[0035] As described in the background section, existing range extenders typically require the cylinder block to be connected to the motor assembly. The motor stator is first installed on the motor housing to form the motor assembly, and then connected to the cylinder block. Furthermore, the engine assembly and generator assembly in existing range extenders are assembled in different factories, and then transported together for final assembly. Therefore, existing cylinder blocks and motor stators suffer from complex assembly steps, low assembly efficiency, and high assembly costs.

[0036] Please refer to Figure 1 and Figure 2 The integrated cylinder block 100, range extender, and automobile provided in the embodiments of this utility model can solve the above problems, and will be described in detail below.

[0037] In a first aspect, an embodiment of the present invention provides an integrated cylinder block 100 for use in a range extender. The integrated cylinder block 100 includes a cylinder block seat 110, a motor stator 120, and a fastener 130. One end of the cylinder block seat 110 has a mounting boss 111, the mounting boss 111 has a first connecting hole 112, the motor stator 120 has a second connecting hole 121, and the fastener 130 passes through the second connecting hole 121 and is connected to the first connecting hole 112.

[0038] During the assembly process, the cylinder block 110 can contact the motor stator 120 through the mounting boss 111, and then the motor stator 120 and the cylinder block 110 can be connected by fasteners 130, which simplifies the installation steps of the motor stator 120, improves the assembly efficiency, and reduces the assembly cost.

[0039] Please refer to Figure 1 and Figure 2 To ensure assembly stability, the number of mounting bosses 111 and first connecting holes 112 can be multiple, with multiple mounting bosses 111 and first connecting holes 112 spaced apart along the circumference of the cylinder block seat 110.

[0040] Specifically, the cylinder block has seven mounting bosses 111 and seven first connecting holes 112, meaning that the mounting bosses 111 and the first connecting holes 112 are arranged in a one-to-one correspondence, and the distance between the seven mounting bosses 111 and the first connecting holes 112 and the center of the cylinder block is equal. Generally, it is preferable that the seven mounting bosses 111 and the seven first connecting holes 112 are evenly arranged.

[0041] Of course, in other embodiments of this utility model, the number of mounting bosses 111 and first connecting holes 112 can be one, three, five, eight, etc., and the number of first connecting holes 112 on a single claw can be two, three, four, etc. The specific number and correspondence of mounting bosses 111 and first connecting holes 112 are not limited.

[0042] It is worth noting that in this embodiment, the multiple mounting bosses 111 are arranged in a ring (which can be understood as the connecting line of the multiple mounting bosses 111 being arc-shaped). In other embodiments, the multiple mounting bosses 111 can be arranged in other semi-enclosed shapes (which can be understood as the connecting line of the multiple mounting bosses 111 having some straight lines, such as U-shaped). The specific arrangement of the multiple mounting bosses 111 is not limited.

[0043] Similarly, the number of second connecting holes 121 can be multiple, with multiple second connecting holes 121 spaced apart along the circumferential direction of the motor stator 120.

[0044] Specifically, there are nine second connecting holes 121. The distance between the nine second connecting holes 121 and the center of the motor stator 120 is equal. Seven of the second connecting holes 121 correspond to the seven first connecting holes 112, and the other two second connecting holes 121 are used to correspond to the connecting holes on the oil pan.

[0045] Please refer to Figure 1 and Figure 2In order to improve the positioning accuracy and convenience of the motor stator 120 and the cylinder block 110, the integrated cylinder block 100 may also include a positioning pin 140, the mounting boss 111 is provided with a first positioning hole 113, the motor stator 120 is provided with a second positioning hole 122, and the positioning pin 140 cooperates with both the first positioning hole 113 and the second positioning hole 122.

[0046] Specifically, there are two sets of the first positioning hole 113, the second positioning hole 122, and the positioning pin 140. The two sets of positioning pins 140 can be round pins and diamond pins, respectively. Of course, the number of the first positioning hole 113, the second positioning hole 122, and the positioning pin 140 can also be one, three, or four sets, etc., to achieve the effect of under-positioning or over-positioning. The specific number of sets of the first positioning hole 113, the second positioning hole 122, and the positioning pin 140 is not limited.

[0047] Preferably, the cross-sections of the first positioning hole 113 and the second positioning hole 122 are both circular; of course, the cross-sections of the first positioning hole 113 and the second positioning hole 122 can also be rectangular, fan-shaped, triangular or other shapes. The cross-sectional shape of the positioning pin 140 can be adjusted adaptively. The cross-sectional shapes of the first positioning hole 113 and the second positioning hole 122 can be the same or different. The specific cross-sectional shapes of the first positioning hole 113, the second positioning hole 122 and the positioning pin 140 are not limited.

[0048] Please refer to Figure 1 and Figure 2 In order to improve the structural strength of the cylinder block 110, a first reinforcing rib 114 can be formed at one end of the cylinder block 110. The first reinforcing rib 114 is connected to the mounting boss 111 and extends radially along the cylinder block 110, thereby enabling the mounting boss 111 on the cylinder block 110 that is connected, positioned and supported by the motor stator 120 to have sufficient structural strength.

[0049] It should be noted that, in order to avoid the first reinforcing rib 114 interfering with the motor stator 120, the mounting boss 111 can be made to protrude from the first reinforcing rib 114. That is, while the mounting boss 111 is in contact with the motor stator 120, there is a safe distance between the first reinforcing rib 114 and the motor stator 120.

[0050] Similarly, in order to further improve the structural strength of the cylinder block 110, a second reinforcing rib 115 is formed at one end of the cylinder block 110. The second reinforcing rib 115 is connected to the mounting boss 111 and extends along the circumference of the cylinder block 110. The mounting boss 111 protrudes from the second reinforcing rib 115.

[0051] It should be noted that, in order to avoid the second reinforcing rib 115 interfering with the motor stator 120, the mounting boss 111 can protrude from the second reinforcing rib 115. That is, while the mounting boss 111 is in contact with the motor stator 120, there is a safe distance between the second reinforcing rib 115 and the motor stator 120.

[0052] Please refer to Figure 1 and Figure 2 In order to better accommodate and install the motor stator 120, a mounting groove 116 can be formed at one end of the cylinder block seat 110, the motor stator 120 is accommodated in the mounting groove 116, and the mounting boss 111 is located at the bottom of the mounting groove 116.

[0053] This can be understood as follows: after the motor stator 120 contacts and connects with the mounting boss 111 to complete the assembly, part or all of the motor stator 120 is contained in the mounting groove 116, thereby providing better protection for the motor stator 120.

[0054] Secondly, embodiments of this utility model also provide a range extender for use in automobiles. The range extender includes the aforementioned integrated cylinder block 100, as well as an engine component and a generator component. Both the engine component and the generator component can be connected to the cylinder block seat 110, and the generator component can also cooperate with the motor stator 120. This range extender, including the integrated cylinder block 100, possesses all the functions of the integrated cylinder block 100.

[0055] Thirdly, embodiments of this utility model also provide an automobile, which includes the aforementioned range extender, as well as a power battery system, a power drive system, a vehicle control system, and a vehicle body. Each system and the range extender are installed in different locations on the vehicle body and work together to achieve the driving force for the vehicle's movement. Specifically, the automobile can be a sedan, SUV, van, or truck, etc., and the specific type of automobile is not limited. The automobile includes a range extender and possesses all the functions of a range extender.

[0056] In summary, the integrated cylinder block, range extender, and automobile provided by the embodiments of this utility model have at least the following advantages:

[0057] (1) The motor stator 120 can be contacted by mounting boss 111, and the motor stator 120 and cylinder block seat 110 can be connected by fastener 130, which simplifies the installation steps of motor stator 120, improves assembly efficiency and reduces assembly cost.

[0058] (2) The positioning pin 140 can simultaneously cooperate with the first positioning hole 113 and the second positioning hole 122, which improves the positioning accuracy and convenience of the motor stator 120 and the cylinder block seat 110.

[0059] (3) By setting a first reinforcing rib 114 and a second reinforcing rib 115 connected to the mounting boss 111, the structural strength of the cylinder block seat 110 can be improved, and the mounting boss 111 protrudes from the first reinforcing rib 114 and the second reinforcing rib 115, thereby avoiding interference between the first reinforcing rib 114, the second reinforcing rib 115 and the motor stator 120.

[0060] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
