The straight lines of the car body are parallel, so that the millimeter-wave radar can accurately detect obstacles ahead and provide safety warnings. Since the front bumper is generally arc-shaped, it is difficult for the millimeter-wave radar to directly realize the normal direction parallel to the direction of the vehicle body after installation, and it is necessary to adjust the millimeter-wave radar. The existing millimeter wave radar requires an external adjustment bracket during installation, the adjustment bracket is installed on the vehicle body, and then the millimeter wave radar is installed on the adjustment bracket, and the millimeter wave radar is at the best angular position by rotating the adjustment bracket. However, this adjustment structure has the problems of complex installation structure and large space occupation, which affects the overall aesthetics of the car.

相比现有技术，本发明的方案具有以下优点：Compared with the prior art, the solution of the present invention has the following advantages:

5.本发明涉及的车载距离探测装置中，容纳壳前端的安装端面上设置卡接槽，使发光源辅助校准装置能够更快地实现与车载距离探测装置的组装，由于车载距离探测装置通过转动容纳壳即可实现探测方向的校准，利用发光源辅助校准装置直接与容纳壳进行连接，方便快速调节，也提高了校准的精确性。5. In the vehicle-mounted distance detection device related to the present invention, the mounting end surface of the front end of the housing shell is provided with a clamping groove, so that the luminous source auxiliary calibration device can be assembled with the vehicle-mounted distance detection device more quickly, because the vehicle-mounted distance detection device rotates The accommodating shell can realize the calibration of the detection direction, and the luminous source auxiliary calibration device is directly connected with the accommodating shell, which is convenient for quick adjustment and also improves the accuracy of calibration.
6.本发明涉及的车载距离探测装置中，面盖可拆卸地连接于安装壳上，根据车身的喷漆颜色选择不同颜色的面盖与安装壳进行组装，由于毫米波雷达安装于车身上后仅面盖外露，可大大地提高毫米波雷达的隐蔽性，提升车身整体的美观性，而毫米波雷达除了面盖的其他部分结构均可规模化生产，生产成本大大降低。6. In the vehicle-mounted distance detection device related to the present invention, the face cover is detachably connected to the mounting shell, and different colors of the face cover and the mounting shell are selected according to the spray paint color of the vehicle body for assembly.

具体实施方式Detailed ways
下面详细描述本发明的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本发明，而不能解释为对本发明的限制。The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings, in which the same or similar reference numerals indicate the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the drawings are exemplary, and are only used to explain the present invention, but cannot be construed as limiting the present invention.
如图1至图4所示，本发明提供了一种车载电子设备，具体为一种车载距离探测装置1，在本实施例中，所述车载距离探测装置1为前方碰撞预警传感器，具体采用毫米波雷达，用于探测前方车辆或障碍物，为驾驶员提供安全预警。在其他实施例中，所述车载距离探测装置1还可以为倒车雷达或摄像装置。As shown in Figures 1 to 4, the present invention provides a vehicle-mounted electronic device, specifically a vehicle-mounted distance detection device 1. In this embodiment, the vehicle-mounted distance detection device 1 is a front collision warning sensor, which specifically adopts Millimeter-wave radar is used to detect vehicles or obstacles ahead and provide drivers with safety warnings. In other embodiments, the vehicle-mounted distance detection device 1 may also be a reversing radar or a camera device.
在本实施例中，所述车载距离探测装置1包括壳体11和装设于壳体11内的距离探测部件12，所述壳体11包括安装壳111和容纳壳112，所述安装壳111用于与车身安装固定，所述距离探测部件12安装固定于容纳壳112内且容纳壳112可转动地与安装壳111连接使距离探测部件12的距离探测朝向随容纳壳112的转动实现可调。In this embodiment, the vehicle-mounted distance detection device 1 includes a housing 11 and a distance detection component 12 installed in the housing 11. The housing 11 includes a mounting housing 111 and an accommodating housing 112. For installation and fixation with the vehicle body, the distance detecting component 12 is installed and fixed in the containing shell 112 and the containing shell 112 is rotatably connected with the mounting shell 111 so that the distance detection direction of the distance detecting component 12 can be adjusted with the rotation of the containing shell 112.
通过将安装壳111安装于车体2上作为固定部分，将可相对安装壳111转动的容纳壳112作为活动部分，并将距离探测部件12安装于容纳壳112内，通过转动容纳壳112可改变距离探测部件12相对于车体2的角度，实现了车载距离探测装置1的角度可调，无需外加调节支架，占用空间较小，使整车的外形更加美观。By installing the mounting shell 111 on the vehicle body 2 as a fixed part, the receiving shell 112 that can rotate relative to the mounting shell 111 is used as a movable part, and the distance detecting component 12 is installed in the receiving shell 112, which can be changed by rotating the receiving shell 112 The angle of the distance detecting component 12 relative to the vehicle body 2 realizes that the angle of the vehicle-mounted distance detecting device 1 can be adjusted without an additional adjustment bracket, which occupies a small space and makes the appearance of the entire vehicle more beautiful.
在本实施例中，所述容纳壳112呈球型状，所述安装壳111内限定出可供容纳壳112绕其球形中心偏转预设范围内的一定角度的活动空间，在其他实施例中，容纳壳112还可呈柱状。采用球型状的容纳壳112，一方面，容纳壳112与活动空间相适配，实现容纳壳112的转动可调，另一方面，也充分的利用了安装壳111的内部安装空间，使壳体11内部结构更加紧凑，壳体11更加小型化。In this embodiment, the receiving shell 112 is in a spherical shape, and the mounting shell 111 defines a movable space with a certain angle within a preset range for the receiving shell 112 to deflect around its spherical center. In other embodiments , The receiving shell 112 can also be cylindrical. The spherical housing shell 112 is adopted. On the one hand, the housing shell 112 is adapted to the movable space to realize the adjustable rotation of the housing shell 112. On the other hand, the internal installation space of the mounting shell 111 is also fully utilized to make the housing The internal structure of the body 11 is more compact, and the housing 11 is more compact.
进一步地，所述壳体11包括弹性夹紧于安装壳111和容纳壳112之 间并为容纳壳112提供阻尼作用的连接套113，还包括盖设于安装壳111底部的底盖114，所述底盖114和连接套113共同限定出所述活动空间。具体地，所述容纳壳112包括弧面部1121，所述连接套113的内侧壁呈弧形设置并与所述弧面部1121相贴合，为容纳壳112提供较高的阻尼作用。Further, the housing 11 includes a connecting sleeve 113 elastically clamped between the mounting shell 111 and the receiving shell 112 and providing a damping effect for the receiving shell 112, and also includes a bottom cover 114 covering the bottom of the mounting shell 111, so The bottom cover 114 and the connecting sleeve 113 jointly define the movable space. Specifically, the receiving shell 112 includes an arc surface 1121, and the inner side wall of the connecting sleeve 113 is arranged in an arc shape and is attached to the arc surface 1121 to provide the receiving shell 112 with a higher damping effect.
结合图5所示，进一步地，所述容纳壳112的外壁上凸出设有导向凸起1122，所述连接套113上开设有可供所述导向凸起1122通过的避空槽1131，所述安装壳111上开设有可供所述导向凸起1122嵌入的导向槽1119，所述导向凸起1122可沿所述导向槽1119滑动使容纳壳112水平转动调节。在本实施例中，容纳壳112的外壁上对称设置有两个导向凸起1122，所述安装壳111上也对应地设置有两个所述导向槽1119。在其他实施例中，容纳壳112的外壁上也可仅设置一个导向凸起1122。As shown in FIG. 5, further, a guide protrusion 1122 protrudes from the outer wall of the receiving shell 112, and an escape groove 1131 for the guide protrusion 1122 to pass is opened on the connecting sleeve 113, so The mounting shell 111 is provided with a guiding groove 1119 into which the guiding protrusion 1122 can be inserted, and the guiding protrusion 1122 can slide along the guiding groove 1119 to make the receiving shell 112 rotate and adjust horizontally. In this embodiment, two guiding protrusions 1122 are symmetrically provided on the outer wall of the receiving shell 112, and two guiding grooves 1119 are correspondingly provided on the mounting shell 111. In other embodiments, only one guiding protrusion 1122 may also be provided on the outer wall of the receiving shell 112.
进一步地，所述导向凸起1122呈半球状使所述容纳壳112可绕着导向凸起1122上下转动调节。由于毫米波雷达的距离探测部件12具有方向性，通过设置半球形的导向凸起1122与安装壳111上的导向槽1119的配合结构，限制了安装于容纳壳112内的距离探测部件12的转动方向，使其仅能实现左右摆动和上下摆动，在调节校准毫米波雷达的探测角度时，由于仅需要调节两个方向的角度，调节效率更高，而且也可以极大地保证毫米波雷达安装方向的准确性，减小检测误差。Further, the guiding protrusion 1122 is in a hemispherical shape, so that the receiving shell 112 can be rotated and adjusted up and down around the guiding protrusion 1122. Since the distance detection component 12 of the millimeter wave radar is directional, the rotation of the distance detection component 12 installed in the receiving shell 112 is restricted by the matching structure of the hemispherical guide protrusion 1122 and the guide groove 1119 on the mounting shell 111. Direction, so that it can only swing left and right and swing up and down. When adjusting and calibrating the detection angle of millimeter-wave radar, since only the angles in two directions need to be adjusted, the adjustment efficiency is higher, and the installation direction of millimeter-wave radar can also be greatly ensured Accuracy, reduce the detection error.
在本实施例中，所述容纳壳112包括前容纳壳1123和后容纳壳1124，所述前容纳壳1123和后容纳壳1124均呈半球状且两者相互扣合固定。所述距离探测部件12包括电路板组件和探测芯片121，所述电路板组件包括多个沿容纳壳112的中轴线平行排布的电路板122，且电路板122的厚度方向与该中轴线方向相同，所述电路板组件安装于前容纳壳1123内并与前容纳壳1123的内壁适配安装，具体地，多个电路板122的尺寸不一，且每个电路板122的尺寸与其所在的圆截面的直径相对应。所述探测芯片121安装于远离所述后容纳壳1124的电路板122上，且所述探测芯片121具体为毫米波射频芯片，探测芯片121采用的是长宽为1.22cm的新型芯片，壳体11的直径可达到2.8cm以下。In this embodiment, the receiving shell 112 includes a front receiving shell 1123 and a rear receiving shell 1124, and the front receiving shell 1123 and the rear receiving shell 1124 are both hemispherical in shape and they are fastened to each other. The distance detection component 12 includes a circuit board assembly and a detection chip 121. The circuit board assembly includes a plurality of circuit boards 122 arranged in parallel along the central axis of the housing shell 112, and the thickness direction of the circuit board 122 is the same as the central axis direction. Similarly, the circuit board assembly is installed in the front receiving shell 1123 and fitted with the inner wall of the front receiving shell 1123. Specifically, the size of the plurality of circuit boards 122 is different, and the size of each circuit board 122 is different from the size of the circuit board 122 where it is located. The diameter of the circular section corresponds to that. The detection chip 121 is mounted on the circuit board 122 far away from the rear housing shell 1124, and the detection chip 121 is specifically a millimeter wave radio frequency chip. The detection chip 121 uses a new type chip with a length and width of 1.22 cm. The diameter of 11 can reach 2.8cm or less.
由于容纳壳112呈球形结构，因此容纳壳112内的安装空间也呈球形，通过采用多层电路板122平行排布的结构，一方面可以更好地利用容纳壳112内的活动空间，使探测芯片121和其余的电器元件可分别排布于不同的电路板122上，而无需集成于同一个电路板122上，可大大地减小容纳壳112的尺寸，进而使毫米波雷达更加小型化。另一方面，由于容纳壳112呈球状，通过在最小的电路板122上排布探测芯片121，使该电路板122的尺寸与探测芯片121的尺寸相近，可缩小探测芯片121与前容纳壳1123前端的距离，减小探测芯片121所受到的信号遮挡影响，提高车载距离探测装置1的探测精确度。Since the receiving shell 112 has a spherical structure, the installation space in the receiving shell 112 is also spherical. By adopting a structure in which the multi-layer circuit board 122 is arranged in parallel, on the one hand, the movable space in the receiving shell 112 can be better utilized to make detection The chip 121 and the other electrical components can be arranged on different circuit boards 122 separately, without being integrated on the same circuit board 122, which can greatly reduce the size of the housing 112 and further miniaturize the millimeter wave radar. On the other hand, since the receiving shell 112 is spherical, the detection chip 121 is arranged on the smallest circuit board 122, so that the size of the circuit board 122 is similar to the size of the detection chip 121, and the detection chip 121 and the front receiving shell 1123 can be reduced. The distance of the front end reduces the influence of signal blocking on the detection chip 121 and improves the detection accuracy of the vehicle-mounted distance detection device 1.
在本实施例中，电路板组件包括两个电路板122，在其他实施例中，所述电路板122还可根据实际需要设置两个以上。两个所述电路板122之间设有使两者相互固定并于两者之间形成间隔的连接片123，具体地，所述连接片123为导热金属片，在本实施例中，连接片123采用黄铜材质制成。In this embodiment, the circuit board assembly includes two circuit boards 122.

Specifically, the connecting piece 123 is a thermally conductive metal piece. In this embodiment, the connecting piece 123 is made of brass.
利用连接片123支撑于两个电路板122之间，对两个电路板122进行支撑固定，并在电路板122之间形成间隔，可以为电路板122上的电器元件提供安装空间，防止电器元件受到挤压受损，另外两个电路板122之间形成的间隔也为探测芯片121提供了较大的散热空间，加上连接片123采用导热金属片，加快了探测芯片121的导热散热，保持探测芯片121工作温度的稳定，提高探测精确度。The connecting piece 123 is used to support between the two circuit boards 122, to support and fix the two circuit boards 122, and to form an interval between the circuit boards 122, which can provide installation space for the electrical components on the circuit board 122 and prevent the electrical components. Due to compression and damage, the space formed between the other two circuit boards 122 also provides a larger heat dissipation space for the detection chip 121. In addition, the connecting piece 123 uses a thermally conductive metal sheet, which speeds up the heat conduction and heat dissipation of the detection chip 121 and maintains The stability of the working temperature of the detection chip 121 improves the detection accuracy.
进一步地，所述连接片123包括支托于相邻两个电路板122之间的支托部1231，以及连接于所述支托部1231两端且可折弯变形的折弯部1232，所述电路板122上开设有可供所述折弯部1232穿过的穿孔1221，所述连接片123借助所述折弯部1232穿过所述穿孔1221后扣置于电路板122上从而使两个电路板122连接固定。具体地，折弯部1232穿过穿孔1221并折弯后可与电路板122焊接固定，以提高连接片123与电路板122的连接稳定性。Further, the connecting piece 123 includes a supporting portion 1231 supported between two adjacent circuit boards 122, and a bending portion 1232 that is connected to both ends of the supporting portion 1231 and can be bent and deformed. The circuit board 122 is provided with a through hole 1221 through which the bent portion 1232 can pass. The connecting piece 123 passes through the through hole 1221 by means of the bent portion 1232 and then is buckled on the circuit board 122 so that the two The two circuit boards 122 are connected and fixed. Specifically, the bent portion 1232 passes through the through hole 1221 and can be welded and fixed to the circuit board 122 after being bent, so as to improve the connection stability between the connecting piece 123 and the circuit board 122.

由于本实施例中的毫米波雷达的整体体积较小，壳体11的散热面积较小，在本实施例中，所述连接套113采用导热硅胶制成，所述安装壳111、容纳壳112和底盖114均采用尼龙6材质制成。Since the overall volume of the millimeter wave radar in this embodiment is small, and the heat dissipation area of the housing 11 is small, in this embodiment, the connecting sleeve 113 is made of thermally conductive silicone, and the mounting shell 111 and the receiving shell 112 Both the bottom cover 114 and the bottom cover 114 are made of nylon 6 material.
本发明通过采用导热材料以及安装壳111、容纳壳112、连接套113和底盖114各个结构的合理分布，在使毫米波雷达更加小型化的同时，使其具备较好的散热性能，确保探测芯片121处于正常的温度下工作，提高其探测的精确性。具体地，电路板122上的探测芯片121和电器元件所产生的热量通过电路板122或内部空间间隔传递至容纳壳112上，容纳壳112与连接套113和底盖114直接接触，将热量传递至连接套113和底盖114，连接套113再将热量传递至安装壳111，使热量由内向外呈球形向外扩散。由于容纳壳112、连接套113、容纳壳112和底盖114相互之间的连接较为紧密，结构也较为紧凑，相互之间的间隙较小，即容纳壳112向外的导热过程大部分通过导热材料进行传递，导热速度相比于通过间隙之间的空气导热要快，使毫米波雷达兼具了小型化和散热效果良好的性能。The present invention adopts the heat-conducting material and the reasonable distribution of the various structures of the mounting shell 111, the receiving shell 112, the connecting sleeve 113 and the bottom cover 114, while making the millimeter wave radar more compact, it has better heat dissipation performance and ensures detection The chip 121 works at a normal temperature, which improves the accuracy of its detection. Specifically, the heat generated by the detection chip 121 and the electrical components on the circuit board 122 is transferred to the receiving shell 112 through the circuit board 122 or the internal space interval, and the receiving shell 112 is in direct contact with the connecting sleeve 113 and the bottom cover 114 to transfer the heat To the connecting sleeve 113 and the bottom cover 114, the connecting sleeve 113 transfers heat to the mounting shell 111, so that the heat diffuses outward in a spherical shape from the inside to the outside.
