[0052] The accompanying drawings of the present invention Figures 1 to 7 A roof rack according to a preferred embodiment of the present invention is shown. The roof rack 100 includes at least two locking devices 10 and a luggage rack 20. At least one locking device 10 is provided on opposite sides of the luggage rack 20. The locking device 10 is used to mount the luggage rack 20 on a roof 200. The locking device 10 creates a gap between the luggage rack 20 and the roof 200 to prevent the luggage rack 20 from directly contacting the roof 200, thereby protecting the roof 200.

[0053] Reference Attachment Figures 8 to 22 The locking device 10 includes a base unit 11 and a lock unit 12, the base unit 11 is fixedly mounted on the roof 200, and the lock unit 12 is fixedly mounted on the luggage rack 20, wherein the locking device 10 has a locked state and an unlocked state, and the locking device 10 can switch between the locked state and the unlocked state. When the locking device 10 is in the locked state, the base unit 11 locks the lock unit 12, and the luggage rack 20 is reliably maintained above the roof 200. When the locking device 10 is in the unlocked state, the base unit 11 releases the lock unit 12, so that the lock unit 12 can move away from the base unit 11, thereby increasing the gap between the luggage rack 20 and the roof 200, thereby facilitating the cleaning of the roof 200.

[0054] Specifically, the base unit 11 includes a fixing assembly 111 and a locking arm 112 provided on the fixing assembly 111 . The fixing assembly 111 can be fixedly mounted on the vehicle roof 200 . The locking arm 112 has a locking hole 1121 . The lock unit 12 includes a housing 121, a lock body 122, and a lock pin 123. The housing 121 can be fixedly mounted on the luggage rack 20. The lock body 122 is disposed on the housing 121, and the lock body 122 has a lock pin hole 1221 and an insertion slot 1222 connected to the lock pin hole 1221. The lock pin 123 has an operating end 1232 and a locking end 1231 corresponding to the operating end 1232. The locking end 1231 of the lock pin 123 is movably inserted into the lock pin hole 1221 of the lock body 122. When the locking end 123 of the lock pin 123 is moved, the locking end 1231 of the lock pin 123 is moved. When the locking end 1231 of the locking pin 123 is inserted into the locking hole 1121 of the locking arm 112, the locking device 10 is in the locked state. The base unit 11 locks the locking unit 12, and the luggage rack 20 is securely held above the roof 200. When the locking end 1231 of the locking pin 123 is moved away from the locking hole 1121 of the locking arm 112, the locking device 10 is in the unlocked state. The base unit 11 releases the locking unit 12, allowing it to move away from the base unit 11, thereby increasing the gap between the luggage rack 20 and the roof 200 and facilitating cleaning of the roof 200. In other words, by changing the position of the locking end 1231 of the locking pin 123, the locking device 10 can switch between the locked and unlocked states.

[0055] It is worth mentioning that the manner in which the fixing assembly 111 of the base unit 11 is fixedly mounted on the vehicle roof 200 is not limited in the roof rack 100 of the present invention. Figures 1 to 22 In this specific example of the roof rack 100 of the present invention, the fixing assembly 111 is fixedly mounted on the roof 200 by clamping an edge 201 of the roof 200 , wherein the edge 201 of the roof 200 may be a gutter of the roof 200 .

[0056] Specifically, the fixing assembly 111 includes a first clamping portion 1111 and a second clamping portion 1112. The first clamping portion 1111 and the second clamping portion 1112 are configured to provide a clamping force for clamping the edge 201 of the roof 200, so that the fixing assembly 111 is fixed to the roof 200 by clamping the edge 201 of the roof 200.

[0057] More specifically, the first clamping portion 1111 and the second clamping portion 1112 are both sheet metal parts, the first clamping portion 1111 includes a first connecting plate 11111 and a first clamping plate 11112 extending downward from the first connecting plate 11111 as a whole, the second clamping portion 1112 includes a second connecting plate 11121, a second clamping plate 11122 extending downward from the second connecting plate 11121 as a whole, and a third clamping plate 11123 extending outward from the second clamping plate 11122 as a whole, wherein the second connecting plate 11121 is located below the first connecting plate 11111, the second clamping plate 11122 is located on the outside of the first clamping plate 11112, and the third clamping plate 11123 is located below the first clamping plate 11112. The first connecting plate 11111 has at least one first plate hole 111110, and the second connecting plate 11121 has at least one second plate hole 111210. The position of the first plate hole 111110 of the first connecting plate 11111 corresponds to the position of the second plate hole 111210 of the second connecting plate 11121. The fixing assembly 111 further includes at least one first screw-mounted element 1113. The first screw-mounted element 1113 can be a screw, wherein the screw-mounted end of the first screw-mounted element 1113 passes through the second connecting plate 11121 in sequence. The second plate hole 111210 of the connecting plate 11121 and the first plate hole 111110 of the first connecting plate 11111 are screwed onto the inner wall of the first connecting plate 11111 for forming the first plate hole 111110, so that a clamping force is provided between the first clamping plate 11112 and the third clamping plate 11123 for clamping the edge 201 of the roof 200 between the first clamping plate 11112 and the third clamping plate 11123 to fixedly install the fixing assembly 111 on the roof 200.

[0058] In the attached Figures 1 to 22 In the illustrated embodiment of the roof rack 100 of the present invention, the locking arm 112 integrally extends upward from the first clamping portion 1111 of the fixing assembly 111, thereby attaching the locking arm 112 to the fixing assembly 111. In other words, the locking arm 112 and the first clamping portion 1111 are formed from the same sheet metal component, and the locking arm 112, the first connecting plate 11111, and the first clamping plate 11112 can be formed by bending a single metal plate at a predetermined position.

[0059] Reference Attachment Figures 8 to 15The fixing assembly 111 further includes a first isolation pad 1114 and a second isolation pad 1115, wherein the first isolation pad 1114 is arranged at the bottom of the first clamping plate 11112 of the first clamping portion 1111, for example, the first isolation pad 1114 can be sleeved on the bottom of the first clamping plate 11112, and the second isolation pad 1115 is arranged on the inner side of the second clamping plate 11122 of the second clamping portion 1112 and the upper side of the third clamping plate 11123, for example, the second isolation pad 1115 can be bonded to the inner side of the second clamping plate 11122 and the upper side of the third clamping plate 11123, so that after the fixing assembly 111 is fixedly installed on the edge 201 of the roof 200, the first isolation pad 1114 isolates the bottom of the first clamping plate 11112 of the first clamping part 1111 and the edge 201 of the roof 200, and the second isolation pad 1115 isolates the inner side of the second clamping plate 11122 of the second clamping part 1112 and the edge 201 of the roof 200, and isolates the upper side of the third clamping plate 11123 and the edge 201 of the roof 200, so as to achieve the purpose of protecting the edge 201 of the roof 200.

[0060] It is worth mentioning that the specific materials of the first isolation pad 1114 and the second isolation pad 1115 are not limited in the roof rack 100 of the present invention. For example, in a specific example of the roof rack 100 of the present invention, the first isolation pad 1114 and the second isolation pad 1115 can be a slightly elastic silicone material or a rubber material.

[0061] Continue to refer to the attached Figures 8 to 17 The base unit 11 further includes a bottom shell 113 having a bottom shell cavity 1131. The first clamping portion 1111 of the fixing assembly 111 is mounted on the bottom shell 113, and the fixing assembly 111 is accommodated in the bottom shell cavity 1131 of the bottom shell 113, so that the fixing assembly 111 is covered by the bottom shell 113. In this way, the bottom shell 113 makes the fixing assembly 111 invisible to the naked eye. The locking arm 112 is held above the bottom shell 113. For example, the bottom shell 113 has a bottom shell groove 1132. The bottom shell groove 1132 is connected to the bottom shell cavity 1131 at the top of the bottom shell 113, and the locking arm 112 extends to the top of the bottom shell 113 through the bottom shell groove 1132 of the bottom shell 113.

[0062] It is worth mentioning that the specific manner in which the first clamping portion 1111 is mounted on the bottom shell 113 is not limited in the roof rack 100 of the present invention. For example, in a specific example of the roof rack 100 of the present invention, refer to the attached Figure 11 and Figure 12 The first clamping portion 1111 includes at least one assembly arm 11113, and the assembly arm 11113 has an assembly hole 111130. The fixing component 111 further includes at least one second screw-mounted element 1116, and the second screw-mounted element 1116 can be a screw, wherein the screw-mounted end of the second screw-mounted element 1116 passes through the assembly hole 111130 of the assembly arm 11113 and is screwed to the bottom shell 113 to install the first clamping portion 1111 on the bottom shell 113.

[0063] In the attached Figures 1 to 22 In the illustrated embodiment of the roof rack 100 of the present invention, the first clamping portion 1111 includes two mounting arms 11113, one of which is provided on opposite sides of the locking arm 112. Accordingly, the fixing assembly 111 includes two second screwing elements 1116. The screwing end of each second screwing element 1116 passes through the mounting hole 111130 of each mounting arm 11113 and is then screwed onto the bottom shell 113, thereby securely securing the first clamping portion 1111 to the bottom shell 113. It will be appreciated that because the second screwing elements 1116 secure the second clamping portion 1112 to the first clamping portion 1111, the fixing assembly 111 can be housed within the bottom shell cavity 1131 of the bottom shell 113, rendering the fixing assembly 111 invisible.

[0064] Further, please refer to the attached Figure 9 、 Figure 11 and Figure 12 The locking arm 112 has a locking arm hole 1122, and the fixing assembly 111 further includes a third screw-mounted element 1117, which can be a screw, wherein the screw-mounted end of the third screw-mounted element 1117 passes through the locking arm hole 1122 of the locking arm 112 and is screwed to the bottom shell 113 to install the locking arm 112 on the bottom shell 113. It can be understood that since the first clamping portion 1111 and the locking arm 112 are the same sheet metal part, the second screw-mounted element 1116 and the third screw-mounted element 1117 can cooperate with each other to reliably install the fixing assembly 111 and the bottom shell 113.

[0065] Reference Attachment Figures 20 to 22The lock pin 123 has a guide slot 1233 and a positioning slot 1234. The guide slot 1233 extends along the length of the lock pin 123, and the positioning slot 1234 extends along the circumference of the lock pin 123. The positioning slot 1234 communicates with the guide slot 1233 at the end of the guide slot 1233 adjacent to the operating end 1232 of the lock pin 123. The lock unit 12 further includes a positioning post 124 disposed on the lock body 122 and projecting toward the lock pin hole 1221 of the lock body 122. The end of the positioning post 124 projecting toward the lock pin hole 1221 of the lock body 122 extends into the guide slot 1233 of the lock pin 123 and is allowed to slide from the guide slot 1233 of the lock pin 123 into the positioning slot 1234.

[0066] When the locking device 10 is in the locked state, the end of the positioning column 124 protruding toward the lock pin hole 1221 of the lock body 122 is retained in the positioning groove 1234 of the lock pin 123. At this time, the positioning column 124 and the lock pin 123 cooperate with each other to prevent the lock pin 123 from moving in the lock pin hole 1221 of the lock body 122, so that the locking end 1231 of the lock pin 123 is reliably maintained in the state of being inserted into the locking hole 1121 of the lock arm 112. After driving the lock pin 123 to rotate in the lock pin hole 1221 of the lock body 122, the end of the positioning column 124 protruding toward the lock pin hole 1221 of the lock body 122 slides from the positioning groove 1234 of the lock pin 123 into the guide groove 1233 to allow the lock pin 123 to move in the lock pin hole 1221 of the lock body 122. After the movement, the locking end 1231 of the lock pin 123 can be disengaged from the locking hole 1121 of the locking arm 112, so that the locking device 10 switches from the locked state to the unlocked state.

[0067] In addition, the locking device 10 of the present invention extends the end of the positioning column 124 protruding toward the lock pin hole 1221 of the lock body 122 to the guide groove 1233 and the positioning groove 1234 of the lock pin 123. On the one hand, when the lock pin 123 is not rotated, the end of the positioning column 124 protruding toward the lock pin hole 1221 of the lock body 122 can be reliably retained in the positioning groove 1234 of the lock pin 123, so that the locking device 10 is reliably maintained in the locked state. On the other hand, in the process of rotating the lock pin 123 and pulling the lock pin 123 to move in the lock pin hole 1221 of the lock body 122, the end of the positioning column 124 protruding toward the lock pin hole 1221 of the lock body 122 can prevent the lock pin 123 from disengaging from the lock body 122.

[0068] In a specific example of the roof rack 100 of the present invention, refer to the attached Figure 11 、 Figure 12 、 Figure 13 and Figure 17 The lock body 122 has a column assembly hole 1223, the extension direction of the column assembly hole 1223 and the extension direction of the lock pin hole 1221 are perpendicular to each other, and the column assembly hole 1223 communicates with the lock pin hole 1221 and the outside. After the lock pin 123 is inserted into the lock pin hole 1221 of the lock body 122 and the position of the guide groove 1233 or the positioning groove 1234 of the lock pin 123 corresponds to the position of the column assembly hole 1223 of the lock body 122, the positioning column 124 is assembled to the column assembly hole 1223 of the lock body 122, and the end of the positioning column 124 protruding toward the lock pin hole 1221 of the lock body 122 is allowed to extend to the guide groove 1233 or the positioning groove 1234 of the lock pin 123. Preferably, the inner wall of the column assembly hole 1223 of the lock body 122 has an internal thread structure, and the outer wall of the positioning column 124 has an external thread structure, and the two cooperate with each other to screw the positioning column 124 into the column assembly hole 1223 of the lock body 122. In this way, the positioning column 124 is prevented from falling from the column assembly hole 1223 of the lock body 122, thereby ensuring the reliability and stability of the locking device 10.

[0069] In one example of the roof rack 100 of the present invention, refer to the attached Figure 11 、 Figure 12 、 Figures 16 to 22The lock unit 12 further includes a return spring 125, which is sleeved on the lock pin 123, and the return spring 125 is constructed so that one end of the return spring 125 remains in a position relative to the lock body 122 and the other end of the return spring 125 remains in a position relative to the lock pin 123. When the lock pin 123 is driven to rotate in the lock pin hole 1221 of the lock body 122 so that the end of the positioning column 124 protruding toward the lock pin hole 1221 of the lock body 122 slides from the positioning groove 1234 of the lock pin 123 into the guide groove 1233, the return spring 125 is deformed in the circumferential direction to accumulate elastic potential energy. This elastic potential energy enables the return spring 125 to have a tendency to cause the lock pin 123 to rotate in the opposite direction in the lock pin hole 1221 of the lock body 122 so that the end of the positioning column 124 protruding toward the lock pin hole 1221 of the lock body 122 slides from the guide groove 1233 of the lock pin 123 into the positioning groove 1234. When the lock pin 123 is driven to move in the lock pin hole 1221 of the lock body 122 and the locking end 1231 of the lock pin 123 is disengaged from the locking hole 1121 of the lock arm 112, the return spring 125 is deformed in the length direction to accumulate elastic potential energy. This elastic potential energy enables the return spring 125 to have a tendency to cause the lock pin 123 to move in the opposite direction in the lock pin hole 1221 of the lock body 122 and cause the locking end 1231 of the lock pin 123 to be inserted into the locking hole 1121 of the lock arm 112.

[0070] In a specific example of the roof rack 100 of the present invention, refer to the attached Figure 18 and Figure 19 The lock pin 123 has an insertion hole 1235, and one end of the return spring 125 is inserted into the insertion hole 1235 of the lock pin 123, so that the position of the end of the return spring 125 relative to the lock pin 123 remains unchanged, and the lock body 122 has an insertion groove 1224, and the other end of the return spring 125 is inserted into the insertion groove 1224 of the lock body 122, so that the position of the end of the return spring 125 relative to the lock body 122 remains unchanged.

[0071] In one example of the roof rack 100 of the present invention, refer to the attached Figure 11 、 Figure 12 、 Figure 16 and Figure 17The lock unit 12 includes an annular plug 126 that is movably mounted on the operating end 1232 of the lock pin 123. The plug 126 is also installed in the lock pin hole 1221 of the lock body 122 to prevent the end of the return spring 125 from falling out of the insertion slot 1224 of the lock body 122. When the lock pin 123 is pulled, allowing the locking end 1231 of the lock pin 123 to move away from the locking hole 1121 of the lock arm 112, the lock pin 123 compresses the return spring 125 toward the plug 126, causing the return spring 125 to accumulate elastic potential energy.

[0072] It is worth noting that the specific manner in which the plug 126 is mounted in the lock pin hole 1221 of the lock body 122 is not limited in the roof rack 100 of the present invention. For example, in this specific example of the roof rack 100 of the present invention, the inner wall of the lock body 122 forming the lock pin hole 1221 has an internal thread structure, and the plug 126 has an external thread structure, and the two cooperate to screw the plug 126 into the lock pin hole 1221 of the lock body 122.

[0073] In one example of the roof rack 100 of the present invention, refer to the attached Figures 11 to 13 、 Figure 17 、 Figures 20 to 22The locking unit 12 includes a ball plunger 127, which includes a column portion 1271, a compression spring 1272 and a ball head portion 1273. The column portion 1271 has a column cavity 12711 and a cavity opening 12712 connected to the column cavity 12711. The compression spring 1272 is compressibly arranged in the column cavity 12711 of the column portion 1271. The ball head portion 1273 is movably arranged in the cavity opening 12712 of the column portion 1271, and the bottom of the ball head portion 1273 abuts against the compression spring 1272, and the top of the ball head portion 1273 protrudes from the column portion 1271. The cylindrical portion 1271 of the ball plunger 127 is disposed on the lock body 122, and the ball portion 1273 protrudes toward the lock pin hole 1221 of the lock body 122. The lock pin 123 has a retaining groove 1236. When the locking device 10 is in the locked state, the ball portion 1273 of the ball plunger 127 abuts against the peripheral wall of the lock pin 123. When the locking device 10 switches from the locked state to the unlocked state, the ball portion 1273 of the ball plunger 127 slides into the retaining groove 1236 of the lock pin 123. The friction force generated between the ball portion 1273 of the ball plunger 127 and the portion of the peripheral wall of the lock pin 123 forming the retaining groove 1236 causes the ball plunger 127 to position the lock pin 123, thereby maintaining the locking device 10 in the unlocked state.

[0074] In a specific example of the roof rack 100 of the present invention, refer to the attached Figure 17 The lock body 122 has a plunger assembly hole 1225. The extension direction of the plunger assembly hole 1225 and the extension direction of the lock pin hole 1221 are perpendicular to each other, and the plunger assembly hole 1225 communicates with the lock pin hole 1221 and the outside. The column portion 1271 of the ball plunger 127 is assembled in the plunger assembly hole 1225 of the lock body 122. Preferably, the inner wall of the plunger assembly hole 1225 of the lock body 122 has an internal thread structure, and the outer wall of the column portion 1271 of the ball plunger 127 has an external thread structure. The two cooperate with each other to screw the column portion 1271 of the ball plunger 127 into the plunger assembly hole 1225 of the lock body 122. In this way, the ball plunger 127 is prevented from falling out of the plunger assembly hole 1225 of the lock body 122, thereby ensuring the reliability and stability of the locking device 10.

[0075] In one example of the roof rack 100 of the present invention, refer to the attached Figure 12 、 Figure 16 and Figure 17The lock body 122 has a receiving hole 1226, and the receiving hole 1226 is connected to the insertion slot 1222. The position of the receiving hole 1226 corresponds to the position of the lock pin hole 1221, wherein the locking end 1231 of the lock pin 123 extends to the receiving hole 1226 of the lock body 122 after passing through the locking hole 1121 of the lock arm 112. In this way, on the one hand, when the locking device 10 switches from the unlocked state to the locked state, the locking device 10 can avoid the locking pin 123 from being locked. The stop end 1231 collides with the lock body 122 after passing through the locking hole 1121 of the locking arm 112, that is, the receiving hole 1226 of the lock body 122 can avoid the locking end 1231 of the locking pin 123. On the other hand, after the locking end 1231 of the locking pin 123 passes through the locking hole 1121 of the locking arm 112, the end of the locking end 1231 of the locking pin 123 can be retained in the receiving hole 1226 of the lock body 122, so that the base unit 11 and the lock unit 12 can be stably locked.

[0076] In one example of the roof rack 100 of the present invention, refer to the attached Figure 11 、 Figure 12 、 Figure 16 、 Figure 17 、 Figures 20 to 22 The base unit 11 further includes a protective pad 114, which includes a pad body 1141. The pad body 1141 has a pad through hole 11411. The pad body 1141 is disposed on the side of the locking arm 112 facing the locking pin hole 1221 of the lock body 122, and the pad through hole 11411 of the pad body 1141 is in communication with the locking hole 1121 of the locking arm 112. When the locking device 10 is in the unlocked state and the lock unit 12 moves relative to the base unit 11, the pad body 1141 can prevent the locking end 1231 of the locking pin 123 from scratching the locking arm 112. This not only protects the locking arm 112 and the locking pin 123, but also reduces noise, thereby improving the quality of the locking device 10.

[0077] It is worth noting that the specific manner in which the pad body 1141 is disposed on the side of the locking arm 112 is not limited in the roof rack 100 of the present invention. For example, in one specific embodiment of the roof rack 100 of the present invention, glue may be used to attach the pad body 1141 to the side of the locking arm 112. In another specific embodiment of the roof rack 100 of the present invention, rivets or screws may be used to attach the pad body 1141 to the side of the locking arm 112.

[0078] In a specific example of the roof rack 100 of the present invention, continue to refer to the attached Figure 11 、 Figure 12 、 Figure 16 、 Figure 17 、 Figures 20 to 22 The protective pad 114 further includes an isolation ring 1142 that extends from the pad body 1141 to the locking hole 1121 of the locking arm 112. When the locking end 1231 of the locking pin 123 is inserted into the locking hole 1121 of the locking arm 112, and the locking device 10 is in the locked state, the isolation ring 1142 isolates the locking pin 123 from the lock body 122. During vehicle operation, the isolation ring 1142 of the protective pad 114 prevents the locking pin 123 from colliding with the lock body 122, thereby ensuring the reliability of the locking device 10 and reducing noise, thereby improving the quality of the locking device 10.

[0079] It is worth noting that the specific material of the protective pad 114 is not limited in the roof rack 100 of the present invention, as long as it is wear-resistant and impact-resistant. For example, in a specific embodiment of the roof rack 100 of the present invention, the protective pad 114 can be a one-piece structure made of rubber material.

[0080] In a specific example of the roof rack 100 of the present invention, continue to refer to the attached Figure 11 、 Figures 20 to 22 The pad body 1141 has a guide groove 11412, which is connected to the pad body through hole 11411, and the guide groove 1142 is "V"-shaped, wherein the pad body 1141 can guide the locking end 1231 of the locking pin 123 to reach the position corresponding to the pad body through hole 11411 of the pad body 1141, so that the locking end 1231 of the locking pin 123 can be smoothly inserted into the locking hole 1121 of the locking arm 112.

[0081] In one example of the roof rack 100 of the present invention, refer to the attached Figures 8 to 17The housing 121 of the lock unit 12 has a housing space 1211 and a bottom slot 1212 and a side through-hole 1213 connected to the housing space 1211. The lock body 122 is fixedly mounted on the housing 121 and accommodated in the housing space 1211 of the housing 121. The position of the insertion slot 1222 of the lock body 122 corresponds to the position of the bottom slot 1212 of the housing 121. The lock arm 112 is allowed to pass through the housing. The bottom slot 1212 of the shell 121 is inserted into the insertion slot 1222 of the lock body 122, and the position of the lock pin hole 1221 of the lock body 122 corresponds to the position of the side through hole 1213 of the shell 121. The operating end 1232 of the lock pin 123 extends to the outside of the shell 121 through the side through hole 1213 of the shell 121, so that the user can operate the operating end 1232 of the lock pin 123 outside the locking device 10.

[0082] In a specific example of the roof rack 100 of the present invention, refer to the attached Figure 11 and Figure 12 The outer shell 121 includes an outer shell 1214 and an inner shell 1215. The outer shell 1214 and the inner shell 1215 are installed with each other to form the shell space 1211, the bottom groove 1212 and the side through-hole 1213 between the outer shell 1214 and the inner shell 1215.

[0083] It is worth mentioning that the installation method of the outer shell 1214 and the inner shell 1215 is not limited in the roof rack 100 of the present invention. For example, in a specific example of the roof luggage rack 100 of the present invention, the inner shell 1215 has at least two shell through-holes 12151, and the lock unit 12 further includes at least two fourth screw-mounted elements 128, which can be screws, wherein the screw-mounted end of at least one of the fourth screw-mounted elements 128 is screwed onto the lock body 122 after passing through the shell through-holes 12151 of the inner shell 1215, so as to fixedly install the lock body 122 on the outer shell 121 and enable the lock body 122 to be reliably accommodated in the shell space 1211 of the outer shell 121, wherein the screw-mounted end of at least one of the fourth screw-mounted elements 128 is screwed onto the outer shell 1214 after passing through the shell through-holes 12151 of the inner shell 1215, so as to reliably install the outer shell 1214 and the inner shell 1215.

[0084] Preferably, the outer shell 1214 has at least one insertion groove 12140, and the inner shell 1215 has at least one insertion protrusion 12150, and the insertion protrusion 12150 of the inner shell 1215 is inserted into the insertion groove 12140 of the outer shell 1214 to increase the reliability of the installation relationship between the outer shell 1214 and the inner shell 1215.

[0085] In one example of the roof rack 100 of the present invention, refer to the attached Figures 8 to 12 、 Figure 16 and Figure 17 The lock unit 12 includes an operating knob 129 , which is fixedly mounted on the operating end 1232 of the lock pin 123 . The user can conveniently rotate and move the lock pin 123 through the operating knob 129 .

[0086] Reference Attachment Figures 5 to 7 The roof rack 100 further includes at least one longitudinal beam 30, and each of the opposite ends of the longitudinal beam 30 is provided with a locking device 10. The longitudinal beam 30 is fixedly mounted on the luggage rack 20, and the opposite ends of the longitudinal beam 30 extend to the opposite sides of the luggage rack 20, so that each of the opposite sides of the luggage rack 20 is provided with at least one locking device 10.

[0087] In a specific example of the roof rack 100 of the present invention, the roof rack 100 includes two longitudinal beams 30, one longitudinal beam 30 is fixedly mounted on the front end of the luggage rack 20, and the other longitudinal beam 30 is fixedly mounted on the rear end of the luggage rack 20. In this way, two locking devices 10 are respectively provided on opposite sides of the luggage rack 20, so that the roof rack 100 can be securely mounted on the roof 200.

[0088] Reference Attachment Figure 7 The roof rack 100 further includes at least two pressing pieces 40, which are mounted on the outer shell 121 of the locking unit 12 of the locking device 10, wherein a portion of the end of the longitudinal beam 30 is clamped between the pressing piece 40 and the outer shell 121 to set the locking device 10 at the end of the longitudinal beam 30.

[0089] It is worth mentioning that the specific manner of mounting the pressing piece 40 on the housing 121 is not limited in the roof rack 100 of the present invention. For example, in this specific example of the roof rack 100 of the present invention, refer to the attached Figure 7The outer shell 121 has at least one outer shell through-hole 1216, the pressing plate 40 has at least one pressing plate through-hole 41, and the roof rack 100 includes at least one fifth screw-mounted element 50, which can be a screw, wherein the screw-mounted end of the fifth screw-mounted element 50 passes through the outer shell through-hole 1216 of the outer shell 121 and the pressing plate through-hole of the pressing plate 40, and is screwed onto the inner wall of the pressing plate 40 for forming the pressing plate through-hole 41, so that the pressing plate 40 and the outer shell 121 can reliably clamp a portion of the end of the longitudinal beam 30, thereby reliably setting the locking device 10 at the end of the longitudinal beam 30.

[0090] Continue to refer to the attached Figure 7 The longitudinal beam 30 includes a main body 31, a longitudinal arm 32 integrally extending from the side of the main body 31, and a transverse arm 33 integrally extending from the bottom of the longitudinal arm 32. The pressing piece 40 and the shell 121 clamp the transverse arm 33 of the longitudinal beam 30 to reliably set the locking device 10 at the end of the longitudinal beam 30 and hide the pressing piece 40.

[0091] When the roof 200 of the vehicle does not need to be cleaned, the locking device 10 is in the locked state. The locking device 10 is used to reliably maintain the luggage rack 20 above the roof 200 and to create a gap between the luggage rack 20 and the roof 200 to prevent the luggage rack 20 from directly contacting the roof 200, thereby protecting the roof 200.

[0092] When the roof 200 of the vehicle needs to be cleaned, first, the locking pin 123 is driven to rotate in the locking pin hole 1221 of the lock body 122 by the operating knob 129, so that the end of the positioning column 124 protruding from the locking pin hole 1221 of the lock body 122 slides into the positioning groove 1234 of the locking pin 123 from the guiding groove 1233. In this process, the return spring 125 is deformed in the circumferential direction to accumulate elastic potential energy. Secondly, the locking pin 123 is pulled in the locking pin hole 1221 of the lock body 122 by the operating knob 129, so that the locking end 1231 of the locking pin 123 is disengaged from the locking hole 1121 of the locking arm 112. In this process, the return spring 125 is deformed in the length direction to accumulate elastic potential energy, and at this time, the locking device 10 switches from the locked state to the unlocked state. When the locking device 10 switches from the locked state to the unlocked state, the ball portion 1273 of the ball plunger 127 slides into the retaining groove 1236 of the lock pin 123. The friction generated between the ball portion 1273 of the ball plunger 127 and the portion of the peripheral wall of the lock pin 123 that forms the retaining groove 1236 causes the ball plunger 127 to position the lock pin 123, thereby maintaining the locking device 10 in the unlocked state. Similarly, another locking device 10 located on the same side of the luggage rack 20 can also switch from the locked state to the unlocked state.

[0093] After the two locking devices 10 located on the same side of the luggage rack 20 are in the unlocked state, the luggage rack 20 is pushed upward, and the luggage rack 20 rotates around the locking pins 123 of the locking units 12 of the two locking devices 10 on the other side to increase the gap between the luggage rack 20 and the roof 200, thereby facilitating cleaning of the roof 200.

[0094] After the roof 200 is cleaned, the luggage rack 20 automatically falls down due to its own weight, allowing the locking arm 112 of the base unit 11 of the locking device 10 to be inserted into the insertion groove 1222 of the lock body 122 of the lock unit 12. When the locking pin 123 is pushed by the operating knob 129, and the thrust is greater than the ball head portion 1273 of the ball plunger 127 and the peripheral wall of the locking pin 123 for forming the retaining groove 1236, the luggage rack 20 automatically falls down due to its own weight, allowing the locking arm 112 of the base unit 11 of the locking device 10 to be inserted into the insertion groove 1222 of the lock body 122 of the lock unit 12. When the friction force between the parts is generated, the return spring 125 causes the locking end 1231 of the lock pin 123 to be inserted into the locking hole 1121 of the lock arm 112 during the process of returning to the initial state, and causes the end of the positioning column 124 protruding toward the lock pin hole 1221 of the lock body 122 to slide from the guide groove 1233 of the lock pin 123 into the positioning groove 1234, so that the locking device 10 switches from the unlocked state to the locked state and maintains in the locked state.

[0095] In other words, the lock unit 12 and the base unit 11 of the locking device 10 can be separated by hand without the use of any tools. This is crucial for exposing the roof 200 by separating the lock unit 12 and the base unit 11 so as to facilitate cleaning of the roof 200. Furthermore, after cleaning the roof 200, the lock unit 12 and the base unit 11 can be re-locked by hand to securely secure the luggage rack 20 to the vehicle 20. This is crucial for exposing the roof 200 by separating the lock unit 12 and the base unit 11 so as to facilitate cleaning of the roof 200 and for driving safety.

[0096] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed herein are intended to be covered by the claims of the present invention.
