Description

Technical Field

[0001] This application belongs to the technical field of vehicle accessory installation, specifically relating to an extension mounting bracket and a vehicle. Background Technology

[0002] With the rapid development of vehicle networking technology, more and more electronic devices need to be installed and used. For example, in order to facilitate the collection of data during vehicle testing, data acquisition terminals need to be installed inside the vehicle.

[0003] To increase the stability of electronic devices, they are typically installed inside vehicles in two ways. One method involves using a fixed bracket to mount the device, which in turn is fixed to the vehicle. While this increases stability, tools are required for installation and removal, thus affecting ease of disassembly. The other method uses adhesive bonding, but this bonding weakens over time, also impacting stability. Therefore, improving the ease of installation and removal while ensuring the stability of electronic devices has become a pressing technical challenge. Utility Model Content

[0004] This application provides an extended mounting bracket to improve the ease of mounting and dismounting electronic devices and to ensure the stability of electronic devices.

[0005] The technical solution adopted in this application is as follows: An extended mounting bracket includes a fixed frame and a magnetic base connected to the fixed frame. The magnetic base is capable of magnetically attracting ferromagnetic materials. The magnetic base has a mounting position for mounting electronic devices and a hand-receiving groove located at the bottom of the mounting position. The magnetic base is movable relative to the fixed frame to have a first position and a second position. When the magnetic base is in the second position, the hand-receiving groove avoids contact with the fixed frame.

[0006] By adopting the above technical solution, when using the extended mounting bracket in this application to fix the electronic device, the extended mounting bracket is first installed inside the vehicle, that is, the mounting bracket is fixedly installed inside the vehicle, and then the electronic device is installed in the mounting position so that the iron piece on the electronic device is magnetically engaged with the magnetic base, thereby realizing the installation of the electronic device inside the vehicle; when disassembling the electronic device, the magnetic base is first operated to make the magnetic base and the mounting bracket move relative to each other, so that the magnetic base moves from the first position to the second position, so that the hand slot and the mounting bracket are separated, and then the worker puts his hand into the hand slot and applies a force to separate the electronic device from the magnetic base, finally causing the iron piece on the electronic device to disengage from the magnetic base, thereby completing the disassembly of the electronic device.

[0007] In summary, compared to existing technologies that use fixed brackets to install electronic devices inside vehicles, the extended mounting bracket in this application eliminates the need for tools when assembling and disassembling electronic devices, thus improving the convenience of installation and disassembly. Compared to existing technologies that use adhesive methods to install electronic devices, it avoids the instability of electronic devices due to the increasing installation time, thereby ensuring the stability of the electronic devices. Furthermore, the magnetic base in this application has a second position. When the magnetic base is in the second position, the hand slot avoids the fixing bracket, allowing the operator to insert their hand into the hand slot to apply a force to separate the electronic device from the magnetic base, further facilitating the disassembly of the electronic device.

[0008] Optionally, one of the fixing frame and the magnetic base is provided with a sliding groove, and the other is provided with a slide rail adapted to the sliding groove. The slide rail is slidably connected to the sliding groove, and the width of the groove opening is smaller than the width of the groove bottom.

[0009] By adopting the above technical solution, since one of the mounting bracket and the magnetic base is provided with a sliding groove, and the other is provided with a sliding rail adapted to the sliding groove, the sliding rail is slidably connected to the sliding groove, thereby realizing the sliding connection between the magnetic base and the mounting bracket. Simultaneously, the sliding cooperation between the sliding rail and the sliding groove can guide the magnetic base, increasing the stability of the magnetic base during sliding. Furthermore, since the width of the groove opening is smaller than the width of the groove bottom, and the sliding rail is adapted to the sliding groove, the cooperation between the sliding rail and the sliding groove can also limit the magnetic base, preventing it from detaching from the mounting bracket in a direction perpendicular to its sliding direction. This further increases the connection stability between the magnetic base and the mounting bracket, thereby further enhancing the stability of the electronic device.

[0010] Optionally, the magnetic base has a positioning piece located on the side of the mounting position.

[0011] By adopting the above technical solution, since the positioning piece is located on the side of the installation position, it can be used to position the electronic device, so as to facilitate the staff to install the electronic device in place and further improve the installation efficiency of the electronic device. On the other hand, it can also be used to limit the electronic device installed in the installation position, so as to further increase the stability of the electronic device.

[0012] Optionally, the fixing frame has a fixing rod located on the side of the magnetic base, the fixing rod is provided with a locking member, the magnetic base has a locking groove, and the locking member can move relative to the fixing rod so that the locking member has a locking position extending into the locking groove and an unlocking position disengaging from the locking groove.

[0013] By adopting the above technical solution, since the locking component is located on the fixed rod and the locking groove is located on the magnetic base, and the locking component has a locking position that extends into the locking groove and an unlocking position that disengages from the locking groove, on the one hand, the magnetic base can be limited by the insertion and cooperation of the locking component and the locking groove to increase the stability of the magnetic base and prevent the magnetic base from moving relative to the fixed frame when the vehicle is driving on bumpy roads, thereby further increasing the stability of the electronic device. On the other hand, when disassembling the electronic device, the locking component can be moved to the unlocking position by operating the locking component, so that the locking component is separated from the locking groove, and the magnetic base can move relative to the fixed frame to ensure the convenience of disassembling the electronic device.

[0014] Optionally, the fixing rod is provided with a through hole and a receiving cavity communicating with the through hole. The locking member includes a locking part passing through the through hole and an elastic part located in the receiving cavity. The elastic part is used to apply an elastic force to the locking part toward the side where the magnetic base is located. When the locking member is in the locking position, part of the locking part extends into the locking groove.

[0015] By adopting the above technical solution, when driving the locking member toward the unlocking position, a pulling force away from the magnetic base is first applied to the locking part to make the locking part move relative to the fixed rod. At the same time, the locking part compresses the elastic part, causing the elastic part to undergo elastic deformation, ultimately separating the locking part from the locking groove, thus completing the driving of the locking member from the locked position to the unlocking position. In this process, only a pulling force needs to be applied to the locking part, thereby achieving the effect of facilitating the driving of the locking member to the unlocking position. When the locking member needs to move to the locked position, the operator's hand only needs to be separated from the locking part. At this time, the elastic part restores its deformation, and the locking part automatically moves toward the locked position under the action of the elastic part, thereby achieving the effect of facilitating the driving of the locking member to the locked position. At the same time, by setting the elastic part, when driving the locking member toward the unlocking position, it is necessary to overcome the elastic force of the elastic part, which increases the force required for the locking member to move toward the unlocking position to a certain extent, thereby increasing the stability of the locking member when it is in the locked position, and further increasing the stability of the electronic device.

[0016] Optionally, the locking part includes a positioning section and a locking section, at least a portion of the locking section protruding from the outer peripheral surface of the positioning section, and the elastic part is a spring sleeved on the outside of the positioning section, the spring abutting against the end face of the locking section away from the magnetic base.

[0017] By adopting the above technical solution, since the elastic part is a spring sleeved outside the positioning section, it can ensure the elastic driving effect of the elastic part on the locking part, and the positioning section can also be used to position and guide the spring to increase the stability of the elastic part. Furthermore, it can make the elastic force borne by the locking part in its circumferential direction more balanced to ensure the smooth sliding of the locking part. Since at least part of the locking part protrudes from the outer peripheral surface of the positioning section, and the spring abuts against the end face of the locking part away from the magnetic base, the end face of the locking part away from the magnetic base can block the spring to further increase the stability of the elasticity. On the other hand, the spring can also apply an elastic force towards the side where the magnetic base is located to the locking part through the end face of the locking part away from the magnetic base.

[0018] Optionally, the extended mounting bracket further includes a limiting rod located at the bottom of the fixing bracket, one end of the limiting rod is provided with a hook, the limiting rod is provided with a locking interface, and the fixing bracket has a mating block located in the locking interface.

[0019] By adopting the above technical solution, since one end of the limiting rod is equipped with a hook, when installing the limiting rod, the hook can be engaged with the defrost vent on the vehicle's dashboard to connect the limiting rod to the vehicle's dashboard. After the mounting bracket is installed on the vehicle's dashboard, the engagement of the mating block and the locking interface can limit the mounting bracket, preventing relative movement between the mounting bracket and the dashboard when the vehicle is traveling on bumpy roads. This increases the connection stability between the extension mounting bracket and the dashboard, thereby further increasing the stability of the electronic equipment.

[0020] Optionally, the extended mounting bracket further includes a cooling structure located at the bottom of the magnetic base. The cooling structure has a cooling channel inside, and one end of the cooling structure has an air inlet communicating with the cooling channel. The other end of the cooling structure has an air outlet communicating with the cooling channel. The air outlet is positioned facing the magnetic base, and the magnetic base is provided with a ventilation slot located between the mounting position and the air outlet.

[0021] By adopting the above technical solution, as the working time of electronic devices increases, the temperature of the electronic devices gradually rises. In order to ensure the stable operation of electronic devices, it is necessary to cool them down. When cooling electronic devices, the exhaust vent inside the vehicle can be connected to the air inlet of the cooling structure, so that the cold air discharged through the exhaust vent enters the cooling channel through the air inlet. The cold air in the cooling channel is discharged through the exhaust vent along the cooling channel. Since the exhaust vent is set towards the magnetic base, and the magnetic base is provided with a ventilation slot between the mounting position and the exhaust vent, the cold air discharged through the exhaust vent is directly blown onto the electronic device through the ventilation slot to achieve cooling of the electronic device.

[0022] When the vehicle is in extremely cold weather, the exhaust vents inside the vehicle can be connected to the air inlets of the cooling structure. This allows the hot air exhausted through the exhaust vents to enter the cooling channel through the air inlets. The hot air entering the cooling channel then flows through the cooling channel and is exhausted through the exhaust vents. This allows the hot air exhausted through the exhaust vents to be blown directly onto the electronic equipment through the ventilation slots, thereby warming up the electronic equipment and ensuring its normal operation.

[0023] In summary, the extension mounting bracket in this application can not only fix electronic devices, but also cool or heat them, thereby increasing the flexibility of the extension mounting bracket.

[0024] Optionally, the extended mounting bracket further includes a limiting rod with a hook at one end, the air inlet and the hook are both located at the same end of the limiting rod, and the air inlet is positioned away from the magnetic base.

[0025] By adopting the above technical solution, since the air inlet and the hook are both located at the same end of the limiting rod, and the air inlet is set away from the magnetic base, the extension mounting bracket is then installed on the vehicle's dashboard. The air inlet is positioned opposite to the defrost vent on the vehicle's dashboard, so that the air discharged through the defrost vent can directly enter the cooling channel through the air inlet. This allows the air discharged through the defrost vent to be used to cool or heat up the electronic equipment, thereby achieving automatic connection between the air inlet and the vehicle's internal air vents.

[0026] This application also discloses a vehicle to increase the ease of installing and removing electronic devices and to ensure the stability of electronic devices.

[0027] A vehicle includes an instrument panel and an extension mounting bracket as described above, the extension mounting bracket being disposed on the instrument panel and the mounting bracket being connected to the instrument panel via suction cups.

[0028] By adopting the above technical solution, since the vehicle in this application uses the aforementioned extended mounting bracket, the convenience of installing and removing electronic devices is improved on the one hand, and the stability of electronic devices is ensured on the other hand; since the mounting bracket is connected to the dashboard via suction cups, the extended mounting bracket can be fixedly connected to the dashboard using suction cups, thereby reducing the difficulty of fixing the extended mounting bracket.

[0029] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows: 1. The extended mounting bracket in this application includes a fixed bracket and a magnetic base connected to the fixed bracket. The magnetic base can magnetically attract ferromagnetic materials. The magnetic base has a mounting position for mounting electronic devices and a hand slot located at the bottom of the mounting position. The magnetic base can move relative to the fixed bracket to have a first position and a second position. When the magnetic base is in the second position, the hand slot and the fixed bracket are separated, thereby eliminating the need for tools when assembling and disassembling electronic devices, thus improving the convenience of assembling and disassembling electronic devices. At the same time, compared with the prior art of using adhesive to install electronic devices, it avoids the situation where the stability of electronic devices is affected as the installation time of electronic devices increases, thereby ensuring the stability of electronic devices.

[0030] 2. In this application, one of the mounting bracket and the magnetic base is provided with a sliding groove, and the other is provided with a sliding rail adapted to the sliding groove. The sliding rail is slidably connected to the sliding groove, thereby realizing the sliding connection between the magnetic base and the mounting bracket. At the same time, the sliding cooperation between the sliding rail and the sliding groove can guide the magnetic base to increase the stability of the magnetic base during sliding. The width of the groove opening is smaller than the width of the groove bottom, so the cooperation between the sliding rail and the sliding groove can limit the magnetic base to prevent the magnetic base from detaching from the mounting bracket in a direction perpendicular to its sliding direction. This increases the connection stability between the magnetic base and the mounting bracket, thereby further increasing the stability of the electronic device.

[0031] 3. The magnetic base in this application has a positioning piece located on the side of the mounting position. On the one hand, the positioning piece can be used to position the electronic device, so as to facilitate the staff to install the electronic device in place and further improve the installation efficiency of the electronic device. On the other hand, the positioning piece can also be used to limit the electronic device installed in the mounting position, so as to further increase the stability of the electronic device.

[0034] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.

[0035] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0036] Furthermore, it should be understood in the description of this application that the terms "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0037] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0038] In this application, unless otherwise expressly specified and limited, the "above" or "below" of the second feature can mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. In the description of this specification, references to terms such as "implementation," "example," "a particular embodiment," "example," or "specific example," etc., indicate that the specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples.

[0039] Reference Figures 1 to 5 An extended mounting bracket is disclosed, which includes a fixed frame 1 and a magnetic base 2 connected to the fixed frame 1. The magnetic base 2 is capable of magnetically attracting ferromagnetic materials. The magnetic base 2 has a mounting position for mounting electronic devices and a hand slot located at the bottom of the mounting position. The magnetic base 2 is capable of relative movement with the fixed frame 1 so that the magnetic base 2 has a first position and a second position. When the magnetic base 2 is in the second position, the hand slot avoids the fixed frame 1.

[0040] It is understandable that the magnetic holder 2 has a magnetic field, which enables the magnetic holder 2 to magnetically attract ferromagnetic materials; the electronic device is equipped with an iron sheet, which is ferromagnetic, so that the magnetic holder 2 can magnetically attract the electronic device.

[0041] It should be noted that, for the scheme in which the magnetic base 2 is slidably connected to the fixed frame 1, the aforementioned "the hand slot and the fixed frame 1 form a clearance" means that the hand slot can move to the side of the fixed frame 1 under the relative sliding action of the magnetic base 2 and the fixed frame 1, so that the worker's hand can be inserted into the hand slot; for the scheme in which the magnetic base 2 is hinged to the fixed frame 1, the aforementioned "the hand slot and the fixed frame 1 form a clearance" means that the hand slot can create a distance between itself and the fixed frame 1 under the relative rotation action of the magnetic base 2 and the fixed frame 1, so that a space for accommodating the worker's hand can be formed between the hand slot and the fixed frame 1.

[0042] When using the extended mounting bracket of this application to fix the electronic device, the extended mounting bracket is first installed inside the vehicle, that is, the fixing bracket 1 is fixedly installed inside the vehicle. Then, the electronic device is installed in the mounting position so that the iron piece on the electronic device is magnetically attracted to the magnetic base 2, thereby realizing the installation of the electronic device inside the vehicle. When disassembling the electronic device, the magnetic base 2 is operated first to move the magnetic base 2 from the first position to the second position, so that the hand slot and the fixing bracket 1 are separated. Then, the worker puts his hand into the hand slot and applies a force to separate the electronic device from the magnetic base 2, finally causing the iron piece on the electronic device to disengage from the magnetic base 2, thereby completing the disassembly of the electronic device.

[0043] In summary, compared to the prior art method of installing electronic devices inside a vehicle using fixed brackets, the extended mounting bracket in this application eliminates the need for tools when installing and removing electronic devices, thus improving the convenience of installation and removal. Compared to the prior art method of installing electronic devices by adhesive, it avoids the instability of electronic devices due to the increasing installation time, thereby ensuring the stability of the electronic devices. At the same time, the magnetic base 2 in this application can move relative to the fixed bracket 1, so that the magnetic base 2 can move to a second position where the hand slot and the fixed bracket 1 are in a non-collision position, so that the operator can put their hand into the hand slot to apply a force to separate the electronic device from the magnetic base 2, further facilitating the disassembly of the electronic device.

[0044] The electronic devices mentioned in this application can be not only data acquisition terminals used in the process of testing vehicles, but also other modules that need to be installed in vehicles, such as digital key modules.

[0045] This application does not specify the connection method between the magnetic base 2 and the fixing frame 1, and it can adopt any of the following embodiments: Implementation Method 1, in this implementation method, refer to Figures 1 to 5 The magnetic base 2 is slidably connected to the fixed frame 1. When disassembling the electronic device, the magnetic base 2 can be slidably moved between the first position and the second position, thereby reducing the difficulty of operating the magnetic base 2 when disassembling the electronic device and further achieving the effect of facilitating the disassembly of the electronic device.

[0046] It should be noted that in this embodiment, when the magnetic base 2 is in the first position, the magnetic base 2 is located directly above the fixing frame 1; while when the magnetic base 2 is in the second position, the end of the magnetic base 2 with the hand-receiving groove slides to the outside of the fixing frame 1.

[0047] This application does not specify the sliding connection method between the magnetic base 2 and the fixing frame 1. Preferably, refer to Figure 1 , Figure 2 and Figure 4 One of the fixed frame 1 and the magnetic base 2 is provided with a sliding groove 111, and the other is provided with a slide rail 211 adapted to the sliding groove 111. The slide rail 211 is slidably connected to the sliding groove 111, and the width of the groove opening of the sliding groove 111 is smaller than the width of the bottom of the sliding groove 111.

[0048] It should be noted that the above-mentioned matching of slide rail 211 and slide groove 111 means that the cross-sectional shape of slide rail 211 is the same as that of slide groove 111, and when slide rail 211 is located in slide groove 111, the outer peripheral surface of slide rail 211 contacts the groove wall of slide groove 111.

[0049] Since one of the fixed frame 1 and the magnetic base 2 is provided with a groove 111, and the other is provided with a slide rail 211 adapted to the groove 111, the slide rail 211 is slidably connected to the groove 111, thereby realizing the sliding connection between the magnetic base 2 and the fixed frame 1. At the same time, the sliding cooperation between the slide rail 211 and the groove 111 can guide the magnetic base 2 to increase the stability of the magnetic base 2 when sliding.

[0050] Furthermore, since the width of the groove opening of the slide 111 is smaller than the width of the bottom of the slide 111, and the slide rail 211 is adapted to the slide 111, the cooperation between the slide rail 211 and the slide 111 can also limit the magnetic base 2, so as to prevent the magnetic base 2 from detaching from the fixing frame 1 in a direction perpendicular to its own sliding direction, thereby increasing the connection stability between the magnetic base 2 and the fixing frame 1, and further increasing the stability of the electronic device.

[0051] This application does not specifically limit the structure of the slide 111; preferably, refer to... Figure 1 , Figure 2 and Figure 4 The slide groove 111 has a T-shaped cross-section, and the slide rail 211 also has a T-shaped cross-section to increase the stability of the sliding connection between the magnetic base 2 and the fixing frame 1. In other embodiments, the cross-sectional shapes of the slide groove 111 and the slide rail 211 can also be trapezoidal or other shapes, as long as the width of the opening of the slide groove 111 is less than the width of the bottom of the slide groove 111.

[0052] Preferably, the slide groove 111 is provided on the fixed frame 1, and the slide rail 211 is fixedly connected to the magnetic base 2, so that the slide rail 211 can be used to increase the structural strength of the magnetic base 2 and increase the stability of the magnetic base 2.

[0053] This application does not specify the exact location of the slide rail 211 and the slide groove 111. Preferably, refer to Figure 1 , Figure 2 and Figure 4 The magnetic base 2 has positioning pieces 21 located on opposite sides of the mounting position, and a slide rail 211 is fixedly connected to the positioning pieces 21. The fixing frame 1 has fixing rods 11 located on opposite sides of the magnetic base 2, and a slide groove 111 is provided on the fixing rods 11.

[0054] It is understood that there are two positioning pieces 21, which are located on opposite sides of the mounting position. There are also two fixing rods 11, which are located on opposite sides of the two fixing pieces 123. Each fixing rod 11 has a groove 111 on the side facing the positioning piece 21, and each fixing piece 123 has a slide rail 211 that is slidably connected in the groove 111 on the side facing the fixing rod 11.

[0055] Since the positioning piece 21 is located on opposite sides of the mounting position and the fixing rod 11 is located on opposite sides of the magnetic base 2, the slide rail 211 and the slide groove 111 can avoid the bottom of the magnetic base 2 so as to allow the hand to be inserted into the hand slot, thereby further facilitating the disassembly of the electronic device.

[0056] The better one is to refer to Figure 3 The groove 111 passes through one end of the fixed rod 11 along its length, and the length of the groove 111 is less than the length of the fixed rod 11, so that the other end of the fixed rod 11 along its length can block the slide rail 211, so as to prevent the magnetic seat 2 from sliding over and detaching from the other end of the fixed rod 11 along its length, thereby further increasing the connection stability between the magnetic seat 2 and the fixed frame 1.

[0057] In other implementation examples, the slide 111 may also be located at the bottom of the magnetic base 2, and the slide rail 211 may be fixedly connected to the bottom of the magnetic base 2.

[0058] In other embodiments, the top of the fixing frame 1 is provided with a connecting piece with an L-shaped cross section. There are two connecting pieces, and the two connecting pieces are located on opposite sides of the magnetic base 2. Each connecting piece forms an accommodating space with the fixing frame 1. The opposite sides of the magnetic base 2 are located in the two accommodating spaces, so as to realize the sliding connection between the magnetic base 2 and the fixing frame 1.

[0059] In the second embodiment, the magnetic base 2 has a first end and a second end opposite to the first end. The first end is hinged to the fixing frame 1. When disassembling the electronic device, the magnetic base 2 can be rotated to move from the first position to the second position, thereby reducing the difficulty of operating the magnetic base 2 when disassembling the electronic device and further achieving the effect of facilitating the disassembly of the electronic device.

[0060] Preferably, the hand slot is located at the second end of the magnetic base 2 to further facilitate the separation of the electronic device from the magnetic base 2.

[0061] It should be noted that, in this embodiment, when the magnetic base 2 is in the first position, the second end of the magnetic base 2 rests against the fixing frame 1 so that the fixing frame 1 supports the second end of the magnetic base 2; while when the magnetic base 2 is in the second position, the second end of the magnetic base 2 is separated from the fixing frame 1 so that the worker's hand can be inserted into the hand slot.

[0062] This application does not specifically limit the hinge method between the magnetic base 2 and the fixing frame 1. Preferably, the magnetic base 2 is provided with positioning pieces 21 located on opposite sides of the mounting position, and the fixing frame 1 is provided with fixing rods 11 located on opposite sides of the mounting position. The two fixing rods 11 are respectively located on opposite sides of the two positioning pieces 21. The fixing frame 1 also has hinge shafts passing through the two positioning pieces 21 and the two fixing rods 11 to realize the hinge between the magnetic base 2 and the fixing frame 1. In other embodiments, hinge shafts passing through the fixing rods 11 can also be provided on opposite sides of the two positioning pieces 21 to achieve the same hinge between the magnetic base 2 and the fixing frame 1.

[0063] In a preferred embodiment, refer to Figures 1 to 4 The magnetic base 2 has a positioning piece 21, which is located on the side of the mounting position.

[0064] It is understandable that there are two positioning pieces 21, with the two positioning pieces 21 located on opposite sides of the mounting position.

[0065] Since the positioning piece 21 is located on the side of the mounting position, it can be used to position the electronic device, making it easier for staff to install the electronic device in place and further improving the installation efficiency of the electronic device. On the other hand, the positioning piece 21 can also be used to limit the electronic device installed in the mounting position, thereby further increasing the stability of the electronic device.

[0066] In a preferred embodiment, refer to Figure 4 and Figure 5 The fixing frame 1 has a fixing rod 11 located on the side of the magnetic base 2. The fixing rod 11 is provided with a locking member 3. The magnetic base 2 has a locking groove 212. The locking member 3 can move relative to the fixing rod 11 so that the locking member 3 has a locking position that extends into the locking groove 212 and an unlocking position that disengages from the locking groove 212.

[0067] Since the locking member 3 is located on the fixing rod 11 and the locking groove 212 is located on the magnetic base 2, and the locking member 3 has a locking position that extends into the locking groove 212 and an unlocking position that disengages from the locking groove 212, the magnetic base 2 can be limited by the insertion and engagement of the locking member 3 and the locking groove 212 to increase the stability of the magnetic base 2 and prevent the magnetic base 2 from moving relative to the fixing frame 1 when the vehicle is driving on a bumpy road, thereby further increasing the stability of the electronic device. On the other hand, when disassembling the electronic device, the locking member 3 can be moved to the unlocking position by operating the locking member 3, so that the locking member 3 is separated from the locking groove 212, and the magnetic base 2 can move relative to the fixing frame 1, so as to ensure the convenience of disassembling the electronic device.

[0068] Preferably, two fixing rods 11 are provided, located on opposite sides of the mounting position. Each fixing rod 11 is provided with a locking element 3. Locking grooves 212 are provided on opposite sides of the magnetic base 2 corresponding to the locking element 3, thereby increasing the number of locking points for the magnetic base 2 and further enhancing its stability. Of course, in other embodiments, a locking element 3 can also be provided on one of the fixing rods 11 to facilitate unlocking of the magnetic base 2.

[0069] It should be noted that, for the above-mentioned scheme in which the magnetic base 2 is slidably connected to the fixed frame 1, the locking groove 212 can be set corresponding to the first position and the second position of the magnetic base 2. That is, when the magnetic base 2 is in the first position, the locking member 3 can extend into the locking groove 212 set corresponding to the first position to lock the magnetic base 2 in the first position. When the magnetic base 2 is in the second position, the locking member 3 can extend into the locking groove 212 set corresponding to the second position to lock the magnetic base 2 in the second position. Alternatively, the locking groove 212 can only be set corresponding to the first position of the magnetic base 2 to ensure the stability of the magnetic base 2 when it is in the first position. For the above-mentioned scheme in which the magnetic base 2 is hinged to the fixed frame 1, the insertion and engagement of the locking member 3 and the locking groove 212 only locks the first position of the magnetic base 2. That is, when the magnetic base 2 is in the first position, the locking member 3 and the locking groove 212 are engaged.

[0070] This application does not specifically limit the structure of the locking element 3; preferably, refer to... Figure 4 and Figure 5 The fixing rod 11 is provided with a through hole 112 and a receiving cavity 113 communicating with the through hole 112. The locking member 3 includes a locking part 31 passing through the through hole 112 and an elastic part 32 located in the receiving cavity 113. The elastic part 32 is used to apply an elastic force to the locking part 31 toward the side where the magnetic base 2 is located. When the locking member 3 is in the locked position, part of the locking part 31 extends into the locking groove 212.

[0071] It is understandable that when the locking member 3 is in the unlocked position, the elastic part 32 is in a deformed state.

[0072] When driving the locking member 3 toward the unlocking position, a pulling force is first applied to the locking part 31 in a direction away from the magnetic base 2, so that the locking part 31 moves relative to the fixing rod 11. At the same time, the locking part 31 compresses the elastic part 32, and the elastic part 32 undergoes elastic deformation, which finally causes the locking part 31 to separate from the locking groove 212, so as to complete the driving of the locking member 3 from the locking position to the unlocking position. In this process, only a pulling force needs to be applied to the locking part 31, thereby achieving the effect of easily driving the locking member 3 to the unlocking position.

[0073] When the locking member 3 needs to be moved to the locking position, the operator's hand only needs to be separated from the locking part 31. At this time, the elastic part 32 returns to its original shape, and the locking part 31 automatically moves toward the locking position under the action of the elastic part 32, thereby achieving the effect of easily driving the locking member 3 to the locking position.

[0074] Meanwhile, by providing the elastic part 32, when driving the locking member 3 toward the unlocking position, it is necessary to overcome the elastic force of the elastic part 32, which to a certain extent increases the force required for the locking member 3 to move toward the unlocking position, thereby increasing the stability of the locking member 3 when it is in the locked position, and further increasing the stability of the electronic device.

[0075] This application does not specifically limit the structure of the locking part 31 and the elastic part 32. Preferably, refer to Figure 4 and Figure 5 The locking part 31 includes a positioning section 311 and a locking section 312. At least a portion of the locking section 312 protrudes from the outer peripheral surface of the positioning section 311. The elastic part 32 is a spring sleeved on the outside of the positioning section 311. The spring abuts against the end face of the locking section 312 away from the magnetic base 2.

[0076] It is understandable that the positioning section 311 is located at the end of the locking section 312 away from the magnetic base 2, and the end of the spring away from the locking section 312 abuts against the cavity wall of the receiving cavity 113 away from the magnetic base 2; when the locking member 3 is in the locked position, part of the locking section 312 extends into the locking groove 212.

[0077] Since the elastic part 32 is a spring sleeved outside the positioning section 311, it can ensure the elastic driving effect of the elastic part 32 on the locking part 31, and the positioning section 311 can also be used to position and guide the spring to increase the stability of the elastic part 32. Furthermore, it can make the elastic force borne by the locking part 31 in its own circumferential direction more balanced to ensure the smooth sliding of the locking part 31.

[0078] Furthermore, since at least a portion of the locking section 312 protrudes from the outer peripheral surface of the positioning section 311, and the spring abuts against the end face of the locking section 312 away from the magnetic base 2, the end face of the locking section 312 away from the magnetic base 2 can block the spring, thereby further increasing the stability of the elasticity. On the other hand, the spring can also apply an elastic force toward the side where the magnetic base 2 is located to the locking part 31 through the end face of the locking section 312 away from the magnetic base 2.

[0079] This application does not specifically limit the structure of the locking section 312 and the positioning section 311. Preferably, the locking section 312 is a block structure with a square cross-section, and the positioning section 311 is a columnar structure with a circular cross-section. The through hole 112 includes a first section located at the end of the receiving cavity 113 near the magnetic base 2 and a second section located at the end of the receiving section away from the magnetic base 2. The shape of the first section is adapted to the shape of the locking section 312, and the shape of the second section is adapted to the shape of the positioning section 311, so that the locking section 312 can be engaged with the hole wall of the first section to limit the rotation of the locking part 31. The width of the locking section 312 is greater than or equal to the diameter of the positioning section 311, so that at least a portion of the locking section 312 protrudes from the outer peripheral surface of the positioning section 311. In other embodiments, both the positioning section 311 and the locking section 312 can also be columnar structures with a circular cross-section, and the diameter of the locking section 312 is greater than the diameter of the positioning section 311.

[0080] In other embodiments, the locking part 31 is a columnar structure, and an annular rib located in the accommodating cavity 113 is provided in the middle of the length direction of the locking part 31. The elastic part 32 is a spring sleeved on the outside of the locking part 31, and the end of the spring near the magnetic base 2 abuts against the annular rib; or, the locking part 31 is a columnar structure, the elastic part 32 is an elastic sheet, one end of the elastic sheet is fixedly connected to the middle of the length direction of the locking part 31, and the other end of the elastic sheet contacts the cavity wall of the accommodating cavity 113 away from the magnetic base 2.

[0081] In other embodiments, the fixing rod 11 is provided with a threaded hole, and the locking member 3 is a screw threaded to the threaded hole, so that the locking member 3 can be switched between the locked position and the unlocked position by rotating the screw; or, the locking member 3 is a rod-shaped structure passing through the fixing rod 11, so that the locking member 3 can be switched between the locked position and the unlocked position by sliding the locking member 3.

[0082] The better one is to refer to Figure 5 The locking component 3 is provided with a hand block 313 located on the side of the fixing rod 11 away from the magnetic base 2 at the end away from the magnetic base 2. The diameter of the hand block 313 is larger than the diameter of the locking component 3, so as to facilitate the operation of the locking component 3 by the staff.

[0083] In the case of the magnetic base 2 being slidably connected to the fixed frame 1, the locking groove 212 is provided on the slide rail 211; in the case of the magnetic base 2 being hinged to the fixed frame 1, the locking groove 212 is provided on the positioning piece 21.

[0084] This application does not specify the fixing method of the fixing bracket 1. Preferably, refer to Figures 1 to 4 The mounting bracket 1 is equipped with suction cups 115, which can be used to fix the extension mounting bracket to the inside of the vehicle by negative pressure adsorption, thereby reducing the difficulty of fixing the extension mounting bracket. Multiple suction cups 115 are arranged at intervals along the circumference of the mounting bracket 1, thereby increasing the connection points between the extension mounting bracket and the vehicle, and increasing the connection stability between the extension mounting bracket and the vehicle.

[0085] Furthermore, refer to Figures 1 to 4 The extended mounting bracket also includes a limiting rod 4 located at the bottom of the fixed frame 1. One end of the limiting rod 4 is provided with a hook 41, and the limiting rod 4 is provided with a locking interface 42. The fixed frame 1 has a mating block 121 located in the locking interface 42.

[0086] Because one end of the limiting rod 4 is provided with a hook 41, when the limiting rod 4 is installed, the hook 41 can be engaged with the defogger vent 61 on the vehicle dashboard 6 to connect the limiting rod 4 to the vehicle dashboard 6. This allows the mounting bracket 1 to be installed on the vehicle dashboard 6, so that the suction cup 115 is negatively attracted to the vehicle dashboard 6. The mounting bracket 1 is limited by the cooperation of the mating block 121 and the locking interface 42 to prevent the mounting bracket 1 from moving relative to the dashboard 6 when the vehicle is driving on bumpy roads. This ensures the stability of the negative pressure attraction between the suction cup 115 and the dashboard 6, thereby increasing the connection stability between the extension mounting bracket and the dashboard 6 and further increasing the stability of the electronic equipment.

[0087] Preferably, there are two limiting rods 4, which are arranged in parallel and spaced apart to increase the number of limiting points on the fixing frame 1, thereby further increasing the stability of the fixing frame 1.

[0088] Preferably, the hook 41 is an L-shaped rod structure fixedly connected to the limiting rod 4, and the diameter of the rod structure constituting the hook 41 is equal to the width of the defogging vent 61 on the instrument panel 6. When installing the limiting rod 4, first place the limiting rod 4 parallel to the direction in which the multiple defogging vents 61 are arranged in sequence, and then lower the limiting rod 4 so that the hook 41 extends into the defogging vent 61. Then rotate the limiting rod 4 so that the limiting rod 4 is perpendicular to the direction in which the multiple defogging vents 61 are arranged in sequence. At this time, one end of the hook 41 is located at the bottom of the defogging vent 61 and cooperates with the wall stop between two adjacent defogging vents 61.

[0089] This application does not specify the formation method of the mating block 121; preferably, refer to Figure 3 The fixing frame 1 includes a fixing rod 11 and a support rod 12 located at the bottom of the fixing rod 11. The support rod 12 is vertically fixed to the fixing rod 11. The end of the support rod 12 is provided with a notch, and a mating block 121 is formed at the notch. Two limiting rods 4 are respectively located at both ends of the support rod 12 to limit the fixing frame 1 in the length direction of the fixing rod 11 and the length direction of the support rod 12, so as to further increase the stability of the fixing frame 1.

[0090] In other embodiments, the mating block 121 may also be formed as a block structure separately provided on the fixing frame 1.

[0091] The better one is to refer to Figures 1 to 4 The fixing rod 11 is provided with an extension rod 114 parallel to the support rod 12. The suction cup 115 is located at the bottom of the extension rod 114 and is located on the side opposite to each other of the two limiting rods 4, so that the suction cup 115 can block the limiting rods 4 to increase the stability of the limiting rods 4.

[0092] In other embodiments, the mounting bracket 1 can also be fixed to the vehicle's dashboard 6 by bolts or screws.

[0093] In a preferred embodiment, refer to Figures 1 to 3 The extended mounting bracket also includes a cooling structure 5 located at the bottom of the magnetic base 2. The cooling structure 5 has a cooling channel inside, and one end of the cooling structure 5 has an air inlet communicating with the cooling channel. The other end of the cooling structure 5 has an air outlet communicating with the cooling channel. The air outlet is set towards the magnetic base 2. The magnetic base 2 is provided with a ventilation slot located between the mounting position and the air outlet.

[0094] As the operating time of electronic devices increases, their temperature gradually rises. To ensure stable operation, it is necessary to cool them down. To cool them down, the exhaust vent inside the vehicle can be connected to the air inlet of the cooling structure 5. This allows the cold air exhausted through the exhaust vent to enter the cooling channel through the air inlet. The cold air in the cooling channel flows along the channel and is exhausted through the exhaust vent. Since the exhaust vent faces the magnetic base 2, and the magnetic base 2 has a ventilation slot between the mounting position and the exhaust vent, the cold air exhausted through the exhaust vent is directly blown onto the electronic device through the ventilation slot, thus cooling the electronic device.

[0095] When the vehicle is in extremely low temperatures, the exhaust vent inside the vehicle can be connected to the air inlet of the cooling structure 5, so that the hot air discharged through the exhaust vent enters the cooling channel through the air inlet. The hot air entering the cooling channel flows along the cooling channel and is discharged through the exhaust vent, so that the hot air discharged through the exhaust vent blows directly to the electronic equipment through the ventilation slot, thereby warming up the electronic equipment and ensuring the normal operation of the electronic equipment.

[0096] In summary, the extension mounting bracket in this application can not only fix electronic devices, but also cool or heat them, thereby increasing the flexibility of the extension mounting bracket.

[0097] This application does not specify the air intake method of the air inlet. Preferably, the extended mounting bracket also includes a limiting rod 4 with a hook 41 at one end. The air inlet and the hook 41 are both located at the same end of the limiting rod 4, and the air inlet is positioned away from the magnetic base 2.

[0098] Understandably, the vehicle's defrosting system supplies air to the air intake.

[0099] Since the air inlet and the hook 41 are both located at the same end of the limiting rod 4, and the air inlet is set away from the magnetic base 2, after the extension mounting bracket is installed on the vehicle's dashboard 6, the air inlet is set opposite to the defogger vent 61 on the vehicle's dashboard 6, so that the air discharged through the defogger vent 61 can directly enter the cooling channel through the air inlet, so as to use the air discharged through the defogger vent 61 to cool or heat up the electronic equipment, thereby realizing the automatic connection between the air inlet and the vehicle's internal air vent.

[0100] In other embodiments, the extension mounting bracket also includes a cooling fan to provide air to the air intake; or, the air intake is connected via a duct to the exhaust vent of the vehicle's air conditioning system to provide air to the air intake using the vehicle's air conditioning system.

[0101] This application does not specifically limit the cooling structure 5; however, preferred options are described below. Figure 3 The cooling structure 5 includes an air inlet box 51, an air outlet box 52, and a connecting pipe 53 connecting the air inlet box 51 and the air outlet box 52. The air inlet is located in the air inlet box 51, and the air outlet is located in the air outlet box 52.

[0102] It is understandable that the internal spaces of the air inlet box 51, the air outlet box 52, and the connecting pipe 53 together form a cooling channel.

[0103] Since the air inlet is located in the air inlet box 51, the air inlet area of ​​the cooling structure 5 is increased, thereby improving the air intake efficiency of the cooling channel. Since the air outlet is located in the air outlet box 52, the air outlet area of ​​the cooling structure 5 is increased, thereby improving the cooling or heating efficiency of electronic equipment.

[0104] Preferably, the bottom of the air inlet box 51 is open, which can reduce the manufacturing difficulty of the air inlet box 51 and further increase the air inlet area; the top of the air outlet box 52 is open, which can reduce the manufacturing difficulty of the air outlet box 52 and further increase the air outlet area.

[0105] This application does not limit the connection method between the air inlet box 51 and the air outlet box 52 and the connecting pipe 53. Preferably, both the air inlet box 51 and the air outlet box 52 are fixedly connected to the connecting pipe 53 to increase the connection stability between the air inlet box 51 and the air outlet box 52 and the connecting pipe 53. In other embodiments, both the air inlet box 51 and the air outlet box 52 can also be plugged into the connecting pipe 53.

[0106] In other embodiments, the cooling structure 5 may also be formed by a pipe structure, with one end of the pipe structure bent toward the direction of the mounting position; the cooling structure 5 may even be other structures, as long as it can deliver air and the air outlet is toward the mounting position.

[0107] This application does not specify the fixing method of the cooling structure 5; preferably, refer to... Figure 3 The mounting bracket 1 is provided with a support rod 12, and the support rod 12 is provided with a receiving groove 122. A portion of the cooling structure 5 is located in the receiving groove 122, and the support rod 12 is fixedly connected to a fixing plate 123 by bolts or screws. The fixing plate 123 is located at the opening of the receiving groove 122 to fix the cooling structure 5. In other embodiments, the cooling structure 5 can also be fixedly connected to the bottom of the magnetic base 2.

[0108] This application does not specifically limit the formation method of the hand-holding groove and the ventilation groove; preferably, refer to Figure 1 and Figure 2 The magnetic base 2 includes two spaced-apart support plates 22. The space between the two support plates 22 forms a hand-receiving groove and a ventilation groove to increase the volume of the hand-receiving groove and the ventilation groove. In other embodiments, the magnetic base 2 includes a plate structure with two groove-shaped structures. Both groove-shaped structures penetrate the plate structure in the thickness direction, so that the two groove-shaped structures respectively form a hand-receiving groove and a ventilation groove.

[0109] This application does not specifically limit the structure of the magnetic base 2; preferably, refer to... Figures 1 to 3 The magnetic base 2 includes two support pieces 22 and two positioning pieces 21. The positioning pieces 21 are arranged in a one-to-one correspondence with the support pieces 22. Each positioning piece 21 and its corresponding support piece 22 together form an L-shaped wall structure, and the top of the two support pieces 22 forms an installation position.

[0110] Furthermore, refer to Figures 1 to 3 The magnetic base 2 also includes a connecting piece 23, the two ends of which are fixedly connected to two support pieces 22 to connect the two support pieces 22 into one, thereby increasing the integrity of the magnetic base 2 and further facilitating the disassembly of electronic devices.

[0111] This application does not specifically limit the formation method of the magnetic holder 2 to magnetically attract ferromagnetic materials. Preferably, the support piece 22 is formed of a magnet to increase the magnetic attraction area with the electronic device, thereby further increasing the stability of the electronic device. In other embodiments, the support piece 22 is embedded with a magnet to enable the magnetic holder 2 to magnetically attract ferromagnetic materials; or, the positioning piece 21 is formed of a magnet, both the support piece 22 and the positioning piece 21 are formed of magnets, or the positioning piece 21 is embedded with a magnet.

[0112] The better one is to refer to Figures 1 to 3 Each of the two support plates 22 is provided with a blocking plate 221 at one end near the air inlet. The blocking plate 221 is located on the top of the support plate 22 so that the electronic device can be blocked and positioned, thereby facilitating the installation of the electronic device and further increasing the connection stability between the electronic device and the magnetic base 2.

[0113] In other embodiments, the magnetic base 2 may also be composed of a plate-like structure.

[0114] Reference Figure 6 and Figure 7 This application also discloses a vehicle including an instrument panel 6 and an extension mounting bracket as described above, the extension mounting bracket being disposed on the instrument panel 6, and the mounting bracket 1 being connected to the instrument panel 6 via a suction cup 115.

[0115] Because the vehicle in this application uses the aforementioned extended mounting bracket, it improves the convenience of installing and removing electronic devices while ensuring the stability of the electronic devices.

[0116] In a preferred embodiment, refer to Figure 7 Multiple defogger vents 61 are provided on the top of the dashboard 6 near the front of the vehicle. The multiple defogger vents 61 are arranged sequentially along the width of the vehicle. The hook 41 extends into one of the defogger vents 61 and cooperates with the wall stop between two adjacent defogger vents 61. Multiple suction cups 115 are negatively attached to the top of the dashboard 6 to increase the connection stability between the extension mounting bracket and the vehicle.
