Description

TECHNICAL FIELD

[0001] The present application relates to a fixing device, in particular to a fixing device for a vehicle. BACKGROUND

[0002] The communication controller is a necessary accessory of the vehicle at present, which needs to be fixed on the vehicle.

[0003] The fixing mode of the existing controller focuses on the fixing of the controller itself, and after installation, the controller cannot be disassembled and reassembled, which is not conducive to the subsequent maintenance of the controller.

[0004] In addition, the general controller fixing structure does not consider the electromagnetic compatibility problem. If the wire harness is arranged on the fixing part, EMC problem will be caused. If it is fixed in other areas, the internal space of the vehicle body is occupied, the structure needs to be changed, the length of the wire harness is long, and additional EMC calibration experiment needs to be carried out.

[0005] In addition, the fixing structure of the existing controller support is not replaceable, so there is a great limitation in cross-model arrangement.

[0006] For example, the Chinese patent document with publication number CN217145658U and publication date August 9, 2022, named "Motor controller support structure" discloses a motor controller support which can simultaneously install two components of motor controller and electronic control unit, reducing the total number of supports of the vehicle, but it cannot realize the disassembly and assembly of the motor controller. SUMMARY

[0007] One of the purposes of the present application is to provide a combined fixing device for a vehicle-mounted communication controller, which can realize the convenient disassembly and assembly of the vehicle-mounted communication controller without damaging the combined fixing device itself, and the vehicle-mounted communication controller will not fall out when the vehicle collides, thereby facilitating the maintenance and inspection of the controller.

[0023] Further, in the combined fixing device of the vehicle-mounted communication controller, the mounting clamp has an elastic wing part, and the elastic wing part is correspondingly arranged in the clamping groove of the fixing base.

[0024] Further, in the combined fixing device of the vehicle-mounted communication controller, the side edge of the fixing base is provided with a wire harness clamp for arranging the wire harness of the vehicle-mounted communication controller.

[0025] In the embodiment of the present application, the setting of the clamping hoop solves the wiring problem of the harness of the vehicle-mounted communication controller. If the wiring of the subsequent vehicle model is needed, the structure can be directly used, and EMC (electromagnetic compatibility) rechecking is not needed.

[0044] The combined fixing device of the vehicle communication controller of the present invention will be further explained and described below with reference to the accompanying drawings and specific embodiments. However, such explanation and description do not constitute an improper limitation on the technical solution of the present invention.

[0045] Figure 1 This diagram shows a fixed-side view of the combined fixing device for the vehicle communication controller according to one embodiment of the present invention.

[0046] like Figure 1 As shown, in some embodiments, the combined fixing device of the vehicle communication controller includes: a fixing base 100 having a fixing side (or "front") and a mounting side (or "back"), the fixing base having a plurality of honeycomb holes 105. A baffle 102 protrudes in the height direction (i.e., in the Z-direction). A Y-direction limiting plate 101 is disposed on the fixing base 100 and rotatably connected thereto, for opening and closing relative to the fixing base. A plurality of spring tabs 103, for example, four spring tabs 103 are disposed on the fixing side of the fixing base 100. A plurality of Z-direction limiting ribs 104, for example, six, are disposed on the side wall of the fixing side of the fixing base.

[0047] Figure 2The figure shows the schematic diagram of the installation of the vehicle communication controller to the combined fixing device of the vehicle communication controller in one embodiment.

[0048] The installation process of the vehicle communication controller 200 to the combined fixing device is shown in Figure 2 The Y direction limiting plate 101 is opened relative to the fixing base 100, the back of the vehicle communication controller 200 is pushed against the combined fixing device from left to right until it is stopped by the stop plate 102. At this time, the elastic sheet 103 exerts the elastic force in Z direction upwards to the vehicle communication controller 200, so that the vehicle communication controller 200 is stopped against the Z direction limiting rib 104. The Z direction fixing is completed by the normal pressure as shown in Figure 5 Then, the Y direction limiting plate 101 is closed relative to the fixing base, and the Y direction limiting plate 101 and the stop plate 102 limit the vehicle communication controller installed on the fixing base in Y direction.

[0049] In this way, the vehicle communication controller can still work when the collision occurs. In the prior art, in order to avoid the vehicle communication controller from being detached from the bracket during the collision, the controller cannot be disassembled after being fixed on the vehicle.

[0050] Figure 3 The partial enlarged view of the part J in Figure 2

[0051] As shown in Figure 3 The Y direction limiting plate 101 is further provided with the stop sheet 1011 protruding in the height direction, which further limits the vehicle communication controller in Y direction. In addition, the Y direction limiting plate is provided with the honeycomb hole 1012, which helps the further heat dissipation of the vehicle communication controller.

[0052] Figure 4 The sectional view of the part A-A in Figure 1

[0053] As shown in Figure 4 In one embodiment, the elastic sheet 103 is an arch-shaped flexible sheet, which deforms when it is pressed, and the elastic force generated by the deformation of the elastic sheet 103 exerts the pressure to the vehicle communication controller.

[0054] In the present application, the Y direction limiting plate 101 can be connected to the fixing base in a rotatable manner through various forms. Figure 6 The connection form of the Y direction limiting plate to the fixing base in one embodiment of the present application is shown schematically.

[0055] As shown in Figure 6 ​​As shown, this embodiment adopts a simple connection method, which does not use a hinge shaft, but uses an intermediate transition plastic connector 106 to realize the rotatable connection between the Y-direction limiting plate 101 and the fixed base 100.

[0056] Figure 7 The diagram schematically illustrates the closed state of the Y-axis limiting plate and the fixed base in one embodiment of the present invention.

[0057] After the vehicle communication controller is pushed into place and presses against the baffle 102 of the combined fixing device, the Y-direction limiting plate 101 can be closed. For example... Figure 7 As shown, in some embodiments, the Y-direction limiting plate 101 can be implemented by a slot 1013 and a buckle provided thereon and on the fixed base.

[0058] Figure 8 This diagram shows a schematic view from the installation side of the combined mounting device for the vehicle communication controller described in this invention, in one embodiment.

[0059] like Figure 8 As shown, in some embodiments, the mounting side of the fixed base 100 is provided with a plurality of mounting clamps 107 for connection to a vehicle. In addition, the mounting side of the fixed base 100 is also provided with a plurality of wedge-shaped guides 108 extending in the height direction.

[0060] After fixing the vehicle communication controller to this mounting assembly, it can be fixed together with the mounting assembly to the vehicle body sheet metal. Using the wedge-shaped guide 108, the installation position of the mounting assembly can be quickly located on the vehicle body sheet metal. Then, the mounting clips 107 are directly snapped into the corresponding holes on the vehicle body sheet metal bracket, thus completing the fixing of the mounting assembly P and the controller to the vehicle body sheet metal Q. Figure 9 As shown.

[0061] In a preferred embodiment, the mounting clamp is designed to be replaceable, thereby allowing for the selection and replacement of appropriate mounting clamps based on the different fixing positions and sheet metal thicknesses of each vehicle model, thus meeting the fixing requirements of most vehicle models.

[0062] Figure 10 The illustration schematically shows the state in which the mounting clamp of the combined fixing device for the vehicle communication controller of the present invention is detachably mounted on the fixing base in one embodiment.

[0063] Figure 11 for Figure 10 Sectional view at point BB.

[0064] Figure 12 for Figure 10 Sectional view at point CC.

[0065] As Figure 10 , Figure 11 and Figure 12 shown, in this embodiment, the mounting clamp 107 has a resilient wing portion 1071, the resilience of which is achieved by, for example, an arc-shaped portion as shown in Figure 12 . When the mounting clamp 107 is inserted into the fixed base as shown in Figure 10 , the resilient wing portion 1071 is correspondingly clamped into the clamping groove of the fixed base. Among them, the Y-direction fixation is achieved by relying on the boss 111 on the fixed base, and the X and Z direction limiting is defined by the structure space of the clamping groove.

[0066] Figure 13 The harness clamp of the combined fixing device of the vehicle-mounted communication controller is schematically shown in an embodiment.

[0067] Continuing to refer to Figure 8 and Figure 13 , in some embodiments, the side of the fixed base 100 is provided with a harness clamp 109 for arranging the harness W of the vehicle-mounted communication controller.

[0068] Thus, the harness connected to the vehicle-mounted communication controller can be clamped into the harness clamp 109 on the side of the combined fixing device. The position of this harness clamp fully considers the requirements of the controller EMC, avoiding the range that may cause EMC problems. Therefore, other vehicle models such as wiring with the clamp of the present combined fixing device neither occupy the surrounding space nor need to perform additional EMC checking.

[0069] In some embodiments, the combined fixing device can be mounted on the vehicle metal panel above the roof trim.
