Description

Technical Field

[0001] The present application relates to the field of batteries, and in particular to a battery box, a battery, and a vehicle. Background Art

[0002] Battery packs, which provide the energy needed to propel the vehicle, hold a special place in new energy electric vehicles. They are typically composed of multiple battery cells (battery cells) arranged in modules, which are then housed within a battery case to form the entire battery pack. The battery pack's energy density, safety, and lifespan are key factors in determining electric vehicle performance.

[0003] During battery pack assembly, structural adhesives are often used to enhance the connection strength and sealing between components. However, the fluidity of the structural adhesive before curing on both sides of the module can lead to uneven distribution, which not only affects the connection effect but also weakens the overall structural strength of the battery pack. In large battery packs, inappropriate use of structural adhesives can pose serious safety hazards. Therefore, it is important to design a device that can effectively limit the flow of structural adhesive on both sides of the battery pack module and enhance the overall structural strength of the battery pack. Summary of the Invention

[0004] The purpose of this application is to provide a battery box, a battery and a vehicle.

[0005] According to a first aspect of an embodiment of the present application, a battery case is provided, comprising:

[0006] A main housing, the main housing including an installation space for installing a battery cell;

[0007] a blocking portion, the blocking portion being spaced apart from the installation space and comprising a first blocking unit and a second blocking unit, the first blocking unit being connected to the main housing, an end of the first blocking unit facing away from the main housing being rotatably connected to the second blocking unit, and the second blocking unit being rotatably disposed toward the installation space;

[0008] A pushing portion is connected to a side of the second blocking unit close to the installation space and is used to turn the second blocking unit toward the installation space.

[0009] It should be noted that on the one hand, the pushing part here can be such that the battery cell squeezes the structural adhesive so that it enters the pushing part, and then the pushing part pushes the second blocking unit to turn into the installation space and then abuts against the side of the battery cell. It can also be that the pushing part is used alone to make the second blocking unit abut against the side of the battery cell. For example, the pushing part itself has a trigger, and when the battery cell enters the installation space, it triggers the pushing of the second blocking unit. As long as the second blocking unit is turned into the installation space from the outside, it is within the protection scope of this application. The blocking part can be a baffle, a cover plate, etc., and its material can be metal or plastic. The first blocking unit and the second blocking unit are rotatably connected. On the one hand, it can be a shaft connection between the two, and on the other hand, it can also be a hinge connection. Of course, the first blocking unit and the second blocking unit can also have other connection methods. As long as they are rotatably connected to each other, it is within the protection scope of this application.

[0010] Based on the above settings, when the battery cell is installed into the installation space, the pushing part pushes the second blocking unit, so that the second blocking unit fits against the outside of the battery cell, and then a sealed space is formed between the blocking part and the battery cell. The structural adhesive between the battery cell and the battery box body is squeezed out from the side when the battery cell is installed. At this time, the first blocking unit of the blocking part first blocks the structural adhesive to prevent it from flowing out from the side and restricts it to flow only in the vertical direction. When the structural adhesive flows to the top, the second blocking unit blocks the overflow of the structural adhesive above. That is, the structural adhesive is restricted in this sealed space. Therefore, it is avoided that the structural adhesive flows to other positions, and thus the inside of the box body is kept clean. In addition, due to the shielding of the blocking part, the glue will slowly flow back at this time, making the distribution of the structural adhesive at the bottom of the box body uniform, and thus enhancing the connection strength and sealing performance of each component. And after the structural adhesive solidifies, it can directly fix the first blocking unit and the second blocking unit included in the blocking part and the battery cell together, so that the blocking part surrounds the battery cell and forms a side protection for the battery cell.

[0011] In some embodiments, the pushing part includes a hose unit. One end of the hose unit is connected to the second blocking unit, and the other end of the hose unit is communicated with the installation space.

[0012] Based on the above settings, since the hose unit is communicated with the installation space, when the battery cell is pressed down, the structural adhesive will enter the hose unit and push the second blocking unit connected to the hose unit to rotate. The above process does not require the intervention of other devices or manual work, and only relies on the falling of the battery cell to complete the rotation of the second blocking unit, thereby improving the installation efficiency.

[0013] In some embodiments, the pushing portion includes a connecting unit which penetrates through the first blocking unit. One end of the connecting unit is connected to the hose unit, and the other end of the connecting unit communicates with the installation space. The connecting unit is used to connect the installation space and the hose unit.

[0014] Based on the above settings, when the battery cell descends, part of the structural adhesive will be pressed into the connecting unit, and the air pressure in the hose unit will increase, causing it to extend outwards. Finally, the second blocking unit connected to the hose unit is pushed to rotate.

[0015] In some embodiments, the battery box body further includes a supporting portion which is arranged at one end of the first blocking unit facing away from the installation space. The supporting portion is used to support the second blocking unit, and the included angle between the second blocking unit and the first blocking unit is greater than or equal to 90° and less than or equal to 175°.

[0016] Based on the above settings, on the one hand, the supporting portion is arranged on the first blocking unit, which can ensure the integrity of the structure. Compared with being connected to the main housing, it requires less material and is more reasonably arranged. On the other hand, when the included angle between the second blocking unit and the first blocking unit is set to be greater than or equal to 90° and less than or equal to 175°, only a small amount of power from the pushing portion is required to make the second blocking unit flip. In addition, within this angle range, the second blocking unit will not flip due to installation vibration. For example, the included angle between the second blocking unit and the first blocking unit can be set to 90°, 100°, 110°, 120°, 130°, 140°, 150°, 160°, 170°, 175°.

[0017] In some embodiments, the supporting portion is arranged at one end of the first blocking unit close to the second blocking unit. The first blocking unit extends towards the side away from the installation space, and the included angle between the first blocking unit and the supporting portion is greater than or equal to 90° and less than 175°.

[0018] Based on the above settings, the end of the first blocking unit close to the second blocking unit is the closest end to the second blocking unit. The supporting portion extending outwards at this end can minimize the material used and can be more closely arranged with the second blocking unit to ensure a better supporting effect.

[0019] In some embodiments, there is an accommodating space between the first blocking unit and the installation space. The battery box body includes a guiding portion which is connected to the first blocking unit and is arranged in the accommodating space. The guiding portion is used to guide the battery cell to move towards the installation space.

[0020] Based on the above settings, the battery cell can be guided by the guiding part into a predetermined position, so that the battery cell can better cooperate with the battery box body, making the volumes reserved for the structural adhesive on both sides approach the same, and enhancing the tightness.

[0021] In some embodiments, the height of the guiding part gradually decreases from the first blocking unit towards the installation space, and the height of the guiding part at one end close to the installation space is greater than 0 cm.

[0022] Specifically, the height of the guiding part at one end close to the installation space can be 1 cm, 2 cm, 5 cm, 10 cm, 15 cm, 20 cm, 30 cm.

[0023] Based on the above settings, that is, a step is formed at one end of the installation space. When the battery cell slides below the step, it will be limited by the steps on both sides, thus further avoiding the offset of the battery cell and the installation space.

[0024] In some embodiments, the first blocking unit and the second blocking unit are connected by a rotating shaft, and the second blocking unit is arranged to be rotatable along the rotating shaft.

[0025] Through the rotating shaft, the second blocking unit can be dragged and rotated by the pushing part, and since the rotating shaft is respectively connected to the first blocking unit and the second blocking unit, the connection between the first blocking unit and the second blocking unit can be further ensured.

[0026] In some embodiments, the height of the blocking part in the vertical direction is greater than or equal to 1 cm and less than or equal to 50 cm.

[0027] With such settings, on the one hand, it can prevent waste of the material of the blocking part, and on the other hand, it can make the second blocking unit and the battery cell completely fixed to each other. For example, the height of the blocking part in the vertical direction can be set to 1 cm, 2 cm, 3 cm, 4 cm, 5 cm, 6 cm, 7 cm, 8 cm, 9 cm, 10 cm, 15 cm, 20 cm, 30 cm, 40 cm, 50 cm.

[0028] In some embodiments, the blocking part further includes a shielding unit, and the shielding unit is arranged at the connection between the first blocking unit and the second blocking unit to make the connection closed.

[0029] Based on the above settings, the shielding unit closes the connection between the first blocking unit and the second blocking unit, thereby avoiding the overflow of the structural adhesive from the connection between the first blocking unit and the second blocking unit, further ensuring the tightness of the structure and the cleanliness of the box body.

[0030] In some embodiments, the shielding unit can be compressively arranged. When the second blocking unit is located at one end away from the installation space, the shielding unit is compressively arranged; when the second blocking unit is located at one end close to the installation space, the shielding unit is stretched.

[0031] Based on the above arrangement, damage to the shielding unit can be avoided, and thus the connection structure between the first blocking unit and the second blocking unit can be better adapted, making it more durable, and further increasing the overall service life and durability of the battery box.

[0032] According to the second aspect of the embodiments of the present application, a battery is provided, and the battery includes the battery box according to any one of the above embodiments.

[0033] According to the third aspect of the embodiments of the present application, a vehicle is provided, and the vehicle includes the battery according to the above embodiments.

[0034] The beneficial technical effects brought by the technical solutions provided by the embodiments of the present application are:

[0035] By providing a main housing, a blocking portion, and a pushing portion. Among them, the main housing includes an installation space, the blocking portion includes a first blocking unit and a second blocking unit, the first blocking unit is connected to the main housing, one end of the first blocking unit away from the main housing is rotatably connected to the second blocking unit, and the second blocking unit can be rotatably arranged towards the installation space, and the pushing portion is connected to the side of the second blocking unit away from the installation space for turning the second blocking unit towards the installation space.

[0036] Based on the above arrangement, when the battery cell is installed into the installation space, the pushing portion pushes the second blocking unit, so that the second blocking unit fits against the outside of the battery cell, and thus a sealed space is formed between the blocking portion and the battery cell. The structural adhesive between the battery cell and the battery box is extruded and overflows from the side during the installation of the battery cell. At this time, the first blocking unit of the blocking portion first blocks the structural adhesive to prevent it from flowing out from the side and restricts it to flow only in the vertical direction. When the structural adhesive flows to the top, the second blocking unit blocks the overflow of the structural adhesive above. That is, the structural adhesive is restricted in this sealed space. Therefore, it is avoided that the structural adhesive flows to other positions, and thus the cleanliness inside the box is maintained. In addition, due to the shielding of the blocking portion, the glue will slowly flow back at this time, making the distribution of the structural adhesive at the bottom of the box uniform, and further enhancing the connection strength and sealing performance of each component.

[0057] Here, in conjunction with the accompanying drawings, the technical solutions in the embodiments (or "embodiments") of the present application will be clearly and completely described. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numerals in different drawings represent the same or similar elements.

[0058] If there are terms related to directional indications or positional relationships in the embodiments of the present application (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and motion conditions between components in a specific posture (as shown in the accompanying drawings); if this specific posture changes, then the directional indication or positional relationship also changes accordingly. In addition, terms such as "first" and "second" in the embodiments of the present application are only for the purpose of convenient description and cannot be construed as indicating or implying relative importance.

[0059] New energy vehicles mainly consist of components such as a battery pack, an electric motor, a power electronics controller, an on-board charger, a thermal management system, and an intelligent control system.

[0060] Among them, the battery pack provides the energy required to drive the vehicle. It is usually composed of multiple battery cells (cores) into modules, and then these core modules are arranged in a battery box to form the entire battery pack. The energy density, safety, and lifespan of the battery pack are the key factors determining the performance of electric vehicles. The electric motor is used to convert the electrical energy provided by the battery into mechanical energy, thereby driving the wheels to rotate. Depending on the design, types such as AC asynchronous motors or permanent magnet synchronous motors can be used. The selection of the electric motor affects the acceleration performance and top speed of the vehicle. The power electronics controller includes components such as an inverter and a converter, and is responsible for regulating the current and voltage output by the battery to meet the requirements of the electric motor. In addition, it also manages the regenerative energy recovery process during braking, converting part of the kinetic energy into electrical energy and charging it back into the battery. The on-board charger is used to convert external power (such as alternating current provided by a household socket or a public charging pile) into direct current to charge the battery. Its efficiency and power level directly affect the charging speed. The thermal management system is used to ensure that the battery, electric motor, and power electronic components operate within an appropriate working temperature range, avoiding efficiency degradation or damage caused by overheating. This usually involves a coolant circulation system or an air cooling system. The intelligent control system integrates multiple sensors and software algorithms, and monitors and adjusts the states of the above-mentioned systems in real time to ensure the safe, stable, and efficient operation of the vehicle. For example, by monitoring the state of the battery to optimize the charging strategy, or dynamically adjusting the output power of the electric motor according to driving conditions.

[0061] The relationships among the above parts are closely interconnected. The battery pack supplies power to the electric motor and other electrical systems. The electric motor directly drives the vehicle forward and collaborates with the power electronics controller to achieve precise speed control and energy recovery. The on-board charger allows the vehicle to obtain energy from the power grid to replenish the battery. The thermal management system protects key components from extreme temperatures and ensures the normal operation of the entire system. The intelligent control system coordinates the work of all components, improving the user experience while ensuring driving safety.

[0062] The battery pack mentioned above is the heart of electric vehicles and has a special status in new energy electric vehicles. During the battery pack assembly process, when the battery cells are arranged in the battery box, structural adhesive is often used to enhance the connection strength and sealing between the components. However, the fluidity of the structural adhesive before curing on both sides of the module may cause its uneven distribution, which not only affects the connection effect, but also may weaken the overall structural strength of the battery pack. Especially in large battery packs, improper use of structural adhesive may cause serious safety hazards, which in turn puts the entire vehicle at safety risk. Therefore, it is of great significance to design a device that can effectively limit the flow of structural adhesive on both sides of the battery pack module and improve the overall structural strength of the battery pack.

[0063] The present application provides a battery, which includes a battery cell 20 and a battery box 10, wherein the battery cell 20 is arranged in an installation space 110 of the battery box 10. The battery is used in a vehicle and provides energy to the vehicle to drive the vehicle.

[0064] refer to Figures 1 - 6 As shown, Figures 1 - 3 The battery box 10 is not matched with the battery cell 20. Figures 4 - 6 The battery case 10 and the battery cell 20 are in a mating state. The battery case 10 includes a main housing 100, a blocking portion 200, and a pushing portion 300. The main housing 100 includes an installation space 110 for installing the battery cell 20. The blocking portion 200 is spaced apart from the installation space 110 and includes a first blocking unit 210 and a second blocking unit 220. The first blocking unit 210 is connected to the main housing 100, and the end of the first blocking unit 210 facing away from the main housing 100 is rotatably connected to the second blocking unit 220. The second blocking unit 220 can be rotatably arranged toward the installation space 110. The pushing portion 300 is connected to the side of the second blocking unit 220 facing away from the installation space 110 and is used to turn the second blocking unit 220 toward the installation space 110.

[0065] It should be noted that on the one hand, the pushing part 300 here can be such that the battery cell 20 squeezes the structural adhesive, causing it to enter the pushing part 300, and then the pushing part 300 pushes the second blocking unit 220 to turn into the installation space 110 and then abuts against the side of the battery cell 20. It can also be that the pushing part 300 is used alone to make the second blocking unit 220 abut against the side of the battery cell 20. For example, the pushing part 300 itself has a trigger, and when the battery cell 20 enters the installation space 110, it triggers the pushing of the second blocking unit 220. As long as the second blocking unit 220 is turned into the installation space 110 from the outside, it is within the protection scope of this application. The blocking part 200 can be a baffle, a cover plate, etc., and its material can be metal or plastic. The first blocking unit 210 and the second blocking unit 220 are rotatably connected. On the one hand, it can be a shaft connection between the two, and on the other hand, it can also be a hinge connection. Of course, the first blocking unit 210 and the second blocking unit 220 can also have other connection methods. As long as they are rotatably connected to each other, it is within the protection scope of this application.

[0066] Based on the above settings, when the battery cell 20 is installed into the installation space 110, the pushing part 300 pushes the second blocking unit 220, so that the second blocking unit 220 fits against the outside of the battery cell 20, and then a sealed space is formed between the blocking part 200 and the battery cell 20. The structural adhesive between the battery cell 20 and the battery box 10 is squeezed out from the side when the battery cell 20 is installed. At this time, the first blocking unit 210 of the blocking part 200 first blocks the structural adhesive to prevent it from flowing out from the side and restricts it to flow only in the vertical direction. When the structural adhesive flows to the top, the second blocking unit 220 blocks the overflow of the structural adhesive above. That is, the structural adhesive is restricted in this sealed space. Therefore, it is avoided that the structural adhesive flows to other positions, and thus the interior of the box is kept clean. In addition, due to the shielding of the blocking part 200, the glue will slowly flow back at this time, making the distribution of the structural adhesive at the bottom of the box uniform, and then enhancing the connection strength and sealing performance of each component. And after the structural adhesive solidifies, it can directly fix the first blocking unit 210 and the second blocking unit 220 included in the blocking part 200 and the battery cell 20 together, so that the blocking part 200 surrounds the battery cell 20 and forms a lateral protection for the battery cell 20.

[0067] In one embodiment, refer to Figure 2 , Figure 3 and Figure 5As shown, the pushing portion 300 includes a hose unit 310. One end of the hose unit 310 is connected to the second blocking unit 220, and the other end of the hose unit 310 is connected to the installation space 110. It should be noted that the connection between the hose unit 310 and the installation space 110 can include both the hose unit 310 passing through the pushing portion 300 and the installation space 110, and the hose unit 310 connecting to the installation space 110 from below the pushing portion 300.

[0068] Based on this arrangement, since the hose unit 310 is connected to the installation space 110, when the battery cell 20 is pressed downward, the structural adhesive enters the hose unit 310 and rotates the second blocking unit 220 connected to the hose unit 310. This process does not require any other devices or human intervention; the second blocking unit 220 rotates solely through the falling of the battery cell 20, thereby improving installation efficiency.

[0069] In one embodiment, continue to refer to Figure 2 、 Figure 3 as well as Figure 5 As shown, the pusher 300 includes a connecting unit 320, which is disposed through the first blocking unit 210. One end of the connecting unit 320 is connected to the hose unit 310, and the other end of the connecting unit 320 is connected to the installation space 110. The connecting unit 320 is used to connect the installation space 110 and the hose unit 310. It should be noted that the connecting unit 320 and the first blocking unit 210 are fixed to each other and sealed to prevent the structural adhesive from escaping from the gap between the connecting unit 320 and the first blocking unit 210. In addition, the pipe of the connecting unit 320 disposed in the installation space 110 can be made of a soft material to prevent damage by the battery cells 20.

[0070] Based on the above arrangement, when the battery cell 20 descends, part of the structural adhesive will be pressed into the connecting unit 320, and the air pressure in the hose unit 310 will increase, thereby extending outward, and finally pushing the second blocking unit 220 connected to the hose unit 310 to rotate.

[0071] In one embodiment, the battery case further includes a support portion (not shown in the figure), which is arranged at one end of the first blocking unit 210 away from the installation space 110, and the support portion is used to support the second blocking unit 220, and the angle between the second blocking unit 220 and the first blocking unit 210 is greater than or equal to 90° and less than 175°.

[0072] Based on the above arrangement, on the one hand, the support portion is disposed on the first blocking unit 210, which ensures structural integrity. Compared to a connection to the main housing 100, it requires less material and is more rationally configured. On the other hand, when the angle between the second blocking unit 220 and the first blocking unit 210 is set to be greater than or equal to 90° and less than or equal to 175°, only a small amount of force is required from the pusher 300 to flip the second blocking unit 220. Furthermore, within this angle range, the second blocking unit 220 will not flip due to vibration from the installation. For example, the angle between the second blocking unit 220 and the first blocking unit 210 can be set to 90°, 100°, 110°, 120°, 130°, 140°, 150°, 160°, 170°, or 175°.

[0073] In one embodiment, the support portion is disposed at one end of the first blocking unit 210 close to the second blocking unit 220, and the first blocking unit 210 extends toward a side away from the installation space 110, and the angle between the first blocking unit 210 and the support portion is greater than or equal to 90° and less than 175°.

[0074] Based on the above settings, refer to Figure 2 and Figure 3 It can be seen that the end of the first blocking unit 210 close to the second blocking unit 220 is the end closest to the second blocking unit 220, and the support part extends outward at this end. On the one hand, the material that can be used is minimized, and on the other hand, it can be more closely fitted with the second blocking unit 220 to ensure better support.

[0075] Since the battery cell 20 will have a small deviation when falling, the battery cell 20 cannot fall completely into the installation space 110, which leads to different volumes of structural adhesive on both sides of the battery cell 20, further affecting the airtightness of the package and the force on both sides of the battery cell 20.

[0076] refer to Figures 1 - 6 As shown, a receiving space 120 is included between the first blocking unit 210 and the installation space 110, and the battery box 10 is provided with a guide portion 400, which is connected to the first blocking unit 210 and is arranged in the receiving space 120. The guide portion 400 is used to guide the battery cell 20 to move to the installation space 110.

[0077] Based on the above arrangement, the battery cell 20 can enter a predetermined position under the guidance of the guide portion 400 , thereby enabling the battery cell 20 to better cooperate with the battery case 10 , so that the volumes reserved for the structural adhesive on both sides are close to the same, thereby enhancing the airtightness.

[0078] In one embodiment, the guiding portion 400 is arranged such that its height gradually decreases from the first blocking unit 210 towards the installation space 110, and the height of the guiding portion 400 at the end close to the installation space 110 is greater than 0 cm. Specifically, the height of the guiding portion 400 at the end close to the installation space 110 can be 1 cm, 2 cm, 5 cm, 10 cm, 15 cm, 20 cm, 30 cm.

[0079] Based on the above settings, that is, a step is formed at one end of the installation space 110. When the battery cell 20 slides below the step, it will be limited by the steps on both sides, thereby further preventing the offset between the battery cell 20 and the installation space 110.

[0080] The inventor found that when the height of the blocking portion 200 is too low, the structural adhesive easily flows outwards across the blocking portion 200, and thus fails to play a blocking role. At the same time, when the height of the blocking portion 200 is too high, on the one hand, it will cause waste of the material of the blocking portion 200, and on the other hand, it will cause the second blocking unit 220 to be unable to contact the structural adhesive, thereby resulting in the second blocking unit 220 and the battery cell 20 not being fully fixed to each other.

[0081] In the present application, the height of the blocking portion 200 in the vertical direction is set to be greater than or equal to 1 cm and less than or equal to 50 cm. With such a setting, on the one hand, it can prevent waste of the material of the blocking portion 200, and on the other hand, it can enable the second blocking unit 220 and the battery cell 20 to be fully fixed to each other. For example, the height of the blocking portion 200 in the vertical direction can be set to 1 cm, 2 cm, 3 cm, 4 cm, 5 cm, 6 cm, 7 cm, 8 cm, 9 cm, 10 cm, 15 cm, 20 cm, 30 cm, 40 cm, 50 cm.

[0082] Since the first blocking unit 210 and the second blocking unit 220 are pivotally connected, there will be some gaps between them, and the structural adhesive will overflow outwards from these gaps. Especially during the rotation of the second blocking unit 220, the structural adhesive will be more likely to overflow outwards from these gaps.

[0083] In one embodiment, the blocking portion 200 further includes a shielding unit (not shown in the figure). The shielding unit is arranged at the connection between the first blocking unit 210 and the second blocking unit 220 to make the connection closed. It should be noted that the shielding unit here can be made of elastic plastics, rubbers, etc., as long as it can rotate with the second blocking unit 220 and form a sealed space so that the structural adhesive will not overflow, that is, it is within the scope of protection required by the present application.

[0084] Based on the above settings, the shielding unit seals the connection between the first blocking unit 210 and the second blocking unit 220, thereby preventing the structural adhesive from overflowing from the connection between the first blocking unit 210 and the second blocking unit 220, further ensuring the sealing performance of the structure and keeping the box body clean.

[0085] Furthermore, in one embodiment, the shielding unit can be compressively arranged. When the second blocking unit 220 is located at the end away from the installation space 110, the shielding unit is compressively arranged; when the second blocking unit 220 is located at the end close to the installation space 110, the shielding unit is stretched.

[0086] Based on the above settings, damage to the shielding unit can be avoided, and thus the connection structure between the first blocking unit 210 and the second blocking unit 220 can be better adapted, making it more durable, and further increasing the overall lifespan and durability of the battery box body 10.

[0087] It should be noted that the technical solutions or technical features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the drawings; all modifications, equivalent replacements, improvements, etc. made within the spirit and principles of this application shall be included within the scope of protection of this application.
