Abstract
Description
Technical Field
[0001] This utility model relates to the field of ergonomics of industrial vehicles, and more specifically, it relates to a heated handle for industrial vehicles. Background Technology
[0002] Due to limitations in the use of industrial vehicles and available space, some industrial vehicle operators need to operate them in an open environment in order to obtain a better field of vision.
[0003] When operators take industrial vehicles outdoors in low temperatures, they are more susceptible to the effects of the cold, which can affect the precision of vehicle operation and make the work more difficult. Operators must wear a lot of clothing to keep warm. Wearing gloves and other clothing can further affect the precision of vehicle operation.
[0004] Therefore, this application aims to provide a heated handle for industrial vehicles with a heating function, which can provide heating for the handle and maintain a constant temperature of the handle, thereby adapting to different heat loss environments when the vehicle enters and exits indoors and outdoors and when driving outdoors. Utility Model Content
[0005] This invention overcomes the shortcomings of existing industrial vehicles that require gloves to operate outdoors, which affects the precision of vehicle operation. It provides a heated handle for industrial vehicles that can provide heating and maintain a constant temperature, thus adapting to different heat loss environments when vehicles are moving indoors or outdoors and when driving outdoors.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0007] A heated handle for industrial vehicles includes a handle body and a grip disposed on the handle body. The grip has a grip frame, a heating layer and an outer sheath from the inside to the outside. A first temperature sensor and a second temperature sensor are respectively disposed on the outer sheath and the handle body. A microcontroller and a control button are disposed on the handle body. The microcontroller is electrically connected to the first temperature sensor, the second temperature sensor, the heating layer and the control button. The controller controls the power of the heating layer in a closed loop through the first temperature controller and the second temperature controller.
[0008] The operator manipulates the industrial vehicle using a handle. To adapt to outdoor work, a heating layer is installed at the point of contact with the operator's palm. The heat generated by the heating layer is transferred to the outer sheath, increasing the temperature at the point of contact with the operator, protecting the operator's hands, and preventing the operator's hand precision from being affected by cold.
[0009] An outer sheath is installed on the outside of the heating layer to protect it and prevent it from direct contact with the external environment.
[0010] The heating layer adjusts its power by regulating the incoming current. The controller controls the current of the heating layer, and the controller adjusts the current based on the external environment and the handle temperature. According to the preset temperature, the controller collects the temperature information generated by the first temperature sensor as the handle temperature and collects the temperature of the second temperature sensor as the external temperature. The controller uses the difference between the external temperature and the internal temperature as the basis for controlling the current and performs closed-loop power control through a PID algorithm, thereby stabilizing the temperature within a small fluctuation range.
[0011] Preferably, the handle body includes a central post and two horn-shaped rods, with the grips mounted on the horn-shaped rods.
[0012] Preferably, the handle is shaped to fit the hand. This design is ergonomic, improving the feel and precision of operating industrial vehicles.
[0013] Preferably, the heating layer is adhered to the surface of the grip, with a coverage rate of over 90%. Combined with the aforementioned ergonomic design of the grip, the structure can fully contact the palm and effectively heat it.
[0014] Preferably, the surface of the outer sheath is textured with friction patterns. The friction patterns increase the friction between the operator and the outer sheath.
[0015] Preferably, the heating layer is a carbon fiber heating element. The carbon fiber material, cut to fit the grip frame, is hot-pressed onto the handle frame to achieve high coverage.
[0016] Preferably, an epoxy resin insulation layer is also provided between the carbon fiber heating element and the handle. This insulation layer prevents short circuits and leakage.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] (1) The carbon fiber heating element is covered with a high coverage area on the handle frame, achieving near full-area heating at the point of contact with the palm, bringing a good user experience;
[0019] (2) The direct heating of the handle allows the operator's palm to directly or while wearing thin gloves to touch the handle, resulting in a better operating feel;
[0020] (3) Closed-loop control is performed by temperature sensors set on the handle body and the outer sheath to maintain low temperature fluctuations on the handle. Attached Figure Description

[0031] Example:
[0032] A heating handle for industrial vehicles includes a handle body 1 and a grip 2 disposed on the handle body 1. The handle body 1 includes a central post 3 and two horn rods 4, and the grip 2 is disposed on the horn rods 4.
[0033] The handle 2 comprises a handle frame 5, a heating layer 10, and an outer sheath 6 from the inside out. A first temperature sensor 7 and a second temperature sensor 8 are respectively mounted on the outer sheath 6 and the handle body 1. The first temperature sensor 7 is located in the center of the outer sheath 6, while the second temperature sensor 8 is located on the handle body 1 away from the operator. When operating an industrial vehicle, which is moving against the wind, the second temperature sensor 8, positioned away from the operator on the handle body 1, better reflects the actual operating environment. The first temperature sensor 7, located at the edge of the outer sheath 6, is covered by the operator's hand, thus detecting the temperature felt by the hand.
[0034] The handle body 1 is equipped with a microcontroller and a control button. The microcontroller is electrically connected to the first temperature sensor 7, the second temperature sensor 8, the heating layer 10 and the control button. The controller controls the power of the heating layer 10 in a closed loop through the first temperature controller and the second temperature controller.
[0035] The handle 2 is ergonomically designed to fit the shape of the hand. This structure improves the feel and precision of operating industrial vehicles. A heating layer 10 adheres to the surface of the handle 2, covering over 90% of its surface. Combined with the aforementioned ergonomic design of the handle 2, this structure allows for full contact with the palm, providing ample heating.
[0036] The outer sheath 6 is made of plastic, and its surface has friction texture 9. The friction texture 9 increases the friction between the operator and the outer sheath 6.
[0037] The heating layer 10 is a carbon fiber heating element. The carbon fiber material, cut to fit the handle frame 5, is hot-pressed onto the handle frame to achieve high coverage. Specifically, the conditions are 80-100℃ and 5-10MPa. An insulating layer 11, made of epoxy resin, is also provided between the carbon fiber heating element and the handle 2. This insulating layer 11 prevents short circuits and leakage.
[0038] The control buttons are used to switch temperature settings, which can be 35℃, 40℃, and 45℃. Switching between different settings is achieved by short presses, while long presses are used to display the cause of the fault. The controller is also connected to LEDs, which display different errors with corresponding colors or flashing frequencies.
[0039] The operator operates the industrial vehicle via a handle. To adapt to outdoor work, a heating layer 10 is installed at the point of contact with the operator's palm. The heat generated by the heating layer 10 is transferred to the outer sheath 6, increasing the temperature at the point of contact with the operator, protecting the operator's hands, and preventing the operator from affecting the precision of their operation due to cold.
[0040] An outer sheath 6 is provided on the outside of the heating layer 10 to protect the heating layer 10 and prevent the heating layer 10 from directly contacting the external environment.
[0041] The heating layer 10 adjusts its power by regulating the incoming current. The controller controls the current of the heating layer 10. The controller adjusts the current based on the external environment and the handle temperature. According to the preset temperature, the controller collects the temperature information generated by the first temperature sensor 7 as the handle temperature and collects the temperature of the second temperature sensor 8 as the external temperature. The controller uses the difference between the external temperature and the handle temperature as the basis for controlling the current and performs closed-loop power control through a PID algorithm, thereby stabilizing the temperature within a small fluctuation range.
[0042] The external temperature is Tenv, and the handle temperature is Tsurf. When Tenv is below 5 degrees Celsius, a PID algorithm is activated to dynamically adjust the power of heating layer 10, satisfying the following conditions:
[0043]
[0044] PID parameters , , According to the vehicle power supply voltage fluctuation range (20V-30V).
[0045] Based on this, the controller has a built-in or external ammeter. According to the current value provided by the ammeter, the controller triggers overcurrent protection and cuts off the heating power supply.
[0046] Similarly, the controller is also equipped with over-temperature protection based on the handle temperature. When the handle temperature exceeds 50 degrees Celsius, the heating power is cut off.
[0047] The embodiments described above are merely preferred solutions of this utility model and are not intended to limit this utility model in any way. Other variations and modifications are possible without departing from the technical solutions described in the claims.
