Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to a vehicle and an engine controller bracket thereof. Background Art

[0002] With the development of economy and the increase of environmental protection demand, the environmental performance of vehicles is required to be higher, and the corresponding engine structure and post-processing components are gradually undergoing major functional upgrades and structural optimization. When optimizing and upgrading the structure, it is necessary to add a variety of sensors, actuators, etc., and the hardware structure changes greatly. There is already a problem of limited space resources in the engine body. With the structural changes, more stringent requirements are put forward for the engine and the overall space layout of the vehicle.

[0003] The engine control unit is the core component for realizing engine control and enabling the electronic control functions of the whole vehicle. Based on the higher requirements for the environmental performance of the vehicle, the performance and specifications of the controller have also been improved accordingly. In the related technology, there are two solutions. One is that many engine OEMs adopt the chassis layout engine control unit solution to replace the body layout. The chassis layout engine control unit solution has certain requirements for the overall protection level of the engine controller unit, and has high requirements for waterproof and dustproof, vibration, temperature resistance, maintenance convenience and assembly difficulty. It is technically difficult to avoid problems caused by insufficient protection and requires high production costs; the second is to arrange the engine control unit in the engine body. In this way, the engine body and the attached connectors and cables will occupy a certain space, thereby limiting its internal layout design, and the solution has high requirements for the high temperature resistance and vibration resistance of the controller, resulting in an increase in the cost of controller components and assemblies. Summary of the invention

[0004] Based on this, it is necessary to provide a vehicle and its engine controller bracket which is easy to arrange and has low protection requirements in order to solve the above problems.

[0005] In one aspect, a vehicle engine controller bracket is provided, the bracket being arranged between a cab assembly and a vehicle frame of the vehicle, a suspension assembly being connected between the cab assembly and the vehicle frame, and the bracket comprising:

[0006] A connecting member, disposed on the suspension assembly; and

[0007] A mounting member is provided on the connecting member and is located below the cab assembly. The mounting member is used to mount a controller of the vehicle.

[0008] In one embodiment, the suspension assembly includes a left suspension and a right suspension respectively connected to both sides of the cab, and one end of the connecting member is connected to the left suspension, and the other end is connected to the right suspension.

[0009] In one embodiment, the connecting member is spaced apart from the cab assembly, and / or the connecting member is spaced apart from the vehicle frame.

[0010] In one of the embodiments, the connecting member and the mounting member are detachably connected.

[0011] In one embodiment, the bracket further includes a first fixing member, the connecting member is provided with a first fixing hole, the mounting member is provided with a positioning hole, and the first fixing member passes through the first fixing hole and the positioning hole to connect the mounting member and the connecting member.

[0012] In one of the embodiments, the bracket further includes a second fixing member, the connecting member is provided with a second fixing hole, and the second fixing member passes through the second fixing hole to connect the connecting member and the suspension assembly.

[0013] In one embodiment, the mounting member includes at least two mounting blocks, each of which is disposed at two ends of the mounting member, and the mounting blocks are used to clamp the controller.

[0014] In one of the embodiments, the bracket further comprises a wire management member disposed on the connecting member, and the wire management member is used to fix the wire harness led out from the controller.

[0015] In one embodiment, the cable management member includes a main body and an extension portion, wherein the main body is detachably connected to the connector and is formed with a cable hole for the cable harness to pass through, and the extension portion protrudes from the main body and extends in a direction away from the mounting member.

[0016] In one aspect, a vehicle is provided, comprising:

[0017] Frame;

[0018] a cab assembly connected to the vehicle frame via a suspension assembly; and

[0019] Such as the bracket described above.

[0020] By setting a bracket between the cab assembly and the frame of the vehicle, and setting the controller under the cab assembly, above the frame or in the space between the frames through the mounting parts of the bracket, it is not necessary to set the controller on the chassis or inside the engine, which effectively saves the chassis layout space and makes full use of the location resources of the whole vehicle; there is no need to do too much protection design for the controller, and it is also convenient for the installation and maintenance of the controller. The bracket realizes the modular design of the layout scheme, which can fully support a variety of vehicle models and series. Because the layout position is under the cab assembly, it has good waterproof and dustproof effects, improves the service life of the engine control unit, and reduces the risk of failure. In addition, the ambient temperature is relatively safe, the shock absorption is strong, and the vibration effect of the layout scheme is weak, which reduces the risk of structural damage caused by resonance and provides good reliability of the vehicle system. The layout scheme of the present application has good assembly processability and maintenance convenience, and provides good compatibility with production and after-sales maintenance scenarios.

[0029] In order to cope with the placement of high-performance controllers, there are two solutions in the relevant technology. One is that many engine OEMs adopt the solution of chassis layout of engine control unit to replace the body layout. The solution of chassis layout of engine control unit has certain requirements on the overall protection level of engine controller unit, and has high requirements on waterproof and dustproof, vibration, temperature resistance, maintenance convenience and assembly difficulty. It has certain technical difficulties and requires high production costs to avoid problems caused by insufficient protection; the second is to arrange the engine control unit in the engine body. In this way, the engine body and the attached connectors and cables will occupy a certain space, thereby limiting its internal layout design. In addition, the solution has high requirements on the high temperature resistance and vibration resistance of the controller, resulting in an increase in the cost of controller components and assemblies.

[0030] Based on the above, see Figure 1 , Figure 1 The schematic diagram of the installation of the vehicle engine controller bracket in one embodiment of the present application is shown. The vehicle engine controller bracket provided in one embodiment of the present application is installed on a vehicle. In this embodiment, the vehicle is a heavy commercial vehicle. The vehicle includes a frame 300, a cab assembly 100 and a suspension assembly 200.

[0031] The frame 300 is the base of the entire vehicle. Most of the vehicle's components and assemblies are fixed in place by the frame 300, such as the engine, transmission, suspension, steering system, cab, cargo box and related control mechanisms. The function of the frame 300 is to support and connect the various components of the vehicle and to bear various loads from inside and outside the vehicle. During the complex and changeable driving process of the vehicle, the assemblies and components fixed on the frame 300 should not interfere with each other. When the vehicle is driving on a rough road, the frame 300 will produce torsional deformation and bending deformation in the longitudinal plane under the action of load; when one side of the wheel encounters an obstacle, the entire frame 300 may be twisted into a diamond shape. These deformations will change the relative positions of the various components installed on the vehicle, thereby affecting its normal operation. Therefore, the frame 300 should also have sufficient strength and appropriate rigidity. At present, there are basically three structural forms of the vehicle frame 300: side beam frame, center beam frame and integrated frame.

[0032] Taking the side beam frame commonly used in heavy commercial vehicles as an example, the frame 300 includes two longitudinal beams arranged at intervals, and the two sides of the cab assembly 100 are assumed to be on the two longitudinal beams. The side beam frame consists of two longitudinal beams located on both sides and a plurality of cross beams, and the longitudinal beams and cross beams are connected to form a solid rigid frame by riveting or welding. The longitudinal beams are usually stamped from low-carbon alloy steel plates, and adopt a groove-shaped section with strong bending resistance. Some are also made into I-shaped or box-shaped sections. Depending on the different models and the requirements of the assembly structure layout, the longitudinal beams can be made into a shape that is bent in the horizontal plane or in the longitudinal vertical plane. Its cross section can be equal or unequal. The cross beam is used to connect the left and right longitudinal beams to ensure the torsional rigidity of the frame and bear a certain longitudinal load, and can also support the main components such as the engine and radiator. Because the side beam frame has strong load-bearing capacity and torsional rigidity, simple structure and low process requirements, it is mostly used in large-load trucks, medium and large buses, and vehicles with very high frame rigidity requirements.

[0033] The suspension assembly 200 refers to a suspension system formed by a shock-absorbing structure, which suspends the cab on the frame 300. The suspension assembly 200 is a general term for a device that absorbs and slows down various swings and vibrations during the driving of the car, connects the frame 300 or the load-bearing body with the axle or the wheel, and plays a role in transmitting power. The suspension assembly 200 on the vehicle is divided into a front suspension assembly 200 and a rear suspension assembly 200, wherein the front suspension assembly 200 refers to a device that connects the front wheel, the front axle and the frame 300 (or the body), and the rear suspension assembly 200 is a device that connects the rear wheel, the rear axle and the frame 300 (or the body). This article introduces the front suspension assembly 200 as an example. The suspension assembly 200 is mainly composed of three parts, namely, an elastic element, a shock absorber and a guide device, which respectively play the role of shock absorption, buffering and guiding, and jointly transmit various forces and moments between the wheel and the frame 300 to control various vibrations of the body. The elastic element is used to elastically connect the frame 300 with the axle, wheel, and cab assembly 100, and bear and transmit loads and mitigate impacts. The shock absorber is used to attenuate vibration and improve riding comfort. The guide device is used to ensure that the relative position change between the wheel and the frame 300 or the body conforms to the law of motion and transmit force and torque.

[0034] Common automobile suspensions are mainly divided into two categories: non-independent suspension and independent suspension. Non-independent suspension refers to the installation of automobile wheels on both sides of the integral axle, and elastic elements suspend the wheels and the axle on both sides together under the frame 300 or the body. When the uneven road surface causes the position of the wheel on one side to change relative to the frame 300 or the body, the wheel on the other side also changes position accordingly. Independent suspension is used with a disconnected axle, and the wheels on both sides are independently suspended under the frame 300 or the body through elastic elements. When the position of the wheel on one side changes relative to the frame 300 or the body, the wheel on the other side is almost unaffected. The suspension assembly 200 of the present application can be either a non-independent suspension or an independent suspension. This embodiment is described using one type of suspension assembly 200 structure as an example.

[0035] The bracket 400 is disposed between the cab assembly 100 and the vehicle frame 300 of the vehicle. The bracket 400 includes a connecting member 410 and a mounting member 420. The connecting member 410 is disposed on the suspension assembly 200. The mounting member 420 is disposed on the connecting member 410 and is located below the cab assembly 100. The mounting member 420 is used to mount the controller 500 of the vehicle.

[0036] By setting a bracket 400 between the vehicle's cab assembly 100 and the frame 300, the controller 500 is set under the cab assembly 100, above the frame 300 or in the space between the frames 300 through the mounting member 420 of the bracket 400. It is unnecessary to set the controller 500 on the chassis or inside the engine, thereby effectively saving chassis layout space and making full use of the vehicle's location resources. There is no need to do too much protection design for the controller 500, which is also convenient for the installation and maintenance of the controller 500.

[0037] Furthermore, the bracket 400 realizes a modular design of the layout scheme, which can fully support a variety of vehicle models and series. Since the layout position is under the cab assembly 100, it has good waterproof and dustproof effects, improves the service life of the engine control unit, and reduces the risk of failure. In addition, the ambient temperature is relatively safe, the shock absorption is strong, and the vibration effect of the layout scheme is weak, which reduces the risk of structural damage caused by resonance and provides good reliability of the vehicle system. The layout scheme of the present application has good assembly processability and maintenance convenience, and provides good compatibility with production and after-sales maintenance scenarios.

[0038] In one embodiment, the suspension assembly 200 includes a left suspension 210 and a right suspension 220 respectively connected to both sides of the cab, and one end of the connecting member 410 is connected to the left suspension 210, and the other end is connected to the right suspension 220. Figure 1As shown, the connecting member 410 is arranged on the suspension assembly 200 and moves with the suspension assembly 200. There is no need to set an additional shock-absorbing structure for the controller 500. The controller 500 can use the shock-absorbing function of the suspension assembly 200 to maintain its own stability. The controller 500 and the bracket 300 arranged with the above structure have strong shock-absorbing properties, and the vibration effect of the arrangement scheme is weak, which can reduce the risk of structural damage caused by resonance and provide good reliability of the vehicle system.

[0039] One end of the left suspension 210 and the right suspension 220 are respectively connected to the two longitudinal beams of the frame 300, and the other ends are respectively connected to the two sides of the cab assembly 100. The two longitudinal beams of the frame 300 extend along the longitudinal direction of the vehicle, and the left suspension 210 and the right suspension 220 are symmetrically arranged relative to the longitudinal direction. When the connecting member 410 is connected between the left suspension 210 and the right suspension 220, the extending direction of the connecting member 410 is substantially perpendicular to the longitudinal beams.

[0040] Furthermore, the left suspension 210 and the right suspension 220 are respectively provided with inclined guide arms on the inner side, and both ends of the connecting member 410 are connected to the inclined guide arms. Both ends of the connecting member 410 are provided with inclined cutouts matching the guide arms.

[0041] In one embodiment, the connecting member 410 is spaced apart from the cab assembly 100, and / or the connecting member 410 is spaced apart from the frame 300. Specifically, the connecting member 410 is spaced apart below the cab assembly 100 and above the frame 300. In other embodiments, the connecting member 410 may also be at least partially (especially the mounting member 420) located between the longitudinal beams of the frame 300.

The bracket 400 also includes a first fixing member, the connection member 410 is provided with a first fixing hole 411, and the mounting member 420 is provided with a positioning hole (not shown in the figure), and the first fixing member passes through the first fixing hole 411 and the positioning hole to connect the mounting member 420 and the connection member 410. Specifically, at least two first fixing holes 411 are provided, and at least two positioning holes are also provided. The number of first fixing holes 411 can be greater than the number of positioning holes, so as to adjust the position of the mounting member 420.

The second fixing hole 412 is provided at the end of the connecting member 410, especially at the inclined cutout. The adapting hole is located in the middle of the guide wall, so that the connecting member 410 is arranged in the middle of the suspension assembly 200, so that the controller 500 is arranged at least at a certain interval from the cab assembly 100. Preferably, the second fixing member is a combination structure of a bolt and a nut.

[0044] In one embodiment, the mounting member 420 includes at least two mounting blocks 421, each of which is disposed at both ends of the mounting member 420, and the mounting blocks 421 are used to clamp the controller 500. Specifically, the width of the mounting member 420 in the up-down direction is greater than the width of the connecting member 410, so that the mounting member 420 is respectively protruded above and / or below the connecting member 410, and at least two mounting blocks 421 are disposed at each end of the connecting member 410 in the up-down direction (or parallel to the longitudinal direction of the connecting member 410), and the controller 500 can be clamped between the mounting block 421 at the upper end and the mounting block 421 at the lower end. Further, the mounting member 420 is rectangular, and the four ends of the rectangle are provided with mounting blocks 421.

[0045] like Figure 2 As shown, the mounting member 420 includes a bending portion 423 and a supporting portion 422. The bending portion 423 is recessed toward the connecting member 410. The supporting portion 422 is parallel to the connecting member 410 and extends downward and upward from the bending portion 423. In the vertical direction, the supporting portion 422 protrudes from the connecting member 410. The controller 500 mounted on the mounting member 420 is fitted against the supporting portion 422. Due to the recess, the bending portion 423 is spaced apart from the controller 500. A positioning hole is provided on the bending portion 423 to facilitate the first fixing member to pass through.

[0046] In one embodiment, the bracket 400 further includes a wire management member 430 disposed on the connector 410, and the wire management member 430 is used to fix the wire harness led out from the controller 500.
