STATE OF THE ART

With the rapid development of cities, automobiles are becoming more and more popular, and as the “brain” of an automobile, an electronic control unit (ECU) for an automobile has more and more functions. An ECU collects data from various sensors on the motor vehicle, e.g. Temperature sensor, pressure sensor, rotation sensor, flow sensor, position sensor, oxygen sensor, liquid level sensor and knock sensor, then performs a calculation and then converts the result into a control signal to control a controlled object to perform an appropriate operation. It plays an important role in the normal and safe operation of a motor vehicle. In the prior art, the ECU control unit and its housing are complicated to assemble and have insufficient stability when mounted on the motor vehicle. Furthermore, control devices in the prior art are passively cooled, which leads to an inadequate cooling effect. Therefore, there is a need for an ECU that is easy to assemble, firmly attach and has good cooling effect.

Embodiment

A motor vehicle ECU control unit includes a housing 1 for installing a control unit main board 5 , the case being an upper case 11 and a lower case 12 which are arranged one above the other comprises. The upper housing has a first mounting eyelet on two opposite sides 111 provided for mounting, while a second mounting eyelet on the side wall of the lower housing 121 is provided, which is located on a side adjacent to the first two mounting eyes. A feed-through opening is located on the side opposite the second mounting eyelet 3 , over which a connector element of the control unit main board protrudes, is provided.

The first connection eyelet, which is used for assembly and fastening, is arranged on the upper housing and, after assembly and locking, the assembly stability of the control device can be increased by a structure that is similar to a clamp. Furthermore, without providing a further fastening device (for example by locking by means of a bolt) between the upper housing and the lower housing can be snapped on in a stable manner.

The control unit main board is attached to the upper housing and one side edge of the control unit main board has several recesses 51 with the upper housing having a rib that can be snapped into the recess 112 having. The recess and the rib, which are in latching connection with one another, limit displacement of the control unit main board in the horizontal direction.

In the same way, the snap-in connection of the recess and the rib limits the control unit main board, so that fastening, etc. can be omitted via a bolt, which makes assembly easier.

The upper housing is made of aluminum and the lower housing is made of aluminum or plastic. Since the upper case serves as the main mounting component, the use of a metallic component contributes to better strength. Furthermore, in the present exemplary embodiment, the upper housing is also provided with cooling fins, which is why a housing made of aluminum is preferably used.

Two opposite sides of the upper housing each have several cooling fins 113 on, between which a cooling grille penetrating the surface of the upper housing 114 is provided.

Furthermore, the inside of the cooling grille (the inside of the upper housing) is provided with a dust protection net (not shown).

The upper surface of the upper case is with a cooling fan 4th provided that draws power from the control unit main board, the cooling fan preferably blowing air to the outside. The cooling fan sucks warm air out of the control unit and sucks in outside air through the cooling grille in order to enable air to circulate and thus increase cooling efficiency.

The bottom surface of both the first mounting eyelet and the second mounting eyelet protrudes from the bottom surface of the lower housing. By providing a protruding structure on the control unit, contact with the motor vehicle or squeezing of the lower housing is prevented in the assembled state, whereby damage to the housing and the control device main board caused by squeezing can be prevented.

The lower surface of the first mounting eye has several protruding teeth 1111 on, whereby the first mounting eyelet is locked with a bolt and after reaching a certain moment a deformation of the teeth can be caused, whereby the locking force of the bolt is increased (like with a spring washer) and a detachment of the control unit due to a loosened bolt is prevented .

The upper housing and the lower housing can then be firmly connected to one another by snapping them on and / or using a screw.

In the present embodiment, a snap structure is used to support the fixed connection between the upper housing and the lower housing. Due to the first mounting eyelet, a fixed attachment can be made no need for a screw and snap-on assembly or disassembly is made easier.

The inner surface of the lower case has multiple support pillars 122 to support the control unit main board.

The control unit main board is supported by the support columns and a free space is thus kept free below the control unit main board in order to form a channel through which the air flows and thus improve the cooling effect.

In the description of the present utility model, the terms “central”, “top”, “bottom”, “left”, “right”, “vertical”, “horizontal”, “inside”, “outside”, etc. are used in relation to each other to the description of the exemplary embodiment and the representation in the respective illustration or the orientation or positional relationship of the product according to the present utility model in a normal position during use, in order to merely describe the utility model and, if necessary, to simplify the description. In other words, these terms are not used either implicitly or explicitly to indicate the positioning, design and operation of the device or element in question in a predetermined positioning, so that there is no limitation of the utility model here either.

• Bei dem ECU-Steuergerät nach dem vorliegenden Gebrauchsmuster ist das obere Gehäuse an zwei gegenüberliegenden Seiten jeweils mit einer ersten Montageöse zur Montage versehen, während an der Seitenwand des unteren Gehäuses eine zweite Montageöse vorgesehen ist, wobei die zur Montage und Befestigung dienende erste Verbindungsöse an dem oberen Gehäuse angeordnet ist und nach Montage und Verriegeln die Montagestabilität des Steuergeräts durch eine Struktur, die einer Klemmschelle ähnelt, erhöht werden kann. Des Weiteren kann ohne Vorsehen einer weiteren Befestigungsvorrichtung (beispielsweise durch Verriegeln mit einem Bolzen) zwischen dem oberen Gehäuse und dem unteren Gehäuse ein stabiles Aufschnappen ermöglicht werden.

The working principle of the present utility model is as follows:

• In the ECU control unit according to the present utility model, the upper housing is provided on two opposite sides with a first mounting eyelet for mounting, while a second mounting eyelet is provided on the side wall of the lower housing, the first connecting eyelet serving for mounting and attachment to the Upper housing is arranged and after assembly and locking, the assembly stability of the control unit can be increased by a structure that is similar to a clamp. Furthermore, a stable snapping on can be made possible without providing a further fastening device (for example by locking with a bolt) between the upper housing and the lower housing.

One side edge of the control unit main board has several recesses, the upper housing having a rib that can be snapped into the recess, so that the locking connection of the recess and the rib delimits the control unit main board and a fastening, etc. can be omitted via a bolt, which makes assembly easier.

The top surface of the upper case is provided with a cooling fan that draws power from the controller motherboard, the cooling fan preferably blowing air outside. The cooling fan sucks warm air out of the control unit and sucks in outside air via the cooling grille to allow air to circulate and thus increase cooling efficiency.

The lower surface of the first mounting eyelet has several protruding teeth, the first mounting eyelet being locked when a bolt is installed and, after a certain moment has been reached, the teeth can be deformed, thus increasing the locking force of the bolt and causing the control unit to become detached loosened bolt is prevented.

In the above, only one embodiment of the present utility model was explained without restricting the scope of the utility model.
