Description

Technical Field

[0001] The utility model relates to the technical field of golf cart steering modes, in particular to a steering structure with an electronic power steering machine. Background Art

[0002] An electric golf cart is an electric vehicle designed specifically for use on golf courses, usually used to carry golfers and golf clubs across the course. This vehicle is usually equipped with an electric motor and is powered by batteries, which can provide sufficient power and range for efficient transportation on the course.

[0003] When driving an electric golf cart, it is necessary to control the cart to steer. However, the power steering method used in traditional electric golf carts is to add an electronic power steering on the steering column, which occupies a large space on the steering column, resulting in the vertical compression of the space of the cart to a certain extent. Utility Model Content

[0004] The utility model aims to provide a steering structure with an electronic power steering mechanism to solve the problem that an electronic power steering mechanism is added to the steering column in the above background, which occupies a large space on the steering column.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A steering structure with an electronic power steering gear comprises a steering gear, an electronic power steering system is arranged on the outer surface of the steering gear, the steering gear is connected to a controller via a connecting line; and steering rods are arranged on both sides of the steering gear.

[0007] As a further solution of the utility model: one end of the steering rod is connected to the wheel through a clevis.

[0008] As a further solution of the utility model: the two groups of wheels are symmetrically arranged, and the outer surfaces of the two groups of wheels are provided with anti-skid grooves.

[0009] As a further solution of the utility model: the outer surface of the steering rod is covered with a protective sleeve, and the two ends of the protective sleeve are connected and fixed to the outer surface of the steering rod through a fixing piece.

[0010] As a further solution of the utility model: the fixing piece is configured as a metal clamp.

[0011] As a further solution of the utility model: a universal joint is arranged on one side of the steering machine, a steering column is connected to the upper side of the universal joint, and a steering wheel is arranged on one end of the steering column.

[0012] Beneficial effects of the utility model:

[0013] (1) The utility model adds electronic power assistance to the steering gear and controls it through a controller. This power assistance method does not occupy the space of the steering column, so that the space occupied by this part of the steering column is small;

[0014] (2) The utility model integrates the entire power-assist mechanism into the steering gear. In general, steering failures often occur in the steering gear and the power-assist steering system. Therefore, during general maintenance, steering failures basically only occur in the power-assist steering system. In addition, the steering gear of the electric golf cart is installed at the front of the vehicle, which is easier to disassemble and repair. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions 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.

[0020] Embodiment 1

[0021] See also Figure 1-2 As shown, the utility model is a steering structure with an electronic power steering machine, comprising a steering machine 2, and an electronic power steering system is arranged on the outer surface of the steering machine 2;

[0022] Since the power steering method used in the conventional electric golf cart is to add an electronic power steering system to the steering column 7, this power steering method will take up a large space for the steering column 7 and more space at the lower end of the steering wheel 8;

[0023] Therefore, an electronic power steering system is added to the steering gear 2, so that the steering column 7 is not too bulky, saving installation space and increasing the space in the vertical direction;

[0024] It should be noted that, in general, the steering failure of the vehicle often occurs in the steering gear 2 and the power steering system. Therefore, during the maintenance process, the steering failure basically only occurs in the power steering system. In addition, the steering gear 2 of the electric golf cart is located at the front of the vehicle, that is, the electronic power steering system is installed on the steering gear 2, which is easier to disassemble and repair, reducing the workload of maintenance.

[0025] The electronic power steering system is a torque converter, a steering shaft and a pinion gear connected together. When the steering shaft rotates, the torque sensor converts the relative angular displacement between the input shaft and the output shaft under the action of the torsion bar into an electrical signal and transmits it to the ECU. The ECU determines the rotation direction and power size of the motor according to the vehicle speed sensor and torque sensor signals, thereby completing real-time control of the power steering.

[0026] The steering machine 2 is connected to the controller 3 via a connecting line;

[0027] Steering tie rods 1 are provided on both sides of the steering machine 2;

[0028] Wherein, the outer surface of the steering rod 1 is covered with a protective sleeve;

[0029] The protective sleeve is made of a deformable rubber material, and can be extended and folded along with the movement of the steering rod 1;

[0030] Furthermore, the outer surface of the protective sleeve is provided with a protective layer, and the protective layer includes a corrosion-resistant layer, a wear-resistant layer and a high-temperature-resistant layer;

[0031] More specifically, the corrosion-resistant layer is an anti-corrosion coating applied on the outer surface of the protective cover, thereby protecting the protective cover from being corroded and damaged by rainwater after rain;

[0032] The two ends of the protective sleeve are connected and fixed to the outer surface of the steering rod 1 through fixing pieces;

[0033] The protective sleeve is connected to the steering tie rod 1 through a fixing piece, and the protective sleeve and the steering tie rod 1 are sealed to reduce the external dust from entering the interior of the protective sleeve and affecting the connection structure inside the protective sleeve, thereby affecting the steering effect;

[0034] Wherein, the fixing piece is configured as a metal clamp;

[0035] The metal clamp is used for fixing, which is adapted to the shape of the steering tie rod 1. It is easy to keep the protective sleeve and the steering tie rod 1 in a coaxial position during installation, and it is more convenient during installation;

[0036] One end of the steering tie rod 1 is connected to a wheel 4 via a clevis 5;

[0037] The two sets of wheels 4 are symmetrically arranged, and the outer surfaces of the two sets of wheels 4 are provided with anti-skid patterns;

[0038] The anti-skid pattern has an anti-skid effect when the wheel 4 turns, increases the friction between the ground and the surface of the wheel 4, improves the stability of the vehicle during driving, and reduces the possibility of rollover due to centrifugal force during turning;

[0039] A universal joint 6 is provided on one side of the steering machine 2, a steering column 7 is connected to the upper side of the universal joint 6, and a steering wheel 8 is provided at one end of the steering column 7;

[0040] Embodiment 2

[0041] This embodiment provides a vehicle, the vehicle comprising an electric golf cart;

[0042] The electric golf cart includes the steering machine 2 with the electronic power steering system in the first embodiment.

[0043] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
