Abstract
The invention relates to a mounting structure of a sheet metal shell and a circuit board. The mounting structure includes a lower shell and an upper shell which sleeves the lower shell; the inner-side bottom surface of the lower shell is provided with two symmetrical male riveting columns; the male riveting columns are boss-shaped; the male riveting columns are sleeved with the circuit board; two symmetrical female riveting columns which are located at the inner-side top surface of the upper shell are arranged above the circuit board; the female riveting columns are in the shape of blind holes; the male riveting columns are inserted into the female riveting columns; springs are arranged between the outer walls of the male riveting columns and the inner walls of the female riveting columns; and the springs sleeve the male riveting columns. According to the mounting structure of the sheet metal shell and the circuit board of the invention, the male riveting columns are matched with the female riveting columns, so that the circuit board can be fixed, and the circuit board can be conveniently assembled and disassembled, and has little possibility of falling off; the springs are designed, so that precision requirements for the riveting height of the female riveting columns can be reduced, and therefore, manufacturing cost can be reduced; when the product is used in a vibration environment, the springs can play a role of buffering, and therefore, parts on the circuit board can be effectively protected from being damaged.
Description
Technical field
The present invention relates to electric automobile field, particularly relate to the mounting structure of a kind of sheet metal shell and circuit board.
Background technology
In recent years, automobile gets more and more, and TRANSPOWORLD is more and more crowded, thus causes municipal pollution more and more serious, and the city haze weather of China happens occasionally.In order to reduce municipal pollution, the application of electric automobile can be more and more general.In electric automobile, the installation great majority of the circuit board in sheet metal shell adopt the mode of fastened by screw, and the shortcoming of this mode is, must have vibrations during running car, and long-term vibrations then may make the screw loosening of fixing circuit board, even drop.When with the working on power of housing, the screw dropped due to vibrations play in housing of automobile, then may cause short circuit, and product function lost efficacy.Have method to propose and establish at cap the fixed leg of circuit board stretched out downwards, internal circuit board plate is just in time pushed down and is fixed by it.The shortcoming of this mode is: when product is vertically fixed, if pull down shell, then inner circuit board can directly drop; Just in time pushed down by circuit board to fixed leg, firm being fixed in housing of circuit board can not be rocked, then the precision of fixed leg height needs very high, and the manufacturing cost of corresponding housing can raise.
Summary of the invention
The object of this invention is to provide a kind of easy for installation, not easily drop, the sheet metal shell of low cost of manufacture and the mounting structure of circuit board.
The present invention is achieved through the following technical solutions above-mentioned purpose: the mounting structure of a kind of sheet metal shell and circuit board, comprise lower house and be sheathed on the upper shell on described lower house, described lower house inside bottom surface is provided with two symmetrical public riveting posts, described public riveting post is boss-shaped, described public riveting post is arranged with circuit board, described circuit board is provided with the symmetrical female riveting post of two of being positioned at end face inside described upper shell, described female riveting post is blind hole shape, described male riveting post inserts in described female riveting post, spring is provided with between the outer wall of described male riveting post and the inwall of described female riveting post, described spring housing is located on described public riveting post.
Further, described public riveting post and described lower house one-body molded.
Further, described female riveting post and described upper shell one-body molded.
Further, two symmetrical madial walls of described upper shell are equipped with upper limit portion, the both sides end face of described lower house is lower limit portion, and the both side ends of described circuit board is between described upper limit portion and described lower limit portion.
Further, be screwed between described upper shell and described lower house.
Compared with prior art; sheet metal shell of the present invention with the beneficial effect of the mounting structure of circuit board is: the mode fixing circuit board coordinated with female riveting post by male riveting post; easy accessibility; not easily drop, the design of spring, makes to reduce the required precision of female post height that presses; thus reduce manufacturing cost; and product when using in the environment shaken, the cushioning effect that spring can play, can parts effectively on protective circuit plate injury-free.
Accompanying drawing explanation
Fig. 1 is the exploded perspective view of mounting structure one better embodiment of a kind of sheet metal shell of the present invention and circuit board.
In figure, each mark is as follows: 1, upper shell, and 11, female riveting post, 12, upper limit portion, 2, lower house, 21, public riveting post, 22, lower limit portion, 3, circuit board, 4, spring, 5, screw.
Embodiment
Refer to accompanying drawing 1, the mounting structure of a kind of sheet metal shell and circuit board, the upper shell 2 comprising lower house 1 and be sheathed on described lower house, described lower house 1 inside bottom surface is provided with two symmetrical public riveting posts 21, described public riveting post is boss-shaped, described public riveting post is arranged with circuit board 3, female riveting post 11 that two of being positioned at end face inside described upper shell are symmetrical is provided with above described circuit board 3, described female riveting post is blind hole shape, described male riveting post inserts in described female riveting post, spring 4 is provided with between the outer wall of described male riveting post and the inwall of described female riveting post, described spring housing is located on described public riveting post, easy accessibility, not easily drop, low cost of manufacture.Described public riveting post and described lower house one-body molded, described female riveting post and described upper shell one-body molded, fixed by screw 5 between upper shell and described lower house.
Public riveting post is divided into upper and lower, the diameter on described top is less than bottom, described circuit board is provided with installing hole, and male riveting post top is inserted in female riveting post through installing hole, forms gap in top and female riveting post, described gap width is greater than the width of spring, spring can be stretched in gap, and spring makes gap portion fully support, and makes circuit board fixed, and when using in the environment shaken, spring can play the effect of buffering.
Two symmetrical madial walls of upper shell are equipped with upper limit portion 12, and the both sides end face of described lower house is lower limit portion 22, and the both side ends of described circuit board, between described upper limit portion and described lower limit portion, can play the effect strengthening positioning precision.
Above-described is only some embodiments of the present invention.For the person of ordinary skill of the art, without departing from the concept of the premise of the invention, can also make some distortion and improvement, these all belong to protection scope of the present invention.
