In order to facilitate understanding of the frame assembly provided in the embodiments of the present application, an application scenario thereof is first described. The frame subassembly that this application embodiment provided is applied to the car, as the major structure of car. Currently, as the intelligence of automobiles develops, the frame needs to carry more devices, such as a controller. The controller needs to be grounded when being arranged on the frame, and the current mode is that the controller is connected with the frame through a grounding wire, so that an extra grounding wire and a grounding bolt are needed. The following detailed description is made with reference to the specific drawings and examples.

Referring to fig. 1, fig. 1 shows a schematic structural diagram of a vehicle frame assembly provided by an embodiment of the present application. The frame subassembly that this application embodiment provided mainly includes the triplex, is controller, support and frame respectively. The frame is used as a bearing structure to bear the support and the controller; the bracket also serves as a carrying structure for carrying the controller. The structure of each part is described in detail below with reference to the accompanying drawings.

The controller 10 provided in the embodiments of the present application may be an autopilot domain controller or other type of controller. That is, the controller 10 provided in the embodiment of the present application is referred to as a controller 10 that can be carried by the vehicle frame 30. In the embodiment of the present application, an automatic driving range controller is taken as an example for description.

The controller 10 has a complex circuit board inside and an aluminum housing outside, often disposed under the floor in the cabin, and the controller 10 is covered with carpet above. If static electricity is generated by a carpet or a maintenance hand, the static electricity is conducted to an internal circuit board of the controller 10, which may cause damage to the controller 10; it is desirable to ground the housing of the controller 10 to conduct static electricity to the vehicle body to avoid damage to the circuit board within the controller 10.

In order to ensure the safety of the controller 10, in the embodiment of the present application, the controller 10 is grounded, that is, the housing of the controller 10 is electrically connected to the frame 30 to achieve grounding. The specific grounding path is as follows: controller 10-bracket 20-carriage 30. In specific implementation, the controller 10 is electrically connected to the bracket 20, and then electrically connected to the frame 30 through the bracket 20, so as to implement grounding of the controller 10.

Referring to fig. 1 and 2 together, fig. 2 is an exploded view of the stand 20 and the controller 10. The bracket 20 is fixedly connected to the controller 10 when installed and is used to carry the bracket 20 of the controller 10. As shown in fig. 2, the bracket 20 has a plate-like structure, and the bracket 20 is provided with a concave space for accommodating the controller 10. In a specific arrangement, the middle region of the bracket 20 is a concave groove 21, and the edge of the bracket 20 is a supporting edge 22, and the supporting edge 22 is arranged around the groove 21.

In the embodiment of the present application, the support 20 is made of a conductive metal, such as the support 20 made of a metal material such as aluminum, iron, etc.

The surface of the bracket 20 can be plated with a protective layer which is an insulating layer; or the surface of the support 20 is plated with a conductive metal layer. Illustratively, the bracket 20 is wrapped with a conductive coating, which may be a zinc coating, but is also other conductive metal layers, which are not specifically limited in the embodiments of the present application.

When the controller 10 is loaded, the controller 10 is placed on the stand 20 and fixed. And the housing of the controller 10 is electrically conductively connected to the bracket 20 when the controller 10 is fixed to the bracket 20. In the case of a specific electrically conductive connection, the electrically conductive connection can be carried out in different ways. The following description will be made separately.

Referring to fig. 2 and 3 together, fig. 3 shows a schematic connection diagram of the stand 20 and the controller 10. When the controller 10 is specifically fixed, the bracket 20 is fixedly connected to the housing of the controller 10 through the second connecting member 50, that is, the housing of the controller 10 is fixed to the bracket 20 through the second connecting member 50. As shown in fig. 2, when the controller 10 is placed on the stand 20, the controller 10 may be located in the groove 21 of the stand 20, and the edge of the housing of the controller 10 overlaps the support edge 22 of the stand 20. The second connecting member 50 is inserted into the edge of the housing of the controller 10 and the supporting edge 22 of the bracket 20, and presses and fixes the edge of the housing of the controller 10 and the supporting edge 22 of the bracket 20, so as to fixedly connect the controller 10 and the bracket 20.

In the embodiment of the present application, the second connector 50 is a conductive connector. In the case of an electrically conductive connection between the housing of the controller 10 and the carrier 20, the carrier 20 is electrically conductively connected to the housing of the controller 10 via the second connection 50. For example, when the surface of the bracket 20 is plated with a protective layer, since the second connector 50 is disposed through the bracket 20 and the housing of the controller 10, the second connector 50 may break the protective layer on the surface of the bracket 20, so that the bracket 20 and the housing of the controller 10 may be electrically connected.

As an alternative, the second connector 50 is a threaded connector. Specifically, the second connecting member 50 includes a rivet stud 51 and a nut 52. The rivet pressing stud 51 is arranged on the bracket 20, and when the rivet pressing stud 51 is specifically arranged, the rivet pressing stud 51 is riveted to the supporting edge 22 of the bracket 20 from one side of the bracket 20, which is away from the controller 10, and a screw of the rivet pressing stud 51 passes through the bracket 20 and then is exposed outside the bracket 20 so as to be matched with a shell of the controller 10. When the rivet pressing stud 51 is fixed on the bracket 20, the rivet pressing stud 51 is electrically connected with the bracket 20.

The shell of the controller 10 is sleeved on the rivet pressing stud 51; the nut 52 compresses the housing of the controller 10 against the bracket 20. Illustratively, a through hole matched with the rivet pressing stud 51 is formed in a housing of the controller 10, and during assembly, the housing of the controller 10 is inserted into the rivet pressing stud 51, and then a nut 52 is screwed in to press and fix the housing of the controller 10 and the bracket 20. In the case of the conductive connection, since the nut 52 is conductively connected to the housing of the controller 10 and the nut 52 is conductively connected to the rivet bolt 51, the housing of the controller 10 and the bracket 20 can be conductively connected by the second connection member 50.

It should be understood that the threaded connection of the above example is only one specific example of the second connection 50. The second connector 50 provided in the embodiment of the present application may also adopt other threaded connectors besides the above-mentioned example of the engagement between the rivet pressing stud 51 and the nut 52. If the connection is made by using a self-tapping screw, the self-tapping screw can also destroy the protective layer of the bracket 20, so that the conductive connection between the housing of the controller 10 and the bracket 20 is realized. Alternatively, the second connector 50 may be a rivet, instead of a threaded connector, and may also be an electrically conductive connection between the bracket 20 and the controller 10.

As can be seen from the above description, the second connecting member 50 is provided as both a connecting structure and a conductive structure to achieve the conductive connection of the controller 10 and the stand 20. When the bracket 20 is electrically connected with the housing of the controller 10, the controller 10 can be fixed and electrically connected by using the structural member for fixed connection as an electrically conductive member without adding an additional electrically conductive member.

As an alternative, the number of the second connecting members 50 provided in the embodiment of the present application is plural, and the plural second connecting members 50 are disposed along the corners of the bracket 20. Illustratively, the number of the second connecting members 50 is four, and four second connecting members 50 are disposed along four corners of the bracket 20, so as to improve the fixation of the controller 10 by the plurality of second connecting members 50, and at the same time, improve the grounding effect between the housing of the controller 10 and the bracket 20. It should be understood that the number of the second connection members 50 provided in the embodiment of the present application is not limited to four, and other numbers may be provided. Illustratively, the number of second connectors 50 may be two, three, five, etc. in different numbers. And when specifically arranged, the second connecting member 50 may be arranged around the edge of the housing of the controller 10, so as to reduce the ground resistance through the different second connecting members 50, and improve the conductive connection effect between the housing of the controller 10 and the bracket 20.

When the bracket 20 is coated with the conductive coating, the housing of the controller 10 provided in the embodiment of the present application may also be electrically connected by directly connecting with the conductive coating of the bracket 20. Illustratively, when the second connector 50 fixes the controller 10 on the bracket 20, the housing of the controller 10 is pressed against the conductive coating and is electrically connected with the bracket 20 through the conductive coating. In this case, the second connecting member 50 may be a conductive member or an insulating member. However, no matter the second connecting member 50 is a conductive member or an insulating member, when the second connecting member 50 presses and fixes the housing of the controller 10 on the bracket 20, the housing of the controller 10 can be electrically connected with the bracket 20 through the conductive plating layer. In addition, when the second connecting member 50 is a conductive member, the housing of the controller 10 and the bracket 20 may be electrically conductive through the second connecting member 50, or may be electrically conductive through the conductive plating layer, so as to further improve the conductive effect between the bracket 20 and the controller 10.

Referring also to fig. 4, fig. 4 is a schematic view showing a structure in which the bracket 20 is coupled to the frame 30. After the controller 10 and the bracket 20 are fixed, the controller 10 and the bracket 20 are fixed to the frame 30. In a specific arrangement, the frame assembly provided by the embodiment of the present application further includes a first connecting member 40, and the first connecting member 40 serves as both a fixed connecting member and a conductive connecting member.

In a particular arrangement, the first connector 40 may be a self-tapping threaded connector. During assembly, the bracket 20 may be fixedly connected to the frame 30 by a self-tapping connector, and the bracket 20 is electrically connected to the frame 30 by a self-tapping connector. The electrophoretic paint on the frame 30 is destroyed through the self-tapping thread connecting piece, and the self-tapping thread connecting piece is used as a connecting piece and a conductive piece, so that the conductive effect between the bracket 20 and the frame 30 is realized.

When the frame 30 is specifically arranged, the frame 30 includes a first seat cross member 31 and a second seat cross member 32 which are arranged at intervals, the bracket 20 is fixedly connected with the first seat cross member 31 and the second seat cross member 32 through a first connecting member 40, and the bracket 20 is electrically connected with the first seat cross member 31 and the second seat cross member 32 through the first connecting member 40.

Specifically, the number of the first connecting members 40 is plural, and a part of the first connecting members 40 passes through the bracket 20 and then is connected to the first seat cross member 31, and fixes the two. Another portion of the first connecting member 40 passes through the bracket 20 and is connected to the second seat cross member 32, and fixes the two. When a plurality of first connecting members 40 are used, stability and reliability of the bracket 20 connected to the vehicle frame 30 are enhanced. On the other hand, the conductivity between the bracket 20 and the frame 30 can be enhanced, and the grounding effect between the bracket 20 and the frame 30 can be improved.

As can be seen from the above description, when the controller 10 provided in the embodiment of the present application performs grounding, the grounding of the controller 10 is achieved by the fixed connection and the conductive connection of the controller 10 and the bracket 20, and the fixed connection and the conductive connection of the bracket 20 and the vehicle frame 30.

As an alternative, when the bracket 20 is fixedly connected to the housing of the controller 10 through the second connector 50, the first connector 40 and the second connector 50 are arranged in a staggered manner. That is, the first connecting member 40 and the second connecting member 50 are disposed at different positions of the bracket 20, and a certain gap is formed between the first connecting member 40 and the second connecting member 50, so that the structural strength of the bracket 20 is ensured by the staggered arrangement of the first connecting member 40 and the second connecting member 50.

As can be seen from the above description, the frame assembly provided in the embodiment of the present application supports the controller 10 by using the bracket 20, and fixes and electrically connects the controller 10 and the frame 30 by using the connecting members such as the bracket 20 and the first connecting member 40 as the electrically conductive connecting members.
