[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of the template herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0037] like Figure 1 As shown, some embodiments of the utility model provide a door handle, which is applied to a vehicle to prevent the hidden door handle from freezing and becoming unable to be opened in cold weather, thereby ensuring that the door handle can be used normally in icy and snowy weather and improving the user experience.

[0038] The door handle includes a base 100 , a handle 200 , and a ventilation duct 300 .

[0039] The base 100 defines a mounting groove 110, and the mounting groove 110 can accommodate the handle 200. Specifically, the handle 200 is movably connected to the base 100. It should be noted that the connection between the handle 200 and the base 100 includes at least one of elastic connection, rotation connection, sliding connection, and telescopic connection, which can be specifically set according to actual conditions.

[0040] The handle 200 covers the notch of the installation groove 110 to seal the notch of the installation groove 110 , and there is a gap or mutual contact between the edge of the handle 200 and the edge of the inner wall of the notch of the installation groove 110 , which can be specifically set according to actual conditions.

[0041] Specifically, along the notch direction of the mounting groove 110, there is a gap between the edge of the handle 200 and the notch of the mounting groove 110, so that the handle 200 can be accommodated in the mounting groove 110, that is, when the handle 200 is moving, one end of the handle 200 can be accommodated in the mounting groove 110, and the other end of the handle 200 can pop out from the outside of the mounting groove 110.

[0042] In this embodiment, the handle 200 is telescopically connected to the base 100 .

[0043] In addition, the ventilation duct 300 is arranged between the handle 200 and the base 100. It can be understood that the ventilation duct 300 is arranged in the mounting groove 110, and a plurality of spaced ventilation holes 310 are opened on the ventilation duct 300. The ventilation duct 300 is connected to the thermal fluid generating device 400 of the vehicle to adjust the temperature of the fluid entering the ventilation duct 300 through the fluid generating device.

[0044] It can be understood that by increasing the temperature of the hot fluid entering the ventilation duct 300, the temperature of the hot fluid entering the mounting groove 110 through the ventilation hole 310 can be increased, thereby quickly increasing the temperature of the air in the mounting groove 110. As the air temperature in the mounting groove 110 increases, the temperature of the handle 200 and the base 100 can be quickly increased by heat conduction, thereby quickly melting the ice on the handle 200 so that the user can open the handle 200. In addition, it should be noted that since the fluid entering the ventilation duct 300 enters the mounting groove 110 through the ventilation hole 310, the air pressure entering the mounting groove 110 increases, and the hot fluid in the mounting groove 110 tends to be discharged to the gap between the handle 200 and the base 100, and forms air pressure on the ice layer condensed between the handle 200 and the base 100. That is to say, at this time, the air pressure in the mounting groove 110 is greater than the air pressure on the side of the handle 200 away from the mounting groove 110. At the same time, the hot fluid in the mounting groove 110 can contact the ice condensed on the handle 200 through the gap between the handle 200 and the base 100, that is, the hot fluid in the mounting groove 110 can directly contact the ice on the handle 200 to further improve the melting efficiency of the ice on the handle 200.

[0045] Specifically, when the door handle provided by the present application is applied to a vehicle, the thermal fluid generating device 400 is connected to the controller 500 of the vehicle, and the controller 500 controls the start or stop of the thermal fluid generating device 400. When the thermal fluid generating device 400 of the vehicle generates thermal fluid during operation, the thermal fluid flows through the ventilation duct 300 and enters the mounting groove 110 through the ventilation holes 310 on the ventilation duct 300, thereby forming a thermal fluid circulation in the mounting groove 110. The thermal fluid entering the mounting groove 110 heats the air in the mounting groove 110, which not only increases the temperature in the mounting groove 110, but also ensures the uniformity of the temperature change in each area of ​​the mounting groove 110. It can be understood that due to the increase in the temperature of the air in the mounting groove 110, the temperature around the handle 200 and the inner wall of the mounting groove 110 can be uniformly increased, so that the ice condensed around the handle 200 can be melted, effectively avoiding the situation of uneven local heating during the heating process, thereby ensuring that the handle 200 can be used normally and improving the user's experience.

[0046] The hot fluid described in this embodiment is hot air.

[0047] It should be noted that, in this embodiment, the vehicle's thermal fluid generating device 400 can not only adjust the temperature of the thermal fluid entering the ventilation duct 300, but also adjust the flow rate of the thermal fluid flowing through the ventilation duct 300, thereby quickly adjusting the temperature inside the handle 200, the base 100 and the installation groove 110, thereby increasing the melting speed of the ice condensed on the handle 200 and further improving the user experience.

[0048] In addition, by regulating the temperature inside the handle 200, the base 100 and the mounting groove 110 with the thermal fluid, the thermal fluid can circulate in the mounting groove 110, which can not only improve the uniformity of the temperature regulation inside the handle 200, the base 100 and the mounting groove 110, thereby improving the uniformity of melting the ice around the handle 200, but also increase the air pressure in the mounting groove 110, so that the hot air flow in the mounting groove 110 has air pressure on the ice around the handle 200, so as to increase the contact area between the thermal fluid in the mounting groove 110 and the ice on the handle 200, and has a thrust effect on the ice on the handle 200, so that the ice on the handle 200 tends to fall off the handle 200, so as to further improve the melting efficiency of the ice on the handle 200 and improve the efficiency of the ice on the handle 200 falling off the handle 200.

[0049] Specifically, when the weather temperature is less than or equal to zero degrees, a layer of ice may form on the surface of the door handle 200, or even on the surface of the vehicle door. When the thermal fluid generating device 400 in the vehicle is working, the temperature of the air in the mounting groove 110 can be increased by the action of the thermal fluid. At the same time, a part of the thermal fluid can pass through the gap between the handle 200 and the base 100 and contact the ice on the surface of the handle 200 corresponding to the gap between the handle 200 and the base 100, thereby quickly separating the handle 200 from the base 100. The ice in the gap between the handle 200 and the base 100 melts. At this time, the hot fluid in the mounting groove 110 can flow into the outside of the mounting groove 110 through the gap between the handle 200 and the base 100, and can come into contact with a portion of the ice on the surface of the handle 200 (it should be noted that there is a gap between this portion of ice and the handle 200, so that the hot fluid can flow through the gap between the handle 200 and the ice and come into contact with the ice, thereby quickly melting the ice on the surface of the handle 200), so as to further improve the melting efficiency of the ice on the surface of the handle 200.

[0050] like Figure 2As shown, in some embodiments of the present invention, the ventilation duct 300 is arranged in the mounting groove 110 along the edge of the groove, that is, the ventilation duct 300 is arranged along the inner wall of the mounting groove 110 to improve the coverage path of the ventilation duct 300 in the mounting groove 110, so as to further increase the amount of hot fluid flowing through the ventilation duct 300 and entering the mounting groove 110 per unit time, thereby improving the efficiency of heating the air temperature in the mounting groove 110 and the efficiency of heating the temperature of the handle 200 and the base 100.

[0051] The number of turns of the ventilation duct 300 in the installation groove 110 may be one turn, two turns or more turns, which can be specifically set according to actual conditions.

[0052] It should be noted that when the ventilation duct 300 is wound around the mounting groove 110 for one circle, the plane where the axis of the ventilation duct 300 is located is parallel to the plane where the bottom of the mounting groove 110 is located. When the ventilation duct 300 is wound around the mounting groove 110 for two or more circles, the ventilation duct 300 is wound along the inner wall of the mounting groove 110 and forms a spiral duct in the mounting groove 110 to further increase the length of the ventilation duct 300 in the mounting groove 110, thereby further increasing the flow rate of the hot fluid entering the mounting groove 110 through the ventilation holes 310 of the ventilation duct 300 per unit time, so as to further improve the efficiency of regulating the air temperature in the mounting groove 110 and the temperature of the handle 200 and the base 100.

[0053] like Figure 2 and Figure 3 As shown, in some embodiments of the present invention, the ventilation duct 300 is arranged at the connection between the bottom of the mounting groove 110 and the side wall of the mounting groove 110, so that the coverage area of ​​the hot fluid discharged from the ventilation hole 310 in the mounting groove 110 can be increased, so that the hot fluid flowing through the ventilation hole 310 can quickly flow through the mounting groove 110 to form a heat flow circulation in the mounting groove 110, thereby quickly increasing the temperature of the air in the mounting groove 110 and the temperature of the handle 200 and the base 100, and improving the uniformity of the temperature change of the mounting groove 110, the handle 200 and the base 100, thereby improving the efficiency and uniformity of melting the ice layer on the surface of the handle 200 and the gap between the handle 200 and the base 100.

[0054] In other embodiments, the ventilation duct 300 is arranged on the side wall of the mounting groove 110, and the plane where the axis of the ventilation duct is located is perpendicular to the side wall of the mounting groove 110. By setting the ventilation duct 300 on the side wall of the mounting groove 110, the distance between the ventilation hole 310 in the ventilation duct 300 and the handle 200 is reduced, thereby reducing the distance between the ventilation hole 310 and the ice on the surface of the handle 200. In this way, the hot fluid flowing through the ventilation hole 310 can quickly contact the ice in the gap between the handle 200 and the base 100, thereby further improving the melting efficiency of the ice on the surface of the handle 200.

[0055] like Figure 1 , Figure 3 and Figure 6 As shown, in some embodiments of the present invention, a plurality of ventilation holes 310 are arranged along the axial direction of the ventilation duct 300, and the openings of the ventilation holes 310 are toward the notch of the mounting groove 110, so that the hot fluid flowing through the ventilation duct 300 can be discharged through the ventilation holes 310, and the gas discharged through the ventilation holes 310 can be directly directed toward the notch of the mounting groove 110, so that the hot fluid entering the mounting groove 110 can quickly flow to the gap between the handle 200 and the base 100, so that the hot fluid can quickly contact the ice on the handle 200, thereby improving the efficiency of melting the ice on the handle 200.

[0056] In this embodiment, a plurality of ventilation holes 310 are arranged equidistantly along the axial direction of the ventilation duct 300 to further improve the uniformity of melting ice in the gap between the handle 200 and the base 100, and to improve the uniformity of temperature regulation of each area in the mounting groove 110 as well as the uniformity of temperature regulation of the handle 200 and the base 100.

[0057] The spacing between two adjacent ventilation holes 310 can be specifically set according to actual conditions. It is understandable that by reducing the spacing between two adjacent ventilation holes 310, the number of ventilation holes 310 provided on the ventilation duct 300 is increased, thereby increasing the amount of hot fluid entering the mounting groove 110 through the ventilation holes 310 per unit time, thereby further improving the efficiency of regulating the air temperature in the mounting groove 110 and the efficiency of regulating the temperature of the handle 200 and the base 100, and improving the efficiency of melting ice on the surface of the handle 200.

[0058] In addition, it should be noted that the aperture of the ventilation hole 310 can be specifically set according to actual conditions and is not specifically limited in this application.

[0059] like Figure 2 and Figure 3As shown, in some embodiments of the present invention, a connecting member 600 is provided on the side wall of the mounting groove 110, so as to connect the ventilation duct 300 to the base 100 through the connecting member 600, so as to improve the stability of the ventilation duct 300 in the mounting groove 110, so as to improve the stability of the connection between the ventilation duct 300 and the base 100.

[0060] In this embodiment, the connection between the connector 600 and the ventilation duct 300 includes any one of clamping, bonding, and bolting. In addition, the connection between the connector 600 and the base 100 includes any one of clamping, bonding, bolting, threading, and integral molding.

[0061] The connecting member 600 may be any one of an adhesive layer, a slot, a connecting rib, a connecting frame, a limiting plate, and a connecting block, and may be specifically set according to actual conditions.

[0062] In addition, the number of the connecting members 600 can be one, two, or any number above two, and can be set according to actual conditions.

[0063] In some embodiments of the utility model, the connector 600 is a card slot, and the ventilation duct 300 is partially clamped in the card slot. It should be noted that in some embodiments, the connector 600 is installed at the connection between the side wall of the mounting groove 110 and the bottom wall of the mounting groove 110, and a card slot is defined on the side of the connector 600 facing the handle 200, and a part of the ventilation duct 300 is clamped in the card slot to form a clamping structure to improve the stability of the ventilation duct 300 in the mounting groove 110 and improve the stability of the connection between the ventilation duct 300 and the base 100. In addition, in some embodiments, a card slot is defined at the connection between the side wall of the mounting groove 110 and the bottom wall of the mounting groove 110, and the card part of the ventilation duct 300 is set in the card slot to improve the stability of the connection between the ventilation duct 300 and the base 100.

[0064] like Figure 2 and Figure 3 As shown, in some embodiments of the present invention, the connecting member 600 is a plurality of connecting ribs, and the number of the connecting ribs can be specifically set according to actual conditions.

[0065] The connecting ribs are arranged on the side walls of the installation groove 110 , and the connecting ribs abut against the ventilation duct 300 , so as to limit the ventilation duct 300 through the connecting ribs, thereby improving the stability of the ventilation duct 300 in the installation groove 110 .

[0066] Specifically, the plurality of connecting ribs are staggered with the ventilation holes 310 along the axis of the ventilation duct 300 , that is, there is a gap between the connecting ribs and the ventilation holes 310 to prevent the connecting ribs from blocking the ventilation holes 310 , thereby ensuring the stability of the exhaust flow of the ventilation holes 310 .

[0067] like Figure 2 and Figure 3 As shown, in some embodiments of the utility model, a guide channel 700 is defined between two adjacent connecting ribs, and one end of the guide channel 700 close to the ventilation duct 300 is connected to at least one of the ventilation holes 310, and the end of the guide channel 700 away from the ventilation duct 300 is adjacent to the edge of the notch of the mounting groove 110, so as to provide a guiding effect for the hot fluid discharged from the ventilation hole 310 through the guide channel 700, so that the hot air flow entering the mounting groove 110 can quickly flow to the gap between the handle 200 and the base 100, so that the hot air flow during installation can quickly melt the ice condensed in the gap between the handle 200 and the base 100, thereby improving the efficiency of melting ice on the handle 200.

[0068] Specifically, in this embodiment, the plane where the connecting rib is located is perpendicular to the plane where the handle 200 is located, that is, the axis of the guide channel 700 is perpendicular to the plane where the handle 200 is located, so that the guide channel 700 can guide the hot air flow discharged from the vent to the gap between the handle 200 and the base 100.

[0069] like Figure 1 As shown, in some embodiments of the present invention, a first temperature sensor 800 is provided between the handle 200 and the base 100, and the first temperature sensor 800 is arranged at the edge of the notch of the mounting groove 110 to detect the temperature of the edge of the handle 200 and the edge of the base 100 through the first temperature sensor 800.

[0070] Specifically, by connecting the first temperature sensor 800 to the controller 500 of the vehicle, and the controller 500 to the thermal fluid generating device 400, the controller 500 controls the start or stop of the thermal fluid generating device 400. The first temperature sensor 800 sends the detected temperature value to the controller 500 of the vehicle through a signal, and the controller 500 receives the temperature value signal, and compares the temperature value with the preset temperature value for judgment.

[0071] If the temperature value detected by the first temperature sensor 800 is greater than the preset temperature value, the controller 500 will not start, that is, the thermal fluid generating device 400 is in a closed state; if the temperature value detected by the first temperature sensor 800 is less than the preset temperature value, the thermal fluid generating device 400 is started by the controller 500, and the thermal fluid generated by the thermal fluid generating device 400 enters the ventilation duct 300 and enters the mounting groove 110 through the vent hole, thereby adjusting the temperature inside the mounting groove 110 and the temperature of the handle 200 and the base 100.

[0072] like Figure 1 and Figure 5 As shown, in some embodiments of the utility model, the handle 200 includes a pressure cover 1100, and the pressure cover 1100 defines an installation opening 1110, through which a clearance space is provided for the handle 200, so that the handle 200 can pass through the installation opening 1110 during the movement.

[0073] The pressure cover 1100 is disposed at the notch of the mounting groove 110 and connected to the base 100 .

[0074] It should be noted that the connection method between the pressure cover 1100 and the base 100 includes any one of bonding, bolt connection, clamping, and magnetic connection, which can be specifically set according to actual conditions.

[0075] In this embodiment, the gland 1100 is connected to the base 100 by snapping. Specifically, a plurality of spaced protrusions are provided on the edge of the gland 1100, and a plurality of spaced slots are provided on the side of the base 100 facing the handle 200, and the plurality of spaced slots surround the notch of the mounting slot 110, the number of protrusions is equal to the number of slots, and each protrusion is correspondingly snapped into a slot, so that the gland 1100 is connected to the base 100.

[0076] It is understandable that the gland 1100 is connected to the base 100 by snap-fitting to improve the efficiency of installation or removal between the gland 1100 and the base 100 , and at the same time, facilitate the maintenance or replacement of the gland 1100 .

[0077] like Figure 4 and Figure 5 As shown, some other embodiments of the present invention provide a vehicle door, comprising a vehicle door body 900 and the door handle described in any one of the above embodiments.

[0078] The door body 900 defines a mounting hole. It should be noted that the shape of the mounting hole is the same as that of the handle 200 , and the mounting hole can accommodate the handle 200 , and there is a gap between the side wall of the handle 200 and the hole wall of the mounting hole.

[0079] In addition, the door handle is arranged on the inner side of the door body 900, and the connection method between the door handle and the door body 900 includes any one of bolt connection, bonding, clamping or welding, which can be specifically set according to actual conditions.

[0080] Specifically, the side of the handle 200 facing the mounting hole is flush with the outer side of the door body 900 to form a hidden door handle on the door, which not only improves the aesthetics of the outer side of the door body 900, but also melts the ice between the hole wall of the mounting hole and the handle 200 through the hot fluid generating device, so that the handle 200 can be opened normally.

[0081] It should be noted that the vehicle door provided in this embodiment has the structure of the door handle described in any of the above embodiments, and the beneficial effects produced by the structure of the door handle are not described one by one here.

[0082] like Figure 1 and Figure 5 As shown, in some embodiments of the present invention, a buffer member 1200 is provided between the door body 900 and the handle 200 , and the buffer member 1200 is a through-ring structure, so that a buffer structure is formed between the handle 200 and the door body 900 through the buffer member 1200 .

[0083] Specifically, the buffer member 1200 is disposed between the pressure cover 1100 and the vehicle door body 900 . The pressure cover 1100 is provided with an annular groove on one side facing the vehicle door body 900 . The buffer member 1200 is clamped in the annular groove to improve the stability of the connection between the buffer member 1200 and the pressure cover 1100 .

[0084] In addition, the side of the buffer member 1200 facing the door body 900 protrudes from the annular groove, that is, the side of the buffer member 1200 facing the door body 900 abuts against the door body 900 to form a buffer structure between the door body 900 and the handle 200, so that when the door is opened or closed, collision or friction between the door body 900 and the handle 200 can be avoided, thereby improving the service life of the door body 900 and the handle 200.

[0085] It should be noted that the buffer member 1200 is made of a material having elasticity and buffering function, and can be specifically set according to actual conditions.

[0086] Other embodiments of the present invention provide a vehicle, comprising the door handle described in any one of the above embodiments or the vehicle door described in any one of the above embodiments.

[0087] The vehicle provided in the present application further includes a second temperature sensor 1000 for detecting the external temperature of the vehicle. The second temperature sensor 1000 is connected to the controller 500, and the controller 500 can be connected to a mobile terminal.

[0088] It can be understood that the user can issue control instructions to the controller 500 through the mobile terminal, and the controller 500 can issue control instructions to the thermal fluid generating device, and the thermal fluid generating device receives the control instructions issued by the controller 500, and controls the startup, shutdown, working time and temperature of the thermal fluid of the thermal fluid generating device through the controller 500.

[0089] It should be noted that a vehicle generally has more than two doors. It should be noted that in the vehicle provided in this embodiment, at least one door has a first temperature sensor 800 to detect the temperature around the door handle through the first temperature sensor 800.

[0090] For example, if the vehicle has two doors, the first temperature sensor 800 is disposed in the handle 200 of any one of the two doors, or the first temperature sensor 800 is disposed in the handles 200 of both doors.

[0091] For example, if the vehicle has four doors, the handle 200 of any one of the four doors is provided with a first temperature sensor 800, or the handles 200 of any two doors are provided with a first temperature sensor 800, or the handles 200 of any three doors are provided with a first temperature sensor 800, or the handles 200 of all four doors are provided with a first temperature sensor 800, which can be specifically set according to actual conditions.

[0092] Furthermore, because the user will open the door corresponding to the driving seat in general, based on this, in the present embodiment, the handle 200 of the door corresponding to the driving seat of the vehicle has a first temperature sensor 800 .

[0093] It should be noted that the vehicle provided in this embodiment has the structure of the door handle described in any of the above embodiments, and the beneficial effects produced by the structure of the door handle are not described one by one here.

[0094] In addition, the vehicle provided in this embodiment has the door structure described in any of the above embodiments, and the beneficial effects produced by the door structure are not described one by one here.

[0095] In some embodiments of the present invention, the vehicle control instructions at least include a vehicle unlocking instruction, a handle 200 unlocking instruction, and a thermal fluid generating device control instruction.

[0096] Specifically, the vehicle unlocking instruction includes at least one of the vehicle immediate unlocking instruction, the vehicle delayed unlocking instruction, and the vehicle unlocking instruction at a preset time. The handle 200 unlocking instruction includes at least one of the handle 200 immediate unlocking instruction, the handle 200 delayed unlocking instruction, and the handle 200 unlocking instruction at a preset time. The thermal fluid generating device control instruction includes at least one of the thermal fluid generating device immediate start instruction, the handle 200 delayed start instruction, and the handle 200 start instruction at a preset time. It is understandable that the user can make specific settings according to the actual situation to enhance the user experience.

[0097] It should be noted that since the controller 500 is connected to the mobile terminal, that is, the user can control the vehicle through the mobile terminal and send control instructions to the vehicle, for example, send a vehicle unlocking instruction, a handle 200 unlocking instruction or a thermal fluid generating device control instruction to the vehicle through the mobile terminal.

[0098] In this embodiment, the control instructions of the thermal fluid generating device also include thermal fluid temperature control instructions, working time instructions and working time period instructions of the thermal fluid generating device.

[0099] It should be noted that the thermal fluid temperature control instruction of the thermal fluid generating device means that the user sets the temperature range or temperature value on the mobile terminal, and the thermal fluid temperature of the thermal fluid generating device is the temperature range or temperature value set by the user on the mobile terminal.

[0100] Secondly, the working time instruction of the thermal fluid generating device means that the user sets the startup time of the thermal fluid generating device on the mobile terminal, so that the thermal fluid generating device is started within the set time. During this time period, the temperature of the thermal fluid is within the set temperature range.

[0101] In addition, the working time period instruction of the thermal fluid generating device means that the user sets the time interval for starting the thermal fluid generating device on the mobile terminal, and the thermal fluid generating device is started in the corresponding time interval.

[0102] It can be understood that, in this embodiment, the user can set the time period for starting the thermal fluid generating device and the temperature of the thermal fluid through the mobile terminal.

[0103] In some other embodiments of the utility model, if the user forgets to set the vehicle control command on the mobile terminal before driving, that is, when the user wants to open the car door, the car handle 200 is in an ice state. At this time, the user can increase the temperature of the hot fluid of the hot fluid generating device on the mobile terminal, and send a control command to the hot fluid generating device (specifically, here it means: the user sends a control command to the controller 500 through the mobile terminal, and the controller 500 sends the received control command to the hot fluid generating device, and the hot fluid generating device starts), so that the temperature of the hot fluid generated by the hot fluid generating device rises quickly, generates a large amount of heat, and makes the ice around the handle 200 melt quickly, so that the user can quickly open the handle 200, improving the user experience.

[0104] In addition, the user can also send control instructions to the thermal fluid generating device through the mobile terminal so that the thermal fluid generating device is started in a preset time period, and by adjusting the thermal fluid temperature of the thermal fluid generating device, the handle 200 can maintain the set temperature in the preset time period, so as to improve the cold touch of the car handle 200 in a low temperature environment, so as to further enhance the user experience.

[0105] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limiting, and thus other examples of the exemplary embodiments may have different values.

[0106] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0107] The above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
