Description

Technical Field

[0001] The present application relates to the technical field of vehicle connection devices, and in particular to a connection device, a fixed bracket, a movable bracket, a vehicle-mounted device and a vehicle. Background Art

[0002] At present, seats are still the main onboard equipment in the cabin space of new energy vehicles. As the market share of new energy vehicles continues to increase, users have more and more demands for onboard equipment, and onboard equipment such as refrigerators, tables, beds, and kitchen equipment in RVs have emerged. However, current onboard equipment (such as seats) is fixed to the vehicle body with screws, which makes disassembly and assembly difficult and laborious. Ordinary people without professional training cannot disassemble and assemble it independently. Summary of the invention

[0003] The embodiments of the present application provide a connecting device, a fixed bracket, a movable bracket, a vehicle-mounted device and a vehicle, which are used to solve the technical problem of difficulty in disassembling and assembling the vehicle-mounted device.

[0004] In order to achieve the above objectives, this application adopts the following technical solutions:

[0005] In a first aspect of an embodiment of the present application, a connection device is provided, which includes a fixed bracket and a movable bracket. The fixed bracket includes a first bracket body and a first limiting member, and the first limiting member is connected to the first bracket body. The first limiting member includes a first clamping portion and two first limiting portions, and the two first limiting portions are arranged at intervals and connected to the first clamping portion. The movable bracket includes a second bracket body and a second limiting member, and the second limiting member is connected to the second bracket body. The second limiting member includes a second clamping portion and two second limiting portions, and the two second limiting portions are arranged at intervals and connected to the second clamping portion. Among them, the first clamping portion is clamped between the two second limiting portions, and the second clamping portion is clamped between the two first limiting portions.

[0006] As can be seen from the above, when the fixed bracket is connected to the movable bracket, since the first clamping part is connected to two first limiting parts arranged at intervals, and the second clamping part is connected to two second limiting parts arranged at intervals, the first clamping part can be clamped between the two second limiting parts, and the second clamping part can be clamped between the two first limiting parts. That is, the first limiting member and the second limiting member can be clamped to each other to form a "handshake" structure. In this way, the first limiting member and the second limiting member can be connected by a mutual clamping mode, which has a simple structure and convenient operation. At the same time, after the first limiting member and the second limiting member are connected, the first limiting member can limit the movement of the second clamping member between the two first limiting parts through the two first limiting parts, and the second limiting member can also limit the movement of the first clamping member between the two second limiting parts through the two second limiting parts. As a result, not only the function of connecting the fixed bracket to the movable bracket is realized, but also the fixed bracket and the movable bracket can be locked to each other in other directions different from the clamping direction, ensuring the stability of the connection between the fixed bracket and the movable bracket, thereby avoiding the problem of the vehicle-mounted equipment being unlocked under vehicle-mounted working conditions. Compared with the prior art method of fixing vehicle-mounted equipment with screws, the connection device provided in the embodiment of the present application does not require the screws to be removed and installed one by one, does not require the position of the screws to be found, and does not require the order of removing and installing the screws, thereby greatly reducing the difficulty of disassembling and installing the vehicle-mounted equipment.

[0007] In some embodiments, the first limit member further includes a first sliding block, and the first sliding block is connected to a side of the first clamping portion away from the first limit member. When the first clamping portion contacts the second clamping portion, there is a gap between the second limit member and the first sliding block. As a result, the first clamping portion and the second clamping portion can contact the first sliding block before the second limit member. When the connecting device is used for a long time and the first clamping portion and the second clamping portion are worn, the clamping fit between the first limit member and the second limit member can be compensated by the contact between the second limit member and the first sliding block, thereby ensuring the stability of the connection of the connecting device.

[0008] In some embodiments, a first guide angle is provided on the side of the first clamping portion facing the first limiting portion, and a second guide angle is provided on the side of the first limiting portion away from the first clamping portion. A third guide angle is provided on the side of the second clamping portion facing the second limiting portion, and a fourth guide angle is provided on the side of the second limiting portion away from the second clamping portion. Thus, the first guide angle on the first clamping portion can guide the clamping of the two second limiting portions, and the third guide angle on the second clamping portion can guide the clamping of the two first limiting portions. At the same time, the second guide angle on the first limiting portion and the fourth guide angle on the second limiting portion can guide the sliding of the first limiting member and the second limiting member to each other, thereby avoiding the first limiting member and the second limiting member from being stuck during the clamping process.

[0009] In some embodiments, the first clamping part is in interference fit with the two second limiting parts, and the second clamping part is in interference fit with the two first limiting parts. Thus, a gap between the first clamping part and the two second limiting parts can be avoided, and a gap between the second clamping part and the two first limiting parts can be avoided, thereby avoiding collision damage caused by shaking between the first limiting part and the second limiting part.

[0010] In some embodiments, the connection device further includes a first elastic pad layer and a second elastic pad layer. The first elastic pad layer is disposed between the first clamping portion and the second limiting portion, and the second elastic pad layer is disposed between the second clamping portion and the first limiting portion. Thus, by disposing the first elastic pad layer between the first clamping portion and the second limiting portion, and disposing the second elastic pad layer between the second clamping portion and the first limiting portion, collision damage caused by shaking between the first limiting member and the second limiting member can also be avoided.

[0011] In some embodiments, the fixed bracket further includes a third limiter, which is connected to the first bracket body. The third limiter includes a third clamping portion and two third limiters, which are arranged at intervals and connected to the third clamping portion. The third clamping portion is located on the side of the first clamping portion away from the two first limiters, and the two third limiters are located on the side of the third clamping portion away from the first clamping portion. The movable bracket further includes a fourth limiter, which is connected to the second bracket body. The fourth limiter includes a fourth clamping portion and two fourth limiters, which are arranged at intervals and connected to the fourth clamping portion. Among them, the third clamping portion is clamped between the two fourth limiters, and the fourth clamping portion is clamped between the two third limiters. As a result, the third limiter and the fourth limiter can also be clamped to each other to form a "handshake" structure, and the two sets of "handshake" clamping structures can improve the stability of the connection between the fixed bracket and the movable bracket. At the same time, since the third clamping portion is located on the side of the first clamping portion away from the two first limiting portions, and the two third limiting portions are located on the side of the third clamping portion away from the first clamping portion, the first limiting member can be clamped with the third limiting member in opposite directions, so that the fixed bracket and the movable bracket can be locked in opposite directions, thereby ensuring the reliability of the connecting device.

[0012] In some embodiments, the connection device further includes a telescopic device connected to the first bracket body. The telescopic device is connected between the first limiter and the third limiter, and the telescopic device drives the first limiter and the third limiter to move in a direction close to or away from each other. Thus, the telescopic device can drive the first limiter and the third limiter to move in opposite directions, so that the first limiter and the third limiter can be supported between the second limiter and the fourth limiter, so that the fixed bracket and the movable bracket can be locked in the telescopic direction of the telescopic device, and the connection device can be locked in three directions at the same time.

[0013] In some embodiments, the telescopic device includes a driving member and a bidirectional screw. The bidirectional screw includes a first screw thread portion and a second screw thread portion with opposite threads, the bidirectional screw is threadedly connected to the first limit member through the first screw thread portion, and the bidirectional screw is threadedly connected to the third limit member through the second screw thread portion. The bidirectional screw is connected to the driving member, and the driving member drives the bidirectional screw to rotate. Thus, when the driving member drives the bidirectional screw to rotate, since the threads of the first screw thread portion and the second screw thread portion are opposite, the first limit member and the third limit member can move synchronously in opposite directions, so that the first limit member and the third limit member can be engaged at the same time.

[0014] In some embodiments, the first screw thread portion and the first stopper are matched with a transmission thread, and the second screw thread portion and the third stopper are matched with a transmission thread. Thus, the transmission thread match has a self-locking function, which can prevent the first stopper and the third stopper from retracting on the bidirectional screw rod along the telescopic direction, thereby ensuring the reliability of the connection between the fixed bracket and the movable bracket.

[0015] In some embodiments, the fixed bracket further includes a switch button. The switch button is disposed on the first bracket body and is electrically connected to the driving member. Thus, the switch button is disposed so that the user can control the locking and unlocking functions between the fixed bracket and the movable bracket by clicking the switch button, thereby facilitating the user's operation and reducing the difficulty of disassembling and assembling the vehicle-mounted device.

[0016] In some embodiments, the fixed bracket further includes an electrical interface. The electrical interface is provided on the first bracket body and is electrically connected to the switch button and the driving member, respectively. Thus, the provision of the electrical interface enables the user to power the driving member and the switch button by connecting the external power supply to the electrical interface when the connecting device is powered off, thereby controlling the locking and unlocking functions between the fixed bracket and the movable bracket, thereby eliminating the need to frequently start and stop the vehicle.

[0017] In some embodiments, the first bracket body is provided with a first connection hole and a second connection hole which are arranged at intervals. The first bracket body is connected to the second bracket body, the second limiter is inserted into the first connection hole, and the fourth limiter is inserted into the second connection hole. Thus, the first bracket body and the second bracket body can be connected by inserting the second limiter into the first connection hole and the fourth limiter into the second connection hole, thereby realizing the function of connecting the fixed bracket and the movable bracket. Compared with the prior art, there is no need to disassemble and install the screws one by one, which reduces the difficulty of operating the connecting device.

[0018] In some embodiments, a cylindrical accommodating cavity is provided in the first bracket body, and the accommodating cavity is respectively connected to the first connecting hole and the second connecting hole. The first limiting member also includes a first sliding block, and the first sliding block is connected to a side of the first clamping portion away from the first limiting portion. The third limiting member also includes a second sliding block, and the second sliding block is connected to a side of the third clamping portion away from the third limiting portion. The first sliding block and the second sliding block are slidably connected in the accommodating cavity. Thus, the first bracket body can guide the first sliding block and the second sliding block, so that the first limiting member and the third limiting member can slide along the length direction of the cylindrical accommodating cavity, thereby ensuring the accuracy of the first limiting member and the third limiting member being clamped with the movable bracket respectively.

[0019] In a second aspect of the embodiment of the present application, a fixed bracket is provided, comprising a first bracket body and a first limiting member, wherein the first limiting member is connected to the first bracket body. The first limiting member comprises a first clamping portion and two first limiting portions, wherein the two first limiting portions are arranged at intervals and connected to the first clamping portion. The first clamping portion and the two first limiting portions enclose a first groove for clamping. Thus, the fixed bracket has the same technical effect as the fixed bracket in the first aspect above, which will not be described in detail here.

[0020] In a third aspect of the embodiment of the present application, a movable bracket is provided, comprising a second bracket body and a second limiting member, wherein the second limiting member is connected to the second bracket body. The second limiting member comprises a second clamping portion and two second limiting portions, wherein the two second limiting portions are arranged at intervals and connected to the second clamping portion. The second clamping portion and the two second limiting portions enclose a second groove for clamping. Thus, the movable bracket has the same technical effect as the movable bracket in the first aspect above, which will not be described in detail here.

[0021] In a fourth aspect of the embodiment of the present application, a vehicle-mounted device is provided, comprising a device body and a movable bracket, wherein the movable bracket is connected to the device body. Thus, by adding the movable bracket to the vehicle-mounted device, the difficulty of disassembling and assembling the vehicle-mounted device can be reduced. The movable bracket has the same technical effect as the movable bracket in the first aspect above, and will not be described in detail here.

[0022] In some embodiments, the vehicle-mounted device includes a plurality of movable brackets, and the movable brackets have a clamping direction. The plurality of movable brackets are connected to the same surface of the device body, and the clamping directions of the plurality of movable brackets are different. Thus, the vehicle-mounted device can be connected to the vehicle through the plurality of movable brackets, and the plurality of movable brackets with different clamping directions enable the movable brackets on the same surface of the vehicle-mounted device to withstand restraining forces in different directions, thereby making the installation of the vehicle-mounted device more secure and reliable.

[0023] According to a fifth aspect of an embodiment of the present application, a vehicle is provided, comprising a vehicle body, a vehicle-mounted device and a connecting device in the above-mentioned embodiment, wherein the vehicle-mounted device is installed in the vehicle body. A fixed bracket is connected to the vehicle body, and a movable bracket is connected to the vehicle-mounted device. The vehicle-mounted device is connected to the vehicle body via a connecting device. Thus, the connecting device provided in an embodiment of the present application is applied to the vehicle, so that the vehicle-mounted device can be connected to the vehicle body by plugging and unplugging the fixed bracket and the movable bracket. Compared with the prior art, there is no need to remove and assemble the screws one by one, which reduces the difficulty of disassembling and assembling the vehicle-mounted device, and the operation is simple and convenient.

[0024] In some embodiments, the vehicle-mounted device is a seat, and the vehicle body includes a bottom plate. The connecting device includes a first connecting device and a second connecting device having a clamping direction, the first connecting device and the second connecting device are arranged side by side, and the first connecting device and the second connecting device are connected between the seat and the bottom plate. The clamping direction of the first connecting device is the same as or perpendicular to the driving direction of the vehicle body; the clamping direction of the second connecting device is the same as or perpendicular to the driving direction of the vehicle body. Therefore, the connecting device can be applied to the seat, so that the seat can be easily disassembled and assembled on the bottom plate. At the same time, according to the different setting positions of the seat, the clamping direction of the first connecting device and the second connecting device can be the same as the driving direction of the vehicle body or perpendicular to the driving direction of the vehicle body.

[0025] In some embodiments, the vehicle-mounted equipment is a cabinet, and the vehicle body includes a bottom plate and a vehicle wall. The connecting device includes a third connecting device and a fourth connecting device with a clamping direction; the third connecting device is connected between the cabinet and the bottom plate, and the fourth connecting device is connected between the cabinet and the vehicle wall. The clamping direction of the third connecting device is the same as or perpendicular to the driving direction of the vehicle body; the clamping direction of the fourth connecting device is parallel to or perpendicular to the bottom plate. Therefore, the connecting device can also be applied to the cabinet, so that the cabinet can be easily disassembled and assembled on the bottom plate and the vehicle wall. At the same time, according to the different setting positions of the cabinet, the clamping direction of the third connecting device can be the same as the driving direction of the vehicle body or perpendicular to the driving direction of the vehicle body. The clamping direction of the fourth connecting device can be parallel to or perpendicular to the bottom plate.

[0026] In some embodiments, the connection device includes a plurality of third connection devices and a plurality of fourth connection devices, and the clamping directions of the plurality of third connection devices are different, and the clamping directions of the plurality of fourth connection devices are different. Thus, the cabinet can be connected to the bottom plate and the wall of the vehicle body through the plurality of third connection devices and the fourth connection devices with different clamping directions, so that the cabinet can withstand the restraining forces from different directions on the bottom plate and the wall of the vehicle, so that the cabinet can be stably installed in the vehicle body.

[0027] In some embodiments, the fixing bracket further includes an electrical interface and a conductive wire. The electrical interface is provided in the first bracket body, the conductive wire is electrically connected between the electrical interface and the vehicle-mounted device, and at least a portion of the conductive wire is provided in the first bracket body. Thus, the conductive wire used to connect the vehicle-mounted device can be stored in the first bracket body, avoiding damage to the conductive wire due to exposure outside the first bracket body.

DETAILED DESCRIPTION

[0057] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings.

[0058] In the following, the terms "first", "second", etc. are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0059] In addition, in the present application, directional terms such as "upper" and "lower" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they can change accordingly according to the changes in the orientation of the components in the drawings.

[0060] Currently, in the automotive field, such as Figure 1 As shown, the vehicle seat 01 is usually fixed in the vehicle by screws 011. In order to ensure the stability of the vehicle seat 01, several screws 011 are usually used to fix the vehicle seat 01 at different positions. When the vehicle seat 01 needs to be replaced or repaired, due to the large number of screws 011 and the complicated positions, it is not only necessary to disassemble and assemble the screws 011 one by one, but also necessary to follow a certain disassembly and assembly sequence to ensure that each screw 011 is evenly stressed. As a result, when disassembling and assembling the vehicle seat 01, there are problems such as difficulty in disassembly and assembly and laborious operation.

[0061] In addition, if Figure 2 As shown, for row seats, since the row seats can carry more passengers and are subjected to greater forces, the stability requirements for the vehicle seats 01 are also higher. Therefore, the row seats require more screws 011 to be fixed, and the positions of the screws 011 are more complicated, requiring professional training to disassemble and assemble them.

[0062] In order to solve the above problems, the present application embodiment provides a vehicle 02. Figure 3 As shown, the vehicle 02 may include a vehicle body 021 and a vehicle-mounted device 022, and the vehicle-mounted device 022 may be installed in the vehicle body 021. In some embodiments, Figure 3 As shown, the vehicle 02 may be a sedan, and the vehicle-mounted device 022 may be a seat 022a installed in the vehicle body 021. In other embodiments, such as Figure 4 As shown, the vehicle 02 may also be a motorhome, and the on-board equipment 022 may be a cabinet 022b and a bed 022c installed in the vehicle body 021 .

[0063] In addition, the vehicle 02 may also be an off-road vehicle, a truck, or a bus, and the vehicle 02 may be a fuel-powered vehicle, a hybrid vehicle, or a pure electric vehicle. The embodiment of the present application does not impose any special restrictions on the vehicle model and power mode of the vehicle 02. As the user's demand for the vehicle-mounted device 022 increases, the vehicle-mounted device 022 may also be a sofa, a television, a kitchen device, or other equipment installed in the vehicle body 021. The embodiment of the present application does not impose any special restrictions on the specific type of the vehicle-mounted device 022.

[0064] Among them, Figure 3 and Figure 4 As shown, the vehicle 02 may have a length direction, a width direction, and a height direction. In the following embodiments, for the convenience of explanation, the X direction is used as the length direction of the vehicle 02, the Y direction is used as the width direction of the vehicle 02, and the Z direction is used as the height direction of the vehicle 02. Taking a car as an example, the driving direction of the car can be used as the length direction of the car, the height direction of the car from the ground can be used as the height direction of the car, and the Y direction can be perpendicular to the X direction and the Z direction.

[0065] In order to reduce the difficulty of disassembling and assembling the vehicle-mounted device 022, Figure 3 and Figure 5 As shown, the embodiment of the present application further provides a connection device 03, which can be installed in the vehicle body 021 and can be used to connect the vehicle-mounted device 022 to simplify the disassembly and assembly operation of the vehicle-mounted device 022. The following embodiment will describe the specific structure of the connection device 03 in detail.

[0066] In some embodiments, Figure 6 As shown, the connecting device 03 may include a fixed bracket 100 and a movable bracket 200. The fixed bracket 100 may be connected to the vehicle body 021 ( Figure 3 The movable bracket 200 can be connected with the vehicle-mounted device 022 ( Figure 3 As shown in the figure, the vehicle-mounted device 022 is connected to the vehicle body 021. As a result, the vehicle-mounted device 022 can be installed in the vehicle body 021 through the connecting device 03. Among them, the fixed bracket 100 can be integrally formed with the vehicle body 021, or it can be designed as a structural member independent of the vehicle body 021. Similarly, the movable bracket 200 can be integrally formed with the vehicle-mounted device 022, or it can be designed as a structural member independent of the vehicle-mounted device 022. The embodiment of the present application does not impose any special restrictions on the arrangement of the fixed bracket 100 and the movable bracket 200.

[0067] For example, Figure 7As shown, the fixed bracket 100 may include a first bracket body 110, a telescopic device 120 and a first stopper 130. The telescopic device 120 may be connected to the first stopper 130 and installed in the fixed bracket 100. The movable bracket 200 may include a second bracket body 210 and a second stopper 220, and the second stopper 220 may be connected to the second bracket body 210. The following embodiments will describe the specific structures of the fixed bracket 100 and the movable bracket 200 in detail.

[0068] Specifically, for the first bracket body 110, if Figure 8 As shown, the overall shape of the first bracket body 110 can be set to a rectangular parallelepiped shape and have a length along the X direction. The first bracket body 110 may include a top plate 110a and a back plate 110c arranged along the XY plane, a side plate 110b arranged along the XZ plane, and an end plate 110d arranged along the YZ plane. The top plate 110a, the side plate 110b, the back plate 110c, and the end plate 110d may enclose a cylindrical accommodating cavity 111, and the cylindrical accommodating cavity 111 may have a length along the X direction for accommodating the telescopic device 120 ( Figure 7 as shown) and the first stopper 130 ( Figure 7 A first connection hole 112 may be provided on the top plate 110a for inserting the second stopper 220 ( Figure 7 Of course, the first bracket body 110 may also be configured as a cylindrical barrel structure, and the embodiment of the present application does not impose any special restrictions on the specific structure of the first bracket body 110.

[0069] For the telescopic device 120, if Fig. 9 As shown, the telescopic device 120 may include a driving member 121, a sleeve 122 and a screw 123a. The driving member 121 may be a servo motor, a stepper motor, a brushed motor, a brushless motor or other motor types. The embodiment of the present application does not impose any special restrictions on the specific type of the driving member 121. The driving member 121 may include a connected driving member body 1211 and an output shaft 1212, and the output shaft 1212 may rotate relative to the driving member body 1211. The sleeve 122 may be connected and fixed to the output shaft 1212, and the connection method may be welding, screw connection, interference connection or connection through a coupling, so that the output shaft 1212 can drive the sleeve 122 to rotate in the forward and reverse directions. The embodiment of the present application does not impose any special restrictions on the connection method between the sleeve 122 and the output shaft 1212. The screw 123a may be threadedly connected in the sleeve 122, and the first limit member 130 ( Figure 7 The first stopper 130 and the screw rod 123a are connected to each other by welding, screw connection or interference connection. The embodiment of the present application does not impose any special restrictions on the connection method between the first stopper 130 and the screw rod 123a.

[0070] For example, Figure 7 and Fig. 9 As shown, the telescopic device 120 can be connected to the accommodating cavity 111 ( Figure 8 When the output shaft 1212 drives the sleeve 122 to rotate forward and reversely, the screw rod 123a can be telescopically moved relative to the sleeve 122 along the X direction, so that the first limiter 130 can slide along the X direction in the accommodation cavity 111. Of course, the above embodiment can also connect and fix the screw rod 123a with the output shaft 1212, use a nut to thread the screw rod 123a, and then connect and fix the first limiter 130 with the nut, which can also make the first limiter 130 slide along the X direction in the accommodation cavity 111. The embodiment of the present application does not impose any special restrictions on the specific structure of driving the first limiter 130 to move.

[0071] On this basis, if Fig.10 As shown, the thread of the thread on the sleeve 122 may include a first straight surface 1221 and a first inclined surface 1222, and the first straight surface 1221 faces the first stopper 130 side, and the first inclined surface 1222 faces away from the first stopper 130 side. The thread of the thread on the screw rod 123a may include a second straight surface 1231 and a second inclined surface 1232. In addition, the second straight surface 1231 faces away from the first stopper 130 side, and the second inclined surface 1232 faces the first stopper 130 side. In this way, a unidirectional transmission thread can be formed between the sleeve 122 and the screw rod 123a. When the sleeve 122 is threadedly connected with the screw rod 123a, the first straight surface 1221 can abut against the second straight surface 1231, and the first inclined surface 1222 can fit with the second inclined surface 1232. Thus, the screw rod 123a can be stopped in the direction away from the first limit member 130 to prevent the screw rod 123a from retracting relative to the sleeve 122, thereby realizing the one-way transmission function of the screw rod 123a and the self-locking function of the screw rod 123a.

[0072] In addition, the telescopic device 120 can also use a structure in which a worm gear and a worm gear cooperate. For example, the turbine can be connected and fixed to the output shaft 1212 of the driving member 121, the turbine can be meshed and connected to the worm, and the worm can be connected to the first limit member 130. When the output shaft 1212 drives the turbine to rotate, the turbine can drive the worm to move telescopically along the X direction, and can also make the first limit member 130 slide in the accommodating chamber 111 along the X direction. Moreover, the cooperation between the turbine and the worm gear also has a self-locking function. In addition, the telescopic device 120 can also use a cylinder, a hydraulic cylinder, an electric push cylinder and other driving devices that can realize the telescopic function. These driving devices can also have a self-locking function, such as a hydraulic tappet. The embodiment of the present application does not impose any special restrictions on the specific structure of the telescopic device 120.

[0073] For the first limiting member 130, if Fig.11 As shown, the first stopper 130 may include a first clamping portion 131, a first stopper 132 and a first sliding block 134. The first clamping portion 131 may be a plate-like structure arranged in the XY plane, the first stopper 132 may be a columnar structure along the X direction, and the two first stoppers 132 may be arranged at intervals along the Y direction. The shape of the first sliding block 134 in the YZ plane may be the same as that of the above-mentioned accommodating cavity 111 ( Figure 8 The first sliding block 134 can slide in the accommodating cavity 111 along the X direction and avoid rotating in the accommodating cavity 111. Along the X direction, the first clamping portion 131 can be connected to one side of the first sliding block 134, and the other side of the first sliding block 134 can be connected to the screw rod 123a ( Fig.10 In order to prevent the first sliding block 134 from rotating in the accommodating chamber 111, bearings, joints and other components may be provided between the first sliding block 134 and the screw rod 123a. The two first limiting portions 132 may be connected to the side of the first clamping portion 131 away from the first sliding block 134, and may be arranged side by side at both ends of the first clamping portion 131 along the Y direction, so that the first clamping portion 131 and the two first limiting portions 132 enclose a first groove 133.

[0074] Among them, Fig.11 As shown, the first groove 133 may include a first groove bottom 1331 and a first groove wall 1332, the first groove bottom 1331 is arranged in the YZ plane of the first clamping portion 131, the first groove wall 1332 is arranged in the XZ plane of the first limiting portion 132, and the first groove walls 1332 on the two first limiting portions 132 are arranged opposite to each other. In addition, the first clamping portion 131 and the first sliding block 134 may be connected to form a T-shaped structure, and a first abutting surface 1311 is further arranged in the XY plane of the first clamping portion 131. The first limiting member 130 may be a structural member integrally formed by the first clamping portion 131, the first limiting portion 132 and the first sliding block 134, or may be a structural member formed by welding, screwing or riveting the first clamping portion 131, the first limiting portion 132 and the first sliding block 134.

[0075] In some embodiments, please combine Figure 8 and Fig.11, the first sliding block 134 can be loosely matched with the top plate 110a, the side plate 110b and the back plate 110c in the first bracket body 110, so that the first bracket body 110 can guide the sliding of the first sliding block 134. At the same time, the first limiting portion 132 can also be loosely matched with the side plate 110b in the first bracket body 110, so that the side plate 110b can limit and block the first limiting portion 132 in the Y direction. Since the first clamping portion 131 and the first sliding block 134 are connected to form a T-shaped structure, the first clamping portion 131 can be spaced apart from the top plate 110a and the back plate 110c in the first bracket body 110.

[0076] The above embodiment is a detailed introduction to the specific structure of the first bracket body 110, the telescopic device 120 and the first limiter 130 in the fixed bracket 100. The following embodiment will give a detailed introduction to the specific structure of the movable bracket 200. Fig.12 As shown, the movable bracket 200 may further include a buffer pad 230, which may be connected to the second bracket body 210 and disposed on the outer periphery of the second stopper 220. Figure 7 and Figure 8 As shown, the second bracket body 210 can be connected to the first bracket body 110, and the second stopper 220 can be inserted into the first connection hole 112. The buffer pad 230 can play a role of vibration reduction and buffering between the first bracket body 110 and the second bracket body 210 to avoid damage to the fixed bracket 100 when installing the movable bracket 200.

[0077] Specifically, for the second bracket body 210, if Fig.12 As shown, the second bracket body 210 can be configured as a plate structure in the XY plane, so that the second bracket body 210 can be attached to the first bracket body 110 ( Figure 8 The top plate 110a (shown) Figure 8 Of course, when the first bracket body 110 is configured as a cylindrical barrel structure, the second bracket body 210 can also be configured as an arc plate structure, and the curvature of the second bracket body 210 is the same as the curvature of the cylindrical barrel of the first bracket body 110. The embodiment of the present application does not impose any special restrictions on the specific structure of the second bracket body 210.

[0078] For the second limiting member 220, if Fig.13As shown, the second position-limiting member 220 may include a second clamping portion 221 and a second position-limiting portion 222. The second clamping portion 221 may be a block-shaped structure, and the second position-limiting portion 222 may be a plate-shaped structure arranged in the XY plane. The two second position-limiting portions 222 may be arranged at intervals along the Z direction and connected to the two ends of the second clamping portion 221. In this way, the second clamping portion 221 and the two second position-limiting portions 222 surround a second groove 223.

[0079] Among them, Fig.13 As shown, the second groove 223 may include a second groove bottom 2231 and a second groove wall 2232, the second groove bottom 2231 is arranged in the YZ plane of the second clamping portion 221, the second groove wall 2232 is arranged in the XY plane of the second limiting portion 222, and the second groove walls 2232 on the two second limiting portions 222 are arranged opposite to each other. In addition, a second abutting surface 2211 is also arranged in the XZ plane of the second clamping portion 221. The second limiting member 220 may be a structural member integrally formed by the second clamping portion 221 and the second limiting portion 222, or may be a structural member formed by welding, screwing or riveting the second clamping portion 221 and the second limiting portion 222.

[0080] The above embodiment is a detailed introduction to the specific structure of the second bracket body 210 and the second stopper 220 in the movable bracket 200. The following embodiment will give a detailed introduction to the connection principle between the fixed bracket 100 and the movable bracket 200. Fig.14 As shown, the first stopper 130 ( Fig.11 As shown in FIG. 1 , under the driving force of the screw rod 123a, the second stopper 220 ( Fig.13 As shown) move. Combine Fig.15 As shown, when the first stopper 130 is connected to the second stopper 220, under the thrust of the screw rod 123a, the first groove bottom 1331 abuts against the second groove bottom 2231, so that the first stopper 130 and the second stopper 220 can be locked with each other in the X direction. Fig.11 The first stopper 130 and the second stopper 220 are located in the second groove 223, and the first abutting surface 1311 can abut against the second groove wall 2232, so that the first stopper 130 and the second stopper 220 can be locked with each other in the Z direction. Fig.13 As shown in the figure, the first limiting member 130 and the second limiting member 220 are located in the first groove 133, and the second abutting surface 2211 can abut against the first groove wall 1332, so that the first limiting member 130 and the second limiting member 220 can be locked with each other in the Y direction.

[0081] From this we can see that Figure 7 and Figure 8As shown, the telescopic device 120 and the first stopper 130 can be installed in the accommodating cavity 111 of the first bracket body 110, and the second stopper 220 on the movable bracket 200 can be inserted into the accommodating cavity 111 through the first connecting hole 112 on the top plate 110a. At this time, the first stopper 130 can be moved toward or away from the second stopper 220 along the X direction by controlling the telescopic device 120, so that the fixed bracket 100 can lock or unlock the movable bracket 200 in the three directions of XYZ. When the fixed bracket 100 is connected to the movable bracket 200, the first stopper 130 and the second stopper 220 can be mutually engaged to form a "handshake" structure. The first stopper 130 and the second stopper 220 can be connected by mutually engaging, which has a simple structure and is easy to operate.

[0082] When installing the vehicle-mounted device 022, it is only necessary to connect the movable bracket 200 on the vehicle-mounted device 022 with the fixed bracket 100 on the vehicle body 021 and control the extension of the telescopic device 120 to complete the installation of the vehicle-mounted device 022. When disassembling the vehicle-mounted device 022, it is only necessary to control the contraction of the telescopic device 120 and remove the movable bracket 200 on the vehicle-mounted device 022 from the fixed bracket 100 on the vehicle body 021 to complete the disassembly of the vehicle-mounted device 022. In this way, compared with the prior art, the connection device 03 provided in the embodiment of the present application does not need to find the screws 011 one by one ( Figure 1 The screws 011 can be removed one by one without following the order of removing and installing the screws 011, which greatly reduces the difficulty of removing and installing the vehicle-mounted device 022.

[0083] At the same time, if Fig.11 and Fig.13 As shown, after the first stopper 130 and the second stopper 220 are connected, the first stopper 130 can limit the movement of the second clamping portion 221 between the two first stopper portions 132 through the two first stopper portions 132, and the second stopper 220 can also limit the movement of the first clamping portion 131 between the two second stopper portions 222 through the two second stopper portions 222. In this way, not only the function of connecting the fixed bracket 100 with the movable bracket 200 is achieved, but also the fixed bracket 100 and the movable bracket 200 can be locked with each other in the three directions of XYZ, thereby ensuring the stability of the connection between the fixed bracket 100 and the movable bracket 200, thereby avoiding the vehicle-mounted equipment 022 ( Figure 3 (as shown) the problem of unlocking under vehicle operating conditions.

[0084] The above embodiment is described by taking the first clamping portion 131 and the second limiting portion 222 as a plate structure arranged in the XY plane as an example. In addition, the first clamping portion 131 and the second limiting portion 222 can also be set as a plate structure in the XZ plane. In this case, the two first limiting portions 132 can be arranged side by side along the Z direction and connected to the first clamping portion 131. In this way, the fixed bracket 100 can also lock the movable bracket 200 in the three directions of XYZ by connecting the first limiting member 130 with the second limiting member 220. Alternatively, the fixed bracket 100 and the movable bracket 200 are unlocked by separating the first limiting member 130 from the second limiting member 220.

[0085] In order to improve the first limit member 130 ( Fig.11 ) and the second stopper 220 ( Fig.13 The stability of the connection between Fig.15 As shown, the length S1 of the second position-limiting portion 222 along the X direction can also be set to be smaller than the length S2 of the first clamping portion 131 along the X direction. That is, when the first position-limiting member 130 is connected to the second position-limiting member 220, there can be a gap 135 between the second position-limiting portion 222 and the first sliding block 134, so that the first groove bottom 1331 can preferentially abut against the second groove bottom 2231. In this way, there is no gap in the X direction between the first position-limiting member 130 and the second position-limiting member 220, thereby avoiding relative shaking between the first position-limiting member 130 and the second position-limiting member 220 and ensuring the stability of the connection between the first position-limiting member 130 and the second position-limiting member 220. At the same time, after long-term use, when the first groove bottom 1331 and the second groove bottom 2231 are worn, the first limit member 130 and the second limit member 220 can also limit the movement of the first limit member 130 and the second limit member 220 along the X direction through the abutment between the second limit portion 222 and the first sliding block 134.

[0086] In addition, if Fig.11 As shown, the thickness of the first clamping portion 131 along the Z direction may be slightly greater than the second groove 223 ( Fig.13 The width along the Z direction is as shown in FIG. 1 , so that the first abutting surface 1311 can be interference-fitted with the second groove wall 2232. Fig.13 As shown, the thickness of the second clamping portion 221 along the Y direction may be slightly greater than the first groove 133 ( Fig.11 The width of the first stopper 130 along the Y direction is as shown in the figure, so that the second abutting surface 2211 can be interference-fitted with the first groove wall 1332. Therefore, there is no gap between the first stopper 130 and the second stopper 220 in the Y direction and the Z direction, thereby avoiding the relative shaking between the first stopper 130 and the second stopper 220 and ensuring the stability of the connection between the first stopper 130 and the second stopper 220.

[0087] In some embodiments, Fig.16 and Fig.17 As shown, a first guide angle 137 may be provided on the side of the first clamping portion 131 facing the first limiting portion 132. A second guide angle 136 may be provided on the side of the first limiting portion 132 away from the first clamping portion 131, and the second guide angles 136 on the two first limiting portions 132 are arranged oppositely. A third guide angle 225 may be provided on the side of the second clamping portion 221 facing the second limiting portion 222. A fourth guide angle 224 may be provided on the side of the second limiting portion 222 away from the second clamping portion 221, and the fourth guide angles 224 on the two second limiting portions 222 are arranged oppositely. The second guide angle 136 may include a second vertical guide angle 136a and a second horizontal guide angle 136b. The fourth guide angle 224 may include a fourth vertical guide angle 224a and a fourth horizontal guide angle 224b.

[0088] In the XZ plane, if Fig.16 As shown, in the first stopper 130 ( Fig.11 ) and the second stopper 220 ( Fig.13 During the connection process (shown in FIG. 1 ), the first position-limiting member 130 and the second position-limiting member 220 can be connected to each other by the cooperation of the second vertical guide angle 136a and the fourth vertical guide angle 224a, thereby avoiding collision damage between the first position-limiting member 132 and the second position-limiting member 222. Furthermore, the first guide angle 137 and the fourth vertical guide angle 224a can be connected to avoid collision damage between the first clamping portion 131 and the second position-limiting member 222, and the first clamping portion 131 and the second position-limiting member 222 can be guided, so that the first position-limiting member 130 and the second position-limiting member 220 can be smoothly plugged in the XZ plane.

[0089] In the XY plane, Fig.17 As shown, in the first stopper 130 ( Fig.11 ) and the second stopper 220 ( Fig.13 During the connection process (shown in FIG. 1 ), the first position-limiting member 130 and the second position-limiting member 220 can be connected to each other by the cooperation of the second horizontal guide angle 136b and the fourth horizontal guide angle 224b, thereby avoiding collision damage between the first position-limiting member 132 and the second position-limiting member 222. The second horizontal guide angle 136b and the third guide angle 225 can also avoid collision damage between the first position-limiting member 132 and the second clamping member 221, and guide the first position-limiting member 132 and the second clamping member 221, so that the first position-limiting member 130 and the second position-limiting member 220 can be smoothly plugged in the XY plane.

[0090] Therefore, by setting the second guide angle 136 on the first limit portion 132, setting the fourth guide angle 224 on the second limit portion 222, setting the first guide angle 137 on the first clamping portion 131, and setting the third guide angle 225 on the second clamping portion 221, damage to the first limit member 130 and the second limit member 220 can be effectively avoided, thereby improving the service life of the connecting device 03. Among them, the second guide angle 136, the fourth guide angle 224, the first guide angle 137 and the third guide angle 225 can be rounded angles or inclined angles, and the embodiment of the present application does not impose any special restrictions on the types of the second guide angle 136, the fourth guide angle 224, the first guide angle 137 and the third guide angle 225.

[0091] Of course, there is no need for interference fit between the first limiting member 130 and the second limiting member 220. Fig.16 and Fig.17 As shown, the connecting device 03 ( Figure 7 The first elastic pad layer 226 and the second elastic pad layer 138 may be provided between the first clamping portion 131 and the second limiting portion 222, and the second elastic pad layer 138 may be provided between the second clamping portion 221 and the first limiting portion 132. When the first limiting member 130 is connected to the second limiting member 220, the first elastic pad layer 226 and the second elastic pad layer 138 may also prevent the first limiting member 130 from shaking relative to the second limiting member 220, thereby ensuring the stability of the connection between the first limiting member 130 and the second limiting member 220.

[0092] The above embodiment is described by taking the first bracket body 110 as an example in which a set of first limiting members 130 and second limiting members 220 are arranged in the first bracket body 110. In more embodiments, for example, Fig.18 As shown, a set of third stopper 140 and fourth stopper 240 may also be provided in the connection device 03. Specifically, a second connection hole 113 may also be provided on the first bracket body 110, and the first connection hole 112 and the second connection hole 113 may be provided side by side along the X direction. Of course, the first connection hole 112 and the second connection hole 113 may also be directly connected. The embodiment of the present application does not impose any special restrictions on the opening method of the first bracket body 110.

[0093] The difference from the above implementation is that if Fig.18 As shown, the telescopic device 120 ( Fig. 9 The embodiment of the present invention may include a driving member 121 and a bidirectional screw rod 123b. That is, the bidirectional screw rod 123b may be used to replace the screw rod 123a ( Fig. 9 As shown). The driving member 121 can be connected to the bidirectional screw rod 123b to drive the bidirectional screw rod 123b to rotate. Fig.19As shown, the bidirectional screw rod 123b may include a first screw thread portion 124 and a second screw thread portion 125 with opposite threads. The first screw thread portion 124 and the second screw thread portion 125 may be selected from the unidirectional transmission threads in the above embodiment, which will not be described in detail here.

[0094] On this basis, if Fig. 20 As shown, the fixing bracket 100 ( Figure 7 The first sliding block 134 can be threadedly connected to the first screw thread portion 124 on the bidirectional screw rod 123b, and the second sliding block 144 can be threadedly connected to the second screw thread portion 125 on the bidirectional screw rod 123b. Corresponding threaded holes can be respectively provided on the first sliding block 134 and the second sliding block 144, so that the first sliding block 134 is threadedly connected to the first screw thread portion 124, and the second sliding block 144 is threadedly connected to the second screw thread portion 125. The threaded connection can also be performed by respectively providing nuts on the first sliding block 134 and the second sliding block 144, and the specific structure of the threaded connection is not particularly limited in the embodiment of the present application. The third clamping portion 141 can be disposed on a side of the second sliding block 144 away from the bidirectional screw rod 123b, and the two third limiting portions 142 can be disposed on a side of the third clamping portion 141 away from the second sliding block 144. The third clamping portion 141 and the two third limiting portions 142 can enclose a third groove 143. In this way, the first limiting member 130 and the third limiting member 140 can slide in opposite directions in the X direction.

[0095] At the same time, if Fig.21 As shown, the movable bracket 200 ( Figure 7 ) may also include a fourth stopper 240 ( Fig.18 As shown in FIG. 1 , the fourth stopper 240 may include a fourth clamping portion 241 and a fourth stopper 242. The fourth clamping portion 241 and the two fourth stopper portions 242 may form a fourth groove 243. In this way, the telescopic device 120, the first stopper 130 and the third stopper 140 may be disposed in the accommodating cavity 111 of the first bracket body 110 ( Figure 8 As shown), after the second bracket body 210 is connected to the first bracket body 110, the second limiting member 220 can be inserted into the accommodating cavity 111 through the first connecting hole 112, and the fourth limiting member 240 can be inserted into the accommodating cavity 111 through the second connecting hole 113.

[0096] Similarly, only by controlling the extension and retraction of the retractable device 120, the first limiter 130 can be moved toward the second limiter 220 along the X direction, and the third limiter 140 can be moved toward the fourth limiter 240 along the opposite direction of the X direction. When the first limiter 130 is located in the second groove 223 and the second limiter 220 is located in the first groove 133, the first limiter 130 and the second limiter 220 are locked in the three directions of X, Y, and Z. When the third limiter 140 is located in the fourth groove 243 and the fourth limiter 240 is located in the third groove 143, the third limiter 140 and the fourth limiter 240 are locked in the three directions of X, Y, and Z.

[0097] On this basis, in order to better control the extension and retraction of the retractable device 120, as Fig. 22 As shown, the fixing bracket 100 of the connecting device 03 may also include a switch button 114, an electrical interface 115 and a conductive wire 116. The switch button 114 and the electrical interface 115 may be arranged on the first bracket body 110 ( Fig.18 For example, the switch button 114 can be connected to the end plate 110d ( Figure 8 The electrical interface 115 can be connected to the top plate 110a ( Figure 8 The present embodiment does not impose any special restrictions on the specific positions of the switch button 114 and the electrical interface 115. In addition, the switch button 114 can be connected to the telescopic device 120 ( Fig. 9 The driving member 121 (shown) Fig. 9 The electrical interface 115 can be electrically connected to the switch button 114 and the driving member 121 respectively. The conductive wire 116 can be electrically connected between the electrical interface 115 and the vehicle-mounted device 022 ( Figure 3 As shown), and at least a portion of the conductive wire 116 can be disposed within the first bracket body 110.

[0098] In this way, the user can control the extension and retraction of the telescopic device 120 by clicking the switch button 114, which is simple and convenient to operate. After the telescopic device 120 drives the first limiter 130 and the second limiter 220 to lock each other, the driving member 121 in the telescopic device 120 can be in a power-off state, which can not only reduce the energy consumption of the driving member 121, but also cooperate with the self-locking function of the telescopic device 120 to keep the first limiter 130 and the second limiter 220 in a mutually locked state. When it is necessary to disassemble the vehicle-mounted device 022, the driving member 121 is powered on again, and the telescopic device 120 is controlled to retract by clicking the switch button 114. In addition, when the driving member 121 is in a power-off state (for example, when the vehicle 02 is turned off), the setting of the electrical interface 115 allows the driving member 121 to be powered by an external power source (for example, a power bank), so that there is no need to repeatedly start and stop the vehicle 02 when disassembling the vehicle-mounted device 022, thereby improving the life of the vehicle 02. In addition, the conductive wire 116 used to connect the vehicle-mounted device 022 can be stored in the first bracket body 110 to avoid damage to the conductive wire 116 .

[0099] The above embodiment is for the connection device 03 ( Fig. 22 In order to better illustrate the connection device 03 in the vehicle-mounted device 022 ( Figure 3 The following will introduce the application scenarios of the connection device 03 in detail in combination with different vehicle-mounted devices 022. Fig.23 As shown, the vehicle-mounted device 022 may include a device body 0220 and a movable bracket 200 ( Fig. 22 As shown), the device body 0220 is provided with a seat 022a ( Figure 3 As shown in the figure, the connecting device 03 may include a first connecting device 03a and a second connecting device 03b.

[0100] When installing the seat 022a, the first movable bracket 200a can be connected to the first fixed bracket 100a, and the second movable bracket 200b can be connected to the second fixed bracket 100b. When disassembling the seat 022a, the first movable bracket 200a can be separated from the first fixed bracket 100a, and the second movable bracket 200b can be separated from the second fixed bracket 100b. Of course, if the seating direction of the seat 022a is set along the Y direction (for example, some seats 022a on a bus), the two sets of connecting devices 03 can still be set along the X direction. At this time, the length direction of the connecting device 03 is perpendicular to the seating direction of the seat 022a.

[0101] In addition, in some embodiments, Fig.23 As shown, some seats 022a ( Figure 3 Specifically, vehicle 02 ( Figure 3 The connecting device 03 (shown) may also include a slidably connected track 023 and a slide groove 024, the track 023 may be connected and fixed to the bottom plate 021a, and the slide groove 024 may be slidably connected to the track 023.

The third movable bracket 200c corresponds to the position of the third fixed bracket 100c, and the fourth movable bracket 200d corresponds to the position of the fourth fixed bracket 100d.

[0102] When installing the cabinet 022b, the third movable bracket 200c can be connected to the third fixed bracket 100c, and the fourth movable bracket 200d can be connected to the fourth fixed bracket 100d. When disassembling the cabinet 022b, the third movable bracket 200c can be separated from the third fixed bracket 100c, and the fourth movable bracket 200d can be separated from the fourth fixed bracket 100d. Of course, according to the different directions in which the cabinet 022b is set in the vehicle body 021, the length direction of the third movable bracket 200c and the third fixed bracket 100c can be set along the X direction or the Y direction. The length direction of the fourth movable bracket 200d and the fourth fixed bracket 100d can be set along the Y direction or the Z direction.

The clamping direction of a portion of the third connecting devices 03c in the plurality of third connecting devices 03c may be provided along the X direction, and the clamping direction of another portion of the third connecting devices 03c may be provided along the Y direction. In this way, the cabinet 022b and the bottom plate 021a may withstand the restraining force from the X direction and the Y direction, so that the cabinet 022b may be firmly fixed on the bottom plate 021a. Similarly, the clamping direction of a portion of the fourth fixed brackets 100d in the plurality of fourth fixed brackets 100d may be provided along the Y direction, and the clamping direction of another portion of the fourth fixed brackets 100d may be provided along the Z direction. In this way, the cabinet 022b and the vehicle wall 021b can withstand the restraining force from the Y direction and the Z direction, so that the cabinet 022b can be firmly fixed on the vehicle wall 021b. Figure 3As shown), the cabinet 022b is prevented from being damaged due to vibration under vehicle-mounted conditions.

[0104] In addition, the device body 0220 can also be a bed 022c. For example, Fig.26 As shown, according to the vehicle-mounted device 022 ( Figure 3 The type of vehicle body 021 ( Figure 3 More number of connection devices 03 can be set in the vehicle wall 021b (as shown). When the vehicle-mounted device 022 is a bed 022c, one group of connection devices 03 can be set on the vehicle wall 021b along the Y direction, and two groups of connection devices 03 can be set on the bottom plate 021a along the X direction. Of course, depending on the type of the vehicle-mounted device 022, the length direction of the connection device 03 can also be set along different directions. The embodiment of the present application does not impose any special restrictions on the number and direction of the connection device 03.

[0105] For example, Fig. 27 As shown, a plurality of third connecting devices 03c may be provided between the bed 022c and the bottom plate 021a, and the clamping direction of a portion of the third connecting devices 03c may be provided along the X direction, and the clamping direction of another portion of the third connecting devices 03c may be provided along the Y direction. In this way, the bed 022c and the bottom plate 021a may withstand the restraining force from the X direction and the Y direction, so that the bed 022c may be firmly fixed on the bottom plate 021a.

[0106] Of course, the connection device 03 provided in the embodiment of the present application can also be applied to more vehicle-mounted devices 022, such as vehicle-mounted tables, vehicle-mounted kitchen equipment, etc. According to the different shapes, structures and stress characteristics of the vehicle-mounted devices 022, the connection device 03 can also be set between the vehicle body 021 and the vehicle-mounted devices 022 in other different directions to meet the stress requirements of the vehicle-mounted devices 022 under vehicle-mounted working conditions.
