Description

Technical Field

[0001] This utility model belongs to the field of small vehicle technology and relates to a golf cart with adjustable front seat space. Background Technology

[0002] A golf cart is a small passenger vehicle designed and developed specifically for golf courses. It can also be used as a short-distance transportation tool in resorts, villas, tourist attractions, and other similar locations.

[0003] Because golf carts are typically designed to be compact and simple, their seats are usually fixed directly to the vehicle body, making them unsuitable for people of varying heights. To address this issue, the common practice is to design the seats with an adjustable structure similar to that of passenger cars. For example, Chinese patent application (application number: 202321834825.4) discloses a golf cart with adjustable seating space, including a vehicle chassis with wheels at each of the four corners. A power supply box is located at the top of the chassis, with two rotating discs on top of the power supply box. Each rotating disc has a base on top of its base, with a set of lead screw housings on both sides. A screw rod runs through the center of each lead screw housing, and a knob is located on one side of the screw rod. Two nuts are located in the center of the screw rod, and a support plate is located on one side of each nut. A seat is located on top of the support plate. When adjusting the seat space, rotating the knob moves the nuts on the screw rod along the screw rod axis, causing the seat to move back and forth, thus adjusting the seat space.

[0004] While the above structure allows for adjustment of the seat space, golf carts typically have storage boxes for storing golf clubs behind the seats. If the seats are adjustable, a large amount of space needs to be reserved between the storage boxes and the seats for adjusting the seats. This would result in a larger overall vehicle structure and lower overall utilization of the interior space. Summary of the Invention

[0005] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a golf cart with adjustable front seat space. The technical problem to be solved by this utility model is: how to make the golf cart both adjustable in terms of seat space and more compact in terms of overall vehicle structure.

[0006] The purpose of this utility model can be achieved through the following technical solution: a golf cart with adjustable front seat space, characterized in that it includes a front chassis, a rear chassis, a drive component, and a control system for controlling the drive component, wherein the front chassis is provided with a front wheel, the rear chassis is provided with a rear wheel and a seat, the front chassis and the rear chassis are slidably connected, and the drive component is used to drive the rear chassis to move back and forth relative to the front chassis.

[0007] The chassis of this utility model adopts a split structure with sliding cooperation between the front chassis and the rear chassis. The steering wheel, center console and front wheels are set on the front chassis, while the seats and rear wheels are set on the rear chassis. The space in front of the seats is adjusted by driving the rear chassis to move back and forth relative to the front chassis through the drive component, so as to suit users of different body types.

[0008] Moreover, since this utility model adjusts the seat space by adjusting the distance between the front chassis and the rear chassis, the seat can be directly fixed relative to the rear chassis, so that no space needs to be reserved between the seat and other components behind it, and the overall structure is more compact.

[0009] In the aforementioned golf cart with adjustable front seat space, the drive component is an electric cylinder, with its two ends hinged to the front and rear chassis, respectively. This allows the electric cylinder to automatically adjust its angle during operation, resulting in smoother and more stable operation and preventing normal functioning from being affected by installation precision or minor deformations between the front and rear chassis.

[0010] In the aforementioned golf cart with adjustable front seat space, the front chassis has a mounting seat arranged along the length direction, the mounting seat has a mounting groove along the length direction, a sliding seat is fixed in each mounting groove, and a sliding groove is formed in each sliding seat. The rear chassis has a sliding rod corresponding to each mounting seat, one end of the sliding rod extends into the corresponding mounting seat and slides in cooperation with the sliding groove of the sliding seat.

[0011] In the aforementioned golf cart with adjustable front seat space, the mounting seats are arranged in two sets at intervals, and the electric cylinder is located between the two mounting seats.

[0012] In the aforementioned golf cart with adjustable front seat space, a sunshade bracket is provided between the front and rear chassis. The sunshade bracket includes a front bracket, a rear bracket, and a connecting frame. The lower end of the front bracket is fixed to the front chassis, and the lower end of the rear bracket is hinged to the rear chassis. Both ends of the connecting frame are hinged to the upper ends of the front and rear brackets, respectively, above the seat. This allows the sunshade to adjust automatically when the distance between the front and rear chassis is adjusted, avoiding interference.

[0013] In the aforementioned golf cart with adjustable front seat space, the lower end of the rear support has a guide plate with an arc-shaped guide groove, and the rear chassis is provided with a positioning pin for sliding engagement with the guide groove.

[0014] In the aforementioned golf cart with adjustable front seat space, the positioning pin is a fixing bolt threaded to the rear chassis. By tightening the bolt with a knob, the rear support can be locked after the seat space adjustment is completed, thereby improving the stability of the awning structure.

[0015] The aforementioned golf cart with adjustable front seat space also includes a safety mechanism with a control switch for controlling the on / off state of the control system. This safety mechanism ensures that the control system is activated before adjusting the seat space, preventing accidental activation or operational errors and thus enhancing safety.

[0016] In the aforementioned golf cart with adjustable front seat space, the control switch is a micro switch. The safety mechanism also includes a support base, a lever, and a spring. The lever is vertically movable and rotatably inserted into the support base. The spring is sleeved on the lever and used to push the lever downwards. The side wall of the support base has a vertically arranged guide groove and a positioning groove located on one side of the guide groove and communicating with the top of the guide groove. The micro switch is located below the positioning groove. One side of the lever has a positioning protrusion that slides with the guide groove and the positioning groove and can move between the guide groove and the positioning groove. After the positioning protrusion moves into the positioning groove, it can touch the contact of the micro switch. The safety mechanism adopts a foolproof design. When using it, the lever must first be pulled upwards and then rotated to move the positioning protrusion from the bottom of the guide groove into the positioning groove and trigger the micro switch to put the control system into working condition, thereby improving the reliability of the safety mechanism and preventing its accidental activation.

[0017] In the aforementioned golf cart with adjustable front seat space, the safety mechanism is located beneath the seat. This makes the safety mechanism more concealed, further preventing accidental activation.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] 1. The chassis of this utility model is composed of a front chassis and a rear chassis that slide together, and a drive component is set between the two to control the distance between them. By adjusting the distance between the front chassis and the rear chassis, the space between the seat on the rear chassis and the front chassis can be adjusted to accommodate people of different body types. Moreover, no space needs to be reserved between the seat and other components behind it, making the overall structure more compact.

[0020] 2. The sunshade of this utility model is composed of a front support, a rear support and a connecting frame that are hinged in sequence, so that it can adjust its angle automatically when the distance between the front chassis and the rear chassis is adjusted, thus avoiding interference.

[0021] 3. This utility model also includes a safety mechanism for controlling the circuit connection between the control system and the drive component. This mechanism is opened before each seat adjustment and closed after the adjustment, thus preventing accidental activation of the drive component and improving safety and reliability.

[0029] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0030] A golf cart with adjustable front seat space, such as Figures 1-3 As shown, the system includes a front chassis 1, a rear chassis 2, a drive unit, and a control system. In this embodiment, the front wheels, steering wheel, and center console are all mounted on the front chassis 1, while the rear wheels, power supply, and seat 4 are all mounted on the rear chassis 2. The front wheels are steering wheels, and the rear wheels are drive wheels driven by a motor. The front chassis 1 and the rear chassis 2 are slidably connected along the length of the vehicle body. The drive unit is connected to the front chassis 1 and the rear chassis 2 respectively and can drive the rear chassis 2 to move back and forth relative to the front chassis 1 under the control of the control system to adjust the space in front of the seat 4.

[0031] Specifically, such as Figure 3 , Figure 4As shown, the front chassis 1 has two spaced-apart mounting seats 11, each elongated and arranged along the length of the vehicle body. Each mounting seat 11 has a mounting groove 11a along its length, and a sliding seat 12 is fixed within each groove 11a by bolts. Each sliding seat 12 has a sliding groove along its length. The rear chassis 2 has two spaced-apart sliding rods 21, also arranged along the length of the vehicle body and corresponding one-to-one with the two mounting seats 11. Each sliding rod 21 extends into its corresponding mounting seat 11 and slides in cooperation with the sliding groove of the sliding seat 12, allowing the rear chassis 2 to move back and forth relative to the front chassis 1. In this embodiment, each mounting groove 11a contains two sliding seats 12 spaced apart along the length of the groove 11a to improve the stability of the sliding cooperation.

[0032] In this embodiment, the driving component is an electric cylinder 3, and the driving component and the rear wheel drive motor are powered by the same power source. The control system is connected to the electric cylinder 3 via a circuit, and the control switch of the control system is located on one side of the seat 4 so that the control system can control the operation of the driving component. Of course, in practical applications, the control switch of the control system can also be located on the center console. Figure 4 As shown, in this embodiment, the electric cylinder 3 is arranged between the two sliding seats 11 along the length of the vehicle body, and the two ends of the electric cylinder 3 are respectively hinged to the front chassis 1 and the rear chassis 2, so that the electric cylinder 3 can adaptively adjust when there is a certain deviation in the cooperation between the front chassis 1 and the rear chassis 2, making its operation more stable and reliable.

[0033] Furthermore, such as Figure 4 , Figure 5As shown, in this embodiment, a safety mechanism 5 is also provided on the rear chassis 2. The safety mechanism 5 has a control switch, which is electrically connected to the control system, enabling the safety mechanism 5 to control the opening and closing of the control system and avoid misoperation. Specifically, in this embodiment, the control switch is a micro switch 54. The safety mechanism 5 also includes a support base 51, a lever 52, and a spring 53. The support base 51 is fixed on the rear chassis 2. The lever 52 is vertically inserted into the support base 51, which can move up and down and rotate. The spring 53 is sleeved on the lever 52, and both ends of the spring 53 abut against the support base 51 and the lever 52 respectively, so that the spring 53 always pushes the lever 52 downward. The side wall of the support base 51 has a guide groove 51a and a positioning groove 51b. The guide groove 51a is arranged in the vertical direction, and the positioning groove 51b is located on one side of the top of the guide groove 51a and communicates with the guide groove 51a. The micro switch 54 is disposed in the positioning groove. Below 51b, one side of the lever 52 has an outwardly protruding positioning protrusion 521. The positioning protrusion 521 forms a sliding fit with the guide groove 51a and the positioning groove 51b, so that the positioning protrusion 521 can move between the guide groove 51a and the positioning groove 51b when the lever 52 is turned. When the positioning protrusion 521 is embedded in the positioning groove 51b, the positioning protrusion 521 can contact the contact of the micro switch 54 and put the micro switch 54 in the conducting state. Conversely, when the positioning protrusion 521 leaves the positioning groove 51b and is located at the bottom of the guide groove 51a under the action of the spring 53, the positioning protrusion 521 does not contact the contact of the micro switch 54, and the micro switch 54 is in the open circuit state. In this way, before each adjustment of the seat 4 space, the user must first move the positioning protrusion 521 into the positioning groove 51b using the lever 52 to turn on the control system, and then control the drive component to work through the control system. After the adjustment is completed, the positioning protrusion 521 is moved back to the bottom of the guide groove 51a to avoid misoperation.

[0034] To further prevent accidental activation, in this embodiment, the safety mechanism 5 is located below the seat 4.

[0035] Furthermore, such as Figure 5 As shown, a bending member 13 is also fixed on the front chassis 1. The bending member 13 is fixed to the rear end of one of the mounting seats 11 by welding. The bending member 13 has an insertion hole. When the electric cylinder 3 moves to its maximum stroke position, which is the space size of the seat 4 recommended by this utility model, the lower end of the lever 52 extends out of the bottom of the support seat 51 and inserts into the insertion hole of the bending member 13 when the positioning protrusion 521 is located at the bottom of the guide groove 51a.

[0036] like Figure 2As shown, a sunshade 6 bracket is also provided between the front chassis 1 and the rear chassis 2. The sunshade 6 bracket includes a front bracket 61, a support bracket, and a connecting frame 63. The lower end of the front bracket 61 is fixedly connected to the front chassis 1, and the lower end of the rear bracket 62 is hinged to the rear chassis 2. The two ends of the connecting frame 63 are respectively hinged to the upper ends of the front bracket 61 and the rear bracket 62 above the seat 4, so that the sunshade 6 can adaptively adjust when adjusting the space of the seat 4, avoiding interference. In this embodiment, the connecting frame 63 consists of two long rods spaced apart.

[0037] like Figure 6 As shown, both sides of the lower end of the rear support 62 are hinged to the rear chassis 2, and both sides of the lower end of the rear support 62 have guide plates 621. Each guide plate 621 has an arc-shaped guide groove 622 centered on the hinge point. Correspondingly, the rear chassis 2 has two positioning pins that correspond one-to-one with the guide grooves 622. The positioning pins are embedded in the corresponding guide grooves 622 and slide in cooperation with them to improve the stability of the rear support 62 when it swings. Furthermore, in this embodiment, one of the positioning pins is a fixing bolt 623 threaded to the rear chassis 2, so that the fixing bolt 623 can act as both a positioning pin and a locking element. When adjusting the seat 4, the fixing bolt 623 is loosened to facilitate the swinging and angle adjustment of the rear support 62. After the seat 4 is adjusted, the fixing bolt 623 is tightened to fix the rear support 62 relative to the rear chassis 2, thereby improving the overall structural stability of the sunshade 6.

[0038] Furthermore, in this embodiment, the seat 4 adopts a double seat 4 structure arranged back to back, and a pedal 7 is provided at the rear of the rear chassis 2 for cooperating with the rear seat 4.

[0039] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0040] Although this document frequently uses terms such as front chassis 1, mounting base 11, sliding base 12, rear chassis 2, slide bar 21, electric cylinder 3, seat 4, micro switch 54, and sunshade 6, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
