[0032] A connecting component 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0033] like Figures 1-3 As shown, a connection component 100 according to an embodiment of the present invention is used in a vehicle, the vehicle including a motor 200 and an oil pump, and the connection component 100 includes a connector 1, a buffer 2 and an isolation component 3.

[0034] The connector 1 is adapted to pass through the first mounting hole 2011 of the motor 200 and the second mounting hole 3011 of the oil pump, for connecting the motor 200 and the oil pump. The buffer 2 is sleeved on the connector 1 and is adapted to be located between the motor 200 and the oil pump. Thus, the connection between the motor 200 and the oil pump is achieved through the connector 1, and the vibration transmitted from the motor 200 to the oil pump is absorbed and dispersed by the buffer 2, thereby protecting the normal operation of the oil pump and improving its service life.

[0035] Meanwhile, by fitting the isolation element 3 outside the connector 1 and inside the first mounting hole 2011, during the process of the connector 1 achieving a tight connection between the motor 200 and the oil pump or during the process of the motor 200 transmitting vibration to the oil pump, the isolation element 3 acts as a buffer layer to reduce loosening, wear, and noise caused by the collision between the motor 200 and the connector 1, thereby improving the stability of the overall connection structure of the connector 100, the motor 200, and the oil pump, especially maintaining the tightness and reliability of the connector 1 and the buffering and vibration isolation effect of the buffer element 2 under vibration environment.

[0036] According to the connecting assembly 100 of this utility model embodiment, the connector 1 is adapted to pass through the first mounting hole 2011 of the motor 200 and the second mounting hole 3011 of the oil pump to connect the motor 200 and the oil pump. The buffer 2 is sleeved on the outside of the connector 1 and is adapted to be located between the motor 200 and the oil pump so that the buffer 2 absorbs and disperses the vibration transmitted from the motor 200 to the oil pump, thereby protecting the normal operation of the oil pump and improving the service life of the oil pump. The isolator 3 is sleeved on the outside of the connector 1 and is located in the first mounting hole 2011 to reduce loosening, wear and noise caused by collision between the motor 200 and the connector 1, thereby improving the stability of the overall connection structure of the connecting assembly 100, the motor 200 and the oil pump, especially maintaining the tightness and reliability of the connector 1 and the buffering and vibration isolation effect of the buffer 2 in the vibration environment.

[0037] In some embodiments of this utility model, such as Figures 1-3 As shown, the isolator 3 is made of nylon. It is understood that nylon, as an elastic material, provides good damping characteristics for the isolator 3, thereby further reducing loosening, wear, and noise caused by collisions between the motor 200 and the connector 1. Optionally, the nylon material may be polyhexamethylene adipamide.

[0038] In some embodiments of this utility model, such as Figures 1-3 As shown, the spacer 3 and the connector 1 are clearance-fitted, and the spacer 3 is also clearance-fitted with the inner wall of the first mounting hole 2011. This clearance fit between the spacer 3 and the connector 1 allows for a certain amount of movement between the spacer 3 and the bolt. This enables slight relative movement when subjected to external forces, helping to absorb and mitigate vibrations, further reducing loosening and wear caused by vibrations. Simultaneously, the clearance fit allows for more flexible bolt installation and removal, preventing installation difficulties or damage to parts due to excessive tightness or looseness. This helps reduce maintenance costs and improve work efficiency.

[0039] By using the clearance fit between the spacer 3 and the inner wall surface of the first mounting hole 2011, the direct contact area between the spacer 3 and the inner wall surface of the first mounting hole 2011 is reduced, thereby reducing friction and wear and improving the service life of the spacer 3.

[0040] In some embodiments of this utility model, such as Figures 1-3 As shown, the connector 1 includes a rod 11 and a head 12. The rod 11 is adapted to pass through the first mounting hole 2011 of the motor 200 and the second mounting hole 3011 of the oil pump and is adapted to be connected to the oil pump. The isolator 3 is sleeved on the outside of the rod 11, the buffer 2 is sleeved on the outside of the rod 11, and the head 12 is located on the side of the first mounting hole 2011 away from the second mounting hole 3011. The end of the head 12 near the rod 11 has a flange 121 extending in a direction away from the central axis of the connector 1. The flange 121 is adapted to abut against the motor 200.

[0041] Therefore, the rod 11 is connected to the oil pump, and the flange 121 abuts against the motor 200, so that the connecting piece 1 connects the motor 200 and the oil pump. At the same time, the flange 121 increases the contact area with the motor 200, increasing the friction between the connecting piece 1 and the motor 200, thereby enhancing the connection stability, ensuring that the buffer piece 2 is stably fixed between the motor 200 and the oil pump, and preventing loosening due to torque. This reduces the risk of the buffer piece 2 experiencing excessive vibration and movement, which could lead to wear or cracking of the pad, ensuring the vibration damping effect of the buffer piece 2 and improving overall reliability. In addition, the flange 121 effectively increases the rigidity of the head 12, making it more stable when subjected to vibration or impact, reducing loosening and wear caused by vibration, thereby improving the seismic performance of the entire connection structure.

[0042] In some embodiments of this utility model, such as Figures 1-3 As shown, the flange 121 is an annular shape extending along the circumferential direction of the connector 1. Therefore, the annular flange 121 increases the thickness and rigidity of the head 12, making it more stable under external forces, less prone to deformation or damage, and improving reliability. Simultaneously, the annular flange 121 further increases the contact area between the flange 121 and the motor 200, improving the stability and reliability of the connection.

[0043] In some embodiments of this utility model, such as Figures 1-3 As shown, the rod 11 includes a first section 111 and a second section 112. The first section 111 is located between the flange 121 and the second section 112 and is connected to the flange 121 and the second section 112 respectively. The second section 112 is adapted to be threadedly connected to the inner wall surface of the second mounting hole 3011. The buffer 2 is sleeved on the outside of the first section 111, and the isolation 3 is sleeved on the outside of the first section 111.

[0044] It is understandable that during the process of the rod 11 passing through the first mounting hole 2011 and the second mounting hole 3011 in sequence, since the second section 112 is threadedly connected to the inner wall of the second mounting hole 3011, the motor 200 is moved towards the oil pump by rotating the connecting piece 1, thereby fixing the buffer 2 between the motor 200 and the oil pump. This ensures that the buffer 2 plays the role of isolation, buffering and vibration reduction, effectively reducing the relative movement and vibration between the two supports, further reducing problems such as soft pad wear or cracking caused by excessive vibration movement of the buffer 2, ensuring the vibration reduction and buffering effect of the buffer 2, and improving the overall reliability.

[0045] In some embodiments of this utility model, such as Figures 1-3 As shown, the buffer 2 is a rubber pad. Therefore, the rubber pad has excellent elasticity, enabling it to absorb and disperse vibration energy. When subjected to external impact or vibration, the rubber pad can deform and store energy, releasing it after the impact, thus effectively reducing the vibration transmitted to the oil pump and improving the vibration damping effect. Simultaneously, the rubber pad has high wear resistance and corrosion resistance, allowing for long-term use in harsh environments without easily being damaged, thus extending the service life of the connecting assembly 100.

[0046] In some embodiments of this utility model, such as Figures 1-3 As shown, along the arrangement direction from the first mounting hole 2011 to the second mounting hole 3011, the compression amount of the buffer 2 is 3mm-5mm. It can be understood that by limiting the compression amount of the buffer 2, the buffering and vibration damping effect of the buffer 2 can be accurately controlled. Therefore, by limiting the compression amount of the buffer 2 to 3mm-5mm along the arrangement direction from the first mounting hole 2011 to the second mounting hole 3011, the buffer 2 can effectively absorb and disperse vibration energy, while avoiding performance degradation or damage caused by excessive compression, thus improving overall reliability.

[0047] In some embodiments of this utility model, such as Figures 1-3 As shown, there are multiple connecting components 100, multiple first mounting holes 2011 corresponding to each of the multiple connecting components 100, and multiple second mounting holes 3011 corresponding to each of the multiple connecting components 100. The connector 1 is adapted to pass through the corresponding first mounting hole 2011 and second mounting hole 3011. Thus, the multiple connecting components 100 are used to connect the motor 200 and the oil pump respectively, thereby improving the reliability of the connection between the motor 200 and the oil pump.

[0048] In some embodiments, such as Figures 1-3As shown, the motor 200 includes a first bracket 201 with a first mounting hole 2011, and the oil pump includes a second bracket 301 with a second mounting hole 3011. The connector 1 is used to connect the first bracket 201 and the second bracket 301, thereby connecting the motor 200 and the oil pump.

[0049] In some embodiments, the motor shaft of the motor 200 is an internal spline and the oil pump shaft of the oil pump is an external spline. The combination of the internal and external splines enables the power of the motor 200 to be efficiently transmitted to the oil pump.

[0050] The vehicle according to an embodiment of the present invention is described below.

[0051] The vehicle according to the embodiments of this utility model, such as Figures 1-3 As shown, the device includes a motor 200, an oil pump, and a connecting assembly 100. The motor 200 has a first mounting hole 2011, the oil pump has a second mounting hole 3011, the connecting member 1 passes through the first mounting hole 2011 and the second mounting hole 3011, and the buffer member 2 is located between the motor 200 and the oil pump.

[0052] According to the vehicle of this utility model embodiment, a connecting assembly 100 is provided. A connector 1 passes through the first mounting hole 2011 of the motor 200 and the second mounting hole 3011 of the oil pump to connect the motor 200 and the oil pump. A buffer 2 is sleeved on the outside of the connector 1 and located between the motor 200 and the oil pump so that the buffer 2 absorbs and disperses the vibration transmitted from the motor 200 to the oil pump, thereby protecting the normal operation of the oil pump and improving its service life. An isolator 3 is sleeved on the outside of the connector 1 and located in the first mounting hole 2011 to reduce loosening, wear and noise caused by collision between the motor 200 and the connector 1. This improves the stability of the overall connection structure of the connecting assembly 100, the motor 200 and the oil pump. In particular, it maintains the tightness and reliability of the connector 1 and the buffering and vibration isolation effect of the buffer 2 in a vibration environment, thereby improving the reliability of the vehicle.
