Description

Technical Field

[0001] The utility model belongs to the technical field of power supply control, and more specifically, relates to a power supply control structure. Background Art

[0002] Construction vehicles are the backbone of a construction project, significantly reducing manpower and accelerating the progress of construction projects. However, they operate in harsh environments, making it easy for foreign matter to enter the vehicle, which can negatively impact the performance of its components.

[0003] The power control structure is an important component for engineering vehicle control. It relies on the combination of contact components and electrode sheets to achieve on-off control of the engineering vehicle's power supply. To facilitate operation and heat dissipation, the existing power control structure will set a corresponding gap on the shell. External impurities will enter the interior of the power control structure through this gap. If external impurities fall on the electrode sheet, when the contact plate in the contact component contacts the electrode sheet, poor contact will occur, resulting in a decrease in the sensitivity of the power control structure, affecting its normal use and even the driving safety of the engineering vehicle. Therefore, it is necessary to improve the existing power control structure to ensure the normal use of the power control structure and the driving safety of the engineering vehicle.

[0006] The power control structure includes a housing, a contact assembly, and a first electrode sheet and a second electrode sheet disposed opposite to the lower end of the contact assembly;

[0007] The contact assembly includes a joystick inserted into the housing, and a rotary disk, a spring, and a touch plate sequentially sleeved on the joystick from top to bottom. The rotary disk is symmetrically provided with a first brush and a second brush for cleaning the first electrode sheet and the second electrode sheet, respectively.

[0008] The lower ends of the first electrode sheet and the second electrode sheet are connected to a first terminal and a second terminal respectively. The first terminal and the second terminal are both used to be connected to the control end.

[0014] Optionally, the sizes of the first contact sheet and the second contact sheet are both smaller than the sizes of the first electrode sheet and the second electrode sheet.

[0015] The beneficial effects of the present invention are:

Based on one or more embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of the present invention.

[0042] Reference Figure 1-3 , an embodiment of the present utility model provides a power supply control structure, which is configured to be electrically connected to a control terminal of a power supply system of an engineering vehicle;

[0043] The power control structure includes a housing 1, a contact assembly, and a first electrode sheet 2 and a second electrode sheet 3 arranged opposite to the lower end of the contact assembly;

[0044] The contact assembly includes a joystick 4 inserted into the housing 1, and a rotary disk 5, a spring 6, and a touch plate 7 sequentially sleeved on the joystick 4 from top to bottom. The rotary disk 5 is symmetrically provided with a first brush and a second brush for cleaning the first electrode sheet 2 and the second electrode sheet 3, respectively. The touch plate 7 can be connected to the first electrode sheet and the second electrode sheet through the joystick 4.

[0045] The lower ends of the first electrode sheet 2 and the second electrode sheet 3 are connected to a first terminal 8 and a second terminal 9 respectively. The first terminal 8 and the second terminal 9 are both used to be connected to the control end.

[0046] In one embodiment, a portion of the operating lever 4 that extends beyond the housing 1 is covered with a turning handle 10 for operating the operating lever 4 .

[0047] In one embodiment, a first contact piece 71 and a second contact piece 72 for connecting to the first electrode piece 2 and the second electrode piece 3 are symmetrically provided at the lower end of the touch panel 7 .

[0048] Specifically, when the handle is manually turned, the control lever can drive the touch plate to rotate, so that the first contact piece and the second contact piece are respectively connected to the first electrode piece and the second electrode piece, thereby electrically connecting the first terminal and the second terminal to realize the regulation of the control end of the power supply system of the engineering vehicle.

[0049] In a specific embodiment, the first contact piece 71 and the second contact piece 72 are both smaller than the first electrode piece 2 and the second electrode piece 3. This allows the first contact piece and the second contact piece to fully contact the first electrode piece and the second electrode piece, respectively, thereby improving the sensitivity of the power control structure and ensuring the stability of the power supply system.

[0050] In one embodiment, a baffle 11 for limiting the position of the turntable 5 is sleeved on the upper end of the control lever 4 .

[0051] In one embodiment, the upper surface of the turntable 5 is provided with a plurality of protrusions 51 for connecting with the baffle 11 .

[0052] Specifically, when the turntable moves downward under the drive of the joystick, friction is generated between the several protrusions and the baffle, which helps humans more accurately judge the rotation trajectory of the joystick and ensure that the power control structure is in the on or off state.

[0053] In one embodiment, the first brush and the second brush each include a connecting rod 12 and a brush head 13, and the brush head 13 is connected to the suction cup 5 via the connecting rod 12. Specifically, the brush head can be made of nylon, sponge, etc., but the present invention is not limited thereto. Any brush material that can achieve the same technical effect as the present invention is also within the scope of protection of the present invention.

[0054] When in use, the power control structure of the present invention can be installed in the engineering vehicle in advance, and the first terminal and the second terminal are connected to the control end of the power supply system. When the power supply system needs to be controlled, the handle can be manually rotated, and the control rod drives the touch plate to rotate, so that the first contact piece and the second contact piece are respectively in contact with or separated from the first electrode piece and the second electrode piece, thereby realizing the connection or disconnection of the power supply. At the same time, the first brush and the second brush also rotate under the drive of the control rod to clean external impurities that fall on the first electrode piece and the second electrode piece.

[0055] The power control structure proposed in the utility model symmetrically arranges the first brush and the second brush on the turntable, so that when the control lever drives the touch plate to rotate, it can simultaneously drive the first brush and the second brush to rotate, so that the first brush and the second brush can clean the upper surfaces of the first electrode sheet and the second electrode sheet to remove external impurities.

[0056] Therefore, compared with the existing power supply control structure, the power supply control structure of the utility model can ensure the cleanliness of the surface of the first electrode sheet and the second electrode sheet, effectively prevent the power supply control structure from having poor contact and the like, thereby ensuring the normal use of the power supply control structure and the driving safety of the engineering vehicle.

[0057] Although one or more embodiments of the present invention have been described above, it should be understood by those skilled in the art that the present invention can be implemented in any other form without departing from its spirit and scope. Therefore, the embodiments described above are illustrative and not restrictive, and many modifications and substitutions will be apparent to those skilled in the art without departing from the spirit and scope of the present invention as defined in the appended claims.
