When people go outside, it may be necessary to hold a beverage bottle or a coffee cup while pulling a pull rod of a suitcase, which is inconvenient to move. For the suitcase in the related art, a side of the suitcase or a side of the pull rod is provided with a holder, and the bottle or the cup can be accommodated in the holder when a user is waiting or walking. However, when the user pulls the suitcase to walk, legs of the user are easy to collide with the holder, so that the suitcase is inconvenient to use. In addition, when the bottle or the cup is accommodated in the holder on the side of the suitcase, the user needs to crouch down to reach the bottle or the cup due to a height limitation of the suitcase, and the bottle and the cup are easy to forget.

Referring to <FIG>, to solve the above problem, the application provides a pull rod <NUM>. The pull rod <NUM> is convenient for the user to accommodate the bottle or the cup. In addition, the bottle or the cup is not easily forgotten and less prone to collide with the user, and it is convenient to use the pull rod <NUM>.

Referring to <FIG>, a first preset direction can be defined as a ±X-axis direction, a second preset direction can be defined as a ±Y-axis direction, and an extension direction of the link assembly <NUM> can be defined as a ±Z-axis direction.

Referring to <FIG>, specifically, the pull rod <NUM> includes a link assembly <NUM>, a handle assembly <NUM>, and a supporting member <NUM>. The handle assembly <NUM> is disposed on the link assembly <NUM>, and the handle assembly <NUM> includes a first handle <NUM> and a second handle <NUM> arranged at intervals along the ±X-axis direction. The supporting member <NUM> is disposed on the handle assembly <NUM>, a side of the supporting member <NUM> facing the link assembly <NUM> is concave, that is, the supporting member <NUM> is concave towards the -Z-axis direction. A storage space <NUM> is defined between the supporting member <NUM>, the first handle <NUM> and the second handle <NUM>, and the storage space <NUM> is capable of accommodating articles such as the bottle, the cup, and the like.

As mentioned above, in the suitcase of the related art, the side of the suitcase or the side of the pull rod is provided with the holder. When the user pulls the suitcase to walk, legs of the user are easy to collide with the holder, so that the suitcase is inconvenient to use. In the pull rod <NUM> provided in an embodiment of the present embodiment, articles such as the bottle, the cup, and the like can be accommodated in the storage space <NUM> defined between the supporting member <NUM>, the first handle <NUM> and the second handle <NUM>. The supporting member <NUM> is configured to support the bottle or the cup, the first handle <NUM>, and the second handle <NUM> is configured to limit the bottle or the cup, thus preventing the bottle or the cup from falling. In this way, it is not necessary to hold the bottle or the cup at all times. Since the bottle or the cup is located between first handle <NUM> and second handle <NUM>, when the user pulls the suitcase <NUM> to walk, legs of the user will not collide with the holder, so that it is convenient to use the suitcase <NUM>. In addition, a height of the bottle or the cup accommodated in the storage space <NUM> is higher than a height of the bottle or the cup accommodated in the side of the suitcase <NUM>. When the bottle or the cup is accommodated in the storage space <NUM>, it is convenient for the user to reach the bottle or the cup. Moreover, the bottle or the cup is not easily forgotten.

In addition, in the pull rod <NUM> provided by the embodiment of the application, the first handle <NUM> and the second handle <NUM> can be configured to form the storage space <NUM> without an additional structure on the link assembly <NUM>, thereby avoiding the link assembly <NUM> of the pull rod <NUM> occupying too much space on devices such as the suitcase <NUM>.

Referring to <FIG> and <FIG>, a distance between the first handle <NUM> and the second handle <NUM> can be denoted as a, and the distance a between the first handle <NUM> and the second handle <NUM> can be greater than or equal to <NUM> millimeters and less than or equal to <NUM> millimeters. In this way, the first handle <NUM> and the second handle <NUM> can be easily gripped by the user. In addition, bottles or cups with different diameters can be accommodated in the storage space <NUM>, and the bottles or the cups can be less prone to shake significantly in the storage space <NUM>. A distance between the two connecting members <NUM> can be denoted as b, and the distance b between the two connecting members <NUM> can be greater than or equal to <NUM> millimeters and less than or equal to <NUM> millimeters. In this way, when the bottle or the cup is accommodated in the storage space <NUM> vertically, two or more bottles or cups can be accommodated side by side in the storage space <NUM>. Alternatively, shorter bottles or cans can be accommodated in the storage space <NUM> horizontally and suitable for a wide range of applications. A depth of the storage space <NUM> can be denoted as c, and the depth c of the storage space is greater than or equal to <NUM> millimeters and less than or equal to <NUM> millimeters. The depth c of the storage space <NUM> can be a size of the storage space <NUM> along the ±Z-axis direction. In this way, stability of the bottle or the cup when accommodated in the storage space <NUM> can be guaranteed, thus preventing the bottle or the cup from falling. Moreover, limiting the size of the storage space <NUM> in all directions can further prevent the pull rod <NUM> from being too great to take up too much space inside devices such as the suitcase <NUM>.

Referring to <FIG>, the supporting portion <NUM> can be provided with a first groove <NUM> configured for accommodating an electronic device <NUM>. Since a center of gravity of the electronic device <NUM> such as a mobile phone or a tablet computer is relatively high, when the electronic device <NUM> is accommodated in the storage space <NUM> vertically, the electronic device <NUM> is prone to tip. Therefore, when the electronic device <NUM> such as the mobile phone or the tablet computer need to be used vertically, the electronic device <NUM> can be accommodated in the first groove <NUM>. Since the storage space <NUM> has a certain depth, the electronic device <NUM> such as the mobile phone and the tablet computer can be accommodated in the first groove <NUM> and abut against the first handle <NUM> or the second handle <NUM>, so as to ensure stability and safety of the electronic device <NUM> such as the mobile phone and the tablet computer, and prevent the electronic device <NUM> from tipping or falling.

Referring to <FIG>, a width of the first groove <NUM> along the ±X-axis direction is denoted as d, and the width d of the first groove <NUM> along the ±X-axis direction can be greater than or equal to <NUM> millimeters and less than or equal to <NUM> millimeters. A length of the first groove <NUM> along the ±Y-axis direction is denoted as e, and the length e of the first groove <NUM> along the ±Y-axis direction can be greater than or equal to <NUM> millimeters and less than or equal to <NUM> millimeters. In this way, electronic devices <NUM> such as mobile phones or tablet computers with different widths and thicknesses or an electronic device <NUM> with a protective case can be accommodated in the first groove <NUM> and suitable for a wide range of applications. A depth of the first groove <NUM> can be denoted as f, and the depth f of the first groove <NUM> can be greater than or equal to <NUM> millimeters and less than or equal to <NUM> millimeters. The depth of the first groove <NUM> can be a size of the first groove <NUM> along the ±Z-axis direction. In this way, stability of the electronic device <NUM> such as the mobile phone and the tablet computer can be ensured when accommodated in the first groove <NUM>, thus preventing the electronic device <NUM> from slipping. In addition, limiting the size of the first groove <NUM> along all directions can further prevent an overall size of the pull rod <NUM> from being too great due to a great size of the supporting portion <NUM>, and prevent the first groove <NUM> from affecting the user gripping the first handle <NUM> and the second handle <NUM>.

Referring to <FIG> and <FIG>, in the same position of each of the at least two connecting members <NUM> can be provided with a second groove <NUM>, the second groove <NUM> can be configured for accommodating the electronic device <NUM>, and two ends of the second groove <NUM> can extend along the second preset direction to an edge of the corresponding connecting member <NUM>. When the electronic device <NUM> such as the mobile phone or the tablet computer need to be used horizontally, the electronic device <NUM> can be accommodated in the second groove <NUM>. Since two ends of the second groove <NUM> extend to the edge of the corresponding connecting member <NUM>, the second groove <NUM> cannot limit a size of the electronic device <NUM> along the ±Y-axis direction when the electronic device <NUM> is used horizontally. Furthermore, a plurality of connecting members <NUM> can improve stability of the electronic device <NUM> accommodated in the second groove <NUM>, and prevent the electronic device <NUM> from tipping or falling.

Referring to <FIG>, a width of the second groove <NUM> along the first preset direction can be denoted as g, and the width g of the second groove <NUM> along the first preset direction can be greater than or equal to <NUM> millimeters and less than or equal to <NUM> millimeters. In this way, electronic devices <NUM> such as mobile phones or tablet computers with different thicknesses or the electronic device <NUM> with the protective case can be accommodated in the second groove <NUM> and less prone to slip in the second groove <NUM>. A depth of the second groove <NUM> can be denoted as h, and the depth h of the second groove <NUM> can be greater than or equal to <NUM> millimeters and less than or equal to <NUM> millimeters. In this way, stability of the electronic device <NUM> such as the mobile phone or the tablet computer accommodated in the second groove <NUM> can be guaranteed, thus preventing the electronic device <NUM> from tipping or falling. In addition, limiting a size of the second groove <NUM> along all directions can further prevent the overall size of the pull rod <NUM> from being too great due to a great size of the connecting member <NUM> or the second handle <NUM>.

Referring to <FIG>, in order to ensure that the devices such as the suitcase <NUM> can be picked up by the second handle <NUM>, the second handle <NUM> needs to be flush with or slightly higher than the first handle <NUM>, so that there is a certain gap between the second handle <NUM> and the devices such as the suitcase <NUM>, so as to grip the second handle <NUM> by the user. When the first handle <NUM> needs to be flush with the second handle <NUM>, the depth of the second groove <NUM> can be a size of inner surfaces of both sides of the second groove <NUM> along the Z-axis direction. When the second handle <NUM> is slightly higher than the first handle <NUM>, the depth of the second groove <NUM> can be a size of an inner surface of the second groove <NUM> proximal to the second handle <NUM> along the Z-axis direction.

Referring to <FIG>, the inner surface of the second groove <NUM> proximal to the second handle <NUM> can be a slope <NUM>. In this way, the electronic device <NUM> such as the mobile phone and the tablet computer can be accommodated in the second groove <NUM> and abut against the slope <NUM>. Not only can the slope <NUM> ensure stability of the electronic device <NUM>, but also improve comfort of the user. A tilt angle of the slope <NUM> can be denoted as θ, and the tilt angle θ of the slope <NUM> can be greater than or equal to <NUM> and less than or equal to <NUM> degrees. When the electronic device <NUM> such as the mobile phone or the tablet computer is tilted to the above angle range, a viewing effect of the screen of the electronic device <NUM> such as the mobile phone or the tablet computer of the user can be best and more comfortable.

Referring to <FIG> and <FIG>, since the second handle <NUM> needs to be gripped by the user to pick up the device such as the suitcase <NUM> and device such as the suitcase <NUM> is usually heavier, a side surface of the second handle <NUM> facing the storage space <NUM> can be provided with a plurality of concave portions <NUM>. The plurality of concave portions <NUM> can adapt to a hand shape of the user, making it more comfortable for the user to grip the second handle <NUM>. In addition, when the bottle or the cup is accommodated in the storage space <NUM> vertically, the plurality of concave portions <NUM> can further able to limit the position of the bottle or the cup, thus prevent the bottle or the cup from sliding along the ±Y-axis direction. In other embodiments, the first handle <NUM> can further be provided with a plurality of concave portions <NUM>, making it more comfortable for the user to grip the first handle <NUM>.

Referring to <FIG>, since it may be necessary to carry a bag while pulling the pull rod <NUM> of the suitcase <NUM> when people go out, the bag is prone to collide with the suitcase <NUM> or legs of the user, which is inconvenient for the user to move. The pull rod <NUM> can be further provided with a hanger <NUM> disposed on the handle assembly <NUM> and/or the supporting member <NUM>. The hanger <NUM> can be configured to hang other articles such as the bag, and the articles hanging on the hanger <NUM> can be less prone to collide with the suitcase <NUM> or legs of the user, thus making it more convenient for the user to travel. The pull rod <NUM> may be provided with a hanger <NUM>, two hangers or more than two hangers. Moreover, both the handle assembly <NUM> and the supporting member <NUM> can be provided with a hanger <NUM>, as long as the hanger <NUM> does not interfere with other structures of the suitcase <NUM>, the present embodiment does not make specific restrictions herein.

Referring to <FIG>, the application further provides a suitcase <NUM>, including a case body <NUM> and the pull rod <NUM> mentioned above, and the pull rod <NUM> is disposed on the case body <NUM>. One side of the case body <NUM> can be provided with an assembly groove <NUM> adapted to a shape of the link assembly <NUM>. The link assembly <NUM> can be embedded in the assembly groove <NUM> to prevent the link assembly <NUM> from protruding from the case body <NUM> to increase the overall size of suitcase <NUM>. Since the first handle <NUM> is connected to the link assembly <NUM>, the case body <NUM> can be pushed by the user via the first handle <NUM>. Since the second handle <NUM> is proximal to a middle position of the case body <NUM>, the case body <NUM> can be picked by the user via the second handle <NUM> to ensure balance of the case body <NUM>.

Referring to <FIG>, the case body <NUM> can be provided with an accommodating groove <NUM> configured to accommodate the handle assembly <NUM> and the supporting member <NUM>, and the accommodating groove <NUM> can be connected to and in communication with the assembly groove <NUM>. A size of the accommodating groove <NUM> can be greater than or equal to a size of the handle assembly <NUM> and the support member <NUM>. The accommodating groove <NUM> can prevent the handle assembly <NUM> and the supporting member <NUM> from protruding from the case body <NUM> to increase the overall size of suitcase <NUM>. Since handles, wheels, etc. of the suitcase <NUM> are taken into account when the size of the suitcase <NUM> is calculated, the pull rod <NUM> does not protrude from the case body <NUM>, so that the suitcase <NUM> can have a greater capacity without increasing the overall size thereof. Furthermore, when the size of the accommodating groove <NUM> is greater than the size of the handle assembly <NUM>, there is a certain distance between the second handle <NUM> and the inner surface of the accommodating groove <NUM>, which is convenient for the user to grip the second handle.

In other embodiments, the above-mentioned pull rod <NUM> can be applied in other devices with push and pull functions such as a trolley bag, a trolley stereo, a trolley and so on, the application does not limit herein.
