Description

BACKGROUND OF THE INVENTION Technical field

[0001] The present invention relates to a fastening arrangement for a vehicle and in particular to a fastening arrangement for a vehicle which prevents the coupling between parts from disengaging due to the separation of a hook from a stop projection in a hook structure. Description of the state of the art

[0002] With the ongoing development of vehicle technologies and consumer demand for low vibration and noise levels, efforts are being made to maximize driving comfort by analyzing noise, vibration, and shock within vehicles. Engine vibrations generated within a specific RPM range while the vehicle is running are transmitted through the vehicle body into the interior at a specific frequency, and the frequency component of the engine's ignition also affects the vehicle's interior.

[0003] In a vehicle's engine, vibration is structurally generated due to the periodic change in the central position caused by the reciprocating motion of the piston and connecting rod, the inertial force exerted along the cylinder axis by the reciprocating section, the inertial force caused by the connecting rod oscillating to the left and right of the crankshaft, periodic changes in the torque applied to the crankshaft, and similar factors. Accordingly, an engine mount is positioned between the engine and the vehicle body to support the engine and dampen noise and vibrations transmitted from it. Engine mounts are classified into rubber mounts, air-damping mounts, and liquid-filled engine mounts.

[0004] The rubber motor mount, typically made of a rubber material, is susceptible to low-frequency / high-amplitude vibration, and its damping performance is insufficient for both high-frequency / low-amplitude and low-frequency / high-amplitude vibrations. Accordingly, the liquid-encapsulated motor mount is widely used because it can absorb and dampen vibrations across a broad frequency range, including high-frequency / low-amplitude and low-frequency / high-amplitude vibrations, that are transmitted to the motor mount due to motor operation.In the fluid-encapsulated engine mount, also known as a fluid mount or hydraulic mount, a damping force is generated when the fluid enclosed under the insulator flows through a flow path between an upper and a lower fluid chamber. The fluid-encapsulated engine mount is capable of damping both high-frequency vibrations (low-amplitude vibrations) and low-frequency vibrations (large-amplitude vibrations).

[0005] In recent years, active and semi-active mounts have been developed to improve the vibration isolation properties of liquid-encapsulated engine mounts. Furthermore, reducing a vehicle's weight is linked to fuel efficiency, collision performance, and ease of assembly. The engine mount system has also been developed with a shift in materials from steel to aluminum and plastic for lighter weight, and plastic components, such as plastic cores, brackets, openings, and the like, are increasingly being used.

[0006] However, to achieve reduced weight by replacing the material of the parts with plastics, the mounting of the components within the mounting system must be carefully considered, as plastic parts exhibit strength and tolerance issues compared to steel or aluminum parts. Therefore, the robustness of the assembly is a key factor when using plastic materials. A representative example is a mounting structure for a plastic cover (e.g., a bearing cover) that utilizes a hook structure, a fastening method that employs multiple hooks. Since strength and tolerance can be adjusted by varying the number of hooks, the hook structure is widely used.

[0007] However, the use of a hook structure for fastening parts is insufficient in terms of fastening force and assembly robustness. In other words, the fastening force between the parts is weak, and if the hooks move away from the corresponding parts due to vibrations, they can detach. Furthermore, the stiffness at a central bolt (e.g., the stiffness at the mounting point) is low for the conventional mounting because the bearing height of the inner core and the central bolt coupled to the motor is high relative to the bearing surface of the lower side.

[0008] To compensate for the low stiffness at the entry point, a mass damper is arranged on the bracket or mounting bracket. However, the weight of this mass damper prevents any reduction in the vehicle's weight. Furthermore, because the bracket's opening is located near the tire well, the potential for height reduction is limited. Additionally, reducing the size of the rubber isolator is difficult. Therefore, a technique was developed to reduce the size of the opening in order to lower the bracket's height. The bracket's height can be reduced by decreasing the size of the opening through the application of the hook structure described above. However, because the hook structure has insufficient fastening force and mounting robustness, as described above, its application is challenging.

[0009] To facilitate understanding of the present invention, a problem of a bracket and a hook structure applied to the bracket according to the prior art is described in more detail.

[0010] First, a prior art device is designed such that a bearing cover can be hook-coupled to an elastic support, thereby integrally coupling the bearing cover, a bellows, a barrier, and the elastic support, which are components of a support. In this reference, the support is referred to as the bearing, a membrane as the bellows, and an opening plate as the barrier. Since this support design changes the conventional forced press-fit assembly method to the hook-fit method, in which the components of the support are coupled using a hook structure of the bearing cover, the size of the opening arrangement is reduced and the height of the support is decreased, thereby reducing weight and cost.

[0011] The hook structure is easily detachable and merely connects the components of the bracket, maintaining their assembled state before they are attached to a vehicle body. However, the hook structure is not intended to couple or support a pre-assembled unit with an insulator to a mounting bracket attached to the side of the vehicle body. Therefore, when the bracket is attached to the vehicle body, it is supported by a separate subframe or similar structure. If the subframe is unusable, the bracket's use is limited.

[0012] When the bracket is attached and secured to the vehicle body using a metal mounting bracket (e.g., an aluminum alloy), a housing for the mounting bracket is generally attached to surround the bracket. Specifically, a lower end section of the housing is rolled (e.g., curved) to abut the lower section of the bearing cover, allowing the housing to hold the lower section of the bearing cover in place. As a result, the lower side of the bearing cover is hooked by the lower end section of the curved housing, as described above, enabling the housing to retain the bearing cover.Accordingly, the housing of the mounting bracket is rolled up within the structure to allow the lower end section of the housing to surround the underside of the bearing cover from its side surface. Specifically, the mounting bracket is manufactured from a high-tensile aluminum alloy.

[0013] However, if high-elongation aluminum materials are used, the cost is high and strength and stiffness are low. When high-strength, high-stiffness aluminum is used, the elongation is low, and cracks occur during the coiling of the housing, resulting in a high failure rate. Accordingly, a pipe with the attached insulator of the bracket can be forcibly pressed into the housing of the metal (e.g., aluminum) mounting bracket, but this forced press-fit method makes it difficult to secure the parts together.

[0014] Furthermore, the bracket and the mounting bracket are fastened by a hook structure, and the hook structure for attaching the bracket to the mounting bracket is in the Fig. 10 and Fig. 11 shown. Fig. 10 is a cross-sectional view showing a fastening arrangement in the prior art, and Fig. Figure 11 is an enlarged cross-sectional view of section A in Fig. 10. As shown in the drawings, a support bracket 160 is used to connect a bracket 100 to a mounting bracket 170 for attaching the bracket to a vehicle body.

[0015] The support bracket 160, which is an annular bracket firmly connected to a lower section of the bracket 100, is fitted into the lower section of the bracket 100 via an opening arrangement 140 and has a plurality of hooks 164 along a circumferential direction. When the hooks 164 of the support brackets 160 are connected to a housing 171 of the mounting bracket 170, the bracket 100 is thus connected to the mounting bracket 170 via the support bracket 160. In particular, the hook structure for coupling and fastening the bracket 100 to the mounting bracket 170 using the hooks 164 comprises the hooks 164 formed on the support bracket 160, and the hooks 164 of the support bracket 160 are coupled to stop projections 173 of the mounting bracket 170, thereby connecting the bracket 100 to the mounting bracket and simultaneously maintaining the assembled state.

[0016] The hooks 164 of the support bracket 160 are designed such that they are hook-coupled to the stop projections 173 on a groove 172 formed on an inner surface of the housing 171 of the mounting bracket 170, and to the stop projections 173, respectively, with the bracket 100 coupled to the support bracket 160 being supported by the mounting bracket 170. In this design, which uses the hook structure, the stiffness at the bracket entry point is increased due to the reduced height of the bracket, and the weight is reduced due to the application of the plastics. Furthermore, since the hooks are elastic structures for the hook coupling and are arranged within the mounting bracket, the layout is also improved.

[0017] However, the hook structure exhibits insufficient fastening strength and robustness. In other words, the fastening force between the parts provided by the hooks is weak, and the part can easily separate from the other part if the hooks move relative to the counterpart due to vibrations or similar factors. Fig. Figure 11 is a view illustrating a hook structure of a fastening arrangement in the prior art. As in Fig. Figure 11 shows that if the hooks 164, which are formed in the support bracket 160 from a plastic material (e.g., a synthetic resin), are bent by force due to vibrations or the like, the components of the bracket 100, like an insulator 130, are separated from the mounting bracket 170 to the lower side. In other words, if the hooks 164 are moved or bent in the release direction rather than in the coupling direction with respect to the stop projections 173 of the mounting bracket 170, the components of the bracket 100, which have the insulator 130, can be separated from the mounting bracket 170.

[0018] Examples of previously known configurations of a fastening arrangement can be found in DE 10 2015 118 931 A1, DE 10 2014 226 091 A1 and DE 10 2010 004 381 A1.

[0019] The foregoing is intended only to contribute to an understanding of the background of the present invention and is not intended to imply that the present invention falls within the field of prior art which is already known to the person skilled in the art. PRESENTATION OF THE INVENTION

[0020] Accordingly, the object of the present invention is to provide a fastening arrangement for a vehicle which is able to prevent the loosening of the coupling between parts due to the separation of a hook from a stop projection in an embodiment in which a hook structure is used.

[0021] This problem is solved by a fastening arrangement with the features of claim 1. Further embodiments can be found in the dependent claims.

[0022] To achieve the above objective, the mounting bracket can include a support bracket for a vehicle-internal device and a support bracket that is coupled to and thus locked with the mounting bracket. The support bracket can have a first hook. The mounting bracket can further include a mounting bracket configured to couple the mounting bracket to a side of the vehicle body and to support the mounting bracket. The mounting bracket can have a housing to which the mounting bracket is coupled and a first stop projection to which the first hook of the mounting bracket is hook-coupled, enabling the support bracket to be coupled and fixed to the mounting bracket by coupling between the first hook and the stop projection.In particular, the fastening arrangement may further include a wedge ring to support the first hook coupled to the first stop projection from behind while it is attached to a lower outer circumferential surface of the bracket, in order to prevent the first hook from bending backwards and becoming separated from the first stop projection of the fastening bracket.

[0023] According to the vehicle mounting arrangement of the present invention, a wedge ring is provided for supporting and locking a hook with a coupled mounting bracket, in order to prevent the hook of the mounting bracket from being moved or bent due to the wedge ring. Therefore, the hook cannot be released, the hook-coupled state can be maintained, and thus the separation of the bracket, including the insulator, can be effectively prevented.

[0027] Exemplary embodiments of the present invention are described below with reference to the accompanying drawings. However, the present invention is not limited to the exemplary embodiments presented here, and the person skilled in the art will recognize that the present invention can be implemented in many alternative forms.

[0028] In the present invention, the fastening arrangement can include a support bracket made of a plastic material to prevent the hooks of the support bracket from being moved or bent by forces due to vibration or the like. An anti-release structure can support and lock the hooks that engage with the fastening brackets and hold the hooks firmly in the engaged state.

[0030] A mounting arrangement for a vehicle according to an exemplary embodiment of the present invention for supporting an internal vehicle device can include an engine mounting arrangement for supporting an engine. The engine mounting arrangement can include a bracket 100 configured to support an internal vehicle device; a support bracket 160 coupled to and locked to the bracket 100; and a mounting bracket 170 configured to attach the bracket 100 to a side of the vehicle body and to hold the mounting bracket 170 so that it is coupled to the bracket 100 and the support bracket 160.Furthermore, in the arrangement for a vehicle according to an exemplary embodiment of the present invention, the bracket 100 can have a central bolt 110 which is attached to a motor side; an inner core 120, wherein the central bolt engages with it; and the insulator 130 made of a rubber material which is designed to be integrally coupled with the inner core 120.

[0031] The insulator 130 can fix and support the inner core 120 and, together with the opening arrangement 140 below the insulator, can form an upper liquid chamber C1. The inner core 120 can be made of a metallic material, for example, an aluminum alloy, or it can be made of a plastic material (e.g., synthetic resin). A tube 131 can be connected to a lower section of the insulator 130, the tube 131 being made of a plastic material. After the inner core 120, in which the central bolt 110 is located, has been manufactured, the inner core 120 and the tube 131 can be fixed in the mold, and then the rubber insulator 130 can be formed so that it is integrally coupled with the inner core 120 and the tube 131 through a curing process.

[0032] The opening arrangement 140 can include an opening plate 141 and a membrane (not shown). The opening plate 141 can be positioned laterally in the holder 100 at a location below the insulator 130 to divide a liquid chamber in the holder 100 into an upper liquid chamber C1 and a lower liquid chamber C2. The opening plate 141 can include an upper plate 142 and a lower plate 143. Furthermore, the opening plate 141 can include an opening 144 that forms an annular bypass flow path (also referred to as an inertial path) for guiding a fluid flow between the upper liquid chamber C1 and the lower liquid chamber C2. The opening plate 141 can have a first opening that allows a connection between the opening 144 and the upper liquid chamber C1, and a second opening that allows a connection between the opening 144 and the lower liquid chamber C2.

[0033] Accordingly, the upper liquid chamber C1, the opening 144, and the lower liquid chamber C2 can be interconnected through the openings of the opening plate 141 to allow the fluid to flow between them. Thus, the opening 144 can provide a flow path for the fluid and be interconnected with the upper liquid chamber C1 and the lower liquid chamber C2 through the openings, thereby creating a fluid passage connecting the upper liquid chamber C1 and the lower liquid chamber C2—that is, a flow path that allows the fluid to move between the liquid chambers C1 and C2 on both sides. Furthermore, a membrane 150 can be arranged below the opening plate 141, and both the opening plate 141 and the membrane 150 can form the lower liquid chamber C2.

[0034] As described above, after the rubber insulator 130, which is integrally connected with the inner core 120 and the tube 131, is formed by a curing process, a wedge ring 166 can be attached to a lower outer circumferential surface of the bracket 100, i.e., to the outer circumferential surface of the tube 131. Subsequently, the opening assembly 140, with the upper plate 142 and the lower plate 143 of the opening plate 141 and the membrane (not shown) positioned between the upper plate 142 and the lower plate 143, can be assembled to form a lower end section of the insulator 130. After the membrane 150 is attached to a lower section of the opening assembly 140, the retaining clip 160 can be attached to a lower side of the membrane 150 by means of a hook structure, as described below.

[0035] In the bracket 100 described above, the interior of the bracket 100, including the upper liquid chamber C1 and the lower liquid chamber C2, can be filled with liquid and sealed, and the bracket 100 can be connected to the mounting bracket 170 for attachment to the vehicle body. In particular, the lower section of the bracket 100 can be attached to the mounting bracket 170 using the support bracket 160, employing a hook-coupling method in which the hooks 164 of the support bracket 160 are locked to the mounting bracket 170. Here, the lower section of the bracket 100 can refer to the lower part of the bracket 100 where the tube 131, the opening arrangement 140, and the diaphragm 150 are located.

[0036] In an exemplary embodiment of the present invention, the support bracket 160 can be attached to the mounting bracket 170 by means of the hook structure, while it is coupled to the lower section of the bracket 100, thereby integrally connecting and securing the lower section of the bracket 100 to the mounting bracket 170. Furthermore, the support bracket 160 can have a hook structure that is attached to the lower section of the bracket 100. Accordingly, in an exemplary embodiment of the present invention, the support bracket 160 can have a hook structure that is attached to both the mounting bracket 170 and the lower section of the bracket 100.

[0037] Furthermore, the support bracket 160 can have an annular ring 161 that is coupled along the entire lower section of the bracket 100 to abut the lower section of the bracket 100 and support the bracket 100 by surrounding it. The support bracket 160 can also have a hook structure formed on the ring 161 and attached to the mounting bracket 170. Additionally, the support bracket 160 can have a hook structure that is attached to the lower section of the bracket 100.

[0038] In particular, the ring 161 of the support bracket 160 can have an annular bottom section 162, configured to couple with a lower surface of the bracket 100, i.e., the edge section of the membrane 150, to abut the annular bottom section 162 while coupled with the lower section of the bracket 100, and an annular side section 163, which extends integrally upward from the bottom section 162 and is arranged to surround the lower side surface of the bracket 100, i.e., a side surface of the opening arrangement 140. The bottom section 162 and the side section 163 can be integrally formed to create the ring 161, and the bottom section 162 can support the edge of the membrane 150, which is the lower surface of the bracket 100.

[0039] Furthermore, the side section 163 of the ring 161 can be integrally provided with a hook structure for connecting the mounting bracket 170 and the lower section of the bracket 100. The hook structure can have a first hook 164 for attachment to the mounting bracket 170 and a second hook 165 for attachment to the lower section of the bracket 100. The first hook 164 and the second hook 165 can be configured to extend upwards from an outer circumferential surface of the ring 161 (i.e., an outer circumferential surface of the side section). An end section of the first hook 164 can be configured with a stop end 164a for downward hook-coupled to the first stop projections 173 on the groove 172 formed on the inner surface of the housing 171 of the mounting bracket 170.

[0040] An end section of the second hook 165 can be configured with a stop end 165a to be hook-coupled downwards to the lower section of the support 100, and in particular to be hook-coupled to a second stop projection 132 that projects from the outer circumferential surface of the tube 131 which is connected to the insulator. In particular, each hook can be configured such that the upper end of the first hook 164 can be positioned higher than the upper end of the second hook 165.

[0041] The first hook 164 can be arranged inside the housing 171 of the mounting bracket 170 to be attached to the first stop projections 173 of the housing 171 located outside the first hook 164, and the second hook 165 can be attached to the second stop projection. Accordingly, the stop end 164a can project outwards from the upper end section of the first hook 164, and the stop end 165a can project inwards from the upper end section of the second hook 165.

[0042] In an exemplary embodiment, several first hooks 164 and second hooks 165 can be arranged at predetermined intervals along a circumferential direction in the ring 161. As shown in Fig. As shown in Figure 5, each first hook 164 and each second hook 165 can be arranged alternately one behind the other in the circumferential direction of the ring 161 of the support bracket 160. Furthermore, in the exemplary embodiment of the present invention, the support bracket 160 can be made of and manufactured from a plastic material (e.g., a synthetic resin), and thus the first hook 164 and the second hook 165 can have elastic (e.g., resilient) structures.

[0043] The first hook 164 can engage with the first stop projections 173 formed on the inner circumferential surface of the housing 171 of the mounting bracket 170. Following the insulator 130, the opening arrangement 140, the diaphragm 150, and the like are assembled. The assembled bracket 100 can be pressed into the housing 171 of the mounting bracket 170, thereby securing the hook structure. During pressing, the first hook 164 and the second hook 165 can be bent (e.g., elastically deformed) in a direction opposite to the direction of attachment due to the contact surfaces. Once the hook is press-fitted into the predetermined position, the hooks can be restored to their elasticity, and the stop ends 164a and 165a of the hooks can engage with the respective stop projections 132 and 173.

[0044] In other words, before the first hook 164 engages with the first stop projections 173 of the fastening bracket 170, the first end 164a of the first hook 164 is in contact with the inner circumferential surface of the fastening bracket 170. The hook 164 is deformed inwards, and the stop end 164a of the first hook 164 reaches the groove 172 of the fastening bracket 170. The first hook 164 can be returned to its original shape by elasticity, and the stop end 164a of the first hook 164 can be stopped by the first stop projection 173 of the groove 172.Similarly, the second hook 165 is attached to the second stop projection 132 of the tube 131, which is the lower section of the bracket 100. While the stop end 165a of the second hook 165 is in contact with the outer circumferential surface of the tube 131, the second hook 165 may be deformed outwards, and the stop end 165a of the second hook 165 may slide over the second stop projection 132. Accordingly, the second hook 165 may be returned inwards to its original shape by elasticity, and the stop end 165a of the second hook 165 may be stopped by the second stop projection 132.

[0045] To prevent the first hook 164 from separating from the first stop projections 173 of the mounting bracket 170, the mounting arrangement, according to an exemplary embodiment of the present invention, can include the wedge ring 166, which holds the first hook 164 in engagement with the first stop projections 173 on the inside of the first hook, in order to prevent the first hook 164 from being bent inwards (e.g., deflected). If the first hook 164 is bent inwards, the stop end 164a can be separated from the first stop projections 173 of the mounting bracket 170 located outside the stop end, thereby releasing the mounting state of the first hook 164 with the mounting bracket 170.Accordingly, in the present invention, the wedge ring 166, which holds back the first hook 164 from the inside of the first hook 164, can be assembled to prevent the first hook 164 from being separated from the first stop projections 173.

[0046] The wedge ring 166 can be manufactured and formed from a plastic material (e.g., synthetic resin), and the wedge ring 166 can be elastic and essentially circular. How Fig. As shown in Figure 2, the wedge ring 166 can have a shape in which at least one side is open to be radially expandable (i.e., opened). In an exemplary embodiment, the wedge ring 166 can have a shape in which the first and second sides are open, as shown in Figure 2. Fig. 2 shown, and the wedge ring can be manufactured in such a way that it is divided into two parts by a length of a semicircle.

[0047] In other words, a wedge ring 166 can have two semicircular elements 166a. The two semicircular elements 166a can be arranged in a circle along the lower outer circumferential surface of the holder 100 (the outer circumferential surface of the tube 131). In the assembled state, as shown in the Fig. 1A to 1F shown, while the central bolt 110, the inner core 120, the insulator 130, the tube 131, the opening arrangement 140 and the diaphragm 150 are assembled (see Fig. 1A), the wedge ring 166 is first assembled to be positioned on the lower outer circumferential surface of the bracket 100 (see Fig. 1B), and then the support bracket 160 can be coupled to the lower section of the bracket 100 from the bottom to the top (see Fig. 1C).

[0048] During this process, the second hook 165 of the support bracket 160 can be connected to the lower section of the bracket 100 and, in particular, to the stop projection 132, which projects from the outer circumferential surface of the tube 131 arranged on the lower section of the bracket 100, thereby enabling the support bracket 160 to be attached to the lower section of the bracket 100. Specifically, the wedge ring 166 can be positioned at a location lower than the stop end 164a of the first hook 164, while it is positioned at a location higher than the stop end 165a of the second hook 165 and the second stop projection 132.

[0049] The mounting bracket 170 can then be assembled (see Fig. 1D and Fig. 1E). After the bracket 100 is inserted into the housing 171 of the mounting bracket 170, the support bracket 160 coupled to the bracket 100 can be hook-coupled to the first bracket 164 on the mounting bracket 170. In other words, the first hook 164 of the support bracket 160 can be hook-coupled to the first stop projections 173 in the groove 172 formed on the inner surface of the housing 171 of the mounting bracket 170, and the stop end 164a of the first hook 164 can be hook-coupled downwards to the first stop projection 173 while it is inserted into the groove 172. The wedge ring 166 can be positioned at a location below the stop end 164a of the first hook 164 and the first stop projections 173.

[0050] Furthermore, the wedge ring 166 can be pushed upwards with a clamping device 10, as described below, and as a result, the wedge ring 166 can be moved upwards and can support the end section of the first hook 164 at a point where the stop end 164a is located, which is the upper end section of the first hook from the rear, i.e., from the inside (see Fig. 1F and Fig. 3) As described above, if the wedge ring 166 is moved upwards, as in Fig. As shown in Figure 3, the moving wedge ring 166 is arranged between the tube 131, which is the lower section of the bracket 100, and the first hook 164, which is hook-coupled with the first stop projections 173.

[0051] As a result, the wedge ring 166 can support the upper end section of the first hook 164 from the inside, so that after assembly, the wedge ring 166 can prevent the first hook 164 from bending inwards, and thus the stop end 164a of the first hook 164 can be prevented from being separated from the first stop projections 173, and the fastening state of the first hook 164 can be prevented from being loosened.

[0052] Referring to Fig. 3. The support bracket 160 can be coupled to the mounting bracket 170 to allow the stop end 164a of the first hook 164 to be hooked onto the first stop projections 173 of the mounting bracket 170, and the wedge ring 166 can be positioned on the lower side and moved upwards to support and lock the first hook 164 from behind (from the inside) to prevent the first hook 164 from being released, i.e., the stop end 164a can be prevented from being released from the first stop projections 173.

[0053] Fig. Figure 4 shows a further exemplary embodiment of the present invention, in which the fastening arrangement is provided with a sliding guide section 134 and a locking projection 133. As in Fig. As shown in Figure 4, the fastening structure can be arranged in the bracket 100 to fix the wedge ring 166 in a position where the wedge ring 166 locks the first hook 164 to prevent the first hook 164 from being released. In other words, the wedge ring 166 can be moved upwards to support the first hook 164. When the wedge ring 166 is pushed upwards by the fastening structure into the locking position of the first hook 164, the wedge ring 166 can slide past this fastening structure, and after passing the fastening structure, the wedge ring 166, which locks the first hook 164, can be hook-coupled downwards to prevent it from moving downwards. Thus, the downward movement of the wedge ring 166 can be restricted.

[0054] In an exemplary embodiment, the fastening structure can have the locking projection 133, which projects from the lower outer circumferential surface of the bracket 100, which faces the upper end section of the first hook 164, i.e., projects from the outer circumferential surface of the tube 131, in order to prevent the wedge ring 166, which locks the first hook 164, from being moved downwards due to its engagement.

[0055] The wedge ring 166 can be moved upwards and can pass the locking projection 133, and can then be stopped by the locking projection at a position above it. Therefore, the wedge ring 166, with its downward movement clamped by the locking projection 133, can support the upper end section of the first hook 164, and consequently, the separation of the first hook 164 due to the downward movement of the wedge ring 166 can be prevented.

[0056] Furthermore, in an exemplary embodiment, the lower surface of the holder 100 below the locking projection 133 can be formed with the sliding guide section 134, which has a cross-section with an inclined structure to facilitate the upward movement of the wedge ring 166. The sliding guide section 134 can be formed with an inclined surface on the lower surface of the holder 100 below the outwardly projecting locking projection 133, which is located on the outer circumferential surface of the tube 131, to allow the wedge ring 166 to move upward and slide, while simultaneously allowing the wedge ring 166 to expand radially.

[0057] In particular, the inclined surface can be formed in the cross-sectional shape of the tube 131, as shown in Fig. Figure 4 shows that the outer diameter of the tube 131 can gradually increase towards its upper section. When the wedge ring 166 is located below the sliding guide section 134 and is pushed upwards by the clamping device 10 described below, the upwardly moving wedge ring 166 can slide along the surface (the inclined cross-sectional area) after contacting the sliding guide section 134. Thus, the upwardly moving wedge ring 166 can move on the inclined surface of the sliding guide section 134, and at the same time its diameter can increase, causing it to slide over the locking projection 133.

[0058] The sliding guide section 134 with the inclined cross-sectional surface can be formed below the locking projection 133, which makes it easier to push the wedge ring 166 upwards. When the wedge ring 166 is pushed from below towards the clamping device 10, it can open radially to slide more easily over the locking projection 133. As the wedge ring 166 moves along the sliding guide section 134 and then crosses the locking projection 133, it can support the first hook 164 from behind. The locking projection 133 prevents the wedge ring 166 from separating downwards, thus achieving a locked state to maintain the hook-coupled condition.

[0059] Furthermore, it shows Fig. 7 a perspective view showing a clamping device for mass production to push the wedge ring upwards and Fig. 8 and Fig. Figures 9 are enlarged perspective views showing the states before and after the wedge ring is moved upwards in the fastening arrangement according to an exemplary embodiment of the present invention. The device 10 can be a mass-produced fastening tool for moving the wedge ring 166 into a fixed position relative to the first hook 164 and can have pins 13 that are inserted through a space between the first hook 164 and the second hook 165 to allow the inserted pins 13 to push the wedge ring 166 upwards.

[0060] The clamping device 10 can be made of a metallic material such as steel and can comprise a plate 11, a rod 12 coupled to the lower section of the plate 11, and pins 13 provided on an upper section of the plate 11. The pins 13 can be arranged at predetermined intervals on the upper surface of the plate 11 and can, in particular, be arranged in a circular pattern at predetermined intervals along the circumferential direction. Furthermore, the rod 12 can be coupled to a device (not shown) for vertically moving the device 10. For example, the rod 12 can be coupled to a piston of a cylinder mechanism (not shown).

[0061] To use the clamping device 10, as described in the Fig. 5 and Fig. As shown in Figure 6, a space can be provided between each of the first hooks 164 and the second hook 165 to allow the insertion and movement of the pins 13 of the clamping device 10, and a pin channel 161a can be formed on the outer circumferential surface of the side section 163 of the support bracket 160 to allow the pin 13 to be inserted into each space through the pin channel 161a. A plurality of pin channels 161a can be arranged at predetermined intervals on the outer circumferential surface of the side section of the support bracket 160 along the circumferential direction.

[0062] As a result, as in Fig. Figure 6 shows that when the rod 12 engages with the piston of the cylinder mechanism, and the cylinder mechanism operates to move the piston upwards, the pins 13 of the device 10 are inserted through the pin channels 161a and move between the first hook 164 and the second hook 165. Thus, the pins 13, moving upwards, can simultaneously push the wedge ring 166 upwards in any position. Accordingly, the wedge ring 166 can be pushed upwards by the pins 13 of the clamping device 10 and, as described above, can pass the locking projection 133 and move into a position that locks and supports the first hook 164, which is coupled to the first stop projections. Therefore, the assembly of the bracket 100, the support bracket 160, and the fastening bracket 170 can be completed. Fig. Figure 8 shows a state before the pins 13 of the clamping device 10 are moved upwards, and in this state the wedge ring 166 can be positioned on the lower side.

[0063] Furthermore, it shows Fig. 9 a state after the pins 13 of the clamping device 10 have been moved upwards, and in this state the first hook 164 can be hook-coupled with the first stop projections 173, and when the clamping device 10 is moved upwards, the pins 13 can push the wedge ring 166 upwards. Accordingly, the wedge ring 166 can support the upper end section of the first hook 164 from behind, thereby allowing the stop end 164a to be in the locked state, preventing the stop end from being separated from the first stop projections 173.
