[0002] On-board cameras are devices used to provide the images required during vehicle driving.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0069] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0070] See also Figures 1 to 3 , a vehicle-mounted camera provided by an embodiment of the utility model includes a housing 100, a lens structure 200, a circuit board 400 and a rear cover 500, wherein the housing 100 has a front mounting opening 110 and a rear mounting opening 120, the front mounting opening 110 is arranged at the front end portion of the housing 100, and the rear mounting opening 120 is arranged at the rear end portion of the housing 100, and the openings of the two are arranged in opposite directions; the lens structure 200 is assembled and connected to the front mounting opening 110, and a power-carrying wire 300 is arranged at the tail of the lens structure 200; the circuit board 400 is arranged on the inner side of the housing 100, and a wire passing hole 410 is opened on the circuit board 400, and the power-carrying wire 300 is passed through the wire passing hole 410 and connected to a side of the circuit board 400 away from the lens structure 200; the rear cover 500 is assembled and connected to the rear mounting opening 120 of the housing 100.

[0071] Specifically, during the assembly process of the vehicle-mounted camera, the circuit board 400 is assembled on the inner side of the housing 100. When the lens structure 200 is assembled on the housing 100, the power-carrying wire 300 is passed through the wire hole 410 and connected to the side of the circuit board 400 away from the lens structure 200. It can be understood that the power-carrying wire 300 is passed through the wire hole 410 of the circuit board 400 to connect to the side of the circuit board 400 away from the lens structure 200. In this way, there is no need to reserve a wire gap between the inner wall of the housing 100 and the edge of the circuit board 400, and the size of the housing 100 is effectively reduced, thereby reducing the overall size of the vehicle-mounted camera, which is more flexible in application to vehicles.

[0072] Moreover, when the vehicle-mounted camera is used in a vehicle, the vehicle is usually electrically connected to the lens structure 200 through the side of the circuit board 400 away from the lens structure 200. In the present application, the power wire 300 is connected to the side of the circuit board 400 away from the lens structure 200 through the wire hole 410, instead of connecting the power wire 300 to the side of the circuit board 400 close to the lens structure 200. In this way, the circuit board 400 only needs to be provided with a circuit on the same side, which can reduce the difficulty of manufacturing the circuit board 400. Of course, according to actual needs, the present application scheme does not limit the selected circuit board 400 to have a circuit on only one side, and can also have circuits on both sides.

[0073] In addition, the power conductor 300 is connected to the side of the circuit board 400 away from the lens structure 200. After the housing 100, the circuit board 400 and the lens structure 200 are assembled, the staff can easily connect the power conductor 300 to the circuit board 400 through the rear installation port 120 of the housing 100.

[0074] In some embodiments, the power wire 300 is configured to be able to maintain a set extension state relative to the lens structure 200, so as to pass through the wire hole 410 when the lens structure 200 is assembled with the housing 100. Specifically, when the vehicle-mounted camera is assembled, the circuit board 400 is assembled and connected to the housing 100, and when the lens structure 200 is assembled on the housing 100, the power wire 300 is set to the extension state, for example, the power wire 300 is straightened so that the power wire 300 is maintained in a straight extension state relative to the lens structure 200. In this way, when the lens structure 200 is assembled on the housing 100, the power wire 300 is just passed through the wire hole 410, so that the lens structure 200 is easily installed on the housing 100, ensuring the assembly efficiency of the vehicle-mounted camera.

[0075] Among them, setting the extended state refers to the state in which the power conductor 300 can pass through the wire hole 410 when the lens structure 200 is assembled with the housing 100. For example, the power conductor 300 is kept straight relative to the lens structure 300, or the power conductor 300 is kept slightly tilted relative to the lens structure 300. The power conductor 300 can pass through the wire hole 410 when the lens structure 200 and the housing 100 are assembled. Therefore, setting the extended state does not limit a specific extended state. The extended state that the power conductor 300 needs to maintain can be adjusted according to the size of the wire hole 410 and the position in the cross section. In addition, the end of the power conductor 300 away from the lens structure 300 may not be in a fixed state. When the lens structure 200 and the housing 100 are assembled, the power conductor 300 also passes through the wire hole. Therefore, when the power conductor 300 is maintained in the set extended state, it is not limited that the end of the power conductor 300 (the bending section described below) is also in a fixed state. It is set according to actual needs and will be described in detail later.

[0076] In some embodiments, the power conductor 300 is configured to be set with a preset hardness so that the power conductor 300 is maintained in a set extension state relative to the lens structure 200 when the lens structure 200 is assembled. It can be understood that the power conductor 300 of the lens structure 200 is generally a flexible conductor. In the present application, the power conductor 300 of the lens structure 200 can be a conductor with a certain hardness, for example, the power conductor 300 is configured to be set with a preset hardness so that the power conductor 300 can be maintained in a set extension state relative to the lens structure 200, for example, the battery core of the power conductor 300 has a certain hardness, and in the absence of external force, the power conductor 300 can be maintained in a set extension state; or, the insulating layer 320 of the power conductor 300 has a certain hardness, so that the power conductor 300 can be maintained in a set extension state relative to the lens structure 200.

[0077] In one possible embodiment, referring to Figure 2 and Figure 3 The power-carrying wire 300 includes a conductive core 310, which is configured to be set with a first set hardness so as to be able to maintain a set extended state and pass through the wire hole 410, and can be bent to be connected to a side of the circuit board 400 away from the lens structure 200.

[0078] The conductive core 310 is configured to be set with a first set hardness, so that the current-carrying wire 300 has a certain hardness and the conductive core 310 can maintain a set extension state; and the conductive core 310 can also be bent to connect with the circuit board 400.

[0079] For example, the conductive core 310 is a copper wire, and the cross-sectional dimension of the copper wire has a certain size. Accordingly, the copper wire has a certain hardness, that is, it meets the first set hardness requirement. In the absence of external force, the power conductor 300 can remain in a straight state. Therefore, when the lens structure 200 is assembled on the housing 100, the power conductor 300 can remain inserted into the wire hole 410. In addition, after the power conductor 300 passes through the circuit board 400, the end of the power conductor 300 can also be bent so that it can be connected to the side of the circuit board 400 away from the lens structure 200.

[0080] In a second possible embodiment, the current-carrying wire 300 includes a conductive core 310 and an insulating layer 320, wherein the conductive core 310 includes a first extension section 311 and a first bending section 312 connected to each other, one end of the first extension section 311 is connected to the lens structure 200, and the first bending section 312 is connected to the other end of the first extension section 311, wherein the first extension section 311 is used to pass through the wire hole 410 of the circuit board 400, and the first bending section 312 can be bent to connect to a side of the circuit board 400 away from the lens structure 200. The insulating layer 320 is configured to be set with a second set hardness, for example, the insulating layer 320 is a plastic layer with a certain hardness, and the insulating layer 320 is sleeved on the outer side of the first extension section 311, so that the first extension section 311 can be maintained in a set extension state relative to the lens structure 200.

[0081] It is understandable that when the lens structure 200 is assembled in the housing 100, the insulating layer 320 is sleeved on the outside of the first extension section 311. In this way, the first extension section 311 can maintain a set extension state relative to the lens structure 200. In this way, when the lens structure 200 is assembled in the housing 100, the first extension section 311 just passes through the wire hole 410 of the circuit board 400, so as to facilitate the first bending section 312 to be connected to the side of the circuit board 400 away from the lens structure 200. It should be noted that since the insulating layer 320 is not wrapped around the outside of the first bending section 312, the insulating layer 320 will not interfere with the bending of the first bending section 312, so that the first bending section 312 can be connected to the side of the circuit board 400 away from the lens structure 200.

[0082] Of course, the insulating layer 320 can also be wrapped around the outside of the first bending section 312. After the power-carrying wire 300 passes through the wire hole 410 of the circuit board 400, the staff can remove the insulating layer 320 located outside the first bending section 312, thereby exposing the first bending section 312. At this time, without the interference of the insulating layer 320, the staff can bend the first bending section 312 to the side of the circuit board 400 away from the lens structure 200, thereby electrically connecting with the circuit board 400.

[0083] In a third possible embodiment, the vehicle-mounted camera further includes a reinforcement. Specifically, the power-carrying wire 300 may be a flexible wire, and the power-carrying wire 300 includes a second extension section and a second bending section (not shown in the figure) connected to each other, one end of the second extension section is connected to the lens structure 200, and the second bending section is connected to the other end of the second extension section, wherein the second extension section is passed through the wire hole 410 of the circuit board 400, and the second bending section is connected to the side of the circuit board 400 away from the lens structure 200. The reinforcement can be arranged on the power-carrying wire 300, more specifically, the reinforcement is at least arranged on the second extension section, the reinforcement can be arranged on the inner side of the power-carrying wire 300, and can also be arranged on the outer side of the power-carrying wire 300, and the specific structure of the reinforcement is not limited. In this way, the reinforcement can at least make the second extension section have a certain hardness, and the second extension section can remain in a straight state relative to the lens structure 200.

[0084] Specifically, before the lens structure 200 is assembled to the housing 100, the staff extends the second extension section in a straight line relative to the lens structure 200, and sets a reinforcement on the second extension section, so that the reinforcement keeps the second extension section in a set extension state. With this arrangement, when the lens structure 200 is assembled to the housing 100, the reinforcement frame keeps the second extension section in a set extension state, thereby ensuring that when the lens structure 200 is assembled to the housing 100, the second extension section can pass through the wire hole 410 of the circuit board 400, thereby facilitating the connection between the second bending section and the side of the circuit board 400 away from the lens structure 200.

[0085] Of course, the reinforcement piece can also be disposed on the outside of the second bending section. After the current conducting wire 300 passes through the wire hole 410 of the circuit board 400, the staff can remove the reinforcement piece on the second bending section. At this time, without the interference of the reinforcement piece, the staff can bend the second bending section to the side of the circuit board 400 away from the lens structure 200, so as to connect with the circuit board 400.

[0086] In a specific embodiment, the reinforcement member may be a sleeve, which may be a metal sleeve or a plastic sleeve, and requires a certain hardness, that is, a flexible sleeve cannot be selected. In application, in order to keep the second extension section of the power-carrying wire 300 in a set extension state, the reinforcement member is sleeved on the outside of the second extension section of the power-carrying wire 300, and of course, it can also be sleeved on the second bending section at the same time, so that the reinforcement member keeps the second extension section of the power-carrying wire 300 in a set extension state. It can be understood that the reinforcement member adopts a sleeve, and the reinforcement member can be conveniently assembled on the outside of the second extension section to keep the second extension section in a set extension state.

[0087] Instead of using the reinforcing member as a sleeve, in another possible embodiment, the reinforcing member is a fitting member, which may be a metal fitting member or a plastic fitting member, which requires a certain hardness, that is, a flexible fitting member cannot be selected. When used, in order to keep the second extension section of the current-carrying wire 300 in a set extension state, the reinforcing member is attached to the outer side of the second extension section of the current-carrying wire 300, and of course it can also be attached to the second bending section at the same time, so that the reinforcing member keeps the second extension section of the current-carrying wire 300 in a set extension state. Among them, in order to make the fitting member fixed to the surface of the second extension section, the fitting member can be fixed to the side wall of the second extension section by gluing, or it can be wrapped around the second extension section. Of course, the fitting member can also be fixed to the side wall of the second extension section in other ways to keep the second extension section in a set extension state, which are not listed one by one.

[0088] In other possible embodiments, the reinforcing member is a reinforcement layer attached to the surface of the second extension section, or is an elastic rod disposed inside or outside the current-carrying conductor 300 , which will not be described in detail.

[0089] In some embodiments, the reinforcement is detachably connected to the power-carrying wire 300. For example, the reinforcement is a sleeve sleeved on the power-carrying wire 300 or a fitting attached to the power-carrying wire 300. After the reinforcement is connected to the power-carrying wire 300, the reinforcement can be easily removed from the power-carrying wire 300. Specifically, after the lens structure 200 is assembled to the housing 100, the reinforcement can be retained on the power-carrying wire 300 or removed from the power-carrying wire 300, and the arrangement is performed according to actual needs. After the reinforcement is removed, the power-carrying wire 300 can be easily connected to the circuit board 400.

[0090] In some embodiments, the lens structure 200 is configured to be assembled with the housing 100 using an AA process. Specifically, when the lens structure 200 is installed on the housing 100, the power-carrying wire 300 can maintain a set extension state, and the power-carrying wire 300 can be directly passed through the wire hole 410 of the circuit board 400 when the lens structure 200 is assembled. As a result, the lens structure 200 can use a universal AA device to complete the assembly of the lens structure 200, thereby ensuring the production efficiency of the vehicle-mounted camera. In addition, when the lens structure 200 is assembled, the power-carrying wire 300 can maintain a set extension state, and a universal AA device can complete the assembly of the lens structure 200 on the housing 100, without the need to develop a new AA device to complete the assembly of the lens structure 200 on the housing 100, thereby saving costs.

[0091] Further, refer to Figure 3 and Figure 4The housing 100 is provided with a first assembly surface 130 arranged around the front mounting opening 110. For example, the first assembly surface 130 is an annular end surface arranged on the housing 100. The side of the lens structure 200 is provided with an annular boss, which forms a second assembly surface 210. The first assembly surface 130 and the second assembly surface 210 are connected by a UV curing adhesive 150. Specifically, during the assembly process of the lens structure 200, the dispensing device dispenses UV curing adhesive 150 on the first assembly surface 130 and / or the second assembly surface 210, and the lens structure 200 is assembled on the housing 100 by using an AA device. The first assembly surface 130 and the second assembly surface 210 are bonded by the UV curing adhesive 150. Then, the liquid UV curing adhesive 150 is irradiated with UV light, and the UV curing adhesive 150 is converted from a liquid state to a solid state. Thus, the UV curing adhesive 150 fixes the lens structure 200 on the housing 100 and maintains the sealing between the lens structure 200 and the housing 100.

[0092] It is understandable that the lens structure 200 is connected to the housing 100 by using UV curing adhesive 150, and when the AA device assembles the lens structure 200 to the housing 100, the lens structure 200 and the housing 100 are bonded, thereby further facilitating the assembly of the lens structure 200. In addition, the lens structure 200 is connected to the housing 100 by using UV curing adhesive 150, and the lens structure 200 and the housing 100 are equivalent to a floating connection, and the external adjustment mechanism can make slight adjustments to the lens structure 200.

[0093] Furthermore, a mounting boss 140 is provided on the inner side of the housing 100, and the mounting boss 140 is provided toward the rear mounting opening 120. When the circuit board 400 is installed, the circuit board 400 can be conveniently embedded into the inner side of the housing 100 through the rear mounting opening 120, and the corner of the circuit board 400 close to the lens structure 200 is attached to the mounting boss 140 and fixed to the mounting boss 140 by screws; at the same time, the end of the housing 100 away from the lens structure 200 is welded to the back cover 500. Of course, the circuit board 300 can also be fixed to the mounting boss 140 by soldering, UV glue, etc., which will not be described in detail.

[0094] It is understandable that in order to achieve relative adjustment between the circuit board 400 and the lens structure 200, the circuit board 400 is fixed to the housing 100 by UV glue. In this way, when the rear cover 500 is laser-welded with the housing 100, the high temperature generated is likely to affect the UV glue between the circuit board 400 and the housing 100, thereby affecting the connection of the circuit board 400. In the present application, the circuit board 400 is fixed to the inner side of the housing 100 by screws. In this way, when the rear cover 500 is laser-welded with the housing 100, the high temperature generated will not affect the connection of the circuit board 400. In addition, the connection position between the rear cover 500 and the housing 100 is relatively far from the UV curing glue 150 between the lens structure 200 and the housing 100, thereby effectively reducing the high temperature generated during welding from affecting the connection between the lens structure 200 and the housing 100.

[0095] Of course, the circuit board 400 may also be connected to the housing 400 by using UV glue, solder, etc., which is not specifically limited in this application.

[0096] In some embodiments, the wire hole 410 extends to the edge of the circuit board 400. Specifically, as stated above, the reinforcement member usually only fixes the second extension section of the current-carrying wire 300, and the second bent section can remain flexible to facilitate connection with the circuit board 400. In the present application, the wire hole 410 adopts the above-mentioned structural form, and a large enough space is reserved on the circuit board 400 for the second bent section to pass through the wire hole 410.

[0097] In order to facilitate the connection between the power-carrying wire 300 and the circuit board 400, in a possible embodiment, a first connector 430 is provided on the side of the circuit board 400 away from the lens structure 200, and a second connector is provided on the end of the power-carrying wire 300 away from the lens structure 200, and the first connector 430 is plugged and connected with the second connector, so as to realize the electrical connection between the lens structure 200 and the circuit board 400. It can be understood that in conventional technology, the power-carrying wire 300 is usually connected to the circuit board 400 by welding. In the present application, by setting the first connector 430 and the second connector, the second connector can be conveniently plugged into a connector 430, so that the power-carrying wire 300 can be conveniently connected to the side of the circuit board 400 away from the lens structure 200, thereby assembling the vehicle-mounted camera is more convenient.

[0098] In some embodiments, reference Figure 3 and Figure 4, a first power terminal 420 is provided at the center of the circuit board 400 near the rear cover 500, a second power terminal 510 is provided at the center of the rear cover 500, the first power terminal 420 is plug-connected with the second power terminal 510, and the second power terminal 510 is connected with the circuit board 400. When applied to a vehicle, the connection terminal on the vehicle is plug-connected with the outer end of the second power terminal 510, and the first power terminal 420 is plug-connected with the second power terminal 510, thereby the connection terminal on the vehicle is connected with the circuit board 400, so that the signal captured by the lens structure 200 can be obtained.

[0099] The present application discloses a method for preparing a vehicle-mounted camera. Figures 3 to 5 , applied to the above-mentioned vehicle-mounted camera, the preparation method includes:

[0100] S101 assembles and connects the prepared circuit board 400 to the housing 100 .

[0101] Among them, the circuit board 400 can be fixed to the inner side of the shell 100 by bolts, and can also be fixed to the inner side of the shell 100 by UV glue. One side of the circuit board 400 is set facing the rear installation port 120 of the shell 100, and the other side is set facing the front installation port 110 of the shell 100.

[0102] S102 applies glue to the first assembly surface 130 of the housing 100 and / or the second assembly surface 210 of the lens structure 200 .

[0103] The front end of the housing 100 forms an annular first assembly surface 130 around the front mounting opening 110, and the outer side of the lens structure 200 is provided with an annular boss, which is formed on the second assembly surface 210, and the first assembly surface 130 is matched. The glue dispensing device can dispense liquid glue on the first assembly surface 130 and / or the second assembly surface 210, and the glue can be the above-mentioned UV curing glue 150 or other glue.

[0104] S103 uses AA equipment to assemble the lens structure 200 to the front mounting port 110 of the housing 100, the power-carrying wire 300 is passed through the wire hole 410, and the first assembly surface 130 of the housing 100 is bonded to the second assembly surface 210 of the lens structure 200; wherein, the power-carrying wire 300 is maintained in a set extended state relative to the lens structure 200 when the lens structure 200 is assembled.

[0105] Among them, the power-carrying wire 300 of the lens structure 200 is usually a flexible wire. In the present application, the power-carrying wire 300 of the lens structure 200 can be a wire with a certain hardness, for example, the power-carrying wire 300 is configured to be set with a preset hardness, so that the power-carrying wire 300 can be kept in a set extension state relative to the lens structure 200, for example, the battery core of the power-carrying wire 300 has a certain hardness, and in the absence of external force, the power-carrying wire 300 can be kept in a set extension state; or, the insulating layer 320 of the power-carrying wire 300 has a certain hardness, so that the power-carrying wire 300 can be kept in a set extension state relative to the lens structure 200. Or other methods are used to keep the power-carrying wire 300 in a set extension state relative to the lens structure 200, which will be described in detail later.

[0106] Specifically, when the lens structure 200 is installed in the housing 100, the power-carrying wire 300 maintains a set extension state relative to the lens structure 200. Therefore, the power-carrying wire 300 can be directly passed through the wire hole 410 of the circuit board 400 when the lens structure 200 is installed. As a result, the lens structure 200 can use a universal AA device to complete the assembly of the lens structure 200, thereby ensuring the production efficiency of the vehicle-mounted camera. It can be understood that when the lens structure 200 is assembled with the housing 100, the power-carrying wire 300 can maintain a set extension state, and the universal AA device can complete the assembly of the lens structure 200 on the housing 100, without the need to develop a new AA device to complete the assembly of the lens structure 200 on the housing 100, saving costs.

[0107] In addition, during the assembly process of the lens structure 200, the glue dispensing device dispenses liquid UV curing glue 150 or other glue to the first assembly surface 130 and / or the second assembly surface 210, and the lens structure 200 is assembled on the housing 100 using the AA device, and the first assembly surface 130 and the second assembly surface 210 are bonded together by the UV curing glue 150. Then, the liquid UV curing glue 150 is irradiated with UV light, and the UV curing glue 150 is converted from a liquid state to a solid state, thereby fixing the lens structure 200 on the housing 100 with the UV curing glue 150, and maintaining the seal between the lens structure 200 and the housing 100.

[0108] S104 connects the power conducting wire 300 to a side of the circuit board 400 away from the lens structure 200 through the rear mounting port 120 .

[0109] Specifically, after the lens structure 200 is assembled in the housing 100, the end of the power-carrying wire 300 away from the lens structure 200 just passes through the wire hole 410 of the circuit board 400. At this time, the staff can bend the power-carrying wire 300 at this position to connect the power-carrying wire 300 to the side of the circuit board 400 away from the lens structure 200.

[0110] For example, a first connector 430 may be provided on one side of the circuit board 400 away from the lens structure 200, and a second connector may be provided on one end of the power wire 300 away from the lens structure 200. The first connector 430 is plug-connected with the second connector to connect the lens structure 200 with the circuit board 400.

[0111] S105 connects the prepared rear cover 500 to the rear installation opening 120 of the housing 100 .

[0112] Among them, the back cover 500 and the outer shell 100 can be fixedly connected by screws, welding, or snap-on connection, which is not described in detail in this application.

[0113] In summary, in steps S101 to 105, the vehicle camera adopts the above-mentioned assembly method, and the assembly of the vehicle camera is relatively convenient, especially when the housing 100 and the lens structure 200 are assembled, a general AA device can be used for assembly, thereby ensuring the production efficiency of the vehicle camera and reducing the cost.

[0114] In some embodiments, before the lens structure 200 is assembled to the front mounting opening 110 of the housing 100 using the AA device in step S103 , step A1 is included.

[0115] A1 keeps the current conducting wire 300 in a set extended state relative to the lens structure 200 .

[0116] Among them, step A1 is not limited to being completed after step S101 and step S102. Step A1 can also be completed before step S101 or step S102, and this application is not limited to this.

[0117] Specifically, before assembling the lens structure 200 to the housing 100 of the AA device, the staff straightens or otherwise extends the power wire 300, that is, adjusts the power wire 300 according to actual needs so that the power wire 300 can be in a set extended state relative to the lens structure 200.

[0118] In a further embodiment, step A1 keeps the powered conductive wire 300 in a set extended state relative to the lens structure 200, including step B1.

[0119] B1: The prepared reinforcement member is placed on the power-carrying wire 300 to keep the power-carrying wire 300 in a set extended state relative to the lens structure 200.

[0120] The reinforcing member is a sleeve sleeved on the outside of the current-carrying conductor 300; or, the reinforcing member is a fitting member fixed to the outside of the current-carrying conductor 300; or, the reinforcing member is a reinforcement layer attached to the surface of the current-carrying conductor 300, which has been described in detail above.

[0121] Specifically, the power-carrying wire 300 can be a flexible wire. The power-carrying wire 300 includes a second extension section and a second bending section connected to each other, one end of the second extension section is connected to the lens structure 200, and the second bending section is connected to the other end of the second extension section, wherein the second extension section is passed through the wire hole 410 of the circuit board 400, and the second bending section is connected to the side of the circuit board 400 away from the lens structure 200. Specific description. Before the lens structure 200 is assembled on the housing 100, the reinforcement is arranged on the outside of the second extension section, and can also be arranged on the outside of the second bending section at the same time, so that the reinforcement can make the second extension section have a certain hardness, and the second extension section can remain in a straight state relative to the lens structure 200, so that the housing 100 and the lens structure 200 can be assembled using a universal AA device.

[0122] In some embodiments, before step S104 of connecting the power conducting wire 300 to a side of the circuit board 400 away from the lens structure 200 through the rear mounting opening 120 , the preparation method further includes step C1 .

[0123] C1 removes the reinforcement outside the current carrying wire 300.

[0124] Specifically, after the lens structure 200 is assembled on the housing 100 and the power-carrying wire 300 passes through the wire hole 410, the reinforcement piece can be retained on the power-carrying wire 300, or the reinforcement piece can be removed from the power-carrying wire 300, and the reinforcement piece can be arranged according to actual needs. For example, the reinforcement piece is a sleeve sleeved on the power-carrying wire 300 or a bonding piece pasted on the power-carrying wire 300. After the reinforcement piece is connected to the power-carrying wire 300, the reinforcement piece can be conveniently removed from the power-carrying wire 300. And after the reinforcement piece is removed, the power-carrying wire 300 can be easily connected to the circuit board 400.

[0125] In some embodiments, the lens structure 200 is assembled to the front mounting port 110 of the housing 100 using an AA device in step S103, wherein the AA device includes a loading fixture and an execution terminal, including steps D1 to D3.

[0126] D1 lowers the height of the loading jig relative to the execution end, wherein the loading jig loads one of the housing 100 and the lens structure 300 , and the execution end grabs the other one.

[0127] In order to lower the height of the loading jig relative to the execution terminal, a lifting module may be provided at the bottom of the device jig, and the lifting module is used to lift and adjust the height of the loading jig.

[0128] In a specific application, after the circuit board 400 and the housing 100 are assembled, the housing 100 is loaded on the loading jig, and the height of the assembly jig is lowered relative to the execution end, thereby lowering the height of the housing 100 and the circuit board 400; at the same time, the execution end grabs the lens structure 200 and moves it to the top of the loading jig, that is, the top of the circuit board 400. It should be noted that the loading jig can be moved downward for a certain distance, and the energized wire 300 in the extended state can be moved to the top of the loading jig without interfering with the loading jig, so that the solution can be implemented.

[0129] D2 raises the height of the loading jig relative to the execution end so that the loading jig is within the stroke of the execution end.

[0130] D3 controls the execution end to move toward the loading fixture to assemble the lens structure 200 to the front installation port 110 of the housing 100 .

[0131] In steps D2 and D3, the lifting module raises the height of the loading jig, and the loading jig moves upward to within the movement range of the execution end; at the same time, the execution end is controlled to drive the lens structure 200 to move downward, and the power wire 300 passes downward through the wire hole 410, and the lens structure 200 is assembled on the front mounting port 110 of the housing 100.

[0132] It should be noted that in the general AA device, there is a specific height stroke between the loading fixture and the execution end. Therefore, if the power-carrying wire 300 is set to an extended state, the general AA device may not be applicable. In steps D1 and D2 of the present application, by lowering and lifting the height of the loading fixture relative to the execution end, and without adjusting the height stroke of the execution end, the distance between the loading fixture and the execution end can be adapted to the power-carrying wire 300 set to an extended state, so that the general AA device can also be applied to the assembly of the lens structure 200 and the housing 100, saving costs.

[0133] The present application also discloses a method for preparing a vehicle-mounted camera, referring to Figure 4 and Figure 6 , applied to the above-mentioned vehicle-mounted camera, the preparation method comprises:

[0134] S100 assembles and connects the prepared lens structure 200 to the housing 100 .

[0135] S200 is to apply glue to the third assembly surface of the housing 100 and / or the side surface of the lens structure 200 .

[0136] S300 uses AA equipment to assemble the circuit board 400 on the housing 100, the power-carrying wire 300 is passed through the wire hole 410, and the third assembly surface of the housing 100 is bonded to the side of the circuit board 400; wherein, the power-carrying wire 300 is maintained in a set extended state relative to the lens structure 200 when the circuit board 400 is assembled.

[0137] S400 connects the power conducting wire 300 to a side of the circuit board 400 away from the lens structure 200 through the rear mounting port 120 .

[0138] S500 connects the prepared rear cover 500 to the rear installation opening 120 of the housing 100 .

[0139] Specifically, when the circuit board 400 is installed in the housing 100, the power wire 300 maintains a set extension state relative to the lens structure 200. Therefore, the power wire 300 can be directly passed through the wire hole 410 of the circuit board 400 when the circuit board 400 is installed. As a result, the circuit board 400 can use a universal AA device to complete the assembly of the circuit board 400, thereby ensuring the production efficiency of the vehicle-mounted camera. It can be understood that when the circuit board 400 is assembled with the housing 100, the power wire 300 can maintain a set extension state, and the universal AA device can complete the assembly of the circuit board 400 on the housing 100, without the need to develop a new AA device to complete the assembly of the circuit board 400 on the housing 100, saving costs.

[0140] In addition, during the assembly process of the lens structure 200, the glue dispensing device dispenses liquid UV curing glue 150 or other glue on the third assembly surface and / or the side of the circuit board 400, and the circuit board 400 is assembled on the housing 100 using the AA device, and the circuit board 400 and the housing 100 are bonded together by the UV curing glue 150. Then, the liquid UV curing glue 150 is irradiated with UV light, and the UV curing glue 150 is converted from a liquid state to a solid state, thereby fixing the circuit board 400 on the housing 100 with the UV curing glue 150.

[0141] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
