[0040] The following describes embodiments of the present invention in detail. 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 only to explain the present invention and are not to be construed as limiting the present invention.

[0041] In the description of the present invention, it should be understood that descriptions involving orientation, such as the orientation or positional relationship indicated by up, down, etc., are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0042] In the description of the present invention, "a plurality" refers to more than two. The use of "first" or "second" is solely for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of the indicated technical features, or implicitly indicating the order of the indicated technical features.

[0043] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0044] Reference Figures 1 to 9A fixing device for a battery simulator according to an embodiment of the present invention includes: a bottom structure component 100 and a top structure component 200. The top structure component 200 is covered on the bottom structure component 100, and forms a receiving cavity for placing the battery simulator between the top structure component 200 and the bottom structure component 100. The bottom structure component 100 is provided with a groove with an opening facing upward, and the top structure component 200 is provided with a groove with an opening facing downward, and the openings of the two grooves correspond to each other, thereby forming a receiving cavity. The size of the bottom structure component 100 is basically the same as that of the top structure component 200, and the two ends of the top structure component 200 are respectively placed on the two ends of the bottom structure component 100.

[0045] In order to facilitate the adjustment of the size of the volume cavity to adapt to battery simulators of different sizes, the bottom structure assembly 100 includes a first bottom structure 101 and a second bottom structure 102, and the first bottom structure 101 is partially installed in a horizontal sliding manner on the second bottom structure 102; similarly, the top structure assembly 200 includes a first top structure 201 and a second top structure 202, and the first top structure 201 is partially installed in a horizontal sliding manner on the second top structure 202; that is, the first bottom structure 101 and the second bottom structure 102 of the bottom structure assembly 100 can slide relative to each other in the horizontal direction, and the first top structure 201 and the second top structure 202 of the top structure assembly 200 can slide relative to each other in the horizontal direction. Figure 4 As shown, the end of the first bottom structure 101 facing the second bottom structure 102 is provided with a first square groove 103, and the end of the second bottom structure 102 facing the first bottom structure 101 is provided with a first square plate 104. The first square plate 104 slides and is inserted into the first square groove 103, thereby achieving the connection between the first bottom structure 101 and the second bottom structure 102. Similarly, the end of the first top structure 201 facing the second top structure 202 is provided with a second square groove, and the end of the second top structure 202 facing the first top structure 201 is provided with a second square plate. The second square plate slides and is inserted into the second square groove, thereby achieving the connection between the first top structure 201 and the second top structure 202. The use of the first square plate 104 and the first square groove 103 to achieve the relative sliding of the first bottom structure 101 and the second bottom structure 102 in the horizontal direction, and the use of the second square plate and the second square groove to achieve the relative sliding of the first top structure 201 and the second top structure 202 in the horizontal direction, has a simple structure and low manufacturing cost, which can effectively reduce manufacturing costs.

[0046] It is conceivable that by providing an elastic member connecting the first bottom structure 101 and the second bottom structure 102, the battery simulator in the receiving chamber can be better positioned. The elastic member can be a spring, an elastic cord, or other structure. Similarly, an elastic member must also be provided between the first top structure 201 and the second top structure 202.

[0047] In some embodiments of the present invention, the bottom structure assembly 100 is provided with a support column foot 160, and the top structure assembly 200 is provided with a positioning groove 230 corresponding to the support column foot 160 on a side facing away from the bottom structure assembly 100. Figure 4 、 Figure 5 As shown, the support column foot 160 is provided on the side of the bottom structure component 100 away from the top structure component 200. There are four support column feet 160, and the four support column feet 160 are arranged in an array. Correspondingly, there are four positioning grooves 230, and the four positioning grooves 230 are also arranged in an array. The size of the positioning grooves 230 is consistent with the size of the support column foot 160, so that the support column foot 160 can be embedded in the positioning groove 230. The arrangement of the positioning column feet and the positioning grooves 230 can realize the stacking arrangement of the fixing device of this embodiment, thereby realizing the following Figure 1 The stacking state shown. Since multiple battery simulators with multiple channels are often used in series, multiple stacking fixtures can be used to achieve stacking of multiple battery simulators, which not only effectively reduces the cable length when multiple battery simulators are connected in series, but also reduces space occupation.

[0048] Furthermore, tie rods 180 are provided at both ends of the bottom structure assembly 100's length. The support legs 160 of the bottom structure assembly 100 can be replaced with rollers, typically universal wheels; the tie rods 180 can then be used to conveniently move the bottom structure assembly 100 around. If multiple fixtures are stacked, the bottom structure assembly 100 at the bottom can be equipped with rollers.

[0049] In some embodiments of the present invention, an adjustment sheet 300 is further included. The adjustment sheet 300 is installed between the bottom structure assembly 100 and the top structure assembly 200 to adjust the vertical distance between the bottom structure assembly 100 and the top structure assembly 200. Figure 1 、 Figure 2 As shown, the adjustment pieces 300 are provided at both ends of the bottom structure assembly 100 in the longitudinal direction. Generally speaking, the number of adjustment pieces 300 provided at both ends of the bottom structure assembly 100 in the longitudinal direction is equal, that is, normally there should be two adjustment pieces 300 provided. However, this does not rule out the possibility that the number of adjustment pieces 300 provided at both ends of the bottom structure assembly 100 in the longitudinal direction is different due to the battery simulator having an irregular structure. Increasing the number of adjustment pieces 300 can increase the height of the accommodating cavity, while reducing the number of adjustment pieces 300 can reduce the height of the accommodating cavity. Thus, by adding or removing adjustment pieces 300, battery simulators of different sizes can be accommodated. The adjustment method is simple and efficient, and the adjustment pieces 300 can be replaced individually, resulting in low manufacturing and use costs.

[0050] In some embodiments of the present invention, the regulating piece 300 partially extends into the accommodating cavity to contact the battery simulator located in the accommodating cavity. Specifically, the regulating piece 300 is preferably made of a material with good thermal conductivity, such as copper. Figure 1 As is known, there are situations where multiple fixing devices are stacked, and since the stacking of multiple battery simulators will affect the heat dissipation of the battery simulator to a certain extent, the adjustment sheet 300 is in contact with the battery simulator, and the adjustment sheet 300 is made of a material with good thermal conductivity, which can achieve heat conduction to the battery simulator, thereby improving the heat dissipation effect of the battery simulator.

[0051] In some specific embodiments of the present invention, the bottom structure assembly 100 is provided with a bottom air duct 130, and the top structure assembly 200 is provided with a top air duct 220, and the top air duct 220 blows air to the bottom air duct 130. Figure 2 、 Figure 4 As shown, there are two top air ducts 220, which are respectively arranged at the two ends of the length direction of the top structural assembly 200. There are also two bottom air ducts 130, which are respectively arranged at the two ends of the length direction of the bottom structural assembly 100. When the top structural assembly 200 is placed on top of the bottom structural assembly 100, the top air duct 220 is aligned with the bottom air duct 130. The top air duct 220 is connected to an air supply device, such as an air duct, or a fan is directly installed on the top structural assembly 200 to supply air into the top air duct 220; the top air duct 220 opens toward one side of the bottom air duct 130, and the bottom air duct 130 opens toward one side of the top air duct 220. The top air duct 220 supplies air to the bottom air duct 130, and an air outlet is provided at the end or one side of the bottom air duct 130.

[0052] Further, refer to Figure 5 As shown, the top structure component 200 is preferably provided with a mounting hole 260 communicating with the top air duct 220, and a fan is installed in the mounting hole 260 to supply air to the top air duct 220; the bottom structure component 100 is provided with a second strip hole 190 penetrating the bottom structure component 100 at a position corresponding to the bottom air duct 130, and the air from the top air duct 220 is blown vertically downward into the bottom air duct 130, and then discharged through the second strip hole 190 of the bottom structure component 100. Figure 9 As shown, a plurality of second strip-shaped holes 190 are provided, and the plurality of second strip-shaped holes 190 are evenly spaced along the length direction of the bottom pipe portion.

[0053] In some embodiments of the present invention, the adjustment piece 300 is disposed between the top air duct 220 and the bottom air duct 130, and the adjustment piece 300 is provided with a ventilation hole 320 passing through the adjustment piece 300. Figure 3 、 Figure 6The ventilation holes 320 shown are long strip-shaped holes. There are multiple ventilation holes 320 and they are spaced apart along the length direction of the adjustment plate 300. Setting the ventilation holes 320 as long strips can not only ensure the structural strength of the adjustment plate 300, but also facilitate cooling of the adjustment plate 300.

[0054] It should be understood that when multiple adjustment sheets 300 are provided between the top structure assembly 200 and the bottom structure assembly 100, the multiple adjustment sheets 300 are stacked and all ventilation holes 320 of the multiple adjustment sheets 300 are aligned in the vertical direction, thereby ensuring smooth passage of wind.

[0055] In some embodiments of the present invention, the bottom structure assembly 100, the top structure assembly 200 and the adjustment piece 300 are connected by a plug-in plate 400. Figure 2 、 Figure 3 As shown, the bottom structure assembly 100 has a slot 110, the top structure assembly 200 has a first insertion hole 210, and the adjustment plate 300 has a second insertion hole 310. The insert plate 400 passes through the first insertion hole 210 and the second insertion hole 310 in sequence and is inserted into the slot 110. The first bottom structure 101 and the second bottom structure 102 of the bottom structure assembly 100 are both provided with slots 110. Similarly, the first top structure 201 and the second top structure 202 of the top structure assembly 200 are both provided with first insertion holes 210, and each adjustment plate 300 is provided with a second insertion hole 310. The top structure assembly 200 has a radially protruding long plate. The first insertion hole 210 vertically penetrates the long plate, and the second insert plate 400 also penetrates the adjustment plate 300. When the adjustment plate 300 is installed between the bottom structure assembly 100 and the top structure assembly 200, the second insertion hole 310 aligns with the slot 110. The method of connecting the bottom structure assembly 100 , the top structure assembly 200 and the adjustment piece 300 through the inserting plate 400 is simple, efficient and has low manufacturing cost.

[0056] It should be noted that the cross-sectional dimensions of the plugboard 400, the dimensions of the slot 110, the first plug hole 210 and the second plug hole 310 are all consistent. When the plugboard 400 passes through the second plug hole 310 and is inserted into the slot 110, the plugboard 400 can position the adjustment plate 300, thereby aligning the ventilation holes 320 of multiple adjustment plates 300.

[0057] In some embodiments of the present invention, the bottom structure assembly 100 is provided with a first connecting member 120, the plug plate 400 is provided with a second connecting member 410, and the first connecting member 120 and the second connecting member 410 are connected by a first elastic member. Figure 2 、 Figure 5As shown, two first connectors 120 are provided, and the two first connectors 120 are spaced apart. Correspondingly, two second connectors 410 are also provided, and both second connectors 410 are connected to the plugboard 400, for example, by welding. The spacing between the two second connectors 410 is consistent with the spacing between the two first connectors 120. The two first connectors 120 and the two second connectors 410 correspond one-to-one and are both connected by a first elastic member. The first elastic member can be a spring, an elastic pull rope, or other structure. When the plugboard 400 is inserted into the slot 110, the first elastic member is in a stretched state. The provision of the first elastic member ensures the stability of the connection between the bottom structure assembly 100 and the top structure assembly 200.

[0058] In some embodiments of the present invention, a position limiting assembly 500 is further included. The position limiting assembly 500 is installed on the bottom structure assembly 100 and is used to fix the position of the battery simulator. Figure 3 As shown, the bottom structure assembly 100 is provided with a first strip hole 140 that passes through the bottom structure assembly 100, and the limiting assembly 500 includes a limiting piece 510 and a third connecting member 520. The limiting piece 510 is partially inserted into the first strip hole 140 and can slide along the first strip hole 140; the third connecting member 520 is used to connect the limiting piece 510 and the bottom structure assembly 100 to achieve the relative position fixation of the limiting piece 510 and the bottom structure assembly 100. The first bottom structure 101 and the second bottom structure 102 are both provided with a first strip hole 140, and the first bottom structure 101 and the second bottom structure 102 are both provided with two first strip holes 140 spaced apart. The limiting piece 510 includes a pin shaft 511 protruding toward one side, and there are two pin shafts 511, which are respectively inserted into the two first strip holes 140. Two first strip holes 140 are provided, and the two pins 511 of the limiting piece 510 are respectively passed through the two first strip holes 140 , which can ensure that the state of the limiting piece 510 does not change when the limiting piece 510 slides along the length direction of the first strip holes 140 .

[0059] Furthermore, four limiting pieces 510 are provided, two limiting pieces 510 are installed on the first bottom structure 101, and two limiting pieces 510 are also installed on the second bottom structure 102. Generally speaking, a battery simulator is provided with four column feet, so four limiting pieces 510 are provided to limit the positions of the four column feet.

[0060] Reference Figure 8As shown, the third connecting member 520 can be an elastic drawstring or a plate buckle, a pin buckle or other structure, taking the plate buckle or pin buckle as an example; the limiting plate 510 is provided with two pins 511, which are defined as the first pin 511 and the second pin 511 for ease of expression; the first pin 511 is connected to the first connecting belt, and the end of the first connecting belt is provided with a locking pin, and the second pin 511 is connected to the second connecting belt, and the second connecting belt is provided with a plurality of through holes for the locking pins to pass through at intervals along its length. When the limiting plate 510 slides along the strip hole to a position against one of the column feet of the battery simulator, the first connecting belt and the second connecting belt are wrapped around one of the supporting column feet 160, and the locking pin of the first connecting belt is inserted into one of the through holes of the second connecting belt, so that the limiting plate 510 is tightly pressed against one of the column feet of the battery simulator. The same operation is performed four times, thereby limiting the sliding of the battery simulator along the length direction of the strip hole.

[0061] It is conceivable that the third connecting member 520 can also be an elastic pull rope. If the elastic pull rope solution is adopted, the bottom structure component 100 must be partially lifted so that the elastic pull rope can be placed on one of the support column feet 160 of the bottom structure component 100.

[0062] The limiting piece 510 and the supporting column foot 160 are connected by the third connecting member 520, so that the limiting piece 510 and the battery simulator are tightly pressed together, effectively utilizing the existing structure, thereby reducing structural parts, not only facilitating processing, but also reducing manufacturing costs.

[0063] In some embodiments of the present invention, the bottom structure assembly 100 is provided with a receiving groove 150, and the limiting piece 510 can be embedded in the receiving groove 150; the receiving groove 150 is provided on the sliding path of the limiting piece 510. Figure 3 、 Figure 8 As shown, the first bottom structure 101 is provided with a receiving groove 150, and the second bottom structure 102 is also provided with a receiving groove 150. The purpose of providing the receiving groove 150 is to facilitate the placement of the limiting piece 510. When the limiting piece 510 is inserted into the receiving groove 150, the upper surface of the limiting piece 510 is flush with the upper surface of the bottom structure assembly 100, so that the upper surface of the bottom structure assembly 100 is a flat surface, thereby facilitating the battery simulator to slide into or out of the fixing device along the length direction of the first strip hole 140.

[0064] In some embodiments of the present invention, reference Figure 8As shown, the receiving groove 150 can accommodate two limiting pieces 510 at the same time, and the two first strip holes 140 arranged at intervals both pass through the receiving groove 150. Since the limiting pieces 510 need to slide in or out of the receiving groove 150, the two limiting pieces 510 are provided with inclined surfaces on the opposite sides of the receiving groove 150, and the two opposite sides of the receiving groove 150 are also provided with inclined surfaces to facilitate the limiting pieces 510 to slide in and out of the receiving groove 150. When placing the battery simulator into the fixing device along the width direction of the bottom structure assembly 100, the connection between the third connecting member 520 and the bottom structure assembly 100 must be untied first, and then the limiting piece 510 must be slid into the receiving groove 150, and then the battery simulator must be placed, and finally the limiting piece 510 must be slid out of the receiving groove 150, and the third connecting member 520 must be connected to the bottom structure assembly 100, so as to achieve the limitation of the battery simulator. Similarly, when removing the battery simulator from the fixing device along the width direction of the bottom structure assembly 100, the connection between the third connecting member 520 and the bottom structure assembly 100 must be released first, and then the limiting piece 510 is slid into the receiving groove 150, and finally the battery simulator is removed.

[0065] Reference Figure 10 As shown, the two limiting plates 510 are located in the accommodating groove 150, and the pin shaft 511 between the two limiting plates 510 is relatively close; it is conceivable that an elastic pull rope can be connected between the pin shafts 511 of the two limiting plates 510 so that the two limiting plates 510 can be placed in the accommodating groove 150 at the same time.

[0066] In some embodiments of the present invention, the bottom structure assembly 100 is provided with a slide groove 170, and the top structure assembly 200 is provided with a positioning piece 240, and the positioning piece 240 is slidably installed in the slide groove 170. Figure 2 、 Figure 7 As shown, the bottom structure assembly 100 includes an upwardly extending plate structure, on which a slide 170 is disposed. The top structure assembly 200 includes a downwardly extending positioning piece 240 that slides into the slide 170. The slide 170 and positioning piece 240 are provided to pre-position the connection between the bottom structure assembly 100 and the top structure assembly 200. When the positioning piece 240 is inserted into the slide 170, the slot 110 and the first receptacle 210 are aligned, facilitating the installation of the adjustment piece 300.

[0067] It should be understood that multiple slide grooves 170 are provided along the length of the bottom structure assembly 100, and the multiple slide grooves 170 are spaced apart. The first bottom structure 101 and the second bottom structure 102 each have at least one slide groove 170. Similarly, the first top structure 201 and the second top structure 202 each have at least one positioning piece 240.

[0068] In some embodiments of the present invention, a top pressure plate 250 is further included. The top pressure plate 250 is installed in the accommodating cavity and is connected to the top structure assembly 200 through a second elastic member 251. Figure 4 As shown, the second elastic block is generally a spring. There are generally two top pressure plates 250, a first top structure 201 connected to a top pressure plate 250, and a second top structure 202 connected to a top pressure plate 250. When the battery simulator is installed in the fixture, the second elastic member 251 is in a compressed state, thereby being able to push the top pressure plate 250 to press tightly on the battery simulator. The provision of the top pressure plate 250 can limit the battery simulator located in the fixture in the vertical direction, reducing the movement of the battery simulator in the vertical direction in the fixture. At the same time, when the fixture shakes or collides, the top pressure plate 250 can play a certain buffering role, thereby reducing or avoiding damage to the battery simulator.

[0069] According to the fixing device of the embodiment of the present invention, the stability of the battery simulator can be ensured by setting the limiting component 500 to limit the battery simulator; the bottom structure component 100 and the top structure component 200 are both composed of two parts that can slide horizontally with each other, thereby realizing the adjustment of the size of the volume cavity in the horizontal direction; the adjustment plate 300 is installed on the bottom structure component 100 and the top structure component 200 to adjust the distance between the bottom structure component 100 and the top structure component 200 in the vertical direction, thereby realizing the adjustment of the size of the volume cavity in the vertical direction; by adjusting the volume cavity in the horizontal and vertical directions, the applicability of the fixing device is greatly improved.

[0070] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the scope of the present invention.
