Description

Technical Field

[0001] The invention relates to the field of door knockers, and in particular to a thermoformed laser welded integrated door knocker structure. Background Art

[0002] With the development of the automobile industry, lightweight and high-strength vehicle bodies have become the main design trends. The door ring structure of an automobile plays a vital role in vehicle design. It is not only related to the safety performance of the vehicle, but also directly affects the lightweight and cost control of the vehicle body. The door ring structure effectively enhances the strength and rigidity of the side of the vehicle body by forming a closed-loop frame, and can provide better protection in the event of a side collision.

[0003] When the door knocker is installed, a battery pack will be installed inside to power the electronic components on the surface of the door knocker. However, the existing door knocker structure does not have cooling parts designed for the battery pack. In addition, since the battery pack generates a large amount of heat during operation, if the heat is not dissipated in a timely and effective manner, it may cause battery performance to decline, shorten its life, and even cause safety accidents. How to solve these problems has become an urgent problem to be solved by technical personnel in this field. Summary of the invention

[0004] In order to make up for the above deficiencies, the present invention provides a thermoformed laser welded one-piece door ring structure, which aims to solve the problem that the existing one-piece door ring structure cannot cool the battery pack.

[0005] The present invention is achieved in that: The present invention provides a thermoformed laser welded integrated door ring structure, comprising an integrated door ring body and a battery pack, wherein the battery pack is located on the outer wall of the integrated door ring body, and further comprising: The heat dissipation component 1 is located on the outer wall of the integrated door ring body. The existence of the heat dissipation component 1 can discharge the heat generated by the battery pack during operation, thereby ensuring that the battery pack will not work for a long time in a high temperature environment.

[0006] The heat dissipation component 2 is located on the top of the heat dissipation component 1. The existence of the heat dissipation component 2 can assist the operation of the heat dissipation component 1, thereby further improving the cooling speed of the hot air around the battery pack and improving the protection effect of the battery pack.

[0007] A cooling component is located on the outer wall of the integrated door ring body. The existence of the cooling component can be used in conjunction with heat dissipation component 1 and heat dissipation component 2 when they are unable to quickly lower the temperature of the battery pack, thereby further ensuring the safe operation of the battery pack.

[0008] Preferably, the heat dissipation component includes a heat-conducting shell, a vent, a movable plate, a track, a slider, a spring and a hollow plate, the heat-conducting shell is installed on the inner wall of the integrated door ring body, the vent is opened on the inner wall of the integrated door ring body, the movable plate is installed inside the heat-conducting shell, the track is fixedly connected to the inner wall of the heat-conducting shell, the slider is fixedly connected to the outer wall of the movable plate, the spring is arranged inside the heat-conducting shell, and the hollow plate is fixedly connected to the inside of the heat-conducting shell.

[0010] By adopting the above technical solution, the hot air inside the heat-conducting shell can be discharged through the vents, and the movable plate can slide inside the heat-conducting shell. When the movable plate moves to the bottom of the inside of the heat-conducting shell, the movable plate cannot close the space inside the heat-conducting shell.

[0011] Preferably, the slider is located inside the track, the outer wall of the slider is slidably connected to the inner wall of the track, the bottom of the slider is fixedly connected to the top of the spring, the bottom of the spring is fixedly connected to the outer wall of the integrated door ring body, and the top of the hollow plate abuts against the bottom of the battery pack.

[0012] By adopting the above technical solution, the slider can slide inside the track under the action of the movable plate. When the slider moves, it will exert pressure on the spring. In the absence of external force, the spring will push the slider to reset the movable plate, and the hollow plate can support the battery pack.

[0013] Preferably, the second heat dissipation component includes a heat dissipation pipe, a ventilation pipe, a closing plate, a cylinder and a slide rail, the heat dissipation pipe is fixedly connected to the top of the heat-conducting shell, the ventilation pipe is installed on the outer wall of the heat dissipation pipe, the closing plate is installed inside the heat dissipation pipe, the cylinder is fixedly connected to the outer wall of the closing plate, and the slide rail is opened inside the heat dissipation pipe.

[0014] Preferably, the heat dissipation pipe is connected to the interior of the heat-conducting shell, the end of the air permeable pipe away from the heat dissipation pipe is connected to the outside of the integrated door ring body, and the outer wall of the closing plate is slidably connected to the inner wall of the heat dissipation pipe.

[0015] By adopting the above technical solution, the hot air inside the heat-conducting shell can be discharged through the heat dissipation pipe and the air-permeable pipe, and the closing plate will slide inside the heat dissipation pipe under the action of the high-pressure gas.

[0016] Preferably, the cylinder is located inside the slide rail and is slidably connected to the inner wall of the slide rail.

[0017] By adopting the above technical solution and the arrangement of the cylinder and the slide rail, the stability of the closing plate during its ascent can be ensured without tilting.

[0018] Preferably, the cooling component includes a coolant tank, a delivery pipe, a pump, a flow inner groove and a temperature sensor, the coolant tank is fixedly connected to the outer wall of the integrated door ring body, the delivery pipe is fixedly connected to the outer wall of the coolant tank, the pump is installed at one end of the delivery pipe, the flow inner groove is opened inside the heat-conductive outer shell, and the temperature sensor is fixedly connected to the inner wall of the heat-conductive outer shell.

[0019] Preferably, one end of the delivery pipe away from the coolant tank is connected to the flow inner tank, and the temperature sensor is connected to the pump through a central console signal.

[0020] By adopting the above technical solution, when the temperature sensor detects that the temperature inside the heat-conducting shell is too high, it will control the pump to start, extract the coolant, and transport it to the inside of the flow tank, thereby cooling the heat-conducting shell.

[0021] The beneficial effects of the present invention are: 1. The distinguishing features of the present invention from the prior art are as follows: by arranging air vents and movable plates on the outer wall of the battery pack, the battery pack will heat the internal air of the heat-conducting outer shell when it is in operation, so that the air pressure inside the heat-conducting outer shell increases, and the high-pressure air pushes the movable plate down until it is separated from the heat-conducting outer shell. At this time, the high-pressure air will be discharged through the gap and air vents between the movable plate and the heat-conducting outer shell, thereby solving the problem that the existing integrated door ring structure cannot cool the battery pack; at the same time, when the car is driving, the high-speed flowing air will cause the bottom of the movable plate to be in a negative pressure state, thereby sucking the movable plate downward, and at this time, the hot air inside the heat-conducting outer shell will be drawn out under the action of the negative pressure, thereby achieving the effect of cooling the battery pack.

[0022] 2. The distinguishing feature of the present invention from the prior art is that by arranging a heat dissipation tube and a closing plate on the outer wall of the battery pack, the high-pressure air inside the heat-conducting shell can push the closing plate to slide inside the heat dissipation tube and move to the top of the air vent. At this time, the hot air inside the heat-conducting shell will be discharged through the heat dissipation tube and the air vent, and the auxiliary air vent will cool the battery pack.

[0023] 3. The distinguishing feature of the present invention from the prior art is that a temperature sensor is installed inside the heat-conducting outer shell. When the temperature sensor detects that the temperature inside the heat-conducting outer shell is too high, the pump is started through the main console, so that the pump draws coolant from the inside of the coolant tank and transports it to the inside of the flow tank, thereby cooling the heat-conducting outer shell and further improving the cooling efficiency of the battery pack.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Example 1: Reference Figure 1-Figure 6 A thermoformed laser welded integrated door ring structure comprises an integrated door ring body 1 and a battery pack 3, wherein the battery pack 3 is located on the outer wall of the integrated door ring body 1, and further comprises: The heat dissipation component 2 is located on the outer wall of the integrated door ring body 1. The existence of the heat dissipation component 2 can discharge the heat generated by the battery pack 3 during operation, thereby ensuring that the battery pack 3 will not work for a long time in a high temperature environment.

[0029] The heat dissipation component 2 4 is located on the top of the heat dissipation component 1 2 . The existence of the heat dissipation component 2 4 can assist the operation of the heat dissipation component 1 2 , thereby further improving the cooling speed of the hot air around the battery pack 3 and improving the protection effect of the battery pack 3 .

[0030] The cooling component 5 is located on the outer wall of the integrated door ring body 1. The cooling component 5 can be used in conjunction with the heat dissipation component 1 2 and the heat dissipation component 2 4 when they are unable to quickly lower the temperature of the battery pack 3, thereby further ensuring the safe operation of the battery pack 3.

[0031] The heat dissipation component 2 includes a heat-conducting shell 201, a vent 202, a movable plate 203, a track 204, a slider 205, a spring 206 and a hollow plate 207. The heat-conducting shell 201 is installed on the inner wall of the integrated door knocker body 1, the vent 202 is opened on the inner wall of the integrated door knocker body 1, the movable plate 203 is installed inside the heat-conducting shell 201, the track 204 is fixedly connected to the inner wall of the heat-conducting shell 201, the slider 205 is fixedly connected to the outer wall of the movable plate 203, the spring 206 is arranged inside the heat-conducting shell 201, and the hollow plate 207 is fixedly connected to the inside of the heat-conducting shell 201.

[0032] It should be noted that: the vent hole 202 is connected to the interior of the heat-conducting shell 201, and the hot air inside the heat-conducting shell 201 can be discharged through the vent hole 202. The outer wall of the movable plate 203 is slidably connected to the inner wall of the heat-conducting shell 201, and the movable plate 203 can slide inside the heat-conducting shell 201. When the movable plate 203 moves to the bottom of the interior of the heat-conducting shell 201, the movable plate 203 cannot close the space inside the heat-conducting shell 201. The size of the internal bottom space of the heat-conducting shell 201 is larger than the size of the heat-conducting shell 201. The slider 205 is located inside the track 204. The slider 205 5 is slidably connected to the inner wall of the track 204. The slider 205 can slide inside the track 204 under the action of the movable plate 203. The bottom of the slider 205 is fixedly connected to the top of the spring 206. The bottom of the spring 206 is fixedly connected to the outer wall of the integrated door knocker body 1. When the slider 205 moves, it will exert pressure on the spring 206. In the absence of external force, the spring 206 will push the slider 205, thereby resetting the movable plate 203. The top of the hollow plate 207 abuts against the bottom of the battery pack 3, and the hollow plate 207 can support the battery pack 3.

[0033] By arranging air vents 202 and movable plates 203 on the outer wall of the battery pack 3, the battery pack 3 will heat the internal air of the heat-conducting outer shell 201 when it is in operation, so that the air pressure inside the heat-conducting outer shell 201 increases, and the high-pressure air pushes the movable plate 203 down until it is separated from the heat-conducting outer shell 201. At this time, the high-pressure air will be discharged through the gap between the movable plate 203 and the heat-conducting outer shell 201 and the air vents 202, thereby solving the problem that the existing integrated door ring structure cannot cool the battery pack 3; at the same time, when the car is driving, the high-speed flowing air will make the bottom of the movable plate 203 in a negative pressure state, thereby sucking the movable plate 203 downward, and at this time, the hot air inside the heat-conducting outer shell 201 will be drawn out under the action of the negative pressure, thereby achieving the effect of cooling the battery pack 3.

[0034] When the battery pack 3 is in operation, it will heat the internal air of the heat-conductive shell 201, so that the air inside the heat-conductive shell 201 starts to heat up. At this time, the high-temperature air will cause the internal air pressure of the heat-conductive shell 201 to increase, and the high-pressure air will apply a thrust to the movable plate 203 through the hollow plate 207, so that the movable plate 203 drives the slider 205 to descend. When the slider 205 descends, it applies pressure to the spring 206. When the movable plate 203 separates from the heat-conductive shell 201 during the descent process, the high-temperature and high-pressure air inside the heat-conductive shell 201 will flow to the bottom of the movable plate 203 through the gap between the heat-conductive shell 201 and the movable plate 203, and be discharged through the vent 202, thereby having a cooling effect on the interior of the heat-conductive shell 201.

[0035] The heat dissipation component 24 includes a heat dissipation pipe 401, a ventilation pipe 402, a closing plate 403, a cylinder 404 and a slide rail 405. The heat dissipation pipe 401 is fixedly connected to the top of the heat-conducting housing 201, the ventilation pipe 402 is installed on the outer wall of the heat dissipation pipe 401, the closing plate 403 is installed inside the heat dissipation pipe 401, the cylinder 404 is fixedly connected to the outer wall of the closing plate 403, and the slide rail 405 is opened inside the heat dissipation pipe 401.

[0036] It should be noted that: the heat dissipation pipe 401 is connected to the interior of the heat-conducting shell 201, and the end of the air pipe 402 away from the heat dissipation pipe 401 is connected to the outside of the integrated door ring body 1. The hot air inside the heat-conducting shell 201 can be discharged through the heat dissipation pipe 401 and the air pipe 402. The outer wall of the closing plate 403 is slidingly connected to the inner wall of the heat dissipation pipe 401. Under the action of the high-pressure gas, the closing plate 403 will slide inside the heat dissipation pipe 401. The cylinder 404 is located inside the slide rail 405 and is slidingly connected to the inner wall of the slide rail 405. The setting of the cylinder 404 and the slide rail 405 can ensure the stability of the closing plate 403 during the rising process and will not tilt.

[0037] By arranging a heat dissipation tube 401 and a closing plate 403 on the outer wall of the battery pack 3, the high-pressure air inside the heat-conducting shell 201 can push the closing plate 403 to slide inside the heat dissipation tube 401 and move to the top of the air vent 402. At this time, the hot air inside the heat-conducting shell 201 will be discharged through the heat dissipation tube 401 and the air vent 402, and the auxiliary air vent 202 will cool down the battery pack 3.

[0038] When the battery pack 3 is in operation, the air inside the heat-conducting housing 201 is heated. When the air is heated, the air pressure increases. At this time, the high-pressure air will push the closing plate 403 to slide inside the heat dissipation tube 401. When the closing plate 403 moves to the top of the ventilation tube 402, the high-pressure air will be discharged through the heat dissipation tube 401 and the ventilation tube 402.

[0039] Example 2: Please refer to Example 1 for details. Figure 1-Figure 2 and Figure 7-Figure 8 The cooling component 5 includes a cooling liquid tank 501, a delivery pipe 502, a pump 503, a flow inner groove 504 and a temperature sensor 505. The cooling liquid tank 501 is fixedly connected to the outer wall of the integrated door ring body 1, the delivery pipe 502 is fixedly connected to the outer wall of the cooling liquid tank 501, the pump 503 is installed at one end of the delivery pipe 502, the flow inner groove 504 is opened inside the heat-conducting outer shell 201, and the temperature sensor 505 is fixedly connected to the inner wall of the heat-conducting outer shell 201.

[0040] It should be noted that: the end of the delivery pipe 502 away from the coolant tank 501 is connected to the flow inner tank 504, and the temperature sensor 505 is connected to the pump 503 through the central console signal. When the temperature sensor 505 detects that the temperature inside the heat-conducting outer shell 201 is too high, it will control the pump 503 to start, extract the coolant, and deliver it to the inside of the flow inner tank 504, thereby cooling the heat-conducting outer shell 201.

[0041] By installing a temperature sensor 505 inside the heat-conducting outer shell 201, when the temperature sensor 505 detects that the temperature inside the heat-conducting outer shell 201 is too high, the operation of the pump 503 will be started through the main console, so that the pump 503 draws the coolant from the inside of the coolant tank 501 and transports it to the inside of the flow inner tank 504, thereby cooling the heat-conducting outer shell 201 and further improving the cooling efficiency of the battery pack 3.

For those skilled in the art, the present invention may have various modifications and variations.
