Description

Technical Field

[0001] The utility model belongs to the technical field of charging control, and in particular relates to a charger and a power switching device thereof. Background Art

[0002] At present, the power switching of the charger of the aerial work vehicle is basically realized by a twisting key switch or a selection switch, that is, the charger outputs the corresponding charging voltage to charge the aerial work vehicle by twisting or selecting a gear, and the arrow indicates the corresponding power level. This implementation method makes the hardware design more complicated. At night or when the logo is worn, the power level indicated by the arrow is not easy for the operator to identify; and each default power gear selection must be manually switched to the default position. If the gear is not manually adjusted according to the on-site usage, it is easy to have the actual power supply line only meet 10A charging, but the 16A charging gear is selected, which may cause the line to burn out and other problems, and there are unsafe factors. Utility Model Content

[0003] The utility model aims to provide a charger and a power switching device thereof to solve the problem that the operator has difficulty in identifying the gear position or the identification is not conspicuous, and the problem that the charging gear position is likely to be higher than the required gear position due to the need to manually switch to the default position, thereby causing the circuit to burn out.

[0004] The utility model solves the above technical problems through the following technical solutions: a power switching device of a charger comprises a charging control module, a gear button and an indicator light; the gear button and the indicator light are connected to the charging control module, and the charging control module is connected to a battery; when the charging control module is connected to an external power source through a plug, the charging control module enables the lowest power gear to start charging.

[0005] Furthermore, the output current of the lowest power gear is 10A.

[0006] Furthermore, the gear button is a spring-loaded button.

[0007] Based on the same concept, the utility model provides a power switching device for a charger, including a charging control module and a color-controllable lighted button; the lighted button is connected to the charging control module, and the charging control module is connected to a rechargeable battery; when the charging control module is connected to an external power source through a plug, the charging control module enables the lowest power gear to start charging.

[0008] Based on the same concept, the utility model provides a charger including the power switching device as described above.

[0009] Beneficial Effects

[0010] Compared with the prior art, the advantages of the utility model are:

[0011] Each time the power switching device provided by the utility model is powered on (i.e. the plug is inserted into the AC power socket), the charging control module enables charging at the lowest power gear, ensuring that the device works at the safest gear each time it is powered on, avoiding the charging power gear being higher than the actually required power gear, thereby avoiding the problem of line burning and reducing safety risks; at different power gears, the indicator lights display different colors, clearly showing the switching of the charging power gear, facilitating operation, and solving the problem of difficulty or inconspicuousness in the gear identification for the operator. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] In order to more clearly illustrate the technical solution of the present invention, the drawings required for use in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are only one embodiment of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0013] Figure 1 It is a structural schematic diagram of the power switching device of the charger in the embodiment of the utility model. DETAILED DESCRIPTION

[0014] The following is a clear and complete description of the technical solution in the utility model in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] The technical solution of the present application is described in detail with specific embodiments below. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0016] Example 1

[0017] like Figure 1 As shown, a power switching device of a charger provided by an embodiment of the utility model includes a charging control module, a gear button S and an indicator light LED; the gear button S and the indicator light LED are connected to the charging control module, and the charging control module is connected to the rechargeable battery of the aerial work vehicle; when the charging control module is connected to an external power supply through a plug, the charging control module enables the lowest power gear to start charging.

[0018] The specific working process of the power switching device of the utility model is as follows: when the plug is inserted into the mains socket (i.e., the external power supply), the charging control module enables the lowest power gear to charge the rechargeable battery of the aerial work vehicle, which means that the default lowest power gear is enabled to start charging, and the indicator LED displays green, indicating that the device is working in the lowest power gear (i.e., the first power gear); when it is necessary to switch to a power gear one level higher than the lowest power gear (i.e., the second power gear), long press the gear button S and hold it for 3 seconds (the time is adjustable), then it can be switched to the second power gear, and the indicator LED displays yellow; when it is necessary to switch to a power gear one level higher than the second power gear (i.e., the third power gear), long press the gear button S and hold it for 3 seconds (the time is adjustable), then it can be switched to the third power gear, and the indicator LED displays blue; and so on, at the highest level of power gear, long press the gear button S and hold it for 3 seconds, then it can be switched to the lowest power gear. Therefore, the charging power gear can be switched by long pressing the gear button S. Only one gear button S and one indicator LED are used, reducing the hardware circuit design.

[0019] Each time the power is turned on (i.e. the plug is inserted into the AC power socket), the charging control module enables charging at the lowest power gear, ensuring that the device works at the safest gear each time it is powered on. Even if the operator or site is changed, charging can be started at the lowest power gear, avoiding the charging power gear being higher than the actually required power gear, thereby avoiding the problem of line burning, reducing safety risks, and ensuring the safety of the charging line; at different power gears, the indicator LED displays different colors, clearly showing the switching of the charging power gear, facilitating operation, and solving the problem of operators having difficulty or inconspicuous identification of the gear.

[0020] In the embodiment of the utility model, the output current of the lowest power gear is 10A, the output current of the second power gear is 16A, and the output current of the third power gear is 32A. That is, each time charging is restarted, the charging control module uses the lowest power gear of 10A for charging, avoiding the problem of the actual power line only needing 10A for charging in the traditional technology, but the charger outputs 16A, thus causing the line to burn; the power gear can be switched by long pressing the gear button.

[0021] In the embodiment of the utility model, the shift button S is a spring-type button. After the shift button S is released, the shift button S automatically resets.

[0022] The computer program involved in the utility model for realizing gear switching by long pressing a button is prior art, and reference can be made to the Chinese patent document with publication number CN115778806A and titled Single-button Control Method Based on Massager.

[0023] Example 2

[0024] A power switching device of a charger provided by an embodiment of the utility model includes a charging control module and a color-controllable lighted button; the lighted button is connected to the charging control module, and the charging control module is connected to a rechargeable battery of an aerial work vehicle; when the charging control module is connected to an external power source through a plug, the charging control module enables the lowest power gear to start charging.

[0025] The specific working process of the power switching device of the utility model is as follows: when the plug is inserted into the mains socket (i.e., the external power supply), the charging control module enables the lowest power gear to charge the rechargeable battery of the aerial work vehicle, which means that the default lowest power gear is enabled to start charging, and the light of the lighted button displays green, indicating that the device is working in the lowest power gear (i.e., the first power gear); when it is necessary to switch to a power gear one level higher than the lowest power gear (i.e., the second power gear), long press the lighted button and hold it for 3 seconds (the time is adjustable), then it can be switched to the second power gear, and the light of the lighted button displays yellow; when it is necessary to switch to a power gear one level higher than the second power gear (i.e., the third power gear), long press the lighted button and hold it for 3 seconds (the time is adjustable), then it can be switched to the third power gear, and the light of the lighted button displays blue; and so on, at the highest level of power gear, long press the lighted button and hold it for 3 seconds, then it can be switched to the lowest power gear. Therefore, the charging power level can be switched by long pressing the button with light, and only one button with light is used, reducing the hardware circuit design.

[0026] In the embodiment of the utility model, the output current of the lowest power gear is 10A, the output current of the second power gear is 16A, and the output current of the third power gear is 32A. That is, each time charging is restarted, the charging control module uses the lowest power gear of 10A for charging, avoiding the problem of the actual power line only needing 10A for charging in the traditional technology, but the charger outputs 16A, thus causing the line to burn; the power gear can be switched by long pressing the button with light.

[0027] In the embodiment of the utility model, the button with light is a spring-type button, and after the button with light is released, the button with light is automatically reset.
