Description

Technical Field

[0001] The present application relates to the field of portable means of transportation, and in particular to an electric scooter. Background Art

[0002] With the accelerating pace of life, more people are choosing electric scooters as a means of transportation for going out and commuting. Existing electric scooters have front and rear wheels mounted on the front and rear ends of the underbody, respectively. The body has pedals for the user to stand on, and a drive unit is located at the top of the front end of the body. The drive unit controls the front and / or rear wheels of the electric scooter to start and stop the scooter. The main power source of the drive unit is generally a lithium battery pack. Electric scooters also include a controller, which is primarily used to drive the motor, but also for powering other components and performing corresponding controls. Specifically, the controller integrates control circuits such as voltage detection circuits and step-down circuits.

[0003] In existing technology, the controller output and meter input must match. For example, when using a 12V meter, a controller with a 12V output is required, and when using a P+ meter, a controller with a P+ output is required. P+ refers to the output voltage of the lithium battery pack, which can generally be 30V-45V. A drawback: Due to the matching of the input and output voltages of the controller and meter, the same controller cannot be compatible with meters of different voltages. Utility Model Content

The accompanying drawings are not necessarily drawn to scale, and local features may be enlarged or reduced to more clearly illustrate the details of the local features.

[0044] In order to fully understand the present application, detailed steps and detailed structures will be presented in the following description to illustrate the technical solution of the present application. The preferred embodiments of the present application are described in detail below. However, in addition to these detailed descriptions, the present application may also have other implementation methods.

[0045] In view of the technical problems in the related art, the embodiment of the present application provides an electric scooter. Figure 1 , the electric scooter comprises:

[0046] A power supply 10 configured to output a power supply voltage of a first preset value;

[0047] The first meter 21 has an operating voltage of a first voltage of a first preset value;

[0048] A second meter 22, having an operating voltage of a second voltage of a second preset value, wherein the second preset value is smaller than the first preset value;

[0049] The power distributor 30 has an input end electrically connected to the power supply 10; the output end of the power distributor 30 is provided with a first interface 31 and a second interface 32 capable of outputting a first voltage and a second voltage, and the interface specifications of the first interface 31 and the second interface 32 are different;

[0050] The wiring harness assembly has one end connected to at least one of the first interface or the second interface, and the other end connected to at least one of the first meter or the second meter. It is understood that the power supply 10 may be a battery assembly. In the electric scooter of this embodiment, the first preset value may be 30V-45V. The first meter 21 may be referred to as a P+ meter, and the second meter 22 may be referred to as a 12V meter. It is understood that meters with other operating voltages may also be used.

[0051] It can be understood that, in an actual electric scooter, the power distributor 30 can be integrated into the controller of the electric scooter.

[0052] Furthermore, the present technical solution may also include a third instrument and more instruments, and the power distributor 30 may include a third interface and more interfaces, which will not be described in detail.

[0053] The electric scooter of an embodiment of the present application is provided with a first interface 31 and a second interface 32 that output different voltage values ​​on the power distributor 30, and a wiring harness assembly is provided. One end of the wiring harness assembly is connected to at least one of the first interface or the second interface, and the other end is connected to at least one of the first meter 21 or the second meter 22, so that the same power distributor 30 can adapt to meters with two working voltages.

[0054] In some other embodiments of the present application, the wiring harness assembly includes:

[0055] a first wiring harness assembly, one end of which is electrically connected to the first meter and the other end of which includes a first terminal capable of being plugged into the first interface;

[0056] The second wiring harness assembly has one end electrically connected to the second meter and the other end including a second terminal capable of being plugged into the second interface.

[0057] The wiring harness assembly is divided into two, which is more reliable and less prone to wiring errors.

[0058] Furthermore, the first wiring harness assembly 41 includes a first terminal 411, and the second wiring harness assembly 42 includes a second terminal 421, corresponding to the first and second interfaces 31 and 32, which have different interface specifications. This prevents the first meter 21 from being electrically connected to the second interface 32 and causing insufficient voltage to cause it to malfunction, or the second meter 22 from being electrically connected to the first interface 31 and causing damage due to excessive voltage. This is a design feature that provides a foolproof structure.

[0059] In some other embodiments of the present application, the first wiring harness assembly 41 includes:

[0060] A first wiring harness 412 , one end of which is electrically connected to the power distributor 30 ;

[0061] a second wiring harness 413, one end of which is electrically connected to the first meter 21; the other ends of the first wiring harness 412 and the second wiring harness 413 are electrically connected to each other through a first connection method, so as to realize the electrical connection between the power distributor 30 and the first meter 21;

[0062] The second wiring harness assembly 42 includes:

[0063] A third wiring harness 422 , one end of which is electrically connected to the power distributor 30 ;

[0064] One end of the fourth wiring harness 423 is electrically connected to the second meter 22 ; the other ends of the third wiring harness 422 and the fourth wiring harness 423 are electrically connected to each other through a second connection method to achieve electrical connection between the power distributor 30 and the second meter 22 .

[0065] To facilitate maintenance during production and use, the first wiring harness assembly 41 includes a first wiring harness 412 and a second wiring harness 413. During production, the first wiring harness 412 and the power distributor 30 can be electrically connected first, and the second wiring harness 413 and the first meter 21 can be electrically connected. Finally, the first wiring harness 412 and the second wiring harness 413 can be electrically connected to achieve electrical connection between the power distributor 30 and the first meter 21.

[0066] Similarly, the second wire harness assembly 42 includes a third wire harness 422 and a fourth wire harness 423 .

[0067] This creates the possibility of incorrect connections between the wiring harnesses, for example, connecting the first wiring harness 412 to the fourth wiring harness 423, or connecting the second wiring harness 413 to the third wiring harness 422. This connection error has the same consequences as if the wiring harness assembly were incorrectly connected to the interface of the power distributor 30. Therefore, the connection modes between the wiring harnesses in the two wiring harness assemblies are set to different modes, namely the first connection mode and the second connection mode, to avoid connection errors.

[0068] In some other embodiments of the present application, the first wiring harness 412 and the fourth wiring harness 423 are both provided with a first connector 414 for electrical connection, and the second wiring harness 413 and the third wiring harness 422 are provided with a second connector 415 that cooperates with the first connector 414 .

[0069] It is understandable that the first connector 414 and the second connector 415 can be standard connection terminals and are mutually compatible and one-to-one corresponding, thus reducing the cost.

[0070] It can be understood that although there are only two types of connectors, since connectors of the same type cannot be connected, incorrect connection is avoided.

[0071] In some other embodiments of the present application, the first connector 414 is a male connector, and the second connector 415 is a female connector that mates with the male connector.

[0072] The male and female structure forms a mating connection, which is simpler in structure and is also the main structure of many standard connection terminals. It has low cost and high reliability.

[0073] In some other embodiments of the present application, the first interface 31 is a 3-position interface, and the first terminal 411 is a 3-position connector.

[0074] Understandably, the 3-digit designation can be DIN 3P. DIN stands for Deutsche Industrienormen, the German Industrial Standard, and P stands for "Pin," meaning the number of pins on a connector. This design provides an electrical connection structure adapted to the input method of the first meter 21.

[0075] In some other embodiments of the present application, the second interface 32 is a 5-position interface, and the second terminal 421 is a 5-position connector.

[0076] Similarly, the 5th position can be DIN 5P, which is an electrical connection structure adapted to the input mode of the second meter 22 .

[0077] In other embodiments of the present application, refer to Figure 2 The other end of the first wiring harness assembly 41 also includes a third terminal 416, and either the third terminal 416 or the first terminal 411 is used; the third terminal 416 is a 5-position connector that can be plugged into the second interface 32.

[0078] Thus, in some cases, the first wiring harness assembly 41 can electrically connect the power distributor 30 to the first meter 21, and also to the second meter 22, providing a single wire for multiple uses. It is understood that the second wiring harness assembly 42 can also have a similar configuration. It is also understood that the wiring harness assembly can have more connecting terminals.

[0079] In some other embodiments of the present application, the power distributor 30 includes:

[0080] a detection circuit configured to detect the power supply voltage; an input end of the detection circuit is electrically connected to the power supply 10, and an output end of the detection circuit is electrically connected to the first meter 21;

[0081] The first step-down circuit is configured to step down the power supply voltage and output it; the input end of the step-down circuit is electrically connected to the power supply 10 , and the output end is electrically connected to the second meter 22 .

[0082] That is, the output end of the detection circuit can output a first voltage, and the output end of the first step-down circuit can output a second voltage. The detection circuit is not shown in the figure, but is located in the power distributor 30.

[0083] It is understandable that the power distributor 30 is also provided with a voltage detection function to ensure the operation of the instrument. It should be noted that the first step-down circuit is mainly used to reduce the voltage, but it also performs corresponding detection on the final output voltage to ensure the operation of the instrument.

[0084] Specifically, the step-down circuit may be a DC-to-DC converter (DCDC) step-down circuit. Similarly, the first step-down circuit is not shown in the figure and is located in the power distributor 30 .

[0085] In other embodiments of the present application, refer to Figure 3 The electric scooter further includes a taillight 50, and the power input end of the taillight 50 is electrically connected to the output end of the first step-down circuit.

[0086] That is, the operating voltage of the taillight 50 is the same as that of the second meter 22 , and therefore, the power input end of the taillight 50 can be electrically connected to the output end of the first step-down circuit.

[0087] Specifically, an electrical connection line arranged in parallel with the second wiring harness assembly 42 may be provided.

[0088] In this embodiment, the operating voltage of the second meter 22 is 12V. Figure 3 It is marked as 12V. The power supply voltage is marked as P+.

[0089] In other embodiments of the present application, refer to Figure 3 The electric scooter further includes a turning handle 61, a brake handle 62 and a headlight 63; the second instrument 22 includes:

[0090] The second step-down circuit has an input end electrically connected to the output end of the first step-down circuit, and an output end electrically connected to the throttle 61 , the brake handle 62 and the headlight 63 .

[0091] It should be noted that the operating voltage of the throttle 61, brake lever 62, and headlight 63 in this embodiment is less than a second preset value, for example, 5V / 6V. In the prior art, this is achieved by directly stepping down the power supply voltage to 5V / 6V, but this step-down structure is relatively costly. This embodiment reduces costs by providing two step-down circuits. Similarly, the second step-down circuit, not shown in the figure, is located in the second instrument 22.

[0092] It should be understood that the above embodiments are exemplary and are not intended to encompass all possible implementations of the technical solutions of the present application. Various modifications and variations may be made based on the above embodiments without departing from the scope disclosed herein. Similarly, the various technical features of the above embodiments may be arbitrarily combined to form additional embodiments of the present application that may not be explicitly described. Therefore, the above embodiments merely illustrate several implementations of the present application and do not limit the scope of protection of the patent application.
