Description

Technical Field

[0001] The present invention relates to the technical field of heaters, in particular to an invisible heater for a windshield. Background Art

[0002] Windshields are a type of safety glass widely used in the side, front, and rear windows of modern vehicles. Compared to laminated glass, windshields increase their strength through heat and pressure. When damaged, they shatter into small, smooth particles resembling breadcrumbs, reducing the risk of injury from glass fragments. However, fluctuations in air temperature and temperature differences between inside and outside the vehicle can cause changes in the internal and external surface temperatures, which can easily lead to fogging of the windshield's interior and exterior surfaces. This can affect the driver's vision and disrupt the vehicle's normal operation. Therefore, a windshield heater is required to regulate the surface temperature and prevent fogging.

[0003] However, existing heaters for windshields have a single functional design and cannot provide effective protection for the heater. The heater is easily hit by foreign objects and easily comes into contact with water, which affects the normal use of the heater. In addition, the heater has a low heat transfer rate and low heating efficiency for the windshield. Therefore, corresponding improvements are needed to address the above points. Summary of the Invention

[0004] The object of the present invention is to provide an invisible heater for a windshield to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solutions: an invisible heater for a windshield, comprising a wiper, a waterproof plate installed at the bottom end of the interior of the wiper, and a plurality of groups of heat transfer holes are opened in the interior of the waterproof plate, and a heat transfer film is provided inside the plurality of heat transfer holes, a connector is installed on the inner wall of the corresponding side of the wiper, and a mounting groove is opened on the corresponding side of the connector, a plurality of groups of limiting balls are provided on the side wall of the mounting groove, and a connecting column is installed at the middle position of the inner wall of one end of the mounting groove, a cable is installed on the corresponding other side of the connector, a plurality of groups of threaded grooves are opened on the inner walls of both sides of the wiper near the bottom end, and scraping strips are installed on both sides of the bottom end of the wiper, a motor is installed on the inner wall of the corresponding other side of the wiper, and the output end of the motor is connected to the rotating shaft in a transmission manner, a mounting disk is installed at one end of the rotating shaft, and a heating rod is installed on the corresponding side of the mounting disk, and the plug interface and the connecting column are movably plugged in. The top of each of the plurality of limit blocks is fixed with a plurality of support rods, and the top of each of the plurality of mounting rods is fixed with the top inner wall of the wiper blade. Support rods are installed on the corresponding two sides of the plurality of limit blocks, and one end of each of the plurality of support rods is fixed with the inner wall of the corresponding side of the wiper blade. Heat-conducting rods are installed on both sides of the bottom end of the internal part of the limit block, and the bottom ends of the corresponding two groups of heat-conducting rods are respectively fixed with the corresponding positions of the top ends of the corresponding heat-conducting plates. The corresponding ends of the heat-conducting rods are fitted with the outer surfaces of the heating rods, and fixing plates are installed on the corresponding two sides of the heat-conducting plates near the two ends, and the corresponding fixing plates are movably screwed with fixing bolts, and the corresponding ends of the fixing bolts are movably screwed with the corresponding threaded grooves.

[0006] Preferably, one end of the heating rod extends into the installation groove.

[0007] Preferably, the sizes of the plurality of groups of limiting balls are equal, and the outer surfaces of the plurality of groups of limiting balls are all arranged to fit the outer surface of one end of the heating rod.

[0008] Preferably, the corresponding heat conducting rods are of equal size, and corresponding ends of the corresponding heat conducting rods respectively pass through the interior of the corresponding limiting blocks and extend to the interior of the corresponding through holes.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] The setting of components such as wipers, waterproof plates, heat transfer holes, and heat transfer films can effectively solve the problem of single functional design, inability to effectively protect the heater, and the heater being easily hit by foreign objects and easily coming into contact with water, thereby affecting the normal use of the heater.

[0011] The problem of low heating transfer rate of the heater and low heating efficiency of the windshield can be effectively solved by setting up components such as a motor, a rotating shaft, a mounting plate, a heat conducting rod and a heat conducting plate.

[0012] While the heating rod rotates, several corresponding groups of support balls arranged inside the corresponding limit blocks can limit the heating rod, and several corresponding groups of limit balls limit the corresponding end of the heating rod, so that the heating rod is more stable and less likely to shake when rotating.

[0013] The corresponding limit block is installed in the interior of the wiper by the corresponding mounting rod and the corresponding two sets of support rods, and one end of the heating rod passes through the corresponding through hole to pass through the interior of the corresponding limit block.

Several groups of limiting balls 17 are provided on the side wall of the mounting groove 16, and a connecting column 18 is installed at the middle position of the inner wall of one end of the mounting groove 16. The sizes of the several groups of limiting balls 17 are equal, and the outer surfaces of the several groups of limiting balls 17 are all fitted with the outer surface of one end of the heating rod 23. A cable 19 is installed on the other side of the connector 15. One end of the cable 19 is electrically connected to the controller inside the car, and the controller is controlled by the corresponding control system in the car.

[0023] A motor 2 is installed on the inner wall of the other side of the wiper 1, and the output end of the motor 2 is transmission-connected to a rotating shaft 21. A mounting disk 22 is installed at one end of the rotating shaft 21, and a heating rod 23 is installed on the corresponding side of the mounting disk 22. One end of the heating rod 23 passes through the corresponding through hole 31 and penetrates the interior of the corresponding limit block 3. An insertion port 24 is installed inside one end of the heating rod 23 through a bearing. One end of the heating rod 23 extends into the interior of the mounting groove 16, and the insertion port 24 and the connecting column 18 are movably plugged in.

[0024] The outer surface of the heating rod 23 is sleeved with several groups of limit blocks 3, and the interiors of the several groups of limit blocks 3 are provided with through holes 31, and the inner walls of the through holes 31 are provided with several groups of support balls 32. The outer surfaces of the several groups of support balls 32 are all fitted with the outer surface of the heating rod 23. The interior of the limit block 3 is provided with heat-conducting rods 35 on both sides of the bottom end, and the bottom ends of the corresponding two groups of heat-conducting rods 35 are respectively fixed to the corresponding positions of the top ends of the corresponding heat-conducting plates 36. The corresponding heat-conducting rods 35 are equal in size, and the corresponding ends of the corresponding heat-conducting rods 35 respectively pass through the interior of the corresponding limit block 3 and extend to the interior of the corresponding through hole 31. The heat-conducting rods 35 are 5 are fitted with the outer surface of the heating rod 23, and the corresponding ends of the heat conducting plate 36 are installed with fixing plates 37 at the positions near the two ends on both sides, and the interiors of the corresponding fixing plates 37 are movably screwed with fixing bolts 38, and the corresponding ends of the corresponding fixing bolts 38 are movably screwed with the corresponding threaded grooves 10, and the tops of several groups of limit blocks 3 are installed with mounting rods 33, and the tops of several groups of mounting rods 33 are fixed to the inner walls of the tops of the wiper 1, and the corresponding two sides of several groups of limit blocks 3 are installed with support rods 34, and one ends of the corresponding groups of support rods 34 are fixed to the inner walls of the corresponding sides of the wiper 1.

[0025] During use, when the windshield needs to be heated, the user can use the cable 19, connector 15, connecting column 18 and plug interface 24 to enable the heating rod 23 to perform corresponding heating treatment, so that the heat can fill the interior of the wiper 1, so that the air inside the wiper 1 becomes hot, and then the hot air can be transferred to the surface of the windshield through several groups of heat transfer holes 13 and several groups of heat transfer films 14, thereby heating it accordingly. At the same time, one end of the corresponding heat-conducting rod 35 will be in contact with the outer surface of the heating rod 23, so that the heat generated by the heating rod 23 can be transferred to the outer surface of the corresponding heat-conducting plate 36 through the corresponding heat-conducting rod 35, and then the corresponding heat-conducting plate 36 can perform corresponding heating treatment, and the heat can be transferred to the surface of the windshield through several groups of heat transfer holes 13 and several groups of heat transfer films 14, thereby further improving the heating efficiency of the windshield.

[0026] While heating, the user can start the motor 2. Under the action of the motor 2, the rotating shaft 21 and the mounting plate 22 can rotate accordingly, thereby causing the corresponding heating rod 23 to rotate. Under the action of the rotation of the heating rod 23, the air circulation rate inside the wiper 1 can be accelerated, thereby allowing the hot air inside the wiper 1 to be more quickly transferred to the windshield surface through several groups of heat transfer holes 13 and several groups of heat transfer films 14, thereby further improving the heating efficiency of the windshield. While the heating rod 23 rotates, the corresponding several groups of support balls 32 arranged inside the corresponding limit block 3 can limit the heating rod 23, and the corresponding several groups of limit balls 17 limit the corresponding one end of the heating rod 23, thereby making the heating rod 23 more stable and less likely to shake when rotating. Since a plug-in interface 24 is installed inside one end of the heating rod 23 through a bearing, and the plug-in interface 24 is plugged into the connecting column 18, the plug-in interface 24 and the connecting column 18 will not rotate with the rotation of the heating rod 23.

[0027] The corresponding limit block 3 is installed in the interior of the wiper 1 by the corresponding mounting rod 33 and the corresponding two sets of support rods 34, and one end of the heating rod 23 passes through the interior of the corresponding limit block 3 through the corresponding through hole 31, so the corresponding limit block 3 can play a limiting and supporting role for the heating rod 23, so that the entire heating rod 23 is always set at the same horizontal height, thereby facilitating the normal use of the heating rod 23.

[0028] Since the heating rod 23 is arranged inside the wiper 1, and a waterproof plate 12, several groups of heat transfer holes 13 and several groups of heat transfer films 14 are installed near the bottom of the wiper 1, it is not only possible to make the heating rod 23 invisible, but also to solve the problem that the existing heaters for windshields have a single functional design and cannot effectively protect the heating rod 23. The heating rod 23 is easily hit by foreign objects and easily comes into contact with water, thereby affecting the normal use of the heating rod 23.

[0029] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
