The structure, function and implementation procedure of the domain controller according to the embodiment of the present utility model are described below by way of example with reference to the accompanying drawings.

It will be appreciated that other structures and functions of the domain controller according to the embodiments of the present utility model are known to those skilled in the art, and are not described herein for redundancy reduction.

It should be noted that: for convenience of description, the present embodiment is directed upward in the direction indicated by the arrow Z in the drawing, rearward in the direction indicated by the arrow X in the drawing, and rightward in the direction indicated by the arrow Y in the drawing.

Referring to fig. 1 to 5, a domain controller provided in this embodiment is used for a vehicle, and includes: a housing 1, a connector 2 and an elastic member 3. Wherein the housing 1 can enclose a relatively closed installation space in which electronic components such as control circuits of the domain controller are located. The housing 1 is provided with a mounting hole 1a communicating with the mounting space, the axial direction of the mounting hole 1a is parallel to an arrow X in fig. 1, the connector 2 is inserted into the mounting hole 1a, and the connector 2 is electrically connected with a control circuit in the housing 1 to electrically connect the control circuit of the domain controller with external hardware equipment. The elastic member 3 is abutted between the connector 2 and the housing, for example, the elastic member 3 is abutted between the connector 2 and the wall of the mounting hole 1a to absorb the fit gap between the connector 2 and the wall of the mounting hole 1a of the housing.

At least one of the housing 1 and the connector 2 is provided with a positioning groove 2a, and a part of the elastic member 3 is located in the positioning groove 2a. In some examples, the connector 2 is provided with a positioning groove 2a, a part of the elastic member 3 is located in the positioning groove 2a, and a part of the elastic member 3 located outside the positioning groove 2a absorbs a fit clearance between the connector 2 and a hole wall of the mounting hole 1a of the housing, and can facilitate assembly of the domain controller.

In other examples, the hole wall of the mounting hole 1a of the housing 1 is provided with a positioning groove 2a, a part of the elastic member 3 is located in the positioning groove 2a, and a part of the elastic member 3 located outside the positioning groove 2a absorbs the fit clearance between the connector 2 and the hole wall of the mounting hole 1a of the housing.

For convenience of description, the present embodiment will be described taking the case where the positioning groove 2a is provided on the connector 2 as an example. When the positioning groove 2a is provided to the hole wall of the mounting hole 1a of the housing 1, the implementation is similar to the present embodiment.

One part of the elastic member 3 is located in a positioning groove 2a formed on the connector 2, and the other part of the elastic member 3 extends out of the positioning groove 2a, that is, the other part of the elastic member 3 is located outside the positioning groove 2a. In some examples, the portion of the elastic member 3 located outside the positioning groove 2a may abut against the hole wall of the mounting hole 1a and be elastically deformed, and the elastic member 3 has a certain elastic deformation amount. In other examples, the portion of the elastic member 3 located outside the positioning groove 2a may have a certain clearance with the hole wall of the mounting hole 1a, which can satisfy the requirement of less than or equal to 1 mm.

The domain controller provided in this embodiment includes: a housing 1, the housing 1 being provided with a mounting hole 1a; a connector 2, the connector 2 is inserted into the mounting hole 1a, and the connector 2 is used for electrically connecting with a control circuit in the shell 1; the elastic piece 3 is abutted between the connector 2 and the shell and used for absorbing a fit clearance between the connector 2 and the shell; wherein at least one of the housing 1 and the connector 2 is provided with a positioning groove 2a, and a part of the elastic member 3 is located in the positioning groove 2a. Therefore, the elastic piece 3 can absorb the fit clearance between the connector 2 and the shell, so that the fit clearance between the connector 2 and the shell can meet the preset requirement, and the assembly quality qualification rate of the connector 2 and the shell 1 is improved; moreover, a part of the elastic member 3 is located in the positioning groove 2a, so that the elastic member 3 can be prevented from being displaced relative to the connector 2 or the housing 1, and thus the installation reliability of the elastic member 3 is ensured, and the situation that the fit clearance between the connector 2 and the housing cannot meet the preset requirement due to the displacement of the elastic member 3 is avoided.

In some embodiments, the connector 2 is provided with a positioning groove 2a, and the positioning groove 2a is provided extending in the circumferential direction of the connector 2. A part of the elastic member 3 is located in the positioning groove 2a, and a part of the elastic member 3 abuts against the wall of the mounting hole 1a on the housing 1 and has an elastic deformation amount.

Generally, the connector 2 has a columnar structure, and the axial direction of the connector 2 is parallel to the axial direction of the mounting hole 1a. The positioning groove 2a may extend in the circumferential direction of the connector 2, the circumferential direction of the connector 2 being perpendicular to the axial direction of the connector 2. Illustratively, the detent recesses 2a are provided around the connector 2. Correspondingly, the elastic element 3 may also be annular. In this way, the elastic piece 3 not only can absorb the fit clearance between the connector 2 and the hole wall of the mounting hole 1a of the shell, but also is beneficial to keeping the connector 2 in the central area of the mounting hole 1a under the action of elastic potential energy stored by compression deformation of the elastic piece 3, so that the connector 2 is in a balanced state, and further, the clearance between the connector 2 and the hole wall of the mounting hole 1a can meet preset requirements everywhere along the circumferential direction of the mounting hole 1a.

In some examples, the shape of the elastic member 3 may be adapted to the shape of the positioning groove 2a, so that the elastic member 3 can be better fitted with the positioning groove 2a. For example, if the connector 2 is prismatic, the bottom wall of the positioning groove 2a is also substantially prismatic, and accordingly, the elastic member 3 may be a prismatic ring structure.

In a specific implementation process, a common sealing material can be adopted, and the elastic piece 3 which is matched with the shape of the positioning groove 2a can be prepared by utilizing the preparation process of the sealing ring.

In other examples, the elastic member 3 is an O-ring seal to further reduce cost. Wherein, because the O-shaped sealing ring has certain elasticity, the annular shape of the sealing ring can correspondingly change along with the annular shape of the positioning groove 2a.

In other embodiments, the positioning groove 2a is semi-annular and extends along the circumferential direction of the connector 2, and correspondingly, the elastic member 3 is also semi-annular, and the portion of the elastic member 3 extending out of the positioning groove 2a can absorb the fit clearance between the connector 2 and the housing. Moreover, under the action of elastic potential energy of the elastic piece 3, the elastic piece 3 can forcedly push the connector 2 along the direction away from the elastic piece 3 so as to reduce the fit clearance of the connector 2 at the side away from the elastic piece 3, thereby enabling the fit clearance between the connector 2 and the shell to meet the requirement.

Referring to fig. 6, and with continued reference to fig. 1 to 4, in some embodiments, a portion of the elastic member 3 is located in the positioning groove 2a of the connector 2, and a portion of the elastic member 3 abuts against a hole wall of the mounting hole 1a on the housing 1 and has an elastic deformation amount, where the elastic deformation amount is less than or equal to fifty percent of an initial dimension D of the elastic member 3 along the compression direction. Wherein the compression direction is perpendicular to the axial direction of the mounting hole 1a. The initial dimension D of the elastic member 3 in the compression direction is the dimension of the elastic member 3 in the compression direction in the initial state (when not pressed). When the elastic member 3 is annular, the initial dimension D of the elastic member 3 in the compression direction is a dimension difference between the inner ring and the outer ring on one side. In this way, irreversible deformation of the elastic member 3 can be avoided, thereby facilitating ensuring functional reliability of the elastic member 3 and prolonging the service life of the elastic member 3.

The elastic deformation amount of the elastic member 3 is the dimensional change amount of the elastic member 3 in the compression direction. That is, the elastic deformation amount of the elastic member 3 is a difference between the initial dimension of the elastic member 3 in the initial state in the compression direction and the pressed dimension of the elastic member 3 in the pressed state in the compression direction.

For example, the elastic deformation amount of the elastic member 3 may be fifty percent of the initial dimension D of the elastic member 3 in the compression direction, forty percent of the initial dimension D of the elastic member 3 in the compression direction, thirty percent of the initial dimension D of the elastic member 3 in the compression direction, twenty percent of the initial dimension D of the elastic member 3 in the compression direction, ten percent of the initial dimension D of the elastic member 3 in the compression direction, one percent of the initial dimension D of the elastic member 3 in the compression direction, or between any two of the above.

In some examples, the depth of the detent groove 2a in the compression direction is fifty percent of the initial dimension D of the elastic member 3 in the compression direction to ensure that the elastic deformation amount of the elastic member 3 does not exceed fifty percent of the initial dimension D of the elastic member 3 in the compression direction. Wherein, the positioning groove 2a includes two sidewalls that set up relatively to and connect the diapire between two sidewalls, two sidewalls deviate from the one side of diapire and enclose into the notch, and the degree of depth of positioning groove 2a is the distance between notch and the diapire. In other examples, the depth of the positioning groove 2a on the connector 2 may be slightly larger than fifty percent of the initial dimension of the elastic member 3 in the compression direction.

For example, the actual gap between the connector 2 and the wall of the mounting hole 1a on the housing 1 is 0.3 mm, the protruding dimension of the elastic member 3 from the connector 2 is 0.5 mm, and the interference amount, i.e. the elastic deformation amount, of the elastic member 3 after the assembly is 0.2 mm. The initial dimension of the elastic member 3 in the compression direction is 1 mm, that is, the diameter of the single side of the elastic member 3 is 1 mm, and the depth of the positioning groove 2a on the connector 2 is 0.5 mm.

In this way, the connector 2 is matched with the shell 1 through the elastic piece 3, the elastic piece 3 can absorb the fit clearance between the connector 2 and the shell 1, the size chain ring shrinkage is shortened, the fit clearance between the connector 2 and the shell can meet the preset requirement, and the assembly quality qualification rate of the connector 2 and the shell 1 is improved; moreover, because of the existence of the elastic member 3, the elastic member 3 can apply a certain acting force to the connector 2 under the condition of extreme compression, thereby ensuring that the connector is always at the center position of the mounting hole 1a, so that the connector 2 is in a balanced state, and the clearance between the connector 2 and the wall of the mounting hole 1a along the circumferential direction thereof meets the requirement.

In addition, due to the arrangement of the elastic piece 3, the size chain ring is shortened, correspondingly, the tolerance requirements of other structures in the domain controller can be reduced, and the cost of the domain controller is reduced.

Referring to fig. 7, in some embodiments, the housing 1 includes: the first housing 11 and the second housing 12 are connected, and the control circuit is located in the installation space surrounded by the first housing 11 and the second housing 12. Taking the first casing 1 and the second casing 1 as examples, the first casing 1 is located above the second casing 1, the first casing 1 is a box body with a lower opening, and the second casing 1 is a cover plate covering the lower opening of the first casing 1.

In some examples, the dimension of the first side edge of the first housing 11 in the up-down direction is smaller than the dimension of the second side edge in the up-down direction, and accordingly, the edge of the second casing 1 corresponding to the first side edge has a turned-up folded edge. The first side of the first housing 11 is provided with a first mounting groove 11a, and the turnover edge of the second housing 12 is provided with a second mounting groove 12a. When the first housing 11 is connected to the second housing 12, the first mounting groove 11a is opposed to the second mounting groove 12a and the mounting hole 1a is formed. In this way, the mounting of the connector 2 is facilitated.

Referring to fig. 8, in the assembly, the elastic member 3 may be first placed in the positioning groove 2a of the connector 2, the connector 2 may be placed in the first mounting groove 11a or the second mounting groove 12a, and then the first mounting groove 11a may be opposite to the second mounting groove 12a, and the first housing 11 may be connected to the second housing 12. After the first housing 11 and the second housing 12 are connected, the elastic member 3 can abut against the bottom walls of the first mounting groove 11a and the second mounting groove 12a.

In other examples, the first side and the second side of the first housing 11 may be equal in size in the up-down direction, and the first side may be provided with the mounting hole 1a. In assembly, the elastic member 3 is placed in the positioning groove 2a of the connector 2, and then the connector 2 is inserted into the mounting hole 1a.
