Description

Locking device for automobile roof box {LOCKING DEVICE FOR VEHICLE ROOF BOX}

The present invention relates to a roof box that is fixedly installed on the roof rail of a car roof and used as a loading space, and more specifically, to a locking device for a car roof box that can easily open and close the roof box.

The roof box is installed on the roof of a vehicle with roof rails installed and is used to expand the loading space other than the trunk. It is mainly made in the form of a box made of plastic and fabric and is loaded inside, so stored items are not exposed to sunlight, rainwater, blowing in the wind, and damage can be prevented. The trunk loading space can be expanded by using the roof box.

There are two roof rails installed vertically on the roof of the vehicle for use in loading or securing luggage. A separate carrier can be installed to load or secure leisure sports equipment such as bicycles, boards, and skis. The roof box is used by being fixed to the roof of the vehicle using these roof rails.

The roof box consists of a container that holds goods and a cover that covers the container like a lid. The container and the cover are combined using a hinge axis to open and close the container, which is a loading space, by lifting or lowering the cover from the container. .

In other words, when the cover is lifted, the storage compartment, which is a loading space, opens, and when the cover is pushed down, the storage compartment closes. Since the cover is heavy to lift by manpower, a hinge device using a shock absorber near the hinge axis is used to lift the cover. Install to open and close easily.

However, the roof box is equipped with a locking device to safely store items stored in the container or to prevent the cover from opening while driving, and opening and closing the locking device simply and quickly is very important in utilizing the roof box.

In this way, various locking devices are being developed to make opening and closing the roof box lock simple, easy, and quick. However, as the structure becomes simpler, the function becomes simpler, making it inconvenient to use, and as functionality increases, the structure becomes more complex, increasing production costs. Product defects, such as breakdowns during use, frequently occur.

Republic of Korea Patent No. 10-2202682 Republic of Korea Patent Publication No. 10-2019-43256

The present invention is intended to solve the problems described above. When the cover is closed, it is automatically closed by the movable pin only by the weight of the cover without the need to operate the key in the keychain, and when it is opened, it is retracted by simply pulling the control pin with a simple key operation. It is a locking device for automobile roof boxes that allows simple and smooth operation by returning and locking by a movable pin while expanding the locking distance of the locking bracket to prevent malfunction even if eccentricity occurs during use. We would like to provide.

In order to achieve the above object, the present invention includes a pair of pin fixing plates coupled to the inner wall of the roof box accommodating box and formed facing each other, a ring insert formed on one side of the pin fixing plate to face each other, and a ring insert formed by connecting the pin fixing plates. movable pin shaft; An adjustment pin shaft formed while connecting the pin fixing plates; a movable pin rotatably coupled to the movable pin shaft and formed of a long pin on one side and a short pin whose length is relatively shorter than the long pin, and a pinch groove formed on the other side; It is rotatably formed on the control pin shaft, and on one side, a pinch is formed that abuts the pinch groove to prevent or rotate the movable pin depending on the amount of rotation, and on one side, an adjustment pin connected to the wire of the key bundle; A reverse rotation spring that has one end fixed to the movable pin shaft and partially wound, and the other end fixed to the control pin shaft and the other part wound, so that the movable pin shaft and the control pin shaft generate rotational force in only one direction while being in opposite directions. ; A stopper formed at an upper end of one side of the pin fixing plate to stop the rotation of the movable pin at a specific angle without further rotation; A key bundle having a spring hinge pin and a load hinge pin that operate in opposite directions when a key is inserted into the key hole of the key bundle and turned, and the load hinge pin is connected to an adjustment pin through a wire; One end is coupled to one side of the receiving box, and the other end is coupled to the spring hinge pin of the key bundle to elastically support the load hinge pin and the spring hinge pin, so that when the key is inserted into the key hole of the key bundle and turned, the load hinge pin and A tension spring that pulls the adjustment pin while allowing the spring hinge pin to shorten its length, and when the turned key is released, the load hinge pin and the spring hinge pin are returned by a restoring force and lengthened to return the adjustment pin to its original position. Provided is a locking device for an automobile roof box, characterized in that it is made up of the following.

According to the present invention, the length of the short pin of the processing pin is about 4 to 6 mm shorter than the long pin, so the operating space of the ring groove (V) is not relatively narrow even when the movable pin is inclined at about 60°. Since the operating space is not narrowed, the width (space) of the ring groove (V) can be made relatively small.

In addition, the longer the short pin, the more the movable pin must be rotated for the short pin to come out of the lock ring when releasing the locking device, so the size of the locking device has to be increased correspondingly. The locking device and locking bracket attached to the roof box's storage box and the inner wall of the cover reduce the usability of the space inside the roof box due to interference with objects during use, so the smaller the design, the more advantageous it is. In other words, if the size of the movable pin can be reduced, it is advantageous to reduce the size of the locking device, so the presence or absence of short pins with a relatively smaller length than long pins also plays an important role in reducing the size of the locking device.

The present invention will be described in detail with reference to the attached drawings as follows.

As shown in Figures 1 and 2, the roof of the car consists of a housing (H) and a cover (C) covering the housing, and the cover is secured by a hinge device installed between the housing (H) and the cover (C). A roof box that can be opened and closed is installed.

As shown in Figures 3 and 4, the inner walls on both sides of the receiving box (H) of the roof box are integrally formed by the bottom plate (112) and are spaced apart by the width of the bottom plate (P) at both ends of the bottom plate (P). A pair of pin fixing plates 110 that are formed vertically and face each other are coupled.

A ring insertion hole 112 is formed opposite to one side of the pin fixing plate 110. The ring insertion hole 112 is where the locking ring 192 of the locking bracket 190 coupled to the cover (C) is inserted. The upper side is formed to be wider than the lower side, so that the locking device 100 is installed during the installation process. Even if (100) or the cover has an installation error or is slightly eccentric, the locking ring (192) is accurately guided and allowed to flow in.

A movable pin shaft 130 and an adjustable pin shaft 140 are formed on the other side of the pin fixing plate 110. The movable pin shaft 130 and the control pin shaft 140 are formed parallel to each other while connecting the pin fixing plate 110.

The movable pin shaft 130 is formed close to the ring insertion hole 112, and the control pin shaft 140 is spaced apart from the movable pin shaft 130 and is formed at a position about 2 to 3 mm lower than the movable pin shaft 130. The separation distance between the movable pin shaft 130 and the control pin shaft 140 is about 7 to 10 mm, which ensures the operating distance of the movable pin 150 and the control pin 160, which will be described later.

A movable pin 150 is inserted into the movable pin shaft 130 and rotatably coupled thereto. A shaft hole is formed in the movable pin 150, so that the shaft hole is inserted into the movable pin shaft 130 and can freely rotate around the movable pin shaft 130.

A long pin 152 and a short pin 154 are formed on the movable pin 150, and a ring guide groove 158 through which a locking ring passes is formed between the long pin 152 and the short pin 154. A pinch groove 156 is formed on one side of the movable pin 150.

The control pin 160 is inserted into the control pin shaft 140 and rotatably coupled thereto. Since an axial hole is formed in the control pin, the axial hole is inserted into the control pin shaft 140 and can rotate about the roughening pin shaft 140. A pinch 162 is formed on one side of the control pin 160 to abut against the pinch groove 156 of the movable pin 150.

A reverse rotation spring 170 is installed on the movable pin shaft 130 and the control pin shaft 140. One end of the reverse rotation spring 170 is connected to one side of the movable pin 150, and a portion is wound around the movable pin shaft 130 so that elastic reverse rotation always occurs when the movable pin 150 is rotated by an external force. And, the other end is connected to one side of the control pin 160, and a part is wound around the control pin shaft 140 so that elastic reverse rotation always occurs when the control pin 160 is rotated by an external force. That is, one reverse rotation spring 170_ allows elastic reverse rotation to occur simultaneously in the movable pin 150 and the control pin 160.

As shown in FIGS. 5A, 5B, 6A, and 6B, the movable pin 150 is elastically supported in a counterclockwise direction and the control pin 160 is elastically supported in a clockwise direction to generate a rotational force in the reverse rotation spring 170. There is a stopper 180 formed on the upper part of the pin fixing plate 110 to limit the rotation amount of the movable pin 150. The movable pin 150 is limited to no longer rotate in a state inclined at approximately 60° with respect to the base plate unless an external force is applied. The pinch 162 of the control pin 160 is in close contact with the outer surface of the movable pin 150, and when the movable pin 150 is rotated by an external force and becomes horizontal with the base plate 112, the pinch 162 is pinched. It momentarily slides into the groove 156 and engages so that it does not rotate counterclockwise even if the external force applied to the movable pin 150 is removed.

The width of the bottom plate (P) is designed by calculating the protrusion of the locking bracket 190 coupled to the inner wall of the cover (C), and the lengths of the movable pin shaft 130 and the adjusting pin shaft 140 are also designed by calculating the protrusion of the locking bracket 190 coupled to the inner wall of the cover (C). Since the width (distance between the pin fixing plate and the pin fixing plate) is the same, the movable pin 150 and the control pin 160 are inserted into the movable pin shaft 130 and the control pin shaft 140, and the reverse rotation spring 170 is outside them. Even when installed, space remains. When the reverse rotation spring 170 is installed on the movable pin shaft 130 and the control pin shaft 140 and space remains, the reverse rotation spring 170 is connected to the movable pin 150 and the movable pin shaft 130 and the control pin shaft 140. When the control pin 160 operates, it may move back and forth. Therefore, in order to prevent this movement, the spring key 172, which prevents the reverse rotation spring 170 from moving along the movable pin axis 130 and the control pin axis 140 on one side, is installed on the movable pin axis 130 and the control pin axis 140. ) are fixed to each.

The spring key 172 can be moved in the axial direction as needed on the movable pin shaft 130 and the control pin shaft 140 by using a tool called key pliers. This is done by assembling the reversing spring 170 to the movable pin shaft 130 and the adjusting pin shaft 140, inserting the spring key 172, and pushing it toward the reversing spring 170 to connect the spring key 172 and the reversing spring 170. ) is very useful in minimizing the axial movement of the movable pin 150 and the control pin 160 by ensuring that they are in as close contact as possible. In other words, if the spring key 172 is inserted into the keyway after forming the keyway using a general machining method, the spring key 172 becomes stuck in the keyway after assembly and cannot move at all in the axial direction, thereby preventing this problem.

In the present invention, the long pin 152 and the short pin 154 of the movable pin 150 have different lengths, which is very important in designing the locking device 100 of the roof box.

The ring groove (V) between the long pin 152 and the short pin 154 is a space where the lock ring is inserted and locked when the locking device 100 is locked. The larger the width (space) of the ring groove (V), the larger the lock ring (192). ) is advantageous for insertion. Roof boxes are generally made of synthetic resin, and have the property of being momentarily deformed and then restored when an external force is applied. If the locking device 100 is manufactured precisely, the locking ring 192 can theoretically be inserted even if the width of the ring groove (V) is the same as the diameter of the locking ring 192, but the more precisely it is manufactured, the more it costs. Even if an assembly error occurs or the roof box or locking device 100 is slightly deformed during use, the locking ring 192 is not inserted into the ring groove (V) and cannot function properly.

Therefore, the width of the ring groove (V) must be larger than the diameter of the lock ring (192) to allow for free space, taking into account processing and assembly errors of the roof box or locking device (100) and deformation during use. However, if the free space is large, when the locking ring 192 is inserted into the ring groove (V) and locked, it moves within the space while the vehicle is running, causing it to rattle. Therefore, it is very important to reduce the width of the hook groove (V) and ensure that the locking ring 192 can be easily inserted into the hook groove (V) even if the roof box or locking device 100 is slightly deformed during use.

In this way, the difference in length between the long pin 152 and the short pin 154 of the movable pin 150 is due to the fact that when the locking ring 192 is inserted into the ring groove (V), the roof box or the locking device 100 is not used due to manufacturing errors or manufacturing errors. It plays a very important function in ensuring that the locking ring (192) is properly inserted into the ring groove (V) even if there are assembly errors or deformation during use.

The movable pin 150 is inclined about 60° from the bottom plate (P), so when the cover (C) comes down and closes, the locking ring 192 is the first to contact the inside of the long pin 152, and continues to go down in that state. When the movable pin 150 is level with the bottom plate (P), the pinch 162 is removed from the pinch groove 156, and the short pin 154 is inserted into the lock ring 192 and locked by reverse rotation of the movable pin 150. . Here, if the length of the long pin 152 and the short pin 154 are the same, the operating space of the ring groove (V) becomes narrower in proportion to the inclination.

Considering that the space of the ring groove (V) is narrowed, if the space of the ring groove (V) is enlarged, there is a lot of free space after the lock ring (192) is inserted, so it is bound to rattle even in the locked state, but in the present invention, a single pin ( 154) is about 4 to 6 mm shorter in length than the long pin 152, so the operating space of the ring groove (V) is not relatively narrow even when the movable pin 150 is inclined at 60°. Since the operating space is not narrowed, the width (space) of the ring groove (V) can be made relatively small.

In addition, the longer the length of the short pin 154, the more the movable pin 150 must be rotated so that the short pin 154 can come out of the lock ring 192 when releasing the locking device 100, so the locking device 100 The size of can't help but grow that much. The locking device 100 and locking bracket coupled to the inner walls of the roof box's storage box (H) and cover (C) reduce the usability of the space inside the roof box due to interference with objects during use, so it is more advantageous to design it smaller. That is, if the size of the movable pin 150 can be reduced, it is advantageous to reduce the size of the locking device 100. Therefore, the presence or absence of the short pin 154, which is relatively shorter than the long pin 152, helps reduce the size of the locking device 100. also plays an important role.

The operation of the present invention configured as described above will be described as follows.

As shown in FIGS. 5A, 5B, 6A, and 6B, when the cover (C) is pressed when the cover is to be closed, the cover (C) is lowered while being elastically supported by a spring built into the hinge device. The locking ring 192 of the locking bracket 190 coupled to the inner wall first contacts the long pin 152 of the movable pin 150.

When the descending locking ring 192 contacts the long pin 152, the long pin 152 is pressed and the long pin 152 rotates around the movable pin shaft 130 and moves down, and at this time, the short pin 154 is also rotated. .

When the movable pin 150 is rotated, the control pin 160, which was in contact with the movable pin 150, rotates together while rubbing against the movable pin 150, and when the long pin 152 is level with the bottom plate (P), the control pin 160 ) of the pinch 162 is momentarily inserted into the pinch groove 156 of the movable pin 150 and engaged with it, and the rotation of the movable pin 150 stops and is fixed in that state.

When the locking ring 192 continues to descend after contacting the long pin 152, the short pin 154 rotates and flows into the locking ring 192, and the long pin 152 is level with the bottom plate (P) and the movable pin 150 ) is fixed, the locking ring 192 is caught on the short pin 154 and cannot be opened even if the external force pressing the cover (C) is removed. In addition, the control pin 160 is supported to always rotate clockwise by the reverse rotation spring 170, and the pinch 162 of the control pin 160 is inserted into the pinch groove 156 of the movable pin 150. Therefore, unless a specific external force or more is applied, the movable pin 150 does not rotate clockwise and remains fixed. That is, the locking ring 192 is caught on the short pin 154, so that the cover C coupled with the locking ring 192 cannot be opened.

When you want to open the cover (C), insert the key into the key hole of the key bundle (210) and turn it, which pulls the load hinge pin (214) and pulls the control pin (160) connected through the wire (W). The locking device 100 is installed in two places on both sides of the inner wall of the receiving box (H), but is connected to the load hinge pin 214 through the connector (T) and wire (W), so the load hinge pin (214) When this is pulled, both control pins 160 of the locking device are pulled at the same time.

The control pin 160 is pulled, but as the control pin 160 rotates, the pinch 162 of the control pin 160 inserted into the pinch groove 156 of the movable pin 150 rubs against the pinch groove 156. It slides and rotates, and when the pinch 162 completely exits the pinch groove 156, the movable pin 150, which was elastically supported by the reverse rotation spring 170, is momentarily reversely rotated, and the single pin of the movable pin 150 ( 154) momentarily comes out of the lock ring (192).

When the short pin 154 of the movable pin 150 momentarily comes out of the locking ring 192, the cover (C) is elastically supported to always be upward by the hinge device, so it is immediately released from the locking device 100 and lifted upward to open. do.

Since the rotation of the movable pin 150 is limited by the stopper 180, the cover C is returned to its original state before being locked in the locking device 100. In this way, when the cover (C) is pressed, the locking ring (192) of the locking bracket (190) is caught by the short pin (154) of the movable pin (150) and locked, and when the key is inserted into the key hole of the key bundle and turned, the control pin (160) is locked. As it rotates, the pinch 162 is pulled out of the pinch groove 156, and the movable pin 150 is instantly rotated and unlocked. In addition, the cover (C) is elastically supported so that it is always upward by a hinge device, so when opening the cover (C), simply insert the key into the keyhole and turn it to automatically open.
