[0002] Chinese utility model patent No. CN217532810U discloses a bracket structure for an electric vehicle, which is used to carry a battery-swap battery, and the battery-swap battery is electrically connected to the drive motor through a battery-swap connector arranged on the bracket, so that the battery-swap heavy truck can obtain continuous power. The bracket of the prior art is provided with a guide seat and a positioning pin, so that the battery-swap battery can be automatically calibrated and aligned during the falling process. However, after the battery-swap battery is installed on the electric vehicle, during driving, the bumps and vibrations generated by the electric vehicle driving on the road will be transmitted to the battery-swap battery through the positioning pins. In addition to reducing the service life of the battery-swap battery, the hard-contact positioning pins and positioning holes can no longer guarantee the assembly accuracy under wear after multiple plugging and unplugging. In view of this, it is necessary to develop a guiding and positioning method that combines flexibility and rigidity. Utility Model Content

[0003] In response to the defects in the prior art, the purpose of the present utility model is to provide a guide column that combines flexibility and rigidity. The guide column has different stiffness in different working states. In addition to having a good guiding function, it can also play a buffering role after the battery replacement is installed in place, thereby increasing the service life of the battery replacement.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A guide column is provided for being installed on a battery exchange base to guide and position a battery exchange battery. The guide column includes a fixed installation part and a floating pin installed on the fixed installation part. A first limiting part is provided between the lower end of the floating pin and the fixed installation part. Before the battery exchange battery is installed on the battery exchange base, the first limiting part has a first position that cooperates with the fixed installation part. After the battery exchange battery is installed on the battery exchange base, the first limiting part has a second position that is separated from the fixed installation part.

[0006] Furthermore, an elastic portion is provided between the floating pin and the fixed mounting portion, and when the battery-changing battery leaves the battery-changing base, the elastic portion drives the first limiting portion to reset from the second position to the first position.

[0007] Furthermore, a movable mounting sleeve is provided at the lower end of the floating pin, and the movable mounting sleeve is detachably connected to the floating pin.

[0008] Furthermore, the elastic part is a rubber sleeve, the inner side of the elastic part and the outer side of the movable installation sleeve are vulcanized into one, and the outer side of the elastic part and the inner side of the fixed installation part are vulcanized into one.

[0009] Furthermore, a second limiting portion is provided between the upper end of the movable installation sleeve and the fixed installation portion.

[0010] Furthermore, the second limiting portion includes a limiting block fixedly mounted on the movable mounting sleeve and a flexible portion extending outward from the limiting block to cover an upper end of the fixed mounting portion.

[0011] Furthermore, the limiting block and the flexible portion are an integrated structure, and the second limiting portion and the movable mounting sleeve are detachably connected.

[0012] Furthermore, the fixed installation portion and the first limiting portion are respectively in the shape of a hollow cylinder, and the outer diameter of the first limiting portion is not greater than the inner diameter of the fixed installation portion.

[0013] Furthermore, the first limiting portion includes a mounting sleeve extending upward, the lower end of the floating pin is detachably connected to the mounting sleeve, and the elastic portion is arranged between the mounting sleeve and the fixed mounting portion.

[0025] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0026] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0028] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0029] See also Figures 1 to 5 As shown, the first embodiment of the utility model provides a guide column 10, which is used to be installed on the battery exchange base 100 to guide and position the battery exchange battery (not shown). The battery exchange base 100 is used to be installed on the battery exchange vehicle (not shown) to carry the battery exchange battery. Preferably, the bottom of the battery exchange battery is provided with a guide sleeve (not shown) matching the guide column 10. The guide sleeve is made of a material with strong wear resistance, which can improve the service life of the battery exchange battery. The cooperation between the guide column 10 and the guide sleeve can realize the precise positioning of the battery exchange battery, so that the battery exchange interface (not shown) on the battery exchange battery is accurately docked with the battery exchange connector 30 on the battery exchange base 100. Furthermore, the battery exchange base 100 is preferably provided with a coarse guide structure 40. After the coarse step guiding positioning of the coarse guide structure 40, it can ensure that the guide column 10 and the guide sleeve are initially aligned. The battery exchange base 100 has a battery exchange bottom frame 20, and a plurality of buffer pads 50 are arranged between the battery exchange bottom frame 20 and the battery exchange battery. The buffer pads 50 buffer and protect the vibration of the battery exchange battery in the vertical direction. However, in the horizontal direction, since the battery exchange battery is closely matched with the guide column 10, the battery exchange vehicle will transfer the impact load to the battery exchange battery when encountering a bumpy road during driving. Therefore, it is necessary to set the guide column 10 to have a shock-absorbing effect.

[0030] In order to achieve the above-mentioned purpose, the guide column 10 includes a hollow fixed installation part 101 and a floating pin 11 installed on the fixed installation part 101, and a first limiting part 14 is also provided between the lower end of the floating pin 11 and the fixed installation part 101. A mounting plate 12 is fixedly provided on the outer periphery of the fixed installation part 101, and the fixed installation part 101 can be fixedly installed on the battery replacement bottom frame 20 through a through hole 120 provided on the mounting plate 12, for example, by bolt connection. The floating pin 11 includes a conical top 111 and an assembly hole 110 arranged near the conical top 111, and the assembly hole 110 can better apply force during the installation of the floating pin 11. Similarly, a clamping hole 141 is also provided on the first limiting part 14, and the clamping hole 141 is preferably multiple. By grabbing the clamping hole 141, the first limiting part 14 can be more easily assembled to the floating pin 11. Preferably, a mounting sleeve 114 is provided through the center of the first limiting part 14.

[0031] like Figure 4 As shown, before the battery-changing battery is installed on the battery-changing base 14, the first limiting portion 14 has a first position that cooperates with the fixed mounting portion 101. When the first limiting portion 14 is in the first position, it can prevent the floating pin 11 from shaking horizontally relative to the fixed mounting portion 101; as shown in FIG. Figure 5As shown, after the battery-exchange battery is installed on the battery-exchange base 100, the floating pin 11 bears part or all of the weight of the battery-exchange battery, thereby causing a downward displacement, so that the first limiting portion 14 has a second position separated from the fixed mounting portion 101. When the first limiting portion 14 is in the second position, the lower end of the floating pin 11 is no longer constrained in the horizontal direction, so the floating pin 11 can produce horizontal shaking in a local range relative to the fixed mounting portion 101.

[0032] Furthermore, an elastic portion 103 is provided between the floating pin 11 and the fixed mounting portion 101, and the elastic portion 103 drives the first limit portion 14 to reset from the second position to the first position after the battery-changing battery leaves the battery-changing base. Preferably, before the battery-changing battery is installed on the guide column 10, the elastic portion 103 provides an upward preload force to the floating pin 11, and during the process of installing the battery-changing battery on the guide column 10, the floating pin 11 is pushed to move downward, thereby increasing the preload force, and when the battery-changing battery leaves the battery-changing base, the elastic portion 103 rebounds, thereby driving the first limit portion 14 to reset from the second position to the first position. Obviously, in some other embodiments, before the battery-changing battery is installed on the guide column 10, the elastic portion 103 may not provide a preload force, and the rebound force can be provided as long as the elastic portion 103 is forced to deform during the falling process of the battery-changing battery, which will not be elaborated.

[0033] Furthermore, the floating pin 11 includes a conical top 111, an assembly hole 110, a first mounting portion 112 and a second mounting portion 113 from top to bottom, a movable mounting sleeve 102 is provided on the first mounting portion 112, and the first limiting portion 14 is installed on the second mounting portion 113 through the mounting sleeve 114. Preferably, the movable mounting sleeve 102 and the floating pin 11 are detachably connected, and the elastic portion 103 is arranged between the movable mounting sleeve 102 and the fixed mounting portion 101. The advantage of such a design is that it is more convenient for assembly. In this embodiment, the elastic portion 103 is a rubber sleeve, and the inner side of the elastic portion 103 is vulcanized into one with the outer side of the movable mounting sleeve 102, and the outer side of the elastic portion 103 is vulcanized into one with the inner side of the fixed mounting portion 101. In some other embodiments, the elastic portion 103 can also be made of a spring or other elastic material.

[0034] Preferably, a second limiting portion 15 is further provided between the upper end of the movable mounting sleeve 102 and the fixed mounting portion 101. Since the first limiting portion 14 is installed at the lower end of the floating pin 11, the upper end of the floating pin 11 has a larger swinging space. The second limiting portion 15 can limit the swinging amplitude of the floating pin 11, thereby improving the accuracy of the guide positioning. The second limiting portion 15 includes a limiting block 151 fixedly installed on the movable mounting sleeve 102 and a flexible portion 152 extending outward from the limiting block 151 to cover the upper end of the fixed mounting portion 101, wherein the limiting block 151 can be made of a flexible, rigid or rigid-flexible material, which can achieve the purpose of limiting the range of movement of the floating pin 11, wherein the flexible portion 152 covers the upper end of the fixed mounting portion 101 from the inside to the outside, so that the gap between the limiting block 151 and the fixed mounting portion 101 is not exposed to the outside, thereby achieving a dustproof and waterproof effect. Preferably, the limiting block 151 and the flexible portion 152 are an integral structure, and the second limiting portion 151 and the movable mounting sleeve 102 are detachably connected, for example, by threaded connection or interference fit.

[0035] The fixed mounting portion 101 and the first limiting portion 14 are respectively in the shape of a hollow cylinder, and the outer diameter of the first limiting portion 14 is smaller than the inner diameter of the fixed mounting portion 101, that is, in this embodiment, the first limiting portion 14 is embedded in the inner cavity of the fixed mounting portion 101, and the floating pin 11 moves downward to push the first limiting portion 14 away from the inner cavity of the fixed mounting portion 101. Under the action of the rebound force of the elastic portion 103, the first limiting portion 14 rises as the downward thrust on the floating pin 11 decreases, and finally, when the battery-exchange battery leaves the battery-exchange base, the first limiting portion 14 returns to the inner cavity of the fixed mounting portion 101. Preferably, the upper end surface of the first limiting portion 14 is provided with a chamfer (not shown), which is more conducive to its resetting.

[0036] See also Figure 6As shown, the guide column 10 provided in the second embodiment of the utility model also includes a fixed mounting portion 101 and a floating pin 11 installed on the fixed mounting portion 101, and a first limiting portion 14 is also provided between the lower end of the floating pin and the fixed mounting portion 101. Different from the first embodiment, in the second embodiment, the first limiting portion 14 includes a mounting sleeve 114 extending upward, and the lower end of the floating pin 11 is detachably connected to the mounting sleeve 114, and the elastic portion 103 is arranged between the mounting sleeve 114 and the fixed mounting portion 101. Compared with the first embodiment, the second embodiment can reduce one movable mounting sleeve 102, or it can be considered that the movable mounting sleeve 102 in the first embodiment becomes a part of the first limiting portion 14 in the second embodiment. In the second embodiment, the bottom of the floating pin 11 can be set as a bolt, and the upper end of the mounting sleeve 114 can be set as an internal threaded countersunk hole that cooperates with the bolt, thereby realizing the aforementioned detachable connection. Obviously, a protrusion can also be set on the lower end mounting portion 112 of the floating pin 11, and a groove can be set in the mounting sleeve 114. The same technical effect can be achieved by realizing a snap fit between the protrusion and the groove, which will not be elaborated here.

[0037] The utility model also provides a battery-swap vehicle, which has a battery-swap base 100 for carrying a battery-swap battery. The battery-swap base 100 is provided with a plurality of the aforementioned guide columns 10, thereby simultaneously achieving guiding positioning and buffering effects on the battery-swap battery, thereby improving the service life of the battery-swap battery.

[0038] The above embodiments are only to illustrate the basic principles and characteristics of the present invention. The present invention is not limited by the above embodiments. Without departing from the spirit and scope of the present invention, the present invention may be subject to various changes and modifications, which are within the scope of the present invention.
