[0008] The vehicle door hinge assembly of the present application is connected to the vehicle body based on a fixed seat, and the two opposite ends of the slide rod along its own axis are respectively connected to the drive device and the vehicle door. By setting a guide rail and a guide member in both the fixed seat and the slide rod, and setting the guide member and the guide rail to cooperate with each other, the slide rod drives the vehicle door to move relative to the vehicle body under the drive of the drive device, that is, the door can be controlled to open or close by controlling the movement of the slide rod. By setting the guide rail to have a target trajectory, the door can be opened or closed with a preset action. The vehicle door hinge assembly of the present application has a simple structure and a small number of components, which is conducive to processing and assembly, and reduces costs. At the same time, the vehicle door hinge assembly of the present application reduces the control accuracy requirements of the drive device through the structural control mechanism of the guide rail and the guide member, and further reduces costs.

[0009] In one embodiment, the guide rail includes a straight segment.

[0010] In this embodiment, by arranging a straight line segment in the guide rail, the slide rod is driven by the driving device to reciprocate along the axial direction of the slide rod relative to the fixing seat to push open or close the door.

[0013] In one embodiment, the guide member includes a rolling portion, the guide rail is a groove structure, the rolling portion cooperates with the groove structure, and can slide along the guide rail.

[0014] In this embodiment, the guide member includes a rolling portion, and the corresponding guide rail is a groove structure, so as to use a simple structure to control the movement trajectory of the slide bar, which is beneficial to processing and assembly and reduces costs.

[0015] In one embodiment, the slide bar is inserted into the inner hole of the fixing seat, and the driving device is used to drive the slide bar to reciprocate relative to the fixing seat;

[0016] Wherein, a guide rail is arranged on the fixed seat, and a guide piece is arranged on the slide bar;

[0018] When the guide piece cooperates with the spiral section, the slide bar moves along its own axial direction relative to the fixed seat, and simultaneously rotates along its own circumferential direction relative to the fixed seat.

[0019] In this embodiment, the guide rail is arranged on the fixed seat, and the guide member is arranged on the slide rod, so that the reliability of the guide rail and the guide member can be ensured. When the guide member is arranged to cooperate with the straight section, the slide rod moves along its own axial direction relative to the fixed seat, so that the slide rod can first move horizontally along its own axial direction in the straight section to drive the door to push forward, and push the door away from the body to obtain rotation space. Then, when the guide member is arranged to cooperate with the spiral section, the slide rod moves along its own axial direction relative to the fixed seat, and at the same time rotates along its own circumference relative to the fixed seat, so as to drive the door to achieve outward extension and rotation, thereby realizing the action of opening the door relative to the body rotor.

[0020] In one embodiment, along the circumference of the slide rod, the angle between the starting point and the end point of the spiral segment is between 60° and 120°.

[0021] In this embodiment, by controlling the angle between the starting point and the end point of the spiral segment, the rotation angle of the slide bar relative to the fixed seat can be controlled.

[0022] In one embodiment, the guide rail further includes a holding section, which is located at an end of the spiral section away from the straight section, and the holding section is parallel to the straight section.

[0024] In one embodiment, there are plural rolling parts and plural guide rails, and the rolling parts are arranged along the circumference of the slide bar.

[0025] In this embodiment, the provision of multiple rolling parts and guide rails can provide more stable guidance for the sliding and rotation of the slide rod, thereby improving the reliability of the door hinge assembly.

[0026] In one embodiment, a roller is provided on the outer circumference of the slide rod, and the roller is used to be rotatably connected with the guide member.

[0027] In this embodiment, by arranging a roller rotatably connected to the guide member on the outer circumference of the slide rod, the movement effect of the slide rod relative to the fixed seat is improved, and the processing difficulty of the door hinge assembly can be reduced, saving costs.

[0028] In one embodiment, the fixed seat includes a left seat body and a right seat body, the left seat body is provided with a left arc-shaped groove, the right seat body is provided with a right arc-shaped groove, the left seat body and the right seat body are fixedly connected, and the left arc-shaped groove and the right arc-shaped groove are spliced ​​to form an inner hole.

[0029] In this embodiment, the left seat body and the right seat body are processed separately by splicing, which is conducive to processing the groove structure in the left arc groove and / or the right arc groove, reducing the processing difficulty and ensuring the processing accuracy.

[0030] In one embodiment, the driving device includes a motor and a transmission mechanism, and the motor is connected to the sliding rod through the transmission mechanism.

[0031] In this embodiment, the driving device can be powered by a motor, and a transmission mechanism can be used to convert the rotational motion output by the motor into the reciprocating motion of the slide rod.

[0032] In one embodiment, the transmission mechanism includes a gear and a rack, the rack is connected to the slide bar, and the rack and the slide bar are coaxially arranged, and the motor is connected to the rack through the gear.

[0033] In this embodiment, the gear and rack cooperate to realize the reversing function inside the transmission mechanism, thereby achieving the effect that the motor drives the slide bar to reciprocate relative to the fixed seat through the transmission mechanism. The gear and rack have simple structures and are easy to manufacture and assemble.

[0034] In one embodiment, the door hinge assembly further includes a connecting member, which is disposed between the rack and the slide rod so that the rack and the slide rod can rotate relative to each other.

[0035] In this embodiment, because the slide rod rotates relative to the rack when the rack pushes the slide rod, a connecting piece is provided between the rack and the slide rod to reduce the friction between the slide rod and the rack and reduce the wear of the door hinge assembly.

[0036] In one embodiment, the connecting member is a bidirectional thrust ball bearing.

[0037] In this embodiment, the bidirectional thrust ball bearing has a relatively strong pressure bearing capacity and can reliably transmit the power provided by the rack to the slide rod.

[0038] In one embodiment, the transmission mechanism is a screw-nut mechanism.

[0059] At present, most car doors are opened by rotating side opening, but as people are increasingly pursuing individuality and fashion, the rotary door has come into being. The rotary door can usually be opened by rotating 90 degrees around the door fulcrum. When opening, the door can be pushed forward, extended outward, rotated, and other variable door opening actions make the car look cooler, more fashionable, and more high-end; at the same time, it can also save space on both sides of the vehicle to the greatest extent, solving the problem of inconvenience for passengers to get on and off the car when the parking space is narrow, and thus it is favored by consumers.

[0060] The present application provides a vehicle, including a vehicle body, a door, and a door hinge assembly. The main structure of the door hinge assembly is fixed to the side of the vehicle body, and the door hinge assembly is connected between the vehicle body and the door to drive the door to open or close. Specifically, the door hinge assembly of the present application can be, but is not limited to, fixed to the front fender of the vehicle and fixedly connected to the door to achieve the action of opening the door relative to the rotor of the vehicle body. The structure of the door hinge assembly of the present application and the possible beneficial effects will be described in detail below in conjunction with the accompanying drawings.

[0061] Please refer to Figure 1 and Figure 3 ,in Figure 1 This is a schematic diagram of a working scene of a vehicle door hinge assembly 100 provided in one embodiment of the present application; Figure 2 This is a structural schematic diagram of a vehicle door hinge assembly 100 provided in one embodiment of the present application; Figure 3 It is a partial cross-sectional view of a vehicle door hinge assembly 100 provided in one embodiment of the present application.

[0062] like Figures 1 to 3 As shown, in one embodiment, the vehicle door hinge assembly 100 of the present application includes a driving device 10, a fixing seat 20 and a sliding rod 30. The fixing seat 20 is suitable for connecting with a vehicle, and the fixing seat 20 includes an inner hole 21 that cooperates with the sliding rod 30. The sliding rod 30 is inserted into the inner hole 21 of the fixing seat 20, and one end of the sliding rod 30 along its own axial direction is rotatably connected to the driving device 10, and the other end of the sliding rod 30 along its own axial direction is suitable for fixed connection with the vehicle door. The driving device 10 can be used to provide a driving force to the sliding rod 30 along the axial direction of the sliding rod 30, and enable the sliding rod 30 to reciprocate relative to the fixing seat 20.

[0063] It can be understood that by setting the sliding rod 30 to be rotatably connected with the driving device 10, it can ensure that the sliding rod 30 can slide back and forth relative to the fixing seat 20, and can also make the sliding rod 30 rotate relative to the driving device 10, so as to drive the door fixed to the sliding rod 30 to rotate relative to the driving device 10. At the same time, the sliding rod 30 can cooperate with the fixing seat 20 to control the running trajectory of the sliding rod 30, so as to realize the action of opening or closing the door relative to the body rotor under the drive of the driving device 10.

[0064] It should be noted that, in another embodiment, the slide rod 30 does not need to be inserted into the inner hole 21 of the fixed seat 20, or it can be understood that the fixed seat 20 does not need to be provided with an inner hole 21, as long as the slide rod 30 can move along the target trajectory relative to the fixed seat 20, the present application does not make any special limitations on this.

[0065] For details, please refer to Figure 4 , Figure 4 It is a schematic diagram of the exploded structure of a vehicle door hinge assembly 100 provided in one embodiment of the present application.

[0066] like Figures 1 to 4 As shown, in a possible embodiment, the vehicle door hinge assembly 100 of the present application includes a guide rail 40 and a guide member 50 that cooperate with each other. The guide rail 40 and the guide member 50 can be arranged on both the slide bar 30 and the fixed seat 20. Exemplarily, the guide rail 40 can be arranged on the inner circumference of the inner hole 21 of the fixed seat 20, and the guide rail 40 extends along the axial direction of the slide bar 30, and a target track is provided on the guide rail 40. The guide member 50 can be fixed to the outer circumference of the slide bar 30, and the guide member 50 can move along the target track of the guide rail 40 after being assembled with the guide rail 40, thereby guiding the sliding direction of the slide bar 30 relative to the fixed seat 20. That is, the slide bar 30 is assembled with the fixed seat 20 through the guide member 50, and the guide rail 40 in the fixed seat 20 can limit the movement track of the slide bar 30 under the drive of the driving device 10. At the same time, in this embodiment, since the inner circumference of the inner hole 21 of the fixing seat 20 is easier to process the structure of the guide rail 40 than the outer circumference of the sliding rod 30, setting the guide rail 40 on the inner circumference of the inner hole 21 of the fixing seat 20 can reduce the processing difficulty of the door hinge assembly 100 and save costs.

[0067] It can be understood that the present application sets a target track in the guide rail 40 and cooperates with the guide member 50 so that the slide rod 30 drives the door to open or close under the drive of the driving device 10. The door hinge assembly 100 of the present application has a simple structure and a small number of components, which is convenient for processing and assembly and can reduce costs. At the same time, the door hinge assembly 100 of the present application controls the movement accuracy of the mechanism through the structure of the guide member 50 and the guide rail 40, which reduces the control accuracy requirements of the driving device 10 and further reduces costs.

[0068] For further information, please refer to Figure 5 and Figure 6 ,in, Figure 5 Schematic diagram of the cross-sectional structure of a fixing seat 20 provided in one embodiment of the present application. Figure 6 Schematic diagram of the structure of a guide rail 40 provided in one embodiment of the present application.

[0069] like Figures 1 to 6As shown, the target trajectory of the guide rail 40 of the present application includes a straight section 41 and a spiral section 42. The spiral section 42 is arranged at one end of the straight section 41 close to the door, that is, the straight section 41 is closer to the drive device 10 than the spiral section 42. When the guide member 50 moves to the straight section 41, the slide bar 30 can move relative to the fixed seat 20 along its own axial direction under the drive of the drive device 10; when the guide member 50 moves to the spiral section 42, the slide bar 30 can move relative to the fixed seat 20 along its own axial direction under the drive of the drive device 10, and simultaneously rotate relative to the fixed seat 20 along its own circumferential direction. That is, the slide bar 30 can first move horizontally along its own axial direction in the straight section 41 to drive the door to push forward, push the door away from the body to obtain a rotation space; then move along the length direction of the guide rail 40 in the spiral section 42 and simultaneously rotate relative to the fixed seat 20 along the axis of the inner hole 21 to drive the door to achieve outward extension and rotation, thereby realizing the door relative to the body rotor opening action.

[0070] It can be understood that the vehicle door hinge assembly 100 of the present application drives the slide bar 30 to move in the fixed seat 20 through the driving device 10. Among them, a guide member 50 and a guide rail 40 that cooperate with each other are provided between the inner circumference of the inner hole 21 of the fixed seat 20 and the outer circumference of the slide bar 30. Through the cooperation of the guide member 50 and the guide rail 40, the timing of starting and ending the rotation action of the slide bar 30 during the movement can be controlled, and the running trajectory of the slide bar 30 can be controlled to drive the vehicle door to realize its opening action relative to the body rotor.

[0071] It should be noted that the arrangement positions of the guide member 50 and the guide rail 40 in the above embodiment are only introduced as examples, that is, the arrangement positions of the guide member 50 and the guide rail 40 can be adaptively adjusted according to the actual application scenario. For example, in a possible embodiment of the present application, the guide member 50 can be arranged on the inner circumference of the inner hole 21 of the fixing seat 20, and the guide rail 40 can be arranged on the outer circumference of the slide bar 30, which can also realize the control of the timing of starting and ending the rotation action of the slide bar 30 during the movement, and control the running trajectory of the slide bar 30.

[0072] Furthermore, in a possible embodiment, the guide rail 40 is configured as a groove structure 44, and the guide member 50 includes a rolling portion 51. The rolling portion 51 is embedded in the groove structure 44 and can move along the groove structure 44. The rolling portion 51 cooperates with the groove structure 44 to achieve control of the movement trajectory of the slide bar 30 by the guide rail 40 and the guide member 50. It can be understood that the structures of the groove structure 44 and the rolling portion 51 are relatively simple, which is conducive to processing and assembly, and can further reduce costs.

[0073] Based on the guide rail 40 being arranged on the inner circumference of the inner hole 21 of the fixing seat 20, that is, the groove structure 44 is arranged on the inner circumference of the inner hole 21 of the fixing seat 20. It can be understood that since the slide bar 30 is used as the power input shaft for opening the door, grooving on the slide bar 30 may affect the strength of the slide bar 30, thereby reducing the reliability of the door hinge assembly 100. In this embodiment, the groove structure 44 is arranged on the inner circumference of the inner hole 21 of the fixing seat 20 to solve the above problem, so as to improve the reliability of the door hinge assembly 100.

[0074] In a specific embodiment, the rolling portion 51 can be configured as a roller structure.

[0075] In a possible embodiment, along the circumference of the slide bar 30, the angle between the starting point and the end point of the spiral segment 42 is between 60° and 120°. It can be understood that in this embodiment, by controlling the angle between the starting point and the end point of the spiral segment 42, the rotation angle of the slide bar 30 relative to the fixing seat 20 can be controlled, thereby controlling the rotation angle of the door relative to the vehicle body. The spiral segment 42 within this angle range can ensure that the door rotates and opens relative to the vehicle body.

[0076] like Figures 1 to 6 As shown, in one embodiment, the guide rail 40 further includes a holding section 43. The holding section 43 is located at one end of the spiral section 42 away from the straight section 41, and the holding section 43 is also parallel to the straight section 41. When the guide member 50 moves from the spiral section 42 to the holding section 43, the rotation angle of the slide bar 30 relative to the fixed seat 20 remains fixed. That is, the slide bar 30 stops rotating at the holding section 43.

[0077] It can be understood that in this embodiment, the retaining section 43 can form a self-locking function for the guide member 50, so that after the slide rod 30 completes the rotation relative to the fixed seat 20, it can maintain the rotation angle relative to the fixed seat 20 to prevent falling back, thereby ensuring that the door rotor is firmly fixed to the vehicle body in a preset posture after opening.

[0078] exist Figure 4 In the illustrated embodiment, there are two guide rails 40 and two guide members 50. That is, there are two groove structures 44 and two rolling portions 51. Each groove structure 44 extends parallel to the axial direction of the slide bar 30, and two rolling portions 51 are arranged on both sides of the slide bar 30 along the circumferential direction of the slide bar 30, and each rolling portion 51 is embedded in one groove structure 44. It can be understood that in this embodiment, a plurality of rolling portions 51 and a plurality of groove structures 44 are provided to cooperate with each other, so as to provide a more stable guide for the movement and rotation of the slide bar 30 and improve the reliability of the door hinge assembly 100.

[0079] It should be noted that the number of groove structures 44 and rolling parts 51 in the above embodiment is only introduced as an example, that is, in other embodiments of the present application, the number of groove structures 44 and rolling parts 51 can be one or more, and the present application does not specifically limit this.

[0080] like Figure 4 As shown, in a possible embodiment, when the rolling portion 51 is disposed on the outer circumference of the slide bar 30 and the groove structure 44 is disposed on the inner circumference of the inner hole 21 of the fixing seat 20, a roller 31 may be convexly disposed on the outer circumference of the slide bar 30. The roller 31 is used to be rotatably connected with the rolling portion 51. It can be understood that the roller 31 is disposed on the outer circumference of the slide bar 30 so as to fix the rolling portion 51 to the slide bar 30.

[0081] Specifically, the rolling portion 51 can be configured as a roller bearing, the inner ring of the roller bearing is connected to the roller 31, and the outer ring is embedded in the groove structure 44. It can be understood that configuring the rolling portion 51 as a roller bearing can ensure that the rolling portion 51 and the groove structure 44 cooperate with each other to guide the slide bar 30 to move relative to the fixed seat 20, and can also reduce the friction between the rolling portion 51 and the groove structure 44, so that the movement of the slide bar 30 is smoother.

[0082] like Figure 4 As shown, in a possible embodiment, the fixing seat 20 includes a left seat body 22 and a right seat body 23. The left seat body 22 is provided with a left arc-shaped groove 221, and the right seat body 23 is provided with a right arc-shaped groove 231. The left seat body 22 and the right seat body 23 are fixedly connected, and the left arc-shaped groove 221 and the right arc-shaped groove 231 are spliced ​​to form an inner hole 21. Specifically, bolt holes 24 are provided at corresponding positions of the four corners of the left seat body 22 and the right seat body 23, and bolts 25 pass through the bolt holes 24 to splice and fix the left seat body 22 and the right seat body 23.

[0083] It can be understood that in this embodiment, the left seat body 22 and the right seat body 23 are processed separately by splicing, which can not only ensure the overall strength of the fixed seat 20, but also facilitate the processing of the groove structure 44 in the left arc groove 221 and / or the right arc groove 231, which can reduce the processing difficulty and ensure the processing accuracy.

[0084] Please look back Figure 4 In a possible embodiment, the driving device 10 of the present application includes a motor 11 and a transmission mechanism 12. The transmission mechanism 12 is connected between the motor 11 and the slide bar 30, and the motor shaft of the motor 11 rotates and drives the slide bar 30 to reciprocate relative to the fixed seat 20 through the transmission mechanism 12.

[0085] It can be understood that in this embodiment, the motor 11 is used to provide power to the slide bar 30, and the transmission mechanism 12 is used to convert the rotational motion output by the motor 11 into the reciprocating motion of the slide bar 30. Based on the advantages of motor drive such as fast response speed, high efficiency, and higher precision, the use of the motor 11 to provide power can enable the slide bar 30 to quickly drive the door to open, while also improving the position accuracy of the movement of the slide bar 30 and accurately controlling the magnitude of the driving force, so as to improve the user experience.

[0086] It should be noted that, in the above-mentioned embodiment, only the motor 11 is used as an example to illustrate the possible driving mode of the driving device 10 of the present application, but the driving mode of the driving device 10 of the present application is not limited to this. That is, in other embodiments of the present application, the driving mode of the driving device 10 can be adaptively adjusted according to actual needs, and the present application does not make any special restrictions on this. For example, in another embodiment, the driving mode of the driving device 10 of the present application can be driven by a cylinder or an oil cylinder, which can also drive the movement of the slide rod 30 in the fixed seat 20.

[0087] like Figure 2 As shown, in a possible embodiment, the transmission mechanism 12 includes a rotating input member 121 and a sliding output member 122. The motor 11 is in transmission connection with the rotating input member 121, that is, the motor 11 shaft of the motor 11 is fixedly connected with the rotating input member 121. The rotating input member 121 is also in transmission connection with the sliding output member 122, and one end of the slide bar 30 is in transmission connection with the sliding output member 122, and the axis of the slide bar 30 and the axis of the sliding output member 122 are located on the same horizontal line, and the slide bar 30 reciprocates along its own axial direction relative to the fixed seat 20 under the drive of the sliding output member 122.

[0088] It can be understood that in this embodiment, the transmission mechanism 12 realizes the reversing function through the cooperation of the rotating input member 121 and the sliding output member 122, thereby achieving the effect of the motor 11 driving the slide rod 30 to reciprocate relative to the fixed seat 20 through the transmission mechanism 12.

[0089] Specifically, in a possible embodiment, the transmission mechanism 12 is a gear rack mechanism. That is, the rotation input member 121 is set as a gear, and the sliding output member 122 is set as a rack, and the gear and the rack are meshed with each other to realize the conversion of the rotational motion of the motor shaft of the motor 11 into the reciprocating motion of the slide rod 30. It can be understood that the gear rack mechanism can realize the reversing function of the transmission mechanism 12 of the present application, and the structure is relatively simple, which is conducive to manufacturing and assembly.

[0090] It should be noted that, in another embodiment, the transmission mechanism 12 may also be a screw-nut mechanism, which can also ensure the realization of the reversing function of the transmission mechanism 12 and also has the advantages of simple structure and easy manufacture and assembly.

[0091] Please cooperate Figure 4 As shown, in a possible embodiment, the vehicle door hinge assembly 100 further includes a connecting member 60. The connecting member 60 is disposed between the sliding output member 122 and the slide rod 30, and enables the sliding output member 122 to rotate relative to the slide rod 30.

[0092] Specifically, in one embodiment, the connecting member 60 may be configured as a bearing, and the inner ring and the outer ring of the bearing are fixedly connected to the sliding output member 122 and the sliding rod 30 respectively.

[0093] It can be understood that in this embodiment, because the sliding output member 122 rotates relative to the sliding output member 122 during the process of pushing the sliding rod 30, a bearing is provided between the sliding output member 122 and the sliding rod 30, which can reduce the friction between the sliding rod 30 and the sliding output member 122 and reduce the wear of the door hinge assembly 100.

[0094] It should be noted that the form of the connecting member 60 in the above embodiment is only used as an exemplary introduction. In some other embodiments, the connecting member 60 may not be a bearing, as long as the relative rotation between the sliding rod 30 and the sliding output member 122 can be ensured.

[0095] At the same time, the connection relationship between the connecting member 60 arranged in the form of a bearing and the sliding output member 122 and the sliding rod 30 is only introduced as an example, that is, in another embodiment of the present application, the inner ring of the bearing can be fixedly connected to the sliding rod 30, and the outer ring of the bearing can be fixedly connected to the sliding output member 122, which can also achieve the effect of reducing the friction between the sliding rod 30 and the sliding output member 122.

[0096] In one embodiment, the connecting member 60 is a bidirectional thrust ball bearing. It is understandable that, based on the relatively strong pressure bearing capacity of the bidirectional thrust ball bearing, setting the connecting member 60 as a bidirectional thrust ball bearing can reliably transmit the power provided by the sliding output member 122 to the sliding rod 30.

[0097] Please look back Figure 1 In one embodiment, the fixing base 20 of the door hinge assembly 100 is fixed to the vehicle body (not shown), the end of the slide bar 30 away from the driving device 10 is fixed to the door, and the sliding direction of the slide bar 30 is perpendicular to the plane where the door is located. Figure 2 The end of the slide bar 30 away from the driving device 10 is also provided with a fixing block 70, the fixing block 70 is fixedly connected to the slide bar 30, and the fixing block 70 is used to connect and fix the vehicle door and the slide bar 30. Figure 1 In the illustrated embodiment, the vehicle door further includes an inner guard plate, and the fixing block 70 is received in the inner guard plate, thereby ensuring that the fixing block 70 is fixedly connected to the vehicle door while increasing the simplicity and aesthetics of the vehicle of the present application.

[0098] Furthermore, in one embodiment, the length of the straight section 41 of the guide rail 40 in the door hinge assembly 100 is greater than the thickness of the door. It can be understood that in this embodiment, the length of the straight section 41 of the guide rail 40 in the door hinge assembly 100 defines the distance that the door is pushed away from the vehicle body. Setting the length of the straight section 41 greater than the thickness of the door can ensure that the door is reliably pushed away from the vehicle body and obtains sufficient rotation space.

[0099] It should be noted that the vehicle door hinge assembly 100 of the present application can adjust the target trajectory of the guide rail 40 by adjusting the length of the straight section 41 in the guide rail 40, the length of the spiral section 42 and / or the axial rotation angle of the spiral section 42, thereby adjusting the motion trajectory of the slide bar 30. That is, the present application can adapt to vehicle doors of different specifications by adjusting the length of the straight section 41 in the guide rail 40, the length of the spiral section 42 and / or the axial rotation angle of the spiral section 42, thereby improving the universality of the vehicle door hinge assembly 100 of the present application.
