Patent Description:
At present, electronic devices such as a router, a camera, and an antenna may be fastened on existing rod bodies such as a railing, a fence, a downpipe, and a lamp post by using hoops.

For example, <FIG> shows a hoop <NUM> in the conventional technology. As shown in <FIG>, the hoop <NUM> includes a steel belt <NUM> and a steel belt buckle <NUM>, the steel belt <NUM> is provided with a plurality of fastening holes <NUM> in a length direction, one end of the steel belt <NUM> is connected to the steel belt buckle <NUM>, and the steel belt buckle <NUM> can be connected to any fastening hole <NUM>. In this way, by fastening the steel belt buckle <NUM> to different fastening holes <NUM>, the hoop <NUM> can be tightly held onto rod bodies <NUM> with a plurality of cross-sectional sizes (as shown in <FIG>). However, because there is a specific spacing between two adjacent fastening holes <NUM>, a scope of the rod bodies <NUM> to which the hoop <NUM> shown in <FIG> is applicable is still limited. The hoop <NUM> is not tightly held onto rod bodies of some diameters when being fastened on the rod bodies, resulting in a poor fastening effect.

IT <CIT> discloses a universal support device with elastic band, adjustable and removable, for fixing portable electronic equipment, in one case to the handlebar of a vehicle of the motor vehicle or bicycle type, or even in correspondence with a flat surface of a vehicle.

<CIT> discloses a spacer for spacing apart two attached articles, particularly for spacing apart bicycles from each other or other articles such as racks to protect the articles.

Embodiments of this application provide a hoop and an electronic device, to increase a scope of rod bodies to which the hoop is applicable.

Advantageous features are defined in the dependent claims.

According to a first aspect, an embodiment of this application provides a hoop, including a strap, a strap buckle, a support member, and a driving member. The strap is provided with a plurality of fastening holes in a length direction. The strap buckle includes a buckle head, a buckle body, and a buckle tail, the buckle head and the buckle tail are respectively located on two sides of the buckle body and are connected to the buckle body, the buckle tail is connected to one end of the strap, and the buckle head is capable of being fastened to any one of the fastening holes, so that the strap is held onto an existing rod body. The support member is located on a side that is of the buckle body and that is configured to face the existing rod body, the driving member is connected between the support member and the buckle body, and the driving member is configured to drive the support member to move in a direction close to or away from the buckle body.

In the hoop provided in this embodiment of this application, the hoop includes the strap and the strap buckle, the strap is provided with the plurality of fastening holes in the length direction, the strap buckle includes the buckle head, the buckle body, and the buckle tail, the buckle head and the buckle tail are respectively located on the two sides of the buckle body and are connected to the buckle body, the buckle tail is connected to one end of the strap, and the buckle head is capable of being fastened to any one of the fastening holes, so that the strap is held onto the existing rod body. In addition, the hoop includes the support member and the driving member, the support member is located on the side that is of the buckle body and that is configured to face the existing rod body, the driving member is connected between the support member and the buckle body, and the driving member is configured to drive the support member to move in the direction close to or away from the buckle body. Therefore, by fastening the buckle head to different fastening holes, the hoop can be directly held tightly onto rod bodies with a plurality of cross-sectional sizes defined by the plurality of fastening holes. When a cross-sectional size of a rod body is different from any one of the plurality of cross-sectional sizes, the strap may wind around the rod body, and the buckle head may be fastened to a fastening hole, so that the strap is held onto the rod body; and then the driving member drives the support member to move in the direction away from the buckle body to press the rod body, so that the strap is tightly held onto the rod body. In this way, the hoop can be tightly held onto the rod body with the cross-sectional size other than the plurality of cross-sectional sizes, thereby increasing a scope of rod bodies to which the hoop is applicable.

With reference to the first aspect, in a first optional implementation of the first aspect, the driving member is a hand torsion bar, and the hand torsion bar includes a hand torsion part, a screw rod part, and a connecting part that are successively connected in a length direction. The buckle body is provided with a threaded hole, the hand torsion part is located on a side that is of the buckle body and that is away from the support member, the screw rod part is screwed into the threaded hole, and the connecting part is connected to the support member. In this way, the hand torsion part can be operated to drive the support member to move in the direction close to or away from the buckle body. Such a driving member has a simple structure, a small footprint, and low costs.

With reference to the first optional implementation of the first aspect, in a second optional implementation of the first aspect, the connecting part is rotatably connected to the support member, and an axis of rotation between the connecting part and the support member is collinear with a central axis of the screw rod part. In this way, the support member is not fastened to the connecting part, and when the hand torsion bar is rotated to drive the support member to press the rod body, the support member is not rotated together with the hand torsion bar under the friction action of the rod body. This can avoid friction and wear between the support member and the rod body caused when the rod body is pressed.

With reference to the second optional implementation of the first aspect, in a third optional implementation of the first aspect, a limiting structure is disposed between the support member and the buckle body, and the limiting structure allows the support member to move in the direction close to or away from the buckle body and prevents the support member from rotating relative to the buckle body. In this way, when the hand torsion bar is rotated, the limiting structure can prevent the support member from rotating relative to the buckle body. This avoids friction between the support member and the rod body caused when the rod body is pressed.

With reference to the third optional implementation of the first aspect, in a fourth optional implementation of the first aspect, the limiting structure includes a square limiting hole and a limiting protrusion, one of the square limiting hole and the limiting protrusion is disposed on the buckle body, the other one of the square limiting hole and the limiting protrusion is disposed on the support member, an axial direction of the square limiting hole is the same as that of the screw rod part, the limiting protrusion is accommodated in the square limiting hole and is capable of sliding along the axial direction of the square limiting hole, the limiting protrusion has a first side surface and a second side surface, and the first side surface and the second side surface respectively fit in with two opposite inner walls of the square limiting hole. By making the limiting protrusion slide along the axial direction of the square limiting hole, the limiting structure allows the support member to move in the direction close to or away from the buckle body; and by making the two inner side surfaces of the square limiting hole fit in with the first side surface and the second side surface of the limiting protrusion, the limiting structure prevents the limiting protrusion from rotating in the square limiting hole, to prevent the support member from rotating relative to the buckle body. Such a limiting structure is simple and is easy to implement.

With reference to any one of the first aspect to the fourth optional implementation of the first aspect, in a fifth optional implementation of the first aspect, a strap hole is disposed on the buckle head, the strap hole allows the strap to pass through, a hook-up is disposed on an inner wall of the strap hole, and the fastening hole is capable of being hung on the hook-up. In this way, the strap passes through the strap hole, and the buckle head is fastened to the fastening hole by hanging the fastening hole on the hook-up. Such a structure is simple and is convenient to operate.

With reference to any one of the first aspect to the fifth optional implementation of the first aspect, in a sixth optional implementation of the first aspect, the hoop further includes an elastic pad. The elastic pad is disposed at least at an end that is of the support member and that is away from the buckle body. In this way, when the driving member drives the support member to move in the direction away from the buckle body to press the rod body, the elastic pad comes into contact with the rod body. This avoids compressive deformation of the rod body.

With reference to the sixth optional implementation of the first aspect, in a seventh optional implementation of the first aspect, a surface that is of the elastic pad and that is away from the buckle body is provided with an anti-slide structure. In this way, when the hoop in this embodiment of this application is tightly held onto the rod body, the anti-slide structure on the elastic pad comes into contact with the rod body. This can prevent the hoop from sliding down along the rod body.

With reference to the sixth or the seventh optional implementation of the first aspect, in an eighth optional implementation of the first aspect, the surface that is of the elastic pad and that is away from the buckle body is a first profiling surface, and the first profiling surface is adapted to a surface of the rod body. In this way, when the hoop in this embodiment of this application is tightly held onto the rod body, the first profiling surface fits in with the surface of the rod body, and a fitting area is large, so that a pressing force between the elastic pad and the rod body acts on a larger surface. This avoids compressive deformation of the rod body.

With reference to any one of the first aspect to the eighth optional implementation of the first aspect, in a ninth optional implementation of the first aspect, the hoop further includes at least one strap accommodation member, each strap accommodation member is provided with first through holes and second through holes, the first through holes and the second through holes are arranged side by side, the strap accommodation member is disposed, through the first through holes, on a part that is of the strap and that is configured to hold onto the existing rod body, and a part that is of the strap and that is not configured to hold onto the existing rod body is capable of being disposed through the second through holes. In this way, the strap accommodation member accommodates the part that is of the strap and that is not configured to hold onto the existing rod body, appearance neatness of the hoop that is present after the hoop is fastened on the rod body is ensured. In addition, the strap accommodation member can slide along the length direction of the strap, to adjust a location of the strap accommodation member, so that the strap accommodation member can accommodate parts of the strap that have different lengths and that are not configured to hold onto the existing rod body.

With reference to the ninth optional implementation of the first aspect, in a tenth optional implementation of the first aspect, a surface that is of the strap accommodation member and that is configured to fit in with the existing rod body is provided with an anti-slide structure. In this way, when the hoop in this embodiment of this application is tightly held onto the rod body, the anti-slide structure on the strap accommodation member comes into contact with the rod body. This can prevent the hoop from sliding down along the rod body.

With reference to the ninth or the tenth optional implementation of the first aspect, in an eleventh optional implementation of the first aspect, the surface that is of the strap accommodation member and that is configured to fit in with the existing rod body is a second profiling surface, and the second profiling surface is adapted to the surface of the rod body. In this way, when the hoop in this embodiment of this application is tightly held onto the rod body, the second profiling surface fits in with the surface of the rod body, and a fitting area is large, so that a pressing force between the strap accommodation member and the rod body acts on a larger surface. This avoids damage to the strap accommodation member and the rod body during mutual pressing.

With reference to the ninth, the tenth, or the eleventh optional implementation of the first aspect, in a twelfth optional implementation of the first aspect, a material of the strap accommodation member is silica gel. Silica gel has high toughness and can be prevented from being scratched by the strap when sliding along the strap.

With reference to any one of the first aspect to the twelfth optional implementation of the first aspect, in a thirteenth optional implementation of the first aspect, a thickness of the strap is <NUM> to <NUM>. In this way, a minimum bending radius of the strap is small, and the strap can be tightly held onto a rod body whose cross section is rectangular, triangular, prismatic, or the like.

With reference to any one of the first aspect to the thirteenth optional implementation of the first aspect, in a fourteenth optional implementation of the first aspect, a material of the strap is <NUM> stainless steel. <NUM> stainless steel has high tensile strength and is resistant to corrosion and a high temperature, and a lifespan of the strap is long.

According to a second aspect, an embodiment of this application provides an electronic device, including an electronic device body and the hoop according to any one of the foregoing technical solutions. A base of the electronic device body is provided with a third through hole, and the electronic device body is disposed on the strap through the third through hole.

Because the hoop used in the electronic device in this embodiment of this application is the same as the hoop according to the foregoing technical solutions, the two hoops can resolve a same technical problem and achieve a same expected effect.

With reference to the second aspect, in a first optional implementation of the second aspect, the electronic device body is an outdoor wireless router.

Electronic devices such as an outdoor wireless router and a road surveillance camera are widely deployed in outdoor scenarios to implement wireless sharing, traffic violation capture, and traffic flow monitoring within a specific range. Specifically, the electronic devices may be fastened on existing rod bodies in outdoor scenarios, to reduce deployment costs of the electronic devices. For example, the electronic devices may be fastened on existing rod bodies such as a lamp post, a railing, a fence, and a downpipe. To make weights of the existing rod bodies (for example, a railing and a fence) light, or to make fluid media capable of being transmitted or electrical connection cables capable of being deployed inside the existing rod bodies (for example, a downpipe and a lamp post), the existing rod bodies usually have hollow structures with small wall thicknesses. If the electronic devices are connected to the existing rod bodies by using threaded connectors (for example, a bolt and a screw), holes need to be drilled on the rod bodies. Consequently, liquid media in the rod bodies leak, and structural strength of the rod bodies is greatly reduced. In addition, because the wall thicknesses of the existing rod bodies are small, threaded fitting sizes between the threaded connectors and the existing rod bodies are small, and the electronic devices cannot be securely connected to the rod bodies. If the electronic devices are connected to the existing rod bodies through welding, heat generated during welding is prone to damage the electronic devices. Moreover, the electronic devices are in line contact with the existing rod bodies, a welding area is small, an operation is difficult, and welding strength is low.

To avoid the foregoing problems, an electronic device may be fastened on an existing rod body by using a hoop. The hoop includes a strap and a strap buckle, the strap is provided with a plurality of fastening holes along a length direction, one end of the strap is connected to the strap buckle, and the strap buckle is capable of being fastened to any one of the fastening holes, so that the strap is held onto an existing rod body. The electronic device is disposed on a part that is of the strap and that is held onto the existing rod body, so that the electronic device is fastened on the existing rod body. However, because there is a specific spacing between two adjacent fastening holes, a scope of rod bodies to which the hoop is applicable is limited. The hoop is not tightly held onto rod bodies of some diameters when being fastened on the rod bodies, resulting in a poor fastening effect.

In view of this, some embodiments of this application provide an electronic device (as shown in <FIG>), including an electronic device body <NUM> and a hoop <NUM>. The electronic device body <NUM> includes but is not limited to an outdoor wireless router or a road surveillance camera. In some embodiments, as shown in <FIG>, the electronic device body <NUM> is an outdoor wireless router.

In addition, the hoop <NUM> includes the support member <NUM> and the driving member <NUM>, the support member <NUM> is located on the side that is of the buckle body <NUM> and that is configured to face the existing rod body, the driving member <NUM> is connected between the support member <NUM> and the buckle body <NUM>, and the driving member <NUM> is configured to drive the support member <NUM> to move in the direction close to or away from the buckle body <NUM>. Therefore, by fastening the buckle head <NUM> to different fastening holes <NUM>, the hoop <NUM> carrying the electronic device can be directly held tightly onto rod bodies <NUM> with a plurality of cross-sectional sizes defined by the plurality of fastening holes <NUM> (as shown in <FIG>). When a cross-sectional size of a rod body is different from any one of the plurality of cross-sectional sizes, without changing a spacing between two adjacent fastening holes <NUM> on the strap <NUM>, the buckle body <NUM> may be used as a reference after the strap <NUM> is held onto the rod body <NUM> by using the strap buckle <NUM>. The driving member <NUM> drives the support member <NUM> to move in the direction away from the buckle body <NUM>, so that the support member <NUM> presses the rod body <NUM>, and the strap <NUM> is tightly held onto the rod body <NUM>. In this way, the hoop <NUM> can be tightly held onto the rod body with the cross-sectional size other than the plurality of cross-sectional sizes, thereby increasing a scope of rod bodies to which the hoop <NUM> is applicable.

Because the hoop <NUM> used in the electronic device in this embodiment of this application is the same as the hoop <NUM> according to the foregoing technical solutions, the two hoops <NUM> can resolve a same technical problem and achieve a same expected effect.

As shown in <FIG> or <FIG>, one end of the strap <NUM> winds around the rotating shaft <NUM> and is then bent reversely, and is fixedly connected to a part that is of the strap <NUM> and that does not wind around the rotating shaft <NUM>, so that the strap <NUM> can rotate around the rotating shaft <NUM>. This facilitates adjustment of an angle of the strap <NUM> relative to the strap buckle <NUM>, so that the strap <NUM> fits in with a surface of the to-be-held rod body, so as to be tightly held onto the to-be-held rod body. In some embodiments, the part that is of the strap <NUM> and that winds around the rotating shaft <NUM> and the part that is of the strap <NUM> and that does not wind around the rotating shaft <NUM> are fixedly connected to each other by using at least one rivet <NUM>. Surface flatness that is present after riveting is performed by using the rivet <NUM> is desirable, and no sharp protrusion appears.

This enables a convenient operation and desirable appearance neatness.

A material of the support member <NUM> includes but is not limited to metal, plastic, silica gel, or rubber. The support member <NUM> may be entirely made of a rigid material, or may be entirely made of an elastic material, or may be partially made of a rigid material and partially made of an elastic material.

In some embodiments, as shown in <FIG> or <FIG>, the hoop <NUM> further includes an elastic pad <NUM>. The elastic pad <NUM> is disposed at least at an end that is of the support member <NUM> and that is away from the buckle body <NUM>. In this way, when the driving member <NUM> drives the support member <NUM> to move in the direction away from the buckle body <NUM> to press the rod body, the elastic pad <NUM> comes into contact with the rod body. This avoids compressive deformation of the rod body.

In the foregoing embodiment, that the elastic pad <NUM> is disposed at least at an end that is of the support member <NUM> and that is away from the buckle body <NUM> means: The elastic pad <NUM> may be disposed only at the end that is of the support member <NUM> and that is away from the buckle body <NUM>, or may be disposed at the end that is of the support member <NUM> and that is away from the buckle body <NUM> and disposed at another part of the support member <NUM>. This is not specifically limited herein. In some embodiments, as shown in <FIG>, the elastic pad <NUM> is disposed only at the end that is of the support member <NUM> and that is away from the buckle body <NUM>. In some other embodiments, as shown in <FIG>, the elastic pad <NUM> is disposed at the end that is of the support member <NUM> and that is away from the buckle body <NUM> and disposed on a side surface of the support member <NUM>. That the elastic pad <NUM> is disposed at the end that is of the support member <NUM> and that is away from the buckle body <NUM> specifically means: The elastic pad <NUM> may cover an entire end surface of the end that is of the support member <NUM> and that is away from the buckle body <NUM> (as shown in <FIG> or <FIG>), or cover only a partial end face of the end that is of the support member <NUM> and that is away from the buckle body <NUM>. For example, the elastic pad <NUM> covers only an edge region of the end face of the end that is of the support member <NUM> and that is away from the buckle body <NUM>. This is not specifically limited herein.

In some embodiments, as shown in <FIG>, a surface that is of the elastic pad <NUM> and that is away from the buckle body <NUM> is provided with an anti-slide structure a. In this way, when the hoop <NUM> in this embodiment of this application is tightly held onto the rod body, the anti-slide structure a on the elastic pad <NUM> comes into contact with the rod body.

There are a plurality of structural forms for the anti-slide structure a. This is not specifically limited herein. In some embodiments, as shown in <FIG>, the anti-slide structure a is a plurality of ribs uniformly disposed on the surface that is of the elastic pad <NUM> and that is away from the buckle body <NUM>, and the plurality of ribs are arranged intersecting each other.

In some embodiments, the surface that is of the elastic pad <NUM> and that is away from the buckle body <NUM> is a first profiling surface, and the first profiling surface is adapted to the surface of the rod body. In this way, when the hoop <NUM> in this embodiment of this application is tightly held onto the rod body, the first profiling surface fits in with the surface of the rod body, and a fitting area is large, so that a pressing force between the elastic pad <NUM> and the rod body acts on a larger surface. This avoids compressive deformation of the rod body.

In some embodiments, as shown in <FIG> or <FIG>, the hoop <NUM> further includes at least one strap accommodation member <NUM>. As shown in <FIG>, each strap accommodation member <NUM> is provided with first through holes <NUM> and second through holes <NUM>, the strap accommodation member <NUM> is disposed, through the first through holes <NUM>, on a part that is of the strap <NUM> and that is configured to hold onto the existing rod body, and a part that is of the strap <NUM> and that is not configured to hold onto the existing rod body is capable of being disposed through the second through holes <NUM>. In this way, the strap accommodation member <NUM> accommodates the part that is of the strap <NUM> and that is not configured to hold onto the existing rod body, appearance neatness of the hoop <NUM> that is present after the hoop <NUM> is fastened on the rod body is ensured. In addition, the strap accommodation member <NUM> can slide along the length direction of the strap <NUM>, to adjust a location of the strap accommodation member <NUM>, so that the strap accommodation member <NUM> can accommodate parts of the strap that have different lengths and that are not configured to hold onto the existing rod body.

There may be one, two, three, or more strap accommodation members <NUM>. This is not specifically limited herein. In some embodiments, as shown in <FIG> or <FIG>, there are two strap accommodation members <NUM>. In this way, the strap accommodation members <NUM> can accommodate parts of the strap that have a large length and that are not configured to hold onto the existing rod body, and the quantity of the strap accommodation members <NUM> is relatively small, so that structural complexity and costs of the hoop <NUM> can be reduced.

The first through holes <NUM> and the second through holes <NUM> may be arranged side by side (that is, an axial direction of the first through holes <NUM> and an axial direction of the second through holes <NUM> are parallel to each other), may be perpendicular to each other (that is, the axial direction of the first through holes <NUM> and the axial direction of the second through holes <NUM> are perpendicular to each other), or may be in another orientation relationship. This is not specifically limited herein. In some embodiments, as shown in <FIG>, the first through holes <NUM> and the second through holes <NUM> are arranged side by side, and the first through holes <NUM> and the second through holes <NUM> are arranged along a thickness direction of the strap <NUM>. In this way, when the strap <NUM> winds around the rod body, the buckle head <NUM> is fastened to a fastening hole <NUM> so that the strap <NUM> is held onto the rod body, and the part that is of the strap <NUM> and that is not configured to hold onto the existing rod body is disposed through the second through holes <NUM>, the part that is of the strap <NUM> and that is not configured to hold onto the existing rod body partially overlaps the part that is of the strap <NUM> and that is held onto the rod body. This enables desirable appearance neatness.

The first through holes <NUM> and the second through holes <NUM> may be independent of each other, or may penetrate through each other. This is not specifically limited herein. In some embodiments, as shown in <FIG>, the first through holes <NUM> and the second through holes <NUM> are independent of each other, to avoid friction between the part that is of the strap <NUM> and that is disposed through the first through holes <NUM> and the part that is of the strap <NUM> and that is disposed through the second through holes <NUM>. In some other embodiments, the first through holes <NUM> and the second through holes <NUM> penetrate through each other. In this way, only one through hole needs to be formed on the strap accommodation member <NUM>. Therefore, the strap accommodation member <NUM> has a simple structure and is easy to fabricate.

In some embodiments, as shown in <FIG>, a surface that is of the strap accommodation member <NUM> and that is configured to fit in with the existing rod body is provided with an anti-slide structure b. In this way, when the hoop <NUM> in this embodiment of this application is tightly held onto the rod body, the anti-slide structure b on the strap accommodation member <NUM> comes into contact with the rod body. This can prevent the hoop <NUM> from sliding down along the rod body.

There are a plurality of structural forms for the anti-slide structure b. This is not specifically limited herein. In some embodiments, as shown in <FIG>, the anti-slide structure b is a plurality of ribs uniformly disposed on the inner surface of the strap accommodation member <NUM>, and the plurality of ribs are arranged intersecting each other.

In some embodiments, the surface that is of the strap accommodation member <NUM> and that is configured to fit in with the existing rod body is a second profiling surface, and the second profiling surface is adapted to the surface of the rod body. In this way, when the hoop <NUM> in this embodiment of this application is tightly held onto the rod body, the second profiling surface fits in with the surface of the rod body, and a fitting area is large, so that a pressing force between the strap accommodation member <NUM> and the rod body acts on a larger surface. This avoids damage to the strap accommodation member <NUM> and the rod body during mutual pressing.

A material of the strap accommodation member <NUM> includes but is not limited to plastic, silica gel, rubber, or metal. In some embodiments, the material of the strap accommodation member <NUM> is silica gel. Silica gel has high toughness and can be prevented from being scratched by the strap <NUM> when sliding along the strap <NUM>.

In some embodiments, the electronic device body is provided with a third through hole, and the electronic device body is disposed on the strap <NUM> through the third through hole. In this way, the electronic device body may slide along the strap <NUM>, to adjust a location of the electronic device body on the strap <NUM>.

In the descriptions of this specification, the specific features, structures, materials, or characteristics may be combined in a proper manner in any one or more of embodiments or examples.
