[0034] As mentioned in the background section, a range extender generally refers to an electric vehicle component that provides additional electrical energy, thereby increasing the driving range of an electric vehicle. It is usually understood as a combination of an engine and a generator. To further improve the vehicle's range, range extenders are typically optimized in design to make them smaller and lighter. However, during the optimization process, existing wiring terminals are mostly copper busbar structures, which cannot meet the optimized wiring requirements.

[0035] Please refer to Figure 1 and Figure 2 The terminal block 100, range extender, and vehicle provided in the embodiments of this utility model can solve the above problems, and will be described in detail below.

[0036] In a first aspect, embodiments of the present invention provide a terminal block 100, which includes a base 110, a first wiring portion 120, and a second wiring portion 130;

[0037] The first wiring portion 120 and the second wiring portion 130 are respectively connected to the two sides of the base 110. The first wiring portion 120 has a flexible section 122. The first wiring portion 120 is used to connect to the motor stator, and the second wiring portion 130 is used to connect to the controller.

[0038] During the wiring process, the wiring operation with the controller can be achieved through the second wiring part 130, and the wiring operation with the motor stator can be achieved through the first wiring part 120. Furthermore, the flexible section 122 in the first wiring part 120 can improve the wiring flexibility, thereby meeting the wiring requirements under special shape and position conditions.

[0039] In this embodiment, there are three first wiring portions 120, which are arranged in a straight line and are equidistant from each other. Of course, in other embodiments of this utility model, the number of first wiring portions 120 can also be one, two, four, seven, etc., and the specific number of first wiring portions 120 is not limited. Furthermore, if the arrangement conditions permit, multiple first wiring portions 120 can also be arranged in multiple rows or columns or in an arc shape, and the specific arrangement and arrangement of the first wiring portions 120 is not limited.

[0040] In this embodiment, there are three second wiring portions 130, which are arranged in a straight line and are equidistant from each other. Of course, in other embodiments of this utility model, the number of second wiring portions 130 can be one, two, four, etc., and the specific number of second wiring portions 130 is not limited. Furthermore, if the arrangement conditions permit, multiple second wiring portions 130 can also be arranged in multiple rows or columns or in an arc shape, and the specific arrangement and arrangement of the second wiring portions 130 is not limited.

[0041] Please refer to Figure 1 and Figure 2 The first wiring section 120 also has a fixed section 121 and a connecting section 123. The fixed section 121 and the connecting section 123 are respectively connected to the two ends of the flexible section 122. The fixed section 121 is connected to the base 110, and the connecting section 123 is used to connect the motor stator.

[0042] The fixing part is made of rigid material and is used to connect the flexible section 122 and the base 110. The connecting section 123 is also made of rigid material and has a first connecting hole 1231 to facilitate connection with the motor stator.

[0043] In this embodiment, the number of first connecting holes 1231 on a single connecting segment 123 is one, and the cross-section of the first connecting hole 1231 is circular. Of course, in other embodiments of this utility model, the number of first connecting holes 1231 on a single connecting segment 123 can be two, three, five, etc., and the cross-sectional shape of the first connecting hole 1231 can be fan-shaped, rectangular, triangular, etc. The specific number and cross-sectional shape of the first connecting hole 1231 are not limited.

[0044] It should be noted that, in order to ensure that the first wiring section 120 has sufficient flexible adjustment space, the extension length of the flexible section 122 can be greater than the extension lengths of both the fixed section 121 and the connecting section 123, and the extension length of the flexible section 122 can also be greater than the sum of the extension lengths of the fixed section 121 and the connecting section 123.

[0045] Please refer to Figure 1 and Figure 2 In order to make the overall components work more stably and avoid the negative impact of external impurities or dust on normal operation, a sealing groove 111 can be formed on the end face of the seat 110 near the first wiring part 120. The sealing groove 111 surrounds the second wiring part 130 and is used to accommodate the sealing element.

[0046] Furthermore, in order to reduce the amount of material used in the seal and to ensure that the area enclosed by the sealing groove 111 is not too large, the sealing groove 111 can be made into an arc shape, and the inner sidewall of the sealing groove 111 is set close to the second wiring portion 130.

[0047] In this embodiment, the sealing groove 111 is annular and there is only one. In other embodiments of this utility model, the sealing groove 111 can also be set to two, three, four, etc., thereby forming a multi-layer sealing structure, which greatly improves the overall sealing effect. The specific number of sealing grooves 111 is not limited.

[0048] Please refer to Figure 1 and Figure 2 In order to make a stable connection to the seat 110, the seat 110 can be provided with a second connection hole 112, and the second connection hole 112 is located outside the sealing groove 111.

[0049] In this embodiment, there are four second connecting holes 112, which are respectively disposed at different positions on the outside of the sealing groove 111, and the cross-sectional shape of the second connecting holes 112 is circular. Of course, in other embodiments of this utility model, the number of second connecting holes 112 can be two, three, five, etc., and the cross-sectional shape of the second connecting holes 112 can be fan-shaped, rectangular, triangular, etc. The specific number and cross-sectional shape of the second connecting holes 112 are not limited.

[0050] It is worth noting that two recessed sections are formed on the weight-reducing groove 113. One recessed section is used to avoid the second connecting hole 112, and the other recessed section is used to provide sufficient reserved space at the edge of the seat 110. A straight section is formed on the weight-reducing groove 113, and its extending direction is parallel to the extending direction of the arrangement of the fixing sections 121 of the three first wiring portions 120.

[0051] Please refer to Figure 1 and Figure 2 In order to make the terminal block 100 also lightweight, at least two weight-reducing grooves 113 are formed on the end face of the base body 110 near the second terminal part 130 to reduce weight. A connecting rib 114 is formed between adjacent weight-reducing grooves 113 to maintain strength.

[0052] In this embodiment, some of the weight-reducing grooves 113 are rectangular, and other parts of the weight-reducing grooves 113 have at least one straight side and the other sides can be arc-shaped, so as to maximize the space utilization of the weight-reducing grooves 113. Furthermore, the weight-reducing grooves 113 are arranged in multiple rows and columns. The specific shape and arrangement of the weight-reducing grooves 113 are not limited.

[0053] In addition, in order to avoid the weight reduction groove 113 affecting the structural strength of the seat 110 too much, a sufficient safety distance can be reserved between the weight reduction groove 113 and the edge of the seat 110. The second connecting hole 112 can be opened at the edge of the seat 110 or arranged between multiple weight reduction grooves 113.

[0054] Please refer to Figure 1 and Figure 2 The second wiring section 130 is a copper busbar, and a third connection hole 131 is provided at the end of the second wiring section 130 away from the base 110. Specifically, the second wiring section 130 can be arranged in an L-shape or a U-shape, and there is no limitation on the specific structural shape of the second wiring section 130.

[0055] In this embodiment, the number of third connecting holes 131 on a single second wiring portion 130 is one, and the cross-section of the third connecting hole 131 is circular. Of course, in other embodiments of this utility model, the number of third connecting holes 131 on a single second wiring portion 130 can be two, three, five, etc., and the cross-sectional shape of the third connecting hole 131 can be fan-shaped, rectangular, triangular, etc. The specific number and cross-sectional shape of the first connecting holes 1231 are not limited.

[0056] Furthermore, in order to facilitate the connection of the second wiring section 130 and the controller by fasteners, the wiring dock 100 may also include a locking member 140, which is connected to the second wiring section 130 and is correspondingly provided with the third connection hole 131.

[0057] In this embodiment, the fastener can be a bolt, and the locking member 140 is a nut. The central hole of the nut corresponds to the third connecting hole 131. The shank of the bolt passes through the third connecting hole 131 and connects with the central hole of the nut, thereby improving the connection stability. Of course, in other embodiments of this utility model, the fastener can also be a pin, and the locking member 140 can be a sleeve. The pin passes through the third connecting hole 131 and cooperates with the sleeve, which can also ensure the connection stability to a certain extent.

[0058] Secondly, embodiments of this utility model also provide a range extender, including the aforementioned terminal block 100, and further including a controller, a motor stator, an electronic rotor, engine components, and an integrated cylinder block.
