Description

A PTC constant temperature heating electric bicycle windshield

Technical field

The utility model relates to a windproof and warm warming article, in particular to an electric bicycle windshield with a constant temperature heating function. It belongs to the field of daily necessities.

Background technique

Today, electric bicycles are an important means of transportation for people to travel, and there are many users of electric bicycles. When riding in the winter, the body is particularly uncomfortable when exposed to the outside.

People often install windshields on electric bicycles during the winter. However, the windshield used by people can only provide basic wind protection, and the hem of the windshield is not closed, and is floating when riding, and the warmth effect is not ideal. The existing windshield with heating function is used as a heating material for the windshield, but the temperature of the heating wire is uncontrollable, and it is easy to burn the lining and the outer windproof layer. Moreover, the electric bicycle battery is used to supply power to the heating layer, and the circuit needs to be modified, and the process is complicated.

Patent CN205098357U discloses an electric bicycle windshield with heating function, which uses a special battery to supply power to the resistance wire, but the temperature of the resistance wire is uncontrollable, and the battery is installed in the vest, the structure is complicated, and the disassembly and charging is difficult. At the same time, its hem has no design to close the hem, and the design can be improved.

Utility model content

The purpose of the utility model is to provide a PTC constant temperature heating electric bicycle windshield, which solves the problem that the existing windshield is not heated by using a heating device or a temperature uncontrollable electric resistance wire, and the need to use the battery power supply There are problems with the line to be transformed. The utility model simultaneously adopts a hem which can be combined to increase the warming effect.

The main technical scheme adopted by the PTC constant temperature heating electric bicycle windshield according to the utility model is:

The PTC thermostatically heated electric bicycle windshield includes an upper windshield, a protective sleeve, a side windshield, a front windshield, a permanent magnet and a pocket. The upper windshield, the protective sleeve, the side windshield, and the front windshield are sewn together. The permanent magnet is sewn to the hem by a side cover windshield. The pocket is sewn to the inside of the front windshield. The windshield is a waterproof windproof layer, a heat insulating layer, a PTC constant temperature heating layer and a lining from the outside to the inside, and the heat insulating layer is made of a flexible material which can be folded and folded multiple times to prevent heat. The PTC heating layer is soft in texture, and the positive and negative wires are taken out from the heating layer and supplied by the mobile power source. The protective sleeve has an opening, and the two protective sleeves are respectively passed through the left and right handlebars during installation, and then fastened with a cloth strip or the like to install the windshield on the electric vehicle. The permanent magnets put together the hem of the side windshield before riding, which can increase the warmth effect of the windshield. When the vehicle is pulled out, the legs can be opened with a little force, and the vehicle is not affected at all. The pocket is sewn on the lining for placing a mobile power source or other item.

The positive electrode and the negative electrode of the wire are connected by a PTC polymer material. When the wire is energized according to the requirements of the positive and negative electrodes, because the initial temperature is low, the resistance of the PTC polymer material is small, the internal current is large, and the heat is rapid, so that the wind is quickly heated. When the temperature reaches the design temperature, that is, the Curie temperature of the PTC material, the resistance of the PTC polymer material rapidly increases, and the heat generation of the heat generating layer is reduced, so that the wind shield can be kept constant.

Compared with the prior art, the utility model has the following advantages

1. PTC polymer material is used as the heating layer, and the wind is heated quickly to improve the warmth of the bicycle.

2. Make full use of the self-constant temperature characteristics of PTC polymer materials, and do not need to control the temperature while the windshield heating function is realized, so that the riding is safer and more comfortable.

3. PTC heating external mobile power supply, no need to modify the electric vehicle line, more convenient to use.

4. The side windshield is provided with permanent magnets at the hem, and the hem can be combined to increase the warmth effect before riding, and does not affect the rider to get off.

detailed description

The present invention is further described in the following with reference to the accompanying drawings and specific embodiments. It is understood that the following embodiments are only used in the present invention and are not intended to limit the scope of the invention.

Figure 1 shows a PTC thermostatically heated electric bicycle windshield by an external view, from top to bottom, the upper windshield 1, the protective sleeve 2, the side windshield 3, the front windshield 4, waterproof and windproof The layer 5, the heat insulating layer 6, the PTC constant temperature heating layer 7, the lining 8, and the permanent magnet 9. The windshield of each part is connected by sewing. The permanent magnet 9 is sewn to the hem by a side cover windshield. The protective sleeve 2 has a relatively open opening. When installing, the two protective sleeves are respectively passed through the left and right handlebars, and then tied with a cloth strip or the like to install the windshield on the electric vehicle. The upper windshield 1, the protective sleeve 2, the side windshield 3, and the front windshield 4 are sandwiched between the heat insulating layer and the PTC heating layer. The windshield is a waterproof windproof layer 5, a heat insulating layer 6, a PTC constant temperature heating layer 7, and a lining 8 from the outside to the inside. The heat insulating layer 6 is made of a flexible material which can be folded and folded multiple times to prevent heat leakage; the PTC constant temperature heating layer 7 is soft in texture, and two positive and negative wires are taken out from the heating layer and supplied by a mobile power source. The permanent magnets 9 are respectively sewn on the two sides of the side windshield 4 hem, and the hem is put together before riding, which can increase the warmth effect, and the hem can be opened with a slight force on both legs when getting off the vehicle, without affecting at all. get off.

A PTC thermostatically heated electric bicycle windshield shown in Fig. 2 is shown in an internal view, except for the portion shown in Fig. 1, which is a cuff 10, a wire 11 and a pocket 12 from top to bottom. The cuff 10 is used to pass the handle of the rider through the handlebar. The wire 11 is taken out by the PTC constant temperature heating layer to obtain power from the mobile power source. The pocket 12 is sewn to the liner for placement of a mobile power source or other item.

The positive electrode and the negative electrode of the wire 11 are connected by a PTC polymer material. When the wire 11 is energized according to the requirements of the positive and negative electrodes, since the initial temperature is low, the resistance of the PTC polymer material is small, the internal current is large, and the heat is rapid, so that the wind is rapidly heated. When the temperature reaches the design temperature, that is, the Curie temperature of the PTC material, the resistance of the PTC polymer material rapidly increases, and the heat generation of the heat generating layer is reduced, so that the wind shield can be kept constant.

The advantages of the utility model are:
