Description

Technical Field

[0001] This application relates to the field of vehicle-mounted camera modules, and more particularly to a connection structure for a vehicle-mounted camera module and a vehicle-mounted camera module. Background Technology

[0002] In-vehicle camera modules are key components of automotive intelligence, often referred to as the "eyes" of a car. They integrate core components such as optical lenses, image sensors, image signal processors (ISPs), serializers, and connectors to achieve high-precision perception of the vehicle's surroundings. Within these modules, FAKRA (Fachkreis Automobil-Rundfunk-Anschluss, the Automotive Radio Connector Group) plays a crucial role in transmitting radio frequency and video signals, ensuring high-speed and stable signal transmission between the camera and the vehicle's electronic systems.

[0003] FAKRA connectors are coaxial signal transmission connectors widely used in automotive electronics for transmitting radio frequency and video signals. Their structure typically includes a metal housing, a plastic base, a plastic ferrule, and metal terminals, with the metal housing providing shielding and protection.

[0004] With the rapid development of the automotive industry, in-vehicle camera application technology is becoming increasingly mature, and cars are equipped with cameras as an advanced driver assistance system. Camera pixels and power consumption are rising, making the use of metal materials for camera housings a trend for heat dissipation. However, existing integrated metal lower housings with connectors, such as those from FAKRA, have relatively high processing costs (e.g., ...). Figure 8 In addition, another type of FARKA split-type locking screw and sealing ring structure is commonly found in the industry (such as...). Figure 9 Separate locking screws are also prone to loosening or sealing failure, posing a quality hazard.

[0005] Therefore, a new type of vehicle-mounted camera module connection structure is needed to overcome the problems existing in the current technology. Utility Model Content

[0045] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0046] In the description of this application, it should be noted that the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., which indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of this application.

[0047] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0048] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0049] In this application, the X-axis and Z-axis represent the horizontal and vertical directions, respectively, and the X-axis and Z-axis are perpendicular to each other.

[0050] A connection structure for vehicle-mounted camera modules, such as Figures 1-7 As shown, the connector includes a connector core 2, a connector housing 1, and an outer shell 3. The connector housing 1 is connected to the outer shell 3. The connector core 2 is disposed within the outer shell 3 and extends into the connector housing 1. The connector housing 1 includes a mounting portion 11, and the outer shell 3 includes a support platform 31 and a solder groove 32. At least a portion of the mounting portion 11 is disposed on the support platform 31. The solder groove 32 is disposed above the support platform 31 and is located on the periphery of the mounting portion 11. The solder groove 32 is adapted to accommodate solder 320 to fix the mounting portion 11 and the outer shell 3, that is, the solder 320 after melting and solidification can seal the connector housing 1 and the outer shell 3 circumferentially.

[0051] It should be understood that, compared to adhesive bonding, this embodiment uses welding to seal the connection between the mounting part 11 and the housing 3, thereby improving the connection reliability and reducing the risk of the housing 3 shifting or loosening relative to the connector housing 1 under continuous vehicle vibration or collision impact.

[0052] Furthermore, the mounting part 11 includes a first bottom surface 112 and an outer surface 111. The solder groove 32 is disposed above the misaligned support platform 31 and opposite to the outer surface 111. The solder 320 in the solder groove 32 can fully contact the outer surface 111 of the mounting part 11 to enhance the connection strength between the connector housing 1 and the outer shell 3 and improve the overall stability of the connection structure.

[0053] Furthermore, the support platform 31 includes a first support surface 311 opposite to the first bottom surface 112 and a first side surface 312 opposite to the outer side surface 111. At least a portion of the first bottom surface 112 of the mounting portion 11 is supported by the first support surface 311, preventing molten solder 320 from seeping out from the first bottom surface 112 of the mounting portion 11. The solder tank 32 includes a second bottom surface 322, a second side surface 323, and a first guide surface 321 that extends obliquely downward from the second bottom surface 322 to the first side surface 312. The first guide surface 321 is adapted to guide the solder 320 to flow to the connection between the outer side surface 111 and the first side surface 312, further increasing the welding area between the connector housing 1 and the outer shell 3 and improving the reliability of the connection structure. That is, the second bottom surface 322, the second side surface 323, and the first guide surface 321 together circumferentially surround the outer side surface 111 to form a solder 320 receiving area.

[0054] It is worth mentioning that the solder 320 can be placed in a complete circle in the solder bath 32, or it can be placed in segments in the solder bath 32; the surface of the solder 320 after melting and solidification can be raised, recessed, or flat; this application does not impose specific limitations in this regard. Furthermore, the welding method includes, but is not limited to, radiant heating, convection heating, magnetic induction heating, and laser heating; this application does not impose specific limitations on the composition of the solder 320 or the welding method.

[0055] Compared to the prior art where the connector housing 1a and lower housing 3a are connected by screws 4a, which requires the screws 4a to be concealed within the connector housing 1a and lower housing 3a, and the overall volume of the connector increases along the Z-axis, this application uses solder 320 molten in solder groove 32 that is offset from the support platform 31 to fix the connector housing 1 and lower housing 3. This also significantly reduces the overall size of the connection structure along the Z-axis, which is beneficial for reducing production costs.

[0056] In some embodiments, such as Figure 2As shown, a gap 4 connecting the first side surface 312 and the outer side surface 111 is provided between them, which is a solder groove 32. The included angle between the first bottom surface 112 and the outer side surface 111 of the mounting part 11 is set as a chamfer, so that the gap 4 and the chamfer continue to communicate. That is, the solder 320 can continuously flow into the gap 4 and the chamfer under the guidance of the first guide surface 321, thereby further increasing the welding area between the connector housing 1 and the outer shell 3 and improving the overall reliability of the connection structure. It should be understood that along the X-axis direction, the width of the gap 4 is smaller than the width of the solder groove 32. That is, the radial distance between the first side surface 312 and the outer side surface 111 of the support platform 31 is smaller than the radial distance between the second side surface 323 and the outer side surface 111 of the solder groove 32, so that the solder 320 can slowly flow into the gap 4 and the chamfer. The optimized distribution of the solder 320 can reduce welding defects, such as voids and cracks, and improve the welding quality.

[0057] It is worth mentioning that the radial distance between the outer side 111 of the mounting part 11 and the second side 323 of the solder groove 32 is relatively large, which facilitates the easier insertion of solder 320, thereby reducing the difficulty of filling solder 320 and improving the efficiency of soldering the connector housing 1 and the outer shell 3. On the other hand, the radial distance between the outer side 111 of the mounting part 11 and the first side 312 of the support platform 31 is small, that is, the radial width of the gap 4 is small, thereby reducing the amount of solder 320 required to fill the gap 4 and reducing material costs.

[0058] In some embodiments, such as Figure 3 As shown, the mounting part 11 includes a first protrusion 113, the bottom surface of the first protrusion 113 is the first region 1121 of the first bottom surface 112, the first protrusion 113 also includes an outer side surface 111 extending upward from the edge of its bottom surface, a second guide surface 1132 extending obliquely upward from the outer side surface 111, and a first plane 1131 extending horizontally inward from the second guide surface 1132. The first region 1121 and the second region 1122 of the first bottom surface 112 are both located on the first support surface 311 of the support platform 31, that is, the first bottom surface 112 of the mounting part 11 is entirely located on the first support surface 311 of the support platform 31. The radial contact area between the mounting part 11 and the support platform 31 is widened, making the bearing relationship between the connector housing 1 and the outer shell 3 more stable.

[0059] Furthermore, the first plane 1131 of the first protrusion 113 is flush with the second bottom surface 322 of the solder groove 32, the second guide surface 1132 is opposite to the first guide surface 321 of the solder groove 32, the outer side surface 111 is opposite to the first side surface 312 of the support platform 31, and there is a gap 4 between the outer side surface 111 and the first side surface 312 suitable for accommodating solder 320. Specifically, the first plane 1131, the second bottom surface 322, the second guide surface 1132, the first guide surface 321, and the second side surface 323 surround the connector housing 1 in the circumferential direction to form a solder groove 32 for receiving solder 320. The bottom surface of the solder groove 32 continues to communicate with the gap 4 below, thereby forming a solder 320 accommodating area with a funnel-shaped symmetrical cross section. This can play a certain buffering role when the solder 320 is filled, thereby ensuring that the solder 320 can be filled evenly and improving the welding quality.

[0060] It is worth mentioning that by aligning the second guide surface 1132 with the first guide surface 321 of the solder bath 32, and aligning the outer side surface 111 with the first side surface 312, the cross-section of the molten and solidified solder 320 can be made symmetrical, such as... Figure 3 As shown, this helps to provide a uniform load transfer path to the molten and solidified solder 320, thereby optimizing stress distribution, reducing stress concentration, and improving the structural strength and welding reliability of the weld between the connector housing 1 and the outer shell 3.

[0061] In some embodiments, such as Figure 4 As shown, the mounting portion 11 also includes a second protrusion 114 extending downward along the second region 1122 of the first bottom surface 112 of the mounting portion 11. The second protrusion 114 includes a third bottom surface 1141 and a first outer surface 1142. The third bottom surface 1141 is flush with the bottom of the support platform 31, and the first outer surface 1142 is opposite to the support platform 31. The bottom surface of the first protrusion 113, i.e. the first region 1121, is located on the first support surface 311 of the support platform 31. The first protrusion 113 has an expansion groove 1135 that is recessed inward in a circumferential direction. Specifically, the outer surface 111 of the first protrusion 113 is recessed inward in a circumferential direction to form the expansion groove 1135.

[0062] It should be understood that the expansion groove 1135 is opposite to the first side 312 of the support platform 31. The expansion groove 1135 is recessed into the inner side of the first protrusion 113, which increases the area of ​​the outer side 111 of the first protrusion 113 that can contact the solder 320. That is, the gap 4 between the outer side 111 and the first side 312 can be filled with more solder 320, thereby further strengthening the stability of the connection between the connector housing 1 and the outer shell 3.

[0063] It is worth mentioning that the cross-sectional shape of the expansion slot 1135 can be as follows: Figure 4The triangle shown can also be a semicircle, trapezoid, rectangle, or other shapes; this application does not impose specific limitations on this. Furthermore, multiple expansion grooves 1135 can be provided on the first protrusion 113. In some embodiments, the outer surface 111 of the first protrusion 113 is recessed into the interior of the first protrusion 113 to form continuous expansion grooves 1135, which helps to improve the tensile strength and shear strength of the overall connection structure, thereby improving the reliability and durability of the connection structure.

[0064] In other embodiments, the first side surface 312 of the support platform 31 opposite to the first protrusion 113 may also be recessed into the interior of the support platform 31 to form one or more expansion grooves 1135, further increasing the contact area between the outer side surface 111 of the first protrusion 113 and the first side surface 312 and the solder 320, thereby more firmly connecting the connector housing 1 and the outer shell 3, and enhancing the mechanical strength and durability of the connection structure.

[0065] In some embodiments, such as Figure 5 As shown, the housing 3 also includes a retaining member 33, which is connected to the housing 3 circumferentially and extends away from the connector housing 1 along the Z-axis. This retaining member 33 helps prevent external physical impacts and harmful substances such as dust and liquids from entering the connector housing 1, thereby protecting the internal components of the connection structure from damage. It is worth noting that the housing 3 may also include other structures for connection, positioning, and installation; this application does not impose specific limitations on this.

[0066] In some embodiments, such as Figure 6 As shown, the third bottom surface 1141 of the second protrusion 114 extends outward and widens along the X-axis direction, and the third bottom surface 1141 is flush with the bottom of the housing 3. The second outer side surface 1142 of the second protrusion 114 is opposite to the support platform 31. The support platform 31 supports the first protrusion 113 above. The first protrusion 113 includes an outer side surface 111 and a first plane 1131 extending horizontally inward from the outer side surface 111. Further, the cross-section of the first protrusion 113 extends upward and widens along the Z-axis direction. Further, since the top of the housing 3 is flush with the first plane 1131 of the first protrusion 113, the depth of the solder groove 32 between the first protrusion 113 and the housing 3 is increased, and the amount of solder 320 that can be placed is increased, further strengthening the circumferential sealing strength of the connector housing 1 and the housing 3, and improving the quality of the connection structure. It is understandable that by appropriately increasing the bottom of the connector housing 1, the mounting part 11 can be inserted into the outer shell 3 from the outside and then soldered. After the increase, the top view shape of the solder groove 32 can be circular, square, or irregular, etc. That is, when viewed from below along the XY plane, the top view shape of the solder groove 32 can be circular, square, or irregular, etc.

[0067] It is worth mentioning that the distance between the outer side 111 and the second outer side 1142 is relatively wide, that is, the first support surface 311 of the support platform 31 is relatively wide, which helps to prevent the solder 320 from seeping out between the support platform 31 and the first protrusion 113 when it melts.

[0068] In some embodiments, such as Figure 7 As shown, the connector housing 1 is inserted into the outer shell 3 from the inside and then soldered. This application does not impose specific limitations on this process. In this embodiment, the support platform 31 on the outer shell 3 is connected in the opposite direction to the first protrusion 113. The support platform 31 is embedded between the outer side surface 111 of the first protrusion 113 and the first plane 1131. Solder 320 is placed in the solder tank 32 and injected into the gap 4 along the first guide surface 321 so that the connector housing 1 and the outer shell 3 are securely connected.

[0069] It is worth mentioning that the solder 320 can be placed in a complete circle in the solder bath 32, or it can be placed in segments in the solder bath 32; the surface of the solder 320 after melting and solidification can be raised, recessed, or flat; this application does not impose specific limitations in this regard. Furthermore, the welding method includes, but is not limited to, radiant heating, convection heating, magnetic induction heating, and laser heating; this application does not impose specific limitations on the composition of the solder 320 or the welding method.

[0070] In some embodiments, the connector housing 1 is made of metal, including but not limited to aluminum alloy, copper, stainless steel, or magnesium alloy; the outer shell 3 is made of metal, including but not limited to aluminum alloy, stainless steel, or tinplate; and the solder 320 is including but not limited to aluminum alloy, copper, stainless steel, or magnesium alloy. The metals used to manufacture the connector housing 1, outer shell 3, and solder 320 can be the same or different. Furthermore, to improve soldering reliability or reduce soldering difficulty, a plating layer can be provided on the surface of the connector housing 1 or outer shell 3; this application does not impose specific limitations on this.

[0071] This application provides a solder groove 32 between the connector housing 1 and the outer shell 3, using the solder cured in the solder groove 32 to tightly connect the connector housing 1 and the outer shell 3 together. Compared to existing technologies, this method... Figure 8 The FAKRA connector shown includes a connector housing 1a, a connector core 2a, and a lower shell 3a. The connector housing 1a and the lower shell 3a are integrally connected, resulting in excessively high manufacturing costs. In this application, the connector housing 1 and the lower shell 3 can be designed, modified, or iterated separately, and then assembled by subsequent soldering. This allows the same connector housing 1 to be adapted to different shells 3, or the same shell 3 to be matched with different connector housings 1, which is beneficial to improving the iterability of the connection structure, shortening the development time, and reducing the development cost.

[0072] Furthermore, compared to Figure 9As shown, in the prior art, the FAKRA connector uses a screw 4a to connect the connector housing 1a and the lower housing 3a, and a sealing ring 5a to prevent external impurities from entering the connector housing 1a. However, if the screw loosens, the connection between the connector housing 1a and the lower housing 3a can easily become unstable, affecting the reliability of signal transmission. Furthermore, loosening of the screw 4a may also increase the gap between the connector housing 1a and the lower housing 3a, affecting the sealing effect of the sealing ring 5a and increasing the risk of external impurities entering the connector. In contrast, this application uses a solder groove 32 to tightly bond the connector housing 1 and the lower housing 3a with solder 320, forming a stable connection structure. This eliminates the need for additional fasteners such as screws and rivets, reducing the number of parts and assembly steps, and facilitating automated assembly of the connector housing 1 and the lower housing 3, thereby further reducing the production cost of the connector.

[0073] Furthermore, this application also provides an in-vehicle camera module, including: a lens; a connection structure for the in-vehicle camera module as described above; a circuit board, the side of the circuit board facing away from the lens being connected to the connection structure for the in-vehicle camera module, the connection structure being used to transmit image information captured by the lens to the vehicle system.

[0074] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection claimed by this application is defined by the appended claims and their equivalents.
