Description

Technical Field

[0001] This utility model relates to a power-assisted vehicle, and more particularly to an electric handcart. Background Technology

[0002] Electric handcarts are widely used in agriculture, logistics, sanitation, and other fields. Their structure typically includes a frame, cargo box, power unit, and handlebar assembly. Existing electric tricycles can cause discomfort for users holding the handlebars in cold environments, even affecting operational safety. Currently, there are no mature electric tricycles on the market equipped with heated handlebars, requiring users to wear gloves or other warm clothing, which reduces operational flexibility and comfort. Utility Model Content

[0003] The purpose of this invention is to provide an electric handcart that solves the above-mentioned problems and achieves the effect of heating the handlebars of the electric vehicle.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an electric handcart, comprising a cart body, a drive unit disposed on the cart body, an active wheel driven by the drive unit and rotatably connected to the cart body, a passive wheel rotatably connected to the cart body, a battery unit supplying power to the drive unit, and a handle assembly disposed at one end of the cart body. The handle assembly includes a handle body, a heating element disposed on the handle body, and an insulating protective sleeve covering the outer sides of the handle body and the heating element.

[0005] After adopting the above technical solution, the present invention has the following advantages: The heating element is located on the handle body, and heat is transferred to the surface of the handle body through the heating wire, so that the user can hold the handle body in a cold environment without hand discomfort. The handle body and the heating element are covered with an insulating protective sleeve. The insulating protective sleeve not only prevents the user from directly contacting the heating element and avoiding high temperature burns, but also protects the heating element from direct contact with dust or friction with the hand, especially the damage caused by the complex outdoor working environment of the electric handcart. Therefore, the setting of the insulating protective sleeve extends the service life of the heating element.

[0006] Furthermore, the heating element is a heating wire, which is spirally arranged on the outside of the handle body.

[0007] Using the aforementioned technical solution, the heating wire is spirally wound around the outside of the handle body. Compared to other arrangement methods, the spiral structure ensures that the heating area of ​​the handle body is continuously distributed along the length of the handle. Because heat is evenly conducted along the spiral path, local overheating or cold areas are avoided, ensuring temperature consistency throughout the grip area and improving comfort.

[0008] Furthermore, the outer side of the handle body is provided with a spiral-shaped receiving groove for accommodating the heating wire, which is embedded in the receiving groove.

[0009] Using the aforementioned technical solution, if the heating wire is directly installed on the outside of the handle body, the heating wire may deform or even break due to compression when installing the insulating protective sleeve. However, by embedding the heating wire inside the handle body, the heating wire is recessed into the handle body. When installing the insulating protective sleeve, it only covers the outer surface of the handle body and does not directly compress the heating wire. This protects the heating wire, simplifies the assembly process, and ensures that the outer surface of the handle body remains flat and without protrusions after the heating wire is embedded, resulting in a tighter fit of the insulating protective sleeve and a better overall grip.

[0010] Furthermore, it includes a controller for driving the handle assembly and a battery compartment for housing the battery unit, with the heating element electrically connected to the controller and powered by the battery unit.

[0011] By adopting the aforementioned technical solution, the heating element and the controller share the same battery unit for power supply, eliminating the need for a separate battery or external power supply for the heating function. This reduces the number of circuit connection points and makes the electrical connection of the electric handcart simpler and more reliable.

[0012] Furthermore, the handle assembly is equipped with a temperature control element, which is electrically connected to the controller and powered by the battery unit. The temperature control element is used to regulate the temperature of the heating element.

[0013] By adopting the aforementioned technical solution, the temperature control component allows users to easily adjust the temperature of the handle assembly to a suitable temperature, which, compared to a fixed temperature, meets the needs under different ambient temperatures.

[0014] Furthermore, the temperature control component is equipped with a temperature sensor, which includes a temperature measuring end that extends into the insulating protective sleeve to transmit the temperature of the insulating protective sleeve to the temperature control component.

[0015] Using the aforementioned technical solution, the temperature sensor can transmit the real-time temperature of the insulating protective sleeve to the temperature control component. Furthermore, the sensing end extends directly into the insulating protective sleeve, forming physical contact with the heating element, allowing for real-time acquisition of the heating element's true temperature data. Compared to external indirect temperature measurement methods, this direct contact detection avoids interference from ambient temperature.

[0016] Furthermore, a screen is provided to allow users to easily view the temperature of the handle itself.

[0017] Using the aforementioned technical solution, users can conveniently monitor the handle temperature in real time via a screen.

[0018] Furthermore, the handle assembly has two handle bodies, each of which is equipped with a heating element, and the heating elements of both handle bodies are connected to a temperature control element.

[0019] Using the aforementioned technical solution, the temperature of the two handle bodies is regulated by the same control system. Users can set the target temperature through the control system to achieve constant temperature control of the two handle bodies.

[0020] Furthermore, the battery compartment is located between the two handle bodies. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0026] The terms "first," "second," etc. (if present) in the specification and claims of this utility model are used to distinguish similar objects, not to describe a specific order or sequence. Even if "second" is used before a technical feature for distinction, it does not necessarily imply the presence of "first." It should be understood that in this utility model, "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. It should be understood that in this utility model, "multiple" refers to two or more. "And / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, X and / or Y can represent: X alone, X and Y simultaneously, and Y alone. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. "Containing X, Y, and Z," "Containing X, Y, and Z" means that all three X, Y, and Z are included; "Containing X, Y, or Z" means that one of X, Y, and Z is included; "Containing X, Y, and / or Z" means that any one, two, or three of X, Y, and Z are included.

[0027] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0028] like Figure 1 As shown, this utility model provides an electric handcart, including a cart body, a drive unit disposed on the cart body, an active wheel driven by the drive unit and rotatably connected to the cart body, a passive wheel rotatably connected to the cart body, a battery unit that supplies power to the drive unit, and a handle assembly disposed at one end of the cart body. The handle assembly 1 includes a handle body 11, a heating element 12 fixed to the handle body 11, and an insulating protective sleeve 13 covering the outer sides of the handle body 11 and the heating element 12.

[0029] Understandably, the heating element 12 is located on the handle body 11. It transfers heat to the surface of the handle 1 through the heating wire, so that the user can hold the handle body 11 in cold environments without hand discomfort. The handle body 11 and the heating element 12 are covered with an insulating protective sleeve 13. The insulating protective sleeve 13 not only prevents the user from directly contacting the heating element 12 to avoid high temperature burns, but also protects the heating element 12 from direct contact with dust or friction with the hand, especially the damage caused by the complex outdoor working environment of the electric handcart. Therefore, the setting of the insulating protective sleeve 13 extends the service life of the heating element 12.

[0030] The heating element 12 is preferably a heating wire, which is spirally arranged on the outside of the handle body 11. A spiral-shaped receiving groove is provided on the outside of the handle body 11 to accommodate the heating wire, which is embedded within the groove. The heating wire is spirally wound around the outside of the handle body 11. Compared to other arrangements, the spiral structure ensures that the heating area of ​​the handle body 11 is continuously distributed along its length. Because heat is evenly conducted along the spiral path, localized overheating or cold spots are avoided, ensuring temperature consistency throughout the grip area and improving comfort. Furthermore, embedding the heating wire within the handle body 11 allows it to sink into the interior of the handle body 11. When the protective sleeve 13 is installed, it only covers the outer surface of the handle body 11 and does not directly compress the heating wire, protecting it and simplifying the assembly process. Moreover, after the heating wire is embedded, the outer surface of the handle body 11 remains flat without any protruding structures, allowing the insulating protective sleeve 13 to fit more tightly, resulting in a better overall grip.

[0031] The aforementioned insulating protective sleeve 13 is made of insulating soft silicone material.

[0032] It should be noted that the electric trolley includes a controller for driving the handle assembly 1 and a battery compartment 2 for accommodating the battery unit. The heating element 12 is electrically connected to the controller and powered by the battery unit. The heating element 12 and the controller share the same battery unit for power supply, eliminating the need for a separate battery or external power supply for the heating function. This reduces the number of circuit connection points and makes the electrical connection of the electric trolley simpler and more reliable.

[0033] In addition, the controller can automatically adjust the heating power according to the battery cell's charge level. When the battery cell's charge level is lower than a set threshold, the controller will turn off the heating function to ensure the vehicle can run normally.

[0034] In this embodiment, the threshold is set to 30% of the battery charge. That is, when the battery charge is less than or equal to 30%, the controller turns off the heating function of the heating element 12.

[0035] Alternatively, when the battery cell charge is less than or equal to 50%, the controller will automatically reduce the heating temperature of the heating element 12, that is, reduce the heating power to ensure the normal operation of the electric handcart.

[0036] To facilitate users in adjusting the temperature of the handle body 11 to a suitable temperature, the handle assembly 1 is provided with a temperature control component 14. The temperature control component 14 is electrically connected to the controller and powered by the battery unit. The temperature control component 14 is used to adjust the temperature of the heating element 12.

[0037] Generally speaking, the temperature range set by the temperature control component 14 is from 10℃ to 45℃, with the upper limit set to no more than 45℃, to prevent the user from being burned by excessively high temperatures.

[0038] A temperature sensor 141 is added to the temperature control component 14. The temperature sensor 141 includes a temperature measuring end that extends into the insulating protective sleeve 13 to transmit the temperature of the insulating protective sleeve 13 to the temperature control component 14.

[0039] By setting a temperature sensor 141, the real-time temperature of the handle body 11 can be transmitted to the temperature control component 14, and the temperature measuring end extends directly into the insulating protective sleeve 13, forming physical contact with the heating element 12, thus obtaining the real-time temperature data of the heating element 12. Compared with external indirect temperature measurement methods, this direct contact detection avoids interference from ambient temperature.

[0040] Furthermore, the heating element 12 is also equipped with an overheat protection device. The controller is electrically connected to the temperature control element 14. The real-time temperature of the heating wire is transmitted to the temperature control element 14 through the temperature sensor 141. The controller then monitors the temperature control element 14 in real time. When the controller detects that the temperature of the heating wire exceeds the threshold (45°C), the battery unit cuts off the power to the heating element 12 and stops heating.

[0041] To facilitate users in viewing the temperature of the handle body 11 in real time, the temperature control component 14 is also equipped with a screen 142 for users to view the temperature of the handle body 11.

[0042] In the electric handcart, the handle assembly 1 has two handle bodies 11, each of which is equipped with a heating element 12, and the heating elements 12 of the two handles 1 are connected to a temperature control element 14.

[0043] In this way, the temperature of the two handle bodies 11 is regulated by the same control system. Users can set the target temperature through the control system to achieve constant temperature control of the two handle bodies 11.

[0044] The battery compartment 2 is located between the two handle bodies 11 and is fixedly connected to the handle bodies 11 by bolts. Besides the preferred embodiment described above, this utility model has other embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection claimed by this utility model.
