Description

Technical Field

[0001] This utility model relates to the field of cabin door technology, and in particular to an automobile cabin door closing device and a vehicle. Background Technology

[0002] The hatch is an indispensable part of a car. Every car, especially a tour bus, has storage space inside the vehicle in order to store luggage and other items. The hatch is a necessary component for sealing the storage space.

[0003] The hatch is usually a manually operated opening and closing mechanism. When the user turns the hatch to close it, they usually apply a force to the hatch once. Under this force, the hatch turns until it locks with the vehicle body. However, due to the difference in the amount of force applied, when the force is small, the user needs to apply a second force to lock it. When the force is large, the operation is laborious and will reduce the service life of the hatch. In addition, the loud noise when closing the hatch, or the need to press a second time to ensure that the hatch is locked, all contribute to the laborious operation and affect the user's comfort.

[0023] The hatch is an indispensable part of a car. Every car, especially a tour bus, has storage space inside the vehicle in order to store luggage and other items. The hatch is a necessary component for sealing the storage space.

[0024] The hatch is usually a manually operated opening and closing mechanism. When the user turns the hatch to close it, they usually apply a force to the hatch once. Under this force, the hatch turns until it locks with the vehicle body. However, due to the difference in the amount of force applied, when the force is small, the user needs to apply a second force to lock it. When the force is large, the operation is laborious and will reduce the service life of the hatch. In addition, the loud noise when closing the hatch, or the need to press a second time to ensure that the hatch is locked, all contribute to the laborious operation and affect the user's comfort.

[0025] This utility model proposes a car door closing device.

[0026] Please see Figure 1 In one embodiment of this utility model, the car door closing device includes: Cabin frame 20; The hatch 30 is rotatably mounted on the hatch frame 20 and can be fastened to the hatch frame 20; The control unit is located on the frame 20 and / or the door 30. The control unit is configured to detect the position information between the door 30 and the frame 20 when the door is closed, and generate an adsorption command when the position information reaches a preset threshold. An adsorption assembly is provided on the frame 20 and / or the door 30. The adsorption assembly is configured to generate a magnetic attraction force in response to the adsorption command of the control unit, so that the frame 20 and the door 30 are tightly attached and fastened together.

[0027] like Figure 1 As shown, the car is equipped with a storage cavity for storing objects, the frame 20 is located at the opening of the storage cavity, and the door 30 is rotatably connected to the frame 20.

[0028] It is understandable that the opening or closing of the receiving cavity is achieved when the hatch 30 rotates to approach or move away from the hatch frame 20.

[0029] In order for the adsorption unit to respond to the adsorption command generated by the control unit, the adsorption unit is connected to the control unit via a signal connection.

[0030] Understandably, the adsorption command generated by the control unit can be transmitted to the adsorption group via a signal. The adsorption group responds to the adsorption command and generates magnetic attraction to make the frame 20 and the door 30 fit tightly together and fasten.

[0031] In one embodiment, the adsorption group is disposed on the frame 20. When the adsorption group responds to the adsorption command and generates magnetic attraction, the door 30 rotates and approaches the frame 20. The adsorption group then attracts the door 30 so that the door 30 is tightly attached to the frame 20, thereby facilitating the door 30 to be fastened to the frame 20.

[0032] In another embodiment, the adsorption group is disposed on the door 30. When the adsorption group responds to the adsorption command and generates magnetic attraction, the door 30 rotates and approaches the frame 20. The adsorption group attracts the frame 20, and the door 30 continues to rotate and approach the frame 20 under the action of magnetic attraction, thereby assisting the door 30 to rotate and closely adhere to the frame 20, so as to facilitate the door 30 to be fastened to the frame 20.

[0033] It should be noted that the adsorption group is set on the cabin frame 20 or the cabin door 30, and when the adsorption group generates magnetic attraction, the cabin frame 20 or the cabin door 30 is made of magnetic material. Only in this way can the magnetic attraction generated by the adsorption group make the cabin door 30 rotate and continue to approach and stick tightly to the cabin frame 20.

[0034] In another embodiment, the adsorption group is partially disposed on the frame 20 and the adsorption group is partially disposed on the door 30.

[0035] The adsorption assembly on the frame 20 is positioned opposite to the adsorption assembly on the door 30.

[0036] It is understandable that when the adsorption group generates magnetic attraction, the adsorption group on the hatch 30 attracts the adsorption group on the door frame 20, which causes the hatch 30 to rotate and stick tightly to the door frame 20. At this time, the materials of the hatch 30 and the door frame 20 are not restricted.

[0037] In another embodiment, the adsorption group is partially disposed on the chamber frame 20 and partially disposed on the chamber door 30, and the adsorption group disposed on the chamber frame 20 and the adsorption group disposed on the chamber door 30 are attracted to each other.

[0038] like Figure 3 As shown, the control unit is used to detect the position information between the hatch 30 and the hatch frame 20 when the hatch 30 rotates and approaches the hatch frame 20, and to determine the size between the position information and a preset threshold. When the position information reaches the preset threshold, the control unit generates an adsorption command.

[0039] It should be noted that during the process of manually closing the hatch 30, the hatch 30 rotates closer to the hatch frame 20. If the user rotates the hatch 30 with too much force, although the hatch 30 can be locked onto the hatch frame 20, it will make a lot of noise when closing. If the user rotates the hatch 30 with too little force, although the hatch 30 will be closer to the hatch frame 20 after rotation, the hatch 30 will not be able to fit snugly against the hatch frame 20 and thus be easy to lock.

[0040] Therefore, during the process of the user turning and closing the hatch 30, the control unit detects the position information between the hatch 30 and the hatch frame 20. When the position information reaches a preset threshold, it means that the hatch 30 is close to the hatch frame 20. At this time, if the magnetic attraction force generated by the adsorption group can drive the hatch 30 to rotate and fit against the hatch frame 20 during the magnetic attraction process, the control unit generates an adsorption command.

[0041] It should be noted that the preset threshold is set in advance. The size of the preset threshold is set according to the magnitude of the magnetic attraction force generated by the adsorption group, so as to ensure that when the adsorption group generates magnetic attraction force, the hatch 30 can rotate and fit with the hatch frame 20 due to the magnetic attraction force.

[0042] Moreover, the position information can be the angle information between the hatch 30 and the frame 20, or the distance information between the hatch 30 and the frame 20.

[0043] In one embodiment, the location information is distance information, and the preset threshold ranges from 4.5 mm to 5.5 mm.

[0044] Preferably, the preset threshold is 5mm. When the position information between the hatch 30 and the frame 20 is 5mm after the hatch 30 rotates, the control unit generates an adsorption command, and the adsorption group responds to the adsorption command. The adsorption group generates a magnetic attraction force, causing the hatch 30 to continue to rotate and approach the frame 20.

[0045] In one embodiment, the position information is angle information.

[0046] Understandably, when the hatch 30 rotates to the preset threshold angle, the control unit generates an adsorption command, and the adsorption group responds to the adsorption command. The adsorption group generates a magnetic attraction force, causing the hatch 30 to continue rotating and approaching the hatch frame 20.

[0047] To facilitate the transmission of adsorption commands to the adsorption unit, the control unit and the adsorption unit are connected by a signal.

[0048] It is understandable that the adsorption command generated by the control unit is transmitted to the adsorption group so that the adsorption group can respond to the adsorption command and generate magnetic attraction.

[0049] In one embodiment, the control unit is disposed on the frame 20, or the control unit is disposed on the door 30.

[0050] In another embodiment, a control section is disposed on the frame 20 and a control section is disposed on the door 30, and the control section disposed on the frame 20 and the control section disposed on the door 30 are connected by a signal.

[0051] The technical solution of this utility model involves setting an adsorption group on the cabin frame 20 and / or cabin door 30. When the cabin door 30 rotates and approaches the cabin frame 20, and the distance between the cabin door 30 and the cabin frame 20 reaches a preset threshold, the control unit generates an adsorption command, and the adsorption group responds to the adsorption command and works to generate magnetic attraction, so that the cabin frame 20 and the cabin door 30 fit together, thereby facilitating the cabin door 30 to fasten to the cabin frame 20. The adsorption group plays an auxiliary closing role when the cabin door 30 is closed, ensuring that the cabin door 30 is stably fastened to the cabin frame 20, improving the convenience of closing the cabin door 30, reducing the noise when the user closes the cabin door 30, and eliminating the user's secondary closing process, greatly improving the user's comfort.

[0052] In one embodiment, the adsorption assembly includes: Power supply unit 40 is provided on the frame 20 and / or the door 30. Power supply unit 40 is electrically connected to adsorption unit 60 and signal connected to control unit. Power supply unit 40 is configured to supply power to adsorption unit 60 when it responds to adsorption command. Adsorption part 60 is provided on the frame 20 and / or the door 30. The adsorption part 60 is configured such that the adsorption part 60 is powered by the power supply part 40 to generate magnetic attraction force so that the frame 20 and the door 30 are tightly attached and fastened.

[0053] like Figure 3 As shown, the power supply unit 40 supplies power to the adsorption unit 60. When the power supply unit 40 supplies power to the adsorption unit 60, the adsorption unit 60 generates magnetic attraction force, so as to drive the hatch 30 to rotate and approach the hatch frame 20.

[0054] It is understandable that when the adsorption unit 60 needs to generate magnetic attraction to make the hatch 30 continue to rotate and approach the hatch frame 20, it is because the control unit detects that the position information between the hatch 30 and the hatch frame 20 has reached a preset threshold, and the control unit generates an adsorption command.

[0055] Therefore, the power supply unit 40 responds to the adsorption command and supplies power to the adsorption unit 60, which then generates a magnetic attraction force to make the hatch 30 continue to rotate under the action of the magnetic attraction force and move closer to the hatch frame 20 until the hatch 30 and the hatch frame 20 are attached to each other and locked together.

[0056] In one embodiment, the power supply unit 40 is a structural component for power supply, and the power supply unit 40 can be a battery or the like.

[0057] In one embodiment, the adsorption part 60 is an electromagnet. When the power supply part 40 supplies power to the adsorption part 60, the electromagnet is energized and generates a magnetic attraction force. Under the action of the magnetic attraction force, the hatch 30 rotates and approaches the hatch frame 20.

[0058] When the adsorption part 60 is installed on the hatch 30, the adsorption part 60 generates a magnetic attraction force due to the power supply part 40. The adsorption part 60 attracts the hatch frame 20, so that the hatch 30 can continue to rotate toward the hatch frame 20 until the hatch 30 and the hatch frame 20 are attached and fastened together.

[0059] When the adsorption part 60 is installed on the cabin frame, when the cabin door 30 rotates and approaches the cabin frame 20, the adsorption part 60 generates a magnetic attraction force and attracts the cabin door 30. Under the action of the magnetic attraction force, the cabin door 30 continues to rotate toward the cabin frame 20 until the cabin door 30 and the cabin frame 20 are attached and locked together.

[0060] When both the frame 20 and the door 30 are provided with adsorption parts 60, if the adsorption parts 60 on the frame 20 and the adsorption parts 60 on the door 30 are arranged opposite to each other, when the door 30 rotates and approaches the frame 20, the adsorption parts 60 generate magnetic attraction, and the two adsorption parts 60 arranged opposite to each other attract each other, causing the door 30 to continue to rotate toward the frame 20 until the door 30 and the frame 20 are attached and fastened together. When the hatch frame 20 and the hatch door 30 are in contact, the adsorption part 60 on the hatch frame 20 and the adsorption part 60 on the hatch door 30 are spaced apart on the hatch frame 20. When the hatch door 30 rotates and approaches the hatch frame 20, the adsorption part 60 generates a magnetic attraction force. The adsorption part 60 on the hatch frame 20 attracts the hatch door 30, and the adsorption part 60 on the hatch door 30 attracts the hatch frame 20, causing the hatch door 30 to continue to rotate toward the hatch frame 20 until the hatch door 30 and the hatch frame 20 are in contact and fastened together.

[0061] When the adsorption unit 60 is installed on the frame 20, the power supply unit 40 is also installed on the frame 20, so that the power supply unit 40 can directly supply power to the adsorption unit 60. Alternatively, the power supply unit 40 can be installed on the door 30, and the power supply unit 40 and the adsorption unit 60 can be connected by a wire. With proper wiring, the power supply unit 40 can supply power to the adsorption unit 60 without affecting the rotation of the door 30.

[0062] When the adsorption unit 60 is installed on the hatch 30, the power supply unit 40 is also installed on the hatch 30, so that the power supply unit 40 directly supplies power to the adsorption unit 60. Alternatively, the power supply unit 40 can be installed on the hatch frame 20. The power supply unit 40 and the adsorption unit 60 are connected by a wire. Through reasonable wiring, the power supply unit 40 supplies power to the adsorption unit 60 without affecting the rotation of the hatch 30.

[0063] When both the frame 20 and the door 30 are equipped with adsorption units 60, both the frame 20 and the door 30 are equipped with power supply units 40, so as to facilitate direct power supply to each adsorption unit 60.

[0064] In one embodiment, the power supply unit 40 includes a power source and a control switch electrically connected to the power source, the control switch being signal-connected to the control unit.

[0065] It should be noted that, in order to facilitate the rotation of the auxiliary hatch 30 and its engagement with the hatch frame 20 when the hatch is closed, an adsorption part 60 is provided on the hatch frame 20 and / or the hatch 30. Under the power supply of the power supply part 40, the adsorption part 60 generates a magnetic attraction force. Under the action of the magnetic attraction force, the hatch 30 rotates and engages with the hatch frame 20. However, when it is necessary to open the hatch, the magnetic attraction force of the adsorption part 60 may easily create resistance to the rotation of the hatch 30, making it inconvenient to open the hatch 30.

[0066] For this purpose, the power supply is electrically connected to the adsorption unit 60, and the power supply is also connected to the control switch signal.

[0067] Understandably, the control switch can control whether the power supply is supplied to the adsorption section 60.

[0068] When the hatch 30 is closed, the control switch will not control the power supply of the power supply unit 40. At this time, the power supply unit 40 supplies power to the adsorption unit 60 in response to the adsorption command of the control unit.

[0069] During the closing process of the hatch 30 and the frame 20, the user can control the power supply unit 40 to continuously supply power to the adsorption unit 60, so that under the action of magnetic attraction, the hatch 30 and the frame 20 will always be in contact to ensure the sealing performance of the hatch 30 when closed.

[0070] like Figure 4 As shown, when the hatch 30 needs to be opened, the user can control the control switch so that the power supply no longer supplies power to the adsorption unit 60. Even if the position information between the hatch 30 and the frame 20 reaches a preset threshold during the opening process of the hatch 30, causing the control unit to generate an adsorption command, the power supply will not respond to the adsorption command because the user controls the control switch, thereby avoiding the resistance to the opening of the hatch 30 due to the magnetic attraction generated by the adsorption unit 60.

[0071] In another embodiment, when the hatch 30 is rotated open, the control unit no longer detects the position information between the hatch 30 and the frame 20, thereby preventing the control unit from generating an adsorption command, thus preventing the adsorption unit 60 from generating magnetic attraction and affecting the opening of the hatch 30.

[0072] In one embodiment, the adsorption unit 60 includes at least one first adsorption unit 61 and at least one second adsorption unit 62. The at least one first adsorption unit 61 is arranged along the edge of the surface of the hatch 30 toward the hatch frame 20, and the at least one second adsorption unit 62 is arranged along the surface of the hatch frame 20 toward the hatch 30. When the hatch 30 rotates and approaches the hatch frame 20, the number of the first adsorption unit 61 and the second adsorption unit 62 are equal and they are set in a one-to-one correspondence.

[0073] like Figure 1 and Figure 2 As shown, the hatch 30 is a plate-shaped interface in order to close the receiving cavity, and the frame 20 is a frame structure in order to place objects into the receiving cavity.

[0074] It is understandable that the first adsorption unit 61 is arranged on the edge of the surface of the hatch 30 facing the frame 20, so that when the hatch 30 is rotated, the first adsorption unit 61 on the hatch 30 faces the frame 20. When the first adsorption unit 61 generates magnetic attraction, it can attract the first adsorption unit 61 to the frame 20 or the second adsorption unit 62, thereby causing the hatch 30 to rotate and move closer to the frame 20. When the first adsorption unit 61 is attracted, the magnetic attraction can also cause the hatch 30 to rotate and move closer to the hatch frame.

[0075] In one embodiment, the first adsorption unit 61 is an electromagnet, and the second adsorption unit is a magnetic material suction plate. When the electromagnet is powered and generates magnetic attraction, the first adsorption unit 61 and the second adsorption unit 62 are arranged opposite to each other, so that the electromagnet attracts the suction plate, thereby causing the hatch 30 to rotate and move closer to the hatch frame 20.

[0076] Similarly, the first adsorption unit 61 can be a magnetic material adsorption plate, and the second adsorption unit 62 can be an electromagnet.

[0077] When both the first adsorption unit 61 and the second adsorption unit 62 are electromagnets, the preset threshold can be increased. That is, the angle between the hatch 30 and the frame 20 is larger than the angle between the hatch 30 and the frame 20 when either the first adsorption unit 61 or the second adsorption unit 62 is an electromagnet. The first adsorption unit 61 and the second adsorption unit 62 generate magnetic attraction simultaneously, so that the hatch 30 can be driven to rotate in response to the magnetic attraction generated by the first adsorption unit 61 and the second adsorption unit 62 at a larger angle, thereby improving the response efficiency of the hatch 30.

[0078] It should be noted that if the hatch 30 and / or the hatch frame 20 are made of magnetic material, then the hatch 30 and / or the hatch frame 20 can be used as a suction plate.

[0079] It should be noted that when neither the hatch 30 nor the frame 20 is made of magnetic material, the first adsorption unit 61 or the second adsorption unit 62 that is attracted needs to be made of magnetic material and installed on the hatch 30 or the frame 20. This makes it easier for the hatch 30 to be subjected to magnetic attraction, so that it can rotate and fit tightly against the frame 20.

[0080] like Figure 6 As shown, the first adsorption unit 61 is disposed on the surface of the hatch 30 facing the hatch frame 20, and the second adsorption unit 62 is disposed on the surface of the hatch frame 20 facing the hatch 30.

[0081] It is understandable that both the first adsorption unit 61 and the second adsorption unit 62 are disposed on the surface, so as to ensure the sensitivity of the adsorption between the first adsorption unit 61 and the second adsorption unit 62 when the first adsorption unit 61 and the second adsorption unit 62 are attracted to each other.

[0082] In one embodiment, the power supply unit 40 and the control unit are both connected to the first adsorption unit 61, and / or the power supply unit 40 and the control unit are both connected to the second adsorption unit 62.

[0083] It is understandable that when both the power supply unit 40 and the control unit are connected to the first adsorption unit 61, the power supply unit 40 only supplies power to the first adsorption unit 61, so that the first adsorption unit 61 generates magnetic attraction, and the first adsorption unit 61 attracts the second adsorption unit 62, which facilitates the rotation of the hatch 30 and its fit against the hatch frame 20.

[0084] It is understandable that when both the power supply unit 40 and the control unit are connected to the second adsorption unit 62, the power supply unit 40 only supplies power to the second adsorption unit 62, so that the second adsorption unit 62 generates magnetic attraction, and the second adsorption unit 62 attracts the first adsorption unit 61, which facilitates the rotation of the hatch 30 and fits the hatch frame 20.

[0085] It is understood that both the power supply unit 40 and the control unit are connected to the first adsorption unit 61, and both the power supply unit 40 and the control unit are connected to the second adsorption unit 62. The power supply unit 40 supplies power to both the first adsorption unit 61 and the second adsorption unit 62 at the same time. Both the first adsorption unit 61 and the second adsorption unit 62 generate magnetic attraction and attract each other, thereby facilitating the rotation of the hatch 30 and its fit against the hatch frame 20, while also increasing the response position range of the hatch 30.

[0086] In one embodiment, the control unit includes a sensing unit 70 and a main control unit 50: The sensor 70 is disposed on the frame 20 and / or the door 30. The sensor 70 is communicatively connected to the main control unit 50. The sensor 70 is configured to detect the position information between the door 30 and the frame 20 when the door 30 rotates and approaches the frame 20, and transmit the position information to the main control unit 50. The main control unit 50 is located on the frame 20 and / or the door 30. The main control unit 50 is configured to receive position information and generate an adsorption command when the position information reaches a preset threshold.

[0087] like Figure 3 As shown, the sensing unit 70 is used to detect the position information between the hatch 30 and the frame 20, and the main control unit 50 is used to receive the position information detected by the sensing unit 70 and judge the position information. When the position information reaches a preset threshold, the main control unit 50 generates an adsorption command.

[0088] In one embodiment, the sensing unit 70 is disposed on the cabin frame 20, and the main control unit 50 is disposed on the cabin frame 20.

[0089] In one embodiment, the sensing unit 70 is disposed on the cabin frame 20, and the main control unit 50 is disposed on the cabin door 30.

[0090] In one embodiment, the sensing unit 70 is disposed on the hatch 30, and the main control unit 50 is disposed on the hatch 30.

[0091] In one embodiment, the sensing unit 70 is disposed on the hatch 30, and the main control unit 50 is disposed on the hatch frame 20.

[0092] Because the sensing unit 70 and the main control unit 50 are connected by communication, the relative positional relationship between the sensing unit 70 and the main control unit 50 is not required.

[0093] In one embodiment, the main control unit is an ECU (Electronic Control Unit). The ECU receives position information transmitted by the sensing unit 70 and determines whether to generate an adsorption command based on a preset threshold and the position information.

[0094] It should be noted that location information can be either distance information or angle information.

[0095] When the position information is distance information, the sensing unit 70 can be a distance sensor. During the rotation of the hatch 30, the distance sensor detects the distance information between the hatch 30 and the hatch frame 20.

[0096] When the position information is angle information, the sensing unit 70 can be an angle sensor, which detects the rotation angle of the hatch 30 during the rotation of the hatch 30.

[0097] It should be noted that the hatch 30 is connected to the hatch frame 20 via a rotating shaft, and an angle sensor is installed on the rotating shaft. When the hatch 30 rotates, the angle of rotation of the synchronously rotating shaft is detected.

[0098] In one embodiment, the sensing element 70 is disposed on the surface of the frame 20 facing the hatch 30, and the sensing element 70 is exposed on the surface of the frame 20; or, The sensor is disposed on the surface of the hatch 30 facing the frame 20, and the sensor 70 is exposed on the surface of the hatch 30.

[0099] like Figure 5 As shown, through holes are provided on the surface of the hatch 30 facing the frame 20 or the surface of the frame 20 facing the hatch 30. When the sensing unit 70 is installed on the frame 20 or the hatch 30, the sensing unit 70 is installed through the through holes.

[0100] Understandably, by partially exposing the sensing unit 70 on the surface of the hatch 30 or the hatch frame 20, the sensing unit 70 can accurately detect the positional information between the hatch 30 and the hatch frame 20 as the hatch 30 rotates and approaches the hatch frame 20, thereby improving the accuracy of detection.

[0101] In one embodiment, the sensing unit 70 is positioned away from the rotation center of the hatch 30.

[0102] When the position information is distance information, in order to improve the accuracy of the distance information detected by the sensing unit 70 and to make the detected distance information fit the rotation angle of the hatch 30, the sensing unit 70 is set away from the rotation center of the hatch 30.

[0103] It is understandable that the sensor 70 is located away from the rotation center of the hatch 30. That is, when the sensor 70 is installed on the hatch 30, the sensor 70 is located on the hatch 30 away from the rotation axis. When the sensor 70 is installed on the hatch frame, the sensor 70 is located on the hatch frame 20 away from the rotation axis.

[0104] Because the sensor 70 is far from the rotation center of the hatch 30, as the hatch 30 rotates and approaches the hatch frame 20, the sensor 70 can accurately detect the distance information between the hatch 30 and the hatch frame 20, so that the main control unit 50 can accurately issue an adsorption command, and the hatch 30 can rotate and fit into the hatch frame 20.

[0105] In one embodiment, the hatch 30 is provided with a first fastening part 81 at a position away from the rotation center of the hatch 30, and the hatch frame 20 is provided with a second fastening part 82 at a position away from the rotation center of the hatch 30. When the hatch 30 is attached to the hatch frame 20, the first fastening part 81 and the second fastening part 82 are connected.

[0106] It should be noted that the hatch 30 and the hatch frame 20 are mechanically fastened together.

[0107] Understandably, when the hatch 30 rotates and fits against the hatch frame 20, the first fastening part 81 and the second fastening part 82 are mechanically fastened together, thereby improving the airtightness of the hatch 30 in the enclosed cavity.

[0108] This utility model also proposes a vehicle, which includes a car door closing device. The specific structure of the car door closing device is as described in the above embodiments. Since this vehicle adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0109] It is understood that the vehicle 10 is provided with a receiving cavity, and the vehicle door closing device is connected to the vehicle 10 and closes the receiving cavity.

[0110] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model.
