[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0020] The following is for reference. Figures 1-2 The present invention describes a fixing device 1 for a thrust rod according to an embodiment of the present invention. The fixing device 1 can be used to fix and install a thrust rod, and the fixing device 1 for the thrust rod can be installed in a vehicle.

[0021] According to the first aspect embodiment of the present invention, the fixing device 1 for the thrust rod, such as Figure 1 and Figure 2 As shown, the fixing device 1 for the thrust rod may include: a fixed base 10 and a plurality of first mounting parts 20. The fixed base 10 and the plurality of first mounting parts 20 are fixedly connected. Along the height direction of the fixing device 1, the plurality of first mounting parts 20 are all located above the fixed base 10. The plurality of first mounting parts 20 are arranged opposite to each other and spaced apart along a first direction. Along a second direction, one side of the first mounting part 20 has a first inclined sidewall 21. From the first mounting part 20 to the fixed base 10, the first inclined sidewall 21 is inclined to the outside of the first mounting part 20. The first inclined sidewall 21 is used to assemble with the thrust rod. The first direction, the second direction and the height direction of the fixing device 1 are perpendicular.

[0022] It should be noted that as the integration of electric drive axles in existing vehicles increases, the space occupied by the electric drive axles increases, which reduces the available space for the mounting devices and thrust rods, affecting the arrangement of the mounting devices and thrust rods on the vehicle, and making it inconvenient for workers to install the thrust rods.

[0023] Based on this, this application provides a fixing device 1 for a thrust rod. The fixing device 1 can be used to fix and install a thrust rod, which can be a V-shaped thrust rod. The fixing device 1 may include a fixing base 10 and a plurality of first mounting parts 20. The fixing base 10 is adapted to be assembled with the electric drive axle of a vehicle. The fixing base 10 can be connected to the electric drive axle by bolts, thereby allowing the fixing device 1 to be installed on the electric drive axle. Along the height direction of the fixing device 1, the plurality of first mounting parts 20 can all be located above the fixing base 10. When the fixing device 1 is as follows... Figure 2 When setting the direction, the height direction of fixing device 1 is as follows: Figure 2 In the Z-direction, when the fixing device 1 is installed on a vehicle, the height direction of the fixing device 1 can be parallel to the height direction of the vehicle. Multiple first mounting portions 20 can be arranged opposite each other along a first direction, and the multiple first mounting portions 20 can be spaced apart along the first direction. The first mounting portions 20 can be used to mate with a push rod, and at least a portion of the push rod can be located between two adjacent first mounting portions 20. When the fixing device 1... Figure 1 When setting the direction, the first direction can be... Figure 1 In the Y direction, the first direction is perpendicular to the height direction of the fixing device 1. When the fixing device 1 is installed on a vehicle, the first direction can be parallel to the width direction of the vehicle.

[0024] Along the second direction, one side of the first mounting portion 20 may have a first inclined sidewall 21. From the first mounting portion 20 to the fixed base 10, the first inclined sidewall 21 may be inclined outwards from the first mounting portion 20; that is, from the first mounting portion 20 to the fixed base 10, the distance between the first inclined sidewall 21 and another sidewall of the first mounting portion 20 along the second direction gradually increases. It should be noted that, along the second direction, the side of one sidewall of the first mounting portion 20 that faces away from the other sidewall is the outer side of the first mounting portion 20. When the fixing device 1... Figure 1 When setting the direction, the second direction can be... Figure 1 The X-direction, the first direction, the second direction, and the height direction of the fixing device 1 are perpendicular. When the fixing device 1 is installed in a vehicle, the second direction can be parallel to the length direction of the vehicle. When the fixing device 1 is installed in a vehicle, the first inclined sidewall 21 can be located on the side of the first mounting part 20 away from other electrical components on the electric drive axle.

[0025] The first inclined sidewall 21 can be used to assemble with the thrust rod. The first inclined sidewall 21 can be used to support the thrust rod, which helps to improve the reliability and stability of the thrust rod installation. Moreover, by setting the first inclined sidewall 21 to be inclined to the outside of the first mounting part 20, the connection between the thrust rod and the fixing device 1 can avoid other parts on the vehicle, making the arrangement of the thrust rod and the fixing device 1 for the thrust rod reasonable. When the worker installs the thrust rod on the first inclined sidewall 21, the inclined first inclined sidewall 21 makes it easier for the worker to apply force to install the thrust rod on the first mounting part 20, which helps to improve the convenience of the thrust rod installation.

[0026] As an example, one end of the thrust rod along the length of the vehicle can be connected to the electric drive axle via the fixing device 1, and the other end of the thrust rod along the length of the vehicle can be connected to the body or frame. The driving force output by the motor of the electric drive axle or the counter torque during braking can be transmitted to the body or frame through the thrust rod. Furthermore, the thrust rod can work in conjunction with the suspension system to reduce the impact of road bumps on the electric drive axle, thereby achieving the effect of smoothly transmitting force to the body and reducing vehicle vibration.

[0027] In some embodiments of this utility model, such as Figure 2 As shown, the angle between the first inclined sidewall 21 and the height direction of the fixing device 1 is α, which satisfies the relationship: 40°≤α≤50°.

[0028] The first inclined sidewall 21 can form an angle with the height direction of the fixing device 1. For example, the angle between the first inclined sidewall 21 and the height direction of the fixing device 1 can be 40°, 42°, 45°, 48°, 50°, etc. The angle between the first inclined sidewall 21 and the height direction of the fixing device 1 can be within the range of 45° to 50°, including any value including the endpoint value. If the angle between the first inclined sidewall 21 and the height direction of the fixing device 1 is less than 45°, it affects the stability and reliability of the push rod when installed on the first inclined sidewall 21, and it is inconvenient for workers to install the push rod. If the angle between the first inclined sidewall 21 and the height direction of the fixing device 1 is greater than 50°, it increases the contact area between the first mounting part 20 and the fixed base 10, increasing the volume of the fixing device 1 and affecting the rationality of the position of the fixing device 1 and the push rod on the vehicle. Therefore, the angle between the first inclined sidewall 21 and the fixing device 1 in the height direction is between 45° and 50°, which is beneficial to improve the stability and reliability of the thrust rod during installation, and facilitates the installation of the thrust rod by workers. It can also make the arrangement of the thrust rod and the fixing device 1 for the thrust rod more reasonable, which is beneficial to make the thrust rod avoid other parts on the vehicle.

[0029] In some embodiments of this utility model, such as Figure 1As shown, the first inclined sidewall 21 has a mounting hole 211 for mounting fasteners that pass through the thrust rod.

[0030] The first inclined sidewall 21 can be formed with a mounting hole 211, which can penetrate the first inclined sidewall 21 along its thickness direction. When a fastener is inserted into the thrust rod and mates with the mounting hole 211, the fastener can confine the thrust rod within the first inclined sidewall 21, thereby achieving the effect of mounting the thrust rod in the first mounting part 20. This helps to further improve the reliability and stability of the thrust rod during installation. As an example, the mounting hole 211 can be formed with an internal thread, and the fastener can be formed with an external thread. The internal thread can mate with the external thread, allowing the fastener to be assembled in the mounting hole 211. By setting the first inclined sidewall 21 to have a mounting hole 211 with an internal thread, it is beneficial to reduce the use of nuts, reduce the cost of the fixing device 1, reduce the installation difficulty of the thrust rod, and further improve the convenience of the thrust rod installation.

[0031] As an example, the thrust rod can be a V-shaped thrust rod, which can have a pin extending along a first direction. The V-shaped thrust rod is assembled to the first inclined sidewall 21 via the pin, and can be assembled with two first mounting portions 20. Both ends of the pin along the first direction can be assembled with the first mounting portion 20, and two fasteners can be respectively inserted through both ends of the pin along the first direction and assembled with the mounting holes 211 of the corresponding first mounting portions 20, thereby achieving the effect of mounting the V-shaped thrust rod on the first mounting portion 20.

[0032] In some embodiments of this utility model, such as Figure 1 As shown, a limiting protrusion 30 is provided on the first inclined sidewall 21, and the limiting protrusion 30 is located below the mounting hole 211.

[0033] A limiting protrusion 30 may be provided on the first inclined sidewall 21. The limiting protrusion 30 may protrude from the first inclined sidewall 21 and may be located below the mounting hole 211. When the thrust rod and the first inclined sidewall 21 are assembled together, the limiting protrusion 30 can be used to support at least a portion of the thrust rod, which helps to reduce the probability of the thrust rod moving downward along the height direction of the vehicle. When the vehicle is traveling on a bumpy road, it helps to reduce the impact force transmitted by the total weight of the vehicle and the cargo on the vehicle to the electric drive axle, which helps to further reduce vehicle vibration. Moreover, by setting the limiting protrusion 30 below the mounting hole 211, the limiting protrusion 30 will not hinder the worker from installing the thrust rod, which helps to further improve the convenience of thrust rod installation.

[0034] In some embodiments of this utility model, such as Figure 1As shown, along the second direction, the surface of the limiting protrusion 30 near the first inclined sidewall 21 is the first plane 31, and the first plane 31 and the first inclined sidewall 21 are bent and connected.

[0035] Along the second direction, the surface of the limiting protrusion 30 near the first inclined sidewall 21 can be a first plane 31. The first plane 31 can support the thrust rod, which helps to increase the contact area between the limiting protrusion 30 and the thrust rod, improves the stability of the limiting protrusion 30 when supporting the thrust rod, and further reduces the probability of the thrust rod moving downward along the height direction of the vehicle. The first plane 31 can be bent and connected to the first inclined sidewall 21, which is inclined outward towards the first mounting part 20. The first plane 31 can form an angle with the first inclined sidewall 21, which can be an obtuse angle. When the thrust rod is installed in the first mounting part 20, the thrust rod can contact the first inclined sidewall 21 and the first plane 31 respectively. The thrust rod can be limited by contact with the first plane 31, and the first plane 31 will not hinder the worker from installing the thrust rod, which helps to further improve the convenience of the thrust rod installation.

[0036] In some embodiments of this utility model, the first plane 31 is parallel to the upper surface of the fixed base 10.

[0037] The first plane 31 can be parallel to the upper surface of the fixed base 10, which helps to further improve the stability of the limiting protrusion 30 when supporting the thrust rod, helps to further reduce the probability of the thrust rod moving downward along the height direction of the vehicle, and helps to make the first plane 31 bear force evenly, which helps to reduce the stress concentration phenomenon on the limiting protrusion 30.

[0038] In some embodiments of this utility model, such as Figure 1 As shown, the fixing device 1 may further include: a reinforcing rib 40, which is located above the fixing base 10 and fixed to the fixing base 10, and at least one first mounting part 20 is connected to the reinforcing rib 40.

[0039] The reinforcing rib 40 can be located above the fixed base 10, and can be welded to the fixed base 10 or integrally formed with it. At least one first mounting part 20 can be connected to the reinforcing rib 40. The reinforcing rib 40 can improve the connection strength between the corresponding first mounting part 20 and the fixed base 10, and can also improve the structural strength of the fixing device 1, thereby improving the reliability of the fastener and mounting hole 211 during assembly. As an example, there can be two first mounting parts 20 and two reinforcing ribs 40. The two reinforcing ribs 40 can be arranged one-to-one with the two first mounting parts 20, and each first mounting part 20 has a corresponding reinforcing rib 40 connected to it, which improves the connection strength between the first mounting part 20 and the fixed base 10, and also improves the reliability of the thrust rod and the two first mounting parts 20 during assembly.

[0040] According to a second aspect of the present invention, a vehicle includes a thrust rod and a fixing device 1. The fixing device 1 is the same as the fixing device 1 for the thrust rod in the above embodiment. The thrust rod has a second mounting portion, which is opposite to and in contact with a first inclined sidewall 21. Fasteners are inserted through the second mounting portion and fixed to the first mounting portion 20, so that the thrust rod is fixedly mounted on the fixing device 1.

[0041] According to the vehicle of the present application embodiment, the vehicle may include a thrust rod and a fixing device 1 for the thrust rod in the above embodiment. The thrust rod may have a second mounting part (i.e., the pin of the V-shaped thrust rod in the above embodiment). When the thrust rod and the first inclined sidewall 21 are assembled together, the second mounting part may be opposite to and in contact with the first inclined sidewall 21. Fasteners may be inserted into the second mounting part and assembled with the mounting hole 211. The fasteners may be fixedly connected to the first mounting part 20, thereby achieving the effect of mounting the thrust rod on the fixing device 1, which is beneficial to further improve the reliability and stability of the thrust rod during installation.

[0042] In some embodiments of this utility model, the second mounting part is a flat plate structure, and the second mounting part is parallel to the first inclined sidewall 21.

[0043] The second mounting part can be a flat plate structure. The second mounting part can be parallel to the first inclined sidewall 21. That is, the surface of the second mounting part facing the first inclined sidewall 21 can contact and limit the first inclined sidewall 21, which is beneficial to increase the contact area between the second mounting part and the first inclined sidewall 21, and further improves the reliability and stability of the thrust rod during installation.

[0044] In some embodiments of the present invention, the vehicle may further include: a bushing located on the side of the second mounting portion away from the first inclined sidewall 21 and in contact with the second mounting portion, the bushing being used for fasteners to pass through.

[0045] The bushing can be located on the side of the second mounting portion opposite to the first inclined sidewall 21. The fastener can have a head and a shank. The shank of the fastener can pass through the bushing and the second mounting portion and mate with the first mounting portion 20. The bushing can be clamped between the head of the fastener and the second mounting portion, and the bushing can be in contact with and limited by the second mounting portion. The bushing can play a role in vibration damping, which helps to reduce the probability of vibration energy generated by the direct connection between the head of the fastener and the second mounting portion. It helps to achieve the effect of buffering the vibration of the electric drive axle while transmitting drive torque, which helps to further reduce vehicle vibration. It can also help to reduce the friction between the head of the fastener and the second mounting portion, which helps to extend the service life of the fastener and the second mounting portion.
