[0029] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0030] Reference below Figure 1-Figure 4 A hybrid electric drive assembly 1 according to an embodiment of the present utility model is described.

[0031] like Figure 1 As shown, the hybrid electric drive assembly 1 according to the embodiment of the utility model includes: a housing 10, a transmission shaft assembly 20 and a P gear assembly 30. The housing 10 is an important component of the hybrid electric drive assembly 1, which can be used for installation and to protect the internal structure of the hybrid electric drive assembly 1. The transmission shaft assembly 20 can mainly play a role in transmitting power, and the P gear assembly 30 can mainly complete the parking motion of the locked vehicle to prevent safety accidents.

[0032] like Figure 1As shown, the transmission shaft assembly 20 is disposed in the housing 10, the P gear assembly 30 is at least partially disposed in the housing 10, and the P gear assembly 30 selectively locks the transmission shaft assembly 20. The transmission shaft assembly 20 is disposed in the housing 10, and the P gear assembly 30 is also at least partially disposed in the housing 10, so that the housing 10 can protect the transmission shaft assembly 20 and the P gear assembly 30 to prevent the transmission shaft assembly 20 and the P gear assembly 30 from being damaged, and in this way, the external environment can also be prevented from affecting the normal operation of the transmission shaft assembly 20 and the P gear assembly 30.

[0033] In addition, the P gear assembly 30 selectively locks the transmission shaft assembly 20, that is, the P gear assembly 30 can lock the transmission shaft assembly 20, at which time the transmission shaft assembly 20 cannot transmit power, and the P gear assembly 30 can also not lock the transmission shaft assembly 20, at which time the transmission shaft assembly 20 works normally. When the vehicle is parked, the P gear assembly 30 locks the transmission shaft assembly 20, the transmission shaft assembly 20 stops working, and cannot transmit power to the vehicle. In this way, the parking function of the vehicle can be completed and safety accidents can be prevented. Of course, when the vehicle starts, the P gear assembly 30 unlocks the transmission shaft assembly 20, and the vehicle moves normally. It should be noted that the P gear assembly 30 can be connected to the housing 10 and the transmission shaft assembly 20 by bolts, splines, etc.

[0034] Therefore, by providing the P gear assembly 30, the P gear assembly 30 can lock the drive shaft assembly 20, complete the parking movement of the locked vehicle, and prevent safety accidents. In addition, the P gear assembly 30 has a simple structure, and at least part of the P gear assembly 30 can be set in the shell 10 with limited space, so that the space occupied is small, which can solve the space layout problem of the hybrid electric drive assembly 1 and reduce production costs.

[0035] Specifically, Figure 1 As shown, the transmission shaft assembly 20 includes: an input shaft assembly 200 and an output shaft assembly 201, the input shaft assembly 200 and the output shaft assembly 201 are in driving cooperation, and the P gear assembly 30 selectively locks the input shaft assembly 200.

Of course, the P gear assembly 30 can also selectively lock the output shaft assembly 201.

[0036] Among them, Figure 1 As shown, the input shaft assembly 200 includes: a first clamping member 202, and the P gear assembly 30 includes: a second clamping member 300, and the second clamping member 300 is selectively clamped and matched with the first clamping member 202. The first clamping member 202 and the second clamping member 300 can both play a clamping role, and the second clamping member 300 is selectively clamped and matched with the first clamping member 202, so that the input shaft assembly 200 and the P gear assembly 30 can be locked and matched by the clamping of the first clamping member 202 and the second clamping member 300, so as to achieve the parking of the vehicle. Among them, the clamping method is simple and convenient to operate, and can make the connection between the input shaft assembly 200 and the P gear assembly 30 more firm and reliable.

[0037] In addition, if Figure 1 As shown, the first clamping member 202 is configured as a ratchet structure, and the second clamping member 300 is configured as a pawl structure. That is, when the vehicle gear is changed to the P gear, the pawl structure selectively engages with the ratchet structure to complete the parking movement of the locked vehicle. When the vehicle gear is not in the P gear, the pawl structure releases the ratchet structure, that is, the second clamping member 300 releases the first clamping member 202, so that the vehicle can drive normally. The structure of the ratchet and the pawl is simple, easy to install and manufacture, and the cooperation between the ratchet and the pawl is more reliable and effective.

The first transmission member 301 and the second transmission member 302 are matched in transmission, so that the first transmission member 301 can drive the second transmission member 302 to move, and the second transmission member 302 is connected to the connecting member 303, so that the second transmission member 302 and the connecting member 303 form a whole, and the connecting member 303 can move with the second transmission member 302, and the second clamping member 300 is connected to the connecting member 303, so that the second clamping member 300 can move with the connecting member 303, so that the second clamping member 300 can move to the first clamping member 202, and be clamped with the first clamping member 202, and can also be moved away from the first clamping member 202 to release the clamping cooperation with the first clamping member 202.

[0039] Furthermore, if Figure 2As shown, the first transmission member 301 is constructed as a cylindrical gear, and the second transmission member 302 is constructed as an end gear. The first transmission member 301 is constructed as a cylindrical gear, which is a common type of gear and is widely used in various mechanical and industrial fields. It can transmit motion or change the direction of motion, reduce rotation speed or increase torque, improve transmission efficiency, and adapt to different industrial requirements. The second transmission member 302 is constructed as an end gear, which can transmit power and motion, change rotation speed and torque, change rotation direction, realize long-distance transmission, provide smooth transmission and buffer shock absorption, realize precise transmission and realize various forms of motion.

[0040] It should be noted that if Figure 2 As shown, the rotation axis of the cylindrical gear extends along the first direction, the rotation axis of the end gear extends along the second direction, and the first direction is perpendicular to the second direction. The rotation axis of the cylindrical gear extends along the first direction, and the rotation axis of the end gear extends along the second direction, that is, the extension direction of the rotation axis of the first transmission member 301 and the extension direction of the rotation axis of the second transmission member 302 are perpendicular to each other, that is, the first transmission member 301 and the second transmission member 302 are arranged vertically, so that the power transmission direction can be changed, the space in the housing 10 is reasonably used, and the space occupation of the P gear assembly 30 is reduced.

[0041] In addition, if Figure 2 As shown, the P gear assembly 30 also includes: a controller 304, which is arranged on the outside of the housing 10, and the controller 304 is electrically connected to the first transmission member 301.

The controller 304 is arranged on the outside of the housing 10, and the housing 10 can realize the installation and fixation of the controller 304. It should be noted that the controller 304 can be fixed to the housing 10 by bolts on the housing 10. The controller 304 is electrically connected to the first transmission member 301. At this time, the controller 304 electrically controls the first transmission member 301, and the controller 304 can provide power to the first transmission member 301, so that the transmission of the first transmission member 301 can be realized.

[0042] Alternatively, if Figure 1 and Figure 2As shown, the P gear assembly 30 also includes: a heat shield 305, the heat shield 305 is arranged on the outside of the shell 10, and the heat shield 305 is covered on the controller 304. The heat shield 305 can mainly prevent heat loss, reduce temperature, reduce fuel consumption, increase safety and heat insulation. It should be noted that the controller 304 is generally arranged near the exhaust pipe of the vehicle, and the temperature at the exhaust pipe is relatively high. The heat shield 305 is arranged on the outside of the shell 10, and the heat shield 305 is covered on the controller 304. At this time, the heat shield 305 can avoid the risk of heat damage caused by the exhaust pipe, ensure the safety of the controller 304, and thus ensure the normal operation of the controller 304. Among them, the heat shield 305 can be made of embossed aluminum material.

[0043] In addition, Figure 2 As shown, the controller 304 is provided with a first mounting hole 306, the heat shield 305 is provided with a second mounting hole 307, and the fastener is fixed to the housing 10 through the first mounting hole 306 and the second mounting hole 307. For example, the first mounting hole 306 and the second mounting hole 307 can both be threaded holes, and the fastener can be a stud, which is then fixed in the first mounting hole 306 and the second mounting hole 307, so that the fastener can be fixed to the housing 10. In this way, the controller 304 and the heat shield 305 are connected and fixed by a common fastener, and the structure is compact at this time, and the risk of heat damage caused by the exhaust pipe can be well prevented without affecting the spatial arrangement.

The first clamping member 202 is connected to the linkage member 204. The first clamping member 202 can move with the rotation of the linkage member 204. When the vehicle gear is changed to the P gear, the first clamping member 202 is engaged with the second clamping member 300. At this time, the first clamping member 202 will also clamp the linkage member 204. The linkage member 204 drives the input member 203 to stop rotating, thereby stopping the power transmission and completing the parking movement of locking the vehicle. When the vehicle gear is not in the P gear, the second clamping member 300 releases the first clamping member 202, allowing the vehicle to drive normally.

[0045] In addition, if Figure 3 As shown, the input shaft assembly 200 further includes: a sleeve 206, which is disposed between the first clamping member 202 and the linkage member 204. The sleeve 206 can mainly play the role of positioning and protection.
