Description

Technical Field

[0001] This utility model relates to the field of windshield lifting technology, specifically to an intelligent temperature-controlled lifting system for a vehicle's front windshield. Background Technology

[0002] Currently, most golf carts (or similar in-field sightseeing and inspection vehicles) on the market are equipped with windshields. Their main function is to provide basic wind and sun protection for the driver and passengers during travel. Traditional windshields mostly use manual folding or lifting mechanisms, requiring users to manually adjust their opening and closing status according to weather conditions and personal preference. For example, in hot weather, users need to manually lower the windshield to allow airflow for ventilation and cooling; while when the temperature drops or the wind speed is high, they need to manually raise it to avoid cold air blowing directly on them.

[0003] However, this manual operation-dependent model has significant shortcomings: First, it requires active intervention from the driver or passengers, and frequent operation during driving may distract attention and affect driving safety; second, users may not be able to maintain a consistently comfortable in-vehicle environment due to failure to promptly perceive temperature changes or temporary inconvenience, thus reducing the driving and riding experience. This is especially true in long-duration outdoor golf courses where ambient temperature changes rapidly, making the lag and inconvenience of manual adjustment even more pronounced. Utility Model Content

[0004] To address the technical problems mentioned above, this utility model provides an intelligent temperature control lifting system for a vehicle windshield.

[0005] The technical solution of this utility model is as follows: A vehicle windshield intelligent temperature control lifting system includes a vehicle body, a windshield frame is provided at the front of the vehicle body, a first windshield and a second windshield are provided on the windshield frame, guide grooves are provided on opposite sides of the windshield frame, and a lifting drive assembly is connected to the second windshield, the lifting drive assembly drives the second windshield to slide in the guide groove. It also includes a lifting control component, which is electrically connected to the lifting drive component.

[0006] The lifting drive assembly includes a first electric push rod, a pulley system, and a pull rope. The pulley system and the first electric push rod are connected to the vehicle body, and the first electric push rod is arranged laterally. One end of the pull rope is connected to the second windshield through the pulley system, and the other end is connected to the movable end of the first electric push rod.

[0007] The first electric push rod is configured as one, horizontally positioned above the windshield frame. Two pull ropes are configured, each connected to one side of the second windshield and then guided by a pulley system to the movable end of the first electric push rod.

[0008] The lifting drive assembly includes two electric gears and two racks. The electric gears are located on both sides of the vehicle body and drive the racks to lift and lower. The two racks are connected to both sides of the second windshield, allowing the second windshield to slide within the guide groove.

[0009] The lifting drive assembly includes two second electric push rods, which are vertically arranged on both sides of the vehicle body. The lower ends of the two second electric push rods are connected to both sides of the second windshield, and the upper ends are connected to the vehicle body, so that the second windshield slides in the guide groove.

[0010] The lifting control component includes a relay and a temperature controller.

[0011] The relay is a DC 12V, 8-pin relay.

[0012] The relay has normally open pins 1 and 2, normally closed pins 3 and 4, power supply pins 5 and 6, and coil pins 7 and 8.

[0013] The temperature controller is electrically connected to the relay coil pin.

[0014] When the temperature received by the temperature controller is below 30 degrees Celsius, there is no electrical signal at the relay coil pin; when the temperature received by the temperature controller is greater than or equal to 30 degrees Celsius, an electrical signal is sent to the relay coil pin.

[0015] This invention introduces temperature-sensing-based automatic control technology to intelligently improve the windshield lifting mechanism of golf carts, offering the following significant advantages compared to the traditional manual mode: This invention uses a temperature sensor to monitor the ambient temperature in real time and drives the actuator to control the raising and lowering of the windshield, achieving automatic adjustment and improving the ease of operation and safety. When the ambient temperature rises to a set threshold, the system automatically lowers the glass to provide ventilation, and when the temperature drops, it automatically rises to block the wind. The whole process reduces manual intervention, frees the driver's hands, avoids the safety risks caused by manual operation while driving, and greatly facilitates the driver's use.

[0016] This utility model system can respond quickly and accurately to changes in ambient temperature, ensuring that the vehicle interior is always in a good state of ventilation or heat preservation. When the temperature is high, it automatically introduces natural wind to effectively reduce the feeling of stuffiness. When the temperature is low or the wind speed is high, it automatically forms a wind resistance barrier to protect passengers from direct cold wind, thereby significantly improving the driving and riding comfort under different weather conditions.

[0017] This utility model improves and optimizes the overall vehicle technology and intelligence level, upgrading a simple mechanical structure into an intelligent temperature control system. It reflects the technological progress in vehicle intelligence and automation, helps to enhance product added value and market competitiveness, and is in line with current technological development trends.

[0018] The solution of this utility model is suitable for various indoor sightseeing and inspection vehicles, especially golf carts, and can also be applied to any other open or closed vehicle with heating and cooling requirements. Attached Figure Description

Detailed Implementation

[0021] Example 1 See Figure 1 and Figure 2 A vehicle windshield intelligent temperature control lifting system includes a vehicle body, taking a golf cart as an example. A windshield frame 1 is provided at the front of the vehicle body. A first windshield 2 and a second windshield 3 are provided on the windshield frame 1. A guide groove 4 is provided on the opposite side of the windshield frame 1. The second windshield 3 is connected to a lifting drive assembly 5, which drives the second windshield 3 to slide within the guide groove 4.

[0022] It also includes a lifting control component, which is electrically connected to the lifting drive component 5.

[0023] In this embodiment, the windshield frame 1 is tilted upwards. Golf carts and similar vehicles used for sightseeing and inspection often employ this upward-tilted design for their windshields, representing an optimized solution integrating aerodynamics, safety, and ergonomics. Its core advantages lie in significantly reducing air resistance during driving, improving energy efficiency and stability; the tilted surface effectively deflects flying debris and works in conjunction with the vehicle structure to enhance protection during collisions. Simultaneously, this design helps reduce glare in the cockpit caused by sunlight reflection and naturally aligns with the driver's field of vision, improving the visibility of the road ahead. Furthermore, the tilted surface facilitates rainwater runoff, keeping the glass clean. Therefore, this streamlined design is a key element in achieving vehicle efficiency, safety, and comfort.

[0024] The lifting drive assembly 5 includes a first electric push rod 501, a pulley block 502, and a pull rope 503. The pulley block 502 and the first electric push rod 501 are connected to the vehicle body. The first electric push rod 501 is arranged laterally. One end of the pull rope 503 is connected to the second windshield 3 through the pulley block 502, and the other end is connected to the movable end of the first electric push rod 501.

[0025] Specifically, as a basic structure of the vehicle body, the front end of the vehicle body includes two A-pillars arranged opposite each other and a roof at the top of them. In this embodiment, the first electric push rod 501 is set above the windshield frame 1 by fasteners, specifically between the two A-pillars and inside the roof. The pulley group 502 is also connected near the A-pillar and fixed to the A-pillar or the roof, so that the pull rope 503 can be easily attached.

[0026] In this embodiment, in order to set the first electric push rod 501 laterally to save space inside the vehicle, a pulley block 502 and a pull rope 503 are provided for guidance.

[0027] Preferably, such as Figure 1 and Figure 2 As shown, there is one first electric push rod 501 and two pull ropes 503. The two pull ropes 503 are respectively connected to both sides of the second windshield 3, and are connected to the movable end of the first electric push rod 501 after being guided by the pulley group 502. The connection method between the pull ropes 503 and the sides of the second windshield 3 is not limited; they can be threaded through or connected by fasteners.

[0028] In this embodiment, to simultaneously drive the pull ropes 503 on both sides of the second windshield 3 to rise and fall using the first electric push rod 501, the pulley assembly 502 includes three pulleys: a first pulley 5021, a second pulley 5022, and a third pulley 5023. The first pulley 5021 is positioned away from the movable end of the first electric push rod 501, its purpose being to pull one of the pull ropes 503 towards the movable end of the first electric push rod 501. The second pulley 5022 is positioned close to the movable end of the first electric push rod 501, its purpose being to pull the other pull rope 503 towards the movable end of the first electric push rod 501, facilitating its connection to the movable end of the first electric push rod 501. The third pulley 5023 is positioned close to the movable end of the first electric push rod 501, its purpose being to facilitate the connection of the pull rope 503 pulled by the first pulley 5021 to the movable end of the first electric push rod 501. Figure 2 It helps with understanding.

[0029] In this embodiment, the first electric push rod 501 is a known standard device, including a motor, a transmission component, a lead screw, and a telescopic tube. The telescopic tube is sleeved outside the lead screw, and its end is connected to the pull rope 503. The lead screw is connected to the motor through the transmission component. When the motor rotates forward, the telescopic tube retracts; when the motor rotates in reverse, the telescopic tube extends. As the first electric push rod 501 is a standard device, it is only necessary to select a suitable commercially available model according to the glass lifting stroke, which will not be described in detail here.

[0030] Lifting process: When the temperature sensor detects a low temperature, the lifting drive component 5 receives a lifting command. The lifting control component sends a forward rotation signal to the motor, which starts and drives the telescopic tube to retract, starting to tighten the pull rope 503. The pull rope 503 generates tension, which acts on the upper edge or connection point of the second windshield 3. Under the traction of the pull rope 503 and the constraint of the guide grooves 4 on both sides, the second windshield 3 slides smoothly upward along the guide grooves 4 until it reaches the preset top position, at which point the motor stops working.

[0031] Descent Process: A temperature sensor detects a high temperature, triggering a descent command to the lifting drive assembly 5. The lifting control assembly sends a reverse signal to the motor, causing it to rotate in the opposite direction. This extends the telescopic tube. Normally, the weight of the second windshield 3 itself is sufficient to lower it naturally. The main purpose of reversing the motor is to release the constraint on the pull cord 503, allowing the glass to slide down under gravity—an energy-saving design.

[0032] Additionally, it is worth noting that, in order to ensure a smooth descent and avoid impacts, the motor can provide slight damping or perform inching control when reversing, ensuring that the glass descends at a uniform speed until it reaches the preset bottom position.

[0033] The lifting control components in this embodiment include a relay and a temperature controller, both of which are commercially available components that can be placed or fixed in any position inside the vehicle. In this embodiment, they are preferably placed in the dashboard position inside the vehicle.

[0034] As an example rather than a limitation, the relay is a DC 12V, 8-pin relay. The temperature controller selection only needs to cover the ambient temperature range, which is the most common temperature control component.

[0035] In this embodiment, relay pins 1 and 2 are normally open, pins 3 and 4 are normally closed, pins 5 and 6 are power supply pins, and pins 7 and 8 are coil pins. This design achieves strong and weak current isolation, providing high safety, which is one of the most critical advantages. The temperature controller is a low-voltage, low-current weak current control circuit, while the motor circuit is a high-current 12V DC circuit. The relay plays an isolation role here. The temperature controller only needs a very small current to drive the relay coil's weak current side, and the relay then controls the switching on and off of the motor's high-current strong current side. This effectively protects the precision and expensive temperature controller from damage caused by the surge current and electromagnetic interference generated during motor operation, greatly improving the system's stability and lifespan.

[0036] Preferably, the temperature controller is electrically connected to the relay coil pin.

[0037] When the temperature received by the temperature controller is below 30 degrees Celsius, there is no electrical signal at the relay coil pin.

[0038] Specifically, the relay coil pins are not energized, and the internal switch remains in its normal position, i.e., the normally closed contact is closed. At this time, pins 3 and 4 of the relay are connected. Assuming the circuit is designed such that when pins 3 and 4 are connected, the motor power supply is connected in the direction that makes the motor rotate forward or keep it in the raised state, then the motor drives the telescopic rod to pull the rope 503, raising the second windshield 33 to the top and holding it in that position.

[0039] When the temperature received by the temperature controller is greater than or equal to 30 degrees, it sends an electrical signal to the relay coil pin.

[0040] Specifically, when the relay coil is energized, it generates a magnetic field, which activates the internal switch, causing a state switch, i.e., the normally open contact closes. At this time, pins 1 and 2 of the relay become closed, while pins 3 and 4 are open, and the circuit switches to the loop containing pins 1 and 2. Assuming this loop is designed to reverse the motor, the telescopic rod releases the pull rope 503, and the second windshield 3 descends smoothly along the guide groove 4 under its own weight, achieving ventilation.

[0041] In summary, this embodiment has made intelligent improvements to the windshield raising and lowering mechanism of the golf cart by introducing temperature-sensing-based automatic control technology. Compared with the traditional manual mode, it has the following significant advantages: By monitoring the ambient temperature in real time with a temperature sensor and driving the actuator to control the raising and lowering of the windshield, intelligent adjustment is achieved, improving the convenience and safety of operation. When the ambient temperature rises to the set threshold, the system automatically lowers the glass to achieve ventilation; when the temperature drops, it automatically rises to block the wind. The whole process reduces manual intervention, frees the driver's hands, avoids the safety risks caused by manual operation while driving, and greatly facilitates the use of the vehicle.

[0042] The system in this embodiment can respond quickly and accurately to changes in ambient temperature, ensuring that the vehicle interior is always well-ventilated or kept warm. When the temperature is high, it automatically introduces natural wind to effectively reduce stuffiness. When the temperature is low or the wind speed is high, it automatically forms a wind resistance barrier to protect passengers from direct exposure to cold wind, thereby significantly improving driving comfort under different weather conditions.

[0043] The improvement in this embodiment upgrades the simple mechanical structure into an intelligent temperature control system, reflecting our company's technological progress in vehicle intelligence and automation. This helps to enhance product added value and market competitiveness, and is in line with current technological development trends.

[0044] Example 2 The only difference between this embodiment and Embodiment 1 is that two first electric push rods 501 are provided. The two first electric push rods 501 are located in the same position as the first electric push rods 501 in Embodiment 1, but their movable ends face opposite directions. In this way, the pulley group 502 only needs two pulleys, which are respectively set on both sides of the movable ends. The movable ends of the two first electric push rods 501 are each connected to a pull rope 503 to connect to both sides of the second windshield 3 and are guided by the two pulleys.

[0045] Furthermore, when the first electric push rod 501 becomes two, they only need to be connected in parallel with the relays described earlier to work synchronously; this is basic electrical knowledge. The solution in this embodiment is relatively simple and will not be illustrated further. This solution reduces the number of pulleys and the length of the pull rope, but the increase in the number of electric push rods increases the lateral space occupied; the choice can be made based on the specific space available in the vehicle.

[0046] Example 3 Unlike Embodiment 1, considering the high precision, high strength and self-locking capability brought by rigid transmission, the lifting drive assembly 5 is designed as a gear and rack transmission structure.

[0047] See Figure 3The lifting drive assembly 5 includes an electric gear 504 and a rack 505, both of which are commercially available components, as long as they meet the requirements for glass lifting stroke.

[0048] like Figure 3 As shown, the electric gears 504 are mounted on both sides of the vehicle body. The simplest way is to directly install them onto the inside of the A-pillar via their own motor mounts, fixing them to the A-pillar or roof (not shown in the figure due to view limitations). The two racks are connected to both sides of the second windshield 3 by fasteners or adhesives, or any other means. In this way, the electric gears 504 drive the racks 505 to rise and fall. The racks 505 are connected to the second windshield 3, allowing the second windshield 3 to slide within the guide grooves 4.

[0049] The meshing transmission between the electric gear 504 and the rack 505 exhibits almost no elastic deformation, resulting in linear and continuous motion. This makes the raising and lowering of the second windshield 3 very smooth, without shaking or wobbling, and enables better position control. Similarly, when there are two electric gears 504, they can be connected in parallel with the relays described earlier for synchronous operation, which is basic electrical knowledge.

[0050] Example 4 See Figure 4 and Figure 5 Unlike Embodiment 1, this embodiment is a simpler implementation. The lifting drive assembly 5 uses two vertical electric push rods, which are defined here as the second electric push rods. The two second electric push rods are vertically arranged on both sides of the vehicle body. The upper end can be directly connected to the roof of the vehicle body, and the lower end, i.e. the telescopic end, is connected to both sides of the second windshield 3, so that the second windshield 3 slides in the guide groove 4.

[0051] Similarly, the second electric push rod can be selected from commercially available products based on the glass lifting stroke. When there are two second electric push rods, they can be connected in parallel with the relays introduced earlier to work synchronously, which will not be elaborated further.

[0052] Compared with Embodiment 1, using the movable end of the electric push rod as the lifting drive component 5 directly not only avoids the use of pulleys and rope guides in Embodiment 1, but also improves rigidity control capabilities and can provide more direct push and pull forces. This means that it can not only raise the second windshield 3, but also actively and powerfully push the glass down instead of relying on gravity, thus reducing sliding and jamming.

[0053] This is particularly effective for heavier, larger windshields, or in situations where strong crosswinds require the glass to be forcibly closed to ensure a tight seal. It can overcome resistance and ensure that the second windshield 3 is raised or lowered to the target position.

[0054] The above description is merely a preferred embodiment of this utility model. Modifications to these embodiments without departing from the concept of this patent will be readily apparent to those skilled in the art. Therefore, the scope of protection of this utility model should be determined by the claims.
