Description

Technical Field

[0001] This invention relates to the field of vehicles, and more specifically to a spare tire mounting bracket and a vehicle. Background Technology

[0002] Because of its function of storing the spare tire, the spare tire well in a vehicle requires a greater stamping depth than regular sheet metal parts. Therefore, the sheet metal used for processing the spare tire well is generally thinner. However, in this case, stress concentration points are prone to cracking and deformation during stamping. Furthermore, the overall strength of the finished spare tire well structure is insufficient, making it susceptible to resonance, which increases interior noise and negatively impacts NVH performance. Additionally, lower sheet metal strength leads to reduced component durability.

[0003] To address the aforementioned issues, some existing spare tire storage solutions involve adding reinforcing components to the spare tire storage area or directly increasing the thickness of the sheet metal parts. However, this leads to increased component costs and vehicle weight, which is detrimental to achieving vehicle lightweighting and energy efficiency. Summary of the Invention

[0004] One objective of this invention is to provide a spare tire mounting bracket to solve problems such as easy cracking, resonance, noise, and reduced durability caused by the low structural strength of the spare tire well in the prior art. A second objective of this invention is to provide a vehicle including the aforementioned spare tire mounting bracket.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A spare tire mounting bracket has a spare tire pool formed thereon. The spare tire mounting bracket is provided with a plurality of main reinforcing ribs. Each main reinforcing rib includes two rib sections, each rib section extending from the edge of the spare tire pool towards the bottom center of the spare tire pool, and the two rib sections of each main reinforcing rib are connected at the bottom of the spare tire pool to form a connecting portion connecting the two rib sections. The rib sections and connecting portions of the plurality of main reinforcing ribs are spaced apart from each other.

[0007] In the above technical solution, the spare tire pool is provided with multiple main reinforcing ribs, each of which includes two rib sections. These two rib sections extend from the bottom center of the spare tire pool to the edge of the spare tire pool, and the two rib sections are connected at the bottom of the spare tire pool to form a connecting part. Based on the main reinforcing ribs of the above structure, the spare tire pool can achieve greater structural strength. While achieving greater structural strength, no other structural reinforcing ribs are needed, which can achieve weight reduction for the spare tire mounting bracket. Furthermore, when achieving greater structural strength, the depth of the rib sections of the main reinforcing ribs does not need to be set too large. This makes the process of forming the main reinforcing ribs by stamping or other methods less difficult, and reduces the risk of cracking in areas of stress concentration.

[0008] Furthermore, the included angle between the two rib portions of the plurality of main reinforcing ribs is the same.

[0009] In the above technical solution, when the included angle between the two rib sections of multiple main reinforcing ribs is the same, the multiple main reinforcing ribs are actually identical (for main reinforcing ribs belonging to the same first region or the same second region). This results in a more uniform stress distribution and structural strength across the spare tire mounting bracket. Moreover, when forming multiple main reinforcing ribs by means such as stamping, multiple stamping dies with different included angles are not required. With a single stamping die, multiple main reinforcing ribs can be formed sequentially by simply changing the position of the spare tire mounting bracket, without requiring any changes or adjustments to the die during the entire stamping process.

[0010] Furthermore, the multiple main reinforcing ribs are arranged symmetrically along an axis, and the axis of symmetry is consistent with the centerline of the vehicle in the longitudinal direction to which the spare tire mounting bracket is adapted.

[0011] In the above technical solution, after the spare tire mounting bracket is installed on the vehicle, the main reinforcing ribs on its left and right sides are symmetrical. This helps to ensure the structural stability and balance of the spare tire pool and helps to reduce the vibration of the spare tire pool during vehicle operation.

[0012] Furthermore, the spare tire mounting bracket is also provided with a first auxiliary reinforcing rib, which is disposed between the adjacent rib portions of two adjacent main reinforcing ribs and connects the two adjacent rib portions.

[0013] In the above technical solution, by setting the first auxiliary reinforcing rib, the structural strength of the spare tire pool between the adjacent main reinforcing ribs can be increased, and the overall structural strength of the spare tire pool can also be increased.

[0014] Furthermore, the spare tire mounting bracket is also provided with a second auxiliary reinforcing rib, which extends from the edge of the spare tire pool to the bottom center of the spare tire pool and connects with the rib portion of a main reinforcing rib.

[0015] In the above technical solution, the second auxiliary reinforcing rib can increase the structural strength of the area between the rib section it is connected to and the edge of the spare tire pool, and also increase the overall structural strength of the spare tire pool.

[0016] Furthermore, the spare tire mounting bracket is also provided with a third auxiliary reinforcing rib, which is located between the two main reinforcing ribs and extends from the edge of the spare tire pool towards the center.

[0017] In the above technical solution, the third auxiliary reinforcing rib can increase the structural strength of the spare tire pool in the area between the two main reinforcing ribs.

[0018] Furthermore, the connection portion of each of the main reinforcing ribs has a chamfered shape.

[0019] In the above technical solution, by setting a chamfer shape at the connection part, the structural strength of the bottom of the spare tire pool can be increased.

[0020] Furthermore, at least one end of the rib portion extends to the top of the spare tire pool, and a flat chamfered transition area is provided at the end of the top of the spare tire pool.

[0021] In the above technical solution, by providing a flat chamfered transition area at the end of the rib section that connects to the top of the spare tire tank, the structural strength at the connection point can be increased.

[0022] Furthermore, each of the main reinforcing ribs is provided with a leakage hole at its connection point.

[0023] In the above technical solution, by setting a leakage hole, the electrophoretic liquid and the like can flow along the groove formed by the main reinforcing rib during the coating process, and can better flow out of the spare tire pool from the leakage hole.

[0024] Furthermore, the bottom of the main reinforcing rib and the second auxiliary reinforcing rib are provided with a plurality of welding bolts, which are used for welding connection with the heat insulation plate.

[0025] In the above technical solution, by setting welding bolts, the heat insulation plate can be welded to the spare tire mounting bracket, and the welded heat insulation plate can protect the spare tire pool.

[0026] Furthermore, a strip-shaped protrusion is provided at the center of the bottom of the spare tire pool, and a spare tire mounting bracket is fixed on the protrusion.

[0027] In the above technical solution, the presence of a boss enhances the structural strength of the spare tire well bottom. Furthermore, fixing the spare tire mounting bracket to the boss increases the installation torque of the spare tire and improves the durability of loading and unloading it.

[0028] Furthermore, a fifth auxiliary reinforcing rib is provided on the boss.

[0029] In the above technical solution, a fifth auxiliary reinforcing rib is set on the boss to further enhance the structural strength of the bottom of the spare tire pool.

[0030] A vehicle that includes the aforementioned spare tire mounting hardware.

[0031] The beneficial effects of this invention are:

[0032] The spare tire mounting bracket and vehicle provided by this invention have multiple main reinforcing ribs in the spare tire well. Each main reinforcing rib includes two rib sections that extend from the bottom center of the spare tire well to its edge, and these two rib sections are connected at the bottom of the spare tire well to form a connecting portion. Based on the main reinforcing ribs of the above structure, the spare tire well can achieve greater structural strength. While achieving greater structural strength, no other structural reinforcements are needed, which allows for lightweighting of the spare tire mounting bracket. Furthermore, when achieving greater structural strength, the depth of the rib sections of the main reinforcing ribs does not need to be excessive, thus reducing the manufacturing difficulty when forming the main reinforcing ribs by stamping or other methods, and lowering the risk of cracking in areas of stress concentration.

[0047] The embodiments of the present invention will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.

[0048] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0049] In an embodiment of the spare tire mounting bracket of the present invention, such as Figures 1-3 As shown, a spare tire holder has a spare tire well formed on it. Specifically, the spare tire holder includes a flat portion 1 and a groove. The groove is formed by means of, for example, stamping. The groove serves as the spare tire well 2, which has a bottom 2a and a sidewall 2b. Multiple main reinforcing ribs 21 are provided on the spare tire holder, and these ribs are mainly formed within the spare tire well 21. Each main reinforcing rib 21 includes two rib portions 211. Each rib portion 211 extends from the edge of the spare tire well 2 (the outer end of the rib portion 211) towards the bottom center of the spare tire well 2 (the inner end of the rib portion 211). The two rib portions 211 of each main reinforcing rib 21 are connected at the bottom of the spare tire well 2, forming a connecting portion 212 that connects the two rib portions 211. The rib portions 211 and connecting portions 212 of the multiple main reinforcing ribs 21 are spaced apart from each other.

[0050] In the above embodiment, the rib portion 211 of the main reinforcing rib 21 extends from the edge of the spare tire pool 2 towards the bottom center of the spare tire pool 2. The edge of the spare tire pool 2 can be the top of the sidewall of the spare tire pool 2 or the bottom edge of the spare tire pool 2. It is understood that the actual position of the edge of the spare tire pool 2 is affected by the overall structure of the spare tire mounting bracket, such as... Figures 1-3In the structure of the spare tire holder shown, the spare tire pool sidewall 2b is not correspondingly provided in the entire circumferential area of ​​the spare tire pool 2. The spare tire pool 2 has a spare tire pool sidewall 2b in a certain circumferential area, which is called the first area, while the spare tire pool 2 does not have a spare tire pool sidewall 2b in another circumferential area, which is called the second area. That is, the spare tire pool 2 has a spare tire pool sidewall 2b in the first area, while in the other second area, the spare tire pool 2 is an open structure without a spare tire pool sidewall 2b (in this second area, the spare tire holder matches with other structures on the vehicle). In actual implementation, to achieve better results, in the first area, the outer end of each rib portion 211 extends to the top of the spare tire pool sidewall 2b, while in the second area, the outer end of each rib portion 211 extends to the edge of the spare tire pool bottom 2a. Furthermore, as Figures 1-3 As shown, the rib portion 211 extends toward the center of the spare tire pool bottom 2a, but the inner end of the rib portion 211 does not extend inward to the absolute center of the spare tire pool bottom 2a. Other structures, such as the boss 25 and spare tire mounting bracket 3 described later, are typically provided in the central region of the spare tire pool bottom 2a. The inner end of the rib portion 211 only extends to near the central region of the spare tire pool bottom 2a, while remaining spaced apart from other structures provided at the center of the spare tire pool bottom 2a.

[0051] In the above embodiments, the rib portions 211 and connecting portions 212 of the plurality of main reinforcing ribs 21 are spaced apart from each other. This means that there is a gap between the rib portion 211 of each main reinforcing rib 21 and the rib portion 211 and connecting portion 212 of another main reinforcing rib 21, and there is a gap between the connecting portion 212 of each main reinforcing rib 21 and the rib portion 211 and connecting portion 212 of another main reinforcing rib 21. In general, each main reinforcing rib 21 does not intersect with other main reinforcing ribs 21 (but two main reinforcing ribs 21 can be connected by another structure, such as a first auxiliary reinforcing rib 22, which will be described in detail later).

[0052] In this embodiment, a plurality of main reinforcing ribs 21 are provided in the spare tire pool 2. Each main reinforcing rib 21 includes two rib sections 211, which extend from the center of the bottom 2a of the spare tire pool to the edge of the spare tire pool 2, and the two rib sections 211 are connected at the bottom of the spare tire pool 2 to form a connecting part 212. Based on the main reinforcing ribs 21 of the above structure, the spare tire pool 2 can achieve greater structural strength. While achieving greater structural strength, the spare tire pool 2 does not need to use other structural reinforcements, and it can achieve lightweighting for the spare tire fixing frame. In addition, when the main reinforcing ribs 21 of the above structure achieve greater structural strength, the depth of the rib sections 211 of the main reinforcing ribs 21 does not need to be set too large. In this way, when forming the structure of the main reinforcing ribs 21 by means of stamping or other methods, the process difficulty is small, and the risk of cracking in the stress concentration area is low.

[0053] In one embodiment of the spare tire mounting bracket, the included angle between the two rib portions 211 of the plurality of main reinforcing ribs 21 is the same.

[0054] In this embodiment, when the included angle between the two rib portions 211 of the multiple main reinforcing ribs 21 is the same, the multiple main reinforcing ribs 21 are actually identical (for main reinforcing ribs 21 belonging to the same first region or the same second region). This makes the stress and structural strength of each region of the spare tire mounting bracket more uniform. Moreover, when the multiple main reinforcing ribs 21 are formed by means such as stamping, multiple stamping dies with different included angles are not required. With a single stamping die, the multiple main reinforcing ribs 21 can be formed sequentially by simply changing the position of the spare tire mounting bracket. No changes or adjustments to the die are required during the entire stamping process.

[0055] Specifically, the included angle between the two rib portions 211 of each main reinforcing rib 21 can be 45 degrees, 60 degrees, 90 degrees, 120 degrees, etc.

[0056] When the included angle between the two rib portions 211 of each main reinforcing rib 21 is 90 degrees, the spare tire mounting bracket can be provided with 4 main reinforcing ribs 21; when the included angle between the two rib portions 211 of each main reinforcing rib 21 is 120 degrees, the spare tire mounting bracket can be provided with 3 main reinforcing ribs 21; when the included angle between the two rib portions 211 of each main reinforcing rib 21 is 60 degrees, the spare tire mounting bracket can be provided with 6 main reinforcing ribs 21. In the above-mentioned cases, the two adjacent rib portions 211 of two adjacent main reinforcing ribs 21 can be parallel to each other.

[0057] Of course, the included angle between the two rib portions 211 of each main reinforcing rib 21 and the number of main reinforcing ribs 21 on the spare tire mounting bracket may not have the aforementioned correspondence. For example, when the included angle between the two rib portions 211 of each main reinforcing rib 21 is 90 degrees, the spare tire mounting bracket may have 2 or 3 main reinforcing ribs 21; when the included angle between the two rib portions 211 of each main reinforcing rib 21 is 120 degrees, the spare tire mounting bracket may have 2 or 4 main reinforcing ribs 21; when the included angle between the two rib portions 211 of each main reinforcing rib 21 is 60 degrees, the spare tire mounting bracket may have 3 or 4 main reinforcing ribs 21. In the above cases, the two adjacent rib portions 211 of two adjacent main reinforcing ribs 21 generally cannot be parallel.

[0058] In other embodiments of the present invention, the included angle between the two rib portions 211 of the plurality of main reinforcing ribs 21 may also be different. For example, in the case where there are four main reinforcing ribs 21 on the spare tire mounting bracket, the included angle between the two rib portions 211 of the first main reinforcing rib 21 is 90 degrees, the included angle between the two rib portions 211 of the second main reinforcing rib 21 may be 60 degrees, the included angle between the two rib portions 211 of the third main reinforcing rib 21 may be 60 degrees, and the included angle between the two rib portions 211 of the fourth main reinforcing rib 21 is 75 degrees.

[0059] In one embodiment of the spare tire mounting bracket, a plurality of main reinforcing ribs 21 are arranged symmetrically along an axis, and the axis of symmetry is consistent with the centerline of the vehicle to which the spare tire mounting bracket is adapted in the longitudinal direction.

[0060] In this embodiment, after the spare tire mounting bracket is installed on the vehicle, the main reinforcing ribs 21 on its left and right sides are symmetrical, which helps to ensure the structural stability and balance of the spare tire pool 2 and helps to reduce the vibration of the spare tire pool 2 during vehicle operation.

[0061] In one embodiment of the spare tire mounting bracket, the spare tire mounting bracket is further provided with a first auxiliary reinforcing rib 22, which is disposed between the adjacent rib portions 211 of two adjacent main reinforcing ribs 21, and connects the two adjacent rib portions 211.

[0062] In this embodiment, by setting the first auxiliary reinforcing rib 22, the structural strength of the spare tire pool 2 between the rib portions 211 of the two adjacent main reinforcing ribs 21 can be increased, and the overall structural strength of the spare tire pool 2 can also be increased.

[0063] Furthermore, there is a height difference between the first auxiliary reinforcing rib 22 and the rib portion 211 of the main reinforcing rib 21. When there is a structural difference between the first auxiliary reinforcing rib 22 and the rib portion 211 to which it is connected, the gain in structural strength brought by the first auxiliary reinforcing rib 22 to the spare tire pool 2 will be more significant, and the spare tire pool 2 will have greater structural strength.

[0064] In one embodiment of the spare tire mounting bracket, a second auxiliary reinforcing rib 23 is also provided on the spare tire mounting bracket. The second auxiliary reinforcing rib 23 extends from the edge of the spare tire pool 2 to the bottom center of the spare tire pool 2 and connects with the rib portion 211 of a main reinforcing rib 21.

[0065] Specifically, there can be multiple second auxiliary reinforcing ribs 23, and these multiple second auxiliary reinforcing ribs 23 can be parallel to each other. For example, multiple second auxiliary reinforcing ribs 23 can all extend in the front-rear direction of the vehicle to which the spare tire mounting bracket is adapted. In addition, the multiple second auxiliary reinforcing ribs 23 can be intersecting (specifically, they can be actually intersecting or their extension lines can intersect each other).

[0066] In this embodiment, the second auxiliary reinforcing rib 23 can increase the structural strength of the area between the rib portion 211 to which it is connected and the edge portion of the spare tire pool 2, and also increase the overall structural strength of the spare tire pool 2.

[0067] Furthermore, there is a height difference between the second auxiliary reinforcing rib 23 and the rib portion 211 of the main reinforcing rib 21, which can be, for example, 9 mm, and the depth of the rib portion 211 of the main reinforcing rib 21 is greater than the depth of the second auxiliary reinforcing rib 23. With this structural difference between the second auxiliary reinforcing rib 23 and the rib portion 211 it connects to, the structural strength gain of the second auxiliary reinforcing rib 23 on the spare tire pool 2 will be more significant, resulting in greater structural strength for the spare tire pool 2.

[0068] In one embodiment of the spare tire mounting bracket, a third auxiliary reinforcing rib 24 is also provided on the spare tire mounting bracket. The third auxiliary reinforcing rib 24 is located between the two main reinforcing ribs 21 and extends from the edge of the spare tire pool 2 towards the center. Specifically, as described later, a boss 25 or other structure is provided in the bottom central region of the spare tire pool 2. The third auxiliary reinforcing rib 24 does not connect with the boss 25 or other structure at its extension end towards the bottom central region of the spare tire pool 2, but maintains a certain distance.

[0069] In this embodiment, the third auxiliary reinforcing rib 24 can increase the structural strength of the spare tire pool 2 in the area between the two main reinforcing ribs 21.

[0070] In summary, the main reinforcing rib 21, the first auxiliary reinforcing rib 22, the second auxiliary reinforcing rib 23, and the third auxiliary reinforcing rib 24 form an overall reinforcing skeleton within the area of ​​the spare tire pool 2. The first auxiliary reinforcing rib 22, the second auxiliary reinforcing rib 23, and the third auxiliary reinforcing rib 24 are added to areas not covered by the main reinforcing rib 21. These first auxiliary reinforcing ribs 22, the second auxiliary reinforcing rib 23, and the third auxiliary reinforcing rib 24 may or may not be connected to the main reinforcing rib 21, thus reinforcing the structural strength of areas not covered by the main reinforcing rib 21. In this way, the main reinforcing rib 21, the first auxiliary reinforcing rib 22, the second auxiliary reinforcing rib 23, and the third auxiliary reinforcing rib 24 form a multi-layered reinforcing rib structure covering all areas of the spare tire pool 2, giving the spare tire pool 2 a large and uniform structural strength as a whole.

[0071] In one embodiment of the spare tire mounting bracket, the connection portion 212 of each main reinforcing rib 21 has a chamfered shape. By providing a chamfered shape at the connection portion 212, the structural strength of the bottom of the spare tire pool 2 can be increased.

[0072] In one embodiment of the spare tire mounting bracket, at least one end of the rib portion 211 extends to the top of the spare tire pool 2, and a flat chamfered transition area is provided at the end of the top of the spare tire pool 2. By providing a flat chamfered transition area at the end of the rib portion 211 that connects to the top of the spare tire pool 2, the structural strength at that connection point can be increased.

[0073] In one embodiment of the spare tire mounting bracket, each main reinforcing rib 21 has a drain hole 213 at its connection 212.

[0074] The main reinforcing rib 21 is generally presented as a groove structure on the spare tire mounting bracket. The connecting part 211 of the main reinforcing rib 21 is located at the bottom of the spare tire pool 2. Therefore, the connecting part 211 is generally the lowest part of the spare tire mounting bracket. In this embodiment, by providing a drain hole 213, during the coating process, electrophoretic liquids and the like can flow along the groove formed by the main reinforcing rib 21, and can better flow out of the spare tire pool 2 from the drain hole 213.

[0075] In one embodiment of the spare tire mounting bracket, the bottom of the main reinforcing rib 21 and the second auxiliary reinforcing rib 23 is provided with a plurality of welding bolts 26, which are used for welding connection with the heat insulation plate.

[0076] In this embodiment, by setting welding bolts 26, the heat insulation plate can be welded to the spare tire mounting bracket, and the welded heat insulation plate can protect the spare tire pool 2.

[0077] Specifically, the depth of the second auxiliary reinforcing rib 23 is lower than the depth of the rib section of the main reinforcing rib 21, thus creating a gap between the rear floor silencer and the floor. This gap can be used to discharge heat damage in subsequent processes, reducing the risk of heat damage.

[0078] In one embodiment of the spare tire mounting bracket, the flat portion 1 is provided with a boss 11 and a decorative panel mounting hole 12. The boss 11 includes a basic rectangular shape and an upwardly angled reinforcing rib. The endpoint of the angled reinforcing rib has a chamfered area between it and the wall panel of the spare tire tank 2 to facilitate the flow of liquid from this chamfered area into the spare tire tank 2 and out through a drain hole 213 at the bottom of the spare tire tank 2. The boss 11 is also used to weld a carbon canister mounting bracket 4 onto it. Welding the carbon canister mounting bracket 4 onto the boss 11 ensures the torsional strength of the carbon canister mounting bracket 4. The decorative panel mounting hole 12 can be used to install and secure a decorative panel for the luggage compartment.

[0079] A fourth auxiliary reinforcing rib 13 is also provided on the flat part 1. There can be multiple fourth auxiliary reinforcing ribs 13, which can be located on opposite sides of the flat part 1, such as the left and right sides (with reference to the spare tire tank 2). In actual implementation, the fourth auxiliary reinforcing rib 13 and the decorative panel mounting hole 12 are staggered. When the decorative panel mounting hole 12 is located along the length of the fourth auxiliary reinforcing rib 13, the fourth auxiliary reinforcing rib 13 avoids and bypasses the decorative panel mounting hole 12. Drainage holes can also be provided on the fourth auxiliary reinforcing rib 13 to facilitate the drainage of electrolytes and other substances during the coating process.

[0080] In one embodiment of the spare tire mounting bracket, a strip-shaped boss 25 is provided at the bottom center of the spare tire pool 2, and a spare tire mounting bracket 3 is fixed on the boss 25.

[0081] Specifically, the circumferential edge of the boss 25 can be chamfered to create a smooth transition with the bottom of the spare tire well 2. A fifth auxiliary reinforcing rib 251 is provided on the boss 25, extending from the center of the boss 25 along the length of the boss 25 to the chamfered edge of the boss 25. The spare tire mounting bracket 3 can be fixed to the boss 25 by welding or other methods.

[0082] In this embodiment, by providing a boss 25, a chamfer on the circumferential edge of the boss 25, and a fifth auxiliary reinforcing rib 251 on the boss 25, the structural strength of the bottom of the spare tire pool 2 can be enhanced independently. The combined effect of these three elements maximizes the enhancement of structural strength. Furthermore, fixing the spare tire mounting bracket 3 to the boss 25 increases the installation torque of the spare tire and improves the durability of loading and unloading it.

[0083] In one embodiment of the vehicle of the present invention, the vehicle includes the spare tire fixing member described in the above embodiments.

[0084] The vehicle in this embodiment of the invention includes the spare tire mounting bracket described above, and naturally has the same beneficial effects as the spare tire mounting bracket described above, which will not be repeated here.

[0085] The above embodiments are merely preferred embodiments provided to fully illustrate the present invention, and the scope of protection of the present invention is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present invention are all within the scope of protection of the present invention.
