Automobile data recorder

The invention discloses an automobile data recorder, and belongs to the field of vehicle accessories. The automobile data recorder comprises a screen, a shell is arranged on the back of the screen, a plurality of first heat dissipation holes are formed in the shell, dustproof sheets are fixedly connected to the position, close to the upper portion of the first heat dissipation holes, of the shell, and the area of the dustproof sheets is equal to that of the end faces of the first heat dissipation holes; and a distance is formed between the dustproof sheets and the first heat dissipation holes. In the using process, heat is dissipated through the first heat dissipation holes, then the dustproof sheets play a dustproof role, dust entering from the first heat dissipation holes is reduced, and the heat dissipation and dustproof effects are achieved. 本发明公开了一种行车记录仪，属于车辆配件的领域，其包括屏幕，所述屏幕背面设有壳体，所述壳体上开设有若干第一散热孔，所述壳体靠近所述第一散热孔上方固定连接有防尘片，所述防尘片的面积与所述第一散热孔端面面积等大，所述防尘片与所述第一散热孔之间有距离。本申请使用过程中，通过第一散热孔散热，然后防尘片起到防尘作用，减少灰尘从第一散热孔进入
