Description

Technical Field

[0001] The present application relates to the technical field of automobile engine suspension systems, and in particular to a suspension support mechanism for supporting a range extender. Background Art

[0002] The range extender assembly is connected and fixed to the vehicle body through the suspension system. The suspension system supports the range extender assembly. At the same time, the suspension system also limits the displacement of the range extender assembly during vehicle driving to avoid excessive displacement of the range extender assembly and interference with surrounding components.

[0003] Currently, the vehicles on the market are arranged with a three-point torque shaft suspension system. The left and right suspensions are mainly responsible for limiting the range extender assembly. The rear suspension does not bear the weight of the range extender, but is mainly responsible for resisting the reaction force of the output torque of the range extender.

[0004] At present, the full life cycle operating conditions of vehicles can be roughly divided into normal operating conditions, normal extreme operating conditions, misuse conditions, normal collision conditions, etc. according to the severity. Normal operating conditions, normal extreme operating conditions, misuse conditions, and normal collision conditions require that the range extender suspension cannot be damaged. Extreme misuse conditions (such as going over a speed bump at 50km / h and falling into a pothole) allow the range extender to be damaged. Extreme collision conditions such as high-speed head-on collisions do not require the degree of damage to the range extender suspension. In the actual use of the user, for those that meet the conditions of normal misuse conditions, the range extender suspension components may break, fall off, or have their rubber torn off. The left and right suspension systems may be damaged, and the limiting effect on the range extender assembly may fail. The rear suspension cannot support the range extender. If the range extender assembly falls, the range extender will suffer serious damage. Summary of the Invention

[0029] In order to enable those skilled in the art to better understand the technical solution of the present application, the present application is described in detail below with reference to the accompanying drawings. The description in this section is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present application.

[0030] Please refer to Figure 1-Figure 7 This embodiment provides a suspension support mechanism for supporting a range extender, comprising:

[0031] A front subframe assembly 1 is provided with a first space formed in the middle thereof and extending through the front subframe assembly 1 along a second direction; the front subframe assembly 1 further includes:

[0032] A first suspension support member 2 is provided in the first space, and the first suspension support member 2 extends along a first direction; the first direction is perpendicular to the second direction; both ends of the first suspension support member 2 are respectively connected to the front subframe assembly 1;

[0033] The first suspension support member 2 is used to provide a supporting force in a second direction for the range extender.

[0034] Specifically, in this embodiment, a first space is formed in the middle of the front subframe assembly 1, and the first space is penetrated along the second direction, and the second direction is the vertical direction; the first suspension support member 2 is also included, and the first suspension support member 2 is arranged in the first space, and the first suspension support member 2 extends in the first space along the first direction, and the first suspension support member 2 is Figure 1 , the two ends of the first suspension support 2 are respectively connected to the sub-frame assembly, and the sub-frame assembly is similar to the shape of a quadrilateral, and the two ends of the first suspension support 2 are detachably connected to the two corresponding sides of the sub-frame assembly, for example, they can be fixed together by bolts or rivets; the first suspension support 2 is used to provide support force in the second direction for the range extender. When the left suspension and the right suspension are broken, or one of the components is damaged, the range extender will fall, and the existing rear suspension has no supporting effect on the range extender. In this application, the first suspension support 2 is arranged in the first space and spans the first space. When the range extender falls, it will directly fall on the first suspension support 2, which can greatly reduce the damage caused by the range extender when it falls.

[0035] During use, when the left suspension and the right suspension are broken or one of the components is damaged, the range extender will fall. When the range extender falls downward, it will fall directly onto the first suspension support located below the range extender. The first suspension support gives the range extender a vertical upward supporting force, thereby preventing the range extender from suffering major damage after falling.

[0036] Specifically, in this embodiment, a support portion 3 is provided in the middle of the first suspension support member 2. The support portion 3 is cylindrical. The support portion 3 can increase the contact area with the range extender, and can provide better protection for the range extender when the range extender falls.

[0037] Furthermore, the support portion 3 is rotatably provided with a connecting portion 4 extending along the second direction.

[0038] Specifically, in this embodiment, a connecting portion 4 is further provided on the support portion 3, and the connecting portion 4 is rotatably connected to the support portion 3. A through hole is provided at the top of the support portion 3, and the connecting portion 4 extends into the interior of the support portion 3 through the through hole. The connecting portion 4 is cylindrical, and the diameter of the connecting portion 4 is much smaller than the diameter of the support portion 3. The connecting portion 4 extends along the second direction. In this embodiment, the connecting portion 4 is a bolt, and the connecting portion 4 is used to connect to the range extender, and the connecting portion 4 and the range extender are fixedly connected.

[0039] Furthermore, the first suspension support 2 is arranged directly below the center of mass of the range extender.

[0040] Specifically, in this embodiment, the first suspension support member 2 is arranged directly below the center of mass of the range extender. The center of mass of the range extender can be obtained through experiments, which can ensure that when the range extender rotates, the force direction of the first suspension support member 2 is the tangential direction of the bolt.

[0041] Furthermore, a limiting member 8 is provided in the support portion 3, and the limiting member 8 includes a limiting portion 9, one end of the limiting portion 9 contacts the bottom of the support portion 3 to form an accommodating space; an insertion portion 10 is provided on an end of the limiting portion 9 relatively close to the support portion 3, and an end of the connecting portion 4 relatively far from the support portion 3 extends into the accommodating space along the second direction through the insertion portion 10.

[0042] Specifically, in this embodiment, please see Figure 6 , a limiter 8 is further provided inside the support portion 3, and the limiter 8 has a limiter 9. The end of the limiter 9 relatively far away from the support portion 3 contacts the bottom inner wall of the support portion 3 to form an accommodating space, and the end of the limiter 9 relatively close to the support portion 3 is provided with an insertion portion 10, and the insertion portion 10 is in the shape of a circular hole. The end of the connecting portion 4 relatively far away from the support portion 3 extends in the opposite direction along the second direction and extends into the accommodating space. The accommodating space and the insertion portion 10 limit the movement of the range extender by limiting the movement of the connecting portion 4, thereby preventing the range extender from rotating at an excessive angle.

[0043] For ease of description, please see Figure 6 , the limiting member 8 is named in a clockwise direction as the first branch 801, the second branch 802, the third branch 803, the fourth branch 804, the fifth branch 805 and the sixth branch 806, which are connected to each other. The first branch 801 and the fifth branch 805 have the same shape, the second branch 802 and the fourth branch 804 have the same shape, the third branch 803 is arc-shaped, and the opening of the arc-shaped third branch 803 faces the inner wall of the support portion 3. The sixth branch 806 is straight, and both ends of the sixth branch 806 are aligned with the first branch. The places where the first through-hole 901 and the fifth through-hole 805 are connected are further provided with curved connecting parts 807; four holes are opened on the upper surface of the limiting part 9, which are respectively recorded as the first through-hole 901, the second through-hole 902, the third through-hole 903 and the fourth through-hole 904; wherein the first through-hole 901 and the fourth through-hole 904 are symmetrical about the axis of the insertion part 10, and their shapes are similar to triangular holes, and the three corners are designed to be arc-shaped; the second through-hole 902 and the third through-hole 903 are strip holes, and are symmetrical about the axis of the insertion part 10.

[0044] Furthermore, a shockproof member 7 is provided on the periphery of the limiting member 8, and the shockproof member 7 is provided with a first connecting portion and a second connecting portion. The first connecting portion is used to connect with the periphery of the limiting member 8, and the second connecting portion is used to connect with the inner wall of the support portion 3.

[0045] Specifically, in this embodiment, please see Figure 7 The outer periphery of the limiting member 8 is provided with a shockproof member 7, and the shockproof member 7 has a first connecting portion and a second connecting portion. The first connecting portion is connected to the outer wall of the limiting member 8, and the connection therebetween is fixed. The shape of the first connecting portion is adapted to the shape of the outer wall of the limiting member 8, and the second connecting portion is connected to the inner wall of the supporting portion 3. The rubber between the first connecting portion and the second connecting portion (such as Figure 7 The shadow part is shown) and is accumulated in the form of wrinkles in the space formed by the limiting member 8 and the inner wall of the support portion 4. For details on the shape, please see Figure 7The shock-absorbing member 7 is made of rubber. Because the range extender moves during operation, the connecting portion 4 connected to the range extender also moves during the movement. When the range extender rotates left or right, the rotation angle may be too large. For example, when the range extender rotates clockwise, the rubber will be pulled clockwise during the clockwise rotation. The rubber itself has a certain pulling limit. When the rotation angle of the range extender reaches the pulling limit of the rubber, the range extender is forced to stop rotating and drives the rubber to rotate counterclockwise. When the range extender moves upward, it drives the connecting portion 4 upward. At the same time, the limiter 8 fixed to the connecting portion 4 also moves upward, thereby driving the rubber upward. However, because the rubber has a certain pulling limit, the rubber can also limit the amplitude of the upward movement of the range extender. On the other hand, because the rubber itself has a certain elastic force, the rubber can absorb some of the vibration generated by the range extender during operation, reducing the impact on the vehicle body.

[0046] During use, when the range extender rotates, the connecting part will be driven to rotate. At the same time, the rubber connected to the connecting part will be deformed, which can reduce the impact of the vibration generated by the range extender on the vehicle body.

[0047] Furthermore, the first suspension support 2 divides the first space into a first area and a second area; the first area and the second area have the same area.

[0048] Specifically, in this embodiment, the first suspension support member 2 divides the first space into a first area and a second area along the first direction, and the first area and the second area are the same in area and symmetrical.

[0049] Furthermore, a buffer is provided on a surface of the front subframe assembly 1 relatively away from the connecting portion 4 , and the buffer spans the first space.

[0050] Specifically, in this embodiment, a buffer is further provided on the front subframe assembly 1 , and the buffer spans the first space, that is, both ends of the buffer are respectively connected to two sides of the front subframe.

[0051] Furthermore, the buffer component includes a plurality of first buffer belts 5 extending along the first direction, and both ends of the first buffer belts 5 are detachably connected to the front subframe assembly 1 .

[0052] Specifically, in this embodiment, the buffer component includes several first buffer belts 5, which are safety belts. There is one first buffer belt 5, and the two ends of the first buffer belt 5 are respectively connected to the two sides of the front subframe in relative positions, and are detachably connected; when the range extender falls, the first suspension support component 2 cannot support the range extender, and the first buffer belt 5 can provide a vertical upward supporting force for the range extender.

[0053] Furthermore, the buffer component further includes a plurality of second buffer strips 6 , and the second buffer strips 6 are interlaced with the first buffer strips.

[0054] Specifically, in this embodiment, the buffer member also includes several second buffer belts 6, which are safety belts. The number of the second buffer belts 6 is one, and the second buffer belts 6 and the first buffer belts 5 are staggered with each other. The angle between the second buffer belts 6 and the first buffer belts 5 is a right angle, and together with the second buffer belts 6, they constitute a cross-shaped buffer member. When the range extender falls, the first suspension support member 2 will first provide a vertical upward support force. When the first suspension support member 2 is not sufficient to support the range extender, the buffer member will serve as a last guarantee to provide a vertical upward support force for the range extender to prevent damage to the range extender.

[0055] The suspension support mechanism for supporting the range extender provided in the embodiment of the present application will cause the range extender to fall when the left and right suspensions connected to the range extender are damaged, and the first suspension support member located below the center of mass of the range extender will provide vertical support force for the range extender to prevent damage to the range extender. When the first suspension support member is unable to bear the weight of the range extender, the buffer member located on the front subframe can provide a vertical upward support force for the range extender again to prevent major damage to the range extender.

It should be pointed out that due to the limitations of textual expression, there are objectively infinite specific structures. For ordinary technicians in this technical field, without departing from the principles of the present invention, they can also make several improvements, modifications or changes, and can also combine the above technical features in an appropriate manner; these improvements, modifications, changes or combinations, or the direct application of the inventive concept and technical solution to other occasions without improvement, should be regarded as the scope of protection of this application.
