formed by the interwoven fiber structures, and the convective transfer of heat is reduced by the still air in the fiber network, thus hindering the conduction of heat from the external environment to the internal radar probe 13.

[0039] During the painting process of the radar probe 13, since the radar probe 13 used in automobiles has high requirements for painting quality, the painting process needs to be carried out in a temperature environment of 60℃~70℃. In this embodiment, the radar painting fixture 10 absorbs the heat of the painting process through the first heat insulation layer 112, so as to isolate or reduce the heat exchange between the radar probe 13 and the external environment, reduce the temperature of the radar probe 13 during the painting process, further reduce the damage of the electronic components inside the radar probe 13 in the high temperature environment, and improve the reliability of the radar probe 13.

[0040] Optionally, the thickness of the first insulation layer 112 is greater than the thickness of the base plate 111.

[0041] Specifically, the base plate 111 can be a metal plate. Using a metal plate as the bottom layer of the base 11 can improve the mechanical strength of the base 11 and reduce damage to the radar coating fixture 10 caused by external impacts. The metal plate can also reflect and block heat transfer from the outside of the radar coating fixture 10. The thickness of the first heat insulation layer 112 is greater than the thickness of the base plate 111 to enhance the heat insulation performance of the first heat insulation layer 112, further reducing the temperature of the radar probe 13 during the coating process and reducing damage to the electronic components inside the radar probe 13 in a high-temperature environment.

[0042] Optionally, the thickness of the first insulation layer 112 is 21 mm, and the thickness of the base plate 111 is 0.8 mm.

[0043] In this embodiment, by setting the thickness of the first heat insulation layer 112 to 21mm and the thickness of the base plate 111 to 0.8mm, the thickness ratio between the first heat insulation layer 112 and the base plate 111 on the base 11 is moderate. The base plate 111 can provide sufficient mechanical strength for support and protection. Furthermore, the thickness of the first heat insulation layer 112 can effectively maintain a sufficient distance between the bottom of the groove 114 and the base plate 111, based on the setting of several grooves 114 to accommodate the radar probe 13. The first heat insulation layer 112 at the bottom of the groove 114 can provide sufficient heat insulation effect, ensuring that the groove wall of the groove 114 can fully wrap and insulate the radar probe 13.

[0044] Optionally, please see Figure 5 and Figure 6 , Figure 5 This is a schematic diagram of the structure of one embodiment of the cover plate provided in this application. Figure 6 yes Figure 5 A sectional view along section line AA. (See attached image.) Figure 5 and Figure 6As shown, the cover plate 12 also includes a top plate 122 and a second heat insulation layer 123. The cover plate 12 covers the base 11, and the second heat insulation layer 123 is located between the top plate 122 and the first heat insulation layer 112. The top plate 122 and the second heat insulation layer 123 are provided with a plurality of openings 121. The second heat insulation layer 123 is used to absorb heat during the spraying process to reduce the temperature of the radar probe 13 during spraying.

[0045] Specifically, when the cover plate 12 is closed on the base 11, the top plate 122, the second heat insulation layer 123, the first heat insulation layer 112, and the bottom plate 111 are stacked. The groove 114 is provided in the first heat insulation layer 112, and the opening 121 corresponds to the position of the groove 114. The groove wall formed by the first heat insulation layer 112 is used to shield the sides and bottom of the radar probe 13. The first heat insulation layer 112 can isolate or reduce the heat exchange between the sides and bottom of the radar probe 13 and the external environment.

[0046] The second heat insulation layer 123 has a first hole, and the top plate 122 has a second hole corresponding to the first hole. The first hole and the second hole are connected to form the aforementioned opening 121. When the cover plate 12 is closed on the base 11, the second heat insulation layer 123 is used to shield the second surface 132a of the radar probe 13 and expose the first surface 131a of the radar probe 13 through the first hole. The second heat insulation layer 123 can isolate or reduce the heat exchange between the second surface 132a of the radar probe 13 and the external environment.

[0047] Therefore, in this embodiment, the radar coating fixture 10 is configured with a structure consisting of a top plate 122, a second heat insulation layer 123, a first heat insulation layer 112, and a bottom plate 111 stacked together, so that all parts or components of the radar probe 13 except for the first surface 131a are covered by the heat insulation layer. Furthermore, when the applicant placed the radar coating fixture 10 of this embodiment in a 70°C process environment for a 20-minute baking test, the tested temperature of the radar probe 13 did not exceed 45°C. This means that the radar coating fixture 10 of this embodiment can effectively achieve heat insulation of the radar probe 13, ensuring that the internal temperature of the radar does not exceed 60°C, effectively reducing or preventing damage to the electronic components inside the radar probe 13 under high-temperature conditions.

[0048] Furthermore, the thickness of the second insulation layer 123 is greater than the thickness of the top plate 122.

[0049] Specifically, the top plate 122 can be a metal plate. Using a metal plate as the top layer of the cover plate 12 can improve the mechanical strength of the cover plate 12, thereby protecting the radar probe 13 inside the tooling. The metal plate can also reflect and block heat transfer from the outside of the radar spraying tooling 10. The thickness of the second heat insulation layer 123 is greater than the thickness of the top plate 122 to enhance the heat insulation performance of the second heat insulation layer 123, further reducing the temperature of the radar probe 13 during the spraying process and reducing damage to the electronic components inside the radar probe 13 in a high-temperature environment.

[0050] Furthermore, the thickness of the second insulation layer 123 is 5mm, and the thickness of the top plate 122 is 0.8mm.

[0051] Specifically, since the second heat insulation layer 123 is used to insulate heat transfer from top to bottom, and the heat insulation area of ​​the second heat insulation layer 123 to the radar probe 13 is smaller than that of the first heat insulation layer 112 to the radar probe 13, the thickness of the second heat insulation layer 123 can be set to be smaller than that of the first heat insulation layer 112 to reduce the space occupied by the radar spraying fixture 10. In this embodiment, by setting the thickness of the second heat insulation layer 123 to 5mm and the thickness of the top plate 122 to 0.8mm, the thickness ratio between the second heat insulation layer 123 and the top plate 122 is moderate, which can achieve a good heat insulation effect through the second heat insulation layer 123 while providing sufficient mechanical strength to the top plate 122.

[0052] In one embodiment, please refer to Figure 7-9 , Figure 7 yes Figure 3 An enlarged diagram of part C in the middle. Figure 8 This is a schematic diagram of the structure of the first embodiment of the radar probe provided in this application. Figure 9 This is a structural schematic diagram of the second embodiment of the radar probe provided in this application. Figure 7-9 As shown, the radar probe 13 also includes at least one first positioning part 133 and a main body part 131. The main body part 131 has a first side surface 131b, which is disposed around the first surface 131a. The first positioning part 133 is disposed on the first side surface 131b. The groove 114 includes at least one first slot 115, which is disposed corresponding to the first positioning part 133.

[0053] Specifically, the main body 131 of the radar probe 13 houses radar-related electronic components, including but not limited to antenna and vibrator systems, transmitters, and receivers. When the radar probe 13 is installed in a vehicle, the upper surface of the main body 131 needs to be exposed to ensure the radar signal transmission effect. Therefore, in this embodiment, the upper surface of the main body 131 is defined as the first surface 131a, and the first side surface 131b surrounding the first surface 131a is accommodated in the groove 114. The opening 121 on the cover plate 12 is used to expose the first surface 131a of the main body 131.

[0054] The first positioning part 133 of the radar probe 13 is a protruding part disposed on the first side 131b. The first positioning part 133 is used to snap-fit ​​with the snap-fit ​​part on the vehicle mounting position to realize the installation of the radar probe 13. The groove 114 on the base 11 in this embodiment includes a groove 114 body and a first slot 115. The first slot 115 communicates with the groove 114 body. The size of the first slot 115 corresponds to the size of the first positioning part 133, so that when the radar probe 13 is placed in the groove 114, the first positioning part 133 of the radar probe 13 can be accurately placed into the first slot 115, ensuring the accuracy of the radar probe 13 when installed on the base 11.

[0055] Optionally, the radar probe 13 includes two first positioning parts 133, which are symmetrically distributed around the main body 131.

[0056] Specifically, to ensure the installation stability of the radar probe 13, the radar probe 13 includes a first positioning part 133 and a second first positioning part 133. The first and second first positioning parts 133 are symmetrically distributed around the main body 131 in the circumferential direction. For example, the main body 131 is circular, and the first and second first positioning parts 133 are respectively distributed on both sides in the diameter direction. The radar probe 13 includes multiple first positioning parts 133, which can be arranged around the main body 131 in a circular trajectory. In this case, the number and position of the corresponding first slots 115 correspond to the first positioning parts 133, and will not be described further here.

[0057] In one embodiment, the radar probe 13 further includes a main body 131 and a wiring harness interface. The main body 131 has a second side surface 132b, which is disposed around the second surface 132a. The wiring harness interface is disposed on the second side surface 132b, and a groove 114 is used to accommodate the radar probe 13 and shield the wiring harness interface through the side wall.

[0058] Specifically, the main body 131 and the wiring section 132 are interconnected. The main body 131 houses radar components, such as an antenna and vibrator system, a transmitter, and a receiver. The wiring section 132 houses a wiring harness for connecting and communicating with external devices. The upper surface of the main body 131 is a first surface 131a, and the side surface of the main body 131 is a first side surface 131b. The upper surface of the wiring section 132 is a second surface 132a, the lower surface of the wiring section 132 is a third surface 132c, and the side surface of the wiring section 132 is a second side surface 132b. The wiring harness interface is connected to the wiring harness of the wiring section 132 and is located on the second side surface 132b. When the radar probe 13 is placed in the groove 114, the sidewall of the groove 114 seals the wiring harness interface on the second side surface 132b to prevent paint mist from entering the interface during the painting process. This reduces or avoids poor contact problems when the radar probe 13 communicates with external devices, further improving the reliability of the radar probe 13.

[0059] Optionally, the radar probe 13 further includes a second positioning part 134 and a wiring part 132. The second positioning part 134 is disposed on the third surface 132c of the wiring part 132. The radar probe 13 is placed in the groove 114. The groove 114 further includes a second slot 116, which is correspondingly disposed with the second positioning part 134.

[0060] Specifically, the upper surface of the wiring portion 132 is the second surface 132a, and the lower surface is the third surface 132c. The radar probe 13 may have two second positioning portions 134: the first second positioning portion 134 is located on the second surface 132a, and the second second positioning portion 134 is located on the third surface 132c, i.e., the two second positioning portions 134 are respectively located on the upper and lower surfaces of the wiring portion 132. When the wiring harness interface interacts with external devices for data exchange or signal coordination, the second positioning portion 134 is used to mate with the notch / groove of the docking component of the external device to achieve insertion positioning and ensure consistency of the insertion direction.

[0061] When the radar probe 13 is placed in the groove 114, the third surface 132c of the wiring part 132 contacts the bottom of the groove 114. A second slot 116 is provided at the position corresponding to the second positioning part 134 on the third surface 132c of the groove 114, and the second slot 116 is connected to the main body space of the groove 114. The size of the second slot 116 corresponds to the size of the protruding part of the second positioning part 134, so that when the radar probe 13 is placed in the groove 114, the second positioning part 134 can be accurately placed into the second slot 116, ensuring the accuracy of the radar probe 13 when it is installed on the base 11.

[0062] In one embodiment, the base 11 further includes a side plate 113, a bottom plate 111, and a first heat insulation layer 112. The side plate 113 is circumferentially disposed on the bottom plate 111, and the first heat insulation layer 112 is disposed on the bottom plate 111. The height of the side plate 113 is greater than or equal to the sum of the thickness of the bottom plate 111 and the thickness of the first heat insulation layer 112.

[0063] Specifically, the side plates 113 of the base 11 are circumferentially disposed on the base plate 111. The side plates 113 can be respectively disposed on each edge of the base plate 111, so that the side plates 113 surrounding the base plate 111 form a box space, and the first heat insulation layer 112 can be placed in the box space. The height of the side plates 113 is greater than or equal to the sum of the thickness of the base plate 111 and the thickness of the first heat insulation layer 112. When the radar probe 13 is placed in the groove 114, the part of the radar probe 13 exposed in the groove 114 is still located in the box space, so as to provide support and protection for the radar probe 13.

[0065] Specifically, the radar painting fixture 10, with its 56 grooves 114 and 56 openings 121, can simultaneously accommodate 56 radar probes 13 to be painted, enabling a single painting operation of a large number of radar probes 13, thus improving painting efficiency. Furthermore, since all 56 grooves 114 are located on the base 11 and all 56 openings 121 are located on the cover plate 12, it ensures that the exposed first surface 131a of all radar probes 13 is on the same plane, improving the quality and color consistency of subsequent painting.

[0066] This application also proposes a radar spraying system, including a radar spraying fixture 10 and a spraying device as described in any of the above embodiments, wherein the radar spraying fixture 10 is used to carry a plurality of radar probes 13.

[0067] The spraying equipment is located on one side of the radar spraying fixture 10. The radar spraying fixture 10 includes a cover plate 12. The cover plate 12 exposes the first surface 131a of the radar probe 13 through the opening 121. The spraying equipment is used to spray paint on the first surface 131a of several radar probes 13.

[0068] Specifically, the painting equipment can be positioned above the radar painting fixture 10 for painting. This painting equipment can be, but is not limited to, a paint gun, an automatic painting machine, an electrostatic painting machine, an airless painting machine, or a self-spraying paint can. In possible implementations, the radar painting fixture 10 can be placed on a fixed base, and the painting equipment can be fixed to a support to ensure uniform painting angle and distance; alternatively, multiple radar painting fixtures 10 can be placed on a conveyor belt, and the painting equipment can automatically paint multiple radar painting fixtures 10 on the conveyor belt to improve painting efficiency.

[0069] Optionally, the radar coating system also includes a mounting base, on which a third positioning part is provided; at least one positioning hole may be provided on the base plate 111 of the radar coating fixture 10, and the third positioning part is provided in correspondence with the positioning hole to position the base 11 of the radar coating fixture 10 on the mounting base.
