Description

Technical Field

[0001] The utility model relates to the technical field of vehicle back door switch structure, and in particular to a vehicle back door opening trigger device. The utility model also relates to a vehicle comprising the vehicle back door opening trigger device. Background Art

[0002] The vehicle tailgate switch is a structure used to control the opening of the vehicle tailgate. The operability and durability of the vehicle tailgate switch structure will directly affect the user experience, so its performance is one of the important criteria for evaluating the overall quality of the vehicle.

[0003] At present, the common vehicle tailgate switch structure usually adopts the form of micro switch and glue potting package. In this vehicle tailgate switch structure, the micro switch is welded on the circuit board, the wiring harness on the circuit board passes through the base and is connected to the tailgate lock body, and finally the relevant parts are sealed with glue. After pressing the micro switch, a control signal is generated, which is transmitted to the control circuit of the tailgate lock body switch through the wiring harness, and the tailgate lock body is opened by the on and off of the control circuit.

[0004] As the use time increases, the plastic parts in the switch structure that are in contact with the glue-filled parts may shrink and deform due to changes in environmental conditions such as high temperature or humidity, which may cause cracks in the glue-filled parts and allow water to enter the micro switch. When water enters the micro switch, the pot pieces will oxidize and corrode, resulting in the inability to generate control signals, which in turn causes the switch to fail.

[0005] In the prior art, there are related documents reporting on technical solutions for sealing the back door switch of a vehicle. For example, an outer cover is set on the switch mounting seat, the button of the micro switch is against the middle position of the outer cover, the buckle of the outer cover is pressed against the mounting seat, and a sealing ring is set at the edge. However, after long-term use, this structure may still cause water to enter the micro switch due to aging or breakage of the sealing ring, which is not conducive to extending the service life of the back door switch of the vehicle. Utility Model Content

[0006] In view of this, the utility model aims to provide a vehicle tailgate opening trigger device, which can effectively reduce the risk of component oxidation and corrosion and extend the service life.

[0007] In order to achieve the above object, the technical solution of the utility model is implemented as follows:

[0008] The utility model discloses a vehicle back door opening trigger device, which is arranged on the back door to control the back door lock to open, and comprises:

[0009] A base, the base being held on the back door, and a sensing component being embedded in the base;

[0010] A trigger assembly, which can be driven to move closer to or farther from the base, and a ferromagnetic component is embedded in the trigger assembly;

[0011] When the ferromagnetic component moves with the trigger component to approach or move away from the sensing component, the sensing component generates a changing sensing signal to control the on and off of the rear door lock switch.

[0012] Furthermore, a housing is mounted on the base, and the trigger assembly is encapsulated in a space between the housing and the base;

[0013] At least a portion of the housing is configured to be flexible so as to deform inwardly when subjected to an external force to drive the trigger assembly to approach the base.

[0014] Furthermore, an upper protrusion extending toward the shell is provided on an edge of the base, and the upper protrusion has a beveled edge that seals with the shell.

[0015] Furthermore, an elastic member is provided between the base and the trigger assembly, and the elastic member elastically stores energy when the trigger assembly is close to the base.

[0016] Furthermore, the elastic members are arranged to be at least two distributed around the periphery of the ferromagnetic component.

[0017] Furthermore, an open groove is provided on the base, one end of the elastic member is embedded in the open groove, and the other end is connected to the trigger assembly.

[0018] Furthermore, the trigger assembly is provided with a limiting column extending toward the base, and the other end of the elastic member is sleeved on the limiting column.

[0019] Furthermore, when the trigger assembly moves closer to the base, at least a portion of the limiting column is inserted into the open groove.

[0020] Furthermore, a guide assembly is provided between the base and the trigger assembly to guide the trigger assembly to approach or move away from the base;

[0021] The trigger assembly has an extension portion extending toward the base at its edge; the guide assembly includes a slide groove formed on the extension portion, and a guide rod extending from the base toward the trigger assembly, and the guide rod is slidably disposed in the slide groove.

[0022] Compared with the prior art, the utility model has the following advantages:

[0023] The vehicle tailgate opening trigger device described in the utility model outputs different voltage values ​​to control the on-off of the vehicle tailgate lock switch circuit and realize the opening of the vehicle tailgate, by detecting the change of the magnetic field at different distances between the ferromagnetic component and the induction component when the ferromagnetic component in the trigger component approaches or moves away from the induction component on the base; in its structure, since the induction component is buried in the base, the structure has good sealing and waterproof properties, and avoids the use of glue filling, so there will be no problems such as cracking of the glue filling part, sealing failure and water ingress into the switch, and it has strong waterproof properties, which can effectively improve the overall service life.

[0024] In addition, the shell assembled on the base can form another sealing protection structure with the base, which further protects the trigger assembly arranged between the shell and the base, and more effectively improves the overall sealing of the utility model. The shell is at least partially set to a flexible material, which can improve the comfort and operating feel of the user when pressing on the shell. The bevel structure on the upper protrusion extending toward the shell on the edge of the base can form an interference fit structure with better sealing and waterproof properties after assembly with the shell, further improving the sealing of the first sealing structure in the utility model.

[0025] Secondly, an elastic member is arranged between the base and the trigger assembly, so that when the trigger assembly approaches the base, the elastic member is elastically compressed. When the external force acting on the trigger assembly disappears, the elastic member releases the elastic force, driving the trigger assembly to rebound and return to the initial position, thereby achieving automatic reset and improving convenience. Arranging the elastic member to be at least two located around the ferromagnetic component can improve the stability of the trigger assembly during the rebound and reset process, and is conducive to reducing blockage or jamming caused by insufficient rebound force or incorrect rebound force direction. An open groove is arranged on the base to achieve more stable installation of the elastic member while achieving installation and positioning of the elastic member.

[0026] Furthermore, by setting a limit column structure, it can play a limiting role in the installation of the elastic member, further avoiding the phenomenon of the elastic member being misplaced during use. The limit column is set as a structure that is at least partially inserted into the open groove as the trigger component moves closer to the base, which plays a limiting and guiding role in the movement of the trigger component, which is conducive to improving the smoothness of the movement of the trigger component and further avoiding the phenomenon of the elastic member being misplaced. By setting the guide component, it can play a guiding role in the movement of the trigger component closer to or away from the base, which is conducive to improving the smoothness of the movement of the trigger component.

[0027] In addition, the utility model also proposes a vehicle provided with the vehicle back door opening trigger device.

[0028] The vehicle described in the present invention has the same beneficial effects as the vehicle tailgate opening trigger device described above relative to the prior art, which will not be described in detail herein. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0053] Embodiment 1

[0054] The present embodiment relates to an opening trigger device for a vehicle tailgate, which realizes the opening trigger of the vehicle tailgate by adopting a non-direct contact inductive trigger structure, and seals some components inside the structure by an integrated injection molding process, thereby improving the sealing and waterproof properties, thereby achieving the purpose of extending the service life.

[0055] In terms of overall structure, the vehicle back door opening trigger device of this embodiment includes a base 1, a sensing component 2 and a trigger component 3. The sensing component 2 is embedded in the base 1 by injection molding, and the trigger component 3 can be operated to approach or move away from the sensing component 2.

[0056] As configured above, when the trigger component 3 approaches or moves away from the sensing component 2, the magnetic field of the sensing component 2 changes, and different voltage values ​​are output according to different distances of the trigger component 3 to control the on-off of the vehicle's rear door lock switch circuit, thereby opening the vehicle's rear door. In its structure, since the sensing component 2 is buried in the base, the structure has good sealing and waterproof properties, and avoids the use of glue filling, so there will be no problems such as cracking of the glue filling part, sealing failure, and water ingress into the switch. It has strong waterproof properties and can effectively improve the overall service life.

[0057] Based on the above overall design concept, specifically, in this embodiment, refer to Figure 2 and Figure 4 , the induction component 2 includes an integrated circuit board 201, a magnet 202, a conductive pin 203 and a Hall element 204. The integrated circuit board 201 is plastic-encapsulated and buried inside the base 1, the magnet 202 is used to generate a magnetic field, the Hall element 204 is used to generate an induced current, and the conductive pin 203 is electrically connected to the integrated circuit board 201 and extends to the outside of the base 1. When the trigger component 3 approaches or moves away from the base 1 (and the induction component 2 in the base 1), the magnetic field of the magnet 202 changes, and the Hall element 204 outputs different voltage values, which are amplified by the integrated circuit board 201 as an induction signal, and are transmitted to the control circuit of the vehicle's rear door lock switch through the conductive pin 203, and used as a signal to control the vehicle's rear door lock body switch, thereby realizing the function of controlling the opening of the vehicle's rear door.

[0058] Reference Figure 2 and Figure 5The trigger assembly 3 includes an inner shell 300, a ferromagnetic component 301, a limiting column 302 and an extension 303. The inner shell 300 can be made of a polymer material with insulation and waterproof properties. The middle position of the inner side surface of the inner shell 300 extends toward the base 1 to form a rectangular sealed space. The ferromagnetic component 301 is embedded in the sealed space of the inner shell 300 by injection molding. The ferromagnetic component 301 can be made of a material that can cause a change in magnetic flux and cause the Hall element 204 to generate an induced current. In this embodiment, the ferromagnetic component 301 is an iron solid rectangular block.

[0059] Reference Figure 2 In order to realize the automatic reset function and further improve the operating feel, in this embodiment, the opening trigger device of the vehicle back door further includes an elastic member 5. The elastic member 5 can be an elastic rubber column or a spring. In this embodiment, the elastic member 5 is a spring, which is installed between the trigger component 3 and the base 1. When the trigger component 3 approaches the base 1, the spring is compressed and elastically stores energy. After the pressure acting on the trigger component 3 is released, the spring applies elastic force to the trigger component 3 and returns to the initial position, so that the trigger component 3 has the function of automatic reset and further improves the operating feel of the utility model.

[0060] In this embodiment, two elastic members 5 are arranged along the periphery of the ferromagnetic member 301, and are symmetrical about the geometric center of the ferromagnetic member 301. By increasing the number of elastic members 5 and symmetrically arranging the elastic members 5 along the ferromagnetic member 301, the stability of the resetting process of the trigger component 3 can be increased, which is conducive to reducing the possibility of blocking and jamming of the trigger component 3 during the resetting process.

[0061] In order to reduce the phenomenon of misalignment of the elastic member 5, a limiting column 302 is provided to extend from the trigger assembly 3 toward the base 1. The limiting column 302 can be made of the same material as the inner shell 300 of the trigger assembly 3 by injection molding. The number of limiting columns 302 is consistent with the number of elastic members 5. The end of the elastic member 5 away from the base 1 is sleeved on the limiting column 302. The outer surface of the limiting column 302 is evenly provided with a plurality of convex ridges parallel to the axial direction along the circumferential direction. In this embodiment, the number of convex ridges is four. The convex ridges abut against the inner ring of the elastic member 5 to form a more stable assembly structure. The limiting column 302 has a limiting effect on the elastic member 5, which is helpful to avoid the phenomenon of misalignment of the elastic member 5 during use.

[0062] Reference Figure 1 and Figure 2, in order to further improve the sealing and waterproof properties and the operating feel, a shell 4 is assembled on the base 1. The trigger assembly 3 is encapsulated in the space between the shell 4 and the base 1. The portion of the shell 4 that is opposite to the trigger assembly 3 is made of a flexible material. When the shell 4 is subjected to external force, it will deform inward and drive the trigger assembly 3 to approach the base 1. There are bolt holes at both ends of the shell 4, and it is detachably connected to the base 1 by bolts 401. The portion of the shell 4 that contacts the base 1 can be made of a flexible material, so that it fits tightly with the base 1 to form another sealing protection structure. The two ends of the shell 4 extend to both sides to form mounting ears 402, and the mounting ears 402 can be used to install the utility model on the back door of the vehicle. The shell 4 protects the trigger assembly 3 and further improves the overall sealing of the present application. Part of the shell 4 is made of a flexible material, which can further improve the operating feel of the utility model.

[0063] Reference Figure 2 and Figure 3 , for the purpose of further improving the sealing and waterproof properties and reducing the phenomenon of misalignment of the elastic member 5, the base 1 includes an upper protrusion 101, a hypotenuse 1011 and an open groove 102. Among them, the edge of the base 1 has an upper protrusion 101 extending in the direction of the shell 4. The upper protrusion 101 is made of the same material as the base 1 and can be formed by injection molding. The upper surface or side of the upper protrusion 101 has a hypotenuse 1011 that is sealed with the shell 4. In this embodiment, the hypotenuse 1011 is arranged on the upper surface of the upper protrusion 101, because it can form an interference fit with the shell 4 under the pressure of the bolts 401 that are penetrated on the base 1 and the shell 4, so as to have better sealing. The cross-sectional shape of the hypotenuse 1011 can be an isosceles right triangle with the longest side parallel to the horizontal plane, so as to increase the contact area with the shell 4. The part of the shell 4 that is in direct contact with the hypotenuse 1011 can be set as a flexible material to fit the hypotenuse 1011 tightly, so as to further improve the sealing of the sealing guarantee structure.

[0064] The base 1 has an open groove 102. The number of the open grooves 102 is the same as the number of the elastic members 5. The open grooves 102 may be cylindrical grooves provided on the base 1. The diameter of the open groove 102 is the same as the outer diameter of the elastic member 5. One end of the elastic member 5 is embedded in the open groove 102. The open groove 102 plays an auxiliary positioning role in the installation of the elastic member 5, simplifies the installation process, and is also helpful in preventing the elastic member 5 from being misplaced during use.

[0065] Reference Figure 2 and Figure 5In order to improve the smoothness of the movement of the trigger assembly 3, the length of the limit column 302 is set to be able to at least partially insert into the open groove 102 when the trigger assembly 3 moves close to the base 1. By setting the length of the limit column 302 to be able to partially insert into the open groove 102, it can play a guiding role for the trigger assembly 3, increase the smoothness of the movement of the trigger assembly 3, and further avoid the occurrence of the phenomenon of misalignment of the elastic member 5.

[0066] Reference Figure 2 and Figure 5 In order to improve the smoothness of the movement of the trigger assembly 3, a guide assembly 6 is also provided between the base 1 and the trigger assembly 3. The trigger assembly 3 is provided with an extension portion 303 extending in the direction of the base 1. The extension portion 303 can be made of the same material as the inner shell 300 by injection molding. The guide assembly 6 includes a slide 601 and a guide rod 602. Among them, the slide 601 is provided on the extension portion 303, and the length direction of the slide 601 is consistent with the movement direction of the trigger assembly 3. The guide rod 602 is extended from the base 1 to the trigger assembly 3, and can be made of the same material as the base 1 by injection molding. The guide rod 602 is slidably provided in the slide 601, and at least part of the outer surface of the guide rod 602 is partially in contact with the inner wall of the slide 601. The guide assembly 6 guides the movement process of the trigger assembly 3, and further increases the smoothness of the movement process of the guide assembly 6.

[0067] Reference Figure 6 , SW is a signal control switch. The signal control switch SW selects the sensing component 2 as the signal source. After detecting the sensing signal from the sensing component 2, the signal control switch SW is closed, the circuit is turned on, and the rear door lock of the vehicle is opened.

[0068] Embodiment 2

[0069] This embodiment relates to a vehicle, including a tailgate, on which the vehicle tailgate opening triggering device in the first embodiment is mounted.

[0070] In this embodiment, by using the vehicle back door opening trigger device of the first embodiment on the back door, it is possible to control the opening of the vehicle back door without using a micro switch and a glue-filled packaging structure. Since the injection-molded integrated structure has good waterproof performance and does not have the sealing failure problem caused by cracking of the glue-filled packaging part, it has a longer service life than the prior art.

[0071] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
